Abstract

The utility model relates to an improved knee joint, which is mainly characterized in that a rotary part is sheathed in a knee joint body through a shaft center and is driven to rotate by using the shaft center as a center. A unidirectional bearing is arranged in a rotary device of the rotary part, so that the rotary part can be quickly restored counterclockwise with the help of the restoring force of a cushioning device and the unidirectional bearing of the rotary part, and can be slowly bent clockwise with the help of the cushioning device and larger friction force. With the to-and-fro movement of the rotary part, disabled people can effectively use an artificial limb to move more conveniently.

Description

Improved knee joint

This utility model relates to a kind of artificial limb knee-joint device, and the artificial limb that particularly a kind of individuals with disabilities of allowing uses can be more convenient and the improved knee joint of safe handling.

Individuals with disabilities in the society now, can increase its action property by the artificial limb structure, and be to make artificial limb work out knee joint structure then as the bending walking of foot as the foot knee, allow artificial limb more as the bending of people's foot walking, allow the more convenient walking of individuals with disabilities by this artificial limb; Though yet the artificial limb knee-joint structure has and the foot identical functions; because artificial limb is a kind of frame for movement all the time; need individuals with disabilities's utilization to lift actions such as lower limb and swing; effectively motion; but knee joint structure now; as No. the 203742nd, Taiwan patent announcement " kneed improvement structure "; its Fastening device utilizes rotating shaft; allow the Fastening device be center rotation with the axostylus axostyle; because artificial limb is not the some of own health eventually; uncontrollable quite flexible, thus usually can be when wanting crooked rotation too fast, cause as angle can't the application of force compressing the packing cover when excessive; cause artificial limb to bend to the right angle fast; allow the individuals with disabilities not have to support and fall injured, and when bending after homing very fast, allow the individuals with disabilities can only the small step walking etc. use inconvenience and unsafe problems.

The purpose of this utility model is that a kind of improved knee joint will be provided, and promptly provides a kind of crookedly slowly in clockwise, replys knee joint structure fast counterclockwise.

The purpose of this utility model is achieved in that

A kind of improved knee joint is characterized in that: socket one is the rotating part of center of rotation with this axle center on the axle center of this knee joint main body; This rotating part mainly includes a rotary apparatus, and a unilateral bearing is set in this rotary apparatus, and the rear end of this rotary apparatus links to each other with buffer unit upper end; This kneed rotating part is the slow shape that is rotated counterclockwise fast and turns clockwise.

A gum elastic is installed in this knee joint main body top.

This utility model mainly is to insert unilateral bearing in the rotary apparatus, it utilizes the restoring force of buffer unit and the unilateral bearing of rotating part when allowing rotating part with counterclockwise answer, and homing fast, when rotating part utilizes buffer unit and bigger friction when crooked and can be crooked slowly with clockwise, by this action that comes and goes, allow the individuals with disabilities effectively use artificial limb, make action more convenient.

This utility model structure flexibly, apply on individuals with disabilities's the artificial limb more convenient, the safety of its action.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

See also Fig. 1,2, this utility model is to utilize axle center 3000 that rotating part 2000 is socketed in the knee joint Zheng Jie main body 1000, allow the rotating part 2000 be center rotation with axle center 3000, be provided with one in knee joint main body 1000 belows and articulate sleeve 1100, pole 6000 is fixing, and its pole can articulate structures such as ankle and sole 6000 times; Be provided with a perforation 1010 in articulating sleeve 1100 tops, utilize latch 5200 buffer unit 5000 can be combined in knee joint main body 1000 belows, making buffer unit 5000 is that the center rotation is used with latch 5200, the perforation 5010 of its buffer unit 5000 upper ends, can be connected by perforation 2110 with the latch 5300 of rotary apparatus 2100 rear ends, reach when rotating part 2000 when turning clockwise, utilize buffer unit 5000 bending slowly, be difficult for crooked fast and the generation imbalance, the individuals with disabilities is caused danger; A gum elastic 5100 is also installed in its knee joint main body 1000 tops, the impact strength in the time of can absorbing rotating part 2000 and go back to.

Install an articulated section 6100 on individuals with disabilities's thigh additional, with loam cake 4000 and articulated section 6100 combinations, its loam cake 4000 utilizes latch 5400 to combine with the perforation 2130 of rotary apparatus 2100, and making when mobile with axle center 3000 is that center curvature uses.

Its rotating part 2000 is to add a sleeve 2200 and a unilateral bearing 2300 in a gap 2220 in the rotary apparatus 2100, these sleeve 2200 inner surfacies are an attrition surface 2210, these unilateral bearing 2300 outsides are a surfaces of revolution 2310, these rotary apparatus 2100 tops are provided with an aperture 2120, establish one in this aperture 2120 and press key 2600, in rotary apparatus 2100 both sides one plate washer 2400 is installed respectively, 2500, utilize screw 3100 to be locked on the knee joint main body 1000 in axle center 3000 and rotating part 2000, with axle center 3000 is center of rotation rotation utilization, its plate washer 2400, be respectively equipped with bearing 2410 in 2500,2510, can make rotating part 2000 more smooth and easy with axle center 3000 rotations, the perforation 5010 that adds buffer unit 5000 tops and rotary apparatus 2100 junction also is provided with a bearing 5020, also can make rotation more smooth and easy.

See also shown in Fig. 3,4, its loam cake 4000 of this utility model rotates to buffer unit 5000 can't cushion the time with axle center 3000 again, the speed when its buffer unit 5000 also can slow down bending; In loam cake 4000, be provided with a screw 4100, utilize the position of screw 4100 adjustable seamless bars 4200, can adjust the size of the application of force by shift in position.

See also Fig. 5, shown in 6,2300 of its unilateral bearings of this utility model allow to be rotated counterclockwise, so when rotating part 2000 this unilateral bearing 2300 competence exertion functions and rotating fast when being rotated counterclockwise, when rotating part 2000 can not use because of unilateral bearing 2300 when turning clockwise, so will drive unilateral bearing 2300 during rotation, become the surfaces of revolution 2310 rotations with unilateral bearing 2300, and because of attrition surface 2210 internal rotation of the surfaces of revolution 2310 at sleeve 2200, it is big that the area that will cause rubbing becomes, reach quick when being rotated counterclockwise, and motion mode slowly when turning clockwise makes the more convenient use of individuals with disabilities; Its rotary apparatus 2100 tops are provided with an aperture 2120, in aperture 2120, be provided with one and press key 2600, to oppress sleeve 2200 after pressing key 2600 stressed diminishes gap 2220, cause the friction of the surfaces of revolution 2310 and attrition surface 2210 to become big, just as brake function and can't rotating, thus only need less pressure to stop the rotation, except can't be on pressure key 2600 angle of the application of force, surpass 30 degree and also can stop the rotation, can allow the individuals with disabilities safer.

In sum, its disclosed improved knee joint, not only safety and more convenient use, the effect of its enhancement has been had the patent requirement of advance and practicality more during utilization; But the above, it only is of the present utility model one preferable enforcement example, when can not with as limiting the scope that this utility model is implemented, all equalizations of being done according to this utility model claim change or modify, and must belong in the scope that this utility model patent contains.
