Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a high-sealing bolt. Background Art

[0002] A self-clinching bolt is a fastener that is connected to a part by means of self-clinching. Its main function is to connect two or more parts together and provide stable connection force and sealing performance. Self-clinching bolts are widely used, especially in the fields of aviation, automobiles, and machinery manufacturing. However, in actual use, a gap is easily generated between the screw head of the self-clinching bolt and the part to be connected, resulting in a decrease in the sealing performance of the connection between the self-clinching bolt and the part to be connected, making the self-clinching bolt unsuitable for equipment with high requirements for sealing performance.

[0003] At present, some solutions have been proposed for the sealing performance of rivet bolt connections, but there are still some shortcomings: For example, material improvement: By changing the material of the rivet bolt, the generation of gaps can be reduced and the sealing performance of the connection can be improved. However, the range of material selection is limited, and it is necessary to select materials with better sealing performance under the premise of meeting the connection strength requirements, which puts higher requirements on the research and development of materials; structural design: By changing the structural design of the rivet bolt, the generation of gaps can be reduced and the sealing performance of the connection can be improved. However, the current research on structural design is still relatively limited, and further in-depth research and exploration are needed; process improvement: By improving the connection process of the rivet bolt, the generation of gaps can be reduced and the sealing performance of the connection can be improved. However, the implementation of the process improvement plan needs to take into account the actual production environment and cost factors, and there are certain technical difficulties and economic pressures.

[0004] The inventor proposes a new type of bolt for adapting to equipment with high requirements for sealing performance. Utility Model Content

[0005] The utility model aims to provide a high sealing bolt with reasonable structure, excellent sealing performance and good fastening effect.

[0006] In order to achieve the above utility model purpose, the utility model provides a moisture-proof bolt, comprising:

[0007] A screw body, wherein a screw thread is provided on one side of the screw body;

[0008] a bolt head formed at an end of the screw body and integrally formed with the bolt head; and

[0009] The moisture-proof component includes a water-absorbing gasket, which is sleeved on the outside of the screw body and pressed against the bolt head, and a pressing edge is arranged on the side of the bolt head facing the screw body. The pressing edge squeezes the water-absorbing gasket to achieve the sealing of the bolt.

[0010] A further improvement of the moisture-proof bolt of the utility model lies in that the pressing edge and the screw body are integrally formed.

[0011] A further improvement of the moisture-proof bolt of the utility model lies in that the pressure edge is circumferentially arranged on the bolt head.

[0012] A further improvement of the moisture-proof bolt of the utility model lies in that the thread of the screw body is equidistant thread.

[0013] A further improvement of the moisture-proof bolt of the utility model lies in that the bolt head is in a hexagonal shape.

[0014] The beneficial effects of the utility model are:

[0015] The water-absorbing gasket is sleeved on the outer side of the screw body and pressed against the bolt head. A pressing edge is arranged on the side of the bolt head facing the screw body, and the pressing edge squeezes the water-absorbing gasket to achieve the sealing of the bolt.
