The third spring 408 is a pressure spring, and under the action of the third spring 408, the moving ring 407 is located near the connecting hole 401b, at this time, the whole of the pushing pin 407b is located in the clamping groove 401e, and the long rod 407a is at one end of the moving groove 401 f.
Note that the length of the pushing pin 407b matches the axial length of the locking groove 401e, so that the end surface of the pushing pin 407b is coplanar with one side surface of the chute 401c when the connection is in the initial state; the axial width of the second circular boss 301d is greater than the axial width of the clamping groove 401e, so that when the connector 401 is separated from the adapter 301, if the axial width of the second circular boss 301d is smaller than the axial width of the clamping groove 401e, the sliding block 403 is still located at the ring groove 301f, that is, when the sliding block does not pass over the second circular boss 301d, the pushing pin 407b is completely located in the clamping groove 401e, so that the pushing pin 407b pushes the insert 405 to shrink to the first cylindrical groove 403c, and the sliding block 403 does not limit the pushing pin 407b, and then rebounds into the ring groove 301f under the action of the first spring, so that the connector 401 cannot be removed.
Preferably, a connecting disc 301e is arranged on the adapter 301, a threaded hole is arranged on the connecting disc 301e, and the adapter is connected with the connecting flange through a bolt; the connecting disc 301e is provided with a radial reset groove 301g, the adapter 301 is provided with a radial positioning groove 301h, a through groove 301i is arranged between the reset groove 301g and the positioning groove 301h, the reset groove 301g, the positioning groove 301h and the through groove 301i form a U-shaped groove, and a U-shaped rod 302 is arranged in the U-shaped groove. The U-shaped rod 302 can move along the radial direction of the adapter 301, a fourth spring 303 is arranged between the U-shaped rod 302 and the side surface of the through groove 301i, the fourth spring 303 pushes one end of the U-shaped rod 302, which is positioned in the positioning groove 301h, to be exposed out of the adapter 301, and the other end of the U-shaped rod 302 is exactly tangent to the circumferential side surface of the connecting disc 301e at the moment.
It should be noted that, when the connector 401 and the adaptor 301 are mounted, the U-shaped rod 302 is located at one end of the positioning groove 301h and is exactly tangential to the end face of the connector 401, so as to prevent the connector 401 from moving axially, when the connector 401 needs to be separated from the connector 401, the screw driver or the thin rod-shaped part is used to push the U-shaped rod 302 from the reset groove 301g to completely retract into the U-shaped groove, and at this time, the connector 401 can be operated to be separated.
The working principle of the embodiment is as follows: before the connection assembly 300 and the drainage assembly 400 are assembled, namely in an initial state, under the action of the first spring 404, the end part of the slope 403a of the sliding block 403 is positioned in the connection hole 401b, the inserted rod 405 is also positioned in the first cylindrical groove 403c, the end surface of the pushing pin 407b is coplanar with one side surface of the sliding groove 401c, the connector 401 is operated to close to the adapter 301 to enable the second circular boss 301d to be embedded in the connection hole 401b and the second channel 401a during installation, the end surface of the second circular boss 301d is contacted with the slope 403a and pushes the sliding block 403 to shrink inwards of the sliding groove 401c, and when the second circular boss 301d is embedded in the second channel 401a for connection, the end of the slope 403a is embedded in the annular groove 301f when the whole sliding block 403 passes over the second circular boss 301d, the connection head 401 is limited to be separated, the installation is completed, and the second circular boss 301d pushes the moving ring 407 to enable the pushing pin 407b to be separated from the clamping groove 401 e. During disassembly, the operation connector 401 moves towards the connecting disc 301e, the slope 403a end of the sliding block 403 moves along the tapered reducing 301b, when the slope 403a passes over the tapered reducing 301b and contacts with the adapter 301, the sliding block 403 is entirely contracted into the chute 401c due to the height difference of the tapered reducing 301b, at this time, the moving distance of the sliding block 403 is the height difference formed by the tapered reducing 301b, the first cylindrical groove 403c just moves to the position of the clamping groove 401e, and one end of the inserted link 405 pops out from the first cylindrical groove 403c and is embedded into the clamping groove 401 e. At this time, since the sliding block 403 is retracted into the sliding groove 401c, the connector 401 can be operated to be separated from the adapter 301; during the separation process, since the second circular boss 301d moves to the outside of the second channel 401a, the moving ring 407 moves along with the second circular boss 301d under the action of the third spring 408, wherein when the sliding block 403 partially moves from the ring groove 301f to the second circular boss 301d, the pushing pin 407b starts to contact with the insert rod 405, and when the connecting head 401 continues to be separated, the pushing pin 407b pushes the insert rod 405 to shrink to the first cylindrical groove 403c under the action of the third spring 408, and then the sliding block 403 pops out under the action of the first spring 404, and the whole returns to the initial state.
