[0034] 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.

[0035] Please see Figures 1-8 The present invention provides the following technical solution:

[0036] Example 1: An energy-saving sealing structure for a cold storage door, comprising a cold storage wall 1, multiple heating wires 5 embedded in the wall of the cold storage wall 1, a door groove structure 2 provided in the cold storage wall 1, a first cold storage door 3 and a second cold storage door 4 installed in the door groove structure 2, an exhaust hole 7 opened in the first cold storage door 3, a sealing component 8 installed in the exhaust hole 7, and a vacuum structure 6 provided at the front end of the outer side of the cold storage wall 1;

[0037] Figures 1-4 and Figures 6-8 As shown, the door groove structure 2 includes a first groove frame 201, a first sealing strip 202, a second groove frame 203, and a second sealing strip 204. The first groove frame 201 is opened at the front and rear ends inside the cold storage wall 1, and the second groove frame 203 is opened at the middle of the cold storage wall 1. The first sealing strip 202 is fixedly installed inside the first groove frame 201, and the second sealing strip 204 is fixedly installed inside the second groove frame 203. The first cold storage door 3 includes a first door body 301, a third sealing strip 302, and a fourth sealing strip 303. The second cold storage door 4 includes a second door body 401 and a fifth sealing strip 402. The third sealing strip 302 is fixedly installed at one end of the first door body 301, and the fourth sealing strip 303 is fixedly installed inside the wall of the first door body 301 away from the third sealing strip 302. The fifth sealing strip 402 is fixedly installed inside both the front and rear walls of the second door body 401.

[0038] Both the frame and the door body are equipped with sealing strips. The multiple sealing strips improve the sealing performance of the sealing structure. The inner first door body 301 can be made of stainless steel or corrosion-resistant aluminum alloy, which is resistant to low temperatures and rust, making it suitable for high humidity environments, and its surface is easy to clean. The middle second door body 401 can be made of rigid polyurethane (PU) foam material, which has good thermal insulation performance, preventing cold air from escaping and hot air from entering, thereby reducing energy consumption. The outer first door body 301 can be made of stainless steel or fiberglass. Stainless steel is corrosion-resistant, which can improve its service life. Fiberglass (FRP) is lightweight and has strong weather resistance, making it suitable for outdoor cold storage and also improving its service life.

[0039] The first door body 301 at the front and rear ends is rotatably connected in the first groove frame 201, and the second door body 401 is slidably connected in the second groove frame 203. To open the first cold storage door 3, first hold the handle of the outer first door body 301 to open the outer first door body 301, then hold the second door body 401 and slide the second door body 401 to open it, and finally hold the inner first door body 301 to open the sealing structure completely.

[0040] like Figures 1-3 and Figure 6As shown, the vacuum structure 6 includes a vacuum pump 601, an extraction pipe 602, an outlet pipe 603, and a piezoresistive sensor 604. Multiple piezoresistive sensors 604 are fixed on the top and bottom walls of the cold storage wall 1. The piezoresistive sensors 604 detect the vacuum level between the front and rear first door bodies 301. An extraction hole 7 is opened in the outer first door body 301. The extraction pipe 602 is inserted into the extraction hole 7, and the vacuum pump 601 is turned on to extract the air inside. The air is discharged from the outlet pipe 603. When the piezoresistive sensor 604 reaches the design value, the vacuum pump 601 automatically shuts off. Finally, the extraction pipe 602 can be pulled out directly.

[0041] like Figure 4 and Figure 5 As shown, the sealing assembly 8 includes a silicone sealing valve 801 and a sealing plug 802. The silicone sealing valve 801 is fixedly installed in the air extraction hole 7. When the silicone sealing valve 801 is squeezed by external force, it can open automatically and the air extraction tube 602 can be inserted into it to improve the air tightness between the air extraction tube 602 and the air extraction hole 7. When the air extraction tube 602 is pulled out, the silicone sealing valve 801 automatically closes to prevent outside air from entering. At the same time, the sealing plug 802 is inserted into the air extraction hole 7 to further improve the sealing performance.

[0042] like Figure 2 , Figure 3 and Figure 8 As shown, multiple heating wires 5 are embedded in the wall of the cold storage 1. The heating wires 5 can heat the second groove frame 203 and the second sealing strip 204 to prevent the second groove frame 203 and the second sealing strip 204 from frosting and freezing, which would affect the seal.
