Description

Technical Field

[0001] This utility model relates to the field of LED floodlight technology, specifically to an installation structure for LED floodlights. Background Technology

[0002] A floodlight is a lighting fixture that provides illumination to a surface that is higher than the surrounding environment. Also known as a spotlight, it is mainly used for large-area work sites, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights. Floodlights have varying beam angles, ranging from 0° to 180°. Those with particularly narrow beams are called searchlights.

[0003] The existing floodlight installation structure is usually a U-shaped bracket hinged to the floodlight body, which is fixed to the wall with screws. This installation method is simple and quick, but it also has some drawbacks. Although the floodlight body can rotate, it can only change the pitch angle and cannot change the horizontal direction. The floodlight body can only face straight ahead, which is still a limitation. In addition, the floodlight body and the U-shaped bracket cannot be separated. When it is necessary to inspect the floodlight body, it is either necessary to climb up or remove the U-shaped bracket from the wall, which is quite inconvenient. Utility Model Content

[0004] This invention provides an installation structure for LED floodlights to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for an LED floodlight, comprising a floodlight body and an adjustment bracket, wherein the floodlight body is clamped on the adjustment bracket; the adjustment bracket comprises a base, an axial damping shaft, a rotating frame, a radial damping shaft, a connecting block, a screw, and a clamping plate; the axial damping shaft is mounted on the base; the rotating frame is hinged to the base via the axial damping shaft; the radial damping shaft is mounted on both sides of the rotating frame; the connecting block is hinged to both sides of the rotating frame via the radial damping shaft; one end of the screw is threadedly connected to the connecting block, and the other end of the screw is threadedly connected to the clamping plate.

[0006] Furthermore, the base is provided with fixing holes around its perimeter, and the axial damping shaft is located in the middle of the base.

[0007] Furthermore, a rubber pad is installed in the middle of the base, and the rubber pad is located between the base and the rotating frame.

[0008] Furthermore, a tightening nut is threaded onto the screw, and the tightening nut is located on both sides of the clamping plate.

[0009] Furthermore, the upper part of the clamp is provided with a slot, and it is engaged with the side of the floodlight body through the slot.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3This utility model discloses an installation structure for an LED floodlight, including a floodlight body 1 and an adjustment bracket 2. The floodlight body 1 is clamped on the adjustment bracket 2. An axial damping shaft 22 and a radial damping shaft 24 are provided in the adjustment bracket 2. The orientation of the clamping part of the adjustment bracket 2 can be changed by the characteristics of the damping shaft, so that the floodlight can not only adjust the pitch angle up and down, but also adjust the illumination angle in the circumference, thereby improving the flexibility of the floodlight. At the same time, the cooperation of the clamping plate 27 and the screw 26 not only facilitates the disassembly, assembly and maintenance of the floodlight, but also can be adapted to the use of floodlights of different sizes of the same type.

[0019] The adjusting bracket 2 includes a base 21, an axial damping shaft 22, a rotating frame 23, a radial damping shaft 24, a connecting block 25, a screw 26, and a clamping plate 27. The axial damping shaft 22 is mounted on the base 21. The rotating frame 23 is hinged to the base 21 via the axial damping shaft 22. The radial damping shaft 24 is mounted on both sides of the rotating frame 23. The connecting block 25 is hinged to both sides of the rotating frame 23 via the radial damping shaft 24. One end of the screw 26 is threadedly connected to the connecting block 25, and the other end of the screw 26 is threadedly connected to the clamping plate 27.

[0020] Specifically, the base 21 is provided with fixing holes 28 around its perimeter, and the axial damping shaft 22 is located in the middle of the base 21.

[0021] In this embodiment, the fixing hole 28 is used to fit the bolt, so that the adjusting bracket 2 is fixed to the wall or other object. The axial damping shaft 22 and the radial damping shaft 24 are defined as shafts that must be used to connect product parts and are used to withstand both bending moment and torque during rotation. The principle of the damping shaft is actually to generate friction through the compression between the shims. The magnitude of the friction depends on the number of shims installed and the tightness of the nuts. For example, the hinge used in a laptop requires a certain amount of force when we open the laptop screen, but this force does not need to be very large. When we stop flipping, the screen will not sway up, down, left, or right and fall down. Instead, the laptop screen is kept in the desired position by the friction on the hinge.

[0022] Specifically, a rubber pad 29 is installed in the middle of the base 21, and the rubber pad 29 is located between the base 21 and the rotating frame 23.

[0023] In this embodiment, the rubber pad 29 has excellent wear resistance due to its superior elasticity and toughness. It is placed between the base 21 and the rotating frame 23 to reduce wear between the two.

[0024] Specifically, a tensioning nut 210 is threaded onto the screw 26, and the tensioning nut 210 is located on both sides of the clamping plate 27.

[0025] This implementation plan, such as Figure 3 As shown, the tightening nut 210 is used to limit the position of the clamp 27.

[0026] Specifically, the upper part of the clamping plate 27 is provided with a slot 211, and it is engaged with the side of the floodlight body 1 through the slot 211.

[0027] In this embodiment, the slot 211 is used to engage the clamp 27 with the side of the floodlight body 1, thereby enabling the installation and fixation of the floodlight body 1.

[0028] Specifically, the clamping plate 27 is located on the left and right sides of the floodlight body 1, and a rubber sheet 212 is pasted in the slot 211.

[0029] In this embodiment, the rubber sheet 212 has a certain elasticity and toughness, which can fill the gap between the slot 211 and the side of the floodlight body 1, thereby providing reliable assembly between the slot 211 and the side of the floodlight body 1.

[0030] In use, the adjusting bracket 2 is equipped with an axial damping shaft 22 and a radial damping shaft 24. The characteristics of the damping shaft can change the orientation of the clamping part of the adjusting bracket 2, so that the floodlight can not only adjust the pitch angle up and down, but also adjust the illumination angle in the circumference, thereby improving the flexibility of the floodlight. At the same time, through the cooperation of the clamping plate 27 and the screw 26 (the clamping plate 27 clamps on both sides of the floodlight body 1 to realize the installation and fixation of the floodlight body 1, and because it is clamped and fixed, it is easier to disassemble and assemble during inspection and maintenance, and the clamping plate 27 can be moved along the path of the screw 26 to adjust its clamping distance), it is not only convenient for the disassembly and maintenance of the floodlight, but also adaptable to the use of floodlights of different sizes of the same type.

[0031] In summary, the installation structure of this LED floodlight includes an axial damping shaft 22 and a radial damping shaft 24 in the adjustment bracket 2. The characteristics of the damping shafts can change the orientation of the clamping part of the adjustment bracket 2, allowing the floodlight to not only adjust its pitch angle vertically but also its illumination angle circumferentially, thereby improving the flexibility of the floodlight. At the same time, the cooperation of the clamping plate 27 and the screw 26 not only facilitates the disassembly, assembly, and maintenance of the floodlight but also allows it to be used with floodlights of the same type but different sizes.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
