[0059] The present application provides a connection structure, which is used to make a first mounting member 100 and a second mounting member 200 detachably connected. The connection structure includes a first connection hole 101, a second connection hole and a connection member 300, wherein the first connection hole 101 further includes two sliding parts 1011 and two limiting parts 1012; the first connection hole 101 is penetrated on the first mounting member 100, the second connection hole is penetrated on the second mounting member 200 relative to the first connection hole 101, the connection member 300 is slidably disposed in the second connection hole, and the connection member 300 is used to extend into or extend out of the first connection hole. Connecting hole 101; two sliding parts 1011 are relatively arranged on the first mounting member 100, a first distance is set between the two sliding parts 1011, two limiting parts 1012 are relatively arranged between the two sliding parts 1011, a second distance is set between the two limiting parts 1012, the first distance is greater than the second distance, the two sliding parts 1011 and the two limiting parts 1012 are surrounded to form a clamping space, after the connecting member 300 cooperates to extend into the clamping space and rotates a preset angle, the clamping space is used to limit the connecting member 300 from continuing to rotate, and / or the clamping space is used to prevent the connecting member 300 from rotating in the reverse direction.

[0060] Reference Figure 1 and Figures 4 to 7 In some embodiments, one end of the first mounting member 100 is connected to a part of the trainer for transmission, and the other end of the first mounting member 100 is used for detachable connection with the second mounting member 200. One end of the second mounting member 200 is connected to another part of the trainer for transmission, and the other end of the second mounting member 200 is used for detachable connection with the first mounting member 100. When the connection between the first mounting member 100 and the second mounting member 200 is disconnected, the trainer is used for differential training. When the first mounting member 100 and the second mounting member 200 are connected through a connecting structure, the trainer is used for linkage training.

[0061] Reference Figure 1 and Figure 2In some embodiments, the first connection hole 101 is penetrated on the first mounting member 100, and the first connection hole 101 includes two sliding parts 1011 and two limiting parts 1012. The two sliding parts 1011 are configured as two arc-shaped parts with convex surfaces facing each other, and a first spacing is provided between the two sliding parts 1011, and the first spacing gradually increases from the two ends of the two sliding parts 1011 to the middle of the two ends; the two limiting parts 1012 are relatively arranged between the two sliding parts 1011, and a second spacing is provided between the two limiting parts 1012, and the second spacing is not greater than the maximum value of the first spacing, and the two limiting parts 1012 are configured as two relatively parallel straight line segments.

[0062] It should be noted that, based on the arc-shaped setting of the sliding part 1011, the first spacing between the two sliding parts 1011 is not a constant value. Depending on the measurement position, the first spacing includes a maximum value and a minimum value. When the measurement position is located at either end of the sliding part 1011, the first spacing takes the minimum value. When the measurement position is located at the center position between the two ends of the sliding part 1011, the first spacing takes the maximum value.

[0063] In some embodiments, the second connecting hole is penetrated on the second mounting member 200 relative to the first connecting hole 101, and a connecting member 300 is slidably arranged in the second connecting hole. The connecting member 300 is used to extend into or out of the first connecting hole 101, and the connecting member 300 further includes an extension portion 301 and a guide portion 302.

[0064] Reference Figure 2 In some embodiments, the two sliding parts 1011 and the two limiting parts 1012 together form a clamping space, the cross-sectional shape of the extension part 301 is the same as the cross-sectional shape of the clamping space, and when the connecting member 300 extends into the clamping space, the minimum outer diameter of the extension part 301 is located between the two limiting parts 1012, and the maximum outer diameter of the extension part 301 is located between the two sliding parts 1011, so that the extension part 301 can extend into the clamping space without hindrance. One end of the extension part 301 is slidably disposed in the second connecting hole, and the other end is used to extend into or extend out of the first connecting hole 101.

[0065] The minimum outer diameter of the extension portion 301 is no greater than the second spacing, and the maximum outer diameter of the extension portion 301 is greater than the second spacing and no greater than the first spacing, so that the extension portion 301 can smoothly extend into the first connecting hole 101, and after the connecting member 300 rotates a preset angle, the clamping space can correctly squeeze the extension portion 301 of the connecting member 300, thereby achieving a technical effect of stable connection.

[0066] It should be noted that the preset rotation angle of the connecting member 300 should be set according to actual conditions. The squeezing of the extension portion 301 by the clamping space is essentially the rotation of the maximum outer diameter portion of the extension portion 301 to between the two limit portions 1012. The smaller the gap between the outer diameter of the extension portion 301 and the clamping space, the smaller the preset rotation angle required, and the larger the gap between the outer diameter of the extension portion 301 and the clamping space, the larger the preset rotation angle required.

[0067] Reference Figure 3 In some embodiments, the guide portion 302 is disposed at one end of the extension portion 301 close to the first connection hole 101 and connected thereto, and the outer diameter of the guide portion 302 gradually decreases from one end close to the extension portion 301 to the other end; when the connecting member 300 is to be extended into the first connection hole 101, the end of the guide portion 302 with the smallest outer diameter enters the first connection hole 101 first, thereby avoiding spending too much time when the connecting member 300 is docked with the first connection hole 101, thereby shortening the connection time and making it convenient and quick.

[0068] Reference Figure 3 In some embodiments, the guide portion 302 guides the extension portion 301 to extend into the clamping space, and after the connecting member 300 rotates along the extending direction, the maximum outer diameter portion of the extension portion 301 is transferred from between the two sliding portions 1011 to between the two limiting portions 1012, and the two limiting portions 1012 are in a state of squeezing the extension portion 301, which is used to limit the connecting member 300 from continuing to rotate, and / or to prevent the connecting member 300 from rotating in the reverse direction.

[0069] It should be noted that when the maximum outer diameter of the extension portion 301 is turned from between the two sliding portions 1011 to between the two limit portions 1012, the first rotation direction of the connecting member 300 revolves around the sliding direction when it extends into the first connecting hole 101. Since the maximum outer diameter of the extension portion 301 is greater than the second spacing, the connecting member 300 will not be able to continue to rotate after rotating by a preset angle; when the maximum outer diameter of the extension portion 301 is turned from between the two limit portions 1012 to between the two sliding portions 1011, the extrusion force of the two limit portions 1012 hinders the rotation of the connecting member 300. Therefore, at this time, the second rotation direction of the connecting member 300 should be opposite to the first rotation direction, and the connecting member 300 needs to overcome the component of the extrusion force in the second rotation direction, so that the connecting member 300 can rotate along the second rotation direction to a position where it can slide normally.

[0070] Reference Figure 1 and Figure 7 In some embodiments, the clearance opening 201 is provided on the second mounting member 200, one end of the adjusting member 400 passes through the clearance opening 201 and extends into the second mounting member 200, and the adjusting member 400 is detachably connected to the connecting member 300.

[0071] The athlete can quickly control the connection member 300 to slide or rotate through the adjusting member 400. When maintenance is needed, the connection between the adjusting member 400 and the connection member 300 can be disconnected, and the connection member 300 can be taken out from the second connecting hole, which is convenient for maintenance. In some embodiments, a threaded hole is penetrated through the connection member 300, and one end of the adjusting member 400 is provided with an external thread, and the adjusting member 400 is threadedly connected to the connection member 300.

[0072] Reference Figure 1 and Figure 7 In some embodiments, the yielding opening 201 includes a telescopic opening 2011 and a rotating opening 2012, wherein the telescopic opening 2011 extends along the direction in which the connecting member 300 extends into or out of the first connecting hole 101, and the extending direction of the rotating opening 2012 is perpendicular to the extending direction of the telescopic opening 2011, and the rotating opening 2012 is connected to the telescopic opening 2011. The athlete can quickly control the connecting member 300 to extend into or out of the first connecting hole 101 through the telescopic opening 2011, so that the first mounting member 100 is connected to the second mounting member 200; the athlete can quickly control the rotation of the connecting member 300 through the rotating opening 2012, so that the clamping space squeezes or releases the connecting member 300, thereby making the connection between the first mounting member 100 and the second mounting member 200 relatively stable or relatively free.

[0073] Reference Figure 7 In some embodiments, the two rotating openings 2012 are respectively arranged at both ends of the telescopic opening 2011, and the extension directions of the two rotating openings 2012 are opposite. They are used to limit the connecting member 300 in the second connecting hole after the connecting member 300 extends out of the first connecting hole 101, so as to avoid interference when the athlete performs split-motion training, and after the connecting member 300 extends into the first connecting hole 101, the rotation angle of the connecting member 300 is limited to not greater than a preset angle, so as to avoid excessive rotation resistance of the clamping space to the connecting member 300 when reverse rotation is required to disconnect the connection. Specific embodiment 2

[0075] The present application also provides a training device, which is provided with the connection structure described in the above-mentioned specific embodiment 1. The training device includes a base 500, two upright frames 600 and two swing frames 700, wherein the two upright frames 600 are relatively arranged at two ends of the base 500, a rotating shaft 1400 is provided between the two upright frames 600, the two swing frames 700 are relatively arranged and are respectively rotatably arranged on the rotating shaft 1400, and the two swing frames 700 are respectively provided with a first mounting member 100 and a second mounting member 200, and the first mounting member 100 and the second mounting member 200 are detachably connected through the connection structure.

[0076] Reference Figures 4 to 7In some embodiments, the base 500 is a long strip frame structure, and the two upright frames 600 are arranged at one end of the base 500 relatively along the width direction of the base 500. The end of the two upright frames 600 away from the base 500 is provided with a rotating shaft 1400, and the rotating shaft 1400 is rotatably connected to one end of the two swing frames 700 respectively. The other end of the two swing frames 700 is used for athletes to grasp for training, and the first mounting member 100 and the second mounting member 200 are respectively provided on the side close to each other on the two swing frames 700.

[0077] Reference Figure 4 In some embodiments, one end of the first mounting member 100 is fixedly connected to the swing frame 700, and the other end of the first mounting member 100 is provided with a first connecting hole 101 for connection. The first mounting member 100 is also provided with a first auxiliary member, one end of the first auxiliary member is fixedly connected to the first mounting member 100, and the other end of the first auxiliary member is rotatably connected to the rotating shaft 1400. The first auxiliary member is used to share stress to avoid excessive stress and breakage at the fixed connection between the first mounting member 100 and the swing frame 700; the first mounting member 100 is provided with a second connecting hole at one end close to the second mounting member 200 for connection, and the second mounting member 200 is provided with a second auxiliary member. The connection structure of the second mounting member 200 is the same as that of the first mounting member 100, which will not be repeated here.

[0078] Reference Figures 4 to 7 In some embodiments, an adjustment seat 800 is fixedly provided on the base 500, and at least two adjustment holes are formed on the adjustment seat 800, and the arrangement direction of the two adjustment holes extends in a direction away from the base 500. The support member 900 is rotatably disposed at one end of the adjustment seat 800 away from the base 500, and one end of the positioning member 1000 passes through the support member 900 and is slidably disposed in the adjustment hole, and the other end of the positioning member 1000 is used for the athlete to grasp so as to place the positioning member 1000 into the adjustment hole that meets the requirements.

[0079] The support member 900 is used to place the athlete's legs to meet the athlete's single-leg support training needs. Due to the different heights of athletes, the height of the support member 900 is required to be inconsistent. The athlete adjusts the height of the support member 900 by placing the positioning member 1000 into different adjustment holes.

[0080] Reference Figure 4 , Figure 6 as well as Figure 7In some embodiments, two first handles 1100 are respectively provided at one end of the two swing frames 700 away from the rotation axis 1400, and two second handles 1200 are respectively provided at one side of the two first handles 1100 close to the base 500. Athletes grasp the first handles 1100 or the second handles 1200 to facilitate pulling the swing frames 700 to rotate around the rotation axis 1400 for training. Athletes can choose the first handle 1100 or the second handle 1200 according to different training needs.

[0081] Reference Figure 4 , Figure 5 as well as Figure 7 In some embodiments, the two load-bearing members 1300 are respectively fixed on one end of the two swing frames 700 away from the rotating shaft 1400, the two spare weight members 1500 are respectively fixed on one end of the two vertical frames 600 away from the base 500, at least two weight-increasing members are respectively slidably arranged on the two load-bearing members 1300, or at least two weight-increasing members are respectively slidably arranged on the two spare weight members 1500.

[0082] The weight-increasing piece is a weight plate, and the weight of the weight-increasing piece is set according to actual conditions. When the weight-increasing piece is not needed, it is placed on the spare weight piece 1500 to save space. When the weight-increasing piece is placed on the load-bearing piece 1300, it is used to increase the resistance of the swing frame 700 to rotate around the rotating shaft 1400, thereby meeting the athlete's needs for high-resistance training.

[0083] When an athlete wants to use the training device of the present application for linkage training, the connecting member 300 is controlled by the adjusting member 400 to slide out from the second connecting hole, and under the guidance of the guide part 302, the end of the connecting member 300 away from the second connecting hole is extended into the first connecting hole 101, and the connecting member 300 is controlled by the adjusting member 400 to rotate along the first rotation direction again, so that the maximum outer diameter part of the extension part 301 is turned from between the two sliding parts 1011 to between the two limiting parts 1012, and the two limiting parts 1012 are in a state of squeezing the extension part 301, thereby stabilizing the connection between the first mounting member 100 and the second mounting member 200. When the athlete squats down and grasps the first handle 1100 or the second handle 1200, and performs training by squatting and standing up through leg force cycle, the two swing frames 700 rotate synchronously around the rotation axis 1400 to complete the linkage training.

[0084] When an athlete wants to use the training device of the present application for split-motion training, the connecting member 300 is controlled to rotate along a second rotation direction opposite to the first rotation direction through the adjusting member 400, so that the maximum outer diameter portion of the extension portion 301 is turned from between the two limiting portions 1012 to between the two sliding portions 1011, and the extension portion 301 can slide freely between the two sliding portions 1011, and then the connecting member 300 is controlled to slide out from the first connecting hole 101 through the adjusting member 400, and the adjusting member 400 cooperates with the rotating mouth 2012 to keep the adjusting member 400 in a state of extending into the second connecting hole, thereby disconnecting the first mounting member 100 from the second mounting member 200, and the athlete squats down and grasps the first handle member 1100 or the second handle member 1200, with one leg resting on the supporting member 900, and performs training by squatting and standing up in a cycle with a single leg, and the unilateral swing frame 700 rotates around the rotating shaft 1400 to complete the split-motion training.
