DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] Please refer to Figures 1 to 4 , an integrated nail is provided in an embodiment of the present application, which includes a nail body 1, a gasket 2 and a threaded sleeve 4. The nail body 1 includes a tip portion 11, a rod portion 12 and a nail head portion 13. The diameter of the nail head portion 13 is greater than that of the rod portion 12. An opening 21 for the tip portion 11 and the rod portion 12 to pass through is provided on the gasket 2. A percussion charge assembly 3 is installed on the nail head portion 13;

[0023] The percussion charge assembly 3 includes a projectile body 31 and a cartridge case 32. A first cavity 311 and a second cavity 312 are provided in the projectile body 31. The nail head portion 13 is installed in the first cavity 311. The cartridge case 32 is press - fit and inserted into the second cavity 312. The outer wall of the cartridge case 32 is in contact and cooperation with the inner wall of the second cavity 312. A primer 33 and a propellant 34 are installed in the cartridge case 32. The primer 33 and the propellant 34 are arranged in sequence, and the primer 33 is close to the inner wall of the top end of the cartridge case 32. Both the projectile body 31 and the cartridge case 32 are made of plastic, preferably integrally injection - molded with ABS plastic;

[0024] The outer wall of the threaded sleeve 4 is provided with an external thread. The threaded sleeve 4 is fixedly connected to the gasket 2. The threaded sleeve 4 and the gasket 2 are coaxially arranged. The threaded sleeve 4 is sleeved on the rod portion 12 and is slidably connected to the rod portion 12. By providing the threaded sleeve 4, it can not only realize the guiding of the rod portion 12, facilitate the nail body 1 to be directly inserted into the installation matrix, improve the installation stability, but also facilitate the installation of the installation device on the threaded sleeve 4.

[0025] The nail head portion 13 is press - fit and installed in the first cavity 311. In this way, it can not only realize the connection with the percussion charge assembly 3, but also facilitate the separation of the projectile body 31 and the nail head portion 13 after the percussion charge assembly 3 is fired.

[0026] The diameter of the nail head 13 is smaller than the outer diameter of the threaded sleeve 4; a transition portion 14 is provided at the connection between the rod body portion 12 and the nail head 13, and the transition portion 14 is an arc transition structure. A receiving groove 41 for receiving the transition portion 14 is provided at one end of the threaded sleeve 4 facing away from the gasket 2. The provision of the transition portion 14 can improve the overall strength and service life of the nail body 1. By providing a chamfer at one end of the inner cavity of the threaded sleeve 4 away from the gasket 2, the receiving groove 41 is formed; the provision of the receiving groove 41 enables the transition portion 14 to enter the receiving groove 41 when the nail body 1 is inserted into the mounting base after being fired by the primer assembly 3, avoiding contact between the transition portion 14 and the threaded sleeve 4 and preventing the threaded sleeve 4 from being subjected to the radial force caused by the impact of the transition portion 14; in this way, the bottom wall of the nail head 13 can contact the threaded sleeve 4, increasing the contact area between the nail body 1 and the threaded sleeve 4.

[0027] One end of the gasket 2 facing the threaded sleeve 4 is convex. After the nail body 1 is shot into the base, the convex portion of the gasket 2 will deform, which can play a buffering role.

[0028] One end of the cartridge case 32 is open and the other end is closed. A piercing blind hole 321 is provided at the center of the closed end of the cartridge case 32; this can reduce the thickness at the center of the rear end of the cartridge case 32, and when firing, the firing pin of the nail gun can more easily enter the piercing blind hole 321 and pierce the cartridge case 32.

[0029] A positioning ring groove 313 is provided on the bottom wall of the second cavity 312. The open end of the cartridge case 32 is inserted into the positioning ring groove 313, and the inner wall of the cartridge case 32 is in contact and cooperation with the inner wall of the positioning ring groove 313. The cartridge case 32 is press-fitted into the second cavity 312, which can enhance the fixing effect of the projectile 31 on the cartridge case 32.

[0030] During use, the entire integrated nail is loaded into the nail gun. The gasket 2 is attached to the plane of the mounting base. Since the threaded sleeve 4 is fixedly connected to the gasket 2, after the gasket 2 is attached to the plane of the mounting base, the threaded sleeve 4 will be perpendicular to the mounting base. Since the threaded sleeve 4 is slidably connected to the rod body portion 12, it can realize the guiding of the nail body 1 and the positioning of the installation angle of the integrated nail;

[0031] The piercing blind hole 321 is pierced by the firing pin of the nail gun. The primer 33 is struck and ignites the propellant 34. The high-temperature and high-pressure gas generated by the combustion of the propellant 34 causes the projectile 31 and the nail body 1 to rush out. The pointed end portion 11 and the rod body portion 12 are driven into the base body. After the top head contacts the threaded sleeve 4, the position of the nail body 1 is fixed, completing the installation of the integrated nail; since the nail head 13 is press-fitted into the first cavity 311, it is convenient to separate the projectile 31 from the nail head 13;

[0032] Subsequently, the installation device can be installed on the threaded sleeve 4, and then a nut can be installed on the threaded sleeve 4 to fix the installation device.

[0033] It should be noted that, for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
