[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0018] like Figures 1 to 3The embodiment of the utility model shown preferably provides a water purifier quick-connect joint seal, including a fixed joint 1 for fixed connection to the water purifier and a connecting joint 2 threadedly sleeved on the fixed joint 1, an installation cavity 3 is formed between the fixed joint 1 and the connecting joint 2, a clamping piece 4 is arranged in the installation cavity 3, a first sealing ring 5 that can seal and abut the connection between the fixed joint 1 and the connecting joint 2 is arranged on one side of the clamping piece 4, a first clamping block 6 and a second clamping block 7 that can be elastically deformed are arranged on one side of the clamping piece 4, the first clamping block 6 can be elastically deformed and abut against the inner wall of the connecting joint 2, the second clamping block 7 can be elastically deformed and abut against the outer wall of the fixed joint 1, a locking piece 8 is threadedly sleeved on the fixed joint 1, and a convex portion 9 that can abut the first clamping block 6 and the second clamping block 7 to cause elastic deformation of the two is arranged on one side of the locking piece 8 and is located in the installation cavity 3 along the circumference.
[0019] Specifically, the locking member is pre-threadedly installed on the fixed joint, and the clamping member is inserted into the inner cavity of the connecting joint in an interference fit, and then when the connecting joint is threadedly installed on the fixed joint, as the threads between the connecting joint and the fixed joint are relatively displaced by screwing, the convex part of the locking member abuts against the first clamping block and the second clamping block of the clamping member, so that the first clamping block and the second clamping block are relatively elastically deformed and abut between the fixed joint and the connecting joint respectively, thereby realizing a clamping connection between the fixed joint and the connecting joint, thereby effectively avoiding the problem of poor stability and reliability of the threads and easy loosening.
[0020] The first sealing ring can be held by the convex part of the locking member along with the clamping member, so that the first sealing ring and the clamping member are respectively tightly abutted against the connection between the fixed joint and the connecting joint, thereby effectively enhancing the sealing between the fixed joint and the connecting joint;
[0021] And when the connecting joint and the fixed joint are completely relative to each other in thread displacement to the maximum stroke, the installation cavity formed between the connecting joint and the fixed joint leaves space for the locking member to be displaced along the axial thread of the fixed joint, and then the user can further rotate the locking member to move the convex part of the locking member to confirm that the first sealing ring is sealingly abutted against the connection between the connecting joint and the fixed joint, thereby effectively enhancing the sealing performance.
[0022] Furthermore, a cavity 10 with a trapezoidal cross section is formed between the first clamp block 6 and the second clamp block 7, and the convex portion 9 has a trapezoidal cross section and is plugged into the cavity 10. Specifically, the trapezoidal matching connection between the convex portion and the cavity can effectively drive the first clamp block and the second clamp block to elastically move away from each other and be respectively clamped between the connecting joint and the fixing joint, while the trapezoidal design can effectively reduce the friction when the convex portion is separated from the cavity.
[0023] Furthermore, a plurality of sawtooth-shaped first protrusions 11 are arranged at intervals along the height direction on one side of the first clamping block 6 for contacting the connecting joint 2. The sawtooth-shaped design allows the first clamping block to be deformed and clamped on the connecting joint at multiple points.
[0024] Furthermore, a plurality of second serrated protrusions 12 are arranged at intervals along the height direction on one side of the second clamping block 7 that abuts against the fixed joint 1. The serrated design allows the second clamping block to be deformed and clamped on the connecting joint at multiple points.
[0025] Furthermore, a connecting wall 13 is extended along the circumference of one side of the locking member 8 toward the connecting joint 2, and the connecting wall 13 is in a connection state wrapped around the outside of the connecting joint 2. A sealing cavity is formed between the connecting wall 13 and the convex portion 9, and a second sealing ring 14 is embedded in the sealing cavity. One end of the connecting joint 2 is accommodated in the sealing cavity and abuts against the second sealing ring 14. Multiple seals are formed to enhance the sealing between the connecting joint, the fixed joint and the locking member.
[0026] Furthermore, a limiting flange 15 capable of abutting against one end of the fixing joint 1 is arranged on the inner side of the connecting joint 2 .
[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model.
