Description

Technical Field

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

[0002] LED light strips refer to LEDs assembled on a strip-shaped FPC (flexible printed circuit board) or PCB rigid board, named for their strip-like shape.

[0003] A search revealed a Chinese patent document disclosing an easy-to-install LED light strip structure [Announcement No.: CN218883714U]. This structure includes a light strip body, a protective mechanism, and a safeguard mechanism. LED light bodies and capacitors are embedded in the surface of the light strip body. The surface of the light strip body is coated with a waterproof layer, and fixing blocks are welded to both the top and bottom ends of the light strip body. A fixing rod is fixedly connected to the inner wall of each fixing block. Connectors are installed at both ends of the outer wall of the light strip body. The safeguard mechanism is installed at the top of the light strip body. This easy-to-install LED light strip structure, through its protective mechanism and safeguard mechanism, facilitates installation. The protective sleeve in the protective mechanism protects the steel pins on the connectors from compression and deformation, preventing them from becoming unusable. Furthermore, the protective cover in the safeguard mechanism prevents the LED light bodies or capacitors on the light strip body from falling off due to external impacts or scratches during use.

[0004] Most existing LED light strips are fixed to PCB rigid boards with screws. During the installation process, tools such as screwdrivers are required, making it difficult for users to install without tools, thus reducing the practicality of LED light strips. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-install LED light strip structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install LED light strip structure, comprising a light strip body and a PCB rigid board, wherein the light strip body is located on the top of the PCB rigid board, and housings are fixedly connected to both sides of the light strip body, a snap-fit ​​groove is provided on one side of the housing, a snap-fit ​​block is provided inside the snap-fit ​​groove, the bottom of the snap-fit ​​block is fixedly connected to the top of the PCB rigid board, a positioning hole is provided on one side of the snap-fit ​​block, and a positioning mechanism is provided inside the housing;

[0007] The positioning mechanism includes a movable block movably disposed inside the housing. A positioning block is fixedly connected to one side of the movable block. One side of the positioning block penetrates the housing and extends into the interior of the positioning hole. Tension springs are provided on both sides of the movable block. One end of the tension spring is fixedly connected to the inner wall of the housing, and the other end of the tension spring is fixedly connected to one side of the movable block.

[0008] The disassembly mechanism is fixedly mounted on the positioning mechanism. When the light strip body is damaged, the light strip body can be disassembled through the disassembly mechanism.

[0009] Preferably, the disassembly mechanism includes a linkage block fixedly connected to one side of the movable block, two transmission blocks fixedly connected to one side of the linkage block, a transmission groove is provided on the top of the transmission block, a transmission rod is provided inside the transmission groove, a pressing rod is fixedly connected to the top of the transmission rod, and the two pressing rods extend to the outside of the housing on opposite sides.

[0010] Preferably, it also includes a stabilizing mechanism, which is fixedly disposed on both sides of the light strip body;

[0011] The stabilizing mechanism includes several stabilizing blocks fixedly connected to both sides of the light strip body. The top of each stabilizing block has a stabilizing hole, and a stabilizing rod is installed inside the stabilizing hole. The bottom of the stabilizing rod is fixedly connected to the top of the PCB rigid board.

[0012] Preferably, a conical block is fixedly connected to the top of the stabilizing rod, and the conical block is made of rubber.

[0013] Preferably, sliding blocks are fixedly connected to both sides of the positioning block, and the inner wall of the housing is provided with sliding grooves that cooperate with the sliding blocks.

[0014] Preferably, the bottom of the positioning block is sloped.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a positioning mechanism, can move the housing downward by aligning the position of the snap-fit ​​block and the snap-fit ​​groove. The positioning block will move downward synchronously with the housing. When the sloping part of the positioning block contacts the surface of the snap-fit ​​block, the positioning block will retract into the housing due to the squeezing effect. When the housing moves down to the point where the positioning block is opposite to the positioning hole, the tension generated by the tension spring will drive the moving block and the positioning block to move towards the side closer to the snap-fit ​​block, so that the positioning block enters the positioning hole, thus fixing the housing and completing the installation of the light strip body, which facilitates the installation.

[0017] 2. This utility model, by setting up a disassembly mechanism, can simultaneously press and push two pressing rods towards the side closest to the housing. The pressing rods will drive the transmission rod to move. The surface of the transmission rod will squeeze the inclined part of the inner wall of the transmission groove, causing the transmission block and the linkage block to move away from the locking block. The linkage block will drive the moving block and the positioning block to move away from the locking block along the trajectory of the sliding groove, so that the positioning block leaves the positioning hole and releases the restriction on the housing. At this time, the light strip body can be removed and replaced by moving it upward.

[0018] 3. By setting a stabilizing mechanism, this utility model can drive the stabilizing block to move downwards while the light strip moves downwards. When the bottom of the light strip contacts the top of the PCB rigid board, the stabilizing rod will be located inside the stabilizing hole, which further improves the stability of the light strip body.

[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] Please see Figure 1 - Figure 6 As shown,

[0028] Example 1:

[0029] An easy-to-install LED light strip structure includes a light strip body 1 and a PCB rigid board 2. The light strip body 1 is located on the top of the PCB rigid board 2. Both sides of the light strip body 1 are fixedly connected to a housing 3. A snap-fit ​​groove 4 is opened on one side of the housing 3. A snap-fit ​​block 5 is provided inside the snap-fit ​​groove 4. The bottom of the snap-fit ​​block 5 is fixedly connected to the top of the PCB rigid board 2. A positioning hole 6 is opened on one side of the snap-fit ​​block 5. A positioning mechanism is provided inside the housing 3.

[0030] The positioning mechanism includes a movable block 7 movably disposed inside the housing 3. A positioning block 8 is fixedly connected to one side of the movable block 7. One side of the positioning block 8 penetrates the housing 3 and extends into the interior of the positioning hole 6. Tension springs 9 are provided on both sides of the movable block 7. One end of the tension spring 9 is fixedly connected to the inner wall of the housing 3, and the other end of the tension spring 9 is fixedly connected to one side of the movable block 7.

[0031] The disassembly mechanism is fixedly mounted on the positioning mechanism. When the light strip body 1 is damaged, the light strip body 1 can be disassembled through the disassembly mechanism.

[0032] In this embodiment, considering that LED light strips are mostly fixed to the PCB rigid board 2 with screws, installation requires the use of tools such as screwdrivers. This makes installation difficult without tools, reducing the practicality of the LED light strip. Therefore, by setting a positioning mechanism, the housing 3 can be moved downwards by aligning the positions of the snap-fit ​​block 5 and the snap-fit ​​slot 4. The positioning block 8 will move downwards synchronously with the housing 3. When the sloping part of the positioning block 8 contacts the surface of the snap-fit ​​block 5, it will retract into the housing 3 due to compression. When the housing 3 moves down until the positioning block 8 is aligned with the positioning hole 6, the tension generated by the tension spring 9 will drive the moving block 7 and the positioning block 8 to move closer to the snap-fit ​​block 5, allowing the positioning block 8 to enter the positioning hole 6, thus fixing the housing 3 and completing the installation of the light strip body 1, facilitating installation.

[0033] Both sides of the positioning block 8 are fixedly connected to sliding blocks 19, and the inner wall of the housing 3 is provided with sliding grooves 20 that cooperate with the sliding blocks 19.

[0034] In this embodiment, by setting a sliding block 19 and a sliding groove 20, when the slope portion of the positioning block 8 contacts the surface of the locking block 5, the positioning block 8 and the moving block 7 can only move along the trajectory of the sliding groove 20 under the restriction of the sliding block 19, which plays the role of restricting the movement trajectory.

[0035] The bottom of positioning block 8 is sloping.

[0036] In this embodiment, by setting the positioning block 8, the bottom of the positioning block 8 is set in a slope shape. When the slope part of the positioning block 8 comes into contact with the surface of the snap-fit ​​block 5, the positioning block 8 will retract into the interior of the housing 3 due to the squeezing effect, thus playing a transmission role.

[0037] Example 2:

[0038] Based on Embodiment 1, the positioning mechanism in this embodiment facilitates the installation of the light strip body 1. However, considering that the light strip body 1 may be damaged after long-term use and needs to be replaced, the disassembly mechanism in this application includes a linkage block 10 fixedly connected to one side of the moving block 7. Two transmission blocks 11 are fixedly connected to one side of the linkage block 10. A transmission groove 12 is opened on the top of the transmission block 11. A transmission rod 13 is provided inside the transmission groove 12. A pressing rod 14 is fixedly connected to the top of the transmission rod 13. The two pressing rods 14 extend to the outside of the housing 3 on the side that is far away from each other.

[0039] In this embodiment, by setting up a disassembly mechanism, two pressing rods 14 can be pushed simultaneously towards the side close to the housing 3. The pressing rods 14 will drive the transmission rod 13 to move. The surface of the transmission rod 13 will squeeze the inclined part of the inner wall of the transmission groove 12, causing the transmission block 11 and the linkage block 10 to move away from the locking block 5. The linkage block 10 will drive the moving block 7 and the positioning block 8 to move away from the locking block 5 along the trajectory of the sliding groove 20, so that the positioning block 8 leaves the inside of the positioning hole 6, releasing the restriction on the housing 3. At this time, the light strip body 1 can be removed and replaced by moving it upward.

[0040] Example 3:

[0041] Based on Embodiment 1, the positioning mechanism in this embodiment facilitates the installation of the light strip body 1, but it overlooks the fact that the light strip body 1 is relatively long. If the sides are not restricted, it will affect the stability of the light strip body 1 itself. This application also includes a stabilizing mechanism, which is fixedly installed on both sides of the light strip body 1.

[0042] The stabilizing mechanism includes several stabilizing blocks 15 fixedly connected to both sides of the light strip body 1. The top of the stabilizing block 15 is provided with a stabilizing hole 16, and a stabilizing rod 17 is provided inside the stabilizing hole 16. The bottom of the stabilizing rod 17 is fixedly connected to the top of the PCB rigid board 2.

[0043] In this embodiment, by setting a stabilizing mechanism, the stabilizing block 15 can be moved downwards while the light strip moves downwards. When the bottom of the light strip contacts the top of the PCB rigid board 2, the stabilizing rod 17 will be located inside the stabilizing hole 16, which further improves the stability of the light strip body 1.

[0044] Preferably, a conical block 18 is fixedly connected to the top of the stabilizing rod 17, and the conical block 18 is made of rubber.

[0045] In this embodiment, by setting a conical block 18, when the stabilizing block 15 moves downward, the stabilizing hole 16 will squeeze the conical block 18. Since the conical block 18 is made of rubber, it will deform under pressure and pass through the stabilizing hole 16, pressing on the upper surface of the stabilizing block 15, thus playing an auxiliary positioning role.

[0046] Working principle: The user moves the housing 3 downward by aligning the snap-fit ​​block 5 and snap-fit ​​slot 4. The positioning block 8 moves downward synchronously with the housing 3. When the sloping part of the positioning block 8 contacts the surface of the snap-fit ​​block 5, the positioning block 8 will retract into the housing 3 due to the squeezing effect. When the housing 3 moves down to the position where the positioning block 8 is opposite to the positioning hole 6, the tension generated by the tension spring 9 will drive the moving block 7 and the positioning block 8 to move towards the side closer to the snap-fit ​​block 5, so that the positioning block 8 enters the positioning hole 6, thus fixing the housing 3 and completing the installation of the light strip body 1, which facilitates the installation.

[0047] As the light strip moves downward, it also moves the stabilizing block 15 downward. When the bottom of the light strip contacts the top of the PCB rigid board 2, the stabilizing rod 17 will be located inside the stabilizing hole 16, further improving the stability of the light strip body 1.

[0048] When the light strip body 1 needs to be replaced, by simultaneously pressing and pushing the two pressing rods 14 towards the side close to the housing 3, the pressing rods 14 will drive the transmission rod 13 to move. The surface of the transmission rod 13 will squeeze the inclined part of the inner wall of the transmission groove 12, causing the transmission block 11 and the linkage block 10 to move away from the locking block 5. The linkage block 10 will drive the moving block 7 and the positioning block 8 to move away from the locking block 5 along the trajectory of the sliding groove 20, so that the positioning block 8 leaves the inside of the positioning hole 6, releasing the restriction on the housing 3. At this time, the light strip body 1 can be removed and replaced by moving it upward.
