Description

Technical Field

[0001] This utility model relates to the field of isolation device technology, and in particular to an isolation frame. Background Technology

[0002] Lithium batteries stored in warehouses may experience thermal runaway if the ambient temperature is too high, they are subjected to pressure, or they are short-circuited. This can damage the internal separator of the lithium battery, causing it to catch fire. The resulting fire can produce flames or flying debris, which can quickly ignite surrounding goods. Therefore, lithium batteries need to be stored separately from surrounding goods to prevent the fire caused by thermal runaway from spreading. Utility Model Content

[0003] The primary objective of this invention is to propose an isolation frame for isolating lithium batteries, which can effectively isolate and protect lithium batteries and prevent the spread of fire caused by thermal runaway of lithium batteries.

[0004] To achieve the above objectives, this utility model provides an isolation frame, including uprights, a first connecting mechanism, and a fireproof blanket. The uprights are multiple and spaced apart. Adjacent uprights are connected by the first connecting mechanism, and all uprights and the first connecting mechanism together form a frame. The inner side of the frame forms a placement space, and the fireproof blanket covers the outer side of the frame and shields the placement space. The first connecting mechanism is extendable to adjust the distance between adjacent uprights.

[0005] In a specific embodiment of this utility model, the first connecting mechanism includes a scissor-type telescopic linkage assembly. In the telescopic direction of the first connecting mechanism, one end of the scissor-type telescopic linkage assembly is connected to one of the corresponding columns, and the other end is connected to another corresponding column.

[0007] Along the arrangement direction of the plurality of columns in the frame, the first column is a first column body, and the last column body is a second column body. The first column body and the second column body are detachably connected by the second connecting mechanism.

[0008] In a specific embodiment of this utility model, the second connecting mechanism includes a first connecting block, a second connecting block, a third connecting block, and a snap-fit ​​post. The first connecting block is fixedly disposed on the first post, the second connecting block is fixedly disposed on the second post, the third connecting block is rotatably connected to the second connecting block, and the snap-fit ​​post is fixedly disposed on the first connecting block.

[0009] The bottom of the third connecting block is provided with a slot, which is engaged with the snap-fit ​​post.

[0010] In a specific embodiment of this utility model, the fireproof blanket includes a cover part and a shielding part;

[0011] The cover portion is fitted onto the frame, and the cover portion has an opening facing the side where the second column is located;

[0012] In the arrangement direction of the plurality of columns in the frame, one end of the shielding part is connected to the cover part and the other end is connected to the second column, and the shielding part covers the opening.

[0013] In a specific embodiment of this utility model, the isolation frame further includes hooks, and the hooks are connected to the frame, wherein each of the uprights is provided with a corresponding hook;

[0014] The fireproof blanket is provided with multiple hanging holes, and each hanging hole is attached to a hook.

[0019] The present invention provides an isolation frame, which, compared with the prior art, has the following advantages:

[0020] The isolation frame of this utility model consists of a column and a first connecting mechanism connected to form a frame. The inner side of the frame forms a placement space, while a fire blanket is placed on the outer side of the frame and covers the placement space. This isolation frame is used to isolate lithium batteries. In practical applications, the lithium batteries are placed in the placement space. At this time, the lithium batteries are located inside the fire blanket. Based on this, the isolation and protection of lithium batteries can be effectively achieved, and the spread of fire caused by thermal runaway and fire of lithium batteries can be avoided.

[0021] In addition, since the first connecting mechanism is telescopic, when isolating the lithium battery, the first connecting mechanism is in the extended state, at which time the frame has a relatively large placement space to place the lithium battery. When the frame does not need to isolate the lithium battery and is in an idle state, the first connecting mechanism can be retracted from the extended state to the retracted state. At this time, the frame occupies less space and is easy to store. Attached Figure Description

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] like Figures 1 to 5 As shown, an isolation frame according to an embodiment of the present invention includes columns 1, a first connecting mechanism 2, and a fireproof blanket 3. There are multiple columns 1, which are spaced apart. Adjacent columns 1 are connected by the first connecting mechanism 2, and all columns 1 and all first connecting mechanisms 2 together form a frame 10. The inner side of the frame 10 forms a placement space 100. The fireproof blanket 3 covers the outer side of the frame 10 and shields the placement space 100. The first connecting mechanism 2 can extend and retract to adjust the distance between adjacent columns 1.

[0030] Specifically, in this embodiment, the isolation frame consists of a column 1 and a first connecting mechanism 2 connected to form a frame 10. A placement space 100 is formed inside the frame 10, while a fire blanket 3 covers the outside of the frame 10 and shields the placement space 100. This isolation frame is used to isolate lithium batteries. In practical applications, the lithium batteries are placed within the placement space 100, and are located within the fire blanket 3. This effectively isolates and protects the lithium batteries, preventing the spread of fire caused by thermal runaway. Furthermore, since the first connecting mechanism 2 is extendable, it can be extended when isolating lithium batteries, providing a larger placement space 100 for the lithium batteries. When the frame 10 is not needed for lithium battery isolation and is idle, the first connecting mechanism 2 can be retracted from the extended state to the retracted state. At this time, the structure of the frame 10 is as follows: Figure 5 As shown, frame 10 occupies a relatively small space, making it easy to store.

[0031] In this embodiment, as Figure 3 As shown, the first connecting mechanism 2 includes a scissor-type telescopic linkage assembly. In the telescopic direction of the first connecting mechanism 2, one end of the scissor-type telescopic linkage assembly is connected to a corresponding column 1, and the other end is connected to another corresponding column 1. The scissor-type telescopic linkage assembly is usually composed of one or more pairs of cross-connected links. It achieves telescopic movement by changing the angle between the links. The scissor-type telescopic linkage assembly is existing technology, and this application will not elaborate on it further. This application uses a scissor-type telescopic linkage assembly to adjust the distance between two adjacent columns 1. Its structure is simple and its operation is convenient.

[0032] In this embodiment, as Figure 2 As shown, the orthographic projection of the frame 10 on the horizontal plane is rectangular. This type of isolation frame is structurally stable and reliable, and the first connecting mechanism 2 is easy to extend and retract.

[0033] Furthermore, such as Figure 3 As shown, the isolation frame also includes a second connecting mechanism 4; along the arrangement direction of the multiple columns 1 in the frame 10, the first column 1 is the first column 11, and the last column 1 is the second column 12. The first column 11 and the second column 12 are detachably connected through the second connecting mechanism 4, that is, the multiple columns 1 are connected end to end, and the multiple columns 1 and the first connecting mechanism 2 are connected to form a closed frame 10, and the frame 10 has a stable and reliable structure; specifically, after the first column 11 and the second column 12 are disassembled and separated, the first connecting mechanism 2 between the second column 12 and the column 1 away from the first column 11 is driven to retract, which can make the frame 10 form an opening. At this time, it is convenient to put the lithium battery into the placement space 100 or take it out from the placement space 100. The structure is simple and the operation is convenient.

[0034] In this embodiment, as Figure 4 As shown, the second connecting mechanism 4 includes a first connecting block 41, a second connecting block 42, a third connecting block 43, and a locking post 44. The first connecting block 41 is fixedly mounted on the first column 11, the second connecting block 42 is fixedly mounted on the second column 12, the third connecting block 43 is rotatably connected to the second connecting block 42, and the locking post 44 is fixedly mounted on the first connecting block 41. The bottom of the third connecting block 43 has a locking groove 4301, which is engaged with the locking post 44. Therefore, by rotating the third connecting block 43 upwards, the locking groove 4301 disengages from the locking post 44, thus separating the first column 11 from the second main body. This operation is simple and convenient. Similarly, when it is necessary to connect the first column 11 and the second column 12, simply pull the second column 12 to a preset position and then rotate the third connecting block 43 to engage the locking groove 4301 with the locking post 44. This operation is also simple and convenient.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the fire blanket 3 includes a cover part 31 and a shielding part 32. The cover part 31 is placed on the frame 10 and has an opening 3101 facing the side where the second column 12 is located. In the arrangement direction of the multiple columns 1 in the frame 10, one end of the shielding part 32 is connected to the cover part 31 and the other end is connected to the second column 12. The shielding part 32 shields the opening 3101. Based on this, since the fire blanket 3 is a fabric woven from materials such as glass fiber through special treatment, it has the characteristics of being soft, elastic, and having a certain tensile strength. Therefore, when the second column 12 is pulled to retract the corresponding first connecting mechanism 2, the shielding part 32 can retract with the second column 12, thereby opening the opening 3101, so that the lithium battery can be put in or taken out. The structure is simple and the operation is convenient.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the isolation frame also includes hooks 5, and hooks 5 are connected to the frame 10. Each column 1 is provided with a corresponding hook 5. The fire blanket 3 is provided with multiple hanging holes 301, and one hanging hole 301 is hung on one hook 5. Thus, the fire blanket 3 can be stably connected to the frame 10.

[0037] Preferably, each end of the column 1 is provided with a hook 5, which can further improve the stability of the connection between the fire blanket 3 and the frame 10.

[0038] Furthermore, such as Figure 2As shown, the isolation frame also includes a connecting ring 6. Each hanging hole 301 is connected to a connecting ring 6. The connecting ring 6 is coaxially arranged with the hanging hole 301. The connecting ring 6 is connected to the hook 5. Specifically, the material of the connecting ring 6 can be metal, plastic, aluminum alloy, etc. The connecting ring 6 is not easily deformed. The fire blanket 3 is hung on the hook 5 through the connecting ring 6, which is convenient to operate.

[0039] Furthermore, such as Figure 3 and Figure 5 As shown, the isolation frame also includes casters 7. Each column 1 is connected to a caster 7 at its bottom. The casters 7 are braked, thus the isolation frame has the advantages of being easy to move and stable to place.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
