[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] See also Figure 1-5The utility model provides a technical solution: a new screw air compressor that is easy to use, including an air compressor 1, a fixed support leg 2 is fixedly connected to the lower surface of the air compressor 1, four rollers 3 are arranged below the air compressor 1, and the upper surfaces of the four rollers 3 are fixedly connected to a moving column 4, the interior of the air compressor 1 is arranged to be hollow, and the upper surface of the moving column 4 slides through the interior of the air compressor 1, a cylinder 5 is fixedly connected to the top wall of the air compressor 1, a force plate 6 is fixedly connected to the side surfaces of the front and rear moving columns 4, and the output end of the cylinder 5 contacts the upper surface of the force plate 6, and a triangular locking block 7 is fixedly connected to the side surfaces of the left and right moving columns 4, and a partition 11 is fixedly connected to the inner wall of the air compressor 1, and two sliding grooves are provided on the upper surface of the partition 11. 8. The interiors of the two sliding grooves 8 are both slidably connected with U-shaped plates 9. The adjacent side surfaces of the two U-shaped plates 9 are respectively fixedly connected with springs 10. The adjacent ends of the two springs 10 are respectively fixedly connected with the inner walls of the two sliding grooves 8. A driving assembly is arranged on the U-shaped plate 9. When it is necessary to control the air compressor 1 to move, the cylinder 5 cooperates with the force plate 6 to make the moving column 4 move downward. After the moving column 4 moves downward, it will synchronously drive the roller 3 to move. The roller 3 contacts the ground to lift the air compressor 1 and makes the fixed support leg 2 break away from the ground. Through the above structure, when the air compressor 1 is moved, the friction between the air compressor 1 and the ground can be reduced through the cooperation of the cylinder 5 and the roller 3, so that the air compressor 1 can be pushed more easily.

[0025] When the moving column 4 moves, the inclined surface of the triangular locking block 7 contacts with the U-shaped plate 9, and the U-shaped plate 9 is forced to move by means of the inclined surface. When the U-shaped plate 9 moves, the spring 10 is compressed. After the U-shaped plate 9 passes through the triangular locking block 7, the spring 10 resets the U-shaped plate 9. At this time, the cylinder 5 is retracted. Through the above structure, the U-shaped plate 9 and the triangular locking block 7 can be used to replace the cylinder 5 to complete the load-bearing work after being pushed out. The stretching time of the cylinder 5 is short in the whole process. Compared with the traditional structure, the service life of the cylinder 5 can be effectively and significantly improved.

[0026] Further, the driving assembly includes two annular sleeves 12, which are respectively fixedly connected to the lower surfaces of the two U-shaped plates 9. The upper surface of the partition 11 is provided with a through groove extending from its lower surface. The lower side of the annular sleeve 12 extends from the lower surface of the partition 11 through the through groove. The inner wall of the air compressor 1 is rotatably connected with a bidirectional threaded rod 13. The two opposite threads of the bidirectional threaded rod 13 are respectively threaded with threaded sleeves 24. The surfaces of the two threaded sleeves 24 on one side are fixedly connected with a sliding rod 25. The annular sleeve 12 is slidably sleeved on the outer surface of the sliding rod 25. The right end of the bidirectional threaded rod 13 rotates and penetrates the right side surface of the air compressor 1. When it arrives at the designated location, the cylinder 5 is used again to push the air compressor 1. The force-bearing plate 6 is held, and then the bidirectional threaded rod 13 is rotated. After the bidirectional threaded rod 13 is rotated, the threaded sleeve 24 is limited by the annular sleeve 12 and cannot be rotated. Therefore, when the bidirectional threaded rod 13 rotates, it will synchronously move in the horizontal direction, and then the threaded sleeve 24 is used to push the annular sleeve 12 to move. When the two annular sleeves 12 approach each other, the two U-shaped plates 9 will be driven to approach each other, thereby disengaging the U-shaped plates 9 from the triangular locking block 7, and then the cylinder 5 can be slowly retracted. Through the above structure, it can make it more convenient to retract the roller 3, and whether it is retracting the roller 3 or pushing out the roller 3, the cylinder 5 only needs to move for a short time, which effectively reduces the probability of its damage.

[0027] Furthermore, a limiting groove 14 is provided on the left side surface of the air compressor 1, and a power cord 15 is arranged on the left side surface of the air compressor 1. The inner walls on the upper and lower sides of the limiting groove 14 are rotatably connected with a second bidirectional threaded rod 16, and the outer surface of the second bidirectional threaded rod 16 is threadedly sleeved with a moving block 17, and the two moving blocks 17 are both slidably connected to the limiting groove 14. The left side surfaces of the two moving blocks 17 are fixedly connected with an L-shaped rod 18, and the two L-shaped rods 18 are arranged in a mirror image. The outer surface of the second bidirectional threaded rod 16 is sleeved with a worm gear 19, and the outer surface of the worm gear 19 is meshingly connected with a worm 20. The front end of the worm 20 rotates and penetrates into the interior of the air compressor 1, and the front end of the worm 20 is fixedly connected with a bevel gear 21, and the outer surface of the bevel gear 21 is meshingly connected with a second bevel gear 22. The left side surface of the second bevel gear 22 is fixedly connected with a rotating rod 23, and the left end of the rotating rod 23 rotates and penetrates out of the left side surface of the air compressor 1. When the air compressor 1 is transported, the power cord 15 The power line 15 is wound around the two L-shaped rods 18 and a slipknot is tied with the power line 15 itself, and then the rotating rod 23 is used to drive the second bevel gear 22 to rotate, and the second bevel gear 22 cooperates with the first bevel gear 21 to drive the worm 20 to rotate. After the worm 20 rotates, the worm wheel 19 is used to synchronously drive the second bidirectional threaded rod 16 to rotate. Since the movement block 17 is limited by the limiting groove 14, when the second bidirectional threaded rod 16 rotates, it will synchronously drive the two movement blocks 17 to move, and when the movement block 17 moves, the L-shaped rod 18 will move synchronously, so that the power line 15 is in a taut state to avoid the power line 15 from shaking violently or even falling off the L-shaped rod 18 due to the undulations of the road surface during transportation. Through the above structure, the power line 15 can remain stationary during the transportation of the air compressor 1 to avoid causing trouble to the unloading staff after it is scattered, and it can also avoid the power line 15 from being scattered and damaged during the transportation process.

[0028] Working principle: when it is necessary to control the air compressor 1 to move, the cylinder 5 cooperates with the force plate 6 to make the moving column 4 move downward. After the moving column 4 moves downward, it will synchronously drive the roller 3 to move. The roller 3 contacts the ground to lift the air compressor 1 and make the fixed support leg 2 out of contact with the ground, and when the moving column 4 moves, the inclined surface of the triangular locking block 7 contacts the U-shaped plate 9, and forces the U-shaped plate 9 to move with the help of the inclined surface. When the U-shaped plate 9 moves, it will compress the spring 10. After the U-shaped plate 9 passes through the triangular locking block 7, the spring 10 resets the U-shaped plate 9. At this time, the cylinder 5 is retracted. When arriving at the designated location, the cylinder 5 is used again to support the force plate 6, and then the bidirectional threaded rod 13 is rotated. After the bidirectional threaded rod 13 rotates, the threaded sleeve 24 is limited by the annular sleeve 12 and cannot rotate. Therefore, when the bidirectional threaded rod 13 rotates, it will synchronously move in the horizontal direction, and then the threaded sleeve 24 is used to push the annular sleeve 12 to move. When the annular sleeves 12 are close to each other, the two U-shaped plates 9 will be driven to approach each other, thereby causing the U-shaped plates 9 to disengage from the triangular locking block 7, and then the cylinder 5 can be slowly retracted. When the air compressor 1 is transported, the power cord 15 can be wrapped around the two L-shaped rods 18 and a slipknot can be tied using the power cord 15 itself. Then, the rotating rod 23 is used to drive the second bevel gear 22 to rotate, and the second bevel gear 22 cooperates with the first bevel gear 21 to drive the worm 20 to rotate. After the worm 20 rotates, the worm gear 19 is used to synchronously drive the second bidirectional threaded rod 16 to rotate. Since the movement block 17 is limited in movement by the limiting groove 14, the two movement blocks 17 will be driven to move synchronously when the second bidirectional threaded rod 16 rotates. When the movement block 17 moves, the L-shaped rod 18 will move synchronously, so that the power cord 15 is in a taut state, so as to avoid the situation in which the power cord 15 shakes violently or even falls off from the L-shaped rod 18 due to the ups and downs of the road during transportation.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
