However, the existing omnidirectional antenna is usually fixed to another connecting part by multiple sets of bolts. When disassembling and assembling, each set of bolt holes needs to be aligned before installation can be carried out. The operation is complicated, time-consuming and labor-intensive, resulting in low disassembly and assembly efficiency and increased labor costs. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 6As shown, the utility model provides an omnidirectional antenna that is easy to disassemble and assemble, including a connecting seat 1, the top of the connecting seat 1 is fixedly connected to a limiting ring 11, a base 4 is placed on the top of the connecting seat 1 at the inner side of the limiting ring 11, an omnidirectional antenna body 42 is arranged on the top of the base 4, a plurality of fixing mechanisms 3 are equidistantly arranged on the top of the connecting seat 1, the number of the fixing mechanisms 3 is set to be multiple, and the plurality of fixing mechanisms 3 all include a gear 301, the top of the gear 301 is fixedly connected to a first connecting column 302, the plurality of gears 301 are equidistantly arranged at the bottom of the connecting seat 1 near the edge, the top center of the gear 301 is fixedly connected to the first connecting column 302, and the first connecting The outer surface of the column 302 is fixedly connected to the limiting disk 303, and the second connecting column 304 is fixedly connected to the top center of the limiting disk 303, and the top of the second connecting column 304 is fixedly connected to the pressure rod 305. The outer surface of the first connecting column 302 slides through the outer surface of the connecting seat 1, the bottom of the limiting disk 303 and the top of the connecting seat 1 are in fit, and the bottom of the pressure rod 305 and the top of the base 4 are tightly fitted. The connecting shaft 2 is fixedly connected to the bottom center of the connecting seat 1, and the outer surface of the connecting shaft 2 is fixedly connected to the bearing 21, and the outer surface of the bearing 21 is fixedly connected to the toothed disk 22, and the outer surface of the toothed disk 22 and the outer surfaces of the multiple gears 301 are all meshingly connected.

[0025] The effect achieved by the entire embodiment 1 is that when the omnidirectional antenna body 42 needs to be installed, the base 4 at the bottom thereof is inserted into the limiting ring 11 at the top of the connecting seat 1, and then one of the pressure rods 305 is rotated to make it rotate to the top of the base 4. At the same time, the second connecting column 304 at the bottom of the pressure rod 305 drives the limiting plate 303 and the first connecting column 302 to rotate simultaneously. When the first connecting column 302 rotates, it drives the gear 301 at the bottom to rotate 180°, and when the gear 301 rotates, it synchronously drives the toothed disc 22 to rotate, and when the toothed disc 22 rotates, it synchronously drives the other gears 301 to rotate 180°, so that rotating one pressure rod 305 can drive all pressure rods 305 to rotate to the top of the base 4. A downward squeezing force is applied to it to achieve the effect of fixing the omnidirectional antenna body 42. When dismantling, one of the pressure rods 305 can be rotated to the outside of the base 4 to release the fixation of the omnidirectional antenna body 42 and the base 4. The disassembly and assembly is convenient and quick, which solves the problem of low disassembly and assembly efficiency, thereby reducing the labor cost during maintenance. The top edge of the base 4 is arc-shaped, and the bottom of the pressure rod 305 is slightly lower than the top height of the base 4. When it is rotated upward from the base 4, it will produce a slight deformation, thereby exerting a strong squeezing force on the base 4. The limit plate 303 is mainly used to limit the first connecting column 302. The toothed plate 22 is connected to the connecting shaft 2 through the bearing 21, so that the rotation is smoother and the friction is smaller.

[0026] Embodiment 2, as Figure 1-Figure 4As shown, a plurality of jacks 41 are equidistantly provided on the top of the base 4, a plurality of positioning columns 12 are equidistantly fixedly connected to the top of the connecting base 1, a guide column 13 is fixedly connected to the top of the positioning column 12, the guide column 13 is arranged in a conical shape, the outer surfaces of the guide column 13 and the positioning column 12 are fitted with the inner surface wall of the jack 41, the top of the pressure rod 305 is located away from the second connecting column 304, and is threadedly penetrated by a fastening bolt 306, the bottom end of the fastening bolt 306 is tightly fitted with the top of the base 4, and the bottom of the connecting base 1 is fixedly connected with a bottom shell 23 near the edge.

[0027] The effect achieved by the entire embodiment 2 is that, at the same time, when the base 4 at the bottom of the omnidirectional antenna body 42 is inserted into the limiting ring 11, the socket 41 on its surface is simply aligned with the guide column 13 on the connecting seat 1. Since the top of the guide column 13 is thinner, the insertion can be completed without precise alignment. Under the action of the guide column 13, the positioning column 12 and the socket 41 do not need to be precisely aligned to complete the precise insertion, thereby achieving the effect of limiting the base 4 so that it will not rotate inside the limiting ring 11, thereby improving the stability of the omnidirectional antenna body 42 during operation. At the same time, when the pressure rod 305 is pressed on the top of the base 4, the fastening bolt 306 can be rotated and tightened as needed to make its bottom further squeeze the top of the base 4, thereby improving the firmness between the base 4 and the connecting seat 1.

[0028] Working principle: When the omnidirectional antenna body 42 needs to be installed, the base 4 at the bottom is inserted into the limiting ring 11 at the top of the connecting seat 1, and then one of the pressure rods 305 is rotated to make it rotate to the top of the base 4. At the same time, the second connecting column 304 at the bottom of the pressure rod 305 drives the limiting plate 303 and the first connecting column 302 to rotate at the same time. When the first connecting column 302 rotates, it drives the gear 301 at the bottom to rotate 180°, and when the gear 301 rotates, it synchronously drives the toothed disc 22 to rotate, and when the toothed disc 22 rotates, it synchronously drives the other gears 301 to rotate 180°, so that rotating one pressure rod 305 can drive all the pressure rods 305 to rotate to the top of the base 4 to apply a downward squeezing force to it, thereby achieving the effect of fixing the omnidirectional antenna body 42. When removing, one of the pressure rods 305 can be rotated to the outside of the base 4 to release the omnidirectional antenna body 42. The base 4 is fixed and disassembled conveniently and quickly, which solves the problem of low disassembly efficiency, thereby reducing the labor cost during maintenance. Moreover, when the pressure rod 305 is pressed on the top of the base 4, the fastening bolt 306 can be rotated and tightened as needed to make its bottom end further squeeze the top of the base 4, thereby improving the firmness between the base 4 and the connecting seat 1. At the same time, when the base 4 at the bottom of the omnidirectional antenna body 42 is inserted into the limiting ring 11, the socket 41 on its surface is simply aligned with the guide column 13 on the connecting seat 1. Since the top of the guide column 13 is thinner, the insertion can be completed without precise alignment. Under the action of the guide column 13, the positioning column 12 and the socket 41 do not need to be precisely aligned to complete the precise insertion, thereby achieving the effect of limiting the base 4, so that it will not rotate inside the limiting ring 11, thereby improving the stability of the omnidirectional antenna body 42 during operation.
