DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-5 The utility model is a freezer room escape door, which is arranged on the barracks wall 1 of the freezer room, and includes an external escape door 3, an inner door 4, and a thawing device. The external escape door 3 satisfies the emergency opening function from the inside to the outside in case of an accident, and the inner door 4 is an inner opening door set to enhance the local thermal insulation effect, and at the same time, it satisfies the requirement of opening the thawing line in a short time, so that the inner door can be opened smoothly. As a whole, it realizes the emergency escape function without affecting the refrigeration effect of the freezer room, and has very important promotion and use value.

[0028] The external escape door 3 includes a door body, a door sealing strip 8, an inner spring latch 9, a cold storage lock 10, an outer door hinge 11, an inner emergency push rod 12, and a fastening screw 13. The door body adopts the same insulation material as the wall (red electrostatic color steel plate on the outside and white color steel plate mask on the inside), and a spring latch is set at the upper right corner of the rear of the door to add a locking function during transportation in the freezer. The external escape door 3 is installed on the barracks wall 1 of the freezer room through the external door hinge 11. Once a person is trapped in the freezer room by accident, he can hit the emergency push rod 12 on the inside of the door on one side of the room to push the external cold storage lock 10 to open, so as to realize the emergency escape function. It also includes a hinged plate, one side of which is hinged to the barracks wall 1 of the freezer room, and the other side of which is connected to the door body through a fastening screw 13.

[0029] Installation of the inner door 4: The inner door 4 uses a tongue-and-groove method to seal the end side of the inner door frame 19, and the inner door 4 and the inner door frame are sealed with an inner rubber pad 5 (EPDM rubber); the fixing screws 6 connect the inner door frame 19 and the embedded parts 2 (located inside the barracks wall 1), and the sealant 7 is filled between the inner door frame 19 and the indoor panel layer to enhance the sealing and thermal insulation performance; a thaw layer 14 is arranged around the inner side of the inner door frame 19; the thermal insulation material of the inner door 4 is the same as that of the external escape door 3, the difference is that the panels on both sides are made of 304 stainless steel plates, and the inner door is provided with a handle 17 and an inner door hinge 16 on the indoor side, both of which are made of 304 stainless steel. The main function of the inner door 4 is to enhance the thermal insulation effect at the door, and prevent the local thermal insulation effect of the freezer room from being reduced due to the installation of the escape door. The door cover is provided with a thawing layer 14 so that after the internal heating power switch 18 is turned on, the ice layer on the inner side of the inner door can be quickly melted, so that the inner door can be quickly opened and then the outer door can be knocked open to realize emergency escape.

[0030] The thawing layer 14 of the inner door 4 adopts an aluminum alloy U-shaped buckle groove, and a heating cable 15 is installed inside. It is controlled by a heating power switch 18 arranged on the outside of the top of the inner door to achieve rapid heating and melting of the ice layer inside the inner door, thereby achieving rapid opening of the inner door 4.
