Description

Technical Field

[0001] This utility model relates to the field of nail shooting technology, specifically to a fixed pointed threaded nail. Background Technology

[0002] Threaded nails are a special type of nail, characterized by a threaded structure on their surface. Typically made of metal, threaded nails offer superior fixing power and stability compared to ordinary nails. When used, they are driven quickly into an object using a nail gun or similar tool. The threads increase the contact area and friction with the object, resulting in a more secure fixation. In construction, threaded nails are commonly used to secure materials such as wood panels and metal sheets to concrete or other rigid substrates.

[0003] A search revealed that Chinese Patent CN222141736U discloses a self-fixing pointed threaded nail, comprising a nail body with threads on its outer side, a pointed block fixedly connected to one end of the nail body, two limiting grooves on the outer side of the pointed block, a washer fitted around the pointed block, multiple guide plates fixedly connected to the outer periphery of the washer, two limiting blocks fixedly connected to the inner side of the washer, a tail end block fixedly connected to the other end of the nail body, and an impact ring fixedly connected to the outer side of the tail end block. In this invention, the cooperation of the limiting blocks and limiting grooves allows the washer to be more stably fitted around the outer periphery of the pointed block. The washer acts as a buffer and provides a sealing effect after firing. The guide plates contact the nail gun's bore, providing a limiting effect and ensuring the stability of the nail body during firing.

[0004] Existing devices have some drawbacks in use. For example, traditional nails mainly rely on the friction between the nail body and the target object, as well as the physical obstruction formed by the nail body inside the target object, to achieve fixation. However, when faced with some special working conditions or high-intensity usage requirements, this single fixing method is often difficult to meet the actual needs. For example, in application scenarios that are subjected to large external forces, vibration environments, or require long-term maintenance of high-strength connections, traditional nails are prone to loosening and falling off, leading to connection failure and thus affecting the safety and reliability of the entire structure. Utility Model Content

[0005] The purpose of this invention is to provide a fixed pointed threaded nail, which solves the problems of loosening and falling off of traditional nails, leading to connection failure.

[0006] This utility model provides the following technical solution: a fixed pointed threaded nail, including a nail, the bottom of the nail having a plurality of through holes arranged in a ring array, the nail having a vertically arranged receiving cavity inside the nail, the receiving cavity communicating with the through holes, each of the plurality of through holes being provided with an auxiliary fixing component, the receiving cavity being provided with a driving component for driving the auxiliary fixing component, and a plastic positioning ring being fixedly sleeved on the bottom of the nail.

[0007] As a preferred embodiment of the above technical solution, the auxiliary fixing component includes a fixing plate fixedly connected to the inner wall of the through hole, a positioning pin being disposed through the fixing plate, the positioning pin sliding on the fixing plate, a movable extrusion plate being fixedly sleeved on the outer wall of the receiving cavity near the positioning pin, and a return spring being disposed between the movable extrusion plate and the fixing plate.

[0008] As a preferred embodiment of the above technical solution, the driving assembly includes a fixing ring fixed to the top of the receiving cavity, a driving rod inserted at the center of the fixing ring, the outer wall of the top of the driving rod being threadedly connected to the inner wall of the fixing ring, and the bottom end of the driving rod abutting against the end of the positioning pin.

[0009] As a preferred embodiment of the above technical solution, a limiting groove is provided on the inner walls of the two opposite sides of the through hole, and a slider is slidably connected in the limiting groove. The ends of the two sliders are fixed to the outer wall of the movable extrusion plate.

[0010] As a preferred embodiment of the above technical solution, the reset spring is wound around the outside of the positioning pin, one end of the reset spring is fixed to the fixing plate, and the other end of the reset spring is fixed to the side wall of the moving pressing plate.

[0011] As a preferred embodiment of the above technical solution, a cross groove is provided at the top end of the drive rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a plastic positioning ring is used to fix the nail body inside the barrel of a nail gun to prevent lateral deviation during firing. When the fixed-tip threaded nail is driven into the target object by the nail gun, an auxiliary fixing component is inserted into the interior of the target object by a drive component. These auxiliary fixing components form a fixed connection with the target object from different directions, increasing the contact area and action point between the nail and the target object, and greatly improving the fixing strength and stability between the nail and the target object. When it is necessary to remove the nail, simply remove the drive rod, so that the elastic force of the return spring is further released, and the moving compression plate drives the positioning nail away from the target object. Thus, the positioning nail no longer has the function of fixing the nail to the target object, making it easy to remove the nail. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a fixed pointed threaded nail, including a nail 1. Multiple through holes 11 are arranged in a circular array at the bottom of the nail 1. A receiving cavity 12 is vertically formed inside the nail 1, communicating with the through holes 11. An auxiliary fixing component 2 is provided in each of the multiple through holes 11. A driving component 3 for driving the auxiliary fixing component 2 is provided in the receiving cavity 12. A plastic positioning ring 13 is fixedly sleeved on the bottom of the nail 1. In specific use, the plastic positioning ring 13 is used to fix the nail body inside the barrel of the nail gun to prevent lateral deviation during firing. When the fixed pointed threaded nail 1 is fired into a target object using the nail gun, the driving component 3 drives the auxiliary fixing component 2 to insert into the interior of the target object. Through the synergistic effect of the auxiliary fixing component 2 and the driving component 3, the fixing strength and stability between the nail 1 and the target object are greatly improved.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the auxiliary fixing assembly 2 includes a fixing plate 21 fixedly connected to the inner wall of the through hole 11. A positioning pin 22 is disposed through the fixing plate 21 and slides on the fixing plate 21. A movable pressing plate 23 is fixedly sleeved on the positioning pin 22 near the outer wall of the receiving cavity 12. A return spring 24 is disposed between the movable pressing plate 23 and the fixing plate 21. The return spring 24 is wrapped around the outside of the positioning pin 22. One end of the return spring 24 is fixed to the fixing plate 21, and the other end of the return spring 24 is fixed to the side wall of the movable pressing plate 23, thereby preventing... The return spring 24 shifts during compression and extension. The drive assembly 3 includes a fixing ring 31 fixed to the top of the receiving cavity 12. A drive rod 32 is inserted into the center of the fixing ring 31. The outer wall of the top of the drive rod 32 is threaded to the inner wall of the fixing ring 31. The bottom end of the drive rod 32 abuts against the end of the positioning pin 22. A cross groove 321 is formed at the top of the drive rod 32. In actual use, when no item is fixed, the return spring 24 is in a naturally extended state, and a certain distance is maintained between the moving compression plate 23 and the fixing plate 21. The positioning pin 22... Also located within the through hole 11, the drive rod 32 is then vertically inserted downwards into the receiving cavity 12. After the drive rod 32 is inserted to a certain position, a screwdriver is inserted into the cross groove 321 to rotate the drive rod 32, thereby causing the drive rod 32 to screw into the fixing ring 31. Then, the bottom of the drive rod 32 presses and pushes the positioning pin 22, causing the positioning pin 22 to slide outwards along the fixing plate 21. As the positioning pin 22 moves, the moving pressing plate 23 also moves outwards towards the target object and applies pressure to the object. At the same time, the return spring 24 is compressed, storing elastic potential energy. When the pressure of the moving positioning pin 22 on the target object reaches a certain level, it can further and stably fix the nail 1 to the target object. When it is necessary to remove the nail 1, simply remove the drive rod 32. In this way, the elastic force of the return spring 24 is further released, and the moving pressing plate 23 drives the positioning pin 22 away from the target object. Thus, the positioning pin 22 no longer has the function of fixing the nail 1 to the target object, making it easy to remove the nail 1.

[0023] As one implementation method in this embodiment, such as Figure 4 As shown, limit grooves 41 are provided on the inner walls of the two opposite sides of the through hole 11. Slider 42 is slidably connected in the limit grooves 41. The ends of the two sliders 42 are fixed to the outer wall of the movable extrusion plate 23. In actual use, the sliders 42 fixed to the movable extrusion plate 23 slide in the limit grooves 41 to ensure that the moving direction of the movable extrusion plate 23 remains stable and there will be no deviation or shaking.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
