Description

Waterproof and dustproof structure of LED driving power supply Technical Field The utility model relates to the technical field of driving power supplies, in particular to a waterproof and dustproof structure of an LED driving power supply. Background The LED driving power supply is a power converter for converting power supply into specific voltage and current to drive the LED to emit light, and along with the wide application of LED lighting technology, the importance of the LED driving power supply in various lighting systems is increasingly highlighted, especially in the environment of outdoor lighting, industrial lighting and the like, the LED driving power supply faces serious challenges of water resistance and dust prevention. In the outdoor or moist, dusty environment of traditional LED drive power supply, moisture and dust invade inside the LED drive power supply easily, cause serious influence to its performance and life-span, consequently adopt the protecting crust to carry out waterproof dustproof to it more, but current protecting crust not only the connected mode complicacy to influence the heat dispersion of power, lead to the power overheated, reduction in service life. Disclosure of utility model The utility model aims to solve the technical problems that in the prior art, the waterproof and dustproof structure of the LED driving power supply is complex in operation and affects the heat dissipation of the power supply, and provides the waterproof and dustproof structure of the LED driving power supply. In order to achieve the aim, the LED driving power supply waterproof and dustproof structure comprises a bottom plate, wherein an installation seat is arranged at the top of the bottom plate, a power supply body is installed at the top of the installation seat, a shell seat is fixed at the top of the bottom plate and positioned at the outer side of the installation seat, a protection shell is installed at the top of the shell seat, fixing blocks are fixed on two sides of the protection shell, a shell is fixed on two sides of the shell seat, a push rod is connected with the side wall of the shell in a sliding mode, a lug is fixed at one end of the push rod positioned in the shell, a fixing plate provided with a rebound mechanism is connected with two sides of the shell in a sliding mode, a stress block is fixed on one side of the fixing plate, opposite faces of the stress block are in butt joint with two sides of the lug, a clamping block is fixed at the top of the fixing plate, and clamping grooves matched with the clamping block are formed in two sides of the fixing block. Preferably, the rebound mechanism comprises a first spring mounted on the other side of the fixing plate, and the other end of the first spring is fixed with the inside of the housing. Preferably, the two sides of the inside of the shell are both fixed with limiting rods, and the surface of the fixing plate is provided with through grooves matched with the limiting rods. Preferably, the opposite surfaces of the stress block are provided with inclined surfaces and are matched with two sides of the convex block. Preferably, a plurality of through holes are formed in the surface of the mounting seat and on two sides of the protective shell, and the through holes can form a complete heat dissipation channel.
