Abstract

The utility model discloses a full-view blackboard belonging to the technical field of teaching aids. The full-view blackboard comprises blackboard bodies, a supporting frame, vertical movement guide rails, horizontal movement guide rails, guide wheel frames, a torsional pendulum mechanism and a counterweight system, wherein the supporting frame is fixedly connected with the vertical movement guide rails; a group of roller wheels on the guide wheel frame is arranged in the vertical movement guide rails, and the other group of roller wheels on the guide wheel frame is arranged in the horizontal movement guide rails; the torsional pendulum mechanism is mounted on the horizontal movement guide rails; the blackboard bodies are mounted on the torsional pendulum mechanism; the counterweight system is connected with the guide wheel frames. According to the full-view blackboard, the blackboard bodies can be mounted on the left and right sides of the supporting frame, are respectively of an independent structure and can be independently operated. In the design, the roller wheels and a pulley are adopted, so that the labor-saving operation is realized; by virtue of two layers of roller wheel structures of the guide wheel frames, three layers of frameworks such as the vertical guide rails, the horizontal guide rails and the guide wheel frames are superposed into a whole, so that the blackboard can freely slide in the vertical and horizontal directions; by virtue of connection of hinges on a swinging arm, three-degree-of-freedom movement can be realized. The full-view blackboard is applicable to various classrooms, and contributes to vision protection of students.

Description

Panorama blackboard

Technical field

The utility model belongs to a kind of technical field of teaching aid, specifically a kind of new design of blackboard.

Background technology

Normal blackboard is exactly one flat plate; The blackboard that also has a kind of lyceum to use, upper and lower two boards, can pull up and down, switch, the motion of this blackboard is that the side of blackboard has slider roller and slideway to match with housing.

But this blackboard can not move left and right, can not corner.In classroom, exist blackboard sometimes reflective, or to situations such as student visual angle discomforts, need to carry out fine tune to blackboard, above-mentioned blackboard just can not meet this requirement.

Summary of the invention

The purpose of this utility model is a kind of panorama blackboard of design, realizes upper and lower, left and right and twist motion, and adapt teaching needs.

The technical solution of the utility model is, a kind of panorama blackboard comprises blackboard, bracing frame, moves up and down guide rail, moves left and right guide rail, directive wheel frame, swinging unit, Weighting system.

Bracing frame with move up and down guide rail and be fixedly connected with, one group of roller on directive wheel frame is arranged on and moves up and down in guide rail, another group roller of directive wheel frame is arranged on and moves left and right in guide rail, move left and right swinging unit is installed on guide rail, blackboard is installed on swinging unit, and Weighting system connects directive wheel frame.

Directive wheel frame has four edges frame, at least two rollers are installed on every frame, the roller of installing on corresponding frame is in same plane, roller on directive wheel frame forms two planes, roller in a plane rolls moving up and down in guide rail, and the roller in another plane rolls moving left and right in guide rail.

Move left and right Guide Rail Design rectangular frame, framework is provided with guide rail;

Swinging unit, is provided with hinge axis at the two ends of swing arm, and branch's connection moves left and right guide rail and blackboard.

Weighting system, includes balancing weight, pull rope and assembly pulley, and assembly pulley is fixedly mounted on bracing frame, and pull rope one end connects balancing weight, walks around assembly pulley, and the other end connects directive wheel frame.

The weight of balancing weight, with directive wheel frame, move left and right guide rail, swinging unit and blackboard sum weight identical.Pull rope two ends weight is identical, in the time that blackboard moves up and down, can stop everywhere.

Above-mentioned panorama blackboard, can be on a bracing frame, and two blackboards are installed in left and right, and the structure of every blackboard and manipulation are separate.

The utility model has used roller and pulley in design, use operation brisk laborsaving, with the two-layer roller structure of directive wheel frame, make upper and lower and left and right rail and three layers of framework superimposed becoming one of directive wheel frame, realizing upper and lower and left and right is free to slide, add the chain connection in swing arm, can realize the motion of three degree of freedom.This blackboard, is suitable for multiple classroom and uses, and facilitates student, vision protection.

What panorama blackboard adopted is pure mechanical system, utilizes artificial application of force manual operation can complete whole actions completely.Therefore, the cost of making, installing and keep in repair is also lower, and simultaneous adaptation ability is the same with traditional blackboard, does not need other power such as electric power.Compare can be generally mobile blackboard, it has added oscillating function by a small margin, blackboard is used more flexible, in addition, blackboard moves slideway and oscillation system all in blackboard back, takes up room little, does not affect blackboard outward appearance.In addition, blackboard is upper and lower, left and right and swing all can independent operatings, between them without any constraint.Can realize according to blackboard size design different length track the motion of different amplitudes.
