[0051] As a specific embodiment of the present application, the sliding device comprises:

[0052] The T-shaped groove 12 is provided with a plurality of T-shaped grooves, which are horizontally arranged on the side wall of the refrigeration chamber 11 and are arranged in an up-down uniform manner.

[0053] Connecting plate 33: the connecting plate 33 is fixed to the side plate 31 of the sliding frame 3 on the side facing the T-shaped groove 12, and each T-shaped groove 12 is provided with a connecting plate 33 on the side plate 31 at the horizontal position;

[0054] Pulley 35: a plurality of T-shaped grooves 12 are provided with a plurality of pulleys 35, and the number of pulleys 35 in each T-shaped groove 12 is equal;

[0055] Connecting shaft 34: the middle part of each pulley 35 is rotatably connected to one end of a connecting shaft 34, and the other end of the connecting shaft 34 extends out of the T-shaped groove 12 and is fixedly connected to the connecting plate 33.

[0056] In the present application, the sliding device is used to slidably connect the sliding frame 3 and the cabinet body 1, wherein a transverse T-shaped groove 12 is formed in the side wall of the refrigeration chamber 11, a plurality of pulleys 35 are arranged in the T-shaped groove 12, the pulleys 35 can roll in the T-shaped groove 12 but cannot move laterally, the middle part of one side of the pulley 35 is rotatably connected to the connecting shaft 34, the connecting shaft 34 extends out of the end of the T-shaped groove 12 and is fixedly connected to one side of the connecting plate 33, and the connecting plate 33 is further fixed to the side plate 31, thereby being integrated with the sliding frame 3. When the sliding frame 3 moves along the direction of the T-shaped groove 12, the pulley 35 is driven to roll in the T-shaped groove 12, thereby realizing the sliding of the sliding frame 3 and the door body fixed at the end thereof relative to the cabinet body 1. Since the pulley 35 cannot be separated from the T-shaped groove 12 from the side, the weight of the sliding frame 3 and the cabinet door 2 is transmitted to the T-shaped groove 12 and the side wall of the cabinet body 1 through the connecting plate 33, the connecting shaft 34 and the pulley 35, thereby supporting and limiting the sliding frame 3 and the door body. The sliding direction of the sliding frame 3 and the cabinet door 2 is always parallel to the T-shaped groove 12, thereby avoiding the lateral deviation of the sliding frame 3 and the cabinet door 2 during movement, thereby avoiding the friction between the sliding frame 3 and the inner wall of the refrigeration chamber 11, and thereby avoiding the damage of the cabinet body 1. In order to make the support of the T-shaped groove 12 to the sliding frame 3 and the door body more reliable, a plurality of identical T-shaped grooves 12 are arranged in the present application, which are uniformly arranged above and below each other, thereby transmitting the weight of the sliding frame 3 and the door body to the cabinet body 1 at multiple points, reducing the bearing pressure of each other, reducing the normal pressure of the pulley 35 and the T-shaped groove 12, thereby reducing the lateral friction of the pulley 35 during sliding, and making the whole structure more stable and smoother during sliding.

[0057] As a specific embodiment of the present application, the cabinet door 2 is rotatably connected with a roller 22, and the lowest point of the roller 22 is at the same horizontal position as the bottom surface of the cabinet body 1.

[0058] When the cabinet door 2 slides outward, if the bottom edge is flush with the bottom surface of the cabinet body 1, the bottom of the cabinet door 2 may be damaged by friction with the ground, and the outward movement of the cabinet door 2 is hindered. In the present application, the bottom of the cabinet door 2 is higher than the bottom surface of the cabinet body 1, and a roller 22 is installed. The roller 22 is rotatably connected to the protruding rotating seat of the bottom edge of the cabinet door 2, and the lowest point is flush with the bottom surface of the cabinet body 1. When the cabinet door 2 is pulled to slide, the roller 22 rolls on the ground, which not only reduces the frictional resistance of the cabinet door 2 during sliding and protects the bottom of the cabinet door 2, but also supports the cabinet door 2 and the sliding frame 3 connected to the cabinet door 2. The weight of the cabinet door 2 and the sliding frame 3 is directly transmitted to the ground, reducing the load pressure of the sliding device and the friction during sliding, making the opening and closing of the cabinet door 2 more smooth.

[0059] As a specific embodiment of the present application, the bottom plate 32 of the sliding frame 3 protrudes downward on one side to form a limiting block 36, and the bottom of the refrigeration chamber 11 is provided with a sliding limiting groove 13, and the limiting block 36 is located inside the sliding limiting groove 13.

[0060] In order to prevent the sliding frame 3 from sliding too far outward when the cabinet door 2 is pulled to slide, causing the pulley 35 to disengage from the T-shaped groove 12 and causing the sliding frame 3 to fall off, the bottom of the sliding frame 3 is designed to protrude downward on one side to form a limiting block 36, and a sliding limiting groove 13 is formed in the bottom of the refrigeration chamber 11 directly below the limiting block 36, and the limiting block 36 is located inside the sliding limiting groove 13. There is a certain distance between the top end of the side of the sliding limiting groove 13 and the top end of the side of the cabinet body 1. When the limiting block 36 slides to the side with the sliding frame 3, it will be stopped at the top end of the side of the sliding limiting groove 13 and cannot continue to slide, thereby limiting the sliding distance of the sliding frame 3. The sliding limiting groove 13 is parallel to the T-shaped groove 12, which can further limit the movement direction of the sliding frame 3 and prevent it from deviating to the side.

[0061] As a specific embodiment of the present application, the cabinet door 2 is provided with a gas pressure balancing device, which comprises:

[0062] The movable cavity 23 is formed in one side of the cabinet door 2;

[0063] The movable slot 24 is formed in one side of the movable cavity 23, and one side of the movable slot 24 is connected to the movable cavity 23, and the other side is connected to the outside;

[0064] The communication hole 25 is formed in the side of the cabinet door 2 facing the cabinet body 1, and the refrigeration chamber 11 and the movable cavity 23 are communicated;

[0065] The movable block 26 is provided in the movable cavity 23, and can slide up and down along the movable cavity 23. The side of the movable block 26 facing the communication hole 25 is made of rubber and blocks the communication hole 25.

[0066] Reset spring 27: The reset spring 27 is located at the bottom of the movable block 26 inside the movable cavity 23. Its upper end is fixedly connected to the movable block 26, and its lower end is fixedly connected to the bottom wall of the movable cavity 23.

[0067] Push rod 28: The push rod 28 is located inside the movable groove 24. One end of it extends into the movable cavity 23 and is fixedly connected to one side of the movable block 26, while the other end extends out of the movable groove 24 and is exposed to the outside.

[0068] When the freezer is refrigerating its interior, the internal air temperature decreases and its volume contracts, resulting in an internal air pressure lower than the external air pressure. When the door seal 21 is well-sealed, this can make it difficult to open the door 2. To easily open the door 2 when there is a large pressure difference between the inside and outside of the freezer, this invention incorporates a pressure balancing device. A movable cavity 23 is formed inside the door 2. A connecting hole 25 is formed on the surface of the door 2 facing the refrigerator compartment 11, connecting the upper part of the movable cavity 23. A movable groove 24 is formed on the side of the movable cavity 23, connecting it to the outside. Under normal conditions, a movable block 26 inside the movable cavity 23, under the elastic force of its bottom return spring 27, presses against the upper end of the movable cavity 23, and its side blocks the connecting hole 25. Because the side of the movable block 26 is made of rubber, it has good elasticity and... The airtightness effectively seals the connecting hole 25, minimizing its impact on the overall sealing of the cabinet door 2. A push rod 28, extending through the movable groove 24 and reaching the outside, is fixed to one side of the movable block 26. When the cabinet door 2 is difficult to open due to the pressure difference between the inside and outside of the cabinet 1, simply hold the push rod 28 and push it downwards to drive the movable block 26 downwards. After the movable block 26 moves downwards a certain distance below the horizontal position of the connecting hole 25, the connecting hole 25, the movable cavity 23, and the movable groove 24 become interconnected, connecting the refrigerator compartment 11 with the outside air. The outside air will enter the refrigerator compartment 11 to balance the pressure difference between the inside and outside, thus reducing the resistance to opening the cabinet door 2. After opening the cabinet door 2, release the push rod 28, and the movable block 26, under the force of the return spring 27 at its bottom, will move upwards together with the push rod 28, re-blocking the connecting hole 25 and completing the reset.

[0069] As a specific embodiment of the present invention, the side plate 31 of the sliding frame 3 has multiple arc-shaped long grooves 37. Each arc-shaped long groove 37 is provided with a support block 38 below it, and it is fixedly connected to the surface of the side plate 31. Each support block 38 is provided with a support plate 4 above it. The edge of the support plate 4 facing the side plate 31 is an arc-shaped edge 41, which is located inside the arc-shaped long groove 37.

[0070] In order to enable the refrigerated goods on the slide frame 3 to be placed in layers and the personnel to distribute the space in the refrigeration chamber 11, a plurality of arc-shaped long grooves 37 are formed on the side plate 31 of the slide frame 3, and a support block 38 fixed to the side plate 31 is arranged below each arc-shaped long groove 37. The space on the slide frame 3 is divided by installing a support plate 4 on the side plate 31. The plate edge of the support plate 4 is an arc-shaped edge 41. When the support plate 4 is installed, first, the support plate 4 is parallel to the side plate 31, and the arc-shaped edge 41 is aligned downward to the entrance of the arc-shaped long groove 37. Then, the support plate 4 is turned downward by 90°, so that the arc-shaped edge 41 is inserted into the arc-shaped long groove 37, and the bottom surface of the support plate 4 and the top of the support block 38 are mutually attached to form a fulcrum. The end of the support plate 4 away from the side plate 31 has a downward turning tendency around the contact point of the support plate 4 and the support block 38 under the action of its own gravity, and the arc-shaped edge 41 is limited in the arc-shaped long groove 37 and cannot move upward, so the posture of the support plate 4 is fixed at this time. When the support plate 4 is to be removed, only the side of the support plate 4 away from the side plate 31 is turned upward by 90°. During the turning process, the arc-shaped edge 41 exits the arc-shaped long groove 37, so that the support plate 4 can be taken out. Through the simple disassembly and loading of the support plate 4, the space on the side of the slide frame 3 can be reasonably distributed, and the goods are placed on the support frame for classification, which is convenient for personnel to take.

[0071] As a specific embodiment of the present application, the movable slot 24 on the side of the cabinet door 2 is fixedly connected with a handle 29 above.

[0072] In order to facilitate the personnel to exert a pulling force on the cabinet door 2 on the side of the cabinet door 2, a ring-shaped handle 29 is fixedly installed on the side of the cabinet door 2. The personnel can hold the handle 29 to exert a lateral force on the door to slide the cabinet door 2.

[0073] As a specific embodiment of the present application, the surface material of the side wall inside the sliding limiting groove 13 opposite to the side surface and the bottom surface of the cabinet door 2 in the refrigeration chamber 11 is polyurethane.

[0074] In order to prevent the personnel from exerting too much force when opening and closing the cabinet door 2, causing the slide frame 3 and the side wall inside the sliding limiting groove 13 opposite to the side surface and the bottom surface of the cabinet door 2 to collide with the limiting block 36 and the top side wall of the sliding limiting groove 13, causing damage to the machine body, the material of the side wall inside the sliding limiting groove 13 opposite to the side surface and the bottom surface of the cabinet door 2 is limited to polyurethane, which has good elasticity and serves as a kind of buffer material to play a role in shock absorption and buffering in the collision, protecting the machine parts.

[0075] As a specific embodiment of the present application, the support plate 4 has a net-like hollow structure on the surface of the plate body.

[0076] When multiple support plates 4 are installed on the side plate 31, in order to prevent them from hindering the circulation of cold air inside the refrigeration chamber 11, the support plate 4 of the present application has a surface with a meshed hollow structure, which can support the articles without hindering the up-and-down movement of the cold air in the refrigeration chamber 11, and the meshed hollow structure reduces the weight of the support plate 4 itself, reducing the load-bearing burden of the side sliding device and the side of the cabinet 1.

[0077] As a specific embodiment of the present application, a rubber strip 5 is wrapped and fixed on the bottom edge of the cabinet door 2.

[0078] At the moment when a person stands on one side and opens the cabinet door 2, if the person's feet are too far forward, they may be scratched by the relatively sharp corners at the bottom of the cabinet door 2. In the present application, a rubber strip 5 is wrapped and fixed on the bottom edge of the cabinet door 2, which can wrap the corners at the bottom of the cabinet door 2, and when the cabinet door 2 collides with the feet, it plays a buffering role, improving the safety factor of the cabinet door 2.
