Description

Technical Field

[0001] The utility model relates to the technical field of nail shooting, in particular to a nail for shooting. Background Art

[0002] When the nail shooting cartridge explodes, the energy scatters in all directions. Since it explodes inside the nail tube of the nail shooter, the energy towards the periphery cannot disperse and can only be emitted forward and backward. As a result, for the nail injection molding, the connecting piece must break from the middle, with the rear end remaining in the nail tube of the nail shooter and the front end shooting into the substrate along with the nail. The original injection molded part of the nail is an integral structure, and a very large force is required to break it when the nail shooting cartridge explodes, consuming a high amount of energy. The existing integrated nail injection molded connecting piece contains a circular column (also known as the firing platform) inside, which is used to press the propellant to form a high-density sealed space. However, in actual use, since a closed mating surface is formed between the inner column of the base and the inner wall of the injection molded shell, when the propellant explodes, the inner wall of the injection molded shell and the side of the firing platform will be tightly wrapped, and energy is also required to separate them. The existing integrated nail primer is at the bottom. When the primer is detonated, the propellant explodes forward from the bottom, and the energy release is slow. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a nail for shooting.

[0004] The purpose of the utility model is achieved through the following technical solutions: A nail for shooting, comprising a nail body, a connecting piece, and a propellant. One end of the nail body is connected to the front end of the connecting piece. The tail end of the connecting piece is secondarily injection molded with a shell. A propellant sleeve is arranged inside the shell, and the propellant is arranged inside the propellant sleeve.

[0005] Specifically, the propellant sleeve is a columnar structure with one end open. The bottom of the inner side of the propellant sleeve is provided with a primer, and the propellant is filled inside the propellant sleeve.

[0006] Specifically, a groove is arranged at the bottom of the inner side of the propellant sleeve. A plurality of support ribs are arranged inside the groove. The primer is placed on the support ribs, and the powder-like propellant is filled inside the propellant sleeve to wrap the primer.

[0007] Specifically, a boss is arranged at the tail end of the connecting piece, and the shell is secondarily injection molded and connected to the boss of the connecting piece.

[0008] The utility model has the following advantages:

[0009] 1. The utility model secondarily injection molds a shell at the tail end of the connecting piece and installs the propellant inside the shell, making the secondarily injection molded joint serve as the breaking point, which can greatly reduce the energy consumption required for the connecting piece to disconnect from the shell during explosion;

[0010] 2. In the present utility model, the percussion primer is surrounded by propellant on all sides. At the moment when the percussion primer detonates, the propellant around it can be detonated simultaneously, which can increase the combustion speed of the propellant and the energy of its instantaneous explosion.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0022] The present utility model will be further described below with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following description.

[0023] As Figures 1 to 7 shown, a nail gun includes a nail body 1, a connecting member 2 and a propellant 3. One end of the nail body 1 is connected to the front end of the connecting member 2. The tail end of the connecting member 2 is secondarily injection-molded with a housing 5. A charge sleeve 4 is arranged in the housing 5. The propellant 3 is arranged in the charge sleeve 4. A boss 9 is arranged at the tail end of the connecting member 2. The housing 5 and the boss 9 of the connecting member 2 are secondarily injection-molded and connected together. In this embodiment, the housing 5 is secondarily injection-molded at the tail end of the connecting member 2, and the propellant 3 is installed in the housing, so that the secondarily injection-molded joint serves as a breaking point, and the energy consumption required for the connecting member 2 to disconnect from the housing 5 can be greatly reduced during explosion. In addition, the effect of facilitating the separation of the connecting member 2 from the housing 5 can also be achieved by setting an indentation at the connection between the connecting member 2 and the housing 5. In this embodiment, the firing platform in the prior art is cancelled, and the propellant 3 is pre-pressed in the charge sleeve 4 and then the charge sleeve 4 is pressed into the connecting member, which can reduce the energy of explosion.

[0024] Furthermore, the charge sleeve 4 is a columnar structure with one end open. A percussion primer 6 is arranged at the bottom inside the charge sleeve 4. The propellant 3 is filled in the charge sleeve 4. A groove 7 is arranged at the bottom inside the charge sleeve 4. A plurality of support ribs 8 are arranged in the groove 7. The percussion primer 6 is placed on the support ribs 8. The propellant 3 in powder form is filled in the charge sleeve 4 to wrap the percussion primer 6. In this embodiment, by setting a groove 7 at the bottom of the charge sleeve 4 and arranging support ribs 8 in the groove 7, during loading, the percussion primer 6 is first placed on the support ribs 8 so that it does not fall to the bottom, and then the propellant 3 in powder form is filled in the charge sleeve 4 to wrap the percussion primer 6. Since the percussion primer 6 is surrounded by the propellant 3 on all sides, when the percussion primer 6 is detonated instantaneously, the gunpowder around it can be detonated simultaneously, increasing the burning speed of the gunpowder and the energy of its instantaneous explosion.

[0025] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the above-mentioned technical content, or modify it into an equivalent embodiment with equivalent changes.
