Description

Technical Field

[0001] This utility model relates to the field of pneumatic nail gun technology, specifically to a pneumatic nail gun with adjustable nail depth. Background Technology

[0002] A pneumatic nail gun is a tool that uses compressed air to quickly and accurately drive nails into materials such as wood, cement, and metal plates, achieving efficient fixing and connection. Its main function is to quickly fix materials, including wood, metal, and plastics. Applications include construction, decoration, and furniture manufacturing. In practical use, the depth of nail penetration needs to be determined according to different scenarios. For example, on decorative surfaces (such as furniture and thin boards), the penetration depth needs to be shallow to prevent surface dents or cracks, while on hard materials (such as hardwood and metal plates), the nail must be fully driven in. Currently, adjusting the penetration depth mostly involves adjusting the air pressure. However, after adjusting the air pressure, the operator cannot determine the penetration depth and needs to test 3-5 times on the same material to confirm depth stability. This method leads to significant waste of pneumatic nails. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect in the prior art that serious waste of air nails occurs when adjusting the depth of air nail penetration, and thus provide an air nail gun with adjustable nail depth that can quickly control the depth of air nail penetration and does not cause air nail waste.

[0004] Therefore, this utility model provides an air nail gun with adjustable nail depth, including a gun tongue and a safety bar disposed above the gun tongue. A nail-driving nozzle is disposed at the bottom of the gun tongue, and an extension sleeve is disposed on the safety bar and fitted outside the nail-driving nozzle. An adjustment component for adjusting the longitudinal movement of the extension sleeve is disposed on the side of the safety bar opposite to the extension sleeve. The adjustment component includes an adjustment rod for controlling the longitudinal movement of the extension sleeve and a rotating component for controlling the longitudinal movement of the adjustment rod. When the rotating component rotates, it can drive the adjustment rod to move up or down.

[0005] Furthermore: the side of the gun tongue is provided with a support step, the support step has a through hole for the adjusting rod to pass through, the rotating part is sleeved on the outside of the adjusting rod, the adjusting rod has an external thread, the rotating part has an internal thread that matches the external thread, the rotating part is located above the support step and abuts against the end face of the support step.

[0006] Furthermore, a connecting ring is provided on the side of the safety bar facing away from the extension sleeve, which is connected to the adjusting rod. The safety bar can pass through the connecting ring and be fixed to the connecting ring.

[0007] Furthermore, positioning blocks are provided on the upper and lower sides of the connecting ring, and the positioning blocks are threadedly connected to the bumper.

[0008] Furthermore, the outer end face of the rotating component is provided with several evenly distributed anti-slip teeth.

[0009] Furthermore: the nail nozzle is provided with a guide rail, the extension sleeve is wrapped around the outside of the nail nozzle, and the extension sleeve is provided with a guide groove that matches the side wall of the nail nozzle.

[0010] The technical solution of this utility model has the following advantages:

[0011] 1. This utility model provides an adjustable pneumatic nail gun. To adjust the depth of the nail penetration, the operator simply rotates a rotating component with their finger. This rotation causes an adjusting rod to move up and down. When the adjusting rod moves downwards, it pushes the extension sleeve away from the nozzle, increasing the distance between the nail head and the wall. This allows the nail to penetrate shallower into the wall when fired. Conversely, when the extension sleeve moves closer to the nozzle, the distance between the nail head and the wall decreases, allowing the nail to penetrate deeper into the wall. During adjustment, the air pressure of the nail gun remains unchanged, and the adjusted distance between the nail head and the wall can be visually observed. Therefore, after adjustment, multiple test shots are unnecessary, effectively saving on the number of nails needed and improving work efficiency.

[0012] 2. The present invention provides an adjustable nail gun with a support step on the side of the gun tongue. The support step has a through hole. The adjusting rod passes through the through hole and is fixed to the side of the gun tongue. The adjusting rod is a threaded shaft and the rotating part is an internally threaded assembly. The two sections are engaged by threads. When the rotating part is rotated by an external force, the inclined surface of the internal thread of the rotating part forces the adjusting rod to move up and down. Attached Figure Description

[0023] Example

[0024] This embodiment provides a pneumatic nail gun with adjustable nail depth, including a gun tongue 1 and a safety bar 2 disposed above the gun tongue 1. A nail-driving nozzle 3 is disposed at the bottom of the gun tongue 1. An extension sleeve 4 is disposed on the safety bar 2 and sleeved outside the nail-driving nozzle 3. An adjustment component 5 for adjusting the longitudinal movement of the extension sleeve 4 is disposed on the side of the safety bar 2 facing away from the extension sleeve 4. The adjustment component 5 includes an adjustment rod 51 for controlling the longitudinal movement of the extension sleeve 4 and a rotating component 52 for controlling the longitudinal movement of the adjustment rod 51. When the rotating component 52 rotates, it can drive the adjustment rod 51 to move up or down.

[0025] The specific improvements mentioned above are as follows: Figure 1 and Figure 2 As shown, compared to existing technologies, adjusting the depth of the pneumatic nail insertion only requires the operator to rotate the rotating part 52 with their finger. The rotation of the rotating part 52 causes the adjusting rod 51 to move up and down. When the adjusting rod 51 moves downwards, it pushes the extension sleeve 4 towards the side away from the nozzle 1, thus increasing the distance between the nail nozzle 3 and the wall. This allows the nail to hit a shallower area of ​​the wall when it is fired outwards. Conversely, when the extension sleeve 4 moves towards the side closer to the nozzle 1, the distance between the nail nozzle 3 and the wall shortens, allowing the nail to hit a deeper area of ​​the wall when it is fired outwards. During the adjustment process, the air pressure of the pneumatic nail gun remains unchanged, and the adjusted distance between the nail nozzle 3 and the wall can be observed visually. Therefore, after adjusting the distance, multiple test shots are unnecessary. This not only effectively saves on the number of pneumatic nails needed but also significantly improves work efficiency.

[0026] Based on the above embodiments: a support step 11 is provided on the side of the gun tongue 1, the support step 11 has a through hole 12 for the adjusting rod 51 to pass through, the rotating member 52 is sleeved on the outside of the adjusting rod 51, the adjusting rod 51 has an external thread, the rotating member 52 has an internal thread that matches the external thread, the rotating member 52 is located above the support step 11 and abuts against the end face of the support step 11.

[0027] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a support step 11 is provided on the side of the gun tongue 1. The support step 11 has a through hole 12. The adjusting rod 51 passes through the through hole 12 and is fixed to the side of the gun tongue 1. The adjusting rod 51 is a threaded shaft, and the rotating part 52 is an internal threaded assembly. The two sections are engaged by threads. When the rotating part 52 is rotated by an external force, the inclined surface of the internal thread of the rotating part 52 forces the adjusting rod 51 to move up and down.

[0028] Based on the above embodiments: the safety rod 2 is provided with a connecting ring 6 connected to the adjusting rod 51 on the side facing away from the extension sleeve 4, and the safety rod 2 can pass through the connecting ring 6 and be fixed to the connecting ring 6.

[0029] Based on the above embodiment: positioning blocks 7 are provided on the upper and lower sides of the connecting ring 6, and the positioning blocks 7 are threadedly connected to the safety rod 2.

[0030] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, the positioning block 7 includes an anti-loosening nut fixed to the upper end of the connecting ring 6 and an anti-loosening block fixed to the lower end of the connecting ring 6. The safety rod 2 is connected to the adjusting rod 51 on the side facing away from the extension sleeve 4. To facilitate quick connection between the two, the adjusting rod 51 is passed through the through hole 12 of the support step 11, and then an anti-loosening nut is passed through the adjusting rod 51 first, and then the adjusting rod 51 is passed through the connecting ring 6. Finally, the anti-loosening block is screwed into the adjusting rod 51 and abuts against the lower end face of the connecting ring 6.

[0031] Based on the above embodiments: the outer end face of the rotating component 52 is provided with a plurality of evenly distributed anti-slip teeth 53.

[0032] The specific improvements mentioned above are as follows: Figure 2 As shown, by setting the anti-slip teeth 53, the operator can effectively prevent their fingers from slipping on the rotating part 52 when rotating the anti-slip teeth 53.

[0033] Based on the above embodiments: the nail nozzle 3 is provided with a guide rail 31, the extension sleeve 4 is wrapped around the outside of the nail nozzle 3, and the extension sleeve 4 is provided with a guide groove 41 that is adapted to the side wall of the nail nozzle.

[0034] The specific improvements mentioned above are as follows: Figure 3 As shown, the adjusting rod 51 and the extension sleeve 4 are arranged in parallel. When the operator rotates the rotating part 52, the adjusting rod 51 moves downward, which drives the safety rod 2 to move downward. Thus, the safety rod 2 drives the extension sleeve 4 to move downward along the nail. In order to ensure that the extension sleeve 4 can fit against the side wall of the nail, the extension sleeve 4 is provided with a guide groove 41 that matches the side wall of the nail. Through the setting of the guide groove 41, not only can the extension sleeve 4 move along the setting direction of the nail, but the contact area between the extension sleeve 4 and the nail can also be increased, so that the extension sleeve 4 can move vertically more smoothly.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
