Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0036] The present invention provides a stopper, comprising: a fitting area 1 and a positioning area 2 . The set area 1 is a ring structure, and has a hollow part 3 for fixing the oil valve 9, the side wall of the hollow part 3 is provided with a first contact surface, and the first contact surface is the contact surface of the oil valve 9 The hollow part 3 is detachably installed on the oil valve 9; the axis of the hollow part 3 coincides with the axis of the fitting area 1 or does not coincide. The p...

The invention provides a retainer, an anti-loosening assembly, an oil valve anti-loosening structure and an anti-loosening structure mounting method. The retainer comprises a sleeving area and a positioning area, the sleeving area is of an annular structure and is provided with a hollow part used for fixing the oil valve, and the hollow part is detachably installed on the oil valve; the positioning area is arranged in the circumferential direction of the sleeving area in a continuous or discontinuous mode, the positioning area is arranged on one side of the sleeving area, and the positioning area extends outwards in the radial direction of the sleeving area and is used for fixing the retainer. Preferably, an avoiding area is arranged on the sleeving area. The avoiding area is arranged at the top end of the sleeving area; the avoiding area is a notch, and the thickness of the notch is smaller than that of the sleeving area. The annular structure is suitable for a narrow space, the design of the avoiding area can avoid the R angle of the machine body, and the space is utilized to the maximum extent. In addition, the device also has the characteristics of simple and light structure and convenience in processing and mounting.
Description
technical field [0001] The invention relates to the field of oil supply systems, in particular to a stopper, an anti-loosening component, an oil valve anti-loosening structure and an installation method for the anti-loosening structure. Background technique [0002] The common anti-loosening methods are spring pad anti-loosening or thread adhesive anti-loosening. These two anti-loosening structures are not suitable for oil valve anti-loosening. The thread adhesive may slowly dissolve under long-term immersion in oil, causing the thread adhesive to become soft. and lapse. The anti-loose spring gasket will conflict with the gasket, destroy the sealing structure of the oil valve, and cannot be used directly. Therefore it is very necessary to develop a hexagonal head stopper anti-loosening structure suitable for small spaces. [0003] Patent document CN207470570U discloses a kind of anti-loosening bolt with manual and uniform glue coating, including: a bolt head and a screw ro...
