Abstract
The utility model discloses a novel blackboard, which comprises a middle axle with an adjustable height and a plurality of blackboards which are hinged to the middle axle, wherein the middle axle is connected onto the pedestal in a rotating way, the angle of the blackboard can be adjusted, the overall angle of the blackboard can be further adjusted via rotating the middle axle, a gear lever is hinged to the middle axle between the two blackboards, and when people writes on the blackboard, the blackboard can be prevented from backwards moving due to stress according to the gear lever. The blackboard can be used on two sides, the use area of the blackboard is enlarged, the structure of the blackboard is simple, and the blackboard is convenient and clean to use.
Description
Technical field
The utility model relates to a kind of new type blackboard.
Background technology
Existing blackboard generally all is to be fixed on the body of wall, height and angle are all non-adjustable, and the usable floor area of blackboard is limited, can not keep after writing full writing, when carrying out new teaching, original writing need to be wiped, need former also again writing on the blackboard when meaningful of study next time, not only increase workload to teacher, nor make things convenient for Students ' Learning.
Summary of the invention
The technical problems to be solved in the utility model is for defects, and a kind of angle and new type blackboard highly adjustable, that increase the blackboard usable floor area are provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of new type blackboard with following structure, its design feature is to comprise adjustable for height axis and a plurality of blackboards that are hinged on the axis, and described axis is rotatably connected on the base, is hinged with lever on the described axis.
Described axis comprises major axis and minor axis, the bottom interval of described major axis is provided with a plurality of installing holes, described minor axis is rotatably connected in the base, is provided with the cavity that can insert for major axis in the described minor axis, described minor axis be provided with can for bolt by and through hole that major axis and minor axis are connected as one.
Described lever is hinged on the major axis between per two blackboards.
Adopt the new type blackboard of such scheme compared with prior art to have the following advantages: blackboard is hinged on the axis, can regulate the angle of blackboard, axis is rotatably connected on the base, therefore also can regulate the whole angle of blackboard by rotating middle shaft, be hinged with lever on the axis between two blackboards, lever can prevent that blackboard from moving after stressed when blackboard is write, blackboard can use on the two sides in the utility model, can increase the usable floor area of blackboard, and the utility model is simple in structure, health easy to use.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this new type blackboard comprises adjustable for height axis 1 and a plurality of blackboards 2 that are hinged on the axis 1, and blackboard 2 rings are located on the axis 1, and each blackboard 2 in the utility model can use on the two sides, increases the blackboard usable floor area.The upper and lower of axis 1 is connected with a plurality of in twos corresponding free bearings 5, and each blackboard 2 is provided with the fraising corresponding with free bearing 5, hinge is passed fraising blackboard 2 and axis 1 are articulated as one.Be hinged with a plurality of levers 4 on the described axis 1, lever 4 is hinged on the major axis 11 between per two blackboards 2, be to be hinged with lever 4 on the major axis 11 between the adjacent blackboard 2, hand has a thrust to blackboard 2 when blackboard 2 is write, may make blackboard 2 mobile backward, turn to major axis 11 vertical angle with lever 4 this moment, can stop the movement of blackboard 2.Axis 1 is rotatably connected on the base 3, axis 1 comprises major axis 11 and minor axis 12, the bottom interval of described major axis 11 is provided with a plurality of installing holes 13, described minor axis 12 is rotatably connected in the base 3, base 3 is provided with the cavity that can place minor axis 12, the diameter of described cavity is greater than the diameter of minor axis 12, make to leave the space that can rotate for minor axis 12 in the cavity of base 3, so axis 1 can drive blackboard 2 unitary rotation.Be provided with the cavity that can insert for major axis 11 in the minor axis 12, described minor axis 12 be provided with can for bolt by and through hole 14 that major axis 11 and minor axis 12 are connected as one.
During use, according to the installing hole 13 on the height requirement selection major axis 11, make it corresponding with the two through hole 14 on the minor axis 12, bolt is passed installing hole 13 and two through hole 14, by locking nut major axis 11 and minor axis 12 are connected to one, because blackboard 2 is hinged relationship with axis 1, therefore when blackboard 2 was write, blackboard may be stressed mobile backward, at this moment turning lever 4, make it vertical with major axis 11, prevent from moving behind the blackboard 2; A plurality of blackboards 2 can be according to any adjusting angle of different demands, and the blackboard usable floor area increases, and can write more content, does not wipe so that written contents is worried, and makes things convenient for the student to take notes; Promote blackboard 2 minor axis 12 is rotated in base 3, so axis 1 also can drive a plurality of blackboard 2 unitary rotation, the front and back position of adjusting blackboard 2 makes things convenient for Students ' Learning.
