[0004] In the prior art including the above patent, the above structure is essentially a anti-disengagement nut, and the nut itself is a casting part, using the scheme shown in the prior art, the mold opening and the cost of removing burrs are relatively complicated and difficult to achieve, so how to achieve the disengagement of the screw rod nut and the nut seat is expected to be well solved. SUMMARY

[0005] The utility model aims at providing a kind of anti-loose structure of nut seat, to solve the above problems.

[0006] To achieve the above object, the utility model provides the following technical scheme:

[0007] A kind of anti-loose structure of nut seat, including body, it is set up on the body and is equipped with the installation hole for the assembly of screw rod nut, the body is fixedly provided with the elastic arch piece about the circumferential arrangement of the installation hole;

[0008] The elastic arch piece is sequentially divided into slope, slope top surface and ridge head along the rotation direction of screw cap;

[0009] The spacing between the upper surface of the ridge head and the body is greater than the spacing between the combination of the slope and the slope top surface and the body;

[0010] The slope top surface is recessed structure.

[0011] As preferred, the body is fixedly provided with the flexible elastic plate connected with the arc top of the recessed structure.

[0012] As preferred, the tough elastic plate is arranged obliquely, and the included angle between the tough elastic plate and the ridge head is obtuse, and the included angle between the slope and the top surface of the slope is acute.

[0013] As preferred, the elastic arch member is a memory elastic steel bar.

[0014] In the above technical solution, the nut seat anti-loosening structure has the following beneficial effects: during implementation, when the nut is assembled with the screw nut by threads, the nut approaches the body, the nut moves upward along the inclined surface, and then continues to approach, thereby reducing the distance between the upper surface of the ridge head and the body. Therefore, the ridge head deforms to the limit, thereby locking the nut. BRIEF DESCRIPTION OF DRAWINGS

[0020] In order to make those skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0021] As Figures 1-2 shown, an anti-loosening structure of a nut seat includes a body 1, an installation hole for assembling a lead screw nut is formed on the body 1, and elastic arch members 2 are fixedly arranged on the body 1 in a circumferential arrangement around the installation hole. The elastic arch members 2 (memory elastic steel bars) are sequentially divided into an inclined surface 21, a top surface of slope 22, and a ridge head 23 along the rotation direction of the nut;

[0022] The distance between the upper surface of the ridge head 23 and the body 1 is greater than the distance between the combination of the inclined surface 21 and the top surface of slope 22 and the body 1;

[0023] The top surface of slope 22 is a concave structure.

[0024] In the above structure, when the nut is screwed with the screw nut, as the nut approaches the body 1, the nut moves up along the inclined surface of the slope 21, and then continues to approach, so as to press the distance between the upper surface of the ridge head 23 and the body 1 to be reduced. Therefore, as the nut continues to approach, the ridge head 23 is deformed to the limit, and is inclined to the slope 21 with the concave structure as the origin, so as to lock the nut.

[0025] Further, in combination with Figure 2 As shown, the flexible elastic plate 3 is arranged in an inclined manner, and the included angle formed between the flexible elastic plate 3 and the ridge head 23 is obtuse, and the included angle formed between the flexible elastic plate 3 and the intersection of the slope 21 and the top surface 22 is acute. When the ridge head 23 is deformed to the limit state due to stress, and starts to tilt to the slope 21 with the concave structure as the deformation center point, the flexible elastic plate 3 uses its own elastic potential energy to exert a reverse resistance on the concave structure. This reverse force effectively resists the tilting trend of the ridge head 23, and further promotes the relevant components (such as the nut) to reach the locking state, and ensures the stability and safety of the structure. In short, the locking principle lies in that the flexible elastic plate 3 provides a reverse force when the ridge head is deformed through its inclined layout and elastic properties, so as to achieve stable locking.

[0026] The above only describes some exemplary embodiments of the utility model in a descriptive manner, without doubt, for ordinary skilled in the art, under the condition that the spirit and scope of the utility model are not deviated, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the utility model claims.
