Detailed Description

The invention will be described in further detail below with reference to the drawings by means of specific embodiments. The description of these embodiments is provided to assist understanding of the present invention, but is not to be construed as limiting the present invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

Referring to fig. 1 and 2, a cantilever screw structure with anti-vibration and anti-loosening functions is shown.

The cantilever screw structure includes: a fixed foundation 1, a cantilever body 2, a cantilever holding seat 3, a clamp component 4, a clamp tightening component 5 and the like.

The cantilever body 2 is fixedly connected with the fixed foundation 1 in a threaded manner. The cantilever body 2 and the fixed foundation 1 form a cantilever structure.

The cantilever hugging seat 3 is positioned on the cantilever body 2 side of the fixed foundation 1. I.e. the cantilever hugging seat 3 is on the same side as the cantilever body 2 with respect to the fixed foundation 1. The cantilever clasping seat 3 is fixed on the fixed foundation 1. The cantilever hugging seat 3 hugs the cantilever body 2. The clamping force of the cantilever clamping seat 3 is provided by the clamp component 4 and the clamp tightening component 5.

Under the enclasping action of the cantilever enclasping seat 3, the integral bending resistance of the cantilever body 2 in a strong vibration environment can be improved, and the integral alternating stress is reduced, so that the strain of each part is reduced, especially the strain of the root threaded connection part of the cantilever body 2 is reduced, and the screw joint loosening prevention capability and the connection reliability of the cantilever body 2 are improved.

Further, the cantilever holding seat 3 is of a two-half symmetrical structure. Referring to fig. 3, the cantilever hug seat 3 has a hug seat lower portion 31, a hug seat upper portion 32, and a hug seat connecting portion 33 between the hug seat lower portion 31 and the hug seat upper portion 32. The hug seat lower part 31, the hug seat connecting part 33 and the hug seat upper part 32 are integrally designed. The lower part 31 of the clasping seat is fixedly connected with the fixed foundation 1. The hug seat upper portion 32 surrounds along the outer circumference of the cantilever body 2. The hug seat upper portion 32 is used for hugging the cantilever body 2. Referring to fig. 4, the clip member 4 has an omega-shaped greek letter structure. The clip member 4 has a clip main body portion 41, a left everting ear portion 42, and a right everting ear portion 43. The clamp body portion 41 surrounds the periphery of the hug seat upper portion 32. The clip tightening member 5 includes: tightening screw 51, left side pressing block 52, right side pressing block 53, tightening nut 54. The left hand press 52 is located inside the left hand valgus ear 42. The right hand press 53 is located inside the right hand valgus ear 43. The tightening screw 51 is screwed with the tightening nut 54 after passing through one wall of the left outward turning lug 42, the left pressing block 52, the other wall of the left outward turning lug 42, one wall of the right outward turning lug 43, the right pressing block 53, and the other wall of the right outward turning lug 43 from left to right. The tightening nut 54 is shifted toward the head of the tightening screw 51, so that the left-side pressing block 52 and the right-side pressing block 53 tighten the clip member 4 toward each other, thereby tightening the tightening seat upper portion 32 to the cantilever body 2.

Further, the hug base lower portion 31 abuts against the fixed base 1. The lower part 31 of the clasping seat is provided with a clasping seat connecting hole. The fixed foundation 1 is provided with a foundation connecting hole corresponding to the enclasping seat connecting hole. The clasping seat connecting hole and the foundation connecting hole jointly penetrate through a fixing screw, so that the clasping seat lower portion 31 is fixedly connected with the fixed foundation 1.

Further, the hug seat upper portion 32 has a hug seat stop ring groove 321. The clamping seat limiting ring groove 321 circumferentially surrounds. The clamping seat limiting ring groove 321 is used for accommodating the clamp component 4. That is, the clip main body 41 is abutted against the upper wall and the lower wall of the upper retainer ring groove, respectively, to thereby realize positioning in the vertical direction.

Further, the clasping seat connecting portion 33 has a truncated cone-shaped structure with a smaller upper part and a larger lower part. The above-described structure aims to improve the bending resistance and rigidity of the cantilever holding base 3 itself.

Further, the hug seat connecting portion 33 has a hug seat unloading groove 331. The hug seat unloading groove 331 extends upward to the top surface of the hug seat upper portion 32. The function of setting the enclasping seat unloading groove 331 is as follows: 1. reducing the resistance of the clamping part 4 during tightening; 2. the clasping degree and reliability of the clasping seat upper portion 32 and the cantilever body 2 are improved.

Still further, the clip tightening part 5 further includes: left bushing 55, right bushing 56. The left bushing 55 is located to the left of the left valgus ear 42. The left bushing 55 is in surface contact with the left pressure block 52. The right bushing 56 is located to the right of the right valgus ear 43. The right bushing 56 abuts against the right pressure block 53 and both are in surface contact. The aim of the structure is that: the contact stress of the left side pressing piece 52 and the right side pressing piece 53 is reduced.

The foregoing has outlined rather broadly the more detailed description of the invention in order that the detailed description thereof herein may be better understood, and in order that the present invention may be better understood. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
