Detailed Implementation

[0034] To make the technical problems, solutions, and beneficial effects of this application clearer, the following detailed description of an electric nail gun lifting device and nail gun disclosed in this application, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] Example 1

[0036] Please see Figure 1 This embodiment provides an electric nail gun lifting device, including a lifting wheel 1 and a nail gun firing pin 2. A transmission component is connected to the lifting wheel 1 and is connected to the nail gun firing pin 2. The transmission component includes a transmission pin 3, which is arranged along the circumference of the lifting wheel 1. The first end of the transmission pin 3 is connected to the lifting wheel 1, and the second end of the transmission pin 3 is movably connected to the nail gun firing pin 2. The transmission pin 3 drives the nail gun firing pin 2 to move axially.

[0037] This utility model has a simple structure and compact design. The lifting wheel 1 and the transmission pin 3 drive the striking pin to move, and the torque transmission is simple. Moreover, the transmission pin 3 can be heat treated separately, and the material of the transmission pin 3 can be adjusted as needed. It can be replaced at any time after wear, which solves the limitations of traditional lifting wheels and significantly improves the performance and service life of electric nail guns. It not only has higher wear resistance and reliability, but also reduces maintenance costs and has good versatility and adaptability.

[0038] In this embodiment, as Figure 2 As shown, the lifting wheel 1 includes a main body 4, a first connecting part 5, and a second connecting part 6. The first connecting part 5 and the second connecting part 6 are respectively disposed on the left and right sides of the main body 4. A transmission pin connecting part is connected to the main body 4, and the transmission pin 3 is detachably connected to the transmission pin connecting part.

[0039] Specifically, the main body 4 is roughly circular with a notch at the top. The main body 4 consists of two wheel plates with a gap between them, each with weight-reducing holes. A transmission pin connection is located on the outer periphery of the main body 4 and is positioned along its circumference. The transmission pin 3 is laterally positioned on the main body 4. The first connecting part 5 and the second connecting part 6 are mounting structures located on both sides of the main body 4. They are integrally machined with the main body 4 and are coaxially aligned with it. Both the first connecting part 5 and the second connecting part 6 are perpendicular to the main body 4.

[0040] like Figure 2 , Figure 3 As shown, the transmission pin connection includes a plurality of mounting holes 7, which are arranged along the axial direction of the main body 4 and are evenly distributed along the outer periphery of the main body 4. A plurality of transmission pins 3 are sequentially arranged in the mounting holes 7 of the transmission pin connection, and the two ends of the transmission pins 3 are interference-fitted in the mounting holes 7. The outer periphery of one end of the mounting hole 7 is smaller than the diameter of the transmission pin 3, which can axially limit the transmission pin 3, and the size of the other end is adapted to the size of the transmission pin 3.

[0041] In this embodiment, the structure of the mounting hole 7 is adapted to the structure of the transmission pin 3, achieving a stable connection. For example... Figure 4 As shown, the transmission pin 3 has a cylindrical structure, and the axial length of the transmission pin 3 is adapted to the axial dimension of the main body 4. The two ends of the transmission pin 3 do not extend out of the mounting holes 7.

[0042] In this embodiment, the material, hardness, and wear resistance of the transmission pins 3, which are evenly distributed mounting holes 7 and interference-fitted within the mounting holes 7, can be adjusted and changed as needed. The transmission pins 3 can be heat-treated individually, and can be replaced at any time when a single transmission pin is worn. This provides good interchangeability and easy maintenance, which not only reduces the cost of use but also significantly extends the service life of the components compared to gear transmission.

[0043] Furthermore, such as Figure 5 As shown, the first connecting part 5 is provided with a first cover 8, and the second connecting part 6 is provided with a second cover 9. The first cover 8 and the second cover 9 are respectively provided on the left and right sides of the main body part 4, and the inner structure of the first cover 8 and the second cover 9 matches the two sides of the main body part 4 of the lifting wheel 1.

[0044] Specifically, such as Figure 4 As shown, the first cover 8 and the second cover 9 are respectively disposed on the outer periphery of the first connecting part 5 and the second connecting part 6. The first cover 8, the second cover 9 and the main body part 4 are coaxially disposed, and the radial dimensions of the first cover 8 and the second cover 9 are adapted to the main body part 4.

[0045] The first cover 8 and the second cover 9 cover both ends of the main body 4. The first cover 8 and the second cover 9 are respectively disposed on the outer sides of the two ends of the transmission pin 3, and the inner side of the first cover 8 can abut against the end of the transmission pin 3 to fix the end of the transmission pin 3 axially, prevent the transmission pin 3 from coming out, and stably limit it in the mounting hole 7 of the lifting wheel.

[0046] Example 2

[0047] like Figure 6 As shown, this embodiment provides an electric nail gun lifting device, including a lifting wheel 1 and a nail gun firing pin 2. A transmission component is connected to the lifting wheel 1 and is connected to the nail gun firing pin 2. The transmission component includes a transmission pin 3, which is arranged along the circumference of the lifting wheel 1. The first end of the transmission pin 3 is connected to the lifting wheel 1, and the second end of the transmission pin 3 is movably connected to the nail gun firing pin 2. The transmission pin 3 drives the nail gun firing pin 2 to move axially.

[0048] like Figure 7 , Figure 8As shown, the lifting wheel 1 includes a main body 4, a first connecting part 5, and a second connecting part 6. The first connecting part 5 and the second connecting part 6 are respectively disposed on the left and right sides of the main body 4. A transmission pin connecting part is connected to the main body 4, and the transmission pin 3 is detachably connected to the transmission pin connecting part.

[0049] The structure described above in this embodiment is the same as that in Embodiment 1. The main differences are in the outer peripheral structure of the lifting wheel, the structure of the transmission pin, and its connection and fixing method, as detailed below.

[0050] In this embodiment, the main body 4 is generally circular with a notch at the top. The main body 4 consists of two wheel plates with a gap between them, and the wheel plates have weight-reducing holes. The transmission pin connection is located on the outer periphery of the main body 4 and is arranged along the circumference of the main body 4. The transmission pin 3 is arranged laterally on the main body 4. The first connecting part 5 and the second connecting part 6 are mounting structures located on both sides of the main body 4. The first connecting part 5 and the second connecting part 6 are integrally machined with the main body 4 and are coaxially arranged with the main body 4. The first connecting part 5 and the second connecting part 6 are both perpendicular to the main body 4.

[0051] Specifically, the transmission pin connection includes several mounting holes 7, which are arranged along the axial direction of the main body 4 and are evenly distributed along the outer periphery of the main body 4. Several transmission pins 3 are sequentially arranged in the mounting holes 7 of the transmission pin connection. The mounting holes 7 are stepped holes with an end inner diameter larger than the middle inner diameter. One end of the mounting hole 7 is provided with a groove-shaped limiting structure with an inner diameter smaller than the end diameter of the transmission pin 3. The other end is adapted to the size of the transmission pin 3. The limiting member is used to axially limit the transmission pin 3 in the mounting hole, thereby axially limiting one end of the transmission pin 3 and preventing its end from moving arbitrarily. The other end is fixed by the limiting member, making installation convenient and transmission pin replacement easy.

[0052] like Figure 7 , Figure 9 As shown, in this embodiment, the structure of the mounting hole 7 is adapted to the structure of the transmission pin 3 to achieve a stable connection. The transmission pin 3 is a cylindrical pin structure with an end cap. The transmission pin 3 includes a snap-fit ​​end 31, a limiting end 32, and a connecting part 33 disposed between the snap-fit ​​end 31 and the limiting end 32. Both the snap-fit ​​end 31 and the connecting part 33 of the transmission pin 3 are cylindrical structures. The outer diameter of the snap-fit ​​end 31 is larger than the outer diameter of the connecting part 33. The outer diameter of the snap-fit ​​end 31 is adapted to the end size of the lifting wheel mounting hole 7. The end of the transmission pin 3 is snapped into the mounting hole 7 through the snap-fit ​​end 31 and the connecting part 33. The limiting end 32 is provided with a limiting groove 34, and the limiting element is disposed in the limiting groove 34.

[0053] Specifically, the transmission pin 3 is an integrally machined structure. The axial length of the snap-fit ​​end 31 and the connecting part 33 of the transmission pin 3 is adapted to the axial dimension of the main body part 4 of the lifting wheel 1. The limiting end 32 of the transmission pin 3 extends out of the mounting hole 7 and is located on the side of the main body part 4.

[0054] The limiting groove 34 is arranged circumferentially along the limiting end 32. The limiting groove 34 is an annular groove structure. The outer diameter of the limiting groove 34 is the same as the outer diameter of the connecting part 33, and the depth of the limiting groove 34 matches the size of the limiting component. The limiting component axially fixes the transmission pin 3, making it stably connected to the lifting wheel 1. When a single transmission pin 3 wears, it can be disassembled and installed at any time, which provides good interchangeability and simple maintenance. This not only reduces the cost of use, but also significantly extends the service life of the components compared to gear transmission.

[0055] Specifically, such as Figure 10 As shown, the limiting component is a limiting snap ring 10, which snaps into the limiting groove 34 of the transmission pin 3. The wire diameter of the limiting snap ring 10 matches the depth of the limiting groove 34, ensuring stable axial limiting after the snap ring is embedded, preventing the transmission pin 3 from falling out, and providing good stability. At least one limiting snap ring 10 is installed in the limiting groove 34. The limiting snap ring 10 is an outer circular snap ring structure. The axial limiting of the transmission pin 3 is achieved by the limiting snap ring 10. Compared with the existing press-fit method for transmission pins, it is not only easier to install and reduces assembly difficulty, but also the snap ring is easy to disassemble and maintain.

[0056] Furthermore, the type and number of limit springs 10 specifically set in the limit groove 34 can be adapted and adjusted according to actual usage requirements to increase reliability and impact resistance. Moreover, limit retaining rings or buffer pads adapted to the limit springs 10 can be simultaneously set in the limit groove 34 to absorb the impact vibration of the firing pin, reduce the risk of the springs loosening due to high-frequency vibration, avoid overload causing deformation of the springs, affect the performance, and extend the service life of the components.

[0057] Furthermore, in this embodiment, as Figure 7 As shown, a first guide plate 11 is also connected to the first connecting part 5, and a second guide plate 12 is connected to the second connecting part 6. The first guide plate 11 and the second guide plate 12 are respectively arranged on the left and right sides of the main body part 4, and the inner structure of the first guide plate 11 and the second guide plate 12 matches the two sides of the lifting wheel main body part 4.

[0058] Specifically, the first guide plate 11 and the second guide plate 12 are respectively disposed on the outer periphery of the first connecting part 5 and the second connecting part 6. The first guide plate 11, the second guide plate 12 and the main body part 4 are coaxially disposed, and the diameter of the first guide plate 11 and the second guide plate 12 is smaller than the radial dimension of the main body part 4. The first guide plate 11 and the second guide plate 12 can cover the inner periphery structure on both sides of the main body part 4. The transmission pin 3 is disposed on the outer periphery of the first guide plate 11 and the second guide plate 12.

[0059] Furthermore, the lifting wheel in Embodiments 1 and 2 can also be equipped with a pawl and a pawl torsion spring to realize the elastic transmission of the lifting wheel. This is an existing technical structure, and its specific structure and working principle will not be described in detail here.

[0060] Furthermore, based on Embodiment 1 and Embodiment 2, the transmission pin 3 is engaged with the side teeth of the nail gun firing pin 2 to realize the actuation and torque transmission, thereby driving the firing pin to move back and forth.

[0061] like Figure 11 As shown, the nail gun firing pin of this utility model adopts a split structure design, including a firing pin body 21 and a meshing tooth part 22. The firing pin body 21 and the meshing tooth part 22 are detachably connected. The meshing tooth part 22 is provided with a number of teeth arranged along its length direction. The meshing tooth part 22 is meshed with the transmission pin 3.

[0062] Specifically, the main body 21 of the firing pin and the meshing tooth 22 are connected by insertion, and then the end is fixed by a pin, realizing the convenient connection of the nail gun firing pin 2. Moreover, through the split disassembly structure, the tooth of the firing pin can be selected according to the material and heat treatment method as needed, and can be replaced as needed when worn, which is convenient for disassembly and installation.

[0063] Example 3

[0064] Furthermore, such as Figure 12 As shown in the figure, this utility model embodiment also provides a nail gun, including a driving component, a transmission component and a guiding component, and also includes an electric nail gun lifting device.

[0065] This utility model provides a simple and compact electric nail gun lifting device and nail gun. The lifting wheel and transmission pin drive the firing pin, facilitating torque transmission. The transmission pin is detachable, employing either an interference fit in the lifting wheel mounting hole or a spring-loaded limiter, allowing for easy disassembly and replacement. Furthermore, the transmission pin can undergo individual heat treatment, its material can be adjusted as needed, and it can be replaced at any time after wear. This overcomes the limitations of traditional lifting wheels, improves the maintenance efficiency and stability of the electric nail gun firing pin assembly, significantly enhances the performance and service life of the electric nail gun, and not only offers higher wear resistance and reliability but also reduces maintenance costs, demonstrating good versatility and adaptability.
