DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a detachable bolt anti-vibration structure proposed by the utility model includes a bolt assembly 1, a fastening assembly 3 and a locking assembly 4. The bolt assembly 1 includes a threaded rod 102 and a slot 103. The surface of the threaded rod 102 is provided with a slot 103. Through the setting of the slot 103, one end of the threaded rod 102 can be divided into multiple groups of blades, so that each blade can have a certain deformation effect. The outer side of the threaded rod 102 is threadedly connected with a fastening assembly 3. The fastening assembly 3 includes a fastening nut 301, a limiting piece 302 and a card pile 303. The fastening nut 301 and the threaded rod 102 are screwed together. The threaded connection enables the fastening nut 301 to be threadedly sleeved on the outside of the threaded rod 102, which can facilitate the connection and fastening operation of the object. A limiting plate 302 is fixedly installed on one side of the fastening nut 301, and a clamping pile 303 cooperating with the clamping groove 103 is fixedly connected to the inner side of the limiting plate 302. By inserting the clamping pile 303 into the clamping groove 103, the clamping pile 303 can be conveniently limited by the clamping groove 103, so that the fastening nut 301 cannot be rotated, so that the fastening nut 301 can be locked, which can effectively resist the loosening caused by vibration and improve the anti-falling effect.

[0022] A locking assembly 4 is provided at one end of the threaded rod 102, and the locking assembly 4 includes a locking nut 401, an outer extrusion ring 402 and an inner extrusion ring 403. The locking nut 401 and the threaded rod 102 are threadedly connected, and the outer extrusion ring 402 and the inner extrusion ring 403 are fixedly installed on one side of the locking nut 401, respectively. The bolt assembly 1 also includes a nut 101, a screw barrel 104 and an extrusion chamber 105. The nut 101 is fixedly connected to one end of the threaded rod 102, and the screw barrel 104 is fixedly installed on the inner side of the threaded rod 102. The extrusion chamber 105 is provided between the screw barrel 104 and the threaded rod 102. The locking assembly 4 also includes a screw rod 404, and a screw rod 404 is fixedly installed on one side of the locking nut 401. The screw rod 404 and the screw barrel 104 are threadedly connected. The inner extrusion ring 403 extends into the extrusion chamber 105, so that the screw rod 404 can be inserted into the screw barrel 104, and the screw rod 404 can be tightened and tightened by rotating the locking nut 401. The threaded engagement can make the screw rod 404 extend into the screw barrel 104. At this time, the inner extrusion ring 403 can be inserted into the extrusion cavity 105. The outer portion of the inner extrusion ring 403 is in a conical shape. The diameter of one end of the inner extrusion ring 403 close to the locking nut 401 is larger than the other end. When the inner extrusion ring 403 is inserted into the extrusion cavity 105, the blades at one end of the threaded rod 102 can be squeezed, and the blades at one end of the threaded rod 102 can be expanded outward, so that the threaded rod 102 and the fastening nut 301 can be closely fitted. The extrusion force generated by the expansion can lock the fastening nut 301, so that the fastening nut 301 is not easy to loosen. Due to the friction force generated during the extrusion between the inner extrusion ring 403 and the extrusion cavity 105, the locking nut 401 is not easy to rotate and loosen, so that the locking component 4 can maintain the locking effect on the fastening component 3, so that the fastening component 3 is not easy to loosen, and can effectively resist vibration.

[0023] The outer extrusion ring 402 is connected with the limiting piece 302. When the inner extrusion ring 403 is inserted into the extrusion cavity 105, the outer extrusion ring 402 can be sleeved on the outside of the limiting piece 302. The inner cavity of the outer extrusion ring 402 is conical. The diameter of one end of the inner cavity of the outer extrusion ring 402 close to the locking nut 401 is larger than the other end. The slope in the outer extrusion ring 402 can be used to extrude the limiting piece 302. The limiting piece 302 has a deformable effect, which can make the limiting piece 302 gather inward, so that the pile 303 can be inserted into the card slot 103 for limiting, so as to achieve the locking effect of the fastening nut 301 and prevent the fastening nut 301 from loosening due to rotation. Since there is a thread between the screw rod 404 and the screw barrel 104 The meshing connection can be used to rotate the locking nut 401 by using a tool such as a wrench, so that the screw rod 404 can be separated from the screw barrel 104, and the locking nut 401 can be disassembled more conveniently, so that the inner extrusion ring 403 can be withdrawn from the extrusion cavity 105, so that the blades at one end of the threaded rod 102 can be gathered together for reset, and at the same time, the outer extrusion ring 402 can be separated from the limiting piece 302. The limiting piece 302 is made of metal and has a certain elastic effect, so that the limiting piece 302 can rebound and reset, so that the card pile 303 can be separated from the card slot 103, and the locking effect of the fastening nut 301 can be released, and the fastening nut 301 can be conveniently disassembled without destructive disassembly, which is convenient for secondary use;

[0024] A gasket 2 is sleeved on the outer side of the threaded rod 102, and a first anti-skid protrusion 201 is staggeredly distributed on one side of the gasket 2, and a second anti-skid protrusion 304 is staggeredly distributed on the other side of the fastening nut 301. The second anti-skid protrusion 304 is cooperatively connected with the first anti-skid protrusion 201, and the second anti-skid protrusion 304 can be staggeredly engaged with the first anti-skid protrusion 201. By sleeved the gasket 2 on the outer side of the threaded rod 102 and using the fastening nut 301 for tightening, the gasket 2 can be brought into contact with the object, and the gasket 2 can be squeezed by the fastening nut 301, so that the first anti-skid protrusion 201 can be staggeredly engaged with the second anti-skid protrusion 304, which can effectively increase the friction between the fastening nut 301 and the gasket 2 to avoid loosening.

[0025] The working principle of the detachable bolt anti-vibration structure based on the embodiment is as follows: by inserting the threaded rod 102 into the mounting hole in the object to be connected, the mounting hole is limited by the nut 101 so that the threaded rod 102 will not fall off, and the gasket 2 is sleeved on the outside of the threaded rod 102 so that the gasket 2 is in contact with the object. By using tools such as wrenches, the fastening nut 301 is threadedly installed on the threaded rod 102, and the fastening nut 301 is rotated to move the fastening nut 301 along the threaded rod 102 so that the fastening nut 301 is in contact with the gasket 2, and the gasket 2 can be tightened. When the fastening nut 301 is in contact with the gasket 2, the second anti-slip convex grains 304 can be staggered and meshed with the first anti-slip convex grains 201, which can increase friction and reduce looseness. By using tools such as handles to drive the locking nut 401 to rotate, the screw rod 404 can be meshed and connected with the screw barrel 104. The screw rod 404 can be inserted into the screw tube 104. At this time, the inner extrusion ring 403 can be inserted into the extrusion cavity 105, and one end of the threaded rod 102 can be squeezed, so that the blades at one end of the threaded rod 102 can collide outward with the fastening nut 301 to squeeze and tighten, thereby improving the fixing effect. At the same time, the outer extrusion ring 402 can be sleeved on the outer side of the limiting plate 302, and the limiting plate 302 can be squeezed, so that the limiting plate 302 is deformed and gathered inward, so that the clamping pile 303 can be inserted into the clamping groove 103. Through the limiting effect of the clamping groove 103 and the clamping pile 303, the fastening nut 301 can be locked, so that the fastening nut 301 will not rotate, and can resist loosening caused by vibration. By rotating the locking nut 401, it can be disassembled from the threaded rod 102, and the locking effect of the fastening nut 301 can be released, and the fastening nut 301 can be conveniently disassembled and separated, and can be conveniently reused.
