Description

Integrated nail cartridge case

Technical Field

The invention relates to the technical field of shooting nails, in particular to an integrated nail cartridge case.

Background

The nail shooter is a modern nail shooting fastening technology product, and belongs to a direct consolidation technology. The nail shooter triggers the nail shooting bullet to generate explosive force to shoot the nail, and the nail shooter directly drives the nail into the matrixes such as steel, concrete, brick masonry or rock, and firmly connects the components needing to be fixed, such as doors and windows, heat insulation boards, sound insulation layers, decorations, pipelines, steel pieces, wood products and the like, with the matrixes, so that the nail shooter is a necessary manual tool for woodworking, building construction and the like.

The existing integrated nail generally comprises a nail shooting bullet and a nail shooting bullet which is injected on the nail shooting bullet. The nail shooting bullet mainly comprises a bullet seat, a medicine cylinder and a power tablet, wherein the power tablet is arranged in the medicine cylinder, and the medicine cylinder is fixed in a bullet hole formed in the bullet seat. The integrative nail just can directly be with penetrating the nail and hit into the base member through detonating the ail shooter during the use for the fixed of component is simple and convenient more, therefore is used more and more extensively.

At present, various improvements have been proposed for the integral nail because the integral nail is more and more important in various industries. The novel plastic shell nail shooting bomb is disclosed as the document with the publication number of CN205166857U, in the document, a propellant powder hole for containing propellant powder and a percussion powder hole for containing percussion powder are arranged in a propellant powder cabin body, a plurality of reinforcing ribs are arranged on the circumferential direction of the inner wall of the percussion powder hole, the effect of strengthening the percussion powder of the nail shooting bomb can be achieved through the reinforcing ribs, the reinforcing ribs can be uniformly distributed, the percussion powder is formed into a plurality of equal parts, and therefore the percussion powder is firm and reliable. However, in the practical application process, the firing powder of the nail shooting bullet with the structure is fully distributed in the firing powder hole, and the firing shape is uniformly divided into a plurality of equal parts by the reinforcing ribs, so that no gap exists in the firing powder hole. When the firing pin punctures the firing concave hole and enters the explosive charging cabin body, under the drive of high-speed friction force and impact force, partial plastic residues at the edge of the firing concave hole are brought into the primer mixture, so that the primer mixture is loosened and raised, and further the friction force between the firing pin and the primer mixture is reduced, and the detonation failure is caused. Meanwhile, the plastic residues can be blocked between the firing pin and the primer, and the detonation of the nail shooting pill is hindered. Furthermore, the applicant adopts the nail shooter to carry out shooting test on the integrated nail formed by the nail shooting ball with the structure, and counts the firing rate of the integrated nail. 10000 shots of practical tests show that the number of detonation failures is 500-1000 shots, the failure rate is 5% -10%, and 5% -10% of dumb bullets exist. Therefore, there is a need for improvement thereof.

Disclosure of Invention

The invention aims to overcome the problems in the prior art and provides an integrated nail cartridge, and the technical problem to be solved is to form an avoiding space for plastic residues so as to reduce the probability of occurrence of a dead bullet.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

the utility model provides an integrative nail cartridge case, includes barrel and nitrocotton tablet, and the barrel includes the inner chamber, hits the end and open end, and the nitrocotton tablet sets up in the inner chamber through the open end, its characterized in that: an avoidance groove is formed in the bottom of the inner cavity, limiting ribs protruding out of the side wall of the avoidance groove are uniformly distributed in the avoidance groove, and an avoidance space for avoiding plastic residues is formed between the limiting ribs; the nitrocotton tablet is located between the opening end and the avoiding groove.

The avoidance groove comprises a groove bottom end and a groove opening end communicated with the inner cavity, and the inner diameter of the avoidance groove is gradually increased from the groove bottom end to the groove opening end.

The inner diameter of the notch end is smaller than that of the inner cavity.

The limiting ribs are integrally formed on the side wall of the avoiding groove.

And the middle part of the striking end is provided with a striking groove.

The invention has the advantages that:

1. compared with the prior art, the cartridge is only provided with one nitrocotton tablet, so that the primer is omitted, and the cartridge is simpler in structure. Meanwhile, the nitrocotton tablet is of an integral flaky structure and is positioned between the opening end and the avoiding groove, so that a certain space gap is formed between the nitrocotton tablet and the hitting end through the avoiding groove. When the firing pin penetrates through the firing end and enters the cartridge, the plastic residues are turned over towards the inner cavity and are extruded into the avoiding space. Therefore, plastic residues cannot be brought into the nitrocotton tablets along with the firing pin, the friction force between the firing pin and the nitrocotton tablets is effectively guaranteed, the occurrence of dumb bullets is reduced, and the firing rate and the construction efficiency are correspondingly improved.

2. The invention sets the inner diameter of the avoiding groove from the bottom end of the groove to the end of the notch to be gradually increased, and has the advantages that the volume of the avoiding space is gradually increased, and plastic residues can be effectively extruded into the avoiding space when being fired.

3. The inner diameter of the notch end is smaller than that of the inner cavity, so that the nitrocotton tablets can be prevented from entering the avoiding groove.
