Abstract

The utility model discloses a movable overturned blackboard, which comprises a blackboard surface and a support, wherein the blackboard surface can be connected on the support in an overturned mode. A fixing device for fixing the blackboard surface is arranged on the support. In the fixing device, a through hole is arranged on a cross beam, a spring type fixed buckle is arranged in the through hole, and the bottom end of the fixed buckle is provided with a U-shaped groove. When the fixed buckle is pressed down, the U-shaped groove of the fixed buckle supports the frame of the blackboard surface. The movable overturned blackboard has the beneficial effects that the two ends of the backboard and the support are connected by adopting big-head handles through a backboard supporting frame, the backboard supporting frame plays a balanced fixed role for the backboard, and the overturning is flexible; the overturned blackboard is fixed by adopting the spring type fixed buckle, so the use is flexible and convenient, and the appearance is novel; and the overturned blackboard adopts oblate steel pipes and does not have edges and corners, so children are not easily damaged when the overturned blackboard collides with children in the use process.

Description

A kind of removable turnover blackboard

Technical field

The utility model relates to a kind of teaching blackboard, particularly a kind of Dual-side blackboard of removable, flexible overturning.

Background technology

The portable blackboard of existing teaching usefulness is usually by blackboard panel and be configured to, and support adopts square tube to make, and has corner angle on the square tube, and particularly bumping with children in the childhood teaching use in teaching damages easily.And existing blackboard is all inconvenient in upset with fixedly the time.

Summary of the invention

At the shortcoming that existing teaching exists with portable blackboard, the utility model provides a kind of novel removable turnover blackboard.

To achieve these goals, technical solution adopted in the utility model is:

A kind of removable turnover blackboard, comprise blackboard panel, support, be connected with blackboard panel on the support, described support is provided with one and makes the fixing fixture of blackboard panel turningly, and described fixture is that crossbeam is provided with a through hole, be provided with a spring clip in the through hole, the clip bottom is provided with U-lag, and when clip was pressed, the U-lag of clip withstood the frame of blackboard panel, flexible and convenient to use, the outward appearance novelty.

Be connected by the major part handle between the frame two ends of blackboard panel and the support, blackboard is played the balance fixation, and flexible overturning.

Described support is that the cross section is circular or oval steel pipe (just oblate steel pipe), and it is compared with square tube, and oblate pipe does not have corner angle; In use bump and be not easy to damage with children;

Described blackboard panel is the double-sided two-purpose structure: one side is the green plate that can write with chalk; Another side is to write blank with the blank pen.

Described steel pipe specification is 30*60*1.2mm.

The beneficial effects of the utility model: the blackboard two ends are connected with support adopts the major part handle to connect by the blackboard bracing frame, and blackboard is played the balance fixation, and flexible overturning; The fixing spring clip that adopts of turnover blackboard, flexible and convenient to use, the outward appearance novelty; Adopt oblate steel pipe not have corner angle, in use bumping with children is difficult for damaging.
