Description
Technical field
The utility model relates to a kind of mathematical education blackboard, belongs to realia technical field of structures.
Background technology
At present; mathematics teacher's upper class hour; frequent needs enumerate a large amount of formula on blackboard; due to these formula classrooms needing to use, therefore, if after erasing; also need to write on blackboard again; extremely bother, moreover teacher is when giving lessons; often can use certain formula; need to compare easy understand facing to formula and student explain, more time in classroom can be taken if write again when using, reduce efficiency of giving lessons; moreover; mathematics teacher attends class often to be needed to use ruler, needs now to look for during use, very inconvenient.
Summary of the invention
The purpose of this utility model is the weak point solving prior art existence, provides a kind of reasonable in design, does not take blackboard space, easy to use, improves the mathematical education blackboard of classroom efficiency.
The utility model is achieved through the following technical solutions:
A kind of mathematical education blackboard, its special character is to comprise two the vertical chutes 2 being installed on blackboard 1 left and right sides, vertical chute 2 comprises and to be fixedly connected with blackboard 1 plate face and the banded bottom land 3 that highly matches of length and blackboard 1, the left and right sides of bottom land 3 is equipped with the L-type rib 4 be structure as a whole with it, in two vertical chutes 2, the slide plate 5 that can slide up and down along chute 2 is all installed, the both sides of slide plate 5 are propped up by two L-type ribs 4, the centre of two slide plates 5 is all provided with the transverse arm 6 perpendicular with slide plate 5, two transverse arms 6 are all cylindrical and be hollow structure, in two transverse arms 6, ball 7 is installed, ball 7 is all fixed with connecting rod 8, two transverse arms 6 are equipped with for the strip opening through connecting rod 8, strip opening is through the whole length direction of transverse arm 6, between two connecting rods 8, strip is installed, for writing the subplate 9 of formula,
The length direction subscript of described subplate 9 is marked with graduation mark 15, can use as ruler;
In order to play position-limiting action, the sidewall of described rib 4 is provided with multiple jack separately, and the top of rib 4 is connected with lanyard 11, lanyard 11 be connected with jack with the use of latch 12;
The bottom of described subplate 9 is provided with multiple link 13 separately, link 13 is connected with clip 14.
A kind of mathematical education blackboard eraser of the present utility model, design ingenious, all formula all can be recorded on subplate before teachers' instruction, concrete using method is: drop-down subplate, then pusher subplate, subplate is made to be butted on rib, then all formula are all recorded on subplate by teacher, on lift subplate, on lift to correct position after, latch is inserted in jack, subplate can be fixed on current location, if teacher does not want to allow student see formula in advance, subplate can be pulled forward, subplate is driven can be moved forward and backward by ball, then be axle with connecting rod, rotate subplate, subplate is made to write the one side of formula towards blackboard, clip bottom subplate can clamp books or exhibiting pictures, subplate is provided with scale, can use as ruler, very easy to use.
Accompanying drawing explanation
Fig. 1: the structural representation of a kind of mathematical education blackboard of the utility model;
Fig. 2: the A of vertical chute is to structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
A kind of mathematical education blackboard of the present embodiment, comprise two the vertical chutes 2 being installed on blackboard 1 left and right sides, vertical chute 2 comprises and to be fixedly connected with blackboard 1 plate face and the banded bottom land 3 that highly matches of length and blackboard 1, the left and right sides of bottom land 3 is equipped with the L-type rib 4 be structure as a whole with it, in two vertical chutes 2, the slide plate 5 that can slide up and down along chute 2 is all installed, the both sides of slide plate 5 are propped up by two L-type ribs 4, the centre of two slide plates 5 is all provided with the transverse arm 6 perpendicular with slide plate 5, two transverse arms 6 are all cylindrical and be hollow structure, in two transverse arms 6, ball 7 is installed, ball 7 is all fixed with connecting rod 8, two transverse arms 6 are equipped with for the strip opening through connecting rod 8, strip opening is through the whole length direction of transverse arm 6, between two connecting rods 8, strip is installed, for writing the subplate 9 of formula, the length direction subscript of subplate 9 is marked with graduation mark 15, can use as ruler, in order to play position-limiting action, the sidewall of rib 4 is provided with multiple jack separately, and the top of rib 4 is connected with lanyard 11, lanyard 11 be connected with jack with the use of latch 12, the bottom of subplate 9 is provided with multiple link 13 separately, link 13 is connected with clip 14.
