Description

Technical Field

[0001] The invention relates to a vending device with anti-theft function. Background Art

[0002] At present, there is a rotating vending device on the market, the principle of which is to use a rotating shelf that can rotate in both directions; when rotating in the forward direction, the goods can be delivered to the delivery port, and when rotating in the reverse direction, the cargo door can be opened. In order to achieve the above functions, under the existing technical level, the cargo door and the cargo box cannot be rigidly connected, and can only be connected by elastic elements. When elastic elements are used, the door can be easily pushed open by people's hands or tools, and the goods can be stolen. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a vending device with an anti-theft function, comprising a cargo box, a cargo door, a shelf, a pushing block, and an anti-theft lock; the cargo box is provided with a delivery port; the cargo door is used to close the delivery port; the shelf is arranged in the cargo box and can rotate in both directions relative to the delivery port; the pushing block is arranged between the shelf and the cargo door, and can be used to connect the shelf and the cargo door when the shelf rotates; the anti-theft lock is arranged on the cargo box, and when the cargo door closes the delivery port, the anti-theft lock can be buckled on the cargo door to lock the cargo door;

[0004] Among them, when the shelf rotates forward, the pushing block and the anti-theft lock buckle both move relative to the shelf or the cargo door so that the shelf avoids the cargo door; when the shelf rotates reversely, a force is applied to the anti-theft lock buckle to separate from the cargo door; when the anti-theft lock buckle separates from the cargo door and the shelf rotates reversely, the shelf applies a force to the cargo door to open the delivery port through the pushing block.

[0005] Furthermore, the vending device also includes a first return spring and a second return spring; when the cargo door is opened, the first return spring has a pre-tightening force that causes the cargo door to move in the direction of closing the delivery port; when the cargo door is disengaged from the anti-theft lock, the second return spring has a pre-tightening force that causes the anti-theft lock to buckle on the cargo door.

[0006] Furthermore, the pushing block is rotatably connected to the cargo door, a rotation limiting portion is provided on the cargo door, and a third return spring is provided between the pushing block and the cargo door. When the shelf rotates, the third return spring has a pre-tightening force that makes the pushing block be in a position where the shelf can touch. When the pushing block touches the shelf and the shelf rotates forward, the pushing block rotates relative to the cargo door to achieve the rotation of the shelf avoiding the cargo door. When the pushing block touches the shelf and the shelf rotates reversely, the pushing block can abut against the rotation limiting portion to achieve the contact between the shelf and the pushing block and the cargo door can be pushed open by the pushing block.

[0007] Furthermore, the anti-theft lock buckle is rotatably connected to the cargo box, and the anti-theft lock buckle includes a buckle end and a force-applying end; when the shelf rotates, the shelf can touch the force-applying end, and when the shelf touches the force-applying end and the shelf rotates forward, the anti-theft lock buckle rotates so that the shelf avoids the anti-theft lock buckle, and when the shelf touches the force-applying end and the shelf rotates reversely, the shelf can apply force to the force-applying end so that the buckle end rotates away from the cargo door.

[0008] Beneficial effects of the present invention:

[0009] The invention has a simple structure and can lock the cargo door tightly when no one is shopping through the anti-theft lock to prevent the cargo in the cargo box from being stolen. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See Figures 1 to 2 A vending device with an anti-theft function comprises a cargo box 1, a cargo door 2, a shelf 3, a push block 4, and an anti-theft lock buckle 5; the cargo box is provided with a delivery port 11; the cargo door 2 is used to close the delivery port 11; the shelf 3 is arranged in the cargo box 1 and can rotate in both directions relative to the delivery port 11; the push block 4 is arranged between the shelf 3 and the cargo door 2, and can be used to connect the shelf 3 and the cargo door 2 when the shelf 3 rotates; the anti-theft lock buckle 5 is arranged on the cargo box 1, and when the cargo door 2 closes the delivery port 11, the anti-theft lock buckle 5 is buckled on the cargo door 2 to lock the cargo door 2;

[0018] Among them, see Figure 3 and 4 When the shelf 3 rotates forward, the pushing block 4 and the anti-theft lock buckle 5 both move relative to the shelf 3 or the cargo door 2, so that the shelf 3 avoids the cargo door 2 and the anti-theft lock buckle 5 from rotating; when the shelf 3 rotates reversely, a force is applied to the anti-theft lock buckle 5 to separate from the cargo door 2; when the anti-theft lock buckle 5 separates from the cargo door 2 and the shelf 3 rotates reversely, the shelf 3 applies a force to the cargo door 2 through the pushing block 4 to open the delivery port 11.

[0019] When the vending device of the present invention is in use, the shelf 3 rotates forward to deliver the selected goods to a certain position (the position is called the door opening initial position). Figure 3 and 4 The push block 4 and the anti-theft lock 5 are both movable relative to the shelf 3 or the cargo door 2, so that the shelf 3 can avoid the rotation of the cargo door 2. When the shelf 3 rotates forward to the initial position of the door opening, Figure 5, start to open the cargo door 2. During the process of opening the cargo door 2, the shelf 3 rotates in the opposite direction. The shelf 3 first touches the anti-theft lock buckle 5 and applies a force to the anti-theft lock buckle 5 to separate from the cargo door 2, so that the anti-theft lock buckle 5 separates from the cargo door 2. After the anti-theft lock buckle 5 separates from the cargo door 2, the shelf 3 continues to rotate in the opposite direction. At this time, the shelf 3 applies a force to the cargo door 2 to open the delivery port 11 through the pushing block 4, so that the cargo door 2 opens the delivery port 11. When the cargo door 2 fully opens the delivery port 11, the selected goods can be taken out from the delivery port 11. In the present invention, the anti-theft lock buckle 5 provided above can enable the vending device to lock the cargo door 2 when no consumer is shopping, so as to prevent others from pushing open the cargo door 2 with their hands or other tools to steal the goods in the cargo box 1.

[0020] As a further solution of the present invention: Figure 2 The vending device further includes a first return spring 6 and a second return spring 7; when the cargo door 2 is opened, the first return spring 6 has a preload force that causes the cargo door 2 to move in a direction to close the delivery port 11; when the cargo door 2 is detached from the anti-theft lock 5, the second return spring 7 has a preload force that causes the anti-theft lock 5 to buckle on the cargo door 2. In this solution, the first return spring may be a compression type coil spring, and the second return spring may be a torsion spring.

[0021] In this solution, when the cargo door 2 needs to continue to close the delivery port 11 after opening the delivery port 11, the shelf 3 rotates forward. At this time, since the shelf 3 no longer actively applies force to the cargo door 2 in the opening direction, the cargo door 2 will return to the position closing the delivery port 11 under the action of the first return spring 6; in this process, similarly, the shelf 3 no longer actively applies a pressing force to the anti-theft lock buckle; the anti-theft buckle is returned to the position where the anti-theft lock buckle 5 is buckled on the cargo door 2 under the action of the second return spring 7, so that when the cargo door 2 completely closes the delivery port 11, the anti-theft lock buckle 5 can lock the cargo door 2 again.

In this solution, the third return spring 8 can be a torsion spring.

[0023] Preferably, see Figures 2 to 5 The anti-theft lock buckle 5 is rotatably connected to the cargo box 1, and the anti-theft lock buckle 5 includes a buckle end 51 and a force-applying end 52; when the shelf 3 rotates, the shelf 3 can touch the force-applying end 52, and when the shelf 3 touches the force-applying end 52 and the shelf 3 rotates forward, the anti-theft lock buckle 5 rotates so that the shelf 3 avoids the anti-theft lock buckle 5, and when the shelf 3 touches the force-applying end 52 and the shelf 3 rotates reversely, the shelf 3 can apply force to the force-applying end 52 so that the buckle end 51 rotates away from the cargo door 2.

[0024] Preferably, see Figure 2 The cargo box 1 is also provided with a delivery passage 12 , and the delivery passage 12 is arranged on the other side of the cargo door 2 away from the delivery port 11 .

[0025] Preferably, see Figure 5 and 6 The cargo door 2 is provided with a passageway exit 22. When the cargo door 2 is fully opened, the cargo 9 on the shelf 3 passes through the delivery port 11 and the passageway exit 22 and reaches the delivery passage 12.
