Abstract
The utility model relates to an anti-reflection blackboard; and a blackboard (1) is provided with an adjusting mechanism which is installed on the wall and can be used for adjusting the angle of the blackboard by swinging or moving the blackboard (1) towards front and back as well as left and right. The blackboard can be adjusted at different angles and moved within a certain range, so that characters and the like which are written on the blackboard can be clearly recognized at different positions. The anti-reflection blackboard has simple structure and is convenient to install and use.
Description
Technical field
The utility model relates to the culture and education articles for writing, is a kind of reflection prevention blackboard that can both know the identification font in different orientation specifically.
Background technology
The wall hanging blackboard that uses all is to be fixedly mounted on the position now, wants to adjust relatively difficulty of position, and the angle of blackboard is uncontrollable in use.Can there be reflective phenomenon in diverse location and angle or see because of the problem at visual angle.Such as, in school, the two groups of former row students that keep to the side look at the blackboard reflective phenomenon are just arranged, and cause font smudgy, can influence these a few row students' study and cause phenomenon such as stravismus.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, adjusts angle and easily mobile, all can know the reflection prevention blackboard of identification font at diverse location.
The reflection prevention blackboard that the utility model provides, this blackboard has the governor motion that can be installed on the wall, and described governor motion comprises the telescopic member of the position, left, center, right that is installed in the blackboard back side.
Described governor motion also can comprise telescopic member and opposite side and the hinged pole of blackboard that is installed in a blackboard middle part and a side.
Described governor motion also can comprise the telescopic member that is installed in the left and right sides, the blackboard back side and be hinged on the pole of blackboard back side medium position.
Described telescopic member is flexible folding rule or extension sleeve.
The beneficial effects of the utility model are:
Thereby this blackboard owing to have can be installed on the wall and can by swing adjust the blackboard angle or with blackboard forwards, backwards about equal governor motions movably, like this by adjusting angle and mobile blackboard within the specific limits, can guarantee all can avoid not seeing, can both know font that identification is write on the blackboard etc. because of reflective at diverse location.The utility model is simple in structure, easy to install, is worth applying in places such as schools, helps improving student's school grade and reduces phenomenon such as stravismus.
Description of drawings
Fig. 1 is first kind of structural representation of the present utility model;
Fig. 2 is second kind of structural representation of the present utility model;
Fig. 3 is the third structural representation of the present utility model.
With reference to Fig. 1, the reflection prevention blackboard that the utility model provides, thereby this blackboard 1 have can be installed on the wall and can by swing adjust blackboard angle or with blackboard 1 forwards, backwards about equal governor motions movably. Described governor motion comprises the telescopic member 2 of the position, left, center, right that is installed in blackboard 1 back side. Like this, but blackboard about 1 all swing and two side shiftings to the left and right change angle and the position of blackboard 1.
The specific embodiment
With reference to Fig. 2, be that with Fig. 1 difference described angle adjusting mechanism comprises the pole 3 that the telescopic member 2 that is installed in blackboard 1 middle part and right side and left side and blackboard 1 are hinged, but the right swing changes the angle of blackboard 1.Conversely, the position of the telescopic member 2 on pole 3 and right side is interchangeable, but left side swing changes the angle of blackboard 1 like this.
With reference to Fig. 3, be that with Fig. 2 difference described angle adjusting mechanism comprises the telescopic member 2 that is installed in the left and right sides, blackboard 1 back side and is hinged on the pole 3 of blackboard back side medium position, but like this blackboard left side and the right all swing change the angle of blackboard 1.
During installation,, telescopic member 2, pole 3 are left wall respectively free end is fixed on the wall then can as Fig. 2.
What show among above-mentioned telescopic member 2 figure is flexible folding rule, and the structure that in like manner also available extension sleeve and other can reach same effect replaces.
Claims (6)
