Description

Technical Field

[0001] This utility model relates to the field of cold storage explosion-proof door technology, and in particular to a cold storage explosion-proof door for storing chemicals. Background Technology

[0002] An explosion-proof door for cold storage of chemicals is a special door specifically designed for cold storage of chemicals. Its main functions are, under normal circumstances, to serve as the entrance and exit of the cold storage, ensuring the airtightness of the cold storage, maintaining the internal low-temperature environment, preventing the entry of external heat, moisture, and dust, and preventing the leakage of chemicals from the cold storage to the outside. In the event of an explosion or other dangerous situation, it can effectively prevent the shock wave, flames, and high-temperature gases generated by the explosion from spreading to the outside of the cold storage, protecting the safety of personnel, facilities, and the environment around the cold storage.

[0003] Currently, existing cold storage explosion-proof doors are manually opened and equipped with specialized high-strength explosion-proof locks. To open, workers insert a key into the lock cylinder and rotate it to activate the internal mechanical mechanism, thus unlocking the door. However, over time, the internal mechanical mechanism wears down due to frequent key insertions and rotations. For example, the pins inside the lock cylinder may lose precision due to prolonged friction, leading to difficulty in key insertion and proper retraction of the bolt. This prevents workers from opening the door promptly and smoothly. Existing technology addresses this by implementing a sealing design for the lock cylinder. To prevent dust, moisture, and chemical gases from entering the lock cylinder, a protective coating, such as Teflon, is applied to the surface of the lock cylinder. This coating has good corrosion resistance and a low coefficient of friction, which can further protect the internal mechanical components of the lock cylinder from external environmental factors. However, although Teflon coating has many excellent properties, it will gradually peel off and wear down during long-term use, especially under frequent key insertion and removal and external friction. Once the coating peels off, the metal surface of the lock cylinder will be exposed. Without the protection of the coating, it is susceptible to corrosion and wear, which will cause inconvenience to opening and closing the lock cylinder door. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cold storage explosion-proof door for storing chemicals, aiming to improve the problem in the prior art where the coating gradually peels off and wears, causing corrosion and wear to the lock cylinder, which makes opening and closing the door inconvenient.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cold storage explosion-proof door for storing chemicals, comprising a chamber body, an elongated hollow plate fixedly connected to the front side of the outer wall of the chamber body, an inner sliding groove long block fixedly connected to the top rear side of the elongated hollow plate, a second motor fixedly connected to the top right side of the elongated hollow plate, a second gear fixedly connected to the output end of the second motor, a chain installed on the outer wall of the second gear, a first gear rotatably connected to the front side of the outer wall of the inner sliding groove long block, the first gear and the second gear being connected by chain transmission, an L-shaped plate fixedly connected to the outer wall of the chain, a grooved long block fixedly connected to the front side of the outer wall of the chamber body, a movable door slidably connected inside the grooved long block, the top of the movable door being fixedly connected to the bottom of the L-shaped plate, and a moving mechanism installed inside the chamber body, the moving mechanism being used to evenly disperse the air in the cold storage into the interior of the cold storage for diffusion.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the sliding door is threaded with a screw two, and the outer wall of the screw two is threaded with a warning sign.

[0012] As a further description of the above technical solution:

[0013] The bottom of the sliding door is fixedly connected with multiple pulleys at equal intervals.

[0014] As a further description of the above technical solution:

[0015] A hollow box is fixedly connected to the front side of the outer wall of the room, and a drawer is slidably connected inside the hollow box.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by turning on the second motor, the second gear fixedly connected to the output end is driven to rotate. When the second gear rotates, it drives the first gear on the front side of the inner sliding block to rotate synchronously through the chain on the outer wall. Finally, through the L-shaped plate on the outer wall of the chain, the movable door inside the grooved long block is opened and closed. This avoids the problem of inconvenience caused by the gradual peeling and wear of the coating, which leads to corrosion and wear of the lock cylinder, making it difficult to open and close the vault door.
