Technical Field

[0001] The utility model relates to the technical field of lithium battery bundling steel belt structures, in particular to a combined battery steel belt. Background Art

[0002] The structure of the existing lithium battery steel strip is welded into an integral rectangular frame structure. During the production and processing of the steel strip, the steel strip needs to be guided out from the reel, cut into a fixed length, and then bent into a U shape. Subsequently, the two ends of the U-shaped steel strip are bent, welded or threaded to form a rectangular frame. Such battery steel is formed in a complex manner through welding and threading, and during sales and transportation, the battery steel strip cannot be disassembled and occupies a large space. Therefore, there is an urgent need for a combined battery steel strip that is not only simple and convenient to form, but also can reduce the space occupied by the battery steel strip.

[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0029] Please refer to Figures 1 to 8 A combined battery steel strip comprises two straight segments 1 and two U-shaped segments 2, both ends of the straight segment 1 are provided with a first connecting portion 11, the first connecting portion 11 is provided with a limiting groove 111, and a limiting mechanism 3 is provided in the limiting groove 111;

[0030] The limiting mechanism 3 includes a spring 35, a limiting column 31, a limiting block 32, a threaded column 33, and a knob 34. The first connecting portion is provided with a threaded hole 112 matching the threaded column 33. The spring 35 is connected to the inner wall of the limiting groove 111. The limiting column 31 is coaxially sleeved in the spring. The limiting block 32 is connected to one end of the spring 35 away from the limiting column 31. The limiting block 32 is provided with a first slope 321. One end of the limiting column 31 is connected to one end of the threaded column 33 through a bearing seat. The knob 34 is connected to the other end of the threaded column.

[0031] Both ends of the U-shaped section 2 are provided with a second connecting portion 21, the second connecting portion 21 is provided with a second slope 211 matching the first slope 321, the second connecting portion 21 is provided with a slot 212 matching the limit block 32, and the slot 212 is located in the X direction of the second slope 211;

[0032] In the assembled state, the threaded column 33 is threadedly connected with the threaded hole 112, and the limit block 32 is inserted into the slot 212 to connect the U-shaped segment 2 and the straight segment 1;

[0033] In the disengaged state, the threaded column 33 is disengaged from the threaded hole 112 , the spring 35 is located in the threaded hole 112 , and the limiting block 32 is disengaged from the slot 212 .

[0034] In the above embodiment, one end of the U-shaped segment 2 is aligned with one end of one of the straight segments 1, and the two first segments of the U-shaped segment 2 are aligned with one end of another straight line, and one end of the two straight line segments 1 is located on the same side. The second slope 211 first contacts the first slope 321 to compress the spring 35, allowing the second connecting portion 21 to enter the limiting groove 111. When the limiting column 31 is inserted into the slot 212, the spring 35 rebounds, so that the limiting block 32 is clamped in the slot 212, thereby fixing the U-shaped segment 2 and the straight line segment 1 to form a battery steel strip, which is more convenient and efficient than welding and threaded connection. When transportation and sales are required, the knob 34 is unscrewed to unscrew the entire spring 35 outward, so that the spring 35 is located in the threaded hole 112, and then the limiting block 32 is disengaged from the slot 212, thereby disengaging the U-shaped segment 2 from the straight line segment 1, and the battery steel strip becomes a straight line segment 1 and a U-shaped segment 2, reducing the space occupied, and performing separate packaging, which is convenient for sales.

[0035] As an optional implementation, there are two limiting mechanisms 3 , and the two limiting mechanisms 3 are arranged opposite to each other on the inner wall of the limiting groove 111 .

[0036] In the above embodiments, the U-shaped segment 2 and the straight segment 1 are limited by two limiting mechanisms 3 to ensure the stability of the connection.

[0037] As an optional implementation, the second connecting portion 21 is provided with two second slopes 211 symmetrical in the Z direction, the distance between the two second slopes 211 is L4, the distance between the two limit blocks 32 of the two limit mechanisms 3 is Q5, and Q5 is greater than L4.

[0038] In the above embodiment, when the distance Q5 is greater than L4, it can facilitate the insertion of the two ends of the U-shaped segment 2, and the second slope 211 can smoothly squeeze the first slope 321, so that the spring 35 contracts and the limit block 32 is inserted into the slot 212, so that the U-shaped segment 2 and the straight segment 1 are stably connected.

[0039] As an optional implementation, the slot 212 is in the shape of a rectangular slot.

[0040] In the above embodiment, the first slope 321 can be better embedded in the slot 212 to ensure that it will not fall out of the slot 212, thereby ensuring the stability of the connection.

[0041] As an optional implementation, the knob 34 is provided with anti-slip grooves 341 .

[0042] In the above embodiment, the first slope 321 can be better disengaged from the slot 212 by using the knob 34 .

[0043] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
