Description

Technical Field

[0001] This application relates to the field of power distribution equipment operation and maintenance technology, specifically a multi-angle adjustable LED floodlight with a simple locking device. Background Technology

[0002] After the power distribution equipment is installed, LED floodlights are often installed next to it to improve the convenience of operation and maintenance. LED floodlights use LEDs (light-emitting diodes) as the light source, a type of solid-state semiconductor device with advantages such as energy saving, environmental friendliness, and long lifespan. LED floodlights are controlled by a built-in microchip, allowing the illumination range to be adjusted according to the installation location of the power distribution equipment, thus achieving precise lighting. Furthermore, existing LED floodlights can be configured with different brackets according to the usage environment and requirements, enabling convenient tilt adjustment and simplifying installation.

[0003] However, existing LED floodlights need to be exposed to the outdoors for extended periods of time, and their waterproof and dustproof performance is poor. At the same time, their adjustability is also poor. Existing LED floodlights can only make simple tilt adjustments, and when the installation location is limited, it is difficult for them to provide precise lighting. Utility Model Content

[0004] This application provides a multi-angle adjustable LED floodlight with a simple locking device, which can be rotated and tilted and fixed in position, so that the light beam projected by the LED floodlight can accurately illuminate the power distribution equipment, which facilitates the operation and maintenance personnel to inspect the power distribution equipment and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a multi-angle adjustable LED floodlight with a simple locking device, including an annular mounting base, the interior of which is provided with a waterproof box, the outer side of the annular mounting base is provided with an inner annular groove and an outer annular groove on its inner and outer sides respectively, the inner side of the outer annular groove is provided with annular teeth, and at least one arc-shaped slider is slidably connected to the upper end of the outer side of the annular mounting base, the arc-shaped slider being fixed inside the outer annular groove by a positioning screw.

[0006] The upper surface of the arc-shaped slider is provided with a mounting base, which is connected to a rotating bracket by positioning bolts. A metal frame is mounted on the rotating bracket, and LED integrated lamp beads are installed inside the metal frame. A glass plate is provided on the outer end of the metal frame, and a lifting cover plate is covered on the glass plate. An annular silicone ring is provided on the outer edge of the lifting cover plate. The lifting cover plate is connected to the telescopic end of the electrically controlled telescopic rod through a connecting plate. The electrically controlled telescopic rod is installed on the outer side of the metal frame.

[0007] Preferably, the lower end of the outer side of the annular mounting base is provided with an annular mounting plate, and the upper surface of the annular mounting plate is provided with at least one arc-shaped mounting groove.

[0008] Preferably, the bottom of the inner side of the annular mounting base is provided with an internal threaded hole, through which a screw passes to fix the waterproof box inside the annular mounting base. The outer side of the waterproof box is provided with a wiring hole, and a removable sealing cover is installed on the upper surface of the waterproof box. The inside of the waterproof box is provided with a controller and a wiring socket.

[0009] Preferably, the outer side of the annular mounting base is provided with at least one lead wire groove.

[0010] Preferably, the rotating bracket is welded to the screw of the positioning bolt, the screw of the positioning bolt passes through the positioning hole on the mounting base, and the outer side of the mounting base is provided with annular anti-slip teeth near the positioning hole.

[0011] Preferably, the outer surface of the metal frame is provided with heat dissipation strips.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. This application allows for rotation and pitch adjustment as well as position fixation, enabling the light beam projected by the LED floodlight to accurately illuminate the power distribution equipment, facilitating maintenance personnel to inspect the power distribution equipment;

[0014] 2. Loosen the positioning screw to adjust the position of the arc-shaped slider. Once the arc-shaped slider is in place, screw the bottom of the positioning screw back into the groove of the ring tooth. The ring silicone ring is tightly attached to the outer side of the glass plate. When the LED light is not in use, the lifting cover plate covers the glass plate, which can reduce the accumulation of dust. At the same time, as the ring silicone ring moves up and down with the lifting cover plate, it can wipe the surface of the glass plate, effectively ensuring the illumination effect of the LED light.

[0015] 3. When installing the lead wire, open the sealing cover and pass the wire through the wiring hole into the interior of the waterproof box. Then fix the end of the wire to the terminal block, seal the wiring hole with sealant, and finally reinstall the sealing cover. This effectively improves the overall waterproofness of the equipment.
