Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 to 2, the present invention provides a self-adjusting locking mechanism 100, including: a central shaft 10; a U-shaped gasket 11 sleeved on the central shaft 10; the sleeve 12 is sleeved on the central shaft 10 and connected with one end of the U-shaped gasket 11; the end cover 13 is sleeved on the central shaft 10 and connected with the other end of one end of the U-shaped gasket 11 connected with the sleeve 12; the central shaft 10 is provided with a clamping groove for sleeving a U-shaped gasket 11.

It can be understood that, in the working process of the conventional brake, because the conventional brake is in the working conditions of impact and vibration for a long time, the friction force between the thread pairs in the self-adjusting locking mechanism which is fixedly locked through the threads can be gradually reduced, and the threads are gradually loosened, so that the relative positions of the internal parts of the self-adjusting mechanism are changed, the self-adjusting function is influenced, and the service life of the brake is further shortened. The self-adjusting mechanism is structurally improved, so that the parts sleeved on the central shaft 10 are prevented from axial displacement, and the service life of the brake is prolonged.

Specifically, in the self-adjusting locking mechanism 100 provided by the present application, a clamping groove is provided on the central shaft 10, and is used for the U-shaped gasket 11 to be sleeved at the position of the clamping groove. It can be understood that the U-shaped gasket 11 is clamped in the clamping groove formed in the central shaft 10, that is, the positions of the U-shaped gasket 11 and the central shaft 10 are kept unchanged, so that the limiting function is achieved.

It should be noted that the gasket disposed at the central groove is preferably a U-shaped gasket 11, which is considered to effectively reduce the time for assembling and disassembling the U-shaped gasket 11 during the assembling or disassembling process. It will be appreciated that the shims disposed at the central slot may also be circular shims. In a preferred embodiment provided herein, a U-shaped shim 11 is preferably used.

And the sleeve 12 is sleeved on the central shaft 10 and connected with one end of the U-shaped gasket 11. The sleeve 12 is sleeved on the central shaft 10 and connected with one end of the U-shaped gasket 11, namely, one end of the sleeve 12 is in contact with the end face of one end of the U-shaped gasket 11. It can be understood that one end of the sleeve 12 contacts with the end surface of one end of the U-shaped gasket 11, and since the position of the U-shaped gasket 11 and the central shaft 10 is fixed, the position of the sleeve 12 contacting with the end surface of one end of the U-shaped gasket 11 is relatively fixed.

It should be noted that the sleeve 12 described herein is the sleeve 12 that is sleeved on the central shaft 10. The sleeve 12 may be in the form of a hollow cylinder or may be in the form of a hollow disk stacked by at least two cylindrical features. In a preferred embodiment provided herein, the sleeve 12 is sleeved onto the central shaft 10 preferably using two hollow discs stacked in a cylindrical configuration.

It should also be noted that the end of the sleeve that is connected to the U-shaped gasket may be end-to-end or may be fully inserted into the female end cap. It will be appreciated that the U-shaped gasket is fully embedded in the female end cap in the connected state, preventing the U-shaped gasket from radially disengaging.

And the end cover 13 is sleeved on the central shaft 10 and connected with the other end of one end of the U-shaped gasket 11 connected with the sleeve 12. It will be appreciated that the end cap 13 described herein may be replaced by other components that interface with the sleeve 12 within the brake. The sleeve 12 is connected at one end to the U-shaped washer 11 and at the other end to the end cap 13, i.e. the end cap 13 holds the sleeve 12 in a defined position in the central shaft 10.

In another embodiment, the self-adjusting locking mechanism 100 further includes an elastic member 14 sleeved on the central shaft 10 and connected to the sleeve 12 and the end cap 13. It will be appreciated that, without the provision of the elastic member 14, the self-adjusting locking mechanism 100 may have a certain axial displacement after a certain period of operation, whereas with the provision of the elastic member 14, a certain axial pressing force is provided to the parts connected to the elastic member 14, while a certain axial pressing force is provided to the parts connected to the elastic member 14, which are not connected to the elastic member 14, i.e. a good self-adjusting function of the self-adjusting mechanism is ensured. It is to be understood that the axial contact pressure referred to here is to be understood as an axially floating contact pressure.

In another embodiment, the resilient member 14 is partially disposed within the sleeve 12. In particular, the elastic member 14 is connected to the sleeve 12 and the end cap 13. The connection between the elastic element 14 and the sleeve 12 may be that the elastic element 14 is connected with the end surface of the sleeve 12, or the elastic element 14 is partially arranged in the sleeve 12. In a preferred embodiment provided herein, the resilient member 14 is preferably disposed partially within the sleeve 12. It will be appreciated that the resilient member 14 may be provided partially within the sleeve 12, with the resilient member 14 being provided in a longer length of the resilient member 14 than would be provided between the end face of the sleeve 12 and the end face of the end cap 13. It should also be noted that the elastic member 14 is partially disposed in the sleeve 12, and the elastic member 14 may be partially disposed in the sleeve 12 or may be integrally disposed in the sleeve 12.

In another embodiment, the elastic member 14 includes at least a spring. It should be noted that the elastic member 14 may be a spring, or may be a rubber material having elasticity. In a preferred embodiment provided herein, the resilient member 14 is preferably a spring.

In another embodiment, the axial width of the slot formed in the central shaft 10 is greater than the thickness of the U-shaped gasket 11. It can be understood that the axial width of the clamping groove is larger than the thickness of the U-shaped gasket 11, so that the U-shaped gasket 11 can be conveniently clamped in the clamping groove. It can be understood that, in the self-adjusting mechanism, one end of the elastic member 14 is connected with the end cover 13, and the other end is connected with the sleeve 12, the elastic member 14 will give an axial pressure to the sleeve 12, and further the sleeve 12 gives a certain axial pressure to the U-shaped gasket 11, and then it can be understood that the U-shaped gasket 11 has a certain position with the clamping groove of the central shaft 10. It should also be noted that the axial width of the slot is greater than the thickness of the U-shaped shim 11, and may be such that the difference between the axial width of the slot and the thickness of the U-shaped shim 11 is between 0.2 mm.

The present application further provides a brake (not shown) comprising a self-adjusting locking mechanism 100; and the braking device is connected with the self-adjusting locking mechanism.

Specifically, the improved self-adjusting locking mechanism 100 is applied to an existing brake, that is, a brake device is connected with the self-adjusting locking mechanism 100 to form the brake. The axial displacement of the internal parts of the self-adjusting locking mechanism 100 can be effectively limited through the brake, and the permanent anti-loosening can be realized; the disassembly and assembly are convenient, and the looseness prevention of the original mechanism cannot be influenced by repeated disassembly and assembly; the good self-adjusting function of the brake is ensured, and the service life of the brake assembly is prolonged.
