Embodiment 1

As shown in Figure 1 and Figure 2, a kind of hook leg support adjustment structure, including U-shaped frame 1 are provided with supporting rack 11, seat on U-shaped frame 1 Chair 2, handrail 6 hook leg pad 14, hook leg support 13, swing span 9 and regulating mechanism, hook leg support 13 and are flexibly connected with swing span 9, are swung Frame 9 is flexibly connected with supporting rack 11, and the regulating mechanism includes regulation handle 4, adjustable plate 5 and support plate 10, regulation handle 4 End is connected by bolt and swing span 9, and swing span 9 has adjustable plate 5, adjustable plate 5 first-class close to the end set of regulation handle 4 Spacing arrangement is provided with limit hole, and resilient pin 3 is arranged in the end of regulation handle 4, and the fork of resilient pin 3 is plugged in adjusting In the limit hole of plate 5；The support plate 10 and hook leg support 13 connect, end and support plate 10 of the swing span 9 far from regulation handle 4 Flexible connection is equipped with connecting rod 7 between the adjusting bracket and support plate 10 of regulation handle 4.

Adjustable plate 5 raises up along the end of swing span 9 and is set as arch bridge arc panel.The arc-shaped curved surface of arch bridge arc panel Structure is that regulation handle 4 provides limit space, and different limit holes plays limit to regulation handle 4 and makees on arch bridge arc panel With by pulling the drive 4 each adjustment of displacement fast and stable of regulation handle of resilient pin 3, simple operation, by relatively small Displacement distance realizes that control hooks leg support 13, hooks the relative displacement between leg pad 14 and seat 2.

U-shaped seat 15 is welded in the end of regulation handle 4 by screw thread pin bushing, and 15 one end of U-shaped seat passes through bolt and swing span 9 Connection, the other end and connecting rod 7 flexible connection of U-shaped seat 15.U-shaped seat 15 plays the role of transition connection, ensures that regulating mechanism exists When adjusting position, connecting rod 7 links freely between each other along 15 moving rotary of U-shaped seat, all parts.

10 Parallel Symmetric of support plate is provided with a pair, and the lower end of two blocks of parallel support plates 10, which is welded to, to be hooked in leg support 13, and two Arrangement is provided with support shaft 8 and middle support shaft 12 successively from top to bottom between a support plate 10, and the support plate 10 is set as One end is narrow and elliptical flat-plate that the other end is wide, upper support shaft 8, middle support shaft 12 and hook leg support 13 diameter it is incremented by successively.Upper branch The bushing for supportting axis 8 and 7 end of connecting rod is flexibly connected, the bushing flexible connection of the end of middle support shaft 12 and swing span 9.

Double layer support plate 10 plays stable supporting role, and special planform compressive resistance is strong, and each component is avoided to send out Raw deformation, while ensureing stable between each component；Hook leg support 13 is relatively large in diameter, the coordinated with swing span 9, both It needs to meet itself stronger support force, while strong support guarantee, upper support is provided to hook leg support 13, hooking leg pad 14 Axis 8 is flexibly connected with connecting rod 7, and the required support force of 7 displacement of connecting rod is relatively small, the diameter dimension of connecting rod 7 and upper support shaft 8 It is smaller, make regulation handle 4 that there is adjustment stability.

It hooks leg pad 14 and is set as cylinder roller, outer wall is prepared using elastic material.It is provided centainly for leg Support force there is certain elastic buffer power, improve comfort level when making leg be placed on to hook on leg pad 14.

The lower section of handrail 6 is connected with leg pressing pad, and leg pressing pad and the relative position hooked between leg pad 14 are adjustable.Leg pressing pad The upper leg portion for being placed on and hooking on leg pad 14 is pushed down, stable position-limiting action is played to thigh.

Hook leg support 13 specific adjustment process be：

When not adjusting, the fork of the resilient pin 3 in regulation handle 4 is plugged in the limit hole of adjustable plate 5, is used When, drive regulation handle 4 to be pulled out from the limit hole of arc adjustable plate 5 by pulling resilient pin 3, at this point, under regulation handle 4 The U-shaped seat 15 at end is rotated relative to swing span 9, and 15 drive link 7 of U-shaped seat movement, connecting rod 7 drives support plate 10 with middle support shaft 12 swing up and down for moving fulcrum, when the fork of the resilient pin 3 in regulation handle 4 is plugged in close to the limit hooked at leg support 13 When the hole of position, hooks leg support 13 and move down；When the fork of the resilient pin 3 in regulation handle 4 is plugged in far from hook leg support 13 Limit hole when, hook leg support 13 move up；Rapid and convenient is adjusted, operation easy to produce, adjusting is laborsaving, convenient.

The specifically used process of the device is：

People sits on the seat 2 of machine, according to the height and weight for waiting for person taking exercise, adjusts the back cushion of seat 2 to suitable position It sets, after adjustment hooks leg support 13 and the relative position relation of hook leg pad 14 and seat 2, adjusting hook leg pad 14, will to suitable position Leg is put into the top for hooking leg pad 14, adjustable handrail 6, leg-pressing frame position, so that the leg pressing pad being connected with handrail 6 is pushed down on thigh Portion starts to hook leg training.

The above is not limitations of the present invention, it should be pointed out that：For the ordinary skill people of the art For member, under the premise of not departing from the utility model in essence range, several variations, modifications, additions or substitutions can also be made, These improvements and modifications also should be regarded as the scope of protection of the utility model.
