[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] As Figures 1 to 5 shown, the present invention provides an anti-loosening bolt, including a head 1. A connecting column 2 is fixedly installed below the head 1. A screw 3 is fixedly installed at the bottom of the connecting column 2. A blue Loctite anti-loosening glue 4 is provided inside the screw 3. A connecting hole 5 and a spare disassembly port 6 are opened inside the head 1. An anti-blocking strip 7 is provided inside the spare disassembly port 6. A weight-reducing groove 8 is opened at the bottom of the head 1. A silicone pad 9 is fixedly installed inside the weight-reducing groove 8.
[0021] The diameter value of the connecting column 2 is greater than the diameter value of the screw 3. The main function is to achieve a connecting effect and increase the firmness of the connection between the head 1 and the screw 3. After installation, it can prevent the screw 3 from breaking after long-term connection.
[0022] Among them, there are multiple blue Loctite anti-loosening glues 4. The multiple blue Loctite anti-loosening glues 4 are evenly distributed inside the screw 3. The multiple blue Loctite anti-loosening glues 4 are respectively located at the second thread to the seventh thread counted from the bottom of the screw 3, and are all located between 90° and 180° of the screw 3.
[0023] The main function of the multiple blue Loctite anti-loosening glues 4 is to be applied inside the external thread of the screw 3, mainly to increase the firmness of the installation of the screw 3 and prevent loosening between the screw 3 and the fixing part.
[0024] Among them, the connecting hole 5 is in the shape of a six-pointed star, and the center point of the connecting hole 5 coincides with the center point of the head 1.
[0025] The main function of the connecting hole 5 is to facilitate the insertion of a tool into the head 1, so as to drive the connecting hole 5 and the screw 3 to rotate, achieving the effect of convenient installation.
[0026] Among them, there are two spare disassembly ports 6. The two spare disassembly ports 6 are respectively located on the front and back sides of the connecting hole 5. There are two anti-blocking strips 7. The two anti-blocking strips 7 are both located inside the two spare disassembly ports 6.
[0027] The main function of the two spare disassembly ports 6 is that when the inside of the connection hole 5 is damaged by the force of being twisted, it will become difficult to twist in the reverse direction to disassemble the spare disassembly port 6. At this time, when a tool is inserted into the inside of the spare disassembly port 6, the tool can drive the head 1 and the screw 3 to be disassembled by the principle of leverage, so as to achieve the effect of facilitating disassembly.
[0028] Among them, the weight reduction groove 8 is located on the outer side of the connection column 2. The inside of the weight reduction groove 8 is hollow, and the weight reduction groove 8 is annular.
[0029] The main function of the silica gel pad 9 is to reduce the weight inside the head 1, so as to reduce the overall weight of the component. At the same time, it can reduce the cost of certain production materials.
[0030] Among them, there are multiple silica gel pads 9. The multiple silica gel pads 9 are all located on the outer side of the connection column 2. The silica gel pads 9 are spherical, and the material of the silica gel pads 9 has a certain elasticity.
[0031] The main function of the silica gel pad 9 is that after the screw 3 is engaged with the fixing part, the bottom of the silica gel pad 9 is engaged with the surface of the fixing part. At the same time, due to the certain elasticity of the silica gel pad 9, the friction between the silica gel pad 9 and the fixing part can be increased, so as to prevent loosening between the screw 3 and the fixing part.
[0032] The working principle and usage process of the present utility model:
[0033] First, insert a tool into the inside of the connection hole 5 to drive the connection hole 5 to rotate. At the same time, dock the screw 3 with the nut inside the fixing part, and after screwing, engage and install the screw 3 with the fixing part;
[0034] At this time, since there are multiple blue Loctite anti-loosening adhesives 4 inside the screw 3, the multiple blue Loctite anti-loosening adhesives 4 are respectively located at the second thread to the seventh thread counted from the bottom of the screw 3, and are all between 90° and 180° of the screw 3. After the screw 3 is installed with the fixing part, since the multiple blue Loctite anti-loosening adhesives 4 are applied inside the outer thread of the screw 3, the firmness of the screw 3 installation is increased, and loosening between the screw 3 and the fixing part is prevented;
[0035] At the same time, since the silica gel pad 9 is fixedly installed at the bottom of the head 1 and the silica gel pad 9 has a certain elasticity, after the screw 3 is engaged with the fixing part, the bottom of the silica gel pad 9 is engaged with the surface of the fixing part. At the same time, due to the certain elasticity of the silica gel pad 9, the friction between the silica gel pad 9 and the fixing part can be increased, strengthening the effect of the screw 3;
[0036] Finally, a weight-reducing groove 8 is provided at the bottom of the head 1. The weight-reducing groove 8 is circular and hollow inside. Its main function is to reduce the weight of the head 1, achieving the effect of saving materials. At the same time, since a spare disassembly opening 6 is provided inside the head 1, when the screw 3 needs to be disassembled and repaired after being engaged with the fixing part for a long time, as the inside of the connecting hole 5 may be worn, at this time, inserting a tool into the inside of the spare disassembly opening 6 can drive the head 1 to drive the head 1 and the screw 3 to be disassembled through the principle of leverage, thus achieving the effect of facilitating disassembly.
