The left side of the front side of the cold storage side panel 1 is movably connected with a labor-saving mechanism 9 through an axle pin, both sides of the inner side of the electromagnet 5 are fixedly connected with reinforcement components 10, and the right side of the front side of the cold storage side panel 1 is fixedly connected with an emergency switch 11, and the emergency switch 11 is electrically connected to the electromagnet 5 through a wire.

[0023] refer to Figure 1 The labor-saving mechanism 9 includes a movable seat 91, the back of which is movably connected to the left side of the front face of the cold storage side panel 1 through an axle pin, a lever 92 is provided on the front face of the movable seat 91, the interior of the movable seat 91 is movably connected to the right side of the surface of the lever 92 through an axle pin, a transmission member 93 is fixedly connected to the right side of the lever 92, and a push plate 94 is fixedly connected to the right side of the inner side of the transmission member 93.

[0024] As a technical optimization scheme of the utility model, by setting up a labor-saving mechanism 9, when the user is frozen in the gap between the cold storage door body 2 and the cold storage side panel 1, the trapped person can hold the leftmost side of the lever 92 and pull it toward the front, and then the rightmost side of the lever 92 will drive the transmission member 93 to move backward, and then the transmission member 93 will drive the push plate 94 to move backward. At this time, the principle of the lever 92 "when the power arm is greater than the resistance arm, a smaller force is required to push a larger weight" is used to enable the trapped person to open the frozen cold storage door body 2 in a more labor-saving way.

[0025] refer to Figure 2The reinforcement assembly 10 includes a reinforcement rod 101, the outer side of the reinforcement rod 101 is fixedly connected to the two sides of the inner side of the electromagnet 5, and reinforcement grooves 102 are provided on both sides of the outer side of the iron block 4, and the reinforcement rod 101 is plugged into the reinforcement grooves 102.

[0026] As a technical optimization scheme of the utility model, by setting a reinforcement component 10, the user can drive the reinforcement rod 101 to move inward when starting the adsorption of the electromagnet 5 and the iron block 4, and then the reinforcement rod 101 will be inserted into the reinforcement groove 102 accordingly to reinforce the connection between the electromagnet 5 and the iron block 4, thereby further improving the firmness of the cold storage door body 2 during normal use.

[0027] refer to Figure 3 The left side of the lever 92 is fixedly connected with an electric heating rod 12 , the surface of the electric heating rod 12 is sleeved with a metal heat-conducting rod 13 , and the right side of the metal heat-conducting rod 13 is welded to the left side of the lever 92 .

[0028] As a technical optimization scheme of the utility model, by setting an electric heating rod 12 and a metal heat-conducting rod 13, before the trapped person needs to use the lever 92, the electric heating rod 12 is in an open state for a long time and maintains a certain constant temperature. Then, when the trapped person uses the lever 92, he or she can hold the metal heat-conducting rod 13 heated by the electric heating rod 12 to apply force to the lever 92, thereby preventing the surface temperature of the lever 92 from being lowered under the influence of the temperature in the cold storage, causing the trapped person to get frostbite on his or her hands and be unable to apply force to the lever 92 when using the lever 92.

[0029] refer to Figure 3 The surface of the metal heat-conducting rod 13 is covered with a heat-insulating sleeve 14 , and the inner wall of the heat-insulating sleeve 14 is slidably connected to the surface of the metal heat-conducting rod 13 .

When the trapped person needs to hold the metal heat conducting rod 13 to apply force, the user can directly pull the heat insulating sleeve 14 off to the left, and then the metal heat conducting rod 13 can be used.

[0031] refer to Figure 3 The right sides of both sides of the heat insulation sleeve 14 are fixedly connected with the first Velcro 15 , the right side of the first Velcro 15 is pasted with the second Velcro 16 , and the right side of the second Velcro 16 is fixedly connected with the two sides of the left side of the lever 92 .

[0032] As a technical optimization solution of the utility model, by setting the first Velcro 15 and the second Velcro 16, the thermal insulation sleeve 14 can be installed by directly pasting the first Velcro 15 and the corresponding second Velcro 16, so that the thermal insulation sleeve 14 can be installed, which can not only prevent the thermal insulation sleeve 14 from falling off but also does not affect the trapped persons to get off the thermal insulation sleeve 14.

[0033] refer to Figure 3 A gusset plate 17 is fixedly connected to the right side of the top of the heat insulation sleeve 14, and the material of the gusset plate 17 is PP plastic.

[0034] As a technical optimization solution of the utility model, by providing a buckle plate 17, when the user needs to tear off the insulation sleeve 14, the user can apply force to the insulation sleeve 14 by buckling the buckle plate 17, thereby providing the user with a point of force for applying force, and utilizing the advantage of the low cost of PP plastic to reduce the cost of use.

[0035] The working principle and use process of the utility model are as follows: when a person is mistakenly locked in the cold storage, the user who is mistakenly locked can press the emergency switch 11 to close the electromagnet 5 and no longer magnetically adsorb with the iron block 4, and then use the tension of the tension spring 8 to pull the electromagnet 5 outward, so that the electromagnet 5 moves to the inside of the movable groove 3. At this time, the cold storage door body 2 is no longer fixed, and then the trapped person can open the cold storage door body 2. If the gap between the cold storage door body 2 and the cold storage side plate 1 is frozen, the trapped person can hold the leftmost side of the lever 92 and pull it toward the front, and then the rightmost side of the lever 92 will drive the transmission member 93 to move backward, and then the transmission member 93 will drive the push plate 94 to move backward. At this time, the principle of the lever 92 "when the power arm is greater than the resistance arm, a smaller force is required to push a larger weight" is used to enable the trapped person to open the frozen cold storage door body 2 in a more labor-saving way, and have the ability to escape in an emergency.

[0036] To sum up: the cold storage door with emergency escape device is provided with an emergency switch 11. The emergency switch 11 is pressed, so that the electromagnet 5 is closed and no longer magnetically adsorbed with the iron block 4. Then, the tension of the tension spring 8 is used to pull the electromagnet 5 outward, so that the electromagnet 5 moves to the inside of the movable groove 3. At this time, the cold storage door body 2 is no longer fixed, and then the trapped person can open the cold storage door body 2, which solves the problem that the cold storage door cannot be opened from the inside, and avoids the low temperature being transmitted to the outside through the metal handle, causing the door handle to freeze and become unable to be operated. However, when someone is mistakenly locked in the cold storage, the user who is mistakenly locked cannot escape in time and causes frostbite.
