Abstract

The invention discloses a supporting frame. The supporting frame comprises an upper supporting part and a lower supporting part. The middle of the upper supporting part is provided with a hollow tubular sliding sleeve extending downwards, the middle of the lower supporting part is provided with a hollow supporting column extending upwards, the upper portion of the sliding sleeve is radially provided with a first shaft in a penetrating mode, the two ends of the first shaft are rotationally connected with first rotating blocks, the lower portion of the supporting column is radially provided with a second shaft in a penetrating mode, and the two ends of the second shaft are rotationally provided with second rotating blocks. A treading part is pressed to drive the first rotating blocks and the second rotating blocks to rotate, the supporting frame can be supported and kept in a self-locking state, after a handle is pressed, the first rotating blocks and the second rotating blocks are reset through elastic force of a tension spring, and the supporting frame is collected.

Description

technical field [0001] The invention relates to the field of universal roller carts, in particular to a support frame. Background technique [0002] At present, the existing universal roller carts can only park on flat ground, and cannot stop the carts when encountering slopes. Therefore, a device that can park the carts on slopes is needed at present. Contents of the invention [0003] The purpose of the present invention is to provide a support frame that can be stretched up and down. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a support frame, which includes an upper support part and a lower support part, the middle part of the upper support part has a hollow tubular sliding sleeve extending downward, and the lower support part The middle part has a support column extending upwards, and the support column is movably clamped in the sliding sleeve. The upper part of the sliding sleeve is provided with ...
