Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of striking tools, in particular to an air spring striking tool. Background Art
[0002] There are three main sources of power for nailing tools currently used in China: gas power, which uses lithium batteries to ignite the gas to generate thrust to fix the nails in the concrete; air compressor power; and gunpowder power, which uses the gunpowder in the nail bullet to generate thrust to drive the nails in place.
[0003] However, the existing air spring striking tools are 1. not easy to transport. Gas itself is a consumable material that requires cost. After driving 3,000 nails, a large amount of carbon deposits will adhere to the surface of the cylinder of the nail gun. If it is not cleaned in time, it will cause the nail gun to stop working. It may also ignite the surrounding flammable gas during tunnel construction, which is very dangerous. 2. Although there is no gas carbon deposit on the power source, a bulky air compressor needs to be carried during the construction and tightening process, and a power source needs to be found, which is not convenient for construction in some bridges and tunnels. 3. It is not easy to transport and store. After the gunpowder explodes, a large amount of carbon will also be deposited in the nail gun, which also needs to be cleaned regularly. Construction in some specific areas is very dangerous, such as chemical plants and tunnels. Utility Model Content

The inner wall of the cylinder can be lubricated once for each reciprocating motion. When the piston is compressed to the bottom, the wheel will have a parallel gap and rotate to the specified angle. When the gap of the wheel reaches the angle, the teeth on the firing pin will not be able to engage with the wheel. At this time, the expanding air pressure in the cylinder will push the oil seal and the piston forward. At this time, the nails in the magazine are pushed into the trajectory through the nail pusher assembly. At this time, the firing pin will push the nails forward and drive the nails into the object to be fixed, completing a nailing work. After a nail is driven. An induction magnet is designed under the wheel to sense the position with the stop sensor. When the wheel reaches the specified position, the stop sensor will send a signal to the controller to stop the motor from working, which plays the role of using air compression for nailing and improves practicality.

[0023] The specific problem addressed by this specific embodiment is to solve the problem that gas itself is a consumable material that requires cost, is dangerous, is inconvenient to construct, and is difficult to transport and store. The utility model utilizes the power part of the nail gun as an aluminum alloy cylinder, which is filled with a certain amount of air. During operation, the battery 39 drives the motor 32 to drive the gear box to compress the firing pin 16 backward. At this time, the air in the inner cylinder 10 is compressed and expanded. Then press the switch 36 to release the firing pin 16. At this time, the expanded air pushes the firing pin 16 out to complete the nailing, and the air in the inner cylinder 10 will not leak. It can be used repeatedly without maintenance.
[0024] A striker 16 is provided on one side of the inner cylinder 10 through a shock absorbing block 11, a support ring 18 is fixedly installed on one end of the striker 16 through a piston 17, a piston seal 20 and an oil seal 21 are provided between the piston 17 and the support ring 18, an oil seal 22 is provided on one side of the adjacent groove of the support ring 18, and a gas nozzle 23 is provided on the surface of the outer cylinder 12. In this specific embodiment, a groove is provided on the surface of the gun housing 13, a trigger 35 is provided inside the groove, a switch insurance 34 is provided inside the trigger 35, a switch 36 is provided at the bottom of the switch insurance 34, and a controller 37 and a switch surface are provided inside the gun housing 13.

The inner cylinder 10 and the outer cylinder 12 and the cylinder head 14 and the alloy gun seat 9 form a complete air spring power assembly. A piston seal 20 is designed on the piston 17, which can perfectly seal the air pre-filled in the cylinder without leakage and repeatedly compress it through the piston 17 for repeated use. When working, hold the gun with your hand, aim the gun mouth 1 at the object to be fixed, and then press down hard until the gun mouth 1 reaches the bottom. At this time, the gun mouth 1 drives the gun head 2 backward to the limit position, and the end of the gun head 2 is against the safety trigger arm 6, and the safety trigger arm 6 is also compressed backward. The end of the safety trigger arm 6 has an induction magnet, which is sensed by the start sensor 8 after reaching the position. At this time, the controller 37 will determine that it can be fired, and then press the trigger 35. After the trigger 35 is pressed to the bottom, a switch 36 signal will be issued.

At this time, the nails in the clip 26 will be pushed into the trajectory 3 through the nail pusher assembly 27. At this time, the firing pin 16 will move forward against the nails and drive the nails into the object to be fixed, completing a nailing job. After a nail is driven in, an induction magnet is designed under the wheel 19 to sense the position with the stop sensor 30.After the wheel 19 reaches the designated position, the stop sensor 30 sends a signal to the controller 37, thereby stopping the motor 32, thus playing the role of nailing by air compression and improving practicality.
