Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric power pipe port expansion, in particular to a plastic electric power pipe port expansion structure. Background Art
[0002] Electric power pipes are usually used as cable protection pipes. This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, no pollution, not easy to age, light weight and easy construction.
[0003] In the existing technology, during the installation of power pipes, it is necessary to use expanding equipment to expand the ends of the power pipes. However, when the power pipes are installed outdoors, there are not many tools available. When simple tools are used to expand the pipes, the power pipes are prone to shrinkage after the expansion due to their greater toughness. In this case, personnel are required to operate again, and multiple operations are required to complete the operation, which greatly delays time and affects work efficiency. In addition, the power pipes are inconvenient to fix during expansion, and the single clamping tool is prone to slipping during expansion, affecting the quality of operation.
[0004] Therefore, a plastic power pipe port expansion structure is urgently needed to solve this problem. Utility Model Content
[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:
[0006] The technical solution adopted by the utility model to solve its technical problems is: a plastic electric power pipe port expansion structure, including a heating expansion ring, an expansion plate is installed at one end of the heating expansion ring, a plurality of interfaces are opened on the inner side of the expansion plate, an electric power pipe body is arranged on the outer side of the heating expansion ring, a hollow column is inserted in the middle of the heating expansion ring, a push head is slidably sleeved on the outer surface of the hollow column, a plurality of limit plates are annularly arranged on the outer surface of the push head, the limit plate is slidably matched with the interface, and a center rod is movably inserted in the inner side of the hollow column.
[0007] Preferably, a latch is movably inserted into one end of the outer surface of the hollow column, and a plurality of through openings for use with the latch are opened on the outer surface of the central rod.
[0008] Preferably, a top plate is fixedly mounted on one end of the central rod, and the outer surface of the top plate is rotatably connected to two linkage arms.
[0009] Preferably, a plurality of anti-slip sheets are provided on one end of the outer surface of the linkage arm, and the anti-slip sheets are in contact with the inner wall of the power pipe body.
[0010] Preferably, a ring sleeve is slidably provided on the outer surface of the hollow column, and the outer surface of the ring sleeve is rotatably connected to two swing plates, and the two swing plates are rotatably connected to each other.
[0011] Preferably, one end of the top plate is annularly connected to two positioning rods, and the other ends of the two positioning rods are inserted and slidably arranged with the ring sleeve.
[0012] Beneficial effects of the utility model:
[0013] (1) The utility model discloses a plastic electric pipe port expansion structure. A person puts the plastic electric pipe, that is, the port of the electric pipe body described in the figure, on a heating expansion ring, and then pulls the center rod to slide in the hollow column. The movement of the center rod drives the top plate to move, and the top plate drives the linkage arm to move. The swing plate flips and moves under the drive of the linkage arm. After the swing plate moves, it unfolds in the electric pipe body and contacts the inner wall of the electric pipe body. Then, the pin is inserted into the through hole on the center rod to fix the entire mechanism to maintain a stable state when the electric pipe body is expanded.
[0014] (2) The switch of the heating expansion ring is turned on by an external controller. After the heating expansion ring is turned on, it gradually heats up to a certain temperature and gradually melts the end of the power tube body that contacts the heating expansion ring. When it melts to a certain degree, the personnel pre-installs the push head on the outer surface of the hollow column. During operation, the push head is pushed to move by an external telescopic device. As the push head slides on the outer surface of the hollow column, it is driven to enter the inner side of the expansion piece and fit into the interface opened on the inner side of the expansion piece. As the push head continues to move in the direction of the heating expansion ring, the expansion piece is continuously pushed open, so that the hot-melt power tube body port is expanded as the expansion piece gradually unfolds, which is beneficial to the automatic matching structure softening of the port of the power tube and improves the port expansion quality.

A person puts the plastic power pipe, that is, the port of the power pipe body 2 described in the figure, on the heating expansion ring 1, and then pulls the center rod 11 to slide in the hollow column 7. The movement of the center rod 11 drives the top plate 12 to move, and the top plate 12 drives the linkage arm 9 to move after the movement. Under the drive of the linkage arm 9, the swing plate 14 flips and moves. After the swing plate 14 moves, it is unfolded in the power pipe body 2 and conflicts with the inner wall of the power pipe body 2, which is beneficial to limit it before the port expands to prevent sliding, and has high stability.
[0024] Example 2
[0025] On the basis of Example 1, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a latch 8 is movably provided at one end of the outer surface of the hollow column 7, a plurality of through holes for use with the latch 8 are provided on the outer surface of the center rod 11, a top plate 12 is fixedly sleeved at one end of the center rod 11, and two linkage arms 9 are rotatably connected to the outer surface of the top plate 12, and a plurality of anti-slip sheets 15 are provided at one end of the outer surface of the linkage arm 9, and the anti-slip sheets 15 are in conflict with the inner wall of the power tube body 2, and the latch 8 is inserted into the through hole on the center rod 11, so that the entire mechanism is fixed to maintain a stable state when the power tube body 2 is expanded, and then the switch of the heating expansion ring 1 is turned on from the external controller, and the heating expansion ring 1 is gradually heated to a certain temperature after being turned on. The end of the power pipe body 2 that contacts the heating expansion ring 1 gradually melts. When it melts to a certain degree, the personnel pre-installs the push head 5 on the outer surface of the hollow column 7. During operation, the push head 5 is pushed to move by an external telescopic device. As the push head 5 slides on the outer surface of the hollow column 7, the push head 5 is driven to enter the inner side of the expansion piece 4 and fits and contacts the interface 3 opened on the inner side of the expansion piece 4.

[0026] When the utility model is used, the specific working principle is as follows:
[0027] The plastic power tube, which is the port of the power tube body 2 described in the figure, is put on the heating expansion ring 1 by personnel, and then the center rod 11 is pulled to slide in the hollow column 7. The movement of the center rod 11 drives the top plate 12 to move, and the top plate 12 drives the linkage arm 9 to move. Under the drive of the linkage arm 9, the swing plate 14 flips and moves. After the swing plate 14 moves, it unfolds in the power tube body 2 and conflicts with the inner wall of the power tube body 2. Then, the pin 8 is inserted into the through hole on the center rod 11 to fix the entire mechanism to maintain a stable state when the power tube body 2 is expanded. Then, the switch of the heating expansion ring 1 is turned on from the external controller, and the heating expansion ring 1 is heated. After the ring 1 is opened, it gradually heats up to a certain temperature and gradually melts the end of the power tube body 2 that contacts the heating expansion ring 1. When it melts to a certain degree, the personnel pre-sets the push head 5 on the outer surface of the hollow column 7. During operation, the push head 5 is pushed to move by an external telescopic device. As the push head 5 slides on the outer surface of the hollow column 7, the push head 5 is driven to enter the inner side of the expansion piece 4 and fits and contacts the interface 3 opened on the inner side of the expansion piece 4. As the push head 5 continues to move in the direction of the heating expansion ring 1, the expansion piece 4 is continuously pushed away, so that the hot-melt port of the power tube body 2 is expanded as the expansion piece 4 gradually unfolds, thereby completing the entire process.
