When the lifting wheel rotates, the lifting wheel carries the support column and the target on the lifting platform to rise and fall on the first lifting rod and the second lifting rod, thereby realizing the lifting and movement of the target.

[0003] The above-mentioned prior art controls the up and down height of the target through a lifting motor, and the rotating motor controls the rotation of the target. Although the up and down rotation is achieved, it is all controlled by the motor, which may increase the control cost; secondly, the bottom of the main body of the prior art is installed with a shock-absorbing pad. Although it plays a role in shock absorption all day long, it is inconvenient to move and transport. When moving the whole body in the training ground, it must be moved.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] A rotating automatic lifting target, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, it includes a base 10, on which a screw 12 is arranged, on which a target 13 is fixedly mounted, a cavity 22 is opened in the middle wall of the base 10, and the cavity 22 passes through the bottom wall of the base 10, a threaded sleeve 11 is fixedly mounted at the center position of the base 10, the bottom end of the threaded sleeve 11 extends into the cavity 22, and the screw 12 is threadedly connected with the threaded sleeve 11; a driving assembly is arranged in the cavity 22, and the driving assembly includes a servo motor 18 and a toothed plate 15 arranged below the screw 12, the output end of the servo motor 18 is connected to a rotating rod 17 through a coupling, and the rotating rod 17 is provided with a gear column 16 meshing with the toothed plate 15; four groups of supporting legs 30 are arranged at the bottom of the base 10.

[0028] When in use, through the provided driving assembly, the driving assembly can make the gear column 16 mesh with the tooth plate 15 through the rotation of the servo motor 18. When the gear column 16 drives the tooth plate 15 to move upward, the tooth plate 15 pushes the screw 12 upward. The screw 12 is threadedly connected with the threaded sleeve 11, so that the screw 12 can move upward while the screw 12 rotates. The rotation of the screw 12 can drive the target 13 to rotate, so that the target 13 can be automatically raised and lowered by rotation. When the target 13 rises, it can also rotate, which can better allow the trainees to perform target shooting training. The trainees can find the right time to shoot at the target 13, which can exercise the combat capability of the trainees.

[0029] At the same time, when the servo motor 18 rotates to drive the gear column 16 to rotate in the opposite direction, the tooth plate 15 drives the screw 12 to move downward, which can also achieve the effect of descending rotation. It is worth noting that the servo motor 18 of this solution is a forward and reverse rotating motor.

[0030] like Figure 2 , Figure 3 and Figure 5 As shown, a triangle plate is fixedly installed on the wall surface of the cavity 22, a servo motor 18 is fixedly installed on the triangle plate, a gear column 16 is fixedly inserted into the wall surface of a rotating rod 17, the other end of the rotating rod 17 is rotatably connected to the inner wall of the cavity 22, a rotating seat 14 is fixedly connected to the top of the tooth plate 15, and the rotating seat 14 is rotatably connected to the bottom of the screw 12. Guide rods 19 are also fixedly connected to the outer walls of the bottom of both sides of the tooth plate 15, and the other ends of the two guide rods 19 are fixedly provided with limit sleeves 21, and the limit rods 20 are movably inserted into the two limit sleeves 21. A bottom plate 23 is provided at the bottom of the cavity 22, the limit rod 20 is fixedly connected to the bottom plate 23, the bottom plate 23 is fixedly connected to the inner wall of the cavity 22 through an L-shaped connecting piece, and the connecting piece is connected to the bottom plate 23 and the inner wall of the cavity 22 through bolts; a battery 24 is installed at the bottom of the bottom plate 23.

[0031] Specifically, when the working switch of the servo motor 18 is turned on, the servo motor 18 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the gear column 16 to rotate. The tooth block on the gear column 16 meshes with the tooth block on the tooth plate 15, and the gear column 16 drives the tooth plate 15 to move up and down. When the tooth plate 15 moves up and down, the guide rod 19 drives the limiting sleeve 21 to move up and down, and the limiting rod 20 plays a limiting role on the limiting sleeve 21, thereby forming an upper and lower limit on the tooth plate 15, thereby ensuring the stability of the tooth plate 15 during the up and down movement.

[0032] like Figure 7 , Figure 6 and Figure 4 As shown, the support leg 30 is T-shaped, and the support leg 30 is fixedly connected to the bottom wall of the base 10. A contraction groove 31 is opened in the bottom wall of the support leg 30, and the bottom of the contraction groove 31 is arc-shaped. A shock-absorbing pad is also fixedly configured at the bottom of the support leg 30, which is not drawn in the figure.

[0033] A travel wheel 35 with adjustable height is arranged in the cavity of the contraction groove 31. A cylinder 32 is fixedly installed on the top wall of the cavity of the contraction groove 31, and the output end of the cylinder 32 is fixedly connected to a wheel frame 33. The wheel frame 33 is an inverted concave shape. The center positions of the two side walls of the travel wheel 35 are rotatably connected to connecting rods 34, and the other ends of the connecting rods 34 are fixedly connected to the corresponding wheel frames 33. It is worth noting that the battery 24 is electrically connected to the servo motor 18 and the cylinder 32.

[0034] Specifically, when the base 10 needs to be pulled to move to the training ground, the working switches of the four cylinders 32 are turned on synchronously, and the cylinders 32 push the wheel frame 33 downward, and the wheel frame 33 pushes the walking wheel 35 downward. After the walking wheel 35 extends out of the contraction groove 31, the walking wheel 35 contacts the ground, and the base 10 can be pushed and walked conveniently. When reaching the training ground, in order to avoid the problem that the walking wheel 35 is easy to walk or roll on the ground, the state of the cylinder 32 can be controlled again at this time, so that the wheel frame 33 drives the walking wheel 35 to retract into the contraction groove 31, so that the bottom wall of the support leg 30 will contact the ground, so that the stability of the base 10 can be ensured.
