Problems solved by technology

[0002] In the high-pressure and large-flow hydraulic system, due to the high system pressure, large flow, and large hydraulic impact force, the oil plug (process hole plug) on ​​the oil block is easy to loosen, resulting in oil leakage. Taboo: Most of the existing anti-loosening structures are complex and easy to damage, and need to be further improved

Embodiment Construction

[0016] The oil plug 1 of the present invention is screwed on the oil block 2, and the outer cover of the oil plug 1 is provided with a retaining ring 3 that interferes with the oil block 2, and the retaining ring 3 is screwed on the oil block 2; The ring 3 includes a pressure plate 31 pressed against the upper surface of the oil plug 1 ; a protruding ring 32 is protruded from the lower surface of the pressure plate 31 , and the protruding ring 32 forms a barrier to the side of the oil plug 1 .

[0017] The side of the retaining ring 3 is provided with a plurality of through-holes 33 passing through in the transverse direction, and the through-holes 33 are pierced with the screw rod 4 and pressed against the side of the oil plug 1 .

[0018] The side of the oil plug 1 is provided with a screw hole 11 corresponding to the screw 4 .

[0019] An elastic pad 5 is arranged between the protruding ring 32 and the oil plug 1 .

[0020] The working process of the present invention is...

Abstract

The invention relates to an anti-loose high-pressure oil plug. The oil plug (1) is rotatably connected to an oil path block (2), and the oil plug (1) is sleeved with a check ring (3) in contact with the oil path block (2) in an abutting manner; the check ring (3) is fixedly arranged on the oil path block (2) and comprises a pressing plate (31) compressed on the upper surface of the oil plug (1); and a protruding ring (32) is arranged on the lower surface of the pressing plate (31) in a protruding manner, and forms blocking to the side face of the oil plug (1). Through the arrangement of the check ring and the pressing plate, the pressing plate tightly presses the oil plug from the upper portion, and the pressing plate is tightly fixed to the oil path block through the check ring, so that the anti-loose effect is forcefully ensured; and due to the arrangement of the protruding ring, the protruding ring blocks the oil plug, and in the working process, the oil path cannot generate lateral movement.

Description

technical field [0001] The invention relates to an anti-loosening high-pressure oil plug, which is mainly used in high-pressure and large-flow hydraulic systems. Background technique [0002] In the high-pressure and large-flow hydraulic system, due to the high system pressure, large flow, and large hydraulic impact force, the oil plug (process hole plug) on ​​the oil block is easy to loosen, resulting in oil leakage. Big taboo: Most of the existing anti-loosening structures are complex in structure and easy to damage, and need to be further improved. Contents of the invention [0003] The purpose of the present invention is to provide an anti-loosening high-pressure oil plug with a simple structure and multiple anti-loosening structures to ensure that the oil plug does not loosen during use. [0004] For this reason, the technical solution adopted by the present invention is: the oil plug (1) of the present invention is screwed on the oil block (2), and the outer cover o...
