BACKGROUND

[0002] In the cigarette retail industry, since there is no loss compensation policy for current tobacco, and due to the particularity of cigarette products, they are extremely easy to be stolen or lost when sold in stores or shops. The above-mentioned safety hazards and other reasons make the sellers still use the traditional closed sales mode when selling cigarettes.

[0003] This traditional closed sales mode (i.e., the sold cigarettes are placed in a closed shelf for display to customers, and customers cannot directly touch the specific cigarette products) has many disadvantages: it not only causes a distance between the displayed cigarettes and customers, and the "self-selling" function of the goods (i.e., through the direct and effective contact and touch of the customers with the sold cigarette products to increase the purchase rate or desire of the customers for the products by the product's own characteristics such as the touch and texture of the products) cannot be fully exerted, which is not conducive to improving the sales volume of the cigarettes; in addition, since the closed sales mode is used, the actual sales process is limited by the limited space of the retail shelves in the actual stores and the large variety of existing cigarette types, so that the types of displayed and sold cigarettes are limited, and most of the types of cigarettes or cigarettes cannot be displayed, which is not conducive to the sales of these types of cigarettes and cannot effectively improve the sales volume of the cigarettes.

DETAILED DESCRIPTION

[0037] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application. As shown in the following embodiments: Figures 1-15

[0038] Embodiment 1:

[0039] Cigarette open shelf lock, including housing assembly 1, limit frame assembly 2, the inner end of the limit frame assembly 2 is movably matched with the inner end of the housing assembly 1, the outer end of the limit frame assembly 2 and the end of the housing assembly 1 form a storage space 3 for placing the product to be sold (cigarettes or cigarettes) 4, the housing assembly 1 adjusts the movement of the inner end of the limit frame assembly 2 to realize the adjustment of the size of the storage space 3, the storage space 3 adjusts the size of its own space to realize the clamping and limiting of the product to be sold (cigarettes or cigarettes) 4 placed inside. ​

[0040] The housing assembly 1 includes a housing consisting of a front housing 101 and a rear housing 102. A lifting and resetting mechanism 5 is installed in the cavity of the housing. A keyhole 103 is provided on the rear housing 102 for a key 6 to pass through to control the lifting and resetting mechanism 5. The top of the front housing 101 is higher than the top of the rear housing 102, and a lower limiting cavity 105 is provided on its upper inner side wall, which is surrounded by a storage tray 104 and a peripheral panel. The lower limiting cavity 105 is used to limit the lower part of the product to be sold (cigarettes or packs of cigarettes) 4. A slot 106 is provided on the top of the rear housing 102 for the inner end of the limiting frame assembly 2 to pass through and limit it. The lifting and resetting mechanism 5 is used to adjust the movement of the inner end of the limiting frame assembly 2.

[0041] The key 6 is used to extend into the rear housing and drive the rotation of the limiting core 502; there is no motion interference between the periphery of the key hole 103 and the key 6.

[0042] The limiting frame assembly 2 comprises an upper baffle, a lower baffle, a left baffle, a right baffle, and a rear baffle. A lintel baffle 201 is fixedly connected to the front side of the upper baffle to limit the upper part of the product to be sold (cigarettes or cigarettes) 4 and forms an upper limiting cavity 202. The distance between the bottom of the lintel baffle 201 and the top of the lower baffle is greater than the height of the product to be sold (cigarettes or cigarettes) 4 placed therein. A limiting protrusion 203 with a raised inner end is fixedly connected to the contact part between the lower baffle and the right baffle. The limiting protrusion 203 is fixedly limited and fixed with the lifting and resetting mechanism 5 through the protrusion at its end.

[0043] The lifting and resetting mechanism 5 includes a circular limiting groove 501 located on the inner wall of the rear housing 102, surrounding the key hole 103. A limiting core 502 is inserted into the circular limiting groove 501. The limiting core 502 has a square keyhole 503 on the side facing the key hole 103, which mates with the key head of the key 6. The square keyhole 503 communicates with the cavity of the housing through a circular hole. A ratchet tooth 504 is integrally connected to the outer wall of the limiting core 502. The ratchet tooth 504 is used to engage with the protrusion on the limiting protrusion 203 to limit the entire limiting frame assembly 2. An elastic locking member 506 is installed in the cavity between the top of the rear housing 102 and the lower baffle of the limiting frame assembly 2. An elastic resetting member 505 is installed in the space between the bottom of the rear housing 102 and the lower baffle of the limiting frame assembly 2.

[0044] The elastic locking member 506 comprises a locking elastic sheet, one end of the elastic sheet is fixedly connected with the rear shell 102, the other end is a free end and abuts against the ratchet tooth 504; the elastic reset member 505 is a reset spring, two ends of the reset spring are fixedly connected with the middle part of the lower baffle of the limiting frame assembly 2 and the middle part of the bottom plate of the rear shell 102 respectively.

[0045] (1) The replenishment principle of the cigarette open shelf lock:

[0046] 1. Before replenishment, the internal part of the cigarette open shelf lock, affected by the top surface structure of the front shell 101 and the rear shell 102, the limiting frame can only move up and down, and affected by the circular limiting groove 501 and the circular limiting column, the limiting core 502 can only rotate with the center of the circular hole of the limiting core 502 as the center. At the same time, the limiting frame is affected by the upward thrust of the reset spring, but the limiting frame cannot move upward due to the limitation of the lower baffle. The limiting core 502 is affected by the counterclockwise elastic force of the reset elastic sheet, but cannot rotate counterclockwise due to the influence of the limiting frame protrusion.

[0047] 2. At this time, the cigarette open shelf lock is in an open state, the size between the lintel baffle 201 and the skirting baffle is greater than the height of the cigarette box, and the cigarette to be replenished can be placed in the limiting frame.

[0048] 3. After the cigarette is placed in the limiting frame, a downward thrust is applied to the limiting frame, and when the downward thrust is greater than the elastic force of the reset spring, the limiting frame moves downward.

[0049] 4. When the limiting frame moves downward, affected by the limiting frame protrusion, the limiting core 502 rotates clockwise with the center of the circular hole of the limiting core 502 as the center, the limiting core 502 protrusion pushes the reset elastic sheet to cause downward bending deformation, and the horizontal distance between the limiting core 502 protrusion and the rotation center gradually decreases.

[0050] 5. Continue to push the limiting frame downward until the limiting frame protrusion and the limiting core 502 protrusion are separated from each other.

[0051] 6. After the limiting frame protrusion and the limiting core 502 protrusion are separated from each other, the limiting core 502 rotates counterclockwise under the influence of the elastic force of the reset elastic sheet, and returns to the state before replenishment.

[0052] 7. Stop applying downward pressure to the limiting frame, and under the influence of the elastic force of the reset spring, the limiting frame moves upward by a small distance, until the upper edge of the limiting frame protrusion and the lower edge of the limiting core 502 abut, and under the limitation of the limiting core 502, the limiting frame stops moving upward.

[0053] 8. After the limit frame stops moving upward, the cigarette rack lock is locked. The distance between the lintel baffle 201 and the kick baffle is less than the height of the cigarette box. In addition, the cigarettes are restricted by multiple baffles and cannot be taken out from the limit frame. The restocking process ends.

[0054] (II) The principle of cigarette shelf lock sales:

[0055] 1. Before unlocking and retrieving the cigarettes, the cigarettes are locked in the limiting frame of the cigarette rack lock. The limiting frame cannot move upward, and the cigarettes are restricted by multiple baffles, making it impossible to remove them from the limiting frame.

[0056] 2. Inside the cigarette rack lock, the limiting frame can only move up and down due to the influence of the top structure of the front outer shell 101 and the rear outer shell 102. The limiting core 502 can only rotate around the center of its circular hole due to the influence of the circular limiting groove 501 and the circular limiting post. Simultaneously, the limiting frame is affected by the upward pushing force of the return spring, but because the protrusion of the limiting frame is restricted by the protrusion of the limiting core 502, the limiting frame cannot move upward. The limiting core 502 is affected by the counterclockwise elastic force of the return spring, but cannot rotate counterclockwise due to the influence of the rear baffle. At this position, the square key hole 6 coincides with the square hole of the limiting core 502.

[0057] 3. Insert the key 6 into the square key hole of the rear housing 102. The square key head of the key 6 is inserted into the square hole of the limiting core 502. The cylinder of the key 6 is exactly in the square key hole.

[0058] 4. Turn the key 6 handle clockwise. Because the cylindrical key 6 is exactly in the square key hole, the rear outer casing 102 does not rotate with the key 6. However, since the square key head is in the square hole of the limiting core 502, the limiting core 502 will rotate clockwise with the key 6 around the center of the circular hole of the limiting core 502.

[0059] 5. The limiting core 502 continues to rotate clockwise. The protrusion of the limiting core 502 pushes the reset spring, causing it to bend downward. At the same time, the horizontal distance between the protrusion of the limiting core 502 and the center of rotation gradually shortens until the protrusion of the limiting core 502 disengages from the protrusion of the limiting frame.

[0060] 6. After the limit core 502 protrusion separates from the limit frame protrusion, the limit frame moves upward under the influence of the upward pushing force of the reset spring.

[0061] 7. The limit frame continues to move upward until the top surface of the limit frame protrudes and the bottom surface of the lower baffle, at which point the movement stops.

[0062] 8. After the limit frame stops moving, the key 6 is released. Under the influence of the spring force of the reset spring, the limit core 502 rotates counterclockwise, so that the square hole of the limit core 502 coincides with the square key 6 hole, and returns to the state before unlocking.

[0063] 9、Limiting core 502 square hole and square key 6 hole coincides after, the key 6 is taken out from the square key 6 hole.

[0064] 10、After the limiting frame moves up, the size between the lintel baffle 201 and the toe baffle becomes larger, which is larger than the height of the cigarette case, the cigarette is taken out from the limiting frame, and the unlocking and selling process is ended.

[0065] (Three) replenishment process:

[0066] 1、Before replenishment starts, the cigarette open rack lock is in an open state, and the limiting frame is pushed out upward under the influence of the elastic force.

[0067] 2、After starting replenishment, the clerk places the same kind of cigarette into the cigarette open rack lock, each cigarette open rack lock can place 1 box (or 1 strip) of cigarettes, and presses the limiting frame downward to close the cigarette open rack lock.

[0068] 3、The same kind of cigarette is placed on the card reading and unlocking integrated machine, the refresh button is clicked, the card reading and unlocking integrated machine automatically acquires the ID of the radio frequency card built in the cigarette open rack lock, and the clerk checks the number of the radio frequency card ID to prevent errors.

[0069] 4、The clerk selects the corresponding cigarette brand on the self-service terminal or scans the barcode of the cigarette to obtain the brand of the cigarette, and then clicks the confirmation button, so that the self-service terminal automatically binds the ID of the part of the radio frequency card with the ID of the brand of the cigarette to the uploading server. The brand of the cigarette on the server corresponds to the basic information such as the price of the cigarette one by one.

[0070] 5、After uploading successfully, the server feeds back the information of successful replenishment to the self-service terminal.

[0071] 6、After the clerk sees the information of successful replenishment, the cigarette open rack lock is taken off from the card reading and unlocking integrated machine, and one time of replenishment is completed.

[0072] 7、Continue to repeat the above operation, after all the cigarettes are replenished, the open rack lock containing the cigarettes is placed on the cigarette open rack shelf for sale.

[0085] There are two ways for the cigarette open shelf lock in actual use. One is that the cigarette open shelf lock loaded with products to be sold is freely placed on the open shelf cabinet to limit and protect the products, so that the products to be sold can be easily distinguished from the cigarettes brought by consumers when theft occurs, and the products can be quickly distinguished even in places without monitoring, so that the probability of product loss is reduced. The other is that the cigarette open shelf lock loaded with products to be sold is fixed on the open shelf cabinet through a limiting rope, so that the cigarette open shelf lock can freely move within a certain range to facilitate consumers to hold and observe, and at the same time, the products to be sold are limited and protected.

[0086] The following is selected:

[0087] The radio frequency card and the acoustic magnetic anti-theft coil are arranged in each cigarette open shelf lock, and the specific size is selected according to the packaging size of cartons and cartons.

[0088] A card reading and unlocking integrated machine (which is internally provided with a radio frequency card reader and an automatic unlocking mechanism) is purchased.

[0089] An existing self-service terminal (which is internally provided with a face recognition module, a receipt printing module and a code scanning module).

[0090] Existing technology interpretation: The radio frequency card and the acoustic magnetic coil belong to the technology familiar in the industry (supermarket loss prevention and theft prevention). The radio frequency card is mainly used for identification and inventory of goods in the loss prevention mechanism, and can be repeatedly used when placed in the mechanism. The acoustic magnetic coil is mainly used in cooperation with the existing access control system. When the acoustic magnetic coil passes through the access control, it will resonate with the electromagnetic wave emitted by the access control. After the access control detects the resonance of the frequency, an alarm is given.

[0091] In the actual open shelf sales process, a plurality of cigarette open shelf locks are arranged and placed on the cigarette open shelf rack, and a plurality of products (cigarettes or cigarettes) 4 to be sold are respectively locked in the cigarette open shelf locks of different sizes.

[0092] After the cigarettes are placed inside the cigarette open shelf lock and locked, it can only be opened by the matching key 6, and the sound magnetic coil and the radio frequency card can be placed inside the cigarette open shelf lock mechanism according to the needs. The sound magnetic coil cooperates with the access control to play the role of anti-theft alarm. The radio frequency card cooperates with the card reader to identify and count the goods in the loss prevention mechanism, and the radio frequency card can be repeatedly read and written.

[0093] The method for realizing the self-service sales of cigarettes in the open shelf comprises the following steps:

[0094] S1: Selecting products:

[0095] The consumer selects the cigarette brand he needs to buy from the cigarette open shelf rack (the cigarettes in the cigarette open shelf rack are locked in the cigarette open shelf lock);
