Experiments prove that compared with a common L-shaped adjusting plate, the first adjusting plate 10 with the arc-shaped structure has stronger bearing capacity under the same weight and lighter weight under the same load. Thus, the two-dimensional adjustable mounting apparatus using the arc-shaped first adjusting plate 10 enables the apparatus to be smaller in size while enhancing the structural strength.

The reinforcing wall 100 forms an angle of 90 ° with the first regulating plate 10 in a normal sectional plane passing through the center of the first regulating plate 10 to maximize the bending resistance of the first regulating plate 10.
According to the invention, the horizontal angle marks 102 uniformly distributed along the arc-shaped surface are arranged at the upper end and the lower end of the outer arc surface of the first adjusting plate 10, and are matched with the V-shaped notches 116 on the main body plate of the second adjusting plate 11, so that an operator can conveniently and accurately adjust the horizontal angle of the device from various angles during operation.

Specifically, the vertical angle indicator 114 is not disposed in the area covered by the head of the second adjusting bolt 23, so as to avoid the second adjusting bolt 23 from rubbing against the surface of the vertical angle indicator 114 to damage the surface when rotating along the arc chute 113.
The distance between the first adjusting hole 202 and the second adjusting hole 203 disposed on the vertical arm 201 is consistent with the distance between the first fixing hole 210 and the second fixing hole 211 on the angle indicating sheet 21 and the radius of the arc chute 113 on the rotating arm 110 of the second adjusting plate 11. So that the second adjusting plate 11 can rotate relatively with respect to the center two 1111 of the first slot 111 of the fixing base 20, and the angle indicator 21 can point to the corresponding vertical angle indicator 114 on the second adjusting plate 11 according to the actual relative angle therebetween.
The angle indicating sheet 21 has a rectangular sheet structure. The center distance between the first fixing hole 210 and the second fixing hole 211 on the angle indicating sheet 21 is equal to the center distance between the first adjusting hole 202 and the second adjusting hole 203 on the fixed base 20.
When the vertical angle adjusting device is installed, a first adjusting bolt 22 is used to sequentially pass through the first fixing hole 210 on the angle indicating sheet 21, the first adjusting hole 202 on the fixing seat 20 and the first slot hole 111 on the rotating arm 110 of the second adjusting plate 11, and a mating nut is screwed on; meanwhile, a second adjusting bolt 23 is used to sequentially pass through the second fixing hole 211 on the angle indicating sheet 21, the second adjusting hole 203 on the fixing base 20 and the second slotted hole 112 on the rotating arm 110 of the second adjusting plate 11, and a mating nut is screwed on, so that the assembly of the vertical angle adjusting device is completed.
Referring to fig. 1, 4 and 6, when the vertical angle of the vertical angle adjusting device of the two-dimensional adjustable antenna mounting apparatus is zero (i.e. no adjustment is made), and the fixing base 20 and the second adjusting plate 11 do not need to rotate relatively, the second adjusting plate 11 needs to be pushed toward the fixing base 20 until the first adjusting bolt 22 abuts against the circle center 1110 of the first slot 111. At this time, the bolt head of the first adjusting bolt 22 is inserted into the escape groove 1211 of the outer clamping plate 121, and the fixed seat 20 and the second adjusting plate 11 cannot rotate relative to each other under the combined action of the first slot hole 111 and the second slot hole 112. At this time, the antenna 5 is closer to the mounting rod 4, the cantilever length of the device relative to the mounting rod 4 is reduced, the structural stability is better, and therefore the reliability of the two-dimensional adjustable antenna mounting device is better.
When the vertical angle needs to be adjusted, the first adjusting bolt 22 and the second adjusting bolt 23 are loosened, and then the antenna 5 connected with the second adjusting plate 11 as a whole is pushed towards the direction away from the fixing base 20 until the second adjusting bolt 23 is separated from the range of the second slot 112 and enters the arc chute 113, and the first adjusting bolt 22 is still in the first slot 111. Then, the antenna 5 connected with the first adjusting plate 10 and the second adjusting plate 11 as a whole is rotated so that the antenna 5 rotates relatively with respect to the second 1111 of the circle center of the first slot 111 on the rotating arm 110 of the second adjusting plate 11, and the antenna 5 can be rotated to a preset vertical angle by combining with the vertical angle mark 114 pointed by the thin pointed structure 212 of the angle indicating sheet 21, and then the first adjusting bolt 22 and the second adjusting bolt 23 are locked, so that the vertical angle adjustment of the antenna 5 is completed.

The first base of the fixing base 20 has two third fixing holes 200 symmetrically disposed about a central plane in a length direction of the first base. The distance between the two third fixing holes 200 is the same as the distance between the two fourth fixing holes 301 on the clamp code 30, so that bolts can be used to respectively pass through the third fixing holes 200 on the fixing base 20 and the fourth fixing holes 301 on the clamp code 30 to connect the two into a whole.
The two third mounting holes 300 are symmetrical with respect to a center plane in the longitudinal direction of the first base, and the two fourth fixing holes 301 are symmetrical with respect to a center plane in the longitudinal direction of the first base. The distance between the two third mounting holes 300 is larger than the diameter of the conventional mounting rod 4.
Preferably, the gripping wall 302 has serrations 303, which serrations 303 are effective to engage with a mounting bar 4 of conventional diameter. When a preset pretightening force is applied to the screw assembly 31, the clamp 30 can be stably clamped on the mounting rod 4. And then the two-dimensional adjustable antenna installation device can be stably clamped on the installation rod 4.
The two-dimensional adjustable antenna mounting device can simultaneously realize large-range adjustment of the horizontal angle and the vertical angle, so that the application range is wide.
The first adjusting plate 10 in the two-dimensional adjustable antenna mounting device adopts an arc-shaped plate-shaped structure, so that the size of the device is smaller while the structural strength is improved, and the two-dimensional adjustable antenna mounting device is good in reliability and light in weight.
According to the vertical angle adjusting device in the two-dimensional adjustable antenna mounting device, when the vertical inclination angle is zero (namely, adjustment is not performed), the antenna 5 is closer to the mounting rod 4, the length of a cantilever of the device relative to the mounting rod 4 is reduced, and the device has better structural stability, so that the two-dimensional adjustable antenna mounting device has better reliability.
