[0026] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0028] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments.

[0029] Referring to Figures 1-5 , the present embodiment provides an adjustable support leg, comprising a base 100, a threaded rod 200, a bracket 300 and a first nut 400.

[0030] Specifically, the first threaded hole 101 is arranged at the top center of the base 100, and the bottom of the threaded rod 200 can be screwed into the first threaded hole 101.

[0031] With reference to Figure 4 The support 300 is in the shape of a triangular inclined strut, and an adjusting hole 301 is arranged on one side of the support 300. In this embodiment, the adjusting hole 301 is a threaded hole and can be matched with the threaded rod 200. A plurality of first mounting holes 302 are arranged on the other side of the support 300, and are used for mounting the equipment. When the support 300 is limited by the equipment (cannot rotate), the support 300 can move along the axial direction of the threaded rod 200 when the threaded rod 200 is rotated, and when applied to the equipment, the height of the equipment can be adjusted when the threaded rod 200 is rotated.

[0032] Preferably, a first nut 400 and a second nut 500 are sleeved on the threaded rod 200 near the two sides of the adjusting hole 301. A first gasket 600 is also sleeved between the first nut 400 and the support 300. The first nut 400, the second nut 500 and the first gasket 600 are used to fix the relative position between the threaded rod 200 and the support 300. That is, when the height of the support 300 needs to be adjusted, the first nut 400 and the second nut 500 are loosened first so that they are away from the support 300, and then the threaded rod 200 is rotated to adjust the height of the support 300. After the adjustment is completed, the first nut 400 and the second nut 500 are tightened again. If there is no first nut 400 and second nut 500, the threaded rod 200 can be loosened due to the vibration of the equipment during operation, so that the height between the support 300 and the base 100 changes.

[0033] Preferably, a third nut 700 and a second gasket 800 are sleeved at the position where the threaded rod 200 is connected with the base 100, and are used to fix the relative position between the threaded rod 200 and the base 100. That is, when the height of the support 300 needs to be adjusted, the first nut 400 and the second nut 500 are loosened first so that they are away from the support 300, and then the third nut 700 is loosened, and then the threaded rod 200 is rotated for adjustment. If there is no third nut 700 and second gasket 800, the threaded rod 200 can be loosened due to the vibration of the equipment during operation, so that the relative position between the threaded rod 200 and the base 100 changes.

[0034] Preferably, in order to facilitate the rotation of the threaded rod 200, the top of the threaded rod 200 is hexagonal, which facilitates the rotation of the threaded rod 200 by using a wrench or the like.

[0035] In order to stabilize the device and slow down the vibration of the device, the base 100 is preferably arranged in a 'U' shape, and a plurality of second mounting holes 102 are arranged on two sides of the base 100 for fixing the base 100 to the ground or other reference surface. A rubber pad can be additionally arranged between the base 100 and the ground or other reference surface to reduce vibration.

[0036] With reference to Figure 6 As an alternative embodiment, the adjusting hole 301 on the bracket 300 is a common round hole, a non-threaded hole, and the diameter is slightly larger than the outer diameter of the threaded rod 200. That is, the bracket 300 and the threaded rod 200 are clearance fit. The rest of the structure is the same as described above.

[0037] In this embodiment, when the height of the bracket 300 needs to be adjusted, the second nut 500 is loosened to move away from the bracket 300, and then the threaded rod 200 is kept stationary (one hand can use a wrench to fix the top of the threaded rod 200), and then the first nut 300 is twisted using a wrench, and the first nut 300 will move up and down against the bracket 300. After adjustment, the first nut 300 is tightened again.

[0038] With reference to Figure 7 The application also provides a sorting machine, which comprises the adjustable support leg described above.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
