Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic nail guns, in particular to a firing pin of a coil nail gun. Background Art

[0002] Pneumatic coil nail guns can be used for container pallets, large wooden packaging boxes to make fences, wooden structure connections for houses, wooden furniture and other wooden structures. They can be nailed together quickly, saving labor costs.

[0003] The coil nail gun is composed of a gun body and a nail box. The gun body consists of a gun shell, a cylinder, a retractor, a trigger assembly, a firing pin assembly (gun tongue), a buffer pad, a gun mouth and a bumper assembly. The pressure difference between compressed air and the atmosphere is used to make the firing pin (piston) reciprocate in the cylinder through the trigger switch; the clip assembly consists of accessories such as a nail pusher, a fixed clip, and a movable clip. The nail is sent to the gun cover slot through a compression spring or a tension spring, and the nail is driven out when the firing pin comes out of the gun mouth.

[0004] The existing coil nail gun firing pin assembly is mainly composed of a firing pin and a piston assembly, which is generally threaded or pin-locked. When the above method is activated under high air pressure, it is easy to cause the firing pin and the piston to loosen, resulting in the nail not being driven into place or the firing pin breaking.

[0005] Therefore, we propose a coil nail gun firing pin to solve the above problems. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figures 1-3 , the present utility model provides a technical solution: a rammer for a coil nail gun, comprising: a piston 1 and a rammer body 2, the piston 1 and the rammer body 2 are integrally formed by die molding;

[0031] The piston 1 and the rammer body 2 are coaxially arranged;

[0032] Two parallel sealing ring grooves 11 are formed on the side surface of the piston 1, and sealing rings are embedded and sleeved in the sealing ring grooves 11 for sealing between the piston 1 and the barrel of the coil nail gun;

[0033] A thickening section 21 is arranged at the connection between the upper end of the rammer body 2 and the piston 1, and the thickening section 21 is used to strengthen the connection between the rammer body 2 and the piston 1;

[0034] A cap head 3 is integrally arranged at the upper end of the piston 1, and the cap head 3 strengthens the force application points of the piston 1 and the rammer body 2 to prevent the rammer body 2 from piercing through the cap head 3.

[0035] Working principle: By integrally forming the piston 1 and the rammer body 2, the connection between the piston 1 and the rammer body 2 is strengthened to prevent the piston 1 and the rammer body 2 from loosening.

[0036] Embodiment 2

[0037] Please refer to Figures 4-5 , the present utility model provides a technical solution: a rammer for a coil nail gun, comprising: a rammer body 2. The difference between this embodiment and Embodiment 1 is that a guide sleeve 4 is slidably sleeved on the rammer body 2;

[0038] The guide sleeve 4 includes a guide cylinder 42, a guide hole 44 is formed through the guide cylinder 42, and the rammer body 2 slidably penetrates through the guide hole 44;

[0039] The guide cylinder 42 is fixedly connected to a connecting sleeve 41 through a reinforcing rib 43, and the connecting sleeve 41 is fixedly connected to the inner wall of the gun barrel to realize the fixation of the guide cylinder 42;

[0040] When the rammer body 2 moves under the action of high-pressure gas to strike the nail, the rammer body 2 slides relative to the guide cylinder 42. Under the action of the guide cylinder 42, the stability of the rammer body 2 moving in a straight line is strengthened. At this time, the guide cylinder 42 slides to the root of the rammer body 2;

[0041] When the striker body 2 retracts to the starting position, the tip of the striker body 2 slides to the upper port of the guide cylinder 42, and the reserved part of the tip of the striker body 2 is inside the guide cylinder 42, facilitating the sliding of the striker body 2 next time.

[0042] Another difference between this embodiment and the first embodiment is that a fixing collar 6 is fixedly sleeved on the root of the striker body 2, and a buffer pad 5 is movably sleeved on the fixing collar 6. When the striker body 2 slides relative to the guide sleeve 4, the buffer pad 5 is used to buffer the impact between the piston 1 and the guide sleeve 4.
