Embodiment 1

[0017] Such as figure 1 As shown, a screw shock-absorbing nail-shooting device includes a nail-fire combination part and a nail-shooting firing device. The nail-fire combination part includes a steel nail 1, a nail-shooting cartridge 3 and a nail-shooting sleeve 2. The steel nail 1 is located in the groove formed by the nail-shooting cartridge 3 , the nail-shooting cartridge 2 is located outside the nail-shooting cartridge 3 , and the nail-shooting device includes a firing charge located at the lower end of the nail-shooting cartridge 3 . Barrel 14, the nail bullet 4 positioned at the underside of the firing cartridge 14, the screw shock absorber located below the nail bullet 4, and the ejector rod hammer 10 positioned at the bottom of the screw shock absorber.

[0018] In this embodiment, the nail projectile 4 is triggered to move forward by hitting the ejector rod hammer 10, thereby igniting the firing powder in the firing cartridge 14, the firing powder ignites the nail pow...

Embodiment 2

[0021] In order to increase the combustion impact force, the firing cartridge 14 in the first embodiment has a concave-shaped structure, and the side of the firing cartridge 14 is wrapped by the nail cartridge 3 . Setting the firing cartridge 14 in a concave shape can ignite the nail powder in the nail shooting cartridge 3 as quickly as possible, and expand the cross-sectional area of ​​the nail powder column, thereby increasing the impact force during combustion and achieving effective utilization purpose of ammunition.

Embodiment 3

[0023] As a special example of the first embodiment, the screw damping device in the first embodiment includes a primary shock absorbing device and a secondary shock absorbing device, the primary shock absorbing device includes a screw 5 located at the lower end of the nail shooting bullet 4, and the A fixed sleeve 13 is arranged on the outside of the screw 5, an exhaust pipe 6 is arranged below the screw 5, a hollow fixed block 7 is connected to the lower end of the screw, and a shock absorbing spring 12 is connected to the bottom of the fixed block 7, and the fixed The block 7 is rotatably connected with the screw rod 5 , and the secondary damping device includes a liquid storage tank 9 , and the liquid storage tank 9 is connected with the fixed block 7 through a connecting pipe 11 .

[0024] The screw 5 guides the gas to be discharged to the outside through the exhaust pipe 6, and generates the kinetic energy of rotation by itself, consumes the kinetic energy of the gas, and...

Abstract

The invention discloses a screw shock-absorbing nail shooting device, which comprises a nail bomb assembly part and a nail firing device. The nail bomb assembly part includes a steel nail, a nail shooting cartridge and a nail shooting sleeve. The steel nail Located in the groove formed by the nail-shooting cartridge, the nail-shooting cartridge is located outside the nail-shooting cartridge, and the nail-shooting firing device includes a firing cartridge located at the lower end of the nail-shooting cartridge, and a firing cartridge located under the firing cartridge. The nail bullet on the side, the screw damping device under the nail bullet and the ejector hammer at the bottom of the screw damping device. This device converts the kinetic energy of the gas generated in the gunpowder explosion into the kinetic energy of the screw. The screw consumes a lot of energy during rotation, which reduces the impact force of the explosion and compresses the strength of the spring. By guiding the gas to rotate and descend along the screw, it can be offset Due to the partial non-vertical force generated in the explosion, the deviation of the nail shooting device at the moment of nail shooting is greatly reduced, which can effectively protect the safety of workers.

Description

technical field [0001] The invention relates to the field of nail shooters, in particular to a screw shock-absorbing nail shooter. Background technique [0002] Nail fixing technology is a high-efficiency modern fastening technology. Its principle is that the nailer shoots nails and directly drives them into steel, concrete, brick masonry or rocks and other substrates without external energy such as power supply and wind. Pipes, etc., because the nail-shooting bomb itself contains drugs that can produce explosive thrust, and the steel nails are shot directly, so that the components that need to be fixed, such as doors and windows, insulation boards, sound insulation layers, decorations, pipes, steel parts, wood products, etc. and The substrates are firmly connected together. It is precisely because the nail fixing technology is convenient and fast, so it is widely used in construction. [0003] Patent CN205057960U discloses a new type of explosive-driven nail shooting devi...
