Description

Technical Field

[0001] This utility model belongs to the field of lithium battery related technology, and in particular relates to a lithium battery protection box that is easy to assemble. Background Technology

[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Lithium batteries are easily damaged by external factors, so they are usually protected by a casing.

[0003] Conventional lithium battery cases are mostly just a box with a cover for fixing, without any special structural features. In actual use, the only requirement is to ensure that the lithium battery does not shift. The overall structure is not convenient to combine and is not convenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a conveniently assembled lithium battery protection housing, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a conveniently assembled lithium battery protection box, comprising a box body and mating components. The top of the box body is open, and slide rails are provided on both sides of the top of the box body. A connecting block is fixedly connected to the bottom surface of the box body, and the connecting block is inserted and adapted to the slide rail. A mating block is fixedly connected to one side of the box body, and a mating groove is opened on the other side of the box body, and the mating groove is inserted and adapted to the mating block. The mating components include a fixing seat and a positioning block. The fixing seat is disposed on one side of the surface of the box body and is fixedly connected to the box body. The positioning block is disposed on the other side of the surface of the box body and is fixedly connected to the box body.

[0007] The fixed base is internally hinged with a linkage rod, which is U-shaped. One end of the linkage rod is fixedly connected to a positioning protrusion. The surface of the positioning protrusion is provided with an arc-shaped groove, and the positioning protrusion and the arc-shaped groove are engaged. The shape of the arc-shaped groove is adapted to the trajectory of the linkage rod driving the positioning protrusion to move.

[0008] Both the mating block and the mating groove are in the shape of an isosceles trapezoid.

[0009] The fixing seat is located on the side near the mating groove, and the positioning block is located on the side near the mating block.

[0010] One end of the slide rail is fixedly connected to a mounting plate, and mounting screws are provided inside the mounting plate.

[0011] Both sides of one end of the connecting block are provided with mating screw holes, which are adapted to the threads of the mounting screws.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, by setting up a box body and matching components, allows for the vertical stacking of box bodies when assembling two or more sets of box bodies. The connecting block on the bottom surface of one box body is inserted into the slide rail at the top of another box body and tightly fitted to the mounting plate, then secured with mounting screws. This process is repeated to allow the box bodies to be stacked vertically, resulting in a simple structure and reduced space requirements. Alternatively, a matching block on one side of one box body is inserted into a matching groove on the side of another box body, and then a swing linkage rod is used to slide the positioning protrusion into the arc-shaped groove of the positioning block, completing the snap-fit ​​engagement. This process is repeated to allow the box bodies to be horizontally assembled, resulting in a simple structure and improved ease of use.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figures 1-5 As shown, this utility model is a conveniently assembled lithium battery protection box, including a box body 1 and a mating component 2. The top of the box body 1 is open, and slide rails 101 are provided on both sides of the top of the box body 1. A connecting block 102 is fixedly connected to the bottom surface of the box body 1. The connecting block 102 is inserted and adapted to the slide rail 101. A mating block 103 is fixedly connected to one side of the box body 1, and a mating groove 104 is opened on the other side of the box body 1. The mating groove 104 is inserted and adapted to the mating block 103. The mating component 2 includes a fixing seat 201 and a positioning block 204. The fixing seat 201 is disposed on one side of the surface of the box body 1 and is fixedly connected to the box body 1. The positioning block 204 is disposed on the other side of the surface of the box body 1 and is fixedly connected to the box body 1.

[0027] The fixed base 201 has a hinged linkage 202 inside. The linkage 202 is U-shaped. One end of the linkage 202 is fixedly connected to a positioning protrusion 203. The surface of the positioning block 204 is provided with an arc-shaped groove 205. The positioning protrusion 203 and the arc-shaped groove 205 are engaged. The shape of the arc-shaped groove 205 is adapted to the trajectory of the linkage 202 driving the positioning protrusion 203 to move.

[0028] Both the mating block 103 and the mating groove 104 are in the shape of an isosceles trapezoid.

[0029] The fixed seat 201 is located on the side close to the mating groove 104, and the positioning block 204 is located on the side close to the mating block 103.

[0030] One end of the slide rail 101 is fixedly connected to a mounting plate 105, and the mounting plate 105 is fitted with mounting screws 106.

[0031] Both sides of one end of the connecting block 102 are provided with mating screw holes 107, which are threaded to fit the mounting screws 106.

[0032] It should be noted that the top of the box body 1 is covered with a cover (not shown in the figure).

The placement of the box body 1, the cover and the lithium battery inside the box body 1 are all existing technologies and can be effectively known to those skilled in the art. The details will not be elaborated further. In practical use, when combining two or more sets of box bodies 1, the connecting block 102 on the bottom surface of box body 1 is inserted into the slide rail 101 at the top of another set of box bodies 1 and is tightly attached to the mounting plate 105. The connecting block 102 acts as a box cover, and is then fixed with mounting screws 106. This process is repeated to allow the box bodies 1 to be vertically stacked and combined. The structure is simple and reduces the space occupied. The top box body 1 is fixed to it by the box cover. The mating block 103 on one side of box body 1 is inserted into the mating groove 104 on one side of another set of box bodies 1. Then, the linkage rod 202 is swung to make the positioning protrusion 203 slide into the arc groove 205 of the positioning block 204 to complete the snap-fit ​​engagement. This process is repeated to allow the box bodies 1 to be horizontally combined. The structure is simple and improves the convenience of use to a certain extent.
