[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] The utility model provides a power supply housing through improvement. The technical solution of the utility model is:

[0024] like Figure 1 - Figure 7 As shown, a power supply housing includes a lower cover plate 1, the lower surface of the lower cover plate 1 is fixedly connected with two first mounting blocks 2 and two second mounting blocks 3, the two first mounting blocks 2 and the second mounting blocks 3 are respectively located at the two ends of the bottom of the lower cover plate 1, a plurality of first grooves 4 are provided on the left side wall of the lower cover plate 1, and two second grooves 5 are provided on the right side wall of the lower cover plate 1, an upper cover plate 7 is arranged above the lower cover plate 1, rectangular holes 8 are provided on both sides of the upper cover plate 7, a plurality of third grooves 9 are provided on the left side wall of the upper cover plate 7, two fourth grooves 10 are provided on the right side wall of the upper cover plate 7, a double-head clamping block 11 is fixedly connected to the left side wall of the upper cover plate 7, a battery compartment 12 is provided on the upper surface of the upper cover plate 7, and a battery cover plate 15 is arranged above the battery compartment 12.

[0025] Furthermore, the plurality of first grooves 4 correspond to the plurality of third grooves 9 one by one, and the first grooves 4 and the third grooves 9 are combined into a rectangle, and the wires can pass through the combined rectangular through grooves to connect the inside and outside of the power supply.

[0026] Furthermore, the inner wall of the lower cover plate 1 is fixedly connected with a plurality of groups of symmetrically arranged protrusions 6, which are snap-fitted with the rectangular holes 8. The size of the protrusions 6 matches the rectangular holes 8, and the lower cover plate 1 and the upper cover plate 7 are snap-fitted together by snapping the protrusions 6 with the rectangular holes 8.

[0027] Furthermore, the two second grooves 5 correspond to the two fourth grooves 10 one by one, and the second grooves 5 and the fourth grooves 10 are combined into two mounting holes, and the wires can pass through the combined rectangular through grooves to connect the inside and outside of the power supply.

[0028] Furthermore, the inner wall of the battery compartment 12 is provided with two symmetrically arranged snap-in openings 13 , and the upper surface of the upper cover plate 7 is provided with a mounting groove 14 . When the battery cover plate 15 is placed in the battery compartment 12 , the mounting groove 14 limits the snap-in openings 13 .

[0029] Furthermore, a V-shaped block 16 is fixedly connected to the left side wall of the battery cover 15, and a block 17 is fixedly connected to the right side wall of the battery cover 15.
