[0017] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-7 An adjustable cold storage mobile caster assembly according to an embodiment of the present invention includes a support base 1 and a cold storage box 2. A base plate 3 is provided at the bottom of the cold storage box 2, and a fixing screw 4 is provided at the bottom of the base plate 3. A mobile pulley 5 is provided at the bottom of the support base 1. A positioning bearing 6 and a fixing tube 7 are provided on the surface of the support base 1. A hydraulic cylinder 8 is provided inside the fixing tube 7. A limit rod 9 is provided at the lifting end of the hydraulic cylinder 8. A mounting plate 10 is provided on the surface of the limit rod 9. An observation port 11 is provided on the side of the support base 1. Multiple sets of observation ports 11 are provided, one of which... An upright plate 12 is provided on the inner surface of the observation port 11. A threaded hole is provided on the side of the upright plate 12, and a limiting screw 13 is screwed into the threaded hole. First, the movable pulley 5 can be used to easily move the cold storage box 2 to a suitable position. In addition, when it is necessary to adjust the angle of the cold storage box 2, the limiting screw 13 is loosened to separate one end of the limiting screw 13 from the side of the limiting rod 9. Then, the positioning bearing 6 can be used in conjunction with the fixing tube 7 to easily adjust the angle of the base plate 3, so that the cold storage box 2 can be rotated. The hydraulic cylinder 8 is fixedly connected to the inner side of the fixing tube 7.

[0018] Please see Figures 1-3As shown, a curtain 14 is provided on the upper surface of the observation port 11. One end of the limiting screw 13 abuts against the side of the limiting rod 9. The positioning bearing 6 is fixedly connected to the surface of the support base 1, and the fixing tube 7 is fixedly connected to the inner ring surface of the positioning bearing 6. The opening of the observation port 11 allows for easy observation of the operation of the internal structure of the support base 1, and also facilitates subsequent inspection of the equipment by staff. In addition, the curtain 14 can cover the observation port 11, preventing the internal structure of the support base 1 from being directly exposed to the outside world through the observation port 11, which also affects the aesthetics to a certain extent.

[0019] Please see Figures 3-6 As shown, the mounting plate 10 has a through hole on its surface. One end of the fixing screw 4 passes through the through hole on the surface of the mounting plate 10. A positioning nut 15 is screwed onto the surface of the fixing screw 4. The limiting rod 9 is fixedly connected to the lifting end of the hydraulic cylinder 8. The cold storage box 2 is fixedly connected to the surface of the base plate 3. A positioning groove 20 is provided on the side of the limiting rod 9. First, the fixing screw 4 can be inserted into the mounting plate 10, and then the positioning nut 15 can be used to fix it, thereby facilitating the fixed installation of the base plate 3 and the mounting plate 10. In addition, when the cold storage box 2 rotates by the positioning bearing 6, it can... The limiting screw 13 is rotated so that one end of the limiting screw 13 is inserted into the positioning groove 20 opened on the side of the limiting rod 9, thereby positioning the rotated cold storage box 2. Multiple sets of positioning grooves 20 are opened to facilitate multi-angle adjustment of the cold storage box 2. In addition, when a short-term height adjustment of the cold storage box 2 is required, the hydraulic cylinder 8 can be activated to lift the limiting rod 9, thereby raising the height of the cold storage box 2 installed on the base plate 3. When not in use, the limiting rod 9 can be placed on the end face of the fixing pipe 7 to reduce the pressure of the base plate 3 and the cold storage box 2 on the lifting end of the hydraulic cylinder 8.

When the base plate 3 is rotated by the positioning bearing 6, the friction of the bottom of the base plate 3 can be reduced by the cooperation of the mounting bracket 17 and the support wheel 19, which facilitates the rotation of the cold storage box 2. In addition, the mounting bracket 17 and the support wheel 19 also facilitate the support of the bottom of the base plate 3. Thus, together with the limiting rod 9 and the fixing tube 7, the support stability of the bottom of the base plate 3 can be increased.

[0021] Through the above-described solution of this utility model, multiple sets of movable pulleys 5 are provided at the bottom of the support base 1 to facilitate the displacement of the cold storage box 2. After the movable pulleys 5 are positioned, the limiting screw 13 is loosened to disengage from the positioning groove 20, thereby making it easy for the base plate 3 to rotate in conjunction with the positioning bearing 6, thus facilitating the adjustment of the orientation of the cold storage box 2 and making it convenient for use.
