Description
Technical field
The utility model relates to Physical Experiment technical field of tools, particularly relates to a kind of portable folding leverage ruler.
Background technology
In physics, the hard objects can rotated around point of fixity is under force called lever, lever principle is one of important content of courses, and therefore lever used for physics teaching seems particularly important in teaching process.Existing leverage ruler can not fold, and area occupied is larger, and carries inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable in length, physics teaching portable folding leverage ruler easy to carry, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model is by the following technical solutions:
A kind of portable folding leverage ruler, comprise main lever chi, described main lever chi two ends are connected with retractable lever ruler, and the width of described retractable lever ruler is less than the width of main lever chi, and described retractable lever ruler can insert main lever chi inside by staggered floor; Described retractable lever ruler is provided with movable slider, and the width of described movable slider is greater than the width of described main lever chi, and described retractable lever ruler both sides are provided with baffle plate, are provided with balance nut outside described baffle plate; Described movable slider is connected with hook by connecting link; Described main lever chi is connected with expansion link by turning axle, and described expansion link is arranged on fixed bar, and described fixed bar connects base for supporting.
Preferably, described retractable lever ruler has 2, and it is inner that staggered floor is arranged on described main lever chi.
Preferably, described balance nut has 2, is separately positioned on the two ends of described retractable lever ruler.
Preferably, described hook can hang counterweight.
Preferably, described main lever chi and retractable lever ruler are provided with scale.
Compared with prior art, the beneficial effects of the utility model are: main lever chi two ends are provided with retractable lever ruler, and it is inner that retractable lever ruler can take in main lever chi, also can pull out; The fixed bar of support is provided with expansion link, and therefore the height of support can freely adjust; The setting of turning axle, makes main lever chi and fixed bar be folded into straight line, easy to use, is easy to carry.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, a kind of portable folding leverage ruler, comprise main lever chi 1, described main lever chi 1 two ends are connected to retractable lever ruler 2, the width of described retractable lever ruler 2 is less than the width of main lever chi 1, and described retractable lever ruler 2 can insert main lever chi 1 inside by staggered floor; Described retractable lever ruler 2 is provided with movable slider 3, and the width of described movable slider 3 is greater than the width of described main lever chi 1, and described retractable lever ruler 2 both sides are provided with baffle plate 4, are respectively equipped with balance nut 5 outside described baffle plate 4; Described movable slider 3 is connected with hook 8 by connecting link 7, and described hook 8 can hang counterweight 9, and described main lever chi 1 is connected with expansion link 10 by turning axle 6, and described expansion link 10 is arranged on fixed bar 11, and described fixed bar 11 is connected with base for supporting 12.
During experiment, extendable lever 2 chi at main lever chi 1 two ends is pulled out, expansion link 10 is pulled out from fixed bar 11, adjusts the height of support.Mobile movable slider 3, and directly on hook 8, increase and decrease counterweight 9, main lever chi 1 and retractable lever ruler 2 are provided with scale, directly can read the arm of force and counterweight 9 quality, be convenient to the explanation of lever principle.After finishing using, retractable lever ruler 2 staggered floor is taken in main lever chi 1 inner, it is inner that fixed bar 11 taken in by expansion link 10, rotates turning axle 6, makes fixed bar 11 and main lever chi folding 6 build up straight line, easy to use, is easy to carry.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
