Auxiliary equipment with adjustable use duration of point-reading machine system for children education

Abstract

The invention relates to the technical field of children education eye protection, and discloses an auxiliary equipment with adjustable use duration of a point-reading machine system for children education, which comprises a sleeve frame, a control box is fixedly connected to the bottom end in the sleeve frame, a movable rod is movably inserted in the left part in the control box, and a counting gear is movably inserted in the middle in the control box. The right end of the counting gear is engaged with a transmission gear, and the right end of the transmission gear is engaged with a boss wheel. An electronic screen is inserted into the middle of the interior of a sleeve frame, the lower end of the sleeve frame makes contact with a gasket at the upper end of a supporting plate, a driving wheel is rotated, the driving wheel drives a tooth-shaped pressing plate to move rightwards along a sleeve block to clamp the lower position of the left end of the electronic screen, meanwhile, the tooth-shaped pressing plate drives a sliding block to move rightwards through a linkage rod, and the sliding block drives a clamping plate to move rightwards; and the upper position of the left end of the electronic screen is fixed, so that the electronic screen can be automatically fixed in the protective sleeve when a child uses the point-reading machine, and the point-reading machine is prevented from being broken during use.

Description

technical field [0001] The invention relates to the technical field of eye protection for children's education, in particular to an auxiliary device with adjustable use time of a point reader system for children's education. Background technique [0002] With the continuous improvement of our country's education level, today's education methods are gradually tending to be networked, and more and more electronic devices are being put into education. Among them, children's educational equipment should be more worthy of attention, especially for some Children in preschool education, because children's eyes are relatively tender, when using electronic products, the use time of children must be strictly controlled to prevent myopia caused by watching electronic products for a long time.
