Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, in particular to a floodlight capable of shielding and protecting screws. Background Art

[0002] A floodlight is a lamp that provides a higher illuminance on a designated illuminated surface than the surrounding environment. It is also known as a spotlight. Typically, it can be aimed in any direction and is designed to be unaffected by weather conditions. It is primarily used in large-scale work areas and mines, building outlines, stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all large-area outdoor lighting fixtures can be considered floodlights. The beam angle of a floodlight can range from wide to narrow, ranging from 0° to 180°. Those with particularly narrow beams are called searchlights. A floodlight consists of three parts: optical, mechanical, and electrical components. The optical components primarily consist of the reflector and light-limiting screen. The mechanical components primarily consist of the housing, the focusing mechanism that secures and adjusts the light source, the fixture bracket and base, and a component with an angle indicator that adjusts the beam's direction. For most sealed floodlights, the mechanical components also include protective glass and various seals. Depending on the operating environment, some may also include a metal mesh cover. High-performance floodlights also include an air filter. The electrical components are mainly ballasts, capacitors and triggers.

[0003] Floodlights are composed of multiple components. During installation, the brackets are often positioned and fixed using simple bolt connections. However, due to the limited operating space, the nuts and bolts used for positioning are prone to misalignment, making it difficult to tighten them quickly. Therefore, to address this issue, we developed a floodlight with screw protection. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a floodlight that can shield and protect screws.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A floodlight capable of shielding and protecting screws comprises a lamp housing, an inner wall of which is mounted a lighting panel, two sides of the lamp housing are connected to U-shaped positioning frames, a limiting cover is placed inside the U-shaped positioning frame, a polygonal limiting hole is penetrated through the limiting cover, a positioning nut is placed inside the polygonal limiting hole, two U-shaped positioning frames are provided with positioning bolts on the sides away from each other, and the opposite sides of the two positioning bolts penetrate the U-shaped positioning frame and are threadedly connected to the positioning nuts.

[0007] Preferably, a plurality of mounting screw holes are provided on the outer side of one end of the lamp housing, and one end of the mounting screw hole passes through the lamp housing.

[0008] Preferably, a plurality of heat dissipation strips are connected to the top of one end of the lamp housing.

[0009] Preferably, a U-shaped bracket is sleeved on the outside of the two positioning bolts and on the side away from the two U-shaped positioning frames.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model uses the cooperation of the U-shaped bracket, the limiting cover, the lamp housing, the lighting lamp board, the positioning bolt, the positioning nut, the polygonal limiting hole and the U-shaped positioning frame to clamp the U-shaped bracket on the outside of the two U-shaped positioning frames, put the positioning nut into the polygonal limiting hole, and then insert the limiting cover into the U-shaped positioning frame. At this time, the positioning nut is restrained by the limiting cover, and the positioning bolt is used to penetrate the U-shaped bracket and rotate into the positioning nut to complete the positioning of the U-shaped bracket.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] See also Figure 1-Figure 2 A floodlight that can shield and protect screws includes a lamp housing 3, an inner wall of the lamp housing 3 is installed with a lighting lamp board 4, both sides of the lamp housing 3 are connected with U-shaped positioning frames 10, a limit cover 2 is placed inside the U-shaped positioning frame 10, a polygonal limit hole 9 is opened through the limit cover 2, a positioning nut 8 is placed inside the polygonal limit hole 9, and a positioning bolt 7 is provided on the side away from the two U-shaped positioning frames 10, and the opposite side of the two positioning bolts 7 passes through the U-shaped positioning frame 10 and is threadedly connected to the positioning nut 8.

[0017] As a technical optimization solution of the present invention, a plurality of mounting screw holes 5 are provided on the outer side of one end of the lamp housing 3, and one end of the mounting screw hole 5 passes through the lamp housing 3; a plurality of mounting screw holes 5 are also provided on the lighting lamp board 4, and through the mounting screw holes 5, the lamp housing 3 and the lighting lamp board 4 can be conveniently connected with bolts.

[0018] As a technical optimization solution of the present invention, a plurality of heat dissipation strips 6 are connected to the top of one end of the lamp housing 3 ; the heat dissipation strips 6 increase the heat dissipation area of the lamp housing 3 .

[0019] As a technical optimization solution of the present invention, a U-shaped bracket 1 is provided outside the two positioning bolts 7 and on the side away from the two U-shaped positioning frames 10; the U-shaped bracket 1 makes it convenient to lift and carry the translucent lamp.

[0020] When the present invention is in use, the U-shaped bracket 1 is clamped on the outside of the two U-shaped positioning frames 10, the positioning nut 8 is placed in the polygonal limiting hole 9, and then the limiting cover 2 is inserted into the U-shaped positioning frame 10. At this time, the positioning nut 8 is restrained by the limiting cover 2. At this time, the positioning bolt 7 is used to penetrate the U-shaped bracket 1 and rotate into the positioning nut 8 to complete the positioning of the U-shaped bracket 1. In this way, the positioning nut 8 is limited, so that the positioning nut 8 and the positioning bolt 7 can be better fixed and tightened. Furthermore, after the positioning nut 8 is shielded, it can avoid corrosion from rainwater, extend the life of the positioning nut 8, and avoid the loss of the positioning nut 8. If there is no limiting cover 2 during normal disassembly and assembly, it is easy to fall and be lost. Furthermore, the use of the limiting cover 2 can cover the cavity, making the floodlight more beautiful.

[0021] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
