Description

Technical Field

[0001] This utility model relates to the field of linear light technology, and in particular to a guide groove for preventing misalignment when splicing linear lights. Background Technology

[0002] Currently, linear lights are widely used in commercial spaces, building facades, and interior decoration due to their simple and continuous lighting effect. In actual engineering projects, especially when long-distance continuous lighting is required, the guide channel (or housing) of linear lights often needs to be spliced ​​together from end to end using multiple prefabricated units.

[0003] In existing linear light guide channel splicing technology, simple interlocking, bolting, or snap-fit ​​connections are commonly used. However, when splicing long distances, these simple connection methods are prone to slight lateral or longitudinal misalignment at the connection point between two shells due to manufacturing tolerances of individual shells and alignment difficulties on the construction site. This is commonly referred to as "uneven seams." Once such misalignment occurs, it not only disrupts the visual continuity and aesthetics of the linear light's illumination lines but also creates additional difficulties for subsequent light strip installation and debugging, ultimately affecting the quality and efficiency of the entire project. Furthermore, this simple connection structure is also unable to effectively resist lateral stresses generated during construction or use, resulting in insufficient reliability and structural strength at the splice.

[0004] Therefore, this utility model proposes a guide groove to prevent misalignment when splicing linear lights, in order to solve the problem of alignment deviation and misalignment that easily occurs when splicing linear light housings over long distances in the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a guide groove for preventing misalignment in linear light splicing, which aims to improve the problem that the simple docking method of some existing guide grooves for preventing misalignment in linear light splicing easily leads to slight lateral or longitudinal misalignment of the housing when splicing over long distances.

[0006] This utility model provides a guide groove for preventing misalignment when splicing linear lights, including: a housing, a positioning groove and a positioning block; and an adhesive plate as the core innovative component.

[0007] The shell is a long strip structure that is spliced ​​end to end along its length. A positioning block is provided on the outer wall of one end, and a positioning groove matching the shape of the positioning block is provided on the inner wall of the other end.

[0008] The positioning block has a rectangular cross-section or similar geometric shape, and the positioning groove has a rectangular groove structure that matches it.

[0009] Furthermore, the positioning block and the positioning groove are connected by a sliding fit to limit the lateral and longitudinal displacement of the two shells at the splicing point, achieving initial anti-misalignment fixation. Based on this initial fixation, the outer surfaces of the mating ends of the two shells are fixedly connected by an adhesive plate. The adhesive plate is a long strip of material that spans across the outer surfaces of the two shells along their length, providing secondary reinforcement to the connection. This structural combination ensures the splicing accuracy of the linear light guide groove and the overall structural strength.

[0010] Preferably, the inner wall of the housing is provided with a limiting plate, which extends along the length of the housing and is used to provide lateral and longitudinal limiting support for the light strip installed in the guide groove of the linear light.

[0011] Preferably, the end of the limiting plate is provided with a lamp mounting hole, which is arranged in an array along the length of the limiting plate. The lamp mounting hole is used to engage the lamp beads of the linear light to achieve precise positioning of the lamp beads.

[0012] Preferably, there are two positioning blocks and two positioning slots. The two positioning blocks are symmetrically arranged on both sides of the outer wall of the housing, and the two positioning slots are symmetrically arranged on both sides of the inner wall of the housing, so as to improve the stability of positioning and the anti-torsion capability.

[0013] Preferably, the positioning block has a rectangular cross-sectional shape, the positioning groove has a rectangular cross-sectional shape that matches the cross-sectional shape of the positioning block, and the positioning block is inserted into the positioning groove in a sliding fit manner.

[0014] Preferably, the adhesive plate is a long strip of material with adhesive backing. The adhesive plate fixes the back of the connecting parts of the two shells together by adhesive backing to avoid affecting the light-emitting effect of the front of the shell.

[0015] Preferably, the shell has a U-shaped cross-section, and the positioning block and the positioning groove are both located on the sidewalls on both sides of the opening end of the U-shaped structure, which simplifies the manufacturing process of the shell.

[0016] Preferably, the limiting plates are symmetrically arranged on both sides of the inner wall of the housing, and the height and spacing of the limiting plates are matched with the width of the linear light strip to form a stable clamping of the light strip.

[0017] Preferably, the fit tolerance between the positioning block and the positioning groove is set to be less than or equal to 0.1 mm. This high-precision fit ensures the flatness of the splicing interface.

[0018] Preferably, the housing has bolt mounting holes at both ends for fixing the end caps with bolts, thereby achieving closure and protection of the terminal.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problem of horizontal or vertical misalignment that easily occurs when linear light housings are spliced ​​over long distances in the prior art by setting a positioning block on the outer wall and a positioning groove on the inner wall, thus achieving the technical effect of significantly improving splicing accuracy and initial alignment effect.

[0020] 2. This utility model solves the problem of insufficient strength and easy loosening of the existing technology by using an adhesive plate to fix the joint ends of the two shells. It achieves the technical effect of secondary reinforcement of the splicing connection and greatly improves the stability and reliability of the overall structure.

[0021] 3. This utility model solves the problem of easy shaking and twisting of the light strip after installation in the prior art by setting a limiting plate on the inner wall of the housing, and achieves the technical effect of limiting the main body of the linear light strip in the horizontal and vertical directions, which significantly improves the stability of the light strip after installation.

[0022] 4. This utility model solves the problems of inaccurate lamp bead positioning and low installation efficiency in the prior art by setting lamp mounting holes in an array at the end of the limiting plate, and achieves the technical effect of realizing precise lamp bead locking and positioning, greatly improving the installation convenience of the entire linear light system.

[0023] 5. This utility model solves the problem of obvious gaps caused by large splicing tolerances in the prior art by adopting a high-precision sliding fit between the positioning block and the positioning groove, thereby eliminating splicing gaps and ensuring that the guide groove of the linear light is straight and beautiful.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figures 1 to 3 This utility model provides a guide groove for preventing misalignment during the splicing of linear lights. It aims to solve the problems in the prior art where misalignment can easily occur between the outer shells of linear lights during long-distance splicing construction, leading to installation misalignment, and the structural connection stability is insufficient due to relying solely on butt joints.

[0028] like Figure 1 and Figure 2 As shown, the linear light splicing anti-misalignment guide groove mainly includes a housing 1 as an integral support carrier, and positioning and bonding components for connecting and reinforcing the ends of the housings 1. The housing 1 is a long strip structure spliced ​​end to end along the length direction. It is made of aluminum alloy or engineering plastic and has an overall U-shaped cross-section, which can provide space for the subsequent installation of linear light strips. When long-distance installation is required, multiple housings 1 are assembled into a continuous guide system through a specific end-to-end connection structure.

[0029] A positioning block 3 is integrally formed or fixedly provided on the outer wall of one end of the housing 1, while a positioning groove 2 matching the shape of the positioning block 3 is correspondingly provided on the inner wall of the other end of the housing 1. Preferably, there are two positioning blocks 3, which are symmetrically arranged on both sides of the outer wall of the housing 1. Correspondingly, there are also two positioning grooves 2, which are symmetrically arranged on both sides of the inner wall of the housing 1. When the two housings 1 are spliced ​​end to end, the positioning block 3 on the outer wall of the first housing 1 can be inserted into the positioning groove 2 on the inner wall of the second housing 1 in a sliding fit. The cross-sectional shape of the positioning block 3 is designed to be rectangular, and the cross-sectional shape of the positioning groove 2 is a rectangular groove that matches the cross-sectional shape of the positioning block 3. The fit tolerance between the positioning block 3 and the positioning groove 2 is set to be less than or equal to 0.1 mm. Through this high-precision socket fit, the relative displacement of the two housings 1 in the lateral and longitudinal directions at the splicing point can be restricted, thereby realizing the end-to-end connection of the two housings 1 and the initial anti-misalignment fixation, ensuring that the guide groove line is straight and the interface is flat after splicing.

[0030] An adhesive plate 5 is provided at the joint end where the two shells 1 are connected. The adhesive plate 5 is a long strip of adhesive material that spans the outer surface of the two shells 1 along the length of the shell 1. Specifically, the adhesive plate 5 is attached to the back or side of the joint of the two shells 1 by means of adhesive backing. The tension of the adhesive plate 5 is used to tightly pull the two shells 1 together, thereby providing secondary reinforcement to the connection of the two shells 1. This combination of internal and external connection method not only ensures the accuracy of installation, but also greatly improves the stability of the overall structure.

[0031] Reference Figure 1 and Figure 3 The limiting plates 4 are symmetrically arranged on both sides of the inner wall of the housing 1. The limiting plates 4 are integrally formed or welded to the inner wall of the housing 1 and extend along the length of the housing 1. The height and spacing of the limiting plates 4 are matched with the width of the linear light strip. The function of the limiting plates 4 is to provide precise lateral and longitudinal limiting support for the flexible or rigid light strip installed inside the housing 1, to prevent the light strip from shaking, twisting or falling off during installation or use, and to significantly improve the stability of the linear light strip after installation.

[0032] The end of the limiting plate 4 is provided with lamp mounting holes 6. The lamp mounting holes 6 are arranged in an array along the length of the limiting plate 4. The lamp mounting holes 6 are circular holes, and their size and spacing are adapted to the spacing and size of the lamp beads on the standard linear light FPC flexible light strip. In the assembled state, the lamp beads of the linear light strip are pushed into or pressed into the lamp mounting holes 6 of the limiting plate 4. This dual fixing structure consists of the clamping of the light strip body by the limiting plate 4 and the precise locking of the lamp beads by the lamp mounting holes 6.

[0033] The housing 1 has bolt mounting holes at both ends for installing end caps. The end caps are fixed to the bolt mounting holes by bolts, which serve to prevent dust and water and improve the appearance of the terminal. The specific internal structure is well known in the field and will not be described in detail here.

[0034] Reference Figure 1 The cross-section of the shell 1 is preferably a U-shaped structure. The U-shaped structure has a bottom wall and side walls extending vertically from both sides of the bottom wall. The positioning block 3 and the positioning groove 2 are both provided on the side walls on both sides of the opening end of the U-shaped structure. Reference Figure 1 and Figure 2The number of positioning blocks 3 is preferably two, and the number of positioning grooves 2 is also preferably two. The two positioning blocks 3 are symmetrically arranged on the two side walls of the outer wall of one end of the housing 1, and the two positioning grooves 2 are symmetrically arranged on the two side walls of the inner wall of the other end of the housing 1. The cross-sectional shape of the positioning blocks 3 is preferably rectangular, and the cross-sectional shape of the positioning grooves 2 is a rectangular groove that matches the cross-sectional shape of the positioning blocks 3. The positioning blocks 3 are inserted into the positioning grooves 2 by sliding fit. The fit tolerance between the positioning blocks 3 and the positioning grooves 2 is preferably set to be less than or equal to 0.1 mm. This high-precision fit effectively eliminates splicing gaps and misalignments. Reference Figure 2 The adhesive plate 5 is preferably a long strip of material. The adhesive plate 5 fixes the back of the connecting part of the two shells 1 by means of adhesive backing. The setting of the adhesive plate 5 does not affect the front appearance and luminous effect of the shell 1. Reference Figure 3 Limiting plates 4 are symmetrically arranged on both sides of the inner wall of housing 1. The height and spacing of the limiting plates 4 match the width of the linear light strip, forming a clamping effect on the light strip. Bolt mounting holes are provided at both ends of housing 1 for fixing the end caps with bolts.

[0035] The implementation principle of this application embodiment is as follows: When installing long-distance linear lights, according to the required construction distance, a corresponding number of housings 1 are placed and connected end to end. In specific operation, the positioning block 3 on the outer wall of the previous housing 1 is aligned and inserted into the positioning groove 2 on the inner wall of the next housing 1. The rectangular cross-section of the positioning block 3 and the positioning groove 2 are slidably engaged to limit the radial misalignment of the two housings 1 at the splicing point, thereby achieving the initial alignment and fixation of the two housings 1. After the initial splicing is completed, the adhesive plate 5 is covered and bonded to the back or side of the joint where the two shells 1 are connected. The physical connection force of the adhesive plate 5 is used to reinforce the connection position of the two shells 1 for a second time, which effectively prevents the shells 1 from axially separating or loosening after being subjected to force, and greatly improves the overall straightness and structural strength of the linear light guide groove. After the housing 1 is assembled and fixed, the linear light strip is embedded in the U-shaped groove inside the housing 1. The limiting plates 4 on both sides of the inner wall of the housing 1 clamp and limit the main body of the light strip to prevent the light strip from shaking. At the same time, the light beads on the light strip are correspondingly inserted into the light mounting holes 6 on the limiting plates 4.
