[0001] The utility model relates to the technical field of LED light strips, in particular to a hard light strip structure that can be quickly disassembled and assembled. Background Art

[0002] At present, the products on the market are provided with screw holes on the LED light strips. When in use, the product needs to be held, and then the light strip is fixed on the light box body by aligning the screw holes. Each time an additional strip is added, screws need to be re-drilled and fixed. If the installation position is inappropriate, the screws can only be removed to reinstall. In addition, when disassembling after use, only the screws can be removed one by one to remove the light strip, which will damage the light box body, causing the box body to not be reused multiple times, and also requires a large amount of manual operation. Another method is to use double-sided tape attached to the back of the LED light strip. When in use, the release paper of the double-sided tape is torn off and directly pasted on the side of the light box body. Once installed, if the pasting position is incorrect, it is very difficult to disassemble and move, and it cannot be disassembled and reused after use. Therefore, the existing light strip structure should be improved to solve the above problems. Summary of the Utility Model

[0026] The present utility model is as Figures 1 to 7 shown, a hard light bar structure that can be quickly disassembled and assembled, including a fixing knob 10, a box body 20, a housing 30 and a circuit control board 40, wherein:

[0027] The circuit control board 40 is located inside the housing 30, the housing 30 is locked to the box body 20 by the fixing knob 10, and the circuit control board 40 is located between the housing 30 and the box body 20; the fixing knob 10 includes a handle 11 and a T-shaped boss 12, and the T-shaped boss 12 is located at the lower end of the handle 11; a T-shaped groove 21 for cooperating with the T-shaped boss 12 is longitudinally formed on the box body 20; a first protruding hole 31 corresponding to the fixing knob 10 is provided on the housing 30, and the handle 11 extends out from the first protruding hole 31; a second protruding hole 41 corresponding to the fixing knob 10 is provided on the circuit control board 40, and the T-shaped boss 12 extends downward from the second protruding hole 41 and is detachably clamped in the T-shaped groove 21.

[0028] A plurality of T-shaped grooves 21 are arranged longitudinally and side by side on the box body 20. During application, one of the T-shaped grooves 21 can be selected for installation, or multiple T-shaped grooves 21 can be installed simultaneously.

[0029] An annular fixing piece 13 is further arranged at the lower end of the handle 11, and the annular fixing piece 13 is located between the handle 11 and the T-shaped boss 12; a limiting annular groove 32 corresponding to the annular fixing piece 13 is arranged on the inner top wall of the outer shell 30. The annular fixing piece 13 can be rotatably embedded in the limiting annular groove 32 along with the handle 11 to limit the annular fixing piece 13 and prevent it from shaking left and right. A recessed part 33 corresponding to the fixing knob 10 is arranged on the outer shell 30, and the opening of the recessed part 33 is in an inverted T shape with a wider upper part and a narrower lower part, so as to accommodate the manual installation operation of the staff; the first protruding hole 31 is located at the bottom of the recessed part 33; the limiting annular groove 32 is located on the inner top wall of the recessed part 33 and is communicated with the first protruding hole 31. Both ends of the T-shaped boss 12 on the side close to the annular fixing piece 13 are in the shape of inclined surfaces 121, and the inclination directions of the inclined surfaces 121 at both ends are opposite. Such a design enables the upper end surface of the T-shaped boss 12 to gradually press tightly when contacting the inner top wall of the T-shaped groove 21 along with the rotation of the handle 11, making the combination of the hard light strip and the box body 20 tighter.

[0030] Positioning columns 42 are arranged on the circuit control board 40, and positioning sleeves 34 corresponding to the positioning columns 42 are arranged on the inner wall of the outer shell 30.

Solder the LED lamp beads 44 and other components onto the substrate 43 of the circuit control board 40 with solder paste. Pass the T-shaped boss 12 of the fixing knob 10 downward through the second protruding hole 41 on the substrate 43, pass the handle 11 through the first protruding hole 31 on the outer shell 30, and fix the annular limiting plate through the limiting ring groove 32 of the outer shell 30 to accurately position the fixing knob 10 so that it will not displace or shake left and right during rotation. Then insert the positioning post 42 on the substrate 43 into the positioning sleeve 34 on the outer shell 30, and then lock the substrate 43 to the outer shell 30 with screws. The positioning post 42 is tightly fixed in the positioning sleeve 34. Finally, lock the outer shell 30 and the substrate 43 together by aligning the bottom of the substrate 43 upward with the positioning post 42 and locking the screws, so that the outer shell 30, the circuit control board 40 and the fixing knob 10 are combined to form a rigid light bar. The fixing knob 10 is also clamped between the outer shell 30 and the circuit control board 40 and will not fall off.

[0034] During application, just rotate the T-shaped boss 12 of the fixing knob 10 to a direction parallel to the rigid light bar, then bring the rigid light bar close to the box body 20, insert the T-shaped boss 12 into the T-shaped groove 21 of the box body 20, and then rotate the fixing knob 10 to a direction perpendicular to the rigid light bar. At this time, the T-shaped boss 12 is clamped in the T-shaped groove 21, and the rigid light bar is locked to the light box body 20. When disassembling, just twist the handle 11 to easily remove it. If the installation position is inappropriate, just rotate the fixing knob 10 to remove the rigid light bar and reinstall it to the appropriate position.
