Description

Technical Field

[0001] This utility model belongs to the field of sports equipment, and in particular relates to a horizontal push-pull frame and a judo horizontal push-pull training device. Background Technology

[0002] The "horizontal push" and "horizontal pull" movements in the standing position are commonly used in judo. The strength of the "horizontal push" and "horizontal pull" is also one of the key factors that determine the outcome of the competition. However, there is currently a lack of corresponding training equipment, making it difficult for athletes to train alone. Usually, two athletes need to cooperate to practice together, but this will affect the training effect and flexibility. Even when training alone, dumbbells or barbells are mostly used. Although they can train the athlete's arm strength and chest muscles, their simulation effect is not good and they do not play a significant role in improving the athlete's skills and tactics. Utility Model Content

[0003] To solve the above-mentioned technical problems, one of the objectives of this utility model is to provide a horizontal push-pull bracket with a simple structure that can provide a margin for forward and backward pushing and pulling and adjustable resistance.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A horizontal push-pull frame includes a side frame, a sliding seat, a sliding block, a resistance adjusting component, and a push-pull rod. The side frame is vertically arranged in the front-back direction, the sliding seat is vertically arranged in the front-back direction and installed on the side frame, the sliding block is slidably installed on the sliding seat, the push-pull rod is horizontally arranged in the left-right direction and connected to the sliding block, and the push-pull rod drives the sliding block to slide back and forth on the sliding seat under the action of external force. The resistance adjusting component is installed on the sliding seat, and its driving end is connected to the sliding block in a transmission connection. The resistance adjusting component is used to adjust the resistance of the sliding block sliding back and forth on the sliding seat.

[0005] The beneficial effects of the above technical solution are as follows: it allows judo athletes to push and pull the push-pull rod horizontally in the front-back direction. At this time, the resistance adjustment component provides sliding resistance to the sliding block, thereby enabling judo athletes to perform "horizontal push" or "horizontal pull" action training under resistance conditions. The simulation effect is good and it is closer to the actual combat action.

[0006] In the above technical solution, the height of the sliding seat on the side stand is adjustable.

[0007] The beneficial effect of the above technical solution is that by adjusting the height of the sliding seat on the side stand, it can meet the training needs of people of different heights.

[0008] In the above technical solution, the side support has a through mounting hole in the middle. The sliding seat is placed in the mounting hole, and the front and rear ends of the sliding seat are slidably connected to the side support. The front and rear ends of the side support are provided with multiple through first pin holes at vertical intervals along the sliding trajectory of the sliding seat. The front and rear ends of the sliding seat are provided with through second pin holes. The sliding seat slides vertically in the mounting hole until each second pin hole aligns with any one of the first pin holes on the corresponding side, and a pin is inserted to limit the sliding seat to any height position on its sliding trajectory.

[0009] The advantages of the above technical solution are: its structure is simple, which allows the entire sliding seat to have multiple positions on the side stand for height selection via a pin.

[0010] The above technical solution also includes a counterweight, a sling, and two fixed pulleys. The counterweight is slidably installed on the rear side of the side support. Both fixed pulleys are installed on the upper end of the side support. One fixed pulley is located in the middle of the upper end of the side support, and the other fixed pulley is located on the rear side of the upper end of the side support. One end of the sling is connected to the middle of the upper end of the sliding seat, and the other end passes around the two fixed pulleys and is connected to the counterweight.

[0011] The beneficial effects of the above technical solution are as follows: by setting a counterweight to lift the sliding seat, the sliding seat is more convenient and flexible when adjusting up and down, and when the sliding seat is disconnected from the side frame, the sliding seat will not fall down under the action of gravity and cause injury.

[0012] The resistance adjusting component in the above technical solution includes a resistance motor, a drive cable, and two grooved wheels. The sliding seat has through holes at both ends. The two grooved wheels are horizontally arranged and rotatably installed in the two through holes. The resistance motor is installed on the sliding seat with its drive end facing up or down. A winding grooved wheel is coaxially fixed on the drive end of the resistance motor. The middle part of the drive cable is wound around the winding grooved wheel multiple times. The two ends of the drive cable pass around the two grooved wheels and are connected to the corresponding side of the sliding block. The sliding block overcomes the resistance of the resistance motor and slides back and forth under the action of external force.

[0013] The beneficial effect of the above technical solution is that the sliding block overcomes the resistance of the resistance motor when it moves back and forth and is driven by the drive cable to rotate the resistance motor, and the resistance applied by the resistance motor can be adjusted as needed.

[0014] In the above technical solution, the push-pull rod is located on the side of the sliding block away from the resistance motor.

[0015] The beneficial effect of the above technical solution is that it allows the push-pull rod to avoid the resistance motor and its forward and backward movement to be greater.

[0016] The second objective of this invention is to provide a judo horizontal push-pull training device with a simple structure that allows judo athletes to perform horizontal push-pull movements under resistance conditions.

[0017] To achieve the above objectives, another technical solution of this utility model is as follows: a judo horizontal push-pull training device, comprising two horizontal push-pull frames as described above, the two horizontal push-pull frames being symmetrically arranged in the left-right direction, and the two push-pull rods extending to be connected to each other and integrally formed.

[0018] The beneficial effects of the above technical solution are: it makes the impedance effect at both ends of the push-pull rod consistent and makes the stability of the entire judo horizontal push-pull training device better.

[0019] The above technical solution also includes multiple connecting rods arranged horizontally in the left-right direction. The multiple connecting rods are arranged on the rear side and the top of the two side supports, and the two ends of each connecting rod are respectively connected to the two side supports.

[0020] The beneficial effect of the above technical solution is that it makes the structural strength of the entire judo horizontal push-pull training device better.

[0021] In the above technical solution, one of the connecting rods is located at the upper front end of the two side supports.

[0022] The beneficial effect of the above technical solution is that it allows trainees to perform pull-up training using the connecting rods at the upper front of the two side stands.

[0023] The above technical solution also includes a controller, and both of the resistance adjustment components are electrically connected to the controller.

[0024] The beneficial effect of the above technical solution is that the resistance of the resistance adjustment component can be adjusted by the controller. Attached Figure Description

[0033] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0034] like Figure 1As shown, this embodiment provides a horizontal push-pull bracket, including a side support 11, a sliding seat 12, a sliding block 13, a resistance adjusting component 14, and a push-pull rod 15. The side support 11 is vertically arranged in the front-to-back direction, the sliding seat 12 is vertically arranged in the front-to-back direction and mounted on the side support 11, the sliding block 13 is slidably mounted on the sliding seat 12, and the push-pull rod 15 is horizontally arranged in the left-to-right direction and connected to the sliding block 13. Under the action of external force, the push-pull rod 15 drives the sliding block 13 forward and backward on the sliding seat 12. After sliding, the resistance adjustment component 14 is installed on the sliding seat 12, and its driving end is connected to the sliding block 13. The resistance adjustment component 14 is used to adjust the resistance of the sliding block 13 sliding back and forth on the sliding seat 12. This allows the judo athlete to push and pull the push-pull rod horizontally in the front and back directions. At this time, the resistance adjustment component provides resistance to the sliding block, so that the judo athlete can perform "horizontal push" or "horizontal pull" action training under resistance conditions. The simulation effect is good and it is closer to the actual combat action.

[0035] like Figure 1 and Figure 2 As shown, in the above technical solution, the height of the sliding seat 12 on the side stand 11 is adjustable. By adjusting the height of the sliding seat on the side stand, it can meet the training needs of people of different heights. Specifically, the side stand 11 is a hollow frame with a through mounting hole 111 in its middle. The sliding seat 12 is placed in the mounting hole 111, and the front and rear ends of the sliding seat 12 are slidably connected to the side stand 11. The front and rear ends of the side stand 11 are vertically spaced along the sliding trajectory of the sliding seat 12. The sliding seat 12 has multiple through first pin holes 112 and through second pin holes 121 at both ends. The sliding seat 12 slides vertically within the mounting hole 111 until each second pin hole 121 aligns with any one of the first pin holes 112 on the corresponding side, and a pin 16 is inserted to limit the sliding seat 12 to any height position on its sliding trajectory (the pin can be a steel ball pin). Its structure is simple, so that the entire sliding seat can have multiple stops on the side stand for height selection by means of pins.

[0036] like Figure 1 and Figure 2As shown, the above technical solution also includes a counterweight 17, a sling 18, and two fixed pulleys 19. The counterweight 17 is slidably installed on the rear side of the side support 11. Both fixed pulleys 19 are installed on the upper end of the side support 11. One fixed pulley 19 is located in the middle of the upper end of the side support 11, and the other fixed pulley 19 is located on the rear side of the upper end of the side support 11. One end of the sling 18 is connected to the middle of the upper end of the sliding seat 12, and the other end passes around the two fixed pulleys 19 and is connected to the counterweight 17. By setting the counterweight, the sliding seat can be lifted, which makes the sliding seat easier and more flexible to adjust up and down. When the sliding seat is disconnected from the side support, the sliding seat will not fall under the action of gravity and cause injury.

[0037] like Figure 3 - Figure 6 As shown, the resistance adjusting component 14 in the above technical solution includes a resistance motor 141, a drive cable 142, and two grooved pulleys 143. The sliding seat 12 has through holes 122 at both its front and rear ends. The two grooved pulleys 143 are horizontally arranged and rotatably installed within the two through holes 122. The resistance motor 141 is mounted on the sliding seat 12, with its drive end facing upwards or downwards. A cable winding grooved pulley 144 is coaxially fixed to the drive end of the resistance motor 141. The middle portion of the drive cable 142 is wound multiple times (2-5 turns) around the cable winding grooved pulley 144. The drive cable 142 is preferably wound around the grooved reel 143 3 times. Both ends of the drive cable 142 pass over the two grooved reels 143 respectively and connect to the corresponding sides of the sliding block 13 (while ensuring the drive cable is taut). Under external force, the sliding block 13 overcomes the resistance of the resistance motor 141 and slides back and forth. This allows the sliding block to overcome the resistance of the resistance motor as it moves back and forth, and the drive cable drives the resistance motor to rotate. The resistance applied by the resistance motor can be adjusted as needed (the drive cable constitutes the drive end of the resistance adjustment component). Alternatively, a magnetic powder damper can be used as the resistance motor (both serve similar functions).

[0038] like Figure 1 - Figure 5 As shown, in the above technical solution, the push-pull rod 15 is located on the side of the sliding block 13 away from the resistance motor 141, so that the push-pull rod can avoid the resistance motor and its forward and backward movement is greater.

[0039] See details Figure 2 - Figure 5As shown, the side support frame in this embodiment includes two columns 113 and multiple crossbeams 114. The two columns 113 are vertically arranged and spaced apart in the front-to-back direction. The multiple crossbeams 114 are horizontally arranged between the two columns 113 in the front-to-back direction, and are vertically spaced apart between the two columns 113. Each crossbeam 114 is connected to two columns 113 at both ends. First pin holes are provided on the columns 113. The holes formed by two adjacent crossbeams 114 and two columns 113 constitute the mounting holes (located in the middle of the corresponding side support frame). First sliding rods 115 are vertically arranged at both ends of the mounting holes (the two ends of the first sliding rods 115 are connected to the corresponding two crossbeams 114). The sliding seat is a straight strip, with corresponding first sliding rods 115 at both ends. The sliding hole 124 is provided, and the first sliding rod 115 passes through the corresponding sliding hole 124, so that the sliding seat is vertically slidably connected to the side support. The front end and the rear end of the sliding seat are provided with U-shaped groove ears 123, and the groove openings of the groove ears 123 are opposite to each other and pass through vertically. Each groove ear 123 is for the corresponding end of the column 113 to be inserted, and the second pin hole is provided on the groove ear 123 (the second pin hole is a pair of holes provided on the groove walls on both sides of the groove ear 123, that is, two holes aligned with each other constitute the second pin hole). Specifically, the number of first pin holes on the two columns 113 is the same and they correspond one-to-one (the horizontal height of the two corresponding first pin holes is the same, and the horizontal height of the two second pin holes on the sliding seat is also the same, so that when the sliding seat moves up and down, its two second pin holes can be aligned with the corresponding two first pin holes at the same time to facilitate the insertion of a pin for pin connection and limit.

[0040] For details, please see Figure 3 - Figure 5 As shown, in this embodiment, the sliding seat can be a groove (similar to the structure of channel steel), with its groove opening facing one side, and the sliding block is slidably installed in its groove (the sliding block slides along its length direction in the groove of the sliding seat), while the resistance motor is installed in the middle of the other side of the sliding seat. This achieves a separation between the sliding seat and the resistance motor, and the installation position of the resistance motor will not affect the sliding of the sliding block.

[0041] like Figure 2 As shown, the second slide rod 116 is vertically installed on the rear side of the column located at the rear (the two ends of the second slide rod 116 are connected to the side support). The counterweight can be a cylindrical metal block (it can be an iron block or a lead block). The counterweight can be sleeved on the second slide rod 116. At this time, the second slide rod 116 can limit the counterweight and prevent the counterweight from shaking.

[0042] Example 2

[0043] like Figure 7 As shown, this embodiment provides a judo horizontal push-pull training device, including two horizontal push-pull frames 1 as described in Embodiment 1. The two horizontal push-pull frames 1 are symmetrically arranged in the left-right direction (the two side frames are parallel to each other and spaced apart in the left-right direction), and the two push-pull rods 15 extend to be connected to each other and integrally formed, so that the impedance effect at both ends of the push-pull rods is consistent and the stability of the entire judo horizontal push-pull training device is better.

[0044] The above technical solution also includes multiple connecting rods 2 arranged horizontally in the left-right direction. The multiple connecting rods 2 are arranged on the rear side and the top of the two side uprights 11. The two ends of each connecting rod 2 are connected to the two side uprights 11 respectively, which makes the structural strength of the entire judo horizontal push-pull training device better.

[0045] In the above technical solution, one of the connecting rods 2 is located at the upper front end of the two side stands 11 (the cross-section of the connecting rod is circular, which makes it comfortable to grip), so that the trainee can use the connecting rod at the upper front end of the two side stands to perform pull-up training.

[0046] The above technical solution also includes a controller 3, and both of the resistance adjustment components 14 are electrically connected to the controller 3, so that the controller can adjust the resistance of the resistance adjustment components.

[0047] In this embodiment, multiple connecting rods and two side supports are connected together to form a hollow frame, and the lower ends of the side supports can be installed on the ground by expansion bolts (at this time, the front of the hollow frame is open).

[0048] Preferably, the controller can be a tablet computer, which can be installed at the rear between the two side supports, that is, on any of the connecting rods located at the rear (within the hollow frame body), and its display interface faces forward.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
