[0002] An air compressor is an electrical device used to compress gas, including internal core parts and a sheet metal housing, and is widely used in factories and research institutions.

[0003] In the prior art, most air compressors fix the air filter on the electric box. However, since the inside of the electric box is full of electronic components, and due to the arrangement of the parts, the electric box basically only fixes four bolts at the four corners of the bottom plate. When the air filter operates, it will cause the electric box to vibrate. In such a working condition for a long time, it is very likely that the electronic components inside the electric box will fail. Based on this reason, Chinese Patent Publication No. CN216223441U discloses a fixing structure for an air filter. Through this fixing structure, the air filter can be fixed on the door panel. The door panel and the parts connected to the door panel are all sheet metal structures, which are not only stable but also can avoid the failure of electronic components.

[0004] However, when the above patent is used, there are still some disadvantages. When the air filter is fixedly installed, although it is installed on the door panel and can avoid the failure of electronic components, since its installation height is fixed, it is not convenient to connect the air inlet and outlet of the air filter to the external pipeline, which brings inconvenience to the work and has insufficient practicability. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a fixing structure for an air filter that can adjust the fixing height of the air filter, is convenient for connecting the air inlet and outlet of the air filter to the external pipeline, brings convenience to the work, and improves the practicability.

At both the upper and lower ends inside the I-shaped frame, there are limit grooves communicating with the guide holes. Two groups of fixing plates are symmetrically and fixedly connected to the I-shaped frame. Positioning rods are slidably arranged in all four groups of guide holes. Limit blocks are fixedly arranged on each group of positioning rods and are matched with the limit grooves. Movable plates are fixedly connected to the front two groups of limit blocks and the rear two groups of limit blocks. Springs are fixedly connected to the inner ends of the two groups of movable plates. The inner ends of the two groups of springs are respectively fixedly connected to the outer ends of the two groups of fixing plates. A plurality of groups of positioning holes are equidistantly arranged on the inner walls of the front and rear sides of the door panel. The I-shaped frame is installed on the door panel through the cooperation of the positioning rods and the positioning holes. The clamping mechanism includes a clamping seat and an arc-shaped clamping ring. A connecting plate is fixedly connected to the left end of the clamping seat. Four connecting bolts are inserted into the connecting plate. Four threaded connection holes are provided on the right end of the I-shaped frame and are matched with the connecting bolts. The connecting plate is fixedly installed on the I-shaped frame through the threaded cooperation of the connecting bolts and the threaded connection holes. Two groups of ear plates are integrally fixedly provided on both sides of the clamping seat and the arc-shaped clamping ring. Two docking bolts are screwed on the upper two groups of ear plates and the lower two groups of ear plates respectively.

[0008] Preferably, fastening rubber pads are fixedly connected to the inner arc surfaces of the clamping seat and the arc-shaped clamping ring.
