In the state that the brake is loosened, a brake nut pushes in a groove through a round pin, a brake lever move upwards, and the lower end part of the brake lever is disengaged from a brake member; in the brake state, the cam rotates counterclockwise, the round pin pushes the brake nut and the brake lever to downwards move under the action of the cam, the lower end part of the brake lever accords to the brake member and the brake member contact a brake hub on the caster.
Description
Technical field
This utility model relates to the castor brake system on a kind of sick bed, in order to technical field of medical instruments.
Background technology
In the prior art, be provided with four castors in four bights of sick bed, the place is provided with braking mechanism at castor, and when depressing brake component, the brake hub on brake component and the castor contacts, and realizes brake function.When take-off the brake spare, remove braking state, this brake can only be carried out some occasion inconvenient operation on the castor side.
The content of utility model
The purpose of this utility model is to provide a kind of castor brake system that can carry out the castor brake operation at a distance.The castor brake system is made up of two parts, brake gear and middle control castor, and two parts combined effect reaches convenient purpose of braking.
The technical solution of the utility model is: a kind of castor brake gear of sick bed, the brake pipe that is being connected on the base, foot-operated and brake pipe is fixed together, and is welded with two round steel on the brake pipe, round steel passes the slotted hole on the drive block, and described drive block and brake hexagonal steel are fixed together.When stepping on when foot-operated, the foot-operated brake pipe rotating certain angle that drives, brake pipe drives drive block by round steel and the brake hexagonal steel and then turns over corresponding angle.The inner hexagonal hole of the cam of control in the castor during described brake hexagonal steel passes, the cam in the castor just can be followed the hexagonal steel that brakes and rotated together like this.Described cam is provided with groove, and under the brake releasing orientation, the brake nut and the round pin of brake lever upper end withstand in this groove, and the end portion and the brake member of brake lever are separated; Under the state that brake is checked, cam turns over certain angle counterclockwise, promotes round pin, brake nut and move down with the brake lever of its hinge joint, and the end portion and the brake member of brake lever are meshed, the brake hub on the brake member contact castor.That is to say this utility model can control by the rotation of brake hexagonal steel in control castor brake or unclamp.
This utility model compared with prior art has following advantage:
Owing to can control brake operation at a distance by brake pipe, therefore also can operate the foot-operated middle part that is installed in sick bed, be suitable for the care-giver and use handled easily.

The concrete mode of implementing:
Referring to accompanying drawing 2, a kind of castor brake gear of sick bed, the brake pipe 20 that is being connected on the base 17, foot-operated 22 and brake pipe 20 same axle center be fixed together, welded two round steel on the brake pipe 20, described round steel passes the slotted hole on the drive block 18.Drive block 18 and brake hexagonal steel 21 are fixed together, and control the inner hexagonal hole of the cam 9 of 19 li of castors during brake hexagonal steel 21 passes, and cam 9 just can be followed brake hexagonal steel 21 and be rotated together.
The upper part of described brake lever 3 and 10 hinge joints of brake nut, end portion and 14 riveted joints of brake lever engaging tooth.Brake member 6 is provided with brake member engaging tooth 5.Under state was checked in brake, brake lever engaging tooth 14 and brake member engaging tooth 5 were meshed.
Do the roller contact by round pin 2 between described brake nut 10 and the cam 9.Make when cam 9 rotates, can guide brake nut 10 and brake lever 3 to move up and down.
Be provided with spring 11 between described plastics fixed cover 8 and the brake nut 10, this spring 11 has the trend that brake nut 10 and brake lever 3 are moved up.
Be provided with spring 7 between described wheel hub 15 and the brake member 6, this spring 7 has makes brake member 6 that the trend that breaks away from brake hub 16 be arranged.
Described brake hub 16 is rubber rims of a truncated cone-shaped, and described brake member 6 is provided with the cambered surface of corresponding truncated cone-shaped, and during brake, the arcwall face of brake member 6 and brake hub 16 match.Be marked with the tooth of some projections on brake member 6 arcwall faces, can increase the frictional force between arcwall face and the brake hub 16.
As accompanying drawing 2, step on foot-operated 22 of right-hand member, foot-operated 22 drive brake pipe 20 rotating certain angle, brake pipe 20 drives drive block 18 by two round steel on it and brake hexagonal steel 21 turns over corresponding angle, brake hexagonal steel 21 also drives 9 on cam in the castor with turning over identical angle, make this utility model be in the brake releasing orientation shown in the accompanying drawing 3,6.Described cam 9 is provided with groove; Under the brake releasing orientation, brake nut 10 withstands in this groove by round pin 2, and brake lever 3 moves up, and brake lever 3 end portions and brake member 6 are separated; Shown in accompanying drawing 4,7, under braking state, cam 9 rotates counterclockwise, and round pin 2 promotes brake nut 10 and brake lever 3 and moves down under the effect of cam 9, the end portion of brake lever 3 and brake member 6 match, the brake hub 16 on the brake member 6 contact castors.
