Abstract

The invention provides a support rotation positioning structure, which comprises a movable frame and a supporting frame rotationally installed on the movable frame through a first rotating shaft, wherein a first clamping column and a second clamping column are fixedly arranged on the supporting frame; a first clamping groove used for supporting the second clamping column from the rear side to prevent the second clamping column from moving backwards is formed in the bottom of the rear side of the supporting frame, a pedal is arranged in the movable frame, and the pedal is rotatably installed in the movable frame through a second rotating shaft. A second clamping groove used for supporting the first clamping column from the front side to prevent the first clamping column from moving forwards is formed in the upper portion of the front end of the pedal, and the rear side of the pedal is connected with the movable frame through a connecting rod assembly; wherein a torsional spring is arranged on the second rotating shaft, and the pedal is located at the limiting position of forward rotation under the action of the torsional spring. The support structure has the use state and the storage state, wherein the structure in the two states is stable and reliable and switching of the two states is convenient to operate, so that the occupied space can be reduced through storage.

Description

technical field [0001] The invention relates to a bracket rotation positioning structure, which belongs to the technical field of bracket structures for bracket wheels. Background technique [0002] As more and more equipment needs to be moved, bracket wheels are becoming more and more widely used all over the world, and casters are almost inseparable from all walks of life. In modern times, with the continuous development of science and technology, the equipment has become more and more multi-functional and high-utilization, and the bracket wheel has become an indispensable part. The bracket wheels are widely used in handcarts, mobile scaffolds, workshop trucks, etc. The existing bracket wheels for carrying goods are generally single wheels. And it generally does not have a storage function, takes up space during the transportation process, and is easily damaged. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present ...
