[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, a lithium battery power supply device for camping decorative string lights includes a main body 1. The main body 1 includes a protective shell 2, a serial interface assembly 3, a lithium battery pack 4, a charging interface 5, function buttons, and status indicator lights 6. The lithium battery pack 4 is built into the protective shell 2. The serial interface assembly 3 is located on the top of the main body 1 and includes a threaded connection part 7 and a conductive socket 8. The conductive socket 8 is located inside the threaded connection part 7. A base 9 is provided at the bottom of the main body 1, and a rope fixing mechanism 10 is installed inside the base 9. The rope fixing mechanism 10 includes a fixing slot 11. The system includes a detachable connecting plate 12, a rope 14, a winding reel 13, and a spring 15. A fixing slot 11 is located at the bottom of the base 9. One end of the detachable connecting plate 12 is inserted into the fixing slot 11. A fixing hole is provided at the bottom of the detachable connecting plate 12. The top of the detachable connecting plate 12 is fixedly connected to the rope 14. The rope 14 is wound around the winding reel 13. Both ends of the winding reel 13 are movably mounted inside the base 9 via a pivot. The spring 15 is installed on one side of the winding reel 13 to provide elastic deformation. A locking mechanism is installed on one side of the winding reel 13.

[0026] Furthermore, the locking mechanism includes a toothed disc 16, a locking pin 17, a spring 18, and a button 19. The toothed disc 16 is fixedly installed on one side of the winding reel 13, and the center of the toothed disc 16 and the center of the winding reel 13 are located in the same axial direction. A slanted locking tooth 20 is provided on one side surface of the toothed disc 16.

[0027] In this embodiment, one end of the locking pin 17 is elastically connected to the inner wall of the base 9 via a spring 18, and the other end engages with the oblique teeth 20 on the gear disc 16 to achieve the locking and unlocking functions of the winding reel 13. A button 19 is located on the outside of the base 9 and is fixedly connected to one end of the locking pin 17. Pressing the button 19 drives the locking pin 17 to move axially, thereby disengaging from or engaging with the oblique teeth 20, thus adjusting and fixing the length of the rope 14.

[0028] Furthermore, one end of the locking pin 17 has an L-shaped structure, and the locking pin 17 is engaged with one side of the oblique locking tooth 20.

[0029] In this embodiment, the L-shaped structure design of the locking pin 17 can more accurately cooperate with the oblique locking teeth 20, ensuring uniform and stable force during the locking process.

[0030] Furthermore, the spring 18 is sleeved on the outside of the locking pin 17, one side of the button 19 is fixedly connected to the locking pin 17, and the button 19 is installed on one side of the base 9.

[0031] In this embodiment, the design of the spring 18 ensures that the locking pin 17 can automatically reset when no external force is applied, thus ensuring the stability and reliability of the locking mechanism.

[0032] Furthermore, the protective shell 2 is made of ABS+PC composite waterproof material, and the protective shell 2 has an overall cuboid structure.

[0033] In this embodiment, the choice of ABS+PC composite waterproof material gives it excellent waterproof performance, which can effectively protect internal components from the effects of a humid environment.

[0034] Furthermore, the charging port 5, function buttons and status indicator lights 6 are located on the front of the protective shell 2, and the charging port 5 is equipped with a waterproof and dustproof plug.

[0035] In this embodiment, the waterproof and dustproof plug design of the charging interface 5 can effectively prevent dust and moisture from entering, thereby extending the service life of the device.

[0036] Furthermore, the conductive socket 8 is provided with positive and negative terminals, which are connected to the lithium battery pack 4 circuit via wires.

[0037] In this embodiment, the conductive socket 8 is connected to the camping decorative light. The tight fit of the threaded connection part 7 ensures a stable connection between the conductive socket and the light string, while avoiding poor contact caused by loosening.

[0038] Furthermore, a number of lighting lamps 23 are installed at the top of the main body 1, and the lighting lamps 23 are distributed at the four corners of the threaded connection part 7.

[0039] In this embodiment, the distribution design of the lighting lamps 23 not only enhances the overall aesthetics but also provides uniform light coverage, meeting the lighting needs of various scenarios.

[0040] Furthermore, a waterproof sealing ring 24 is provided at the bottom of the threaded connection 7.

[0041] In this embodiment, the waterproof sealing ring 24 can effectively prevent water from entering, thereby improving the reliability and safety of the equipment in complex environments.

[0042] Furthermore, the function buttons include a power switch button 21 and a dimming button 22. The power switch button 21 is used to control the overall on / off state of the device, and the dimming button 22 can cycle through the high, medium, and low brightness levels of the light string.

[0043] In this embodiment, the design of the dimming button 22 allows users to flexibly adjust the lighting brightness according to actual needs, thereby achieving a balance between energy saving and lighting effect.

[0044] The working principle of this utility model is as follows:

[0045] When connecting camping decorative light strings, the threaded connector 7 fits tightly with the light strings, and the positive and negative terminals on the conductive socket 8 transmit power to the light strings through wires, ensuring their normal operation. Meanwhile, the waterproof sealing ring 24 effectively prevents moisture intrusion, ensuring the stability of the equipment in complex outdoor environments.

[0046] When it is necessary to fix the main body 1, the detachable connecting plate 12 can be removed, the rope 14 can be pulled out from the winding wheel 13, and the detachable connecting plate 12 can be fixed to the external support through the fixing hole. The locking mechanism locks the length of the rope 14 through the cooperation of the gear plate 16 and the locking pin 17, ensuring that the main body 1 remains stable during use.

[0047] Users can unlock the locking mechanism by pressing button 19 and adjust the length of rope 14 to suit different installation environments. After releasing button 19, spring 18 pushes locking pin 17, causing locking pin 17 to disengage from gear plate 16. Under the elastic deformation of spring 15, excess rope 14 can be automatically retracted, which can easily fix the main body 1. At the same time, rope fixing mechanism 10, together with lighting lamp 23, can suspend lighting lamp 23 at different heights.

[0048] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
