Description

Technical Field

[0001] The utility model relates to the technical field of molecular pump groups, in particular to a molecular pump exhaust moving device. Background Art

[0002] A molecular pump is a vacuum pump that uses a high-speed rotating rotor to transfer momentum to gas molecules, enabling them to obtain a directional velocity, thereby being compressed and driven towards the exhaust port and then pumped away by the fore pump. A molecular pump exhaust platform, also known as a molecular pump group, is a system that achieves a vacuum environment by combining various pumps.

[0003] However, most existing molecular pump exhaust platforms are braked by the braking devices on the moving wheels when moving. After long-term use of the moving wheels, the internal braking devices will be damaged, resulting in the inability to achieve the braking effect. At the same time, the molecular pump exhaust platform is supported by the braking devices of the moving wheels, with poor stability. Therefore, those skilled in the art have provided a molecular pump exhaust moving device to solve the problems raised in the above background art. Summary of the Utility Model

[0012] Furthermore, chutes are provided inside the bottom plate and at the positions of the sliders, and the two sliders are respectively limited to slide inside the corresponding chutes;

[0013] Through the above technical solution, the movable sleeve is limited by the sliders and chutes, so that it can move on the lead screw.

[0014] Furthermore, the outer ends of the two sliders are respectively fixedly connected to the corresponding support plates;
