[0027] like Figures 1 to 3 As shown, the present application discloses a light box, including a box body and a light bar 10, wherein the light bar 10 is arranged in the box body.

[0028] The box body is provided with a self-locking assembly, which includes an outer tube body 1, an inner tube body 2 and a self-locking member. The box body includes a box body 3 and a box cover 4, and the box cover 4 is covered on the box body 3. A first embedding groove 301 matching the inner tube body 2 is provided on the side of the box body 3, and both ends of the first embedding groove 301 are provided with openings and the first embedding groove 301 is arranged along the length direction of the side of the box body 3. A second embedding groove 302 is provided on the first embedding groove 301, and the second embedding groove 302 is interconnected with the first embedding groove 301, and the second embedding groove 302 matches the outer tube body 1. The inner tube body 2 is installed in the outer tube body 1, and the part of the inner tube body 2 exposed outside the outer tube body 1 is embedded in the first embedding groove 301, and the outer tube body 1 is embedded in the second embedding groove 302, and the end of the inner tube body 2 faces the opening of the first embedding groove 301. The width of the second embedding groove 302 is greater than the width of the first embedding groove 301. This structure can prevent the outer tube body 1 from moving back and forth. The box cover 4 is provided with an air avoidance hole 401 at a position corresponding to the second embedding groove 302, and one side of the outer tube body 1 is embedded in the air avoidance hole 401. The box body also includes a decorative panel 5, which covers the outer side of the box cover 4 and covers the air avoidance hole 401.

[0029] like Figures 4 to 7 As shown, the self-locking member is arranged between the outer tube body 1 and the inner tube body 2, and the self-locking member includes a ball 6 and an elastic member. The outer side wall of one end of the inner tube body 2 is provided with a first tapered surface 201, and the inner side wall of one end of the outer tube body 1 is provided with a second tapered surface 101 matching the first tapered surface 201. The side wall of the inner tube body 2 provided with the first tapered surface 201 is provided with at least two ball holes 202, and the ball holes 202 are provided with the ball 6 and both sides of the ball 6 are exposed outside the two sides of the ball holes 202. The elastic member is arranged between one end of the inner tube body 2 and the other end of the outer tube body 1, and the elastic member supports the inner tube body 2 to press the first tapered surface 201 against the second tapered surface 101. In this specific embodiment, the elastic member is a spring 7, and a plug 8 is provided in the other end of the outer tube body 1, and a through hole is provided in the middle of the plug 8. One end of the inner tube body 2 is provided with a protrusion 203, one end of the spring 7 is sleeved outside the protrusion 203, and the other end of the spring 7 is against the inner end surface of the plug 8. The other end of the inner tube body 2 is exposed outside one end of the outer tube body 1.

[0030] The self-locking component also includes an auxiliary tube 9, the outer diameter of which is smaller than the diameter of the first embedding groove 301. The auxiliary tube 9 can extend into the first embedding groove 301 and rest against the end face of the inner tube body 2. The auxiliary tube 9 is used when unlocking.

[0031] In this specific embodiment, the outer tube body 1, the inner tube body 2, the self-locking member and the hanging rope are all made of conductive metal materials, and the hanging rope is a steel wire rope. A wire 11 is connected between the outer tube body 1 and the light bar 10.

[0032] The present application discloses a light box. When installing, the hanging rope is aligned with the pipe mouth of the inner tube body 2 and inserted into the inner tube body 2. The hanging rope is blocked during the insertion process and pushes the inner tube body 2 to move inward. At this time, the ball 6 on the inner tube body 2 will be properly loosened. After the hanging rope is inserted into the inner tube body 2 and released, the spring 7 will lift the inner tube body 2. Under the action of the first conical surface 201 and the second conical surface 101, the ball 6 gathers inward to clamp the hanging rope, so that the hanging rope cannot be pulled out, which has a self-locking effect. When unlocking is required, the auxiliary tube 9 is inserted into the first embedding groove 301 and pressed against the end face of the inner tube body 2. At this time, the inner tube body 2 moves downward to compress the spring 7, and the ball 6 will also be loosened. At this time, the ball 6 has no clamping force on the hanging rope, and the hanging rope can be pulled out from the inner tube body 2. The hanging rope is convenient to disassemble and assemble.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the principles and spirit of the present application are included in the protection scope of the present application.
