Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and more specifically to a fastening bolt. Background Technology

[0002] Bolts are common mechanical parts, mainly used to fasten two or more components together to achieve structural fixation and stability. They are cylindrical threaded fasteners that are fitted with nuts. They consist of a head and a threaded rod and require a nut to fasten two parts with through holes. This type of connection is called a bolted connection.

[0003] For example, in a fastening bolt with prior art publication number CN221838719U, the utility model pushes a compression block one through the operating port. The compression block one pushes the lubricating grease to move, and the lubricating grease overcomes the elastic force of the spring to push a compression block two to slide, so that the compression block two does not block the flow port. Until the compression block two can no longer slide, as the space between the compression block one and the compression block two decreases, the lubricating grease will flow out of the body through the flow port, lubricating the bolt and nut, and facilitating disassembly.

[0004] However, the existing technology described above still has the following problems in use: traditional fastening bolts usually have hexagonal holes or cross slots for disassembly and assembly, which limits the process. Furthermore, when using tools for disassembly and assembly, the tools are prone to detaching from the bolt, affecting the disassembly and assembly speed. Therefore, this utility model provides a fastening bolt with high disassembly and assembly stability. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a fastening bolt that allows for installation and disassembly in two ways by setting a hexagonal disassembly port and a cross-shaped disassembly groove on the bolt head, making the operation more flexible. At the same time, a reinforcing block, a compression spring, and a housing are set in the hexagonal disassembly port, and a wear-resistant plate is set in the cross-shaped disassembly groove, which can not only enhance the fastening during the installation and disassembly process, but also prevent slippage and disengagement during disassembly, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fastening bolt, comprising a bolt head and a threaded shank, wherein a hexagonal disassembly opening is provided at the center of the top of the bolt head, a cross-shaped disassembly groove is provided on the bottom wall of the hexagonal disassembly opening, and a plurality of grooves arranged in a circular array are provided on the inner wall of the hexagonal disassembly opening, each groove having a reinforcing component fixedly installed inside, the reinforcing component comprising a housing, a reinforcing block being provided inside the housing, the reinforcing block penetrating the housing and extending into the hexagonal disassembly opening, and a plurality of fixing grooves arranged in a circular array being provided on the inner wall of the cross-shaped disassembly groove, each fixing groove having a wear-resistant plate fixedly installed inside, the wear-resistant plate contacting the screwdriver thereby improving the stability of the screwdriver inserted into the cross-shaped disassembly groove.

[0007] In a preferred embodiment, each wear-resistant pad is machined with anti-slip textures. The anti-slip textures improve the friction of the wear-resistant pad surface, thereby improving the stability between the screwdriver and the Phillips head slot.

[0008] In a preferred embodiment, a compression spring is fixedly provided on one side of each reinforcing block. The end of the compression spring away from the reinforcing block is fixed to the inner wall of the housing. The elastic force of the compression spring pushes the reinforcing block into contact with the hex wrench, thereby improving the stability of the hex wrench.

[0009] In a preferred embodiment, each compression spring is provided with a telescopic rod inside. One end of the telescopic rod is fixed to the reinforcing block, and the other end of the telescopic rod is fixed to the inner wall of the housing. The telescopic rod can limit the movement of the reinforcing block and the compression spring, thereby improving the stability of the reinforcing block and the compression spring.

[0010] In a preferred embodiment, the bolt head has an annular mounting groove at the top, a dust cover is provided in the annular mounting groove, the inner wall of the annular mounting groove is machined with internal threads, the outer wall of the dust cover is machined with external threads, and the dust cover is threadedly connected to the bolt head through the external and internal threads.

[0011] In a preferred embodiment, the top of the dust cover has a groove, and the number of grooves is set to multiple. The multiple grooves are arranged in a circular array on the dust cover. The multiple grooves facilitate the installation personnel to twist the dust cover for installation and disassembly.

[0012] In a preferred embodiment, a rubber sealing ring is fitted on the bottom of the bolt head and the outer wall of the threaded rod, and the number of rubber sealing rings on the threaded rod is set to multiple. The rubber sealing rings are soft in texture, so that the setting of rubber sealing rings can improve the sealing and fastening between the bolt head, the threaded rod and the workpiece.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model provides a hexagonal disassembly port and a cross-shaped disassembly groove on the bolt head, allowing the fastening bolt to be installed and disassembled in two ways, making the operation more flexible. At the same time, a reinforcing block, a compression spring and a housing are set in the hexagonal disassembly port, and a wear-resistant plate is set in the cross-shaped disassembly groove, which can not only enhance the fastening during the installation and disassembly process, but also prevent slippage and disengagement during disassembly.

[0015] 2. By installing a dust cover on the top of the bolt head, the dust cover can form a sealed protection for the hexagonal disassembly port and the cross-shaped disassembly groove, preventing dust and impurities from accumulating and clogging, thereby ensuring the smoothness of subsequent disassembly and assembly operations.

[0023] 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.

[0024] Refer to the instruction manual appendix Figures 1-5This utility model provides a fastening bolt, including a bolt head 1 and a threaded rod 2. A hexagonal disassembly port 3 is provided at the center of the top of the bolt head 1. A cross-shaped disassembly groove 4 is provided on the bottom wall of the hexagonal disassembly port 3. A plurality of grooves 5 are provided on the inner wall of the hexagonal disassembly port 3 in a ring array.

[0025] Each groove 5 is fixedly provided with a reinforcement component 6. The reinforcement component 6 includes a housing 61. The housing 61 is provided with a reinforcement block 62. The reinforcement block 62 passes through the housing 61 and extends into the hexagonal disassembly port 3. A compression spring 66 is fixedly provided on one side of each reinforcement block 62. The end of the compression spring 66 away from the reinforcement block 62 is fixed to the inner wall of the housing 61.

[0026] like Figure 4 and Figure 5 As shown, the inner wall of the cross-shaped disassembly groove 4 is provided with a plurality of fixing grooves 63 arranged in a ring array. Each fixing groove 63 is fixed with a wear-resistant plate 64. Each wear-resistant plate 64 is processed with anti-slip texture 65 on its surface. The anti-slip texture 65 can increase the friction of the wear-resistant plate 64 surface.

[0027] The bolt head 1 has an annular mounting groove 8 at its top, and a dust cover 9 is provided inside the annular mounting groove 8. The inner wall of the annular mounting groove 8 is machined with internal threads, and the outer wall of the dust cover 9 is machined with external threads. The dust cover 9 is threadedly connected to the bolt head 1 through the external and internal threads. The dust cover 9 seals the hexagonal disassembly port 3 to prevent dust and impurities from clogging and affecting the subsequent disassembly of the bolt. The threaded connection is used for fixation, which can effectively prevent the dust cover 9 from detaching from the bolt head 1.

[0028] When tightening the bolts, the installer first removes the dust cover 9 from the bolt head 1. Then, using a hex wrench or screwdriver (Phillips head or flathead screwdriver), the installer turns the bolt head 1 to screw the threaded rod 2 into the threaded hole for fixation. When the hex wrench is inserted, it pushes multiple reinforcing blocks 62 into multiple housings 61. At this time, the reinforcing blocks 62 compress the compression springs 66, and the compression springs 66 generate a reaction force to push the reinforcing blocks 62 against the hex wrench. This can improve the stability of the hex wrench to a certain extent and prevent it from coming loose during the tightening of the bolts. When using a screwdriver, when the screwdriver is inserted into the Phillips head slot 4, it contacts multiple wear-resistant plates 64. The anti-slip texture 65 on the surface of the wear-resistant plates 64 can effectively increase the friction between the screwdriver and the Phillips head slot 4, thereby improving the stability of the screwdriver. Finally, after the bolts are installed, the installer screws the dust cover 9 back into the annular mounting slot 8.

[0029] To improve the sealing performance of fastening bolts, such as Figure 2 and Figure 5As shown, rubber sealing rings 11 are fitted on the bottom of the bolt head 1 and the outer wall of the threaded rod 2, and the number of rubber sealing rings 11 on the threaded rod 2 is set to multiple. When the bolt is installed in place, the rubber sealing ring 11 at the bottom of the bolt head 1 contacts the workpiece and plays a sealing role. The multiple rubber sealing rings 11 on the threaded rod 2 contact the threaded hole wall and can play a sealing and reinforcement role.

[0030] like Figure 5 As shown, each compression spring 66 is provided with a telescopic rod 7 inside. One end of the telescopic rod 7 is fixed to the reinforcing block 62, and the other end of the telescopic rod 7 is fixed to the inner wall of the housing 61. When the reinforcing block 62 moves, the telescopic rod 7 can play a limiting role between the reinforcing block 62 and the housing 61. At the same time, it can also play a limiting role inside the compression spring 66 to prevent the compression spring 66 from deviating too much and affecting the normal movement of the reinforcing block 62.

[0031] The dust cover 9 has a groove 10 on its top. The number of grooves 10 is set to multiple, and the multiple grooves 10 are arranged in a ring array on the dust cover 9. The multiple grooves 10 make it easy for installers to twist the dust cover 9 for installation and disassembly.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
