The invention discloses an oil room seal device used for an oil pressure tool. A through hole is formed in a casing pipe of an oil storage barrel component, and an oil choking component is provided with an inlaid nut, a rubber oil plug and a locking and sealing component; the inlaid nut is integrally fixed when the rubber oil plug is formed; a moving screw and the inlaid nut form a screw thread pair; external threads are arranged at the right end of the moving screw, a step section with a screw shaft shoulder, a sealing ring groove matched with an O-shaped sealing ring, a smooth cylindrical section capable of being in clearance fit with a dead ring middle hole and a retaining ring groove capable of assembling nylon split washer are sequentially arranged at the left end of the moving screw, a first air path and a second path are communicated with each other and are arranged on the moving screw, and a line-shaped groove is formed in the right end of the moving screw; the moving screw penetrates through the dead ring middle hole, and the O-shaped sealing ring is arranged between shaft holes; a cone dead hole is axially positioned on the moving screw through the screw shaft shoulder and the nylon split washer. The oil room seal device used for the oil pressure tool ensures reliability of oil room sealing and accessibility of air discharging.
Description
technical field [0001] The invention relates to an oil chamber sealing device, in particular to an oil chamber sealing device for an oil pressure tool. Background technique [0002] As a hardware product, hydraulic tools are widely used, especially the automotive jack hydraulic tools used to lift vehicles are more familiar to people. However, for a long time, the problem of oil leakage at the sealing oil plug of the oil storage chamber of this oil pressure tool is ubiquitous, especially when the sealing oil plug made of this rubber material is used at a high temperature or with it. When the matching oil plug hole is relatively rough or when there are small burrs, small garbage, etc. glued to the mating position, or when the rubber oil plug is injured due to prying and deflation with a screwdriver, the hydraulic tool is on the oil plug. The phenomenon of oil leakage is relatively obvious, which makes this kind of quality assurance difficult to control, which directly affects...
