[0024] As shown in Figures 1-6 , the utility model provides a kind of technical scheme: an oil-free small scroll air compressor, including air compressor 1, the bottom of air compressor 1 is provided with the support mechanism 2 of improving the stability of air compressor 1, by setting up support mechanism 2, air compressor 1 can be supported, the roller at its bottom is suspended, air compressor 1 can be avoided to move due to equipment vibration in the operation process of air compressor 1, support mechanism 2 is provided with the adjusting mechanism 3 of adapting different topography, by setting up adjusting mechanism 3, support plate 27 can still effectively and stably support air compressor 1 on uneven ground.

[0025] ​​The support mechanism 2 comprises a crankshaft 21, an extension rod 22, a connecting rod 23, a worm gear 24, a worm 25, a handle 26, a support plate 27, and a rubber pad 28. One end of the crankshaft 21 is rotatably connected to the side wall of the air compressor 1, and the other end of the crankshaft 21 penetrates the air compressor 1 and is fixedly installed with the worm gear 24. The penetration part of the crankshaft 21 and the air compressor 1 is rotatably connected. The outer wall of the air compressor 1 is rotatably connected with the worm 25. The bottom of the worm 25 is fixedly installed with the handle 26. The worm 25 is engaged with the worm gear 24. By rotating the worm 25 through the handle 26, the two groups of worm gears 24 engaged with the worm 25 can make the two groups of crankshafts 21 rotate in opposite directions synchronously. One end of the extension rod 22 is fixedly installed at the bottom of the air compressor 1. The other end of the extension rod 22 is fixedly installed with the support plate 27. By abutting the support plate 27 to the ground and lifting the air compressor 1, the roller at the bottom of the air compressor 1 is separated from the ground. The air compressor 1 can be supported by the support plate 27, which can improve the friction between the air compressor 1 and the ground, avoid the air compressor 1 from moving due to equipment vibration during operation, and improve the friction between the support plate 27 and the ground by setting the rubber pad 28. The rubber pad 28 prevents the support plate 27 from sliding. One end of the connecting rod 23 is hingedly connected to the outer wall of the crankshaft 21. The other end of the connecting rod 23 is hingedly connected to the top of the support plate 27. By rotating the crankshaft 21, the connecting rod 23 and the extension rod 22 can drive the support plate 27 to move up and down.

[0026] The adjusting mechanism 3 comprises a threaded rod 31, a knob 32, a support rod 33, an inclined groove 34, a sliding block 35, and a crossbar 36. One end of the threaded rod 31 is rotatably connected to the inner wall of the support plate 27. The other end of the threaded rod 31 penetrates the support plate 27 and is fixedly installed with the knob 32. The penetration part of the threaded rod 31 and the support plate 27 is rotatably connected. By rotating the threaded rod 31 through the knob 32, the threaded rod 31 can drive the sliding block 35 connected with it by threads to slide on the inner wall of the support plate 27. The support rod 33 is slidably connected to the inner wall of the support plate 27 and penetrates the support plate 27. By sliding the support rod 33 downward and abutting it to the ground, the support plate 27 can be supported, avoiding the support plate 27 from shaking due to uneven ground. The support rod 33 is provided with the inclined groove 34. The inner wall of the sliding block 35 is threadedly connected with the outer wall of the threaded rod 31. The side wall of the sliding block 35 is fixedly installed with the crossbar 36. The sliding block 35 moves synchronously with the crossbar 36. The outer wall of the crossbar 36 abuts to the inner wall of the inclined groove 34. The crossbar 36 moves while pressing the inclined groove 34, which can make the support rod 33 slide up and down on the inner wall of the support plate 27.

[0027] Working principle: when the air compressor 1 needs to be started, first of all, the handle 26 is rotated to rotate the worm 25, and the two sets of worm gears 24 meshed with the worm 25 can make the two sets of crankshafts 21 rotate synchronously in opposite directions, at this time, the two sets of crankshafts 21 will extrude the connecting rods 23 downward, so that the connecting rods 23 extrude the supporting plate 27 downward, so that the supporting plate 27 moves downward and stretches the telescopic rod 22, until the supporting plate 27 adheres to the ground and lifts the air compressor 1, so that the bottom roller of the air compressor 1 can be lifted off the ground, at this time, the supporting plate 27 can support the air compressor 1, improve the friction between the air compressor 1 and the ground, avoid the air compressor 1 from moving due to equipment vibration during operation, and improve the stability of the air compressor 1.

[0028] When the uneven ground causes the supporting plate 27 to support the air compressor 1 to shake, the knob 32 is rotated to rotate the threaded rod 31, so that the threaded rod 31 drives the sliding block 35 connected with it to slide on the inner wall of the supporting plate 27 away from the knob 32, at the same time, the sliding block 35 will drive the cross rod 36 to move synchronously, and the cross rod 36 will extrude the inclined groove 34 while moving, so that the supporting rod 33 can slide downward on the inner wall of the supporting plate 27, so that the supporting rod 33 can adhere to the ground, at this time, the supporting rod 33 can support the supporting plate 27, avoid the supporting plate 27 from shaking due to uneven ground, and make the supporting plate 27 support the air compressor 1 stably, so as to further improve the stability of the air compressor 1.

[0029] The above general description of the present application is made in detail, but some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the present application, the modifications or improvements are within the scope of the present application.
