Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to an LED linear light with an easy-to-replace lampshade. Background Technology

[0002] LED linear lights are widely used in office buildings, shopping malls, and home decoration lighting scenarios due to their simple design, uniform light effect, and adaptability to various architectural and decorative styles. Traditional LED linear lights typically consist of a mounting base, a light source assembly, and a light-transmitting lampshade covering the light source. To ensure the integrity of the fixture and dustproof effect, the lampshade and the lamp body are usually fixed by an interference fit with a slot, or by end caps at both ends for limiting and sealing.

[0003] However, in actual use and maintenance, this traditional connection structure reveals significant limitations. The main problem is that when the lampshade yellows, ages, or breaks due to long-term use and needs replacement, or when it needs to be opened for cleaning and maintenance of the internal light source, the tight interference fit makes disassembly extremely difficult. Users often cannot remove the lampshade by hand and usually need to use tools such as screwdrivers to pry it off. This process is not only time-consuming and laborious but also easily causes scratches and deformation of the aluminum body of the lamp or breakage of the lampshade. Furthermore, with existing installation methods, the entire lamp is usually directly fixed to the wall with screws. If the end cap restricts the disassembly of the lampshade, users may even need to remove the entire lamp to replace the lampshade, resulting in high maintenance costs and low efficiency. Existing technical structures struggle to ensure both a stable connection and the ease of independent lampshade disassembly.

[0004] Therefore, this utility model proposes an LED linear light with an easy-to-replace lampshade to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an LED linear light with an easy-to-replace lampshade, aiming to improve the problems of cumbersome and inefficient operation during the installation and fixing of existing LED linear lights, as well as the high maintenance costs caused by the need to disassemble the entire light and the inability to quickly and independently remove the lampshade when maintaining, cleaning or replacing the lampshade.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an LED linear light with an easy-to-replace lampshade, comprising: a mounting plate, a light strip disposed at the bottom of the mounting plate, and a lamp cover disposed at the bottom of the light strip; and a locking assembly disposed between the mounting plate and the light strip, and a snap-fit ​​assembly disposed between the light strip and the lamp cover.

[0007] The locking assembly has a precise multi-link linkage structure, which includes a slotted plate fixedly connected to the bottom of the mounting plate, a clamping plate rotatably connected to the inside of the slotted plate, a support plate slidably connected to the inside of the slotted plate, and a locking block fixedly connected to the top of the light strip; a spring is also provided inside the slotted plate, one end of the spring abutting against the inner wall of the slotted plate, and the other end of the spring abutting against the support plate.

[0008] Furthermore, the support plate, the spring, and the clamping plate are combined through elastic transmission. Under the elastic force of the spring, the support plate presses against the clamping plate to keep it clamping the locking block. The buckle assembly includes a locking plate fixedly connected to the side wall of the lamp cover, a handle slidably connected inside the locking plate, and a locking post fixedly connected to the side wall of the lamp strip. The handle slides along the locking plate and engages or disengages with the locking post. A limiting post is also provided between the handle and the locking plate to limit the sliding stroke of the handle.

[0009] Preferably, the bottom surface of the slotted plate is provided with a rotating slot for the clamping plate to extend out, the middle part of the clamping plate is rotatably installed in the slotted plate via a rotating shaft, and one end of the clamping plate located inside the slotted plate slides against the side wall of the support plate.

[0010] Preferably, the top two sides of the card block are provided with guide slopes, and one end of the clamping plate extending outside the slot plate is provided with a hook structure that cooperates with the card block. When the light strip is pushed upward, the guide slope of the card block pushes the clamping plate to rotate against the resistance of the spring.

[0011] Preferably, the card plate has a groove on the side facing the light strip, the handle is slidably embedded in the groove, the surface of the handle has a strip-shaped limiting hole, and the limiting post is fixedly connected to the inner wall of the card plate and passes through the strip-shaped limiting hole.

[0012] Preferably, the handle has an L-shaped locking groove or a buckle groove at one end near the locking post, and the outer diameter of the locking post is adapted to the inner diameter of the L-shaped locking groove or buckle groove.

[0013] Preferably, the end of the handle away from the locking post extends out of the outside of the lamp cover and forms a toggle part. The surface of the toggle part is provided with anti-slip texture to facilitate operation by the user's fingers.

[0014] Preferably, the locking assembly is provided in several groups at intervals along the length of the mounting plate, and each group of the locking assembly includes two symmetrically arranged clamping plates, and the locking block is clamped between the two clamping plates in a T-shaped or inverted trapezoidal structure.

[0015] Preferably, the buckle assembly is symmetrically arranged on the opposite side walls of the lamp cover, and the locking post is correspondingly arranged on the opposite side walls of the lamp strip to ensure that the lamp cover is subjected to balanced forces.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome installation process of LED linear lights in the prior art, which often requires the use of screws for alignment and fixation and has low installation efficiency, by setting a locking component between the mounting plate and the light strip and utilizing the internal mechanical linkage of the spring, support plate and clamping plate. It achieves the technical effect of automatically locking and fixing the light strip without the need for additional tools, simply by pushing it upward, which greatly shortens the construction time and reduces the installation difficulty.

[0017] 2. This utility model solves the problem in the prior art that the entire lamp needs to be disassembled when replacing a damaged lamp cover or cleaning the interior, which is complicated and has high maintenance costs. It achieves the technical effect of independently and quickly disassembling and replacing the lamp cover without disassembling the main body of the lamp strip, greatly facilitating daily maintenance and cleaning.

[0020] 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.

[0021] Reference Figures 1-5 The present invention provides an embodiment of an LED linear light with an easy-to-replace lampshade, comprising a mounting plate 1 as a fixed base, a light strip 3 disposed below the mounting plate 1 for emitting light, and a lamp cover 4 disposed below the light strip 3 for light transmission and protection. In order to achieve quick assembly between the light strip 3 and the mounting plate 1, a locking assembly 5 is provided between the mounting plate 1 and the light strip 3. In order to achieve independent disassembly and assembly between the lamp cover 4 and the light strip 3, a snap-fit ​​assembly 2 is provided between the light strip 3 and the lamp cover 4.

[0022] Mounting plate 1 mainly serves as the mounting base for the entire device. Its top surface is attached to the surface of the mounting medium, such as a wall or ceiling. Mounting plate 1 has several mounting holes. Mounting plate 1 is securely fixed to the wall or ceiling by bolts passing through the mounting holes. The bottom surface of mounting plate 1 is fixedly connected to the slotted plate 501 of the locking assembly 5. The slotted plate 501 serves as the main support of the locking assembly 5. It has a storage cavity with a receiving space inside. The bottom surface of the slotted plate 501 has a rotating slot that connects the storage cavity to the external environment. A clamping plate 505 is rotatably connected inside the slotted plate 501. The middle part of the clamping plate 505 is rotatably installed in the storage cavity through a rotating shaft. The bottom of the clamping plate 505 extends out of the slotted plate 501 through the rotating slot. The clamping plate 505 serves as the main locking actuator and is used to grip and fix the light strip 3.

[0023] Meanwhile, a locking block 504 that cooperates with the clamping plate 505 is fixedly connected to the top of the light strip 3. The locking block 504 has a T-shaped or inverted trapezoidal structure. The locking block 504 can be inserted between two symmetrically arranged clamping plates 505 and clamped by the clamping plates 505. In order to ensure that the clamping plates 505 always maintain the tendency to clamp the locking block 504, a support plate 503 is also slidably connected inside the slot plate 501. The support plate 503 is located above or to the side of the clamping plate 505. One side wall of the support plate 503 and the clamping plate 505 are located in the slot plate 501. One end of the inner part slides and abuts against the support plate 503. The side of the support plate 503 away from the clamping plate 505 abuts against the spring 502. The spring 502 is in a compressed state and applies a continuous pushing force to the support plate 503. The end of the spring 502 away from the support plate 503 is stably abutted against the inner wall of the slot plate 501. Through the mechanical transmission between the spring 502, the support plate 503 and the clamping plate 505, the support plate 503 presses against the upper end of the clamping plate 505, forcing the lower end of the clamping plate 505 to retract inward, thereby forming a locking state for the locking block 504.

[0024] Regarding the connection between the lamp cover 4 and the light strip 3, the buckle assembly 2 includes a latching plate 202 fixedly connected to the outer wall of the lamp cover 4. The latching plate 202 has a U-shaped groove structure or a C-shaped guide rail shape. The open end of the latching plate 202 faces the inner side of the lamp cover 4 or the direction of the light strip 3. A sliding groove is provided on the side of the latching plate 202 facing the light strip 3. A handle 203 is slidably connected inside the latching plate 202. The handle 203 is slidably embedded in the sliding groove and can move back and forth along the length of the latching plate 202. Cooperating with it is a latching post 204 fixedly connected to the side wall of the light strip 3. The handle 203 is close to the latching post. One end of the handle 204 is provided with an L-shaped locking groove or buckle groove that matches the outer diameter of the locking post 204. By sliding the handle 203, the L-shaped locking groove can be engaged or disengaged from the locking post 204, thereby locking and releasing the lamp cover 4. In addition, in order to prevent the handle 203 from slipping, a limiting post 201 is provided between the handle 203 and the locking plate 202. The surface of the handle 203 is provided with an elongated limiting hole. The limiting post 201 passes through the elongated limiting hole and is fixedly connected to the inner wall of the locking plate 202. The limiting post 201 slides relative to each other in the elongated limiting hole, thereby limiting the maximum sliding stroke of the handle 203. The core carrier of the locking assembly 5, the slotted plate 501, has a cavity slide for the movement of each moving part. The bottom opening of the slotted plate 501 has a through hole for the lower end of the clamping plate 505 to pass through. The clamping plate 505 is rotatably connected to the inside of the slotted plate 501 via a rotating shaft. The bottom end of the clamping plate 505 located outside the slotted plate 501 is designed with an inwardly curved barb-like structure or a toothed structure. The barb-like structure is used to hook the bottom edge of the locking block 504 in the locked state to provide vertical suspension tension. At the same time, in order to provide continuous and stable locking force to the clamping plate 505 and realize the automatic reset function, the support plate 503 is slidably installed in the preset slide inside the slotted plate 501. The support plate 503 is located above or to the side of the clamping plate 505 and maintains a tight abutment with the upper side wall of the clamping plate 505 inside the cavity slide. The rotation angle of the clamping plate 505 is controlled by the linear displacement of the support plate 503.

[0025] Spring 502 is horizontally or vertically arranged in the receiving groove inside the slot plate 501. One end of spring 502 is fixedly abutted against the blind end of the inner wall of slot plate 501, and the other end of spring 502 directly presses against the side of support plate 503 away from clamping plate 505. Thus, a continuous mechanical transmission chain is formed inside slot plate 501, in which spring 502 pushes support plate 503, and support plate 503 then presses against clamping plate 505. This mechanical transmission chain forces clamping plate 505 to always have a tendency to rotate inward around the rotation axis and be in a closed clamping state. Corresponding to this locking structure is a locking block 504 fixedly arranged on the top of light strip 3. The locking block 504 is T-shaped or inverted trapezoidal in shape. Both sides of the top of locking block 504 are finely machined with guide bevels or rounded corners.

[0026] In the assembled state, the locking block 504 is inserted between two symmetrically arranged clamping plates 505. The guide slope at the top of the locking block 504 and the barbed structure at the bottom of the clamping plate 505 form a sliding fit. This locking structure, which uses the energy storage and reset of the spring 502 and the guide slope, ensures that when the light strip 3 is pushed upward for installation, the guide slope of the locking block 504 can convert the vertical upward pushing force into a horizontal component force that forces the clamping plate 505 to overcome the resistance of the spring 502 and rotate outward. When the locking block 504 is fully pushed into place, the spring 502 releases elastic potential energy to push the support plate 503 to reset, thereby causing the clamping plate 505 to rotate and lock the locking block 504. This achieves the technical effect of quickly installing the light strip 3 without the need for additional tools. At the same time, the multi-point clamping ensures the high stability and anti-vibration and anti-fall capability of the light strip 3 in the suspended state. Based on the above embodiments, this utility model also includes preferred technical details for the buckle assembly 2 and the locking assembly 5. In order to further improve the stability of the lamp cover 4 disassembly and assembly process and prevent the parts from falling off due to misoperation, the clamping plate 202 is designed as a U-shaped groove structure or a dovetail groove structure with the opening facing the inside of the lamp cover 4. The handle 203 is slidably embedded in the groove of the clamping plate 202 and forms a tight linear guide fit with the inner wall of the clamping plate 202. In order to limit the sliding stroke of the handle 203 and prevent the handle 203 from accidentally slipping out of the clamping plate 202, a long strip-shaped limiting hole extending along the sliding direction is opened in the middle of the handle 203. The limiting post 201 is fixedly connected to the inner bottom wall of the clamping plate 202 and passes vertically through the long strip-shaped limiting hole. The diameter of the limiting post 201 is smaller than the width of the long strip-shaped limiting hole and the top of the limiting post 201 is provided with an anti-detachment cap. The handle 203 can only slide back and forth relative to the clamping plate 202 within the length range of the long strip-shaped limiting hole.

[0027] Regarding the locking mechanism between the handle 203 and the locking post 204, an L-shaped locking groove or a semi-circular buckle notch is provided at the end of the handle 203 near the locking post 204. The outer diameter of the locking post 204 is matched with the inner diameter of the L-shaped locking groove or the semi-circular buckle notch. When the handle 203 slides inward, the L-shaped locking groove or the semi-circular buckle notch can cover and lock the outer cylindrical surface of the locking post 204, thereby achieving vertical locking. The end of the handle 203 away from the locking post 204 extends out of the outer contour of the lamp cover 4 and forms a toggle part for finger to operate. The surface of the toggle part is provided with several anti-slip textures or raised friction ridges to facilitate the application of force.

[0028] To ensure the stress balance and overall flatness of the light strip 3 and the light cover 4 during long-distance installation, the locking assembly 5 is arranged in several sets at intervals along the length of the mounting plate 1. Each set of locking assembly 5 includes two clamping plates 505 symmetrically arranged about the central axis of the light strip 3. The locking block 504 is firmly clamped between the two symmetrical clamping plates 505. Correspondingly, the locking assembly 2 is also symmetrically arranged on the opposite side walls of the light cover 4, and the locking post 204 is correspondingly arranged on the opposite side walls of the light strip 3. The double-sided symmetrical locking method ensures that the light cover 4 is firmly connected and will not tilt. In addition, to adapt to the fixing requirements of different installation environments, the surface of the mounting plate 1 is evenly provided with several waist-shaped mounting holes or round countersunk holes along the center line. The mounting bolts pass through the waist-shaped mounting holes or round countersunk holes to tightly fit and fix the mounting plate 1 to the wall or ceiling surface.

[0029] Working principle: When installing LED strip lights with easy-to-replace lamp covers, first fix the mounting plate 1 to the designated ceiling or wall position with bolts. Then, hold the light strip 3 with the lamp cover 4 attached and push it upwards to the locking assembly 5 at the bottom of the mounting plate 1. As the light strip 3 moves upwards, the locking block 504 at the top of the light strip 3 first contacts the barb part at the bottom of the clamping plate 505.

[0030] As the thrust is continuously applied, the guide ramp at the top of the clamping block 504 applies a lateral component force to the clamping plate 505, forcing the clamping plate 505 to rotate around the axis inside the slot plate 501. During the rotation of the clamping plate 505, one end of the clamping plate 505 located inside the slot plate 501 pushes the support plate 503 on the side wall to move horizontally. The movement of the support plate 503 then compresses the spring 502 at the top, causing the spring 502 to undergo elastic deformation and accumulate elastic potential energy. When the widest part of the clamping block 504 completely passes the barb of the clamping plate 505, the spring 502 releases its elastic potential energy to push the support plate 503 to reset. The support plate 503 pushes the clamping plate 505 in the opposite direction to make it rotate back to reset. The barb at the bottom of the clamping plate 505 tightly clamps the bottom edge of the clamping block 504, thereby firmly suspending the light strip 3 below the mounting plate 1, achieving the effect of quickly installing the light strip 3.

[0031] When it is necessary to replace the damaged lamp cover 4 or to clean and maintain the lamp cover 4, it is not necessary to disassemble the entire light strip 3. Simply operate the buckle assembly 2. First, hold the toggle part on the outside of the handle 203 on the side wall of the lamp cover 4 with your finger and apply a pulling force. After the handle 203 is subjected to force, it slides horizontally along the sliding groove inside the plate 202. During the movement of the handle 203, the limiting post 201 on the inner wall of the plate 202 slides relative to the handle 203 in the elongated limiting hole, which serves to guide and prevent the handle 203 from falling off.

[0032] As the handle 203 continues to slide, the L-shaped locking groove or buckle groove at the end of the handle 203 gradually disengages from the locking post 204 on the side wall of the light strip 3. When the handle 203 is completely freed from the restraint of the locking post 204, the lamp cover 4 is unlocked and separated from the light strip 3. At this time, the lamp cover 4 can be easily removed for subsequent operations. When installing a new lamp cover 4, simply push the handle 203 in the opposite direction to make it lock the locking post 204 again. The whole process is simple to operate and greatly reduces the difficulty of maintenance.
