DETAILED DESCRIPTION

[0021] The utility model will be further described in detail below in combination with the drawings and specific embodiment.

[0022] In this embodiment, refer to Figures 1-6A press-in nut with sealing effect, comprising a body 1, a threaded hole 11 is arranged through the center of the body 1, a press-in ring 12 is arranged at one end of the body 1, a recess 13 is arranged at the outer side of the press-in ring 12, a first sealing ring 2 is arranged in the recess 13, detachable sealing blocks 3 are arranged at both ends of the body 1, a bolt column 31 is arranged at one end of the sealing block 3 and cooperates with the threaded hole 11, and a second sealing ring 4 is arranged between the sealing block 3 and the body 1. The press-in ring 12 comprises a boss 121, a fixing block 122 and a plurality of fixing teeth 123, the fixing block 122 is arranged at one end of the boss 121 and extends outward, the plurality of fixing teeth 123 are arranged around the outer side of the boss 121, and a fixing groove is formed between the fixing block 122 and the fixing teeth 123.

[0023] In use, a predetermined mounting hole is first formed on a thin-walled material such as sheet metal, and the material around the mounting hole is plastically deformed through extrusion of a press-in machine, so as to be tightly combined with the fixing block 122 and the fixing teeth 123, thereby forming a firm connection structure. At the same time, the first sealing ring 2 is pressed tightly between the recess 13 and the sheet metal material by the deformed material in the press-in process, thereby effectively preventing moisture, dust and other impurities from penetrating or leaking from the gap of the mounting hole. In addition, the sealing block 3 cooperates with the body 1 by cooperation of the bolt column 31 and the threaded hole 11, so as to press the second sealing ring 4 tightly, thereby achieving a sealing effect. The detachable design enables the user to selectively install or remove the sealing block 3 according to the needs, thereby achieving different sealing effects.

[0024] Moreover, one end of the fixing block 122 is provided with an inclined surface 1221 which is inclined from inside to outside. The arrangement of the inclined surface 1221 makes the fixing groove a kind of gradient structure, which is beneficial to the gradual deformation of the material in the press-in process, so that the press-in process is more smooth, and the contact area between the press-in nut and the sheet metal material is increased, thereby improving the stability and sealing performance of the connection. In addition, the design of the inclined surface 1221 can also guide the flow direction of the material in the press-in process, so as to avoid cracks or breakage of the material in the press-in process, thereby further ensuring the use effect and service life of the press-in nut.

[0025] In this embodiment, the fixing teeth 123 are in triangular structure. The fixing teeth 123 in triangular structure have good stability and shear resistance, which can effectively prevent the press-in nut from loosening or falling off in use. At the same time, the fixing teeth 123 in triangular structure can also increase the friction force between the press-in nut and the sheet metal material, thereby further improving the firmness of the connection. In addition, the fixing teeth 123 in triangular structure also have good self-locking performance, which can maintain the stability of the connection even in harsh environments such as vibration or impact.

[0026] The fixed tooth 123 is a straight tooth or an inclined tooth. The straight tooth and the inclined tooth can increase the meshing area between the rivet nut and the sheet metal material, thereby improving the firmness and stability of the connection. The straight tooth design makes the contact surface between the fixed tooth 123 and the sheet metal material a straight line, which can provide a larger meshing force during the riveting process, thereby improving the strength of the connection. The inclined tooth design can increase the tensile strength of the sheet metal and other thin-walled materials after being attached to the inclined tooth, thereby effectively preventing the rivet nut from loosening due to tension during use. In this embodiment, the straight tooth design makes the rivet nut have higher connection strength and stability during use.

[0027] The threaded hole 11 is provided with a mounting groove 111 at both ends, and the second sealing ring 4 is fixedly installed in the mounting groove 111. The second sealing ring 4 can be stably installed at both ends of the threaded hole 11 through the mounting groove 111, and cooperates with the sealing block 3 or other parts fixed on the body 1, thereby achieving a sealing effect. The rivet nut can maintain good sealing performance in various environments.

[0028] In addition, the outer side of the sealing block 3 is surrounded by a plurality of anti-skid grooves 32. The design of the anti-skid grooves 32 enables the sealing block 3 to be easily operated without using additional tools during installation or disassembly, greatly improving work efficiency. The design of the anti-skid grooves 32 can also increase the friction between the sealing block 3 and the hand, preventing the sealing block 3 from slipping or falling off during assembly or disassembly, further ensuring the safety and reliability of the operation.

[0029] The beneficial effects of the utility model are as follows: through the cooperation of the riveting ring 12 and the first sealing ring 2, the rivet nut can be effectively sealed and connected with the plate or sheet metal and other thin-walled parts during installation, thereby preventing liquid or gas from leaking from the connection. At the same time, through the setting of the detachable sealing block 3 and the second sealing ring 4, the user can install or dismount the sealing block 3 as needed, thereby achieving different sealing effects.

[0030] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model discloses the above preferred embodiment, it is not intended to limit the utility model. Any skilled person in the art can make some changes or modifications within the scope of the utility model technical solution without departing from the utility model technical solution. Any simple modification, equivalent change and modification of the above embodiment within the scope of the utility model technical solution are all within the scope of the utility model technical solution.
