The invention discloses a four-support lifting structure. The four-support lifting structure comprises a base, four trapezoidal lead screws are symmetrically installed on the surface of the base in pairs, each trapezoidal lead screw is fixedly provided with a chain wheel below the base, the four chain wheels are sequentially connected and driven through a transmission chain, the transmission chainis driven by a motor arranged on one side of the base, each trapezoidal lead screw is connected with a lifting nut above the base through threads, and the four lifting nuts are fixedly connected witha lifting platform simultaneously. According to the four-support lifting structure, the four trapezoidal lead screws are connected through one chain, simultaneous lifting of the trapezoidal lead screws is ensured, the structure is simple and compact, the total height of the structure is lower than that of similar products, the loading capacity is high, lifting is stable, the lifting stroke is high and adjustable, and the structure can adapt to various working conditions.
Description
technical field [0001] The present application relates to a lifting structure, in particular to a four-support lifting structure. Background technique [0002] The existing lifting structure is complex, and the stroke is low, and due to structural reasons, the height cannot be effectively reduced, resulting in many positions that cannot be effectively used. Contents of the invention [0003] The object of the present invention is to provide a four-support lifting structure. [0004] To achieve the above object, the present invention provides the following technical solutions. [0005] The embodiment of the present application discloses a four-support lifting structure, which includes a base, four trapezoidal screw rods are symmetrically installed on the surface of the base in pairs, each of the trapezoidal screw rods is fixedly installed with a sprocket under the base , the four sprockets are sequentially connected and driven by a transmission chain, and the transmission...
