Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) testing technology, and in particular to a placement platform for UAV testing and calibration. Background Technology
[0002] Drone performance testing is a highly demanding task, as any inaccuracy in the data can easily lead to deviations in the test results. Drone testing typically begins on a drone placement platform. The terrain of the testing environment is unpredictable, and when encountering uneven ground, the placement platform cannot guarantee a level installation. If the drone gimbal has an automatic adjustment function, a shift in the initial gimbal angle may cause the system to be unable to distinguish whether it is due to the drone itself or the platform's levelness, leading to inaccurate test conclusions. If the drone gimbal lacks an automatic adjustment function, the resulting test data may result in misjudgments of the drone's performance. Currently, shims are commonly used to adjust the level, but this cannot achieve stepless adjustment across multiple angles, and the levelness of the placement platform always has a slight error. Utility Model Content

The lower substrate is arranged vertically below the upper substrate, and multiple level rulers are fixedly provided on the side of the upper substrate. The lower substrate and the upper substrate are connected by multiple evenly arranged level adjustment mechanisms.
[0005] The horizontal adjustment mechanism includes a locking member, an inner adjusting sleeve, an outer adjusting sleeve, and a fastener. The upper base plate has multiple upper through holes. The bottom end of the locking member is connected to the lower base plate, and the top end of the locking member passes through the upper through holes and is connected to the fastener. The fastener can move up and down along the length of the locking member. The inner adjusting sleeve is sleeved on the locking member, and the outer adjusting sleeve is threaded inside the inner adjusting sleeve. The inner adjusting sleeve and the outer adjusting sleeve are located between the upper base plate and the lower base plate.

[0006] The beneficial effects of this utility model are: This utility model is equipped with multiple horizontal adjustment mechanisms. By rotating the inner sleeve and the outer sleeve relative to each other, the relative movement of the inner sleeve and the outer sleeve in the vertical direction is realized, thereby adjusting the level of the upper substrate; Since the inner sleeve and the outer sleeve are connected by threads, stepless adjustment of multiple angles is realized.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the locking device is a bolt, the fastener is a nut, and the lower base plate is provided with a lower through hole coaxially arranged with the upper through hole.

[0010] Furthermore, a washer is provided between the nut and the upper surface of the upper substrate.
[0011] The beneficial effects of adopting the above-mentioned further solution are: the setting of the washer can prevent the nut from being damaged on the upper surface of the upper substrate when it rotates on the upper substrate, while ensuring the strength of locking the upper substrate.
[0012] Furthermore, the lower part of the lower through hole is provided with a receiving groove for accommodating the head of the bolt, and the head of the bolt is disposed in the receiving groove.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the setting of the receiving groove can prevent the bolt head from protruding from the lower surface of the lower substrate, which facilitates the placement of the lower substrate.
[0014] Furthermore, the head of the bolt is polygonal, and the receiving groove is a polygonal groove that matches the head of the bolt.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the head of the bolt is polygonal and a matching polygonal groove is provided, which can prevent the bolt from rotating during the adjustment of the level and facilitate the rotation of the nut.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the fastener uses a screw, which can be directly fixedly connected to the lower substrate.
[0018] Furthermore, the lower substrate is provided with a threaded mounting hole coaxially arranged with the upper through hole, and the bottom of the screw is threadedly connected to the threaded mounting hole.
[0019] The advantage of adopting the above-mentioned further solution is that it facilitates the detachable and fixed connection between the screw and the lower substrate.
[0020] Furthermore, the bottom outer wall of the adjusting inner sleeve is provided with a lower force-bearing protrusion.
[0021] The beneficial effect of adopting the above-mentioned further solution is that the setting of the lower force-bearing protrusion makes it convenient to use tools to restrict the inner sleeve of the adjustment, and prevents the inner sleeve of the adjustment from rotating synchronously when the outer sleeve of the adjustment is rotated.
[0022] Furthermore, the upper surface of the lower substrate is provided with a limiting groove, and the bottom of the adjusting inner sleeve is provided with a limiting member, which is inserted into the limiting groove.
