The hollow shock absorption and noise reduction nail structure comprises a nail body, an inner cavity is formed in the nail body, and a nail cap is installed at the tail of the nail body in a sliding connection mode.

A plurality of annularly-distributed inserting pieces are fixedly embedded in the inner wall of the nail cap. According to the hollow shock-absorbing and noise-reducing nail structure, the nail cap is knocked by a hammer, so that the inserting column slides along the inner cavity and tightly compresses the metal sand, and the metal sand can be plastically deformed to absorb vibration energy, so that the metal sand on the two sides of the steel ball can be deformed and the impact amplitude on the steel ball is reduced; therefore, internal stress generated when the nail body is impacted is effectively reduced, and the effect of reducing noise generated when the nail body is knocked by a hammer is achieved.

Description

Technical Field

[0001] This utility model relates to the field of noise reduction nail technology, and in particular to a hollow shock absorption and noise reduction nail structure. Background Technology

[0002] In traditional nail applications, especially in the fields of construction, carpentry, and decoration, nails are widely used as connectors. However, traditional nails generate significant vibration and noise during hammering, which not only affects the comfort of the construction environment but may also pose potential hazards to the surrounding environment and the hearing of operators. In addition, when traditional nails are subjected to impact, the lack of an effective shock absorption mechanism often leads to significant internal stress in the nail body or the connected material, thereby affecting the connection strength and durability.

[0003] To address these issues, some nail products with vibration and noise reduction functions have emerged on the market. However, most of these products are complex in structure, expensive, and their performance in practical applications is not ideal. For example, some products reduce vibration and noise by adding a layer of elastic material, but this method often sacrifices the connection strength of the nail; other products attempt to reduce noise by changing the shape or material of the nail, but the effect is limited and it is difficult to simultaneously meet the dual needs of vibration reduction and noise reduction.

[0004] Therefore, it is necessary to provide a new hollow vibration damping and noise reduction nail structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hollow shock-absorbing and noise-reducing nail structure.

[0006] The hollow shock-absorbing and noise-reducing nail structure provided by this utility model includes a nail body, an inner cavity is provided inside the nail body, and a nail cap that is slidably connected is installed at the tail of the nail body.

[0007] The inner cavity of the nail body is filled with metal sand and steel balls are placed therein, with the metal sand distributed in the inner cavities on both sides of the steel balls.

[0008] The tail of the nail body is provided with a protrusion, and the protrusion is provided with a plurality of annularly distributed external oblique insertion cavities.

[0009] The inner wall of the nail head is fixedly fitted with multiple ring-shaped insert pieces, and each insert piece corresponds to an externally inclined insert cavity.

[0010] Preferably, the diameter of the steel ball is the same as the inner diameter of the inner cavity.

[0011] Preferably, a coaxially arranged insertion post is fixedly installed on the inner wall of the nail head, and the insertion post is inserted into the inner cavity of the nail body.

[0012] Preferably, the diameter of the insertion end of the insertion post is larger than the diameter of the cavity at the tail of the nail body.

[0013] Preferably, a rubber pad is fixedly fitted into the bottom wall of the inner cavity of the nail body.

[0014] Compared with related technologies, the hollow shock-absorbing and noise-reducing nail structure provided by this utility model has the following beneficial effects:

[0015] This invention utilizes a hammer to strike the nail head, thereby causing the inserted post to slide along the inner cavity and tightly compress the metal sand. Since the metal sand can undergo plastic deformation to absorb vibration energy, the metal sand on both sides of the steel ball will deform and impact the steel ball, thus effectively reducing the internal stress generated by the impact on the nail body and reducing the noise generated when the hammer strikes the nail body.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 3 The present invention provides a hollow shock-absorbing and noise-reducing nail structure, which includes a nail body 1, a nail head 2, metal sand 3, and steel balls 4.

[0023] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3The nail body 1 has an inner cavity 1a, and a nail head 2 is slidably connected to the tail of the nail body 1. A coaxial insertion post 21 is fixedly installed on the inner wall of the nail head 2, and the insertion post 21 is inserted into the inner cavity 1a of the nail body 1. The inner cavity 1a of the nail body 1 is filled with metal sand 3 and steel balls 4 are placed therein. The metal sand 3 is distributed in the inner cavities 1a on both sides of the steel balls 4.

[0024] It should be noted that when using nail body 1, the nail head on nail body 1 should be facing the object (such as a wall, wooden block, etc.), and then the nail head 2 should be struck with a hammer. This causes the inserted post 21 to slide along the inner cavity 1a and tightly compress the metal sand 3. Since the metal sand 3 can undergo plastic deformation to absorb vibration energy, the metal sand 3 on both sides of the steel ball 4 will deform and impact the steel ball 4. Therefore, the internal stress generated by the impact on nail body 1 is effectively reduced, and the noise generated when the hammer strikes nail body 1 is reduced.

[0025] The bottom wall of the inner cavity 1a of the nail body 1 is fixedly fitted with a rubber pad 5. The rubber pad 5 further effectively reduces the internal stress of the nail body 1 when it is subjected to impact.

[0026] The diameter of the steel ball 4 is the same as the inner diameter of the inner cavity 1a, which allows the steel ball 4 to slide along the inner cavity 1a, and the metal sand 3 on the inner side is effectively compacted.

[0027] The insertion end diameter of the insertion post 21 is larger than the diameter of the tail cavity of the nail body 1, thereby preventing the insertion post 21 from slipping out of the tail cavity 1a of the nail body 1.

[0028] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 The tail of the nail body 1 is provided with a protrusion 11, and the protrusion 11 has multiple annularly distributed oblique insertion cavities 11a. The inner wall of the nail head 2 is fixedly fitted with multiple annularly distributed insertion pieces 6, and the insertion pieces 6 correspond one-to-one with the oblique insertion cavities 11a.

[0029] It should be noted that when the hammer is used to strike the nail head 2 to drive the insertion post 21 to slide along the inner cavity 1a, the insertion piece 6 slides along the outer inclined insertion cavity 11a. Since the outer inclined insertion cavity 11a is a sliding cavity when tilted, the insertion piece 6 bends outward while sliding along the outer inclined insertion cavity 11a, so that the nail head 2 can be stably fixed to the nail body 1, thereby enhancing the overall stability of the nail.

[0030] The working principle of the hollow shock-absorbing and noise-reducing nail structure provided by this utility model is as follows:

[0031] When using nail body 1, the nail head on nail body 1 is positioned facing the object (such as a wall, wooden block, etc.). Then, the nail head 2 is struck with a hammer, causing the insertion post 21 to slide along the inner cavity 1a and tightly compress the metal sand 3. Since the metal sand 3 can undergo plastic deformation to absorb vibration energy, the metal sand 3 on both sides of the steel ball 4 will deform and impact the steel ball 4. This effectively reduces the internal stress generated by the impact on nail body 1 and reduces the noise generated when the hammer strikes nail body 1. When the hammer strikes nail head 2 to drive insertion post 21 to slide along inner cavity 1a, insertion piece 6 slides along the outer inclined insertion cavity 11a. Since the outer inclined insertion cavity 11a is a sliding cavity when tilted, insertion piece 6 bends outward while sliding along the outer inclined insertion cavity 11a, so that nail head 2 can be stably fixed to nail body 1, enhancing the overall stability of the nail.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
