Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nail shooting fastening, and particularly relates to a new type of plastic shell nail shooting bullet. Background Art
[0002] The nail shooting fastening technology uses a nail shooting gun to shoot a nail shooting bullet, so that the gunpowder in the bullet burns and releases energy, and directly nails the nail into a hard base body, such as metal, concrete, rock, masonry, etc. The main tools used in the nail shooting fastening technology are a nail shooting gun, a nail shooting bullet, a nail and some accessories.
[0003] In the prior art, the traditional nail shooting bullet and the nail shooting fastener are often of an integrally formed structure, and the warhead of the nail shooting bullet is directly in contact with the tail of the nail. When the size of the warhead is fixed, one type of warhead cannot be adapted to multiple types of nails. Moreover, the nail shooting speed is relatively fast and the danger is relatively high. At the same time, when the conventional nail shooting bullet is fired, the plastic shell may be broken, resulting in energy loss and a decrease in the penetration ability of the nail.
[0004] Therefore, a new type of plastic shell nail shooting bullet is proposed, which adopts a split design of the nail shooting bullet and the nail shooting fastener. The steel sheet is struck by the nail shooting bullet, and the steel sheet plays a role similar to that of a firing pin, and then the nail is fired, so that multiple types of fasteners can be adapted. At the same time, a harder shell and an explosion guiding structure are provided to avoid excessive loss of explosion energy and ensure the penetration power of the nail. Content of the Utility Model
[0005] In order to overcome the problems that the existing nail shooting bullets are difficult to adapt to multiple types of nail shooting fasteners, and at the same time, the explosion energy of the conventional nail shooting bullets is easily lost, resulting in insufficient penetration power of the nails.
[0006] The technical solution of the utility model is as follows: a new type of plastic shell nail shooting bullet, which includes a protective sleeve; the protective sleeve is a cylindrical structure with open ends at both the front and the rear; a steel sheet for impact is movably arranged on the inner wall at the rear end of the protective sleeve; a moisture-proof rubber sleeve for moisture-proof is movably arranged on the inner wall at the front end of the protective sleeve; the moisture-proof rubber sleeve is a cylindrical structure with an open end at the rear; a nitrocellulose charge for providing energy is movably arranged on the inner wall of the moisture-proof rubber sleeve.
[0007] Preferably, this nail gun cartridge adopts a split design from the nail fastener. By igniting the nail gun cartridge, the steel sheet is struck, and the steel sheet acts like a firing pin. Then the nail is fired, which can be adapted to various types of fasteners. Moreover, when using the steel sheet to strike and fire the nail, the force on the nail is more uniform, ensuring that the nail can move forward in the guiding direction of the barrel. The exit speed is lower, making it safer to use. At the same time, a moisture-proof rubber sleeve and an explosion diversion groove are provided inside the harder polycarbonate protective sleeve. While preventing the nitrocellulose charge from getting wet, it can more precisely control the explosion direction, making the explosion energy more concentratedly released, thereby avoiding excessive loss of energy due to the fragmentation of the outer shell and ensuring the penetration power of the nail.
[0008] Preferably, a first isolation shell is fixedly connected to the rear edge of the inner wall of the protective sleeve; the rear end of the first isolation shell is in contact with the front end of the steel sheet; through the setting of the first isolation shell, it helps to prevent water vapor from invading the inside of the protective sleeve through the gap between the steel sheet and the protective sleeve, avoiding the nitrocellulose charge from getting wet during storage.
[0009] Preferably, a limiting post is fixedly connected to the front end of the first isolation shell; the outer diameter of the limiting post is smaller than the inner diameter of the protective sleeve; the outer wall of the limiting post is in contact with the inner wall of the moisture-proof rubber sleeve; the front end of the limiting post is in contact with the rear end of the nitrocellulose charge; by inserting the moisture-proof rubber sleeve from the front end of the protective sleeve, the inner wall of the moisture-proof rubber sleeve is in contact with the outer wall of the limiting post, playing a role of limiting and fixing, and at the same time improving the overall stability of the structure.
[0010] Preferably, diversion grooves are provided through the front and rear ends of the limiting post; through the setting of the diversion grooves, the direction and release process of the explosion can be more precisely controlled, improving the safety and controllability of the explosion operation. At the same time, the explosion energy can be more concentratedly released, helping to avoid energy loss, ensuring that the nail has sufficient firing energy, and then improving the piercing ability of the nail.
[0011] Preferably, a firing hole is provided through the front end of the moisture-proof rubber sleeve; a second isolation shell is fixedly connected to the rear end surface inside the moisture-proof rubber sleeve; through the setting of the second isolation shell, the airtightness inside the moisture-proof rubber sleeve is ensured, avoiding the nitrocellulose charge from getting wet during storage. Through the firing hole provided through the front end of the moisture-proof rubber sleeve, when the firing pin of the nail gun is fired, the firing pin will pierce through the second isolation shell from the gap of the firing hole, thereby igniting the nitrocellulose charge provided inside the moisture-proof rubber sleeve.
[0012] Preferably, the material of the protective sleeve is polycarbonate; due to the material of the protective sleeve being polycarbonate, polycarbonate has high strength and impact resistance, can withstand the pressure and impact of the high-speed nail gun cartridge during the nailing process, and at the same time maintains sufficient lightweight characteristics, helping to improve the convenience and safety of use.
[0013] Preferably, the moisture-proof rubber sleeve is made of silica gel; the first isolation shell and the second isolation shell are made of low-density polyethylene; since the moisture-proof rubber sleeve is made of silica gel, silica gel has good waterproof performance, softness and elasticity, and can effectively fill and seal the gap between the nitrocellulose charge and the moisture-proof rubber sleeve, thereby effectively preventing moisture and humidity from penetrating into the interior of the moisture-proof rubber sleeve. Since the first isolation shell and the second isolation shell are made of low-density polyethylene, they are softer in texture and easier to be penetrated, and at the same time have good moisture-proof performance and large air permeability, which can ensure that the nitrocellulose charge inside the moisture-proof rubber sleeve remains dry.
[0014] Advantages of the present utility model:
[0015] 1. By using the firing pin of the nail gun to pierce and ignite the nitrocellulose charge inside the nail cartridge, the nitrocellulose charge will explode to generate a large amount of kinetic energy, which will strike and fire the steel sheet at the front end of the nail cartridge. The steel sheet acts like a firing pin and carries the kinetic energy of the explosion to fire the nail again. Through the split design of the nail cartridge and the nail fastener, different sizes and types of nail fasteners can be placed at the front end of the steel sheet, solving the problem that the existing nail cartridges are difficult to adapt to various types of nail fasteners. By adjusting the nitration degree in the nitrocellulose charge, the firing power of the plastic shell nail cartridge can be changed;
[0016] 2. Through the setting of the diversion groove, the direction and release process of the explosion can be more precisely controlled, improving the safety and controllability of the explosion operation. At the same time, the explosion energy can be released more concentratedly, helping to avoid energy loss, ensuring that the nail has sufficient firing energy, and then improving the piercing ability of the nail;
[0017] 3. Since the protective sleeve is made of polycarbonate, polycarbonate has high strength and impact resistance, and can withstand the pressure and impact of the high-speed nail cartridge during the nailing process while maintaining sufficient lightweight characteristics. Since the moisture-proof rubber sleeve is made of silica gel, silica gel has good waterproof performance, softness and elasticity, and can effectively fill and seal the gap between the nitrocellulose charge and the moisture-proof rubber sleeve, thereby effectively preventing moisture and humidity from penetrating into the interior of the moisture-proof rubber sleeve. Since the first isolation shell and the second isolation shell are made of low-density polyethylene, they are softer in texture and easier to be penetrated, and at the same time have good moisture-proof performance and large air permeability, which can ensure that the nitrocellulose charge inside the moisture-proof rubber sleeve remains dry.
