Abstract

The present invention provides a buffering training bullet. A bullet head is connected with a bullet body provided with an inner hole, and screw threads are arranged at the lower part of an inner hole wall. A bullet rear seat internally provided with a through hole is connected with the lower part of the inner hole of the bullet body through the screw threads. A hollow cavity arranged in the bullet head is correspondingly communicated with the inner hole, and a buffering shaft is respectively arranged in the inner hole and the through hole. The middle part of the buffering shaft is provided with a lug boss contacting the bullet rear seat, and a buffering spring is sheathed on the buffering shaft. The top end comes into contact with the edge at the lower end of the bullet head, and the bottom end comes into contact with the lug boss. The present invention can solve the problems that in the prior art, a real bomb loading and unloading training effect does not exist, the service life is shorter, and a driving hammer in a gun is easily damaged.

Description

Buffer training bullet

Technical field:

The present invention relates to military training bullet technical field.

Background technology:

When being engaged in military teaching and training, often to carry out the firing item training to the student.At present, when gunnery training,, mostly take following two kinds of forms to carry out for saving live shell: one, dry practice shooting form, it not only exists can't practise loading and unloading the bullet essential of exercise, but also has the problem of damaging hammer in the gun easily; Two, with empty medicine dummy round exercise shooting form, because of empty medicine dummy round own wt lighter, it exists no live shell loading and unloading training effect and service life than short shortcoming, and the fire in a stove before fuel is added of empty medicine dummy round substitutes with rubber blanket, because of rubber blanket is broken up brokenly easily by the firing pin in the gun, be the hammer that damages easily in the gun equally with the consequence that this was caused.

Summary of the invention:

The invention provides a kind of buffer training bullet, the no live shell that it can solve the prior art existence loads and unloads the problem of training effect, service life lacking, damaging hammer in the gun easily.

The present invention is achieved by the following technical solutions: buffer training bullet, bullet is connected with bomb body, and bomb body has endoporus, and the inner hole wall bottom is provided with screw thread, in establish through hole the bullet back seat be threaded mutually by the bottom of its screw thread with the bomb body endoporus, be arranged on communicate corresponding of cavity in the bullet with endoporus; Buffer shaft is installed in respectively in endoporus and the through hole, and the middle part of buffer shaft is provided with boss, and boss contacts with the bullet back seat; Buffer spring is sleeved on the buffer shaft, and its top contacts with edge, bullet lower end, its bottom contacts with boss.

For further realizing purpose of the present invention, also can take following technical scheme to be finished: to play back seat and be connected with bomb body, the inner hole wall top of bomb body is provided with screw thread, and the bottom of bullet connects column, and column is threaded mutually by the top of its screw thread with the bomb body endoporus; The top of buffer shaft is provided with boss, and boss is installed in the endoporus inner bottom part, and buffer shaft is installed in the through hole; Buffer spring is installed in the endoporus of bomb body, and its top contacts with column, and its bottom contacts with the bullet back seat.Playing the back seat bottom has boss, its with the bomb body bottom between formation grab the bullet groove.The buffer shaft upper end is provided with lacing hole.Buffer shaft is installed in respectively in cavity, endoporus and the through hole.Bomb body respectively with bullet with play back seat and be connected after, its outer shape is identical with the outer shape of 51 formula bullets.Bomb body respectively with bullet with play back seat and be connected after, its outer shape is identical with the outer shape of 64 formula bullets.

The beneficial effect that the present invention can produce: because of buffer shaft and buffer spring are installed in the endoporus of bomb body, and the lower end of buffer shaft is installed in the through hole that plays back seat, when the training of loading and unloading bullet, it can simulate the live shell training; When gunnery training, the firing pin collision buffering axle in the gun, buffer shaft is displacement forward then, and its impact is cushioned spring buffer, and it can not damage the hammer in the gun with this, and its weight is similar to live shell, and it can reach the simulated training effect; Because of the wall of bomb body, bullet and bullet back seat is thicker, connected mode is unique each other, so service life is longer.

Description of drawings:

Fig. 1 is be threaded the mutually structural representation of form of bomb body of the present invention 4 bottoms and bullet back seat 7;

Fig. 2 is be threaded the mutually structural representation of form of bomb body of the present invention 4 tops and bullet 1.

The specific embodiment:

Buffer training bullet of the present invention, bullet 1 is connected with bomb body 4, and bomb body 4 has endoporus 11, and endoporus 11 wall bottoms are provided with screw thread, in establish through hole 10 bullet back seat 7 be threaded mutually by the bottom of its screw thread with bomb body 4 endoporus 11, be arranged on cavity 2 and endoporus 11 corresponding communicating in the bullet 1; Buffer shaft 5 is installed in respectively in endoporus 11 and the through hole 10, and the middle part of buffer shaft 5 is provided with boss 5a, and boss 5a contacts with bullet back seat 7; Buffer spring 6 is sleeved on the buffer shaft 5, and its top contacts with edge, bullet 1 lower end, its bottom contacts with boss 5a.Play back seat 7 and be connected with bomb body 4, the endoporus 11 wall tops of bomb body 4 are provided with screw thread, and the bottom of bullet 1 connects column 1a, and column 1a is threaded mutually by the top of its screw thread with bomb body 4 endoporus 11; The top of buffer shaft 5 is provided with boss 5a, and boss 5a is installed in endoporus 11 inner bottom parts, and buffer shaft 5 is installed in the through hole 10; Buffer spring 6 is installed in the endoporus 11 of bomb body 4, and its top contacts with column 1a, and its bottom contacts with bullet back seat 7.Playing back seat 7 bottoms has boss 9, its with bomb body 4 bottoms between form and grab bullet groove 8.Buffer shaft 5 upper ends are provided with lacing hole 3.Buffer shaft 5 is installed in respectively in cavity 2, endoporus 11 and the through hole 10.Bomb body 4 respectively with bullet 1 with play back seat 7 and be connected after, its outer shape is identical with the outer shape of 51 formula bullets.Bomb body 4 respectively with bullet 1 with play back seat 7 and be connected after, its outer shape is identical with the outer shape of 64 formula bullets.

During making, process various parts assemblings by above-mentioned requirements and get final product.During use, pull the trigger of gun, firing pin is collision buffering axle 5 under the effect of hammer, 5 displacements forward of buffer shaft, bomb body 4 bottoms with play be threaded mutually buffer shaft 5 front ends of form of back seat 7 and then be displaced in the cavity 2, buffer shaft 5 with the impact buffering of firing pin, has been avoided its damage to hammer in the gun with this under the effect of buffer spring 6.Buffer shaft 5 is inverted installs, 3 of its lacing holes expose and play outside the back seat 7, the present invention can be hung on the person or the object penetrating cord on the lacing hole 3.

The technology that the present invention does not describe in detail partly is known technology.
