[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, this utility model provides a double-helix heating wire electric blanket with uniform heating, including a double-helix heating wire electric blanket 1. A connecting wire 2 is fixedly connected to the outer side of the double-helix heating wire electric blanket 1. Two connecting wires 2 are provided, and a controller 3 is fixedly connected between the two connecting wires 2. A plug 4 is fixedly connected to the end of the connecting wire 2. A winding assembly is provided on the outer side of the double-helix heating wire electric blanket 1. The winding assembly includes a connecting cloth 5 fixedly connected to the outer side of the double-helix heating wire electric blanket 1. A winding roller 6 is fixedly connected to the outer side of the connecting cloth 5. Two pressing discs 7 are slidably connected inside the winding roller 6. The two pressing discs 7 are arranged opposite to each other. A pulling rod 8 is rotatably connected to the outer side of the pressing discs 7. The pulling rod 8 passes through the winding roller 6 and is movably connected to the winding roller 6. A handle 9 is rotatably connected inside the pulling rod 8. Two limiting blocks 10 are fixedly connected to the outer side of the pulling rod 8. The limiting blocks 10 pass through the winding roller 6 and are slidably connected to the winding roller 6. A first spring 11 is fixedly connected between the outer side of the pressing discs 7 and the inside of the winding roller 6.

[0023] By rotating the pressing disc 7, the winding roller 6 is driven to rotate, thereby winding up the connecting cloth 5 and the double-helix heating wire electric blanket 1. After winding is completed, the handle 9 can be pulled to move the pulling roller 8, thereby squeezing the first spring 11. Then, the handle 9 is rotated to drive the limiting block 10 to rotate. After rotating to a certain position, the handle is released, thereby driving the pressing disc 7 to move through the first spring 11. The pressing disc 7 covers the end of the wound double-helix heating wire electric blanket 1 and fixes its position to complete the winding. By winding in this way, the heating wire inside the double-helix heating wire electric blanket 1 will not be folded, thereby reducing the possibility of damage to the heating wire and improving the safety of use.

[0024] Among them, the outer side of the pulling rod 8 is provided with a pushing component, which includes two connecting pieces 12 rotatably connected to the outer side of the two pulling rods 8, and a rotating rod 13 is fixedly connected between the two connecting pieces 12. Two plastic clips 14 are rotatably connected to the outer side of the rotating rod 13.

[0025] By pushing the rotating roller 13, power is transmitted to the connecting piece 12, thereby driving the pressing plate 7 to rotate, which in turn drives the winding roller 6 to rotate.

[0026] One of the plastic clips 14 has a first placement component on its outer side. The first placement component includes a first placement frame 15 fixedly connected to the outer side of the plastic clip 14. The first placement frame 15 is slidably connected to four slide rods 16. The four slide rods 16 are divided into two groups, and the ends of the two groups of slide rods 16 are fixedly connected to a connecting plate 19.

[0027] The first placement assembly also includes a pressing plate 17 fixedly connected to the end of the slide bar 16, and a second spring 18 is fixedly connected between the outer side of the pressing plate 17 and the inside of the first placement frame 15.

[0028] By moving the controller 3 into the first placement frame 15, the pressing plate 17 is pushed, which in turn moves the slide bar 16, which in turn squeezes the second spring 18. When the controller 3 moves to the designated position, the second spring 18 will drive the pressing plate 17 to press and clamp the controller 3, thereby fixing the position of the controller 3 and completing the storage.

[0029] The second plastic clip 14 has a second placement component on its outer side. The second placement component includes a second placement frame 20 fixedly connected to the outer side of the plastic clip 14. Two rubber baffles 21 are fixedly connected inside the second placement frame 20.

[0030] By moving the plug 4, the rubber stop plate 21 is pushed. When the plug 4 enters the second placement frame 20, the rubber stop plate 21 can restrict the position of the plug 4, thereby completing the storage.

[0031] The two rubber baffles 21 are positioned vertically and are positioned opposite each other.

[0032] The position of the plug 4 can be restricted by the rubber stop plate 21, thereby completing the storage of the plug 4.

[0033] The working principle and usage process of this utility model are as follows: By rotating the pressing plate 7, the winding roller 6 is driven to rotate, thereby winding up the connecting cloth 5 and the double-helix heating wire electric blanket 1. After winding is completed, the handle 9 can be pulled, thereby driving the pulling roller 8 to move, thereby squeezing the first spring 11. Then, the handle 9 is rotated, thereby driving the limiting block 10 to rotate. After rotating to a certain position, the handle is released, thereby driving the pressing plate 7 to move through the first spring 11. The pressing plate 7 covers the end of the wound double-helix heating wire electric blanket 1 and fixes its position, thus completing the winding. By winding in this way, the heating wire inside the double-helix heating wire electric blanket 1 will not be folded, thereby reducing the possibility of damage to the heating wire and improving the safety of use.
