At this time, since the connecting tube 100 is deeply inserted into the matching tube 300, The abutment column 301d will just fit into the limiting groove 102 to form a preliminary lock. When the connecting tube 100 continues to go deeper, the first elastic pile 101a-2 and the second elastic pile 101a-3 will first shrink when encountering the through hole 301a. After the first elastic pile 101a-2 and the second elastic pile 101a-3 respectively enter the interior of the functional box 301, they will rebound respectively, and then they will each hit the abutment column 301d. Since the first elastic pile 101a-2 and the second elastic pile 101a-3 have different lengths, the abutment column 301d will move down to different heights.

The above sealing action can select the sealing level according to the actual situation.

Preferably, the auxiliary member 103 includes a first abutting ring 103a, which is fixedly connected to the inside of the connecting tube 100 through a fourth spring 103b, and the auxiliary member 103 also includes a first sealing ring 103c that abuts and cooperates with the first abutting ring 103a, and the first sealing ring 103c is fixedly connected to the connecting tube 100 through a fifth spring 103d.

There is a second wedge pile 103c-1. When the fixed column 101a moves toward the matching tube 300, the one-way tooth plate 101b-2 will first be pushed and contracted by the limiting tooth 301b it encounters. After passing through the limiting tooth 301b, the third spring 101b-1 rebounds, so that the one-way tooth plate 101b-2 engages with the limiting tooth 301b, and then is fixed again. Each movement of the fixed column 101a can correspond to each engagement, and can also correspond to the action inside the functional box 301.

The position of the guide hole 402b-1 is located below the guide pipe 403 on the horizontal plane.

Preferably, the special-shaped arm 502 includes a matching column 502a that fits with the limiting tooth 301b, a lifting column 502b fixedly connected to the matching column 502a, and a telescopic rod 502c fixedly connected to the fixing pile 501, the lifting column 502b is abutted and matched with the reset pile 301d-3, and the other end of the telescopic rod 502c is provided with a handle 502d fixedly connected to the matching column 502a. When unlocking is required, the staff grasps the handles 502d on both sides and moves them toward the middle part. At this time, the matching column 502a will hit the limiting tooth 301b, and will bring the limiting teeth on both sides. The position tooth 301b moves toward the center of the function box 301, so that the limit tooth 301b is disengaged from the latch tooth 101b, realizing the first step of unlocking. When operating the handle 502d, the lifting column 502b will contact the reset pile 301d-3, so that the abutment column 301d is lifted up. Since the limit tooth 301b is disengaged from the latch tooth 101b at this time, the connecting tube 100 will be disengaged from the matching tube 300, thereby completing the unlocking. Along with the disengagement of the connecting tube 100, the force acting on the first sealing ring 103c and the second sealing ring 302b is released, thereby restoring the original state.

When in use, the staff first aligns the fixing column 101a on the connecting tube 100 with the through hole 301a and inserts it. During the insertion process, the fixing column 101a will first abut against the abutting column 301d inside the function box 301. At this time, the sixth spring 301c will be compressed, and the abutting column 301d will move downward. At this time, since the connecting tube 100 is deeply inserted into the matching tube 300, the abutting column 301d will just fit into the limiting groove 102 to form a preliminary lock. When the connecting pipe 100 continues to go deeper, the first elastic pile 101a-2 and the second elastic pile 101a-3 will first shrink when encountering the through hole 301a. After the first elastic pile 101a-2 and the second elastic pile 101a-3 enter the inside of the function box 301, they will rebound respectively and then respectively hit the abutment column 301d. Since the lengths of the first elastic pile 101a-2 and the second elastic pile 101a-3 are different, the abutment column 301d will move down to different heights.

When the abutment column 301d is continuously pressed downward, the third wedge-shaped pile 301d-1 will firstly abut against the first abutment ring 103a on one side, so that the first abutment ring 103a moves toward the first sealing ring 103c, and because the first abutment ring 103a abuts and cooperates with the first sealing ring 103c, the first sealing ring 103c will have a force acting toward the top of the outer wall of the pipe, that is, it is squeezed toward the direction of the second sealing ring 302b to achieve preliminary sealing, and when the abutment column 301d is continuously pressed downward, the abutment column 301d is downward. The fourth wedge-shaped pile 301d-2 will abut against the second abutting ring 302a, so that the second abutting ring 302a moves toward the second sealing ring 302b, so that the second sealing ring 302b is pressed toward the first sealing ring 103c. At this time, since the abutting column 301d continues to press downward, the first sealing ring 103c is still pressed toward the second sealing ring 302b, and then the two sides are squeezed against each other, thereby achieving sealing. The above sealing action can select the sealing level according to the actual situation;

When the fixed column 101a moves toward the matching tube 300, the one-way tooth plate 101b-2 will first be pressed against the limit tooth 301b encountered and will shrink. After passing through the limit tooth 301b, the third spring 101b-1 rebounds, so that the one-way tooth plate 101b-2 is meshed with the limit tooth 301b, and then fixed again. Each movement of the fixed column 101a can correspond to each meshing, and can also correspond to the action inside the functional box 301.

When unlocking is required, the staff grabs the handles 502d on both sides and moves them toward the middle part. At this time, the matching column 502a will hit the limiting tooth 301b and move the limiting teeth 301b on both sides toward the center of the function box 301, so that the limiting tooth 301b is disengaged from the latch tooth 101b, thereby realizing the first step of unlocking. When operating the handle 502d, the lifting column 502b will contact the reset pile 301d-3, so that the abutting column 301d is brought up. Since the limiting tooth 301b is disengaged from the latch tooth 101b at this time, the connecting tube 100 will be disengaged from the matching tube 300, thereby completing the unlocking. Along with the disengagement of the connecting tube 100, the force acting on the first sealing ring 103c and the second sealing ring 302b is released, thereby restoring the original state.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
