A protective net and a matching slide rail are provided, so that the protective net can be removed at any time for easy maintenance and replacement. Auxiliary protective nets are provided at both ends of the main protective net. The auxiliary protective nets are locked and positioned by nuts, and the protection angle can be adjusted.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. In the above case, the air compressor is protected by installing a protective net on the outside of the air compressor. However, the air compressor is prone to vibration during use. Generally, the air compressor is fixed to a base or the ground by bolts, which makes it inconvenient to carry the air compressor. Of course, air compressors with rollers are also produced on the market, but the stability of the rollers is limited, which can easily cause the air compressor to shake.

[0005] Therefore, we propose a protective structure for an air compressor that can solve the above problems. Utility Model Content

[0009] As an optional solution of the technical solution of the present application, the slide bar and the slide groove are in a cross shape, and the sizes of the universal wheel and the slide groove match.

[0010] As an optional solution of the technical solution of the present application, four corners of the inner wall at the bottom end of the slide groove are all penetrated with openings, and the universal wheel is movably connected to the openings.

[0011] As an optional solution of the technical solution of the present application, a water inlet is opened through the upper end of the inner wall on one side of the water tank, and a water outlet is opened through the lower end of the inner wall on the other side of the water tank, and the inner sides of the water inlet and the water outlet are movably connected with blockages.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: through the combination of the connecting rod, the small bevel gear and the large bevel gear, the screw rod can be driven to rotate, and the sliding bar is slidably connected to the sliding groove. During the rotation of the screw rod, the universal wheel on the bottom side of the sliding bar can be driven to be retracted into the sliding groove, so that the bottom end of the protective base is in contact with the ground, and water is poured into the water tank through the water inlet.

[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a protective structure for an air compressor, comprising an air compressor body 1, a protective base 11 is fixedly installed at the bottom end of the air compressor body 1, and also comprises a slide 12 and a water tank 13. The slide 12 is arranged in the middle of the protective base 11, and a slide bar 14 is slidably connected inside the slide 12. Universal wheels 15 are fixedly installed at the four corners at the bottom end of the slide bar 14. The slide bar 14 and the slide 12 are in a cross shape. Through holes 16 are penetrated at the four corners of the inner wall at the bottom end of the slide 12. The universal wheels 15 are movably connected with the through holes 16. The sizes of the universal wheels 15 and the slide 12 are matched. A screw rod 2 is vertically penetrated through the middle of the slide bar 14 and is threadedly connected. The screw rod 2 is rotatably connected to the inner wall of the top and bottom ends of the slide 12 through bearings.

[0018] In this technical solution, the slide bar 14 is slidably connected to the slide groove 12, and the screw rod 2 is threadedly connected to the middle part of the slide bar 14. During the rotation of the screw rod 2, the slide bar 14 can be driven to move up and down in the slide groove 12. When the slide bar 14 moves upward, it can drive the four sets of universal wheels 15 to be retracted into the slide groove 12, so that the bottom end of the protective base 11 is in contact with the ground, thereby increasing the contact area between the protective base 11 and the ground. When the slide bar 14 moves downward, it can push the four sets of universal wheels 15 to move out of the slide groove 12 and in contact with the ground, thereby facilitating the movement of the air compressor body 1 for adjusting the use position.

[0019] In this embodiment, a connecting groove 21 is opened above the slide groove 12, and the end of the screw rod 2 placed on the inner side of the connecting groove 21 passes through and is fixedly installed with a large bevel gear 22. One side of the connecting groove 21 is horizontally rotatably connected to a connecting rod 23 through a bearing. The connecting rod 23 is placed on one end of the inner side of the connecting groove 21 and is fixedly installed with a small bevel gear 24. The small bevel gear 24 is meshed with the large bevel gear 22. The connecting rod 23 is placed on the outer side of the protective base 11 and is fixedly installed with a turntable 25.

[0020] In this technical solution, the staff can rotate the small bevel gear 24 at one end of the connecting rod 23 through the turntable 25, and the small bevel gear 24 is engaged with the large bevel gear 22. During the rotation of the small bevel gear 24, the screw rod 2 in the middle of the large bevel gear 22 can be driven to rotate.

[0021] In this embodiment, the water trough 13 is opened on the outside of the slide 12, and a water inlet 3 is opened through the upper end of the inner wall of one side of the water trough 13, and a water outlet 31 is opened through the lower end of the inner wall of the other side of the water trough 13, and the inner sides of the water inlet 3 and the water outlet 31 are movably connected with a plug 32.

[0022] In this technical solution, water is poured into the water tank 13 through the water inlet 3. On the one hand, the weight of the protective base 11 can be increased, thereby improving the stability of the protective base 11 in use. On the other hand, the water in the water tank 13 can absorb the vibration generated when the air compressor body 1 is working, thereby further improving the stability of the air compressor during use. By removing the plug 32 on the inner side of the water outlet 31, the water in the water tank 13 can be discharged, thereby reducing the weight of the protective base 11 and facilitating the movement of the air compressor body 1.

[0023] When a protective structure for an air compressor is used, a worker can rotate the small bevel gear 24 at one end of the connecting rod 23 through the turntable 25, and the small bevel gear 24 meshes with the large bevel gear 22. During the rotation of the small bevel gear 24, the screw rod 2 in the middle of the large bevel gear 22 can be driven to rotate, and the slide bar 14 is slidably connected to the slide groove 12. The screw rod 2 is threadedly connected to the middle part of the slide bar 14. During the rotation of the screw rod 2, the slide bar 14 can be driven to move up and down in the slide groove 12. When the slide bar 14 moves upward, the four sets of universal wheels 15 can be driven to be retracted into the slide groove 12, so that the bottom end of the protective base 11 fits with the ground, thereby improving the contact between the protective base 11 and the ground. Contact area, when the slide bar 14 moves downward, it can push the four sets of universal wheels 15 out of the slide groove 12 and fit with the ground, which is convenient for pushing the air compressor body 1 to move and adjust the use position. Water is injected into the water tank 13 through the water inlet 3. On the one hand, it can increase the weight of the protective base 11 and improve the use stability of the protective base 11. On the other hand, the water in the water tank 13 can absorb the vibration generated when the air compressor body 1 is working, and further improve the stability of the air compressor during use. Removing the plug 32 on the inner side of the water outlet 31 can drain the water in the water tank 13, reduce the weight of the protective base 11, and facilitate the movement of the air compressor body 1.
