DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiment is one embodiment of the present application, not all embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0025] Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which this application belongs.
[0026] The present embodiment provides a freezing box pushing device 10 , which includes a bottom plate 100 , a top plate 300 , a supporting plate 500 and a box pushing plate 600 . Figure 1 is a stereoscopic diagram of a freezing box pushing device 10 according to some embodiments of the present application, Figure 2 yes Figure 1 Another view of the structure shown.
[0027] The bottom plate 100 is rotatably connected to the lower end of the screw 200. The top plate 300 is rotatably connected to the upper end of the screw 200. The top plate 300 is also equipped with a driving motor 400, which is connected to the upper end of the screw 200 and is used to drive the screw 200 to rotate. The supporting plate 500 is installed at the middle of the screw 200, and the supporting plate 500 is configured to move up and down when the screw 200 rotates. The supporting plate 500 is used to carry the freezing rack, and the freezing rack defines a plurality of placement cavities arranged in the up and down direction. The front part of the placement cavity has a front opening, and the placement cavity is used to place the freezing box, and the placement cavity at the top has a rear opening. The box pusher plate 600 is movably installed on the top plate 300, and the box pusher plate 600 is rotatably connected to one end of the telescopic rod 530, and the other end of the telescopic rod 530 is rotatably connected to the supporting plate 500. When the supporting plate 500 drives the freezing rack to move downward until the lower end of the topmost placement cavity is flush with the box pushing plate 600, the telescopic rod 530 is extended to its longest position. As the supporting plate 500 drives the freezing rack to continue to move downward, the telescopic rod 530 drives the box pushing plate 600 to move forward, so that the box pushing plate 600 pushes the freezing box in the topmost placement cavity through the rear opening and moves it out of the placement cavity through the front opening.
[0028] Figure 3 yes Figure 1 A side view of the structure is shown in a first state. Figure 4 yes Figure 1 A side view of the structure is shown in a second condition. Figure 5 yes Figure 1 A side view of the structure shown in a third state.
[0029] like Figures 3 to 5 As shown, when the support plate 500 drives the freezing rack to move downward until the lower end of the placement cavity at the top is flush with the box pushing plate 600, the freezing box pushing device 10 is in the first state (at this time, the telescopic rod 530 is extended and the box pushing plate 600 does not move). After the support plate 500 drives the freezing rack to move downward until the lower end of the placement cavity at the top is flush with the box pushing plate 600, the freezing box pushing device 10 will first be in the second state (at this time, the telescopic rod 530 has been extended to the longest and cannot be extended, and the box pushing plate 600 moves forward), and then in the third state (at this time, the telescopic rod 530 has been extended to the longest and cannot be extended, and the box pushing plate 600 has moved forward to the front end and cannot move forward any further).
[0030] This freezing box pushing device 10, through the arrangement of the supporting plate 500, the box pushing plate 600 and the telescopic plate, enables a driving motor 400 to simultaneously realize the up and down movement of the freezing rack and move the freezing box to the outside of the placement chamber, and has a simple structure and low cost.

[0032] In some embodiments, an elastic member (not shown in the figure) is provided in the guide groove, and the elastic member is connected to the front groove wall of the guide groove and the front end of the box pushing plate 600. The elastic member is used to apply an elastic force toward the rear to the box pushing plate 600, so that when the supporting plate 500 drives the freezing rack to move upward, the backward movement of the box pushing plate 600 is earlier than the retraction action of the telescopic rod 530.
[0033] Thereby, it is ensured that when the freezing shelf moves upward, the entire freezing box pushing device 10 will not get stuck.

Thus, the movement of the support plate 500 can be guided. Specifically, there can be a plurality of guide rods 800.
[0036] In some embodiments, the supporting plate 500 is provided with a transmission hole, a transmission sleeve 510 is fixed in the transmission hole, the transmission sleeve 510 is provided with threads, and the supporting plate 500 is moved up and down through the transmission sleeve 510 .

Thus, the movement of the support plate 500 can be guided. Specifically, there can be multiple guide plates 900.
[0038] In some embodiments, at least one limiting protrusion 520 for limiting the position of the freezing rack is disposed on the upper end of the supporting plate 500, thereby ensuring the limiting effect of the freezing rack.
[0039] In some embodiments, a first mounting seat (not shown in the figure) is provided at the rear portion of the push box plate 600, and the first mounting seat defines a first mounting groove, and a first rotating shaft is installed in the first mounting groove. A first opening is opened at one end of the telescopic rod 530 for the first rotating shaft to pass through, so that the push box plate 600 is rotatably connected to one end of the telescopic rod 530.
[0040] In some embodiments, a second mounting seat (not shown in the figure) is provided at the rear portion of the support plate 500, and the second mounting seat defines a second mounting groove, and a second rotating shaft is installed in the second mounting groove. The other end of the telescopic rod 530 is provided with a second opening for the second rotating shaft to pass through, so that the support plate 500 is rotatably connected to the other end of the telescopic rod 530.
[0041] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.
