[0001] This utility model relates to the field of vacuum pump protection technology, specifically a protective housing for a vacuum pump. Background Technology

[0002] In industrial production and laboratory environments, vacuum pumps are key equipment that are widely used and often require protective housings to ensure safe operation, reduce external impact, and facilitate movement.

[0003] Traditional vacuum pump protective structures often lack effective moving mechanisms in their outer casings, requiring external tools or multiple people to handle them, resulting in low efficiency. Furthermore, the fixed protective frame ensures that the vacuum pump is always installed at the same height, making it unsuitable for different usage scenarios. The protective structures are mostly enclosed designs, requiring complete disassembly for maintenance or parts replacement, which is cumbersome and time-consuming. Therefore, new technical solutions are needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a protective housing for a vacuum pump, in order to solve the problems mentioned in the background art. In use, most of the existing protective housings for vacuum pumps lack an effective moving mechanism, requiring external tools or multiple people to work together during transportation, which is inefficient. Furthermore, the fixed protective frame causes the installation height of the vacuum pump to always be the same, which cannot meet different usage occasions. The protective structure is mostly a closed design, which requires the whole body to be disassembled when inspecting or replacing parts, which is cumbersome and time-consuming.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective shell for a vacuum pump, comprising a vacuum pump body, a fixing plate installed at the lower end of the vacuum pump body, and a supporting protective structure connected to the outside of the fixing plate, the supporting protective structure comprising four guide rods, four fixing seats, two mounting shafts, two protective frames, and a movable plate;

[0006] The four guide rods are respectively movably embedded at the four corners of the fixed plate, the four fixed seats are respectively installed at the bottom ends of the four guide rods, the two ends of the two mounting shafts are respectively connected to the side walls of the four fixed seats, the bottom ends of the two protective frames are respectively movably fitted onto the upper ends of the two mounting shafts, and the movable plate is fixedly installed at the lower ends of the four fixed seats.

[0007] As a preferred protective housing for a vacuum pump according to this utility model, four snap-fit ​​components are installed between the two protective frames and the four guide rods;

[0008] Each of the four snap-fit ​​components includes: a fixing block, a snap-fit ​​block, and an insert rod;

[0009] The fixing block is fixedly installed on one side of the upper end of the guide rod, the snap-fit ​​block is fixedly installed on the upper end of the protective frame, and one end of the insert rod is movably embedded in the snap-fit ​​block and the fixing block.

[0010] As a preferred protective housing for a vacuum pump according to this utility model, four support columns are installed between the movable plate and the fixed plate.

[0011] As a preferred protective housing for a vacuum pump according to this utility model, four casters are installed at the four corners of the lower end of the movable plate.

[0012] As a preferred protective housing for a vacuum pump according to this utility model, a limiting plate is installed at the top of the guide rod.

[0013] As a preferred protective housing for a vacuum pump according to this utility model, two lifting handles are installed on both sides of the fixing plate.

[0014] As a preferred protective housing for a vacuum pump according to this utility model, the protective frame is an L-shaped protective frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the protective shell of the vacuum pump has a reasonable structural design;

[0016] The equipment can be easily moved by four casters at the bottom of the movable plate, greatly improving portability. The guide rod and fixed base are linked and combined with the support column to form a multi-level buffer, effectively absorbing operating vibration and preventing pump displacement. The overall height of the fixed plate above the guide rod can be adjusted, allowing the vacuum pump body to be moved to the top of the protective frame, changing the operating height of the vacuum pump to suit different working scenarios. The L-shaped protective frame is hinged to the fixed base by the mounting shaft and can be rotated outward to fully expose the pump body maintenance surface for quick maintenance. The snap-fit ​​component allows for quick locking and unlocking of the protective frame and guide rod, balancing ease of operation and structural stability. The support column is located between the movable plate and the fixed plate, further dispersing load pressure, suppressing resonance transmission, and extending pump life.

[0024] In this technical solution, a protective shell for a vacuum pump includes a vacuum pump body 1, a fixing plate 2 installed at the lower end of the vacuum pump body 1, and a supporting protective structure connected to the outside of the fixing plate 2. The supporting protective structure includes four guide rods 3, four fixing seats 4, two mounting shafts 5, two protective frames 6, and a movable plate 7.

[0025] Four guide rods 3 are movably embedded in the four corners of the fixed plate 2, four fixed seats 4 are respectively installed at the bottom of the four guide rods 3, the two ends of the two mounting shafts 5 are respectively connected to the side walls of the four fixed seats 4, the bottom ends of the two protective frames 6 are respectively movably fitted onto the upper ends of the two mounting shafts 5, and the movable plate 7 is fixedly installed at the lower end of the four fixed seats 4.

[0026] In this technical solution, when installing the vacuum pump body 1 for protection, the operator first fixes the vacuum pump body 1 to the upper end of the fixing plate 2 with bolts. Then, the protective frames 6 at the upper ends of the two mounting shafts 5 are moved so that the two protective frames 6 are located on both sides of the vacuum pump body 1. Finally, the clamping components limit and fix them. The vacuum pump body 1 is protected by the two protective frames 6. In use, the gas pipe and power supply can be connected through the gaps of the two protective frames 6 and the two sides. The movable plate 7 can be used to move the vacuum pump body 1. For different applications, the two protective frames 6 can be flipped to the outside. Then, the fixing plate 2 is moved to the top of the four guide rods 3. Finally, the two protective frames 6 are reset. The top of the two protective frames 6 supports the fixing plate 2, so that the vacuum pump body 1 is located on the upper end of the protective frames 6, thus changing the installation height of the vacuum pump body 1.

[0031] In some technical solutions, reference Figure 1 Four support columns 11 are installed between the movable plate 7 and the fixed plate 2 to effectively absorb operating vibrations and prevent pump displacement. Four casters 12 are installed at the four corners of the lower end of the movable plate 7, enabling easy transport of the equipment and significantly improving portability. A limit plate 13 is installed at the top of the guide rod 3 to prevent the movable plate 7 from detaching from the guide rod 3, ensuring safe and controllable lifting. Two lifting handles 14 are installed on both sides of the fixed plate 2 for easy manual handling or precise positioning, reducing labor intensity. The protective frame 6 is an L-shaped protective frame 6, providing protection for the sides and top of the vacuum pump.
