Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically to an LED light strip that is easy to connect. Background Technology

[0002] LED light strips are lighting fixtures that assemble light-emitting diodes (LEDs) onto a strip-shaped FPC (flexible printed circuit board) or PCB (rigid board), named for their strip-like shape. LED light strips typically consist of several unit groups and come in single-color and tri-color composite varieties, using an external 12V DC power supply. Their main characteristics include high intensity, high temperature resistance, excellent light color, energy saving, and environmental friendliness, with a lifespan generally ranging from 80,000 to 100,000 hours.

[0003] The patent with publication number CN218845815U discloses an LED light strip that is easy to connect. It includes a first lamp holder and a second lamp holder. Several surface-mount LEDs are fixedly bonded to the outer surfaces of the first lamp holder and the second lamp holder. A locking block is fixedly connected to one end of the second lamp holder. An open box is fixedly connected to the end of the first lamp holder near the second lamp holder. This device allows the first lamp holder and the second lamp holder to be quickly connected by pushing the locking block into the open box, so that the right-angled ends of the two right-angled triangular blocks engage with the corners of the two L-shaped blocks, which facilitates the rapid arrangement of the LED light strip.

[0004] However, this device has a drawback: since the opening box and the locking block are fixedly connected to the lamp holders, the angle between the first and second lamp holders cannot be adjusted after the locking block is inserted into the opening box. In real-world LED strip installation, the angle of the strip needs to be adjusted according to the terrain. The fixed angle of the opening box and locking block makes it difficult to ensure the installation of LED strips at various angles, thus greatly reducing its practicality. Therefore, an easy-to-connect LED strip is proposed to solve the problem that it is difficult to adjust the angle between the strips according to needs after the existing LED strips are connected. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an LED light strip that is easy to connect, thus solving the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an LED light strip that is easy to connect, comprising a flexible circuit board, a second flexible circuit board disposed on one side of the flexible circuit board, and fixing seats disposed on both opposite sides of the flexible circuit board and the second flexible circuit board. The fixing seats are connected to the flexible circuit board and the second flexible circuit board by a connecting mechanism. A U-shaped seat is fixedly connected to the right side of the left fixing seat. A rotating seat is rotatably disposed in the inner cavity of the U-shaped seat. A groove is formed on the top of the U-shaped seat. A limit bolt is disposed in the inner cavity of the groove. A limit nut is fixedly connected to the bottom inner wall of the rotating seat. Several LED beads are disposed on the top of both the flexible circuit board and the second flexible circuit board.

[0009] Preferably, the limiting bolt passes through the groove and the U-shaped seat, and the U-shaped seat and the limiting bolt are connected by threads.

[0010] Preferably, the limiting bolt passes through the rotating seat and the two are rotatably connected, and there is a small frictional force between the U-shaped seat and the rotating seat.

[0011] Preferably, the connecting mechanism includes a fastening plate disposed in the inner cavity of the fixing seat, the top of the fastening plate is provided with a fastening bolt, and the top of the fixing seat is provided with a second groove.

[0012] Preferably, the fastening bolt extends through the second groove and is threaded to the fixing seat, and the fastening bolt and the fastening plate are rotatably connected by a bearing.

[0013] Preferably, the inner wall of the fixed seat has symmetrically formed limiting grooves at both ends, and the inner cavity of the limiting groove is provided with a limiting slider, which is fixedly connected to the fastening plate.

[0014] (III) Beneficial Effects

[0015] 1. This easy-to-connect LED light strip allows for adjustment of the angle between connected LED light strips. The angle between the flexible circuit board and the second flexible circuit board can be adjusted using the limiting bolts. Then, a tool is used to rotate the nut on the limiting bolt located in the groove. This increases the pressure between the U-shaped seat and the rotating seat, fixing the adjusted light strip position. This solves the problem of difficulty in adjusting the angle between LED light strips after connection.

[0016] 2. This easy-to-connect LED light strip allows you to place one side of the flexible circuit board into the inner cavity of the fixing base. Then, using a tool, rotate the fastening bolt in the second groove to rotate it. With the help of the bearing, the fastening plate moves down to make contact with the flexible circuit board, thereby connecting the flexible circuit board to the fixing base. Even if the flexible circuit board needs to be cut or other sizes of light strips need to be connected, the fixing base can still be fixed on the cut or new size flexible circuit board, improving the practicality of this easy-to-connect LED light strip.

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.

[0024] Example: Please refer to Figure 1-5An easy-to-connect LED light strip includes a flexible circuit board 1, a second flexible circuit board 2 is provided on one side of the flexible circuit board 1, and fixing seats 3 are provided on both opposite sides of the flexible circuit board 1 and the second flexible circuit board 2. The fixing seats 3 are connected to the flexible circuit board 1 and the second flexible circuit board 2 by a connecting mechanism 4. A U-shaped seat 5 is fixedly connected to the right side of the left fixing seat 3. A rotating seat 6 is rotatably provided in the inner cavity of the U-shaped seat 5. A groove 7 is opened on the top of the U-shaped seat 5. A limit bolt 8 is provided in the inner cavity of the groove 7. A limit nut 9 is fixedly connected to the bottom inner wall of the rotating seat 6. Several LED beads 10 are provided on the top of both the flexible circuit board 1 and the second flexible circuit board 2.

[0025] Furthermore, the limiting bolt 8 passes through the groove 7 and the U-shaped seat 5, and the U-shaped seat 5 and the limiting bolt 8 are connected by threads.

[0026] Furthermore, the limiting bolt 8 passes through the rotating seat 6 and the two are rotatably connected. There is a small friction between the U-shaped seat 5 and the rotating seat 6. According to the angle requirements of the light strip installation, the angle between the flexible circuit board 1 and the second flexible circuit board 2 is adjusted under the action of the limiting bolt 8. Then, the nut on the limiting bolt 8 located in the groove 7 is rotated with the tool, and the pressure between the U-shaped seat 5 and the rotating seat 6 is increased in conjunction with the limiting bolt 9, so as to fix the position of the light strip with the adjusted angle.

[0027] Furthermore, the connecting mechanism 4 includes a fastening plate 401 disposed in the inner cavity of the fixed seat 3, a fastening bolt 403 disposed on the top of the fastening plate 401, and a second groove 402 provided on the top of the fixed seat 3.

[0028] Furthermore, the fastening bolt 403 penetrates into the second groove 402 and is threadedly connected to the fixing seat 3. The fastening bolt 403 and the fastening plate 401 are rotatably connected by the bearing 404. One side of the flexible circuit board 1 is placed into the inner cavity of the fixing seat 3, and then the fastening bolt 403 in the second groove 402 is rotated using a tool. With the cooperation of the bearing 404, the fastening plate 401 is moved down to press against the flexible circuit board 1, thereby connecting the flexible circuit board 1 to the fixing seat 3. Even if the flexible circuit board 1 needs to be cut or spliced ​​with other sizes of light strips, the fixing seat 3 can still be fixed on the cut or new size flexible circuit board 1, improving the practicality of this easy-to-splice LED light strip.

[0029] Furthermore, the inner cavity wall of the fixed base 3 is symmetrically provided with limiting grooves 405 at both ends, and the inner cavity of the limiting groove 405 is provided with limiting sliders 406. The limiting sliders 406 are fixedly connected to the fastening plate 401. The limiting sliders 406 in the limiting groove 405 improve the stability of the fastening plate 401 during the up and down movement, that is, improve the stability of the fixed base 3 after it is connected to the flexible circuit board 1 or the second flexible circuit board 2.

[0030] Working principle: When using this easy-to-connect LED light strip, the flexible circuit board 1 and the second flexible circuit board 2 are connected to the fixed base 3 using the connecting mechanism 4. The connection is achieved with the rotating base 6 in the U-shaped base 5. If a bend is required during the LED light strip installation, the angle between the flexible circuit board 1 and the second flexible circuit board 2 can be adjusted according to the angle requirements under the action of the limiting bolt 8. Then, the nut on the limiting bolt 8 located in the groove 7 is rotated with a tool, and the pressure between the U-shaped base 5 and the rotating base 6 is increased with the limiting bolt 9, thus fixing the position of the light strip with the adjusted angle. This solves the problem that it is difficult to adjust the angle between the light strips according to the requirements after the existing LED light strips are connected.
