DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 A cable retracting rack comprises a bottom frame 1 and a motor frame 2. A first support frame 3 and a second support frame 4 are respectively arranged on the symmetrical two side edges of the bottom frame 1. The motor frame 2 is connected to the first support frame 3. A retracting component 5 is mounted on the first support frame 3 and the second support frame 4. A driving component 6 arranged on the motor frame 2 is connected to the retracting component 5. A cable guide component 7 is arranged on the edge of the bottom frame 1 between the first support frame 3 and the second support frame 4. The first support frame 3 and the second support frame 4 are vertically fixed on the bottom frame 1. A bearing component 8 is arranged on each of the first support frame 3 and the second support frame 4.

[0025] Specifically, the first support frame 3 and the second support frame 4 are in a vertical plane and are arranged perpendicular to the bottom frame 1. After the drive component 6 is started, the retractable component 5 is selected for winding and releasing the cable. During the retracting and releasing process, the cable guide component 7 is used to guide the cable.

[0026] See also Figure 2 The bearing component 8 includes a bearing seat 81, a roller 82 and a roller 83. A strip groove is arranged on the bearing seat 81, and a semicircular groove connected to the strip groove is arranged on the top of the bearing seat 81. The roller 82 and the roller 83 are fixed to form a wheel set, and a plurality of wheels are arranged in the wheel set at equal intervals along the strip groove.

[0027] See also Figure 3The retractable component 5 includes a retractable shaft 51, a first side plate 52 and a second side plate 53. The first side plate 52 and the second side plate 53 are fixed to both ends of the retractable shaft 51 respectively. The retractable shaft 51 is placed in the semicircular groove and contacts the roller 82.

[0028] Specifically, the first side plate 52 and the second side plate 53 adopt a circular structure to limit the cable winding area, and the bearing seats 81 on both sides of the first support frame 3 and the second support frame 4 provide support for the roller 82 and the roller 83. A plurality of wheel groups are arranged, and when the retractable shaft 51 is placed in the semicircular groove, they are supported by the roller 82 and can reduce the friction of rotation while being supported by the roller 82.

[0029] Since the semicircular groove is adopted, it is convenient to place the retractable component 5 on the bearing component 8, and it is also convenient to remove the retractable component 5 from the bearing component 8.

[0030] See also Figure 4 The driving assembly 6 includes a reduction motor 61, a reduction shaft 62, a transmission belt 63 and a pulley 64. The reduction motor 61 is installed on the motor frame 2. One end of the reduction shaft 62 is connected to the shaft of the reduction motor 61 through a coupling. The pulley 64 is respectively fixed to one end of the reduction shaft 62 and the retractable shaft 51. The two ends of the transmission belt 63 are respectively connected to the two pulleys 64.

[0031] Specifically, after receiving the control signal, the reduction motor 61 also selects the reduction shaft 62, and transmits the power of the reduction shaft 62 to the retractable shaft 51 through the pulleys 64 on both sides, thereby driving the retractable shaft 51 to rotate forward or reverse.

[0032] See also Figure 5 The cable guide assembly 7 includes a guide motor 71, a motor screw 72, a support plate 73, a guide block 74, a first pulley 75 and a second pulley 76. The support plate 73 is fixed on the bottom frame 1. The guide motor 71 and the bracket are symmetrically arranged on the support plate 73. One end of the motor screw 72 is connected to the shaft of the guide motor 71, and the other end of the motor screw 72 is connected to the bearing on the bracket.

[0033] The guide block 74 is meshed with the motor screw 72, the bottom surface of the guide block 74 is in contact with the support plate 73, and the first pulley 75 and the second pulley 76 are symmetrically distributed on both sides of the guide block 74. The first pulley 75 and the second pulley 76 are both machined with concave annular grooves, and the first pulley 75 and the second pulley 76 are in contact with each other.

[0034] Specifically, the guide motor 71 drives the motor screw 72 to rotate after receiving the control signal, and the motor screw 72 is supported by the bracket. During the rotation of the motor screw 72, the guide block 74 is driven to move along the support plate 73. When the motor screw 72 rotates forward or reverse, it is used to control the reciprocating movement of the guide block 74, and the two annular grooves on the first pulley 75 and the second pulley 76 form a channel for the cable to pass through.

[0035] Working principle: when winding, the cable passes through the channel formed by the two annular grooves and then winds several turns on the winding shaft 51. The reduction motor 61 and the guide motor 71 synchronously receive the control signal, and respectively drive the winding shaft 51 and the motor screw 72 to rotate. When the winding shaft 51 is continuously rotating, the cable can be slowly wound on the winding shaft 51. In the winding process, the motor screw 72 rotates forward for a period of time and then reverses for a period of time, thereby realizing the reciprocating movement of the first pulley 75 and the second pulley 76 along the support plate 73, and slowly winding the cable on the winding shaft 51 layer by layer.

[0036] When unwinding, the reduction motor 61 receives a control signal and reverses, while the guide motor 71 does not receive a control signal, and the retractable shaft 51 reverses to slowly loosen the cable, and the user slowly pulls the cable to pull it out.
