It can prevent loosening during equipment operation and does not affect the structural strength of the equipment.

[0043] In order to more clearly show the technical solutions provided by the present invention and the technical effects produced, the following uses specific embodiments to describe in detail the solutions provided by the embodiments of the present invention.

[0044] Embodiment 1

[0045] The following describes the use of the mechanical locking prevention device provided by the embodiment of the present invention in the locking structure with reference to the drawings.

[0046] Refer to Figures 1 - 5 As shown, the mechanical locking prevention device according to an embodiment of the present invention may include: a locking prevention gasket 1, a connecting body 4, and a locking nut 2, and may further include an auxiliary tool 6. The locking prevention gasket 1, the connecting body 4, and the locking nut 2 are all installed on the thread structure 31 of the installation body 3 to form a locking structure.

[0047] Specifically, a first groove 41 is provided in the non-main stress-bearing area outside the connecting body 4; the anti-loosening gasket 1 can be made of a metal sheet, and the anti-loosening gasket 1 is provided with a bent opening slice 11; the lock nut 2 is provided with a second groove 21, and the lock nut 2 can be made by oneself or can be a standard product; the mounting body 3 is provided with a sufficiently long threaded structure 31; the auxiliary tool 6 can be a common tool such as a drill rod, a chisel, etc.

[0049] See Figure 6 , Figure 6 In (a) of [reference], it shows a schematic diagram of the initial state before locking; Figure 6 In (b) of [reference], it shows a schematic diagram of the working state after the anti-loosening gasket is locked with the connecting body; Figure 6 In (c) of [reference], it shows a schematic diagram of the working state after the anti-loosening gasket is locked with the lock nut; Specifically, the connecting body 4, the anti-loosening gasket 1, and the lock nut 2 are sequentially inserted into the threaded structure 31 of the mounting body 3 along the X-axis direction. When installed in place, the lock nut 2, the anti-loosening gasket 1, and the connecting body 4 are tightened together by threaded connection. The opening slice 11 of the anti-loosening gasket 1 along the Z-axis direction is bent to the X-axis direction through the auxiliary tool 6, so that the opening slice 11 is embedded in the first groove 41 of the connecting body 4, ensuring that the anti-loosening gasket 1 does not rotate relative to the connecting body 4. Then, the sheet body part of the anti-loosening gasket 1 that extends along the y-axis direction beyond the lock nut 2 is bent along the x-axis direction and fits against the outer surface of the lock nut 2. At the same time, the bent sheet body part is further embedded into the second groove 21 of the lock nut 2 through the auxiliary tool 6 to finally form an inlaid anti-loosening structure 5, ensuring that the anti-loosening gasket 1 does not rotate relative to the lock nut 2. Under the pre-tightening force of the lock nut 2, the connecting body 4, the anti-loosening gasket 1, the lock nut 2, and the mounting body 3 are mutually locked. Even in extreme working conditions such as high-frequency vibration, under the action of the anti-loosening structure formed by the bent opening slice 11 of the anti-loosening gasket 1 and the first groove 41 of the connecting body 4, and the inlaid anti-loosening structure 5 formed by the remaining sheet body part of the bent anti-loosening gasket 1 and the second groove 21 of the lock nut 2, the locking between each component and the threaded structure 31 of the mounting body 3 is firm and reliable, ensuring that the entire locking structure prevents loosening and has a stable structure. Since there is no need to open a groove on the mounting body 13, the strength of the mounting body 3 is also ensured.

[0050] The function of the lock washer of the mechanical locking device in this embodiment is that it does not need to damage the shaft thread and the shaft stress structure of the installation body, does not affect the structural strength of the installation body, the locking nut is not limited to round nuts, and square nuts, polygonal nuts and self-made nuts can also be used on the locking nuts. The number of the opening slices in the lock washer is not limited and can be set according to requirements. This mechanical locking device has a simple structure, ingenious application, extremely low cost and a wide range of application equipment fields. It has the potential to become a standard part from a non-standard part. It is not only used for the anti-loosening of round nuts, hex nuts, square nuts and other self-made polygonal nuts that require locking devices, but also can be used on different forms of driving and transmission equipment such as between a fixed body and a movable body or between two movable bodies. It not only does not damage the stress structure of the shaft body, but also has a reliable anti-loosening effect to ensure the stable and safe operation of the moving equipment. The installation operation is simple, the anti-loosening function is stable and the effect is excellent. The opening slices of the anti-loosening and anti-rotation bending structure are all operated outside the device, which is easy to operate and convenient for daily observation.
