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 volute spring 4. The upper cover 1 and the lower cover 2 are buckled with each other, and the center of the lower cover 2 is formed with a shaft 21 protruding upward. A through hole 31 matching the shaft 21 is opened in the center. The through hole 31 is sleeved on the shaft 21 so that the turntable 3 can be rotatably installed between the upper cover 1 and the lower cover 2. The turntable 3 is provided with a bottom layer from bottom to top. 32. The middle layer and the top layer 34, the top of the top layer 34 protrudes upward and is formed with a bump 341 for clamping the scroll spring 4 (because the structure of the scroll spring 4 to be clamped to the turntable 3 belongs to the prior art, it is not made here Detailed description); Among them, the middle layer is a ring-shaped wire distribution plate 33, the wire dist...

Embodiment 2

[0054] Such as Figure 15 As shown, the second embodiment of the wireless cord reel of the present invention is different from the wireless cord reel of the first embodiment in that the structure of the safety switch 9 is different. The safety switch 9 includes a "U"-shaped latch 921 for clamping the "U"-shaped movable latch 6 and a push-pull portion 923. The "U"-shaped latch 921 is connected to the push-pull portion 923 by a connecting rod 922, and the "U"-shaped The latch 921 is located in the lower cover 2, the push-pull portion 923 is located outside the lower cover 2, and the lower cover 2 is provided with a hole for the connecting rod 922 to pass through; the push-pull portion 923 pushes the "U"-shaped latch 921 to be placed in the "U" ”-Shaped limit slot 22, the “U”-shaped latch 921 clamps the “U”-shaped movable latch 6 and locks the turntable 3, that is, the safety switch 9 is in the closed state; When 921 is pulled out from the "U"-shaped limit slot 22, that is, the sa...

Abstract

The invention relates to the technical field of wire coiling and unwinding devices, in particular to a wireless coiling device, which includes an upper cover, a lower cover, a turntable, and a scroll spring. Ring-shaped cable distribution tray, the cable distribution tray is provided with hooking slots; a "U"-shaped movable tenon for positioning is provided between the bottom layer and the lower cover, and a flat track is provided at the bottom of the bottom layer, and a wireless winding device Also included is a safety switch for manually locking the turntable. When in use, the wireless wire winding device of the present invention can be applied and matched with various wire products; moreover, the safety switch of the wireless wire winding device of the present invention can manually lock the turntable, and only when the user manually turns on the safety switch can it be used The turntable rotates, so the wireless winding device of the present invention has the characteristics of high safety. In addition, the present invention also provides a single cord reel and a double cord reel.

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...
