[0006] To achieve the above objectives, the present invention provides the following technical solution: a grain depot door sealing device with heat insulation function, comprising a first protective door and a second protective door, the first protective door being fitted to the left side of the second protective door, an outer frame being provided on the outside of the first and second protective doors, and a heat insulation component being provided at the rear end of the first and second protective doors.
[0007] The heat insulation component includes an insulation layer, which is provided in two sets and respectively attached to the rear ends of the first protective door and the second protective door. Positioning holes are provided through the interior of the four corners of the insulation layer. Mounting blocks are fixedly connected to the four corners of the rear ends of the first and second protective doors. The mounting blocks are inserted into the interior of the positioning holes. Elastic pull straps are fixedly connected to the four corners of the rear ends of the first and second protective doors. The elastic pull straps are inserted and sleeved on the outside of the mounting blocks.
[0008] As a further technical solution of this utility model, a frame is vertically provided on the right side of the rear end of the first protective door and the left side of the rear end of the second protective door, and a heat insulation strip is provided inside the frame.
[0009] As a further technical solution of this utility model, an external base is fixedly connected to the top of the right side of the front end of the first protective door and the top of the left side of the front end of the second protective door, and an auxiliary rod is fixedly connected to the bottom end of the external base.
[0010] As a further technical solution of this utility model, the left side of the front end of the first protective door and the right side of the front end of the second protective door are respectively hinged to the two sides inside the outer frame, the front end of the first protective door is fixedly connected to an extension plate, and the left side of the front end of the second protective door is fixedly connected to an insert plate.
[0011] As a further technical solution of this utility model, an inner groove is provided on the right side of the inner end of the extension plate, and an installation plate is fixedly connected inside the inner groove. The installation plate is inserted into the inside of the insertion plate.
[0012] As a further technical solution of this utility model, the top, bottom and sides of the first protective door and the second protective door are all fixedly connected with sealing edge layers, and the sealing edge layers are in contact with the inner wall of the outer frame.

[0014] As a further technical solution of this utility model, the outer end of the mounting base is recessed inward and has a positioning groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the grain depot door sealing device with heat insulation function not only realizes the heat insulation function and the sealing function, but also realizes the strong connection function.
[0016] By incorporating insulation layers, frames, heat insulation strips, mounting blocks, positioning holes, and elastic straps, two sets of insulation layers are fitted together at the rear ends of the first and second protective doors. The mounting blocks are inserted into the corresponding positioning holes, and the elastic straps are used to pull them outwards and fit around the outside of the mounting blocks, thus limiting and fixing the insulation layers. This optimized connection method facilitates later disassembly and replacement, effectively isolating heat exchange and penetration from the external environment, preventing external temperature differences from affecting the stability of the grain depot's internal temperature, and providing excellent insulation. The addition of heat insulation strips inside the frames reduces the impact of high temperatures on the grain, preventing moisture transfer, condensation, mold, and pest infestation, thus providing a safe and stable storage environment.
[0017] By incorporating a sealing edge layer, insert plate, extension plate, inner groove, and mounting plate, the outer ends of the first and second protective doors utilize the sealing edge layer to enhance their fit with the inner wall of the outer frame, preventing gaps that could reduce the sealing and protective force. Simultaneously, the extension plate is located at the connection between the first and second protective doors, using an interlocking connection method to limit and fix the mounting plate within the insert plate, thereby improving the sealing performance at the connection between the first and second protective doors, effectively isolating external airflow, ensuring food hygiene and safety, and extending the food storage period.
[0018] By incorporating an outer frame, an adhesive outer layer, an outer mounting base, and a positioning groove, the adhesive outer layer added to the contact surface of the outer frame greatly enhances the bonding strength at the joints. The outer mounting base and positioning groove work together to facilitate quick installation while strengthening the connection force at the joints of the outer frame, effectively preventing the outer frame from loosening or falling off during use, and improving the stability and fixation of the outer frame itself.
