DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 - Figure 6 A leg trainer with an adjustment mechanism shown in the figure comprises a trainer body 1, the trainer body 1 comprises an upper plate 101 and a lower plate 102, an adjustment component 2 for adjusting the height of the upper plate 101 is provided at the upper end of the lower plate 102, and a quick adjustment component 3 for quickly unlocking the lower plate 102 is provided at the lower end of the upper plate 101;

[0025] The adjusting component 2 includes two connecting sleeves 201 fixedly arranged on the upper end of the lower plate 102, and two connecting columns 202 are fixedly arranged on the lower end of the upper plate 101. The outer side of the connecting column 202 slides on the inner side of the connecting sleeve 201. A plurality of snap-in holes 203 are opened at one end of the connecting sleeve 201, and the snap-in holes 203 pass through the connecting sleeve 201. A U-shaped rod 204 is arranged at the lower end of the upper plate 101, and the end of the U-shaped rod 204 slides on the inner side of the connecting column 202. Two limit blocks 206 are slidably arranged at the end of the U-shaped rod 204, and a limit spring 207 is fixedly arranged between the two limit blocks 206. The limit block 206 is snapped on the inner side of the corresponding snap-in hole 203, so as to limit the connecting column 202 through the snap-in hole 203.

[0026] In the embodiment of the utility model, the quick adjustment component 3 includes a guide rod 301 fixedly arranged on the upper end of the lower plate 102, and a guide groove 302 is opened on the upper end of the U-shaped rod 204. The outer side of the guide rod 301 slides on the inner side of the guide groove 302, thereby forming a U-shaped rod 204 that can only move back and forth.

[0027] In the embodiment of the utility model, a rectangular groove 306 for sliding of the limit block 206 is opened at the end of the U-shaped rod 204, and a clamping plate 307 is fixed at both ends of the limit block 206. A first inclined surface 304 is provided at one end of the limit block 206 corresponding to the connecting column 202, and a second inclined surface 305 is provided at the end of the limit block 206 away from the guide rod 301. The first inclined surface 304 and the second inclined surface 305 are inclined.

[0028] In the embodiment of the utility model, a plurality of limit plates 303 are fixedly provided at the end of the U-shaped rod 204 , and every two limit plates 303 are located on both sides of the connecting column 202 to prevent the U-shaped rod 204 from moving too much.

[0029] In the embodiment of the utility model, the height of the guide rod 301 is equal to the height 11 of the connecting sleeve 201, so as to ensure that the guide rod 301 will not interfere with the upper plate 101 after the upper plate 101 moves downward to a limit distance.

[0030] In the embodiment of the utility model, a through slot 205 for the U-shaped rod 204 to pass through is opened in the middle of the connecting sleeve 201 . The through slot 205 runs through the connecting sleeve 201 , and the connecting sleeve 201 facilitates the U-shaped rod 204 to slide up and down on the connecting sleeve 201 .

[0031] Working principle: the operator places the connecting column 202 in the adjusting component 2 into the connecting sleeve 201 to assemble the upper plate 101 and the lower plate 102, and then directly pushes the U-shaped rod 204 forward, and the U-shaped rod 204 slides inside the guide rod 301 through the guide groove 302 in the quick adjustment component 3, and then through the limit of the guide rod 301, the moving direction of the U-shaped rod 204 is limited, and the U-shaped rod 204 can also be axially supported. The U-shaped rod 204 then drives the limit block 206 to move, so that the second inclined surface 305 contacts the connecting sleeve 201, and then through the inclined surface setting, the two corresponding limit blocks 206 are close to each other, and then continue to push the U-shaped rod 204, so that the limit block 206 is disengaged from the clamping hole 203, so that the two limit blocks 206 are squeezed inside the rectangular groove 306, and then the position of the connecting column 202 can be adjusted downward;

[0032] When the upper plate 101 needs to be adjusted upward, it is only necessary to lift the upper plate 101 so that the upper plate 101 drives the connecting column 202 to move, and then the limit block 206 moves, and then the second inclined surface 305 moves. Through the setting of the second inclined surface 305, when the connecting column 202 is lifted, the snap-in hole 203 squeezes the second inclined surface 305, so that the two corresponding limit blocks 206 are close to each other, so that they are unlocked. When it is adjusted to the appropriate position, the limit spring 207 works, and then the limit spring 207 squeezes the two limit blocks 206, so that the limit blocks 206 enter the inside of the snap-in hole 203 at the appropriate position.
