[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the attached drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by showing examples of the present invention.
[0019] As Figure 1 As shown, the present invention provides a technical solution for a loosening prevention fastener: including a bolt body 1 and a nut 2, the nut 2 is threadedly connected to the bolt body 1. When in use, the user inserts the bolt body 1 through a preset position, and then turns the nut 2 to make the nut 2 abut against the installation position to achieve the fastening function.
[0020] In this embodiment, a first gasket 3 is integrally formed and installed on the bottom surface of the nut 2. The shape of the first gasket 3 is circular. The first gasket 3 is located between the nut 2 and the installation position, playing a role in relaxation and reducing the spontaneous movement of the nut 2.
[0021] In this embodiment, in this example, a plurality of fixing rings 4 are integrally formed and installed on the circumferential side of the first gasket 3. The plurality of fixing rings 4 are arranged along the circumferential direction of the first gasket 3. When using the nut 2, the staff pre-drills a fifth threaded hole at the using position, and makes the plurality of fixing rings 4 correspond to the plurality of fifth threaded holes one by one. At the same time, a fixing member 5 is detachably installed in the plurality of fixing rings 4, and the inner ends of the plurality of fixing members 5 are respectively threadedly connected in the plurality of fifth threaded holes, so as to improve the connection strength between the nut 2 and the installation position, and further reduce the possibility of loosening between the nut 2 and the bolt body 1.
[0022] Among them, the fixing member 5 is a screw rod, and the plurality of screw rods are respectively threadedly connected in the plurality of fixing rings 4.
[0023] In this example, a limiting sleeve 6 is integrally formed and installed on the side of the first gasket 3 away from the bolt body 1. The staff pre-drills a limiting hole adapted to the limiting sleeve 6 at the installation position. When installing the first gasket 3, the user inserts the limiting sleeve 6 into the limiting hole, and the limiting sleeve 6 plays a guiding role in the installation of the first gasket 3.
[0024] In this example, two through holes 7 are symmetrically opened on both sides of the bolt body 1. The two through holes 7 are horizontally opened. At the same time, mounting rods 8 are installed in the two through holes 7, and a bracelet 9 is installed at the outer ends of the two mounting rods 8. When rotating the bolt body 1, the user holds the bracelet 9, which is convenient for the user to turn the bolt body 1.
[0025] In this example, a second gasket 11 parallel to the first gasket 3 is threadedly connected to the bolt body 1. The second gasket 11 and the first gasket 3 clamp the installation position, reducing the situation that occurs between the bolt body 1 and the installation position.
[0026] In this example, a second limiting sleeve 12 is integrally formed and installed on the side of the second gasket 11 away from the bolt body 1. The limiting sleeve 6 is parallel to the second limiting sleeve 12. When installing the second gasket 11, the user inserts the second limiting sleeve 12 into the first limiting hole, and the limiting sleeve 6 plays a guiding role in the installation of the second gasket 11.
[0027] Refer to Figure 2 , in the example, the difference from the example is that a plurality of threaded holes 13 are opened on the top surface of the second limiting sleeve 12, and one end of each of the plurality of fixing members 5 passes through the preset fifth threaded hole and is threadedly connected in the corresponding threaded hole 13, further providing the connection strength between the nut 2 and the installation position.
