[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 3 As shown, the utility model provides an anti-slip bolt structure, including a bolt body 1, a nut 2 is threadedly connected to the surface of the bolt body 1, an anti-slip assembly 3 is connected to the bottom of the bolt body 1, and the anti-slip assembly 3 includes a notch 301 and a spring 302, two groups of notches 301 are respectively opened on both sides of the bottom of the bolt body 1, a spring 302 is arranged inside the notch 301, a push block 303 is connected to one side of the spring 302, and a fixing block 303 is connected to one side of the push block 303. 04, a shift block 305 is connected to the bottom of the push block 303, and the push block 303 forms an elastic structure through the slot 301 and the spring 302. An oblique opening is provided on the outer surface of one side of the fixed block 304, and a fixed connection is formed between the push block 303 and the shift block 305. The push block 303 is in a rectangular shape, and the outer surface of the push block 303 fits the inner surface wall of the slot 301. The shift block 305 is in a rectangular shape, and the size of the spring 302 is smaller than that of the slot 301.

[0024] The effect achieved by the entire embodiment 1 is that after the bolt body 1 penetrates the plate to be fixed, the nut 2 can be pushed from the bottom of the bolt body 1 to the surface of the bolt body 1. When the nut 2 contacts the fixing block 304, the nut 2 can be pushed continuously so that the top surface of the nut 2 can squeeze the bevel surface of the fixing block 304. When the bevel surface of the fixing block 304 is squeezed, the fixing block 304 will also drive the spring 302 to be squeezed through the push block 303, so that the spring 302 is in a contracted state. At the same time, the fixing block 304 itself will also shrink into the notch 301. When the nut 2 is completely installed in the bolt After the surface of the bolt body 1 is plugged in, the fixing block 304 is no longer squeezed, and the spring 302 will push the push block 303 through its own elasticity, so that the fixing block 304 can pop out, thereby limiting the nut 2 and preventing the nut 2 from falling off. When the nut 2 is removed, the two sets of shift blocks 305 can be pushed inward at the same time, so that the shift block 305 can push the push block 303 to drive the fixing block 304 to shrink into the notch 301. When the fixing block 304 is completely retracted into the notch 301, the nut 2 can be removed at this time. This avoids the problem that the existing nut 2 is difficult to disassemble after installation.

[0025] Embodiment 2, as Figure 1 , Figure 2 and Figure 4 As shown, a reinforcement component 4 is provided at the top of the bolt body 1, and the reinforcement component 4 includes a through hole 401 and a flow hole 402. The through hole 401 is opened at the top of the bolt body 1, and two groups of the flow holes 402 are opened on the outer surfaces of both sides of the bolt body 1 and are connected to the through hole 401.

[0026] The effect achieved by the entire embodiment 2 is that after the bolt body 1 is installed, when there is no need to consider disassembling the bolt body 1 later, the liquid glue can be pushed into the bolt body 1 through the through hole 401, and the liquid glue can flow out from the flow hole 402. In this way, the subsequent connection between the bolt body 1 and the plate can be made more secure, thereby improving the practicality of the bolt body 1, and whether to inject liquid glue can be considered according to actual conditions.

[0027] Working principle: after the bolt body 1 passes through the plate to be fixed, the nut 2 can be pushed from the bottom of the bolt body 1 to the surface of the bolt body 1 and threadedly connected to the bolt body 1, and then the spring 302 will push the fixing block 304 to pop out from the bottom of the bolt body 1, thereby limiting the nut 2 and preventing the nut 2 from falling off. When removing the nut 2, the two sets of shift blocks 305 are pushed inward at the same time, so that the shift block 305 can push the push block 303 to drive the fixing block 304 to shrink into the groove 301, and then the nut 2 can be removed. This avoids the problem that the existing nut 2 is difficult to disassemble after installation. When part of the bolt body 1 is installed and does not need to be disassembled later, the liquid glue can be pushed into the bolt body 1 through the through hole 401, so that the connection between the bolt body 1 and the plate is more firm, thereby improving the practicality of the bolt body 1.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
