AI Technical Summary
The traditional bolts lack a reinforcement structure between the rotating part and the stud part, which leads to the need to control the input torque during rotation, which easily leads to breakage at the connection.
A reinforcement part in a round shape is connected between the stud part and the rotating part, and a tower spring is installed on the reinforcement part. The small head end of the tower spring is embedded in the slot, and the large head end is against the rotating part. The other end of the tower spring is fixed by the positioning groove to enhance the torsion resistance of the bolt.
It improves the torsional resistance and use strength of the bolts, prevents breakage at the connection during spinning, and achieves greater input torque capability.

Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, and more specifically, it relates to a high-strength bolt. Background Art
[0002] There is no strengthening structure between the rotating part and the stud part of the traditional bolt. Excessive torque will cause the connection to break, so it is necessary to control the input torque during screwing. Accordingly, the present utility model proposes a high-strength bolt. Summary of the Utility Model
[0003] The purpose of the present utility model is to overcome the deficiencies in the above-mentioned prior art and provide a high-strength bolt, which has the characteristics of large input torque and high use strength.
[0004] To solve the above technical problems, the purpose of the present utility model is achieved as follows: A high-strength bolt according to the present utility model includes a rotating part and a stud part. A frustum-shaped strengthening part is connected in series between the stud part and the rotating part. The large circular surface end of the strengthening part is connected to the rotating part, and the small circular surface end is connected to the stud part. A closed-ring-shaped card slot is formed on the side surface of the strengthening part. A conical spring is sleeved on the strengthening part. The small head end of the conical spring is embedded in the card slot, and the large head end abuts against the rotating part.
[0005] The present utility model is further arranged as: A positioning slot which is also in a closed-ring shape and for the large head end of the conical spring to be embedded is formed on the rotating part.
[0006] The present utility model is further arranged as: The card slot is arranged close to the stud part.
[0007] In summary, the present utility model has the following beneficial effects:
[0008] 1. By connecting a frustum-shaped strengthening part in series between the stud part and the rotating part, the torsional resistance performance of the bolt is enhanced, and the use strength is improved.
[0009] 2. By sleeving a conical spring on the frustum-shaped strengthening part, one end of the conical spring is connected to the strengthening part, and the other end abuts tightly against the rotating part, which is used to offset the torque between the stud part and the rotating part appropriately, so as to further enhance the torsional resistance performance of the bolt. Brief Description of the Drawings
[0010] Figure 1 is the overall structural schematic diagram of the present utility model;
[0011] Figure 2 is the partial structural schematic diagram of the present utility model. Detailed Description of the Invention
[0012] To enable those skilled in the art to better understand the technical solution of the present utility model, the following describes the preferred implementation of the present utility model in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.
[0013] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.
[0014] Embodiment 1
[0015] Refer to Figure 1 and Figure 2 As shown, a high-strength bolt involved in this embodiment includes a rotating part 1 and a stud part 2. A frustum-shaped strengthening part 3 is connected in series between the stud part 2 and the rotating part 1. The large circular surface end of the strengthening part 3 is connected to the rotating part 1, and the small circular surface end is connected to the stud part 2. A closed-ring-shaped clamping groove 4 is formed on the side surface of the strengthening part 3. A conical spring 5 is sleeved on the strengthening part 3. The small head end of the conical spring 5 is embedded in the clamping groove 4, and the large head end abuts against the rotating part 1.
[0016] Further, the clamping groove 4 is arranged close to the stud part 2.
[0017] In this embodiment, when the bolt is subjected to torque, the stud part 2 makes a small circumferential movement relative to the rotating part 1 microscopically. During the twisting of the bolt, since the small head end of the conical spring 5 is embedded in the clamping groove 4, this end follows the movement until the conical spring 5 is moderately twisted. When the conical spring 5 deforms due to the twisting, a reaction force will be generated, and this reaction force can offset the torque acting on the bolt appropriately to prevent the bolt connection from breaking during screwing.
[0018] Embodiment 2
[0019] Refer to Figure 1 and Figure 2 As shown, a high-strength bolt involved in this embodiment is further provided, based on Embodiment 1, with a positioning groove 6 which is also in a closed-ring shape and for the large head end of the conical spring 5 to be embedded, formed on the rotating part 1.
[0020] In this embodiment, through the formation of the positioning groove 6, it is used for positioning the tail end of the conical spring 5.
[0021] The high-strength bolt involved in the present utility model enhances the torsional resistance performance of the bolt and improves the service strength by connecting a frustum-shaped reinforcing part in series between the stud part and the rotating part; and further enhances the torsional resistance performance of the bolt by sleeving a conical spring on the frustum-shaped reinforcing part, with one end of the conical spring connected to the reinforcing part and the other end abutted against the rotating part to offset the torque between the stud part and the rotating part appropriately. The overall function is perfect and the practicability is strong.
