Abstract
The utility model discloses a hydraulic station, and aims to solve the problems of poor dustproof effect and the like in the prior art. The hydraulic station at least comprises a working table, wherein a through hole is formed in the working table, an oil pipe is arranged in the through hole, a sealing gasket is arranged outside the oil pipe in a sleeving manner, the external diameter of the sealing gasket is larger than the diameter of the through hole, and an inner hole of the sealing gasket is in tight fit with the outer wall of the oil pipe; and a backstop part is arranged in the position, close to the table, of the oil pipe, a spring is arranged on the oil pipe between the backstop part and the sealing gasket in a sleeving manner, and the through hole is covered with the sealing gasket under the elasticity of the spring. The hydraulic station utilizes the elasticity of the spring outside the oil pipe to press the sealing gasket, so that dust can be effectively prevented from entering an oil tank, defects of the prior art are overcome, and the hydraulic station has the advantages of energy conservation and long service life.
Description
Technical field
The utility model relates to a kind of hydraulic station
Background technique
Existing hydraulic station as shown in Figure 1, generally comprise a cabinet 1, be provided with fuel tank in cabinet, cabinet is provided with table top 2, the pump housing 3 is arranged on the table top, and the fuel sucking pipe 4 of the pump housing and the through hole that passes on the table top through cooler oil outlet tube 5 are connected with fuel tank in the cabinet; By the diameter of the through hole on the table top diameter greater than fuel sucking pipe and oil outlet tube, therefore in order to prevent that dust from falling in the fuel tank by through hole, in order to avoid cause wearing and tearing and the working life of oil body and solenoid valve, can adopt following two kinds of methods to seal usually:
(1) is to make the spring rubber pad with stamping part, fixes with screw then.
(2) be to make of glass is gluing.
But, as utilize method 1, and use stamping part, to fix with screw, such labour cost is big, and material is comparatively waste also.And using method 2 is used silicon sealant, can only temporarily use some months usually, and not work under rugged environment.
The model utility content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of hydraulic station of simple in structure, good dustproof effect.
For achieving the above object, hydraulic station of the present utility model, at least comprise a table top, be provided with through hole at described table top, in described through hole, be provided with oil pipe, sheathed sealing gasket outside described oil pipe, the external diameter of described sealing gasket be greater than the diameter of through hole, the endoporus of sealing gasket and oil-pipe external wall drive fit; The position of close-table face is provided with stop member on described oil pipe, and the oil pipe between described stop member and sealing gasket is arranged with spring, overlays on the through hole at the elastic force lower seal pad of spring.
Wherein, the structure of above-mentioned stop member is: comprise a retaining ring, the sidewall of described retaining ring is provided with a screw, is provided with fastening screw trip bolt in described screw.
The utility model utilizes the elastic force of the outer spring of oil pipe to compress sealing gasket, can prevent effectively that dust from entering in the fuel tank, has overcome the defective of prior art, has energy-conservationly, and the advantage of long service life is subjected to users' favor deeply.
Description of drawings
Fig. 1 is the structural representation of hydraulic station.
Fig. 2 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1-shown in Figure 2, hydraulic station of the present utility model, at least comprise a table top 2, be provided with through hole at described table top, in described through hole, be provided with oil pipe 6, sheathed sealing gasket 7 outside described oil pipe, the external diameter of described sealing gasket be greater than the diameter of through hole, the endoporus of sealing gasket and oil-pipe external wall drive fit; The position of close-table face is provided with stop member 8 on described oil pipe, and the oil pipe between described stop member and sealing gasket is arranged with spring 9, overlays on the through hole at the elastic force lower seal pad of spring.
Wherein, the structure of above-mentioned stop member is: comprise a retaining ring 81, the sidewall of described retaining ring is provided with a screw 82, is provided with fastening screw trip bolt in described screw.Adopt such stop member, can adjust the pressure of sealing gasket easily, and dismounting is comparatively convenient.
Claims (2)
1. a hydraulic station comprises a table top at least, it is characterized in that, be provided with through hole at described table top, in described through hole, be provided with oil pipe, sheathed sealing gasket outside described oil pipe, the external diameter of described sealing gasket is greater than the diameter of through hole, the endoporus of sealing gasket and oil-pipe external wall drive fit; The position of close-table face is provided with stop member on described oil pipe, and the oil pipe between described stop member and sealing gasket is arranged with spring, overlays on the through hole at the elastic force lower seal pad of spring.
