Abstract
The utility model provides a cylinder bore ear loop for a hydraulic cylinder, which comprises a loop body. The lower end of the loop body is provided with a base formed integrally with the loop body, the distance from the lower end face of the stepped base to a loop hole center ranges from 160mm to 180mm. By the aid of integral forming, unsoldering, fracture and the like of the cylinder bore ear loop cannot be caused in use, the distance from the lower end face of the base to the loop hole center can ensure the cylinder bore ear loop to maintain the maximum stressing point all the time, and collision of the cylinder bore ear loop with other cylinder parts during use can be prevented by the aid of an arc shape on the outer lateral surface of the loop body. The cylinder bore ear loop has the maximum advantages of longer service life and avoidance of unsoldering.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, refers in particular to a kind of cylinder barrel earrings that is used for hydraulic jack.
Background technique
Be used for earrings on the hydraulic jack cylinder barrel at present and be mostly by welding again polishing form, after long-term operation, sealing-off easily between earrings ring body and the pedestal, and cause the generation of contingency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of long service life of hydraulic jack, integrated cylinder barrel earrings of being used for is provided.
For achieving the above object, technological scheme provided by the utility model is: a kind of cylinder barrel earrings that is used for hydraulic jack, and it includes ring body, and the ring body lower end is provided with integrated pedestal; Pedestal is a stepped shaft, and the distance of the stepped shaft lower end surface and the annular distance hole heart is 160 ~ 180mm.
It between described ring body and the pedestal arc-shaped transition.
The distance of the described pedestal lower end surface and the annular distance hole heart is 170mm,
Described ring body outer side surface is an arc.
Described annular distance diameter is 130mm.
Cylinder barrel earrings of the present utility model adopted one-body molded after, situation such as sealing-off can not take place, break during use, the distance of the pedestal lower end surface and the annular distance hole heart can guarantee that it remains maximum force bearing point, and the arc of ring body outer side surface can prevent that the cylinder barrel earrings from use bumping with other cylinder spare.The great advantage of this programme is: the situation of sealing-off, can not take place in long service life.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1 and accompanying drawing 2, and preferred embodiment of the present utility model is, the described cylinder barrel earrings of present embodiment includes ring body 1, and ring body 1 outer side surface is an arc, and ring body 1 lower end is provided with integrated pedestal 2; Be arc-shaped transition between ring body 1 and the pedestal 2.Pedestal 2 is a stepped shaft, and the distance of the stepped shaft lower end surface and the annular distance 3 hole hearts is 170mm, and annular distance 3 diameters are 130mm.Ring body 1 and pedestal 2 adopted one-body molded after, situation such as sealing-off can not take place, break during use, the distance of pedestal 2 lower end surfaces and the annular distance 3 hole hearts is 170mm, can make ring body 1 remain maximum force bearing point, and the arc of ring body 1 outer side surface can prevent that the cylinder barrel earrings from use bumping with other part.Adopt the working life and the practicability that can prolong the cylinder barrel earrings greatly behind the said structure.
The embodiment of the above is the preferred embodiment of the utility model only, is not to limit practical range of the present utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the present utility model.
