Spiral protrusions 201 are evenly provided on the winding roller 2, and a spiral wire groove is formed between the spiral protrusions 201.

[0025] When in use, the outer shell 1 of the storage device is made of PC / ABS alloy, which has good impact resistance and deformation resistance. The winding roller 2 used for winding is made of silicone material, which is wear-resistant and insulating. Multiple spiral protrusions 201 are set on the winding roller 2 to form a guide groove, which can further prevent the power cord 11 from becoming loose.

[0026] A fixing post 4 is provided at one end of the outer side of the end cap 3, and a fixing plate 8 is connected to the bottom end of the fixing post 4;

[0027] The fixing plate 8 is provided with fixing holes, and the outer side of the storage shell 1 is provided with limiting holes. When the end cap 3 is placed on the top of the storage shell 1, the fixing holes and limiting holes are aligned.

[0028] Specifically, such as Figure 1 As shown, when in use, the fixing post 4 is inserted into the limiting groove 5, the fixing hole on the fixing plate 8 corresponds to the limiting hole on the housing 1 of the storage device, and then the fixing pin is used to fix it, so as to close the end of the housing 1 of the storage device.

[0029] The top of the end cap 3 is provided with a power socket 6 and a switch button 7;

[0030] The top of the end cap 3 is provided with multiple power sockets 6, which are in a specific shape and evenly distributed.

[0031] Specifically, such as Figure 1 , Figure 2 As shown, when in use, different devices can be compatible in one stop through the different sockets on the end cap 3, reducing the number of sockets used and making the placement more tidy;

[0032] The back of the storage container housing 1 is provided with a hook 9;

[0033] A wire hole 101 is provided at one end of the outer side of the storage housing 1, and the power cord 11 extends from the wire hole 101 to the outside of the storage housing 1.

[0034] Specifically, such as Figure 2 , Figure 5As shown, when the storage unit housing 1 needs to be hung on the wall, the hook 9 can be removed and hung on the wall. The extra part of the power cord 11 can enter through the wire hole 101 and be wound along the winding roller 2. The power cord 11 is inside, making the outside look neater and cleaner, and convenient for storage.

[0035] The bottom end of the winding roller 2 is provided with a winding assembly. The winding assembly includes a rotating shaft 1301 rotatably connected to the inside of the housing 1 of the receiver. A worm gear 13 is fixedly sleeved on the outside of the rotating shaft 1301. A worm 12 is provided on one side of the worm gear 13. The worm 12 and the worm gear 13 mesh with each other. The meshing of the worm 12 and the worm gear 13 is fixed. One end of the worm 12 extends to the outside of the housing 1 of the receiver and is fixed with a handle.

[0036] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, in use, the handle extending from the outer casing 1 of the worm gear 12 is rotated, causing the worm gear 12 to rotate. The worm gear 12 meshes with the worm wheel 13, causing the worm wheel 13 to rotate synchronously, which in turn causes the winding roller 2 at the top of the rotating shaft 1301 to rotate. The power cord 11 winds along the spiral protrusion 201 on the winding roller 2. The meshing of the worm gear 12 and the worm wheel 13 is continuous. When the winding reaches a certain length, it is fixed by the elastic buckle 10. The transmission of the worm gear 12 and the worm wheel 13 has self-locking properties, which can effectively prevent the power cord 11 from becoming loose.

[0037] Working principle: When using this utility model, firstly, the extra part of the power cord 11 can enter through the wire hole 101 and wind along the winding roller 2. Rotate the handle extending from the worm 12 to the outside of the housing 1, driving the worm 12 and worm wheel 13 to rotate, causing the winding roller 2 at the top of the rotating shaft 1301 to rotate. The power cord 11 winds along the spiral protrusion 201 on the winding roller 2. The meshing of the worm 12 and worm wheel 13 is continuous, and the relative sliding speed between the meshing tooth surfaces is high, which makes the transmission process smoother and reduces impact and vibration.

[0038] Secondly, after being wound to a certain length, it is fixed by the elastic buckle 10. Then, the fixing post 4 is moved to the limiting groove 5. The fixing hole on the fixing plate 8 corresponds to the limiting hole on the housing 1 of the storage device. Then, it is fixed by the fixing pin, thereby fixing the power cord 11 in the housing 1 of the storage device.

[0039] Finally, plug the plug on the power cord 11 into the power source, turn on the switch button 7, and the indicator light on the end cover 3 will light up, and the device can be used. When the storage unit shell 1 needs to be hung on the wall, take out the hook 9 and hang it on the wall for easy placement.
