Technical Field

[0001] The present application relates to the field of nail guns, and more particularly to a new type of multi-functional nail gun head. Background Art

[0002] A nail gun is a tool commonly used in the fields of construction, decoration, and other construction works. It is mainly used to drive nails into various materials such as concrete, steel, or wood for fixing operations. Traditional nail guns usually consist of a gun body, a firing pin, a barrel, a nozzle, etc., and the firing pin is triggered to move by a firing device to shoot out the nails.

[0003] Regarding the above related technologies, the inventor believes that the current market nail gun heads have the disadvantages of complex installation and disassembly, inconvenient force adjustment, and inconvenient head adjustment. Summary of the Utility Model

[0004] In order to overcome the above disadvantages in the related technologies, the present application provides a new type of multi-functional nail gun head.

[0005] The new type of multi-functional nail gun head provided by the present application adopts the following technical solutions:

[0006] A new type of multi-functional nail gun head includes a gun head body, and the gun head body includes a nail driving seat, a barrel, a nozzle, a locking adjustment ring, a positioning lock pin, a firing pin, and a striking arm. After the nail driving seat, the barrel, the nozzle, the locking adjustment ring, the positioning lock pin, the firing pin, and the striking arm are assembled together, the gun head body is formed.

[0007] By adopting the above technical solutions, the locking adjustment ring and the positioning lock pin can accurately adjust the nail driving force according to different materials and environmental conditions, and the nails are firmly driven into the target position, thereby improving the construction accuracy. Combining the designs of the barrel, the nozzle, the firing pin, and the striking arm, the gun head can adapt to various nail types and sizes, increasing the applicable range of the tool and meeting different construction requirements. The integrated design makes the components compactly combined, facilitating carrying and use, reducing work interruptions caused by the loss or damage of components, and the positioning lock pin ensures locking at the appropriate angle and position, avoiding safety hazards caused by misoperations. The design of the striking arm can effectively prevent rebounds, not only improving the construction efficiency and quality, but also enhancing the user's operation experience and safety.

[0008] Optionally, the firing pin is connected to the nail driving seat in an insertable manner, and the tail end of the firing pin is inserted into one end of the hole of the nail driving seat to be connected and combined with the nail driving seat.

[0009] By adopting the above technical solution, the plug-in connection method makes the installation and disassembly of the firing pin simpler and more convenient. When the firing pin is worn or damaged, it can be quickly replaced without the need for complex tools or steps. The plug-in connection can ensure the stability of the firing pin during use, reduce vibration and displacement, improve the accuracy and consistency of the nail shooting, make the overall structure more compact, reduce the weight and volume of the tool. Since the replacement and maintenance are convenient, the service life of the nail gun can be extended, the maintenance and replacement costs can be reduced, and the overall economy of the tool is improved.

[0010] Optionally, the barrel is plug-in connected to the nail driving seat. The tail end of the barrel is inserted into the other end of the hole of the nail driving seat and connected to the nail driving seat in combination. During the firing process of the gun head body, the barrel slides back and forth in the hole of the nail driving seat.

[0011] By adopting the above technical solution, the plug-in connection design between the barrel and the nail driving seat, and the barrel can slide back and forth in the hole of the nail driving seat, making the installation and disassembly of the barrel easier, and the assembly and maintenance of the tool can be quickly completed, reducing the operation time. The barrel can slide back and forth in the hole of the nail driving seat, providing greater flexibility. During the firing process, the sliding design of the barrel can absorb part of the recoil force, reduce the influence of vibration on the shooting accuracy, improve the accuracy of the nail shooting, and is convenient for cleaning and inspection. The sliding connection reduces the wear of the fixed connection components, thus extending the service life of the tool. The nail gun not only improves the operation convenience and safety, but also enhances the adaptability and durability.

[0012] Optionally, the gun head body includes a positioning locking pin. An axial U-shaped groove is provided on the circumferential surface of the barrel. The positioning locking pin is inserted and installed in the U-shaped groove. The positioning locking pin installed on the U-shaped groove limits the axial sliding stroke of the barrel.

[0013] By adopting the above technical solution, the positioning locking pin is inserted into the U-shaped groove, effectively limiting the sliding range of the barrel, ensuring that the barrel moves within the set stroke, thereby improving the accuracy and consistency of the nail shooting.

[0014] By restricting the sliding stroke of the barrel, it avoids component wear or detachment caused by excessive sliding, reduces the risk of equipment failure. The cooperation between the locking pin and the U-shaped groove makes the barrel more stable during the sliding process, reduces vibration and noise caused by improper sliding, improves the shooting stability and comfort, and can quickly adjust the sliding stroke of the barrel according to different usage requirements.

[0015] Optionally, the gun head body includes a nozzle. The nozzle is provided with an external thread, and the front end of the barrel is provided with a cylindrical internal thread. The external thread of the nozzle is screwed to the cylindrical internal thread at the front end of the barrel.

[0016] By adopting the above technical solution, the threaded connection makes the installation and disassembly of the nozzle simple and fast. Users can replace or maintain components without additional tools, and it provides a firm connection, enhancing the overall stability and safety of the nail gun. When the nozzle wears or gets damaged, users can quickly replace it without disassembling the entire gun head, thus reducing maintenance time and costs. The threaded connection allows different types or specifications of nozzles to be interchangeable, with strong adaptability.

[0017] Optionally, the gun head body includes a locking and adjusting ring, which is sleeved on the axial bottom end face of the external thread of the nozzle. The nozzle rotates to axially lock the locking and adjusting ring between the axial bottom end face of the external thread of the nozzle and the front end face of the barrel. The locking and adjusting ring controls the driving force and depth of nail driving.

[0018] By adopting the above technical solution, the locking and adjusting ring allows for precise adjustment of the driving force and depth of the nails according to different materials and construction requirements. Simply rotating the locking and adjusting ring can adjust the nail driving parameters without complex operations or additional tools, enhancing the convenience and efficiency of use. By precisely adjusting the nail driving force, it reduces material damage caused by excessive force or nail loosening caused by insufficient force, thus improving construction safety. The design of the locking and adjusting ring ensures a firm connection between the nozzle and the barrel, reducing the risk of vibration and loosening, increasing the stability of equipment operation, and by reasonably controlling the nail driving force and depth, reducing excessive wear on the nail gun and materials, extending the service life of the equipment and construction materials, and increasing the applicable range of the tool.

[0019] Optionally, the gun head body includes a striking arm. The tail end of the barrel presses against the striking arm. When the head of the barrel is pressed down, the barrel triggers the trigger linkage of the gun head body to fire a nail.

[0020] By adopting the above technical solution, the tail end of the barrel presses against the striking arm, and the head of the barrel is pressed down to trigger the trigger linkage of the gun head body to fire a nail, simplifying the user's operation steps, enhancing the convenience and efficiency of use. The striking arm will only trigger the firing action when the barrel is pressed down, effectively preventing misoperation or accidental triggering, improving the safety of use, and by controlling the pressing force and speed, further precisely controlling the nail driving force and depth, improving the accuracy and stability of nail driving.

[0021] Optionally, the positioning locking pin is installed on the nail driving seat. One end of the positioning locking pin radially enters the hole for installing the barrel in the nail driving seat inward. An axial U-shaped groove is provided on the circumferential surface of the barrel. One end of the positioning locking pin is located in the U-shaped groove. When the barrel slides axially, the U-shaped groove slides axially relative to the positioning locking pin;

[0022] The positioning locking pin restricts the circumferential rotation of the barrel.

[0023] By adopting the above technical solutions, the positioning locking pin effectively restricts the circumferential rotation of the barrel, ensuring that the barrel always remains in the correct direction, improving the shooting accuracy and consistency. The cooperation between the U-shaped groove and the positioning locking pin enables the barrel to slide smoothly axially, reducing the offset and vibration during the sliding process, enhancing the stability of the device, and being easy to install and maintain. The components can be easily inspected and adjusted, improving safety and extending the service life, and enhancing the accuracy.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The locking adjustment ring and the positioning locking pin can accurately adjust the shooting force according to different materials and environmental conditions. The nail is firmly driven into the target position, thereby improving the construction accuracy.

[0042] The following further describes the present application in detail with reference to the attached Figure 1-8 drawings.

[0043] An embodiment of the present application discloses a new type of multi-functional nail gun head. Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, the nail head body 8 includes a nail driving base 1, a barrel 2, a nozzle 3, a locking adjustment ring 4, a positioning lock pin 5, a firing pin 6 and a striking arm 7. After the nail driving base 1, the barrel 2, the nozzle 3, the locking adjustment ring 4, the positioning lock pin 5, the firing pin 6 and the striking arm 7 are assembled together, they form the nail head body 8. The nail driving base 1 serves as the basic support structure of the nail head, carrying other components, and is combined with the firing pin 6 and the barrel 2 through an insertion connection, providing a stable assembly platform. The barrel 2 is combined with the nail driving base through an insertion connection and slides back and forth within the hole of the nail driving base 1. The circumferential surface of the barrel 2 is provided with an axial U-shaped groove to cooperate with the positioning lock pin 5 for limit and sliding guidance, restricting the axial sliding stroke and circumferential rotation of the barrel 2. The nozzle 3 is screwed to the internal thread at the front end of the barrel 2 through an external thread, facilitating installation and replacement. The installation, disassembly and adjustment of components become simple and fast, without the need for additional tools, and provide stable fixation. The locking adjustment ring 4 is sleeved on the axial bottom end face of the external thread of the nozzle 3, and by rotating the locking adjustment ring 4, the force and depth of nail driving can be controlled to meet different construction requirements. The firing pin 6 is combined with the nail driving base through an insertion connection, facilitating installation and maintenance. The tail end of the barrel 2 presses against the striking arm 7, and when the barrel 2 is pressed down, it triggers the trigger linkage for firing.

[0044] Refer to Figure 3 , the firing pin 6 is connected to the nail driving base 1 through an insertion connection. The tail end of the firing pin 6 is inserted into one end of the hole of the nail driving base 1 and connected to the nail driving base 1. The tail end of the firing pin 6 is designed as an insertion structure and can be directly inserted into the hole on the nail driving base 1. Through this insertion connection, the firing pin and the nail driving base form a stable combination. The firing pin 6 is not easily detached during the working process, and the installation and disassembly are simplified, and the worn or damaged firing pin 6 can be quickly replaced. The firing pin 6 remains stable during the working process, reducing the vibration or displacement of the firing pin 6 caused by operation, improving the accuracy of nail shooting, reducing the freedom degree of the firing pin 6, and reducing the unstable factors during use. The stable position of the firing pin 6 ensures that the acting force of the firing pin 6 is consistent during each firing, improving the accuracy and consistency of nail shooting, reducing the relative movement between the firing pin 6 and the nail driving base 1, maintaining the stability of firing, and at the same time making the combination of the firing pin 6 and the nail driving base 1 more compact, without increasing additional volume or weight, helping to reduce the total weight of the tool and optimizing the space utilization, and prolonging the service life.

[0045] Refer to Figure 5 , Figure 6 , the barrel 2 is connected to the nail driving base 1 through an insertion connection. The tail end of the barrel 2 is inserted into the other end of the hole of the nail driving base 1 and connected to the nail driving base 1. During the firing process of the nail head body 8, the barrel 2 slides back and forth within the hole of the nail driving base 1. The insertion connection method between the barrel 2 and the nail driving base 1 makes the installation and disassembly process of the barrel 2 simple and fast, improving the use efficiency and maintenance convenience. The barrel 2 slides back and forth within the hole of the nail driving base 1, providing a flexible movement space during the firing process.

[0046] It allows the barrel to adapt to different working requirements in different working stages, improving the operation flexibility and adaptability. It can absorb part of the recoil force, reducing the impact of the recoil force on the nail gun, reducing vibration, improving the accuracy and consistency of nail shooting. The stability and accuracy of nail shooting are significantly improved, reducing the wear on the fixed connection components and extending the service life of the barrel 2 and the nail driving seat 1.

[0047] And by performing cleaning and inspection, the overall performance of the nail gun is improved, and the long-term stability and economy of the tool are enhanced.

[0048] Referring to Figure 6 , the gun head body 8 includes a nozzle 3. The nozzle 3 is provided with an external thread, and the front end of the barrel 2 is provided with a cylindrical internal thread. The external thread of the nozzle 3 is screwed with the cylindrical internal thread at the front end of the barrel 2, which can maintain the tight connection between the nozzle 3 and the barrel 2, reducing the possibility of loosening. The connection structure is stable, convenient for disassembly and maintenance, making the connection between the nozzle 3 and the barrel 2 more universal, adapting to different types of barrels 2 or accessories, and improving the design flexibility and compatibility.

[0049] Referring to Figure 6 , the gun head body 8 includes a striking arm 7. The tail end of the barrel 2 is pressed against the striking arm 7. When the head of the barrel 2 is pressed down, the barrel 2 triggers the trigger linkage of the gun head body 8 to fire a nail.

[0050] When the tail end of the barrel 2 is pressed against the striking arm 7, the striking arm is in a waiting-to-be-activated state. When the head of the barrel 2 is pressed down under the nail driving force, the barrel 2 will trigger the striking arm 7 through the pressure at its front end, thus activating the trigger linkage of the gun head body 8. After the trigger linkage is triggered, it will trigger the nail driving mechanism to complete the nail driving action. It allows the barrel 2 to automatically trigger the nail driving mechanism when subjected to appropriate pressure without additional operation, improving the operation convenience and efficiency, ensuring the stability and reliability of the nail driving action, effectively converting the applied force into a trigger signal, thereby achieving accurate nail driving without complex manual operations, simplifying the operation steps. Since a specific pressure is required to trigger nail driving, it effectively reduces nail driving failures or safety problems caused by improper operation or accidental triggering.

[0051] Referring to Figure 7, the gun head body 8 includes a positioning lock pin 5. An axial U-shaped groove 21 is provided on the circumferential surface of the barrel 2. The positioning lock pin 5 is inserted and installed in the U-shaped groove 21. The positioning lock pin 5 installed on the U-shaped groove 21 restricts the axial sliding stroke of the barrel 2. The insertion design of the functional positioning lock pin 5 in the U-shaped groove 21 restricts the axial sliding range of the barrel 2. The barrel 2 moves within a set range, avoiding exceeding the predetermined sliding stroke, and improving the shooting accuracy and force, enhancing the accuracy and consistency of the nail shooting, improving the overall performance and user experience of the multi-functional nail shooter, and improving the efficiency, stability and durability of the nail shooter. The positioning lock pin 5 is installed on the nail driving base 1. One end of the positioning lock pin 5 radially enters the hole for installing the barrel 2 in the nail driving base 1 inward. An axial U-shaped groove 21 is provided on the circumferential surface of the barrel 2. One end of the positioning lock pin 5 is located in the U-shaped groove 21. When the barrel 2 slides axially, the U-shaped groove 21 slides axially relative to the positioning lock pin 5. The positioning lock pin 5 restricts the circumferential rotation of the barrel 2. The cooperation between the positioning lock pin 5 and the U-shaped groove 21 effectively restricts the circumferential rotation of the barrel 2, ensuring that the barrel remains in a predetermined direction during the nail driving process, avoiding affecting the accuracy or effect of nail driving due to rotation, and maintaining the stability of the barrel in the nail driving base.

[0052] Referring to Figure 8 , the gun head body 8 includes a locking adjustment ring 4. The locking adjustment ring 4 is sleeved on the axial bottom end face of the external thread of the gun nozzle 3. Rotating the gun nozzle 3 axially locks the locking adjustment ring 4 between the axial bottom end face of the external thread of the gun nozzle 3 and the front end face of the barrel 2. The locking adjustment ring 4 controls the force and depth of nail driving. The locking adjustment ring 4 can control the force and depth of nail driving by adjusting the gap between the gun nozzle 3 and the barrel 2, providing higher operation flexibility and precision. The locking adjustment ring 4 can be firmly locked on the axial bottom end face of the external thread of the gun nozzle 3, ensuring the stability of the locking adjustment ring 4 during operation, preventing it from loosening due to vibration or external force, and keeping the set nail driving parameters unchanged. By rotating the gun nozzle 3 to adjust the locking adjustment ring 4, a convenient operation method is achieved, and the force and depth of nail driving can be quickly adjusted without additional tools, allowing precise adjustment of the nail driving parameters within a small range, ensuring that the nail driving effect meets the requirements, and helping to improve the work quality and ensure the consistency of the nail driving effect.

[0057] 4. Force adjustment and stability: The locking adjustment ring 4 is sleeved on the axial bottom end face of the external thread of the nozzle 3. By rotating the adjustment ring 4, the force and depth of nail driving can be controlled, allowing users to make precise adjustments according to different construction requirements, providing higher operation flexibility and accuracy.

[0058] 5. Stability of the firing pin: The firing pin 6 is combined with the nail driving base 1 through an insertion connection, ensuring that the firing pin remains stable during operation, reducing vibration or displacement, improving the accuracy and consistency of nail shooting, extending the service life, and simplifying the installation and disassembly process.

[0059] 6. Trigger mechanism: When the tail end of the barrel 2 presses against the striking arm 7, the downward pressure of the barrel 2 will trigger the trigger linkage of the gun head body 8, thereby initiating the nail driving mechanism. The nail driving is triggered by a specific pressure, improving the operation convenience and efficiency, and ensuring the stability and reliability of nail driving.

[0060] 7. Function of the positioning locking pin: The positioning locking pin 5 is installed on the nail driving base 1 and inserted into the U-shaped groove 21 of the barrel 2, restricting the axial sliding stroke and circumferential rotation of the barrel 2. The barrel remains in a predetermined direction during nail driving, improving the accuracy and consistency of nail driving.

[0061] 8.
