Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, and in particular to a cold storage door with an easy-to-replace sealing strip. Background Technology

[0002] Cold storage facilities are specialized refrigeration systems that artificially regulate temperature and humidity, primarily used for the constant-temperature storage of food, chemical raw materials, and pharmaceutical products. Compared to household refrigerators, cold storage facilities offer significantly larger refrigeration spaces, but their operating principles are similar. These facilities are typically built near logistics ports or the product's place of origin to ensure efficient storage and transportation. As a critical component of cold storage, the doors must meet stringent requirements for insulation, sealing, and fire resistance.

[0003] Currently, cold storage doors commonly use sealing strips for sealing, but this method has significant drawbacks: after long-term use, the sealing strips are prone to aging and yellowing, leading to a decrease in sealing performance and causing cold air leakage. Furthermore, replacing the sealing strips is a cumbersome process, requiring considerable manpower for disassembly and maintenance.

[0004] In view of this, the inventors hoped to design a cold storage door with easy-to-replace sealing strips, which could reduce the labor costs required for disassembly and maintenance. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a cold storage door with a sealing strip that is easy to replace.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A cold storage door with easily replaceable sealing strips includes a sliding door body, a gear, and a sealing strip;

[0008] The actuating gear consists of a gear part and a positioning shaft that is fixed inside it. The positioning shaft has a hexagonal groove opened inward at one end near the inner area of ​​the cold storage.

[0009] The sealing strip is composed of a first strip and a second strip. The width of the first strip is greater than the width of the second strip. The inner side of the first strip is evenly distributed with tooth grooves that mate with the gear.

[0010] The outer side of the sliding door body is provided with a sealing strip mounting groove for easy installation of a sealing strip. The inner side of the sliding door body is provided with a plurality of actuating gear mounting grooves for easy installation of actuating gears. The inner side of the sliding door body is provided with a wrench operating groove for easy exposure of a hexagonal groove.

[0011] Furthermore, in the aforementioned cold storage door with easily replaceable sealing strips, the axial thickness of the actuating gear as a whole is less than the thickness of the sliding door body.

[0012] Furthermore, in the aforementioned cold storage door that facilitates the replacement of sealing strips, the sliding door body is provided with a rounded corner structure at the corner point to facilitate the turning of the sealing strip, and a gear is installed at the axis of the circle where the rounded corner structure is located; the cold storage door frame is provided with an arc-shaped sealing part at the corner point that cooperates with the rounded corner structure.

[0013] Furthermore, in the aforementioned cold storage door that facilitates the replacement of sealing strips, the cross-section of the sealing strip mounting groove is a T-shaped anti-detachment structure with a wider inner side and a narrower outer side. The depth of the sealing strip mounting groove is less than the overall thickness of the sealing strip, and the second strip portion of the sealing strip protrudes outward relative to the sliding door body.

[0014] Furthermore, in the aforementioned cold storage door that facilitates the replacement of sealing strips, the diameter of the wrench operating groove is smaller than the outer diameter of the positioning shaft.

[0015] Furthermore, in the aforementioned cold storage door with easily replaceable sealing strips, the sealing strip is made of EPDM rubber, which is suitable for low-temperature environments.

[0016] The beneficial effects of this utility model are:

[0017] This utility model features a reasonable structural design. A sealing strip mounting groove is formed on the outer side of the sliding door body, extending inwards. Multiple actuating gear mounting grooves are spaced apart on the inner side of the sealing strip mounting groove, with actuating gears pre-installed in these grooves. A wrench operating groove is provided on the inner side of the sliding door body to expose the hexagonal grooves. When the sealing strip needs to be replaced, an electric Allen wrench is used to drive the actuating gears near the outlet area of ​​the sealing strip mounting groove, allowing the old sealing strip to be quickly pulled out. Then, by using the electric Allen wrench to drive each actuating gear one by one, a new sealing strip inserted through the inlet of the sealing strip mounting groove can be quickly filled into the groove. This convenient operation reduces the labor costs required for disassembly and maintenance.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description
