Abstract
The utility model provides a kind of teaching inclined-plane to it is characterized in that comprising inclined-plane, plane, hinge and cushion block, and described cushion block need to be raised one end by hinge and inclined-plane and be connected, and described cushion block quantity is more than 1; It is oblique angle that described inclined-plane does not need one end downside of raising, inclined-plane is raised afterwards and contacted with plane upper surface; Increase both sides, described inclined-plane, and dolly cannot be skidded off.The utility model is simple in structure easy to use, can reach better teaching efficiency.
Description
Technical field
The utility model relates to teaching equipment field, is specifically related to a kind of teaching inclined-plane.
Background technology
Junior middle school imparts knowledge to students in the time saying Newton first law, with testing on an inclined-plane, slide the dolly coming from differing heights, coasting distance difference in the plane, conventional teaching equipment is exactly a rectangular plate, while regulating height, adds cushion block in a side of plate, regulates trouble, and dolly can slave plate when gliding side skid off, make the failure of an experiment.
Summary of the invention
The utility model is to solve existing teaching inclined-plane to regulate problem inconvenient and that dolly skids off, and a solution is provided.
The technical solution adopted in the utility model is: a kind of teaching inclined-plane is characterized in that comprising inclined-plane, plane, hinge and cushion block, and described cushion block need to be raised one end by hinge and inclined-plane and be connected, and described cushion block quantity is more than 2.
It is oblique angle that described inclined-plane does not need one end downside of raising, inclined-plane is raised afterwards and contacted with plane upper surface.
Increase both sides, described inclined-plane, and dolly cannot be skidded off.
The beneficial effects of the utility model are: the utility model is simple in structure easy to use, can reach better teaching efficiency.
Brief description of the drawings
Fig. 1 structural drawing of the present utility model;
Fig. 2 the utility model inclined-plane sectional view.
Reference numeral: 1-inclined-plane, 2-plane, 3-hinge, 4-cushion block.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.A kind of teaching inclined-plane is characterized in that comprising inclined-plane 1, plane 2, hinge 3 and cushion block 4 as shown in Figure 1, and described cushion block 4 need to be raised one end by hinge 3 and inclined-plane 1 and be connected; It is oblique angle that described inclined-plane 1 does not need one end downside of raising, inclined-plane 1 is raised afterwards and contacted with plane 2 upper surfaces.
Increase 1 both sides, inclined-plane as shown in Figure 2, and dolly cannot be skidded off.
Below be only specific embodiments more of the present utility model; above-mentioned concrete structure can not be interpreted as it is to restriction of the present utility model; in fact; specific embodiment of the utility model has a variety of, within every insubstantial modifications of in the utility model design, it being made all falls into protection domain of the present utility model.
