[0002] Cable reels are very common in our daily life, such as electrical cables, optical cables, network cables, etc. The manufactured cables are wound on a large reel of the same size, and the cables are rewound by a power mechanism, so that the cables can be pulled out when in use, and can be rewound on the reel when not in use for easy storage. However, when using current cable reels, the cables often encounter the problem of the cables on the first reel being wound in a messy way. This is because the weight of the cable itself or the heavy objects hung by the cable cause too much friction between the cable and the first reel, so that the cable will not be wound in parallel along the first reel.

[0020] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] See also Figure 1 The present invention provides a follow-up steering lifter, which includes a bracket 1, a first cable, a first mounting shaft 3, and a first guide mechanism 9 for guiding the first cable. A motor 5, a worm gear reducer 6 and a connecting rod 7 are arranged on the bracket 1. The output shaft of the motor 5 is connected to the input shaft of the worm gear reducer 6; the first mounting shaft 3 is fixedly arranged in the turbine of the worm gear reducer 6, and a first drum 8 is sleeved on the outer side of the first mounting shaft 3. The motor 5 can drive the worm gear reducer 6 to output a rotational torque, so that the first mounting shaft 3 rotates, so as to drive the first drum 8 installed on the first mounting shaft 3 to rotate, and the forward and reverse rotation of the drum is realized by the forward and reverse rotation of the motor 5. The first guide mechanism 9 is hinged on the connecting rod 7, the first cable is wound on the first drum 8, and the free end of the first cable passes through the first guide mechanism 9. In the past, the problem of the cable on the first reel 8 being tangled in a disorderly manner was often encountered. This was due to the cable's own weight or the weight of the item suspended by the cable, which resulted in too much friction between the cable and the first reel 8, preventing the cable from being wound in circles along the first reel 8. Under normal circumstances, the cable would be wound in circles along the first reel 8, and the present application provides a first guide mechanism 9. After the first cable extends out of the first reel 8, it passes through the first guide mechanism 9. Since the first guide mechanism 9 is hinged on the connecting rod 7, the first guide mechanism 9 will change direction with the first cable, so that even if the friction between the first cable and the first reel 8 is too large, the first guide mechanism 9 will play a certain guiding role along the axial direction of the first reel to avoid the situation where the first cable on the first reel 8 is tangled in a disorderly manner.

[0022] In practical applications, the first installation shaft 3 and the connecting rod 7 are arranged in parallel.

[0023] The worm gear reducer 6 adopts the RV110 worm gear reducer 6 to provide sufficient rotation torque.

[0024] In order to allow the cables to be wound in parallel along the first reel 8 in circles, the present application provides a first thread groove 81 for accommodating the first cable on the first reel 8, and the first thread groove 81 plays a role in guiding the cable.

[0025] In an optional embodiment of the first guide mechanism 9, the first guide mechanism 9 includes a first bearing 91 and a first pulley assembly 92. A first mounting hole 71 is provided on the connecting rod 7, the first bearing 91 is arranged in the first mounting hole 71, and the first pulley assembly 92 is connected to the first bearing 91. Baffles are also provided on both sides of the first reel 8 to prevent the first cable from being rolled out of the first reel 8, so as to store the first cable.

[0026] In an optional embodiment of the first pulley assembly 92, the first pulley assembly 92 includes a first pulley seat 921, a first rotating shaft 922, and a first pulley 923. The first bearing 91 is sleeved on the outer side of the first rotating shaft 922. The first rotating shaft 922 is fixedly connected to the first pulley seat 921; a first pulley 923 pin is provided on the first pulley seat 921; the first pulley 923 is sleeved on the outer side of the first pulley 923 pin; the free end of the first cable passes through the first pulley 923, and there is an annular groove on the first pulley 923. The first cable enters from the upper end of the first pulley 923 and extends from the lower end of the first pulley 923. Among them, there may be a situation where the first cable is tangled due to the excessive friction between the first cable and the first drum 8, and the first pulley 923 in the present application will change direction with the first cable, so that even if the friction between the first cable and the first drum 8 is too large, the first guide mechanism 9 will play a certain guiding role along the axial direction of the first reel, so that the first cable is wound along the first thread groove 81 when winding, and the first pulley 923 will change with the change of the position of the first cable wound on the first drum 8 to assist the first cable to be wound along the first thread groove 81 all the time, effectively offset the friction between the first cable and the first drum 8, and make it easier for the first cable to be wound in parallel along the first drum 8 in circles, so as to avoid the situation where the first cable on the first drum 8 is tangent to the first pulley 923. Compared with the prior art, the first pulley 923 can also avoid the wear of the steel wire, and in the process of pulling out or retracting the first cable, the first cable is tangent to the first roller, so that the first cable does not have the phenomenon of wear, and the effect of smoothly pulling out or retracting the first cable can be achieved.

[0027] In an optional embodiment, the present application further includes a second cable, a second mounting shaft, and a second guide mechanism 10 for guiding the second cable; the second mounting shaft is fixedly disposed in the turbine of the worm gear reducer 6; a second drum 4 is sleeved on the outer side of the second mounting shaft; the second guide mechanism 10 is hinged on the connecting rod 7; the second cable is wound on the second drum 4, and the free end of the second cable passes through the second guide mechanism 10. The present application sets up a second guide mechanism 10, and the second cable passes through the second guide mechanism 10 after extending from the second drum 4. Since the second guide mechanism 10 is hinged on the connecting rod 7, the second guide mechanism 10 will change direction with the second cable, so that even if the friction between the second cable and the second drum is too large, the second guide mechanism will play a certain guiding role along the axial direction of the second drum, so as to avoid the situation where the second cable on the second drum 4 is wound in a disorderly manner.

[0028] Specifically, the first guide mechanism 9 and the second guide mechanism 10 have the same structure, and the first reel 8 and the second reel 4 have the same structure, so that the present application has two winding structures.

[0029] In an optional embodiment of the second guide mechanism 10, the second guide mechanism 10 includes a second bearing 101 and a second pulley assembly 102; a second mounting hole 72 is provided on the connecting rod 7; the second bearing 101 is disposed in the second mounting hole 72; and the second pulley assembly 102 is connected to the second bearing 101. Baffles are also provided on both sides of the first drum 8 to prevent the first cable from being rolled out of the first drum 8, so as to store the first cable.

[0030] In an optional embodiment of the second pulley assembly 102, the second pulley assembly 102 comprises a second pulley seat 1021, a second rotating shaft 1022, and a second pulley 1023; the second bearing 101 is sleeved on the outer side of the second rotating shaft 1022; the second rotating shaft 1022 is fixedly connected to the second pulley seat 1021; a second pulley 1023 pin is provided on the second pulley seat 1021; the second pulley 1023 is sleeved on the outer side of the second pulley 1023 pin; the free end of the second cable passes through the second pulley 1023. There is an annular groove on the second pulley 1023, and the second cable enters from the upper end of the second pulley 1023 and extends from the lower end of the second pulley 1023. The second pulley 1023 will change direction with the second cable, so that even if the friction between the second cable and the second reel 4 is too large, the second guide mechanism 10 will play a certain guiding role along the axial direction of the second reel to offset the friction between the second cable and the second reel 4, making it easier for the second cable to be wound in parallel along the second reel 4 in circles, so as to avoid the situation where the second cable on the second reel 4 is wound in a messy way.

[0031] In order to allow the second cable to be wound in parallel along the second reel 4 in circles, the present application provides a second thread groove 41 for accommodating the second cable on the second reel 4, and the second thread groove 41 plays a role in guiding the cable.

[0032] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
