Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a flexible and bendable LED light strip. Background Technology

[0002] LED light strips are lighting products that use special processing techniques to solder LED lights onto copper wires or flexible printed circuit boards (FPCs) and then connect them to a power source to emit light. Due to their advantages such as energy saving, high brightness, rich colors, and convenient installation, they are widely used in home decoration, advertising signage, automotive interiors, and many other fields.

[0003] Flexible and bendable LED light strips, as the name suggests, are LED light strips that can be bent into various shapes to meet different needs. In home decoration, people often use these light strips to decorate the edges of furniture and the corners of ceilings to create a unique atmosphere.

[0004] The existing flexible and bendable LED light strip has the following shortcomings:

[0005] On the one hand, existing LED light strips are mostly fixed using adhesive. However, flexible LED light strips are soft and require frames of various shapes for installation. Existing fixing methods make it difficult to easily fix flexible LED light strips to frames of different shapes, which is not only cumbersome but also results in poor fixing. On the other hand, existing LED light strips are limited in length, often requiring multiple strips to be spliced ​​together in actual use. However, existing splicing structures have poor splicing effects and are prone to loosening during use, which affects the stable light emission of the LED strips and reduces the user experience. Utility Model Content

[0006] This utility model proposes a flexible and bendable LED light strip. When installing the light strip, the lower pressure plate and the upper pressure plate are rotated to clamp the frame. The arc groove is adapted to the circular frame, and the rotating baffle is used for positioning to prevent loosening. When splicing, rotating the knob drives the bidirectional screw to operate. The multiple fixing mechanisms make the light strip spliced ​​tightly, improving the installation and splicing effect, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a flexible and bendable LED light strip, comprising two flexible outer shells, a flexible inner shell fixedly connected to the upper part of the inner shell, a flexible circuit board fixedly connected to the middle of the inner shell, a plurality of LED beads electrically connected to the top of the flexible circuit board, a plurality of connection holes opened at the bottom of the flexible outer shell, a fixing buckle provided at the lower part of the connection holes, and a splicing component provided at the opposite ends of the two flexible outer shells.

[0008] The fixing buckle includes a connecting plate, which is fixedly connected to the inner surface of the connecting hole. An upper pressure plate is fixedly connected to the bottom of the connecting plate. A support column is fixedly connected to the bottom right side of the upper pressure plate. A rotating lower pressure plate is rotatably connected to the outer side of the support column. An arc-shaped groove is opened in the middle of the opposite surface of the rotating lower pressure plate and the upper pressure plate. A rotating baffle is rotatably connected to the bottom end of the support column. The rotating baffle is disposed on the lower surface of the rotating lower pressure plate.

[0009] Preferably, the splicing assembly includes a splicing plate, and the splicing plate has insertion slots on both the left and right sides, and the flexible outer shell is slidably inserted into the inner surface of the insertion slots.

[0010] Preferably, a bidirectional screw is rotatably connected to the middle of the splicing plate, and the front and rear ends of the bidirectional screw pass through the front and rear sides of the outer surface of the splicing plate respectively and are fixedly connected to knobs.

[0011] Preferably, the outer surface of the bidirectional screw is threaded with threaded sliding plates on both the front and rear sides, and the outer surface of the threaded sliding plates is slidably sleeved with sliding sleeves on both the left and right sides.

[0012] Preferably, a pull rod is movably connected to the side of the sliding sleeve away from the insertion slot, and the end of the pull rod away from the sliding sleeve is movably connected to the inner wall of the splicing plate.

[0013] Preferably, two triangular retaining plates are fixedly connected to the side of the sliding sleeve near the insertion slot.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. In this utility model, when installing LED light strips, the LED light strips are placed on the frame, and the rotating lower pressure plate is rotated to cooperate with the upper pressure plate to clamp the shaped frame. The arc groove design allows the upper pressure plate and the rotating lower pressure plate to fit tightly against the circular frame, achieving stable clamping of the circular frame. After clamping, the rotating baffle is rotated to the lower surface of the rotating lower pressure plate to position the rotating lower pressure plate and prevent it from loosening. This structure does not require adhesive, is easy to operate, and can conveniently and firmly fix the LED light strips on frames of different shapes, greatly improving the convenience and fixing effect of LED light strip installation.

[0016] 2. In this utility model, rotating the knob drives the bidirectional screw to rotate. Utilizing the thread principle, the threaded slide plate drives the sliding sleeve plate to slide, thereby causing the triangular clamping plate to compress the flexible outer shell. At the same time, under the pulling action of the pull rod, the sliding sleeve plate can slide flexibly on the outer surface of the threaded slide plate. The sliding sleeve plate pulls the flexible outer shell plate into the insertion groove through the triangular clamping plate to shrink and press it tightly. This multi-fixing mechanism ensures that the LED light strips are tightly connected after splicing, effectively preventing loosening at the splicing point, and improving the splicing effect and user experience of the LED light strips.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: it includes two flexible outer shells 1, a flexible inner shell 11 is fixedly connected to the upper part of the inner shell 1, a flexible circuit board 12 is fixedly connected to the middle of the inner shell 11, a plurality of LED beads 13 are electrically connected to the top of the flexible circuit board 12, a plurality of connecting holes 14 are opened at the bottom of the flexible outer shell 1, a fixing buckle 15 is provided inside the lower part of the connecting holes 14, and a splicing component 2 is provided at the opposite ends of the two flexible outer shells 1, the fixing buckle 15 covers... The device includes a connecting plate 151, which is fixedly connected to the inner surface of the connecting hole 14. An upper pressure plate 152 is fixedly connected to the bottom of the connecting plate 151. A support column 153 is fixedly connected to the bottom right side of the upper pressure plate 152. A rotating lower pressure plate 154 is rotatably connected to the outer side of the support column 153. An arc-shaped groove 155 is provided in the middle of the opposite surface of the rotating lower pressure plate 154 and the upper pressure plate 152. A rotating baffle 156 is rotatably connected to the bottom end of the support column 153. The rotating baffle 156 is disposed on the lower surface of the rotating lower pressure plate 154.

[0025] The overall effect of Embodiment 1 is as follows: When installing LED light strips, users can easily place the LED light strips on the required fixed frame, and then rotate the rotating lower pressure plate 154 to cooperate with the upper pressure plate 152 to clamp and fix the frame. When the frame is circular, the arc groove 155 design allows the upper pressure plate 152 and the rotating lower pressure plate 154 to fit tightly against the circular frame, achieving stable clamping of the circular frame. After clamping, rotate the rotating baffle 156 to the lower surface of the rotating lower pressure plate 154 to position the rotating lower pressure plate 154 and prevent it from loosening. Thus, the LED light strips can be conveniently and firmly fixed on frames of different shapes, abandoning the traditional adhesive method and greatly improving the convenience and fixing effect of LED light strip installation.

[0026] Example 2: As Figure 4 As shown, this utility model provides a technical solution: the splicing component 2 includes a splicing plate 21, and the left and right sides of the splicing plate 21 are provided with insertion slots 22. The flexible outer shell 1 is slidably inserted into the inner surface of the insertion slots 22. The middle part of the splicing plate 21 is rotatably connected to a bidirectional screw 24. The front and rear ends of the bidirectional screw 24 pass through to the front and rear sides of the outer surface of the splicing plate 21 respectively and are fixedly connected to knobs 23. The front and rear sides of the outer surface of the bidirectional screw 24 are threadedly connected to threaded sliding plates 25. The left and right sides of the outer surface of the threaded sliding plates 25 are slidably sleeved with sliding sleeves 26. The side of the sliding sleeve 26 away from the insertion slots 22 is movably connected to a pull rod 27. The end of the pull rod 27 away from the sliding sleeve 26 is movably connected to the inner wall of the splicing plate 21. The side of the sliding sleeve 26 near the insertion slots 22 is fixedly connected to two triangular clamping plates 28.

[0027] The effect achieved by the entire embodiment 2 is as follows: When splicing LED light strips, the flexible outer shells 1 of the two LED light strips are respectively inserted into the insertion slots 22 on both sides of the splicing plate 21. Then, the knob 23 is turned, which drives the bidirectional screw 24 to rotate. The bidirectional screw 24 causes the threaded slide plate 25 to slide the sliding sleeve 26 through the thread action. The triangular retaining plate 28 on the sliding sleeve 26 squeezes the flexible outer shell 1. At the same time, under the pulling action of the pull rod 27, the sliding sleeve 26 can slide flexibly on the outer surface of the threaded slide plate 25. The sliding sleeve 26 pulls the flexible outer shell 1 into the insertion slot 22 through the triangular retaining plate 28 to shrink and press it tightly, effectively preventing loosening at the splicing point, realizing tight splicing of LED light strips, and significantly improving the splicing effect and user experience of LED light strips.

[0028] The working principle of the entire device is as follows: When it is necessary to install LED light strips, the fixing buckle 15 plays its role, placing the light strip on the frame. The rotating lower pressure plate 154 is rotated around the support column 153 as the axis, so that the rotating lower pressure plate 154 and the upper pressure plate 152 clamp the frame. If the frame is circular, the arc groove 155 can fit the outline of the frame and provide a stable clamping force. Then, the rotating baffle 156 is rotated around the support column 153 as the axis to the lower surface of the rotating lower pressure plate 154, restricting the rotation of the rotating lower pressure plate 154 and preventing it from loosening, thus fixing the LED light strip on the frame.

[0029] When LED light strips need to be spliced, the splicing assembly 2 starts to operate. First, the flexible outer shells 1 of the two LED light strips are aligned and inserted into the insertion slots 22 on both sides of the splicing plate 21. The knob 23 is turned, which drives the bidirectional screw 24 to rotate around its axis. Since the threads on the front and back sides of the bidirectional screw 24 rotate in opposite directions, the threaded slide plate 25 will move along the bidirectional screw 24 towards each other. During the movement of the threaded slide plate 25, the sliding sleeve 26 moves accordingly. The triangular clamping plate 28 installed on the sliding sleeve 26 begins to squeeze the flexible outer shell 1. At the same time, one end of the pull rod 27 is connected to the sliding sleeve 26, and the other end is connected to the inner wall of the splicing plate 21. The pull rod 27 will generate an additional pulling force on the sliding sleeve 26, causing the sliding sleeve 26 to further pull the flexible outer shell 1 into the insertion slot 22 through the triangular clamping plate 28, thereby realizing the tight splicing of the two LED light strips and meeting the user's requirements for the length of the LED light strip.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
