Description

Technical Field

[0001] The present invention belongs to the technical field of LED backlight strips, and specifically relates to an energy-saving and environment-friendly LED backlight strip. Background Art

[0002] According to the patent document with the authorization announcement number of "CN209415164U" and the invention name of "An energy-saving and environment-friendly LED backlight strip", it is recorded in the specification that: during use, through the fixing block arranged at the upper right end of the light strip board and the clamping part arranged at the lower right end of the light strip board, and through the clamping groove opened on the fixing block, the clamping part on one light strip board is clamped into the clamping groove on another light strip board, increasing the length of the light strip board. When clamping, move the push block to make the moving board move. At this time, under the action of the spring in the installation groove, the electrode connector pops out and is simultaneously connected to the electrode head interface, so that the two light strip boards can be used normally. Through the operation of the LED backlight source, due to long-term operation, the temperature around the heat dissipation chamber gradually rises. Through the heat absorption of the heat sink and then through the heat dissipation holes, the heat is transferred out of the heat dissipation chamber, so that the temperature around the heat dissipation chamber is reduced, thereby increasing the service life of the LED backlight source. However, there are still the following defects:

[0003] When connecting two light strip boards, they can only be connected and installed along the length direction of the light strip board.

On the side of the movable plate 402 away from the clamping rod 404, first springs 406 are symmetrically installed. One end of the first spring 406 is fixedly connected to the inner wall of the side of the movable groove 401 away from the circular rotating block 303. An end rod groove 407 is coaxially formed inside the limit rotating block 304 on the side close to the lamp body 2, and the end rod groove 407 penetrates to the side of the limit rotating block 304 away from the circular rotating block 303. The end rod groove 407 is communicated with one end of the movable groove 401. A pulling rotating rod 408 is movably installed inside the end rod groove 407. The outer wall of the pulling rotating rod 408 is fixedly connected to one end of the movable plate 402. On one side of the lamp strip body 1 close to the lamp body 2, two outer cylinders 413 are symmetrically installed. The outer cylinders 413 are coaxially arranged with the circular installation groove 301. A third rod groove 412 is coaxially formed at one end of the outer cylinder 413 close to the lamp strip body 1, and the third rod groove 412 penetrates into the interior of the limit circular groove 302. One end of the pulling rotating rod 408 passes through the third rod groove 412 and enters the interior of the outer cylinder 413. An activity circular plate 409 is installed at one end of the pulling rotating rod 408, and the activity circular plate 409 is movably installed inside the outer cylinder 413. The diameter of the activity circular plate 409 is larger than the diameter of the pulling rotating rod 408.

After the pull rod 411 moves back, the circular rotating block 303 can be repositioned and fixed, improving the connection stability and the installation efficiency.The power connection plug rod 307 needs to be inserted into the power connection slot 309 to complete the electrical connection of the second contact 308 and the third contact 310 of the light bar body 1. When the pull rod 411 moves back, it drives the movable plate 402 to move back, thereby driving the clamping rod 404 to move back. So when installing, the clamping rod 404 moves back and is clamped into the clamping groove 405 on the power connection plug rod 307, which is convenient for clamping and fixing the two light bar bodies 1 and improves the installation efficiency.

One end of the second connecting rod 521 penetrates to the end of the screw 518 close to the first moving block 503. One end of the second connecting rod 521 is fixedly connected to the first moving block 503. When the positioning groove 410 is clamped with the pull rod 411, the pull rod 411 cannot rotate.Rotate the screw rod 518 to move it towards the inside of the inner groove 502, thereby pushing the first moving block 503 to move. Push the push rod 507 towards the fixed cylinder 509 through the connecting rod 505, thereby pushing the movable block 510 to move, and then pushing the power connection plug rod 307 to move, which is convenient for adjusting the distance between the power connection plug rod 307 and the lamp strip body 1, so as to adjust the distance between the two lamp strip bodies 1 and facilitate installation.

[0038] Working principle: During operation, pull the pull rod 411 to move the pull rod 408 outwards, so that the positioning groove 410 on the movable circular plate 409 disengages from the positioning block 414 on the inner wall of the outer cylinder 413. Then rotate the pull rod 411. Since the first rod groove 403 on the pull rod 408 is located inside the movable groove 401, the circular rotating block 303 is driven to rotate, which is convenient for adjusting the orientation of the power connection plug rod 307 and the power connection slot 309 on the outside of the circular rotating block 303. Since the power connection plug rod 307 and the power connection slot 309 are perpendicularly arranged, the angle adjustment of the circular rotating block 303 is generally 90 degrees. After the angle adjustment is completed, release the pull rod 411, so that the pull rod 408 and the movable plate 402 move back under the elastic force of the first spring 406, and the positioning groove 410 engages with the positioning block 414, thereby positioning the angle of the circular rotating block 303. During the angle adjustment, the first conductive slide bar 306 on the outer wall of the circular rotating block 303 is always in contact with the first contact point 305;

[0039] However, when the two circular mounting grooves 301 need to be connected along the length direction, adjust the circular rotating block 303 at one end of the lamp strip body 1 so that the power connection plug rod 307 is parallel to the lamp strip body 1, and adjust the circular rotating block 303 at the other end so that the power connection slot 309 is parallel to the lamp strip body 1. Insert the power connection plug rod 307 at one end of one lamp strip body 1 into the power connection slot 309 at one end of the other lamp strip body 1 to complete the power connection. When the two lamp strip bodies 1 need to be connected along the width direction, adjust the circular rotating blocks 303 at both ends of one lamp strip body 1 so that the power connection plug rods 307 face downwards, and adjust the circular rotating blocks 303 at both ends of the other lamp strip body 1 so that the power connection slots 309 face upwards. Insert the downward-facing power connection plug rod 307 into the upward-facing power connection slot 309, which is convenient for connecting the two lamp strip bodies 1 and does not require wire connection, facilitating use;

[0040] When the power connection plug rod 307 is inserted into the power connection slot 309, pull the pull rod 411 outwards so that the end of the latch rod 404 enters the first rod groove 403. After the power connection plug rod 307 is inserted into the power connection slot 309, release the pull rod 411, so that the movable plate 402 moves back under the elastic force of the first spring 406, and the latch rod 404 is inserted into the card slot 405 on the power connection plug rod 307, which is convenient for clamping and fixing the two lamp strip bodies 1 and facilitating connection;

[0041] When it is necessary to adjust the distance between the two lamp bar bodies 1, turn the screw rod 518. Since the screw rod 518 is threadedly connected to the thread groove 517, and at the same time the positioning groove 410 on the movable circular plate 409 is clamped with the positioning block 414, after the screw rod 518 is turned, the first moving block 503 is pushed to move, and then the push rod 507 is pushed to move along the fifth rod groove 508 through the connecting rod 505, and then the power connection plug rod 307 is pushed to move, so as to adjust the distance between the end of the power connection plug rod 307 and the lamp bar body 1, thereby facilitating the adjustment of the distance between the two lamp bar bodies 1.
