Description

Quick release connector

The invention relates to a quick release joint.

Press, in order to facilitate the quick disassembly and assembly of the oil line pipeline, it uses the way of pushing the ball to interlock with the card slot for quick-release fixing. The switch between the ball and the card slot is mainly through a The outer kit is pushed and pulled to assemble or release the tubing. However, because the outer kit is only fixed by a spring, it is easy to lose the fixing effect and loosen the tubing due to the elastic fatigue of the spring. In addition, the outer sleeve It is also very easy to cause the oil pipe to fall off due to an unintentional push and pull, resulting in serious consequences such as oil body leakage and failure of the brake device. Therefore, there is a joint through the screw lock method disclosed in the patent number TWM466864 to avoid the loosening of the tubing. However, the working time of the screw lock disassembly and assembly is too long, and the screw lock may not be tightened without the assistance of appropriate tools. And failure, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive quick-release connector to solve the above problems.

In this embodiment, there are two second notches 32, wherein when the flange 42 is inserted into the ring wall 41 and the flange 42 rotates relative to the ring wall 41 in the axial direction 11 to the second position, the ring wall 41 is inserted into the two second notches 32, in this embodiment the flange 42 has two fins 421 protruding and extending on opposite sides in the radial direction, and the second gaps 32 are respectively provided on the opposite sides in the radial direction of the ring wall 41, when the flange 42 is opposite the ring wall 41 in the first In position, the two notches correspond to the two fins 421 of the flange 42, and the flange 42 can be inserted into or detached from the ring wall 41. The quick release connector further includes an elastic member 12 that elastically abuts on one of the first connector 2 and the second connector 3 to connect one of the first kit 21 and the second kit 31 Springing in the direction of the other, in this embodiment, the elastic member 12 is disposed on the second joint 3 and the second set 31 is springed in the direction of the first set 21, when the ring wall 41 is opposed When the flange 42 is rotated to the second position along the axial direction 11, the two second notches 32 of the second kit 31 are sleeved into the ring wall 41 to prevent the ring wall 41 from rotating relative to the flange 42 Therefore, the ring wall 41 is separated from the flange 42.

Preferably, each of the first notch 44 and each of the second notch 32 is provided with an oblique edge 321, 441 obliquely to the axial direction 11 at both ends of the axial direction 11, so when the ring wall 41 is inserted into the When two second notches 32 (as shown in FIG. 6), a strong external force can be applied, and each of the first notch 44 and the beveled edges 321, 441 of the second notch 32 can be pushed against each other to make the The second set 31 slides away from the first set 21.

In addition, the second set 31 has a pair of non-circular perforations 311 corresponding to the shape of the flange 42. The non-circular through holes 311 are sleeved on the flange 42 to prevent the second set 31 from rotating relative to the second joint 3.

It should be noted that one of the first joint 2 and the second joint 3 is provided with a large diameter section 24 and the other is provided with a small diameter section 34. When the flange 42 is inserted into the ring wall 41, the small The diameter section 34 is also inserted into the large diameter section 24, so that the first pipeline 23 communicates with the second pipeline 33, and prevents liquid leakage from between the first pipeline 23 and the second pipeline 33. Preferably, the inner wall of the large-diameter section 24 can be provided with an O-ring 241 to have a more sealing effect.

It is worth mentioning that the first pipeline 23 and the second pipeline 33 are respectively provided with an accommodating groove 25, 35, and the two accommodating grooves 25, 35 are respectively accommodated with a resilient member 5, which is The member 5 normally abuts in the facing direction along the axial direction 11 to close the notch facing the two accommodating slots 25, 35. In this embodiment, the resilient member 5 includes a sealing card Bead and a spring, so when the first joint 2 and the second joint 3 are connected, liquid leakage can be prevented, and when the small-diameter section 34 is inserted into the large-diameter section 24, the two elastic resisting pieces 5 resist each other At the top, the two resilient pieces 5 are away from the two notches, respectively, so that the first pipeline 23 and the second pipeline 33 communicate with each other.

In summary, the quick-release joint of the present invention can quickly disassemble and assemble the first joint and the second joint, and when the first joint and the second joint are assembled, the first joint and the second joint can be effectively prevented The joints are accidentally loosened, so fluid leakage can be avoided.
