Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration and freezing equipment, and in particular relates to a horizontal display cabinet with front and rear sliding double doors. Background Technology

[0002] There are two main types of horizontal display cases: left-right sliding double-door horizontal display cases and front-back sliding double-door horizontal display cases. Compared to left-right sliding double-door horizontal display cases, front-back sliding double-door horizontal display cases can meet the needs of multiple people simultaneously retrieving goods from different sections inside the case. However, horizontal display cases typically use baskets to store goods. When restocking, the upper baskets need to be removed to access the lower part of the case. Due to the front-back sliding design of the doors, the top opening of the front-back sliding double-door horizontal display case can only be opened halfway in the front-back direction, making it inconvenient to remove baskets for restocking. Usually, the door needs to be removed to retrieve the baskets, making restocking extremely inconvenient.

[0003] To reduce the workload of disassembling the doors, some double-door horizontal display cases with front and rear sliding doors use a smaller fixed rear door and a larger front sliding door, with the front door on top and the rear door on the bottom. When restocking, the front sliding door can be removed to tilt and remove the baskets. However, this front-on-top, rear-on-bottom installation method makes condensation easily accumulate on the rear door, making cleaning difficult and affecting the product display. If the rear door is on top and the front door on the bottom, although condensation from the rear door can flow to the front door and then drain from the cabinet opening, restocking requires removing the rear door first to remove the front door and retrieve the baskets, resulting in a large amount of disassembly work and inconvenience for restocking. Furthermore, because the rear door is lighter, to prevent it from shifting upwards and coming off during transportation, one end of the rear door is usually inserted into the cabinet opening, while a pressure strip is installed at the center beam to hold down the other end of the rear door, making disassembly of the rear door even more inconvenient.

[0004] To address the inconvenience of restocking double-door horizontal display cabinets with front and rear sliding doors, a triple-door horizontal display cabinet with front and rear sliding doors has been developed. Although using triple-door front and rear sliding doors can increase the opening range of the top opening of the cabinet, thus solving the problem of inconvenience in restocking, the triple-door front and rear sliding doors horizontal display cabinet has a more complex structure and higher cost.

[0005] Therefore, how to provide a horizontal display cabinet with front and rear sliding double doors that is easy to replenish and prevents condensation is a technical problem that urgently needs to be solved. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model provides a horizontal display cabinet with front and rear sliding double doors. It features a design with the rear door on top and the front door on the bottom, which can guide condensation and prevent condensation. Furthermore, it allows for easy disassembly of the doors while ensuring their secure fixation, facilitating restocking.

[0007] This utility model provides a horizontal display cabinet with front and rear sliding double doors, including:

[0008] The cabinet has an opening at the top.

[0009] Cabinet frame assembly, which is installed on the top of the cabinet, includes a frame surrounding an opening at the top of the cabinet and a central crossbeam set in the frame along the front-back direction of the cabinet. The central crossbeam divides the opening surrounded by the frame into multiple cabinet openings arranged in the left-right direction.

[0010] The double-door assembly is installed one-to-one with the cabinet opening to close and open the cabinet opening. The double-door assembly includes a rear door and a front door. The rear door is fixedly installed at the rear of the cabinet opening, and the front door is located below the rear door. The front door slides inside the cabinet opening in the front-back direction.

[0011] The cabinet opening has a first door slide extending in the front-to-back direction on the inner side of the side frame on both the left and right sides, and a second door slide extending in the front-to-back direction on the left and right sides of the middle crossbeam; a slot is opened on the inner side of the side frame, which is close to the rear of the cabinet opening and above the first door slide; and a slot is provided on the left and right sides of the top of the middle crossbeam, which is close to the rear of the cabinet opening and above the second door slide.

[0012] The cabinet openings located at the left and right ends of the cabinet body are called end cabinet openings; the front door installed at the left and right ends of the end cabinet opening has one end placed on the first door slide rail near the end cabinet opening and the other end placed on the second door slide rail near the end cabinet opening, so that the front door can slide along the first door slide rail and the second door slide rail; the rear door installed at the left and right ends of the rear door is inserted into the slot near the end cabinet opening and the other end is engaged in the slot near the end cabinet opening.

[0013] In this technical solution, the double-door assembly adopts a design with the rear door on top and the front door on the bottom. The rear door uses a plug-in and snap-fit ​​installation method, which facilitates disassembly while ensuring the stability of the rear door installation. The front door is placed directly on the first and second door slide rails set on the side frame and the middle crossbeam. The front door can be disassembled simply by lifting it up, making the entire double-door assembly easy to disassemble and convenient for restocking. Moreover, with the rear door on top and the front door on the bottom, condensation can flow naturally from the rear door to the front door, avoiding the problem of condensation accumulation on the rear door and the difficulty in cleaning, thus playing a role in preventing condensation. At the same time, the design with the rear door on top allows items to be placed on the rear door, which helps to improve the user experience.

[0014] In some embodiments, when there are three or more cabinet openings, the cabinet opening located between two end cabinet openings is designated as the central cabinet opening. When a central cabinet opening exists: the left and right ends of the front door installed at the central cabinet opening are respectively placed on two second door slide rails near the left and right sides of the central cabinet opening, allowing the front door to slide along the second door slide rails; the left and right ends of the rear door installed at the central cabinet opening are respectively engaged in two slots near the left and right sides of the central cabinet opening. This technical solution enables convenient installation and removal of the front and rear doors in the central cabinet opening.

[0015] In some embodiments, the top surface and the side facing the cabinet opening of the slot are both open to connect to the cabinet opening from the side. The slot wall opposite the left and right ends of the rear door has engaging protrusions, allowing the end of the rear door to fall into the slot from top to bottom and engage between the engaging protrusions and the bottom surface of the slot. This slot design facilitates the engagement and disengagement of the rear door end, while also improving the stability of the rear door installation.

[0016] In some embodiments, each slot is provided with multiple engaging protrusions to collectively engage the same rear door. This technical solution, by using multiple engaging protrusions to collectively engage the same rear door, ensures the rear door is securely fixed.

[0017] In some embodiments, the rear frame of the door frame has a stepped surface, the rear end of the middle crossbeam overlaps the stepped surface, the rear end of the slot is open, and the rear end of the groove is open, so that the rear end of the rear door is supported on the stepped surface. This technical solution uses the stepped surface to provide stable support for the rear end of the rear door, which helps to improve the stability of the rear door and can also improve the load-bearing capacity of the rear door, so as to facilitate the placement of items on the rear door.

[0018] In some embodiments, the slots and grooves are both angled, with the front lower than the back, so that the rear door is also angled. This technical solution helps condensate to flow naturally from the rear end of the rear door to the front end, and then to the front door, preventing condensate from accumulating on the rear door.

[0019] In some embodiments, the front wall of the slot and the front wall of the card slot abut against the front surface of the rear door to restrict the movement of the rear door in the front-back direction. This technical solution utilizes the front walls of the slot and the card slot to abut against the rear door, thus restricting the movement of the rear door in the front-back direction when the rear door is tilted, ensuring the stability of the rear door installation.

[0020] In some embodiments, both the first and second door slides are inclined at the front and rear, so that the front door is inclined at the front and rear, and a drainage groove is provided on the inner side of the front frame of the opening frame. This technical solution, by making the front door inclined at the front and rear, allows the condensate flowing towards the front door to flow further towards the drainage groove provided on the front frame of the opening frame for discharge.

[0021] In some embodiments, the drainage channel is located below the first and second door tracks, with the front ends of both tracks extending into the drainage channel. This technical solution, by extending the front ends of the first and second door tracks into the drainage channel, facilitates the collection and discharge of condensate in the drainage channel.

[0022] In some embodiments, a drawer mounting opening is provided on the lower front side of the cabinet, and a drawer is installed in the drawer mounting opening, located below the basket placed inside the cabinet. This technical solution uses a drawer to hold goods, and the drawer can be opened to replenish the basket when restocking, further improving the convenience of restocking.

[0023] Based on the above technical solution, the front and rear sliding double-door horizontal display cabinet provided by this utility model adopts a design with the rear door on top and the front door on the bottom. The rear door is installed by plugging and snapping, and the front door is placed directly on the door slide. While ensuring the door is fixed firmly, it realizes convenient disassembly of the door, which is convenient for replenishing the stock. In addition, condensation can flow naturally from the rear door to the front door, avoiding the problem of condensation accumulating on the rear door and being difficult to clean.

The front door 32 can be disassembled simply by lifting it up, making the entire double-door assembly 3 easy to disassemble and convenient for restocking. Moreover, the aforementioned front and rear sliding double-door horizontal display cabinet adopts a design with the rear door 31 on top and the front door 32 on the bottom for its double-door component 3. Condensation can flow naturally from the rear door 31 to the front door 32, avoiding the problem of condensation accumulating on the rear door 31 and being difficult to clean, thus playing a role in preventing condensation. At the same time, the design with the rear door 31 on top allows items to be placed on the rear door 31, which is conducive to improving the user experience.

[0053] In some embodiments, such as Figure 1 and Figure 4As shown, when there are 3 or more cabinet openings a, the cabinet opening a located between the two end cabinet openings a1 is the middle cabinet opening a2; when there is a middle cabinet opening a2: the left and right ends of the front door 32 installed in the middle cabinet opening a2 are respectively placed on the two second door slides 223 near the left and right sides of the middle cabinet opening a2, so that the front door 32 slides along the second door slides 223; the left and right ends of the rear door 31 installed in the middle cabinet opening a2 are respectively engaged in the two slots 221 near the left and right sides of the middle cabinet opening a2. When installing the double-door assembly 3 of the central cabinet opening a2, the installation sequence is the same as that of the end cabinet opening a1; the installation method of the front door 32 located in the central cabinet opening a2 is as follows: the front door 32 is placed directly in the central cabinet opening a2, and when placing it, the two ends of the front door 32 are respectively placed on the two second door slide rails 223 near the left and right sides of the central cabinet opening a2; the installation method of the rear door 31 located in the central cabinet opening a2 is as follows: the rear door 31 is placed from top to bottom, so that the left and right ends of the rear door 31 are respectively locked in the two slots 221 opened in the middle crossbeam 22 near the left and right sides of the central cabinet opening a2. When disassembling the double-door assembly 3 of the middle cabinet opening a2, the disassembly sequence is the same as that of the end cabinet opening a1. The rear door 31 located in the middle cabinet opening a2 is disassembled by lifting the rear door 31 upwards so that the left and right ends of the rear door 31 disengage from the two slots 221, thereby removing the rear door 31 from the cabinet opening a. The front door 32 located in the middle cabinet opening a2 is disassembled by lifting the front door 32 upwards so that the front door 32 disengages from the two second door slide rails 223, thereby removing the front door 32 from the cabinet opening a.

[0054] In some embodiments, such as Figure 3 and Figure 6 As shown, the top surface and the side facing cabinet opening a of the slot 221 are both open to connect to cabinet opening a from the side. The slot wall opposite the left and right end faces of the slot 221 has engaging protrusions 222, allowing the end of the rear door 31 to fall into the slot 221 from top to bottom and be engaged between the engaging protrusions 222 and the bottom surface of the slot 221. This slot 221 design facilitates the engagement and disengagement of the end of the rear door 31, while also improving the stability of the rear door 31 installation. Preferably, each slot 221 has multiple engaging protrusions 222 to jointly engage the same rear door 31. The joint engagement of the rear door 31 by multiple engaging protrusions 222 ensures the secure fixing of the rear door 31.

[0055] In some embodiments, such as Figure 4As shown, the rear frame 212 of the frame 21 has a stepped surface 2121. The rear end of the middle crossbeam 22 overlaps on the stepped surface 2121. The rear end of the slot 221 and the rear end of the groove 2111 are open, so that the rear end of the rear door 31 is supported on the stepped surface 2121. This structural design can use the stepped surface 2121 to provide stable support for the rear end of the rear door 31, which is beneficial to improving the stability of the rear door 31 and the load-bearing capacity of the rear door 31, so as to facilitate the placement of items on the rear door 31.

[0056] In some embodiments, such as Figure 1 and Figure 4 As shown, both the slot 2111 and the card slot 221 are inclined at the front and lower at the back, so that the rear door 31 is also inclined at the front and lower at the back. This arrangement of the slot 2111 and the card slot 221 allows the rear door 31 to be inclined at the front and lower at the back, which helps condensate to flow naturally from the rear end of the rear door 31 to the front end, and then to the front door 32, preventing condensate from accumulating on the rear door 31 and enhancing the anti-condensation effect.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, the front wall of slot 2111 and the front wall of slot 221 abut against the front surface of rear door 31 to restrict the movement of rear door 31 in the front-back direction. By using the front walls of slot 2111 and slot 221 to abut against rear door 31, the movement of rear door 31 in the front-back direction can be restricted when rear door 31 is tilted, ensuring the stability of rear door 31 installation.

[0058] Furthermore, such as Figure 4 , Figures 7-9 As shown, both the first door slide rail 2112 and the second door slide rail 223 are inclined at the front and lower at the back, so that the front door 32 is inclined at the front and lower at the back. The inner side of the front frame 213 of the frame 21 is provided with a drainage groove 2131. By using the first door slide rail 2112 and the second door slide rail 223 that are inclined at the front and lower at the back, the front door 32 can be inclined at the front and lower at the back, so that the condensate flowing into the front door 32 can further flow into the drainage groove 2131 provided in the front frame 213 of the frame 21 for discharge.

[0059] Furthermore, such as Figure 8 and Figure 9 As shown, the drainage channel 2131 is located below the first door slide 2112 and the second door slide 223, with the front ends of both the first door slide 2112 and the second door slide 223 extending into the drainage channel 2131. By extending the front ends of the first door slide 2112 and the second door slide 223 into the drainage channel 2131, it is more conducive to the collection and discharge of condensate in the drainage channel 2131.

[0060] In some embodiments, such as Figure 10 and Figure 11 As shown, a drawer mounting opening 11 is provided on the lower front side of the cabinet 1, and a drawer 4 is installed in the drawer mounting opening 11. The drawer 4 is located below the basket placed inside the cabinet 1. The drawer 4 is used to hold goods, and when restocking, the drawer 4 can be opened to restock the basket, thus achieving restocking without disassembling the door, further improving the convenience of restocking.

[0061] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
