[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0021] This utility model provides a multi-antenna lifting and rotating mechanism. Please refer to [link / reference]. Figure 1 and Figure 2The system includes a lifting rod 1, one end of which is mounted on an external device and the other end extends vertically upward. At least two sets of one-dimensional turntables 2 are installed on the lifting rod 1 for independently mounting load antennas. Each set of one-dimensional turntables 2 is also equipped with a wiring structure 3 on one side to drive the interconnection cables of the load antennas to rotate with the one-dimensional turntables 2.

[0022] Specifically, the lifting rod 1 is a multi-section rod structure, and each section can be independently equipped with the one-dimensional turntable 2 for mounting the load antenna.

[0023] Furthermore, all sections of the lifting rod 1 are electrically operated, using a screw and nut drive to control the lifting and lowering of each section. It is also equipped with a manual interface for manual operation.

[0024] Specifically, such as Figure 3 As shown, the lead screw and the nut at the bottom of the lifting rod 1 form a lead screw and nut helical pair, which converts the rotational motion into linear motion and drives each rod section to rise in sequence; and a lifting motor 4 is also provided, which is a power source and transmits power to the lead screw and nut helical pair through a gear set.

[0025] In one embodiment, the manual interface 5 is located at the bottom of the lead screw and nut screw pair to enable manual driving of each rod section to rise sequentially.

[0026] In this embodiment, please continue to refer to Figure 2 Taking the lifting rod 1 with an eight-section structure as an example, from bottom to top, the first section 101, the second section 102, the third section 103, the fourth section 104, the fifth section 105, the sixth section 106, the seventh section 107, and the eighth section 108 are connected in sequence.

[0027] The first rod section 101 has a threaded hole at its top for mounting a load antenna, and the one-dimensional turntable 2 is configured in three sets, respectively mounted on the third rod section 103, the fifth rod section 105, and the seventh rod section 107. In other words, the lifting rod 1 can accommodate no fewer than four types of antennas and has electric lifting and rotation functions.

[0028] The number of sections of the lifting rod 1 and the layout and quantity of the one-dimensional turntable 2 mentioned above are only one form in this embodiment. In actual use, the number of one-dimensional turntables 2 can be increased or decreased according to the number of sections of the lifting rod 1 and the height of the lifting of the sections.

[0029] Specifically, such as Figure 4As shown, the one-dimensional turntable 2 includes a housing 201, an antenna mounting flange 202, and a turntable mounting flange 203; the one-dimensional turntable 2 is connected to the flange at the top of the rod section through the turntable mounting flange 203 and is locked and fixed by countersunk screws; the antenna mounting flange 202 is located on one side of the housing 201 and is used to independently mount the load antenna.

[0030] In this embodiment, as Figure 5 As shown, the worm 6 in the worm gear structure is installed inside the housing 201, and the worm wheel 7 is connected to the antenna mounting flange 202. During operation, the worm wheel 7 drives the antenna mounting flange 202 to rotate.

[0031] Furthermore, the worm gear structure is also equipped with a rotary motor 8, which serves as a power source to drive the worm 6 to rotate.

[0032] Furthermore, the one-dimensional turntable 2 is also designed with a 10mm external hexagonal manual interface, which can be manually operated using a 10mm internal hexagonal hand crank. Furthermore, the one-dimensional turntable 2 has a built-in angle encoder, which is an absolute photoelectric encoder that can provide real-time feedback on the rotation angle. Based on the angle feedback, the servo controller controls the turntable to automatically adjust the angle.

[0033] Specifically, the wiring structure 3 includes a wiring frame 301 and a cable chain 302. The wiring frame 301 is conformally connected to the housing 201 of the one-dimensional turntable 2 and is fixedly connected to the housing 201 by screws. The fixed end of the cable chain 302 is fixed to the wiring frame 301 by screws, and the rotating end is electrically connected to the load antenna and fixed to the antenna mounting flange 202 by screws.

[0034] In this embodiment, the cable chain 302 is made of a flexible material, adapting to the bending of the cable as the one-dimensional turntable 2 rotates. With the cable routing structure 3 configured, the cable path during antenna rotation can be effectively planned, thereby providing effective protection for the cable.
