[0006] Through the above scheme, the press rivet screw realizes lightweight design in structural design, while maintaining sufficient strength and connection performance. The hexagonal rod head is convenient for operation with tools, the flange surface provides a larger contact area to disperse pressure and prevent deformation of the material during fastening, the design of the conical head enables the screw to more effectively disperse stress during the press riveting process, improves the reliability of the connection, and in addition, the cooperation of the helical line of the screw rod and the top rod ensures the accuracy and stability of the screw when being pressed into the material. The press rivet screw meets the lightweight requirement while ensuring the convenience of installation and the firmness of the connection.

[0007] Further, an inner hexagonal groove is formed on the left side surface of the hexagonal rod head.

[0008] Through the above scheme, the design of the inner hexagonal groove enables better gripping force when operating with tools such as wrenches, thereby improving the convenience and accuracy of operation. In addition, the combination of the inner hexagonal groove and the hexagonal rod head further enhances the torsional resistance of the press rivet screw, ensuring that the screw will not easily slip or be damaged when subjected to a large torque.

[0009] Further, the outer surface of the top rod is sleeved with a protective pad, and the left side of the protective pad is fixedly connected with the right side of the hexagonal rod head.

[0010] Through the above scheme, through the setting of the protective pad, not only the top rod can be protected from damage in the process of pressure riveting, but also the impact force applied on the screw can be absorbed and dispersed to some extent, thereby prolonging the service life of the screw. In addition, the fixed connection of the protective pad and the hexagonal rod head ensures that the protective pad will not fall off during operation, maintaining the stability and safety of operation.

[0011] Further, the outer surface of the conical head is provided with a plurality of expansion grooves.

[0012] Through the above scheme, through the design of the plurality of expansion grooves of the conical head, the pressure can be effectively dispersed and stress concentration can be reduced in the process of pressure riveting, thereby improving the compression strength and durability of the screw.

[0013] Further, the screw rod is composed of stainless steel material.

[0014] Through the above scheme, through the selection of stainless steel material, not only the overall corrosion resistance of the screw is improved, but also the use stability of the screw in harsh environment is enhanced. In addition, the high strength characteristics of the stainless steel material enable the screw to maintain good structural integrity when bearing large tension or pressure, thereby ensuring the reliability of the connection.

[0015] Further, the outer surface of the top rod is fixedly connected with a ground glass sleeve, and the outer surface of the ground glass sleeve is in contact with the inner wall of the screw rod.

[0016] Through the above scheme, through the setting of the ground glass sleeve, not only the friction between the top rod and the screw rod is increased, thereby improving the stability and accuracy during operation, but also the special treatment of the ground glass surface can effectively prevent damage caused by sliding during pressure riveting.

[0017] Further, the inside of the spiral line is fixedly embedded with a rubber ring.

[0018] Through the above scheme, through the use of the rubber ring, not only can the vibration be effectively absorbed and the noise be reduced, but also when the screw and the screw hole are matched, an additional sealing effect can be provided to prevent leakage of liquid or gas.

[0019] Further, the top rod is composed of light alloy material.

[0020] Through the above scheme, the overall weight of the ejector rod is significantly reduced through the use of lightweight alloy materials, which not only improves the convenience of operation, but also reduces the additional pressure that may be caused to the screw rod due to excessive weight.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] The press-in screw realizes lightweight design in structure design, while maintaining sufficient strength and connection performance. The hexagonal rod head is convenient for operation with tools, and the flange surface provides a larger contact area to disperse pressure and prevent material deformation during tightening. The design of the conical head enables the screw to more effectively disperse stress during the press-in process, improving the reliability of the connection. In addition, the cooperation of the helical line of the screw rod and the ejector rod ensures the accuracy and stability of the screw when being pressed into the material. The press-in screw meets the lightweight requirement while ensuring the convenience of installation and the firmness of the connection. BRIEF DESCRIPTION OF DRAWINGS
