[0002] In military training, science exhibitions, and model enthusiast activities, howitzer model launcher simulation platforms are important auxiliary tools. They can intuitively demonstrate the firing principle of howitzers, the relationship between angle and trajectory, help learners quickly understand military equipment knowledge, and provide model enthusiasts with an immersive operating experience. Therefore, such devices are widely used in scenarios that require a concrete representation of the howitzer firing mechanism.

[0003] Currently, there are significant shortcomings in the simulated launch platforms for grenade launchers on the market: traditional platforms mostly use the direct pulling of rubber bands for launching, which can be dangerous during rebound; at the same time, the adjustment process lacks precise angle scale references, relying entirely on the user's experience to judge, making it difficult to guarantee the accuracy of the launch angle; in addition, most existing platforms do not have trajectory feedback functions, making it impossible to intuitively judge whether the trajectory of the grenade model meets expectations after launch, and the fixed support height cannot adapt to the height and table height requirements of different usage scenarios, making it difficult to meet the needs of teaching and popular science for intuitiveness and professionalism.

[0004] Therefore, a simulated launch platform for a howitzer model is proposed to solve the problem of precise angle adjustment. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a simulated launch platform for a grenade launcher, including a platform body 1, an adjustment component 2 slidably installed on the top of the platform body 1, a launch component 3 fixedly installed on the top of the adjustment component 2, and a feedback component 4 provided at the end of the top of the platform body 1 away from the adjustment component 2 for feedback on the grenade model's movement trajectory.

[0022] Furthermore, a telescopic support leg 5 is fixedly installed at the bottom of the platform body 1. The telescopic support leg 5 is used to support the platform body 1 and adjust the height of the platform body 1.

[0023] The telescopic support leg 5 can adjust the height of the platform body 1 according to the usage scenario, adapting to the operation needs of users of different heights and avoiding inconvenience caused by unsuitable platform height; at the same time, the telescopic support leg 5 can enhance the stability of the platform body 1 on different ground surfaces, prevent the platform from shaking during launch and affecting launch accuracy, and ensure the stability of the simulated launch process.

[0024] Please see Figure 1-4Furthermore, the adjustment assembly 2 includes a movable platform 201 slidably mounted on the top of the platform body 1 for adjusting the launch position. A rotary platform 203 is rotatably mounted on the side of the movable platform 201 away from the platform body 1. An adjustment seat 207 is fixedly mounted on the top of the rotary platform 203. An arc-shaped slide rail is provided on the top of the adjustment seat 207. A mounting seat 209 is slidably mounted on the top of the adjustment seat 207 via the arc-shaped track. A worm gear half-tooth ring 208 is fixedly mounted on the top surface of the mounting seat 209. A worm 211 is rotatably mounted on the bottom of the mounting seat 209 via a mounting ring 210. The worm 211 meshes with the worm gear half-tooth ring 208.

[0025] The rotary table 203 works in conjunction with the mounting base 209 to achieve dual adjustment of horizontal and pitch angles, meeting diverse launch angle requirements; the worm gear 211 meshes with the worm wheel half-tooth ring 208 for transmission, so there is no need to push the mounting base 209 forcefully when adjusting the pitch angle, and the transmission is smooth and the angle adjustment is more precise.

[0026] Furthermore, the rotary table 203 has a sliding groove inside, which runs through the side wall of the rotary table 203. A cylindrical locking pin 205 is slidably installed in the sliding groove. A return spring 206 is fixedly connected between the cylindrical locking pin 205 and the inner wall of the rotary table 203. A limit ring 204 is fixedly installed in the sliding groove to limit the cylindrical locking pin 205. The moving table 201 has several positioning holes 202 on its inner wall near the rotary table 203 to cooperate with the cylindrical locking pin 205.

[0027] The cylindrical locking pin 205 inside the rotary table 203 has a round head design. It cooperates with the positioning hole 202 of the moving table 201 to limit positioning without jamming. This not only avoids jamming when the rotary table 203 is adjusted, but also enables multi-position positioning to meet the requirements of different horizontal launch angles. The reset spring 206 can drive the cylindrical locking pin 205 to automatically reset, without the need for manual alignment of the positioning hole 202.

[0028] Furthermore, a scale is provided on one side of the top arc-shaped slide rail of the adjusting seat 207, and an observation window is provided on the side of the mounting seat 209 near the scale for observing the scale. The mounting ring 210 is fixedly installed on the bottom of the mounting seat 209 above the worm gear half-tooth ring 208.

[0029] The dial on the top of the adjusting seat 207 works in conjunction with the observation window of the mounting seat 209, allowing the user to directly read the pitch angle value, avoiding errors caused by judging the angle based on experience and improving the accuracy of angle adjustment; the mounting ring 210 stably mounts the worm 211 at the bottom of the mounting seat 209, ensuring that the worm 211 and the worm wheel half-tooth ring 208 always maintain a good meshing state, and preventing the worm from shifting during transmission, which would cause the angle adjustment to fail.

[0030] Please see Figure 4Furthermore, the launching assembly 3 includes a grenade model launching tube 301, which is fixedly installed on the top of the mounting base 209. A pull rod 303 is slidably installed at one sealed end of the grenade model launching tube 301. A push piston 302 is fixedly installed at one end of the pull rod 303 inside the mounting base 209. A storage spring 304 is fixedly connected between the push piston 302 and the inner wall of the grenade model launching tube 301.

[0031] The energy storage spring 304 of the launch assembly 3 can provide a stable launch thrust, push the piston 302 to slide smoothly, avoid jamming during launch, and ensure stable simulated launch effect.

[0032] Furthermore, the surface of the grenade launcher 301 is provided with an observation window for observing the position of the push piston 302. The surface of the grenade launcher 301 is provided with a scale located on one side of the observation window. A circular pull block is fixedly installed at one end of the pull rod 303 outside the grenade launcher 301 for pulling the pull rod 303.

[0033] The observation window and scale of the grenade launcher 301 allow for a clear view of the position of the piston 302 and precise judgment of the compression degree of the charge spring 304, thereby controlling the magnitude of the launch thrust and avoiding deviation in the launch trajectory due to improper charge. The circular pull block at the end of the lever 303 increases the contact area with the hand, making it easier for the user to pull the lever 303 and reducing the difficulty of the charge operation.

[0034] Please see Figure 5 Furthermore, the feedback component 4 includes a mounting groove 401, which is located on the surface of the platform body 1 at the end away from the adjustment component 2. A threaded rod 402 is rotatably mounted on the inner wall of the mounting groove 401. The end of the threaded rod 402 away from the inner wall of the mounting groove 401 passes through the platform body 1. A movable mounting block 403 is slidably mounted inside the mounting groove 401. The movable mounting block 403 is threaded onto the outside of the threaded rod 402. A grenade trajectory aiming frame 404 is fixedly mounted on the top of the movable mounting block 403. An extension rod 408 is fixedly mounted on the side wall of the platform body 1 near the feedback component 4. A grenade receiving frame 409 is slidably mounted on the outside of the extension rod 408 for collecting fired grenade models. A motor 410 is fixedly mounted on the side wall of the platform body 1. The output end of the motor 410 is connected to the end of the threaded rod 402 that extends out of the platform body 1.

[0035] The threaded rod 402 of the feedback component 4 drives the movable mounting block 403 to slide, which can adjust the position of the grenade trajectory aiming frame 404 to adapt to the trajectory detection requirements under different firing angles; the grenade receiving frame 409 slides along the extension rod 408, which can adjust its position according to the firing distance to ensure accurate collection of the fired grenade model and avoid the model falling, being damaged or lost.

[0036] Furthermore, an LED halo 405 is fixedly installed on the side of the grenade trajectory aiming frame 404 near the firing component 3 for providing feedback prompts on the passing of the grenade launcher model. A photoelectric sensor 406 is fixedly installed on one side of the grenade trajectory aiming frame 404 for detecting the movement trajectory of the grenade launcher model. An audio speaker 407 is fixedly installed on the top of the platform body 1 near the feedback component 4 for playing feedback prompts on the passing of the grenade launcher model.

[0037] The LED halo 405 of the grenade trajectory aiming frame 404 works in conjunction with the sound 407 to provide visual and auditory feedback on the accuracy of the trajectory when the grenade model passes through the aiming frame, which is more noticeable than single visual feedback; the photoelectric sensor 406 accurately detects the movement trajectory of the grenade model, avoiding the error of manual observation and judgment.

[0038] In actual operation, first adjust the telescopic support leg 5 at the bottom of the platform body 1, and adjust the height of the platform body 1 according to the usage scenario requirements to ensure platform stability; then push the moving platform 201 of the adjustment component 2 to slide along the top of the platform body 1 to the required launch position to complete the initial adjustment of the launch horizontal position.

[0039] Next, the rotary table 203 is rotated directly to adjust the angle. Because the cylindrical pin 205 has a round head, it cooperates with the positioning hole 202 to limit the position without jamming. The cylindrical pin 205 compresses the return spring 206 and slides along the slide groove. The limiting ring 204 restricts the sliding stroke of the cylindrical pin 205 to prevent it from dislodging from the slide groove. The return spring 206 resets and pushes the cylindrical pin 205 into the positioning hole 202 on the inner wall of the moving table 201 to achieve the positioning of the rotary table 203. Multiple sets of positioning holes 202 are provided to facilitate subsequent angle fine-tuning.

[0040] Then, rotate the worm 211 at the bottom of the mounting base 209. The worm 211 meshes with the worm wheel half-tooth ring 208, driving the mounting base 209 to slide along the arc-shaped slide rail at the top of the adjusting base 207. Observe the scale on the adjusting base 207 through the observation window on one side of the mounting base 209 to accurately adjust the pitch angle of the grenade launcher 301. After adjustment, grasp the circular pull block at the end of the pull rod 303 and pull the pull rod 303 outward. The pull rod 303 drives the push piston 302 to slide along the inner wall of the grenade launcher 301, compressing the energy storage spring 304. Observe the position of the push piston 302 through the observation window on the surface of the grenade launcher 301 and the scale on one side to determine the energy storage level.

[0041] The grenade model is placed into the grenade launch tube 301. The lever 303 is released, and the storage spring 304 resets, pushing the piston 302 to launch the grenade model from the launch tube. During the launch, the photoelectric sensor 406 of the feedback component 4 detects the trajectory of the grenade model. If the grenade model passes through the grenade trajectory aiming frame 404, the LED halo 405 lights up, and the sound 407 plays a prompt tone, realizing trajectory feedback. The motor 410 drives the threaded rod 402 to rotate, causing the movable mounting block 403 to slide along the mounting groove 401. The position of the grenade trajectory aiming frame 404 can be adjusted to adapt to trajectory detection at different launch angles, or the grenade trajectory aiming frame 404 can be turned into a moving target to improve interactivity. The launched grenade model finally falls into the grenade receiving frame 409, which is slidably installed outside the extension rod 408. The receiving frame 409 can be adjusted to adapt to different launch forces, completing the entire simulated launch process.
