Technical Field

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

[0002] Floodlights are widely used and can be used in many places such as tunnels, outdoor construction, landscape lighting, etc. Floodlights are equipped with brackets. In the prior art, the brackets are usually directly mounted on the lamp body, such as a Chinese patent with publication number CN213394869U, which discloses a floodlight and a bracket structure for positioning the floodlight. The lamp body can rotate around the bracket, but the disadvantage is that the bracket is directly fixed on the lamp body, the irradiation angle of the lamp body is limited, and when the lamp body rotates, the friction between the lamp body and the bracket is prone to scratches and wear. Summary of the invention

[0003] In view of the above shortcomings, the purpose of the present invention is to provide a fixing structure of a bracket and a floodlight body to achieve 360° rotating light projection.

[0004] To this end, the utility model provides a fixing structure of a floodlight bracket and a lamp body, comprising a connecting component, wherein the connecting component is fixed on the lamp body of the floodlight, and the connecting component comprises at least one connecting surface suitable for connecting to the bracket, wherein the connecting surface protrudes from the surface of the lamp body, and the bracket is movably connected to the connecting surface so that the lamp body can rotate relative to the bracket.

[0005] Furthermore, the connection surface is arranged on a connection plate, a gap is arranged between the connection plate and the surface of the lamp body, and the bracket is connected to the connection plate.

[0006] Furthermore, the connecting assembly is a U-shaped plate, including a wing plate suitable for fixing to the lamp body, a connecting plate suitable for connecting to the bracket, and a transition section connecting the wing plate and the connecting plate.

[0007] Furthermore, cover plates are provided on both sides of the connecting plate to cover the gap between the connecting plate and the lamp body.

[0008] Furthermore, the connection assembly is formed by integrally bending a cross-shaped plate to form a wing plate, a transition section, a connection plate and a cover plate.

[0009] Furthermore, the wing plate and the lamp body are fixed by riveting.

[0010] Furthermore, a first connecting hole is provided at the end of the bracket, and a second connecting hole is provided on the connecting surface. Bolts pass through the first connecting hole and the second connecting hole to connect the bracket to the connecting surface. The extension line of the second connecting hole passes through the middle of the wide side of the lamp body, and the lamp body can rotate 360° relative to the bracket.

[0011] Furthermore, an angle scale is provided on the outer side of the connecting surface, which is suitable for displaying the angle of the lamp body relative to the bracket.

[0012] Furthermore, the angle scale is formed by a scale groove provided on the surface of the connection surface, and the scale groove is provided on the surface of the connection surface in an annular shape with the second connection hole as a circle.

[0013] The utility model also comprises a floodlight, comprising a lamp body, a bracket and the above-mentioned fixing structure for fixing the lamp body and the bracket.

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

[0015] (1) The lamp body of the floodlight of the present invention is connected to the bracket through a connecting assembly. The bracket and the connecting assembly can rotate relative to each other under a certain external force to adjust the projection angle of the floodlight. The connecting surface of the connecting assembly protrudes from the surface of the lamp body. Generally speaking, the shape of a floodlight is not a standard cylindrical shape, and the size of the mask part of the floodlight is usually larger. By setting the connecting assembly protruding from the side surface of the lamp body of the present invention, the lamp body is located inside the bracket during the rotation process, thereby realizing 360° rotation of the floodlight.

[0016] (2) In a specific embodiment of the present invention, the connecting assembly is a U-shaped plate, the wing plate and the lamp body are solid, and the connecting plate formed by bending outward is movably connected to the end of the bracket, so that relative rotation occurs between the bracket and the connecting assembly, thereby avoiding the adverse effects of friction on the lamp body caused by the relative rotation between the bracket and the lamp body, such as scratching and damaging the protective layer on the metal surface. If a movable connecting structure is set up, it will be detrimental to the sealing structure of the lamp body. Floodlights are usually set outdoors, and poor sealing is prone to rainwater leakage. In a specific embodiment of the present invention, the connecting assembly and the lamp body are fixedly connected, which is convenient for sealing and not prone to leakage.

[0017] (3) The connection surface of the utility model is provided with an angle scale, which can intuitively display the projection angle of the floodlight, making it easy to adjust the floodlight to a suitable angle, especially avoiding frequent angle adjustments during high-altitude installation.

DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] Reference Figure 1 The figure shows a floodlight, and the fixing structure of a floodlight bracket 2 and a lamp body 1 of the utility model includes a connecting component 3, the connecting component 3 is fixed on the side of the lamp body 1 of the floodlight, and the connecting component 3 includes at least one connecting surface 3011 suitable for connecting with the bracket 2, the connecting surface 3011 protrudes from the surface of the lamp body 1, and the bracket 2 is movably connected to the connecting surface 3011 so that the lamp body 1 can rotate relative to the bracket 2. The connecting component 3 can be a block, and the connecting surface 3011 is the surface of the block close to one side of the bracket 2. In the specific embodiment of the utility model, the connecting surface 3011 is provided on the connecting plate 301, and a gap 302 is provided between the connecting plate 301 and the surface of the lamp body 1, and the bracket 2 is connected to the connecting plate 301.

[0028] Figure 2 , Figure 3 , Figure 5 and Figure 6 The first embodiment of the fixing structure of the projection lamp bracket 2 and the lamp body 1 is shown. In the first embodiment, referring to Figure 4 , Figure 5 and Figure 6As shown, the connecting component 3 is a U-shaped plate formed by bending a metal sheet. The U-shaped plate is mirror-symmetrical as a whole. The two sides of the U-shaped opening are bent to form wing plates 303. The wing plates 303 cooperate with the side surface of the lamp body 1. The wing plates 303 and the side surface of the lamp body 1 are provided with through holes, which can be fixed by riveting, bolting, etc. A pad can be provided on the inner side of the outer shell of the lamp body 1 to prevent the anchor nails or bolts from directly acting on the outer shell of the lamp body 1. The inner side of the U-shaped opening is formed by bending the metal sheet to form a transition section 304 in the direction away from the wing plate 303. The rear end of the transition section 304 is bent to form a connecting plate 301 parallel to the side surface of the lamp body 1. The two ends of the bracket 2 are respectively provided with first connecting holes 201 and are connected to the connecting components 3 on both sides of the lamp body 1. The center of the connecting plate 301 is provided with a second connecting hole 305 for cooperating with the first connecting hole 201. The bolts pass through the first connecting hole 201 and the second connecting hole 305 and are fixed to the inner side of the connecting plate 301 with nuts. The ends of the connecting plate 301 and the bracket 2 are tightened by the bolts, and the surfaces of the connecting plate 301 and the surfaces of the bracket 2 are subjected to pressure against each other. The bracket 2 or the lamp body 1 is rotated by applying a certain force to overcome the friction between the connecting plate 301 and the surface of the bracket. At the same time, the friction force between the connecting plate 301 and the bracket 2 can enable the lamp body 1 to maintain an angle with the bracket 2 under the action of its own weight, and project light to a predetermined direction or angle.

[0029] In the above embodiment 1, referring to Figure 5 , Figure 6 and Figure 7 As shown, cover plates 306 are provided on both sides of the connecting plate 301 to cover the gap 302 between the connecting plate 301 and the lamp body 1, to reduce the entry of dust and other debris, and to improve the aesthetics. The cover plate 306 can be formed by bending a cross-shaped plate formed by cutting to form the wing plate 303, the transition section 304, the connecting plate 301 and the cover plate 306.

[0030] Reference Figure 1 As shown, the extension line of the second connecting hole 305 passes through the middle of the wide side of the lamp body 1, that is, the two ends of the flat lamp body 1 in the width direction are the same length away from the second connecting hole 305, and the distance between the bottom of the U-shaped bracket 2 and the second connecting hole 305 is greater than the length between the two ends of the lamp body 1 in the width direction and the second connecting hole 305, so that the lamp body 1 can be rotated 360° relative to the bracket 2.

[0031] Reference Figure 5As shown, an angle scale is provided on the outside of the connection surface 3011, which is suitable for displaying the angle of the lamp body 1 relative to the bracket 2. In this embodiment, the angle scale is formed by a scale groove 307 provided on the surface of the connection surface 3011. The scale groove 307 is arranged in a ring shape on the surface of the connection surface 3011 with the second connection hole 305 as the center. The long groove and the short groove are arranged at intervals in the scale groove 307. This embodiment facilitates the setting of the angle of the floodlight during installation. By observing the scale line, the angle between the floodlight body 1 and the bracket 2 can be determined or judged, so that the angle of the light projected by the floodlight can be determined more accurately or intuitively. Compared with the angle adjustment based on experience, the number of repeated adjustments can be effectively reduced, and the technical requirements of the construction personnel can also be significantly reduced.

[0032] Reference Figure 7 As shown, the second and third embodiments are basically the same as the second embodiment, and both use a connecting plate 301 away from the side surface of the lamp body 1 as a connecting point, and a gap 302 is provided between the connecting plate 301 and the side surface of the lamp body 1. The difference lies in the difference in the connection method between the connecting plate 301 and the lamp body 1. The second embodiment adopts the structure of the square frame 4 for connection as a whole, while the third embodiment adopts a connecting column to connect the lamp body 1 and the connecting surface 3011. It should be noted that the connection component 3 and the lamp body 1 of the first, second and third embodiments can be integrally formed.
