Abstract
The invention discloses a single hinge type staggered joint short strong-force hand cutting device, relates to a hand tool product capable of quickly shear steel bars, cables, steel wire ropes and other metal wires in a narrow space to salve buried people and protect material assets in the emergency rescue process when buildings collapse due to earthquakes, fires and other disasters, and belongs to the field of hardware tool product manufacture. The device comprises an upper blade and a lower blade; one end of the upper blade and one end of the lower blade are connected through a pin roll; two jaws can rotate, separate and close around the pin roll; the other end of the upper blade and the other end of the lower blade are connected through high strength screw and nut; and a person rotates the screw and the nut through a wrench to control the separating and closing angle of the jaws and apply the shear force to a material to be sheared to fulfill the shearing aim. The device is small in volume, and can magnify the operating force of a human body by tens of times and even hundreds of times to apply the magnified force to the material to be sheared by a screw force-boosting mechanism and a lever principle so as to realize strong-force shear.
Description
Technical field
The present invention is a kind of when being used for disasters such as earthquake, fire and causing building collapsing; In the emergency relief process; For personnel and goods and materials are buried in relief, can be in small space the hand-held tool product of metal wire rods such as shear reinforcement, cable, steel wire rope rapidly, belong to the manufacturing field of hardware & tools product.
Background technology
When disasters such as generation earthquake, fire; Often cause building collapsing; In implementing the emergency relief process; Covered the personnel and the goods and materials of reason for relief; Need be in small space metal wire rods such as shear reinforcement, cable, steel wire rope; Under the situation of outage, these metal objects of THE ADIABATIC SHEAR IN will try to gain time precious to one for rescue.In a period of time after disaster takes place, the scene often cuts off the power supply, and electric tool is not used; Flame, plasma, cut possibly not satisfy the requirements yet; Instrument such as hydraulic tool and bolt clipper is bulky, and handle is very long, in narrow and small working space, can't implement to shear operation; At this moment, just need the little and enough big hand-held tool of shearing force of a kind of volume.
Summary of the invention
Technical problem: in after calamity, rescuing; Usually need be in small space metal wire rods such as shear reinforcement, cable, steel wire rope; Electric tool can't use because of the scene outage; Flame, plasma, cut possibly not satisfy the requirements yet; Hydraulic pressure bolt clipper and hand-power bolt clipper are big because of volume, handle is long; In narrow and small working space, can't implement to shear operation, so need the little and enough big hand-held tool of shearing force of a kind of volume.As why not by electric power and hydraulic machinery, with the strength of rescue personnel's human body, through the little hand-held tool of a volumes; Adopt an appropriate force-increasing mechanism; Produce enough big shearing force, realize these metal wire rods of THE ADIABATIC SHEAR IN, the problem that will solve required for the present invention exactly.
Technical scheme: the present invention adopts spiral force-increasing mechanism and lever principle, adds upper ejector lever as aid, and the operating physical force of human body is amplified to tens of times even hundreds of times, thereby it is small and exquisite and have enough big shearing force to reach structure.The present invention is divided into two blades up and down; One end connects with a bearing pin; Two jaw bodies can be around bearing pin rotation deciliter; The other end is connected with nut with the high strength screw rod that has spheric washer; The people passes through with spanner rotary screw and nut; Can control deciliter angle of jaw body, and to the material that will shear apply shearing force, reach the purpose of cutting off.
Beneficial effect: structure of the present invention is small and exquisite, can in small space, implement shearing manipulation; Need not to rely on power supply, can operate with hand-power fully.Be specially adapted in the disaster; During building collapsing; Be rescue worker and goods and materials under collapsed building; Need cut off the reinforcing bar in the building; The metal wire rod of cable; And can't use electronic, hydraulic pressure, flame cutting equipment the time, the present invention can help the rescue personnel to realize cutting off fast, for rescue attempt tries to gain time precious to one.
Description of drawings
Fig. 1 is a structure diagram of the present invention.
Wherein have with lower component: bearing pin 1, movable blade 2, fixedly blade 3, high-strength screw rod 4, spheric washer 5, nut 6.
The specific embodiment
The present invention adopts spiral force-increasing mechanism and lever principle, adds upper ejector lever as aid, and the operating physical force of human body is amplified to tens of times even hundreds of times, thereby it is small and exquisite and have enough big shearing force to reach structure.Movable blade of the present invention 2, fixedly blade 3 one ends connect through bearing pin 1; Two blades can be around bearing pin rotation deciliter; The other end is connected with nut with the high strength screw rod; The people passes through with spanner rotary screw and nut; Can control deciliter angle of jaw body; And to the material that will shear apply the shearing force of amplification, reach the purpose of cutting off.
Claims (4)
1. an advantages of small volume can realize the powerful hand-held tool of shearing operation, by up and down blade 2, fixedly blade 3, bearing pin 1 and the high-strength bolt 4, the nut 6 that have a spheric washer 5 are formed.Two blades connect with bearing pin, and bearing pin and bolt are separately positioned on the cutting edge both sides, and cutting edge is the mismatch type.
2. the powerful hand parting tool of the short type of single hinge formula mismatch according to claim 1 is characterized in that advantages of small volume, pure hand-power operation, and cutting edge is the mismatch type.
3. the powerful hand parting tool of the short type of single hinge formula mismatch according to claim 1 is characterized in that two blades connect with bearing pin.
4. the powerful hand parting tool of the short type of single hinge formula mismatch according to claim 1, its characteristic is that also packing ring has sphere.
