Description

Technical Field

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

[0002] A floodlight is a lamp with a higher illuminance on the designated illuminated surface than the surrounding environment. It is also called a spotlight. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-area work sites and mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting lamps used outdoors can be regarded as floodlights.

[0003] When using a floodlight, the floodlight and the lamp stand can rotate about a fixed axis, so that the floodlight can only rotate about a fixed axis at a certain point, which limits the illumination angle of the floodlight, and makes the rotation angle of the floodlight not flexible enough, and cannot be universally rotated, and also makes the floodlight unable to adjust the angle in a wide range. Moreover, the distance between the floodlight and the lamp stand is small, which brings inconvenience to the adjustment of the illumination angle. Summary of the invention

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0019] like Figure 1-3As shown, a multi-directionally rotatable LED floodlight comprises a floodlight body 1 and a lamp stand;

[0020] The lamp stand comprises two bases 2, the upper ends of the two bases are fixedly connected to the bracket 3, the upper end of the bracket is fixed with a column 4, the column is rotatably connected to the mounting shell 6 through a bearing 5, and an angle locking structure is installed in the mounting shell;

[0021] The mounting shell is U-shaped, and two sides of the floodlight body are connected to the mounting shell via a rotating structure.

[0022] In this way, the base of the lamp stand can be fixed at the position where it needs to be installed, or it can be squatted at the position where it needs to be used. Brackets are fixed on the two bases to improve stability. The angle of the floodlight body can be rotated relative to the mounting shell, and the mounting shell can be rotated relative to the bracket to achieve multi-directional rotation of the floodlight body. After rotating in place, the position can be locked through the angle locking structure and the rotation structure.

[0023] During implementation, the rotating structure includes a support 7 fixedly mounted on both sides of the floodlight body, the support is provided with an internal threaded hole, the mounting shell is provided with a clearance hole opposite to the internal threaded hole, and the mounting shell is connected to the support by a locking bolt 8. Loosen the locking bolt, and the floodlight body can rotate relative to the support. After rotating in place, tighten the locking bolt, and the locking bolt is squeezed with the mounting shell to fix the angle of the floodlight body.

[0024] During implementation, the mounting shell includes a first half shell 9 and a second half shell 10, wherein the first half shell and the second half shell are provided with through holes facing each other, and the bolts 11 pass through the through holes of the first half shell and the second half shell and are connected with nuts, so as to facilitate the installation of the angle locking structure.

[0025] During implementation, the angle locking structure includes a gear 12 fixedly mounted on a column, the gear is located in a mounting shell, through holes are opened and closed on both sides of the mounting shell, a slider 13 is slidably fitted at the through hole, a connecting plate 14 is fixed to the end of the slider located in the mounting shell, a transmission rod 15 is fixed to the connecting plate, a locking block 16 is fixed to the end of the transmission rod, and the locking block is provided with a gear ring 17 meshing with the gear. When the angle needs to be adjusted, the two sides of the mounting shell are held in both directions, the slider is installed inward, the transmission rod and the locking block are driven to move by the connecting plate, the locking block is away from the gear, and then the mounting shell is rotated. By setting the sliders on both sides of the mounting shell, it is convenient to hold and rotate, and there is no need to put fingers under the floodlight body, which is easy to operate.

[0026] During implementation, a slot 18 is provided in the installation shell, a limit plate 19 is inserted in the slot, a sliding hole is provided on the limit plate to slide with the transmission rod, a compression spring 20 is provided between the limit plate and the locking block, and the compression spring is sleeved on the outside of the transmission rod. After the installation shell is rotated into place, the slider is released, the compression spring is reset, and the locking block is driven to mesh with the gear, thereby locking the installation shell relative to the bracket.

[0027] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
