Abstract
An adjustable rostrum used for Chinese teachers comprises a T-shaped rostrum body, wherein the lower end of the rostrum body is connected with a lifting table, the lifting table is provided with a slide way, and the bottom end of the rostrum body is connected with the slide way. Sliding holes are formed in the left portion of the side wall of the rostrum body and the right portion of the side wall of the rostrum body respectively. A transverse rod handle is connected in the sliding holes. The two ends of the transverse rod handle are connected with control plates respectively. Triangular protrusions are arranged on the upper portions and the middle portions of the control plates. The lower ends of the control plates are connected with control plate springs. Control plate spring grooves are formed outside the control plate springs and connected with the bottom of the lifting table. The adjustable rostrum can be used for the Chinese teachers.

above-mentioned object realizes by following technical scheme:
a kind of Chinese teacher uses adjustable dais, and its composition comprises: dais, and described dais is T shape, and the lower end at described dais connects lifting platform, and described lifting platform has slideway, and the bottom at described dais connects described slideway.
described lifting platform has and draws hole at left part, the right part of sidewall, in described stroke hole, connect cross bar handle, the two ends of described cross bar handle are laterally deeply drawn hole and are connected with longitudinal control panel, cross bar handle is mutually vertical with control panel, the top of described control panel and middle part all have triangular hill, the lower end of described control panel connects control panel spring, and the outside of described control panel spring has control panel spring groove, and control panel spring groove connects lifting platform bottom.
described lifting platform has cavity, the inwall bilateral symmetry of described cavity has fixture block groove, in described fixture block groove, connect fixture block spring, described fixture block spring connects fixture block, the front end of described fixture block has triangle plush copper, described fixture block longitudinally has the rectangular opening matching with control panel, connects described control panel in described rectangular opening.
the inner side of described cavity connects chute wall, and described chute wall has slideway cinclides, described slideway cinclides and described fixture block horizontal alignment, and fixture block stretches out in slideway cinclides.
the middle part of described chute wall both sides connects U-shaped control panel limit collar, and described control panel limit collar has control plate hole, and described control panel is slidably connected in described control plate hole.
beneficial effect:
1. the utlity model has lifting platform, make dais can raise and decline handled easily.
the utility model can be by user's free adjustment height, and can not decline after raising, and the teacher of different heights all can be used.
lifting platform of the present utility model has fixture block, makes dais be lifted rear ejection, and blocks dais, and it can not be declined.
fixture block of the present utility model has rectangular opening, connects control panel in rectangular opening, makes the ejection of fixture block have limiting distance, can not drop.
accompanying drawing explanation:
accompanying drawing 1 is the internal structure schematic diagram of this product.
accompanying drawing 2 is front views of accompanying drawing 1.
the specific embodiment:
embodiment 1:
a kind of Chinese teacher uses adjustable dais, and its composition comprises: dais 1, and described dais is T shape, and the lower end at described dais connects lifting platform 2, and described lifting platform has slideway 3, and the bottom at described dais connects described slideway.This structure can make dais realize lifting by the slideway in lifting platform by pressing down cross bar handle.
embodiment 2:
chinese teacher described in embodiment 1 uses adjustable dais, described lifting platform 2 has and draws hole 4 at left part, the right part of sidewall, in described stroke hole, connect cross bar handle 5, the two ends of described cross bar handle 5 are laterally deeply drawn hole and are connected with longitudinal control panel 6, cross bar handle 5 is mutually vertical with control panel 6, top and the middle part of described control panel 6 all have triangular hill 7, the lower end of described control panel 6 connects control panel spring 8, and the outside of described control panel spring has control panel spring groove 9.Control panel spring groove connects lifting platform bottom.In this structure, cross bar handle 5 is mutually vertical with control panel 6, cross bar handle exposes lifting platform, in the time controlling, in the Hua hole, two ends of cross bar handle, slide, in the time that control panel is motionless, because the elastic force of the control panel spring of control panel bottom makes control panel and cross bar handle all in the top.
embodiment 3:
chinese teacher described in embodiment 2 uses adjustable dais, described lifting platform has cavity 10, the inwall bilateral symmetry of described cavity 10 has fixture block groove 11, the described interior connection fixture block of fixture block groove 11 spring 12, described fixture block spring connects fixture block 13, the front end of described fixture block has triangle plush copper 14, and described fixture block longitudinally has the rectangular opening 15 matching with control panel 6, connects described control panel 6 in described rectangular opening.This structure is in the time that control panel is motionless, and fixture block arrives in slideway because the elastic force of fixture block spring stretches out cavity by slideway cinclides, blocks the bottom at dais; In the time pressing sheer pole handle, because control panel has projection, projection is deep in the rectangular opening of fixture block and makes fixture block to the motion of fixture block spring place, and fixture block is by being retracted in slideway in cavity, and the bottom at dais loses the support of fixture block, and dais declines.
embodiment 4:
chinese teacher described in embodiment 3 uses adjustable dais, the inner side of described cavity connects chute wall 16, described chute wall 16 has slideway cinclides 17, described slideway cinclides and described fixture block horizontal alignment, fixture block stretches out in slideway cinclides, what this structure made that fixture block can level stretches out in slideway cinclides, retracts.
embodiment 5:
chinese teacher described in embodiment 2 or 4 uses adjustable dais, the middle part of described chute wall 16 both sides connects U-shaped control panel limit collar 18, described control panel limit collar has the plate hole 19 of control, described control panel 6 is slidably connected in described control plate hole, this structure can prevent when by sheer pole handle 5 that cross bar handle and control panel from dislocation or displacement occurring, make vertical the moving of control panel in control plate hole, and the projection of control panel can be blocked in the lower end of control panel limit collar, prevent that control panel from, because elastic force excessively raises, making position moderate.
the two ends of described cross bar handle are laterally deeply drawn hole and are connected with longitudinal control panel, cross bar handle is mutually vertical with control panel, its composition comprises: dais, described dais is T shape, the lower end at described dais connects lifting platform, described lifting platform has slideway, and the bottom at described dais connects described slideway.
described lifting platform has and draws hole at left part, the right part of sidewall, in described stroke hole, connect cross bar handle, the two ends of described cross bar handle all connect control panel, the top of described control panel and middle part all have triangular hill, the lower end of described control panel connects control panel spring, the outside of described control panel spring has control panel spring groove, and control panel spring groove connects lifting platform bottom.
