DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5, A reinforced light-emitting character mechanism, comprising: a character housing 1 and a light-transmitting panel 2. The character housing 1 and the light-transmitting panel 2 are combined into a light-emitting character light box. The light-transmitting panel 2 is installed on the front of the character housing 1. Light-emitting diodes are installed as light sources between the character housing 1 and the light-transmitting panel 2. A connection box 3 is movably installed on the back of the character housing 1. Mounting ears 4 are fixed on the side of the connection box 3. Screw holes are provided on the mounting ears 4 to facilitate fixed connection with the position where the light-emitting character needs to be installed through bolts. A central gear 6 and a rack 7 are provided inside the connection box 3. Among them, the central gear 6 is rotatably installed at the center inside the connection box 3. Two racks 7 are provided symmetrically about the center of the central gear 6 and are meshed with the central gear 6. Vertical connecting rods 8 are perpendicularly connected to the ends of the two racks 7 away from each other. And a positioning rod 9 is perpendicularly installed on the connecting rod 8. The positioning rod 9 is parallel to the rack 7. When the central gear 6 rotates, the two positioning rods 9 can be driven to approach or move away from each other, so that the positioning rod 9 can extend out of the outer shell of the connection box 3 or retract into the connection box 3. Positioning holes 11 matching the two positioning rods 9 are provided on the character housing 1. When the positioning rod 9 is inserted into the positioning hole 11, the connection box 3 and the character housing 1 are connected and locked together. When the positioning rod 9 is removed from the positioning hole 11, the character housing 1 can be detached from the connection box 3. The disassembly and assembly are convenient and facilitate later maintenance. In order to facilitate the control of the rotation of the central gear 6, an adjustment handle 5 for driving the rotation of the central gear 6 is also installed on the back of the connection box 3 of the character housing 1.

[0022] In order to improve the stability when the connection box 3 is installed on the character housing 1, it is set that both the positioning hole 11 and the positioning rod 9 adopt a conical structure, so that before the positioning rod 9 is inserted into the positioning hole  11, it is easier to align with the positioning hole 11. After being inserted into the positioning hole 11, due to the tight fit between the conical surfaces of the positioning rod 9 and the positioning hole 11, its firmness is increased and it is not easy to shake.

[0023] In order to make the docking between the character housing 1 and the connection box 3 more convenient, it is set that an installation groove 12 for accommodating the connection box 3 is provided on the back of the character housing 1, and the connection surface between the connection box 3 and the installation groove 12 adopts a frustum of a pyramid structure, which is convenient for the connection box 3 to be embedded in the installation groove 12, making the whole connected light-emitting character thinner and lighter. The connection box 3 will not protrude from the character housing 1, and the integrity is more beautiful.

[0024] In order to improve the stability of the rack 7 during movement, it is set that a straight rail 31 is fixed on the inner wall of the connection box 3, and a matching sliding groove 71 is provided on the side of the rack 7 close to the straight rail 31. Through the sliding limit function of the straight rail 31 and the sliding groove 71, the rack 7 is not easy to deviate during movement.

[0025] In order to further improve the stability after connection, a slot 61 is provided at one end of the central gear 6 extending out of the back surface of the connection box 3, and a plug rod 52 inserted into the slot 61 is fixed at the center of the adjusting handle 5. The plug rod 52 and the slot 61 adopt a non-circular structure, so that the plug rod 52 can stretch inside the slot 61. At the same time, when the plug rod 52 rotates, it can drive the central gear 6 to rotate. A limiting ring 51 is also fixed on the back surface of the connection box 3. The limiting ring 51 is located between the adjusting handle 5 and the back surface of the connection box 3. The end surface of the limiting ring 51 opposite to the adjusting handle 5 is engaged with teeth to limit it and prevent it from rotating. When the adjusting handle 5 is away from the limiting ring 51, the locking state can be released, which is convenient for rotating and controlling the central gear 6. A spring 53 is sleeved outside the plug rod 52. One end of the spring 53 is fixed to the back surface of the connection box 3, and the other end of the spring 53 is rotatably connected to the adjusting handle 5 through a bearing. The elastic action of the spring 53 can pull the adjusting handle 5 to tightly hold the limiting ring 51, thereby effectively preventing the possibility of accidental touch.

[0026] In order to improve the strength of the entire light-emitting character, a reinforcing plate 10 is covered on the outside of each external corner of the character housing 1. The reinforcing plate 10 adopts a right-angle plate, making it not easy to be knocked and deformed.

[0027] The working principle is as follows: First, connect and fix the mounting ear 4 to the hanging rack in the area to be installed through bolts. Then rotate the adjusting handle 5 to retract the positioning rod 9 into the connection box 3. Then buckle the character housing 1 outside the connection box 3 so that the connection box 3 is embedded in the mounting groove 12. Then rotate the adjusting handle 5 in the reverse direction to make the positioning rod 9 extend out of the connection box 3 and insert into the positioning hole 11, and the installation connection between the connection box 3 and the character housing 1 can be completed.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
