Abstract

The utility model discloses a sliding type self-wiping blackboard consisting of a blackboard (1) and a blackboard eraser (2), which is characterized in that an upper rim and a lower rim of the blackboard (1) are respectively clamped in inner side chutes of an upper transverse H-shaped slide rail (3) and a lower transverse H-shaped slide rail (3'), the upper transverse H-shaped slide rail (3) and the lower transverse H-shaped slide rail (3') are as wide as a classroom; and the blackboard eraser (2) is vertical strip-shaped and is as long as the distance between the upper transverse H-shaped slide rail (3) and the lower transverse H-shaped slide rail (3'), a sleeve (10) at the back of the blackboard eraser (2) is sleeved on a sliding bar (11), and the upper end and the lower end of the sliding bar (11) are respectively provided an upper sliding hook (4) and a lower sliding hook (4') clamped in outer side chutes of the upper transverse H-shaped slide rail (3) and the lower transverse H-shaped slide rail (3'). As the blackboard eraser and the blackboard can wipe backwards and forwards, the sliding type self-wiping blackboard can regulate the visual angles of students on the blackboard, which is beneficial to protection on the eyes of the students and also convenient for short teachers and students to wipe the blackboard; in addition, the sliding type self-wiping blackboard has the advantages of simple structure, convenience in use, large wiping area, time saving and labor saving.

Description

Plug-type automatic erasing blackboard

Technical field

The utility model relates to the improvement of a kind of blackboard and blackboard eraser, belongs to the instructional technology field, and specifically a kind of blackboard and blackboard eraser all can push-and-pulls, realize the plug-type automatic erasing blackboard that erases the board by push-and-pull.

Background technology

In school instruction, present employed blackboard all is fixed on the wall, and employed blackboard eraser is movable, can only be that the people holds blackboard eraser and wipes back and forth when erasing the board, and realizes erasing the board.The deficiency of this blackboard is: because blackboard is to fix, can only look side ways so be sitting in the student of both sides, classroom, influence student's eyesight.And when erasing the board employed blackboard eraser, by length is not enough 20cm, wide for the plate body of not enough 10cm, bristle and shirt rim constitute, and the dense planting that bristle is in a row, one-tenth is listed as is fixed the shirt rim in the bottom surface of plate body in the bottom periphery of plate body, the shirt rim is enclosed in a week of bristle, and the shirt rim is done for the rubber leather.The deficiency of this blackboard eraser: the one, the dust under wiping is scattered, flies upward, and pollutes classroom environment, influences teachers and students' health; The 2nd, each area of wiping is little, needs repeatedly to wipe back and forth, wastes time and energy.At present, the blackboard eraser of the use band dust catcher that also has, the blackboard eraser of this band dust catcher, be that plate body is made box body, in box body, install dust-absorbing fan, on the diapire of plate body, be provided with and inhale the hole, during use, bristle is pressed on the blackboard, wipes moving back and forth, chalk mark dust is wiped down, and the dust under wiping sucks in the box body, the blackboard eraser of this band dust catcher, existing deficiency: the one, enough power supplys must be arranged, what have also will connect lead, not only wastes energy, and uses inconvenient; The 2nd, each area of wiping is still less, still needs repeatedly to wipe back and forth, uses both time-consuming, inconvenient again.In addition, more than all blackboard erasers, for the not high teachers and students of stature, the top chalk trace of blackboard often can't be wiped.

Summary of the invention

The purpose of this utility model is to provide a kind of not only blackboard eraser to wipe back and forth, and blackboard also can be wiped back and forth, and can regulate the blackboard visual angle, and simple in structure, time saving and energy saving, wipe breadth long-pending big, to the also convenient plug-type automatic erasing blackboard of using of teachers and students of short and small stature.

For reaching above purpose, the technical scheme that the utility model adopted is: this plug-type automatic erasing blackboard, comprise that blackboard and blackboard eraser constitute, it is characterized in that: the upper and lower frame of described blackboard is stuck in the inboard chute of upper and lower " worker " sub-shape slide rail, the length of upper and lower " worker " sub-shape slide rail is consistent with the width in classroom, thereby blackboard is slidably reciprocated to the both sides in classroom along upper and lower " worker " sub-shape slide rail, like this, can regulate the student's who is sitting in the both sides, classroom visual angle; Described blackboard eraser is vertical strip blackboard eraser, the length of blackboard eraser and last, distance between " worker " sub-shape slide rail is consistent down, make the both sides up and down that once to wipe when erasing the board to blackboard, fixing upper bush on the backboard face of blackboard eraser, sleeve set is on slide bar, on slide bar, the lower end is fixed with respectively, following Slip Hook, can be with slide bar and last, following Slip Hook is made as an integral body, on, following Slip Hook snaps in respectively, down in the chute in " worker " sub-shape slide rail outside, on, following Slip Hook slides along chute, drive blackboard eraser and do laterally to slide, to the chalk handwriting erasing on the blackboard along the plate face of blackboard; Sleeve can rotate along slide bar, by the rotation of sleeve, blackboard eraser is rotated.

The utility model is also implemented by following measure: the both sides at blackboard eraser are provided with turning cylinder, on turning cylinder, be provided with and sweep bristle, end at turning cylinder is provided with rubber tire, be provided with the arc scraper plate in the outside that sweeps bristle, when the relative blackboard of blackboard eraser slides, sweep bristle and sweep, thereby the dust under wiping is swept in the dust chamber of blackboard eraser both sides to the direction of blackboard eraser, dust falls into downside, pours out from downside.

The beneficial effects of the utility model are: this plug-type automatic erasing blackboard, not only blackboard eraser can be wiped back and forth, and blackboard also can be wiped back and forth, can pass through moving of blackboard, can regulate the visual angle of student, help the protection of student's eye, simultaneously blackboard, blackboard is moved relative to blackboard eraser, erase the board; And simple in structure, easy to use, wipe breadth long-pending big, time saving and energy saving, use teachers and students of short and small stature are also convenient.
