The front side and the left and right side surfaces of the cake cabinet are made of transparent glass plates, which are convenient for customers to see the cakes in the cabinet and make selections. A sliding door is provided at the rear side of the cake cabinet for the seller to put in cakes.

[0003] In the prior art, the sliding door of the cake cabinet is generally connected to the cabinet body of the cake cabinet by an external spring wire. This connection method affects the appearance on the one hand. On the other hand, when the sliding door is manually closed, if it is blocked by the spring wire, the sliding door may not be closed in place, thus affecting the actual refrigeration effect of the freezer, and further causing excessive wear and tear of the equipment, posing a safety hazard.

[0004] In addition, in the prior art, the defogging wire provided on the sliding door is generally electrically connected to an external power supply device through an external wire. The external wire not only affects the appearance, but also may be damaged after excessive bending. Summary of the Utility Model

[0005] The utility model provides a sliding door installation structure of a freezer, aiming to solve the problems mentioned in the above background technique. In the prior art, the sliding door of the cake cabinet is generally connected to the cabinet body of the cake cabinet by a spring wire. This method affects the appearance on the one hand and is prone to wear and tear, posing a safety hazard. At the same time, in the prior art, the defogging wire provided on the sliding door is generally electrically connected to an external power supply device through an external wire. The external wire not only affects the appearance, but also may be damaged after excessive bending.

[0006] The present utility model is realized as follows. An installation structure of a sliding door for a freezer includes: a freezer body with a storage cavity formed therein. An opening communicating with the storage cavity is formed on the side wall of the freezer body. A first slide rail is provided on the inner wall of the opening, and at least one sliding door is slidably connected in the opening. The sliding door is slidably engaged with the first slide rail. A second slide rail is formed along the length of the top wall of the sliding door. Wherein, a nylon drag chain is movably connected in the first slide rail and the second slide rail. The nylon drag chain is bent and its two ends are respectively fixed in the first slide rail and the second slide rail. In this solution, by providing a second slide rail on the top of the sliding door and a first slide rail on the inner side of the opening, the sliding door is slidably arranged in the first slide rail, and the second slide rail is accommodated in the first slide rail. The first slide rail and the second slide rail are connected by a nylon drag chain, and the bent nylon drag chain is hidden inside the first slide rail. On the one hand, it can reduce the area exposed on the outside, reflecting the simplicity and neatness inside the freezer. On the other hand, it will not affect the closing and opening of the sliding door, ensuring the actual refrigeration effect of the freezer and avoiding potential safety hazards.

[0007] In addition, in this device, the wires are hidden in the nylon drag chain. On the one hand, it will not cause excessive bending and wear of the wires, and the flexible nylon drag chain can be used to protect the wires. On the other hand, the wires will not be exposed to the outside, ensuring the overall aesthetics of the device.

[0008] Preferably, the nylon drag chain includes: a chain part and mounting heads fixedly installed at both ends of the chain part. A locking bolt penetrates through each mounting head. Wherein, a mounting seat is fixedly installed on the inner wall of the middle section of the first slide rail. One side of the mounting head abuts against the mounting seat, and the locking bolt is screwed into the mounting seat. The other side of the mounting head is fixedly installed on the inner wall of the second slide rail at the end far from the mounting seat through the locking bolt. In this solution, the nylon drag chain includes a chain part and mounting heads connected to both ends of the chain part. The chain part is arranged in a C shape in the second slide rail, and its upper half extends inside the first slide rail. The mounting seat is arranged at the middle position of the overall length of the opening. One side mounting head is fixedly installed on the mounting seat through a locking bolt, and the other side mounting head is fixedly installed on the inner bottom wall of the second slide rail through a locking bolt.

[0009] It should be explained that when the sliding door is in the closed state, the length of the upper half of the C-shaped nylon drag chain is less than the length of the lower half. Most of the nylon drag chain is stored in the second slide rail. When the sliding door is gradually opened, the length of the upper half of the nylon drag chain gradually increases, and the length of the lower half gradually decreases. Since the nylon drag chain is a flexible structure, its outer shape can be changed according to actual needs, ensuring that the sliding door can be normally opened and closed.

[0010] Preferably, the sliding door further includes: a door frame, the door frame is in a rectangular frame structure, and the second slide rail is provided on the top wall of the door frame, and a transparent glass plate is also embedded in the door frame; in this solution, the sliding door includes a door frame, the door frame is slidably arranged in the first slide rail, the door frame is in a rectangular frame structure, and its interior is a rectangular cavity, and a transparent glass plate is embedded and installed in the rectangular cavity.

[0012] Preferably, the first slide rails are arranged along the length of the inner top wall and the inner bottom wall of the opening, and the top end and the bottom end of the door frame are respectively slidably arranged in the first slide rails; in this solution, two sets of opposite first slide rails are arranged in the opening, which can ensure the stability of the sliding door during the horizontal sliding process, limit the left and right tilting directions of the sliding door, and prevent it from disengaging from the opening.

[0013] Preferably, there are two transparent glass plates, and they are arranged in parallel in the door frame, and there is a gap between the two transparent glass plates; in this solution, setting two transparent glass plates can increase the structural strength of the sliding door, and at the same time, the gap between the two transparent glass plates can prevent the cold air inside the freezer from overflowing. The gap between the two transparent glass plates can play a heat preservation role, improve the refrigeration effect of the freezer, and also facilitate the subsequent assembly of the electric heating wire (defogging wire).

[0014] Preferably, an electric heating wire is also arranged between the two transparent glass plates, the electric heating wire is respectively attached to the two side transparent glass plates, and a wire penetrates through the nylon drag chain. One end of the wire is electrically connected to the electric heating wire, and the other end is electrically connected to an external power supply device; in this solution, an electric heating wire (defogging wire) is installed between the two transparent glass plates. When powered on, it will heat the two transparent glass plates, thereby removing the fog adhering to the transparent glass plates, facilitating manual observation of the internal situation of the freezer. At the same time, the wire is arranged inside the chain part. On the one hand, it can be protected by the nylon drag chain and will not be damaged. On the other hand, it can also reduce the exposure of the wire and improve the overall aesthetics of the freezer.
