[0040] As long as possible, the various aspects and features described and illustrated in this specification can be applied individually, and these individual aspects can be the subject of a divisional application.

[0041] As Figs. 1 to 3 The present application provides a foot pedal angle adjusting device of a foot pedal type trainer, which includes a mounting frame 1 and a training pedal 2 mounted on the mounting frame 1. The mounting frame 1 includes a first supporting rod 11 and a second supporting rod 12 fixedly connected with the first supporting rod 11, and two ends of one side of the training pedal 2 are respectively connected with the first supporting rod 11 and the second supporting rod 12, so as to fix and support the training pedal 2 through the first supporting rod 11 and the second supporting rod 12.

[0042] The second supporting rod 12 comprises a fixed rod 121 fixedly connected with the first supporting rod 11 and a telescopic rod 122 hingedly connected between the training pedal 2 and the fixed rod 121, so that when the telescopic length of the telescopic rod 122 is adjusted, the end of the training pedal 2 connected with the telescopic rod 122 is brought close to or away from the telescopic rod 122, thereby rotating the training pedal 2 about the hinge shaft of the first supporting rod 11, adjusting the angle of the training pedal 2 and meeting the training state requirements of different users.

[0043] In order to conveniently adjust the angle of the training pedal 2 and fix the position of the training pedal 2 after adjustment, an adjusting pedal 3 is arranged on one side of the training pedal 2, and an adjusting assembly 4 for controlling the telescopic rod 122 to telescope through the adjusting pedal 3 is arranged between the adjusting pedal 3 and the telescopic rod 122, so that the user can directly drive the telescopic rod 122 to telescope through the adjusting pedal 3 during training, thereby adjusting the angle of the training pedal 2.

[0044] Referring to Fig. 2 and Fig. 3 Specifically, the telescopic rod 122 comprises a first sleeve 1221 hingedly connected to the training pedal 2 and a second sleeve 1222 slidingly connected to the end of the first sleeve 1221 away from the training pedal 2, and the end of the second sleeve 1222 away from the first sleeve 1221 is hingedly connected to the fixed rod 121. The adjusting assembly 4 comprises an adjusting pin 41 slidingly connected to the outer wall of the first sleeve 1221 and a connecting piece 42 connected between the adjusting pin 41 and the adjusting pedal 3. Meanwhile, the outer wall of the second sleeve 1222 is provided with adjusting holes 1223 for the adjusting pin 41 to insert, and the adjusting holes 1223 are spaced apart along the length direction of the second sleeve 1222, so that the relative position of the first sleeve 1221 and the second sleeve 1222 can be fixed by the adjusting pin 41. One end of the adjusting pin 41 is inserted into the adjusting hole 1223, and the other end is connected with the connecting piece 42. When the adjusting pedal 3 is operated, the adjusting pedal 3 can drive the adjusting pin 41 to slide through the connecting piece 42, so that the adjusting pin 41 slides out of the adjusting hole 1223, thereby releasing the fixed relationship between the first sleeve 1221 and the second sleeve 1222. At this time, the end of the training pedal 2 connected with the second rod is pressed, thereby driving the second sleeve 1222 to slide in the first sleeve 1221, and the length of the telescopic rod 122 is adjusted.

[0045] In order to control the relative position of the adjusting pin 41 relative to the first sleeve 1221, a closed mounting cylinder 43 is fixedly connected to the outer wall of the first sleeve 1221, the opening end of the mounting cylinder 43 is fixedly connected to the first sleeve 1221, the adjusting pin 41 is located in the mounting cylinder 43, and the end of the adjusting pin 41 penetrates through the closed end of the mounting cylinder 43 and is exposed to the outside to be connected with the connecting piece 42.

[0046] Meanwhile, an adjusting spring 44 is arranged in the mounting cylinder 43 for abutting against the adjusting pin 41 to always be located in the adjusting hole 1223, and a snap ring 411 is fixed to the outer wall of the adjusting pin 41, the adjusting spring 44 is sleeved on the adjusting pin 41, the adjusting spring 44 is located between the snap ring 411 and the closed end of the mounting cylinder 43, and the two ends of the adjusting spring 44 respectively abut against the inner wall of the snap ring 411 and the closed end of the mounting cylinder 43. Under normal circumstances, the snap ring 411 is abutted against the outer wall of the first sleeve 1221 under the elastic force of the adjusting spring 44, so that the end of the adjusting pin 41 is inserted into the adjusting hole 1223.

[0047] When the adjusting pedal 3 is controlled, the adjusting pedal 3 will drive the adjusting pin 41 to slide in the mounting cylinder 43 through the connecting piece 42, so that the adjusting pin 41 presses the adjusting spring 44 to release the fixed relationship between the first sleeve 1221 and the second sleeve 1222, and facilitate the length adjustment of the telescopic rod 122, so as to realize the angle adjustment of the training pedal 2.

[0048] When the adjustment is completed, the force applied on the adjusting pedal 3 is released, and the adjusting pin 41 can be automatically inserted into the adjusting hole 1223 under the elastic force of the adjusting spring 44, so as to fix the relative position between the first sleeve 1221 and the second sleeve 1222, that is, the angle fixation of the adjusting pedal 3 can be realized.

[0049] Referring to Fig. 2 and Fig. 3 , the connecting piece 42 comprises a first connecting rod 421 fixed to the outer wall of the first sleeve 1221 and a second connecting rod 422 hinged to the end of the first connecting rod 421 away from the first sleeve 1221, the adjusting pin 41 is hinged to the middle part of the second connecting rod 422, and the end of the second connecting rod 422 away from the first connecting rod 421 extends to the training pedal 2 and is fixed to the adjusting pedal 3 located on one side of the training pedal 2. When the user presses the adjusting pedal 3, the second connecting rod 422 will be rotated around the hinge shaft of the first connecting rod 421, at this time, the second connecting rod 422 will also pull the adjusting pin 41 to slide in the mounting cylinder 43, so as to release the fixed relationship between the first sleeve 1221 and the second sleeve 1222.

[0050] And the first connecting rod 421 is fixed to the first sleeve 1221, so that when the user presses the training pedal 2 to adjust the angle of the training pedal 2, the first connecting rod 421 can slide together with the first sleeve 1221 relative to the second sleeve 1222, so as to ensure that the position of the adjusting pin 41 relative to the first sleeve 1221 is always unchanged.

[0051] Wherein, the first connecting assembly 5 is arranged between the fixed rod 121 and the telescopic rod 122 to realize the hinge connection of the two, the second connecting assembly 7 is arranged between the training pedal 2 and the telescopic rod 122 to realize the hinge connection of the two, the first connecting piece 42 and the second connecting piece 42 are the same in structure, and the difference is only that the mounting positions are different, and the utility model takes the structure of the first connecting assembly 5 as an example to illustrate.

[0052] The first connecting assembly 5 comprises two mutually parallel mounting ears 51 fixed on one side of the training pedal 2, a fixed shaft 52 fixed between the two mounting ears 51 and a rotating cylinder 53 sleeved on the fixed shaft 52, the rotating cylinder 53 is in rotating fit with the fixed shaft 52, one end of the telescopic rod 122 is fixed on the rotating cylinder 53, and the hinge connection of the telescopic rod 122 and the training pedal 2 is realized through the cooperation of the rotating cylinder 53 and the fixed shaft 52.

[0053] Meanwhile, in order to avoid that after the cooperation of the first sleeve 1221 and the second sleeve 1222 is released, a very small force applied by the user on the training pedal 2 drives the first sleeve 1221 and the second sleeve 1222 to slide a large distance, so that the adjustment amount is uncontrollable, the gas spring 1224 is also installed in the telescopic rod 122, and the two ends of the gas spring 1224 are connected to the first connecting assembly 5 and the second connecting assembly 7 respectively. Specifically, the two ends of the gas spring 1224 can be fixed to the rotating cylinders 53 of the first connecting assembly 5 and the second connecting assembly 7, so that under normal circumstances, the gas spring 1224 can give the first connecting assembly 5 and the second connecting assembly 7 a force away from each other, so that the first sleeve 1221 and the second sleeve 1222 are away from each other, when the user applies a force on the training pedal 2, the training pedal 2 will push the first sleeve 1221 and the second sleeve 1222 to be close to each other, thereby pressing the gas spring 1224, and realizing controllable adjustment.

[0054] Wherein, the connecting position of the second supporting rod 12 and the training pedal 2 can be higher than the connecting position of the first supporting rod 11 and the training pedal 2, so that the training pedal 2 rotates with the lower end as the hinge shaft; of course, the connecting position of the second supporting rod 12 and the training pedal 2 can also be lower than the connecting position of the first supporting rod 11 and the training pedal 2, so that the training pedal 2 rotates with the upper end as the hinge shaft, and the specific determination can be made according to actual needs. The utility model takes the connecting position of the second supporting rod 12 and the training pedal 2 being higher than the hinge shaft of the first supporting rod 11 and the training pedal 2 as an example to illustrate.

[0055] The implementation principle of the foot pedal angle adjusting device of the foot pedal type trainer is as follows: in normal state, the adjusting pin 41 is inserted into the corresponding adjusting hole 1223, thereby fixing the relative position between the first sleeve 1221 and the second sleeve 1222. When it is needed to adjust the angle of the training pedal 2, the adjusting pedal 3 can be pressed, at this time, the second connecting rod 422 rotates around the hinge shaft of the first connecting rod 421, thereby driving the adjusting pin 41 to be pulled out of the adjusting hole 1223, on this basis, the training pedal 2 is pressed, and the first sleeve 1221 is driven to slide relative to the second sleeve 1222 through the training pedal 2, so that the training pedal 2 rotates around the hinge shaft of the first supporting rod 11, and the adjustment of the angle of the training pedal 2 is realized. After the angle is adjusted to the appropriate angle, the force applied on the adjusting pedal 3 is released, at this time, the adjusting pin 41 is reset under the elastic force of the adjusting spring 44, so that the adjusting pin 41 is inserted into the adjusting hole 1223. The position of the first sleeve 1221 and the second sleeve 1222 can be fixed, the adjustment of the angle of the training pedal 2 is realized, and the force applied on the training pedal 2 can be released at this time, and the adjustment work of the training pedal 2 is completed.

[0056] The utility model also provides a kind of trainer, including the foot pedal angle adjusting device of the above-mentioned one kind of foot pedal type trainer.
