The invention discloses a cable fault detection device, which belongs to the technical field of cable detection, and comprises a cable fault detector, a shell, an accommodating groove formed in the top surface of the shell, and a detector adjusting mechanism and a wire core detection frame which are arranged in the shell, the cable fault detector is placed in the containing groove, a through hole is formed in one side of the containing groove, and a detection line of the cable fault detector penetrates out of the through hole and is connected with the detector adjusting mechanism; the detector adjusting mechanism comprises a vertical adjusting part, a horizontal moving part and a first conductive block, the vertical adjusting part is provided with the horizontal moving part, the horizontal moving part is provided with the first conductive block, and the detection line is connected with the first conductive block. According to the invention, the operation convenience and the detection efficiency of multi-core detection are greatly improved.

The invention discloses a voltage regulation method and system based on display frame change and speed change, and relates to the technical field of various types of display. Comprising a frame change rate detection module, a gray level voltage regulation module and a gray level voltage output module, the frame changing speed of a picture is detected through the frame changing speed detection module, the detected frame changing speed is provided for the gray level voltage adjusting module in time, and corresponding gray level voltage parameters are rapidly selected from an internal memory and provided for the gray level voltage output module, so that zero time difference is achieved from frame changing speed detection to gray level voltage output; therefore, an abnormal picture caused by slow change of the corresponding gray level voltage parameter due to data transmission of the external gray level voltage parameter by using a known method is avoided. According to the invention, an image gray level voltage regulation mode with a frame change rate detection module and a gray level voltage regulation module is used, and on the basis of shortening the gray level voltage switching time under frame change speed change and reducing an internal memory, abnormal images brought to human eyes by a display under different frame change speeds are effectively improved.

The utility model provides a telescopic moving structure for a goods shelf, and relates to the technical field of goods shelves. The telescopic moving structure for the goods shelf is installed on a goods shelf bottom support in pairs and comprises a connecting rod, a plurality of driving assemblies and a plurality of moving assemblies. The moving assembly is installed on the connecting rod, and the driving assembly is hinged between the connecting rod and a bottom support of the goods shelf and used for driving the connecting rod and the moving assembly to ascend and descend so that the goods shelf can move rapidly. The telescopic moving structure for the goods shelf is simple in structure and convenient to operate, lifting control of the trundles is achieved through linkage matching of the telescopic assemblies, the connecting rods and the moving assemblies, the goods shelf can be stably supported in use, and the trundles can be rapidly dropped to move and flexibly switched between the positioning state and the moving state when the goods shelf needs to move.
