[0042] To describe in detail the technical content, structural features, achieved objectives and effects of the utility model, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementation manners of the utility model. However, various exemplary embodiments can also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shapes, structures and characteristics of the exemplary embodiments can be used or implemented in another exemplary embodiment.

[0043] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. can explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0044] In addition, in the present application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (e.g., as in "side wall"), etc. are used to describe the relationship between one element and another (other) element as shown in the drawings. The spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped, an element described as "under" or "beneath" another element or feature will then be positioned "above" the other element or feature. Thus, the exemplary term "under" can include both the upper and lower orientations. In addition, the device can be positioned otherwise (e.g., rotated 90 degrees or in other orientations), and accordingly, the spatial relative descriptors used herein are interpreted.

[0045] In the present application, unless otherwise clearly defined and limited, the term "connected" shall be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium.

[0046] The embodiment of the present application provides a display cabinet, which can also be referred to as a showcase, wine cabinet, refrigerator, low-temperature cabinet, beverage cabinet, etc. The display cabinet can be used for storing, displaying, or selling items such as food, medicine, beverages, etc. Usually, a refrigeration system or a heating system is also provided inside the display cabinet to provide different storage temperatures. The display cabinet can be set as a desktop display cabinet suitable for placing on a desktop according to actual needs, or can be set as a floor-standing display cabinet for placing on the ground. The embodiment of the present application does not make special restrictions on the specific size and form of the above display cabinet.

[0047] Please refer to Figure 1 , which shows the front view of the display cabinet provided by the embodiment of the present application. As can be seen from the figure, the display cabinet includes a cabinet body 100 and a base 300 arranged up and down. The front side of the display cabinet has a transparent observation window, and the commodities displayed inside can be observed through the door body.

[0048] Viewed from the front directly, the display cabinet is an axisymmetric structure. The cabinet body 100 has a square outer contour, and the base 300 is generally trapezoidal. Thus, a shape different from that of traditional refrigerators, cold cabinets, and traditional display cabinets can be formed, bringing different visual experiences to users. As an alternative, in other embodiments of the present application, viewed from the front, the cabinet body can also adopt shapes such as circular, heart-shaped, triangular, pentagonal, pentagram-shaped, hexagonal, or octagonal, or the cabinet body has a quadrilateral geometric structure, such as a rhombus or a rectangle.

[0049] Figure 1In the illustrated embodiment, there are multiple lanes 500 inside the cabinet body 100. Different from traditional display cabinets, there are no shelves inside the cabinet body. The multiple lanes 500 can be staggered from each other and are not connected to each other. In some embodiments, the cabinet body 100 can also adopt the structure of a traditional multi-layer shelf to display goods. To adapt to different cabinet shapes, the lengths and heights of each layer of the shelf may vary slightly.

[0050] In one embodiment, the horizontal heights of two adjacent lanes inside the cabinet body 100 are different. Each lane 500 is separately fixed on the back panel 120 of the cabinet body 100. In this way, on the one hand, the heights of the items placed in each lane can be different, and on the other hand, the multiple lanes can also be flexibly installed and adjusted according to the shape of the cabinet body, maximizing the use of the space inside the cabinet.

[0051] Refer to Figures 2-3 , the front part of the cabinet body 100 has an opening. The display cabinet further includes a door body 200 that can close the opening. The interior of the cabinet body 100 forms a storage bin for accommodating and storing goods. After opening the front door body 200, the storage bin is completely open, and consumers can take the goods in the storage bin by themselves.

[0052] In this embodiment, as Figure 3 shown, the left side part of the door body 200 is rotatably connected to the cabinet body 100 through a hinge 131. To facilitate opening the door, a door handle 240 is also provided at the lower border of the door body 200. This embodiment provides a typical example of a right-opening door. As an alternative, in other embodiments, the display cabinet can also adopt forms such as left-opening, top-opening, or bottom-opening. Refer to Figure 3 shown, the door body 200 can be changed to a left-opening door according to user needs.

[0053] The door body 200 is composed of a frame body 210 and a hollow glass 220. Among them, the frame body 210 is filled with heat-insulating foam material, and a sealing strip 230 is installed on the rear side surface of the door body 200 close to the cabinet body 100. The hollow glass can provide a transparent observation window, enabling consumers to clearly observe the goods stored in the storage bin.

[0054] In a free-use scenario, such as in ordinary household use or inside a commercial entity, there is no need to set up a payment system and door locks and other devices between the door body and the cabinet body. For use in a commercial payment scenario, a lock mechanism also needs to be set up between the door body and the cabinet body. For example, the door body can be provided with a magnetic absorber, and correspondingly, an electromagnetic lock is provided at the cabinet body 100. In the normal state, the magnetic absorber and the electromagnetic lock are attracted and fixed. After the consumer pays, the electromagnetic lock is powered off, releasing the magnetic absorber, and the door body can be opened. In some embodiments, an ordinary mechanical lock can also be used to replace the one between the door body and the cabinet body.

[0055] Please refer to Figure 4 ,5 , the cabinet body 100 includes a plurality of enclosing side walls, and transparent observation windows are respectively provided on the left and right side walls of the cabinet body 100. The provision of this observation window makes the internal display effect of the display cabinet better, and can present a bright and transparent internal space in cooperation with the lighting system.

[0056] In order to maintain the heat preservation performance of the cabinet body and improve the convenience and integrity of the installation of the display cabinet, in this embodiment, the cabinet body 100 and the base 300 adopt a split structure, that is, the two are separately processed and manufactured, and finally fixed and assembled through fasteners. The cabinet body 100 adopts a foaming structure, and a storage bin is formed inside, which has a good heat insulation and heat preservation function, while the base 300 is made of metal components or sheet metal parts, and a placement bin for installing a refrigeration system or a heating system is formed inside. The cabinet body 100 includes an inner sheet metal part and an outer sheet metal part, and a foaming material is filled between the inner sheet metal part and the outer sheet metal part. Please refer to Figure 3 , 6 , as shown in Fig. 7, the base 300 is located directly below the cabinet body 100, and the central axis of the cabinet body vertically passes through the base. The base 300 is bent from a stainless steel plate, a painted steel plate, etc., and components of the refrigeration system such as a compressor and a condenser can be installed inside the base.

[0057] To achieve the best lighting effect, in an embodiment of the present application, the lighting system includes a plurality of light strips. Among them, four light strips are provided at the opening of the cabinet body and are respectively embedded and installed on each side wall. A lamp holder can also be installed between two adjacent side walls. A slot is provided on the lamp holder, and the light strip is fixed on the lamp holder through the slot. Since the lamp holder extends along the front-rear direction, the entire cabinet body can be illuminated.

[0058] Figure 7 In the embodiment shown, the base 300 includes a left side plate 301, a right side plate 302, a bottom plate 303 and a decorative plate 310. The left side plate 301, the right side plate 302 and the bottom plate 303 are bent from a stainless steel plate to form a trapezoidal table with an upper opening, and the lower part of the cabinet body 100 is placed at the upper opening of the trapezoidal table. When assembling the cabinet body and the base, first, the left side plate 301 and the right side plate 302 of the base 300 are respectively fixed on the cabinet body 100 through fasteners, and then the decorative plate 310 is installed on the outside. The decorative plate 310 can be made of materials such as color steel plates and coated galvanized plates by bending. It should be noted that in order to make the product center stable and the support stable, the base as a whole presents a shape with a narrow upper part and a wide lower part. In other alternative embodiments, the shape of the base can also be a frustum of a cone, an I-shaped, etc., which does not limit the protection scope of the application here.

[0059] To stably fix the cabinet body and the base, the left side plate 301 and the right side plate 302 of the base 300 are respectively provided with flanges 304. When the cabinet body 100 is placed on the base 300, the lower side walls of the cabinet body 100 are respectively opposite to the flanges on the left side plate 301 and the right side plate 302, and are fixed by threaded fasteners. Finally, the decorative plate 310 is buckled on the outer sides of the left side plate and the right side plate.

[0060] Please continue to refer to Figure 7 , the display cabinet further includes a rear sealing plate 140 located behind the cabinet body 100 and the base 300. The rear sealing plate 140 can cover the rear surfaces of both the cabinet body 100 and the base 300 at the same time. On the one hand, this can make the rear part of the display cabinet form an integral whole. On the other hand, it is convenient for maintenance. As long as the rear sealing plate 140 is disassembled, the refrigeration system inside the base 300 can be repaired. In addition, to achieve a harmonious and beautiful design effect, the projections of the outer contours of the cabinet body 100 and the base 300 in the front-rear direction are the same as the outer contour of the rear sealing plate 140.

[0061] In this application, through the up-and-down split structure design, the cabinet body and the base have independent structures and can be manufactured separately and finally assembled. The whole cabinet body is made by the foaming process, and a storage bin with good heat preservation effect is formed inside. While the base is made by bending sheet metal parts, with good supporting performance and a hollow interior, which can form a space for placing components such as compressors and condensers. On the other hand, due to the split design of the cabinet body and the base, the cabinet body and the base have a larger design space and can adopt richer geometric shapes, bringing a unique display effect to the whole display cabinet.

[0062] See Figures 8-13 , in the embodiment of this application, each goods channel 500 is separately fixed on the rear back panel 120 of the cabinet body. There is a goods channel outlet in front of the goods channel 500, and a push plate mechanism 520 is arranged behind the goods channel. Each goods channel adopts a non-powered goods channel, and no power components such as motors need to be arranged on the goods channel. Instead, an elastic energy storage element applies a thrust force pointing to the goods channel outlet to the goods in the goods channel.

[0063] Specifically, the goods channel 500 includes:

[0064] A bracket assembly 510, which is used to fixedly support the goods channel on the rear back panel 120 and at the same time provides a storage space for displaying goods. The bracket assembly 510 has a pair of opposite left side walls 514, right side walls 515 and a bottom wall 516 connecting the left side wall and the right side wall. And the left side wall 514, the right side wall 515 and the bottom wall 516 jointly define a long strip-shaped goods channel, and multiple bottled or canned goods are arranged in sequence in the goods channel.

[0065] The pusher mechanism 520 is movably mounted on the bracket assembly 510. The pusher mechanism 520 includes a pusher plate 521 and a coil spring 522. The pusher mechanism continuously provides a thrust force F1 in the direction of the exit of the product channel to the products stored in the product channel. Please refer to Figure 19 , one end of the coil spring 522 is fixed on the pusher plate 521, and the other end is fixed on the front end of the bracket assembly 510. When the product channel is filled with products, the pusher plate 521 is located at the rearmost side, the coil spring 522 is deformed by force, and continuously exerts a forward restoring force on the pusher plate 521. In this embodiment, the coil spring is specifically a variable force coil spring. In other embodiments of the present application, the coil spring can also be replaced by other springs such as tension springs and compression springs.

[0066] The discharging mechanism 530 is provided at the exit of the front part of the product channel. The discharging mechanism 530 includes a pair of limiting plates 531 and a pair of spring plungers 534. Of course, the limiting plates provided in the embodiments of the present application are not limited to the structures shown in the figures, and can also be in various shapes such as flat plates, long strips, and arc plates.

[0067] A pair of limiting plates 531 are respectively rotatably provided on the left side wall 514 and the right side wall 515 of the goods channel 500, and in the normal state, the pair of limiting plates 531 block in front of the exit of the product channel, as shown in Figure 8 , 10 , 11; A pair of spring plungers 534 are respectively fixed on the left side wall 514 and the right side wall 515 of the goods channel 500, and are located within a distance less than the length of one product behind the pair of limiting plates 531. In the normal state, the spring plungers 534 are in an uncompressed state, and their steel balls 5340 can partially extend into the product channel and get stuck on the side of the product. When the user needs to take out the product on the goods channel, hold the first product 601 at the exit of the product channel and apply a general force forward, then the first product 601 can move forward, simultaneously compress the spring plungers 534, and push open the pair of limiting plates 531. After the first product 601 is taken out, the pair of limiting plates 531 and the pair of spring plungers 534 immediately return to their original positions in the normal state, the pusher plate 521 pushes the rear products forward, and the pair of spring plungers 534 prevent the rear products from moving forward along the product channel.

[0068] See Figures 14-19 , the goods channel 500 includes a lower support plate 511 and a goods channel lining 512 mounted on the lower support plate 511. The lower support plate 511 is formed by bending a metal plate, and the goods channel lining 512 is processed by injection molding. The goods channel lining 512 has a pair of slide rails 5122, and chutes are respectively opened on the left and right sides of the pusher plate 521. The pusher plate 521 is slidably engaged with the pair of slide rails by means of the chutes.

[0069] A pair of mounting shafts 532 are respectively arranged at the front end of the inner lining 512 of the goods lane, and a pair of limiting plates 531 are respectively rotatably connected to each mounting shaft 532. In order to enable the limiting plate 531 to automatically reset after rotation, a limiting plate reset spring 533 is respectively arranged between each limiting plate 531 and the inner lining 512 of the goods lane. The reset spring is a torsion spring or a coil spring capable of providing rotational torque.

[0070] See Figure 16 , 17 As shown, the spring plunger 534 includes a plunger 5341, a compression spring 5342 and a steel ball 5340. The plunger 5341 is embedded and installed in the inner lining 512 of the goods lane and is located below the limiting plate 531. Under the action of the compression spring 5342, the steel ball 5340 always partially extends out of the plunger, so that the distance between a pair of steel balls 5340 is less than the width of the goods channel and less than the width of the goods sold. In this embodiment, a pair of spring plungers 534 can be used to slow down the movement of the goods behind and prevent the goods behind from diving forward out of the goods channel under the thrust of the push plate.

[0071] In some embodiments, as an alternative to this solution, the spring plunger can also be replaced by a spring plate, and the convex part of the spring plate faces the goods channel, so that the distance between a pair of spring plates is less than the width of the goods channel and the goods sold, so as to achieve the purpose of buffering the movement speed of the goods. The structure of the spring plate can adopt a "Ω" structure, or the spring plate is fixed to the inner lining of the goods lane with one side inclined, and the other side is a free end, and the free end extends forward and inward into the goods channel to form a channel for the goods to move unidirectionally from back to front.

[0072] In some embodiments, the spring plunger can be replaced by a convex block capable of elastic deformation. The convex block is made of a material with a friction coefficient greater than that of the inner lining of the goods lane, such as rubber material, silica gel material, TPU material, etc., or the surface of the convex block is provided with an uneven structure to increase the friction force. When the goods pass through the convex block, the friction force can be significantly increased and the goods delivery speed can be reduced.

[0073] The lower support plate 511 has a horizontally extending horizontal portion, wing flanks 5113 located on both sides of the horizontal portion, and a pair of hook portions 5111 located at the rear end of the horizontal portion. The lower support plate is integrally bent. Hanging hook holes adapted to the hook portions 5111 are formed in the rear back plate 140 of the cabinet body 100. The lower support plate 511 is detachably connected to the hanging hook holes on the rear back plate 140 through the pair of hook portions 5111. In order to adapt to commodities of different heights, we also hope to be able to flexibly adjust the height between the upper and lower rows of lanes. For this purpose, multiple rows of hanging hook holes exceeding the number of lanes can be formed in the rear back plate 140, so that the lanes 500 can be installed in different hanging hook holes according to the height of the commodities. In order to install the coil spring 522, a front positioning piece 5114 is provided at the front end of the lower support plate 511, and a rear positioning piece 5112 is provided at the rear end. Mounting holes are respectively formed in the front positioning piece 5114 and the rear positioning piece 5112. One end of the coil spring 522 is fixed to the front positioning piece 5114 by screws, and the other end of the coil spring is fixed to the push plate 521.

[0074] In the display cabinet of the present application, each lane is independent of each other and is respectively fixed to the cabinet body. Through the push plate mechanism and the goods discharging mechanism, the lane can push the commodity forward without power, and there is no need to connect complex transmission mechanisms and circuits, etc. Therefore, a merchant can fix each lane at any position on the rear back plate according to the height of the commodity or the display requirement, so as to flexibly display the commodity and achieve a special visual effect.
