At this time, under the action of a linkage rod, a horizontal plate is driven to move up or down, and because of the first installation board and the second mounting board are hinged to the conduit.

The invention relates to the field of mechanical manufacturing, in particular to a position correcting mechanism of automobile slide bearing oil injection holes. The position correcting mechanism comprises an elastic chuck, a flexible rotating mechanism and an ejecting cylinder. The elastic chuck is sleeved with slide bearings. The rotating center of the flexible rotating mechanism coincides with the central axes of the slide bearings. The ejecting cylinder is arranged at the lower portion of the flexible rotating mechanism. The position correcting mechanism is used for correcting the positions of the slide bearings, so that the positions of the oil injection holes of the slide bearings face the uppermost portion, and the positions are well prepared for the subsequent chamfering procedure of the oil injection holes. The position correcting mechanism is simple in action and conducts only two actions through a rack cylinder and the ejecting cylinder. The position correcting mechanism is simple in action, the requirement for an electrical control system is lowered, and meanwhile the reliability of a system is improved and the failure rate of the system is decreased.

The invention discloses a building cleaning system and cleaning method. The cleaning system comprises lifting devices and cleaning modules (4) connected with the lifting devices, and the cleaning modules (4) are driven by the lifting devices to move up and down; and the cleaning system further comprises annular ropes (3) arranged on the outer wall of a building in a sleeving mode, and the annular ropes (3) are connected with the cleaning modules (4). According to the cleaning method, the cleaning modules (4) are adopted to conduct cleaning simultaneously, and a computer device is used for coordinated controlling to avoid interference. According to the building cleaning system and cleaning method, the annular ropes (3) and the cleaning modules (4) are subjected to the reverse force from the building, so that the cleaning modules (4) always maintain sufficient contact force with the building, and the desired cleaning effect can be achieved; and meanwhile, the cleaning efficiency is improved greatly through multi-module coordinated cleaning.

The invention discloses a medical medicine cup cleaning and disinfecting machine. The medical medicine cup cleaning and disinfecting machine comprises a device body with a cleaning cavity in the rightside end face, wherein the right side wall of the cleaning cavity communicates with the right side end face of the device body and is provided with a cleaning inlet; supporting bases are fixedly arranged at the positions, positioned below the cleaning inlet, of the right side end face of the device body in a front-back corresponding manner; and a first belt wheel is rotationally arranged betweenthe supporting bases in front-back corresponding manner through a first rotation shaft. According to the cleaning device, a cleaning liquid mixed with water is used for flushing a medical medicine cupfirstly, then a cleaning brush is used for brushing, residual dirt is flushed through purified water, and through the combined cleaning manner, the medical medicine cup can be efficiently cleaned.

The invention discloses a rope feeding device, which comprises a shell. The shell is provided with a rope through hole; a support is arranged in the shell; a rope pressing device is arranged in the rope through hole. A certain force is applied to a mooring rope by arranging the rope pressing device, and therefore, the mooring rope between the rope feeding device and a winch is prevented from being too loose when takeup is performed by the winch.

The invention discloses a label printer and a label accurate positioning printing method thereof. The label printer comprises an outer shell, a label box installed in the outer shell, a power mechanism and a control mechanism which are used for controlling paper outlet of the label box and take-up and pay-off of thermal transfer ribbons, and a printing head used for achieving label printing. According to the invention, internal spaces of the label box are reasonably planned, and a linear label paper outlet channel and a label rollback release space are arranged, so that smooth paper feeding and discharging are guaranteed, and label paper is prevented from wrinkling in a rollback process; through improvement of a gear transmission system, forward and reverse rotation of a gear can be realized through the same motor, so that normal printing of the label paper and the thermal transfer ribbons can be realized, rollback of the label paper and the thermal transfer ribbons can also be realized, waste of the label paper and the thermal transfer ribbons is avoided, and the material utilization rate is improved; and through arrangement of a photoelectric sensor with a reflecting prism, an occupied space of the label box is reduced, and favorable conditions are provided for realizing a miniaturized label box. The invention is compact in structure, high in space utilization rate, accurate and reliable in printing and wide in application range.
