The distances between the plurality of adjustment slots 31 gradually close from top to bottom, and an adjustment column 32 is slidably connected to each of the adjustment slots 31.

[0033] An adjusting plate 33 is fixedly mounted on one end of the adjusting column 32 close to the back plate 2. The adjusting plate 33 is horizontally slidably connected to the back plate 2. A pressing plate 4 is fixedly mounted on the bottom end of the adjusting plate 33.

[0034] A through hole is provided in the middle of the top wall of the support frame 12, in which the outer peripheral surface of the bearing 52 is fixedly installed, and the inner peripheral surface of the bearing 52 is fixedly installed with the rotating shaft 51, and the bottom end of the rotating shaft 51 is fixedly connected to the back plate 2 through the telescopic cylinder B24.

[0035] Optionally, in the above technical solution, a telescopic cylinder A21 is fixedly installed on one side of the back panel 2, the piston end of the telescopic cylinder A21 extends downward, and one end of the horizontal plate 22 is fixedly installed on the end, and the other end of the horizontal plate 22 is fixedly installed on the lifting plate 3.

[0036] Optionally, in the above technical solution, sliders A30 are fixedly installed on both sides of the lifting plate 3 close to the back plate 2, two slide rails A20 are fixedly installed on the back plate 2, and the sliders A30 are slidably connected to the slide rails A20 on the same side.

[0037] Optionally, in the above technical solution, a slide rail B23 is fixedly installed between the two slide rails A20, and a slider B34 is fixedly installed on the side of the adjustment plate 33 close to the back plate 2, and the sliders B34 are slidably connected to the slide rail B23.

[0038] Optionally, in the above technical solution, a rotating plate 53 with a square structure is fixedly installed on the top of the rotating shaft 51, and four rotating grooves 54 are opened on the rotating plate 53. Two adjacent rotating grooves 54 are perpendicular to each other, and an arc groove 55 is opened on the rotating plate 53 and located between two adjacent rotating grooves 54.

[0039] Optionally, in the above technical solution, a driving motor 61 is fixedly mounted on the top wall of the support frame 12 , one end of a connecting rod 62 is fixedly mounted on the output shaft of the driving motor 61 , and the other end of the connecting rod 62 is fixedly mounted on a pin 63 that is slidably connected to the rotating groove 54 .

[0040] The distances between the upper ends of adjacent adjustment slots 31 are equal, the distances between the lower ends of adjacent adjustment slots 31 are equal, the middle adjustment slot 31 is vertically arranged, and the farther the adjustment slot 31 is from the middle adjustment slot 31, the greater its inclination angle.

[0041] Specifically, the placement component includes an adjustment unit and a fixing unit;

[0042] The adjustment unit includes a bidirectional screw rod 71 that is horizontally rotatably connected to the stabilizing chamber 11, and a transmission block 72 that is symmetrically mounted on the bidirectional screw rod 71. A sliding chamber 73 is defined in the top wall of the stabilizing chamber 11. A transmission plate 74 is fixedly mounted on the transmission block 72. The transmission plate 74 is slidably connected to the sliding chamber 73. A rocker 70 is fixedly mounted on one end of the bidirectional screw rod 71. The rocker 70 extends through the side wall of the stabilizing chamber 11 and is rotatably connected thereto.

[0043] The fixing unit includes a horizontal plate 81 fixedly mounted on the transmission plate 74 , a fixing plate 82 fixedly mounted on the horizontal plate 81 , a screw rod 83 threadedly passed through the fixing plate 82 , and a pressure plate 84 fixedly mounted on the bottom end of the screw rod 83 .

[0044] Working principle:

[0045] During use, the rocker 70 is rotated to rotate the bidirectional screw rod 71 clockwise, driving the transmission blocks 72 to move closer to each other on the bidirectional screw rod 71, thereby moving the transmission plates 74 closer to each other along the sliding cavity 73. The refrigerator partition is placed on the two horizontal plates 81 so that the refrigerator partition corresponds to the middle position of the stabilizing cavity 11. By rotating the screw rod 83 clockwise, the pressing plate 84 presses and fixes the two sides of the refrigerator partition.

[0046] According to the size of the refrigerator partition, the distance between the multiple pressing plates 4 on the back plate 2 is adjusted so that the pressing plates 4 are evenly distributed on the refrigerator partition. The telescopic cylinder B24 is activated to move its movable end downward to drive the back plate 2 downward, and the pressing plates 4 press the refrigerator partition.

[0047] In the initial state, the long side of the pressing plate 4 is perpendicular to the long side of the stabilizing cavity 11, that is, the pressing plate 4 presses down equidistantly along the length direction of the refrigerator partition. When it is necessary to press down equidistantly along the width direction of the refrigerator partition, the pressing plate 4 needs to be rotated 90 degrees;

[0048] The rotation of the pressing plate 4 is adjusted as follows: the driving motor 61 is started to drive the detent pin 63 through the connecting rod 62, and the detent pin 63 rotates 360 degrees along the center line of the output shaft of the driving motor 61, so that the detent pin 63 slides into a rotation groove 54 and then slides out of the rotation groove 54. At this time, the driving motor 61 is stopped, which will drive the rotating plate 53 to rotate 90 degrees, and the back plate 2 is driven to rotate 90 degrees as a whole through the rotating shaft 51 fixed thereto. This rotation adjustment method adopts a 90-degree intermittent rotating groove wheel mechanism;

[0049] The distance between the pressing plates 4 is adjusted as follows: the telescopic cylinder A21 is started so that its movable end drives the lifting plate 3 through the horizontal plate 22, and moves up (or down) along the slide rail A20 through the slider A30. When the lifting plate 3 moves up (or down), the adjusting column 32 drives the adjusting plate 33, and moves closer (or farther) from each other along the slide rail B23 through the slider B34, so that the distance between the multiple pressing plates 4 is synchronously reduced (or increased); when it is necessary to press down the middle part of the refrigerator partition, the pressing plates 4 are adjusted to a close contact state, that is, the lifting plate 3 is located at the uppermost end, and the adjusting column 32 is in contact with the inner bottom wall of the adjusting groove 31.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
