Description

Technical Field

[0001] This utility model relates to the technical field of bolts, specifically a high-strength bolt structure. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is fitted with a nut. It consists of a head and a threaded shank, and is used to fasten two parts with through holes.

[0003] For example, a high-strength bolt structure with authorization announcement number "CN219062201U" solves the problem that the bolt head is prone to breakage and separation from the shank in existing high-strength bolt structures, thus reducing the practicality of the bolt. The above-mentioned structure strengthens the connection strength between the stud structure and the bolt head structure by setting a reinforcing connecting plate at the connection point. By adding a rubber buffer pad and an external protective collar to the bolt head structure, the impact resistance of the bolt head structure under lateral impact can be improved. However, considering that existing high-strength bolt structures reinforce the bolt head structure by wrapping it with a protective head and strengthening the internal material fixation of the stud, the strength of the stud remains the same and cannot meet the needs of various environments. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing high-strength bolt structures, where the studs have the same strength, cannot meet the needs of various environments, and therefore proposes a high-strength bolt structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength bolt structure, comprising a bolt body and a threaded groove, wherein the inner wall of the bolt body is machined with a threaded groove and a fixing hole is machined on the inner wall of the bolt body, the outer wall of the bolt body abuts against a reinforcing ring, the outer wall of the reinforcing ring is fixedly connected to a connecting cap, and a reinforcing mechanism is connected to the inner wall of the bolt body.

[0006] Preferably, the reinforcing mechanism includes a reinforcing rib, the outer wall of which is movably connected to the bolt body, the end of which is movably connected to the connector, the inner wall of which abuts against the fixing rod, and the outer wall of which abuts against the reinforcing rib.

[0007] Preferably, the outer wall of the fixing rod abuts against the fixing hole, and the end of the reinforcing rib is fixedly connected to the connecting cap.

[0008] Preferably, the lower end of the connecting cap is fixedly connected to the square block, and the outer wall of the square block abuts against the reinforcing rib.

[0009] Preferably, the inner wall of the connecting cap is machined with a hexagonal groove, and the outer wall of the connecting cap abuts against the connecting strip.

[0010] Preferably, the outer wall of the connecting strip is fixedly connected to the protective sleeve.

[0011] The high-strength bolt structure proposed in this utility model has the following advantages: the connector is inserted into the interior of the threaded body, and the inner wall of the connector also enters the reinforcing rib. The fixing rod is inserted into the fixing hole and connector on the threaded body, so that the connector wraps and protects the connector cap, and the whole assembly is completed. By inserting a reinforcing rib with higher hardness into the interior of the bolt body, the reinforcing rib on the connector cap can be replaced to meet the needs of various environments.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1: Please refer to Figure 1-6 In this embodiment, a high-strength bolt structure includes a bolt body 1 and a threaded groove 2. The inner wall of the bolt body 1 is machined with a threaded groove 2 and a fixing hole 3. The outer wall of the bolt body 1 abuts against a reinforcing ring 4. The outer wall of the reinforcing ring 4 is fixedly connected to a connecting cap 5. A reinforcing mechanism 6 is connected to the inner wall of the bolt body 1.

[0021] The reinforcement mechanism 6 includes a reinforcing rib 601. By inserting a higher-hardness reinforcing rib 601 inside the bolt body 1, the strength of the bolt body 1 is improved. The outer wall of the reinforcing rib 601 is movably connected to the bolt body 1, and the end of the reinforcing rib 601 is movably connected to the connector 602. The reinforcing rib 601 is made of tungsten steel, stainless steel, or Swedish powder steel, which has very high hardness and can be selected according to different environments. The inner wall of the connector 602 abuts against the fixing rod 603, and the outer wall of the fixing rod 603 abuts against the reinforcing rib 601.

[0022] The connector 602 is inserted into the interior of the threaded body 1, and the inner wall of the connector 602 also enters the reinforcing rib 601. The fixing rod 603 is inserted into the fixing hole 3 on the threaded body 1 and the connector 602, so that the connector 602 wraps and protects the connecting cap 5, and the whole is assembled. After the reinforcing rib 601 with higher hardness is inserted into the interior of the bolt body 1, the reinforcing rib 601 on the connecting cap 5 can be replaced to meet the needs of various environments.

[0023] The outer wall of the fixing rod 603 abuts against the fixing hole 3, the end of the reinforcing rib 601 is fixedly connected to the connecting cap 5, the lower end of the connecting cap 5 is fixedly connected to the square block 7, the outer wall of the square block 7 abuts against the reinforcing rib 601, the inner wall of the connecting cap 5 is machined with a hexagonal groove 8, the outer wall of the connecting cap 5 abuts against the connecting strip 9, and the outer wall of the connecting strip 9 is fixedly connected to the protective sleeve 10.

[0024] Working principle:

[0025] By inserting the reinforcing rib 601 on the connecting cap 5 into the bolt body 1, the inner wall of the reinforcing ring 4 on the connecting cap 5 will press against the bolt body 1. The square block 7 on the connecting cap 5 is inserted into the bolt body 1, fixing the position between the bolt body 1 and the connecting cap 5. At the same time, the connecting head 602 is inserted into the threaded body 1, and the inner wall of the connecting head 602 will also enter the reinforcing rib 601. The fixing rod 603 is inserted into the fixing hole 3 on the threaded body 1, so that the fixing rod 603 fixes the reinforcing rib 601 and the connecting head 602. The connecting head 602 and the connecting strip 9 are inserted into the connecting cap 5, so that the connecting head 602 wraps and protects the connecting cap 5. The whole assembly is completed. After the overall strength of the bolt body 1 is tested, the reinforcing rib 601 with higher hardness is inserted into the bolt body 1, and the strength of the bolt body 1 is improved under bending and compression.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
