Description

Technical Field

[0001] This utility model relates to the field of bolt structure technology, specifically to a flange bolt with a multi-directional self-locking structure. Background Technology

[0002] A flange bolt consists of a hexagonal head, a flange, and a threaded rod. The hexagonal head and flange are a single unit consisting of a gasket under the hexagon and a hexagonal fixing plate. The threaded rod is a cylinder with external threads. The two parts form a single bolt, which is then fitted with a corresponding nut structure.

[0003] Flange nuts are mostly used in pipe connections or on workpieces that require increased nut contact surface. During long-term use, flange nuts are prone to loosening. Conventional flange nut locking methods often involve increasing the contact surface or using threaded self-locking, but they still loosen over time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a flange bolt with a multi-directional self-locking structure, addressing the shortcomings mentioned in the background art.

[0005] To solve the above technical problems, the technical solution provided by this utility model is: a flange bolt with a multi-directional self-locking structure, including a bolt structure and a nut structure. The bolt structure includes a hexagonal head and a bottom thread. The nut structure has a first internal thread that matches the thread. The top of the nut structure has an auxiliary washer structure, and the bottom has an auxiliary hexagonal locking block.

[0006] The auxiliary gasket structure has a first auxiliary self-locking groove at the bottom, and the nut structure has a first auxiliary ring block at the top that matches the first auxiliary self-locking groove;

[0007] The nut structure has a second auxiliary self-locking groove at the bottom, the auxiliary hexagonal locking block has a second auxiliary ring block at the top that matches the second auxiliary self-locking groove, the auxiliary hexagonal locking block has a second internal thread at the top that matches the screw, and the auxiliary hexagonal locking block has a groove below the second internal thread.

[0008] Furthermore, an auxiliary disk is provided between the hexagonal head and the screw, and the bottom of the auxiliary disk, located outside the screw, is provided with a first sealing ring and a first friction pad, which facilitates the operation of increasing friction, fastening and sealing.

[0009] Furthermore, the auxiliary gasket structure is provided with a second sealing gasket on top to increase the gasket's friction.

[0010] Furthermore, the top of the first auxiliary self-locking groove and the second auxiliary self-locking groove are respectively provided with a second sealing ring and a third sealing ring, which can increase the sealing performance of the overall structure.

[0011] Furthermore, the diameter of the groove is larger than that of the second internal thread, which facilitates end self-locking operation.

[0012] The advantages of this multi-directional self-locking flange bolt compared with the prior art are as follows: This device uses a bolt structure, a nut structure and an auxiliary hexagonal locking block arranged from top to bottom for initial locking, and then uses a multi-stage self-locking groove and an auxiliary ring block to form a multi-directional locking, which can ensure the stability and locking of the bolt.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3 A multi-directional self-locking flange bolt includes a bolt structure 1 and a nut structure 2. The bolt structure 1 includes a hexagonal head 4 and a bottom thread 5. The nut structure 2 has a first internal thread 15 that mates with the thread 5. The nut structure 2 has an auxiliary washer structure 9 at the top and an auxiliary hexagonal locking block 3 at the bottom. The bolt 5 engages with the nut structure 2 and the auxiliary washer structure 9 for initial locking, and then the auxiliary hexagonal locking block 3 locks the extended portion of the bolt 5 at the end. The bidirectional locking by the nut structure 2 and the auxiliary hexagonal locking block 3 ensures the initial locking of the structure.

[0019] The auxiliary washer structure 9 has a first auxiliary self-locking groove 10 at its bottom, the nut structure 2 has a first auxiliary ring block 12 that matches the first auxiliary self-locking groove 10 at its top, the nut structure 2 has a second auxiliary self-locking groove 13 at its bottom, and the auxiliary hexagonal locking block 3 has a second auxiliary ring block 14 that matches the second auxiliary self-locking groove 13 at its top. By having the first auxiliary self-locking groove 10 engage with the first auxiliary ring block 12, and the second auxiliary self-locking groove 13 engage with the second auxiliary ring block 14, the bolt structure 1, nut structure 2, auxiliary hexagonal locking block 3, and auxiliary washer structure 9 can be locked simultaneously, preventing damage during the locking process. When shaking occurs, the bolt structure 1, nut structure 2, auxiliary hexagonal locking block 3, and auxiliary washer structure 9 will not loosen, ensuring multi-directional locking operation. The auxiliary hexagonal locking block 3 has a second internal thread 16 that matches the screw 5 at its top. The auxiliary hexagonal locking block 3 has a groove 17 located below the second internal thread 16. The diameter of the groove 17 is larger than that of the second internal thread 16. The top of the first auxiliary self-locking groove 10 and the second auxiliary self-locking groove 13 are respectively provided with a second sealing ring 18 and a third sealing ring 19. The second sealing ring 18 and the third sealing ring 19 can maintain the sealing of the locking end.

[0020] An auxiliary disk 6 is provided between the hexagonal head 4 and the screw 5. The bottom of the auxiliary disk 6 is located outside the screw 5 and is provided with a first sealing ring 7 and a first friction pad 8. The top of the auxiliary gasket structure 9 is provided with a second friction pad 11. The provision of the first friction pad 8 and the second friction pad 11 can increase the friction between the contact surfaces of the bolt structure 1 and the auxiliary gasket structure 9 and the locked structure, thus ensuring further locking performance.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
