For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The utility model provides a retractable data cable that slows down the speed of cable recovery. As shown in Figure 1, it includes a housing 1, a cable 2, a winding component 3 for driving the movement of the cable 2, a movable component 4 and Limiting component 5. The winding component 3, the movable component 4 and the limiting component 5 are all arranged in the housing 1. After the cable 2 is wound around the winding component 3, both ends are exposed to the housing 1.

The reel assembly 3 includes a reel 31, which can rotate relative to the housing 1. The movable component 4 is arranged on one side of the reel 31. The movable component 4 moves with the rotation of the reel 31. The movable component 4 is used for This is used to lock the cable reel 31 when the cable reel 31 stops rotating, and to cooperate with the cable reel 31 to retract the cable 2 .

The limiting component 5 is used to slow down the speed of the cable 2 when it is recovered. In a specific embodiment, the limiting component 5 includes at least one protrusion 51 provided on the inner wall of the housing 1 , and one end of the protrusion 51 is in sliding contact with the cable 2 . When the cable 2 is retracted, it will come into sliding contact with the protrusion 51 to generate friction, thereby decelerating the cable. Inevitably, when the cable 2 is stretched outward, it will also rub against the protrusion 51 and decelerate.

It should be noted that when the cable 2 is stretched and retracted, only a section of the cable 2 near both ends will come into sliding contact with the protrusion 51 . The reason is that when the cable 2 is completely wound on the reel 31, the cable 2 is larger in size and the cable 2 located in the outer ring can contact the protrusion 51. When the cable 2 is stretched outward for a certain distance, the cable 2 is rolled up. The volume of the cable 2 on the cable drum 31 becomes smaller, and the cable 2 can no longer contact the protrusion 51 . The opposite is true when recycling.

When the utility model is used, the cable 2 is stretched outward, the cable 2 will drive the reel 31 to rotate, and the rotation of the reel 31 will drive the movable component 4 to move. When the cable 2 is stretched to any length and then stops, the movable component 4 can lock the reel 31 so that the cable 2 stays at the current length. When the cable 2 is to be retracted, the cable 2 is stretched outward a short distance. At this time, the blocking state of the cable reel 31 and the movable component 4 disappears, and the cable 2 is retracted as the cable reel 31 rotates. During the retrieval process, the cable 2 will come into sliding contact with the protrusion 51 to generate friction, which will slow down the retrieval speed, thus preventing the cable 2 from being damaged due to excessive speed during retrieval and the high-speed collision of the cable 2 with the outlet of the housing 1. The problem.

Further, in a specific embodiment, the protrusion 51 includes a first contact portion 511 and a second contact portion 512 with different curvatures. The curvature of the second contact portion 512 is greater than that of the first contact portion 511 . The first contact portion 511 is located on the target. On the first side of the axial surface 514 , the second contact portion 512 is located on the second side of the target axial surface 514 . Specifically, referring to Figures 2 and 3, the projection of the target axial surface 514 in the thickness direction of the housing 1 passes through the highest convex point of the protrusion 51 and passes through the connection surface between the protrusion 51 and the inner wall of the housing 1. The first end of the target axial surface 514 The second side of the target axis surface 514 faces the retracting rotation direction of the cable 2 , and the second side of the target axis surface 514 faces away from the retracting direction of the cable 2 . It can be understood that the curvature of the second contact part 512 is larger, so that the friction force with the cable 2 is increased, and the deceleration effect of the recovery of the cable 2 is better; the curvature of the first contact part 511 is smaller, so that the friction force is smaller. Small, convenient for cable 2 to stretch outward. The above terms of large curvature and small curvature are relative terms and are not used to describe the specific size of curvature.

In a specific embodiment, as shown in FIG. 4 , the surface of the protrusion 51 further includes at least one damping portion 513 . The damping portion 513 is used to increase the friction coefficient between the protrusion 51 and the cable 2 to achieve a better deceleration effect. Preferably, the damping portion 513 is provided on the second contact portion 512, which causes the cable 2 to experience greater friction when being recovered, thereby improving the deceleration effect. The structure of the damping part 513 is not limited to the structure shown in FIG. 3 .

In a specific embodiment, as shown in Figure 3, a wear-resistant layer 21 is provided on the outside of the cable 2. The wear-resistant layer 21 is the part where the cable 2 is in sliding contact with the protrusion 51 to prevent the cable 2 from being in contact with the protrusion 51 for a long time. The protrusions 51 are damaged by friction, which improves the durability of the cable 2 . Optionally, the wear-resistant layer 21 is made of a wear-resistant material. Preferably, the material of the wear-resistant layer 21 is polyoxymethylene. On the other hand, the wear-resistant layer 21 can be provided only on the outer cable 2, that is, only on a section of the cable 2 that is in sliding contact with the protrusion 51, which can make the cost lower.

In a specific embodiment, as shown in FIG. 5 , the surface of the cable 2 is also provided with anti-skid patterns 22 . The anti-skid patterns 22 are used to increase the friction coefficient between the protrusions 51 and the cable 2 so as to achieve a better deceleration effect. Preferably, the anti-skid pattern 22 is only provided at the portion where the cable 2 is in sliding contact with the protrusion 51 . The style of the anti-skid pattern 22 is not limited to Figure 4 .

In a specific embodiment, referring to FIGS. 1 and 6 to 10 , the movable assembly 4 includes a transmission gear 41 connected to the reel 31 , a swing member 42 , a limiting gear 43 and an auxiliary member 44 .

Specifically, the swing member 42 , the limiting gear 43 and the auxiliary member 44 are all positioned to connect to the housing 1 . The above-mentioned positioning connection can be understood as the relative positioning between the above-mentioned components and the housing 1, but the components can move in positions relatively positioned with the housing 1. See Figure 5 for details.

Further, as shown in FIGS. 7 to 10 , the swing member 42 includes a first unit 421 that cooperates with the transmission gear 41 for transmission, a second unit group 422 that cooperates with the limiting gear 43 for limiting, and a third unit that cooperates with the auxiliary member 44 . The unit 423, the auxiliary member 44 and the third unit 423 cooperate to provide the swing member 42 with a pre-tightening force toward or away from the auxiliary member 44 side. This pre-tightening force can cause the swing member 42 to have a tendency to swing toward or away from the auxiliary member 44 . The auxiliary member 44 may be a strip-shaped elastic member capable of elastic deformation. The structure is shown in Figure 9 .

Specifically, the cooperation between the first unit 421 and the transmission gear 41 can be understood as the transmission gear 41 is connected to the reel 31 and can rotate with the reel 31. The rotation of the transmission gear 41 will cooperate with the first unit 421 to drive the swing. The swinging member 42 swings, and the swinging member 42 swings and in turn drives the limiting gear 43 and the auxiliary member 44 to move; the second unit group 422 and the limiting gear 43 cooperate to limit the position, which can be understood as stretching the cable 2 outward for a certain distance and then releasing it. Open, the second unit group 422 will be locked with the limiting gear 43, so that the swing member 42 is fixed to the current position, and the first unit 421 of the swing member 42 will be locked with the transmission gear 41, so that the reel 31 is fixed, and then the Cable 2 is fixed to its current position.

Further, referring to FIGS. 7 to 10 , the second unit group 422 includes a first fitting part 4221 and a second fitting part 4222 . The first fitting part 4221 and the second fitting part 4222 are respectively provided at both ends of the swing member 42 . Among them, the first fitting part 4221 is used to push the limiting gear 43 , and the second fitting part 4222 is used to lock the limiting gear 43 . Specifically, the limiting gear 43 includes a first tooth groove 431 and a second tooth groove 432. The first fitting part 4221 cooperates with the first tooth groove 431 to push the limiting gear 43. The second fitting part 4222 cooperates with the second tooth groove. 432 cooperates to lock the limiting gear 43.

Further, as shown in Figure 11, the reel assembly 3 also includes a coil spring 32 and a coil spring fixing part 33. The coil spring fixing part 33 is provided on the side of the reel 31 away from the movable component 4, and the coil spring 32 is connected to the coil spring. Fastener 33.

The principle and beneficial effects of the optimal embodiment of the present invention are as follows: when the cable 2 is stretched in the recovery state, the coil spring fixing member 33 continues to rotate with the reel 31, and the elastic force of the coil spring 32 continues to increase. On the other side, the reel 31 drives the transmission gear 41 to rotate. The transmission gear 41 cooperates with the first unit 421 of the swing member 42 to drive the swing member 42 to swing. The second matching portion 4222 of the swing member 42 cooperates with the first tooth slot 431. The limiting gear 43 is pushed to rotate, and the third unit 423 of the swing member 42 squeezes the elastically deformable auxiliary member 44 to generate a pre-tightening force. After the swing member 42 swings for a certain distance, the first unit 421 will break away from the tooth groove of the transmission gear 41. At this time, under the action of the preload force of the auxiliary member 44, the swing member 42 swings back, and the first unit 421 continues to communicate with the transmission gear 41. The next alveolar fit. When the cable 2 is stretched to a certain position and then let go, the reel 31 rotates under the influence of the elastic force of the coil spring 32, driving the swing member 42 to swing back. The two tooth grooves 432 cooperate with each other to lock, so that the swing member 42 is fixed to the current position. The first unit 421 of the swing member 42 cooperates with the transmission gear 41 to lock the cable reel 31, thereby realizing the locking and fixing of the cable 2.

When recovering the cable 2, the cable 2 needs to be stretched outward for a short distance. At this time, the transmission gear 41 will drive the swing member 42 to swing for a certain distance, so that the first matching part 4221 of the swing member 42 pushes the limiting gear 43, causing the limit gear 43 to move. The second tooth groove 432 of the bit gear 43 moves to the preset position. After letting go, the swinging member 42 swings back, and the second matching portion 4222 of the swinging member 42 cooperates with the second tooth groove 432 of the limiting gear to lock and fix the swinging member 42. At this time, the first unit 421 of the swinging member 42 no longer interacts with the first unit 421 of the swinging member 42. The transmission gear 41 cooperates, and the reel 31 rotates under the influence of the elastic force of the coil spring 32, thereby retracting the cable 2.

During the retrieval process, the cable 2 will not rub against the protrusion 51 at the beginning. When the cable 2 is retracted to a certain extent, it will come into frictional contact with the protrusion 51, thereby slowing down the retrieval speed. The second contact portion 512 of the protrusion 51 is provided with a damping portion 513, and the cable 2 is provided with an anti-skid pattern 22, so that the deceleration effect is better during recovery. The cable 2 is wrapped with a wear-resistant layer 21 to make the cable 2 more durable.
