DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 A portable UAV aerial survey target is shown, including a fixed plate 1 with a support assembly for measurement hinged on the top, a marking plate 4 is arranged on the top of the support assembly of the fixed plate 1, a connecting sleeve 401 for connecting the support assembly is arranged on the bottom of the marking plate 4, and a locking piece for locking the two is arranged between the connecting sleeve 401 and the support assembly.

[0023] A plurality of mounting holes 2 for integrally fixing the target are provided on the side of the top end of the fixing plate 1 .

[0024] It should be noted that the mounting hole 2 is a hole designed on a part for mounting the part. Most parts of a machine need to be designed with a mounting hole 2. The size of the mounting hole 2 should generally be larger than the size of the largest component of the equipment, and should preferably be a multiple of 0.5.

[0025] The support assembly includes a support frame 3, which can make it more convenient for the operator to handle the work. One of the support frames 3 is fixedly connected to the top of the fixed plate 1, and multiple support frames 3 are hinged in sequence along the vertical direction. A hinge block 5 is provided between the hinges of the multiple support frames 3 in the vertical direction, and positioning members for hinge positioning are provided on both sides of the hinges of the multiple support frames 3. Through the provision of the hinge block 5, the multiple support frames 3 can remain connected while being able to rotate, and the hinge block 5 is used for rotation compensation, so that the multiple support frames 3 can be rotated and folded and stacked together at the same horizontal height.

[0026] The positioning piece includes a locking sleeve 6 and a sliding sleeve 8, which are vertically symmetrically arranged on one side of the hinge of multiple support frames 3. The top of the sliding sleeve 8 is slidably connected with a locking pin 7, and the top of the locking pin 7 and the bottom of the locking sleeve 6 are slidably connected.

[0027] The inner wall at the top of the sliding sleeve 8 and the outer wall at the bottom of the locking pin 7 are sleeved with a traction spring 901. The traction spring 901 is arranged on both sides of the sliding sleeve 8 along the horizontal longitudinal direction. A toggle block 9 is arranged on one side of the bottom of the locking pin 7. A sliding opening is opened on one side of the sliding sleeve 8 along the vertical direction. The toggle block 9 is slidably inserted and connected in the sliding opening.

[0028] The top of one of the support frames 3 is slidably inserted into the connecting sleeve 401, and the locking member includes a locking rod 10 that is horizontally and centrally symmetrically slidably inserted into the two ends of the connecting sleeve 401, and the horizontally opposite sides of multiple locking rods 10 are respectively inserted into the top of the support frame 3.

[0029] The top and bottom ends of the locking rod 10 and the connecting sleeve 401 are provided with limiting grooves, and the top and bottom ends of the locking rod 10 are provided with limiting blocks 1001. The limiting blocks 1001 are slidably inserted and connected in the limiting grooves, and a supporting spring 11 is provided in the limiting grooves.

[0030] It should be noted that the supporting spring 11 always provides force to the locking rod 10 to keep it close to the support frame 3, so that the locking rod 10 can always remain close to the support frame 3 for insertion and locking, so that the marking plate 4 can be connected to the top of the support frame 3.

[0031] Working principle of this utility model:

[0032] After use, when the above-mentioned aerial survey drone image control point layout target needs to be folded, first pull the locking rod 10 in the direction away from the support frame 3. At this time, the insertion between the locking rod 10 and the support frame 3 is released, so that the mark plate 4 can be removed.
