[0055] Further, if Figures 1 to 7 As shown, in this embodiment, the liquid communication device of the first embodiment of the utility model further includes: a pressure head 97, and the pressure head 97 is connected to the flow tube 5 for easy pressing.

[0056] Further, if Figures 1 to 7 As shown, in this embodiment, the liquid communication device of the first embodiment of the utility model further comprises: a through hole 98 and a sealing column 99. The through hole 98 is arranged in the pressure head 97, and the through hole 98 is connected with the flow pipe 5 to ensure the smooth flow of the liquid, and a fixing groove is arranged on the top of the through hole 98; a fixing block is arranged on the top side of the sealing column 99, and a guide surface is arranged at one end of the sealing column 99 to guide the liquid; the sealing column 99 is inserted into the through hole 98, and the fixing block and the fixing groove are clamped to fix the position of the sealing column 99 to ensure that the position of the guide surface does not move circumferentially.

[0057] Working principle:

[0058] The tail end of the locking cylinder 3 is connected to an external input pipeline, and the head end of the flow tube 5 is connected to an external output pipeline.

[0059] When docking is required, the staff presses the pressure head 97 and lifts a pair of hand ears 951 at the same time, so that the shell 95 moves upward relative to the connecting seat 7 (the third spring 96 is compressed at this time), and the arc-shaped block 953 on the inner wall of the shell 95 is no longer in the position of restricting the clamp 94, and the clamp 94 can move in the clamping groove 93, and then the second docking surface 52 is pressed down toward the first plug 2. At this time, the second plug 8 is also pressed down toward the first docking surface 12. The first plug 2 compresses the first spring 4 and no longer blocks one end of the first channel 11. The second plug 8 compresses the second spring 9 and no longer forms a block with the second docking surface 52 to block the bottom of the flow cavity 71. The sealing surface of the part, at this time, the external input pipeline, the second channel 31, the first channel 11, the circulation cavity 71, the cavity 61, the third channel 51 and the output pipeline of the external input pipeline are connected in sequence to realize the transportation of objects. At the same time, the block 92 is inserted into the annular groove 91, and the pressure head 97 is no longer pressed down, and the pair of hand-lifting ears 951 are no longer lifted, so that the shell 95 is reset under the action of the third spring 96 and moves downward relative to the connecting seat 7. At this time, the arc-shaped block 953 limits the position of the clamping member 94 again, and pushes the clamping member 94 toward the clamping edge 921 of the block 92, so as to clamp with the clamping edge 921 to complete the docking.

[0060] When docking is not needed, the staff presses the pressure head 97 and lifts a pair of carrying ears 951 at the same time, so that the shell 95 moves upward relative to the connecting seat 7 (the third spring 96 is compressed at this time), and the arc-shaped block 953 on the inner wall of the shell 95 is no longer in the position to limit the clamping member 94. The clamping member 94 can move in the clamping groove 93 and no longer clamps the clamping edge 921. Then the second docking surface 52 is separated from the first plug 2 and the second plug 8 is separated from the first docking surface 12. Under the action of the first spring 4, the first plug 2 blocks one end of the first channel 11 again. Under the action of the second spring 9, the second plug 8 forms a blocking surface with the second docking surface 52 to block the bottom of the flow cavity 71 again, thereby completing the separation.

[0061] Above, refer to Figures 1 to 7 The liquid communication device 102 according to the embodiment of the utility model is described, which is easy to disassemble and assemble, convenient to use and highly flexible.

[0064] Further, if Figures 8 and 9 As shown, in this embodiment, the barrel cover 101 with the liquid communication device 102 of the second embodiment of the utility model further comprises: a clamping groove 107 and a clamping block (not shown in the figure). The clamping groove 107 is arranged on the bottom inner wall of the storage groove 104; the clamping block is arranged on the blocking surface, and the clamping block and the clamping groove 107 are clamped, which can prevent the circumferential displacement between the liquid communication device 102 and the barrel cover 101.
