DETAILED DESCRIPTION

[0037] The present invention will be described in further detail below with reference to the accompanying drawings.

[0038] Example:

[0039] Reference Figures 1-8 As shown, the utility model discloses a combined anti-loosening bolt, comprising a stud 1 and a nut 2. The nut 2 is sleeved on the outer circumference of the stud 1, and the nut 2 is threadedly connected to the stud 1.

[0040] Two first placement grooves 11 are symmetrically formed on the outer peripheral surface of the stud 1 along its axial direction, and one side of the inner wall of the two first placement grooves 11 is processed with teeth.

[0041] An anti-loosening component 3 is provided on the side of the nut 2 that penetrates toward the stud 1 .

[0042] The anti-loosening assembly 3 includes a rotating plate 32. The rotating plate 32 is rotatably mounted on one side of the nut 2. The stud 1 passes through the rotating plate 32, and the size and shape of the inner hole of the rotating plate 32 are compatible with the size and shape of the inner hole of the nut 2. An annular groove 33 is defined on one side of the nut 2, and a sliding ring 34 is provided on one side of the rotating plate 32. The sliding ring 34 is located within the annular groove 33. The vertical cross-sections of the annular groove 33 and the sliding block are both T-shaped, and the annular groove 33 matches the shape of the sliding block. The central axis of the rotating plate 32 is collinear with the central axis of the nut 2.

[0043] The size of the rotating plate 32 is slightly smaller than the size of the nut 2, that is, Figure 1 When viewed from the left side, the rotating plate 32 cannot completely block the nut 2. This is to facilitate the operator to use a tool to directly touch the nut 2, so that the nut 2 can be quickly rotated.

[0044] A second anti-slip layer 51 is provided on one side of the nut 2 where the rotating plate 32 is provided. The second anti-slip layer 51 does not contact the rotating plate 32.

[0045] Two second placement grooves 35 are symmetrically formed on one side of the rotating plate 32 away from the sliding ring 34 . Ends of the two second placement grooves 35 away from the stud 1 both pass through the rotating plate 32 .

[0046] A clamping plate 31 is provided at each of the two second placement slots 35 .

[0047] The card plate 31 includes a first sliding block 311 and a vertical plate 312. The first sliding block 311 is located at the second placement groove 35, and the first sliding block 311 is slidably connected to the second placement groove 35.

[0048] The vertical cross-sections of the first sliding block 311 and the second placement slot 35 are both T-shaped. The vertical plate 312 is fixedly mounted on the corresponding first sliding block 311. The vertical plate 312 is always located outside the rotating plate 32. The side of the vertical plate 312 near the stud 1 is machined with teeth.

[0049] The width of the vertical plate 312 matches the width of the first placement groove 11 .

[0050] When one end of the first sliding block 311 contacts one side of the inner wall of the corresponding second placement groove 35, the teeth on the vertical plate 312 engage with the inner teeth of the corresponding first placement groove 11, and part of the vertical plate 312 is located outside the stud 1. In addition, the surface of the end of the first sliding block 311 away from the stud 1 is coplanar with the surface of the outer peripheral surface of the rotating plate 32.

[0051] Part of the vertical plate 312 is located outside the stud 1 to increase the overall strength of the clamping plate 31 and improve its service life. The anti-loosening assembly 3 also includes a stopper assembly 4, which secures the two clamping plates 31 in position. The stopper assembly 4 includes a stopper ring 41, which is sleeved onto the outer circumference of the rotating plate 32 and threadedly connected to the rotating plate 32. The inner wall of the stopper ring 41 mates with one end surface of the two first sliding blocks 311.

[0052] The first anti-slip layer 5 is provided on one side of the limiting ring 41 close to the nut 2. When the limiting ring 41 is arranged on the outer circumference of the rotating plate 32 and covers one end of the two first sliding blocks 311, the first anti-slip layer 5 is in contact with the second anti-slip layer 51.

[0053] The implementation principle of the above embodiment is:

[0054] The stud 1 passes through the object, and the operator screws the nut 2 onto the stud 1. After the nut 2 is screwed in.

[0055] The operator rotates the rotating plate 32 so that the two second placement grooves 35 on the rotating plate 32 face the corresponding first placement grooves 11 .

[0056] Next, the operator inserts the card plate 31 into the second placement slot 35 and pushes the card plate 31 to move. When the card plate 31 can no longer move, the teeth on the vertical plate 312 engage with the teeth on the corresponding first placement slot 11.

[0057] The operator maintains the position of the clamping plates 31 and screws in the retaining ring 41. Since the position of the rotating plate 32 is now limited by the two clamping plates 31, the rotating plate 32 cannot rotate freely. By screwing in the retaining ring 41, the position of the two clamping plates 31 is fixed, preventing them from moving.

[0058] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
