DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6The utility model provides a technical solution: a refrigeration device with a double-layer sealing structure, including a main body 1, the interior of the main body 1 is hollow, a first fixing plate 2 is fixedly connected to the interior of the main body 1, and second fixing plates 3 are arranged on the upper and lower sides of the first fixing plate 2. The two second fixing plates 3 are respectively fixedly connected to the upper and lower inner walls of the main body 1, and a receiving bucket 4 is arranged between the first fixing plate 2 and the second fixing plate 3. A sliding block 5 is slidably connected to the lower surface of the receiving bucket 4. A circular groove 6 is opened inside the sliding block 5, and the circular groove 6 extends into the bottom wall of the receiving bucket 4. A positioning rod 7 is slidably connected inside the circular groove 6. The lower second fixing plate 3 and the first fixing plate 3 are fixedly connected to the inner wall of the upper and lower sides of the main body 1. The upper surface of each fixed plate 2 is provided with a sliding groove 8, and the sliding block 5 is slidably connected to the inside of the sliding groove 8. The bottom wall of the sliding groove 8 is provided with a positioning groove 9, and the positioning groove 9 is adapted to the positioning rod 7. A first through groove 10 extending from the front side surface is provided in the bottom wall of the accommodating bucket 4, and the first through groove 10 is adapted to the circular groove 6. A connecting plate 11 is slidably connected to the inside of the first through groove 10, and the connecting plate 11 is fixedly connected to the positioning rod 7. The front side surface of the accommodating bucket 4 is fixedly connected with a sealing plate 12, and the rear side surface of the sealing plate 12 is fixedly connected with two first sealing strips 13. The front side surfaces of the first fixed plate 2 and the second fixed plate 3 are both provided with first sealing strips. The first sealing strip 13 and the first sealing groove 14 are adapted to each other. When the staff needs to refrigerate the food in the accommodating bucket 4, the connecting plate 11 is pulled upwards. At this time, the connecting plate 11 will slide inside the first through groove 10. The movement of the connecting plate 11 drives the positioning rod 7 to slide inside the circular groove 6. At this time, the two positioning rods 7 will be separated from the two positioning grooves 9 on the front side. Subsequently, the accommodating bucket 4 is pushed backward. When the position of the sliding block 5 is limited by the sliding groove 8, the positioning rod 7 will be aligned with the rear positioning groove 9. Then the connecting plate 11 is released. At this time, the positioning rod 7 will be stuck in the two rear positioning grooves 9. When the first sealing strip 13 is in the first sealing groove 14, the first sealing strip 13 will enter the first sealing groove 14 and squeeze the first sealing strip 13. The above structure solves the problem of odor contamination in some existing refrigeration equipment during use. The stability of the accommodating bucket 4 is ensured by locking the accommodating bucket 4, avoiding misalignment and gap between the accommodating bucket 4 and the first fixing plate 2, thereby avoiding odor contamination. The accommodating bucket 4 is sealed by the arrangement of the first sealing strip 13 and the first sealing groove 14, thereby further avoiding odor contamination of internal food, improving the refrigeration effect of food, and improving the subsequent taste of food. The refrigeration equipment has high practicality and high sealing performance.

[0030] Furthermore, a second through slot 15 extending to the outside is provided inside the sealing plate 12, and the two connecting plates 11 extend out of the sealing plate 12 through the second through slot 15, and the second through slot 15 is connected to the first through slot 10. The upper surfaces of the two connecting plates 11 are fixedly connected with vertical rods 16, and a cross rod 18 is fixedly connected between the two vertical rods 16. The front side surface of the sealing plate 12 is fixedly connected with a handle 17, and a spring 19 is fixedly connected between the lower surface of the handle 17 and the upper surface of the cross rod 18. When the staff needs to pull out the accommodating bucket 4, by holding the handle 17, the cross rod 18 can be pulled up with the fingers, and the spring 19 will shrink. By lifting the cross rod 18 upward, the two vertical rods 16 are driven to move upward synchronously, so that the two connecting plates 11 slide inside the first through slot 10, and finally the accommodating bucket 4 is locked and unlocked. Through the above structure, the staff can complete the unlocking and locking operations with one hand, reducing the operating steps of the staff and improving the practicality of the device.

[0031] Furthermore, a limiting groove 20 extending from the front side surface is provided inside the right side wall of the main body 1, and a sliding plate 21 is slidably connected inside the limiting groove 20. A groove 22 extending from the front side surface is provided on the right side surface of the sliding plate 21, and a connecting block 23 is provided inside the groove 22. The connecting block 23 is rotatably connected to the inside of the groove 22 through an axis. One end of the connecting block 23 located inside the groove 22 is set as an arc surface, and a sealing door 24 is fixedly connected to the outer surface of the connecting block 23. A motor 25 is fixedly connected to the rear side surface of the main body 1, and the output shaft of the motor 25 rotates and penetrates into the interior of the main body 1. The output shaft of the motor 25 is fixedly connected to a threaded rod 26, and the threaded rod 26 rotates and penetrates into the interior of the limiting groove 20. The sliding plate 21 is threadedly sleeved on the outer surface of the threaded rod 26. The operator starts the motor 25, and the rotation of the threaded rod 26 drives the sliding plate 21 to slide inside the limiting groove 20. After the connecting block 23 is completely located outside the limiting groove 20, the operator can rotate the sealing door 24 to facilitate the subsequent removal of food from the containing bucket 4. After the removal is completed, the threaded rod 26 is reversed by starting the motor 25. At this time, the sliding plate 21 will slide into the inside of the limiting groove 20. At this time, the connecting block 23 will first contact the front side wall of the main body 1, so that the connecting block 23 will slowly rotate inside the groove 22, and the rotation of the connecting block 23 drives the rotation of the sealing door 24. When the sealing door 24 is parallel to the main body 1, the connecting block 23 is completely located inside the limiting groove 20, and the subsequent sliding plate 21 continues to drive the connecting block 23 to move to the rear side.

[0032] Furthermore, a second sealing strip 27 is fixedly connected to a surface of the side of the sealing door 24 facing the main body 1, and a second sealing groove 28 is opened on the front surface of the main body 1, and the second sealing groove 28 and the second sealing strip 27 are adapted to each other. By making the sealing door 24 translate toward one side of the main body 1, the second sealing strip 27 can eventually slide into the interior of the second sealing groove 28 and squeeze the second sealing strip 27, thereby finally achieving the sealing of the sealing door 24 on the main body 1. The sealing performance of the main body 1 is further improved through the above structure, so that the device has a double-layer seal, which effectively avoids the situation where internal odor overflows or insufficient sealing reduces the refrigeration effect, further improves the practicability of the device, and is simple to operate. At the same time, when closing the sealing door 24, no additional operation is required by the staff, thereby reducing the operating steps of the staff.

[0033] Working principle:

[0034] When the refrigeration equipment with a double-layer sealing structure is in use, the connecting plate 11 is pulled upwards, and the connecting plate 11 will slide inside the first through groove 10. The movement of the connecting plate 11 drives the positioning rod 7 to slide inside the circular groove 6. At this time, the two positioning rods 7 will be disengaged from the two front positioning grooves 9, and then the accommodating bucket 4 will be pushed backward. When the position of the sliding block 5 is limited by the sliding groove 8, the positioning rod 7 will be aligned with the rear positioning groove 9, and then the connecting plate 11 will be released. At this time, the positioning rod 7 will be stuck in the inside of the two rear positioning grooves 9, and the first sealing strip 13 will enter the inside of the first sealing groove 14 and squeeze the first sealing strip 13.
