Description

Bullet is disassembled device

Technical field

The utility model relates to alert using and the military equipment field, especially relates to the device of disassembling bullet.

Background technology

For the destruction of the processing of duds, expired bullet, the occasions such as ammunition evidence obtaining research of scene of a crime, all need bullet is disassembled, bullet is separated with shell case, take out the inner gunpowder of bullet then, gunpowder is carried out weighing and analysis.Utility model 200520083705 discloses a kind of bullet decomposer, comprise frame, leading screw, bullet fixed mount and play the back seat fixed mount that lead screw hole and shothole are arranged on the frame, and leading screw interts in lead screw hole, be provided with nut on the end of leading screw outside frame, the other end is connected with the bullet fixed mount.This disassembling apparatus has solved the safe problem of disassembling bullet, but the apparatus structure complexity is used loaded down with trivial details.

The utility model content

The applicant at above-mentioned bullet decomposer complex structure, use shortcomings such as loaded down with trivial details, provide a kind of simple in structure, easy to operate bullet is disassembled device, can convenient and safely disassemble bullet fast.

The technical scheme that the utility model adopted is as follows:

A kind of bullet is disassembled device, comprise head and shank, described head comprises the tube column of end sealing, one end butt of the openend of described tube column and a bullet chuck, the internal diameter of tube column openend is greater than the external diameter of disassembling bullet bullet and less than the external diameter of described bullet chuck, end cap entangle behind the described bullet chuck with the tube column openend with being threaded, with bullet chuck axial compression between the inner face of described tube column openend and end cap.

Bullet is disassembled device, and the inner face of the blind end of described tube column is provided with axial ribs.

Bullet is disassembled device, the annular solid of described bullet chuck for constituting by the amalgamation of a plurality of arc body fixture block, the diameter of annular solid annular distance matches with the external diameter of disassembling bullet shell case, the inner ring surface of annular solid has the flange with described shell case groove tabling, the outer ring surface of annular solid is provided with annular groove, device spring in the annular groove.

Bullet is disassembled device, the annular solid that described bullet chuck constitutes for the arc body fixture block amalgamation by 3 120 ° of arcs.

Adopt the utility model to carry out disassembling of bullet, fast convenient and safety, and can not trickle down gunpowder, the analysis result of influence check.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1, bullet described in the utility model is disassembled device and is similar to hammer, is divided into head, shank 8 and grip part 9; As Fig. 2, shown in Figure 3, head comprises main body 1, spiral cover 7, bullet chuck 4 and spring 5.Main body 1 adopts translucency plastic material to make, and is the tube column of a single-ended sealing, and the internal diameter of described tube column is greater than the external diameter of bullet, and the blind end inside of tube column is provided with four triangle muscle 11, and openend is provided with external screw thread 2; Spiral cover 7 is provided with the internal thread 6 that matches with external screw thread 2 at lid oral-lateral inner peripheral surface; Bullet chuck 4 is made up of three identical fixture blocks 14, and each fixture block 14 is the cylinder ring structure of 120 ° of arcs, and the arc body of 120 ° of arcs has best amalgamation power structure, and bullet is installed and removed also most convenient.As shown in Figure 5, side at fixture block 14 inner ring surfaces has the flange 12 that protrudes to the center of circle, be provided with groove 13 at the outer ring surface middle part, ring spring 5 places the outer ring surface groove 13 of three fixture blocks 14, three fixture blocks are combined into an annular chuck 4, the interior ring size of this annular chuck 4 is close with the external diameter of bullet 3, and outer ring size is greater than the diameter of the cavity of main body 1, and less than the lid mouth internal diameter of spiral cover 7.

When reality is used, as shown in Figure 4, at first bullet 3 is filled in the interior ring of bullet chuck 4, the groove 10 that an annular is arranged at the afterbody of bullet, and the interior side ring of chuck 4 has the flange 12 of protrusion, flange 12 snaps in the groove 10 of bullet, and utilizes three fixture blocks 14 of elastic contractile force banding of ring spring 5, can make bullet 3 at axial limiting.Because chuck 4 is arranged to three independently fixture block 14 structures, so chuck 4 goes for the bullet of the close plurality of specifications of external diameter.Bullet 3 front ends are put into the cavity of main body 1, because bullet chuck 4 external diameters are greater than cavity diameter, so chuck 4 is stayed main body 1 outside; Again bullet chuck 4 is inserted in locking spiral cover 7,, locks spiral cover 7 thus, and, eliminate its axial displacement inner bullet chuck 4 axial compression with locking the external screw thread 2 of the internal thread 6 screw-in main bodys 1 of spiral cover 7.

Rap at desktop or ground the sealing of head is distolateral the hand-held grip part 9 of operating personnel's this moment, because the making material of main body 1 is translucent, therefore can observe inner case; Because the effect of inertia of the bullet of bullet, after knocking for several times, the bullet of bullet 3 separates with shell case, and bullet drops on main body 1 cavity front end and blocked by inner triangle muscle 11; And the gunpowder of bullet inside also falls into the cavity front end and drop between the slit between the triangle muscle 11.Because bullet blocked the position that is retained in than the middle part by the triangle muscle, and gunpowder is retained between the slit of triangle muscle, has therefore avoided the collision of gunpowder and bullet and the danger that causes exploding.Operating personnel outward winding spiral cover 7 again, take out bullet chuck 4, and clip bullet shell case in chuck 4 inside this moment, and trip spring 5 can take out shell case; Bullet and gunpowder are poured out from the cavity of main body 1, can be guaranteed can not cause the unrestrained of gunpowder, the analysis result of influence check.

More than describing is to explanation of the present utility model, it or not qualification to utility model, the utility model institute restricted portion is referring to claim, under the situation of spirit of the present utility model, the utility model can be done any type of modification, for example the triangle muscle is set to a plurality ofly, and perhaps the bullet chuck is divided into a plurality of fixture blocks, perhaps changes the shape of shank and grip part.
