DETAILED DESCRIPTION

[0022] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0023] This embodiment, refer to Figures 1-7 The specific implementation of a telescopic data line with self-locking function includes line body 1, shell 2 and winding block 3, winding block 3 is rotatably installed in shell 2 by clockwork 4, line body 1 is wound and arranged on winding block 3, shell 2 is provided with reciprocating sliding sliding piece 5, winding block 3 is provided with self-locking groove 6 matched with sliding piece 5, both ends of line body 1 are provided with magnetic suction head 7, the outside of shell 2 is provided with containing cavity 8, containing cavity 8 is provided with magnetic suction charging port 9 matched with magnetic suction head 7, containing groove is provided with magnetic suction piece for fixing magnetic suction charging port 9, one side of containing cavity 8 is provided with slidable cover 10. By replacing different magnetic suction charging ports 9 to adapt to the charging interface of different equipment, both ends of clockwork 4 are fixed on shell 2 and winding block 3 respectively, through the cooperation of clockwork 4, shell 2 and winding block 3, the function of automatic contraction of line body 1 is realized.

[0024] The shell 2 adopts the upper cover and the lower cover that can be combined, so that the maintenance and replacement of the internal components are more convenient. The upper cover and the lower cover are fixed by thread connection, which ensures the sealing performance of the shell and the stability of the whole. The self-locking groove 6 includes the first recess 11, the second recess 12 and the third recess 13, both ends of the first recess 11 are communicated with the second recess 12, the second recess 12 and the third recess 13 are provided with the connecting part 14 connected with the first recess 11, one end of the second recess 12 is provided with the self-locking wall 15 communicated with the third recess 13. One side of the third recess 13 is provided with the guide part 16.

[0025] When the wire body 1 is fully retracted, the sliding piece 5 stays in the third groove 13. Once the wire body 1 is pulled, the sliding piece 5 starts to move along the track of the self-locking groove 6 with the rotation of the winding block 3. Under the guidance of the guide part 16, the steel ball slides to the first groove 11 through the connecting part 14 of the third groove 13. Since the two ends of the first groove 11 are connected with the second groove 12, the steel ball can move back and forth between the first groove 11 and the second groove 12. When the wire body 1 is released, the elastic force of the spring 4 drives the winding block 3 to rotate in the opposite direction, so that the steel ball contacts the self-locking wall 15 at one end of the second groove 12, thereby realizing the self-locking effect, fixing the winding block 3, and preventing the wire body 1 from retracting by itself. When it is necessary to retract the wire, the wire body 1 is pulled slightly, the sliding piece 5 is separated from the self-locking wall 15, the steel ball slides into the third groove 13, and then continuously slides along the third groove 13 with the reverse rotation of the winding block 3, until the wire body 1 is fully retracted into the shell 2.

[0026] In addition, the depths of the first groove 11, the second groove 12 and the third groove 13 increase in turn. The first groove 11, the second groove 12 and the third groove 13 form steps, and the connecting part 14 is designed as an inclined surface to ensure smooth movement of the steel ball between the grooves. The stepped design enables the steel ball to quickly fall onto the self-locking wall 15 after the winding block 3 is reversed, thereby shortening the distance required for self-locking and improving the self-locking efficiency.

[0027] The shell 2 is provided with a sliding groove 17 cooperating with the sliding piece 5. The length of the sliding groove 17 is greater than the maximum size of the first groove 11 to the third groove 13, ensuring that the sliding piece 5 can slide back and forth along the self-locking groove 6. The sliding piece 5 can be a ball or a round shaft cooperating with the sliding groove 17. The width of the sliding piece 5 is less than the width of the sliding groove 17, so as to ensure that the sliding piece 5 has sufficient space to move in the sliding groove 17, and at the same time prevent it from being stuck or deviating from the track during high-speed movement.

[0028] The shell 2 is provided with a limiting groove 18 cooperating with the cover 10, and the cover 10 is provided with limiting blocks 19 cooperating with the limiting groove 18 on both sides. The cooperation of the limiting groove 18 and the limiting block 19 makes the connection of the shell 2 and the cover 10 more stable, and the cover 10 can only be opened and closed in one direction, effectively preventing the cover 10 from accidentally separating from the shell 2, thereby preventing the magnetic charging port 9 from being lost and other situations from occurring.

[0029] The winding block 3 is provided with clamping grooves 20 cooperating with the wire body 1 on both sides. The clamping grooves 20 on both sides are staggered with each other. The design of the clamping grooves 20 enables the wire body 1 to be evenly distributed during winding, avoiding uneven accumulation of the wire body 1 on the winding block 3, which may cause the wire body 1 to be wound and affect normal use.

[0030] The utility model discloses beneficial effect: through the cooperation of spring 4, sliding piece 5 and self -locking groove 6, realize the self -locking function of line body 1, avoid the retraction of line body 1 in the use process, when taking up the line, just need to pull line body 1 again, can easily complete the winding, thereby improve the convenience of use.

[0031] The above is only the preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model discloses the above preferred embodiment, it is not intended to limit the utility model. Any skilled person in the art can make some changes or modifications to the disclosed technology within the scope of the utility model technical scheme to obtain equivalent embodiments. Any simple modification, equivalent change and modification of the above embodiment within the scope of the utility model technical scheme are all within the scope of the utility model technical scheme.
