Description
Technical Field
[0001] The utility model belongs to the technical field related to nail guns, and particularly relates to a multifunctional firing pin with a shock-absorbing structure. Background Art
[0002] In the construction, manufacturing, and maintenance industries, nail guns are a common tool, widely used in fixing, assembly, and repair operations. Traditional nail guns rely primarily on air pressure or spring force to drive nails. However, during the nailing process, the impact force of traditional nail guns is affected by a variety of factors, such as inconsistent spring compression stroke and air pressure fluctuations. This results in unstable nail fixing depth and firmness, affecting the quality of the work. When nailing, the recoil force generated by the nail gun not only affects the operator's comfort and work efficiency, but may also cause damage to the operator's arms and wrists with long-term use. During the nailing process, part of the energy generated by the firing pin when it contacts the nail is consumed by rebound and vibration, resulting in reduced energy utilization and affecting the nail's driving depth and speed. The power storage and firing structure design of traditional nail guns is often relatively complex, with high maintenance costs and prone to failure after long-term use.
[0003] To address these issues, this patent proposes a multifunctional striker design with a shock-absorbing structure. This design aims to provide a rationally designed, conveniently operated, safe, and reliable multifunctional striker suitable for a variety of operating environments, significantly improving both efficiency and quality. By innovating and optimizing traditional nail gun technology, this design not only addresses industry pain points but also opens up new directions for the development of nail gun technology.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] The utility model provides Figure 1-Figure 4The multifunctional firing pin with a shock-absorbing structure shown in the figure includes a gun nozzle 1, the upper end of the gun nozzle 1 is connected to the gun barrel 2, the upper end of the gun barrel 2 is sleeved with a pressure rod 3, and the gun barrel 2 is slidably connected to the lower end of the pressure rod 3, an explosive nail 4 is clamped inside the lower end of the gun nozzle 1, and an excitation firing pin 5 is downwardly penetrated from the center of the lower end of the gun barrel 2, the upper end of the excitation firing pin 5 is fixedly connected to a power storage disk 6, and the power storage disk 6 is slidably connected to the inside of the gun barrel 2, a buffer block 7 is provided at the lower end of the power storage disk 6, and the buffer block 7 is slidably connected to the inside of the gun barrel 2 and slidably connected to the outside of the excitation firing pin 5, a return spring 8 is provided at the lower end of the buffer block 7, and a power storage spring 9 is provided at the upper end of the power storage disk 6. The firing pin 5, the force storage disk 6 and the return spring 8 are elastically connected to the inside of the gun barrel 2 through the return spring 8 and the force storage spring 9. A limit ring 10 is provided on the outer side of the upper end of the force storage disk 6, and the limit ring 10 is fixedly connected to the inner wall of the gun barrel 2. A limit card slot 11 is provided inside the upper left end of the gun barrel 2. The right side of the lower end of the limit card slot 11 is connected to the limit slide 12, and the limit slide 12 is provided inside the inner wall of the upper left end of the gun barrel 2. A telescopic hole 13 is provided inside the upper left end of the buffer block 7. The telescopic hole 13 is internally slidably connected to the limit card head 14, and the left end of the limit card head 14 passes through the limit card slot 11, and the left end of the limit card head 14 protrudes On the outside of the left end of the gun barrel 2, the outer wall of the left end of the limiting clamp 14 is semi-cylindrical, and a limiting spring 15 is provided inside the right end of the limiting clamp 14, and is elastically connected to the inside of the telescopic hole 13 through the limiting spring 15. During the nailing process using the nail gun, the explosive nail 4 is clamped inside the lower end of the gun nozzle 1, and the lower end of the explosive nail 4 is aligned with the nailing position, and the pressure rod 3 is pressed down. Since the buffer block 7 can limit the position through the limiting slot 11 and the limiting clamp 14, the pressure rod 3 can compress the storage spring 9 and store force. When the lower end of the pressure rod 3 slides to the limiting clamp 14, the semi-cylindrical outer wall of the left end of the limiting clamp 14 is used. The limiting clamp 14 is squeezed into the telescopic hole 13 to release the position limit of the buffer block 7. At this time, the excitation firing pin 5, the storage disk 6 and the buffer block 7 slide downward rapidly under the action of the storage spring 9. At the same time, the left end of the limiting clamp 14 is inserted into the limiting slide groove 12 and slides downward inside the limiting slide groove 12, so that the lower end of the excitation firing pin 5 can quickly hit the upper end of the explosive nail 4. Since the explosive nail 4 is composed of a gunpowder bag at the upper end and a nail at the lower end, when the lower end of the excitation firing pin 5 hits the upper end of the explosive nail 4, the gunpowder bag can be detonated. The nail quickly pops out downward under the explosion impact of the gunpowder bag and is nailed into the inside of the nailing place, thereby realizing the nailing work.
[0025] Preferably, during the process of storing force with the force storage spring 9, the excitation firing pin 5, the force storage disk 6 and the buffer block 7 can be limited by the limit clamp 14 and inserted into the limit clamp 11, and when the pressure rod 3 is pressed down to the limit clamp 14, the lock between the limit clamp 11 and the limit clamp 14 can be released, so that the pressure rod 3 can compress the force storage spring 9 to a specific stroke, so that the force storage spring 9 can store force of a specific size, ensuring that the impact force of the excitation firing pin 5 on the explosive nail 4 is stable, and after the nailing is completed, the pressure rod 3 can return to its original position under the action of the force storage spring 9, and at the same time, the excitation firing pin 5, the force storage disk 6 and the buffer block 7 return to their original position under the action of the return spring 8, so that the limit clamp 14 is again inserted into the limit clamp 11, so that the nail gun returns to the excitation state again.
[0026] Preferably, a damping disc 16 is fixedly connected to the outer portion of the upper side of the firing pin 5, and the damping disc 16 is slidably connected to the inside of the buffer block 7 and fits with the inner wall of the lower end of the buffer block 7. A plurality of damping holes 17 are passed through the inner portion of the outer portion of the upper end of the damping disc 16. An energy absorbing spring 18 is provided on the upper end of the damping disc 16 and is elastically connected to the inside of the buffer block 7 through the energy absorbing spring 18. The energy absorbing spring 18 is sleeved on the outside of the firing pin 5. When the gunpowder bag of the explosive nail 4 explodes, the firing pin 5 will rebound rapidly upward under the force of the explosion, which will generate a large compression force on the force storage spring 9, causing the force storage spring 9 to be easily damaged, and will also cause the force of the explosion to be reduced, thereby reducing the nail driving force. At the same time, a large recoil force will be generated on the pressure rod 3. At this time, since hydraulic oil is arranged inside the buffer block 7, when the firing pin 5 rebounds quickly, the firing pin 5 can form resistance to the rebound through the movement of the damping disk 16 and the damping hole 17 inside the hydraulic oil, and can compress the energy absorption spring 18 through the damping disk 16 to absorb energy, thereby avoiding the firing pin 5 rebounding too quickly to cause damage to the force storage spring 9, and avoiding reducing the nail driving force. It can not only form protection for the force storage spring 9 and increase the service life of the force storage spring 9, but also reduce the attenuation rate of the explosion force, ensure the nail driving force, and at the same time reduce the recoil force of the firing pin 5 on the pressure rod 3, protecting the user from injury.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
