Description

Technical Field

[0001] The utility model relates to the field of freezer sliding doors, and particularly to a freezer sliding door seal structure with good sealing performance. Background Art

[0002] A freezer is a professional storage tool for storing various foods that need to be frozen, a small cabinet or chamber for keeping food or other items in a cold state, with an ice maker inside for freezing, a cabinet or box with a refrigeration device, and is widely used in various industries and households. The freezer refrigeration system consists of four basic parts, namely a compressor, a condenser, a throttling component, and an evaporator.

[0003] In order to prevent the cold air in the freezer from escaping, a sealing structure is generally designed on the sliding door of the freezer. The common method is to stick sealing strips on the freezer and the sliding door. However, the contact area between the two sealing strips is small, and the cold air is likely to escape from between the two sealing strips. Moreover, the sliding door collides with the freezer for a long time, resulting in an increase in the gap between the sealing strips, thereby leading to poor sealing effect.

[0004] The Chinese utility model patent with the application number 202022183407.6 proposes a freezer sliding door seal structure with good sealing performance, but there are still some deficiencies:

[0005] 1. Although the seal structure is good, the pressure required for sealing cannot be accurately controlled, and it is impossible to ensure that there is enough force to make the seal block and the sealing strip fit each time. That is, in actual use, it is impossible to clearly know whether the seal block and the sealing strip are closely fitted, or there is a rebound after a strong collision, resulting in a small gap still existing between the sliding door and the cabinet body, leading to poor sealing effect;

[0006] 2. After the seal block and the sealing strip are closely fitted, there is a probability that it is more difficult to pull them apart, that is, the negative pressure makes it more difficult to open the door manually.

[0007] Therefore, the utility model proposes a freezer sliding door seal structure with good sealing performance to solve the above problems. Utility Model Content

[0008] In order to overcome the defects in the above-mentioned prior art, the utility model provides a freezer sliding door seal structure with good sealing performance. Through the locking of the lock rod and the block, the stable sealing between the cabinet body and the sliding door is realized, and the situation of poor sealing effect caused by too small extrusion pressure or difficult manual control of the extrusion pressure will not occur. At the same time, through the first permanent magnet and the second permanent magnet, the simple opening of the sliding door is realized, and the situation of difficult manual door opening caused by negative pressure will not occur, and the opening of the sliding door is also made more convenient.

Detailed implementation manners

[0024] To better illustrate and explain the content of the present utility model, the following is an elaboration in conjunction with the drawings and implementation examples:

[0025] There is Figure 1 - Figure 2 As shown, the present utility model discloses a push - pull door seal structure of a freezer with good sealing performance, including a cabinet body 1 and a push - pull door 2. A sealing block 12 is arranged on the cabinet body 1, and a sealing strip 7 capable of cooperating with the sealing block 12 for sealing is arranged on the push - pull door 2. A gripper 3 is further arranged on the push - pull door 2, and a mating block 4 capable of cooperating with the gripper 3 is arranged on the cabinet body 1. An opening and closing mechanism 900 for ensuring the good sealing of the freezer and facilitating the opening of the push - pull door 2 is arranged between the gripper 3 and the mating block 4.

[0026] Furthermore, the opening and closing mechanism 900 includes a locking slot 21 and a control space 15 arranged on the inner side of the gripper 3 close to the mating block 4. A pressing block 13 hinged to the gripper 3 is slidably arranged in the control space 15, and a first spring 14 is fixedly connected between the pressing block 13 and the inner wall of the control space 15.

[0027] Furthermore, a card slot 17 is arranged on the side wall of the locking slot 21. A clamping block 19 is slidably arranged in the card slot 17. A second spring 18 is fixedly connected between the clamping block 19 and the inner wall of the card slot 17. A traction rope 16 is fixedly connected between the end of the clamping block 19 away from the locking slot 21 and the pressing block 13.

[0028] Furthermore, a locking rod 23 is arranged on the mating block 4. A buffer block 24 is arranged on the locking rod 23, and a mating slot 25 for cooperating with the clamping block 19 is further arranged on the locking rod 23.

[0029] Further, a first permanent magnet 22 is fixedly provided at one end of the lock rod 23 close to the gripper 3, and a second permanent magnet 20 is fixedly provided on a side wall of the locking groove 21 away from the mating block 4. The first permanent magnet 22 repels the second permanent magnet 20.

[0030] Further, a support plate 5 for supporting the sealing block 12 is provided on the cabinet body 1. A first cavity 11 is provided inside the sealing block 12, and a first mounting block 10 is provided outside the sealing block 12.

[0031] Further, an installation space 6 is provided inside the sliding door 2, and the sealing strip 7 is fixedly provided in the installation space 6.

[0032] Further, a second cavity 8 is provided inside the sealing strip 7, and a second mounting block 9 is provided outside the sealing strip 7.

[0033] Specifically, when it is necessary to close the door, the gripper 3 is brought close to the mating block 4, so that the lock rod 23 is inserted into the inside of the locking groove 21. After the lock rod 23 pushes away the latch 19, the latch 19 is inserted into the mating groove 25 under the elastic force of the second spring 18, realizing the locking between the gripper 3 and the mating block 4. At the same time, the distance and extrusion force between the cabinet body 1 and the sliding door 2 are also ensured to be stable, ensuring a good sealing effect.

[0034] When it is necessary to open the door, hold the gripper 3 with one hand and press the pressing block 13, then the traction rope 16 can be pulled, so that the latch 19 is pulled out of the mating groove 25. At this time, the lock rod 23 will move out of the locking groove 21 under the repulsive force between the first permanent magnet 22 and the second permanent magnet 20, realizing unlocking and at the same time being able to drive the sliding door 2 and the cabinet body 1 to separate automatically, avoiding the situation that it is difficult to open manually.
