[0002] An omnidirectional antenna radiates uniformly at 360° in the horizontal pattern, which is usually called non-directional. It has a beam of a certain width in the vertical pattern. Generally, the smaller the lobe width, the greater the gain. The omnidirectional antenna has a large coverage range. The omnidirectional antenna needs to be fixed when it is installed. Traditional devices are inconvenient for workers to install and fix the omnidirectional antenna because the installation place is high. External devices are required for fixing when the antenna is installed on a wall or steep place. A fixing device for fixing the omnidirectional antenna can bring convenience to the workers.

[0029] The use of the utility model:

[0030] First of all, it should be clear that the fixing device involved in the utility model is mainly used for the installation and fixing of cylindrical rod-like objects, which can be outdoors or on the roof. It should be noted here that when the altitude is high, it is necessary to add anti-falling and anti-falling steel ropes and expansion screws on the base 100 to fix the base 100 to the installation part to avoid the influence of wind force on the stability of the fixing device. The utility model takes the installation and fixing of the omnidirectional antenna as an example to explain its use method in detail. When the omnidirectional antenna needs to be installed, the operator first holds the holding part 246 and rotates it. The operator grasps the holding part 246 and rotates it while the second gear 244 is rotated together. The rotation of the second gear 244 can drive the first gear 241 meshing with it to rotate together with the screw 233. In addition, the threaded connection between the guide block 232 and the screw 233, and the guiding and limiting effect of the guide rail 231 on the guide block 232, the rotating screw 233 can drive the guide block 232 to slide the lifting cylinder 234 fixed thereto downward along the guide rail 231 until the fixing assembly 300 on the upper part of the lifting cylinder 234 is rotated to a height convenient for the operator to operate. Then, the operator selects a sleeve 302 with a corresponding inner diameter according to the diameter of the support rod of the omnidirectional antenna, and inserts the support rod of the omnidirectional antenna into the sleeve 302 with a corresponding inner diameter (in order to increase the support To improve the stability of the combination of the support rod and the sleeve 302, an internal thread can be provided inside the sleeve 302, and a partial external thread can be provided at the bottom of the support rod. When installing, it is only necessary to rotate the support rod clockwise, and when disassembling, it is only necessary to rotate the support rod interface counterclockwise). Then, the gripping portion 246 is rotated in the opposite direction to raise the omnidirectional antenna to the required height. After it is adjusted in place, the rotation of the second gear 244 is locked by screwing the locking bolt 247 upward until it is engaged in the tooth groove of the second gear 244, thereby greatly increasing the stability of the lifting cylinder 234 with the height adjusted. The utility model can realize convenient and quick adjustment of the height of the fixing assembly 300 by lifting and fixing the sleeve 302 , and the support poles of antennas with various diameters can be quickly fixed through multiple sleeves 302 with different apertures. There is no need for the operator to climb up, which makes the operation safer and more convenient, greatly improving the efficiency of installation and maintenance of the antenna support pole, making the operation more convenient, and solving the problem that the traditional antenna installation and fixation usually selects a fixing seat that is compatible with the antenna support pole. Because the installation place is high, it is inconvenient to install and fix the omnidirectional antenna. The operator needs to climb up and use bolts to tighten the fixing operation of the antenna support pole. This method is cumbersome to operate, and it is easy for the bolts to rust due to the erosion of rainwater, and it is troublesome to disassemble and assemble, and there are certain safety hazards.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
