DETAILED DESCRIPTION

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a pipeline quick-disconnect telescopic sealing connection joint, comprising:

[0027] Several slide bars 1, preferably four, are arranged in parallel in a square orientation;

[0028] The left connecting plate 2 is provided with a flow hole 21 inside thereof, and is provided with a plurality of sliding holes 22 to form a sliding connection with one end of the plurality of sliding rods 1 (and the one end of the plurality of sliding rods 1 is not allowed to be separated), and the left connecting plate 2 can form a sealed connection with the left pipe A by means of a flange structure;

[0029] The right connecting plate 3 is provided with a flow hole 21 inside thereof, and is provided with a plurality of sliding holes 22 to form a sliding connection with the other ends of the plurality of sliding rods 1 (and can allow the other ends of the plurality of sliding rods 1 to be detached), and the right connecting plate 3 can form a sealed connection with the right pipe B by means of a flange structure;

[0030] The movable plate 4 has a connecting hole (not shown) inside thereof and is fixedly connected to the plurality of slide bars 1;

[0031] A telescopic tube 5, one end of which is a fixed end and the other end is a movable end, the fixed end is fixed to the left connecting plate 2 and is sealedly connected to the flow hole 21 of the left connecting plate 2, and the movable end is fixed to the movable plate 4 and is sealedly connected to the communication hole of the movable plate 4;

[0032] An outer rubber sealing ring 6 is fixed to the side of the movable plate 4 facing the right connecting plate 3, and an inner rubber sealing ring 7 is fixed to the side of the right connecting plate 3 facing the movable plate 4. Figure 4 As shown, the inner diameter of the outer rubber sealing ring 6 is equal to the outer diameter of the inner rubber sealing ring 7 (a gap is drawn for easy identification), and the inner diameter of the inner rubber sealing ring 7 is preferably equal to the diameter of the flow holes 21 of all the right connecting plates 3; moreover, the thickness of the inner rubber sealing ring 7 is greater than the thickness of the outer rubber sealing ring 6, and when the inner rubber sealing ring 7 is axially squeezed, radial expansion occurs, so that the inner circumferential surface of the outer rubber sealing ring 6 and the outer circumferential surface of the inner rubber sealing ring 7 are radially squeezed, thereby improving the sealing effect;

[0033] At least two pairs of quick-release buckles are provided between the corresponding positions of the movable plate 4 and the right connecting plate 3. Specifically, two pairs of quick-release buckles (symmetrically installed) are provided, and each pair of quick-release buckles includes a hook body 8 and a handle 9. The two hook bodies 8 are fixed on both sides of the movable plate 4, and the two handles 9 are installed on both sides of the right connecting plate 3. The hook bodies 8 and the handles 9 are both made of stainless steel. When the handles 9 are turned to the position tightly fastened with the hook bodies 8, the movable plate 4 and the right connecting plate 3 are compressed and connected by means of the outer rubber sealing ring 6 and the inner rubber sealing ring 7, and the compression strength is preferably greater than 4000Pa.

[0034] Among them, the telescopic tube 5 has a steel wire keel, which does not deform under a negative pressure of 3000Pa. The cloth covering the outer surface of the steel wire keel is made of non-woven fabric or PVC cloth, which can be flexibly selected according to the properties of the gas; in this embodiment, the telescopic adjustment distance of the telescopic tube 5 is between 200mm-400mm.

[0035] When using the utility model to connect pipelines:

[0036] like Figure 5 As shown, the left connecting plate 2 is sealedly connected to the left pipe A through a flange, and the flow hole 21 of the left connecting plate 2 is connected to the left pipe A; the right connecting plate 3 is sealedly connected to the right pipe B through a flange, and the flow hole 21 of the right connecting plate 3 is connected to the right pipe B;

[0037] The movable plate 4 slides with the sliding rod 1 in the sliding holes 22 of the left connecting plate 2 and the right connecting plate 3, and moves closer to the right connecting plate 3 until they are connected, and then the quick-release buckle is locked to press and connect the movable plate 4 and the right connecting plate 3; at this time, since the thickness of the inner rubber sealing ring 7 is greater than the thickness of the outer rubber sealing ring 6, when the inner rubber sealing ring 7 is axially squeezed, radial expansion will occur, so that the inner circumferential surface of the outer rubber sealing ring 6 and the outer circumferential surface of the inner rubber sealing ring 7 are radially squeezed, thereby improving the sealing effect; and, the movable end of the telescopic tube 5 is connected with the right side pipeline B as the movable plate 4 moves (the telescopic tube 5 is stretched), that is, the left side pipeline A is sealed and connected with the right side pipeline B through the left connecting plate 2, the telescopic tube 5, and the right connecting plate 3 in sequence.

[0038] When the utility model needs to be disassembled for maintenance:

[0039] Unlock the quick-release buckle to release the pressing connection between the moving plate 4 and the right connecting plate 3;

[0040] like Figure 6 As shown, the movable plate 4 moves toward the left connecting plate 2, driving the movable end of the telescopic tube 5 to be out of contact with the right pipe B (the telescopic tube 5 is compressed), until the sliding rod 1 moving with the movable plate 4 is disconnected from the sliding hole 22 of the right connecting plate 3. At this time, the sliding rod 1 slides in the sliding hole 22 of the left connecting plate 2 and does not disconnect;

[0041] Since the right connecting plate 3 is disconnected from the sliding rod 1, that is, the left pipeline A and the right pipeline B are disconnected, maintenance work can be carried out conveniently.

[0042] After the maintenance is completed, each slide rod 1 can be inserted into the corresponding slide hole 22 of the right connecting plate 3, and the above-mentioned operation steps of "using the utility model to connect pipelines" are repeated.

[0043] In short, by using the utility model, the disassembly and assembly of the pipeline connection position can be completed easily and quickly, which has the advantages of saving time and labor.
