Abstract

The invention discloses a double-sliding-piece slide rheostat for electrical experiments. The double-sliding-piece slide rheostat comprises a porcelain cylinder, wherein both sides of the porcelain cylinder are bonded with brackets; the surface of the porcelain cylinder is surrounded by a resistance wire; the two ends of the resistance wire are fixedly connected with separation blades; the surfaces of the separation blades are welded with lower binding posts; the lower binding posts are connected with lower terminal post caps through threads; the tops of the two brackets are separately provided with threaded holes; threaded holes are connected with metal rods through threads; the metal rods are fixedly connected with limiting pieces; the ends, close to the limiting pieces, of the metal rods are connected with threaded pipes through threads; the metal rods are in sleeve connection with slide blocks; the surfaces of the slide blocks are provided with through holes; circular rings are arranged in and bonded with the through holes; two sides of each circular ring are fixedly connected with a first sliding piece and a second sliding piece respectively; the second sliding pieces are fixedly connected with threaded rods, and the threaded rods penetrate the first sliding pieces; the tail ends of the threaded rods are connected with nuts through threads; and the surfaces of the first sliding pieces are provided with bumps. The double-sliding-piece slide rheostat of the invention is worth promotion.

Description

technical field [0001] The invention relates to a sliding rheostat, in particular to a double-slide sliding rheostat used for electrical experiments, and belongs to the technical field of electrical experiment equipment. Background technique [0002] The sliding rheostat is a circuit element, which can change its own resistance by changing its own resistance, thus playing the role of controlling the circuit. In circuit analysis, the sliding rheostat can be used as a fixed-value resistor or a variable-value resistor. [0003] When the existing sliding rheostat is used, it may be difficult for the slider to adjust the resistance, which may bring inconvenience to the resistance adjustment; in the laboratory, the phenomenon of insufficient sliding rheostat may occur, and the entire sliding rheostat is used for a single circuit. Experiment, the sliding rheostat may have unused parts, which may cause a waste of resources. Therefore, a double-sliding sliding varistor for electric...
