Technical Field
[0001] This utility model relates to the field of nail gun technology, specifically to a nail gun shock absorption device. Background Technology
[0002] A nail gun is a tool used to fire nails or similar objects to fix them to a surface. Nail guns typically use blank cartridges, gas, or compressed air to generate power, driving the nail or similar object into wood, metal, walls, or other materials. In related technologies, a nail gun generally includes a nail gun body and a handle connected to the body. The nail gun body includes a housing and a nail-firing mechanism housed within the housing. The nail-firing mechanism drives the nail or similar object out of the housing, impacting and fixing it to the surface. Users typically operate the nail gun by holding the handle with one hand.
[0003] The working principle of existing electric nail guns is to use electrical energy to drive mechanical devices to quickly drive nails into hard materials. During use, the nail gun drives the nail into the material through high-intensity impact force, which is transmitted to the user's hand and arm through the gun body. These vibrations not only affect the user's comfort and operating accuracy, but also accelerate equipment wear and increase safety risks. Utility Model Content

The piston 303 is embedded in the cylinder 304 and slidably connected to the cylinder 304. A through hole is opened on the side of the piston 303. Hydraulic oil is filled in the cylinder 304. The slide rod 302, piston 303 and cylinder 304 constitute a hydraulic damper. The working principle of the damper is to consume energy by using the resistance generated when the oil passes through the small hole on the piston 303.
[0036] An adjusting ring 307 is rotatably mounted on the outside of the cylinder body 304. A locking block 306 is mounted on the outside of the cylinder body 304, and the locking block 306 engages with the adjusting ring 307. A spring 310 is nested on the outside of the cylinder body 304, and the spring 310 abuts against the adjusting ring 307. The adjusting ring 307 rotates to control its own position to adjust the preload of the spring 310. When using a nail gun, the shock-absorbing part 3 located inside the grip 2 can absorb the impact force, reducing the impact force transmitted to the user's hand. The preload of the spring 310 can be adjusted by rotating the adjusting ring 307. The greater the preload, the stronger the damping force of the entire shock-absorbing part 3, thus adapting to different usage environments.
[0037] Example 2
[0038] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a nail gun shock absorber, disposed at the bottom of the gun body 1, including a grip 2 and a shock absorber 3.
[0039] A slide groove 202 is provided inside the outer shell 201. The slide 204 is embedded in the slide groove 202 and is laterally slidably connected to the outer shell 201, allowing the slide 204 to slide and move inside the outer shell 201.
[0040] An installation groove 203 is provided inside the outer casing 201. The installation groove 203 is connected to the slide groove 202. The connecting block b305 is fixedly installed inside the installation groove 203 by bolts. The shock absorber 3 can be installed inside the installation groove 203. When using the nail gun, the shock absorber 3 set inside the grip 2 absorbs the impact force and reduces the impact force transmitted to the user's hand.
[0041] Example 3
[0042] Please see Figure 5 , Figure 6 and Figure 7 This embodiment provides a technical solution: a nail gun shock absorber, disposed at the bottom of the gun body 1, including a shock absorber 3, a cylinder 304, and an adjusting ring 307.
[0043] The adjusting ring 307 has a circular hole inside. The cylinder body 304 passes through the hole and is laterally slidably connected to the adjusting ring 307, allowing the adjusting ring 307 to slide along the cylinder body 304.
[0044] An adjustment handle 309 is integrally provided on the side of the adjustment ring 307. A hole is provided on the side of the housing 201. The handle 205 passes through the hole and extends to the outside of the housing 201. The adjustment ring 307 is also rotatably connected to the cylinder 304. The adjustment ring 307 can be rotated outside the cylinder 304 by turning the handle 205.
[0045] Spring 310 is located between connecting block a301 and adjusting ring 307. One end of spring 310 is fixedly connected to the side of connecting block a301. The preload of spring 310 can be adjusted by moving the adjusting ring 307.
[0046] A slot 308 is provided on the side of the adjusting ring 307. The slot 308 engages with the locking block 306. The position of the adjusting ring 307 can be fixed by locking the locking block 306 into the slot 308. There are three slots 308 in total, which are evenly distributed on the side of the adjusting ring 307 in a ring-shaped arrangement. The three slots 308 are at different horizontal heights, and adjacent slots 308 are connected by a transition slope. By controlling the locking block 306 to engage in different slots 308, the horizontal position of the adjusting ring 307 can be controlled, thereby adjusting the preload of the spring 310. The greater the preload, the stronger the damping force of the entire shock absorber 3, thus adapting to different usage environments.
[0047] Working principle: First, connect the gun body 1 to the power supply. During use, the electric nail gun uses electrical energy to drive the mechanical device, generating a high-speed impact force to quickly drive the nail into the material. The shock-absorbing part 3 inside the grip 2 absorbs the impact force, reducing the impact force transmitted to the user's hand. Furthermore, by moving the handle 205, the adjusting ring 307 can be rotated outside the cylinder 304. Figure 5 and Figure 6 As shown, the locking block 306 can be inserted into different slots 308, which can control the horizontal position of the adjusting ring 307, thereby adjusting the preload of the spring 310. The tighter the spring 310 is compressed, the greater the preload, and the stronger the damping force of the entire shock absorber 3. The stronger the damping force, the faster the vibration can be suppressed and the amplitude reduced. Conversely, the weaker the damping force, the more comfortable the shock absorption effect is provided, thus adapting to different usage environments.
