Abstract
Provided is a combined inclined plane, comprising an inclined plane, vertical plates, and a support body. The combined inclined plane is characterized in that the upper surface of the inclined plane is fixedly provided with a tape; two same vertical plates are symmetrically fixed into one body via an upper beam and a lower beam; the upper surface of the vertical plate is provided with a chute; one side of the chute is inscribed with scale; a support bar is inserted into the chute and is capable of sliding up and down; and two ends of the support bar are provided with threads and nuts. The utility model provides an experiment apparatus which can conveniently change the height of the inclined plane and measure the lifting height of the wood block in a visual and accurate manner.
Description
Technical field
The utility model relates to the combination inclined-plane that a kind of education experiment is used.
Background technology
Measure in the experiment of mechanical efficiency on inclined-plane in the middle school, present experiment equipment utilizes a plank (as the inclined-plane) and a wooden unit (being used for regulating highly) to come measurement mechanical efficient exactly.Distinct issues are that the height adjustment range on inclined-plane is smaller, and are not easy to measure.
Summary of the invention
Problem to be solved in the utility model is: the height that provides a kind of device can change comparatively easily the inclined-plane, and can accurately measure the height that wooden unit is raised.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of combination inclined-plane, comprise inclined-plane, riser, supporter, it is characterized in that: be fixed with tape above the inclined-plane, two identical risers are by the one that is fixed into of entablature and sill symmetry, chute is arranged above riser, one side of chute is carved with scale, and support bar inserts in chute and can slide up and down, and there is screw thread at the two ends of support bar and nut is installed.
Described combination inclined-plane is characterized in that: inclined-plane, riser, entablature, sill adopt transparent plastic processing to form.
Described the utility model has the advantages that:
The utility model provides a kind of device, can change comparatively easily the height on inclined-plane, and can intuitively measure accurately the height that wooden unit is raised.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, inclined-plane; 2, tape; 3, sill; 4, riser; 5, chute; 6, support bar; 7, nut; 8, entablature.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of combination inclined-plane, comprise inclined-plane 1, riser 4, support bar 6, it is characterized in that: be fixed with tape 2 above inclined-plane 1, two identical risers 4 are by the one that is fixed into of entablature 8 and sill 3 symmetries, chute 5 is arranged above riser 4, one side of chute 5 is carved with scale, and support bar 6 inserts in chute 5 and can slide up and down, and there is screw thread at the two ends of support bar 6 and nut 7 is installed.
Tape has intercepted certain length fixedly the time, consistent with the reading of riser 4 to guarantee height corresponding to displacement that slide block rises on the inclined-plane, has reduced experimental error.
Inclined-plane 1, riser 4, entablature 8, sill 3 adopt transparent plastic processing to form.
In practice, select certain height, screw nut 7, with fixing of the support on inclined-plane 1 and combination inclined-plane.Measure the gravity (G) of wooden unit with dynamometer, then wooden unit is placed on the bottom on inclined-plane, keep parallel with the inclined-plane with dynamometer, at the uniform velocity pull wooden unit, read the registration (F) of dynamometer.Stop drag when wooden unit arrives top (support bar), read the height (h) of this moment and the length (S) that wooden unit passes through, operate equally three times.According to formula: η=(Gh)/(FS), calculate the mechanical efficiency on inclined-plane, compare.So just completed once experiment.
The utility model can change the height on inclined-plane comparatively easily, and can intuitively measure accurately the height that wooden unit is raised.
Embodiment recited above is described preferred implementation of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineering technical personnel make the technical solution of the utility model all should fall into protection domain of the present utility model.
