[0017] like Figure 1 As shown, this utility model is a data cable reel that produces a hissing sound during cable unwinding and rewinding.

[0018] like Figure 1 , 2 As shown in Figures 3 and 6, a data cable reel that produces a hissing sound during cable unwinding and rewinding includes a housing 1, a cable unwinding / rewinding mechanism 2, a circuit switching mechanism 3, a tooth-shifting mechanism 4, and a control mechanism 5.

[0019] To control the length of cable retraction and delivery according to user needs, the housing 1 includes a bottom shell 11 and a top shell 12 that engages with the bottom shell 11. The inner side of the top shell 12 is provided with a dial mounting position 124 and a control component mounting position 125. The dial mounting position 124 is provided with an embedded protrusion 127, and the control component mounting position 125 is provided with a rotating shaft 126. One side of the top shell 12 is provided with a power data cable inlet 121 for installing a power data cable interface. The center of the top shell 12 is provided with an assembly hole 122, and the periphery of the assembly hole 122 is provided with a first circuit board mounting position 123 for assembly with the bottom shell 11 by screws. The center of the inner side of the bottom shell 11 is provided with a central shaft 111.

[0020] In order to improve the power of the take-up and unwinding mechanism and effectively manage the retrieved wire, the take-up and unwinding mechanism 2 includes a turntable 20, a take-up groove 25 at the bottom of the turntable 20, a spring chamber 24 at the center of the take-up groove 25, a second circuit board mounting position 22 at the middle of the top surface of the turntable 20, a track 21 around the second circuit board mounting position 22, a spring 26 installed in the spring chamber 24, and a data telescopic cable 27 stored in the take-up groove 25.

[0021] In order to enable the coiler to be used on devices with larger current and larger data transmission volumes, the circuit conversion mechanism 3 includes a first circuit board 31 installed inside the top shell, a second circuit board 32 installed in the middle of the turntable 20, and a contact terminal 33 installed at the front end of the second circuit board 32. The contact terminal 33 slides in the closed annular circuit 35 of the first circuit board 31 and is used to connect the fixed terminal 34 to the data retractable cable 27 by rotation.

[0022] In order to produce a rhythmic and melodic creaking sound during line release and reeling, the tooth-shifting mechanism 4 includes a toothed head 41 and toothed teeth 23. The toothed head 41 is embedded inside the top shell, and the toothed teeth 23 are arranged on the periphery of the track 21 and are evenly distributed in a gear shape.

[0023] To allow users to control the length of the data telescopic cable 27 according to their needs, the control mechanism 5 includes a control component 53 and a track 21. One end of the control component 53 is provided with a sliding shaft 52, and the other end is provided with a shaft hole 51. The sliding shaft 52 slides in the track 21 as the turntable 20 rotates. The control component 53 is rotatably mounted on the rotating shaft 126 through the shaft hole 51. The dial 41 is embedded in the mounting protrusion 127. One end of the first circuit board 31 is provided with a terminal 34, and the other end is provided with a closed circular circuit 35.

[0024] like Figure 3 and 6 As shown, in order to simplify the structure of the reel and save the use of a return spring, the dial head 41 is made of an elastic material (e.g., rubber, plastic, etc.). As the turntable 20 rotates, the dial head 41 will bend to the left or right once under the push of the pulling force when passing through a tooth 23. Then, it will quickly return to its original position under the action of its own elasticity and slide into the next tooth 23, making a "snap" sound when it hits the next tooth 23. The same sound will be made when passing through a tooth 23. Under the plucking of the tooth 23, the dial head 41 can bend to the left or right due to its elasticity. When the tooth 23 stops plucking, the dial head 41 will automatically return to the center by its own elasticity.

[0025] like Figure 6 As shown, the turntable 20 is rotatably mounted on the central shaft 111 on one side of the inner bottom shell of the housing 1. When the data retractable cable 27 is pulled out, the turntable 20 rotates clockwise, which in turn drives the dial tooth 23 to rotate clockwise. Under the continuous collision between the dial head 41 and the dial tooth 23, a "snip" sound is emitted. This "snip" sound is not only a sign that the data cable is pulled out and retracted, but also a working mode of the cable retractor.

[0026] like Figure 2 and 6 As shown, in order to ensure that the contact terminal 33 can maintain continuous sliding contact with the closed ring circuit 35, there are two contact terminals 33. Each contact terminal 33 is electrically connected to the second circuit board 32. The second circuit board 32 is electrically connected to the inner end of the data telescopic cable 27. The wiring terminal 34 passes through the top of the top shell 12 and is electrically connected to the power supply and the data source. The two contact terminals 33 are covered with a first circuit board 31. The closed ring circuit 35 is in corresponding contact with the contact terminal 33. As the turntable 20 rotates, each contact terminal 33 slides in a circle corresponding to and closely attached to a closed ring circuit 35, transmitting the current and data information from the first circuit board 31 to the second circuit board 32.

[0027] like Figure 4 and 6As shown, the inner end of the spring 26 is fixed to the central shaft 111, and its outer end is fixed to the turntable 20. When the data extension cable 27 is pulled, the turntable 20 rotates accordingly, and the spring 26 tightens to generate potential energy, providing power for the turntable to retract.

[0028] like Figure 5 and 6 As shown, as the track 21 bends and deforms, the slide shaft 52 drives the control component 53 to swing back and forth around the rotating shaft 126, constantly adjusting the position of the slide shaft 52 in the track. Combined with the special structure of the track 21, it controls the forward, reverse and stop motion of the turntable 20.

[0029] like Figure 2 and 6 As shown, in order to control the rotation of the turntable 20, the track 21 is divided into a pay-off track 211 and a take-up track 212. The pay-off track 211 is located on the outer ring of the track 21, and the take-up track 212 is located on the inner ring of the track 21. A track switching port 213 is provided between the pay-off track 211 and the take-up track 212. When pay-off, the sliding shaft 52 slides clockwise in the pay-off track 211. When take-up, the sliding shaft 52 enters the take-up track 212 through the track switching port 213 and slides counterclockwise. When the sliding shaft 52 slides counterclockwise in the pay-off track 211, it will automatically fall into the track switching port 213 and be locked. When it is pulled out again, it slides into the take-up track 212. When the sliding shaft 52 slides clockwise in the take-up track 212, it will automatically pass through the track switching port 213 and enter the pay-off track 211.

[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
