[0002] In industrial production and laboratory applications, oil-free vertical vacuum pumps are widely used due to their high efficiency and environmental protection. However, during transportation, installation, and use, oil-free vertical vacuum pumps may be affected by various external factors such as vibration and impact. These factors can cause pump body damage, performance degradation, or shortened service life. Therefore, when transporting oil-free vertical vacuum pumps, protective devices are needed to protect them.

[0003] In the prior art, most oil-free vertical vacuum pump protection devices use simple fixing methods such as bolt fixing or buckle fixing. These methods can prevent pump body movement to some extent, but they often cannot provide sufficient protection when facing strong vibration or impact. These protection devices are cumbersome to operate and inefficient when adjusting and fixing oil-free vertical vacuum pumps, and they are difficult to adapt to different sizes and models of pump bodies. Therefore, we propose a safety protection device for oil-free vertical vacuum pumps. SUMMARY

An installation shell is arranged on the front side outer wall of the right mounting block, and an installation shaft is rotatably arranged in the installation shell. A first bevel gear is connected to the installation shaft through a key. The bidirectional screw penetrates the installation shell side wall and extends into the installation shell. A second bevel gear is connected to the bidirectional screw through a key inside the installation shell. The second bevel gear is meshed with the first bevel gear. A worm wheel is connected to the installation shaft through a key. A worm is rotatably arranged on the installation shell and is meshed with the worm wheel.

[0007] As a further scheme of the utility model: the base is internally provided with a cavity, a placing plate is slidably arranged in the cavity, and a plurality of damping rods are also evenly arranged in the base.

[0009] As a further scheme of the utility model: the damping rod, the damping spring and the damping pad form a damping structure.

[0010] As a further scheme of the utility model: the outer end of the worm is provided with a handle.

[0011] Compared with the prior art, the utility model has the beneficial effects as follows:

[0012] 1. The worm is rotated to drive the worm wheel and the mounting shaft to rotate, and then the bevel gear transmission is used to rotate the bidirectional screw rod, so that the front and rear limiting plates are driven to slide on the slide rod, the clamping and fixing of the oil-free vertical vacuum pump of different sizes are realized, the operation is simple, different models of pump bodies can be flexibly adapted, the universality and practicality of the device are improved, and in addition, under the action of the worm wheel and worm self-locking function, the fixing quality of the limiting plate for the pump body is ensured.
