Problems solved by technology

[0003] However, the above-mentioned wire reels are all wired wire reels, that is, it is necessary to fix one end of the wires of earphones, mice, keyboards, chargers and other products in the wire reel, resulting in a wire reel that can only be used in On one product, the scope of use of the wire reel is limited; moreover, when the existing wire reel is in use, it is easy to cause the wire reel to be in automatic winding due to inadvertent or accidental contact with the wire or the wire reel state, and the rolling elastic force of the scroll spring is released for a moment, it is very likely that the product connected by the wire will pop up suddenly and hurt the user, that is, the safety is not high

Embodiment 1

[0037] The wireless winding device of the present invention, such as Figure 1-12 As shown, it includes an upper cover 1, a lower cover 2, a turntable 3, and a scroll spring 4. The upper cover 1 and the lower cover 2 are interlocked with each other. The center of the lower cover 2 protrudes upwards to form a shaft 21. A through hole 31 matching the shaft 21 is opened in the center, and the through hole 31 is sleeved on the shaft 21, so that the turntable 3 is rotatably installed between the upper cover 1 and the lower cover 2, and the turntable 3 is sequentially provided with bottom layers from bottom to top. 32, the middle layer and the top layer 34, the top of the top layer 34 protrudes upwards to form a raised block 341 for clamping the scroll spring 4 (because the structure of the scroll spring 4 clamped on the turntable 3 belongs to the prior art, so it will not be described here. Describe in detail); wherein, the middle layer is a ring-shaped distribution disc 33, and th...

Embodiment 2

[0054] Such as Figure 15 As shown, Embodiment 2 of the wireless cord winding device of the present invention, the difference between this embodiment and the wireless cord winding device of Embodiment 1 is that the structure of the safety switch 9 is different, and the wireless cord winding device of this embodiment The safety switch 9 includes a "U"-shaped catch 921 and a push-pull part 923 for blocking the "U"-shaped movable tenon 6. The "U"-shaped catch 921 is connected with the push-pull part 923 through a connecting rod 922, and the "U"-shaped The catch 921 is located inside the lower cover 2, and the push-pull part 923 is located outside the lower cover 2. The lower cover 2 is provided with a hole for the connecting rod 922 to pass through; the push-pull part 923 pushes the "U"-shaped catch 921 to the "U" position. ""-shaped limit groove 22, "U"-shaped catch 921 blocks the "U"-shaped movable tenon 6 and locks the turntable 3, that is, the safety switch 9 is in the closed...

Abstract

The invention relates to the technical field of wire winding and unwinding devices, in particular to a wireless winding device. The wireless winding device comprises an upper cover, a lower cover, a turntable and a volute spiral spring, wherein the turntable is provided with a bottom layer, a middle layer and a top layer in sequence from bottom to top; the middle layer is an annular wire splitting plate; a wire hooking groove is formed in the annular wire splitting plate; a U-shaped movable mortise and tenon for locating is arranged between the bottom layer and the lower cover; a plane track is formed in the bottom of the bottom layer; and the wireless winding device further comprises a safety switch for manually locking the turntable. During use, the wireless winding device provided by the invention can be applied to and matched with various wire products; moreover, through the adoption of the safety switch of the wireless winding device provided by the invention, the turntable can be manually locked; and as the turntable can rotate as long as a user manually turns on the safety switch, the wireless winding device provided by the invention has the advantage of high safety. In addition, the invention further provides a single-pull winder and a double-pull winder.

Description

technical field [0001] The invention relates to the technical field of wire winding and unwinding devices, in particular to a wireless wire winding device and a single-pull wire reel and a double-pull wire reel using the same. Background technique [0002] As we all know, wired earphones, mice, keyboards, chargers and other products must obtain information, transmit information or supply power through data transmission cables and other wires, or key rings, stationery, accessories, etc. can be retracted by connecting simple wires. In the early days, the above-mentioned wires were usually collected in coils or irregularly. However, the wires were often messy and entangled with each other, which made it difficult to use. Therefore, many designers successively worked on the collection and release of such wires. In terms of function, quite a lot of structures and products have been designed; this kind of product is mainly based on a scroll spring, and the rolling elastic force of...
