Description

Technical Field

[0001] The utility model relates to the technical field of grille screens, and in particular to an LED grille screen component. Background Art

[0002] LED screens are usually used in indoor applications such as shopping malls, exhibition halls, and conference rooms. Higher resolution and smaller pitch are usually required to ensure that viewers can get a good visual experience even at a closer distance. For outdoor billboards, building exterior walls and other applications, larger pitch may be more suitable for long-distance viewing and can improve transparency and wind resistance. In actual production, processing manufacturers produce LED screens of the same specifications at a time and deliver them to sellers. However, buyers have diverse needs, and sellers are required to adjust the LED screens according to their needs. Usually, the adjustments are to the spacing and number of light strips.

[0003] Existing LED grille screen assemblies usually include a frame and multiple grid plates. The light strips are arranged vertically to the grid plates and fixedly connected by multiple screws. Therefore, to remove the light strips or adjust the spacing between multiple light strips, multiple screws need to be screwed, which is cumbersome and affects processing efficiency. Therefore, we propose an LED grille screen assembly to solve this problem. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] References to "one embodiment" or "some embodiments" in this specification mean that one or more embodiments of the present invention include a particular feature, structure, or characteristic described in conjunction with that embodiment. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0026] Reference Figure 1-5The present application proposes an LED grille screen assembly, comprising a grille frame 1 and a plurality of light strips 2. A plurality of grille plates 3 are fixedly installed between the left and right inner walls of the grille frame 1 by bolts. A track groove is provided on the top of the grille plate 3, and a plurality of sliders 4 are slidably installed in the track groove. A clamping sleeve 5 is fixedly installed on the top of the slider 4. A connecting hole 6 is provided on the bottom inner wall of the track groove. A slide plate is fixedly installed on the bottom of the slider 4. The bottom of the slide plate passes through the connecting hole 6 and is fixedly installed with a positioning frame 7. A card plate 8 is vertically slidably installed in the positioning frame 7. A plurality of card slots 18 are provided on the bottom inner wall of the grille plate 3. The card plate 8 is adapted to the card slot 18, and the light strip 2 is movably clamped in the corresponding plurality of clamping sleeves 5.

[0027] The grid plate 3 is fixed in the grid frame 1 by bolts. This design allows the grid plate to be easily disassembled and replaced, which is beneficial for maintenance and upgrading.

[0028] The slider 4 slides in the track groove, so that the clamping sleeve 5 can move horizontally, thereby allowing the position of the light bar 2 on the grid plate 3 to be flexibly adjusted.

[0029] In some embodiments, as Figure 2 and Figure 3 As shown, a same flat plate 9 is slidably installed between the left and right inner walls of the positioning frame 7, the bottom of the card plate 8 is fixedly installed and connected to the top of the corresponding flat plate 9, and a plurality of supporting elastic members 10 are fixedly installed between the flat plate 9 and the bottom inner wall of the corresponding positioning frame 7.

[0030] The flat plate 9 is supported by multiple supporting elastic members 10 to achieve stable connection between the card plate 8 and the card slot 18. The multiple supporting elastic members 10 are arranged in the positioning frame 7 to prevent erosion by the external environment and to prevent the card plate 8 and the card slot 18 from separating from each other due to failure of a single elastic member.

[0031] A hook plate 11 is vertically slidably installed on the bottom inner wall of the positioning frame 7. The top of the hook plate 11 is fixedly connected to the bottom of the corresponding flat plate 9. One side of the hook plate 11 abuts against the bottom of the corresponding positioning frame 7 and forms a through hole 12. The setting of the hook plate 11 and the through hole 12 makes it convenient for the user to simultaneously release the fixation of multiple sliders 4 and the clamping sleeves 5, thereby improving the convenience of moving the light strip 2.

[0032] In some embodiments, as Figure 2 As shown, both sides of the clamping sleeve 5 are provided with a connected plane section, a vertical section, an arc section 13, a clamping section and a bevel section 14, a weakened groove is formed between the plane section, the vertical section and the arc section 13, and the plane section, the vertical section, the arc section 13, the clamping section and the bevel section 14 are connected in sequence from bottom to top.

[0033] This is to illustrate that it is divided into multiple sections, but it is actually produced in one piece. The arrangement of the planar section, vertical section and arc section 13 of the clamping sleeve 5 makes the clamping section have an inward clamping force, and the inclined section 14 facilitates the light strip 2 to slide into the clamping sleeve 5 from above. The clamping of the light strip 2 by the clamping sleeve 5 eliminates the need for multiple screws 17 connected to the grid, thereby facilitating the disassembly of the light strip 2.

[0034] In some embodiments, as Figure 5 As shown, the light bar 2 includes a PCB board and multiple SMD lamp beads, and the multiple SMD lamp beads are fixedly installed on the top of the corresponding PCB at equal intervals. A fixing sleeve is fixedly installed on the bottom of the PCB board, and the same power supply circuit 15 is fixedly installed in the multiple fixing sleeves.

[0035] The light bar 2 integrates the PCB board, SMD lamp beads and power supply circuit 15 to form a compact and fully functional component, which reduces the complexity of the assembly process and improves the reliability and stability of the entire LED grille screen.

[0036] In some embodiments, as Figure 5 As shown, multiple threaded holes 16 are provided on the front and back sides of the top of the grid frame 1, and threaded grooves are provided on the front and back sides of the bottom of the PCB board. The same screw 17 is installed in the threaded groove and the corresponding threaded hole 16. The light bar 2 only needs to be connected to the grid frame 1 through the screw 17.

[0037] Specifically, by removing the two screws 17 connecting the light bar 2 and the grid frame 1, and then inserting the long round rod into the multiple through holes 12 on the same straight line, the multiple hook plates 11 are driven to move downward synchronously, so that the card plate 8 is separated from the card slot 18, and the fixation of the multiple clamping sleeves 5 is released. By moving the light bar 2, the multiple clamping sleeves 5 are driven to move horizontally synchronously, and the spacing of the multiple light bars 2 is adjusted. By releasing the hook plate 11, the supporting elastic member 10 drives the flat plate 9 to move upward so that it is stuck in the designated card slot 18. The spacing of the light bars 2 is the product of the number of card slots 18 between the two light bars 2 on the same grid plate 3 and the spacing between the card slots 18.

[0038] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the present invention to the specific embodiments described. Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
