Description

Technical Field

[0001] This utility model relates to the field of vending machines, and in particular to an automatic lifting door. Background Technology

[0002] Most vending machines on the market (such as beverage dispensers and popcorn machines) have a dispensing slot on the cabinet door. Customers take their purchases from the dispensing slot. To ensure the safety and privacy of the entire vending machine, some vending machines also have an automatic lifting door on the back of the dispensing slot. The automatic lifting door is connected to the back of the cabinet door through a guide slide structure. For lifting doors with a guide slide structure, there is a certain gap between the lifting door body and the cabinet door panel, resulting in poor sealing of the dispensing slot. For lifting doors with a sliding track structure, the lifting door body comes into contact with the sliding track and rubs against it. Over time, the lifting door body and the sliding track will wear down. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide an automatic lifting door. This utility model adopts the following technical solution:

[0004] This utility model provides an automatic lifting door, including a door body. Vertically arranged sliding grooves are provided on both sides of the door body. Rollers are provided on both sides of the door body, and the rollers roll in cooperation with the sliding grooves. A settling groove is provided on the side of the sliding groove corresponding to the rollers, and the settling groove smoothly transitions to the sliding groove. A lifting frame is provided on the back of the door body. An elastic element is provided between the door body and the lifting frame, with one end of the elastic element abutting against the door body and the other end abutting against the lifting frame. The two sides of the lifting frame are slidably connected to slide rails, which are arranged side-by-side with the sliding grooves. Multiple guide sleeves are provided on the lifting frame, and the guide sleeves are vertically fixed to the lifting frame. A guide rod is provided in each guide sleeve, and one end of the guide rod is fixed to the door body.

[0005] Preferably, the elastic element is a spring, and each guide rod is fitted with the spring.

[0006] Preferably, it includes a pressure strip, which is fixed to the back of the cabinet door panel, and the strip-shaped gap between the pressure strip and the cabinet door panel is the sliding groove, and the settling groove is provided on the cabinet door panel.

[0007] Preferably, the lower part of the door is connected to a lifting drive device.

[0008] Preferably, the lifting drive device includes a lead screw, a push block is threadedly connected to the lead screw, the push block is fixed to the lifting frame, and a drive motor is provided at the lower end of the lead screw.

[0009] Preferably, the lifting drive device is an electric cylinder.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This invention improves the sealing of the dispensing slot on a vending machine by setting a settling groove in the slide rail, allowing the roller to be embedded after rolling into the settling groove. At the same time, the roller rolling during the lifting and lowering of the door avoids wear and tear on the lifting door and slide rail. Attached Figure Description

[0022] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4As shown, this embodiment discloses an automatic lifting door, including a door body 1. Vertically arranged sliding grooves 2 are provided on both sides of the door body 1. Rollers 3 are provided on both sides of the door body 1. The rollers 3 roll with the sliding grooves 2. A settling groove 4 is provided on the side of the sliding groove 2 corresponding to the rollers 3. The settling groove 4 and the sliding groove 2 are smoothly connected. A lifting frame 5 is provided on the back of the door body 1. An elastic member 6 is provided between the door body 1 and the lifting frame 5. One end of the elastic member 6 abuts against the door body 1, and the other end abuts against the lifting frame 5. The two sides of the lifting frame 5 are slidably connected to the slide rails 7. The slide rails 7 and the sliding grooves 2 are arranged side by side. Multiple guide sleeves 8 are provided on the lifting frame 5. The guide sleeves 8 are vertically fixed to the lifting frame 5. A guide rod 9 is provided in the guide sleeve 8. The guide rod 9 is slidably connected to the guide sleeve 8. One end of the guide rod 9 is fixed to the door body 1.

[0024] Taking the retrieval of goods from an automatic vending machine as an example: (1) After the goods are retrieved, the lifting door rises to close the retrieval opening 13. The door body 1 moves upward in the slide 2 through the rollers 3 on both sides. When the rollers 3 roll into the settling groove 4 in the slide 2, the door body 1 moves under the action of the elastic element 6 on the back. With the vending machine cabinet door as a reference, the door body 1 moves outward as a whole and then fits against the back of the vending machine cabinet door, thus achieving complete closure of the retrieval opening. (2) When preparing to retrieve goods, the lifting door descends to open the retrieval opening 13. The rollers 3 roll out from the settling groove 4 and then roll into the slide 2. With the vending machine cabinet door as a reference, the door body 1 moves inward as a whole and then moves slightly away from the back of the vending machine cabinet door (a certain gap is created between the front of the door body 1 and the back of the vending machine cabinet door). The door body 1 moves downward in the slide 2 through the rollers 3 on both sides, thus achieving the opening of the retrieval opening.

[0025] This utility model takes an automatic vending machine as an example, such as... Figures 5 to 7 As shown, the settling trough 4 is set on the cabinet door panel 11 of the automatic receiving machine by stamping. The settling trough 4 protrudes outward from the cabinet door panel 11. There are two settling troughs 4, which are arranged on both sides of the picking port 13 (the picking port 13 is set on the cabinet door panel 11). Similarly, there are also two rollers 3 that cooperate with the settling trough 4.

[0026] On the back of the cabinet door panel 11, pressure strips 10 are arranged on both sides of the loading port 13. The pressure strips 10 are fixed on the cabinet door panel 11, and the strip-shaped gap between the pressure strips 10 and the cabinet door panel 11 constitutes the sliding groove 2 in this technical solution.

[0027] In this embodiment, the elastic element 6 is a spring, and each guide rod 9 is fitted with a spring. Four guide sleeves 8 are arranged on the lifting frame 5, and each of the four guide rods 9 that cooperate with the guide sleeves 8 is fitted with a spring.

[0028] In this embodiment, the lower part of the door 1 is connected to the lifting drive device 12. For example... Figure 8As shown, the lifting drive device 12 includes a lead screw 1201, a push block 1202 threadedly connected to the lead screw 1201, the push block 1202 being fixed to the lifting frame 5, and a drive motor 1203 disposed at the lower end of the lead screw 1201. The drive motor 1203 is mounted and fixed on the back of the cabinet door panel 11. In addition to this embodiment, the lifting drive device 12 can also directly use an electric cylinder.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
