[0040] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0041] Example 1:

[0042] As Figures 1-3 shown, a portable LED light board includes a first housing 1 and a second housing 2.

[0043] A rotating shaft 5 is rotatably connected to the inner wall of the first housing 1. An LED light strip 4 is wound around the outer wall of the rotating shaft 5. The other end of the LED light strip 4 penetrates through the first housing 1 and is fixed to the inner wall of the second housing 2 by a fixing plate 7. A rotating cylinder 6 for guiding the LED light strip 4 is rotatably connected to the inner wall of the first housing 1. Wrist strap assemblies 3 are provided on both sides of the first housing 1 and the second housing 2. A winding assembly for winding the LED light strip 4 is provided inside the first housing 1.

[0044] When in use, first hold the first housing 1 and the second housing 2 with both hands and move them to both sides, thereby increasing the distance between the first housing 1 and the second housing 2, so that the LED light strip 4 is gradually pulled out, and the required text or image is displayed by the LED light strip 4; after use, the winding assembly is used to wind up the LED light strip 4, and at the same time the first housing 1 and the second housing 2 gradually approach each other.

[0045] By providing the first housing 1, the second housing 2 and the LED light strip 4, when not in use, the LED light strip 4 can be retracted into the first housing 1 and the second housing 2, thereby reducing the overall space occupancy rate, being more convenient to carry and store, and improving the use convenience of the device.

[0046] As Figure 3 、 4 shown, a storage battery 8 is provided inside the second housing 2. The storage battery 8 is connected to a circuit board through an integrated wire harness. The circuit board is fixedly installed on the inner wall of the second housing 2. A control switch assembly 9, an indicator light group 10 and a charging port 11 are provided on the outer wall of the second housing 2. The LED light strip 4, the control switch assembly 9 and the indicator light group 10 are all connected to the circuit board through an integrated wire harness, and the charging port 11 is connected to the storage battery 8 through an integrated wire harness.

[0047] Insert a charger adapted to the charging port 11 into the charging port 11 to supply power to the storage battery 8. The indicator light group 10 can be used for indication. For example, the charging state of the storage battery 8 or the display state of the LED light strip 4, that is: when the battery is low, during charging and after charging, the indicator light group 10 shows different colors to prompt the user of the current battery 8 power situation; the control switch assembly 9 can also be used to change the image or text displayed by the LED light strip 4. Different images or texts correspond to different colors or the number of lit indicator lights of the indicator light group 10, etc. All of the above can be changed and adjusted according to actual production requirements.

[0048] As Figure 1 、 4As shown, the wristband assembly 3 includes an elastic band 12 and an auxiliary plate 13. The elastic band 12 is movably inserted through the inner wall of the auxiliary plate 13, and both ends of the elastic band 12 penetrate through the first housing 1 and the second housing 2 and are fixedly connected to the inner walls of the first housing 1 and the second housing 2. The material of the auxiliary plate 13 is preferably silicone.

[0049] One can insert the hand between the auxiliary plate 13 and the first housing 1 or the second housing 2, and then hold the first housing 1 and the second housing 2 with both hands, so that the entire LED light sign can be lifted with both hands to support or interact with the performer.

[0050] By providing the elastic band 12 and the auxiliary plate 13, the device of the present invention enables the user to more conveniently lift the device by the cooperation of the elastic band 12 and the auxiliary plate 13, and the elastic property of the elastic band 12 can drive the auxiliary plate 13 to approach the first housing 1 and the second housing 2 when not in use, thereby further improving the convenience of use of the device.

[0051] In this embodiment: when the device is not in use, the first housing 1 and the second housing 2 approach each other. At this time, the overall idle occupancy rate of the device is relatively low and it is easy to carry. When in need of use, the user first tightly holds the two auxiliary plates 13 with both hands, and then uses the auxiliary plates 13 to pull the first housing 1 and the second housing 2 to both sides. At the same time, the LED light strip 4 is gradually pulled out. Subsequently, according to the need, the control switch assembly 9 is used to adjust the images, texts, etc. presented by the LED light strip 4. After the adjustment is completed, the device can be lifted by holding the two auxiliary plates 13 with both hands, so that it can support the performer or interact with him / her. After use, the retracting assembly can be used to retract the LED light strip 4. At the same time, the user loosens the grip on the two auxiliary plates 13 and assists the first housing 1 and the second housing 2 to approach each other as the LED light strip 4 is retracted.

[0052] When the battery 8 is short of power and needs to be charged, a charger adapted to the charging port 11 is connected to the charging port 11 to supply power to the battery 8. When the battery is low, charging, or charging is completed, the indicator light group 10 will present different light colors or the number of lit lights to prompt the user of the current power status of the battery 8.

[0053] Embodiment 2:

[0054] A portable LED light sign. The following improvements are made in this embodiment based on Embodiment 1, as Figure 5 shown:

[0055] The winding component includes a fixed cover 14 and a volute spring 15. The fixed cover 14 is fixedly installed on the upper surface of the bottom of the first housing 1. The rotating shaft 5 is rotatably connected to the inner wall of the fixed cover 14. Both ends of the volute spring 15 are fixedly connected to the fixed cover 14 and the rotating shaft 5 respectively. When both hands tightly hold the first housing 1 and the second housing 2 and pull the first housing 1 and the second housing 2 to both sides, the LED light strip 4 is gradually pulled out and drives the rotating shaft 5 to rotate, causing the volute spring 15 to undergo elastic deformation under force. When loosening the grip on the first housing 1 and the second housing 2, at this time, the pulling force of the user on the first housing 1 and the second housing 2 is less than the elastic force of the volute spring 15, causing the volute spring 15 to drive the rotating shaft 5 to reverse, thereby enabling the winding of the LED light strip 4.

[0056] As Figure 6 , 7 shown, a pressing block 16 is slidably fitted to the inner wall of the top of the first housing 1, and a first fixed cylinder 17 is fixedly connected to the lower surface of the top of the first housing 1. A compression spring 21 is buckled between the opposite sides of the pressing block 16 and the first fixed cylinder 17.

[0057] A tooth 19 is fixedly connected to the top of the rotating shaft 5. A tooth groove 20 adapted to the tooth 19 is provided in the inner wall of the pressing block 16, and an avoidance groove 18 is provided in the inner wall of the pressing block 16 above the tooth groove 20.

[0058] Press down the pressing block 16 to disengage the tooth groove 20 from the tooth 19, so that the tooth 19 is located in the avoidance groove 18, and the compression spring 21 is compressed under force. At this time, since the rotating shaft 5 is not restricted by the tooth 19 and the tooth groove 20, it can rotate freely. After the LED light strip 4 is pulled out, the pressing block 16 can be released. The compression spring 21 uses its own elasticity to push the pressing block 16 upward, so that the tooth 19 and the tooth groove 20 are engaged again, thereby restricting the rotation of the rotating shaft 5 and enabling the LED light strip 4 to maintain the current extended length unchanged.

[0059] In this embodiment: Before the user pulls out the LED light strip 4, it is necessary to tightly hold the two auxiliary plates 13, and one of the hands needs to long-press the pressing block 16 downward to disengage the tooth 19 from the restriction of the tooth groove 20. At this time, the tooth 19 is located in the avoidance groove 18, the rotating shaft 5 can rotate freely, and the compression spring 21 is compressed under force. Subsequently, the user pulls the auxiliary plates 13 to both sides, driving the first housing 1 and the second housing 2 to move to both sides, thereby gradually pulling out and unfolding the LED light strip 4. Under the rotation of the rotating shaft 5, the volute spring 15 undergoes elastic deformation. After the LED light strip 4 is completely pulled out, first release the pressing block 16. The compression spring 21 uses its own elasticity to push the pressing block 16 upward, so that the tooth groove 20 and the tooth 19 are engaged with each other, thereby restricting the rotation of the rotating shaft 5 and enabling the LED light strip 4 to maintain the current extended length; when it is necessary to wind the LED light strip 4, long-press the pressing block 16 again and loosen the grip on the two auxiliary plates 13, and use the volute spring 15 to drive the rotating shaft 5 to rotate in the reverse direction, thereby realizing the winding of the LED light strip 4.

[0060] This device is provided with a scroll spring 15, teeth 19, and tooth grooves 20. By utilizing the characteristics of the scroll spring 15 itself, it can achieve the winding of the LED light strip 4. Moreover, the cooperation of the teeth 19 and the tooth grooves 20 can restrict the rotation of the rotating shaft 5, thereby achieving the locking of the rotating shaft 5 and preventing the user from having to resist the elastic force of the scroll spring 15 for a long time, which may cause muscle fatigue.

[0061] Embodiment 3:

[0062] A portable LED light sign. Based on Embodiment 1, the following improvements are made in this embodiment, as Figures 8-10 shown:

[0063] The winding assembly includes a fixed cylinder two 22 fixed to the lower surface of the top of the housing one 1 and a motor 23 fixedly installed on the inner wall of the fixed cylinder two 22. The output shaft of the motor 23 is fixedly connected to the rotating shaft 5 through a coupling.

[0064] The outer wall of the bottom of the fixed cylinder two 22 is fixedly connected with a slip ring 24. The fixed end of the slip ring 24 is connected to the motor 23 through an integrated wire harness. The movable end of the slip ring 24 is fixedly connected to the rotating shaft 5, and the movable end of the slip ring 24 is connected to the LED light strip 4 through an integrated wire harness.

[0065] In this embodiment: The control switch assembly 9 is used to control the opening and closing of the motor 23 and the display state of the LED light strip 4. When the motor 23 drives the rotating shaft 5 to rotate and drive the LED light strip 4 to extend, the LED light strip 4 is in an on state. When the motor 23 drives the rotating shaft 5 to rotate in the reverse direction to drive the LED light strip 4 to wind up, the LED light strip 4 is in an off state.

[0066] This device is provided with a motor 23. By using the motor 23 to drive the forward and reverse rotation of the rotating shaft 5, the unwinding and winding of the LED light strip 4 are realized, simplifying the manual operation steps, and further improving the convenience of use of the device.

[0067] Embodiment 4:

[0068] A portable LED light sign. Based on Embodiment 1, the following improvements are made in this embodiment, as Figure 11 , 12 shown:

[0069] One end of the LED light strip 4 is provided with a magic tape 25 or a cable tie 26. The storage battery 8 is installed in the rotating shaft 5, and a circuit board is provided in the rotating shaft 5. A control switch assembly 9 and a charging port 11 are provided on the outer wall of the top of the rotating shaft 5. The LED light strip 4, the storage battery 8, the control switch assembly 9, and the charging port 11 are all connected to the circuit board through an integrated wire harness.

[0070] After winding the LED light strip 4 around the rotating shaft 5, the positive and negative sides of the LED light strip can be pasted and fixed by using the magic tape 25, or bundled and fixed by using the cable tie 26, so that the device is lighter and further improves the portability of the device.

[0071] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention.
