[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-6 The data transmission device for preventing leakage and interference shown in the figure comprises a data line 1, a storage shell 2 is movably sleeved on the outside of the data line 1, and a rotating rod 3 is rotatably connected to the inside of the storage shell 2, and the outer wall of the rotating rod 3 is fixedly connected to the middle position of the data line 1, the rotating rod 3 passes through the through hole 5 reserved at the top of the storage shell 2, and the top of the rotating rod 3 is fixedly connected to a rotating plate 4, and the rotating plate 4 is located outside the storage shell 2, and also comprises:

[0029] The limiting component 6 has a movable groove 61 reserved inside the storage shell 2, and the movable groove 61 is movably connected to a movable block 62 through a spring 63, and the end of the movable block 62 is fixedly connected to a sharp corner 64, which matches the slot 65, and the slot 65 is located inside the rotating rod 3.

[0030] The two ends of the data cable 1 are fixedly connected with connector ends 11, and the sizes of the connector ends 11 are different, and the two connector ends 11 can be snapped into the grooves on both sides of the storage shell 2, so that the two connector ends 11 can match with the two openings of the storage shell 2 to store the entire data cable 1.

[0031] Abutment blocks 21 are fixedly connected to both side walls of one end of the storage shell 2, and the outer wall of the abutment block 21 fits with the outer wall of the smaller connector end 11 of the data cable 1 to ensure that the smaller connector end 11 of the data cable 1 will not fall off the storage shell 2.

[0032] There are two movable grooves 61 , and the two movable grooves 61 are symmetrically arranged with reference to the central axis of the through hole 5 as the symmetry axis, and the two movable grooves 61 are connected to the through hole 5 to facilitate the movement of the movable block 62 .

[0033] There are two movable blocks 62, and the two movable blocks 62 are symmetrically arranged with reference to the central axis of the through hole 5 as the symmetry axis, and the two ends of the two movable blocks 62 that are far away are both "T" shaped, and the "T" shaped ends of the movable blocks 62 are always located inside the movable groove 61, ensuring that the movable blocks 62 will not be separated from the inside of the storage shell 2;

[0034] One end of the movable block 62 close to the rotating rod 3 is arc-shaped, and the arc-shaped end wall of the movable block 62 fits with the outer wall of the rotating rod 3, and the outer wall of the arc-shaped end of the movable block 62 is fixedly connected with three sharp corners 64 set at equal angles, and the sharp corners 64 match the slots 65 reserved inside the rotating rod 3, so as to facilitate the position limitation of the rotating rod 3.

[0035] One end of the spring 63 is fixedly connected to the "T"-shaped end of the movable block 62, and the other end of the spring 63 is fixedly connected to the inner wall of the movable groove 61. The spring 63 applies force to push the fixed sharp corner 64 at the end of the movable block 62 to tightly match the slot 65 to ensure the limiting of the rotating rod 3.

[0036] There are a plurality of slots 65, and the slots 65 are arranged in a circular shape at equal angles inside the rotating rod 3. An arc surface 66 is provided at the edge of the slot 65. In this way, when the rotating rod 3 rotates, the inclined inner wall of the slot 65 reserved inside the rotating rod 3 abuts against the outer wall of the sharp corner 64 reserved at the end of the movable block 62, thereby facilitating the movement of the movable block 62. At the same time, the arc surface 66 at the slot of the slot 65 makes it easier for the sharp corner 64 to detach from the slot 65.

[0037] Working principle: When using a data transmission device that prevents leakage and interference, first when the loose data line 1 needs to be stored, the rotating plate 4 is rotated to drive the rotating rod 3 fixedly connected to the end wall of the rotating plate 4 to rotate. During the rotation of the rotating rod 3, the inclined inner wall of the card slot 65 reserved inside the rotating rod 3 abuts against the outer wall of the sharp corner 64 reserved at the end of the movable block 62. As the rotating rod 3 rotates, the movable block 62 is pushed toward the inside of the movable slot 61. After rotating the rotating rod 3 a certain number of times, the data line 1 is unwound to an appropriate length. At this time, the rotating rod 3 is no longer rotated, and the spring 63 pushes the movable block 62 to move. The movable block 62 moves, and the sharp corner 64 reserved at the end of the movable block 62 matches the slot 65 reserved inside the rotating rod 3 at the corresponding position, thereby completing the limitation of the rotating rod 3, so that the overall unwinding length of the data cable 1 is fixed, which is convenient for the use of the entire data cable 1, and at the same time, the rotating rod 3 is rotated in the opposite direction. Similarly, the above operation steps are used to rotate the rotating rod 3 to wind up the data cable 1 fixed to the outer wall of the rotating rod 3, so that the connector ends 11 at both ends of the data cable 1 move and shrink synchronously into the storage shell 2, so that the storage shell 2 can conveniently store the entire data cable 1, so that the data cable 1 is easy to carry.

[0038] At the same time, during the rotation of the rotating rod 3, the slot 65 is reserved inside the rotating rod 3. When the rotating rod 3 needs to be positioned later, the spring 63 pushes the sharp corner 64 of the movable block 62 to match the slot 65 at the corresponding position, thereby ensuring that the data cable 1 will not be loose after being stored, and facilitating the subsequent unfolding and use of the data cable 1.

[0039] The data line's own high-efficiency anti-interference and stable transmission characteristics ensure the security of data transmission.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
