Technical Field
[0001] This utility model relates to the field of power bank technology, and in particular to a retractable power bank that is easy to assemble. Background Technology
[0002] A power bank, also known as a portable power bank or mobile power supply, is a small electronic device that can be carried around to provide additional power to smartphones, tablets, laptops, and other USB charging devices. Power banks typically contain lithium-ion or lithium polymer batteries with capacities ranging from several thousand mAh to tens of thousands of mAh, which determines how many times they can charge other devices.
[0003] To accommodate different phone models, existing power banks require multiple charging ports, such as dual charging cables or multi-port cables, which are costly to manufacture. Therefore, we propose a retractable cable power bank that is easy to assemble to solve this problem. Summary of the Invention

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.
[0024] Please refer to Figures 1-5 This utility model proposes an easy-to-assemble retractable power bank, including an outer shell 1 and a cover 2. A partition 3 is fixedly installed on the bottom inner wall of the outer shell 1, and a storage shell 4 is fixedly installed on the top of the partition 3. The storage shell 4 is circular, and a storage tray 5 is rotatably installed at the center of the storage shell 4. A charging cable 6 is wound around the outside of the storage tray 5. One end of the charging cable 6 is fixedly connected to the storage tray 5, and the other end of the charging cable 6 extends through the outer shell 1 to the outside of the outer shell 1 and is provided with a charging head mechanism. The charging head includes a first connector 7, a rubber soft band 8 is fixedly connected to one side of the first connector 7, and a second connector 9 is fixedly connected to one end of the rubber soft band 8.
[0025] like Figure 4 and Figure 5 As shown, multiple external plates 10 are provided around the inner wall of the outer shell 1. A slot is provided on one side of the external plate 10. Multiple toothed plates 11 are provided on one side of the cover 2. A locking plate 12 is fixedly installed on one side of several of the toothed plates 11. The locking plate 12 is adapted to the corresponding slot. The locking plate 12 and the slot cooperate to form a snap-fit structure, which facilitates the quick installation and disassembly of the outer shell 1 and the cover 2, thereby facilitating assembly and maintenance.
[0026] like Figure 3 and Figure 4 As shown, the top of the storage shell 4 is movably abutted against the storage cover 13, and the storage tray 5 is provided with a ratchet latching mechanism.
[0027] A T-shaped sleeve 14 is fixedly installed on the top of the partition 3 by screws. The T-shaped sleeve 14 is slidably fitted on the outside of the storage cover 13 and the storage shell 4. A through hole 15 is opened on one side of the storage cover 13, the shell cover 2 and the T-shaped sleeve 14. The same button is set in multiple through holes 15, and the button cooperates with the ratchet buckle mechanism.
[0028] It should be noted that the storage tray 5 is equipped with a pre-tensioned spiral spring. When the user pulls out the charging cable 6, tension is applied to the spiral spring, causing it to compress or twist further. When the charging cable 6 is released, the spiral spring will generate a reverse force as it tries to return to its natural state, thereby driving the storage tray 5 to rotate and automatically winding the charging cable 6 back into the power bank.
[0029] To further explain, the ratchet locking mechanism ensures that the cable can be pulled out and held to the required length, while also allowing it to be easily retracted when not in use. When the user stops pulling and releases the cable, the ratchet locks the gear structure, preventing the coil spring from automatically winding the charging cable 6 back. The user can release the ratchet's locking state by pressing the button, allowing the coil spring to wind the charging cable 6 back.
[0030] like Figure 2 As shown, an elliptical hole is provided on one side of the outer shell 1, and an elliptical sleeve 16 is fixedly installed in the elliptical hole. A wire placement groove 17 is provided on one side of the outer shell 1, and the inner wall of one side of the wire placement groove 17 is connected to the elliptical hole. The charging head mechanism is movably engaged in the wire placement groove 17.
[0031] The first connector 7 is a Type-C connector, and the second connector 9 is an Apple connector. One side of the Apple connector is an adapter that is compatible with the Type-C connector. The adapter is a Type-C female port used to insert the Type-C connector, thereby converting the Type-C connector into an Apple connector and saving costs.
[0032] like Figure 2 and Figure 4 As shown, a circuit board is provided on the bottom inner wall of the outer casing 1, two batteries 18 are provided above the circuit board, and a charging interface 19 is provided on one side of the outer casing 1 to realize the charging and energy storage function of the power bank.
[0033] like Figure 4 As shown, a cavity is provided on the outer side of the outer shell 1. Two external connecting holes 20 are provided on the inner wall of one side of the cavity. The same connecting line 21 is wound inside the two external connecting holes 20. One end of the connecting line 21 is fixedly connected to a hanging ornament 22 to facilitate lifting the power bank.
[0034] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
