Abstract
The utility model belongs to the technical field of electronic education appliances, which relates to an automatic lifting electric education table for electric education appliances. The electric education table is an improvement of the existing education table. The education table adopts top door opening. The education table is provided with a screw-typed lifting mechanism for electric education appliances and a control system. Adopting the electric education table can avoid the complicated attachment and detachment of electric education appliances in the existing electronic education, and the safety performance is excellent. When in use, the electric education table has simple operation and stable lifting for electric education appliances, which is applicable to electric education.
Description
The utility model belongs to the audiovisual teaching equipment technical scope, relates to a kind of audio-visual education programme tool automatic lifting audio-visual education programme platform.
At present, the wooden table top religion table that generally adopts in the electronic teaching fails to design at the characteristics of electronic teaching, during teaching the installation of audio-visual education programme such as television set, projector tool and with after dismounting, keeping etc. relatively heavier, loaded down with trivial details, both be unfavorable for teaching, incompatible with modern sense, the civilization sense of electronic teaching again, and security personnel's performance is bad.
The purpose of this utility model is the characteristics at electronic teaching, designs a kind of electronic teaching that both had been beneficial to, and the audio-visual education programme tool automatic lifting audio-visual education programme platform of good security personnel's performance is arranged again.
This practicality new novel is improved on existing religion table basis, the religion table be a top door opening, is provided with screw audio-visual education programme tool elevating mechanism and control system thereof in the religion.
The said screw lifting mechanism of the utility model can be single screw lifting mechanism, twin-screw elevating mechanism or multiscrew elevating mechanism, the utility model adopts double-screw type, its structure is for respectively installing a screw rod on the forward and backward side of frame-type elevator platform, lifting nut is installed on the screw rod, article carrying platform is fixedly mounted on the lifting nut, sprocket wheel all is equipped with in the bottom of two screw rods, connect by chain between two sprocket wheels, wherein, initiatively the bottom of screw rod is equipped with the load gear, on load gear and the rack-mounted micro machine with gears engaged.In order to make the article carrying platform lifting steady, can on the left and right side of elevator platform, slide bar be installed, be set with slide block on the slide bar, slide block is fixedlyed connected with article carrying platform.The control system of the said twin-screw elevating mechanism of the utility model can be electric-control system, by A.C. contactor, fuse, ZC, FC relay, D micro machine, QC electric lock button, QA
