Abstract

The invention provides a pair of barrier breaking pliers, of which the shell is internally provided with a device for shearing a shearing body by manually shaking a screw rod; the shearing device is characterized in that the screw rod is sleeved with an internal-threaded slide block; two sides of the internal-threaded slide block are connected to the internal end of the shearing body by using connecting rods; the tail end of the screw rod is provided with two crank shaft heads capable of being additionally connected with a crank; one crank shaft head is located at one side of the shell tail, and the internal end of the crank shaft head is provided with a bevel pinion meshed with a big bevel gear installed on the screw rod. The barrier breaking pliers make good use of the reciprocal linear slide motion of the screw rod and the stretching motion of the crank, and the variable-speed transmission of the bevel pinion and the big bevel gear, so that the hand-cranking force is amplified for about 90-180 times on the shearing body; in addition, with the smart design of a shearing opening, the barrier breaking pliers can be respectively used for shearing reinforcing steel bars, steel plates and extension openings, are available without power and power supply, light and portable, and capable of being operated by a single person and have multiple use functions.

Description

A kind of broken barrier pincers

Technical field

The present invention relates to the device that uses when a kind of disaster relief and rescue is abolished obstacle, a kind of specifically broken barrier pincers.

Background technology

In various disaster relief and rescue processes such as earthquake, fire, traffic accident, many times all need shear reinforcement, iron sheet, abolish barrier such as door and window, and all there is certain limitation in the various broken barrier instrument that uses at present; Though more large-scale hydraulic pressure is cut its shearing, expansionary force is big; Could use but need to be equipped with power supply power, though small-sized instrument can be sheared, shearing force is little; More do not have expansionary force, can not adapt to actual needs.

Summary of the invention

The objective of the invention is to solve above-mentioned technical deficiency, a kind of broken barrier pincers are provided, but the one man operation has lightweight and portable in volume, does not need any power source and power, but and have an effect of shear reinforcement, steel plate and expansion opening.

The present invention includes brokenly housing, bevel pinion, bevel gear wheel, crank and the pivot pin of barrier pincers; The technical scheme that is adopted is: said broken barrier pincers are equipped with one through realizing the device that spliced body is sheared with hand movable wire thick stick in housing, spliced body is provided with reinforcing bar clip, steel plate clip and extension mouth.

The described shear of such scheme is on leading screw, to be set with an internal thread slide block, and these internal thread slide block branch both sides adopt pivot pin to be connected the inner termination of spliced body through connecting rod.

But be provided with the crank spindle nose of two adjunction cranks at the leading screw tail end, one of them is positioned at housing afterbody one side, and a bevel pinion is equipped with in crank spindle nose the inner of this afterbody one side, the bevel gear wheel adorned on the bevel pinion of adorning and the leading screw mesh together.

But the centre of said housing and afterbody respectively are provided with the fixing threaded hole of a spinning handle.

The present invention passes through technique scheme; Owing to adopted the technical pattern of leading screw rotation driving sliding block and big bevel pinion speed change transmission; Hand power is being amplified on the spliced body about 90～180 times, but the ingenious design of three kinds of effects of shear reinforcement, steel plate and the expansible opening on the spliced body in addition, and it is convenient and swift to make it overall structure; Light, multiple functional; Particularly not needing any power source and power, filled up the vacancy of the special-purpose light instrument of barrier of now providing rescue and relief for disasters and emergencies brokenly, is one of first-selected instrument in the work of providing rescue and relief for disasters and emergencies at present.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description.

Fig. 1 is a structural representation of the present invention.

Fig. 2 is a stereoeffect sketch map of the present invention.

Among the figure: 1, housing, 2, leading screw, 3, the internal thread slide block, 4, connecting rod, 5, spliced body; 6, reinforcing bar clip, 7, the steel plate clip, 8, extension mouth, 9, bevel pinion, 10, bevel gear wheel; 11, crank spindle nose, 12, crank, 13, pivot pin, 14, fixing threaded hole, 15, handle.

The specific embodiment

Shown in accompanying drawing 1,2 embodiment: broken barrier pincers are equipped with one through realizing the device that spliced body 5 is sheared with hand movable wire thick stick 2 in housing 1, spliced body 5 is provided with reinforcing bar clip 6, steel plate clip 7 and extension mouth 8.Shear is on leading screw 2, to be set with an internal thread slide block 3, and 3 fens both sides of this internal thread slide block adopt pivot pin 13 to be connected the inner termination of spliced body 5 through connecting rod 4.But be provided with the crank spindle nose 11 of two adjunction cranks 12 at leading screw 2 tail ends; One of them is positioned at housing 1 afterbody one side; A bevel pinion 9 is equipped with in crank spindle nose 11 the inners of this afterbody one side, the bevel gear wheel 10 adorned on the bevel pinion of adorning 9 and the leading screw 2 mesh together.But the centre of housing 1 and afterbody respectively are provided with the fixing threaded hole 14 of a spinning handle 15.

During practical implementation; The jaw hardness of said spliced body 5 is not less than 55～60HRC; And the jaw material should have stronger quenching degree, and the jaw after the heat treatment should possess outside hard, inner pliable and tough characteristics, and it is good that the jaw material should be selected the tool steel material that contains high Cr for use.
