Description

Technical Field

[0001] This utility model relates to the technical field of rivet nuts with a flower-shaped design, specifically a rivet nut with a high load-bearing capacity. Background Technology

[0002] A riveting nut is a fastener used to fix and connect thin sheet materials. It is commonly used for connecting thin metal sheets. Its working principle is to fix the nut to the thin sheet by riveting to form a strong connection. Riveting nuts are easy to install, simple to operate, and have high connection strength. Therefore, riveting nuts are gradually being widely used.

[0003] During riveting, heavy loads need to be borne. However, most openwork rivet nuts have an upper limit to their hardness. Therefore, if their load-bearing capacity is insufficient, they are prone to direct damage during the riveting process, affecting the riveting effect. Utility Model Content

[0004] The purpose of this utility model is to provide a high-load-bearing rivet nut to solve the problem mentioned in the background art that when riveting, it is necessary to bear a heavy load, but most rivet nuts have an upper limit to their hardness. Therefore, if their load-bearing capacity is insufficient, the rivet nut is easily damaged during the riveting process, affecting the riveting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flower-shaped rivet nut with load-bearing capacity, comprising a flower-shaped rivet nut body and a base, wherein a reinforcing plate is fixed at a lower position on the outside of the flower-shaped rivet nut body, an inner hole is formed inside the flower-shaped rivet nut body, and a wall-breaking groove is provided at a lower position inside the flower-shaped rivet nut body.

[0006] As a further technical solution of this utility model, the wall-breaking grooves are distributed in a ring around the center of the rivet nut body, and the reinforcing plates are distributed in a circular ring around the rivet nut body.

[0007] As a further technical solution of this utility model, the bottom of the reinforcing plate is fixed to the bottom surface of the chassis, and the side of the reinforcing plate is fixed to the outer wall surface of the main body of the flower rivet nut.

[0008] As a further technical solution of this utility model, the position of the wall-breaking groove can be torn into a trumpet shape, and a deformation zone is formed on the outer wall of the main body of the flower rivet nut between the wall-breaking grooves.

[0009] As a further technical solution of this utility model, the outer part of the main body of the flower rivet nut is coated with a protective layer, which includes a wear-resistant layer and an anti-corrosion layer.

[0010] As a further technical solution of this utility model, the anti-corrosion layer is coated on the outer wall of the main body of the flower rivet nut, and the outer wall of the anti-corrosion layer is coated with a wear-resistant layer.

[0011] As a further technical solution of this utility model, the wear-resistant layer and the anti-corrosion layer have the same coating surface area, and the middle part of the main body of the flower rivet nut is filled with a second solid layer.

[0012] As a further technical solution of this utility model, the main body of the flower rivet nut is filled with a first solid layer at the position outside the second solid layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the bearing capacity of this type of flower-shaped rivet nut not only improves the bearing capacity, but also improves the external protection capability and filling strength of the flower-shaped rivet nut.

[0014] (1) By using a reinforcing plate to connect the main body of the flower rivet nut and the chassis, the connection is reinforced. The lower part of the main body of the flower rivet nut has a wall-breaking groove. The wall-breaking groove is formed by cold heading or machining. A deformation zone is formed on the outside of the flower rivet nut body between the wall-breaking grooves. The riveting deformation teares the wall-breaking groove, thereby reducing the force. The deformation is completed in the deformation zone and finally becomes a trumpet shape. This can avoid the limitation of the hardness of the parts due to riveting and improve the hardness and load-bearing capacity of the parts.

[0015] (2) A protective layer is coated on the outside of the flower rivet nut body. The protective layer is composed of a wear-resistant layer and an anti-corrosion layer. The anti-corrosion layer is coated on the outer wall of the flower rivet nut body to form anti-corrosion protection. The outer wall of the anti-corrosion layer is coated with a wear-resistant layer. Therefore, the wear-resistant layer plays a certain role in wear-resistant protection, thereby improving a certain external protection capability.

[0016] (3) By filling the center of the rivet nut body with the second solid layer, and then distributing the first solid layer inside and outside the second solid layer, the filling strength is improved after the first solid layer and the second solid layer are distributed, thereby improving the service life.

[0023] Please see Figure 1-4 An embodiment of this utility model is provided: a flower-shaped rivet nut with load-bearing capacity, including a flower-shaped rivet nut body 1 and a base plate 3. A reinforcing plate 4 is fixed at the lower position of the outer side of the flower-shaped rivet nut body 1. An inner hole 5 is formed inside the flower-shaped rivet nut body 1. A wall-breaking groove 2 is opened at the lower position inside the flower-shaped rivet nut body 1.

[0024] As a further technical solution of this utility model, the wall-breaking groove 2 is distributed in a ring around the center of the flower rivet nut body 1, and the reinforcing plate 4 is distributed in a circular ring around the flower rivet nut body 1.

[0025] As a further technical solution of this utility model, the bottom of the reinforcing plate 4 is fixed to the bottom surface of the chassis 3, and the side of the reinforcing plate 4 is fixed to the outer wall surface of the flower rivet nut body 1.

[0026] As a further technical solution of this utility model, the position of the wall-breaking groove 2 can be torn into a trumpet shape, and a deformation zone 11 is formed on the outer wall of the flower rivet nut body 1 between the wall-breaking grooves 2.

[0027] As a further technical solution of this utility model, the outer part of the rivet nut body 1 is coated with a protective layer 6, which includes a wear-resistant layer 7 and an anti-corrosion layer 8.

[0028] As a further technical solution of this utility model, the anti-corrosion layer 8 is coated on the outer wall of the main body 1 of the flower rivet nut, and the outer wall of the anti-corrosion layer 8 is coated with a wear-resistant layer 7.

[0030] As a further technical solution of this utility model, the main body 1 of the flower rivet nut is filled with a first solid layer 9 located outside the second solid layer 10;

[0031] Further, through cold heading or machining processes, the wall-breaking groove 2 is formed, and a deformation zone 11 is formed on the outside of the main body 1 of the flower rivet nut at the position between the wall-breaking grooves 2. Therefore, when the wall-breaking groove 2 is torn under pressure, the deformation zone 11 will undergo extrusion deformation accordingly.

A deformation zone 11 is formed on the outside of the rivet nut body 1 between the wall-breaking grooves 2. The rivet deformation breaks the wall-breaking groove 2, which reduces the force. The deformation is completed at the deformation zone 11 and finally becomes a trumpet shape, which improves the load-bearing capacity.
