Description

Technical Field

[0001] The utility model relates to the field of water pipes, in particular to a plug structure for cooling water pipes. Background Art

[0002] After searching Chinese patents, the publication number is: CN212718658U, a water pipe plugging head, including a cover body, a first telescopic rod and a sealing plug, the bottom end of the cover body is fixed with a second telescopic rod, the bottom end of the mounting plate is provided with a threaded rod, and a fixed plate is fixed on one side of the threaded rod, the top of the cover body is provided with a sealing plug, and the interior of the cover body is provided with a reinforcing structure. The utility model is provided with a fixed plate on one side of the mounting plate, and the fixed plate and the mounting plate are connected by a threaded rod and a connecting rod. The threaded rod and the mounting plate form a threaded connection, and twisting the threaded rod can drive the fixed plate on one side to move. After the plugging head is stuck into the water pipe, twisting the threaded rod can allow the fixed block to clamp the water pipe in the middle, so that the device can be stably fixed on the water pipe, the connecting rod can be telescopic, and the connecting rod can prevent the fixed plate from being offset, thereby achieving the purpose of the water pipe plugging head being stably fixed on the water pipe.

[0003] The existing plugging structure is not easy to install and disassemble. Generally, the plugging structure fixes the water pipe and the plug by multiple screws. When disassembling and assembling, tools are needed to disassemble and assemble it. The disassembly and assembly process requires the installation and disassembly of multiple bolts separately. The operation is very cumbersome and troublesome, which increases the workload and reduces the work efficiency. The plugging head cannot be replaced. Generally, the size of the plugging head is fixed and can only be used for water pipes of specific diameters. When it is necessary to plug water pipes of different diameters, the entire plugging device needs to be replaced, which increases the use cost and reduces the practicality and applicability. In order to solve the above-mentioned problems, we propose a plugging structure for cooling water pipes. Utility Model Content
