Description

The utility model relates to an antenna driver, in particular to an extremely convenient and stable antenna driver.

Antenna driver in the past, please refer to shown in Fig. 1, and it comprises transmission device 5 and telescopic device 8; There are connecting holes 521 and connecting grooves 522 perpendicular to the connecting holes 521; the telescopic device 8 includes a lead screw 81, a telescopic rod 82, an outer sleeve 83 and a driving guide block 84, and the telescopic rod 82 is arranged in the outer sleeve 83 , one end is equipped with a driving guide block 84, the inner wall of the driving guide block 84 is provided with a female thread 841 to engage with the lead screw 81, the lead screw 81 is arranged in the telescopic rod 82, and one end is provided with a socket 811, which can be plugged 822 is inserted into the connecting groove 522 of the transmission shaft 52, so that the lead screw 81 can be driven by the transmission device 5 to rotate, because the rotation of the lead screw 81 is driven by the latch 822, therefore, when the transmission device 5 is activated, the lead screw is driven When 81 rotates, the driving guide block 84 can be moved on the lead screw rod 81, and the telescopic rod 82 is driven to telescopically slide in the outer sleeve 83. However, because the bolt 822 must bear a large torque, when the bolt 822 moves in the gear, the Because of the point contact, there is a phenomenon of stress concentration, which makes the latch 822 easy to be damaged, thereby reducing the service life of the machine, and it is a non-linear transmission, which tends to make the transmission unstable and reduce the use effect of the machine parts.

The main purpose of the present invention is to provide an antenna driver, which has the function of convenient and stable transmission of power, and can prolong the service life of the components.

The purpose of this utility model is achieved in the following manner:

An antenna driver, including a transmission device and a telescopic device; the transmission device includes a power mechanism, a driven gear, and the driven gear is driven by the power mechanism to rotate; the telescopic device includes a lead screw, a telescopic rod and an outer sleeve, and the telescopic rod is arranged on In the outer casing, the lead screw is arranged in the telescopic rod, and it is characterized in that: the transmission device is also provided with a pivot element, the pivot element is arranged at the center of the driven gear, and a pivot hole is arranged in the center, and the lead screw One end is fastened to the pivoting hole of the pivoting element, and a driving guide block is fixed at one end of the telescoping rod, and the inner wall of the driving guide block is provided with a female thread to engage with the lead screw.

The purpose of the utility model can also be achieved in the following manner: the pivoting element and the driven gear can be connected into one body.

The utility model has the advantage that since the transmission function of the telescopic device and the transmission device is pressed and fixed on the pivotal element by the lead screw, the combined connection mode therebetween is quite simple, and it is a linear transmission, and its transmission is relatively stable, and it can also It bears a large stress load and has the function of stabilizing the structure, which can solve the shortcomings of the past, so that the service life of the machine parts can be extended.

The antenna driver of the present utility model is described in detail below by preferred embodiments and accompanying drawings, in the accompanying drawings:

Fig. 1 is an exploded view of a conventional antenna driver.

Fig. 2 is an exploded view of the antenna driver of the present invention.

Fig. 3 is a sectional view of the antenna driver of the present invention.

Fig. 4 is a front view of the driven gear of the antenna driver of the present invention.

Please cooperate and refer to shown in Fig. 2 and 3, the antenna driver of the present utility model, it comprises transmission device 10 and telescoping device 20; 112 drives a group of gear sets 113 to transfer kinetic energy, and the driven gear 12 is meshed with the gear set 113, and rotates through the drive of the gear set 113. Please refer to Figure 4, which is a front view of the driven gear 12 of the present utility model. A fixing hole 121 is provided, and the pivoting element 13 is arranged and fastened in the fixing hole 121 at the center of the driven gear 12 (it can also be integrally formed with the driven gear 12 ), and has a pivoting hole 131 .

Telescopic device 20 comprises lead screw rod 21, telescopic rod 22, outer sleeve 23, and telescopic rod 22 is arranged in the outer sleeve 23, and one end thereof is provided with female screw hole 221, and driving guide block 24 is provided with a male screw thread 241 so that it can be connected with The telescopic rod 22 is locked, and the inner wall is provided with a female thread 242, which is engaged with the lead screw 21. The lead screw 21 is arranged in the telescopic rod 22, and one end thereof is connected and pressed to the pivot hole 131 of the aforementioned pivot element 13. So that when the lead screw 21 is rotated by the transmission gear 12 of the transmission device 10, it can drive the driving guide block 24 to rotate, so that the telescopic rod 22 locked on it can telescopically slide in the outer sleeve 23 to achieve adjustment. The efficacy of the antenna.
