The edge of the other sealing plate is embedded into the lap joint groove, and the lap joint edge covers the gap between the main plate part and the adjacent sealing plate. According to the battery box provided by the embodiment of the invention, the concave lap joint edges are arranged on at least part of the sealing plates, so that a limiting effect is achieved, the adjacent sealing plates can be conveniently and quickly assembled in place, and the lap joint edges shield a gap between the two adjacent sealing plates, so that the battery box has the effects of protecting an internal battery pack and being attractive.

The utility model discloses a convenient-to-install quick connecting and fixing structure for water and electricity heating pipelines, which comprises a first pipeline and a second pipeline, a connecting seat is arranged between the first pipeline and the second pipeline, and the first pipeline and the second pipeline are connected with each other through a connecting pipe; the splicing assembly is arranged between the two first pipelines and the two second pipelines, and the splicing assembly is used for locking the two first pipelines and the two second pipelines; fixing grooves are formed in the inner sides of the ends of the first pipeline and the second pipeline, and guiding mechanisms are installed on the inner sides of the fixing grooves. The water and electricity heating pipeline rapid connecting and fixing structure convenient to install is arranged at the bent position when a water and electricity heating pipe is laid, the included angle of the connecting and fixing structure can be adjusted according to the laying bent angle, then pipeline laying of different requirements is met, and therefore the phenomenon that in the follow-up overhaul process, the pipeline is pulled, and consequently friction is large, and serious damage is caused can be avoided.

The utility model discloses a miniature toggle switch, comprising a miniature toggle switch body which is provided with a switch bottom cooperation assembly, a conduction sheet A, a conduction sheet B, a conduction sheet C, a switch upper cooperation assembly and a switch pressing cover. The conduction piece A, the conduction piece B and the conduction piece C are arranged in the switch bottom matching assembly and the switch upper matching assembly in a matched mode, side stoppers are arranged on the two sides of the switch bottom matching assembly, the side stoppers and the switch bottom matching assembly are of an integrated structure, clamping blocks are arranged on the outer walls of the side stoppers, an isolation block is arranged in the center of the interior of the switch bottom matching assembly, and the isolation block is arranged in the middle of the switch bottom matching assembly. And the conduction sheet A and the conduction sheet C are cooperatively arranged on two sides of the conduction sheet B. The miniature toggle switch body 1 is small in overall size, the internal structure of the switch is simple, and the conduction sheet C and the conduction sheet A which are installed in a high-low staggered manner can realize different conduction effects through two times of pressing, so that the internal structure of the switch is greatly simplified, and the stability of the switch is improved.

The utility model belongs to the technical field of window sash positioning and limiting supports, and particularly relates to an angle-adjustable limiting support which comprises a plug, a positioning mechanism and an angle adjusting mechanism, the positioning mechanism comprises a clamping spring, the clamping spring is movably installed in a bottom groove, the bottom groove is formed by arranging limiting sealing edges on the tops of supporting plates on the two sides, and the clamping spring is shaped like a Chinese character'fang '. The two side edges of the clamping spring are designed to protrude inwards, and a fixing hole is formed in the middle of the left end of the clamping spring. According to the angle-adjustable limiting support, through the design of the positioning mechanism, when a window sash is opened or closed, the sliding code enters or is pushed out of the clamping spring, the structure is convenient to operate, the knob does not need to be manually rotated, meanwhile, the clamping spring structure is adopted, and the positioning force can reach 40N through the structure by utilizing the two bosses and the straight body position of the clamping spring to collide with the wall of the bottom groove. The window sash is not easy to close under the action of external force, has a certain limiting effect, and can be smoothly closed under the operation of people.
