Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, specifically relating to a double-ended bolt fastener. Background Technology

[0002] In the industrial sector, bolts are critical fasteners whose performance directly affects the stability and safety of mechanical equipment. However, traditional bolts often experience wear, loosening, or even breakage when operating under high loads or harsh environments, which severely impacts their service life and reliability. Utility Model Content

[0003] The main purpose of this utility model is to provide a double-ended bolt fastener to improve the stability and reliability of double-ended bolt fasteners and increase the service life of bolts.

[0004] To achieve the above objectives, this utility model provides a double-ended bolt fastener, which includes a screw rod, with baffles symmetrically arranged at both ends of the screw rod. The diameter of the baffles is larger than the diameter of the screw rod, and a bolt head is provided on the outer surface of the baffles. The diameter of the bolt head is smaller than the diameter of the screw rod.

[0005] This utility model provides a double-ended stud fastener, in which the stud, as the main component, passes through the connector to achieve fastening. Symmetrical baffles are arranged at both ends of the stud; this design provides fixation and support at both ends of the bolt. The diameter of the baffles is larger than the diameter of the stud, ensuring the stability of the connection. This improves the stability and reliability of the double-ended stud fastener and extends the service life of the bolt.

[0006] In one possible implementation, the bolt head structures at both ends of the screw are symmetrical.

[0007] In one possible implementation, the screw has reinforcing ends at both ends, the diameter of which is larger than the diameter of the screw and smaller than the diameter of the baffle. The reinforcing ends provide additional strength and stability, while maintaining the overall structural integrity due to their smaller diameter compared to the baffle.

[0008] In one possible implementation, the baffle is disposed on the reinforced end. This arrangement helps to improve the overall strength and durability of the bolt fastener.

[0009] In one possible implementation, a bowl-shaped protective shell is provided on the reinforced end, and the bowl-shaped protective shell is connected to the inner bottom surface of the baffle. This design can provide additional protection against damage or corrosion to the bolt head, extending the service life of the bolt. Attached Figure Description

[0011] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0012] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0013] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0014] See attached diagram. Figure 1 , Figure 1 This is a schematic diagram of a double-headed bolt fastener structure provided by this utility model, as shown below. Figure 1 As shown, the present invention provides a double-headed bolt fastener including a screw 1, with baffles 2 symmetrically arranged at both ends of the screw 1. The diameter of the baffles 2 is larger than the diameter of the screw 1. A bolt head 3 is provided on the outer surface of the baffles 2, and the diameter of the bolt head 3 is smaller than the diameter of the screw 1.

[0015] This utility model provides a double-ended bolt fastener, in which the bolt 1, as the main component, passes through the connector to achieve fastening. Symmetrical baffles 2 are arranged at both ends of the bolt 1. This design provides fixation and support at both ends of the bolt. The diameter of the baffles 2 is larger than the diameter of the bolt 1, ensuring the stability of the connection. This improves the stability and reliability of the double-ended bolt fastener and extends the service life of the bolt.

[0016] In one possible implementation, the bolt heads 3 at both ends of the screw 1 are symmetrically structured.

[0017] In one possible implementation, the screw 1 has reinforcing ends 4 at both ends. The diameter of the reinforcing ends 4 is larger than the diameter of the screw 1, and smaller than the diameter of the baffle 2. The reinforcing ends 4 provide additional strength and stability, while maintaining the overall structural integrity due to their smaller diameter than the baffle 2.

[0018] In one possible implementation, the baffle 2 is disposed on the reinforced end 4. This arrangement helps to improve the overall strength and durability of the bolt fastener.

[0019] In one possible implementation, a bowl-shaped protective shell 5 is provided on the reinforced end 4, and the bowl-shaped protective shell 5 is connected to the inner bottom surface of the baffle 2. This design can provide additional protection to prevent damage or corrosion to the bolt head 3 and extend the service life of the bolt.

[0020] It is worth mentioning that those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
