Abstract
The utility model relates to a mechanics teaching aid. At present, there is no good teaching aid for showing how the pressure of the water on a container changes when overweight and weight loss are being demonstrated. The utility model provides the mechanics teaching aid so as to solve the deficiency in the prior art. The mechanics teaching aid can show how the pressure of the water on the container changes when overweight and weight loss are being demonstrated. The technical scheme adopted in the utility model for solving the technical problem is that: the mechanics teaching aid comprises a fixed pulley (1), the rotation shaft of which is in the horizontal direction and a rope (2) which straddles in the groove of the fixed pulley (1). The mechanics teaching aid is characterized in that: one end of the rope (2) is connected with a deformation barrel (3). The structure of the deformation barrel (3) is that: the upper end of a round barrel (31) is opened, the lower end is provided with a rubber membrane (33) which is fixedly connected to the edge of the round barrel and the round barrel (31) is loaded with water (32). The utility model provides the new mechanics teaching aid.
Description
Technical field
The utility model relates to a kind of mechanical teaching aid.
Background technology
Existing mechanical teaching aid is very abundant, still, and concerning the creative teacher of richness, still can create that the teaching aid making new advances take is better Teaching Service, such as existing teaching aid is overweight and weightless to demonstrating time, how water changes the pressure of container, still lacks at present good teaching aid.
Utility model content
In order to solve the deficiencies in the prior art, the utility model proposes a kind of mechanical teaching aid, the utility model can be demonstrated overweight and weightless time, and how water changes the pressure of container.
The utility model solves the technical scheme that its technical matters adopts: a kind of mechanical teaching aid, comprise: turning axle fixed pulley in the horizontal direction, the rope across in fixed pulley groove, is characterized in that: one end of rope connects a deformation tube, and be connected to the upper end of deformation tube
The structure of deformation tube is such: cylinder upper end open, there is the rubber membrane that is fixedly connected on cylinder edge lower end, and in cylinder, has taken up water.
The utility model is that mechanical teaching aid proposes a kind of new technical scheme.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model partial structurtes schematic diagram.
1-fixed pulley in figure, 2-rope, 3-deformation tube, 31-cylinder, 32-water, 33-rubber membrane.
Embodiment
Below in conjunction with accompanying drawing, design and use of the present utility model are further illustrated.
Referring to accompanying drawing 1, it is structural representation of the present utility model, a kind of mechanical teaching aid, comprise: turning axle fixed pulley (1) in the horizontal direction, across the rope (2) in fixed pulley (1) groove, it is characterized in that: one end of rope (2) connects a deformation tube (3), and be connected to the upper end of deformation tube (3)
Referring to accompanying drawing 2, it is the structural representation of the utility model deformation tube (3), the structure of deformation tube (3) is such: cylinder (31) upper end open, there is the rubber membrane (33) that is fixedly connected on cylinder edge lower end, and in cylinder (31), has taken up water (32).
Various equivalent modifications should be known: can be with the fixing fixed pulley (1) of iron stand.
Various equivalent modifications also should be known: rope (2) strides across fixed pulley (1), and the athletic meeting of rope (2) drives fixed pulley (1) rotation.
Using method: one end of rope (2) connects deformation tube (3), the other end of rope (2) is with holding, with hand, suddenly pull rope, allow deformation tube (3) that overweight phenomenon occurs, can see that rubber membrane (33) deformation increases, if control the motion of hand, allow the motion conditions of deformation tube (3) be weightless, so, can see that rubber membrane (33) deformation reduces.
The utility model provides a kind of new technical scheme for mechanical teaching aid.
Claims (1)
1. a mechanical teaching aid, comprising: turning axle fixed pulley (1) in the horizontal direction, and the rope (2) across in fixed pulley (1) groove, is characterized in that: one end of rope (2) connects a deformation tube (3), and is connected to the upper end of deformation tube (3),
The structure of deformation tube (3) is such: cylinder (31) upper end open, there is the rubber membrane (33) that is fixedly connected on cylinder edge lower end, and in cylinder (31), has taken up water (32).
