The motor 3 drives the winding drum 2 to rotate, and a transmission belt 5 is arranged between the winding drum 2 and the screw rod 6. The transmission belt 5 can be a transmission belt or a crawler. When the motor 3 starts to drive the winding drum 2 to rotate, the screw rod 6 is also driven to rotate through the transmission belt 5, and the rotation of the screw rod 6 drives the sliding seat 4 to slide back and forth along the axial direction of the winding drum 2.

[0027] See also Figure 6 , wherein the shaft rod 7 is movably arranged on the sliding seat 4 , the shaft rod 7 can rotate on the sliding seat 4 along its axial direction and can slide on the sliding seat 4 along its axial direction, and a gear 20 is coaxially fixedly connected to the shaft rod 7 .

[0028] The driving wheel 8 is connected to the shaft rod 7 by sliding along the axial direction of the shaft rod 7. Specifically, the shaft rod 7 is provided with a groove along its axial direction, and a protrusion is provided on the inner wall of the driving wheel 8. The driving wheel 8 is connected to the shaft rod 7 by sliding along the groove on the shaft rod 7 through the protrusion. The shaft rod 7 rotates along its axial direction to drive the driving wheel 8 to rotate together. The driven wheel 9 is arranged on the sliding seat 4, and the cable is wound between the driven wheel 9 and the driving wheel 8 and connected to the winding drum 2; preferably, the driven wheel 9 is connected to the sliding seat 4 by sliding along the axial direction of the winding drum 2, and the sliding seat 4 is provided with a sliding groove 11 along the axial direction of the winding drum 2, and a sliding rod 10 is slidably connected in the sliding groove 11, and the driven wheel 9 is rotatably connected to the sliding rod 10. One end of the sliding rod 10 is threadedly connected with a first locking nut. The distance between the driving wheel 8 and the driven wheel 9 is changed by moving the sliding rod 10 to adapt to cables of different specifications, and the position of the sliding rod 10 is locked by the first locking nut.

[0029] See also Figure 4 and Figure 5 The first rack 16 and the second rack 17 are both parallel to the axial direction of the take-up drum 2, and are both slidably arranged on the box body 1 along the direction in which the cable enters and exits the box body 1. The tooth surfaces of the first rack 16 and the second rack 17 are arranged facing each other, and the height of the first rack 16 is higher than the height of the second rack 17.

[0030] See also Figure 5, wherein the push-pull member 18 is used to drive the first rack 16 and the second rack 17 to slide synchronously in the opposite direction. Specifically, the push-pull member 18 includes a push-pull rod 1803 and a connecting block 1802. The connecting block 1802 is provided with two groups.

Before automatically winding up the cable, the push-pull member 18 is used to drive the first rack 16 and the second rack 17 to slide synchronously in the opposite direction, so that the gear 20 is not meshed with the first rack 16 and the second rack 17 during the reciprocating sliding of the sliding seat 4, and the winding work is not hindered when winding the cable. Before automatically unfolding the cable, the push-pull member 18 is used to drive the first rack 16 and the second rack 17 to slide synchronously in the opposite direction, so that the sliding seat 4 is meshed with the first rack 16 only through the switching component during the reciprocating sliding outward stroke; the sliding seat 4 is meshed with the second rack 17 only through the switching component during the reciprocating sliding return stroke, so that the sliding seat 4 is reciprocating along the axial direction of the winding drum 2. The gear 20 always drives the shaft rod 7 to rotate along the axial direction of the shaft rod 7 in the same direction during the reciprocating sliding stroke of the winding drum 2, so that the driving wheel 8 on the shaft rod 7 always rotates in the same direction to transport the cable to the outside of the box body 1.

[0031] See also Figure 6 and Figure 7The switching assembly includes a fixed plate 13, a guide groove and a sliding part 12. The fixed plate 13 is fixedly arranged in the box body 1. In the embodiment of the present invention, the fixed plate 13 is symmetrically arranged on both sides of the shaft rod 7 along the cable inlet and outlet direction. The guide groove is arranged on the fixed plate 13, which includes a first horizontal groove 14 and a special-shaped groove 15. The first horizontal groove 14 includes a first groove section 1401, a second groove section 1402 and a third groove section 1403 connected in sequence. The special-shaped groove 15 includes a second horizontal groove 1502. One end of the second horizontal groove 1502 is connected to the junction of the first groove section 1401 and the second groove section 1402 through the first inclined groove 1501, and the other end is connected to the second groove section 140 through the second inclined groove 1503. 2 and the third slot section 1403, the first inclined slot 1501 and the second inclined slot 1503 are distributed in an "eight" shape, and a one-way valve structure is arranged at the junction of the first slot section 1401 and the second slot section 1402; the one-way valve structure includes a blocking rod 19, the blocking rod 19 is rotatably connected to the fixed plate 13, and an elastic member is arranged between the blocking rod 19 and the fixed plate 13, and the elastic member restores the deformation process to drive the blocking rod 19 to close the junction of the first slot section 1401 and the second slot section 1402. The elastic member can be specifically a tension spring or a tension spring, and the embodiment of the present invention specifically adopts a torsion spring, one end of the torsion spring is fixedly connected to the fixed plate 13, and the other end of the torsion spring is fixedly connected to the blocking rod 19.

[0032] See also Figure 6 and Figure 7 The sliding part 12 is rotatably connected to the shaft 7, and the sliding part 12 is slidably matched with the guide groove. When the sliding part 12 is in the second horizontal groove 1502, the gear 20 is meshed with the first rack 16. When the sliding part 12 is in a section of the second groove section 1402 located directly below the second horizontal groove 1502, the gear 20 is meshed with the second rack 17. In the outward travel of the sliding seat 4, the shaft 7 is used to make the sliding part 12 slide into the special-shaped groove 15 under the guidance of the one-way valve structure of the first groove section 1401, and finally slide from the other end of the special-shaped groove 15 to the third groove section 1403. In the return travel of the sliding seat 4, the shaft 7 is used to make the sliding part 12 slide from the third groove section 1403 through the second groove section 1402 and push open the one-way valve structure to the first groove section 1401. In addition, the sliding cooperation between the sliding part 12 and the guide groove also limits the rotation of the sliding seat 4 on the screw rod 6, so that when the screw rod 6 rotates, the sliding seat 4 itself will not deviate and rotate.

[0033] Working principle: Before automatically winding up the cable, the push-pull member 18 drives the first rack 16 and the second rack 17 to slide synchronously in the opposite direction, so that the gear 20 and the first rack 16 and the second rack 17 are not meshed during the reciprocating sliding of the sliding seat 4. When the cable is automatically wound up, the cable is passed between the driven wheel 9 and the driving wheel 8 and wound onto the winding drum 2. The motor 3 is started to drive the winding drum 2 and the screw rod 6 to rotate. The screw rod 6 rotates to drive the sliding seat 4 to slide back and forth, thereby realizing the reciprocating winding of the cable on the winding drum 2.

[0034] Before automatically unfolding the cable, the push-pull member 18 is used to drive the first rack 16 and the second rack 17 to slide synchronously in the opposite direction. When the sliding seat 4 is sliding back and forth, the gear 20 is meshed with the first rack 16 only by the switching assembly. When the sliding seat 4 is sliding back and forth, the gear 20 is meshed with the second rack 17 only by the switching assembly, so that when the sliding seat 4 is sliding back and forth along the axial direction of the winding drum 2, the gear 20 always drives the shaft 7 to rotate along the axial direction of the shaft 7 in the same direction, so that the driving wheel 8 on the shaft 7 always rotates in the same direction to transport the cable to the outside of the box 1. When automatically unfolding the cable, the motor 3 is started to drive the winding drum 2 and the screw 6 to rotate in the opposite direction, and the screw 6 rotates in the opposite direction to drive the sliding seat 4 to slide back and forth. During the sliding stroke, the shaft 7 rotates to drive the driving wheel 8 to rotate together, so that the cable on the winding drum 2 is transported from between the driving wheel 8 and the driven wheel 9 to the outside of the box 1.
