Embodiment Construction
[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0026] It should be noted that when an element is referred to as being "fixed on", "disposed on", "fixed on" or "mounted on" another element, it can be directly on the other element or an intervening element may also be present . When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is "fixedly connected" to another element, it can be fixed by any fixing method in the prior art, such as screw connection, snap-fastened connection,...

The invention discloses an antenna, a display system of antenna electrical downtilt and a transmission mechanism. The transmission mechanism comprises a first transmission assembly and a second transmission assembly, wherein the first transmission assembly comprises a first screw rod and a first transmission piece, the first transmission piece is spirally matched with the first screw rod in a matching way, the first transmission mechanism is provided with a first connection part and a second connection part, the second transmission assembly comprises a second screw rod, a third screw rod, a second transmission piece and a third transmission piece, the third screw rod is fixedly connected with the second screw rod in transmission way, the second transmission piece is spirally matched with the second screw rod in a transmission way, the third transmission piece is matched with the third screw rod in a transmission way, the thread rotation direction of the second screw rod is same as thethread rotation direction of the first screw rod and is opposite to the thread rotation direction of the third screw rod, the second transmission piece is provided with a third transmission part, andthe third transmission piece is provided with a fourth connection part. By the transmission mechanism, the graduation display sequences of scales corresponding to two phase shifters can be same, the display system employs the transmission mechanism, and the antenna employs the display system.
Description
technical field [0001] The present invention relates to the technical field of antennas, and in particular, to an antenna, a display system for the electrical downtilt angle of the antenna, and a transmission mechanism thereof. Background technique [0002] Among the antenna phase shifters, the straight-pull type phase shifter is widely used. The phase-shifting dielectric plates are all pushed into the cavity of the phase-shifter and the minimum electrical down-tilt angle of the phase-shifter can be obtained. The maximum electrical downtilt angle of the phase device is generally unified in the design scheme. [0003] However, in order to meet different design requirements, in some cases, the phase shifter scheme that is just the opposite of the above will be used, that is, the phase-shifting dielectric plate is fully pushed into the interior of the phase-shifter cavity, which can be the maximum electrical downtilt angle of the phase-shifter, while the phase-shifting dielectr...
