[0023] The protective cover mechanism 2 includes a protective cover 21, which is located at the front side of the refrigerator body 1 and is used to block the front side of the refrigerator body 1 to prevent foreign objects from damaging the parts in the refrigerator body 1. A sliding cavity 22 is provided in the middle of the inner side of the protective cover 21 to limit the sliding trajectory of the slider 23. A slider 23 is slidably connected to one end of the inner side of the sliding cavity 22 to drive the bottom of the first support plate 26 to slide toward one end. A screw 24 is slidably connected to the middle of the inner side of the slider 23 to drive the slider 23 to slide. The block 23 slides to one end, and both the front and rear sides of the slider 23 are rotatably connected to a first support plate 26, and the middle part of one side of the first support plate 26 is rotatably connected to a second support plate 27. The first support plate 26 and the second support plate 27 cooperate with each other to facilitate the lifting of the refrigerator body 1 and separation from the ground. The top of one end of the second support plate 27 is rotatably connected to a connecting protective frame plate 28 for positioning the tops of the first support plate 26 and the second support plate 27, and the middle part of the top of the connecting protective frame plate 28 is rotatably connected to a turntable 29 for positioning the refrigerator body. The middle part of the bottom end of the body 1 is sucked, and a limiting slide groove 25 is opened on the inner wall of the front and rear sides of the connecting protection frame plate 28 and one end of the sliding cavity 22, which is used to limit the rotation trajectory of the first support plate and the second support plate. The top of the other end of the first support plate 26 is rotatably connected to the other end of the inner side of the connecting protection frame plate 28, and the bottom of the other end of the second support plate 27 is rotatably connected to the other end of the inner side of the sliding cavity 22. The top of one end of the second support plate 27 is slidably connected to the limiting slide groove 25 opened on the connecting protection frame plate 28. The first support plate 2 6 The bottom of one end is slidably connected with the limiting slide groove 25 provided on the inner side of the sliding cavity 22, and a docking slot is provided on the inner side of one end of the screw rod 24 for mounting and docking the motor. Three mounting blocks are evenly distributed on the upper and lower ends of the protective cover plate 21 for mounting and fixing the protective cover plate 21 to the refrigerator body 1. A supporting leg is fixedly connected to the diagonal part of the bottom end of the refrigerator body 1 for supporting the refrigerator body 1, and a groove is provided at the bottom of one side of the supporting leg for limiting the sliding trajectory of the protective cover plate 21.

[0024] See also Figure 2 and Figure 3 A liquid filling tank 3 is provided at the bottom of one end of the inner side of the refrigerator body 1, a first liquid delivery pipe 4 is provided at the top of one end of the rear side of the liquid filling tank 3, one end of the first liquid delivery pipe 4 is fixedly connected to an expansion valve 5, and the top of one end of the expansion valve 5 is fixedly connected to a second liquid delivery pipe 6, and a color-changing paper tape 210 is provided above one end of the first liquid delivery pipe 4, and one end of the color-changing paper tape 210 is fixedly connected to a color-changing paper ring 211 for detecting whether there is liquid leakage in the liquid delivery pipe.

[0025] Working principle: During maintenance, the protective cover 21 is removed from the front side of the refrigerator body 1, and then the protective cover 21 is turned over with the side facing the inside of the refrigerator body 1, facing the bottom of the refrigerator body 1, and then the protective cover 21 is pushed to make the protective cover 21 slide along the groove to one end. When the turntable 29 provided in the middle of the protective cover 21 slides to the middle of the bottom end of the refrigerator body 1, the motor is connected to one end of the screw 24, and the motor is started. The motor drives the screw 24 connected to the output end to rotate, and the rotating screw 24 drives the slider 23 connected to the outer sliding side to move along the The sliding cavity 22 slides toward one end, and the sliding block 23 slides toward one end, which pushes the bottom end of the first support plate 26 that is rotatably connected on both the front and rear sides to slide toward one end, so that the middle part of the first support plate 26 rotates around the rotation axis of the middle part, thereby driving the other end of the first support plate 26 to rotate upward, and the first support plate 26 that rotates upward drives the top of the second support plate 27 that is rotatably connected in the middle to rotate upward synchronously. When the positions of one end of the first support plate 26 and the second support plate 27 remain unchanged, the top of the first support plate 26 and the second support plate 27 rotate upward, which drives the connected protection frame plate 28 to rotate upward. When the upwardly moved connecting protection frame plate 28 is separated from the protective cover plate 21, the upwardly moved connecting protection frame plate 28 will drive the rotating disk 29 connected to the top middle part to be stuck on the outer surface of the middle part of the bottom end of the refrigerator body 1, and the bottom end of the refrigerator body 1 is sucked while driving the refrigerator body 1 to rise. When the upwardly moved connecting protection frame plate 28 drives the refrigerator body 1 to rise to a suitable position through the rotating disk 29, the rotation of the screw rod 24 is stopped. During maintenance, the staff only needs to manually rotate the refrigerator body 1, and the rotating disk 29 will drive the refrigerator body 1 of the suction hoop to slowly rotate 360 ​​degrees, thereby performing three-dimensional suction on the refrigerator body 1. Rotate 160 degrees for maintenance. If the first liquid delivery pipe 4 leaks liquid, the leaked liquid will penetrate into the corresponding position of the color-changing paper tape 210. The color of the color-changing paper tape 210 will change when it comes into contact with the liquid. When the staff sees that an area on the outer surface of the color-changing paper tape 210 has changed to other colors, they only need to inspect the first liquid delivery pipe 4 and the second liquid delivery pipe 6 in the area where the color-changing paper tape 210 and the color-changing paper ring 211 change color. This helps save time for liquid delivery pipe maintenance. Contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
