Description

Technical Field

[0001] This utility model relates to the field of nail gun auxiliary structure technology, specifically a nail gun nozzle with a locking structure. Background Technology

[0002] A nail gun is a tool used in construction to nail and install wooden boards. When using a nail gun, the nozzle needs to be installed and matched before use. The nail is driven out through the nozzle. Existing nail gun nozzles are directly installed to the nail gun via a threaded structure, facilitating easy assembly and disassembly. This convenient operation ensures a smooth match between the nozzle and the nail gun, improving the effectiveness of the nail gun.

[0003] A search revealed that patent publication number CN219095048U discloses a nail gun nozzle, comprising a nail gun nozzle body, wherein the nail gun nozzle body is provided with: a disassembly and assembly mechanism, which includes an elastic connecting component and a locking component, and the disassembly and assembly mechanism is disposed on the inner surface of the end of the nail gun nozzle body; and a heat dissipation mechanism, which includes an air jet component, and the heat dissipation mechanism is disposed on the side of the nail gun nozzle body. By designing the disassembly and assembly mechanism, it is possible to easily engage and lock the internal threaded ring, and to install and use the nail gun nozzle body and the end of the nail gun through the internal threaded ring. Furthermore, if frequent disassembly and assembly of the nail gun nozzle body causes damage to the threaded structure, the internal threaded ring can be disassembled in reverse, facilitating the disassembly and replacement of the internal threaded ring. This makes it easy to install the nail gun nozzle body on the end of the nail gun through the internal threaded ring, and reduces the risk of damage to the threaded structure of the nail gun nozzle body rendering it unusable.

[0004] In the actual disassembly and assembly of the internal threaded ring and the nail gun nozzle body, the above-mentioned technical solution requires first removing the fixing bolts connecting the internal threaded ring and the limiting block, and then simultaneously pulling six levers to move the limiting block out of the limiting slot before the internal threaded ring can be removed from the nail gun nozzle body. However, the operator cannot pull all six levers at the same time and needs to use an external workpiece to limit the levers in order to remove the internal threaded ring from the nail gun nozzle body. The disassembly and assembly of the internal threaded ring is cumbersome and inefficient. Therefore, a nail gun nozzle with a locking structure is designed. Utility Model Content

[0005] In view of the defects or shortcomings of nail gun nozzles with locking structures, the purpose of this utility model is to provide a nail gun nozzle with a locking structure, which facilitates the disassembly and assembly of the nozzle body and the internal threaded ring by the workers. The disassembly and assembly are simple and efficient.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] The present invention provides a nail gun nozzle with a locking structure, comprising a nail gun nozzle body, a locking assembly and an internal threaded ring. An internal threaded ring is installed at one end of the nail gun nozzle body, and the nail gun nozzle body and the internal threaded ring are connected by the locking assembly.

[0008] The locking assembly is provided with a mounting post. The end walls at both ends of the mounting post are respectively provided with threaded holes and rectangular slots, and the threaded holes and rectangular slots are connected. A threaded rod is provided in the threaded hole. A connecting shaft is installed at one end of the threaded rod. The other end of the connecting shaft is installed in a bearing on one end wall of the moving block. The moving block is located in the rectangular slot. Both sides of the moving block are provided with pressing blocks. One side of the outer wall of the pressing block is in contact with one side of the outer wall of the moving block. A positioning post is installed on the other side of the outer wall of the pressing block.

[0009] The other end of the positioning post passes through the through hole and is installed in the positioning hole. The positioning hole is opened on the inner wall of the second mounting hole, and the second mounting hole is opened in a ring array on the circumferential outer wall of the internal thread ring.

[0010] The nail gun nozzle body has a first mounting hole arranged in a ring-shaped array on its circumferential outer wall.

[0011] Preferably, the outer wall of the movable block and the wall of the rectangular slot are in clearance fit.

[0012] Limiting blocks are provided on the upper sides of the outer walls of the movable block. The other end of the limiting block is installed in the limiting slot. The outer wall of the limiting block and the wall of the limiting slot are in clearance fit. The limiting slot is opened on both sides of the wall of the rectangular slot.

[0013] Preferably, a rotating plate is installed at the other end of the threaded rod, and the rotating plate is located outside the mounting post.

[0014] Preferably, a spring is sleeved on the outer side of the outer wall of the positioning post, and the spring is located between the outer wall of the extrusion block and the wall of the rectangular slot.

[0015] Preferably, the through holes are formed on both sides of the outer circumferential wall of the mounting post, and the outer wall of the positioning post is clearance-fitted with the wall of the through hole and the wall of the positioning hole.

[0016] Preferably, one end of the mounting post passes through the first mounting hole and is installed in the second mounting hole, and the outer wall of the mounting post is clearance-fitted with the wall of the first mounting hole and the wall of the second mounting hole.

[0017] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0018] 1. In this utility model, through a series of coordinated structural arrangements, when the worker needs to perform the installation operation between the internal threaded ring and the nail gun nozzle body, the worker's rotation of the rotating plate forward or backward will drive the threaded rod to rotate forward or backward. When the threaded rod rotates forward or backward, it will drive the moving block to move in the rectangular slot through the connecting shaft. When the moving block moves towards the opening of the rectangular slot, the moving block will continuously exert a certain squeezing force on the squeezing block. When the squeezing block is subjected to a certain squeezing force, it will compress the spring and cause the squeezing block to move in a certain direction. When the squeezing block moves in a certain direction, it will drive the positioning pin to move in a certain direction. When the positioning pin moves into the positioning hole, the connection between the nail gun nozzle body, the locking assembly and the internal threaded ring is completed.

[0019] 2. In this utility model, through a series of coordinated structural arrangements, when the worker needs to disassemble the internal threaded ring from the nail gun nozzle body, the worker rotates the rotating plate clockwise or counterclockwise and indirectly drives the extrusion block to move towards the end wall of one end of the rectangular slot. This reduces the force caused by the spring indirectly connected to the extrusion block. At this time, under the action of the spring rebound, the positioning pin will move out of the positioning hole. When the positioning pin moves out of the positioning hole, the worker can remove the locking assembly from the nail gun nozzle body and the internal threaded ring. After the four locking assemblies are disassembled, the worker can remove the internal threaded ring from the nail gun nozzle body.

[0020] Therefore, as can be seen from the above, compared with the existing technology, this utility model facilitates the disassembly and assembly of the gun nozzle body and the internal threaded ring by the staff, and the disassembly and assembly are simple and efficient.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] like Figure 1-4 As shown, a nail gun nozzle with a locking structure includes a nail gun nozzle body 100, a locking assembly 200 and an internal threaded ring 300. The internal threaded ring 300 is installed at one end of the inside of the nail gun nozzle body 100, and the nail gun nozzle body 100 and the internal threaded ring 300 are connected by the locking assembly 200.

[0034] The locking assembly 200 is provided with a mounting post 220. The end walls of the mounting post 220 are respectively provided with threaded holes 221 and rectangular slots 222, and the threaded holes 221 and rectangular slots 222 are connected. A threaded rod 210 is provided in the threaded hole 221, and the threaded rod 210 is threadedly connected to the threaded hole 221. The threaded rod 210 rotates forward or backward, which will indirectly drive the pressing block 240 to move in a certain direction. A connecting shaft 212 is installed at one end of the threaded rod 210, and the other end of the connecting shaft 212 is installed in a bearing on one end wall of the moving block 230. The moving block 230 is located in the rectangular slot 222. Pressing blocks 240 are provided on both sides of the moving block 230, and one side outer wall of the pressing block 240 is in contact with one side outer wall of the moving block 230. A positioning post 241 is installed on the other side outer wall of the pressing block 240.

[0035] The other end of the positioning pin 241 passes through the through hole 223 and is installed in the positioning hole 320. The positioning hole 320 is opened on the inner wall of the second mounting hole 310. The second mounting holes 310 are arranged in a ring array on the circumferential outer wall of the internal thread ring 300.

[0036] The nail gun nozzle body 100 has first mounting holes 110 arranged in a ring array on its circumferential outer wall.

[0037] The outer wall of the movable block 230 and the wall of the rectangular slot 222 are in clearance fit. Because the outer wall of the movable block 230 and the wall of the rectangular slot 222 are in clearance fit, the movement of the movable block 230 can be limited and guided.

[0038] Limiting blocks 231 are provided on the upper part of the outer walls on both sides of the movable block 230. The other end of the limiting block 231 is installed in the limiting slot 224, and the outer wall of the limiting block 231 and the hole wall of the limiting slot 224 are in clearance fit. The limiting slot 224 is opened on both sides of the hole wall of the rectangular slot 222. The matching of the limiting block 231 and the limiting slot 224 can further play a role in limiting and guiding the movement of the movable block 230.

[0039] A rotating plate 211 is mounted on the other end of the threaded rod 210, and the rotating plate 211 is located outside the mounting post 220.

[0040] A spring 250 is sleeved on the outer side of the outer wall of the positioning post 241, and the spring 250 is located between the outer wall of the extrusion block 240 and the wall of the rectangular slot 222.

[0041] Through holes 223 are formed on both sides of the outer circumferential wall of the mounting post 220. The outer wall of the positioning post 241 is clearance-fitted with the wall of the through hole 223 and the wall of the positioning hole 320. Because the outer wall of the positioning post 241 is clearance-fitted with the wall of the through hole 223, it can limit and guide the movement of the positioning post 241. Because the outer wall of the positioning post 241 is clearance-fitted with the wall of the positioning hole 320, it is easy to install the positioning post 241 into the positioning hole 320 or to remove the positioning post 241 from the positioning hole 320.

[0042] One end of the mounting post 220 passes through the first mounting hole 110 and is installed in the second mounting hole 310. The outer wall of the mounting post 220 is clearance-fitted with the hole wall of the first mounting hole 110 and the hole wall of the second mounting hole 310. Because the outer wall of the mounting post 220 is clearance-fitted with the hole wall of the first mounting hole 110 and the hole wall of the second mounting hole 310, it is convenient to install the mounting post 220 into the first mounting hole 110 and the second mounting hole 310 or to remove the mounting post 220 from the first mounting hole 110 and the second mounting hole 310.

[0043] Working principle: When the operator needs to install the internal threaded ring 300 and the nail gun nozzle body 100, rotating the rotating plate 211 clockwise or counterclockwise will drive the threaded rod 210 to rotate clockwise or counterclockwise. The threaded rod 210, in turn, will drive the moving block 230 to move within the rectangular slot 222 via the connecting shaft 212. As the moving block 230 moves towards the opening of the rectangular slot 222, it continuously exerts a certain compressive force on the pressing block 240. This compressive force compresses the spring 250, causing the pressing block 240 to move in a certain direction. This movement of the pressing block 240 in that direction will drive the positioning pin 241 to move in that direction. When the positioning pin 241 moves into the positioning hole 320, the connection between the nail gun nozzle body 100, the locking assembly 200, and the internal threaded ring 300 is completed. Next, when the operator needs to disassemble the internal threaded ring 300 from the nail gun nozzle body 100, the operator rotates the rotating plate 211 clockwise or counterclockwise, indirectly moving the pressing block 240 towards the end wall of one end of the rectangular slot 222. This reduces the force caused by the spring 250 indirectly connected to the pressing block 240. At this time, under the action of the spring 250's rebound, the positioning pin 241 will move out of the positioning hole 320. When the positioning pin 241 moves out of the positioning hole 320, the operator can remove the locking assembly 200 from the nail gun nozzle body 100 and the internal threaded ring 300. After the four locking assemblies 200 are removed, the operator can remove the internal threaded ring 300 from the nail gun nozzle body 100. Therefore, compared with the existing technology, this utility model facilitates the operator's disassembly and assembly operations between the nail gun nozzle body and the internal threaded ring 300, making disassembly and assembly simple and efficient.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
