Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a power supply box convenient to install comprises a power supply box body 1 and a U-shaped installation seat 4, wherein rotating rods 6 are arranged at four corners of an inner cavity of the installation seat 4, the rotating rods 6 are rotatably connected with the inner surface wall of the bottom of the installation seat 4 through bearings, worm wheels 14 are sleeved outside the four rotating rods 6, two worms 13 in the horizontal direction are arranged in the inner cavity of the installation seat 4, the worm wheels 14 are connected with the worms 13 in a meshed mode, the two worms 13 are connected through a belt 12 in a transmission mode, belt pulleys are installed on the two worms 13, simultaneous rotation of the two worms 13 is realized, the four rotating rods 6 penetrate through the inner surface wall of the top of the installation seat 4 and are fixedly provided with limiting blocks 2, the rotating rods 6 can drive the limiting blocks 2 to rotate, four connecting blocks 9 are fixed on the outer surface walls of the front end and the rear end of the power supply box body 1, through holes 5 are formed in the four connecting blocks 9, the through, the through hole 5 and the limiting block 2 are coaxially distributed, and the area of the through hole 5 is larger than that of the limiting block 2.

Specifically, as shown in fig. 1, the upper surface wall of the mounting seat 4 is elastically connected with a top plate 11 through a spring 7, the spring 7 can give the top plate 11 elastic force in the vertical direction, and the top plate 11 can enable the power box body 1 to move upwards under the elastic force, so that the upper surface wall of the connecting block 9 is attached to the lower surface wall of the limiting block 2, and the loosening of the power box body 1 is effectively prevented.

Specifically, as shown in fig. 1, a telescopic rod 8 for preventing the spring 7 from deviating is arranged inside the spring 7, and the telescopic rod 8 can prevent the spring 7 from deviating in the process of stretching.

Specifically, as shown in fig. 3 and 4, dovetail-shaped limiting grooves 15 are formed in the inner surface walls of the two sides of the mounting seat 4, protrusions 3 engaged with the limiting grooves 15 are fixed on the outer surface walls of the two sides of the power box body 1, the protrusions 3 are identical to the limiting grooves 15 in shape, and the power box body 1 is limited horizontally and longitudinally by the engagement of the protrusions 3 and the limiting grooves 15.
