It is further described.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It needs to illustrate
, attached drawing is all made of very simplified form and using non-accurate ratio, only conveniently, lucidly to aid in illustrating originally
The purpose of utility model embodiment.The same or similar appended drawing reference represents the same or similar component in attached drawing.
A kind of Teaching of Computer Graphics device, as depicted in figs. 1 and 2, including bracket 1, positioned at 1 top of bracket
It puts to put away sports equipment and 2 and is wound in the projection screen 3 put and put away sports equipment on 2, the end of the projection screen 3 is provided with weighted lever 4, institute
It states to be horizontally disposed on bracket 1 and has fixed groove body 5, the longitudinal section of the fixed groove body 5 is the U-shaped of upward opening, the fixation
Groove body 5 be located at it is described put put away sports equipment 2 underface, when the projection screen 3 is put down, the weighted lever 4 can be sticked in described solid
Determine in groove body 5, the fixed mechanism for fixing 4 position of weighted lever is provided on the fixed groove body 5.
The first fixation hole 6 is offered through the weighted lever 4 on the weighted lever 4, the fixed mechanism includes fixed link 7
And the second fixation hole 8 matched with first fixation hole 6, when the fixation weighted lever 4, the fixed link 7 is simultaneously
Across first fixation hole 6 and second fixation hole 8.Second fixation hole 8 offers two on the fixed groove body 5
A, two second fixation holes 8 are symmetrically distributed in the two sides of the bracket 1.
One end of the fixed link 7 is hemispherical.It is solid greater than described second that the other end of the fixed link 7 is provided with section
Determine the operation portion 9 in 8 section of hole.Anti- spring removal 10 is additionally provided on the fixed groove body 5, the present embodiment is preferably common spring,
The both ends of the anti-spring removal 10 are connect with the fixed groove body 5 and the operation portion 9 respectively, when the fixation weighted lever 4, institute
It states anti-spring removal 10 and is in natural length, i.e., anti-spring removal 10 is in not by the length of external force at this time.It is set on the fixed groove body 5
It is equipped with the guide cylinder 11 of tubular, the axle center of the guide cylinder 11 is conllinear with the axle center of second fixation hole 8, the fixed link 7
Activity fits in the inner wall of the guide cylinder 11.
Be tiltedly installed with hound 12 on the bracket 1, the both ends of the hound 12 respectively with the fixed groove body 5 and
The bracket 1 connects.There are two the settings of hound 12, and two hounds 12 are symmetrically distributed in the two of the bracket 1
Side.
A kind of Teaching of Computer Graphics device provided by the utility model is that receipts are put in control first when being imparted knowledge to students
Bar 2 rotates and puts down projection screen 3, and after projection screen 3 is put down completely, weighted lever 4 can be engaged to solid just
In the opening for determining groove body 5, weighted lever 4 is fixed in fixed groove body 5 by fixed mechanism at this time；Even if projection screen 3 at this time
When passed by from side by wind or someone and generate air-flow, movable trend is passed to weighted lever by projection screen 3
4, weighted lever 4 passes to fixed groove body 5 again, since fixed groove body 5 is fixed on bracket 1, fixed groove body 5 and exacerbation
The position of bar 4 can be stable holding, so projection screen 3 will not generate shaking, the effect of projection is good, teaching can also be steady
Fixed progress.Wherein the mode that projection screen 3 is put down can be through electric control folding and unfolding conventional in the market, be also possible to
Similar to the hand pulling type folding and unfolding of curtain, the folding and unfolding mode of projection screen 3 is not the key protection point of the present embodiment, therefore is not gone to live in the household of one's in-laws on getting married
It states.
It is to take out fixed link 7 from the second fixation hole 8 first in fixed weighted lever 4, anti-spring removal 10 extends at this time,
Then weighted lever 4 is horizontally arranged in the opening of fixed groove body 5, the first fixation hole 6 is right against the second fixation hole 8, decontrols solid
Fixed pole 7, fixed link 7 sequentially pass through the second fixation hole 8 and the first fixation hole 6 under the action of the elastic contractile force of anti-spring removal 10,
Fixed link 7 simultaneously engages fixed groove body 5 and weighted lever 4 simultaneously, completes the fixation of weighted lever 4, simple and convenient；Wherein in reality
It when border operates fixed link 7, is carried out by operation portion 9, the cross-sectional area of operation portion 9 is greater than the cross section of fixed link 7
Product, the operation point of application for being is bigger, and it is more convenient to operate；And the end of fixed link 7 is hemispheric, so solid actually cutting through
Can be more convenient when determining groove body 5 and weighted lever 4, prevent fixed link 7 from contradicting onto weighted lever 4 or fixed groove body 5.
After the completion of fixation, anti-spring removal 10 can prevent fixed link 7 from fixed groove body 5 under the elastic acting force of its own
It falls off, improves stability maintenance.Guide cylinder 11 provides the impulse in a direction, so that fixed link 7 can only water
Flat activity does not need artificially to be aligned when across fixed groove body 5 and weighted lever 4, and implementation is strong.
Active force is conducted to fixed groove body 5 by after the effect of projection screen 3 by weighted lever 4, and fixed groove body 5 can pass through
With bracket 1 be directly connected to a little and active force is conducted to bracket 1 by two hounds 12, i.e. hound 12 reduces fixing groove
The burden of junction between body 5 and bracket 1, improves the connective stability of fixed groove body 5 and bracket 1, while also improving solid
Determine the positional stability of groove body 5.
It should be noted that each embodiment in this specification is described in a progressive manner, each embodiment emphasis is said
Bright is the difference from other embodiments, and the same or similar parts in each embodiment may refer to each other.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the scope of the utility model
Fixed, any change, the modification that the those of ordinary skill in the utility model field does according to the disclosure above content belong to right and want
Seek the protection scope of book.
