[0002] Cold storage is a man-made low-temperature environment device, mainly used for storing temperature-sensitive items such as food, medicine, and chemical raw materials. It extends the shelf life of the items or maintains their activity by maintaining constant temperature and humidity conditions.

[0003] Traditional cold storage doors are typically secured to the cold storage unit with numerous bolts. Users need to tighten a large number of bolts during installation, making the process cumbersome and reducing efficiency. Therefore, there is an urgent need for an easier-to-install insulated cold storage door. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a composite vacuum insulation panel for heat-insulating cold storage doors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A composite vacuum insulation panel-based insulated cold storage door includes a cold storage body and an outer door frame. An inner door frame is fixedly installed inside the cold storage body, and the outer door frame is assembled onto the inner door frame via multiple mounting components. The insulated cold storage door body is installed on the outer door frame. The inner door frame has mounting cavities corresponding to the mounting components. Movable components are movably installed on both sides of the mounting components via push plates, and limit cavities are provided on both sides of the mounting cavities corresponding to the movable components.

[0007] Furthermore, in a preferred configuration, each of the mounting components has a through cavity, with movable components movably disposed on both sides of the through cavity, and a push plate movably disposed between the movable components on both sides.

[0008] In addition, a preferred structure is that a partition is fixedly provided in the middle of each mounting component, and springs are installed on both sides of the partition facing the movable component, and the other end of each spring is connected to the movable component.

[0009] In addition, a preferred structure is that one end of each of the movable parts is fixedly provided with a sub-arc surface, and the end of the push plate is adapted to have a mother arc surface corresponding to the sub-arc surface.

[0010] Furthermore, in a preferred configuration, the mounting component has side cavities on both sides of the push plate, and elastic clips are installed in each side cavity.

[0011] In addition, a preferred structure is that the elastic clips on both sides of the push plate are adapted to have clip cavities, and when the mother arc surface of the push plate contacts the partition, the elastic clips are adapted to be clipped into the clip cavities.

[0012] In addition, a preferred structure is that the interior of the insulated cold storage door body is equipped with a vacuum insulation panel.

Detailed Implementation

[0025] 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.

[0026] Reference Figure 1-10 A composite vacuum insulation panel-based insulated cold storage door includes a cold storage body 1 and an outer door frame 2. An inner door frame 3 is fixedly installed inside the cold storage body 1. The outer door frame 2 is assembled onto the inner door frame 3 via multiple mounting parts 4, and the insulated cold storage door body 21 is installed on the outer door frame 2. The inner door frame 3 has mounting cavities 31 corresponding to the mounting parts 4. Movable parts 5 are movably installed on both sides of the mounting parts 4 via push plates 6, and limiting cavities 32 are provided on both sides of the mounting cavities 31 corresponding to the movable parts 5.

[0027] The mounting component 4 has a through cavity inside, and movable components 5 are movably arranged on both sides of the through cavity. A push plate 6 is movably arranged between the movable components 5 on both sides.

[0028] Each mounting component 4 has a partition 41 fixedly installed in the middle. Springs 42 are installed on both sides of the partition 41 facing the movable component 5, and the other end of each spring 42 is connected to the movable component 5. The springs 42 allow the movable components 5 on both sides to be pushed inwards, so that when the movable components 5 are not blocked by the push plate 6, they can automatically return to their original position within the mounting component 4 due to the elastic force of the springs 42.

[0029] Each of the movable parts 5 has a sub-arc surface 51 fixedly provided at one end, and the end of the push plate 6 is provided with a mother arc surface 61 corresponding to the sub-arc surface 51. Through the adaptation between the sub-arc surface 51 and the mother arc surface 61, when the push plate 6 pushes between the movable parts 5 on both sides, it can push the movable parts 5 on both sides to the side.

[0030] The mounting component 4 has side cavities 43 on both sides of the push plate 6, and each side cavity 43 contains an elastic locking element 431. Corresponding to the elastic locking elements 431, each side of the push plate 6 has a locking cavity 62. When the mother arc surface 61 of the push plate 6 contacts the partition plate 41, the elastic locking element 431 and the locking cavity 62 are engaged. Through the engagement of the elastic locking element 431 and the locking cavity 62, the push plate 6 can be fixed, allowing it to stably push the movable parts 5 on both sides outwards.

[0031] In this embodiment, the inner door frame 3 is fixedly installed on the cold storage body 1. The user only needs to assemble the outer door frame 2 onto the inner door frame 3 using the mounting bracket 4. It is worth noting that the insulated cold storage door body 21 is mounted on the outer door frame 2, and a composite vacuum insulation panel is installed inside it. Furthermore, the insulation material of the cold storage body 1 is placed in the gap between the inner door frame 3 and the outer door frame 2 to improve insulation performance. This is prior art and not related to the ease of assembly technical problem addressed in this technical solution; therefore, it will not be elaborated upon further.

[0032] Furthermore, when the user needs to install the outer door frame 2, they only need to fit and insert the mounting parts 4 on the outer door frame 2 into the mounting cavity 31 inside the inner door frame 3. At this time, the movable parts 5 on both sides of the mounting parts 4 are aligned with the limiting cavity 32. Then, the user only needs to enter the interior of the cold storage body 1 and push the push plates 6 on the mounting parts 4 inward.

[0033] When the push plate 6 moves into the mounting component 4, the mating arrangement between the mother arc surface 61 and the daughter arc surface 51 pushes the movable parts 5 on both sides outward. This compresses the movable parts 5 within the mounting component 4 into the limiting cavity 32, and all springs 42 are stretched. When the end of the push plate 6 contacts the partition plate 41, the locking cavities 62 on both sides of the push plate 6 are aligned with the elastic locking elements 431. At this time, the elastic locking elements 431 automatically lock into the locking cavities 62 through their own elastic force, thus fixing the push plate 6. When the user moves all the movable parts 5 into the limiting cavity 32 using the push plate 6, the external door frame 2 is fixedly installed.

[0034] Furthermore, when the user needs to disassemble the outer door frame 2, they only need to push the elastic clips 431 on both sides outward to release the locking between the elastic clips 431 and the locking cavity 62, and then the push plate 6 can be pulled out. This releases the pressure of the push plate 6 on the movable part 5, at which point the movable part 5 can automatically return to the mounting part 4 by the elastic force of the spring 42, thereby releasing the locking between the movable part 5 and the limiting cavity 32. When the user pulls out all the push plates 6, the outer door frame 2 can be disassembled.

[0035] Furthermore, guide members are adapted to be provided within the mounting component 4 for both the movable component 5 and the push plate 6, and guide grooves are adapted to be provided on the guide members for both the movable component 5 and the push plate 6. The adapted arrangement between the guide members and the guide grooves not only improves the stability of the movable component 5 and the push plate 6 during movement, but also prevents the movable component 5 and the push plate 6 from falling out of the mounting component 4.

[0036] Furthermore, the insulated cold storage door body 21 is based on a polyurethane foam door panel structure. A vacuum insulation panel is pre-installed within the original polyurethane foam space, and then the vacuum insulation panel is fixed inside the insulated cold storage door body 21 using a polyurethane foaming process. This achieves energy-saving results. Because the thermal conductivity of the vacuum insulation panel is extremely low (typically below 0.005 W / m·K), significantly better than traditional polyurethane foam materials (0.02-0.03 W / m·K), its application in the insulated cold storage door body 21 can achieve better insulation performance, thereby reducing energy consumption.

[0037] Furthermore, the thickness of vacuum insulation panels is typically 20-40mm, which is much lower than that of traditional insulation materials (typically 80-150mm), thus reducing the thickness of the insulated cold storage door body 21.

[0038] In this utility model, the push plate 6 presses the movable part 5, so that the movable part 5 can be firmly locked in the limiting cavity 32, and the elastic locking part 431 locks the push plate 6, thus achieving a stable installation of the outer door frame 2. This method of installing the insulated cold storage door body 21 is simple and convenient, making it easy for users to install the insulated cold storage door body 21.

[0039] 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.
