[0018] A letting block 21 is fixedly connected to one side of the connecting rod 14, and a pushing block 22 is fixedly connected to the inner wall of the limit groove 5. The letting block 21 is of a trapezoidal structure; by providing the letting block 21 and the pushing block 22, when the explosion-proof glass 3 is closed, the pushing block 22 will push the letting block 21, separating the first magnet 19 and the second magnet 20, so that the connecting rod 14 is separated from the clamping post 18, and then the second spring 11 will move the positioning block 10 behind the limit block 7, thereby limiting the explosion-proof glass 3.

[0019] A grasping groove 23 is formed in the cabinet door 2, and a rubber sleeve 24 is fixedly installed on one side of the cabinet door 2. The push plate 15 is located inside the rubber sleeve 24; the formation of the grasping groove 23 facilitates pulling the cabinet door 2, and the rubber sleeve 24 can protect the push plate 15 and the connecting rod 14, and also prevent accidental contact with the user.

[0020] Working principle: If you need to open the refrigerator to take items, you can press the push plate 15 to push the connecting rod 14 so that the limit hole 17 at one end of it sleeved on the clamping post 18, and then make the positioning block 10 and the limit block 7 misaligned, and then you can pull the explosion-proof glass 3 and the cabinet door 2. If you do not press the push plate 15 and pull the cabinet door 2, you cannot pull open the explosion-proof glass 3 and cannot take the items inside the refrigerator body 1, which can prevent children from taking the items inside the refrigerator body 1.
