Description

Technical Field

[0001] This invention relates to the field of throwing training devices, and more specifically to a slider assembly of a riot control grenade throwing auxiliary training device. Background Technology

[0002] Currently, when using military equipment such as riot control munitions for throwing training, problems such as lack of proficiency in the key points of the movements, inaccurate throwing posture, and lack of upper limb strength are quite prominent, resulting in short throw distances and inaccuracies. Trainees usually only use training munitions to conduct simple throwing technique training, training upper limb strength and throwing movements. Without such auxiliary equipment, in the long run, it will cause trainees to develop incorrect throwing movements.

[0003] In the field of track and field, in order to help shot putters or javelin throwers train, relevant technical personnel have designed corresponding throwing training devices. However, the throwing motion and posture of shot put or javelin are different from the throwing posture of riot control grenades, and cannot be directly applied to riot control grenades throwing auxiliary training.

[0004] In some existing throwing training devices, a guide rail and slider are used. The slider is guided by a guide rail with a specific arc shape to correct the trainee's improper throwing motion. However, the slider structure in existing technologies is too simple, only having a groove to cooperate with the guide rail. When the slider moves to the curved guide rail, it is prone to jamming, thus failing to simulate the training motion.

[0005] In the existing technology, the slider and the riot control training model are connected by a traction rope. After the riot control training model is thrown, it will exert a downward force on the slider under the action of gravity, which will affect the movement of the slider on the slide rail and reduce the accuracy of the measurement data.

[0006] Furthermore, in existing technologies, the size of the slider is relatively fixed, which in turn makes the mass of the slider relatively fixed. However, different types of riot control bullets have different sizes and masses. In order to more realistically simulate different types of riot control bullets, the slider often needs to be changed during training. However, existing training devices require steps such as disassembling screws to change the slider, which is a relatively complicated process. Therefore, it is necessary to design a slider that can quickly change its mass. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, the present invention aims to provide a slider assembly for a riot control grenade throwing auxiliary training device, so as to solve the problem that the riot control grenade training model generates a downward force on the slider under the action of gravity, which reduces the accuracy of measurement data in the prior art.

[0008] To address this, the present invention proposes a slider assembly for an auxiliary training device for throwing riot control grenades, comprising a pair of sliders and a connecting bracket connecting the two. The front end of the connecting bracket is fixedly connected to a riot control grenades model via an external traction rope. The sliders have cylindrical sliding guide grooves inside, which cooperate with the slide rail.

[0009] The connecting bracket is a hollow bracket, including an X-shaped connecting plate and a cylindrical body located in the middle. The cylindrical body is equipped with an automatic retraction mechanism for the traction rope. The automatic retraction mechanism for the traction rope includes an outer traction rope, a stop block, an inner traction rope, and a spiral spring connected in sequence, and also includes a perforated plug, a limiting ball, and a U-shaped baffle. The outer traction rope is Y-shaped, and the two ropes at the outer ends of the outer traction rope are respectively connected to the left and right ends of the connecting column in the riot control bomb model. The stop block is located inside the perforated plug to limit the maximum extension length of the outer traction rope. The limiting ball and the U-shaped baffle are located outside the perforated plug to temporarily control the extension of the outer traction rope by a certain distance. The spiral spring retracts the inner traction rope, so that the riot control bomb model and the slider assembly fit together and move synchronously.

[0010] Furthermore, the limiting ball is fixed to the outer traction rope, and the U-shaped baffle is a movable part, disposed between the limiting ball and the perforated plug.

[0011] Furthermore, the diameter of the limiting ball is smaller than the diameter of the through hole in the perforated plug, while the size of the inner groove in the U-shaped baffle is smaller than the diameter of the limiting ball, and the outer size of the U-shaped baffle is larger than the diameter of the through hole in the perforated plug.

[0012] Furthermore, the inner side of the sliding guide groove is provided with several support columns, the outer end of the support column is rotatably connected to an auxiliary wheel, the auxiliary wheel cooperates with the side of the slide rail, and the inner end of the support column is fixedly connected to a support spring.

[0013] Furthermore, a limiting bushing is provided on the outer side of the support column to slide with it, and the outer circle of the limiting bushing is interference-fitted with the slider.

[0014] Furthermore, the limiting bushing is provided with a waist-shaped hole, the support column is provided with a clearance notch that matches the waist-shaped hole, and the rear end of the support column is also provided with a limiting boss.

[0015] Furthermore, the bottom of the slider is provided with an electromagnet sleeve that runs through the front and back.

[0016] Furthermore, counterweight box mounting cavities are respectively provided on the left and right sides of the slider, and a counterweight box is snapped into each counterweight box mounting cavity; a pair of counterweight boxes are symmetrically distributed about the center of the slider, and the weight of the pair of counterweight boxes is always consistent.

[0017] Furthermore, each of the counterweight boxes has several mounting posts fixedly connected inside, and counterweight rings can be fitted onto the mounting posts.

[0018] Furthermore, each of the mounting columns is fixedly connected to a limit buckle, which is arc-shaped.

[0019] The slider assembly of the anti-riot grenade throwing auxiliary training device provided by the present invention has an automatic retraction mechanism for the traction rope connected to the anti-riot grenade model. After the anti-riot grenade model is thrown, the spiral spring drives the traction rope to retract, and the anti-riot grenade model moves towards the slider assembly with the outer traction rope, so that the two are integrated. This can prevent the anti-riot grenade model from exerting a downward force on the slider assembly under the action of gravity after moving forward a certain distance, thereby improving the accuracy of the measurement data.

[0020] Furthermore, the slider assembly provided by this invention can overcome the problem of the slider easily getting stuck when moving to the curved guide rail by setting a support column with an auxiliary wheel and a support spring on the inner side of the sliding guide groove; by setting a counterweight box with a mounting column and a counterweight ring, the overall weight of the slider can be quickly changed by adding or removing the counterweight ring, thereby more realistically simulating the throwing assistance training of different types of riot control munitions.

[0021] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, this invention discloses a riot control grenade throwing auxiliary training device, including two supports 1 with different heights. A pair of slide rails 3 are installed between the two supports 1. The slide rails 3 are arranged parallel to each other and are configured in a "J" shape. The slide rails 3 are installed at an inclination between the two supports 1, and the inclination angle b between the inclined straight section of the slide rail 3 and the ground is 30 to 45 degrees. A slider assembly 4 is sleeved on the slide rail 3 and is slidably connected to the slide rail 3. The front end of the slider assembly 4 is connected to a riot control grenade training model through a traction rope.

[0034] The aforementioned training device uses a traction rope to flexibly connect the slider assembly and the riot control grenade training model. On the one hand, the training model can drive the slider assembly to move, more realistically simulating the throwing action of the riot control grenade, while using the riot control grenade model provides a realistic sense of control. On the other hand, the traction rope has a certain length, which allows for a non-rigid connection between the training model and the slider assembly, providing some room for movement. This means that the throwing action of the trainees is not exactly the same, but it is more adaptable to individual differences in human anatomy and is more in line with the laws of human kinematics. In addition, using a traction rope can prevent the slider assembly from hitting the back of the trainee's hand during training, reducing training injuries.

[0035] like Figures 2-7As shown, the slider assembly 4 includes a pair of sliders 40 and a connecting bracket 46 connected between them. The front end of the connecting bracket 46 is fixedly connected to the anti-riot bullet model 6 by an external traction rope 465. The slider 40 has a cylindrical sliding guide groove 43 that runs through it from front to back. The slider 40 is sleeved on the slide rail 3 through the sliding guide groove 43. The diameter of the sliding guide groove 43 is larger than the diameter of the slide rail 3.

[0036] To improve the stability of the slide rail 3, the connecting rod between the slide rail 3 and the bracket 1 is not located at the end of the slide rail 3, which may prevent the connecting rod from blocking the movement of the slider 40. Therefore, a clearance notch 41 is provided at the upper end of the slider 40. The clearance notch 41 is used to avoid the connecting rod connected to the slide rail 3, so that the slider assembly 4 can move along the slide rail 3 while ensuring the installation and fixation of the slide rail 3.

[0037] like Figures 2-5 As shown, the connecting bracket 46 is a hollow bracket, including a cylindrical body 461 in the middle, horizontal connecting plates at the upper and lower ends, and an X-shaped connecting plate. The plates are connected by welding.

[0038] Among them, such as Figure 4 As shown, the cylindrical body 461 is provided with an automatic traction rope retraction mechanism. The automatic traction rope retraction mechanism includes an outer traction rope 465, a stop block 463, an inner traction rope 468 and a spiral spring 464 connected in sequence. The automatic traction rope retraction mechanism also includes a plug with a hole 462, a limiting ball 466 and a U-shaped baffle 467.

[0039] The external traction rope 465 is configured in a Y shape, and the two ropes at the outer end of the external traction rope 465 are respectively connected to the left and right ends of the connecting column in the riot control bullet model 6, so that the force on the riot control bullet model 6 and the slider assembly in the left and right directions is more balanced.

[0040] The stop block 463 is located inside the cavity of the cylindrical body 461, while the perforated plug 462 is installed at the front end of the cylindrical body 461 by a threaded connection. The perforated plug 462 restricts the stop block 463 from moving to the outside of the cylindrical body 461, thereby limiting the maximum length of the external traction rope 465. The limiting ball 466 is fixed at a certain position on the side of the external traction rope 465 near the stop block 463. The U-shaped baffle 467 is a movable part, which is set between the limiting ball 466 and the perforated plug 462 to restrict the external traction rope 465 from moving into the cylindrical body 461 under the action of the spiral spring 464.

[0041] Among them, such as Figure 5 As shown, the diameter of the limiting ball 466 is smaller than the diameter of the through hole in the perforated plug 462, while the size of the inner groove in the U-shaped baffle 467 is smaller than the diameter of the limiting ball 466, and the outer size of the U-shaped baffle 467 is larger than the diameter of the through hole in the perforated plug 462, thus playing a limiting role.

[0042] During the training preparation phase, trainees pull the riot control bullet model 6 forcefully, causing the limiting ball 466 to move from inside the cavity of the cylindrical body 461 to the outside. Then, it is blocked by the U-shaped baffle 467 to prevent the limiting ball 466 and the outer traction rope 465 from retracting back into the cavity of the cylindrical body 461, thus playing a limiting role.

[0043] When the trainees are ready to complete the training, the riot control bullet model 6 is thrown forward. The riot control bullet model 6 moves the entire slider assembly 4 along the slide rail 3 by the external traction rope 465. During the throwing process, the perforated plug 462 and the stop block 463 limit the maximum length of the external traction rope 465. At the moment of throwing, the external traction rope 465 is subjected to force, and the U-shaped baffle 467 falls off between the limiting ball 466 and the perforated plug 462, allowing the limiting ball 466 to pass through the round hole in the middle of the perforated plug 462. The external traction rope 465, the stop block 463 and the internal traction rope 468 retract into the cavity of the cylindrical body 461 under the action of the spiral spring 464. At the same time, the riot control bullet model 6 moves towards the slider assembly 4 with the external traction rope 465, so that the two are integrated. This can prevent the riot control bullet model 6 from moving backward under the action of gravity after moving forward a certain distance, which would generate a downward force on the slider assembly 4 and improve the accuracy of the measurement data.

[0044] like Figure 3 , Figure 7 As shown, the slider 40 has several support columns 42 slidably connected inside. Each support column 42 has a support spring 44 fixedly connected to one end inside the slider 40, and an auxiliary wheel 411 rotatably connected to the other end outside the slider 40. The auxiliary wheel 411 contacts the slide rail 3. By setting the auxiliary wheel 411, the sliding friction between the slider 40 and the slide rail 3 can be transformed into rolling friction, reducing the coefficient of friction and obtaining more accurate experimental data. By setting the support spring 44, the auxiliary wheel 411 can be kept close to the slide rail 3 and has a buffer space, reducing the possibility of jamming during the movement of the slider 40.

[0045] The support column 42 is provided with a limiting sleeve 412 that slides with it, and the outer circle of the limiting sleeve 412 is interference-fitted with the slider 40. The limiting sleeve 412 has a waist-shaped hole, and the support column 42 has a clearance notch that matches the waist-shaped hole, ensuring that the circumferential position of the support column 42 remains unchanged when sliding with the limiting sleeve 412, thus ensuring that the direction of the auxiliary wheel 411 is always consistent with the axis of the slide rail 3. Furthermore, the rear end of the support column 42 has a limiting boss, making the cross-sectional dimension of the rear end of the support column 42 larger than the dimension of the limiting sleeve 412, thereby providing axial limiting for the support column 42.

[0046] like Figure 3As shown, the slider 40 has counterweight box mounting cavities on its left and right sides, and a counterweight box 47 is snapped into each counterweight box mounting cavity. The ends of the two counterweight boxes 47 that are close to each other are symmetrically fixedly connected with locking blocks 413. The counterweight box mounting cavity of the slider 40 is provided with a slot corresponding to the locking block 413. The counterweight box 47 is fixedly connected with several mounting posts 48.

[0047] like Figure 6 As shown, each of the mounting posts 48 has a fixed limit buckle 410 on its outer wall. The limit buckle 410 is arc-shaped, and each of the mounting posts 48 is fitted with a counterweight ring 49. The overall weight of the slider 40 can be changed by increasing or decreasing the counterweight ring 49.

[0048] Furthermore, the bottom of the slider 40 is equipped with an electromagnet sleeve 45 that extends from front to back. The lower end of the slide rail 3 is fixedly connected to a copper tube 5, and the electromagnet sleeve 45 is fitted over the copper tube 5. During use, when the slider hits the force sensor, the electromagnet sleeve will be energized. At this time, the slider will experience electromagnetic resistance as it slides down the slide rail, thereby slowing down its descent speed and preventing it from hitting the trainee due to excessive speed. This greatly increases the safety and reliability of the invention.

[0049] like Figure 1 As shown, the slide rail 3 includes a straight track and an arc track. Setting one end of the slide rail 3 as an arc track makes the invention more compatible with throwing motions during use, thereby allowing trainees to form muscle memory and make their throwing motions more accurate. The straight track and the arc track are integrally formed, and the arc track is located at the rear end of the straight track.

[0050] A speed sensor and a high-speed camera are installed on the inner wall of the bracket 1 near one end of the curved track of the slide rail 3. A force measuring device is also fixedly connected to the upper end of the slide rail 3. In use, the slider slides along the straight track and eventually hits the force measuring device. The force measuring device then measures the impact force of the slider. In this way, it is possible to indirectly determine whether the trainee's throwing force is sufficient. Moreover, the speed sensor and the high-speed camera can record the speed of the slider and the image of the throw, which facilitates subsequent analysis and summarization of the throwing motion and force application method.

[0051] The working principle and process of the slider assembly of the anti-riot grenade throwing auxiliary training device of the present invention are briefly described below with reference to the accompanying drawings.

[0052] When using this invention, the trainee first pulls the anti-riot bullet model 6 with force, causing the limiting ball 466 to move from the cavity of the cylindrical body 461 to the outside. Then, it is blocked by the U-shaped baffle 467 to prevent the limiting ball 466 and the outer traction rope 465 from retracting back into the cavity of the cylindrical body 461.

[0053] Trainees can stand below the support 1, hold the riot control bomb model 6 in their hands, and then make a throwing motion. When the trainee makes the throwing motion, the slider component 4 is located in front of the slide rail 3 (there is a standard motion for training throwing. When making the standard motion, the arm holding the riot control bomb model 6 is behind the head and lower than the head. When the trainee throws the riot control bomb model 6, the arm swings and draws an arc segment). After holding the riot control bomb model 6, prepare to exert force and then swing the arm to throw the riot control bomb model 6.

[0054] When the riot control bomb model 6 is thrown, the slider 40 just finishes sliding on the arc track. After being thrown, the riot control bomb model 6 will slide along the straight track with the slider 40. At the moment of projection, the outer traction rope 465 is stressed, and the U-shaped baffle 467 falls off between the limiting ball 466 and the perforated plug 462, allowing the limiting ball 466 to pass through the round hole in the middle of the perforated plug 462. The outer traction rope 465, the baffle 463, and the inner traction rope 468 retract into the cavity of the cylindrical body 461 under the action of the spiral spring 464. At the same time, the riot control bomb model 6 moves towards the slider assembly 4 with the outer traction rope 465, making the two a single unit. This prevents the riot control bomb model 6 from moving forward a certain distance and then moving backward under the action of gravity, which would exert a downward force on the slider assembly 4 and affect the accuracy of the measurement data.

[0055] Slider 40 slides along a straight track and eventually hits the force measuring device. The force measuring device then measures the impact force of slider 40. In this way, it can be indirectly determined whether the trainee's throwing force is sufficient (the greater the throwing force, the greater the force of slider 40 hitting the force measuring device, and vice versa). In addition, the speed sensor and high-speed camera can record the speed of slider 40 and the throwing image, which can facilitate subsequent analysis and summary of the throwing motion and force application method.

[0056] When the slider 40 hits the force measuring device, the electromagnet sleeve 45 will be energized. At this time, when the slider 40 slides down the slide rail 3, it will be subject to electromagnetic resistance, which will slow down the sliding speed and prevent the slider 40 from sliding down too fast and hitting the trainee. This method greatly increases the safety and reliability of the invention.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
