Embodiment 1

[0024] Please refer to the drawings of the utility model Figures 1-4 , the embodiment of the utility model is unfolded, a foldable foot pedal trainer: including fixed seat 1, the fixed seat 1 is fixedly connected with support rod 2, the support rod 2 is fixedly connected with rotating sleeve 3, the rotating sleeve 3 is rotatably connected with resistance rotating shaft 4, and the both ends of the resistance rotating shaft 4 are fixedly connected with folding rocker 5;The folding rocker 5 includes connecting sleeve 501, the connecting sleeve 501 is slidably connected with fixed pin 502, the connecting sleeve 501 is rotatably connected with the resistance rotating shaft 4, the resistance rotating shaft 4 is provided with fixed hole 503 matched with fixed pin 502, the first support rod 504 is fixedly connected at the lower end of the connecting sleeve 501, the connecting block is fixedly connected at the lower end of the first support rod 504, and the second support rod 505 is arranged in the connecting block.

[0025] The fixed seat 1 and the support rod 2 are used for the fixation and support of the whole device, the fixed seat 1 is a stable base or holder, in use, the device is stably placed in front of the user through the fixed seat 1, the support rod 2 is used for adjusting the height of the rotating sleeve 3, the rotating sleeve 3 supports and limits the rotation of the resistance rotating shaft 4, the resistance rotating shaft 4 has two folding rocker arms 5 on both sides, the two folding rocker arms 5 are respectively located on the left and right sides of the rotating sleeve 3, in the initial state, the two folding rocker arms 5 are located below the resistance rotating shaft 4, at this time, the two folding rocker arms 5 are located on the left and right sides of the support rod 2, at this time, the rotating sleeve 3 is the highest point of the device, which improves the folding property of the device and reduces the volume of the device, in use of the device, one of the two folding rocker arms 5 rotates one hundred and eighty degrees relative to the resistance rotating shaft 4, so that the two folding rocker arms 5 are located above and below the resistance rotating shaft 4, which is more in line with the force during foot training and provides a more comfortable experience for training.

[0026] The rotation and fixation between the folding rocker arm 5 and the resistance rotating shaft 4 are controlled through the fixed pin 502 and the fixed hole 503, wherein the fixed pin 502 is slidingly connected to the connecting sleeve 501, the resistance rotating shaft 4 in the connecting sleeve 501 has a fixed hole 503, the fixed hole 503 and the fixed pin 502 are in interference fit, when the folding rocker arm 5 needs to be rotated, the fixed pin 502 needs to be pulled out of the fixed hole 503, at this time, the folding rocker arm 5 and the resistance rotating shaft 4 can be relatively rotated, after the folding rocker arm 5 is rotated one hundred and eighty degrees, the fixed pin 502 is inserted into the fixed buckle for fixation, that is, the reversing work of the folding rocker arm 5 is completed; the first branch 504 and the second branch 505 in the folding rocker arm 5 can also be folded, the connecting block is installed at the lower end of the first branch 504 and the inner end of the second branch 505, in the folded state, the second branch 505 can be upwardly rotated, the first branch 504 and the second branch 505 are rotated to the vertical parallel state, in use, the second branch 505 is reversely rotated, the second branch 505, the connecting block and the first branch 504 form an L-shaped structure, which facilitates the user to exert force during exercise and provides a more stable force point for the user's feet.

[0027] Further, to avoid that the angle of the second branch 505 downwardly rotating is too large, the outer end of the second branch 505 has an upwardly inclined angle, so that the force between the feet and the second branch 505 has an inward component, which can avoid the feet from slipping outwardly relative to the second branch 505, the second branch 505 and the connecting block are in interference fit, the second branch 505 is fixed through the friction force between them, in addition, the first branch 504 below is provided with a limiting groove 506, the limiting groove 506 limits the downward rotation of the second branch 505, so that the limit position of the second branch 505 downwardly rotating is the horizontal placement state of the second branch 505.

[0028] The friction pad 6 is made of the same material as the drum brake pads of the vehicle. The first adjusting screw 7 is used to adjust the preload of the friction pad 6 relative to the resistance shaft 4. The resistance value of the resistance shaft 4 is adjusted by adjusting the first adjusting screw 7. The change in resistance value adjusts the force applied by the user to drive the folding rocker arm 5 to rotate, which increases the load on the limbs and improves the stimulation effect on the muscles.

[0029] The upper pressure plate 103 and lower pressure plate 102 on the fixed base 1 are used to clamp objects. When the device is fixed on the plate or the rod, the lower pressure plate 102 is located below the plate. At this time, the second adjusting screw 104 is rotated so that the upper pressure plate 103 clamps above the plate. At this time, the long pressure plate and the lower pressure plate 102 fix the plate and the support block 101 together, thereby completing the fixed installation of the device.

[0030] Furthermore, to facilitate the adjustment of the height of the folding rocker arm 5, the support rod 2 consists of a first slide rod 201 and a second slide rod 202 that can slide relative to each other. The relative sliding of the first slide rod 201 and the second slide rod 202 can adjust the overall length of the support rod 2. The second slide rod 202 has multiple cylindrical holes 203. The first slide rod 201 and the second slide rod 202 can be fixed by screws passing through the cylindrical holes 203. In addition, a telescopic ball can be slidably connected to the first slide rod 201. The first slide rod 201 and the second slide rod 202 are fixed by the cooperation of the telescopic ball and the cylindrical holes 203. The adjustment method of the telescopic ball is similar to the principle of the pull rod of a suitcase, which is existing technology and will not be described in detail here. In addition, the slot 8 on the fixing seat 1 is an inverted T-shaped structure, so that the first support rod is more stably fixed on the fixing seat 1. Example 2

[0031] The structure is the same as that of the above embodiments, such as Figure 5 and Figure 6 As shown, the specific difference in this embodiment is that: the bottom of the support rod 2 is rotatably connected to an angle adjustment block 9, the angle adjustment block 9 is fixedly connected to the fixed base 1, the angle adjustment block 9 is provided with a plurality of equidistantly distributed limiting holes 10, the support rod 2 is provided with an adjustment hole that cooperates with the limiting holes 10, and a limiting pin 11 is inserted into the limiting hole and the adjustment hole.

[0032] The upper end of the angle adjusting block is a fan-shaped structure, the hinge point of the support rod 2 and the angle adjusting block 9 is located at the center of the fan-shaped circle, the limiting hole 10 has multiple, the distances from the multiple limiting holes 10 to the hinge point of the support rod 2 are same, when the support rod 2 is fixed, the limiting pin 11 is inserted into the limiting hole 10 and the adjusting hole, at this time, the lower end of the support rod 2 has the hinge point and the point of the limiting pin 11 fixed on the angle adjusting block 9, the position of the support rod 2 is fixed through the above two points, when the support rod 2 needs to be adjusted, the limiting pin 11 is pulled out, the limiting pin 11 is inserted into other limiting hole 10, then the support rod 2 is rotated to adjust the hole to the position of the limiting pin 11, then the limiting pin 11 is inserted to be fixed.
