Description
Technical field
The utility model relates to a kind of experimental demonstration device, especially a kind of spring Deformation Experiments apparatus for demonstrating.
Background technology
Probe into the lecture experiment of elastic force and spring elongates relation, be incorporated in the multiple teaching material of existing use as lecture experiment very important in high school physics, existing experimental demonstration device is generally a support vertically installed, the upper end of described support has mounted ruler and extension spring respectively, the lower end of this extension spring is shaped with arrow, experiment mounts multiple counterweight successively in the bottom of described extension spring when carrying out, and after mounting counterweight by record afterwards, the lower pan position of described arrow demonstrates out the experimental result of elastic force and spring elongates relation qualitatively.
In existing experimental demonstration device spring and ruler and bracket end adopt the mounting means that mounts only a side end be connected, the end side of described spring and ruler is unsettled, therefore cannot ensure that the axis of spring parallels with the elongated end of ruler, and then cannot ensure that in the arrow that lower spring end is made and ruler, institute's scale making is perpendicular, thus cause the error of experimental result; And because spring is the mounting means mounted, be in extended state because gravity spring is inevasible, time when extended state overlong time or excessively, spring then cannot bounce back, and loses efficacy and becomes inelastic deformation, and caused the mistake of experimental result.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of level to install, and experimental result is accurate, can a kind of spring Deformation Experiments apparatus for demonstrating of qualitative examination elastic force and spring elongates relation.
The utility model is achieved through the following technical solutions:
A kind of spring Deformation Experiments apparatus for demonstrating, it is characterized in that: comprise front fixed block and rear fixed block, be fixed with one between described front fixed block and rear fixed block and evenly make graduated dip stick, the front fixed block being positioned at this dip stick side is provided with a side end of an extension spring, the axis of this extension spring parallels with described dip stick direction of measurement, the end side of described extension spring is arranged on one and is shaped with in the brace of pointer, the opposite side of this brace is provided with one for mounting the lanyard of counterweight, the end of described lanyard by the made groove of the fixed pulley installed outside rear fixed block to downward-extension.
And upper surface and the rear fixing upper surface of described front fixed block are located in the same horizontal plane, and are fixed with described dip stick between this front fixed block upper surface and rear fixed block upper surface, are provided with a reinforcement behind described front fixed block lower end between fixed block lower end.
And, described pointed and dip stick position perpendicular.
And, outside the axis of described extension spring and described rear fixed block set pulley inner groovy minimum point be located in the same horizontal plane.
And described lanyard end is shaped with one for mounting the link of counterweight, and this lanyard adopts stiff lightweight material.
Advantage of the present utility model and good effect are:
In the utility model, front fixed block upper surface and rear fixed block upper surface are located in the same horizontal plane, the dip stick be fixedly mounted with between front fixed block and rear fixed block coordinates reinforcement, can by front fixed block, rear fixed block and dip stick 4 are fixed, thus ensure that extension spring axis parallels with dip stick direction of measurement, outside the axis of extension spring and rear fixed block set pulley inner groovy minimum point be located in the same horizontal plane and can ensure, in brace pointed and dip stick direction of measurement perpendicular, thus make experimental measurements more accurate; Lanyard adopt stiff light material to ensure extension spring is in compact state when not mounting counterweight, guarantee that in experiment, extension spring is in elastically-deformable state, thus can calculate elastic force and spring elongates relation qualitatively.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 side view.
Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of spring Deformation Experiments apparatus for demonstrating, the utility model innovation is, comprise front fixed block 1 and rear fixed block 5, upper surface and the rear fixing upper surface of this front fixed block are located in the same horizontal plane, be fixed with by bolt 9 dip stick 10 that is evenly shaped with scale 11 respectively between described front fixed block upper surface and rear fixed block upper surface, the front fixed block being positioned at this dip stick side is provided with a side end of an extension spring 2, the axis of this extension spring parallels with described dip stick direction of measurement, the end side of described extension spring is arranged on one and is shaped with in the brace 3 of pointer 12, the opposite side of this brace is provided with one for mounting the lanyard 4 of counterweight, the end of described lanyard by outside rear fixed block by the made groove of the hard-wired fixed pulley of pulley yoke 67 to downward-extension.
For ensureing that extension spring axis parallels with dip stick direction of measurement, outside the axis of described extension spring and described rear fixed block set pulley inner groovy minimum point be located in the same horizontal plane, described pointed and dip stick position perpendicular, between described front fixed block lower end and rear fixed block lower end, a reinforcement 14 is installed.
Extension spring is in compact state, and keep elastic deformation, described lanyard adopts stiff lightweight material.
For the ease of testing, described lanyard end is shaped with one for mounting the link 13 of counterweight.
Use procedure of the present utility model is:
When the utility model uses, first the end that lanyard relaxes is placed in the groove that fixed pulley outside surface makes by experimenter, make its end unsettled to downward-extension, experimenter can mount counterweight successively in link afterwards, and one by one record mount quantity not wait counterweight time, the reading of institute's scale making in pointer and dip stick, because the quality of counterweight is determined, after mounting counterweight, the gravity of counterweight and the pulling force of spring are one group of reacting force, size is identical, thus coordinate the tensile elongation of extension spring to get final product the quantitative relation calculating elastic force and spring elongates, complete experimental demonstration, reach experiment purpose.
In the utility model, front fixed block upper surface and rear fixed block upper surface are located in the same horizontal plane, the dip stick be fixedly mounted with between front fixed block and rear fixed block coordinates reinforcement, can by front fixed block, rear fixed block and dip stick 4 are fixed, thus ensure that extension spring axis parallels with dip stick direction of measurement, outside the axis of extension spring and rear fixed block set pulley inner groovy minimum point be located in the same horizontal plane and can ensure, in brace pointed and dip stick direction of measurement perpendicular, thus make experimental measurements more accurate; Lanyard adopt stiff light material to ensure extension spring is in compact state when not mounting counterweight, guarantee that in experiment, extension spring is in elastically-deformable state, thus can calculate elastic force and spring elongates relation qualitatively.
