The technical scheme adopted by the utility model is as follows:
the hydraulic cylinder with the dustproof mechanism comprises a hydraulic cylinder, wherein a protection cylinder is arranged at one end of the hydraulic cylinder, a slot is formed in one end of the inner side surface of the protection cylinder, a rubber sleeve is stuck in the slot, and a sealing cover is spirally arranged at one end of the protection cylinder.
Further, be equipped with the extension board in the inboard of protective cylinder and be located the one end of rubber sleeve, the extension board can restrict the angle of opening of rubber sleeve, can avoid great frictional force to cause the destruction to telescopic column and rubber sleeve.
Further, the inner side surface of the rear end of the protection cylinder is provided with the inner threads matched with the outer threads of the outer surface of the hydraulic cylinder, and the inner threads are in threaded connection, so that the installation and the disassembly are simple and convenient, and the inside of the protection cylinder is convenient to clean.
Further, the diameter of the rear end of the protective cylinder is larger than that of the front end, and the diameter of the inner side of the front end of the protective cylinder is larger than that of a telescopic column in the hydraulic cylinder by 2-5mm.
Further, the cross section of this rubber sleeve is "V" style of calligraphy structure, the one end that the rubber sleeve upper surface was declivity can be shoveled the debris that the telescopic column surface was attached.
Compared with the prior art, the utility model has the following beneficial effects:
1. when the telescopic column in the hydraulic oil cylinder stretches outwards, the rubber sleeve is extruded upwards, so that the outer surface of the telescopic column is tightly attached to the outer surface of the rubber sleeve, after the device is used, the telescopic column in the hydraulic oil cylinder contracts inwards, and meanwhile, the sundries attached to the outer surface of the telescopic column can be shoveled off by the downwards inclined end of the upper surface of the rubber sleeve, so that the telescopic column is kept clean and sanitary.
2. The sealing cover is in threaded connection with the protection cylinder, when the device is not used, the sealing cover can keep the inside of the hydraulic cylinder and the inside of the protection cylinder sealed, the protection effect can be achieved, the pollution to the telescopic column caused by dust and sundries entering the hydraulic cylinder and the inside of the protection cylinder is avoided, and when the device is used, the sealing cover only needs to be gently rotated, so that the device is simple and convenient to operate, normal use of the device is not influenced, and meanwhile the inside of the protection cylinder is convenient to clean.
3. The extension plate can limit the opening angle of the rubber sleeve, can prevent overlarge friction force between the telescopic column in the hydraulic cylinder and the rubber sleeve caused by overlarge opening angle of the rubber sleeve, can avoid the condition that the telescopic column and the rubber sleeve are damaged by larger friction force, and can prolong the service life of the device.
