Description

Technical Field

[0001] The utility model relates to the technical field of vending cabinets, in particular to a cabinet structure of an automatic vending cabinet. Background Art

[0002] A vending machine is a machine that automatically dispenses items based on the amount of money inserted. Vending machines are a common form of commercial automation, operating without time or location restrictions, saving labor and facilitating transactions. They represent a new form of retail, often referred to as 24-hour mini-supermarkets. Common vending machines fall into four categories: beverage vending machines, food vending machines, combination vending machines, and cosmetics vending machines.

[0003] At present, electronic locks are generally used in vending machines. After scanning a code, swiping a card or performing facial recognition in the POS machine, the electronic lock will open the cabinet door, and then the required food or beverage can be purchased. However, when there is a power outage or the electronic lock malfunctions, this function cannot be used, resulting in a reduction in the effectiveness of the electronic lock. Moreover, the electronic lock of the existing vending cabinet is installed at the top or at the bottom. When installed at the top, the user can open the cabinet door at the bottom under the action of external force, which reduces its safety performance. Based on this, we propose a cabinet structure for a vending cabinet. Utility Model Content

By locating the electric lock mechanism 3 in the middle of the cabinet body 1, the top or bottom of the cabinet door 2 can be effectively prevented from being opened by external force, thereby further improving the safety performance of the vending machine cabinet.

[0032] The electric lock mechanism 3 includes an electronic lock 5, one end of which is provided with a mechanical part 6, and the other end is provided with a locking part 7. When the mechanical part 6 moves downward, it can drive the locking part 7 to rotate along the upper circle; the electronic lock 5 of this application adopts an electronic lock 5 with model J-R4-EM-87 produced by Southco Asia Co., Ltd., which has a mechanical part 6 and a locking part 7, and can be matched with the mechanical lock mechanism 4.

[0033] The mechanical lock mechanism 4 includes a housing 8, a T-lock 9 and a connecting plate 10. The housing 8 is fixed to the cabinet 1, and a T-lock 9 is also installed on the housing 8. The moving end of the T-lock 9 is fixedly connected to the connecting plate 10 by a nut. The connecting plate 10 is provided with a connecting groove 11. The connecting plate 10 is connected to a steel wire rope 12 through the connecting groove 11. The other end of the steel wire rope 12 is connected to the housing 8 and connected to the mechanical part 6. A spring 13 is connected between the connecting plate 10 and the housing 8. In this embodiment, when the T-lock 9 rotates, it can drive the connecting plate 10 in the mechanical lock mechanism 4 to rotate, thereby driving the steel wire rope 12 to pull to the left. The steel wire rope 12 located in the vertical direction is in a downward pulled state. When the other end of the steel wire rope 12 is connected to the mechanical part 6 of the electronic lock 5, the mechanical part 6 of the electronic lock 5 can be pulled by the steel wire rope 12, thereby rotating to open the locking part 7 of the electronic lock 5, thereby using this mechanical lock method to open the cabinet door 2 when the power is off or when the electronic lock 5 fails.

The connecting shell 14 is fixedly connected to the cabinet body 1, and the electronic lock 5 is fixedly installed inside the connecting shell 14. The fastener 15 is fixedly connected to the cabinet door 2. A lock column 16 is provided on the fastener 15. An insertion cavity is formed between the locking portion 7 and the electronic lock 5, and the lock column 16 is inserted into the insertion cavity. It can be understood that when the locking portion 7 is rotated upward to open, the locking portion 7 will open the insertion cavity, so that when the cabinet door 2 is opened, the fastener 15 and the lock column 16 are pulled out of the insertion cavity, realizing the process of mechanical unlocking. In addition, when the electronic lock 5 itself is energized, it also drives the mechanical portion 6 to move downward, thereby driving the locking portion 7 to rotate upward to open.

[0035] As a preferred embodiment; the fastener 15 also includes a mounting block 17, the lock column 16 is fixedly connected to one end of the mounting block 17, and the other end of the mounting block 17 is provided with a first adjustment hole 18, the mounting block 17 is fixed to the cabinet door 2 by screws, the first adjustment hole 18 is a strip hole structure, and the first adjustment hole 18 is provided with several; it can be understood that the purpose of providing the first adjustment hole 18 is to be able to adjust the position of the mounting block 17, and then adjust the position of the lock column 16, so that the lock column 16 is more adapted to the position of the insertion cavity.

[0036] As a preferred embodiment, the connecting plate 10 is provided with a plurality of first connecting holes 19, and the housing 8 is provided with a plurality of second connecting holes 20. Hook-shaped connecting wires extend from both ends of the spring 13, with one end of the spring 13 being hooked to the first connecting hole 19 via the hook-shaped connecting wire, and the other end of the spring 13 being hooked to the second connecting hole 20 via the hook-shaped connecting wire. The spring 13 is arranged at an angle, and both the first connecting hole 19 and the second connecting hole 20 are circular hole structures. The provision of a plurality of first connecting holes 19 and second connecting holes 20 allows the spring 13 to be hooked to different hole positions, facilitating adjustment of the spring 13's inclination and, consequently, its elastic force. Furthermore, hook-shaped connecting wires extend from both ends of the spring 13, facilitating hooking the spring 13 and its attachment to first connecting holes 19 and second connecting holes 20 at different positions. In addition, the spring 13 is tilted to increase the torque and improve the reset effect. Secondly, it can match the installation position of the connecting plate 10 so that the connecting plate 10 can effectively pull down the wire rope 12 when rotating.

[0037] As a preferred embodiment, a first circular stopper ball 21 is provided at one end of the steel wire rope 12 located in the connecting groove 11, and a second circular stopper ball 22 is provided at the other end. The first circular stopper ball 21 is engaged in the connecting groove 11, and the second circular stopper ball 22 is engaged in the mechanical part 6. The provision of the first circular stopper ball 21 and the second circular stopper ball 22 allows for a stopper to be formed at both ends of the steel wire rope 12, facilitating the pulling and resetting of the mechanical part 6.

[0038] As a preferred embodiment, a circular insertion hole 23 is provided at one end of the connecting groove 11 away from the first connecting hole 19. The diameter of the circular insertion hole 23 is larger than the diameter of the first circular limiting ball 21. By providing the circular insertion hole 23, the first circular limiting ball 21 can enter the connecting groove 11 through the hole. The connecting groove 11 is strip-shaped, and the gap width of the strip-shaped connecting groove 11 is smaller than the diameter of the circular insertion hole 23.

[0039] As a preferred embodiment, the steel wire rope 12 is sheathed with a jacket 24. The end of the jacket 24, which is closest to the first circular stopper ball 21, is fixedly connected to an adjustment sleeve 25. One end of the adjustment sleeve 25 is provided with an external thread 26. The jacket 24 is made of rubber. The adjustment sleeve 25 is provided to adjust the distance between the jacket 24 and the connecting plate 10, allowing the steel wire rope 12 to expand and contract (within the jacket 24), thereby adjusting the position of the steel wire rope 12 on the connecting groove 11.

[0040] As a preferred embodiment, the housing 8 is further provided with a notch, into which the adjusting sleeve 25 extends and is threadedly connected with a first nut 27 and a second nut 28. The first nut 27 and the second nut 28 respectively abut against the inner and outer sides of the housing 8. Mounting the adjusting sleeve 25 in the notch saves installation space, and the external threads 26 on the adjusting sleeve 25 precisely connect with the first and second nut threads 27 and 28. After adjusting the position, the adjusting sleeve 25 can be fixed to the housing 8, forming a better adjustable installation structure.

[0041] As a preferred embodiment, the housing 8 is provided with a first bent edge 29 and a second bent edge 30, each of which is provided with a screw hole, and screws are installed in each of the screw holes. It can be understood that the provision of the first bent edge 29 and the second bent edge 30 facilitates the installation of the housing 8 on the door edge of the cabinet 1, and the housing 8 is fastened at two locations, which provides a better fixing effect.

[0042] As a preferred embodiment; the side of the housing 8 close to the T-lock 9 is provided with second adjustment holes 31 at upper and lower ends, and the T-lock 9 is mounted on the housing 8 by means of a screw and a nut. It can be understood that the second adjustment hole 31 is an elliptical structure, and the screw can be adjusted up and down inside the second adjustment hole 31, thereby adjusting the position of the T-lock 9 on the housing 8. After the T-lock 9 is connected to the screw, the screw is extended into the second adjustment hole 31 and finally fastened by a nut (what is fixed is the housing of the T-lock 9, and a rotating handle and a rotating mechanism are also provided on the T-lock 9. The rotating handle and the rotating mechanism are both mounted on the housing, and the rotating mechanism corresponds to the moving end of this article).

[0043] In this application, the T-lock 9 adopts a model MK210 T-lock 9 produced by Xiamen Meike Security Technology Co., Ltd. The T-lock 9 includes a lock body and a lock cylinder. The lock cylinder is installed inside the lock body, and the locking piece on the lock cylinder is locked in the limit hole of the lock body. When the lock cylinder is opened and rotated with a key, the locking piece on the lock cylinder will leave the limit hole of the lock body, at which time the lock body can be rotated. When the lock body rotates, it can drive its moving end to rotate, and finally drive the connecting plate 10 to rotate. Therefore, in this T-lock 9, the function of the lock cylinder is to lock the lock body so that it cannot rotate unless the limit is released. In addition, the lock cylinder can also be replaced according to the user's needs. That is, before sale, the original lock cylinder is disassembled and a limit pin is installed. The limit pin can lock the limit hole of the lock body. After the user obtains the unlocking device, the limit pin can be removed and a new lock cylinder can be installed. The advantage of this is that the security protection level can be greatly improved (replacing the user's own lock cylinder).

[0044] The working principle of the present invention is as follows: when using the device, the extended end of the steel wire rope 12 is first connected to the mechanical part 6 of the electronic lock 5. When the steel wire rope 12 is pulled downward, the mechanical part 6 on the electronic lock 5 can be pulled, and then the locking part 7 of the electronic lock 5 can be rotated to open, so that the locking part 7 of the electronic lock 5 is separated from the lock column 16 of the cabinet door 2, and then the cabinet door 2 can be opened;

[0045] During operation, first insert the key and turn the T-lock 9. The T-lock 9 will drive the connecting plate 10 to rotate, and then drive the wire rope 12 to pull left. The wire rope 12 in the vertical direction is in a downward pull state, and the spring 13 generates elastic force when rotating. When the external force is lost (at the T-lock 9), the T-lock 9 can be reset by rotating it through the spring 13, making it more convenient to use and having a better effect.

[0046] It should be pointed out that the main problem with the existing technology is that when there is a power outage or the electronic lock of the existing vending machine fails, the electronic function cannot be used, resulting in reduced effectiveness of the electronic lock (or requiring professional maintenance personnel to open the cabinet door, which is extremely inconvenient);

[0047] Therefore, after the improvement of the present application, by providing a mechanical lock mechanism 4, when the T-lock 9 rotates, it can drive the connecting plate 10 in the mechanical lock mechanism 4 to rotate, and then drive the wire rope 12 to be pulled to the left, and the wire rope 12 located in the vertical direction is in a downward pulled state. When the other end of the wire rope 12 is connected to the mechanical part 6 of the electronic lock 5, the mechanical part 6 of the electronic lock 5 can be pulled by the wire rope 12, and then the locking part 7 of the electronic lock 5 can be rotated to open, so that the cabinet door 2 can be opened by this mechanical lock when the power is off or when the electronic lock 5 fails. Moreover, the method of opening the cabinet door 2 by using this mechanical lock is also relatively simple, its structure is compact, and it can be reset in time under the action of the spring 13. The external force output is relatively small. It can be used as a backup unlocking, which can greatly improve the use effect of the automatic vending machine.

[0048] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
