By providing the protective net 102, the protective net 102 can isolate dust and other debris in the outside air when the air compressor is working, thereby preventing dust and other debris from accumulating inside the air compressor and causing damage to the air compressor. At the same time, the protective net 102 can be disassembled, cleaned, and replaced. The protective net 102 is formed by the rotating shaft 103, the first latch 105, and the mounting frame 101. Rotating structure, and the first latch 105 and the rotating shaft 103 form an elastic structure through the first spring 104, the protective net 102 forms a detachable structure through the first latch 105, the second latch 108 and the mounting frame 101, and the second latch 108 and the fixing seat 106 form an elastic structure through the second spring 107; the protective net 102 can isolate dust and other debris in the outside air when the air compressor is working, thereby preventing dust and other debris from accumulating inside the air compressor and causing damage thereto, and at the same time, the protective net 102 can be opened to inspect the components inside the air compressor, and the protective net 102 can be disassembled for cleaning.

[0028] See also Figure 1 and Figure 4 As shown, an air compressor comprises an air compressor body 2 arranged on the outer wall of a production mounting frame 1, a mounting and fixing component 3 is installed on the top of the air compressor body 2, and a movable fixing component 4 is connected to the side of the air compressor body 2; the mounting and fixing component 3 comprises a fixing frame 301, a U-shaped card plate 302, a third spring 303, and a protrusion 304, which can fix the air compressor body 2 firmly to avoid excessive vibration that affects the use of the device, the fixing frame 301 forms a detachable structure with the air compressor body 2 through the U-shaped card plate 302 and the protrusion 304, and the protrusion 304 forms an elastic structure with the fixing frame 301 through the U-shaped card plate 302, the third spring 303, the air compressor body 2 can be engaged by the fixing frame 301, and the fixing frame 301 can be conveniently fixed by the U-shaped card plate 302 and the protrusion 304, so that the air compressor body 2 can be fixed to avoid excessive vibration during its operation, and the operation is simple and easy to use.

[0029] See also Figure 1 and Figure 5 As shown, an air compressor, a movable fixing component 4, includes a connecting plate 401, a support plate 402, a threaded rod 403, a rotating ball 404, and a fixing block 405, which can fix the air compressor to prevent it from being displaced during operation. The threaded rod 403 and the connecting plate 401 form a threaded connection, and the connecting plate 401, the support plate 402 and the air compressor body 2 form a right-angled triangle with the air compressor body 2 and the connecting plate 401 as right-angled sides. When the air compressor body 2 needs to be fixed, the fixing block 405 can be driven to move by twisting the threaded rod 403. When the fixing block 405 is tightly fitted to the ground, the air compressor can be fixed to prevent it from being displaced during operation. At the same time, the triangular supporting structure can provide more stable supporting performance, thereby avoiding safety hazards and increasing the practicality of the device.

[0030] Working principle: First, when the air compressor body 2 needs to be used, it is moved to the specified position and the threaded rod 403 is rotated. At this time, the threaded rod 403 will lift and lower the fixing block 405. When the fixing block 405 is tightly fitted with the ground, the air compressor body 2 can be fixed. At this time, the triangular structure formed by the connecting plate 401, the supporting plate 402 and the air compressor body 2 can make the air compressor body 2 more stable. Then, the fixing frame 301 is engaged with the air compressor body 2, and the U-shaped clamping plates 302 on both sides are bent toward one side of the fixing frame 301. At this time, the U-shaped clamping plates 302 will squeeze the third spring 303 and move with the protrusion 304. After the fixing frame 301 completely engages the air compressor body 2, the U-shaped clamping plates 302 are released. Under the action of the elastic force of the third spring 303 itself, the protrusion 304 can be pushed and engaged with the bottom plate at the bottom. At this time, the air compressor body 2 can be fixed.

[0031] Next, during the operation of the air compressor body 2, the air compressor body 2 draws air from the outside. At this time, the protective net 102 can isolate impurities such as dust in the outside air to prevent them from entering the inside of the air compressor body 2. At the same time, when it is necessary to inspect and repair the components inside the air compressor body 2, press the second latch 108. At this time, the second latch 108 will squeeze the second spring 107 and retract into the fixed seat 106. At this time, the protective net 102 can be rotated through the first latch 105 and the rotating shaft 103 to inspect and repair the components inside. In addition, the first latch 105 can be pressed again so that the first latch 105 squeezes the first spring 104 and retracts into the rotating shaft 103, and the protective net 102 can be disassembled so that it can be cleaned.
