Abstract
Description
Technical Field
[0001] This utility model relates to the field of floodlight technology, and more specifically, to a C-shaped buckle reverse-pressure fixing structure for floodlight lens glass. Background Technology
[0002] A floodlight is a lighting device with a wide beam distribution and no obvious directional limitations. It can be used to create an overall lighting effect or to supplement the lighting of specific areas. Among them, LED floodlights are currently the most widely used type. They use light-emitting diodes as the light source and have advantages such as energy saving, environmental friendliness, long lifespan, fast response speed, small size, and light weight. Moreover, the brightness can be controlled by adjusting the current to achieve different lighting effects.
[0003] In practical use, LED floodlights typically consist of a back cover and a lens glass as the outer shell of the light body. The traditional method of locking the glass generally involves screws directly penetrating the lens glass and pressing it onto the back cover. In order to ensure the firmness of the installation, at least 8 screws are usually evenly distributed and installed on the edge of the lens glass.
[0004] However, existing LED floodlights still have many shortcomings in actual use. Because the contact area between the screw nut and the lens glass surface is small and the clamping force is large, stress concentration is likely to occur in local areas of the glass. When the glass temperature is high due to prolonged use of the light fixture, micro-cracks are likely to form on the glass, which can lead to glass damage. At the same time, since the screws are generally installed on the back cover from the bottom of the lens glass, when workers replace the lens glass of the light fixture installed at a high position, they need to operate from below the light fixture with their heads up and their hands raised, which makes the replacement difficult. Utility Model Content
[0005] This utility model provides a C-shaped buckle reverse-pressure fixing structure for floodlight lens glass, which aims to solve the following problems: Existing LED floodlights that use screws to fix the lens glass are prone to stress concentration in local areas of the glass. After long-term use, micro-cracks are easily generated on the glass, which can lead to glass damage. At the same time, since screws are generally installed on the back cover from the bottom of the lens glass, when workers replace the lens glass of the light fixture installed at a high position, they need to operate from below the light fixture with their heads up and their hands raised, which makes the replacement difficult.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a floodlight lens glass C-type buckle reverse pressure fixing structure, comprising: a floodlight body, the floodlight body including a back cover, the top of the back cover being provided with several connecting cylinders, and the bottom of the back cover being provided with a lens;
[0007] The back cover is equipped with a fixing mechanism, which includes several C-shaped buckles. The top of the C-shaped buckles has a through hole that fits the connecting tube.
[0008] In a preferred embodiment, the C-shaped buckle includes a horizontally arranged upper end and a lower end, and the upper and lower ends are connected by a vertical plate on their sides that are close to each other.
[0009] In a preferred embodiment, the upper and lower ends of the C-shaped buckle are provided with protrusions on their respective sides, and the two protrusions are tightly fitted to the connecting cylinder and the lens, respectively.
[0010] The beneficial effects of this utility model are as follows:
[0011] This invention significantly increases the contact area between the C-shaped buckle and the lens surface by setting a C-shaped buckle with a protrusion, thereby effectively dispersing the local stress at the pressing point and greatly reducing the probability of lens damage.
[0012] Furthermore, the C-shaped clips are installed from the top of the back cover using screws. Therefore, when replacing the lens, workers can use tools such as ladders to complete the operation from above the light fixture in a more convenient manner, thus effectively reducing the difficulty of replacement.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0019] Example 1
[0020] Refer to the instruction manual appendix Figures 1 to 4This embodiment proposes a C-shaped buckle reverse-pressure fixing structure for floodlight lens glass to solve the problem in the prior art where LED floodlights using screws to fix the lens glass are prone to stress concentration in local glass areas. After long-term use, micro-cracks are easily generated on the glass, which can lead to glass damage. At the same time, since screws are generally installed on the back cover from the bottom of the lens glass, when workers replace the lens glass of the light fixture installed at a high position, they need to operate from below the light fixture with an upward and outstretched posture, which makes the replacement difficult.
[0021] Includes: floodlight body 1, floodlight body 1 includes a back cover 11, the top of the back cover 11 is provided with a plurality of connecting tubes 12, and the bottom of the back cover 11 is provided with a lens 13;
[0022] It should be noted that the connecting cylinder 12 can be a threaded hole, and the edge contour of the lens 13 is adapted to the mounting area of ββthe back cover 11, making it easy to position the lens 13 during installation.
[0023] The back cover 11 is provided with a fixing mechanism 2, which includes several C-shaped buckles 21. The top of the C-shaped buckles 21 is provided with a through hole 22, which is adapted to the connecting tube 12.
[0024] It should be noted that several connecting cylinders 12 are evenly distributed on the top edge of the back cover 11. The size of the C-shaped buckle 21 can be adjusted according to the actual size and specifications of the lamp. When in use, the C-shaped buckle 21 presses the lens 13 by generating a certain elastic deformation. The C-shaped buckle 21 can be made of plastic.
[0025] In this embodiment, the specific implementation scenario is as follows: When installing the lens 13, firstly, the lens 13 is placed in a preset position on the back cover 11, then several C-shaped buckles 21 are aligned with the corresponding connecting cylinders 12 respectively, and are snapped onto the back cover 11 from the side, so that the two protrusions of the C-shaped buckles 21 are tightly fitted with the top of the connecting cylinder 12 and the bottom of the lens 13 respectively. Then, by using screws to pass through the through holes 22 and threaded into the connecting cylinder 12, the installation of the lens 13 can be completed.
[0026] It should be noted that, since the contact area between the boss and the lens 13 is significantly larger than that of the nut, the local stress at the clamping point can be effectively dispersed, thus greatly reducing the probability of damage to the lens 13.
[0027] Furthermore, since the screws are installed from the top of the back cover 11, when replacing the lens 13, the staff can use tools such as ladders to complete the operation from above the lamp in a more convenient posture, thus effectively reducing the difficulty of replacement.
[0028] The C-type buckle 21 includes a horizontally positioned upper end and a lower end, with the upper and lower ends connected by a vertical plate on their adjacent sides.
[0029] It should be noted that the dimensions of the vertical panels can be adjusted according to the actual situation.
[0030] The upper and lower ends of the C-shaped buckle 21 are provided with protrusions on their respective sides, and the two protrusions are tightly fitted to the connecting cylinder 12 and the lens 13, respectively.
[0031] It should be noted that the surface of the boss is set to a rough surface.
[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
