A dual broadband dual polarization omni-directional ceiling antenna

Abstract

The invention relates to the technical field of antennas, Specifically, the invention relates to a dual-broadband and dual-polarization omnidirectional ceiling antenna, comprising a circular table frame cover, a sponge strip, a ji-shaped strip plate, a timing switch, a cylindrical slot, a motor, a battery, an antenna body, a Z-shaped support plate, a bearing circular plate, an arc cavity, an arc magnetic plate, an arc bayonet, a limiting ring block, a screw, a circular seal plate, an externally threaded pipe, a network connecting wire, an internally threaded ring, a barb, a movable pin and a groove. The invention adopts the clamping connection structure instead of the screw fixing connection, facilitating removal of the antenna body without the removal of the screw tool, it is advantageousto change the installation method flexibly according to the situation, so that it is strong in firmness, The invention realizes the function of intermittently and regularly cleaning the dust, which is advantageous to dust cleaning of the whole antenna shell surface, and is advantageous to dust cleaning of the whole antenna shell surface through the rotating sponge strips which are abutted on thesurface of the round table frame cover and the size of the cross section structure of the multi-shaped strips is larger than the size of the cross section structure of the round table frame cover, thereby facilitating dust cleaning of the whole antenna shell surface.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-broadband dual-polarization omnidirectional ceiling-mounted antenna. Background technique [0002] Ceiling antenna is a kind of mobile communication system antenna, mainly used for indoor signal coverage, outdoor signal coverage is used for plate antenna, high power, strong signal, long coverage, relatively speaking, indoor coverage, such as venues, hotels , Office buildings, movie theaters, residential buildings, etc. need to be covered by indoor distributed systems, and small ceiling antennas are used. With the brand logo of China Mobile or China Unicom, you can tell whose system is covering it at a glance. The white downward cap is the antenna body, which radiates signals outward, and the upward bending rope is the feeder line, which leads the signal from the mobile base station to the Although the internal structure of the ceiling antenna is small in size, because it...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a dual-broadband dual-polarization omnidirectional ceiling antenna in order to solve the above problems, which adopts a clamping connection structure instead of screw fixing connection, so that the whole antenna can be easily removed without dismounting screw tools, and has It is beneficial to flexibly change the installation method according to the situation, and it has strong firmness. By pulling the barb from one side of the external threaded pipe to the other side of the external threaded pipe, after the placement is completed, the barb acts on the torsion spring of the movable pin set Next, make the barb end of the barb buckle on the edge surface of the inner port of the hole, so that the antenna can be installed on the ceiling as a whole, which is conducive to flexible replacement of the installation method according to the situation, and has strong firmness. The top of the inner wall of the arc cavity is Inclined surface structure, and the inner space of the circular arc cavity is gradually narrowed, so the round table frame cover is fixed on the wall by screws in the circular arc cavity and the circular arc clamping hole, and the clamping connection structure is used instead of the screw fixed connection, which is convenient in the absence of Remove the whole antenna while removing the screw tool; realize the function of cleaning dust intermittently and regularly, which is conducive to cleaning the surface of the overall antenna shell, and the rotating sponge strip is attached to the surface of the round table frame cover and the several-shaped strips The cross-sectional structure size is larger than the cross-sectional structure size of the round table frame cover, which is conducive to cleaning the dust on the surface of the antenna as a whole. The timing is controlled by the motor, the timing switch and the battery installed with the timer, and the installer sets the intermittent cycle of the timer in advance. The switch is powered on and off, thus realizing the function of cleaning dust intermittently and regularly
