Retaining ring 203 agrees with, and by squeezing pressing board 202 inwardly by ring 3 when use, while torque spring 205 opens, then by retaining ring
203 are socketed with male connector 1, then unclamp and press ring 3, and torque spring 205 bounces back, and drive pressing board 202 to laterally rotate, while retaining ring
203 are socketed with sealing ring 104, to reach sealing effect, avoid when male connector 1 is connect with female 2, not due to sealing effect
It is good, it leaks out internal oil by the gap of male connector 1 and 2 junction of female, so as to cause waste, while being unfavorable for clearing up, hold
Easily cause contingency.
The specifically used mode and effect of the present embodiment:
Whether detection device installs first, connect in use, male connector 1 is passed through public connection ring 101 with one end oil-filter pipe, together
When female 2 passed through into female connection ring 201 connect with one end oil-filter pipe, then by squeezing pressing board 202 inwardly by ring 3, together
When torque spring 205 open, then retaining ring 203 and male connector 1 are socketed, then unclamps and presses ring 3, torque spring 205 bounces back, drive
Pressing board 202 laterally rotates, while retaining ring 203 and sealing ring 104 are socketed, to be attached sealing, when cleaning, rotation is shipped and resell on another market
4,4 drive rotating plates 401 of shipping and reselling on another market rotation, when the rotation of rotating plate 401 rotates, lattice block piece 106 is contacted with rotating plate 401, and rotating plate 401 passes through anti-
External member 4011 squeezes to the right by hook 107 is covered, and spring stack 108 is shunk, while being covered 107 bottom end of hook and being lifted up, with anti-external member
4011 connections, to reach fixed fluid stopping effect, while the square-shaped slot of 105 left side central portion of jack, and 105 right side of jack is up and down
Both ends are provided with anti-off board, and jack 105 and shaft 402, it is anti-be disengaged from the groove 403 and fixed block 404 agree with so that ship and resell on another market 4 with it is public
First 1 connection is more firm, and when fixed, will ship and resell on another market 4 squeezes inwardly, and shaft 402 and fixed block 404 and jack 105 are socketed
Fixed, while the anti-setting for being disengaged from the groove 403 Yu anti-off board, can effectively avoid shipping and reselling on another market 4 falls off during rotation, is influencing equipment just
It is often used.
To sum up, although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
