As shown in Figure 6 and Figure 7, when the first contiguous block 1 is connected with the second contiguous block 2, the front end of dop 17 is arranged in the card hole of button 9, the conical surface that dop 17 front end tapering is larger contacts with the bottom margin of Ka Dong, spring now in the first contiguous block 1 and the second contiguous block 2 through hole is applied with the thrust of moving round about respectively to dop 17 and button 9, the conical surface tapering contacted with the bottom margin of Ka Dong due to dop 17 is comparatively large, and the component of spring cannot overcome friction make the Ka Dong of dop 17 and button 9 side plate depart from.
When the first contiguous block 1 and the second contiguous block 2 are by when being disconnected to connection, push button 9, inserted by dop 17 in the card hole of button 9 side plate simultaneously, then unclamp button 9, now the first contiguous block 1 and the second contiguous block 2 are in coupled condition; In emergency situations, without the need to pushing button 9, direct promotion first contiguous block 1 and the second contiguous block 2, the conical surface that now the front-end face tapering of dop 17 is less contacts with Ka Dong, because conical surface tapering is less, move until cross the maximum cross-section place of dop 17 front end on He Kadong so can promote dop 17 easily, the conical surface that then bottom margin of Ka Dong is larger with tapering on dop 17 contacts, and has now connected.
When the first contiguous block 1 and the second contiguous block 2 are by when being connected to disconnection, push button 9, now the Ka Dong of button 9 side plate does not contact with dop 17 or contacts less, under the impetus of the spring in the first contiguous block 1 and the second contiguous block 2 through hole, the first contiguous block 1 and the second contiguous block 2 are separately; In emergency situations, without the need to pushing button 9, direct pull first contiguous block 1 and the second contiguous block 2, when the component of making a concerted effort of pulling force and the first contiguous block 1 and the second contiguous block 2 through hole inner spring enough overcomes the frictional force of dop 17 with the Ka Dong of button 9 side plate, the first contiguous block 1 and the second contiguous block 2 disconnect.
The cooperation of dop and locking framework, can realize frequent plug, when there being urgency, pulls this device just can disconnect water pipe fast with certain force.
It should be noted that, the foregoing is only preferred embodiment of the present invention, instead of the restriction to technical solution of the present invention, any equivalent replacement of doing the technology of the present invention feature or corresponding improvement, still within protection scope of the present invention.
