Further, the plug cap is of a hexagonal blind nut structure.
Further, the round gasket is made of rubber.
Furthermore, the oil pipe, the blocking cap and the pipe clamp sleeve connecting piece of the hydraulic oil tank are all metal pieces.
Further, the gap between the left part and the right part of the pipe clamp sleeve connecting piece 3 is 2-10 mm.
Furthermore, the pipe clamp sleeve connecting piece does not exceed the pipe orifice of the oil pipe of the hydraulic oil tank.
The implementation method of the technical scheme comprises the following steps:
1. pressing the round gasket 2 to the root position of the blind hole of the plugging cap 1;
2. the left part and the right part of the pipe clamp sleeve connecting piece 3 are respectively wrapped on two sides of the oil pipe end;
3. the blanking cap 1 is mounted on the tubular connecting piece 3 until it is manually tightened.
The technical effects are as follows: the novel rice with the pipe orifice is realized through the rigid jacket and the flexible sealing surface; the device is simple in structure, high in usability, reliable in sealing, high in practicability and low in failure rate, and can be used for rapidly positioning and clamping a workpiece through the inner arc-shaped groove surface and the threaded structure.
