Abstract
The utility model relates to an improved slide rheostat, which comprises a cylindrical coil (1) and a slide arm (4), wherein fixed soldering terminals (2) are respectively arranged at two ends of the coil (1); the slide arm (4) is provided with a movable soldering terminal (3); and the slide arm (4) is installed on the coil (1) in a sliding manner. A guiding rail used as a conductor rod is eliminated, and the slide arm is led to slide in the axial direction on the surface of the coil so as to change the resistance value of a circuit. The utility model has the characteristics of simple structure, low manufacture cost and convenient use.
Description
(1), technical field
The utility model relates to the slide rheostat that a kind of middle school period Physical Experiment is used.
(2), background technology
The rheostatic travelling arm of existing glide is slidably mounted on the guide rail as stub, and described guide rail two ends are fixed on the coil cylindraceous by link, and described guide rail and described coil move towards parallel to each other.Two ends and described guide rail two ends at coil are respectively arranged with binding post.This slide rheostat structure more complicated, manufacturing cost is higher, and because complex structure is easy to the wrong lead.
(3), utility model content
Technical problem to be solved in the utility model is, a kind of improved slide rheostat is provided, and has more succinct structure and lower manufacturing cost.To overcome the defective of existing slide rheostat.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of improved slide rheostat comprises cylindric coil, is respectively arranged with a link post at the two ends of coil, also comprises travelling arm, and it is characterized in that: described travelling arm has movable binding post; Travelling arm is slidingly mounted on the described coil.
Good effect of the present utility model is: saved the guide rail as stub, but allowed travelling arm be in axial sliding to change the circuit resistance at coil surface.Has simple structure, low cost of manufacture, characteristics easy to use.
(4), description of drawings
Fig. 1 is a structural representation of the present utility model.
(5), embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises the cylindric coil 1 that is installed on the support 5, is respectively arranged with a link post 2 at the two ends of coil 1.Also comprise travelling arm 4.Described travelling arm 4 has movable binding post 3, and travelling arm 4 is installed on the described coil 1, and can endwisely slip along coil 1 on the surface of coil 1.
When using the utility model, at first wiring on each binding post along the coil 1 described travelling arm 4 that endwisely slips, can become the resistance experiment then.
Claims (1)
1. an improved slide rheostat comprises cylindric coil (1), is respectively arranged with a link post (2) at the two ends of coil (1), also comprises travelling arm (4), it is characterized in that: described travelling arm (4) has movable binding post (3); Travelling arm (4) is slidingly mounted on the described coil (1).
