When experiment starts, starting electric spark clock, make weight unsettled, weight falls under gravity, and traction slide block prolongs guide rail and does uniformly accelrated rectilinear motion, and electric spark clock prints displacement point on paper tape.
The beneficial effects of the utility model are: under the restriction of I-shaped guide rail, slide block can be made strictly by rectilinear motion, slide block upset can be effectively prevented simultaneously, and roller structure can effectively reduce the frictional force of slide block and guide rail, the frictional resistance change impact on slide block acceleration can be reduced further, additionally this uniformly accelrated rectilinear motion laboratory table can be positioned on any desktop, applied widely.
On the basis of technique scheme, this utility model can also do following improvement.
Further, described upper end, bottom bottom surface on be fixedly connected with sucker, the opening of described sucker deviates from the bottom surface of upper end, bottom, and described sucker can make uniformly accelrated rectilinear motion laboratory table fix on the table better, it is prevented that laboratory table is slided or drops from desktop.
Further; the faying face of described bottom and guide rail is fixedly connected with one end of spring; the other end of described spring is the free end of corresponding slide block; the axis of described spring is parallel with the direction of motion of slide block; described spring can play the effect making slide block slow down; anti-limited slip block directly impinges faying face, causes slide block and faying face impaired, and this laboratory table can better be protected by described spring.

Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature being described, example is served only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in the figure, uniformly accelrated rectilinear motion laboratory table described in the utility model, including guide rail 1, upper end 101, bottom 102, slide block 2, electric spark clock 3, weight 4 and pulley 5, described guide rail 1 cross section is I-shaped, described guide rail 1 two ends have been respectively fixedly connected with upper end 101 and bottom 102, the bottom surface of upper end 101 and bottom 102 is positioned in same level, described upper end 101 end face is fixing connects electric spark clock 3, described bottom 102 end face is provided with support 103, described support 103 is fixedly connected with pulley 5, the open slot 202 in the through slide block 2 rear and front end face corresponding with guide rail 1 it is provided with bottom described slide block 2, two sides have been respectively fixedly connected with in described open slot 202 two rollers 201, described roller 201 is tangent with the top and bottom of guide rail 1 side I-shaped groove, what described slide block 2 was slidably connected is fixed on guide rail 1, described slide block 2 is towards sidewall fixing connection flexible cord 7 one end of bottom 102, described slide block 2 fixes connecting paper band 8 towards the sidewall of upper end 101, described flexible cord 7 other end connects weight 4 after walking around pulley 5, described paper tape 8 other end traverse electric spark clock 3, described flexible cord 7 is partly parallel to slide block 2 movement locus between pulley 5 and slide block 2, described paper tape 8 is partly parallel to slide block 2 movement locus between slide block 2 and electric spark clock 3, upper end 101, bottom 102 can limit slide block and skid off from guide rail 1, described upper end 101, the bottom surface of bottom 102 has been fixedly connected with sucker 9, sucker 9 opening deviates from upper end 101, the bottom surface of bottom 102, the faying face of described bottom 102 and guide rail 1 is fixedly connected with spring 6 one end, described spring 6 other end is the free end of corresponding slide block 2, described spring 6 axis is parallel with slide block 2 direction of motion.
