[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 and Figure 2, shown in the figure is the connection structure between the battery cover and the battery cylinder of a multi - section battery box, including a battery cover 1 and a battery cylinder 2. There is a chamber for storing batteries inside the battery cylinder 2. It should be noted that the battery cover 1 is snap - connected to the battery cylinder 2. A clamping position 3 is provided on the inner wall of the open end of the battery cylinder 2, and a buckle 4 that is snap - connected to the clamping position 3 on the inner wall of the battery cylinder 2 is provided on the corresponding battery cover 1. In this embodiment, the middle part between the two buckles 4 on the battery cover 1 is a hollow structure 5 for the battery cover 1 to be compressed and contracted inward. When the two sides of the battery cover 1 are squeezed, the buckles 4 contract inward to cause the disengagement. This structure can open the battery cover 1 by squeezing the two sides of the battery cover 1, which is convenient and fast to open the cover.

[0022] Embodiment Two

[0023] Please refer to Figure 3 and Figure 4 , the difference between this embodiment and Embodiment One is that: a movable part 6 is provided on the battery cylinder 2 corresponding to the position of the buckle 4 of the battery cover 1. When the battery cover 1 and the battery cylinder 2 are in snap - fit with the buckle 4, the position of the movable part 6 corresponds to the position of the buckle 4 of the battery cover 1. By pressing the movable part 6, the buckle 4 of the battery cover 1 is driven to disengage, so as to facilitate the disassembly of the battery cover 1. In this embodiment, the movable part is a part of the battery cylinder, which is formed by cutting a "U - shaped track groove" or a "凵" - shaped track groove on the wall of the battery cylinder. Since the battery cylinder is made of plastic, the movable part has a certain elasticity and can automatically rebound after pushing open the buckle. It should be noted that in this embodiment, the movable part is provided directly below the clamping position, and when the movable part is squeezed inward, it can push open the buckle.

[0024] Embodiment Three

[0025] Please refer to Figure 5 , the difference between this embodiment and Embodiment One is that: a buckle 4 is provided on the outer wall of the open end of the battery cylinder 2, and a clamping part 7 extending downward is provided on the corresponding battery cover 1. A clamping position 3 that is snap - connected to the buckle 4 is provided on the clamping part 7.

[0026] Embodiment Four

[0027] Please refer to Figure 6 , the difference between this embodiment and Embodiment Three is that: in this embodiment, cut grooves 8 for enabling the position of the buckle 4 to move are provided on both sides of the buckle 4, and a shrinking space 9 for the position where the buckle 4 of the battery cylinder 2 is installed is provided on the corresponding battery cover 1. When disassembling the battery cover 1, only need to squeeze the battery cylinder 2 at the position between the cut grooves 8 inward, then the battery cover 1 and the battery cylinder 2 can be disengaged, and the disassembly is convenient and fast.

[0028] Embodiment Five

[0029] Please refer to Figure 7The difference between this embodiment and the fourth embodiment is that the periphery of the buckle 4 of this embodiment is concave, and a through groove 10 communicating with the concave periphery of the buckle 4 is provided on the outer wall of the battery tube 2. The provision of the through groove 10 not only makes it easier to process the mold of the buckle 4, but also makes it easier to pry open the clamping portion 7 on the battery cover 1, thereby facilitating the removal of the battery cover 1.
