The invention discloses a multidirectional rotation structure node for a reinforced concrete column. The structure node consists of a core reinforced concrete column and an external reinforced concrete column, wherein the core reinforced concrete column and the external reinforced concrete column consist of concrete and a reinforcement framework which are sleeved with each other from inside to outside respectively. A construction method comprises the following steps of: preparing the core reinforced concrete column; embedding the core reinforced concrete column at a preset position, and welding a core column reinforcement framework at the periphery of a prefabricated pipe after the core reinforced concrete column is arranged in position; binding an external column reinforcement framework at the preset position; casting outer column concrete on site; mounting matched constraint materials and filling materials; and binding an upper member of the reinforced concrete column, and erecting a mold to cast the concrete so as to form the integral multidirectional rotation structure node of the reinforced concrete column. The multidirectional rotation structure node has the characteristics of saving manufacturing cost, along with definite design concepts and the like, is easy to construct, is safe and reliable, is durable in use, brings great benefits to the development of economy and society in China, and has a wide application prospect.

The invention provides a lifting device for automobile engine mechanical experiments, comprising: a base, a lifting slide rail and a T-shaped block; the right side of the base is slidably connected with a group of the lifting blocks; the connection between the lifting block and the base The center is connected through the scissor mechanism; the left end face of the lifting block is axially connected with a group of the cantilever; the top of the cantilever is axially connected with a group of the rotating seat; the top of the rotating seat is tightened by threads A set of connecting blocks is fixedly connected; a set of fixing bolts is slidably connected inside the connecting block. By using the worm gear and worm transmission mechanism to drive the longitudinal rotation and horizontal rotation of the experimental parts, at the same time, the self-locking characteristics of the worm gear and worm transmission mechanism are used to prevent the automatic rotation of the parts, realize the multi-directional rotation of the experimental parts, and facilitate the all-round observation of the experimental parts And operation, easy to operate.
