In the above technical scheme, an L-shaped spanner is hinged below the top plate, when the top frame is in a lifting state, the limiting slide bar is limited in the clamping groove, when the top frame needs to be put down, the L-shaped spanner is slightly lifted upwards at first, so that the limiting slide bar is stirred to be separated from the clamping groove, and then the limiting slide bar slides upwards along the long slide rail, so that the top frame can be put down.

The utility model also provides a tricycle comprising the folding structure.

The utility model has the advantages and beneficial effects that:

The utility model has simple structure and is convenient for a user to realize the switching between the lowering and standing states of the frame, when the top plate is in the standing state, the sliding rod is limited in the clamping groove, when the top plate needs to be put down, the second rod is slightly lifted upwards, so that the first rod toggles the sliding rod to be separated from the clamping groove, and then the sliding rod slides upwards along the long slideway, so that the top plate can be put down.

Detailed Description

In order to make the person skilled in the art better understand the solution of the present utility model, the following describes the solution of the present utility model with reference to specific embodiments.

Example 1

A folding structure, see fig. 1, comprises a base 1, a folding assembly 9 and a limit sliding rod 8.

The folding assembly 9 comprises a bottom frame 3, a top frame 4 and a support rod assembly 5; two folding assemblies 9 are mounted on both sides of the base 1, preferably the two folding assemblies 9 are parallel to each other and symmetrical to each other; the support rod assembly 5 comprises two main support rods 5-1 and an auxiliary support rod 5-2, wherein a slide way a is arranged on any main support rod 5-1, the slide way a comprises a long slide way a2, a clamping groove a1 for positioning the limiting slide rod 8 is arranged in the long slide way a2, one end of each main support rod 5-1 is hinged to the bottom frame 3, the other end of each main support rod is hinged to the top frame 4, the limiting slide rod 8 transversely penetrates through the slide way a arranged on the two groups of folding assemblies 9, the upper end of the auxiliary support rod 5-2 is hinged to the limiting slide rod 8, the upper end of the auxiliary support rod 5-2 is embedded in a cavity of the main support rod 5-1, and the lower end of the auxiliary support rod 5-2 is hinged to the bottom frame 3.

When the top frame 4 is in the set-up state, the limiting slide bar 8 is limited in the clamping groove a1, when the top frame 4 needs to be put down, the limiting slide bar 8 is slightly lifted upwards, the limiting slide bar 8 is separated from the clamping groove a1, and then the limiting slide bar 8 slides upwards along the long slide way a2, so that the top frame 4 can be put down.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature's illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "under" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "lower" may encompass both an upper and lower orientation. The device may be otherwise positioned (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Moreover, relational terms such as "first" and "second", and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

The foregoing has described exemplary embodiments of the utility model, it being understood that any simple variations, modifications, or other equivalent arrangements which would not unduly obscure the utility model may be made by those skilled in the art without departing from the spirit of the utility model.
