[0035] In the embodiment of the utility model, this case provides an anti-dropping LED power box for locking the circuit board 120, which is characterized by comprising a bottom plate 100 and a cover plate 200, the bottom plate 100 extends upwardly to form two bottom plates 100 on both sides in the length direction, and the cover plate 200 extends downwardly to form two cover plates 210 on both sides in the length direction, the cover plate 200 covers the bottom plate 100 and is slidably connected thereto, and the bottom plate 100 is fixedly provided with abutments 300 on the front and rear opening ends, and the cover plate 200, the bottom plate 100 and the two abutments 300 cooperate with each other A closed inner chamber cavity 310 is formed; the bottom plate 100 is provided with a cylindrical member 400 with a threaded structure and an opening facing upward, and the cylindrical member 400 extends upward and passes through the center position of the circuit board 120, and is used to support the circuit board 120; a locking member 410 passes through the circuit board 120 from top to bottom and extends into the cylindrical member 400 to lock the circuit board 120; a boss 700 is provided at the upper end of the abutment member 300, and an embedding opening 710 is provided at a corresponding position of the cover plate 200, and the boss 700 extends into the embedding opening 710 to limit the movement of the cover plate 200.

[0036] Specifically, the abutment member 300 abuts against the side bottom plate 110 to prevent the side bottom plate 110 from shaking. The locking member 410 penetrates the circuit board 120 from top to bottom and extends into the cylindrical member 400. The cylindrical member 400 preferably adopts a rivet pin to ensure that the circuit board 120 is firmly fixed on the bottom plate 100 to prevent the circuit board 120 from loosening or falling off due to vibration or movement. Riveting is achieved by fixing rivets on the workpiece and connecting through fracturing and deformation. This connection method can provide high strength and can withstand large tensile and shear forces, so it is widely used in many high-strength applications. The sliding connection design between the cover plate 200 and the bottom plate 100 makes the switch of the power box more convenient, and can better close the inner chamber 310, thereby improving the safety and stability of the power box. The cylindrical member 400 with a threaded structure and an upward opening on the bottom plate 100, and the locking member 410 on the cylindrical member 400 can effectively support the circuit board 120 and keep its position stable, thereby increasing the stability and reliability of the circuit board 120. After assembly, it is fixed by PCB+screws. The locking member 410 tightly connects the bottom plate 100 and the abutment member 300, reducing the gap and the risk of glue leakage. The boss 700 on the abutment member 300 and the embedded opening 710 on the cover plate 200 cooperate with each other to limit the movement of the cover plate 200 and ensure that the cover plate 200 is in the correct position, thereby further improving the stability and safety of the power box.

[0037] In another embodiment of the utility model, the bottom end and the outer side walls of the left and right ends of the abutment 300 are provided with glue guide grooves 320, and the glue guide grooves 340 are parallel to the abutment 300. Specifically, the power box needs to be filled with AB glue between the PCB circuit board 120 and the bottom plate 100. The AB glue is liquid before curing. A small amount of AB glue will overflow before filling the glue, and the overflowed AB glue will first flow into the glue guide grooves 320 and can be removed after curing. The glue guide grooves 320 are provided to prevent sporadic glue leakage and facilitate cleaning.

[0038] In another embodiment of the utility model, a semicircular guide rail 500 protruding outward is provided on the outer side wall of the side bottom plate 110, and a semicircular slider 510 recessed inward is provided on the inner side wall of the side cover plate 210, and the semicircular slider 510 slides on the semicircular guide rail 500. Specifically, the semicircular slider 510 slides on the semicircular guide rail 500, that is, slides between the cover plate 200 and the bottom plate 100, and after the user releases the connection between the boss 700 and the embedding opening 710, the cover plate 200 can be slid out along the guide rail of the side bottom plate 110, thereby enhancing the smoothness and user experience.

[0039] In another embodiment of the utility model, a support slide 520 parallel to the semicircular guide rail 500 is also provided on the outer side wall of the side bottom plate 110, and the support slide 520 is located at the lower end of the side bottom plate 110 and abuts against it. Specifically, in general, the power box is made of polyester and other materials with a certain degree of deformation ability. When the side cover plate 210 and the side bottom plate 110 slide by the limited position between the semicircular slider 510 and the semicircular slide rail, they will be separated due to the deformation ability. Therefore, a support slide 520 is provided at the lower end of the semicircular guide rail 500, which generates an upward abutting force on the side cover plate 210, effectively preventing the slide rail from being separated.

[0040] In another embodiment of the utility model, a wire hole 600 is formed between the abutment member 300 and the cover plate 200 for guiding the wires of the power box.

[0041] In another embodiment of the utility model, a locking edge 800 is extended forward in the width direction of the base plate 100, and a plurality of mounting holes 810 are provided on the locking edge 800, which means that the LED power box can be flush, symmetrical or focused and locked.

[0042] In another embodiment of the utility model, a plurality of convex grooves 900 are further provided on the outer side wall of the side bottom plate 110. The convex grooves 900 are streamlined in design, which are more comfortable for the user to hold.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
