[0017] In the above implementation of the embodiments of this disclosure, the counterweight chamber can be regarded as a throwable object for throwing simulation training. The user can hold the handle and throw it. The thrown counterweight chamber can slide relative to the guide rod via a guide slider. The tilt angle of the guide rod can be adjusted by adjusting the height of the telescopic rod. The thrown counterweight chamber can fall back under gravity, facilitating retrieval and repeated throwing, reducing labor costs. By setting a first buffer, the guide slider can be decelerated during its ascent and descent to prevent damage to the throwing training device and personnel injury, thus improving the device's lifespan and personnel safety. When the guide slider rises, it passes over the chuck and reaches above it. After the chuck passes the guide slider, it returns to a state where one end penetrates the chuck's telescopic through-hole. When the guide slider falls back, it contacts one end of the chuck, which is then caught by the portion of the chuck extending from the chuck's telescopic through-hole. The guide slider pushes the chuck to move. As the chuck moves, it retracts into the anti-reverse groove, releasing the restriction on the guide slider and decelerating it, thus increasing safety. In addition, the connection disclosed herein can be a detachable connection to facilitate easy assembly and disassembly.

[0018] Furthermore, since soldiers and other trainees can use throwing training devices to train in grenade throwing, their grenade throwing ability can be improved, thereby enhancing the quality, efficiency, effectiveness, and accuracy of grenade throwing—in other words, improving the overall quality and effectiveness of grenade throwing. Throwing training devices can also increase the pass rate of training subjects, facilitating the smooth and effective conduct of activities such as recruit training, thus improving the quality and effectiveness of combined training. Throwing training devices allow for multi-method combined training; training effectiveness can be measured by the height of the thrown object; and adjustments to height, angle, and orientation can assist in correcting movements. Moreover, throwing training devices are highly integrated and relatively comprehensive in function.

[0019] The training equipment provided in this embodiment includes the throwing training device described above. Since the throwing training device has the above-mentioned technical effects, the training equipment with the throwing training device should also have the corresponding technical effects.

[0027] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0028] In this disclosure, for ease of description, directional terms such as "upper" and "lower" generally refer to the "upper" and "lower" along the Z-axis direction in a three-dimensional coordinate system when the corresponding component is in use. Additionally, the directional terms "inner" and "outer" refer to the "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, the terms "first," "second," etc., used in this application are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0029] See Figures 1 to 5 In this embodiment, a throwing training device is provided, including: a mounting beam 1, a first support rod 21, and a telescopic rod 3; one end of the mounting beam 1 is connected to the first support rod 21, and the other end of the mounting beam 1 is connected to the telescopic rod 3. The telescopic rod 3 changes the angle between the mounting beam 1 and the horizontal plane by changing its own length; the mounting beam 1 has a stopper groove 101 and a guide rod 11 is fixedly connected thereto; the bottom wall of the stopper groove 101 has a claw telescopic through hole 102; the end of the mounting beam 1 is connected to a first buffer 12; and the guide rod 11... The upper sleeve is equipped with a guide slider 13, which is slidably connected to the guide rod 11 and fixedly connected to a counterweight chamber 14. The counterweight chamber 14 is connected to a handle 15. The first buffer 12 is used to decelerate the guide slider 13 when it comes into contact with the guide slider 13. The mounting beam 1 is also connected to a stopper 4, which includes a claw 41. One end of the claw 41 passes through the claw telescopic through hole 102. When the guide slider 13 comes into contact with one end of the claw 41, the claw 41 retracts into the stopper groove 101 under the action of the bottom wall of the stopper groove 101.

[0030] In an exemplary embodiment, the mounting beam 1 can be referred to as a crossbeam. The first support rod 21 and the telescopic rod 3 can be mounted via the first support frame 23 and the second support frame 24 described below, or they can be mounted on a pre-set base. The length of the telescopic rod 3 is adjustable, and by adjusting the length, the angle between the mounting beam 1 and the horizontal plane can be changed, i.e., the tilt angle can be adjusted, providing flexible adjustment. The first buffer 12 may have a structure similar to the second buffer 43 described below. For example, the first buffer 12 may include a buffer pressure cylinder and a buffer piston rod, one end of which extends from the buffer pressure cylinder. When this end is compressed, it can retract into the buffer pressure cylinder, increasing the pressure inside the buffer pressure cylinder for buffering. When the compression of the buffer piston rod stops, one end of the buffer piston rod can extend out of the buffer pressure cylinder for reset. The guide slider 13 slides relative to the guide rod 11. When the handle 15 is gripped for throwing, the guide slider 13 slides along the guide rod 11 and rises in height. The guide slider 13 can pass through the stopper 4 with a claw 41 and is subsequently decelerated by the first buffer 12. Next, the guide slider 13 can retract under gravity, facilitating reuse and reducing labor costs. During the retraction process, the guide slider 13 can contact the claw 41, pushing the claw 41 to move. During this movement, the claw 41 retracts into the claw telescopic through-hole 102, allowing the guide slider 13 to continue sliding. Through this process, the guide slider 13 can be decelerated. Subsequently, the guide slider 13 can contact another first buffer 12 for further deceleration. Deceleration reduces the risk of injury to personnel from the counterweight chamber 14, reduces the likelihood of device damage, and increases service life.

[0031] Furthermore, the anti-reverse device 4 also includes an anti-reverse device slider 42 and a second buffer 43. The second buffer 43 includes an anti-reverse hydraulic cylinder 431 and an anti-reverse piston rod 432. The anti-reverse hydraulic cylinder 431 is fixedly connected to the mounting beam 1. One end of the anti-reverse piston rod 432 extends out of the anti-reverse hydraulic cylinder 431. The lower part of the anti-reverse device slider 42 is located in the anti-reverse device groove 101. The other end of the pawl 41 is rotatably connected to the lower part of the anti-reverse device slider 42. One end of the pawl 41 is fixed to the anti-reverse device slider 42. A retaining spring 433 is provided. One end of the pawl 41 extends out of the pawl telescopic through hole 102 under the action of the retaining spring 433. When one end of the pawl 41 contacts the guide slider 13, the pawl 41 drives the retainer slider 42 to slide in the retainer groove 101. The upper part of the retainer slider 42 causes the retainer piston rod 432 to retract into the retainer hydraulic cylinder 431. One end of the pawl 41 rotates under the action of the bottom wall of the retainer groove 101 and retracts into the retainer groove 101.

[0032] In an exemplary embodiment, the second buffer 43 can decelerate the anti-reverse slider 42. The second buffer 43 can transmit the counter-thrust force to the guide slider 13 through the anti-reverse slider 42 and the pawl 41, thereby decelerating the guide slider 13 that is in contact with the pawl 41, thereby improving safety and increasing service life.

[0033] Furthermore, the throwing training device also includes: a first mounting base 16 and a second mounting base 17. One end of the first mounting base 16 is fixedly connected to one end of the mounting beam 1, and the other end of the first mounting base 16 is rotatably connected to the first support rod 21. One end of the second mounting base 17 is fixedly connected to the other end of the mounting beam 1, and the other end of the second mounting base 17 is rotatably connected to the telescopic rod 3. A guide rod 11 is fixedly disposed between the first mounting base 16 and the second mounting base 17. A first buffer 12 is disposed through the first mounting base 16 and also through the second mounting base 17. A buffer spring 18 is sleeved on the end of the guide rod 11 near the first mounting base 16. A guard plate 20 is connected to the mounting beam 1.

[0034] In an exemplary embodiment, the guard plate 20 can reduce damage to the mounting beam 1, reduce the impact of weather and other factors on the guide rod 11, and improve its service life. The guard plate 20 can be a polycarbonate plate. The guide slider 13 can be further decelerated by the buffer spring 18. The rotatable connection between the first mounting base 16 and the second mounting base 17 facilitates the adjustment of the tilt angle of the mounting beam 1.

[0035] Furthermore, a first magnet 19 is fixedly connected to the lower surface of the mounting beam 1, and a second magnet 131 is fixedly installed inside the guide slider 13. The magnetic poles of the first magnet 19 and the second magnet 131 are the same, so as to decelerate the guide slider 13 when it moves toward the first magnet 19. A graphite lubricating layer 132 is fixedly installed inside the guide slider 13 and is sleeved on the guide rod 11. The handle 15 includes a first handle 151 and a second handle 152. The first handle 151 is fixedly connected to the counterweight chamber 14, and the second handle 152 is connected to the counterweight chamber 14 in sequence through a hanging rope 153 and a hook 154. The counterweight chamber 14 contains a counterweight block 141 and is connected to a door 142.

[0036] In an exemplary embodiment, the first magnet 19 and the second magnet 131 achieve a deceleration effect, and the graphite lubrication layer 132 reduces the sliding resistance of the guide slider 13. Trainees can selectively use either the first handle 151 or the second handle 152 for throwing training, making the training method more flexible. The number of counterweights 141 can be flexibly adjusted as needed to meet diverse training requirements. Furthermore, the hatch 142 can be closed using a hatch pin that engages with it to prevent the counterweights 141 from detaching from the counterweight chamber 14.

[0037] Furthermore, the lower end of the first support rod 21 is fixedly connected to the first support frame 23, which is L-shaped. The throwing training device also includes a second support rod 22, the lower end of which is fixedly connected to one end of the second support frame 24, which is L-shaped. The other end of the second support frame 24 is rotatably connected to the lower end of the telescopic rod 3.

[0038] In the exemplary embodiment, the first support frame 23 and the second support frame 24 increase the stability of the device and also facilitate the assembly and disassembly of the device.

[0039] Furthermore, the first support frame 23 is fixedly connected to the first bogie 231, the first bogie 231 is rotatably connected to the second bogie 232, the second bogie 232 is rotatably connected to the sleeve 233, the sleeve 233 is used to install the barbell bar 201; the first support rod 21 is connected to the fly ring 211 and the barbell bracket 214; the first support rod 21 is fixedly connected to the barbell bar bracket 212, the barbell bar bracket 212 has a barbell bar bracket opening 213, the barbell bar bracket 212 is used to hang the barbell bar 201 through the barbell bar bracket opening 213; a reinforcing beam 234 is provided between the first support frame 23 and the first support rod 21, the reinforcing beam 234 is fixedly connected to the barbell plate mounting post 235, the barbell plate mounting post 235 is used to install the barbell plate 202.

[0040] In the exemplary embodiment, the inclusion of the sleeve 233, the fly ring 211, and the barbell holder 214 allows for flexible training options, providing convenience for trainees and improving the integration of the device. The barbell plate mounting post 235 provides space for storing the barbell plates 202, achieving a space-saving effect. The sleeve 233 can be used with the barbell bar 201, barbell plates 202, etc., for back muscle extension training, etc.; the fly ring 211 can be used for fly training, etc.; and the barbell holder 214 can be used with the barbell bar 201, barbell plates 202, etc., for weighted squat training, etc.

[0041] Furthermore, the first support frame 23 and the second support frame 24 are fixedly connected with a single bar 301 and a connecting beam 302; the second mounting base 17 is rotatably connected to the telescopic rod 3 via the telescopic rod connecting shaft 31. The telescopic rod 3 includes a lead screw 32 and a turntable 33. The turntable 33 is connected to the lead screw 32. The rotation of the turntable 33 is transmitted to the lead screw 32, causing the lead screw 32 to extend and retract to change the length of the telescopic rod 3.

[0042] In an exemplary embodiment, the horizontal bar 301 allows for selective training, such as pull-up exercises. The relative positions of the horizontal bar 301 and the first support frame 23, as well as the relative positions of the horizontal bar 301 and the second support frame 24, can be flexibly adjusted, i.e., the height of the horizontal bar 301 can be adjusted. The turntable 33 facilitates the adjustment of the length of the telescopic rod 3.

[0043] Furthermore, the second support frame 24 is fixedly connected to the first bed frame support 51, the first bed frame support 51 is slidably connected to the bed frame support seat 52, the bed frame support seat 52 is rotatably connected to the second bed frame support 53, the second bed frame support 53 is fixedly connected to the first bed frame 401, the first bed frame 401 is rotatably connected to the second bed frame 402, the second bed frame 402 is rotatably connected to the bed frame support rod 403, and the second bed frame support 53 is provided with a bed frame limiting plate 54. 4 is used to hold one end of the bed support rod 403 to limit the relative rotation between the first bed 401 and the second bed 402; a bed limit pin 55 is provided on the bed support seat 52, which is used to limit the relative sliding between the bed support seat 52 and the first bed bracket 51; the first bed 401 is rotatably connected to a leg limit frame 404, and the leg limit frame 404 is fixedly connected to a leg weight column 405, which is used to mount the barbell plate 202.

[0044] In an exemplary embodiment, the rotation of the second bed frame 53 can cause the first bed frame 401 and the second bed frame 402 to rotate, thereby facilitating storage. The second bed frame 402 can rotate relative to the first bed frame 401, and by utilizing the bed frame limiting plate 54 and the bed frame support rod 403, the second bed frame 402 can form angles of 0°, 15°, 30°, and 45° with the horizontal direction. The relative sliding between the bed frame support base 52 and the first bed frame 51 is limited by the bed frame limiting pin 55, so that training can be conducted using the first bed frame 401 and the second bed frame 402. The trainee can lie on the first bed frame 401 and the second bed frame 402 to perform exercises such as bench presses and sit-ups. The relative movement between the leg restraint frame 404 and the first bed 401 can be limited by corresponding limit pins to restrict the trainee's legs. The corresponding limit pins can be removed, and barbell plates 202 can be fitted onto the leg weight column 405 for strength training such as leg flexion and extension. This diverse training option provides convenience for the user, improves integration, and saves space. Corresponding limit pins (e.g., bed limit pins 55) can be installed through the second bed frame 53 and bed support base 52 to allow for... Figure 2 After the bed is stowed away, the relative movement between the second bed frame 53 and the bed support 52 is restricted, providing space for another training session.

The first Roman stool support 61 is rotatably connected to the Roman stool support rod 63. The second Roman stool support 62 is fixedly provided with a Roman stool limiting block 64, which is used to limit one end of the Roman stool support rod 63 to limit the relative rotation between the first Roman stool support 61 and the second support frame 24.

[0046] In the exemplary embodiment, training such as goat extension can be performed using the first Roman stool support 61 and the second Roman stool support 62. The relative rotation between the first Roman stool support 61 and the second support frame 24 can be limited by the cooperation of the Roman stool limiting block 64 and the Roman stool support rod 63, thus achieving the effect of convenient assembly.
