Description

Technical Field

[0001] The utility model relates to the technical field of structural beams and linear modules, and in particular to a structural beam and a linear actuator that are easy to expand. Background Art

[0002] Linear modules are widely used in the field of automation technology. They mainly include a base, a work platform, a functional module and a linear module. The linear module work platform and the functional module move to perform corresponding operations on the work platform. Traditional linear modules usually require an external independent driver to drive the entire module to work. When the external driver is connected, an intermediate connecting line is required to achieve electrical connection, which makes the space occupancy rate of the linear module too large, affecting the layout of other devices in the automation equipment. The patent with announcement number CN211371197U discloses a linear module and automation equipment. The linear module includes a housing with a concave cavity with an opening on one side, a dustproof belt for closing the opening, a screw transmission mechanism, a screw drive component for driving the screw to rotate, and a driver arranged in the concave cavity and electrically connected to the screw drive component. A sliding seat and a sensing mechanism having a guide slot; a screw transmission mechanism including a screw and a nut seat connected to the sliding seat; a guide assembly cooperating with a dustproof belt is provided in the guide slot, and the sensing mechanism includes a sensor assembly arranged on the side wall of the housing and electrically connected to the driver and a sensing sheet arranged on the sliding seat to cooperate with the sensor assembly; the linear module of the utility model is formed by fixing the sensing mechanism on the housing and the sliding seat to form an integral body by placing the driver in the concave cavity of the housing and electrically connecting it to the screw driver, so that the linear module does not need an external driver, avoids the connection of the intermediate line, and saves space. However, the housing in its scheme can only be used as the housing of the linear drive module, but it is not convenient to be used directly for building a frame structure, and a structural beam needs to be set up separately to build the frame structure of the linear drive module, which increases the setting of the external structure, the weight and volume of the structure, and the material cost. Therefore, it is necessary to invent a structural beam that can be directly used as a material for building a structure and can be built with a linear actuator. Utility Model Content
