Abstract
Piecemeal moving type blackboard belongs to education and instruction technical field, it is therefore intended that solve the problem that the classroom context of prior art existence is not easy to comparison explanation.Piecemeal moving type blackboard of the present utility model includes: base plate, and the upper and lower of base plate is respectively arranged with the chute of horizontal direction, and centre position is provided with the slide rail of horizontal direction；The blackboard being arranged side by side with n block, the upper and lower of any one piece of blackboard is provided with strip plate, strip plate and blackboard form T-shaped bar structure, T-shaped bar structure chute with the upper and lower of base plate respectively coordinates and slides, the width of strip plate is more than the thickness of blackboard more than the width of chute opening, the width of chute and the stand out of strip plate；1 piece of blackboard back fixation of remaining n has the slide rail on slide block, slide block and base plate to coordinate slip.This utility model is by T-shaped bar structure and the setting of sliding groove structure, it is achieved that blackboard, relative to the conversion of position, effectively solves the problem that classroom context can not compare explanation.
Description
Technical field
This utility model belongs to education and instruction technical field, is specifically related to a kind of piecemeal moving type blackboard.
Background technology
At classroom teaching, writing on the blackboard amount is big, it will usually occur compareing the formula above write or accompanying drawing is explained further
Situation, a width figure or formula need to recycle, if these need around the figure recycled or formula
With other thing, teacher often to stroll about at the two ends of blackboard during explanation, be unfavorable for giving lessons and say in classroom
Solve.
Blackboard of the prior art is generally integral structure or mobile drawing structure, and the blackboard of integral structure exists
Drawback is detrimental to the comparison explanation of classroom context；The blackboard of mobile drawing structure generally comprises two pieces, two pieces can more than
Descend or horizontally slip, in the confined space, increasing the area of blackboard, it is impossible to the problem solving classroom context comparison explanation.
Utility model content
The purpose of this utility model is to propose a kind of piecemeal moving type blackboard, before and after solving the classroom that prior art exists
The problem that content is not easy to comparison explanation.
For achieving the above object, piecemeal moving type blackboard of the present utility model includes:
Base plate, the upper and lower of described base plate is respectively arranged with the chute of horizontal direction, and centre position is provided with level
The slide rail in direction；
The blackboard being arranged side by side with n block, the upper and lower of any one piece of blackboard is provided with strip plate, described strip plate
Forming T-shaped bar structure with blackboard, described T-shaped bar structure chute with the upper and lower of base plate respectively coordinates and slides, described length
The width of batten is more than the thickness of blackboard more than the width of chute opening, the width of described chute and the stand out of described strip plate
Degree；Remaining n-1 block blackboard back fixation has the slide rail on slide block, described slide block and described base plate to coordinate slip.
The value of described n is more than or equal to 3.
Described slide block and described blackboard back are adhesively fixed or are fixed by screw.
The bottom of the blackboard coordinated by sliding groove structure with base plate is provided with handle.
M group lock-screw, described lock-screw and the length of blackboard bottom it is evenly arranged with on the chute of described base plate bottom
Batten is at grade.
The value of described m and the value of n are equal.
Often group lock-screw includes two.
The beneficial effects of the utility model are: the back of the body that piecemeal moving type blackboard of the present utility model is arranged side by side by polylith
It is overall that plate constitutes blackboard, is wherein coordinated by T-shaped bar structure and chute between any one blackboard and base plate, T-shaped bar structure
The width of strip plate more than the thickness of blackboard, makes the back of the body more than the width of chute opening, the width of chute and the stand out of strip plate
Plate can do movable with opposed bottom, make the blackboard coordinated by sliding groove structure with base plate can to adjust before and after opposed bottom,
Ensure that this blackboard is protruding relative to other blackboards so that it is can slide in other blackboard fronts, suitably adjust between other blackboards
Width, and base plate slides into relevant position opposed bottom again by the blackboard that sliding groove structure coordinates and presses backward, it is ensured that all
Blackboard is generally aligned in the same plane, it is achieved that blackboard is relative to the conversion of position, after conversion, and the lock-screw that locking is corresponding, it is achieved and the end
Spacing at fore-and-aft direction of the blackboard that plate is coordinated by sliding groove structure, effectively solves classroom context and can not compare asking of explanation
Topic.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
Seeing accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, piecemeal moving type blackboard of the present utility model includes:
Base plate 1, the upper and lower of described base plate 1 is respectively arranged with the chute 101 of horizontal direction, and centre position is provided with
The slide rail 102 of horizontal direction；
The blackboard 2 being arranged side by side with n block, the upper and lower of any one piece of blackboard 2 is provided with strip plate 201, described
Strip plate 201 and blackboard 2 form T-shaped bar structure, and described T-shaped bar structure chute 101 with the upper and lower of base plate 1 respectively is joined
Closing and slide, the width of described strip plate 201 is more than the width of chute 101 opening, the width of described chute 101 and described strip plate
The stand out of 201 is more than the thickness of blackboard 2；Remaining n-1 block blackboard 2 back fixation has a slide block 103, described slide block 103 and described
Slide rail 102 on base plate 1 coordinates slip.
The value of described n is more than or equal to 3.
