Abstract
A kind of three-dimensional book showing cam mechanism, comprise strip of paper used for sealing, common plane page and three-dimensional page, three clamping plate before, during and after three-dimensional page comprises, front plate is transparent material, cam and push rod are installed between front plate and middle clamp plate, between rear plate and middle clamp plate, drive gear set are installed.Rotational driving gear, drives and rotates with cam, and then drives push rod to slide.This three-dimensional book, can by the hands-on of student, learn cam motion intuitively, while this knowledge point of study, is put into practice simultaneously and consolidate this knowledge point.
Description
Technical field
The utility model relates to a kind of books, particularly a kind of three-dimensional book showing cam mechanism.
Background technology
Book is the carrier of knowledge, is that Students ' Learning is requisite.For the student of mechanical major, at this kind of subject based on schematic diagram of study mechanical principle, often feel gruelling, indigestion, because some concrete structures are all the printings of simple picture and text, student often needs to go to understand according to the imagination of oneself, and this is for mechanism uncommon in some daily lifes, and in understanding, difficulty is just very large.Teacher is when upper this kind of course, and simple explanation often can not be dealt with problems, and class can be made on the contrary to become uninteresting.Common way puts some ppt PowerPoints to assist understanding, but be confined to unidirectional seeing and listen, and the participation of student is low, enthusiasm is poor, explanation weak effect.
Summary of the invention
In order to there is shortcoming large by the understanding difficulty of printing figure message, that teaching is directly perceived not, students' participation degree is low when solving and learn now mechanical principle, a kind of three-dimensional book showing cam mechanism is provided, this three-dimensional book is convenient for carrying, manually actuated cam mechanism, demonstration and results of learning good.
For achieving the above object, the utility model is by the following technical solutions:
Show a three-dimensional book for cam mechanism, comprise strip of paper used for sealing, common plane page and three-dimensional page, common plane page, three-dimensional page are provided with binding hole, and common plane page, three-dimensional page and strip of paper used for sealing, through binding hole, are fixed by set collar; Three clamping plate before, during and after three-dimensional page comprises, front plate is transparent material, its cam and push rod are arranged between front plate and middle clamp plate, push rod coordinates with the external slide rail be fixed on middle clamp plate, and push rod is provided with projection, and this projection is given prominence between middle clamp plate and rear plate, the chute that projection is offered in middle clamp plate coordinates, middle clamp plate is fixed with elastic rubber band, and this elastic rubber band one end is fixed on middle clamp plate, and the other end is fixedly connected with projection; Between rear plate and middle clamp plate, be provided with drive gear set, first driven wheel in outside exposes outside clamping plate, and the second driven wheel and first, the 3rd driven wheel engage, and the 3rd driven wheel and cam coaxial are installed; Before, during and after cushion block is installed between clamping plate, pad thickness is greater than gear, cam mechanism.
Rotate the first driven wheel, drive and rotate with the coaxial mounted cam of the 3rd driven wheel of drive gear set, and then drive push rod to slide along external slide rail, elastic rubber band plays the effect of reset push rod.
This three-dimensional book, can by the hands-on of student, learn cam motion intuitively, while this knowledge point of study, is put into practice simultaneously and consolidate this knowledge point.
Accompanying drawing explanation
Fig. 1 is the utility model entirety structural representation.
Fig. 2 is the Facad structure schematic diagram of the utility model cam mechanism.
Fig. 3 is the structural representation of the utility model drive gear set.
Fig. 4 is the structural representation of clamping plate.
Fig. 5 is the side-looking structural representation of clamping plate.
Be labeled as in figure: 1 common plane page, 2 set collars, 21 binding holes, 3 three-dimensional pages, 4 cushion blocks, 5 chutes, 6 push rods, 61 external slide rails, the projection that the 62 push rod back sides coordinate with chute, 71 first driven wheels, 72 second driven wheels, 73 the 3rd driven wheels, 8 cams, 9 tension rubber bands.101 front plates, 102 middle clamp plates, 103 rear plates.
Embodiment
Embodiment one
Show a three-dimensional book for cam mechanism, comprise strip of paper used for sealing, common plane page and three-dimensional page, common plane page 1, three-dimensional page 3 are provided with binding hole, and common plane page, three-dimensional page and strip of paper used for sealing, through binding hole 21, are fixed by set collar 2; Three clamping plate 101,102,103 before, during and after three-dimensional page comprises, front plate 101 is transparent material, its cam 8 and push rod 6 are arranged between front plate 101 and middle clamp plate 102, push rod 6 coordinates with the external slide rail 61 be fixed on middle clamp plate, push rod is provided with projection 62, this projection is given prominence between middle clamp plate and rear plate, the chute 5 that projection 62 and middle clamp plate are offered coordinates, middle clamp plate is fixed with elastic rubber band 9, this elastic rubber band one end is fixed on middle clamp plate, and the other end is fixedly connected with projection; Between rear plate and middle clamp plate, be provided with drive gear set, first driven wheel 71 in outside exposes outside clamping plate, and the second driven wheel 72 and first, the 3rd driven wheel 73 engage, and the 3rd driven wheel 73 is coaxially installed with cam 8; Before, during and after cushion block 4 is installed between clamping plate, pad thickness is greater than gear, cam mechanism, makes gear, cam mechanism can be freely movable between clamping plate.
Open three-dimensional page, rotate the first driven wheel, band moving cam rotates, and push rod is slided between external slide rail along the track of cam, and tension rubber band produces tensile force enables push rod reset.
