NEW MICROSCOPE WORKTABLE BRACKET ASSEMBLY

摘要

A microscope worktable bracket assembly comprises a worktable bracket main body (6) and two groups of upper and lower drive units. The upper and lower drive units are mounted on the worktable bracket main body, and each group of upper and lower drive units comprises a guide rail support (1), a first group of triangular guide rails (2), a second group of triangular guide rails (3), and a pin roller (4). The first group of triangular guide rails is mounted on the guide rail support, the second group of triangular guide rails is mounted on the worktable bracket main body, and the first group of triangular guide rails and the second group of triangular guide rails form a cavity. The pin roller is of a cylindrical shape and is disposed in the cavity. The upper and lower bottom surfaces of the pin roller contact a side surface of the first group of triangular guide rails and a side surface of the second group of triangular guide rails, respectively. A circumferential surface of the pin roller contacts the other side surface of the first group of triangular guide rails and the other side surface of the second group of triangular guide rails, respectively. By means of the cylindrical pin roller, a contact area with the triangular guide rails is increased, so that the drive efficacy is improved, and the triangular guide rails are not easy to be worn, so that the service life is prolonged, and an actual operation is more convenient.
