Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically a hexagonal head bolt with a splitting function. Background Technology

[0002] Hex head bolts are fasteners widely used in industry, construction, machinery and other fields. Their core function is to fix and assemble components through threaded connections. The head of a hex bolt is a hexagonal protrusion. Torque is applied by wrench or socket tool. They are suitable for scenarios that require high preload, such as steel structure engineering, bridges, and automobile chassis fixing.

[0003] However, existing hexagonal head bolts are not convenient for quick and stable disassembly, which means that when the bolt head or shank is damaged, the whole bolt needs to be replaced, reducing the service life of the bolt. Therefore, there is an urgent need for a hexagonal head bolt with a disassembly function to solve the above problems. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment of this utility model provides: a hexagonal head bolt with a splitting function, including a bolt housing 4 for support, and an external thread 5 located on the outside of the bolt housing 4.

[0022] Positioning device 2 is threadedly connected to the upper end face of bolt housing 4. A rust-proof coating 1 is provided on the outside of the upper end face of positioning device 2. Positioning device 2 is used for docking and limiting.

[0023] The threaded guide groove 3 is located at the center of the upper end face of the bolt housing 4, and six sets of positioning guide plates 6 are equidistantly provided on the upper end face of the bolt housing 4.

[0024] The positioning device 2 includes an external hexagonal rotating plate 21, a limiting internal hexagonal rotating plate 22 is rotatably engaged at the middle of the inner end face of the external hexagonal rotating plate 21, and a threaded guide shaft 23 is provided at the center of the lower end face of the limiting internal hexagonal rotating plate 22. A positioning pad 25 is provided near the outside of the lower end face of the external hexagonal rotating plate 21, and six sets of positioning clamping plates 24 are equidistantly arranged inside the lower end face of the positioning pad 25. Six sets of anti-slip pads 26 are equidistantly arranged near the outside of the lower end face of the positioning pad 25.

[0025] The anti-rust coating 1 is fixedly installed on the outer end face of the external hexagonal plate 21. The anti-rust coating 1 is an anti-rust and wear-resistant coating that can effectively improve the anti-rust performance of the external hexagonal plate 21.

[0026] The threaded guide shaft 23 is threadedly connected to the bolt housing 4 through the threaded guide groove 3, which facilitates a quick and easy disassembly operation between the external hexagonal rotating plate 21 and the bolt housing 4.

[0027] The positioning pad 25 is adapted to the positioning guide plate 6 through the positioning clip 24 and then slidably clipped onto the upper end face of the bolt housing 4. The sliding adaptation of the six sets of positioning clips 24 and positioning guide plates 6 can improve the accuracy of the alignment connection between the external hexagonal plate 21 and the bolt housing 4, and also improve the torsional force limiting the external hexagonal plate 21 and the bolt housing 4.

[0028] The bottom of the anti-slip pad 26 is provided with anti-slip protrusions at equal intervals, which can improve the friction at the subsequent bolt tightening point, thereby improving the stability of the bolt and the external workpiece locking limit.

[0029] Working principle: When using this device, if it is necessary to disassemble the bolt housing 4 and the external hexagonal plate 21, the operator can insert an external tool into the limiting internal hexagonal plate 22 and then rotate the limiting internal hexagonal plate 22. This allows the limiting internal hexagonal plate 22 to be threadedly connected to the threaded guide groove 3, thereby separating it from the bolt housing 4. This facilitates the subsequent disassembly of the external hexagonal plate 21 from the bolt housing 4. The anti-rust coating 1 on the outside of the limiting internal hexagonal plate 22 effectively improves its anti-rust and wear resistance, and the anti-slip pad 26 improves the support stability of the positioning pad 25 on the outside of the workpiece.

[0030] 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.
