DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figures 1 to 3 , an air delivery pipeline connection device, comprising:

[0029] The ferrule 1 is a flexible cylinder made of a flexible material, and a slit is provided in the ferrule 1 for the locking device to pass through;

[0030] The ferrule is made of double-layer fabric and is used to wrap the locking device and seal the seams at the connection of the air supply pipeline;

[0031] A locking device, wherein the locking device is arranged inside the ferrule 1, and both ends of the locking device are located outside the ferrule 1;

[0032] The two ends of the locking device are respectively provided with a lock buckle and a lock tongue, the lock tongue can be inserted into the lock buckle, and the lock buckle and the lock tongue are cooperatively connected;

[0033] The lock buckle is used to drive the lock tongue to move in the lock buckle, so as to adjust the diameter of the locking device.

[0034] The locking device includes: a rope structure 2, the rope structure 2 is arranged inside the ferrule 1, and both ends of the rope structure 2 extend out of the ferrule 1 and are located outside the ferrule 1;

[0035] The lock buckle and the lock tongue structure are respectively installed at both ends of the rope structure 2; the rope structure is a steel wire rope, and the number of steel wire ropes is not limited, and multiple steel wire ropes can be set according to actual conditions;

[0036] The locking structure includes a sleeve 4, which is fixedly connected to one end of the rope structure 2. The bottom of the sleeve 4 is sealed. A screw is rotatably connected inside the sleeve 4. A gap is left between the screw and the inner wall of the sleeve 4. One end of the screw is set through the sleeve 4.

[0037] The lock tongue is a rack 3 with a long sheet structure and a thread. The thickness of the lock tongue is adapted to the spacing. The threaded surface of the lock tongue faces the screw and meshes with the screw. The teeth of the rack are helical teeth, and the threads on the screw are helical threads that mesh with the teeth.

[0038] The end of the screw rod located outside the sleeve 4 is provided with a knob, and the end of the knob is provided with any one of a slot, a cross slot and a hexagonal slot.

[0039] To operate the connection device, place the ferrule on the connection point of the pipe, then align the end of the rack with the gap between the screw and the sleeve. Turn the knob to drive the screw, allowing the rack to pass through the sleeve. This allows the size of the circular loop formed by the wire rope around the connecting pipe to be adjusted. Adjust the rack so that the size of the circular loop is larger than the circumference of the air supply pipe steel ring. Insert the end steel rings of the two sections of the air cylinder into the ferrule, and turn the two knob screws clockwise to tighten the ferrule and clamp the end steel ring of the air supply pipe to complete the connection and tightening of the air supply pipe. When disassembling, turn the knob counterclockwise to remove the rack from the sleeve, so that the ferrule belt is separated from the air supply pipe and the air supply pipe is removed.

[0040] In addition, the ferrule can not only limit the position of the wire rope, but also seal the gap at the end connection of the air supply pipeline.

[0041] The number of steel wire ropes can be set to multiple and independent of each other, so as to adapt to the different diameter changes of the steel ring or flange of the air supply pipeline.

[0042] The circumference of the tightened wire rope is smaller than the circumference of the steel ring and flange at the end of the air supply pipe. No matter how the air volume and pressure in the pipe change, the steel ring or flange at the end of the soft air supply pipe will not fall off from the clamping sleeve.

[0043] A steel wire rope is used to replace the steel ring at one end of the soft air duct, and the soft air duct is used as a clamping sleeve to make a single-clamp clamp-belt soft air duct. By locking and unlocking the steel ring at the other end of the soft air duct, the soft air duct can be quickly disassembled and connected.
