A fixed frame extending into the housing is provided on the top of the housing. A cooling fan located inside the fixed frame is provided on the inner top wall of the housing. Two shock-absorbing springs are provided on the bottom of the base plate. With this screw air compressor and its shock-absorbing mechanism, when the screw air compressor body vibrates, the base plate moves downward, compressing the shock-absorbing springs. The support rod pushes the movable rod to move and compress the buffer springs. The fixed plate pushes the horizontal plate to compress the springs, and the pulley slides inside the support column. The overall bottom of the device has excellent cushioning and shock absorption function, which helps to extend the service life of the screw air compressor.
[0004] However, the height of the shock-absorbing base of the aforementioned air compressor is fixed, and the height of the air compressor platform that needs to be installed in many places is mostly fixed. As a result, if the height does not match, a new air compressor cannot be installed. Overall, its applicability is still somewhat limited. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The screw air compressor with a shock-absorbing mechanism on the base involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figure 1-4 This utility model provides a screw air compressor with a shock-absorbing mechanism on the base, including a main body 1 of the screw air compressor and a shock-absorbing base 2. The shock-absorbing base 2 includes a top plate 3, a bottom plate 4, a shock absorber 5, a connecting rod 6, an adjustment component, a drive component, and a limiting component. The top plate 3 is fixedly connected to the bottom of the main body 1. The adjustment component is installed on the bottom plate 4. The top end of the shock absorber 5 is rotatably connected to the top plate 3. The top end of the connecting rod 6 is rotatably connected to the top plate 3, and the bottom end of the connecting rod 6 is rotatably connected to the bottom plate 4. The connecting rod 6 and the shock absorber 5 are in a cross shape. The bottom end of the shock absorber 5 is connected to the adjustment component, and the position of the bottom end of the shock absorber 5 is adjusted by the adjustment component. The drive component is installed on the bottom plate 4 and drives the adjustment component to operate. The limiting component is connected between the drive component and the adjustment component. Before the drive component drives the adjustment component to operate, it first releases the limiting component. At the same time, when the drive component stops driving, the limiting component automatically resets and re-limits the adjustment component.
[0024] In use, the bottom position of the shock absorber 5 can be adjusted by driving the adjustment component through the drive component, thereby changing the height adjustment between the top plate 3 and the bottom plate 4, realizing the installation height adjustment of the entire screw air compressor, effectively adapting to a variety of different installation heights. At the same time, after the drive component stops driving, the limit component will automatically limit the adjustment component, without the need for additional limiting, making it more convenient to use. Furthermore, there is no need to release any limit before use, making operation even simpler.
[0025] The adjustment assembly includes a first lead screw 7 and a first threaded seat 8. The first lead screw 7 is rotatably mounted on the base plate 4, and the threaded seat 8 is slidably mounted on the base plate 4. The threaded seat 8 is threadedly connected to the first lead screw 7, and the bottom end of the shock absorber 5 is rotatably connected to the threaded seat 8.
[0026] Thus, simply rotating the first lead screw 7 can drive the threaded seat 8 to move, thereby adjusting the position of the bottom end of the shock absorber 5, and ultimately achieving height adjustment between the top plate 3 and the bottom plate 4.
[0027] The drive assembly includes a second lead screw 9, a hollow turntable 10, and a friction disc 11. The second lead screw 9 is threaded through the middle of the first lead screw 7, and the threaded connection between the second lead screw 9 and the first lead screw 7 is not self-locking. The hollow turntable 10 is fixedly installed on the surface of the first lead screw 7, and the middle of the hollow turntable 10 is connected to the middle of the first lead screw 7. The friction disc 11 is disposed inside the hollow turntable 10, and the friction disc 11 is fixedly installed on the surface of the second lead screw 9. When the friction disc 11 is in close contact with the inner wall of the hollow turntable 10, the second lead screw 9 can drive the first lead screw 7 to rotate.
[0028] Thus, by simply rotating the second lead screw 9, the second lead screw 9 will move within the first lead screw 7. During this process, the second lead screw 9 will drive the hollow turntable 10 to move until the friction disk 11 is in close contact with the side of the hollow turntable 10. At this point, the rotation of the second lead screw 9 will drive the first lead screw 7 to rotate, thereby driving the threaded seat 8 to move.
[0029] The hollow turntable 10 and the surface of the friction disc 11 are provided with several friction protrusions, which facilitates the transmission between the friction disc 11 and the hollow turntable 10.
[0030] The limiting assembly includes a toothed groove 12, a locking block 13, a return spring 14, and a mounting rod 15. The toothed groove 12 is formed on the surface of the hollow turntable 10. The locking block 13 is slidably mounted on the side of the mounting rod 15, and the side of the locking block 13 is machined with locking teeth. The mounting rod 15 is fixedly mounted on the base plate 4. The return spring 14 is connected between the locking block 13 and the mounting rod 15, and the locking teeth on the locking block 13 engage with the toothed groove 12 under the action of the return spring 14.
[0031] In this way, the hollow turntable 10 can be limited, and in turn, the first lead screw 7 can be limited.
[0032] The drive assembly also includes a guide block 16, a guide groove 17, and a connecting frame 18. The guide block 16 is slidably mounted on the base plate 4. The guide groove 17 is opened on the bottom surface of the locking block 13 and is a wedge-shaped groove. When the guide block 16 slides, it can push the locking block 13 to slide through the guide groove 17. The connecting frame 18 is rotatably sleeved on the surface of the second lead screw 9 and can move synchronously with the second lead screw 9. At the same time, the connecting frame 18 is fixedly connected to the guide block 16.
[0033] Thus, when the second lead screw 9 moves, it will drive the guide block 16 to slide synchronously through the connecting frame 18. During the sliding process, the guide block 16 will push the locking block 13 to slide through the guide groove 17, thereby separating the locking teeth on the locking block 13 from the tooth groove 12, thereby releasing the limit on the first lead screw 7.
[0034] There are two sets of each of the locking block 13, the reset spring 14, the mounting rod 15, and the guide block 16, which are symmetrically distributed on both sides of the hollow turntable 10.
[0035] There are two sets of guide grooves 17 on the locking block 13, which are symmetrically distributed. At the same time, there is a groove on the guide block 16, with the two sides of the groove located on the two sides of the two guide grooves 17 respectively. When the guide block 16 slides back and forth, the guide block 16 can drive the locking block 13 to slide through the cooperation of the two sides of the groove and the guide groove 17.
[0036] Therefore, the complete usage process is as follows: First, place the entire screw air compressor at the installation location and limit the bottom. Then, when the installation height of the entire air compressor needs to be adjusted, simply rotate the second lead screw 9. The second lead screw 9 will move within the first lead screw 7. During this process, the second lead screw 9 will drive the guide block 16 to slide synchronously through the connecting bracket 18. During the sliding of the guide block 16, it will push the locking block 13 to slide through the guide groove 17, thereby causing the locking teeth on the locking block 13 to separate from the tooth groove 12. At this time, the first lead screw 7 is difficult to rotate due to the limitation of the shock absorber 5. The rotation of the second lead screw 9 will continue to pass through the first lead screw 7 until the friction disc 11 and the side of the hollow turntable 10 are in close contact. At this time, the rotation of the second lead screw 9 will drive the first lead screw 7 to rotate, thereby driving the threaded seat 8 to move, thereby adjusting the bottom position of the shock absorber 5, and finally realizing the height adjustment between the top plate 3 and the bottom plate 4, realizing the installation height adjustment of the entire screw air compressor, effectively adapting to a variety of different installation heights.
[0037] Meanwhile, during use, when the adjustment is completed and the second lead screw 9 is released, since the threaded connection between the second lead screw 9 and the first lead screw 7 is not self-locking, and since the bottom of the shock absorber 5 applies resistance to the first lead screw 7, under the action of the return spring 14, the locking block 13 will drive the guide block 16 to reset through the guide groove 17, and the guide block 16 will drive the second lead screw 9 to reset through the connecting bracket 18 until the locking teeth of the locking block 13 engage with the tooth groove 12 on the surface of the hollow turntable 10. At this time, the first lead screw 7 will be repositioned. In this way, during use, the vibration of the base will not cause the first lead screw 7 to rotate, effectively maintaining the operational stability of the entire screw air compressor.
[0038] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
