5. The snap-fit latch-press connection structure of claim 4, wherein said anti-rotation stop cooperates with and limits one of said four insertable blocks adjacent to said securing sleeve.
6. A method for controlling the snap-together press-fit connection structure of claim 5, comprising the steps of:
step S1: before connection, firstly, the end part of the three-way connector is sequentially inserted into the space between the stop ring and the limiting ring, the pipeline drives a plurality of insertion fixture blocks to be respectively inserted into the space between the limiting ring and the stop ring through the inside of the insertion slots, the inclined end surfaces of the semicircular lug and the wedge block are mutually matched by rotating the pipeline by a certain angle clockwise, the insertion fixture blocks are circumferentially staggered with the insertion slots, the stop ring shields and limits the insertion fixture blocks, part of the insertion fixture blocks are staggered with the anti-rotation stop blocks, the insertion fixture blocks close to the direction of the fixed sleeve are contacted with and shielded and limited by the limiting shaft, the pipeline moves forwards axially, and the pipeline drives the sealing elastic rubber ring to be tightly contacted with the end part of the three-way connector through the circular plate, so that preliminary sealing connection is realized;
step S2, the rotating member is rotated forward to drive the rotating shaft to rotate, the rotating shaft drives the buckling block to be completely screwed into the rectangular hole, the rotating shaft torsionally compresses the torsion spring, then the rotating member is pressed downward, the rotating member drives the connecting rod to move towards the direction close to the pipeline through the rotating shaft, the connecting rod drives the anti-rotation stop block to slide out towards the direction close to the pipeline, simultaneously, after the rotating shaft drives the buckling block to move into the fixed sleeve, the rotating force of the rotating member is released, the torsion spring in the torsional compression state is reset to rotate and drives the rotating shaft to rotate, the rotating shaft drives the buckling block to rotate to the outside of the connecting rod, the buckling block is shielded and limited by the top plate of the fixed sleeve to limit the upward movement and the connecting rod can not move back outwards, the anti-rotation stop block can not move back towards the direction far away from the pipeline, at the moment, the anti-rotation stop block moves downwards and is positioned at the front of an inserting clamping block 3 close to the direction of the fixed sleeve, the shielding limit of the rotary table is reached, so that the rotary table cannot rotate anticlockwise; meanwhile, the limiting shaft is positioned in the clockwise rotation direction of one inserting fixture block close to the fixed sleeve, the maximum rotation angle position of the inserting fixture block is limited along the direction of the pointer, the pipeline is completely shielded and limited, the rotation phenomenon caused by mistaken collision in the pipeline connection process is prevented, the pipeline is conveniently and quickly sealed and buckled, the pipeline is conveniently limited and prevented from rotating after being buckled, and the automatic unlocking and separation caused by the rotation of the pipeline are prevented;
step S3: when the limitation needs to be removed, the rotating piece is rotated forward again to enable the buckling block to be rotated into the rectangular hole again, then the rotating piece is pulled outwards to enable the rotating piece to sequentially drive the anti-rotation stop block to be staggered with the inserting clamping block in the direction away from the pipeline through the rotating shaft and the connecting rod, the pipeline can be rotated to enable the pipeline to drive the inserting clamping block to be aligned with the inserting groove, and then the pipeline can be pulled out;
step S4: when the pipeline is installed and positioned correctly, the front end of the pipeline is connected with the three-way connector in a clamping and pressing mode by using a tool, and then the plug is connected with the top of the through hole channel above the fixed sleeve in a threaded mode so as to ensure the integrity of the whole structure.
