[0002] A cold storage facility is a refrigerated building or equipment specifically designed for storing and preserving goods, items, or food in a low-temperature environment. The interior of a cold storage facility is typically kept at a low temperature to slow spoilage or deterioration, especially for perishable items such as fruits, vegetables, meat, seafood, and medicines. The temperature of a cold storage facility can be adjusted according to storage requirements.

[0003] Patent CN 214740296 U discloses a cold storage facility designed to prevent accidental entrapment. The safe room is equipped with a shielding component for opening and closing the containment compartment. A temperature sensing component can detect the indoor temperature. When the temperature sensing component detects that the indoor temperature has dropped to a preset value, an alarm will sound, thereby reminding the staff outside the safe room to provide timely rescue. This reduces the possibility of staff being trapped and causing accidents, thus improving the safety of the cold storage facility.

[0004] While the aforementioned technologies can issue alarms and trigger rescues in a timely manner through alarm components, they cannot issue alarms promptly if the alarm system malfunctions and becomes inoperable. Furthermore, if there is no one on duty in the cold storage or no timely response mechanism, the alarm system cannot solve the actual problems of trapped personnel. Therefore, it has certain limitations, and innovation is needed in this technology. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A cold storage facility designed to prevent accidental entrapment includes a cold storage body 1. A cold storage door 2 is hinged to the front of the cold storage body 1. An anti-entrapment opening is provided in the middle of the bottom of the cold storage door 2. An emergency door 4 is hinged to the bottom of the inner wall of the anti-entrapment opening. Two storage slots 10 are symmetrically provided on the back of the emergency door 4. A sliding plate 12 is slidably connected to the adjacent side of the two storage slots 10. A movable plate 13 is rotatably installed on the non-adjacent end of the two sliding plates 12. By providing an emergency door 4 at the bottom of the cold storage door 2, when trapped inside the cold storage body 1, the emergency door 4 can be opened by removing the latch 9 to release the restriction, thereby escaping through the anti-entrapment opening. Therefore, it can avoid the situation where staff are trapped inside the cold storage and need to wait for rescue. The emergency door 4 provides an emergency exit to ensure that they can escape on their own in case of an emergency.

[0024] In this embodiment, the two sliding plates 12 are the same size, and the two movable plates 13 are the same size. By sliding the movable plate 13 inside the storage slot 10, the movable plate 13 can be moved away from the emergency door 4, and a slope is provided on both sides of the emergency door 4, so as to facilitate the use when transporting goods.

[0025] In this embodiment, sliding grooves 11 are provided on both sides of the inner walls of the two storage slots 10. Slider blocks are slidably connected to the inner walls of the two sliding grooves 11. One end of each set of sliders is fixedly connected to the side of the adjacent slide plate 12. The sliders and sliding grooves 11 are provided to assist the movement and limit the movement of the slide plate 12. Auxiliary grooves are provided on the adjacent sides of the two slide plates 12. Auxiliary plates are slidably connected to the inner walls of the two auxiliary grooves. The auxiliary plates are provided to fill the inner walls of the storage slots 10 during use, so that the top of the emergency door 4 can remain flat when transporting goods.

[0026] In this embodiment, the four corners of the back of the emergency door 4 are provided with grooves 5. The bottom of the inner wall of each of the four grooves 5 is fixedly connected with a contraction spring 6. The top of each of the four contraction springs 6 is fixedly connected with a limit block 7. The outer wall of each of the four limit blocks 7 is slidably connected to the inner wall of the adjacent groove 5. A reinforcing frame 8 is fixedly installed at the bottom of the back of the cold storage body 1. The top and bottom of both sides of the reinforcing frame 8 are connected with pins 9. One end of each of the four pins 9 is movable through the inner wall of the adjacent limit block 7. By stretching the limit block 7 in the groove 5 and passing the pins 9 through the reinforcing frame 8 and the limit block 7, the emergency door 4 can be limited, so that the emergency door 4 remains sealed when closed. When it needs to be opened, the pins 9 can be pulled out. This design is simple to operate and easy to restore, making it convenient for subsequent use.

[0027] In this embodiment, a viewing window 3 is embedded in the top of the front of the cold storage door 2. By setting the viewing window 3 on the cold storage door 2, staff can see the inside situation before entering the cold storage body 1, thus avoiding safety hazards such as accidental entry, collision or being trapped.

[0028] Working principle: When in use, the cold storage door 2 can be opened to enter the cold storage body 1 for work. If frequent and long-term handling of goods is required, the cold storage door 2 can be closed, and the latch 9 on the limit block 7 can be loosened so that the emergency door 4 can be rotated to be perpendicular to the cold storage door 2. The sliding plate 12 slides inside the storage slot 10, which drives the movable plate 13 to slide out of the storage slot 10. The movable plate 13 is pressed against the ground on the corresponding side to provide a slope. Then, the auxiliary plate is stretched at the other end of the sliding plate 12 to fill the top of the emergency door 4 for small goods transportation. If a worker is trapped inside the cold storage body 1 after the cold storage door 2 is closed, he / she can escape from the cold storage body 1 through the anti-trapping opening.
