[0056] Combined with Figures 1 to 10 As shown, in some embodiments, a display cabinet is provided. The display cabinet includes a cabinet body 1, a door body 2, a door lock assembly 3 and a refrigeration system.

[0057] The cabinet body 1 has a rectangular three-dimensional structure. The cabinet body 1 includes an outer shell 11 and an inner liner. A storage chamber is defined in the inner liner. The opening of the storage chamber faces forward. The storage chamber is used for refrigerating and preserving food or beverages.

[0058] Of course, the layout of the inner liner can be arranged according to actual needs. For example, a freezing chamber can also be added to the inner liner.

[0059] In order to improve the heat preservation effect and the overall structural strength of the display cabinet, foaming material is filled between the cabinet body 1 and the inner liner.

[0060] Combined with Figure 1 and Figure 6 As shown, one side of the door body 2 is hinged to the cabinet body 1 through a hinge 21, facilitating the opening and closing of the storage chamber by rotating the door body 2. The door body 2 can be a glass door, facilitating users to observe the items in the storage chamber.

[0061] A lighting lamp (not shown in the figure) is provided in the inner liner, facilitating sales at night.

[0062] A support plate is connected to the bottom of the outer casing 11, and a partition is provided below the inner container. A press chamber 13 is formed by enclosing between the partition and the support plate.

[0063] The refrigeration system includes a compressor, a condenser, a fan motor, an expansion valve, and an evaporator. The compressor, the condenser, the expansion valve, and the evaporator are connected by pipelines to form a refrigerant circulation loop.

[0064] The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle process includes a series of processes involving compression, condensation, expansion, and evaporation to achieve refrigeration of the items in the inner container. The compressor, the condenser, and the fan motor are located in the press chamber 13, and the evaporator is arranged at the top of the inner container.

[0065] First, the low-temperature and low-pressure refrigerant gas enters the compressor, and the compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure refrigerant gas and discharges it. The discharged refrigerant gas flows into the condenser for condensation. Under the action of the fan motor, the condensation process of the condenser can be accelerated. In the condenser, the refrigerant condenses into a liquid phase, and under the action of the fan motor, heat is released to the surrounding environment through the condensation process.

[0066] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed by condensation in the condenser into a low-temperature and low-pressure liquid-phase refrigerant. The low-temperature and low-pressure liquid-phase refrigerant enters the evaporator, evaporates the refrigerant expanded in the expansion valve in the evaporator, and returns the refrigerant gas in the low-temperature and low-pressure state to the compressor. The evaporator can refrigerate the gas environment in the inner container by utilizing the latent heat of evaporation of the refrigerant.

[0067] A plurality of partition shelves (not shown in the figure) are equidistantly arranged on the left and right side walls of the inner container. A plurality of storage mesh plates are installed on the partition shelves. Drinks are placed on the storage mesh plates, and the height of the storage mesh plates can be adjusted as needed.

[0068] Combined Figure 2 、 Figure 3 and Figure 5 As shown in, the door lock assembly 3 includes a first fixed seat 31, a second fixed seat 32, and a linkage mechanism 33.

[0069] The first fixed seat 31 is fixed to the support frame at the front of the cabinet body 1 by screws, and a first padlock hole 311 is formed on the first fixed seat 31.

[0070] Combined Figure 10As shown, the first fixing base 31 includes a connecting plate 312, side plates 313 and a top plate 314. Among them, the connecting plate 312, side plates 313 and top plate 314 are fixedly connected to each other in pairs. The connecting plate 312 and side plates 313 are in the vertical direction, the side plates 313 are arranged in pairs, and there is a gap between the two side plates 313. The top plate 314 is in the horizontal direction. The connecting plate 312 is fixed to the cabinet body by screws. Second padlock holes 3331 are provided on the side plates 313 and top plate 314 as required.

[0071] To improve the overall aesthetic appearance of the display cabinet, when the door body 2 is in the closed state, the first fixing base 31 does not protrude from the outer surface of the door body 2.

[0072] The second fixing base 32 is fixed to the cabinet body 1 by screws. A locking portion 321 is formed on the second fixing base 32. The locking portion 321 has an open groove-like structure. The opening of the locking portion 321 faces the outside of the outer casing 11, so that it is convenient for the main body portion 3311 to be inserted into the locking portion 321.

[0073] By the same token, to improve the overall aesthetic appearance of the display cabinet, when the door body 2 is in the closed state, the second fixing base 32 does not protrude from the upper surface of the door body. On the one hand, it is convenient for packaging and transportation and avoids generating stress concentration points.

[0074] One of the first fixing base 31 and the second fixing base 32 is located above the door body 2, and the other is located below the door body 2.

[0075] The linkage mechanism 33 is provided on the door body 2 and is rotatably connected to the door body 2. A second padlock hole 3331 is formed at one end of the linkage mechanism 33, and a limiting member 331 is formed at the other end of the linkage mechanism 33. The linkage mechanism 33 is configured such that when the door body 2 is in the closed state and the linkage mechanism 33 is rotated, when the second padlock hole 3331 coincides with the first padlock hole 311, the limiting member 331 is inserted into the locking portion 321.

[0076] Specifically, as shown in Figure 3 As shown, by providing the door lock assembly 3, when the door body 2 is in the closed state and the linkage mechanism 33 is rotated, the second padlock hole 3331 coincides with the first padlock hole 311. The door body 2 can be locked to the cabinet body 1 by passing a traditional padlock through the first padlock hole 311 and the second padlock hole 3331.

[0077] At the same time, the limiting member 331 is inserted into the locking portion 321 to lock the other end of the door body 2 to the cabinet body 1, thereby preventing the upper and lower ends of the door body 2 from being opened, improving the safety of the display cabinet, solving the risk of theft of goods, and being beneficial to improving the user experience effect and product competitiveness.

[0078] Next, taking the case where the first fixing base 31 is located below the door body 2 and the second fixing base 32 is located above the door body 2 as an example for illustration.

[0079] Specifically, the second fixing base 32 can be fixed to the top of the outer casing 11 or can be embedded in the outer casing 11.

[0080] Correspondingly, the limiting member 331 is located at the upper end of the linkage mechanism 33 and corresponds to the second fixing base 32, and the second padlock hole 3331 is located at the lower end of the linkage mechanism 33 and corresponds to the first fixing base 31.

[0081] In some embodiments of the present application, in combination with Figure 9 and Figure 10 as shown, the linkage mechanism 33 includes a connecting shaft 332 and a lock piece 333.

[0082] The connecting shaft 332 has a cylindrical rod-like structure. The connecting shaft 332 is arranged vertically in the door body 2 and is rotatably connected to the door body 2. The limiting member 331 is fixedly connected to the upper end of the connecting shaft 332.

[0083] One end of the lock piece 333 is fixedly connected to the lower end of the connecting shaft 332. A second padlock hole 3331 is formed at the other end of the lock piece 333. The position of the second padlock hole 3331 corresponds to that of the first padlock hole 311.

[0084] When the first padlock hole 311 is on the vertical plane of the first fixing base 31, the second padlock hole 3331 is on the vertical plane of the lock piece 333; when the first padlock hole 311 is on the horizontal plane of the first fixing base 31, the second padlock hole 3331 is on the horizontal plane of the lock piece 333. Only in this way can it be ensured that when the linkage mechanism 33 rotates, the second padlock hole 3331 and the first padlock hole 311 coincide.

[0085] It should be noted that the coincidence of the second padlock hole 3331 and the first padlock hole 311 means that the position where a traditional padlock can pass through the second padlock hole 3331 and the first padlock hole 311 simultaneously to lock the door body 2 and the cabinet body 1 can be referred to as the coincidence of the second padlock hole 3331 and the first padlock hole 311.

[0086] In some embodiments of the present application, the lock piece 333 includes a horizontal plate section 3332 and a vertical plate section 3333. The horizontal plate section 3332 is fixedly connected to the connecting shaft 332 by welding or fasteners. The vertical plate section 3333 is connected to the horizontal plate section 3332 at a predetermined angle. The second padlock hole 3331 is formed on the vertical plate section 3333.

[0087] Exemplarily, the vertical plate section 3333 is perpendicularly connected to the horizontal plate section 3332 to form an L-shaped connection structure. Among them, the vertical plate section 3333 is located above the horizontal plate section 3332.

[0088] In some embodiments of the present application, the second fixing seat 32 includes a fixing plate section 322 and a stop plate section 323. The fixing plate section 322 is fixedly connected to the cabinet body 1. The fixing plate section 322 and the stop plate section 323 are connected at a predetermined angle, and a locking portion 321 is formed at the connection portion between the fixing plate section 322 and the stop plate section 323.

[0089] Exemplarily, the fixing plate section 322 and the stop plate section 323 are perpendicularly connected to form an L-shaped structure. The stop plate section 323 is located above the fixing plate section 322, and the fixing plate section 322 and the stop plate section 323 are of an integrally formed structure.

[0090] In some embodiments of the present application, the limiting member 331 includes a main body portion 3311.

[0091] The main body portion 3311 is fixedly connected to the connecting shaft 332. Specifically, the two can be fixedly connected by welding or fasteners. Driven by the connecting shaft 332, the main body portion 3311 can be rotated into or out of the locking portion 321.

[0092] It should be noted that the upper wall surface of the locking portion 321 is higher than the upper surface of the main body portion 3311 of the limiting member 331, and the upper surface of the fixing plate section 322 is lower than the lower surface of the main body portion 3311 of the limiting member 331, so as to ensure that the main body portion 3311 can be rotated into the locking portion 321.

[0093] When the main body portion 3311 is rotated into the locking portion 321, in the vertical direction, the second fixing seat 32 plays a limiting role on the limiting member 331.

[0094] In some embodiments of the present application, the limiting member 331 further includes a bent portion 3312.

[0095] The bent portion 3312 is connected to the end of the main body portion 3311 away from the connecting shaft 332. Specifically, the bent portion 3312 is perpendicularly connected to the main body portion 3311. The bent portion 3312 is located above the main body portion 3311, and the bent portion 3312 and the main body portion 3311 are of an integrally formed structure; as shown in Figure 2 and Figure 3 When the main body portion 3311 is rotated into the locking portion 321, when the door body 2 is to be opened, the bent portion 3312 abuts against the stop plate section 323, and the bent portion 3312 and the stop plate section 323 prevent the upper part of the door body 2 from being opened.

[0096] In some embodiments of the present application, the main body portion 3311 is perpendicular to the locking piece 333. As shown in Figure 2 and Figure 3, so that when the door body 2 is in the closed state, the main body portion 3311 is located in the locking portion 321, the external lock locks the lower end of the door body 2, and both the upper and lower ends of the door body 2 are in the locked state. At this time, if the external lock is removed and the connecting shaft 332 of the linkage mechanism 33 is rotated counterclockwise by 90°, the state at this time is as Figure 7 and Figure 8 shown, the door body 2 and the cabinet body 1 will be in the unlocked state, and the user can open the door body 2.

[0097] In some embodiments of the present application, in combination with Figure 4 shown, the door body 2 is formed with a mounting hole 22 in the vertical direction, the connecting shaft 332 is arranged in the mounting hole 22, the upper part of the connecting shaft 332 is formed with a retaining edge 3321, the retaining edge 3321 is in an annular structure, the retaining edge 3321 and the connecting shaft 332 are of an integral forming structure, and the retaining edge 3321 is configured to prevent the connecting shaft 332 from falling in the vertical direction.

[0098] In some embodiments of the present application, an annular groove (not shown in the figure) is formed at the upper end of the connecting shaft 332, and the main body portion 3311 of the limiting member 331 is arranged in the annular groove and fixed together with the connecting shaft 332. The annular groove plays a role in restricting the limiting member 331 to prevent the limiting member 331 from falling off the connecting shaft 332.

[0099] Specifically, the limiting member 331 and the connecting shaft 332 can be connected by welding or other means.

[0100] In the present application, the limiting member 331, the connecting shaft 332 and the lock piece 333 are an integral structure, and the three are linked together and the relative positions between them are fixed.

[0101] In some embodiments, a display cabinet is provided, and the display cabinet includes a cabinet body 1, a door body 2 and a door lock assembly 3.

[0102] A storage chamber is defined in the cabinet body 1.

[0103] The door body 2 is used to open and close the storage chamber.

[0104] The door lock assembly 3 includes a first fixed seat 31, a second fixed seat 32 and a linkage mechanism 33.

[0105] The first fixed seat 31 is fixed on the cabinet body 1, and a first padlock hole 311 is formed on the first fixed seat 31;

[0106] The second fixed seat 32 is fixed on the cabinet body 1, and a locking portion 321 is formed on the second fixed seat 32. One of the first fixed seat 31 and the second fixed seat 32 is located above the door body 2, and the other is located below the door body 2.

[0107] The linkage mechanism 33 is provided on the door body 2 and is rotatably connected to the door body 2. One end of the linkage mechanism 33 is formed with a second padlock hole 3331, and the other end of the linkage mechanism 33 is formed with a limiting member 331. The relative positions of the second padlock hole 3331 and the limiting member 331 are fixed, and the two ends of the linkage mechanism 33 are in linkage. When the door body 2 is in the closed state, the linkage mechanism 33 is rotated. When the second padlock hole 3331 coincides with the first padlock hole 311, the limiting member 331 is snapped into the locking portion 321 to lock the door body 2 and the cabinet body 1.

[0108] The installation steps of the door lock assembly 3 of the display cabinet are as follows:

[0109] First step, fix the second fixing seat 32 on the top of the outer casing 11 by screws.

[0110] Second step, fix the first fixing seat 31 on the frame at the front of the outer casing 11 by screws.
