[0008] In addition, a preferred structure is that the cold storage door body has sliding grooves on both sides of the observation window, and the protective plate is fitted with sliders corresponding to the sliding grooves.
[0009] In addition, a preferred structure is that each of the card blocks is fixedly provided with multiple guide posts, and the corresponding guide posts on the fixing base are adapted to have guide cavities.
[0010] In addition, a preferred structure is that all the guide posts are adapted to pass through the guide cavity, and the ends of the guide posts are all fixedly provided with anti-detachment components.
[0011] In addition, a preferred structure is that each of the card blocks is fixedly provided with a pull rod, the pull rod passes through the fixed base, and the end of each pull rod is fixedly provided with a handle.
[0012] In addition, a preferred structure is that springs are installed on the side of the fixed base facing the locking block, the other end of each spring is connected to the locking block, and the springs are located on the outside of the pull rod.
[0013] The beneficial effects of this utility model are as follows: a movable protective plate is provided on the outside of the cold storage door body. By moving the protective plate to the outside of the observation window, the observation window can be protected to prevent items from directly hitting the observation window during handling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-6A cold storage door with protective functions includes a door body 1, an observation window 11 on the door body 1, a protective plate 2 vertically movable on the outside of the observation window 11, and latching blocks 4 movable on both sides of the protective plate 2 on the door body 1. Slots 21 are provided on both sides of the protective plate 2 corresponding to the latching blocks 4, and fixing seats 3 are fixedly installed on the outside of the latching blocks 4 on the door body 1, with the latching blocks 4 connected to the fixing seats 3 by springs 43.
[0023] The cold storage door body 1 is installed on the cold storage via an opening and closing pivot, which is existing technology and will not be described in detail.
[0024] The cold storage door body 1 has sliding grooves 12 on both sides of the observation window 11, and the protective plate 2 has corresponding sliders 22 fitted onto the sliding grooves 12. The fit between the sliding grooves 12 and the sliders 22 can improve the stability of the protective plate 2 during movement.
[0025] Each of the card blocks 4 has multiple guide posts 41 fixedly installed, and each guide post 41 on the fixing base 3 is adapted to have a guide cavity 31. Each guide post 41 is adapted to pass through the guide cavity 31, and each end of the guide post 41 is fixedly provided with an anti-detachment component 411. The guide posts 41 are used to guide the card blocks 4, and the anti-detachment components 411 are used to prevent the card blocks 4 from falling off the fixing base 3.
[0026] Each of the locking blocks 4 is fixedly equipped with a pull rod 42, which passes through the fixed base 3, and each pull rod 42 has a handle 421 fixedly installed at its end. The pull rod 42 and handle 421 make it easy for the user to move the locking block 4.
[0027] Among them, springs 43 are installed on the side of the fixed base 3 facing the locking block 4, and the other end of the springs 43 are connected to the locking block 4. The springs 43 are located on the outside of the pull rod 42.
[0028] In this embodiment, by moving the protective plate 2 to the observation window 11, the observation window 11 can be protected to prevent items from directly impacting the observation window 11 during handling.
[0029] Furthermore, when the user needs to protect the observation window 11, they simply pull the handles 421 on both sides outwards. This will cause the pull rod 42 and the locking block 4 to move outwards. At this time, the spring 43 is compressed, and the locking block 4 disengages from the slot 21, thus releasing the mutual locking between the locking block 4 and the slot 21. The protective plate 2 can then automatically fall to the observation window 11 under its own weight, thereby protecting the observation window 11.
[0030] Furthermore, when the user needs to observe the interior of the cold storage through the observation window 11, they simply need to lift the protective plate 2 to its highest position. Since the locking block 4 is wedge-shaped with its inclined surface at the top, when the locking blocks 4 on both sides contact the protective plate 2, the locking blocks 4 can automatically move outwards, and the spring 43 is compressed. When the protective plate 2 moves to its highest point, the locking groove 21 on the protective plate 2 aligns with the locking block 4. At this time, the spring 43 can push the locking block 4 into the locking groove 21 through its own elastic force. Thus, the protective plate 2 is fixed in place by the mutual locking between the locking block 4 and the locking groove 21, preventing it from falling automatically. The user can then observe the interior of the cold storage through the observation window 11.
[0031] In this utility model, a movable protective plate 2 is provided on the outside of the cold storage door body 1. By moving the protective plate 2 to the outside of the observation window 11, the observation window 11 can be protected to prevent items from directly hitting the observation window 11 during handling.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
