The invention relates to a safe position-limiting mechanism for an automatic rotary table conveying device. The safe position-limiting mechanism for the automatic rotary table conveying device comprises a stopper arranged on a rotary table roller way, and a pressing plate arranged on a conveying roller way, wherein the stopper comprises two sleeves arranged on a bottom plate of the rotary table roller way; support rods are inserted into the two sleeves; one ends of the two support rods are connected with the bottom plate of the rotary table roller way through springs; the other ends of the twosupport rods are connected with the bottom part of one long strip-shaped stopper block; the top part of the stopper block is located above the rotary table roller way so as to stop a workpiece; the bottom part of the stopper block is connected with one end of a connecting rod; a rolling wheel seat and a rolling wheel are arranged at the other end, penetrating through the bottom plate of the rotary table roller way, of the connecting rod; two sections of inclined surfaces with opposite inclined directions are arranged at the bottom end of the pressing plate; the pressing plate is located on arotation path of the rolling wheel rotating along with the rotary table roller way, so that the rolling wheel contacts one section of the two sections of inclined surfaces and rolls along the inclinedsurface so as to drive the stopper block to move downwards, and the top part of the stopper block is located under the rotary table roller way; and through the elastic acting forces of the springs, the stopper block is reset after the rolling wheel and the pressing plate are separated.

The invention discloses a portal scaffold, which comprises a frame, a platform mechanism, universal wheels and a fixing mechanism; Angle α, 55°≤α≤75°, the third pole is set parallel to the ground, the adjacent first pole and the second pole are fixedly connected by the third pole to form the door frame A, and the two adjacent first poles pass through the third The bars are fixedly connected to form a door frame B, and two adjacent second bars are fixedly connected by a third bar to form a door frame C. Any two door frames A are parallel to each other, and the door frame B and door frame C form an angle β, 0°≤ β≤55°; in the platform mechanism, the first flat plate, the second flat plate and the third flat plate are respectively hinged to the bracket; in the fixed mechanism, the sliding rod moves up or down to the uppermost or lowermost part The wheels or support bases are in contact with the ground. The invention has a simple structure and is a platform structure, so that the scaffolding is not easy to fall over, and the universal wheel is not easy to roll when in use.

The invention relates to a vehicle comprising at least one vehicle door or vehicle panel which forms a first element and a vehicle body which forms a second element. The vehicle door or vehicle panel is attached to the vehicle body in a pivotal manner and can be secured to the vehicle body in the closed state by means of at least one lock which interacts with a closing element. The vehicle also comprises an impact damping arrangement (10, 30, 40, 100-700) for damping impacts between the vehicle body and the vehicle door or vehicle panel when the vehicle door or vehicle panel is being closed. The damping arrangement (10, 30, 40, 100-700) has a damping device that is arranged between the vehicle body and the vehicle door or vehicle panel and has a first movement portion which undergoes damping and a second movement portion which does not undergo damping. The invention is characterized in that the impact damping arrangement (10, 30, 40, 100-700) is designed such that, when the vehicle door or vehicle panel is moved towards the vehicle body, said movement passes through the first movement portion first and then through the second movement portion. The first movement portion is arranged such that the movement along the first movement portion ends when the lock and the closing element come into contact with each other.
