Description

Technical Field

[0001] The utility model relates to the technical field of HDPE double-wall corrugated pipes, in particular to a HDPE double-wall corrugated pipe structure. Background Art

[0002] In the use of HDPE double-wall corrugated pipes, two HDPE double-wall corrugated pipes need to be connected and fixed, but no sealing structure is set, which will directly lead to leakage of the fluid during the circulation process, and when the left and right pipes are connected, the pipe connection that is not subjected to internal support force is extremely prone to deformation and collapse.

[0003] The prior art patent CN216046109U discloses a HDPE double-wall corrugated pipe with a sealing structure. The pipe is spirally connected to the left pipe by means of a threaded sleeve, so that the left clamp ring and the right clamp ring are respectively installed in the inner part. When the left and right pipes are connected, the left clamp ring and the right clamp ring are just inside the connection of the entire pipe. Under the connection and cooperation of multiple groups of positioning brackets, a group of central brackets are used to provide corresponding internal supporting forces for the connection of the left and right pipes. As the left pipe is inserted into the double-wall expansion, the first sealing ring fits into the recess outside the left pipe. When the plastic sleeve is subjected to the artificial traction force and quickly realizes the spiral connection with the double-wall expansion under the auxiliary limiting action of the limit sleeve, the second sealing ring and the third sealing ring are fitted and attached. When the end faces are tightly attached, the two will cooperate with the first sealing ring to play a double sealing role for the insertion of the left pipe.

[0004] However, in the aforementioned prior art, when connecting two bellows, the operation is complicated, the fixation cannot be completed quickly, and the connection efficiency is low. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 is a sectional view of the whole of the first embodiment of the utility model, Figure 3 The utility model Figure 2 A magnified view of the local structure at A.

[0024] The utility model provides a HDPE double-wall corrugated pipe structure, comprising two double-wall corrugated pipes 101 and two connecting components, wherein the connecting components include a first mounting ring 102, a second mounting ring 103, a clamping block 104, a first magnet 105, a telescopic unit, a rod body 106, a second magnet 107, a fixing ring 108, a first spring 109 and a handle 114, wherein the first mounting ring 102 has a clamping groove 110 and a groove 111, the second mounting ring 103 has a groove body 112, the clamping block 104 has a through hole 113, and the telescopic unit includes a telescopic rod 115 and a second spring 116.

[0025] According to this specific embodiment, the two double-walled corrugated tubes 101 are aligned and then the block 104 is moved, the inclined surface of the block 104 contacts the first mounting ring 102, and then the block 104 is driven to move downward, thereby entering the slot 110. At this time, the first magnet 105 and the second magnet 107 attract each other, and the second magnet 107 moves downward into the through hole 113. At the same time, the rod body 106 moves downward, driving the fixing ring 108 to move downward, so that the first spring 109 is stretched, and the block 104 is limited, so that the two double-walled corrugated tubes 101 are connected.

[0026] The first mounting ring 102 and the second mounting ring 103 are both fixedly connected to the double-walled corrugated tube 101 and symmetrically distributed at both ends of the double-walled corrugated tube 101. The first mounting ring 102 has a slot 110 and a groove 111. The second mounting ring 103 has a slot body 112. The telescopic unit is arranged inside the slot 110. The block 104 is arranged on the telescopic unit. The block 104 has a through hole 113. The first magnet 105 is fixedly connected to the block 104 and is located at the through hole 113. The inner wall, one end of the rod body 106 passes through the groove 111 and is located inside the slot 110, one end of the rod body 106 is fixedly connected to the second magnet 107, the first magnet 105 and the second magnet 107 attract each other, the fixing ring 108 is fixedly connected to the rod body 106 and is sleeved on the outer wall of the rod body 106, the two ends of the first spring 109 are respectively movably connected to the inner top wall of the groove 111 and one side of the fixing ring 108, and the first spring 109 is sleeved on the outer wall of the rod body 106. By aligning the two double-walled corrugated tubes 101 and then moving the block 104, the inclined surface of the block 104 contacts the first mounting ring 102, and then the block 104 is driven to move downward, thereby entering the slot 110. At this time, the first magnet 105 and the second magnet 107 attract each other, and the second magnet 107 moves downward into the through hole 113. At the same time, the rod body 106 moves downward, driving the fixing ring 108 to move downward, so that the first spring 109 is stretched, and the block 104 is limited, so that the two double-walled corrugated tubes 101 are connected, thereby allowing for quick fixation and improving connection efficiency.

[0027] Secondly, the handle 114 is fixedly connected to the rod body 106 and is located at the other end of the rod body 106. The handle 114 can be used to pull the rod body 106 upward, thereby driving the second magnet 107 to move upward and disengage from the through hole 113, thereby removing the block 104 and separating the two double-wall corrugated tubes 101.

After the block 104 is separated from the slot 110, the second spring 116 contracts, and the telescopic rod 115 contracts accordingly, thereby improving stability and causing the block 104 to move upward.

[0029] When the utility model is used to connect the double-walled corrugated tubes 101, the two double-walled corrugated tubes 101 are aligned, and then the block 104 is moved, and the inclined surface of the block 104 contacts the first mounting ring 102, and then the block 104 is driven to move downward, thereby entering the slot 110, and at this time the first magnet 105 and the second magnet 107 attract each other, and the second magnet 107 moves downward into the through hole 113, and at the same time the rod body 106 moves downward, driving the fixing ring 108 to move downward, so that the first spring 109 is stretched, and the block 104 is limited, so that the two double-walled corrugated tubes 101 are connected. Through the above-mentioned structural setting, quick fixation can be performed to improve the connection efficiency.
