3results about How to "Guaranteed scanning accuracy" patented technology

The invention discloses a double-beam laser scanning device, and belongs to the technical field of laser scanning equipment, the double-beam laser scanning device comprises a supporting seat and a supporting disc rotatably connected in the supporting seat, a fixed sleeve is fixed on the surface of the supporting disc, an adjusting sleeve is movably connected in the fixed sleeve, and a protection box is arranged at the top of the adjusting sleeve. Two partition plates are symmetrically fixed in the protection box, the opposite faces of the two partition plates are each rotationally connected with two connecting columns, two protection sleeves fixedly connected with the connecting columns are arranged between the two partition plates, laser emitters are installed in the protection sleeves, and a plurality of fans are installed in the protection box. Two moving grooves are symmetrically formed in the outer wall of one side of the protection box, and flow guide plates are movably connected into the moving grooves of the protection box. According to the double-beam laser scanning device, the scanning range can be adjusted according to scanning requirements, dust in the scanning range can be blown away in the scanning process, and the scanning precision is guaranteed.

The utility model relates to the technical field of medical equipment, and discloses a desktop type CT (computed tomography) scanning device. The driving mechanism is connected with the objective table; the ray emission module is arranged on one side of the objective table and comprises a ray source; the ray detection module is arranged on the other side of the objective table and comprises a detector, and the detector is arranged opposite to the ray source and used for receiving rays emitted by the ray source; and the at least two lifting modules are connected to the two ends of the objective table correspondingly and used for driving the two ends of the objective table to synchronously ascend and descend while the driving mechanism drives the objective table to rotate. In this way, during scanning, the objective table can drive an object to be scanned to do spiral motion in the vertical direction, spiral scanning of the object to be scanned is achieved, one-time complete scanning of a long object is achieved, meanwhile, due to the fact that the lifting modules are connected to the two ends of the objective table respectively, the two ends of the objective table can be driven to ascend and descend synchronously, and the scanning efficiency is improved. The stability of the objective table is improved, and the CT image quality is improved.

The utility model provides a kind of stable support of oral cavity external 3D scanning measuring instrument, it is related to support equipment field, including support body, the support body is used to be connected with scanner, its bottom is connected with at least three support legs, the bottom of each support leg is connected with a stable support rod respectively through a movable slot, the stable support rod can be universal rotation relative to the movable slot, the bottom of the stable support rod is equipped with the support rod bottom for contact support surface.This application connects the stable support rod that can be universal rotation through movable slot, so that fulcrum can be dynamically adjusted angle according to ground condition and impact force, realize self-adapting stability, effectively solve the problem that traditional support is inclined, collision is easy to shake and dump due to uneven stress of uneven ground, guarantee scanning accuracy and equipment safety.
