[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0026] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0027] For the sake of convenience in description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0028] In addition, it should be noted that using words such as "first", "second" etc. to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.

[0029] As Figures 1 to 6 shown, a pedal rotation limiting mechanism includes a pedal 1, a limiting block 2 and a rotating shaft assembly 4; the pedal 1 is installed on a base 3 and is perpendicular to the base 3 when the pedal 1 rotates to the position of the limiting block 2; the pedal 1 and the base 3 are rotationally assembled through the rotating shaft assembly 4.

[0030] In this embodiment, the rotating shaft assemblies 4 on both sides have different structures. Only one side needs to be able to achieve rotation and pressing to open, and the other side only needs to achieve the rotation function. That is, the rotating shaft assembly 4 includes a first rotating shaft assembly 4-1 and a second rotating shaft assembly 4-2, and the pedal 1 is rotationally assembled with the first rotating shaft assembly 4-1 and the second rotating shaft assembly 4-2 through a pedal rotating arm 101.

[0031] In one embodiment, the first rotating shaft assembly 4-1 includes a first rotating shaft 401, a limit screw 405, and a limit clip mounting member 406. A first bearing 402 is sleeved outside the first rotating shaft 401, and a first rotating shaft fixing sleeve 404 is sleeved outside the first bearing 402. The limit clip mounting member 406 is located inside the first rotating shaft fixing sleeve 404 and is connected to the first rotating shaft 401 by a countersunk hexagon socket head screw. The limit clip mounting member 406 is used to mount a limit clip 407. Specifically, limit slots 411 for mounting the limit clip 407 are provided on the first rotating shaft fixing sleeve 404 and the limit clip mounting member 406. A spring 409 is sleeved on the limit screw 405 and passes through the first rotating shaft 401. The other end of the limit screw 405 passes through the limit clip 407 and is fastened by a limit nut 408. When the limit screw 405 is pressed, under the action of the spring 409, the limit clip 407 disengages from the limit slot 411, and the pedal 1 can be opened and laid flat.

[0032] In one embodiment, a wear-resistant first gasket 403 is sleeved outside the first rotating shaft 401 between the pedal rotating arm 101 and the base 3, and the first gasket 403 is fixed to the first rotating shaft fixing sleeve 404 by a countersunk hexagon socket head screw.

[0033] In one embodiment, a wear-resistant second gasket 410 is sleeved on the limit screw 405 between the limit nut 408 and the limit clip 407.

[0034] In one embodiment, the second rotating shaft assembly 4-2 includes a second rotating shaft 412. The second rotating shaft 412 is rotationally assembled through a second bearing 413 and a second rotating shaft fixing sleeve 414. The tail end of the second rotating shaft 412 has an external thread, and a nut 415 is screwed onto the external thread of the second rotating shaft 412. A gasket is sleeved on the second rotating shaft 412 between the nut 415 and the second bearing 413. In addition, a wear-resistant gasket is sleeved outside the second rotating shaft 412 between the pedal rotating arm 101 and the base 3, and the gasket is fixed to the second rotating shaft fixing sleeve 414 by a countersunk hexagon socket head screw.

[0035] Working principle:

[0036] When folding is required, directly rotate the pedal 1 until it is vertical. The limit block 2 will limit the pedal rotating arm 101. At the same time, both sides of the limit clip 407 have smooth chamfers. Under the action of the spring 409, the limit clip 407 can smoothly engage in the limit slot 411 to play a limiting role, and the pedal 1 is vertically folded up, saving the use space. When the pedal 1 needs to be used, press the limit screw 405 to disengage the limit clip 407 from the limit slot 411, and the pedal 1 can be opened and laid flat on the ground for use. This structure utilizes the central space of the pedal rotating shaft to replace the original plug-in type, improving the utilization rate of the space.

[0037] The above is the preferred embodiment of the present utility model. Those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiment. Therefore, the present utility model is not limited to the above specific embodiment, and any obvious improvements, substitutions or variations made by those skilled in the art on the basis of the present utility model all fall within the protection scope of the present utility model.
