[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 , Figure 2 As shown;

[0037] The present invention discloses an online two-dimensional rotation adjustment device for a reflector, the adjustment device comprising:

[0038] Support frame 1; and

[0039] A reflector assembly 2 arranged in the support frame 1;

[0040] An azimuth adjustment mechanism 3 installed on both sides of the reflector assembly 2 is used to adjust the swing angle of the reflector assembly 2, and one end of the azimuth adjustment mechanism 3 away from the reflector assembly 2 is connected to the support frame 1;

[0041] The regulating device also includes:

[0042] The pitch adjustment mechanism 4 has an adjustment end and an elastic end, wherein the adjustment end is connected to the reflector assembly 2 , and the elastic end is connected to the support frame 1 .

[0043] As a further introduction to this embodiment, the support frame 1 includes a base 101; and

[0044] A side cover 102 is fixed on the base 101 , and the side cover 102 provides lateral support for the orientation adjustment mechanism 3 .

[0045] As a further introduction to this embodiment, the reflector assembly 2 includes a reflector chamber 201; and

[0046] The reflector 202 is installed in the reflector chamber 201 , and the reflector 202 is pressed by a reflector pressing sheet 203 .

[0047] As a further introduction to this embodiment, the azimuth adjustment mechanism 3 includes a slideway fixing seat 301; and

[0048] The azimuth adjustment slider 302 is fixed on the slideway fixing seat 301 via a rolling pin 303.

[0049] The azimuth adjustment slide 304 and the positioning seat 308 are both fixed on the side cover 102 and cooperate with the azimuth adjustment slider 302 to determine the movement direction;

[0050] A reflector fixing pin 305 is installed on the azimuth adjustment slider 302 with clearance fit with an axial adjustment gasket 306, and the axial adjustment gasket 306 plays a role in adjusting the axial displacement of the reflector chamber 201;

[0051] An orientation adjustment spring 307 is connected to the positioning seat 308 and the slideway fixing seat 301 to elastically support the slideway fixing seat 301;

[0052] The sliding pin 310 is fixed to the positioning seat 308 and connected to the slideway fixing seat 301. The azimuth adjustment slider 302 drives the reflector chamber 201 to move through the reflector fixing pin 305. The reflector fixing pin 305 and the two sides of the reflector chamber 201 are respectively matched with each other in clearance, so that the axial adjustment gasket 306 contacts the reflector chamber 201. The slideway fixing seat 301 plays the role of connecting the sliding pin 310 and the azimuth adjustment slider 302. The movement of the slideway fixing seat 301 on the sliding pin 310 realizes the azimuth rotation of the reflector.

[0053] As a further introduction to this embodiment, the pitch adjustment mechanism 4 includes a pitch adjustment frame 401 , one end of which is connected to the reflector assembly 2 , and the other end of which is connected to the base 101 via a pitch adjustment spring 402 .

[0054] The present invention provides an online two-dimensional rotation adjustment device for a reflector. When working, the azimuth adjustment spring 307 is compressed by the movement of the slide drive block on the sliding pin 310, so that the azimuth adjustment slider 302 moves along the azimuth adjustment slide 304 with the reflector chamber 201, thereby realizing precise adjustment of the azimuth angle of the reflector. The pitch adjustment spring 402 is compressed by the pitch adjustment frame 401 to drive the reflector 202 to rotate around the reflector fixing pin 305, thereby realizing precise adjustment of the pitch angle of the reflector.

[0055] Since the two-dimensional rotation adjustment angle of the reflector 202 is required to be high, a precise measuring instrument such as a theodolite is required to directly measure the position accuracy after each movement. The specific process is as follows: a crosshair is engraved at the center of the reflector 202, and the theodolite is aligned with the center position of the reflector 202. The azimuth adjustment spring 307 is compressed by the movement of the slideway drive block on the sliding pin 310 to achieve the azimuth angle adjustment of the reflector 202, and the azimuth position of the reflector crosshair is measured multiple times, and the azimuth position accuracy of the crosshair is calculated, and then the azimuth adjustment accuracy of the reflector 202 is obtained. The pitch adjustment spring 402 is compressed by the pitch adjustment frame 401 to drive the reflector 202 to adjust the pitch angle, and the pitch position of the reflector crosshair is measured multiple times, and the pitch position accuracy of the crosshair is calculated, and then the pitch adjustment accuracy of the reflector 202 is obtained.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
