[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] Please see all drawings for this manual:

[0024] A bolt assembly includes a bolt body 1 and symmetrically arranged upper and lower washers 2 and 3. The diameter of the bolt body 1 is smaller than the diameters of the upper and lower washers 2 and 3. A nut 4 is threadedly connected to the bolt body 1. The opposing surfaces of the upper and lower washers 2 and 3 are each provided with a limiting tooth 5. The limiting tooth 5 of the upper washer 2 and the limiting tooth 5 of the lower washer 3 fit together. A plurality of positioning holes 6 are evenly arranged on the outer surface of the upper washer 2. Positioning wires 7 are fixedly installed on the bolt body 1 corresponding to the positioning holes 6. The movable end of the positioning wire 7 is provided with a color coating 8.

[0025] From the above description, it can be seen that the upper washer 2 and the lower washer 3 are placed on the bolt body 1 first, and the bolt body 1 is rotated into the corresponding object. As the rotation proceeds, the bolt body 1 first squeezes the upper washer 2, driving the limiting teeth 5 on the upper washer 2 to fit with the limiting teeth 5 of the lower washer 3 until they are completely fitted with each other, and the nut 4 is fixed and tightened at the other end; then, the positioning wire 7 is inserted into the nearest positioning hole 6 so that the color coating 8 can completely enter the positioning hole 6, and the fixation is completed.

[0026] As a technical optimization solution of the present invention, the angle of the thread on the bolt body 1 is smaller than the inclination angle of the limiting tooth 5;

[0027] From the above description, it can be seen that this angle design enables the upper washer 2 and the lower washer 3 to produce a wedge effect under the bolt body 1, does not rely on friction, has more reliable shock resistance, and the disassembly method is the same as normal nuts and bolts.

[0028] As a technical optimization solution of the present invention, a protective strip 9 is fixedly installed on the bolt body 1 corresponding to the positioning wire 7;

[0029] It can be seen from the above description that the protection strip 9 can protect the positioning wire 7 below from being broken.

[0030] As a technical optimization solution of the present invention, the upper side of the upper washer 2 and the lower side of the lower washer 3 are both provided with limiting teeth 10;

[0031] As can be seen from the above description, the second limiting tooth 10 can increase the friction between the upper washer 2 and the bolt body 1, and increase the friction between the lower washer 3 and the object being fastened.

[0032] As a technical optimization solution of the present utility model, a rotation control groove 11 is provided on the bolt body 1;

[0033] It can be seen from the above description that the rotation control groove 11 can control the rotation of the bolt body 1 through external tools, and the diversity of control also makes the use of the bolt body 1 more convenient.

[0034] As a technical optimization solution of the present invention, a trapezoidal convex ring 12 is provided on the bolt body 1 corresponding to the upper washer 2 and the lower washer 3;

[0035] From the above description, it can be seen that the design of the trapezoidal convex ring 12 can align the centers of the bolt body 1, the upper washer 2 and the lower washer 3 when tightening the bolt body 1, so that the force is more uniform.

[0036] Working principle:

[0037] First, place the upper washer 2 and the lower washer 3 on the bolt body 1, and the bolt body 1 is rotated into the corresponding object. As the rotation proceeds, the bolt body 1 first squeezes the upper washer 2, driving the limiting teeth 5 on the upper washer 2 to fit with the limiting teeth 5 of the lower washer 3 until they are completely fitted with each other, and then fix the nut 4 at the other end and rotate and tighten it; then, insert the positioning wire 7 into the nearest positioning hole 6 so that the color coating 8 can completely enter the positioning hole 6, and the fixation is completed.

[0038] The above description of the present invention and its embodiments is non-limiting. The specific embodiments shown in the specific embodiments are only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
