Problems solved by technology

[0003] The problem with long bullets (the length of the shell is generally 15mm) is: powerful, easy to reform
The mouth of the bullet case adopts the closing method, and the inner diameter of the mouth is about 4mm. It is easy to put steel balls, lead pellets and other objects in it. After firing, it has a greater lethality to the human body. Some criminals use it to commit crimes and have an impact on social security.

Embodiment Construction

[0017] The invention discloses a starting ammunition to avoid illegal modification and endanger the society.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] see figure 1 , figure 1 Schematic diagram of the structure of the starting bomb provided by the embodiment of the present invention.

[0020] The starting ammunition provided by the present invention includes: a shell case 1 , a firing charge layer 2 , a smoker layer 3 and a sealing paper cushion layer 4 . Wherein, the opening end of the car...

Abstract

The invention discloses a starting cartridge which comprises a cartridge case, a priming composition layer, a smoke agent layer and a sealed paper pad layer, wherein an opening end thereof is closed in a star shape, and the length of the cartridge case is 8-10 mm; the priming composition layer is paved on an inner cavity bottom of the cartridge case; the smoke agent layer is paved on the priming composition layer; and the sealed paper pad layer is arranged on the smoke agent layer, wherein the sealed paper pad layer is adhered on the cartridge case. Since an opening part is closed in the star shape by substituting the original round shape, the inner diameter of the opening part can be 2 mm less than that of the common starting cartridge so as to effectively prevent the reforming of the starting cartridge caused by loadings such as steel balls and the like. The length of the cartridge case is designed as 8-10 mm, which is only 2 / 3 of the normal starting cartridge; the cartridge case is short so that the volume of the powder chamber is small and the loading dosage of the smoke agent is limited. On the one hand, the illegally changed starting cartridge against society can be prevented; on the other hand, the closed opening is in favor of the full combustion of the smoke agent after the starting cartridge is fired, so that the sound and smog can achieve a regulated index requirement when the volume of the powder chamber is small and the loading dosage of the powder is limited.

Description

technical field [0001] The invention relates to the technical field of signaling equipment for track and field competitions, in particular to a starting bullet capable of avoiding illegal modification and endangering society. Background technique [0002] The starting bullet is used for the firing of the starting gun, which can produce a sound or a bullet with a white smoke signal. Different from the military and police bullets fired in the center, the starting bullet does not have a special primer. It relies on the bottom edge of the shell to form a fire table. Smoker, the smoker burns violently and produces sound and smoke. It is mainly used for starting and timing in track and field competitions and training. [0003] The problem with long bullets (the length of the bullet case is generally 15mm) is that they are powerful and easy to reform. Because the cartridge case is long, the volume of the drug chamber is large, and the charge of the smoke agent is large, it is pow...
