The invention relates to an anti-fogging self-cleaning laparoscope which is characterized in that a transparent glass sheet is fixedly arranged at the outer end of an objective lens at the far end of the laparoscope, and a closed carbon dioxide gas groove is formed in a gap between the transparent glass sheet and the objective lens; an air inlet pipeline is fixed along the inner wall of an outer tube of the laparoscope, a corresponding air inlet hole is formed in the near end of the air inlet pipeline, and the far end of the air inlet pipeline penetrates through the objective lens and extends into the carbon dioxide gas groove; a gas outlet pipeline is fixed along the inner wall of the outer tube of the laparoscope, the far end of the gas outlet pipeline extends into the carbon dioxide gas groove, and the near end of the gas outlet pipeline exhausts gas through a gas exhaust hole; and the air inlet is externally connected with a carbon dioxide air source. The laparoscope solves the technical problems that an existing laparoscope is prone to causing fogging of an objective lens and infection of tissue fluid in a minimally invasive abdominal surgery, consequently, the surgical field is blurred, and surgical operation needs to be interrupted due to the fact that a real-time processing function does not exist.

This invention relates to the field of flue gas separation technology, specifically to a rare earth electrolysis furnace flue gas separation and recovery device, including a base, a rare earth electrolysis furnace, a lifting arm, an anode component, a cathode component, a feeder, a flue gas separator, a purging and material removal mechanism, and a dust collector. The rare earth electrolysis furnace and the feeder are installed on the base. The lifting arm carries the anode component, which works in conjunction with the cathode component to achieve the electrolysis reaction. The feeder transports rare earth raw materials. The flue gas separator separates fluorides and large particulate impurities in the flue gas through a coarse filter and a pluggable ceramic fluoride adsorption plate. The purging and material removal mechanism purges and recovers fluorides. The dust collector removes fine dust. This invention solves the problem of fluoride separation in electrolysis furnace flue gas.

The utility model discloses a retractable dividing strip, relates to the technical field of roof concrete protective layer dividing strips, and solves the problems that the existing roof dividing strip is not firmly fixed, a stress counteracting structure is easy to damage to cause leakage or failure, and the bearing capacity of a vertical supporting structure is limited. The utility model provides a retractable dividing strip which comprises an upper strip body, a vertical supporting structure, an elastic component and a lower strip body. The vertical supporting structure comprises two vertical strip bodies, the two vertical strip bodies are arranged in parallel, and the vertical strip bodies are fixedly connected between the upper strip body and the lower strip body and are of a symmetrical structure; and the elastic part is filled between the two vertical bar bodies. The upper strip body, the vertical strip body and the lower strip body are all made of aluminum alloy materials, and the elastic component is made of PE foam cotton. The telescopic structure designed by the utility model can counteract stress and enhance the supporting force and the fixing effect of the dividing strip, and the structural design is attractive and practical.

The utility model discloses a kind of universal buckle connecting pieces, including cavity, transmission mechanism, tensioning mechanism and locking mechanism, transmission mechanism, tensioning mechanism and locking mechanism are all located in cavity, transmission mechanism is connected with tensioning mechanism, and tensioning mechanism is connected with locking mechanism.Cavity is composed of first shell and second shell, transmission mechanism is internal hex gear, tensioning mechanism is multi-tooth transmission bolt, locking mechanism is guiding locking column, guiding locking column is equipped with direction-changing rail guide groove, and cooperate with the hemispherical convex point of second shell.When using, after plate piece is equipped with universal buckle, it is slid into side plate clamping groove, operating transmission mechanism drives tensioning mechanism, so that locking mechanism moves and rotates 90 degrees and locks.The connecting piece can be quickly installed and disassembled, reused, reduce maintenance cost, suitable for various metal cabinets, realize plate piece stepless adjustment lock, improve aesthetic degree and installation efficiency.
