Abstract
Hydraulic jack base with filter is including the pedestal, being equipped with work oil cavity bottom surface and oil storage chamber bottom surface on the pedestal up end, being equipped with inlet port and draining hole on the work oil cavity bottom surface, be equipped with oil gallery and oil outlet on the bottom surface of oil storage chamber, the base is inside to be equipped with the oil feed passageway that is used for communicateing oil outlet and inlet port, and is used for communicateing the drain channel of draining hole and oil gallery, it is still including connecting in the oil outlet for the filter of impurity in the filtration fluid. The utility model has the advantages of, use on hydraulic jack the back, it is essential through the filter to get into work oil cavity's fluid from the oil storage chamber, and the impurity in the fluid is adsorbed on the filter screen, has effectively solved the impurity in the fluid and has glued on the sealed face of check valve disk seat, leads to the problem that the check valve can not normally work to the normal work of jack has been guaranteed.
Description
Technical field
This utility model relates to jack stand, a kind of jack stand with filter.
Background technology
Hydraulic jack is jacking apparatus conventional in commercial production, its internal working oil chamber is connected by the asphalt channel of chassis interior with shoe cream room, after the fluid in working oil chamber enters shoe cream room, piston component falls, realize off-load, after the fluid of shoe cream room enters working oil chamber, by piston component jacking, thus jacking weight.Being additionally provided with the oil-in connected with outside oil pump on base in working oil chamber, oil-in is connected with shoe cream room by the asphalt channel of chassis interior, is provided with ball type check valve in asphalt channel, and check valve is fitted by steel ball and sealing surface of seat and formed sealing.If being stained with impurity on sealing surface of seat, the normal sealing of check valve will be affected.But being pumped into by oil pump from shoe cream room and usually can contain impurity in the fluid working oil chamber, after using a period of time, impurity can be bonded on the sealing surface of one-way valve seat unavoidably, causes check valve cisco unity malfunction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of jack stand with filter.It solving after existing hydraulic jack uses a period of time, impurity is bonded on sealing surface of seat, the problem causing check valve cisco unity malfunction.
The technical solution of the utility model is: with the jack stand of filter, including pedestal；
Pedestal upper surface is provided with working oil chamber bottom surface and shoe cream room bottom surface, working oil chamber bottom surface is provided with fuel feed hole and oil leak hole, shoe cream room bottom surface is provided with spill port and oil outlet, chassis interior is provided with the oil inlet passage for connecting oil outlet and fuel feed hole, and for connecting the drain path of oil leak hole and spill port；
It also includes being connected in oil outlet, for filtering the filter of impurity in fluid.
The further technical scheme of this utility model is: the hole wall of oil outlet is provided with female thread, filter includes shell and the drainage screen being located in shell inner cavity, shell lower end is provided with externally threaded connector, connector communicates with shell inner cavity, having the oil through communicated with shell inner cavity on side wall of outer shell, shell is arranged in oil outlet by the external screw thread on connector.
This utility model further technical scheme is: the lower end of oil through and the distance of enclosure bottom be h, h be 1～2.5mm.
This utility model further technical scheme is: h is 2mm.
This utility model compared with prior art has the advantage that
After applying in hydraulic jack, the fluid entering working oil chamber from shoe cream room must pass through filter, impurity in fluid is attracted on drainage screen, efficiently solve the impurity in fluid to be bonded on the sealing surface of one-way valve seat, the problem causing check valve cisco unity malfunction, thus ensure that the normal work of jack.
Below in conjunction with figure and embodiment, this utility model is further described.
