It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] See also Figure 1 and Figure 2 Now, a rotatable lifting structure provided by the utility model is described. A rotatable lifting structure includes a leg tube 1, a bearing seat 3, a bearing sleeve 6 and a connecting support 8. The upper part of the leg tube 1 is circumferentially provided with an external thread, the bearing seat 3 is sleeved on the upper part of the leg tube 1 and is threadedly connected to the leg tube 1, a bearing body 4 is installed inside the bearing seat 3, the bearing sleeve 6 is sleeved on the lower part of the leg tube 1 and slides along the axial direction of the leg tube 1, the upper end of the bearing sleeve 6 penetrates the bearing seat 3 and is connected to the bearing body 4, and the connecting support 8 is connected to the lower end of the bearing sleeve 6.

[0027] The utility model provides a rotatable lifting structure. Compared with the prior art, the bearing seat 3 is sleeved on the upper part of the leg tube 1 and is threadedly connected to the leg tube 1. The bearing sleeve 6 is sleeved on the lower part of the leg tube 1 and is slidably matched with the leg tube 1. The upper end of the bearing sleeve 6 penetrates the bearing seat 3 and is connected to the bearing body 4 in the bearing seat 3. The connecting support 8 is connected to the lower end of the bearing sleeve 6. The connecting support 8 is used to support the chassis. When the rotatable lifting structure provided by the utility model is used, the bearing seat 3 is rotated to realize the rotation and lifting of the bearing seat 3 through the threaded connection structure between the bearing seat 3 and the upper part of the leg tube 1. The bearing seat 3 drives the bearing sleeve 6 to slide up and down along the axial direction of the leg tube 1 through the bearing body 4, thereby realizing the lifting and lowering of the connecting support 8. The chassis is placed on the connecting support 8, and finally the lifting and lowering of the chassis is realized. When the connecting support 8 drives the chassis to descend to a predetermined position, the connecting support 8 is pushed horizontally, and the bearing sleeve 6 cooperates with the bearing body 4 to rotate along the leg tube 1, thereby driving the chassis to rotate through the connecting support 8, removing the assembled tank body, and performing subsequent operations. The utility model provides a rotatable lifting structure, which removes the additional support required by the prior art, reduces the attachment of the device itself, greatly reduces the installation area of ​​the device, reduces the environmental requirements of the installation of the device, and saves installation space.

[0028] The rotatable lifting structure and the supporting legs provided by the utility model are combined into one, and the mounting seat or fixed shaft dedicated to the existing lifting mechanism is removed, thereby reducing the production cost of the equipment. By removing the mounting seat or fixed shaft dedicated to the existing lifting mechanism, the space on the outer surface of the equipment is increased, so as to facilitate the installation of other structural parts, and increase more forms or methods of product design layout. Since the rotatable lifting structure and the supporting legs are combined into one, the azimuth area of ​​the chassis rotating with the connection support 8 descending to the predetermined position is increased, so the selection of its installation position is more flexible and has higher adaptability to space.

[0029] A rotating hand wheel 5 is arranged on the outer periphery of the bearing seat 3, and the rotating hand wheel 5 is fixedly connected to the bearing seat 3. The rotating hand wheel 5 is a circular ring structure, and a plurality of connecting rods are radially arranged on the inner side of the rotating hand wheel 5, and the plurality of connecting rods are welded to the outer peripheral wall of the bearing seat 3.

A corresponding step is provided at the upper end of the bearing sleeve 6 which penetrates into the bearing seat 3 to achieve a clamping fit with the bearing body 4, and the bearing sleeve 6 can rotate relative to the bearing body 4, but the two will not be separated longitudinally due to the limit of the step.

[0031] In addition, the lower end of the bearing sleeve 6 is detachably connected to a lower end plate, which is connected to the lower end of the bearing sleeve 6 by bolts. An inner hole larger than the outer diameter of the support leg tube 1 is opened in the middle of the lower end plate, and the inner hole of the lower end plate and the outer peripheral wall of the support leg tube 1 form an installation gap.

[0032] The upper part of the leg tube 1 is sleeved with a threaded protective tube 2, which is arranged at the upper end of the bearing seat 3. The threaded protective tube 2 shields the external thread of the leg tube 1, prevents the external thread of the leg tube 1 from being exposed, prevents pollution from dust in the external space, and plays a role in beautifying the appearance.

[0033] Please refer to Figure 2 The lower inner peripheral wall of the bearing sleeve 6 is provided with an installation groove, and a sliding sleeve 7 is provided in the installation groove. The sliding sleeve 7 is sleeved on the outside of the leg tube 1 and slides with the leg tube 1. The sliding sleeve 7 can reduce the wear of the bearing sleeve 6 and the leg tube 1, reduce energy loss, and reduce noise.

[0034] Specifically, the connecting support 8 includes a mounting sleeve and a support arm. The mounting sleeve is mounted on the lower end of the bearing sleeve 6, and a mounting plate is provided on the lower end of the mounting sleeve. The mounting plate is detachably connected to the lower end of the bearing sleeve 6 by bolts. One side of the support arm is welded and fixed to the outer wall of the mounting sleeve, and the other side of the support arm extends horizontally outward to form a supporting platform for supporting the chassis.
