Detailed implementation mode

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, a screw air compressor in an embodiment of the present utility model includes a base 11, on which a compressor body and other devices are arranged. The base 11 is detachably connected to the outer shell 12, facilitating the maintenance of the devices on the base 11.

[0027] Refer Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, support legs 13 are fixedly connected to the four corners of the bottom of the base 11. A support plate 21 is arranged below the base 11, and the support plate 21 is located inside the support legs 13. A slide groove 24 is formed on the side of the support leg 13 facing the support plate 21, and a slide block 23 matching the slide groove 24 is fixedly connected to the support plate 21. That is, the slide block 23 can slide up and down in the slide groove 24, thereby driving the support plate 21 and the caster 22 to move up and down. Support frames 51 are respectively rotatably connected to both sides of the base 11.

[0028] Furthermore, a first fixing hole 31 and a second fixing hole 32 that match each other are formed in the support leg 13, a third fixing hole 33 is formed in the slide block 23, and a fourth fixing hole 34 is formed in the support plate 21. The first fixing hole 31, the second fixing hole 32, the third fixing hole 33, and the fourth fixing hole 34 match each other. A fixing rod 35 is inserted between the first fixing hole 31, the third fixing hole 33, and the fourth fixing hole 34 to fix the support plate 21 on the support leg 13.

[0029] There is a gap between the upper end of the support frame 51 and the upper surface of the outer shell 12. A sheath 52 is provided on the support frame 51. It is convenient to lift the air compressor through the support frame 51 and the sheath 52, so that the support legs 13 leave the ground. Pull out the fixing rod 35, and the support plate 21 drives the casters 22 to move downward automatically. The casters 22 contact the ground. Insert the fixing rod 35 between the second fixing hole 32, the third fixing hole 33 and the fourth fixing hole 34 to fix the support plate 21 on the support leg 13. Stop lifting the air compressor, and it is convenient to move the air compressor through the casters 22.

[0030] Furthermore, a counterweight 41 is fixedly connected above the slider 23. The weight of the slider 23 can be increased through the counterweight 41 to prevent the friction force between the slider 23 and the chute 24 from being too large, resulting in the slider 23 being unable to slide downward automatically along the chute 24. A limiting plate 42 is fixedly connected inside the support leg 13. The upper surface of the limiting plate 42 is tangent to the second fixing hole 32. The slider 23 can be limited through the counterweight 41. When the slider 23 slides to contact the limiting plate 42, the second fixing hole 32, the third fixing hole 33 and the fourth fixing hole 34 are aligned, which is convenient to quickly insert the fixing rod 35 between the second fixing hole 32, the third fixing hole 33 and the fourth fixing hole 34. A handle 36 is fixedly connected to the fixing rod 35, which is convenient to pull out the fixing rod 35.

[0031] External threads are provided at the end of the fixing rod 35, and internal threads matching the external threads are provided in the fourth fixing hole 34. That is, the end of the fixing rod 35 can be threadedly connected into the fourth fixing hole 34. The fixing rod 35 is not easily detached automatically, and at the same time, it is also convenient to pull out the fixing rod 35, without increasing the time for installing and loosening the fixing rod 35 too much. The support plate 21 is in an I shape and has high stability.

[0032] See Figure 5 As shown, one end of the support frame 51 is rotatably connected to the side of the base 11 through a rotating shaft 54. The support frame 51 can be rotated to one side of the air compressor to act as a push rod, which is convenient to cooperate with the casters 22 to push the air compressor. On the other hand, the support frame 51 can be rotated to a position that does not affect the disassembly of the outer shell 12.

[0033] At the same time, during the assembly process of the air compressor, the devices on the base 11 are located at different positions. It is necessary to move the base 11 to each working station for assembly. It is also convenient to pull the base 11 and the devices already assembled on the base 11 through the support frame 51, which saves time and effort.

[0034] See Figure 6As shown in the figure, a protective frame 61 is fixedly connected to the support frame 51. A fifth fixing hole 53 is formed on the outer side of the support frame 51. An elastic rod matching the fifth fixing hole 53 is fixedly connected to the inner side of the protective frame 61. The elastic rod can be inserted into the fifth fixing hole 53 to fixedly connect the protective frame 61 to the support frame 51. The cooperation between the protective frame 61 and the support frame 51 can play a role in protecting the air compressor, and external impacts can be avoided during the operation and transportation of the air compressor.

[0035] During use, refer to Figures 1 to 6 As shown in the figure, the air compressor is supported by the support legs 13 fixedly connected to the bottom of the base 11. When the air compressor needs to be moved, the air compressor is lifted by the support frames 51 on both sides. The fixing rod 35 is loosened, so that the slider 23 and the support plate 21 slide downward, and the casters 22 contact the ground. The fixing rod 35 is normally inserted between the second fixing hole 32, the third fixing hole 33 and the fourth fixing hole 34 to fix the support plate 21. The air compressor can be easily moved through the casters 22. The air compressor is moved to the working position, the air compressor is lifted again, the support plate 21 is moved to the initial position, and the support legs 13 contact the ground to stably support the air machine.

[0036] Compared with the prior art, a screw air compressor of the present invention can switch between supporting and moving the air compressor, which is convenient for moving and supporting.
