4results about How to "Avoid wasting manpower" patented technology

This utility model discloses a liquid nitrogen insulated container device with detachable centrifuge tubes, including an insulated container body. An iron column is fixedly installed inside the insulated container body. A first slot is formed at the upper end of the iron column, and second slots are formed on both sides of the first slot. A connecting ring is fixedly connected to the outside of the iron column. A first locking block is fixedly installed on the inner side of the connecting ring. An installation rod is installed on the front of the outer wall of the connecting ring. A buckle is fixedly installed at the front end of the installation rod, and a support ring is fixedly installed inside the buckle. An anti-slip pad is fixedly installed at the lower end of the support ring. In this utility model, the centrifuge tubes and the insulated container are connected by buckles, allowing for easy disassembly and cleaning of the inside of the insulated container. The use of buckles of different sizes ensures that the size of the centrifuge tubes can be adjusted according to the sample size during the experiment. The centrifuge tubes can be installed inside the insulated container via buckles, preventing the need for external force to stabilize them during the experiment and avoiding wasted manpower.

The utility model relates to the technical field of air suction boxes, in particular to a sweeping scraper. Comprising a rotating shaft, a mounting seat, a scraper and an angle adjusting assembly, the rotating shaft is mounted beside an air inlet filter screen of the air suction box, is connected with the mounting seat and is used for driving the mounting seat to swing; one end of the scraper blade is hinged with the mounting seat, and the other end of the scraper blade is used for scraping flyings and short fibers on an air inlet filter screen of the air suction box; the angle adjusting assembly is used for adjusting the size of a gap between the scraper and the air inlet filter screen of the scraping air suction box, one end of the angle adjusting assembly is slidably connected with the mounting base, and the other end of the angle adjusting assembly is slidably connected with the scraper. The cleaning scraping blade is simple in structure and easy to use, the size of the gap between the scraping blade and the air inlet filter screen of the air suction box can be adjusted, and therefore the scraping effect of the scraping blade on flyings and short fibers on the air inlet filter screen of the air suction box is guaranteed, and the using effect of the air suction box is improved.

The utility model relates to the technical field of whole pipe feeding of laser pipe cutting machine, especially to a kind of quick feeding equipment, including pipe support and three groups of stock bin frame and the feeding rack of installation in the front of stock bin frame, the pipe support is provided with the head alignment mechanism of alignment pipeline, the stock bin frame and feeding rack are all provided with the feeding mechanism of quick feeding. The utility model is by being provided with feeding mechanism, can realize full-automatic autonomous feeding, without manual assistance, liberates labor, avoids the human waste of the cooperation of many people when artificial feeding, and simultaneously automatic operation reduces the security risk brought by manual operation, guarantees work safety, reduces production cost, improves production efficiency, by being provided with head alignment mechanism, the position of pipe material can be adjusted, so that the pipe material stored in stock bin frame is aligned at one end, it is convenient for laser pipe cutting machine to accurately clamp material, and feeding position can also be adjusted, adapt to pipe material of different lengths.

A drainage bag capable of quantitatively collecting liquid specimens belongs to the technical field of medical instruments, is used for collecting specimens and can quantitatively and automatically stop. According to the technical scheme, a liquid leading-in cylinder is placed in a drainage bag, the upper end of the liquid leading-in cylinder is connected with the periphery of a liquid inlet hole of the drainage bag, the lower end of the liquid leading-in cylinder is closed, small communicating holes are evenly distributed in the bottom face of the liquid leading-in cylinder, positioning scales are arranged on the outer wall of the liquid leading-in cylinder, and the lower portion of a quantitative adjusting pull tube is placed in the liquid leading-in cylinder. The upper portion of the quantitative adjusting pull tube is connected with the lower end of the drainage hose, the hollow piston is installed at the lower end of the quantitative adjusting pull tube, the outer wall of the hollow piston is in tight sliding fit with the inner hole wall of the liquid introduction cylinder, the closed floating ball is placed below the hollow piston, and the diameter of the closed floating ball is larger than that of a center through hole of the hollow piston. The quantitative liquid sample collector is simple in structure and convenient to use, liquid samples can be quantitatively collected, the work of staring and controlling the drainage amount is relieved, and the risk of excessive drainage easily caused is avoided.
