Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a hand-tightening locking and anti-loosening bolt. Background Art

[0002] In certain application scenarios, the display modules assembled into LED displays require quick disassembly and installation for maintenance and replacement. Currently, the industry generally uses elastic rotating locks to achieve this. However, due to the limited elastic force, elastic locks can easily release and have low reliability in certain strong environments, making them unable to guarantee reliable locking. Utility Model Content

[0003] The main purpose of the utility model is to provide a hand-tightening locking anti-loosening bolt, which aims to ensure that the bolt is locked reliably and does not fall off after being loosened.

[0004] To achieve the above-mentioned purpose, the utility model proposes a hand-tightened locking anti-slip bolt, comprising a bolt body for fixing a connection module, wherein the bolt body is sequentially provided with a bolt tooth portion, an anti-slip structure, and a handle portion, and an anti-slip annular groove is provided at one end of the anti-slip structure close to the bolt tooth portion, and the bolt tooth portion, anti-slip structure, handle portion, and anti-slip annular groove are coaxially arranged, and an anti-slip soft rubber ring with an outer diameter larger than that of the anti-slip structure is provided in the anti-slip annular groove.

[0005] In one embodiment of the present application, the anti-slip structure includes a connecting portion facing the handle portion for connecting to the handle portion, and the orthographic projection of the connecting portion is a polygon.

[0006] In one embodiment of the present application, a connecting groove is coaxially formed on the connecting portion, and the handle portion is covered on the connecting portion and is snapped into the connecting groove.

[0007] In one embodiment of the present application, a hexagonal groove is formed on the end surface of the connecting portion facing the handle portion, and a hexagonal recessed hole is formed at one end of the handle portion corresponding to the hexagonal groove for an external tool to disassemble and assemble the bolt body.

[0008] In one embodiment of the present application, the handle portion is symmetrically provided with at least two anti-slip portions along the central axis.

[0009] In one embodiment of the present application, the anti-slip portion is provided with a plurality of anti-slip grooves arranged in an array perpendicular to the rotation direction of the bolt body.

[0010] In one embodiment of the present application, a double-eared operating portion is provided at the top end of the handle portion, and a side wall of the operating portion is connected to the anti-slip portion and is provided with an anti-slip groove.

[0011] By adopting the above technical solution, the utility model has the following advantages:

[0012] 1. A through hole is provided on the display box for fixing the LED display module, which corresponds to the bolt body. An anti-slip cover groove is provided on the end face of the through hole facing the handle. An anti-slip hole with a diameter larger than the outer diameter of the bolt body and smaller than the outer diameter of the anti-slip soft rubber ring is coaxially provided in the anti-slip cover groove and corresponding to the through hole. During operation, the anti-slip structure passes through the anti-slip hole, and the anti-slip rubber ring abuts against the anti-slip hole. The anti-slip rubber ring is pushed into the anti-slip cover groove, and the handle is turned to connect the bolt thread to the locking nut on the display module. This can stably lock the display module and the display box together. The anti-slip soft rubber ring is used to prevent the bolt body from falling out of the display box, which can effectively improve the locking reliability.

[0013] 2. The bolt teeth, anti-slip structure, handle, and anti-slip annular groove are coaxially arranged, so that the twisting force of the handle can be stably transmitted to the bolt teeth, making the disassembly and assembly of the bolt body more stable and effective in improving the disassembly and assembly efficiency. In addition, the anti-slip soft rubber ring is installed in the anti-slip annular groove, so that the force of the anti-slip soft rubber ring falling off the anti-slip annular groove can be greater than the force of the bolt body being pushed into the anti-slip hole. The resistance between the anti-slip soft rubber ring and the anti-slip hole can prevent the anti-slip soft rubber ring from falling out of the anti-slip annular groove, making the bolt body more convenient to use and conducive to improving the disassembly and assembly efficiency.

[0021] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] Reference Figures 1 to 3 To achieve the above-mentioned purpose, the utility model proposes a hand-tightening locking anti-slip bolt, comprising a bolt body 1 for fixing a connection module, wherein the bolt body 1 is provided with a bolt tooth portion 11, an anti-slip structure 12, and a handle portion 3 in sequence, and an anti-slip annular groove 13 is provided at one end of the anti-slip structure 12 close to the bolt tooth portion 11. The bolt tooth portion 11, the anti-slip structure 12, the handle portion 3, and the anti-slip annular groove 13 are coaxially arranged, and an anti-slip soft rubber ring 14 with an outer diameter larger than that of the anti-slip structure 12 is provided in the anti-slip annular groove 13.

[0023] A through hole is provided on the display box body corresponding to the bolt body 1 for fixing the LED display module, and an anti-slip cover groove is provided on the end face of the through hole facing the handle part 3, and an anti-slip hole with a diameter larger than the outer diameter of the bolt body 1 and smaller than the outer diameter of the anti-slip soft rubber ring 14 is coaxially provided in the anti-slip cover groove corresponding to the through hole. During operation, the anti-slip structure 12 passes through the anti-slip hole, and the anti-slip rubber ring abuts against the anti-slip hole. The anti-slip rubber ring is pushed into the anti-slip cover groove by pushing, and the handle part 3 is turned to connect the bolt tooth part 11 to the locking nut on the display module, so that the display module and the display box body can be stably locked together. The anti-slip soft rubber ring 14 is used to prevent the bolt body 1 from falling out of the display box body, which can effectively improve the locking reliability.

[0024] The bolt teeth 11, anti-slip structure 12, handle part 3, and anti-slip annular groove 13 are coaxially arranged, so that the twisting force of the handle part 3 can be stably transmitted to the bolt teeth 11, making the disassembly and assembly of the bolt body 1 more stable and effective in improving the disassembly and assembly efficiency. In addition, the anti-slip soft rubber ring 14 is installed by using the anti-slip annular groove 13, so that the force of the anti-slip soft rubber ring 14 falling off the anti-slip annular groove 13 can be greater than the force of pushing the bolt body 1 into the anti-slip hole. The resistance between the anti-slip soft rubber ring 14 and the anti-slip hole can prevent the anti-slip soft rubber ring 14 from falling off the anti-slip annular groove 13, making the bolt body 1 more practical and convenient, which is conducive to improving the disassembly and assembly efficiency.

[0025] See also Figures 2 to 3 The anti-slip structure 12 includes a connecting portion 2 for connecting to the handle portion 3 facing the handle portion 3, and the positive projection of the connecting portion 2 is a polygon.

[0026] The polygonal projection of the connecting portion 2 can ensure that when the handle portion 3 is injection-molded, the handle portion 3 made of plastic material has higher strength when wrapping around the connecting portion 2. At the same time, it can ensure the structural integrity when the handle portion 3 is rotated, and prevent the handle portion 3 from being peeled off from the connecting portion 2 and damaged.

[0027] See also Figures 2 to 3 A connecting groove 21 is coaxially opened on the connecting portion 2 , and the handle portion 3 is covered on the connecting portion 2 and snapped into the connecting groove 21 .

[0028] The connecting groove 21 can further strengthen the structural strength of the connection between the handle portion 3 and the connecting portion 2 , while preventing the handle portion 3 from being peeled off from the connecting portion 2 when the bolt body 1 is removed from the display box.

[0029] See also Figures 1 to 3 A hexagonal groove 22 is formed on the end surface of the connecting portion 2 facing the handle portion 3 , and a hexagonal recessed hole 31 is formed at one end of the handle portion 3 corresponding to the hexagonal groove 22 for disassembling the bolt body 1 with an external tool.

[0030] The connecting part 2 is made of metal. In order to prevent the plastic handle part 3 from being damaged during use and causing the bolt to stop working, a hexagonal groove 22 is provided on the end face of the connecting part 2 away from the bolt thread part 11. In this way, even if the handle part 3 is damaged, the bolt body 1 can be disassembled and installed by external tools such as hexagonal wrenches and hexagonal screwdrivers, making it more convenient to use and improving disassembly and assembly efficiency.

[0031] See also Figures 1 to 2 The handle portion 3 is symmetrically provided with at least two anti-slip portions 32 along the central axis.

[0032] The handle portion 3 itself is cylindrical and can be easily installed. In order to make the handle portion 3 easy to use, an anti-slip portion 32 is cut out at a symmetrical position of the handle portion 3. In order to further improve the anti-slip effect, an anti-slip ridge or other anti-slip structure can be provided on the anti-slip portion 32 along the direction of rotation perpendicular to the bolt body 1 to further increase local friction, making the bolt more convenient to use.

[0033] See also Figures 1 to 2 The anti-slip portion 32 has a plurality of anti-slip grooves 33 arranged in an array perpendicular to the rotation direction of the bolt body 1 .

[0034] In order to further improve the anti-slip effect, an anti-slip groove 33 can be provided on the anti-slip portion 32 along the rotation direction perpendicular to the bolt body 1 , thereby increasing local friction and making the bolt more convenient to use.

[0035] See also Figures 1 to 3 The top of the handle portion 3 is provided with a double-ear shaped operating portion 34 , the side wall of the operating portion 34 is connected to the anti-slip portion 32 and is provided with an anti-slip groove 33 .

[0036] The double-eared operating portion 34 is conducive to the user's exertion of force, and the operating portion 34 is arranged between the opposite anti-slip portions 32, so that the handle portion 3 can be provided with more anti-slip grooves 33, which is conducive to increasing friction and thereby improving the disassembly and assembly efficiency of the bolt body 1.
