[0016] The rotary multi-functional up-down target machine drives the targets on two target chute frames to rotate through the chute disk and the first worm gear in the rotating assembly.

[0018] For this rotary multi-functional up-down target machine, through a series of operations of the first bevel gear in the up-down linkage assembly, it can drive the up-down linkage assembly and the components on it to rotate a certain angle around the axis of the first fixed column, thus realizing the up-down movement of the targets, increasing the diversity of shooting training, and avoiding the problems of complexity and instability in operation in the traditional method that requires additional mechanisms or manpower to realize the up-down movement of the targets. For this rotary multi-functional up-down target machine, controlling the lifting motor through the set target machine control box can achieve the purpose of controlling the up-down movement of the targets, enabling the height of the targets to be effectively controlled and adjusted, and avoiding the problems of cumbersome operation and difficult precise control in the traditional method that requires manual adjustment of the target height.

[0031] Further, one ends of the two pressing rods 31 away from the second worm gears 30 are both fixedly connected to pressing shafts 32, the two pressing shafts 32 are respectively rotatably connected to two input end rotating plates at the lower end of the link telescopic assembly 33, and output moving shafts 34 are fixedly connected to the two input end rotating plates at the upper end of the link telescopic assembly 33.

[0032] Further, the chute plate 27 is located on the lower surface of the target plate 8. The target plate 8 is slidably connected between two target plate chute frames 7. The outer surface of the chute plate 27 is provided with a lifting chute 37. Both output moving shafts 34 are slidably connected to the inner wall of the lifting chute 37. When the two pressing shafts 32 approach each other, they can drive the link telescopic assembly 33 to stretch upward and rise.

[0033] Further, a lifting motor 35 is fixedly connected to the upper surface of the rotating frame 4. A second worm 36 is fixedly sleeved on the outer surface of the output shaft of the lifting motor 35. The second worm 36 is meshed with two second worm wheels 30. Two sets of drive wheels 39 are arranged on the target machine counterweight base 1. The drive wheels 39 are used to drive the rotary multi-functional up-down target machine to move on the corresponding laid track.

[0034] Further, when in use, the rotary up-down motor 38 is started through the target machine control box 2. The output shaft of the rotary up-down motor 38 can drive the worm shaft 19 and the first worm 20 thereon to rotate. When the first worm 20 rotates, it can drive the first worm wheel 6 to rotate. When the first worm wheel 6 rotates, it can drive the two target plate chute frames 7 and the target plate 8 thereon to rotate, thereby realizing the automatic rotation of the target plate 8, improving the convenience and efficiency of shooting training, and also avoiding the problems of inconvenient operation and low efficiency in the traditional method that requires manual rotation to adjust the target plate.

[0035] Further, the simultaneously rotating worm shaft 19 will also drive the second bevel gear 24 to rotate through the first bevel gear 21. The second bevel gear 24 can drive the large gear 25 to rotate through the gear shaft 23. When the large gear 25 rotates, through its meshing with the fixed gear plate 26, the large gear 25 can rotate a certain angle around the axis of the second worm 36 on the outer surface of the fixed gear plate 26, thereby driving the up-down linkage assembly and the components thereon to rotate a certain angle around the axis of the first fixed column 3, thereby realizing the up-down movement of the target plate 8, increasing the diversity of shooting training, and avoiding the problems of complex operation and instability in the traditional method that requires additional mechanisms or manpower to realize the up-down of the target plate.

[0036] Further, the target control box 2 is used to control the lifting motor 35 to drive the second worm 36 thereon to rotate. The rotating second worm 36 can drive the two second worm wheels 30 to rotate downward simultaneously. When the two second worm wheels 30 rotate downward, they can drive the two pressing shafts 32 to approach each other through the pressing rods 31 thereon. The approaching of the two pressing shafts 32 drives the link telescopic assembly 33 to stretch upward and rise. The upward stretching and rising of the link telescopic assembly 33 can make the two output moving shafts 34 on the two input end rotating plates at its upper end approach each other in the lifting chute 37, thereby driving the chute plate 27 and the target plate 8 thereon to move upward, so as to achieve the purpose of controlling the up and down lifting of the target plate 8, enabling the height of the target plate 8 to be effectively controlled and adjusted, and avoiding the need to manually adjust the height of the target plate in the traditional method, which is cumbersome to operate and not easy to accurately control.

[0037] Further, the chute disc 5 and the first worm wheel 6 in the rotation assembly are used to drive the target plate 8 on the two target plate chute frames 7 to complete rotation. The two can stably support the target plate 8 when it rotates, avoiding the problem that in the traditional method, when a single rotating shaft rotates, the single rotating shaft is subjected to the impact force transmitted from the target plate 8 during shooting and is prone to deformation and damage, affecting the progress of shooting training, providing stable support for the rotation of the target plate, and improving the stability and safety of shooting training.

[0038] Further, when shooting, the impact force of the bullet on the target plate 8 can be effectively offset by the impact resistance reinforcement assembly. When the impact force on the target plate 8 is transmitted to the two target plate chute frames 7, the two target plate chute frames 7 will transmit the acting force to the spring plate 12 through the two inclined fixing columns 11 on the first fixing block 10. After being subjected to the acting force, the spring plate 12 will rotate slightly by a certain angle with the inclined fixing column 11 as the axis, and at the same time drive the damping rubber wheels 13 on the spring plate 12 to move in the wheel groove 9. The contact surfaces between the damping rubber wheels 13 when moving in the wheel groove 9 are relatively rough and have a certain damping property, and can achieve a certain buffering effect when making relative movement, being able to offset part of the impact force. At the same time, when the damping rubber wheels 13 move in the wheel groove 9, the spring plate 12 itself will also produce a certain elastic torsional deformation to offset part of the impact force. When the spring plate 12 rotates slightly by a certain angle with the inclined fixing column 11 as the axis, it can drive the tension spring 16 to elastically stretch and deform, thereby offsetting the remaining part of the impact force. At the same time, after the excess impact force is offset, the tension spring 16 resets the spring plate 12 and the damping rubber wheels 13 to prepare for offsetting the impact force of the next shooting. By setting the impact resistance reinforcement assembly, the impact force of the bullet hitting the target plate 8 can be effectively offset, avoiding the problem that the impact force is transmitted to the equipment and causing damage to the equipment components, improving the durability and service life of the equipment, and reducing the maintenance cost.

[0039] Furthermore, due to the self-locking property of the engagement between the first worm 20 and the chute disc 5 in the tilting linkage assembly, the target board 8 can be stably fixed at any angular position during the rotation and tilting movement of the target board 8, avoiding the problem that external factors affect the stability of the rotation and tilting movement of the target board 8, and improving the stability and accuracy of shooting training.

[0040] Furthermore, due to the self-locking property of the engagement between the second worm gear 30 and the second worm 36 in the target board lifting assembly, the target board 8 can be stably fixed at any position during the lifting movement of the target board 8, avoiding the problem that external factors affect the lifting stability of the target board 8, and improving the stability and safety of the target board lifting.

[0041] Working principle: When in use, the rotation and tilting motor 38 is started through the target machine control box 2. The output shaft of the rotation and tilting motor 38 can drive the worm shaft 19 and the first worm 20 thereon to rotate. When the first worm 20 rotates, it can drive the first worm gear 6 to rotate. When the first worm gear 6 rotates, it can drive the two target board chute frames 7 and the target board 8 thereon to rotate, thereby realizing the automatic rotation of the target board 8.

[0042] Furthermore, the simultaneously rotating worm shaft 19 will also drive the second bevel gear 24 to rotate through the first bevel gear 21. The second bevel gear 24 can drive the large gear 25 to rotate through the gear shaft 23. When the large gear 25 rotates, through its engagement with the fixed gear plate 26, the large gear 25 can rotate a certain angle around the axis of the second worm 36 on the outer surface of the fixed gear plate 26, thereby driving the tilting linkage assembly and the components thereon to rotate a certain angle around the axis of the first fixed column 3, thereby realizing the tilting movement of the target board 8.

[0043] Furthermore, by controlling the lifting motor 35 through the set target machine control box 2 to drive the second worm 36 thereon to rotate, the rotating second worm 36 can drive the two second worm gears 30 to rotate downward simultaneously. When the two second worm gears 30 rotate downward, they can drive the two pressing shafts 32 to approach each other through the pressing rods 31 thereon. The mutual approach of the two pressing shafts 32 drives the link telescopic assembly 33 to stretch upward and rise. The upward stretching and rising of the link telescopic assembly 33 can make the two output moving shafts 34 on the two input end rotating plates at its upper end approach each other in the lifting chute 37, thereby driving the chute plate 27 and the target board 8 thereon to move upward, thereby achieving the purpose of controlling the up and down lifting of the target board 8.

[0044] Furthermore, the anti-impact reinforcement component can enable, when shooting, the impact force of the bullet on the target plate 8 to be transmitted to the two target plate chute frames 7. When the impact force on the target plate 8 is transmitted to the two target plate chute frames 7, the two target plate chute frames 7 will transmit the acting force to the spring plate 12 through the two inclined fixing columns 11 on the first fixing block 10. After being subjected to the acting force, the spring plate 12 will rotate slightly by a certain angle around the inclined fixing column 11, and at the same time drive the damping rubber wheels 13 on the spring plate 12 to move in the wheel groove 9. The contact surface between the damping rubber wheels 13 when moving in the wheel groove 9 is relatively rough and has a certain damping property, and can achieve a certain buffering effect when doing relative movement, and can offset part of the impact force. At the same time, when the damping rubber wheels 13 move in the wheel groove 9, the spring plate 12 itself will also generate a certain elastic torsional deformation to offset part of the impact force. When the spring plate 12 rotates slightly by a certain angle around the inclined fixing column 11 provided on it, it can drive the tension spring 16 to elastically stretch and deform, so as to offset the remaining part of the impact force. At the same time, after the excess impact force is offset, the tension spring 16 resets the spring plate 12 and the damping rubber wheels 13 to prepare for offsetting the impact force of the next shot.
