[0040] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] One embodiment of the present invention is, please refer to Figures 1 to 23 , a leg support fixing mechanism, the leg support fixing mechanism comprises: a plurality of first guide rods 200; a sliding member 1100, which is slidably connected to the plurality of first guide rods 200 respectively, the sliding member 1100 is rotatably connected with a first rotating member 1200 and a second rotating member 1300 respectively, the end of the first rotating member 1200 extending out of the sliding member 1100 is a first rotating end 1210, and the end of the second rotating member 1300 extending out of the sliding member 1100 is a second rotating end 1310, the first rotating end 1210 and the second rotating end 1310 are symmetrically distributed on both sides of the sliding member 1100; a transmission belt 300, which is connected to the sliding member 1100 and drives the sliding member 1100 to slide; a leg wrap member 1400, which is detachably fixedly connected to any one of the first rotating end 1210 and the second rotating end 1310; and a leg support mechanism 500, the leg wrap member 1400 is used to wrap the training leg, and the leg support mechanism 500 is used to support the non-training leg.

[0043] In the embodiments of the present invention, reference Figure 1 and 2 The plurality of first guide rods are parallel to each other, and may be, but not limited to, two first guide rods are provided and arranged in the vertical direction. The plurality of first guide rods are respectively slidably connected to the sliding member, and the sliding member can slide along the guide of the first guide rod. The first guide rod may be, but not limited to, movably fixedly connected with a stopper 2110, and the stopper 2110 is located below the sliding member, and the stopper 2110 can stop the sliding member to prevent the sliding member from sliding to the bottom of the first guide rod.

[0044] The sliding member is rotatably connected with a first rotating member and a second rotating member respectively, one end of the first rotating member extending out of the sliding member is the first rotating end, and one end of the second rotating member extending out of the sliding member is the second rotating end, the first rotating end and the second rotating end are located on both sides of the sliding member, and the leggings member is detachably fixedly connected with the first rotating end or the second rotating end. When the user performs a hip training test, the leggings member is fixedly connected with the first rotating end, and one leg is bound to the leggings member. The driving mechanism drives the sliding member to reciprocate through the transmission belt, and then drives the leg bound to the leggings member to swing back and forth. During the reciprocating swing of the leggings member, the first rotating member rotates relative to the sliding member, so that the leg can be close to the leggings member. When it is necessary to change the training leg, the leggings member is loosened from one leg, the leggings member is removed from the first rotating end and then fixed to the second rotating end, the other leg of the user is bound to the leggings member, and the hip training test is performed on the other leg, and the user can easily change the training leg.

[0045] When the user performs a hip training test, the training leg can be tied to the leggings and the non-training leg can be placed on the leg support mechanism. The leg support mechanism can support the non-training leg, and the user can relax the non-training leg and concentrate the strength on the training leg to perform the hip training test, so that the user can exert force reasonably and ensure the effect of the hip training test. At the same time, the leg support mechanism can prevent the non-training leg from being suspended in the air, ensuring the safety of the user's hip training test.

[0046] Furthermore, the leg support mechanism 500 includes at least one leg support member 5100, and the leg support member 5100 includes a connecting tube 5110 and a support assembly 5120. The connecting tube 5110 is fixedly connected to the first guide rod 200 in a changeable fixed position. The support assembly 5120 includes a support seat 5121. The connecting tube 5110 supports the support assembly 5120. The support seat 5121 is used to support the non-training leg. The support seat 5121 and the legging member 1400 are located on both sides of the sliding member 1100.

[0047] In an embodiment of the present invention, the connecting tube is fixedly connected to the first guide rod in a changeable fixed position. When the user adjusts the connection position of the leggings component and the sliding component, the fixed position of the connecting tube and the first guide rod can be adjusted accordingly to ensure that the support seat and the leggings component are located on both sides of the sliding component, so that the leg support mechanism can support the non-training leg. Through the adjustable position connection of the leggings component and the sliding component and the changeable fixed position connection of the connecting tube and the first guide rod, the hip training test device only needs to be provided with one leggings component and one leg support mechanism to realize separate hip training tests for both legs, without the need to provide two leggings components and two leg support mechanisms, thereby simplifying the structure of the hip training test device.

[0048] The support seat may be, but is not limited to, set to a U shape, so that when the non-training leg is placed on the support seat, the support seat can better support the non-training leg, thereby preventing the non-training leg from detaching from the support seat during the hip training test of the training leg. A leg pad 5121a may be set on the side of the support seat supporting the non-training leg, and the leg pad 5121a can buffer the force and protect the non-training leg.

[0049] Furthermore, one end of the connecting tube 5110 is rotatably connected to the first guide rod 200, and the connecting tube 5110 is provided with a pull pin 5111, which includes a pull pin rod 5112 and a pull pin sleeve 5113 that are slidably connected, and the pull pin sleeve 5113 is fixedly connected to the connecting tube 5110, and the first guide rod 200 is fixedly connected with an adjustment plate 2120, and a plurality of adjustment holes 2121 are provided on the adjustment plate 2120, and the pull pin rod 5112 is inserted into different adjustment holes 2121 to change the fixed position of the connecting tube 5110 and the first guide rod 200.

[0050] In an embodiment of the present invention, one end of the connecting tube is rotatably connected to the first guide rod. For example, the connecting tube and the first guide rod are rotatably connected via a rotating sleeve 5133 and a rotating shaft 5134, but the present invention is not limited thereto.

[0051] The connecting tube is provided with a pull pin. When the pull pin rod is inserted into the adjustment hole, the connecting tube cannot rotate relative to the first guide rod; when the pull pin rod is disengaged from the adjustment hole, the connecting tube can rotate relative to the first guide rod. When it is necessary to change the fixed position of the connecting tube and the first guide rod, it is only necessary to pull the pull pin so that the pull pin rod is disengaged from the adjustment hole, and then rotate the connecting tube. After the position of the connecting tube is adjusted, the pull pin rod is inserted into the adjustment hole to prevent the connecting tube from rotating, making adjustment convenient. Of course, the pull pin is also provided with a spring. When the pull pin is not subjected to external force, the elastic force of the spring keeps the pull pin rod inserted into the adjustment hole, which can prevent the pull pin rod from being disengaged from the adjustment hole during the hip training test, thereby ensuring the reliability and stability of the connection between the connecting tube and the first guide rod.

[0052] The number of adjustment holes provided on the adjustment rod may correspond to the fixed position of the connecting tube. The plurality of adjustment holes are all located on the movement path of the pull pin rod, so that the pull pin rod can be smoothly inserted into the adjustment holes. The adjustment holes may be distributed on both sides of the first guide rod. When the pull pin rod is inserted into different adjustment holes, the support seat and the leggings component are located on both sides of the sliding component. The adjustment holes may be distributed on one side of the first guide rod. When the pull pin rod is inserted into different adjustment holes, the distance between the support seat and the leggings component can be adjusted to meet different training needs of users.

[0053] Furthermore, it also includes a first fixing member 5130 and a second fixing member 5140 , the first fixing member 5130 and the second fixing member 5140 clamp and fix the plurality of first guide rods 200 , and the connecting pipe 5110 is rotatably connected to the first fixing member 5130 .

[0054] In an embodiment of the present invention, the first fixing member and the second fixing member can be fixed by a plurality of bolts. Tightening the plurality of bolts can make the first fixing member and the second fixing member close to each other and clamp and fix the plurality of first guide rods. Loosening the plurality of bolts can separate the first fixing member and the second fixing frame from each other, and the first fixing member and the second fixing frame can loosen the first guide rod, thereby changing the position of the first fixing member and the second fixing member on the first guide rod, and adjusting the fixed position of the first fixing member and the second fixing frame on the first guide rod, thereby adjusting the height of the support seat, and the user can adjust according to the training requirements, thereby meeting the different training requirements of the user.

[0055] It is possible but not limited to that the first fixing member is provided with a receiving groove 5131 for accommodating the second fixing member, and the first fixing member and the second fixing member are respectively provided with arc grooves 5132 at positions opposite to the first guide rod, so that the first fixing member and the second fixing member can fit the outer wall of the first guide rod more closely, thereby ensuring the reliability of the first fixing member and the second fixing member clamping the first guide rod.

[0056] The connection tube and the first fixing member may be connected to each other by a rotating sleeve 5133 and a rotating shaft 5134, and the rotating shafts are provided in two and located at both ends of the first fixing member. The leg support mechanism includes two leg support members, and a connection tube of a leg support member is connected to a rotating shaft, and the two leg support members can jointly support the non-training leg, thereby ensuring the stability of the support. When the two support members support the non-training leg, the two ends of the first fixing member are stressed, and the first fixing member and the second fixing member clamp a plurality of first guide rods, so that the overall stress is more balanced, further improving the stability of the leg support mechanism.

[0057] Furthermore, a first limit piece 2122 and a second limit piece 2123 are provided on the side of the adjustment plate 2120 facing the pin sleeve 5113, and one end of the pin sleeve 5113 extending from the connecting tube facing the adjustment plate 2120 is a stop end 5113a, and the stop end 5113a moves between the first limit piece 2122 and the second limit piece 2123.

[0058] In an embodiment of the present invention, the adjustment plate is provided with a first limiter and a second limiter, and the pin pull sleeve is provided with a stop end. The first limiter and the second limiter can respectively stop the stop end to limit the range of motion of the pin pull sleeve, that is, to limit the rotation range of the connecting pipe relative to the first guide rod. When adjusting the fixed position of the connecting pipe and the first guide rod, excessive rotation of the connecting pipe is avoided, and collision of the connecting pipe with other structures can be avoided. It can also be avoided that the connecting pipe collides with the user, thereby ensuring the personal safety of the user. It can be, but is not limited to, that the first limiter and the second limiter are respectively provided with a buffer sleeve, which can buffer the collision of the pin pull sleeve.

[0059] Furthermore, the leg supporting mechanism 500 includes a plurality of leg supporting members 5100 , and the plurality of leg supporting members 5100 are connected via a connecting rod 5200 .

[0060] In an embodiment of the present invention, the leg support mechanism includes a plurality of leg support members, and the plurality of leg support members can support the non-training leg together, thereby ensuring the reliability of the leg support mechanism in supporting the non-training leg. The plurality of leg support members are connected by a connecting rod, and the connecting rod can enable the plurality of leg support members to be linked to achieve synchronous movement. When the position of the leg support mechanism needs to be adjusted, only one of the leg support members needs to be driven to move, and the other leg support members will also move together, thereby facilitating the adjustment of the leg support mechanism.

[0061] Furthermore, the support assembly 5120 includes a support rod 5122, which is fixedly connected to the support seat 5121. The support rod 5122 is inserted into the connecting tube 5110. When the connecting tube 5110 and the first guide rod 200 are in different fixed positions, the angle between the connecting tube 5110 and the horizontal plane is equal to the angle between the support rod 5122 and the support seat 5121.

[0062] In the embodiment of the present invention, the support rod is inserted into the connecting tube, and the connecting tube can support the support seat and the non-training leg. After adjusting the position of the connecting tube, the support rod can be pulled out of the connecting tube, and the supporting seat can be rotated and then inserted into the connecting tube. Before and after adjusting the position of the connecting tube, the supporting seat can maintain a horizontal position, so that the supporting seat can support the non-training leg.

[0063] When the connecting pipe and the first guide rod are in different fixed positions, the angle between the connecting pipe and the horizontal plane is equal to the angle between the support rod and the support seat. After the support rod is inserted into the connecting pipe, the support rod is parallel to the connecting pipe. Figure 2 The direction shown in the figure is used as an example for detailed description. As shown in the figure, the leggings are located on the right side of the sliding member, and the support seat is located on the left side of the sliding member. When the leggings and the support seat need to be adjusted, that is, the leggings are adjusted to the left side of the sliding member and the support seat is adjusted to the right side of the sliding member, the support rod is pulled out of the connecting tube, the support seat is horizontally rotated 180 degrees, and then the support rod is inserted into the connecting tube, so that the support seat is in the same horizontal plane when it is on the left and right side of the sliding member, and the support seat will not tilt, thereby ensuring the stability of the support seat supporting the non-training leg.

[0064] Furthermore, the connecting tube 5110 is provided with a stop rod 5114 , and one end of the support rod 5122 inserted into the connecting tube 5110 is provided with a stop groove 5122a , and the stop rod 5114 is inserted into the stop groove 5122a to prevent the support rod 5122 from rotating relative to the connecting tube 5110 .

[0065] In an embodiment of the present invention, after the support rod is inserted into the connecting tube, the anti-rotation rod will be placed in the anti-rotation groove, and the anti-rotation rod will stop the connecting tube from rotating. When performing a hip training test, the support rod cannot rotate relative to the connecting tube, thereby ensuring the stability of the support seat supporting the non-training leg. When it is necessary to adjust the position of the support seat, the support rod can be pulled so that the anti-rotation rod is disengaged from the anti-rotation groove, and the support seat can be rotated without completely pulling the support seat out. After adjusting the position of the support seat, the support rod can be inserted again so that the anti-rotation rod is placed in the anti-rotation groove, which is convenient for adjustment.
