Technical Field

[0002] Air-to-ground laser communication is applied to the communication between drones and the ground. Due to the high calibration requirements of laser communication and the invisibility of lasers, it is difficult for us to judge whether the zero position of the laser communication device is calibrated by the naked eye. Therefore, it is necessary to add an external visible light laser pen for auxiliary calibration. For the airborne equipment, it is generally a spherical pod. It is difficult to accurately fix the laser pen on the pod, and there is no laser pen specifically applied to the spherical pod on the market. Each time of calibration, the laser pen can only be held by hand for calibration, with low accuracy and difficult to meet the calibration requirements. Summary of the Invention

The through holes correspond to the bolt holes on both sides of the connecting piece and are connected by a bolt and nut structure; the threaded hole is also connected to the bolt hole in the middle of the connecting piece by a bolt and nut structure; the size of the through hole is larger than that of the bolt hole, so that the rotating block can rotate a certain angle relative to the connecting piece in the horizontal position; four threaded holes are arranged on the upper surface of the rotating block, and an arc-shaped first groove is arranged in the middle of the four threaded holes.
[0007] A second groove adapted to the first groove is arranged below the fastening piece. The space formed between the first groove and the second groove is used to accommodate the laser pen. The laser pen is fixed in the second groove by an adhesive; four through holes corresponding to the threaded holes are arranged on the fastening piece, and bolts with springs are arranged thereon. The relative position between the fastening piece and the rotating block is adjusted by passing the bolts through the through holes and screwing them into the threaded holes.
[0008] As a further improvement of the utility model, the through hole is an arc-shaped through hole, and the center of the arc edge of the through hole is the center of the bolt hole in the middle of the connecting piece.

Detailed Embodiment
[0022] The present utility model will be further described below in combination with the embodiments in the drawings:
[0023] As Figure 1As shown in the figure, a laser pointer-assisted calibration device includes a connecting member 1, a rotating block 2, and a fastening member 3;
[0024] As Figure 2 shown, the connecting member 1 is located below and is used to connect the airborne pod. The air-to-ground laser communication consists of an airborne device and a ground device. The ground device is placed on the ground, and the airborne device mainly refers to the airborne pod, which is mounted by a drone. The airborne device generally adopts the form of a spherical pod; three bolt holes 11 are evenly distributed on the connecting member 1; an arc-shaped structure 12 is provided at the bottom of the connecting member 1 to facilitate adaptation to the structure of the airborne pod. For an airborne structure with an openable hole, the two sides can be fixed through bolts and the bolt hole 11 in the middle. For an airborne structure without an openable hole, the arc-shaped structure 12 can be glued to the airborne pod with strong glue;
[0025] As Figure 3 、 Figure 4 shown, the rotating block 2 is arranged above the connecting member 1. Two through holes 21 and one screw hole 24 are provided on the rotating block 2. The through holes 21 correspond to the bolt holes 11 on both sides of the connecting member 1 and are connected through a bolt and nut structure; the screw hole 24 and the bolt hole 11 in the middle of the connecting member 1 are also connected through a bolt and nut structure;
[0026] The size of the through hole 21 is larger than that of the bolt hole 11, so that the rotating block 2 can rotate a certain angle relative to the connecting member 1 in the horizontal position; the through hole 21 is an arc-shaped through hole, and the center of the arc of the through hole 21 is the center of the bolt hole in the middle of the connecting member 1; the through hole 21 includes two semi-cylindrical grooves 211 and a hollow area 212 in the middle of the semi-cylindrical grooves 211. The distance between the centers of the two semi-cylindrical grooves 211 is greater than zero; the distance between the centers of the two semi-cylindrical grooves 211 determines the rotation angle of the rotating block 2, and thus determines the amplitude of the adjusted azimuth angle. When the rotating block 2 rotates, it rotates around the center of the bolt hole in the middle of the connecting member 1;
[0027] Four threaded holes 22 are provided on the upper surface of the rotating block 2, and an arc-shaped first groove 23 is provided in the middle of the four threaded holes 22; As Figure 5 shown, a second groove 31 adapted to the first groove 23 is provided below the fastening member 3. The space formed between the first groove 23 and the second groove 31 is used to accommodate the laser pointer 4. The laser pointer 4 is fixed in the second groove 31 with adhesive; four through holes 32 corresponding to the threaded holes 22 are provided on the fastening member 3, and bolts with springs 5 are provided thereon. The relative position between the fastening member 3 and the rotating block 2 is adjusted by passing the bolts through the through holes 32 and screwing them into the threaded holes 22, thereby determining the range of the adjusted pitch angle of the laser pointer.
[0028] The outer sides of both the connecting member 1 and the rotating block 2 are provided with inclined patterns; the pattern directions of the connecting member 1 and the rotating block 2 are not parallel, which is convenient for increasing the frictional force of the hand when the rotating block rotates.
[0029] The working principle of the present utility model is as follows: When the empty end structure and the laser pointer are fixed through the connecting member, the emission direction of the laser pointer is adjusted. If the pitch angle needs to be adjusted, the bolts in the four threaded holes 22 can be screwed to finely adjust the pitch angle. Synchronous or asynchronous adjustment of the front and rear bolts can basically adapt to various pitch angle problems; when the azimuth angle needs to be adjusted, the azimuth angle can be adjusted by rotating the rotating block. The distance between the centers of the two semi-cylindrical grooves 211 in the through hole 21 determines the rotatable angle of the rotating block 2, as Figure 6 shown.
