The utility model discloses a kind of universal coupling based on card column type telescopic cross axle, including card column type cross axle, the telescopic cavity is evenly provided in the inside of card column type cross axle four corners, telescopic column is installed in the telescopic cavity, and telescopic spring is fixed between the telescopic column and the card column type cross axle.Affinity effect lies in: the utility model is by setting a group of by operating mechanism of push block, telescopic sealing plate, locking bolt and positioning hole composition, in assembling process, by push block telescopic column is moved to compression to telescopic spring, make it easy to assemble, and telescopic sealing plate is sealed to cavity at the same time again without affecting the moving performance of push block, and it can be realized to the fixing of telescopic column after adjustment by locking bolt and positioning hole combination, on the one hand, it is convenient for staff to assemble operation, and safety factor is high, on the other hand, it can be guaranteed to avoid the influence of telescopic spring on transmission performance in use process, guarantee its use performance.

The utility model discloses a positioning device for rotor processing, which relates to the technical field of rotor processing and comprises two bases, transverse electric guide rails are arranged on the two bases, sliding rods are connected to the output ends of the transverse electric guide rails, first bidirectional electric guide rails are arranged on the tops of the sliding rods, and second bidirectional electric guide rails are arranged on the tops of the first bidirectional electric guide rails. Wheel carriers are arranged on the two sides of the output end of the first bidirectional electric guide rail, the distance between the supporting wheels on the left side and the right side can be adjusted through the transverse electric guide rail, then the distance between the supporting wheels on the front side and the rear side can be adjusted in cooperation with the first bidirectional electric guide rail, and therefore the supporting wheels on the periphery can support rotors of different lengths. And through an electric telescopic rod, a lifting electric guide rail and a two-way electric guide rail II, a pressing wheel is matched with a supporting wheel to position the rotor, and the two ends of the rotor are in contact with a certain number of balls respectively, so that the rotor can keep stable rotation during rotation, and the conditions of left-right, up-down and front-back displacement are avoided.

The utility model discloses a kind of foldable X-ray photography devices, it is related to by making radiation penetrate material technical field field of technology.A kind of foldable X-ray photography device, including folding support frame and transmitter, transmitter is installed on folding support frame, protection component, protection component is located on transmitter, protection component includes winding drum, two positioning frames, rotating shaft, shielding cloth, two sliding rods and two connecting sliders, winding drum is fixedly connected on the side of transmitter, two positioning frames are all fixedly connected on the side of winding drum, two positioning frames are respectively fixedly connected on the two sides of transmitter, by protection component, when equipment is idle, can let shielding cloth completely cover transmitter, effectively block dust adsorption, maintain optical lens clean, ensure X-ray penetration smooth, guarantee imaging quality always stable and clear, and while providing effective protection, not take too much space, and do not affect equipment folding and moving, can easily adapt to different medical scenarios.

The utility model belongs to the field of seedling raising, and particularly relates to a layered automatic light supplementing garden seedling raising frame which comprises a seedling raising frame body, a partition plate is fixedly connected to the interior of the seedling raising frame body, and a seedling raising plate is arranged on the top of the partition plate. The light supplementing assembly is arranged at the bottom of the partition plate; the wire arranging assemblies are arranged on the left side and the right side of the seedling raising frame body. The light supplementing lamp is arranged below the top wall of the partition plate, and then the height of the light supplementing lamp can be adjusted to adjust the illumination intensity so as to adapt to plants in different growth periods, so that the seedling raising period of the plants is prolonged, and the survival rate of the plants is improved; and in addition, wires of the light supplementing lamps are arranged through the vertical rods and the transverse rods, so that the wires are neatly stacked in the transverse rods and the vertical grooves, at the moment, the wires do not affect stacking and moving of the plants, and electrical hidden dangers are also avoided.

The application discloses a steel structure inner cavity magnetic wall-climbing robot welding seam defect positioning device and method, belongs to the technical field of defect positioning, solves the problem that the existing wall-climbing robot cannot effectively adsorb and stably travel on the inner cavity of a complex-shaped steel structure, and leads to insufficient defect detection adaptability, and comprises a positioning device main body, a magnetic travel mechanism and a self-cleaning defect positioning mechanism, wherein the magnetic travel mechanism comprises a combined magnetic wheel, a self-adaptive protection assembly and a damping reset assembly; in the application, the combined magnetic wheel, the wheel driving motor and the self-adaptive protection assembly are cooperatively matched to non-rigidly fix the combined magnetic wheel, and the combined magnetic wheel is hung in a robot moving seat through the self-adaptive protection assembly; when the robot encounters a recess or a protrusion of an inner cavity wall surface, the corresponding combined magnetic wheel will self-adaptively float up and down, thereby actively adhering to the wall surface, so as to adapt to the inner cavity wall of a steel structure of different shapes and ensure that the robot can be stably adsorbed on the inner wall in the whole process.
