Description

Technical Field

[0001] This utility model relates to the field of data cable device technology, and in particular to a retractable data cable device with a pressure-reducing effect. Background Technology

[0002] Because ordinary data cables are generally long and inconvenient to carry, various retractable data cables have been invented. These cables use a spring-loaded mechanism within the casing to wind up the cable, achieving a more compact design and preventing tangling. Traditional retractable data cable devices are generally silent and do not provide a stress-relieving effect. Therefore, some retractable data cable devices with stress-relieving effects have been invented, mainly in two ways. One method involves a rotating wheel (similar to a gear) with arc-shaped grooves inside the casing, which works in conjunction with a fixed ball and spring within the casing. When the rotating wheel rotates, the ball, under the spring's force, presses into the arc-shaped grooves in sequence, producing a rhythmic "click, click, click" sound, providing a certain stress-relieving effect. However, this method requires an additional rotating wheel, making the structure more complex. The other method involves arc-shaped grooves on the circumference of the wheel core, which work in conjunction with the fixed ball and spring within the casing. This method requires space around the wheel core to accommodate the ball and spring, resulting in a larger overall diameter, which does not meet the requirements for miniaturization. Furthermore, current structures that use curved grooves in conjunction with marbles to produce sound generally have relatively small grooves; otherwise, the marbles wouldn't make a sound when pressed in. Based on actual usage, smaller grooves (i.e., more densely packed grooves) typically produce a crisper sound, failing to produce a deeper, more resonant sound, thus not satisfying users with other needs. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a pressure-reducing telescopic data cable device that has a simple structure, reasonable design, does not increase the diameter of the device, has a pressure-reducing effect, and can emit a deep sound.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a pressure-reducing telescopic data cable device, comprising a housing, a wheel core, and a sound-generating mechanism. The wheel core is movably installed in the housing to form a rotatable structure for winding the cable. The sound-generating mechanism includes an elastic impact component, which is connected to the wheel core. Several protruding ribs are provided on at least one of the upper and lower surfaces of the wheel core. The elastic impact component is installed inside the housing at a position opposite to the protruding ribs. When the wheel core rotates, the elastic impact component passes over the protruding ribs and impacts the surface of the wheel core to generate sound.

[0005] Furthermore, a ring of wheel core grooves is provided on the surface of the wheel core, and each rib is arranged radially within the wheel core groove in a radial pattern.

[0006] Furthermore, the wheel core groove is located in the area surrounded by the guide groove on the wheel core.

[0007] Furthermore, the elastic impact component includes a ball and a spring. The spring presses the ball against the wheel core, and the ball makes a sound when it hits the wheel core.

[0008] Furthermore, the housing includes a bottom shell and a top shell, with the wheel core installed in the bottom shell and the top shell covering the wheel core and wire.

[0009] Furthermore, the ribs are set on the upper surface of the wheel core, the faceplate covers the upper surface of the wheel core, and the ball and spring are installed on the inner surface of the faceplate.

[0010] Furthermore, a cover ring is provided on the inner surface of the faceplate, and the cover ring is opposite to each of the raised ribs; the cover ring is provided with a mounting hole, and the ball and the spring are installed together in the mounting hole.

[0011] Furthermore, a receiving groove is provided on the surface of the faceplate, and a mounting hole is exposed in the receiving groove for inserting a ball and a spring. A cover is provided on the receiving groove to cover the receiving groove.

[0012] Preferably, the cross-section of the rib is semi-cylindrical, the number of ribs is 3-18, and they are evenly distributed. Each rib is an integral structure with the wheel core.

[0013] This invention features raised ribs on the surface of a wheel core and a combination of a ball and a spring on the housing. When the wheel core rotates, the ball is pressed down by the spring and strikes the wheel core, producing a sound as it rotates past the raised ribs. This design fully utilizes the space between the wheel core surface and the housing to accommodate the ball and spring without increasing the overall size of the device. Furthermore, different sounds can be achieved by varying the density of the raised ribs: denser ribs produce a crisper sound, while sparser ribs produce a deeper sound. This rhythmic and stress-relieving sound provides a better user experience. Attached Figure Description
