[0026] First Embodiment

[0027] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a corrosion-resistant and shock-resistant fastener provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the bolt mechanism. A corrosion-resistant and shock-resistant fastener includes: a bolt mechanism 1, wherein the bolt mechanism 1 includes a threaded body 11, and a locking interface 13 is connected to the surface of the threaded body 11;

[0028] Anti-loosening mechanism 2, the anti-loosening mechanism 2 includes elastic element 21, the elastic element 21 is used for connecting and fixing the nut and the threaded body 11;

[0031] The card interface 13 is square-shaped and is located on the surface of the threaded body 11, and is on the same straight line. The function of the anti-loosening mechanism 2 is to fix the nut and prevent the nut from loosening due to vibration. There are two elastic members 21, which can be spring steel, titanium alloy and engineering plastic, preferably engineering plastic. The function of the position adjustment mechanism 3 is to adjust the position of the anti-loosening mechanism 2. The moving member 32 is round and can be embedded in the inside of the threaded body 11. The function of the pulling mechanism 4 is to pull the elastic member 21 to disengage it from the nut. There are two steel wires 44, one end of which is fixedly connected to the surface of the two elastic members 21 respectively.

[0032] A bolt head 12 is fixedly connected to the top of the threaded body 11, and a snap-fit ​​member 22 is connected to the top of the elastic member 21. The snap-fit ​​member 22 is used to snap with the nut to fix the nut.

[0033] The bolt head 12 is hexagonal, and the snap-fit ​​part 22 is a circular block with a toothed surface array. It is connected to the other end of the two elastic parts 21 respectively. When the elastic part 21 moves to the snap-fit ​​interface 13, the elastic part 21 is disengaged from the inner surface of the threaded body 11 and pops outward. The teeth of the snap-fit ​​part 22 are engaged in the nut thread, thereby preventing the nut from loosening.

[0034] The threaded body 11 is internally connected to a screw 31, the surface of the moving part 32 is connected to a first limiting member 33, and the inner surface of the threaded body 11 is connected to a second limiting member 34. The first limiting member 33 and the second limiting member 34 are connected to limit the movement of the moving part 32.

[0035] The screw 31 is rotatably connected inside the threaded body 11, and a rotating block is connected to its top. The moving part 32 is threadedly connected to the surface of the screw 31. There are two first limiting parts 33 and two second limiting parts 34. The first limiting part 33 can be a slider or a groove, preferably a slider. The two first limiting parts 33 are fixedly connected to the surfaces at both ends of the moving part 32. The two second limiting parts 34 can be sliders, grooves or rods, preferably grooves. They are respectively opened on the inner surfaces at both ends of the threaded body 11. The two first limiting parts 33 are slidably embedded inside the two second limiting parts 34.

[0036] The bolt head 12 is internally connected to a winding member 41 and a first tightening member 42, and the threaded body 11 is internally connected to a second tightening member 43 near the top. The steel wire 44 is movably connected to the surfaces of the winding member 41, the first tightening member 42 and the second tightening member 43.

[0037] There are two of each of the following: the winding member 41, the first tightening member 42, and the second tightening member 43. Both winding members 41 and the two first tightening members 42 are connected to the inner surface of the bolt head 12. The winding member 41 can be a rotating rod or a rotating disk, preferably a rotating rod. The first tightening member 42 and the second tightening member 43 can be guide rods or guide blocks, preferably guide rods.

[0038] The winding member 41 is used to wind up and prevent loosening of the steel wire 44, and the first tightening member 42 and the second tightening member 43 are used to tighten and guide the steel wire 44.

[0039] Two second tightening members 43 are fixedly connected to the inside of the threaded body 11 near the top. The other ends of the two steel wires 44 are wound on the surface of the winding member 41 and connected to the surfaces of the first tightening member 42 and the second tightening member 43.

[0040] The working principle of the corrosion-resistant and shock-resistant fastener provided by this utility model is as follows:

[0041] During installation, first, threaded body 11 is passed through the interior of the object, and then the nut is threaded into the surface of threaded body 11. After fixing, screw 31 is rotated. The first limiting member 33 and the second limiting member 34 are connected and limited, and the moving member 32 drives the anti-loosening mechanism 2 to move upward until the elastic member 21 reaches the locking interface 13. It disengages from the resistance of the inner surface of threaded body 11, and the locking member 22 pops out through the locking interface 13 and engages with the threaded surface of the nut. At this time, screw 31 cannot rotate. When threaded body 11 is vibrated, the locking member will engage. The fastener 22 secures the nut, preventing it from loosening. When maintenance or replacement is required, the lubrication mechanism 5 is clamped and rotated by the caliper. At this time, the winding member 41 rotates to wind up the steel wire 44, which in turn pulls the elastic member 21 inward. The clamping member 22 is no longer connected to the nut. Then, the screw 31 is rotated in the opposite direction. At this time, the moving member 32 drives the anti-loosening mechanism 2 to move downward until the elastic member 21 is completely embedded in the threaded body 11 at the bottom of the clamping interface 13. Then, the nut can be unscrewed using a tool.

[0042] Compared with related technologies, the corrosion-resistant and shock-resistant fastener provided by this utility model has the following beneficial effects:

[0043] This utility model provides a corrosion-resistant and shock-resistant fastener. The anti-loosening mechanism 2 can be moved and engaged with the nut by the position adjustment mechanism 3 to fix the nut and prevent the risk of the nut from loosening due to vibration. At the same time, the elastic element 21 can be pulled by the pulling mechanism 4 to disengage it from the nut, so that the nut can be disassembled for easy maintenance and replacement in the future.

[0044] Second Embodiment

[0045] Please refer to the following: Figure 3 Based on the corrosion-resistant and shock-resistant fastener provided in the first embodiment of this application, the second embodiment of this application proposes another corrosion-resistant and shock-resistant fastener. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0046] Specifically, the second embodiment of this application provides a corrosion-resistant and shock-resistant fastener that differs in that the threaded body 11 is provided with a lubrication mechanism 5. The lubrication mechanism 5 includes an oil inlet 51, a sealing plug 52, an oil delivery chamber 53, and a lubrication port 54. The oil inlet 51 is connected to the bottom of the threaded body 11, the sealing plug 52 is embedded inside the oil inlet 51, the oil delivery chamber 53 is opened inside the threaded body 11, and the lubrication port 54 is connected to the surface of the threaded body 11.

[0047] There are multiple oil delivery chambers 53, and one end of each is connected to the oil inlet 51. The lubrication port 54 is connected to the inside of the thread groove on the surface of the thread body 11 and is connected to the oil delivery chamber 53. There are multiple lubrication ports 54, and the oil can flow into the thread groove at different positions through the lubrication port 54.

[0048] The working principle of the corrosion-resistant and shock-resistant fastener provided by this utility model is as follows:

[0049] When lubrication is required, the sealing plug 52 is removed from the oil inlet 51, and then the oil supply equipment connecting pipe is connected to the oil inlet 51 to supply oil into the refrigerator sealing plug 52. The lubricating oil enters the sealing plug 52 and flows through the lubrication port 54 to the thread gap of the threaded body 11 and the nut for lubrication.

[0050] Compared with related technologies, the corrosion-resistant and shock-resistant fastener provided by this utility model has the following beneficial effects:

[0051] This utility model provides a corrosion-resistant and shock-resistant fastener. While oil is supplied to the inside of the threaded body 11 through the oil inlet 51, it can also be delivered through the oil delivery chamber 53, so that the lubricating oil flows from each lubrication port 54 into the thread gap between the threaded body 11 and the nut to achieve lubrication and prevent the threaded body 11 from rusting and becoming unremovable.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
