Abstract

The utility model discloses a liftable platform, which comprises a lifting plate, threaded sleeves, a driving gear shaft, a driven gear shaft, a motor, a speed reducer and a chain. Pedal seats are respectively disposed at four corners under the lifting plate and respectively provided with the threaded sleeves, the driving gear shaft is connected with the speed reducer, the speed reducer is connected with the motor, the driving gear shaft is connected with the driven gear shaft via the chain, inner threads are arranged on the inner surfaces of the threaded sleeves, outer threads are respectively arranged on the outer surface of one end of the driving gear shaft and the outer surface of one end of the driven gear shaft, the threaded sleeves are respectively connected with the driving gear shaft and the driven gear shaft via the threads in a one-to-one correspondence way, and one end of the driven gear shaft is connected with a bearing block. The liftable platform is reasonable in structural design, teachers use the liftable platform conveniently, the position of the liftable platform can be adjusted randomly according to the heights of the teachers and a blackboard, the teachers standing on the liftable platform write on the blackboard more comfortably, students are not affected during learning, and learning efficiency of the students is improved.

Description

The up-down dais

Technical field

The utility model relates to a kind of school furniture, relates in particular to a kind of up-down dais.

Background technology

The give a lesson blackboard of usefulness of teacher is the seat according to students in the school, is convenient to Most students and observes and be provided with and fixing, generally is motionless after fixing; And the height that students is write word when hoping also that teacher writes on blackboard a bit; And the teacher who gives a lesson is because height is different, short women teacher particularly, and the height of when on blackboard, writing, wanting to write is a bit; Do not write when holding arm high and writing and severally ache with regard to arm; Very hard, and highly still do not reach requirement, so how there to be an ability can regulate the height at dais at any time according to the teacher's that teaches the comfort level that height requires and teacher writes; The teacher that conveniently teaches writes, and improving on class, the adjustable dais of efficient just becomes current required.

The utility model content

The technical problem that the utility model solved is to provide a kind of up-down dais, requires freedom to go up and down stably according to the teacher that teaches, and it is more comfortable that the teacher that teaches is write on blackboard, has improved the learning efficiency of students.

The technical scheme of the technical problem that the utility model solved is: a kind of up-down dais; Comprise lifter plate, silk braid, driving gear shaft, driven gear shaft, motor, reductor and chain, four jiaos of places are provided with pedal base respectively below the lifter plate, and pedal base is respectively equipped with silk braid; Driving gear shaft is connected with reductor; Reductor is connected with motor, and driving gear shaft is connected with driven gear shaft through chain, and the silk braid inner surface is provided with internal thread; The outer surface of the outer surface of driving gear shaft one end and an end of driven gear shaft is respectively equipped with external screw thread, silk braid be threaded respectively one to one driving gear shaft and driven gear shaft.

As optimized technical scheme, said driven gear shaft one end is connected with bearing block.

Because a kind of up-down dais of having adopted technique scheme, lifter plate, pedal base, silk braid are connected to one, and silk braid and driving gear shaft and driven gear shaft are that screw thread screws; Driving gear shaft connects each driven gear shaft with chain, behind remote controller control electric motor starting, and the driving gear shaft rotation; Drive the driven gear shaft rotation through chain, the silk braid that screw thread is screwed rises or descends, thereby the relative altitude that stands in teach teacher and blackboard on the lifter plate is changed; Regulate according to suitable writing highly of oneself; Well change writing posture, thereby saved muscle power, guaranteed the speed of writing; Also ensure the learning time of students, improved learning efficiency.

Description of drawings

Fig. 1 is the structural representation at the utility model up-down dais;

Among the figure: 1. lifter plate, 2. motor, 3. reductor, 4. driving gear shaft, 5. driven gear shaft, 6. silk braid, 7. chain, 8 bearing blocks, 9. pedal base.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment, further set forth the utility model, should be understood that these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to 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 Figure 1, a kind of up-down dais comprises lifter plate 1, silk braid 6, driving gear shaft 4, driven gear shaft 5, motor 2, reductor 3 and chain 7; Four jiaos of places are provided with pedal base 9 respectively below the lifter plate 1, and pedal base 9 is respectively equipped with silk braid 6, and driving gear shaft 4 is connected with reductor 3; Reductor 3 is connected with motor 2; Driving gear shaft 4 is connected with driven gear shaft 5 through chain 7, and silk braid 6 inner surfaces are provided with internal thread, and the outer surface of the outer surface of driving gear shaft 4 one ends and an end of driven gear shaft 5 is respectively equipped with external screw thread; Silk braid 6 be threaded respectively one to one driving gear shaft 4 and driven gear shaft 5, driven gear shaft 5 one ends are connected with bearing block 8.

Teach teacher when using the up-down dais, and the people can stand on the lifter plate 1, also can be in other position beyond the lifter plate 1; Be rotated with remote controller control motor 2, thereby drive driving gear shaft 4 rotations, driving gear shaft 4 drives driven gear shaft 5 rotations through chain 7; Because of the external screw thread of gear shaft 4 and the internal thread of silk braid 5 screw; Thereby make silk braid 5 rise or descend,, thereby make lifter plate 1 realize rising or descending through the rotation of control motor because of silk braid 5, pedal base 9 and lifter plate 1 are one; Any like this teacher can be according to the height regulated at will of own height and blackboard, and is more comfortable when writing.

This utility model is reasonable in design, and the teacher that teaches is easy to use, and is more comfortable when writing according to height regulated at will position own and blackboard, do not influence the learning time of students again, improved the learning efficiency of students.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; 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 variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.

All are from the design of the utility model, and the structure conversion of having done without creative work all drops within the utility model protection domain.
