The difference of teacher's height is adjusted, and the volume of lectern is all bigger, cannot arbitrarily be moved, at school when front row classmate sight
It can be blocked by lectern, influence the study of student.
Utility model content：
The purpose of this utility model, which is solution, must not carry out height adjustment and the larger disadvantage of volume, provide a kind of Chinese
With foot-operated Liftable desk for teacher.
Above-mentioned purpose is realized by following technical scheme：
A kind of foot-operated Liftable desk for teacher of Chinese, composition include：Lower box, upper box, the interior peace of the lower box
Equipped with power plant, the power plant is connect with transmission device, and the power plant includes support plate, the support
Plate is mounted in the lower box, and the lower end of mobile bar passes through the circular hole of the support plate and drive link solid by mobile bar
Determine block connection, is cased with spring in the mobile bar, one end of the spring is fixedly connected with the support plate, described
The other end of spring is fixedly connected with the mobile bar, and the upper end of the mobile bar is fixedly connected with pedal, and described steps on
Plate is located in the bar-shaped trough of the lower box, and the both ends of the pedal are respectively provided with groove, the both ends of the bar-shaped trough
In the groove.
The foot-operated Liftable desk for teacher of the Chinese, the transmission device includes supporting rack, in the supporting rack
First transmission shaft is installed, the left end of first transmission shaft is equipped with turntable, and the turntable is logical with the drive link
The connection of turntable fixed block is crossed, the right end of first transmission shaft is equipped with first bevel gear, and the lower box is sleeved on four
Be fixedly connected with the pillar described in four on pillar, the pillar described in four be each passed through the circular hole of the upper box with it is upper solid
Fixed board is fixedly connected, and the lower end of the pillar described in four is fixedly connected with bottom plate respectively, second driving shaft respectively with it is described
Bottom plate connected by bearing with the lower box with the upper mounted plate, the second driving shaft with it is described
Upper box is threadedly coupled, and the lower end of the second driving shaft is equipped with second bevel gear, the first bevel gear with it is described
Second bevel gear be meshed, the lower end of the lower box is equipped with one group of idler wheel.
Advantageous effect：
1. the operation principle of the utility model is：Pedal is stepped on, pedal moves down, and drive link and mobile bar and turntable are all
For dynamic connection, mobile bar moves downwards through drive link and drives turntable rotation therewith, and the first transmission shaft rotates therewith, due to first
Bevel gear is meshed with second bevel gear, and second driving shaft rotation, second driving shaft is threadedly coupled with upper box, and upper box will
Realization moves up and down, and to realize the raising of height, when the spring-compressed on pedal is to maximum, unclamps pedal, pedal is in bullet
It is moved up under the action of spring, may then continue with and step on pedal downwards, realize continuous adjustment, it is desirable to can be when turning down height
When pedal is moved upwards up to half, pedal is stepped on downwards, and turntable can realize reverse rotation, to realize the reduction of height.
The utility model is matched using the first transmission shaft, second driving shaft, first bevel gear, second bevel gear structure,
So that height adjusting is more steady, in the case where pedal moves up and down, turntable is all rotated, in the process of adjusting
In the phenomenon that being not in pause.
One group of idler wheel is arranged in the lower end of the lower box of the utility model so that and lectern can be arbitrarily moved to anywhere,
Facilitate teachers.
The utility model is small, will not stop the sight of student.
The utility model uses the structure of lower box and upper box, and when without lectern, the height of lectern is preferably minimized, and is said
Desk body product narrows down to maximum, becomes two babinets, can be placed on any corner.
The left and right ends of the pedal of the utility model are fluted, and pedal can vertically be moved in the left side of lower box
It is dynamic.
Four of the utility model are fixed between pillar and lower box, can prevent the movement of fixed frame.
