According to the multifunctional teacher's desk, the simultaneous motion of three storage areas can be realized; furthermore, the multifunctional teacher's desk is simple in structure and low in cost, and devices used for teaching can be classified and placed, therefore the teacher's desk is convenient to use during use, and is applicable to different classrooms.

Description

Multi-functional lectern
Technical field
This patent belongs to teaching aid field, relates in particular to a kind of multi-functional lectern.
Background technology
At present, in university, the lectern of the inside, a lot of classrooms is all that generally these article are all random being put on lectern in order to place chalk and teaching aid, and a lot of lectern do not have memory function, and these are all that teacher has brought a lot of inconveniences while using.The shortcoming existing for present common dais, the present invention has designed a kind of multi-functional lectern, this lectern melts lectern and memory function and one, teaching aid and plotting equipment are placed disaggregatedly, not only can facilitate teacher to take, and making whole desk more clean, teacher uses more convenient.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, patent of the present invention provides a kind of lectern, this lectern not only retains the function of original lectern, and teaching aid and drawing instrument etc. are stored, teacher's very convenient equipment such as access chalk, ruler and teaching aid at school time.
The technical solution adopted for the present invention to solve the technical problems is: multi-functional lectern is mainly divided into three storage areas, chalk and water tumbler storage area, plotting equipment storage area, the storage areas such as teaching aid and briefcase.Pull the upper left arm-tie of lectern, drive chalk holder to move upward, drive the cabinet door of teaching aid cabinet and plotting equipment cabinet to open by interlinked mechanism simultaneously.Upper class hour, teacher moves arm-tie to the leftmost side, now chalk holder moves on desktop, the cabinet Men Jun of teaching aid cabinet and plotting equipment cabinet opens, teacher takes out the plotting equipment that need to use from plotting equipment cabinet, then briefcase and clothes etc. are put in teaching aid cabinet cupboard, teaching aid cabinet is provided with interlayer, can be by teaching aid, briefcase, overcoat layering is placed, and chalk dust is fallen cupboard the inside for preventing teachers when, and teaching aid cabinet can be realized independent switch and not affect the interlock of integrated model; After class, teaching aid and plotting equipment are put in cupboard, promote arm-tie, arm-tie is got back to home position, and chalk holder is got back to desk inside, and the cabinet door of both sides cupboard is closed.
Compared with prior art, the invention has the beneficial effects as follows: can realize the interlock of three storage areas, the present invention is simple in structure, with low cost, the equipment of using of teaching can be placed disaggregatedly, has avoided teacher's inconvenience in use.

Detailed description of the invention
As Fig. 1, shown in 2, be the overall structure figure of multi-functional lectern, wherein multi-functional lectern mainly comprises bracing or strutting arrangement, transmission device and cabinet composition.Bracing or strutting arrangement is made up of desk 2 and desktop 8, plays a supporting role for entirety.Upper class hour teacher pulls arm-tie 1, arm-tie 1 is connected with connecting rod III20 by revolute pair III21, the guide rail that arm-tie 1 drives chalk holder 19 to overlap 18 both sides along chalk holder while moving moves upward, and in the time that arm-tie 1 moves to extreme position, corrects and move to the position flushing with desktop 8 on chalk holder 19.When moving, arm-tie 1 also drive the drive curved rod 22 being connected with it to move, curved rod 22 drives the right cabinet door 4 of teaching aid cabinet to move by indexing mechanism 23, the right cabinet door 4 of teaching aid cabinet is fixedly connected with tooth bar I24, when the right cabinet door 4 of teaching aid cabinet moves, tooth bar I24 and gear 25 on it engage, and the another side of gear 25 and tooth bar II28 are intermeshing.In the time that arm-tie 1 moves, by the intermeshing motion that realizes the left cabinet door 3 of teaching aid cabinet of gear 25 and tooth bar I24 and tooth bar II28.Before class teacher takes out the teaching aid in teaching aid cabinet 5, and overcoat and briefcase are put into 5 li of teaching aid cabinets; Fall in teaching aid cabinet 5 for fear of chalk dust, teacher can close teaching aid cabinet 5, can realize intermittent movement by the length video disc 32 promoting in indexing mechanism 23 around the rotation of rotating shaft 33, it does not affect the switch of realizing the left cabinet door 3 of teaching aid cabinet and the right cabinet door 4 of teaching aid cabinet in the situation of interlock.In the time that chalk holder 19 moves, by revolute pair II17 drivening rod II16 motion, the connecting rod II16 other end is connected with slide block 13, in order to ensure that motion is in a plane, restriction slide block 13 slides in gripper shoe 15, and slide block 13 is with carry-over bar III28 motion by connecting rod 12; Tooth bar III28 is fixed on the left cabinet door 10 of plotting equipment cabinet, and on the fixing right cabinet door 11 of plotting equipment cabinet of tooth bar IV31, the rotating shaft II30 of gear II29 is fixed on desk 2, and gear II29 is intermeshing with tooth bar III28 and tooth bar IV31 respectively.In the time that tooth bar III28 moves, be with carry-over bar IV31 motion by engagement, the right cabinet door 11 of plotting equipment cabinet is opened, and the time teacher who attends class can select equipment as required.Lower class hour, teacher puts back to plotting equipment in plotting equipment cabinet 6, take out briefcase and overcoat at teaching aid cabinet 5, teaching aid is put in teaching aid cabinet 5 cupboards, push back arm-tie 1, along with arm-tie 1 moves, chalk holder 19 devices are got back in the chalk holder cover 20 of desk 2 inside, and the cabinet door of teaching aid cabinet 5 and plotting equipment cabinet 6 the right and lefts is closed.This new function dais both can keep desktop clean can also realize teacher's apparatus and place disaggregatedly, has very large help for present teaching.
