By above-mentioned setting, effectively connector cover can be connected with connectedness by screw thread, and clamp lid and company
Sealing ring between parts improves sealing performance, and connects more convenient operation.
The utility model is further arranged: being provided with sealing ring between the connector cover and the connectedness.
By above-mentioned setting, sealing function is played in the gap that sealing ring can dock between skull and connectedness, works as connector cover
When being tightened with connectedness by screw or screw thread, sealing ring can be further improved sealing effect.
The utility model is further arranged: the top margin is provided with dotted convex in the side contacted with the first seal
It rises.
By above-mentioned setting, when clamp cover when, the dot bulge of top margin can increase the preload of first seal
Power prevents first seal from loosening and reinforcing the sealing performance of first seal.
The use of the new type is further arranged: the joint body is fixed with outer-hexagonal head.
By above-mentioned setting, when connecting hydraulic tube and joint body, because joint body can rotate, spanner is puted forth effort
Point cannot be arranged on connectedness, and outer-hexagonal head is provided on joint body then and can be convenient connection hydraulic tube and connector sheet
Body.
In conclusion the utility model has the following beneficial effects:
The metal of the utility model and elastic liquid compound seal flared fitting, by being fixed with ball in joint body
Head, bulb are rotatablely connected by connector cover and connectedness, under the premise of ensure that pipeline connection, are limiting flared fitting
It can be freely rotated in angle processed, improve the operating condition adaptability of flared fitting, use is more convenient, and reduces
Hydraulic tube to the bending stress of flared fitting, extends the service life of flared fitting in that case of ben.
