[0009] Furthermore, a guide rod is fixedly connected to the surface of the card plate, and one end of the guide rod has an arc surface that slides through the surface of the connecting frame. The effect achieved by the above components is that when the position of the card plate is moved, the guide rod can be used for protection to prevent the position of the card plate from shifting.

[0010] Furthermore, an auxiliary device is provided on the inner wall surface of the heating chamber. This auxiliary device includes two support plates and a support frame. The bottom ends of the two support plates are fixedly connected to the bottom surface of the inner wall of the heating chamber. A common drive rod is rotatably connected to one end of each support plate, with threads of opposite directions at both ends of the arc-shaped surface of the drive rod. A movable plate is threaded through both ends of the drive rod. A docking frame is fixedly connected to one side of the movable plate. The docking frame has a U-shaped cross-section. A bottom frame is fixedly connected to the bottom end of the support frame. Side holes are provided on both sides of the bottom frame. A side block is fixedly connected to the inner wall surface of the docking frame. The side block has an arc-shaped cross-section, and its surface inserts into the inner wall of the side hole. The effect achieved by the above components is that during the product heating process, the auxiliary device inside the heating chamber can be used for operation. The product is placed and heated using the support frame, and the two connecting frames can be used to separate and limit the support frame, facilitating replacement after prolonged use.

[0011] Furthermore, the surfaces of the two movable plates are slidably connected by the same auxiliary rod, the two ends of which are fixedly connected to the surface of the support plate. The effect achieved by the above components is that the auxiliary rod can protect the two connecting frames from movement.

[0012] Furthermore, a guide plate is fixedly connected to the upper surface of the docking frame, and the guide plate has an arc-shaped cross-section. The effect achieved by the above components is that the arc-shaped guide plate facilitates the insertion and guiding operation of the bottom frame fixed to the lower surface of the support frame.

[0014] This utility model provides an unmanned vending machine with integrated freezing and heating. By operating the adjustment device, the internal space of the refrigeration chamber can be controlled. By moving and adjusting several support plates along the slide rail, the distance between two support plates can be effectively adjusted and fixed. At the same time, the position of the support plates can be effectively and conveniently positioned by the locking plates between the sliding frames and the toothed plates set between the slide rails.

[0015] By operating the auxiliary device, the position of the support frame inside the heating chamber is limited. During the heating process, the support frame can be used to support and place the product, preventing the heated product from sticking to the bottom of the inner wall of the heating chamber. At the same time, it makes the heating chamber cleaner and helps to improve the uniformity of heat transfer, so that all parts of the product can be heated more evenly. Attached Figure Description

Then, pull the support plate 405 to slide along the slide rail 401 until it reaches the designated position. Afterward, release the fixing ring 410 and the adjusting rod 409. Simultaneously, the locking plate 411, with the help of the squeezing force generated by the spring 413, re-engages with the toothed plate 402 fixed on one side of the slide rail 401. At this point, the position of the entire support plate 405 will be adjusted. It will be fixed. During this process, it can also be connected to the limiting plate 407 through the limiting groove 406 on the surface of the bearing plate 405, so that the limiting plate 407 can be used to provide spacing protection. When heating the product that has been taken out, it can be assisted by the heating cavity 6 at the bottom of the cabinet 1. The product needs to be placed in the bearing frame in the auxiliary device 5. After long-term use, the bearing frame needs to be replaced and the limiting position needs to be changed. At this time, the drive rod 507 is rotated so that the drive rod 507 drives the docking frame 504 at both ends to move and adjust. At the same time, the replaced bearing frame is docked and limited by the bottom frame 502 fixed on the lower surface until the side block 510 fixed on the inner wall surface of the docking frame 504 is inserted and fixed with the side holes 503 on both sides of the bottom frame 502.
