The main body mechanism includes a central sealing piston column, a connecting end, a support plate, an internal tube, a connecting strip, an internal tube, a transition tube and a lower connecting end. The connecting end is fixedly installed on the upper end of the central sealing piston column. Through the improvement and installation of the main body mechanism, the flexible silicone member is made of methylphenyl vinyl silicone rubber (phenyl silicone rubber for short) and flame retardant as the basic material. As the deformation functional structural body of the plugger, it should have the properties of high and low temperature resistance, corrosion resistance, fire resistance, high energy radiation resistance, heat insulation and the like.

[0004] When the device is in use, a central sealing piston column arranged in a silicone rubber sealing ring is limited and fixed from both ends through a connecting ring 1 and a fixing ring, so that the central sealing piston column can be stably installed in the silicone rubber sealing ring. However, when the connecting ring 1 and the fixing ring 1 are limited and fixed, the limiting setting of the connecting ring 1 and the fixing ring 1 is achieved by screwing together a plurality of connecting bolts 1 and fixing screw holes 2. When the device is fixedly installed or disassembled for maintenance, tools are required, and the plurality of connecting bolts 1 need to be turned and screwed multiple times, which makes installation and disassembly inconvenient. Utility Model Content

When the device is fixedly installed or disassembled for maintenance, tools are needed, and the plurality of connecting bolts 1 need to be rotated and screwed together multiple times, which causes inconvenience during installation and disassembly.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-temperature resistant and high-strength cable pipe plugger, comprising a central sealing piston column, a connecting sealing tube is arranged on the outside of the central sealing piston column, and a connecting seat is connected to both ends of the connecting sealing tube, and a plurality of card grooves are opened on the surface of the connecting seat, and a connecting ring is arranged in each of the two connecting seats, and a plurality of card blocks that are engaged with the card grooves are arranged at equal distances on the side walls of the connecting rings, and an annular stopper that is pressed against the connecting ring is arranged in the two connecting seats and between the two connecting rings, and a group of springs are connected between the surfaces of the two annular stoppers and the two ends of the connecting seats.

[0007] As a preferred technical solution of the utility model, the surface of the annular stopper and the surface that abuts against and fits against the surface of the connecting ring are both connected with rubber gaskets.

[0008] As a preferred technical solution of the present utility model, the card slot is L-shaped as a whole.

[0009] As a preferred technical solution of the utility model, a plurality of springs are arranged in each group of springs, and the plurality of springs are arranged and distributed in a circular shape.

[0010] As a preferred technical solution of the utility model, a connecting end is provided at one end of the central sealing piston column, a transition tube is provided at the other end of the central sealing piston column, and a lower connecting end is provided at one end of the transition tube away from the connecting end.

[0011] As a preferred technical solution of the utility model, an internal tube is arranged in the connecting end, a plurality of support plates are arranged between the connecting end and the internal tube, a connecting strip is arranged in the internal tube, and an internal tube is arranged in the internal tube and below the connecting strip.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] The locking block is connected with the card slot and the card block to realize the limiting connection between the connecting ring and the connecting seat. The two connecting rings connected by the limiting connection limit the two ends of the central sealing piston column arranged in the connecting sealing tube. At the same time, the spring and the annular block are matched to make the elastic force generated by the spring act on the annular block, so that the annular block squeezes the connecting ring, and then the card block arranged on the side wall of the connecting ring can be tightly engaged in the card slot, further improving the stability of the connection of the central sealing piston column in the connecting sealing tube. When in use, this structure only needs to be pressed and rotated to complete the limiting of the two connecting rings on the two ends of the central sealing piston column, making the installation and disassembly of the central sealing piston column more convenient, thereby improving the practicality of the device.
