Description

Technical Field

[0001] The utility model belongs to the technical field of nail-shooting fastening, and in particular relates to a combined spring-nail integrated nail. Background Art

[0002] Gunpowder nail fastening equipment includes three series of products: nail bullets, nail guns and nails. The basic principle is to use a nail gun to hit the bottom of the nail bullet to ignite the propellant inside the nail bullet, thereby generating a strong driving force to drive the nail into the matrix, thereby achieving the purpose of fixing the nail. Because of its advantages such as easy use and good fastening effect, it is widely used in construction, decoration, smelting and chemical industry, underwater operations and other fields.

[0003] The bullet-nail integrated nail specifically refers to a nail and bullet as an integral structure. At present, the shell and nail body of the bullet-nail integrated nail are integrally formed by injection molding. However, this type of product has the following problems during production and use:

[0004] First, it is easy to explode during use and the power is unstable;

[0005] Second, for R&D and manufacturing, different types of nails require different injection molds, which increases production costs and makes the process complicated.

[0006] In order to reduce the investment in molds, the traditional integrated nails are structurally improved. Figure 1 , 2 As shown, the integrated nail comprises a coaxially arranged cartridge case 1 and a nail 2; the cartridge case 1 is provided with an inner cavity which is coaxially arranged with itself and has an opening at one end, the end of the cartridge case 1 opposite to the opening is a firing end, and a firing portion 103 is provided in the middle of the end face of the firing end; the nail 2 comprises a nail body 201, one end of the nail body 201 is provided with a connector 202, and the other end is provided with a tip portion 203; the inner cavity comprises a charging section 109 and a connecting section 1010 arranged along the axial direction L of the cartridge case 1, and the connecting section 1010 is arranged adjacent to the opening of the inner cavity; the connecting head 202 extends into the connecting section 1010 and cooperates with each other, so that the connecting head 202 is connected to the cartridge case 1 and blocks the opening of the inner cavity; the end face of the connecting head 202 away from the nail body 201 and the charging section 109 form a charge chamber, and the charge chamber is filled with propellant 3. By standardizing the connector 202 and the connecting section 1010, different types of nails and cartridges can be used interchangeably, which is beneficial to saving R&D and mold opening costs. However, since the propellant is in direct contact with the connector of the nail, which is made of metal, the propellant has a certain corrosive effect on the connector of the nail, which may affect the normal use of the nail over time.

DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] A combined bullet-nail integrated nail comprises a cartridge case 1 and a nail 2 which are coaxially arranged; one axial end of the cartridge case 1 is a firing end 101, and the other end is a connecting end 102; the cartridge case 1 comprises a charge barrel 104 which is open at one end, and a cover body 105 is sealed on the open end of the charge barrel 104 to form a charge chamber, and the charge chamber is filled with propellant 3; a firing part 103 is arranged on the cover body 105, and the firing part 103 is located in the middle of the end surface of the firing end 101; the nail 2 comprises a nail body 201 which is coaxially arranged with the cartridge case 1, a connecting head 202 is arranged at one end of the nail body 201, and a tip part 203 is arranged at the other end; the connecting head 202 is connected to the charge barrel 104 by a connecting structure, and is arranged adjacent to the connecting end 102.

[0035] Specifically, the cartridge case 1 is a cylindrical structure, and the charge barrel 104 is coaxially arranged with the nail body 201. The cover 105 serves to block the opening of the charge barrel 104, and the propellant 3 is loaded in the charge chamber surrounded by the charge barrel 104 and the cover 105 to prevent the propellant 3 from getting wet. When in use, the integrated nail is placed into the launch tube of the nail gun, and the nail gun fires the firing pin. The firing pin penetrates the firing part 103 and then is inserted into the propellant 3. The entry of the firing pin produces extrusion and high friction on the propellant 3. The sensitivity of the frictional temperature rise is used to make the propellant 3 explode in the confined space, and the generated gas is ejected in the direction from the firing part 103 to the tip 203, so that the cover 105 is separated from the charge barrel 104. The charge barrel 104 rushes out of the launch tube along with the nail 2 in the direction from the firing part 103 to the tip 203, completing a nail tightening operation, and finally removing the charge barrel 104 from the nail 2. Compared with the integrated nail in the background technology, the direct contact between the propellant 3 and the nail 2 can be avoided, and the corrosion of the propellant 3 on the connector 202 of the nail 2 can be effectively avoided. When the projectile fails, the projectile is replaced; when the nail fails, the nail is replaced. It is also beneficial to saving materials and avoiding the overall scrapping of the spring-nail integrated nails.
