Description

Technical Field

[0001] The invention belongs to the technical field of shooting training, and in particular relates to a lifting and lowering target machine. Background Art

[0002] In shooting training, target shooting is an indispensable training item. Usually, the target is placed on a simple device and fixed on the ground for shooting training.

[0003] At present, in order to cope with the flexibility of training and improve the rhythm of training, there are also many types of target shooting machines, such as automatic rotating lifting target machines, automatic target changing machines, multi-directional automatic target machines, etc. However, current target shooting is done by directly aiming and shooting when the shooting target is raised, while in actual combat, it is necessary to aim first and then confirm the personnel information, such as whether it is an enemy, a hostage, or one of your own, to avoid accidental injuries. This requires training the soldiers' immediate reaction ability, while the use of conventional target machines cannot train the ability to quickly identify targets.

[0004] Therefore, it is necessary to invent a lifting target machine to solve the above problems. Summary of the invention

[0005] In view of the above problems, the present invention provides a lifting and lowering target machine to solve the problems raised in the above background technology.

[0006] The present invention solves the technical problem by adopting the following technical solutions:

[0007] A lifting and lowering target machine comprises a base, a U-shaped mounting frame is fixedly installed on the upper side of the base, the U-shaped mounting frame is vertically arranged, two sprockets are rotatably installed on the inner side wall of the U-shaped mounting frame, a broken chain is sleeved on the two sprockets, the two ends of the chain are respectively fixedly connected to the two ends of the vertical rod, the chain is in a taut state, a No. 1 stepper motor is transmission-connected to the sprocket, the No. 1 stepper motor is fixedly installed on the base, a support plate is fixedly connected to the side wall of the vertical rod, a No. 2 stepper motor and a worm gear reducer are installed at the bottom of the support plate, the output shaft of the No. 2 stepper motor is connected to the input end of the worm gear reducer, and the No. 2 stepper motor is connected to the input end of the worm gear reducer. The stepper motor reduces the rotation speed through a worm gear reducer. The output shaft of the worm gear reducer passes through the support plate, reaches the top of the support plate and is fixedly connected with a cross bar. A target bar is rotatably installed on the end of the cross bar. A target plate is detachably installed on the end of the target bar. A No. 1 gear is sleeved on the target bar. A No. 2 gear is meshed on the No. 1 gear. The No. 2 gear is fixedly installed on the No. 3 stepper motor. The No. 3 stepper motor is fixedly connected to the cross bar. The No. 1 stepper motor, the No. 2 stepper motor and the No. 3 stepper motor are all connected to a control device. The control device is used to control the operation of the No. 1 stepper motor, the No. 2 stepper motor and the No. 3 stepper motor.

[0008] Through the above technical scheme, the cross bar can be driven to rotate through the worm gear reducer, and then the target rod can be driven to rotate, and the target board can be propped up, which can drive the target rod to rotate, thereby adjusting the cutting angle of the target board. While lifting and lowering, the target board can also be operated to make the target visible and invisible, which increases the practicality and improves the training effect. The height of the target board is also random, because when the No. 2 stepper motor is not working, the trainee cannot observe the position of the target board, which can improve the trainee's aiming speed.

[0009] As a further explanation of the lifting and lowering target machine described in the present invention, preferably, the control device includes a power module, a communication module, a main control circuit board and a PC end, and the No. 1 stepper motor, the No. 2 stepper motor, the No. 3 stepper motor, the communication module, and the main control circuit board are all electrically connected to the power module. The communication module receives the instructions sent by the PC end and transmits them to the main control circuit board. The main control circuit board drives the No. 1 stepper motor, the No. 2 stepper motor, and the No. 3 stepper motor to rotate according to the instructions.

[0010] Through the above technical solution, instructions can be applied through the PC to accurately control the independent operation of stepper motor No. 1, stepper motor No. 2, and stepper motor No. 3.

[0011] As a further description of the lifting target machine described in the present invention, preferably, the U-shaped mounting frame is made of bulletproof metal material, and the thickness of the U-shaped mounting frame is greater than mm.

[0012] Through the above technical solution, the bulletproof metal plate with a thickness of mm can achieve the effect of being unable to be penetrated by rifle bullets other than m, thus preventing off-target bullets from damaging the mechanical structure inside the U-shaped support plate.

[0013] As a further description of the lifting target lifting and falling machine described in the present invention, preferably, a counterweight is fixedly installed at one end of the cross bar away from the target plate, and the counterweight is used to balance the gravity of the target bar and the target plate.

[0014] The above technical solution makes the worm gear reducer run more smoothly.

[0015] As a further description of the lifting target lifting and falling machine described in the present invention, preferably, four locking universal wheels are installed at the bottom of the base.

[0016] The above technical solution facilitates the movement of the base and makes it more convenient to use.

[0017] As a further description of the lifting and falling target machine of the present invention, preferably, the characteristic quantities of the front and back sides of the target plate are different from each other.

[0018] Through the above technical solution, the trainee's ability to respond quickly while aiming can be trained.

[0019] Compared with the prior art, the present invention has the following beneficial effects: the lifting and lowering target machine of the present invention:

[0020] 1. The worm gear reducer drives the crossbar to rotate, and then drives the target bar to rotate. The target board is propped up, which can drive the target bar to rotate, so as to adjust the cutting angle of the target board. While lifting and lowering, the target board can also be operated to show and hide the target, which increases the practicality and improves the training effect. The height of the target board is also random, because when the No. 2 stepper motor is not working, the trainer cannot observe the position of the target board, which can improve the trainer's aiming speed;

[0021] 2. By setting the counterweight, the worm gear reducer can be made more stable during operation; by setting target plates with different characteristic quantities on the front and back sides, the trainee's ability to respond quickly when aiming can be trained.

[0029] When working, the control device controls the No. 1 stepper motor 6, the No. 2 stepper motor 8, and the No. 3 stepper motor 13 to work independently; when the No. 1 stepper motor 6 rotates, it can drive the sprocket 3 and the chain 4 to move, so that the vertical rod 5 moves up and down, thereby driving the target plate 10 to move up and down; when the No. 2 stepper motor 8 rotates, it can drive the cross bar 17 to rotate through the worm gear reducer 16, and then drive the target rod 9 to rotate, and prop up the target plate 10.
