The utility model has the advantages of compact structure, reasonable design and convenient and quick detection. The pressure is uniform when the utility model is adopted for detecting membrane plates, and the utility model is difficult to damage and has long service life. The produced detecting membrane and warhead rifling traces are clear and stable.

Description

The bullet rifle mark flattening device

Technical field

The utility model belongs to pick-up unit, especially relates to the cartridge mark pick-up unit in a kind of judicial material evidence evaluation field.

Background technology

At present, public security department uses the bullet rifle mark flattening device, form by a heavy sheet glass and a hardwood plate, to make diaphragm during operation places above the glass plate, again bullet is horizontally placed on the rear side of system diaphragm, with hand plank is pushed down bullet and push away forward, the whole coining of rifling vestige on the bullet are being made on the diaphragm, yet, the above-mentioned practice, exist 2 deficiencies, one, the application of force is irregular when pushing away bullet, influence the molding quality, its two, pushing away diving board is wooden structures, the long-term use and repeatedly rub back distortion or damage of bullet.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation, reasonable in design is provided, and the bullet rifle mark of making is clear, stable.

In order to achieve the above object, the technical solution adopted in the utility model is: the support upper surface is provided with seat top plate, mounting bracket on it, the middle part has eccentric wheel to be installed on the turning axle in the support, turning axle one end is installed the knob of transferring the files, the cantilever tip position has groove, be provided with in the groove and push away diving board, push away the side's of having handrail on the diving board, push away the diving board lower end and be inlaid with the rolling sheet, before rear and front end, seat top plate upper surface is equipped with, back plate washer, the position, upper end is equipped with U type backing plate between the plate washer of front and back, and its lower end part two ends have spring groove, there is long spiro nail both sides, seat top plate lower end, be set with spring on it and backing plate joins, there is crossbeam the eccentric wheel below, and screw is installed in the backing plate lower end part in which is provided with.

The utility model has the advantages that:

Compact conformation, reasonable in design, easy to detect, quick, it is even, not fragile to adopt this device to detect lamina membranacea pressure, long service life, detection diaphragm, the bullet rifle mark of making is clear, stable.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 3 as can be known, the utility model is that support 13 upper surfaces are provided with seat top plate 4, mounting bracket 8 on it, the middle part has eccentric wheel 16 to be installed on the turning axle 12 in the support 8, turning axle 12 1 ends are installed the knob 11 of transferring the files, position, support 8 top has groove, be provided with in the groove and push away diving board 15, push away the side's of having handrail 1 on the diving board 15, push away diving board 15 lower ends and be inlaid with rolling sheet 14, before rear and front end, seat top plate 4 upper surface is equipped with,

back plate washer

7,17, front and back plate washer 7, the position, upper end is equipped with U type backing plate 6 between 17, and its lower end part two ends have spring groove 5, there is long spiro nail 18 both sides, seat top plate 4 lower end, be set with spring 10 on it and join with backing plate 6, there is crossbeam 20 eccentric wheel 16 belows, and screw 19 is installed in backing plate 6 lower end parts in which is provided with.

Position, support 8 rear end is installed and is decided elastic rod sheet 3.

Position, front apron 7 upper end is equipped with to connect and plays groove 9

Deciding position, elastic rod sheet 3 rear end is equipped with and decides bullet handle 2

During with the rifling vestige diaphragm on " bullet rifle mark flattening device " making shooting warhead, to make diaphragm earlier as on the backing plate, again bullet is placed the rear side of system diaphragm, fix with deciding the elastic rod sheet, holding the knob of transferring the files then rotates forward, at this moment, eccentric wheel boss on the turning axle begins to lean crossbeam, decontrol when making backing plate drop to minimum point, after the front end that pushes away diving board is pushed into bullet top, the knob of will transferring the files again back rotates, at this moment, eccentric wheel planar portions on the turning axle causes the body of bullet and the rolling sheet that pushes away the diving board bottom to be adjacent to for leaning crossbeam again, holds handrail and is pushed into bullet forward and falls into to connect and play in the groove, the bullet rifle mark diaphragm of making can be extracted check from backing plate.
