Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of target drones, in particular to a rotation limiting mechanism for a rotating target drone. Background Art
[0002] Target drones are one of the commonly used training devices in training grounds. Some target boards on target drones need to rotate to simulate different shooting angles and adapt to different environments.
[0003] The turntable part of a rotating target drone usually uses rigid limit blocks, and the rotation range of the turntable is usually 180 degrees. However, for scenarios where the turntable needs to rotate 360 degrees, the existing rotating target drones cannot meet the requirements. Moreover, due to the use of rigid limit blocks, the turntable cannot rotate 360 degrees. Summary of the Utility Model
[0004] The main technical problem to be solved by the utility model is to provide a rotation limiting mechanism for a rotating target drone, which can enable the turntable to rotate 360 degrees and at the same time will not cut off the connection lines of other devices due to exceeding the limited range.
[0005] To solve the above technical problem, a technical solution adopted by the utility model is: to provide a rotation limiting mechanism for a rotating target drone, including: a fixed bracket, the fixed bracket is connected to the target drone, a turntable bearing is arranged on the fixed bracket, a movable turntable is installed on the turntable bearing, the movable turntable is connected to the target board, a limiting protrusion is arranged on the movable turntable, a movable limit block is movably connected to the fixed bracket, and the movable limit block is used to limit the position of the limiting protrusion, thereby limiting the rotation angle of the movable turntable.
[0006] Preferably, the movable limit block extends a limit rod towards the limiting protrusion, and the limit rod cooperates with the side surface of the limiting protrusion to limit the positions of the minimum angle and the maximum angle on the side surface of the limiting protrusion.
[0007] Preferably, a rotation hole is opened on the fixed bracket, and the movable limit block is movably connected to the fixed bracket through the cooperation of a stepped screw and the rotation hole.
[0008] Preferably, a support frame is arranged on the fixed bracket, the support frame includes a support plate and a limit plate, the movable limit block is movably connected to the support plate, and the two limit plates are respectively arranged on both sides of the movable limit block to limit the rotation angle of the movable limit block.
[0009] Preferably, a driving motor is arranged on the fixed bracket, a friction wheel is arranged on the main shaft of the driving motor, and the friction wheel rubs against the outer side surface of the outer ring of the turntable bearing to drive the movable turntable to rotate.
[0010] Preferably, mounting holes are opened on the movable turntable to facilitate the installation of the target board.
[0011] The beneficial effects of the present utility model are as follows: Through the cooperation of the movable limit block and the limit protrusion, the maximum rotation angle of the movable turntable is restricted. Through the movable connection of the movable limit block on the fixed bracket, the rotation angle restricted by the factor of the width of the fiber protrusion is compensated by changing the position of the movable limit block. Furthermore, the effect that the movable turntable can rotate 360 degrees and the maximum can only rotate 360 degrees is achieved. At the same time, the connection lines of other devices will not be cut off due to exceeding the limited range. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment:
[0028] Reference Figures 1-4 , a rotational limit mechanism for a rotating target drone, comprising: a fixed bracket 1, the fixed bracket 1 is connected to the target drone, a turntable bearing 2 is installed on the fixed bracket 1, the fixed bracket 1 is bolted to the inner ring 22 of the turntable bearing 2 by bolts, a movable turntable 3 is installed on the outer ring 21 of the turntable bearing 2, the movable turntable 3 is connected to the target board, so that when the outer ring 21 of the turntable bearing 2 rotates, it drives the rotation of the target board, a limiting protrusion 4 extends on the outer side surface of the movable turntable 3, a movable limiting block 5 is movably connected to the fixed bracket 1, the movable limiting block 5 is arranged to face the limiting protrusion 4 movably, and the movable limiting block 5 is used to limit the position of the limiting protrusion 4, thereby limiting the rotation angle of the movable turntable 3.
[0029] Reference Figures 4-6 , the movable limiting block 5 extends a limiting rod 51 towards the limiting protrusion 4. When the movable turntable 3 is in the 0-degree state and the 360-degree state, the limiting rod 51 abuts against the side surfaces on both sides of the limiting protrusion 4 respectively. Thus, the limiting rod 51 is used to limit the positions of the minimum angle and the maximum angle on the side surface of the limiting protrusion 4, and further limit the minimum angle and the maximum angle of the movable turntable 3. At this time, the minimum rotation angle of the movable turntable 3 is 0 degrees, and the maximum angle is 360 degrees.
[0030] Reference Figures 3-6, a rotating hole is provided on the fixed bracket 1, and the movable limit block 5 is movably connected to the fixed bracket 1 through the cooperation of the stepped screw 6 and the rotating hole. That is, one end of the movable limit block 5 is rotatably matched with the stepped screw 6, and the stepped screw 6 movably installs the movable limit block 5 on the fixed bracket 1. The support bracket 7 is screwed to the fixed bracket 1. The support bracket 7 includes a support plate 71 and a limit plate 72. The movable limit block 5 is movably connected to the support plate 71, and the two limit plates 72 are respectively arranged on both sides of the movable limit block 5, thereby restricting the maximum rotation angle of the movable limit block 5. These two limit angle positions are the positions when the movable rotation is at 0 degrees and 360 degrees. Thus, the movable limit block 5 can rotate at a certain angle, and further compensate for the width of the limit protrusion 4 by changing the rotation position, so as to achieve the effect that the movable turntable 3 can rotate up to 360 degrees.
[0031] Reference Figure 1 and Figure 2 , a driving motor 8 is bolted to the fixed bracket 1. A friction wheel 9 is installed on the main shaft of the driving motor 8. The friction wheel 9 rubs against the outer side surface of the outer ring 21 of the turntable bearing 2. Thus, when the driving motor 8 operates, it drives the friction wheel 9 to rotate, and further drives the movable turntable 3 to rotate.
[0032] Reference Figure 1 and Figure 2 , an installation hole 10 is provided on the movable turntable 3, which is convenient for installing the target plate by bolts.
[0033] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
