[0013] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments. However, the specific implementation methods and embodiments described below are only for illustrative purposes and are not intended to limit the present invention.

[0014] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate directions or positional relationships based on the attached text. Figure 1 The directions or positional relationships shown are only for the convenience of describing the present invention, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0015] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0016] In order to solve the above technical problems, Figure 1-2As shown, the present invention designs a hexagonal flange bolt, comprising a hexagonal bolt head 1, a flange 2 disposed below the hexagonal bolt head 1, and a bolt shank 3 disposed below the flange 2. The hexagonal flange bolt has a greater "support area to stress area ratio" than ordinary bolts, thus being able to withstand higher preload forces and having better anti-loosening properties. This makes the bolt well-suited for connections subjected to high tension or operating in high-temperature and high-pressure environments. The bolt shank 3 is externally threaded, and a polished rod 4 is disposed below the bolt shank 3. The bolt shank 3 is configured to engage with the internal thread of a hexagonal nut 5. The hexagonal nut 5 also includes a straight cylindrical portion 6 disposed below. The polished rod 4 has a mounting hole 7 disposed radially, and a limit post 8 is disposed within the mounting hole 7. The limit post 8 is movable along the axial direction of the mounting hole 7. The straight cylindrical portion 6 is provided with a limit hole 9 adapted to mate with the limit post 8. The limit post 8 is configured to lock the hexagonal nut 5 after being inserted into the limit hole 9. During installation, first pass the bolt rod 3 through the through hole of the part, and then screw on the hexagonal nut 5 on the other side for matching. Since the special matching nut is installed in place, the limiting hole 9 of the straight barrel part 6 can exactly correspond to the limiting column 8. At this time, the limiting column 8 extends from the installation hole 7 and matches the limiting hole 9 on the straight barrel part 6 of the hexagonal nut 5, realizing a new type of locking mechanism. This design can effectively prevent the bolt from loosening or falling off during long-term operation or under vibration or impact, thereby improving the stability and reliability of the connection.

[0017] Further preferred in this embodiment is a hexagonal flange bolt, comprising a hexagonal bolt head 1, a flange plate 2 being provided below the hexagonal bolt head 1, a bolt rod 3 being provided below the flange plate 2, the bolt rod 3 being provided with an external thread, a smooth rod body 4 being provided below the bolt rod 3, the bolt rod 3 being used to cooperate with the inner hole thread of a hexagonal nut 5, the hexagonal nut 5 also including a straight cylindrical portion 6 arranged below, the smooth rod body 4 being provided with a mounting hole 7, the mounting hole 7 being arranged radially, a limiting column 8 being provided in the mounting hole 7, the limiting column 8 being movable along the axial direction of the mounting hole 7, the straight cylindrical portion 6 being provided with a limiting hole 9 adapted to the limiting column 8, and the limiting column 8 being used to complete the locking of the hexagonal nut 5 after being inserted into the limiting hole 9.

[0018] It is further preferred in this embodiment that the limit column 8 is arranged in the mounting hole 7 by a push-type elastic self-locking mechanism, and the push-type elastic self-locking mechanism is used to enable the limit column 8 to switch between the extended and retracted states. The push-type elastic self-locking mechanism enables the limit column 8 to be extended and retracted by a simple pressing action, which is easy and quick to operate and improves the use efficiency. The limit column 8 can firmly lock the hexagonal nut 5 when it is in the extended state to prevent the nut from loosening due to vibration or external force, thereby enhancing the security of the connection. The mechanism can keep the limit column 8 in a specific position after being pressed until it is pressed again. Such a design provides a reliable locking mechanism to ensure the stability of the connection. The push-type elastic self-locking mechanism can work in a variety of environments, including high vibration or impact situations, and environments with large temperature changes, because it does not rely on friction to maintain the locked state.

[0019] It is worth mentioning that the push-type elastic self-locking mechanism is characterized by automatic locking when pressed once and automatic opening when pressed again. It can remain in a specific position after pressing and quickly return to its initial state when pressed again. This mechanism is used in many products, such as ballpoint pens, mobile phone memory card holders, door buckle switches, door cabinet rebounders, emergency stop switches, etc. These structures usually include components such as housings, buckles, pull rods, springs, etc., which are conventional technologies well known to those skilled in the art. The specific structure and working principle are not further described in this utility model.

[0020] It is further preferred in this embodiment that the hexagonal bolt head 1, flange 2 and bolt rod 3 are integrally formed. The hexagonal bolt head 1, flange 2 and bolt rod 3 are integrally formed. This design improves the overall strength and durability of the bolt, and also makes the production process more efficient and reduces assembly costs.

[0021] It is further preferred in this embodiment that the bolt rod 3 is made of alloy steel, which has good mechanical properties, including high strength and wear resistance, and is suitable for use in harsh environments, such as high temperature or heavy load situations.

[0022] It is further preferred in this embodiment that the hexagonal nut 5 and the straight barrel portion 6 are fixedly connected by welding. Welding is a very strong connection method. The hexagonal nut 5 and the straight barrel portion 6 after welding form a whole, which can withstand a greater preload and working load, and is therefore suitable for occasions with heavy loads or high pressures.

[0023] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
