Abstract: A transverse adjustment mechanism for a bilateral half-spring type load-carrying head is installed in the casing of the load-carrying head of the lifting unit of a pit type unwheeling machine, fixedly connected with the casing, directly connected to an adjustment unit at the end of the load-carrying head, and installed on a lead screw of the adjustment unit. The transverse adjustment mechanism includes an adjusting nut, an adjusting nut guide, a guiding tube, and a guiding sleeve, a nut mounting plate, a flange plate, a compression spring and a sliding shaft. The invention is currently applied to the transverse adjustment of the no-loading heads and transverse fine adjustment of the load-carrying heads of a China Railway High-speed (CRH) train. The structure is reliable and practical, safe, convenient and energy-saving to use and satisfies the demand for the synchronous lifting operation of the entire CRH train of the compatible pit type unwheeling machine.

Abstract: The present invention relates to a disposable reaction cuvette segment for use in full automatic chemistry analyzers, which is a curved cuvette segment (1) comprising at least three open-ended cuvettes (11). Connecting webs (12) are arranged on the top surface between every two adjacent cuvettes (11) and on the upper part of the front and back sides of the cuvettes. The lower part of the cuvette (11) is an optical surface (13). Two fixing protrusions (15) of the same height arranged at the same level are provided vertically down on the top of the inner side of the curved cuvette segment (1), and inside each of these protrusions there is set a vertically oriented mounting hole (16) having a round or tapered shape. As compared with the prior art, the present invention has such advantages as simpler structure, accurate positioning and convenience for installing and replacing.
