Description
Technical field
The utility model relates to a kind of physical teaching aid, relates in particular to a kind of elastic force apparatus for demonstrating that is used for physics teaching, specifically is applicable to the distortion of demonstration spring and the relation between the elastic force.
Background technology
At present, during the professor that between the distortion of carrying out spring and elastic force, concerns in the physics teaching, owing to lack apparatus for demonstrating intuitively, can only carry out abstract specification by the teacher, teaching efficiency is relatively poor.
The Chinese patent Granted publication number is CN201181537Y; Granted publication day is that the utility model patent on January 14th, 2009 discloses a kind of physics teaching and uses the elastic force demonstrator; This elastic force demonstrator comprises: support, expelling plate, emission basket and spring, and support is connected support through hinge with expelling plate, and spring one end is connected with expelling plate; The other end is connected with support, and the emission basket is arranged on the end of expelling plate.Though this utility model can be known the distortion that shows spring and the relation between the elastic force, structure is fixed, and can only show a kind of distortion of spring, and the distortion that can not show multiple spring is with the relation between clearer explanation distortion and the elastic force, and adjustability is relatively poor.
Summary of the invention
The purpose of the utility model is to overcome relatively poor defective and the problem of adjustability that exists in the prior art, provides a kind of adjustability the stronger elastic force apparatus for demonstrating that is used for physics teaching.
For realizing above purpose; The technical solution of the utility model is: a kind of elastic force apparatus for demonstrating that is used for physics teaching, and this elastic force apparatus for demonstrating comprises entablature, sill and spring, an end of said spring is connected with an end of sill; The other end is connected with an end of entablature; The upside of the other end of entablature is provided with saddle, and the set inside of this saddle has the gravity ball, and between entablature, sill, is provided with vertical beam; The inside of said entablature, sill is respectively arranged with upper hopper chute and gliding groove, and the two ends up and down of vertical beam are slidingly matched with upper hopper chute, gliding groove respectively.
Said vertical beam comprises vertical beam and following vertical beam, and the upper end and the upper hopper chute of last vertical beam are slidingly matched, and the lower end is connected with following vertical beam, and the other end and the gliding groove of following vertical beam are slidingly matched, and upward vertical beam is a strip structure, vertical beam is a trapezoidal-structure down.
The set inside of said saddle has the deep-slotted chip breaker that matches with the gravity ball.
The diameter of said deep-slotted chip breaker is greater than the diameter of gravity ball.
Compared with prior art, the beneficial effect of the utility model is:
1, because a kind of elastic force apparatus for demonstrating that is used for physics teaching of the utility model is respectively arranged with upper hopper chute and gliding groove in the inside of entablature, sill; And the two ends up and down of vertical beam are slidingly matched with upper hopper chute, gliding groove respectively; During use, can adjust the corresponding arm of force of spring through the slip vertical beam, thereby make spring bear different pressure; So that produce different distortion, and then the relation between clearer explanation distortion and the elastic force.Therefore the adjustability of the utility model is stronger.
2, because a kind of set inside that is used for the elastic force apparatus for demonstrating saddle of physics teaching of the utility model has the deep-slotted chip breaker that matches with the gravity ball, during use, through the fixing gravity ball of deep-slotted chip breaker, fixed effect is better, is difficult for during use rocking and comes off.Therefore the fixed effect of the utility model is better.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: entablature 1, upper hopper chute 11, sill 2, gliding groove 21, spring 3, saddle 4, deep-slotted chip breaker 41, gravity ball 5, vertical beam 6, last vertical beam 61, following vertical beam 62.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is done further detailed explanation.
Referring to Fig. 1; A kind of elastic force apparatus for demonstrating that is used for physics teaching, this elastic force apparatus for demonstrating comprise entablature 1, sill 2 and spring 3, and an end of said spring 3 is connected with an end of sill 2; The other end is connected with an end of entablature 1; The upside of the other end of entablature 1 is provided with saddle 4, and the set inside of this saddle 4 has gravity ball 5, and between entablature 1, sill 2, is provided with vertical beam 6; One of special feature of the utility model is: the inside of said entablature 1, sill 2 is respectively arranged with upper hopper chute 11 and gliding groove 21, and the two ends up and down of vertical beam 6 are slidingly matched with upper hopper chute 11, gliding groove 21 respectively.The relation between clearer explanation distortion and the elastic force is convenient in this design.
Preferred vertical beam 6 comprises vertical beam 61 and following vertical beam 62; The upper end of last vertical beam 61 and upper hopper chute 11 are slidingly matched; The lower end is connected with following vertical beam 62, and the other end of following vertical beam 62 and gliding groove 21 are slidingly matched, and upward vertical beam 61 is a strip structure, vertical beam 62 is trapezoidal-structure down.This design is convenient to improve the stability of vertical beam 6.
The set inside of preferred saddle 4 has the deep-slotted chip breaker 41 that matches with gravity ball 5.The diameter of further preferred deep-slotted chip breaker 41 is greater than the diameter of gravity ball 5.This design is convenient to improve the fixed effect of gravity ball 5
During use; The pressure of gravity ball 5 passes to spring 3 through entablature 1, thereby makes it produce distortion with the relation between explanation distortion and the elastic force, and can be after producing a deformation; Adjust the spring 3 pairing arm of forces through slip vertical beam 6; Thereby make spring 3 bear different pressure, so that produce different distortion, and then the relation between clearer explanation distortion and the elastic force.
Therefore the utility model not only adjustability is stronger, and fixed effect is better.
