CN202024688U - Starting cartridge - Google Patents

Abstract

The utility model discloses a starting cartridge, which comprises a cartridge case, a primer mixture layer, a smoking agent layer and a sealing paper washer layer, wherein the bottom thickness of the cartridge case is 0.3-0.5mm; the primer mixture layer is paved at the bottom of an inner cavity of the cartridge case; the smoking agent layer is paved on the primer mixture layer; and the sealing paper washer layer is arranged on the smoking agent layer. According to the starting cartridge, the bottom thickness of the cartridge case for directly influencing the reliability of products is designed to be 0.3-0.5mm. The phenomena that the far-thinner bottom is broken through by a firing pin of a starting device, so that smoke leaks or even the starting device is damaged and injures users are thoroughly avoided. Meanwhile, the phenomenon the misfire is often generated because the bottom is far thicker and the firing can be realized by greater firing power is avoided, and the reliability of the starting cartridge is improved.

Description

A kind of blank cartridge

Technical field

The utility model relates to track and field events signal starting installation technical field, the high blank cartridge of particularly a kind of reliability.

Background technology

Blank cartridge is for starting pistol percussion, can produce the sound or have the bullet of white smoke signal concurrently.Different with center fire army, police gun bullet, blank cartridge does not have the special fire in a stove before fuel is added, be to form fiery platform by the shell case root edge, the primer mixture root edge slit of packing into, controller percussion shell case root edge relevant position is got angry primer mixture, light smoke agent, smoke agent acutely burns, and produces the sound and smog, issuing an order when being mainly used in track and field events and training, timing.

Yet, owing to blank cartridge housing bottom thickness problem, often occur being punctured by the controller firing pin, produce and leak cigarette, even controller damage and injury user of service occur, the misfire phenomenon perhaps appears.Therefore, need the higher blank cartridge of a kind of reliability at present badly.

The utility model content

In view of this, the utility model provides a kind of blank cartridge, to improve its reliability.

For achieving the above object, the utility model provides following technical scheme:

A kind of blank cartridge comprises:

Shell case, its bottom thickness are 0.3-0.5mm;

Be laid on the primer mixture layer of the intracavity bottom of described shell case;

Be laid on the smoke agent layer on the described primer mixture layer;

Be arranged on the sealed paper bed course on the described smoke agent layer.

Preferably, in above-mentioned blank cartridge, the length of described shell case is 12～15mm.

From above-mentioned technical scheme as can be seen, the utility model is 0.3-0.5mm by the cartridge case base Thickness Design that will directly influence product reliability.Thoroughly avoided being punctured by the controller firing pin easily, produced and leak cigarette, even controller damage and injury user of service phenomenon have occurred because the bottom is too thin.Also avoided simultaneously needing bigger percussion strength could get angry, and the misfire phenomenon of frequent appearance, improved the reliability of blank cartridge because the bottom is too thick.

The specific embodiment

The utility model discloses a kind of blank cartridge, to improve its reliability.

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

See also Fig. 1, the structural representation of the blank cartridge that Fig. 1 provides for the utility model embodiment.

The blank cartridge that the utility model provides comprises shell case 1, primer mixture layer 2, smoke agent layer 3 and sealed paper bed course 4.Wherein shell case 1, its bottom thickness is 0.3-0.5mm, and primer mixture layer 2 is laid on the intracavity bottom of described shell case 1, and smoke agent layer 3 is laid on the described primer mixture layer 2, sealed paper bed course 4 is arranged on the described smoke agent layer 3, and the top of shell case 1 is the closing in structure 5 of taper.The length of shell case 1 can be 12～15mm.

The utility model is 0.3-0.5mm by the cartridge case base Thickness Design that will directly influence product reliability.Thoroughly avoided being punctured by the controller firing pin easily, produced and leak cigarette, even controller damage and injury user of service phenomenon have occurred because the bottom is too thin.Also avoided simultaneously needing bigger percussion strength could get angry, and the misfire phenomenon of frequent appearance, improved the reliability of blank cartridge because the bottom is too thick.

Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
