Abstract
The utility model discloses a line drawing device for teachers, comprising a fixing base. A sucker which is used to fix the fixing base on a blackboard is arranged at two ends of the fixing base, a sliding base is sheathed on the fixing base, a sliding device is arranged between the fixing base and the sliding base, a chalk fixing device is installed on the sliding base. In the utility model, the fixing base is fixed on the blackboard and a chalk is fixed on the sliding base by utilizing the sucker, line is drawn by means of the moving of the sliding base on the fixing base, line lattice which is needed by English teaching and Music teaching can be drawn conveniently. The structure is simple, the using is convenient, the drawing time of the line lattice can be shorten greatly, thereby class time is occupied as little as possible to draw the line lattice, the device is beneficial to improving the teaching efficiency and teaching process.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of line-plotting device that is applicable to that English or music lesson are used.
Background technology
In English or music teaching process, generally can use four line lattice or five line lattice, so that write use for the beginner demonstrates.But in teaching in the past, the teacher need be with the ruler every line that draws on blackboard, grasps collimation between them according to the sensation of oneself simultaneously.Four line lattice or five line lattice are more loaded down with trivial details when drawing, and the classroom drafting can take a large amount of instructional blocks of times, is unfavorable for improving teacher's classroom teaching efficiency, serious delay teaching process.
The utility model content
Technical problem to be solved in the utility model provides teacher a kind of easy to use, simple in structure and uses chalker.
For solving the problems of the technologies described above, the technical solution of the utility model is: the teacher uses chalker, comprise holder, described holder both ends are provided with described holder are fixed on sucker on the blackboard, be set with sliding seat on the described holder, be provided with carriage between described holder and the described sliding seat, on the described sliding seat chalk fixing device be installed.
As a kind of improvement, described carriage is arranged on the contact-making surface of described sliding seat and described holder, comprises semi-cylindrical canyon that is arranged on the described sliding seat and the chute that is arranged on the described holder between described depression and the described chute ball being installed.
As further improvement, described chalk fixing device comprises being arranged on and is used to insert the chalk installing hole that chalk is used on the described sliding seat.
As further improvement, described chalk installing hole is set to five.
Owing to adopted technique scheme, the teacher uses chalker, comprise holder, described holder both ends are provided with described holder are fixed on sucker on the blackboard, be set with sliding seat on the described holder, be provided with carriage between described holder and the described sliding seat, on the described sliding seat chalk fixing device be installed; The beneficial effects of the utility model are: utilize sucker that holder is fixed on the blackboard, chalk is fixed on the sliding seat, rely on sliding seat mobile on holder to carry out setting-out, needed line lattice easily in English teaching or the music teaching can draw, simple in structure, easy to use, can shorten the drafting time of line lattice greatly, thereby the least possible time in classroom that takies removes the Plotted line lattice, helps to improve efficiency of teaching and teaching process.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in drawings, the teacher uses chalker, comprises holder 1, and described holder 1 both ends are provided with described holder 1 is fixed on sucker 2 on the blackboard, and holder 1 utilizes sucker 2 with its firm being fixed on the blackboard, is convenient to finishing smoothly of setting-out; Be set with sliding seat 3 on the described holder 1, be provided with carriage between described holder 1 and the described sliding seat 3, described carriage is arranged on the contact-making surface of described sliding seat 3 and described holder 1, comprise semi-cylindrical canyon (not shown) that is arranged on the described sliding seat 1 and the chute 11 that is arranged on the described holder 1, between described depression and the described chute 11 the ball (not shown) is installed, smooth more when making promotion sliding seat 3 carry out setting-out, holder 1 is contacted with face between the sliding seat 3 become a contact, and ball rolls in chute 11 and advances during setting-out, thereby reduced the frictional force between holder 1 and the sliding seat 3, helped carrying out fast smoothly of setting-out.
On the described sliding seat 3 of present embodiment chalk fixing device is installed, described chalk fixing device comprises being arranged on and is used to insert the chalk installing hole 4 that chalk is used on the described sliding seat 3 that described chalk installing hole 4 is set to five.
When the four line lattice that the picture English letter is used, only need get final product with chalk is installed in four adjacent in chalk fixing device chalk installing holes; And when drawing staff, then need in whole chalk installing holes, install chalk, simple in structure, easy to use.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
All are from design of the present utility model, and the structure conversion of having done without creative work all drops within the protection domain of the present utility model.
