Foldable foot stool

Abstract

A collapsible tripod, comprising a bearing, a first bracket unit, a second bracket unit, a linkage unit and a locking unit, the first bracket unit and the second bracket unit can be used relative to the The bearing member pivots, and the linkage unit is pivotally connected between the first bracket unit and the second bracket unit, so that the tripod can be operated in an unfolded state or a folded state. In the folded state, the first bracket unit and the second bracket unit can be positioned relative to the carrier by using the locking unit. The overall structure is simple, easy to operate, and the support area is large when erected, and the stability is high.

Description

technical field [0001] The invention relates to a support carrier, in particular to a collapsible tripod. Background technique [0002] In order to provide convenience for the movement of general small processing machines (such as desktop sawing machines), most of the tripods carrying the machines are equipped with a foldable design for easy moving and use between different workplaces. [0003] For example, U.S. Patent No. US6942229 and US5560582 respectively provide tripods with the aforementioned functions, and the common technical features of the previous cases all include a bearing platform, a first leg pivotally arranged on one side of the bearing platform, and a first leg pivotally installed on the bearing platform. On the other side of the bearing platform and pivotally connected with the first supporting foot to form an X-shaped second supporting foot, the first supporting foot and the second supporting foot can pivot with each other, and the first supporting foot an...

Problems solved by technology

[0004] Although the above-mentioned tripod can be used for carrying equipment, and can achieve the expected purpose of folding and unfolding, the US6942229 patent must provide a guide rail inside the carrying platform, and a roller that can slide in the guide rail is provided on the top of one of the legs. However, in the US5560582 patent case, an air pressure rod must be pivotally connected between the first leg and the second leg, resulting in a more complicated structure and higher cost.

In addition, because the first leg and the second leg are pivotally connected in an X shape, if there is a large supporting area between the bottom of the first leg and the second leg, the height of the carrying platform will be insufficient.
