Abstract
The invention discloses a manual oil pump of an oil jack. The manual oil pump of the oil jack comprises a pump body and a pump core. A pump core installation hole is formed in the upper end of the pump body. An O-type seal ring, a nylon check ring, a pump bush and a Y-type seal ring are sequentially arranged between the pump core installation hole and the pump core from bottom to top, and are respectively connected with the lower end of the pump core in a sleeved mode. The lower end of the pump core is inserted into the pump core installation hole. By adopting the technical scheme, the O-type seal ring, the nylon check ring, the pump bush and the Y-type seal ring are sequentially arranged between the pump core installation hole and the pump core from bottom to top, the O-type seal ring and the Y-type seal ring are used at the same time, so that the sealing performance is good, and the Y-type seal ring is good in pressure resistance and abrasion resistance, low in cost, stable in work and long in service life.
Description
Technical field
The present invention relates to technical field of jacks, be specifically related to a kind of oil jack hand oil pump.
Background technology
The seal ring that the pump core of prior oil pressure jack hand oil pump uses is O RunddichtringO and back-up ring, and the O RunddichtringO is expensive, and wear-resisting resistance to pressure is poor, because the continuous up-and-down movement of pump core, the O RunddichtringO weares and teares easily, and service life is short.
Summary of the invention
At the deficiency that prior art exists, the object of the present invention is to provide a kind of reasonable in design, seal ring resistance to abrasion good, working stability, cost is low, the oil jack hand oil pump of long service life.
For achieving the above object, the invention provides following technical scheme: a kind of oil jack hand oil pump, comprise the pump housing and pump core, described pump housing upper end is provided with pump core mounting hole, be disposed with O RunddichtringO, nylon back-up ring, pump block and y-type seal ring between described pump core mounting hole and the pump core from the bottom up, described O RunddichtringO, nylon back-up ring, pump block and y-type seal ring respectively with the lower end socket of pump core, insert in the pump core mounting hole described pump core lower end.
By adopting technique scheme, be disposed with O RunddichtringO, nylon back-up ring, pump block and y-type seal ring between pump core mounting hole and the pump core from the bottom up, O RunddichtringO and y-type seal ring have been used simultaneously, good seal performance, the withstand voltage resistance to abrasion of y-type seal ring is good, cost is low, working stability, long service life.
The present invention further is provided with: described pump core upper end one side is provided with U-shaped open slot, and corresponding open slot is provided with pump core pin, is provided with near pump core upper end and presses hand, and described pump core pin inserts in the open slot, makes the pump core and press hand hinged by pump core pin.By this setting, the pump core is with to press hand easy to connect, reliable.
The present invention also further is provided with: described press the hand front end and the pump housing hinged, press the hand rear end handle that has been threaded, described handle rear end is socketed with taper knob.By this setting, structure of the present invention is more reasonable, and it is more reliable to work.
Advantage of the present invention is: compared with prior art, structure setting of the present invention is more reasonable, be disposed with O RunddichtringO, nylon back-up ring, pump block and y-type seal ring between pump core mounting hole and the pump core from the bottom up, O RunddichtringO and y-type seal ring have been used simultaneously, good seal performance, the withstand voltage resistance to abrasion of y-type seal ring is good, and cost is low, working stability, long service life.
The invention will be further described below in conjunction with Figure of description and specific embodiment.
