Problems solved by technology

[0004] In the prior art, the multi-frequency antennas are mostly located outdoors at high altitudes. Considering natural environments such as wind loads and earthquakes, the antennas are prone to vibration. The antenna structure design in the prior art is unreasonable. During the vibration process, the phase shifting unit will move. , the moving phase-shifting unit will change the downtilt angle of the phase-shifting element, thereby changing the coverage of the antenna, affecting the user's receiving quality, and the stability of the antenna's performance cannot be effectively guaranteed

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0035] see Figure 1 to Figure 6 As shown, a long-distance transmission switching and self-locking device for a multi-frequency electric adjustable antenna of the present invention includes a support base 1. Of course, the support base 1 can be divided into several parts. In this embodiment, the support base 1 consists of a front base 22. The middle seat body 23 and the rear seat body 24 are formed. The support seat 1 is used to be fixed on an external frame. The blocking mechanism 2 drives a certain phase shifting mechanism 3 to adjust the downtilt angle of the antenna, thereby realizing the adjustment of the coverage of the antenna.

[0036] It also includes a self-locking member 4 fixedly arranged on the support base 1; the shift mechanism 2 includes a shift member 5 that is movably arranged relative to the support base 1, a first driving member for...

Abstract

The invention relates to the technical field of a multi-frequency electric modulation antenna and particularly discloses a multi-frequency electric modulation antenna long-distance transmission switching and self-locking device. The device includes a support base, a shifting mechanism disposed on the support base and multiple phase shifting mechanisms, wherein the shifting mechanism drives the phase shifting mechanisms to realize adjustment of the antenna, transition gears of the multiple phase shifting mechanisms are arranged along the moving direction of a shifting member, the self-locking member has multiple elastic buckles, the elastic buckles have self-locking teeth used for locking the transition gears of the phase shifting mechanisms, and the shifting member has an unlocking head used for driving the elastic buckles to generate elastic deformation to disengage the self-locking teeth from the transition gears. Only one shifting mechanism is required to drive the multiple phase shifting mechanisms through gear meshing, and structural design is simplified; phase shifter remote transmission is realized through setting the transition gears; each transmission of the multi-frequency antenna has a self-locking function through setting the self-locking member, that an antenna downtilt angle does not change in the vibration process is guaranteed, and stability of the antenna use performance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of multi-frequency electric adjustable antennas, and in particular discloses a long-distance transmission switching and self-locking device for multi-frequency electric adjustable antennas. Background technique [0002] A multi-frequency antenna is a commonly used antenna form. The multi-frequency antenna is configured with multiple phase-shifting units. In the prior art, the multi-frequency antenna is configured with two modes for adjusting the phase-shifting units. One is the type with an external motor. Each phase shifting unit is driven by a motor. The maintenance of the motor is simple, but the end face takes up a lot of space and the cost is high. The other is the built-in motor type. Although it can save space on the end face, because each phase shifting unit is still driven by a motor, and the motor is inside the antenna, maintenance is difficult and the cost is high. [0003] In addition, with more...
