Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, in particular to an LED floodlight that can be adjusted in multiple directions. Background Art

[0002] A floodlight is a lighting fixture that specifies a higher illuminance on the illuminated surface than the surrounding environment, also known as a spotlight. Usually, it can aim in any direction and has a structure that is not affected by weather conditions. It is mainly used in large-area working sites, building outlines, stadiums, overpasses, monuments, parks, flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The exit beam angle of the floodlight is wide or narrow, and the variation range is between 0° and 180°. Among them, the floodlight with a particularly narrow beam is called a searchlight.

[0003] The patent with the publication number of CN220911179U discloses a glare-proof floodlight for stadiums, including a weighted base. The top of the weighted base is fixedly connected with two connecting plates. A connecting block is rotatably connected between the two connecting plates through a damping rotating shaft. One side of the connecting block is rotatably connected with a mounting plate through a damping shaft. Two sliding holes are opened on one side of the mounting plate. Two sliding blocks are slidably connected through the two sliding holes. A glare-proof floodlight body is arranged on the side of the sliding block away from the connecting block. This utility model is simple to use. The flat lamp shade is a detachable structure, which facilitates the maintenance of the glare-proof floodlight body. After turning the nut to move the glare-proof floodlight body, the light distribution of multiple glare-proof floodlight bodies can be adjusted. The wires can be sorted out through the through pipe and then connected to the glare-proof floodlight body. The weighted base adopts a weighted design and is more difficult to topple over and can be adsorbed by a magnetic plate to prevent movement.

[0004] The structures of the above-disclosed floodlights are complex, inconvenient to adjust the deflection angle, and cannot quickly disassemble, assemble, and repair the equipment according to actual needs. It is time-consuming and laborious and not easy to maintain. Therefore, an LED floodlight that can be adjusted in multiple directions is designed here to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an LED floodlight that can be adjusted in multiple directions in order to solve the problems that the structure of the traditional floodlight is complex, inconvenient to adjust the deflection angle, and cannot quickly disassemble, assemble, and repair the equipment according to actual needs, which is time-consuming and laborious and not easy to maintain.

[0006] To achieve the above object, the technical solution of the present utility model is: an LED floodlight that can be adjusted in multiple directions, including a splicing base one and a splicing base two that are spliced with each other. An insertion block is fixedly arranged inside the splicing base two, and an installation cavity that cooperates with the insertion block is opened on the inner wall of the splicing base one; a swinging seat that cooperates with each other is arranged on the splicing base one and the splicing base two. A swinging cavity is opened on the swinging seat, and a lamp holder is movably installed between the swinging cavities. A swinging column that cooperates with the swinging cavity is fixedly arranged on the back of the lamp holder; a cavity is opened inside one group of the swinging columns, a through hole is opened through the swinging column, the through hole communicates with the cavity, a sliding rod is movably arranged inside the through hole, and a plug that cooperates with the sliding rod is installed by threading inside the cavity; fixing plates are arranged at the bottoms of the splicing base one and the splicing base two. Two groups of bolts are installed by threading on the fixing plates, and the fixing plates are movably connected to the splicing base one and the splicing base two through the bolts. Positioning holes that cooperate with the sliding rod are opened on the inner wall of the swinging cavity.

[0007] As a further scheme of the present invention: a fixing seat is arranged at the top of the fixing plate.

[0008] As a further scheme of the present invention: multiple groups of slotted holes are opened on the upper and lower sides of the insertion block, positioning springs are arranged inside the slotted holes, and balls are arranged at the tops of the positioning springs; grooves that cooperate with the balls are opened on the upper and lower inner walls of the installation cavity.

[0009] As a further scheme of the present invention: reset grooves are opened on both sides of the through hole, symmetric convex platforms are arranged on the outer walls of both sides of the sliding rod, a reset spring is connected to the convex platform, and the top of the reset spring is connected to the top of the reset groove.

[0010] As a further scheme of the present utility model: an extrusion part is arranged at the bottom of the sliding rod, an inclined part is arranged at the front end of the plug, and a screwing part is fixedly arranged on the outside of the plug.

[0011] As a further scheme of the present utility model: multiple groups of bulbs are installed on the lamp holder, a sliding groove is opened on the lamp holder, and a lamp shade is movably installed inside the sliding groove.

[0012] Compared with the prior art, the present utility model has the following improvements and advantages:

[0013] This utility model utilizes detachable splicing bases 1 and 2 to quickly assemble and disassemble the lamp holder. Furthermore, the screw plug and sliding rod cooperate to freely adjust the lamp holder's swing angle. When the screw plug rotates inward, the inclined portion presses the extrusion portion upward, causing the sliding rod to move upward along the through-hole and insert into the positioning hole. This ingenious and effective design significantly enhances the stability and practicality of this multi-directionally adjustable LED floodlight. BRIEF DESCRIPTION OF THE DRAWINGS
