Description
Technical field
The utility model relates to physical and mechanical experiment field, is specifically related to the experimental provision of a kind of elastic force and spring elongates relation.
Background technology
In senior middle school's Experiments of Machanics, the elastic force of spring and the experiment of spring elongates magnitude relation particularly important.But at present, student must estimate the elongation of spring when testing, and this brings no small error to rigorous experiment itself, makes experimental result inaccurate.And when using hook code, general what adopt is the hook code of integer mass, experiment is made not have a ubiquity.
Utility model content
The utility model is in order to solve the problem, propose the experimental provision of a kind of rocker-type elastic force and spring elongates relation, this experimental provision is incident upon on the scale of rule by laser locator and makes reading more accurate, and automatically can show spring elongates current force value used, make test data more accurate.
To achieve these goals, the utility model adopts following technical scheme:
An experimental provision for rocker-type elastic force and spring elongates relation, comprises rule, bracing frame, pulling force sensor, spring, laser locator, screw mandrel, handwheel; Wherein, described rule is fixed on inside bracing frame, and scale increases from the bottom up successively; Support frame as described above is flat " U " shape support; The bottom of described pulling force sensor is connected with bracing frame, and upper end is connected with spring; Described spring one end is connected with pulling force sensor, and the other end is connected with laser locator; Described laser locator one end is connected with spring, and the other end is connected with screw mandrel; The lower end of described screw mandrel is connected with laser locator, and upper end is connected with handwheel, and passes the upper beam of bracing frame; Described handwheel is arranged on the top of screw mandrel.
An experimental provision for rocker-type elastic force and spring elongates relation, support frame as described above is formed by Plate Welding, two soffit plane and support bracket fastened top surface being parallel.
An experimental provision for rocker-type elastic force and spring elongates relation, described pulling force sensor, with a display screen, can show current force value.
An experimental provision for rocker-type elastic force and spring elongates relation, laser locator can launch " one " word ray, and projection on the scale.
Principle of work of the present utility model is:
Elected when determining measuring spring, spring one end is connected to the top of pulling force sensor, the spring other end is fixed on the bottom of laser locator, pulling force sensor is made zero, and the scale of record experiment front laser locator place rule, shake handwheel makes screw mandrel rise, the scale of laser locator and the current force value of pressure transducer after record rises.Continue shake handwheel, carry out organizing experiment more, test and completely draw matched curve by described point drawing.
The beneficial effects of the utility model are:
(1) the utility model structure is simple, easy to operate;
(2) the utility model can avoid the error that artificial reading brings;
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Wherein, 1 is rule, and 2 is bracing frame, 3 be pulling force sensor, 4 for spring, 5 be laser locator, and 6 be screw mandrel, 7 is handwheel.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, the experimental provision of a kind of rocker-type elastic force and spring elongates relation, comprises rule 1, bracing frame 2, pulling force sensor 3, spring 4, laser locator 5, screw mandrel 6, handwheel 7; Wherein, described rule 1 is fixed on inside bracing frame 2, and scale increases from the bottom up successively; Support frame as described above 2 is flat " U " shape support; The bottom of described pulling force sensor 3 is connected with bracing frame 2, and upper end is connected with spring 4; Described spring 4 one end is connected with pulling force sensor 3, and the other end is connected with laser locator 5; Described laser locator 5 one end is connected with spring 4, and the other end is connected with screw mandrel 6; The lower end of described screw mandrel 6 is connected with laser locator 5, and upper end is connected with handwheel 7, and passes the upper beam of bracing frame 2; Described handwheel 7 is arranged on the top of screw mandrel.
Elected when determining measuring spring 4, spring 4 one end is connected to the top of pulling force sensor 3, spring 4 other end is fixed on the bottom of laser locator 5, pulling force sensor 3 is made zero, and the scale of record experiment front laser locator 5 place rule 1, shake handwheel 7 makes screw mandrel 6 rise, the scale of laser locator 5 and the current force value of pressure transducer 3 after record rises.Continue shake handwheel 7, carry out organizing experiment more, test and completely draw matched curve by described point drawing.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
