[0001] The utility model relates to the technical field of data cable storage, in particular to a retractable data cable. Background Art

[0002] A retractable data cable is a portable and easy-to-carry data cable design. Such data cables can usually be stretched or extended to different lengths for convenient use in different situations. These data cables are typically used to connect mobile devices (such as mobile phones, tablets) to computers, chargers, or other compatible devices for data transfer or charging. They usually adopt a design where one end is connected to the device and the other end is connected to a power source or a data interface.

[0003] In a common data cable storage device, the stretching of the data cable is controlled by a coil spring, but there is a lack of a mechanism for limiting the position at any time. It is necessary to stretch it in place before it can be fixed. And when rewinding, the data cable is usually directly stored inside the device and cannot quantitatively recover a certain length. Therefore, a retractable data cable is needed to solve the existing deficiencies. Summary of the Utility Model

[0014] Compared with the prior art, the retractable data cable has the following advantageous effects:

[0015] First, through the one-way mechanism provided in the present invention, at this time, due to the cooperation of the ratchet pawl and the ratchet wheel, under the action of the compression spring, the ratchet wheel cannot rotate in the reverse direction. And by rotating the adjusting block inside the receiving groove, the restriction of the ratchet pawl on the ratchet wheel is released, and the ratchet wheel can be rotated in a reverse direction to wind the connecting wire into the receiving box, which is convenient for protecting the connecting wire and is beneficial to preventing the connecting wire from being retracted during use and maintaining the current length.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] As Figures 1-4 shown, the present utility model provides a technical solution: a retractable data cable, including a receiving box 1, the inside of the receiving box 1 is movably connected with a connecting wire 2, both ends of the connecting wire 2 are located outside the receiving box 1, the inside of the receiving box 1 is movably connected with a winding column 3, the connecting wire 2 is wound around the outside of the winding column 3, a partition 4 is fixedly connected inside the receiving box 1, the top end of the winding column 3 penetrates through the center of the partition 4, and the winding column 3 is movably connected with the partition 4, a one-way mechanism 5 is fixedly connected inside the receiving box 1, and the bottom end of the one-way mechanism 5 is fixedly connected with the top end of the winding column 3, a reset mechanism 6 is fixedly connected inside the receiving box 1, and the reset mechanism 6 is movably connected with the bottom end of the one-way mechanism 5.

[0025] First, pull the connection line 2 outwards, driving the winding column 3 inside the accommodation box 1 to rotate rapidly. Under the action of the speed change box 502, the rotating column 501 rotates slowly, thereby driving the ratchet wheel 503 to rotate. In this way, the connection line 2 gradually elongates until the required length. Stop pulling. At this time, due to the cooperation of the pawl 504 and the ratchet wheel 503, under the action of the compression spring 505, the ratchet wheel 503 cannot rotate in the reverse direction. And by rotating the adjustment block 8 inside the accommodation groove 7, the restriction of the pawl 504 on the ratchet wheel 503 is released, and the ratchet wheel 503 can rotate in the reverse direction, so as to store the connection line 2 inside the accommodation box 1, which is convenient for protecting the connection line 2 and is beneficial to the connection line 2 being unable to be recycled during use and maintaining the current length; during the rotation of the rotating column 501, the driving rod 605 is driven to rotate synchronously, thereby driving the fixed rod to move along the annular groove 9, making the push ring 603 move along the moving ring 601, stretching the return spring 604 to become longer. When the restriction of the pawl 504 on the ratchet wheel 503 is released, under the action of the return spring 604, the push ring 603 is reset, so that the rotating column 501 rotates in the reverse direction, so that the winding column 3 rotates in the reverse direction, thereby storing the connection line 2 inside the accommodation box 1 and preventing the connection line 2 from being worn when exposed to the external environment.

[0026] As Figure 1 , Figure 2 and Figure 4 shown, the one-way mechanism 5 includes a rotating column 501, a speed change box 502, a ratchet wheel 503 and a pawl 504. The pawl 504 is movably connected to the inside of the accommodation box 1 through a rotating shaft. The ratchet wheel 503 is movably connected to the inside of the accommodation box 1 through the rotating column 501, and the pawl 504 meshes with the ratchet wheel 503. The bottom end of the rotating column 501 is fixedly connected to the output end of the speed change box 502, and the top end of the winding column 3 is fixedly connected to the input end of the speed change box 502. The one-way mechanism 5 further includes a compression spring 505. One end of the compression spring 505 is fixedly connected to the inside of the accommodation box 1, and the other end of the compression spring 505 is fixedly connected to the back side of the pawl 504. An accommodation groove 7 is opened at the top end of the accommodation box 1, and an adjustment block 8 is movably connected to the inside of the accommodation groove 7. The adjustment block 8 is fixedly connected to the top end of the rotating shaft of the pawl 504.

[0027] First, pull the connecting line 2 outwards, driving the winding column 3 inside the accommodating box 1 to rotate rapidly. Under the action of the speed change box 502, the rotating column 501 rotates slowly, thereby driving the ratchet wheel 503 to rotate. In this way, the connecting line 2 gradually elongates until the required length. Stop pulling. At this time, due to the cooperation of the pawl 504 and the ratchet wheel 503, under the action of the compression spring 505, the ratchet wheel 503 cannot rotate in the reverse direction. And by rotating the adjusting block 8 inside the accommodating groove 7, the restriction of the pawl 504 on the ratchet wheel 503 is released, and the ratchet wheel 503 can rotate in the reverse direction, thereby storing the connecting line 2 into the inside of the accommodating box 1, which is convenient for protecting the connecting line 2 and is beneficial to preventing the connecting line 2 from being retractable during use and maintaining the current length.

[0028] As Figures 1-3 shown, the reset mechanism 6 includes a moving ring 601, a support block 602, a pushing ring 603 and a reset spring 604. The moving ring 601 penetrates the support block 602, and the moving ring 601 is fixedly connected to the support block 602. The moving ring 601 is fixedly connected to the inside of the accommodating box 1 through the support block 602. The moving ring 601 penetrates the pushing ring 603, and the moving ring 601 is movably connected to the pushing ring 603. The reset spring 604 is sleeved on the outside of the moving ring 601. The reset mechanism 6 includes a driving rod 605 and a fixed column 606. One end of the driving rod 605 is fixedly connected to the outer side of the bottom end of the rotating column 501. The top end of the fixed column 606 is fixedly connected to the bottom end of the pushing ring 603, and the bottom end of the fixed column 606 penetrates the other end of the driving rod 605. The fixed column 606 is movably connected to the driving rod 605. The reset spring 604 is arc-shaped. One end of the reset spring 604 is fixedly connected to the support block 602, and the other end of the reset spring 604 is fixedly connected to the pushing ring 603. A ring groove 9 is opened at the top end of the partition plate 4. The bottom end of the fixed column 606 is movably connected to the inside of the ring groove 9.

[0029] During the rotation of the rotating column 501, the driving rod 605 is driven to rotate synchronously, thereby driving the fixed rod to move along the ring groove 9, causing the pushing ring 603 to move along the moving ring 601, stretching the reset spring 604 to become longer. When the restriction of the pawl 504 on the ratchet wheel 503 is released, under the action of the reset spring 604, the pushing ring 603 is reset, thereby causing the rotating column 501 to rotate in the reverse direction, so that the winding column 3 rotates in the reverse direction, thereby facilitating the storage of the connecting line 2 into the inside of the accommodating box 1 and preventing the connecting line 2 from being exposed to the external environment and being worn.

[0030] Working principle: When in use, first, pull the connecting line 2 outwards, driving the winding column 3 inside the accommodating box 1 to rotate rapidly. Under the action of the speed change box 502, the rotating column 501 rotates slowly, thereby driving the ratchet wheel 503 to rotate. In this way, the connecting line 2 gradually elongates until the required length. Stop pulling. At this time, due to the cooperation of the pawl 504 and the ratchet wheel 503, under the action of the compression spring 505, the ratchet wheel 503 cannot rotate in the reverse direction. And by rotating the adjusting block 8 inside the accommodating groove 7, the restriction of the pawl 504 on the ratchet wheel 503 is released, and the ratchet wheel 503 can rotate in the reverse direction, thereby storing the connecting line 2 into the inside of the accommodating box 1; during the rotation of the rotating column 501, the driving rod 605 is driven to rotate synchronously, thereby driving the fixed rod to move along the annular groove 9, making the push ring 603 move along the moving ring 601, stretching the return spring 604. When the restriction of the pawl 504 on the ratchet wheel 503 is released, under the action of the return spring 604, the push ring 603 is reset, thereby making the rotating column 501 rotate in the reverse direction, so that the winding column 3 rotates in the reverse direction, thereby storing the connecting line 2 into the inside of the accommodating box 1.
