[0002] Gas meters are widely used in daily life and manufacturing industries to accumulate natural gas usage. Their installation environments are different, requiring anti-corrosion treatment on the surface of the meter case. The most common treatment is plastic spraying. In this process, the meter case needs to be cleaned first, and then the paint is sprayed onto the surface of the workpiece under the action of an electric field to form a powdery coating, which is then subjected to high-temperature baking and other treatments to form a protective coating.

[0003] During the processing, special hangers are required to hang the meter cases and transfer them to different workstations through conveyor lines. In the prior art, such as the patent number "201920500655.3", named "A processing line for a gas meter case", and the patent number "201920477218.4", named "A hook for spraying plastic on the upper shell of a gas meter case", the applicant found in the research that in the actual production process, the hangers used still have poor stability and large shaking amplitude, especially when placing meter cases in batches, the shaking is even greater, which can easily cause the resonance shaking of the meter cases on the hangers and lead to decoupling, which is completely unsuitable for the automated operation of the robotic arm, seriously affecting production efficiency.

[0012] As a preferred embodiment, a linear bearing is provided between the guide rod and the guide seat. By adopting the above scheme, the stability and smoothness of the sliding of the guide rod can be improved.

[0013] As a preferred embodiment, the base and the guide seat are both in a "T" shape, the base includes a connecting plate and a guide bottom plate, the guide seat includes a slide plate and a mounting plate, wherein the connecting plate and the mounting plate are arranged in parallel, and the guide bottom plate has a guide rail that slides with the slide plate. The above scheme is adopted to facilitate processing and quick installation, improve disassembly and assembly efficiency, etc.

[0014] As a preferred embodiment, the connecting plate has symmetrically arranged strip holes on the upper and lower sides of the guide bottom plate. The above solution is adopted to facilitate the adjustment of the overall installation height to adapt to the position of the hanger.
