Mouthful, the locking mouth of lock ring is for compressing nylon tube；Lock device have structure it is simple, production cost is low, realize nylon tube fastly insert and
The purpose pulled out fastly.
Above-mentioned technical proposal is improved into one, is successively arranged lip except interior between the lock device and cavity inner face
Shape sealing ring, baffle, the first sealing ring, the second sealing ring, retainer ring, lip-type packing are limited by baffle, lip packing
Circle can be resisted against on the tube wall of nylon tube and outer tube body, and the first sealing ring and the second sealing ring are limited by the inner end of retainer ring
Position, the first sealing ring can be resisted against on the tube wall of outer tube body, and the second sealing ring can be resisted against on the tube wall of nylon tube, outside retainer ring
End face is equipped with the guide ledges of annular, and guide ledges are used to expand the bore of lock ring locking mouth；Lip-type packing and first close
The secondary seal structure that seal, the second sealing ring are constituted, is effectively prevented the problem of air pressure is revealed.
Above-mentioned technical proposal is further limited, the insulation displacement connector is circlip, and outer tube body is equipped with for assembling circlip
Annular groove；Circlip has structure simple, and production cost is low, it can be achieved that the purpose that outer tube body is inserted fastly and pulled out fastly.
Above-mentioned technical proposal is further improved, third sealing ring and are equipped at intervals on the other end of the outer tube body
Four sealing rings；Double seal ring can be effectively prevented the problem of air pressure leakage.
The utility model has the advantages that 1) lock device realizes the purpose that nylon tube can be inserted fastly, be pulled out fastly, nylon tube is without press fitting in advance to pipe
On connector, it can be assembled flexible according to field demand Fast trim nylon length of tube；2) insulation displacement connector realizes pipe fitting quick assembling
Purpose；3) the utility model is integrated with the advantages of above two air-brake gladhand, realizes the purpose of quick assembling, to mention
High production efficiency.
