2results about How to "Prevent sliding back and forth" patented technology

This utility model relates to the field of motor manufacturing technology, specifically a signal conversion module with an anti-detachment connection structure. It includes a signal conversion module body, a protective tube A, and a protective tube B. The top and bottom of the signal conversion module body are respectively provided with anti-wear covers. Wiring grooves A and B are respectively provided on both sides and the front side of the signal conversion module body. Protective tubes A and B are respectively provided on one side of wiring grooves A and B. By providing protective tube A, the connecting wire can be prevented from sliding back and forth within wiring groove A, avoiding friction and wear. The anti-wear ring prevents wear between the wire interface and the edge of wiring groove B. Rotating and tightening bolt B moves the upper positioning plate downwards along the guide groove, cooperating with the lower positioning plate to press the connecting wires of different specifications and thicknesses on both sides, thereby improving the positioning effect of the mating wires and preventing wire ends from loosening.

This utility model discloses a mine car stopper to prevent runaway mine cars, relating to the technical field of mining engineering. It includes a track body, with a locking plate slidably connected to the upper surface of the track body. A car stopper, arc-shaped, is fixedly connected to the upper surface of the locking plate. This utility model has a reasonable design structure. Through the cooperation of the locking plate, sliding rod, fixing plate, and spring, when using the device, after an emergency stop, pulling the handle moves the two fixing plates away, clamping them onto the outer surface of the track body, allowing for quick installation of the car stopper. This solves the problem that currently used runaway mine car prevention devices mostly require fixing to the track, have complex structures, high costs, and are inconvenient to carry. This makes it difficult to effectively prevent mine cars from sliding in a timely manner after an emergency stop, posing a serious safety hazard.
