Detailed implementation mode

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Refer to Figures 1 to 5 , a retractable data cable, comprising an outer shell 1, a cable 2, a cable reel 3, a resilient member 4 and a first speed reduction assembly 5;

[0029] The outer shell 1 is composed of a first housing 11 and a second housing 12, and a cavity is formed inside. The first housing 11 and the second housing 12 can be assembled by structures such as screws or buckles;

[0030] Refer to Figure 2 , the cable reel 3 is rotatably arranged inside the outer shell 1. The cable reel 3 is provided with a central hole 30, and the second housing 12 is provided with a central axis 120 that cooperates with it;

[0031] Refer to Figure 3 , the cable reel 3 is provided with a cable winding part 31, and the cable 2 can be wound around the outer periphery of the cable winding part 31; the cable winding part 31 includes a first flange 311 and a second flange 312. Both the first flange 311 and the second flange 312 can be arc-shaped and are arranged oppositely. A first notch 31a and a second notch 31b are left between the first flange 311 and the second flange 312;

[0032] The cable reel 3 is further provided with a cable fixing part 32. The cable fixing part 32 is arranged inside the cable winding part 31, for example, inside the first flange 311. The cable fixing part 32 is arc-shaped. The cable fixing part 32 and the first flange 311 form a cable fixing groove 320 that can accommodate part of the cable 2; thus, the middle part of the cable 2 can be placed in the cable fixing groove 320. One end of the cable 2 extends out of the outer shell 1 after passing around the first notch 31a, and the other end of the cable 2 extends out of the outer shell 1 after passing around the second notch 31b;

[0033] Refer to Figure 3, a resilient member 4 is provided on the inner circumference of the wire winding portion 31, that is, the resilient member 4 is provided in the space surrounded by the wire winding portion 31. The resilient member 4 is a spiral spring structure. The fixed end 41 of the resilient member 4 is connected to the central shaft 120. The central shaft 120 is provided with a transverse groove 1201 that cooperates with the fixed end 41. The movable end 42 of the resilient member 4 is connected to the wire winding portion 31 or the wire fixing portion 32, for example, connected to the inner groove 321 of the wire fixing portion 32;

[0034] The cable 2 is pre-wound around the wire spool 3 in a winding manner. When the cable 2 is pulled, the wire spool 3 rotates in the A direction, and the cable 2 is stretched; when winding, the resilient member 4 drives the wire spool 3 to rotate in the B direction, and the cable 2 is retracted back onto the wire spool 3.

[0035] Reference Figure 4 And Figure 5 , the wire winding portion 31 is further provided with a ratchet portion 33. The ratchet portion 33 has gears. The distance between adjacent gears is greater than 1.8 mm and less than 47 mm. Through market research and experimental studies, when the distance between adjacent gears is less than 1.8 mm, the mold accuracy of the wire spool needs to be one or two levels higher, which will seriously increase the cost; when the distance between adjacent gears is greater than 47 mm, there is also a risk of hand injury. Therefore, it is reasonable to set the distance between adjacent gears to be greater than 1.8 mm and less than 47 mm. The gears are helical gears and are evenly distributed on the outer edge of the wire spool 3.

[0036] The ratchet portion 33 can be provided on a side away from the wire winding portion 31. The first deceleration assembly 5 includes a clamping member 51. When the cable 2 is pulled to the required length, the clamping member 51 can clamp the ratchet portion 33 to prevent the wire spool 3 from rotating in the B direction, thereby limiting the rotation of the wire spool 3 and realizing arbitrary and stepless telescopic stretching of the cable 2, which is more convenient to use and has a simple structure.

[0037] The clamping member 51 includes a shaft hole 510, a clamping portion 511 and a triggering portion 512. The housing 1 is provided with a rotating shaft 121 that cooperates with the shaft hole 510; the rotating shaft 121 can be provided in the second housing 12; the clamping portion 511 is connected to the ratchet portion 33, and the triggering portion 512 extends out of the housing 1.

[0038] The first deceleration assembly 5 further includes a first elastic member 52. The first elastic member 52 pushes the clamping member 51 to swing, so that the clamping portion 511 abuts against the ratchet portion 33. The first elastic member 52 can be a spring. The lower end of the first elastic member 52 is connected to the clamping member 51, and the upper end of the first elastic member 52 is connected to the housing 1.

[0039] When the cable 2 is pulled to the required length, the first elastic member 52 pushes the clamping member 51 to clamp the ratchet portion 33, preventing the wire spool 3 from rotating in the B direction, and the cable 2 will not be retracted; when winding is required, the triggering portion 512 is pushed to cause the clamping member 51 to swing away from the ratchet portion 33, and the resilient member 4 drives the wire spool 3 to wind the cable 2.

[0040] Reference Figure 4 With Figure 6 It further includes a second deceleration assembly 6, and the second deceleration assembly 6 can slow down the rotation speed of the wire reel 3. For example, it slows down the rotation speed during winding, reduces or prevents the wire 2 from scratching the hand during winding, or reduces the large accidental contact between the ratchet portion 33 and the clamping member 51.

[0041] The second deceleration assembly 6 includes a friction member 61, and the wire reel 3 is provided with a disk shoulder portion 34 that cooperates with the friction member 61. The disk shoulder portion 34 can be provided on the side of the wire reel 3 away from the winding portion 31, and the diameter of the disk shoulder portion 34 can be larger than the diameter of the ratchet portion 33.

[0042] The friction member 61 includes a friction portion 613, a body 612, and a pressing portion 611;

[0043] The pressing portion 611 is partially disposed outside the housing 1, and the friction portion 613 is disposed inside the housing 1; by pressing the pressing portion 611, the friction portion 613 can be movably abutted against the wire reel 3.

[0044] Specifically, the friction portion 613 can be abutted against the disk shoulder portion 34; the housing 1 is provided with a guiding groove 122 that cooperates with the body 612, and the guiding groove 122 can be provided in the second housing 12.

[0045] Press down the pressing portion 611, the friction portion 613 approaches the disk shoulder portion 34 and contacts the disk shoulder portion 34, thereby forming a certain frictional torque to slow down the rotation speed of the wire reel 3.

[0046] The friction portion 613 is a flexible friction member, such as a flexible rubber member, which can increase the friction force. The friction portion 613 has an abutting surface, and the abutting surface is an inclined surface or an arc surface, and the included angle between the abutting surface and the tangent of the wire reel is not greater than 45°.

[0047] The second deceleration assembly 6 further includes a second elastic member 62, and the second elastic member 62 urges the friction portion 613 to be away from the disk shoulder portion 34 or the wire reel 3, and the second elastic member 62 functions to reset. The second elastic member 62 can be a spring, the lower end of the second elastic member 62 is connected to the housing 1, and the upper end of the second elastic member 62 is connected to the pressing portion 611.

[0048] The above disclosure is only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
