DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a fastener anti-loosening structure, comprising: a bolt 3 for fastening a first component 1 and a second component 2, the top outer walls of the first component 1 and the second component 2 are both provided with threaded through holes matched with the bolt 3; further comprising: a hexagonal snap ring 4 fixed to the second component 2, a fixing ring 5 fixed to the outer wall of the bolt 3, and anti-reversal components 6 are installed on both sides of the outer wall of the fixing ring 5, and the inner wall of the hexagonal snap ring 4 is fixed with limit teeth 7 distributed at equal distances.

[0020] In a specific application scenario, the second component 2 and the first component 1 can be combined together up and down, and the two threaded through holes can be aligned up and down. At this time, the bolts 3 can be screwed into the two threaded through holes to fix the second component 2 and the first component 1 together. In the process of the bolt 3 being continuously screwed downward, the bolt 3 will eventually press on the hexagonal retaining ring 4. At this time, the fixing ring 5 will extend into the hexagonal retaining ring 4, and the anti-reversal component 6 will also enter the hexagonal retaining ring 4. When the bolt 3 loosens and reverses in an irregular strong force fluctuation environment, the anti-reversal component 6 will be stuck on the limit tooth 7, preventing the bolt 3 from loosening and reversing, thereby playing an effective anti-loosening function.

[0021] In a preferred embodiment, the anti-reversal component 6 includes a rotating shaft 601 rotatably mounted on the outer wall of the fixing ring 5 , an arc plate 602 mounted on the outer wall of one side of the rotating shaft 601 , and an elastic member 603 connected between the arc plate 602 and the fixing ring 5 .

[0022] In a specific application scenario, when the bolt 3 becomes loose and reverses, the fixing ring 5 will reverse along with the bolt 3, thereby driving the arc plate 602 to reverse. During the reversal process, the arc plate 602 will get stuck on the limiting tooth 7, preventing the bolt 3 from reversing.

[0023] In a preferred embodiment, the elastic member 603 is two coil springs arranged up and down, and two ends of the two coil springs are connected to the outer wall of the fixing ring 5 and the outer wall of the arc plate 602 respectively.

[0024] In a specific application scenario, the elastic member 603 can provide elastic support for the arc plate 602. When the arc plate 602 rotates clockwise with the fixing ring 5 and the bolt 3, the arc plate 602 is blocked by the limiting teeth 7 to squeeze the elastic member 603, and the angle between the arc plate 602 and the fixing ring 5 becomes smaller, which does not affect the clockwise rotation of the bolt 3.

[0025] In a preferred embodiment, positioning plates 8 are fixed to the outer walls on both sides of the hexagonal retaining ring 4, and positioning holes 9 are opened on the top outer walls of the two positioning plates 8.

[0026] In a specific application scenario, it is convenient to position and fix the hexagonal clamping ring 4 on the second component 2 .

[0027] In a preferred embodiment, the first component 1 has plug rods 101 fixed at both ends of the top outer wall, and the second component 2 has plug holes 201 opened on both sides of the outer wall, and the second component 2 has positioning rods 202 fixed at both ends of the top outer wall.

[0028] In a specific application scenario, it is convenient to assemble the first component 1 and the second component 2.

[0029] In a preferred embodiment, the limiting teeth 7 are arranged obliquely.

[0030] In a specific application scenario, it is convenient to better clamp the arc plate 602 during reversal.

[0031] Working principle: The second component 2 and the first component 1 can be assembled together up and down, and the two threaded through holes can be aligned up and down. Then, the bolts 3 can be screwed into the two threaded through holes to fix the second component 2 and the first component 1 together. As the bolts 3 are screwed in continuously, the bolts 3 will eventually press on the hexagonal retaining ring 4. At this time, the fixing ring 5 will extend into the hexagonal retaining ring 4, and the arc plate 602 will also descend with the rotation and enter the spacing between the limiting teeth 7.

[0032] The elastic member 603 can play the role of elastic support for the arc plate 602. When the arc plate 602 rotates clockwise with the fixing ring 5 and the bolt 3, the arc plate 602 is blocked by the limiting tooth 7 to squeeze the elastic member 603, and the angle with the fixing ring 5 becomes smaller, which does not affect the clockwise rotation of the bolt 3. When the bolt 3 loosens and reverses, the fixing ring 5 will reverse with the bolt 3, and then drive the arc plate 602 to reverse. During the reversal process, the arc plate 602 will be stuck on the limiting tooth 7, hindering the reversal of the bolt 3, and playing an effective anti-loosening function.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
