The free-hanging clamping and inflating device is used, and with the universal wheel base, the clamp can be conveniently and flexibly adjusted to any position and angle in the space, ensuring that the aluminum-plastic with high hardness The tube end fits easily into the collet without requiring the operator to struggle with the tubing to adjust the tube end position.

Description

A device for detecting the airtightness of aluminum-plastic pipes

technical field

The utility model relates to a device for detecting the airtightness of an aluminum-plastic pipe.

Background technique

At present, in the air tightness testing and clamping of aluminum-plastic pipes, the two ports of the pipe to be tested are enlarged manually with a special flarer, and then the two ports are respectively plugged with self-made inflatable nozzles and plugs. Then, pressurized gas is filled into the pipe to be tested for air tightness testing. However, because the pipe material is relatively hard, manual flaring with a flarer is labor-intensive, and the operator will often be exhausted and physically exhausted for continuous detection of several pipes, which seriously affects the efficiency. Due to the smooth surface processing of the plug head, as the pressure of the gas inflated continues to increase, air leakage may occur, or even reversely flush the plug head, resulting in detection failure, and in severe cases, safety accidents may occur.

Contents of the invention

The purpose of the invention of the utility model is to overcome the defects of the prior art and provide a convenient airtightness detection device for aluminum-plastic pipes.

In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical scheme, an aluminum-plastic pipe airtightness detection device, which includes a gear mouth fixture arranged on the bracket and connected to the clamping cylinder, Inflation nozzle and solid plug, start the clamping cylinder switch, clamp the aluminum-plastic pipe to be tested with the gear mouth clamp, block one end of the aluminum-plastic pipe with a solid plug, insert one end of the aluminum-plastic pipe with the inflation nozzle, and start inflation The cylinder switch can realize the detection.

The tooth mouth fixture and the clamping cylinder are suspended on the bracket through the suspension frame and can be rotated 360°, the position of the aluminum-plastic pipe can be changed arbitrarily, and the detection is more convenient.

Universal wheels are arranged at the bottom of the support to facilitate the movement of the support.

The upper and lower teeth of the tooth mouth clamp are semicircular, which is firm and reliable, and at the same time effectively reduces the compression deformation of the pipe.

The beneficial effects of the utility model are: adopting the free suspension clamping and inflating device, combined with the universal wheel base, the clamp can be conveniently and flexibly adjusted to any position and angle in the space, ensuring that the port of the aluminum-plastic pipe with high hardness can be easily fixed. Places in the collet without the operator having to fiddle with the tubing to adjust the tube end position.
