Description

Technical Field

[0001] The invention relates to the technical field of sports training equipment, in particular to a tug-of-war training simulator. Background Art

[0002] Tug of war is a traditional Chinese sport of teamwork and has developed into an international sport. During a tug-of-war competition, a mark is placed in the middle of the cable. The players of both teams stand on both sides of the cable and pull the cable against each other. The winning team is determined by the position of the mark. Usually, the players will train and simulate before the official tug-of-war competition to find the best force posture and training effect, laying the foundation for winning the competition.

[0003] However, due to the limitation of the number of people, venue and weight level, it is difficult to conduct actual combat training in the actual tug-of-war scene, which makes it impossible for the contestants to experience the real-life tug-of-war with their opponents and achieve the expected effect of personal training. At present, there are also some tug-of-war training machines, such as the Chinese patent with the patent number CN109350906A, named as an electric resistance tug-of-war machine, which includes a body shell, a control panel, a rope winding mechanism, a tug-of-war cable, a belt, a motor pulley, a resistance motor, etc., and uses an electric mechanical structure to pull back, realizing the function of simulating the opponent's strength during training; another example is the Chinese patent with the patent number CN220213803U, named as a tug-of-war machine, which has a take-up wheel on the base, one end of which is connected to the motor, and uses the rotation of the motor to tighten the cable to simulate the tug-of-war scene, which is used for sparring and improving the user's arm strength.

[0004] Although the above-disclosed prior art can replace the traditional pure manpower training mode at both ends of the cable, it still has the following defects during use: First, the existing equipment can only realize single-person training, and cannot carry out collective training of members; Second, the existing equipment uses a fixed resistance output by the motor, which makes it impossible to experience strength training of different weights when multiple people are training; Third, the existing equipment is not convenient for real-time adjustment of the intensity during training, and it is difficult for trainees to experience the sense of presence of competing with each other in real time. Summary of the invention

[0005] In order to solve the deficiencies in the above-mentioned prior art, the present invention proposes a tug-of-war training simulator, which uses a training chair to train the waist and abdomen strength of training members when their center of gravity is tilted backward. During the training process, the training members can change the force acting on the tension rope in real time (simulating the mutual pulling and counteracting of the load force applied to the tension rope by the opponent) with the cooperation of the pulley group component and the variable force component, and can experience the training of different mechanical properties during the training process. The load component connected to the end of the tension rope is used in conjunction with a clamp to meet the simulation training needs of different weight classes. The device of the present invention replaces the complex reduction mechanism of the existing electric motor with mechanical transmission, has low transmission noise and saves cost, can meet the multi-mode training of variable force performance of multiple members, and can be promoted and applied in the market.

[0007] As a further preferred embodiment of the above scheme: the pulley block component includes a mounting frame, a first fixed pulley, a second fixed pulley and a movable pulley, wherein: The mounting frame is fixedly connected to the training base; The first fixed pulley is mounted on the upper end of the mounting frame away from the training chair; The second fixed pulley is installed at the lower end of the mounting frame and is located between the first fixed pulley and the movable pulley; The movable pulley is mounted on the upper end of the mounting frame close to one side of the training chair.

[0008] Based on the above technical solution, further, a limiting groove is provided on the mounting frame, and the movable pulley is movably connected in the limiting groove.

[0009] As a further preferred embodiment of the above scheme: the force changing member comprises a first inclined plate, a second inclined plate and a lifting rod, wherein: The first inclined plate is slidably connected to the training base, and a rack is provided on the inclined surface of the first inclined plate; The second inclined plate is fixedly connected to the first inclined plate, and the inclined surface of the second inclined plate is provided with anti-slip edges; The lifting rod is movably connected to the mounting frame, a third spring is sleeved on the lifting rod, and two ends of the third spring are respectively abutted against the lifting rod and the mounting frame.

[0010] Based on the above technical solution, further, the bottom of the lifting rod is connected to a roller, and the roller abuts against the first inclined plate.

[0011] As a further preferred embodiment of the above scheme: the training chair comprises a seat frame and legs connected to the bottom thereof, wherein: The seat frame is L-shaped, comprising a supporting seat plate and a backrest plate, wherein the backrest plate is hinged to the supporting seat plate; The two ends of the supporting leg are movably connected to the supporting seat plate and the training base respectively, a first spring is sleeved on the supporting leg, and the two ends of the first spring are fixedly connected to the supporting seat plate and the training base respectively.

[0012] Based on the above technical solution, further, a support assembly is provided on one side of the training chair, and the support assembly includes: A support plate connected to the bottom of the support base plate; The support rod is movably connected to the backrest plate, and the support rod is slidably matched with the supporting plate.

[0013] Based on the above technical solution, further, a slide groove is provided on the support plate, a slider is connected in the slide groove via a second spring, and both ends of the support rod are hinged to the backrest plate and the slider respectively.

[0014] As a further preferred embodiment of the above scheme: the load member includes a plurality of weights and a clamp, wherein: A plurality of weights are inserted into the limit posts on the training base; The clamp is inserted into the clamping holes on both sides of the weight, and the load adjustment of the tension rope is achieved by connecting the Mafas in different positions through the clamp.

[0015] The present invention also provides a tug-of-war training method using a tug-of-war training simulator, comprising the following steps: a. The trainer sits on the training chair and holds the tension rope tightly with both hands; b. The trainee pushes the first inclined plate by stepping on the second inclined plate, and the first inclined plate pushes the roller to move upward along the rack. At the same time, the lifting rod pushes the movable pulley to move upward along the limit groove, and the impedance force on the tension rope increases, allowing the trainee to experience the counterbalancing force in a real scene; c. Use the clamp to adjust the number of weights to perform different weight training. After the training, push the third inclined plate to reset the first inclined plate and the second inclined plate synchronously.

[0016] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: 1. The present invention arranges a training chair on a training base, and the two ends of the legs are movably connected to the seat frame and the training base respectively, so that when the trainees are doing simulation training, the training chair can swing flexibly following the posture of the trainees, and will not cause any restrictions or influences on the training results. The support assembly is connected to the rear side of the training chair, and the backrest plate cooperates with the support assembly. When the trainees pull the tension rope to lean backward, the support rod, the slider and the second spring cooperate to support the lower limbs, and at the same time, the waist and abdomen strength is trained, which is conducive to the trainees finding a suitable force posture during the training process and improving the training effect.

[0017] 2. By arranging the pulley group component to cooperate with the variable force component, the trainee steps on the first inclined plate during training. When the first inclined plate moves forward, the friction of the rack on it on the roller is used to make the roller roll from bottom to top along the inclined surface of the first inclined plate. At this time, the lifting rod moves upward and pushes the movable pulley to move upward along the limit groove. The movement of the movable pulley changes the balance force of the original equilateral triangle, so that the length of the tension rope on both sides of the movable pulley increases. At this time, the trainee needs to exert greater force to pull the tension rope. This process effectively simulates the real-time changing state of the two sides in the formal tug-of-war competition, making the training process more real. The variable force component is used to achieve training of different mechanical properties without changing the load counterweight, which is conducive to the trainee to find the best competition state through training.

[0018] 3. By setting a load component, the upper clamping block and the lower clamping block are respectively inserted into the openings on both sides of the weight to achieve weight adjustment, and the fourth spring between the upper clamping block and the lower clamping block is used to adjust the number of weights under different needs. The structure of the clamp is simple and the adjustment method is convenient, which can meet the adjustment needs under different weight training modes. BRIEF DESCRIPTION OF THE DRAWINGS

Example 1

[0023] like Figure 1-5 , Fig.13As shown, the present invention is a tug-of-war training simulator, comprising a training base 1, on which a training chair 2, a pulley block member 3, a variable force member 4 and a load member 5 are arranged. The training base 1 is L-shaped, and comprises a horizontal platform 11 and a vertical platform 12. The training chair 2 is movably connected to the horizontal platform 11, the pulley block member 3 is installed on the vertical platform 12 and is located on one side of the training chair 2, a tension rope 6 is wound around the pulley block member 3, and the pulley block member 3 is at a set distance from the training chair 2, so that the trainee can perform tug-of-war training within this distance, the variable force member 4 is movably connected to the horizontal platform 11 and cooperates with the pulley block member 3, and the force of the tension rope 6 is adjusted by the variable force member 4, the load member 5 is located on the side of the pulley block member 3 away from the training chair 2, and the end of the tension rope 6 is connected to the load member 5; when the present application is actually used (refer to Fig.13 ), the number of training chairs 2 is specifically set according to training needs. The one training chair 2 shown in the accompanying drawings is only for illustrating the structure and orientation of the training chair 2, and is not intended to limit the number of training chairs 2.

[0024] Specifically, two clamping plates 9 are fixedly connected to the vertical platform 12. The cross-section of the clamping plates 9 is semi-cylindrical, and the arc surfaces of the two clamping plates 9 are arranged close to each other. A gap is left between the two clamping plates 9. Two fixed plates (not shown in the figure) are connected between the two clamping plates 9. The tension rope 6 passes through the gap between the two fixed plates, which plays a limiting role on the tension rope 6 during training.

[0025] like Figure 4-5 As shown, the training chair 2 includes a seat frame 21 and a leg 22. The seat frame 21 is an L-shaped structure including a supporting seat plate 211 and a backrest plate 212, and the backrest plate 212 is hinged at the edge of the supporting seat plate 211. There are two legs 22, and the two ends of the legs 22 are respectively movably connected to the supporting seat plate 211 and the horizontal platform plate 11; in this embodiment, both ends of the legs 22 are spherical, and the horizontal platform plate 11 and the supporting seat plate 211 are respectively provided with a first ball joint seat and a second ball joint seat, and the lower end and the upper end of the leg 22 are respectively matched with the first ball joint seat and the second ball joint seat, so that the training chair 2 can rotate in any direction relative to the horizontal platform plate 11.

[0026] Furthermore, a first spring 23 is sleeved on the support leg 22, the upper end of the first spring 23 is fixedly connected to the bottom of the support seat plate 211, and the lower end of the first spring 23 is fixedly connected to the top of the horizontal platform 11. Under the elastic buffering effect of the first spring 23, the training chair 2 moves synchronously with the swinging posture of the trainee, thereby assisting the trainee in leg strength training.

[0027] like Figure 4The support plate 71 is fixedly mounted on the bottom of the support seat plate 211 and extends backward. One end of the support rod 72 is movably mounted on the backrest plate 212, and the other end thereof is slidably matched with the support plate 71. Specifically, a slide groove 711 is provided in the middle of the support plate 71, and a slider 74 is provided in the slide groove 711. The slider 74 is connected to the inner wall of the slide groove 711 through a second spring 73. The upper end of the support rod 72 is hinged to the backrest plate 212, and the lower end of the support rod 72 is hinged to the slider 74. When the trainee sits on the training chair 2 for tug-of-war training, his body leans against the backrest plate 212 and tilts backward to exert force. At this time, the backrest plate 212 rotates backward under the cooperation of the support rod 72, the slider 74 and the support plate 71, which can effectively exercise the waist and abdomen strength while supporting the lower limbs of the trainee. Example 2

[0028] On the basis of the above-mentioned embodiment 1, in order to achieve a better tug-of-war training effect for the trainees, the pulley block component 3 and the variable force component 4 are further improved as follows: like Figure 6-7 As shown, the pulley block member 3 includes a mounting frame 31, a first fixed pulley 32, a second fixed pulley 33 and a movable pulley 34, the mounting frame 31 is fixedly connected to the vertical table 12, and the mounting frame 31 is used to arrange the first fixed pulley 32, the second fixed pulley 33 and the movable pulley 34, wherein: the first fixed pulley 32 is mounted on the upper end of the mounting frame 31 away from the training chair 2, the movable pulley 34 is mounted on the upper end of the mounting frame 31 close to the training chair 2, the second fixed pulley 33 is mounted on the lower end of the mounting frame 31, and the second fixed pulley 33 is located between the first fixed pulley 32 and the movable pulley 34, and the original positions of the first fixed pulley 32, the second fixed pulley 33 and the movable pulley 34 form an equilateral triangle, and the tension rope 6 is sequentially wound around the first fixed pulley 32, the second fixed pulley 33 and the movable pulley 34, and its free end extends to the training chair 2 and passes through the training chair, and the other end of the tension rope 6 is connected to the load member 5; Furthermore, the first fixed pulley 32 and the second fixed pulley 33 are rotationally connected to their corresponding mounting shafts, the movable pulley 34 is fixedly connected to its mounting shaft, a limiting groove 311 is provided at the mounting frame 31 where the movable pulley 34 is provided, and the movable pulley 34 is movably connected in the limiting groove 311. Specifically, the mounting shaft of the movable pulley 34 is slidably connected in the limiting groove 311, so that the mounting shaft of the movable pulley 34 can rotate and slide up and down in the limiting groove 311.

[0029] like Figure 8-9As shown, the force variable component 4 includes a first inclined plate 41, a second inclined plate 42 and a lifting rod 43. The first inclined plate 41 is slidably connected to the training base 1. The first limit bar and the second limit bar are respectively connected to the bottom of the first inclined plate 41 and the side close to the vertical table 12, and the first limit bar and the second limit bar are respectively slidably matched with the first slide groove on the horizontal table 11 and the second slide groove on the vertical table 12. A rack 411 is provided on the inclined surface of the first inclined plate 41, the second inclined plate 42 is fixedly connected to the side of the first inclined plate 41 opposite to the rack 411, and the inclined surface of the second inclined plate 42 is provided with an anti-slip edge, and the side of the first inclined plate 41 away from the vertical table 12 is fixedly connected to the third inclined plate 46, and the first inclined plate 41 and the second inclined plate 42 are reset by pushing the third inclined plate 46. The lifting rod 43 is movably connected to the mounting frame 31, and the top of the lifting rod 43 abuts against the mounting shaft of the movable sliding wheel 34.

[0030] Furthermore, a third spring 44 is sleeved on the outside of the lifting rod 43 , and two ends of the third spring 44 abut against the lifting rod 43 and the mounting frame 31 respectively. The bottom of the lifting rod 43 is connected to a roller 45 , and the roller 45 abuts against the first inclined plate 41 .

[0031] When the trainee is conducting tug-of-war training, the trainee pushes the first inclined plate 41 away from the training chair 2 by stepping on the second inclined plate 42. At this time, the lifting rod 43 moves upward with the cooperation of the rack 411 and the roller 45. The top of the lifting rod 43 pushes the movable pulley 34 to move upward along the limiting groove 311. At this time, the force of the tension rope 6 bypassing the other side of the movable pulley 34 (i.e., the side close to the training chair 2) changes, which enables the trainee to experience the sense of presence of competing with the opponent during the training process without changing the load. Example 3

[0032] Based on the above-mentioned embodiments 1-2, in order to facilitate the training of trainees in various weight modes, the following further improvements are made to the load component 5 of the present application.

[0033] like Figure 10-12 As shown, the load component 5 includes a plurality of weights 51 and a clamp 52. The plurality of weights 51 are passed through the limiting columns 8 on the horizontal platform plate 11. In the present embodiment, there are two limiting columns 8. Both sides of the weights 51 are provided with a clamp 511. The clamp 52 is inserted into the clamp 511. The load adjustment of the tension rope 6 is achieved by connecting the Mafa 51 at different positions through the clamp 52.

[0034] Specifically, Fig.12As shown, the clamping device 52 includes an upper clamping block 521 and a lower clamping block 522, and the upper clamping block 521 and the lower clamping block 522 are connected by a fourth spring 523. The upper clamping block 521 is always connected to the topmost weight 51, and the weight of the lower clamping block 522 is adjusted according to the actual strength requirements of the training. The lower clamping block 522 is inserted into the corresponding clamping port 511 of the weight 51 with the cooperation of the fourth spring 523, so that strength training of various weight modes can be carried out during the training process. Example 4

[0035] The tug-of-war training simulator provided by the present invention can be used for single-person training or multi-person training. When used specifically: First, the trainee sits on the training chair 2, holds the free ends of the tension rope 6 with both hands one in front and one behind, and the coach sets the training intensity according to the needs of the competition and the number of people, and adjusts the number of weights 51 lifted by the tension rope 6 through the clamp 52 to set the training intensity; Then, when you start training, you can train in the following two modes: ① Constant force training: The trainee steps on the horizontal platform 11 and uses the body's center of gravity to lean backward to squeeze the backrest board 212, and the backrest board 212 rotates backward. With the help of the cooperation between the support rod 72 and the slider 74 in the slide groove 711, the trainee's leg force and waist and abdomen strength can be exercised at the same time. In this process, the movable pulley 34 does not change position, and the training force is always the load gravity of the weight 51 at the other end of the tension rope 6; ② Variable force training: Under the condition of the same weight 51 as in ①, the trainee steps on the second inclined board 42 and uses the body's center of gravity to tilt backward to squeeze the backrest board 212, and the backrest board 212 rotates backward, so as to exercise the trainee's leg and waist and abdomen strength at the same time. During the force application process, the second inclined board 42 pushes the first inclined board 41 to move forward, and under the cooperation of the rack 411 and the roller 45 on the first inclined board 41, the lifting rod 43 is pushed to move upward. At the same time, the top of the lifting rod 43 pushes the movable pulley 34 to move upward along the limiting groove 311, so that the tension ropes 6 on both sides of the movable pulley 34 become longer than before, and the impedance of the tension rope 6 increases. At this time, the trainee needs to apply a greater force to pull the tension rope 6. During this process, the third spring 44 will squeeze the lifting rod 43 downward during the training process, thereby competing with the trainee. This process allows the trainee to experience the force application process of the two sides competing in the actual tug-of-war game, and achieves a better training effect. Finally, the number of connected weights 51 is adjusted by using the clamp 52 to perform training in different weight modes. After the training, the first inclined plate 41 and the second inclined plate 42 can be reset by pushing the third inclined plate 46 .

[0036] It is worth mentioning that the purpose of the training chair 2 of the present invention is to strengthen the training of the waist and abdomen strength of the trainees, so that the trainees can find the best way to exert the waist and abdomen strength through training. The trainees sit on the seat frame 21 in a sitting manner, and their training posture is basically the same as the posture of the formal tug-of-war competition. The setting of the training chair 2 will not affect the normal training of the trainees.

[0037] The detailed description of the above embodiments is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the invention. Based on the embodiments in the present invention, it is only used to illustrate the technical solution of the present invention rather than to limit it.
