Description

Technical Field

[0001] The utility model relates to a bracket structure of a floodlight, and also relates to a floodlight structure comprising the bracket. Background Art

[0002] The floodlight bracket is used to install or fix the floodlight in a predetermined position, so that the floodlight can stably project the light beam to the predetermined area to realize the function of the lighting lamp. In the prior art, the bracket is usually directly installed on the lamp body, such as a floodlight and a bracket structure for positioning the floodlight disclosed in the Chinese patent with publication number CN213394869U. The disadvantage is that the relative rotation angle of the lamp body in the prior art is limited, and certain position requirements need to be met during installation to meet the coverage of the predetermined area, and the requirements for installation are more stringent. In addition, especially when working at high altitude, when the bracket is installed on the thicker wall on the other side, bolts need to be installed from the inside of the bracket to the wall. The space between the bracket and the lamp body is limited, which makes the installation very inconvenient. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the present invention is to provide a floodlight bracket that can be adjusted more flexibly. The purpose of the present invention is also to provide a floodlight including the above-mentioned floodlight bracket.

[0004] To this end, the utility model provides a bracket for a floodlight, including a U-shaped bracket body, and also including connecting holes connected to both ends of the bracket body for rotatably connecting with a connecting assembly, the connecting holes are located on the same axis perpendicular to the side strips of the bracket body, the connecting assembly includes a protrusion, and the connecting surface between the protrusion and the bracket body is located on the outside of the side surface of the floodlight body.

[0005] Furthermore, the connecting assembly includes a U-shaped plate, which includes a wing plate suitable for fixing to the lamp body, a connecting plate connected to the bracket body, and a transition section connecting the wing plate and the connecting plate, and also includes a cover plate arranged on the upper and lower sides of the U-shaped plate.

[0006] Furthermore, a scale groove is provided on the connecting plate for displaying the angle between the lamp body of the floodlight and the bracket body.

[0007] Furthermore, the support body includes a bottom horizontal bar and the side bars, and the horizontal bar is arranged obliquely.

[0008] Furthermore, a plurality of through holes are arranged on the horizontal bar.

[0009] The utility model also includes a floodlight, comprising the above-mentioned floodlight bracket, a lamp body shell, a light-transmitting mask, a reflective component and a light source, wherein the light-transmitting mask, the reflective plate and the light source are installed on the lamp body shell from outside to inside.

[0010] Furthermore, a cavity is provided inside the shell, and the reflective assembly includes a base plate and an arc-shaped reflective plate. The base plate is provided with a limiting protrusion, and the limiting protrusion cooperates with the shell and the light-transmitting mask to fix the reflective plate in the cavity. The base plate is provided with a window, and the light source is arranged in an array on the mounting plate facing the window.

[0011] Furthermore, it also includes a fixing plate, which includes a longitudinal plate and a transverse plate formed by partial bending, the longitudinal plate is fixed to the side wall of the lamp body shell, and the transverse plate is used to be fixed to the mounting plate.

[0012] Furthermore, a polygonal hole is provided on the longitudinal plate, the side wall and the longitudinal plate are fixed by bolts and nuts, the bolts have a cylindrical surface matching the polygonal hole for limiting the rotation of the longitudinal plate, and the transverse plate and the mounting plate are fixed by bolt fasteners.

[0013] Furthermore, a plurality of strip-shaped reinforcing ribs are provided on the bottom and side surfaces of the lamp body shell.

[0014] The beneficial effects of the utility model are:

[0015] (1) The bracket of the utility model includes a connecting assembly, and the connecting assembly includes a protruding portion. The protruding degree of the protruding portion is such that when the lamp body of the floodlight rotates, the outer shell of the lamp body is on the inner side of the U-shaped bracket body, thereby realizing 360° rotation. Specifically, the connecting assembly adopts a plate that is integrally bent to form a wing plate, a transition section and a connecting plate. The wing plate is connected to the outer shell of the lamp body, and the connecting plate is connected to the bracket. The bracket and the outer shell of the lamp body are not directly connected. Since the bracket and the lamp body need to be rotated and adjusted, the specific scheme of the utility model is adopted, which is also conducive to reducing the difficulty of sealing the outer shell of the lamp body and improving the service life of the sealing structure of the lamp body.

[0016] (2) In a specific embodiment of the utility model, the bracket includes a bottom horizontal bar that is inclined. When installation is required from the inner side of the bottom horizontal bar, the inclined horizontal bar changes the angle of the mounting bolts, making it easier to fix the horizontal bar from the outside of the lamp body using larger tools such as electric tools. In addition, when the floodlight is placed directly on the ground, the inclined bottom horizontal bar can be in contact with the ground, thereby improving its stability.

[0017] (3) The floodlight of the utility model uses a fixing plate to detachably fix the light source mounting plate and the outer shell, which is convenient for replacement and prevents water seepage from directly affecting the light source when the sealing structure fails. In the specific embodiment of the utility model, reinforcing ribs are also provided, which not only strengthen the strength of the lamp body outer shell, but also increase the contact area with the outside world, thereby improving the heat dissipation effect.
