Description

Folding support convenient to fold Technical Field The utility model relates to the field of pet bath frames, in particular to a folding bracket convenient to fold. Background At present, the bath rack is designed as a whole, so that the occupied area is overlarge, and the placement is not facilitated. Disclosure of Invention In order to solve the problems, the technical scheme provides a folding bracket convenient to fold. In order to achieve the above purpose, the technical scheme is as follows: The utility model provides a folding support convenient to fold, includes connecting portion, the connecting portion both sides are articulated respectively to have first frame and second frame to enclose and establish into a space, the lower extreme both sides of connecting portion are articulated respectively to have first support frame and second support frame, first frame lower extreme articulates there is first linking arm, first linking arm articulates there is the second linking arm, the arm body of second linking arm with first support frame articulates, the second frame lower extreme articulates there is the third linking arm, the third linking arm articulates there is the fourth linking arm, the arm body of fourth linking arm with the second support frame articulates, second linking arm one end with fourth linking arm one end articulates. In some embodiments, the lower end of the first support frame is provided with a third support frame through a locking structure. In some embodiments, the locking structure includes a housing, the housing having a first cavity fixedly connected to the first support frame, a second cavity through which the third support frame passes, and a pressing member passing through the housing and the third support frame. In some embodiments, the pressing member is mounted on the housing by a snap fit. In some embodiments, a limiting portion matched with the second cavity is arranged at the end portion of the third supporting frame. In some embodiments, the hinge of the second connecting arm and the fourth connecting arm is further hinged with a first jack-up frame, and the first jack-up frame is further hinged with a second jack-up frame. In some embodiments, the locking structure comprises a shell, the shell is penetrated by a third supporting frame, a plurality of through holes are formed in the inner side surface of the third supporting frame, the shell is provided with a penetrating cylinder, the locking structure further comprises a rotatable driving shaft, and the end part of the driving shaft is provided with a plug-in part which is matched with the driving shaft and is positioned in the penetrating cylinder and can be inserted into the through holes. In some embodiments, the end part of the driving shaft is provided with a plurality of guide parts which are obliquely arranged, and the inserting part is provided with a guide groove matched with the guide parts; the plug-in part is provided with a limiting part, and a limiting groove matched with the limiting part is formed in the penetrating cylinder. In some embodiments, the penetrating cylinder is provided with a spring sleeved on the periphery of the plug-in part. In some embodiments, the drive shaft is rotationally driven by a pedal The application has the beneficial effects that: The frame on any side is turned downwards, so that the first connecting arm and the second connecting arm turn over along with the frame, the third connecting arm and the fourth connecting arm are driven to turn over along with the frame, the supporting frames on two sides are driven to turn inwards to be stored, the bath frame is completely folded, the occupied area is small, the turning efficiency is high, and the storage is flexible. Firstly, lifting up the second frame to make the first support frame as the supporting point, then turning down the second frame, at this moment, the third linking arm drives the fourth linking arm to overturn, thereby driving the second support frame to inwards overturn and accomodate, simultaneously, the second linking arm drives the first linking arm to overturn, simultaneously driving the first frame to inwards overturn and accomodate, finally accomplishing and accomodating the action, and similarly, the upset first frame also can realize overturn and accomodate.
