Description

Technical Field

[0001] The utility model relates to the technical field of wood product processing, in particular to a special rivet for wood products. Background Art

[0002] A rivet is a part that is fixed by moving the rivet cap through external force, causing the metal rivet sleeve on the outside to deform. Due to its effective and stable connection, it is widely used in various fixing environments.

[0003] During the processing and fixing of wooden products, unlike metal materials, the strength of wooden products themselves is relatively low, and the weathered wooden products are relatively brittle. As a result, during the riveting process, the connection area may be broken due to excessive force applied by the rivet gun, which may lead to connection collapse or even connection failure. This will affect the connection effect as well as the aesthetics, so there is room for improvement. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a special rivet for wooden products, which can control the fixing distance to avoid damage to the wooden products.

[0010] As a further improvement of the present invention, one end of the rivet head close to the rivet body forms a second fastening surface.

[0011] As a further improvement of the present invention, both the first fastening surface and the second fastening surface are planes.

[0012] As a further improvement of the present invention, the limiting segment includes two symmetrically arranged guiding segments, the ends of the two guiding segments are connected to each other and are used to guide the limiting segment to deform in a direction away from the rivet body.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0019] like Figure 1 As shown, a special rivet for wood products includes a rivet body 1 and a rivet sleeve 2. The rivet sleeve 2 includes a deformation section 3 and a limiting section 4 connected to each other. The limiting section 4 is provided with a first fastening surface 5 at one end away from the deformation section 3. One end of the rivet body 1 passes through the deformation section 3 and the limiting section 4 respectively to form an operating end 6. The end of the rivet body 1 away from the operating end 6 is provided with a rivet head 7. The operating end 6 is used to drive the rivet body 1 to move along the rivet sleeve 2 so that the rivet head 7 squeezes the deformation section 3. After deformation, the deformation section 3 forms a fastening interval with the first fastening surface 5. The limiting section 4 is used to abut the rivet head 7 to limit the moving range of the rivet head 7.

[0020] The limiting effect of the limiting section 4 on the rivet head 7 allows the limiting section 4 to serve as the minimum fixing range to complete the connection and fixation of the wooden product, thereby avoiding damage and collapse of the wooden product surface caused by excessive movement of the rivet head 7. At the same time, the overall structure is simple and the processing difficulty is low.

[0021] Preferably, the limiting section 4 is threadedly connected to the rivet body 1 .

[0022] The threaded connection between the limiting section 4 and the rivet body 1 allows the rivet body 1 to be fixed to the limiting section 4 after the rivet body 1 is cut, thereby further improving the stability of the fixation.

[0023] At the same time, due to the threaded connection between the limiting section 4 and the rivet body 1 , the rivet body 1 can be moved manually to adapt to different operating environments.

[0024] Preferably, a surface of the first fastening surface 5 close to the deformation section 3 is provided with anti-slip stripes.

[0025] The provision of the anti-slip stripes can ensure the stability of the first fastening surface 5 and the material before and after fixation.

[0026] Since wooden products are mostly household items or toys, in order to improve safety, the rivet head 7 includes a spherical extrusion portion 8, and an umbrella-shaped protective surface 9 is formed at one end of the extrusion portion 8 away from the rivet body 1. A storage area 10 is formed between the protective surface 9 and the extrusion portion 8, and the deformation section 3 is stored in the storage area 10 after deformation.

[0027] The spherical extrusion portion 8 can be adapted to the threaded connection of the rivet rod to facilitate the application of force to the deformation section 3. At the same time, the deformation section 3 can be accommodated by setting the storage interval 10, thereby ensuring that both the inner and outer sides form a flat or curved surface after the fixation is completed, reducing the damage caused by bumps to ensure safety.

[0028] Preferably, one end of the rivet head 7 close to the rivet body 1 forms a second fastening surface 11 .

[0029] The second fastening surface 11 can be provided to make the force applied by the extrusion portion 8 more uniform, so that when the thickness of the fixed position exceeds the length of the limiting section 4, the risk of wood damage can be reduced by the second fastening surface 11.

[0030] Preferably, the first fastening surface 5 and the second fastening surface 11 are both planes.

[0031] Since the thinner deformation section 3 forms a gap between the deformation section 3 and the rivet body 1, when the deformation section 3 is subjected to force, the gap will cause the deformation direction of the deformation section 3 to be uncertain, and then when the deformation section 3 is deformed inward, it is easy to cause the failure of the overall structure. Therefore, in order to ensure that the deformation direction of the deformation section 3 is fixed, the limiting section 4 includes two symmetrically arranged guide sections 15, the ends of the two guide sections 15 are connected to each other and are used to guide the limiting section 4 to deform in a direction away from the rivet body 1.

[0032] Specifically, in this embodiment, the guide section 15 is arc-shaped, and one end of the two arc-shaped guide sections 15 is bent away from the rivet body 1 and connected to each other, so that when the guide sections 15 are subjected to force, their deformation direction can be guaranteed to be determined.

[0033] Preferably, a breaking notch 12 is formed on the rivet body 1 .

[0034] The provision of the breaking notch 12 can facilitate breaking the rivet body 1 after installation, thereby avoiding potential safety hazards caused by the excess exposure of the rivet body 1, and can also make the overall structure more streamlined.

[0035] Preferably, the rivet body 1 includes a connecting portion 13 , the connecting portion 13 is threadedly connected to the limiting segment 4 , the connecting portion 13 includes two thread segments 14 , and the breaking notch 12 is provided between the two thread segments 14 .

[0036] The breaking notch 12 is arranged between the two threaded sections 14 so that the operator can conveniently observe the position of the rivet body 1 when performing manual operation. That is, when the breaking notch 12 is located at the end of the limiting section 4, the rivet head 7 is in conflict with the limiting section 4, so that the excess rivet body 1 can be separated through the breaking notch 12.

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
