The present invention relates to a linear actuator comprising a console, an outer tube connected to the console, an electric motor, a transmission, and a spindle in connection with the transmission. The linear actuator comprises a spindle nut on the spindle and an inner tube connected to the spindle nut. The spindle nut and the inner tube are guided inside the outer tube. The linear actuator comprises a control box which is connected to the console by means of a snap connection. The linear actuator further comprises an end stop arrangement having an end switch for each direction of movement of the spindle nut. An object underlying the invention is to provide a simpler connection of the control box to the linear actuator. A further object is to provide a less complex construction of the end stop arrangement of a linear actuator. To this end, the control box is connected to the console by means of a snap connection. Further, the linear actuator comprises a sliding element arranged between the spindle nut and the end switches, and where the sliding element is actuated by the spindle nut.

Linear actuator

A linear actuator is described comprising an actuator housing, a driven element moveable at a front end of the linear actuator and a mounting () at a rear end of the linear actuator, wherein the mounting () comprises two arms () and an accommodation space () between the two arms (). The object underlying the invention is to provide a linear actuator which can easily be mounted with its rear mounting. To this end, at least one arm () is provided with a lever () which is rotatable about an axis between an open position and a closed position, wherein in the closed position, an end portion () of the lever () at least partly closes an opening () between the two arms () and in the open position makes the opening () accessible.

The present invention relates to a linear actuator comprising a console (), an outer tube connected to the console, an electric motor, a transmission, and a spindle in connection with the transmission. The linear actuator comprises a spindle nut on the spindle and an inner tube connected to the spindle nut. The spindle nut and the inner tube are guided inside the outer tube. For mounting the linear actuator, a rear end is equipped with a rear mounting () and a front end of the inner tube is equipped with a front mounting. In such a linear actuator the rear mounting should be mounted to the housing in a simple manner. To this end, the console () comprises a first fixing geometry () having a number of first fingers () distributed in the circumferential direction around the axis and the rear mounting () comprises a second fixing geometry () as negative form of the first fixing geometry, wherein the first fixing geometry and the second fixing geometry form an overlapping region.
