DETAILED DESCRIPTION

[0026] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0027] like Figure 1 and Figure 2 As shown, a vending machine with a pickup port having a linkage anti-theft device comprises a cabinet 1 and a cabinet door 2. The cabinet door 2 is provided with a pickup port 3 connected to the cabinet 1, and the cabinet 1 is provided with a pickup passage 7 connected to the pickup port 3. In this embodiment, a refrigeration device and a shelf (not shown in the figure) are also provided in the inner cavity of the cabinet 1. The refrigeration device is an existing refrigerator for refrigerating the goods placed on the shelf. A control panel (not shown in the figure) is provided on the top of the cabinet 1, and a display screen 20 is provided on the cabinet door 2. The display screen 20 is electrically connected to the control panel. These are all prior arts, which should be understood by those skilled in the art and will not be described in detail here.

[0028] like Figures 2 to 10As shown, a linkage anti-theft device is provided on the pickup port 3 and the pickup channel 7. The anti-theft device adopts a mechanical anti-theft device. When the pickup port is opened, the pickup channel 7 can be closed to prevent thieves from stealing through the pickup channel 7. It should be emphasized here that when the pickup port push plate 4 is opened to the end of the travel, the goods in the pickup port 3 will not be clamped, and the goods will not be damaged or difficult for the user to take out the goods. While taking anti-theft into consideration, it will not affect the pickup. The anti-theft device includes a pickup port push plate 4, a pickup port flip plate 5, and a rotatable anti-theft plate 6. The top of the pickup port push plate 4 is hinged to the pickup port 3 by a hinge, so that the pickup port push plate 4 can be rotated in the direction of the cabinet 1. Similarly, the end of the anti-theft plate 6 is also hinged in the pickup channel 7 by a hinge. A first connecting rod assembly is provided between the pickup port flip plate 5 and the pickup port push plate 4. The pickup port flip plate 5 is flipped upward by following the pickup port push plate 4 through the first connecting rod assembly. In other words, the flipping directions of the pickup port flip plate 5 and the pickup port push plate 4 are the same, both flipping in the direction inside the cabinet 1. The top of the pickup port flip plate 5 is also hinged to the pickup port push plate 4 through a hinge. A second connecting rod assembly is provided between the anti-theft plate 6 and the pickup port flip plate 5. The second connecting rod assembly is provided on the outside of the first connecting rod assembly. During the flipping process of the anti-theft plate, first, the anti-theft plate 6 is flipped by following the action of the pickup port push plate 4 through the second connecting rod assembly. When the anti-theft plate 6 flips upward to a certain angle, the anti-theft plate 6 continues to flip upward under the support of the pickup port flip plate 5. At this time, the pickup port push plate 4 also continues to rotate upward. Therefore, the anti-theft plate 6 continues to flip upward under the joint action of the pickup port flip plate 5 and the anti-theft plate 6, but it is separated into two stages of movement. The first stage is driven by the second connecting rod assembly, and the second stage is driven by the pickup port flip plate 5. Such a design can reduce the height of the pickup port 3, save space, and allow the cabinet 1 to place more goods. Then, the anti-theft plate 6 and the pickup port flip plate 5 cooperate to close the pickup channel 7, so that the pickup channel 7 is closed while the pickup port 3 is opened, which plays a good anti-theft role. In addition, the first connecting rod assembly and the second connecting rod assembly are respectively divided into two groups, and are respectively arranged on both sides of the pickup port push plate 4, the pickup port flip plate 5 and the anti-theft plate 6, so as to play a role of smooth opening. The first connecting rod assembly and the second connecting rod assembly are both arranged in the cabinet 1, which should be understood by those skilled in the art.

[0029] Furthermore, if Figures 2 to 10As shown, the first connecting rod assembly is a two-connecting rod structure, specifically, the first connecting rod assembly includes a push rod 8, a driving rod 9 and a driving wheel 10, one end of the push rod 8 is hinged on the cabinet door 2, and the other end is hinged on the middle part of the driving rod 9, one end of the driving rod 9 is hinged on the picking port push plate 4, and the other end is installed with the driving wheel 10, the driving wheel 10 is slidably connected to the bottom of the picking port flip plate 5, the push rod 8 and the driving rod 9 cooperate and link to make the driving rod 9 open outward, and the driving rod 9 drives the picking port flip plate 5 to flip backward through the driving wheel 10. A hinge seat 11 is provided between the push rod 8 and the cabinet door 2, and the end of the push rod 8 is hinged on the cabinet door 2 through the hinge seat 11. When the pickup port push plate 4 is pushed by an external force, the push rod 8 first rotates upward and lifts the drive rod 9, and then the drive rod 9 opens clockwise in the direction away from the push rod 8 under the push of the push rod 8, and the other end of the drive rod 9 slides along the bottom of the pickup port flip plate 5 through the drive wheel 10, so that the pickup port flip plate 5 can flip upward, thereby realizing the linkage between the pickup port push plate 4 and the pickup port flip plate 5.

[0030] Furthermore, if Figures 2 to 10As shown, the second connecting rod assembly is a three-link structure, specifically, the second connecting rod assembly includes a pull rod 12, a connecting rod 13, a driving rod 14 and a sliding wheel 15, the pull rod 12, the connecting rod 13 and the driving rod 14 are hinged in sequence, the sliding wheel 15 is installed at the head end of the pull rod 12, the sliding wheel 15 is slidably connected to the picking port push plate 4, the driving rod 14 is installed on the side wall of the anti-theft plate 6 and its end is hinged with the anti-theft plate 6 in the picking channel 7, the pull rod 12, the connecting rod 13 and the driving rod 14 cooperate to make the anti-theft plate 6 rotate upward. Under the synchronous upward rotation of the picking port push plate 4, the anti-theft plate 6 is turned upward counterclockwise under the linkage of the pull rod 12, the connecting rod 13 and the driving rod 14, so as to realize the linkage between the picking port push plate 4 and the anti-theft plate 6. Due to the limited space and the position of the second connecting rod assembly, in this design, rollers 60 are provided on both sides of the front end of the anti-theft plate 6. After the anti-theft plate 6 is flipped upward to a certain angle, it contacts the cargo pickup opening flip plate 5 and forms a preliminary function of closing the cargo pickup passage 7. Since the second connecting rod assembly cannot provide the anti-theft plate 6 with the power to continue to flip upward, the rollers 60 can slide upward along the cargo pickup opening flip plate 5 to drive the anti-theft plate 6 to continue to rotate upward, realizing the linkage of the anti-theft plate 6 and the cargo pickup opening flip plate 5 in the latter stage. When the anti-theft plate 6 is parallel to the cargo pickup opening flip plate 5 or the cargo pickup opening flip plate 5 is against the bottom of the anti-theft plate 6, the anti-theft plate 6 and the cargo pickup opening flip plate 5 jointly close the cargo pickup passage 7 to achieve the anti-theft effect. In addition, a support seat 120 is provided on the pull rod 12 near the connecting rod 13. The pull rod 12 is hinged to the support seat 120. The support seat 120 is installed on the inner wall of the cabinet 1. The pull rod 12 acts as a lever through the support seat 120, thereby pulling the connecting rod 13 to move toward the cargo pickup port 3, and finally driving the anti-theft plate 6 to flip upward through the driving rod 14.

[0031] Furthermore, sliding plates 40 are provided on both sides of the cargo pickup port push plate 4, and the sliding wheel 15 is adapted to slide on the sliding plates 40 to realize the linkage between the cargo pickup port push plate 4 and the second connecting rod assembly.

[0032] Furthermore, an upwardly bent inclined plate 61 is provided at the front end of the anti-theft plate 6, and the inclined plate 61 is used to guide the anti-theft plate 6 to contact the cargo pickup port flip plate 5 to prevent the anti-theft plate 6 from being stuck on the cargo pickup port flip plate 5, thereby ensuring that the anti-theft device can work normally.

[0033] In this embodiment, if Fig.11As shown, anti-theft frames 70 are provided on both sides of the picking channel 7, and infrared sensors 71 are provided on the anti-theft frames 70. The anti-theft frames 70 are used to block the gap between the first connecting rod assembly and the second connecting rod assembly to prevent thieves from stealing the goods in the cabinet 1 from both sides of the picking channel 7, and the infrared sensors 71 are used to sense the falling of goods, so that the vending machine can remind users to pick up goods.

[0034] Next, the following will further describe how the pickup port push plate 4, the pickup port flip plate 5 and the anti-theft plate 6 work in conjunction with the accompanying drawings:

[0035] In the initial state, if Figure 3 and Figure 4 As shown, that is, when the pick-up port push plate 4 is closed (the opening angle is 0°), the pick-up port push plate 4, the pick-up port flip plate 5 and the anti-theft plate 6 are all vertically downward and in a vertical state. The push rod 8 is in the same direction as the pick-up port push plate 4, and the driving rod 9 and the push rod 8 form a minimum angle, and the driving wheel 10 is in contact with the bottom surface of the pick-up port flip plate 5. At this time, the pull rod 12 and the connecting rod 13 form the largest angle, the driving rod 14 is in the same direction as the anti-theft plate 6, and the connecting rod 13 and the driving rod 14 form a minimum angle.

[0036] When the pick-up port push plate 5 is opened 21°, Figure 5 and Figure 6 As shown, the pick-up port push plate 5 rotates upward to 21° under the action of external force, and the push rod 8 rotates synchronously with the pick-up port push plate 4. At this time, the push rod 8 acts on the drive rod 9 with an upward thrust, so that the drive rod 9 opens outward counterclockwise. The drive rod 9 pushes the pick-up port flip plate 5 synchronously through the drive wheel 10. At this time, the pick-up port flip plate 5 flips upward, and its rotation angle is greater than the opening angle of the pick-up port push plate 4. The angle between the drive rod 9 and the push rod 8 is gradually increasing. At the same time, the sliding wheel 15 moves along the bottom end of the sliding plate 40, thereby driving the pull rod 12 to rotate clockwise. The pull rod 12 pulls the connecting rod 13 and the driving rod 14 to move toward the direction of the pick-up port 3. At this time, the anti-theft plate 6 flips upward counterclockwise. The angle between the pull rod 12 and the connecting rod 13 is gradually shrinking, and the angle between the connecting rod 13 and the driving rod 14 is gradually shrinking. The cargo-taking opening flip plate 5 is located below the anti-theft plate 6, and the two are not in contact.

[0037] When the pick-up port push plate 5 is opened 27.5°, Figure 7 and Figure 8As shown, the pick-up port push plate 5 rotates upward to 27.5° under the action of external force, and the push rod 8 continues to push the pick-up port flip plate 5 to flip upward through the drive rod 9 and the drive wheel 10. The angle between the drive rod 9 and the push rod 8 is still increasing. The angle at which the pick-up port flip plate 5 is opened under the action of the first connecting rod assembly is greater than the opening angle of the pick-up port push plate 4, and the angle difference between the two is gradually increasing. At the same time, the sliding wheel 15 continues to slide down along the bottom end of the sliding plate 40 and approaches the bottom end of the sliding plate 40. At this time, the pull rod 12 is in a vertical direction, and the connecting rod 13 and the driving rod 14 move toward the direction of the pick-up port 3 under the pull of the pull rod 12 until the roller 60 on the anti-theft plate 6 contacts the pick-up port flip plate 5. At this time, the pick-up port flip plate 5 provides support for the anti-theft plate 6, forming a state of closing the pick-up channel 7. The angle between the pull rod 12 and the connecting rod 13 is further reduced, and the angle between the connecting rod 13 and the driving rod 14 is further reduced.

[0038] When the cargo port push plate 5 is opened 35°, Fig. 9 As shown, the pickup port push plate 5 rotates upward to 35° under the action of external force, and the push rod 8 continues to push the pickup port flip plate 5 to flip upward through the drive rod 9 and the drive wheel 10. The angle between the drive rod 9 and the push rod 8 is still increasing, gradually approaching 90°, and the opening angle of the pickup port flip plate 5 under the action of the first connecting rod assembly is greater than the opening angle of the pickup port push plate 4, and the angle difference between the two is gradually increasing. At the same time, the sliding wheel 15 continues to slide down along the bottom end of the sliding plate 40 and further approaches the bottom end of the sliding plate 40. At this time, the pull rod 12 continues to rotate clockwise, and the pull rod 12 continues to pull the connecting rod 13 and the driving rod 14 to move toward the direction of the cargo pickup port 3. At this time, the roller 60 continues to move along the top of the cargo pickup port flip plate 5, thereby driving the anti-theft plate 6 to continue to flip upward. Since the anti-theft plate 6 is supported by the cargo pickup port flip plate 5, the flipping of the anti-theft plate 6 is faster than the flipping of the driving rod 14. At this time, the flipping of the anti-theft plate 6 is mainly supported by the cargo pickup port flip plate 5, and the anti-theft plate 6 is linked to the cargo pickup port flip plate 5. The angle between the pull rod 12 and the connecting rod 13 is further reduced, and the angle between the connecting rod 13 and the driving rod 14 is further reduced.

[0039] When the cargo port push plate 5 is opened 48°, Fig.10As shown, the pick-up port push plate 5 rotates upward to 48° under the action of external force, and the pick-up port push plate 4 is at its maximum opening angle. The push rod 8 continues to push the pick-up port flip plate 5 to flip upward through the drive rod 9 and the drive wheel 10, and a 90° angle is formed between the drive rod 9 and the push rod 8. At this time, the pick-up port flip plate 5 flips upward to the maximum angle under the action of the first connecting rod assembly, and the difference between the opening angle of the pick-up port flip plate 5 and the opening angle of the pick-up port push plate 4 is the largest. At the same time, the sliding wheel 15 slides to the bottom end of the sliding plate 40, the pull rod 8 is basically parallel to the pick-up port push plate 4, the angle between the pull rod 12 and the connecting rod 13 is the smallest, and the angle between the connecting rod 13 and the driving rod 14 is the largest. When the bottom end of the pickup port flip plate 5 is pressed against the bottom surface of the anti-theft plate 6, a dead angle is formed, which limits the continued rotation of the pickup port push plate 4 and the pickup port flip plate 5, and the roller 60 slides to the highest point of its stroke.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
