The described mainboard back side, be all provided with the second slide block of two longitudinal arrangements near described mainboard both side ends, described second slide block is connected with the second slide be fixed on wall.
Described screw pair is made up of nut and leading screw, and described nut is arranged on described mainboard back side center position; The external screw thread of described leading screw is connected with described nut inner thread, and described leading screw one end is connected with described motor by described worm type of reduction gearing, and the other end is flexibly connected on the bracket.
All chain connection is adopted between subplate described in described mainboard both sides and every block.
The utility model is owing to taking above technical scheme, it has the following advantages: 1, the utility model is made up of mainboard and the subplate that is arranged on mainboard both sides owing to adopting, be positioned at the mainboard back side and be provided with motor, worm type of reduction gearing and screw pair, motor drives screw pair action by worm type of reduction gearing, and then driving whole blackboard to move up and down, its structure is simple, achieves blackboard Height Adjustable, the teacher facilitating height different uses, and is conducive to teacher's writing on the blackboard.2, the utility model is flexibly connected owing to adopting hinge between mainboard with subplate, and be provided with at the back side of every block subplate and stop support bar arbitrarily, by hinge and the effect stopping arbitrarily support bar, the angle of two pieces of subplates and metope is made to be all adjustable-angle, reflective to avoid, make the classmate being sitting in classroom side can see the writing on the blackboard content in blackboard distally clearly.The utility model can extensively be applied in educational training field.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the rearview of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model provides a kind of reflection-proof and adjustable for height blackboard, and it comprises support 1, first guide rail 2, motor 3, worm type of reduction gearing 4, screw pair, mainboard 5, subplate 6, stops support bar 7 and the first slide block 8 arbitrarily.
Support 1 and the first guide rail 2 are all fixedly installed on wall, and be positioned at support 1 top and be provided with motor 3 and worm type of reduction gearing 4, motor 3 connects screw pair by worm type of reduction gearing 4, and screw pair is arranged on support 1.Mainboard 5 back side is connected with support 1 by screw pair, and mainboard 5 two ends are flexibly connected one piece of subplate 6 respectively.Be positioned at every block subplate 6 back side, what subplate 6 outboard end was provided with two longitudinal arrangements stops arbitrarily support bar 7, each support bar 7 end of stopping arbitrarily is provided with first slide block 8, stop arbitrarily support bar 7 to be slidably connected with the first guide rail 2 be fixed on wall by the first slide block 8, when mainboard 5 moves up and down, make two pieces of subplates 6 by the first slide block 8 along the first guide rail 2 along with mainboard 5 moves up and down.
In above-described embodiment, as shown in Figure 2, be positioned at mainboard 5 back side, the second slide block 9, second slide block 9 being all provided with two longitudinal arrangements near mainboard 5 both side ends is slidably connected with the second guide rail 10 be fixed on wall.
In the various embodiments described above, screw pair is made up of nut 11 and leading screw 12, and nut 11 is arranged on mainboard 5 back side center position; The external screw thread of leading screw 12 is connected with nut 11 internal thread, and leading screw 12 one end is connected with motor 3 by worm type of reduction gearing 4, and the other end is movably connected on support 1.Drive motor 3 makes leading screw 12 rotate, and now mainboard 5 moves up and down along leading screw 12 under the effect of screw pair, and drives the second slide block 9 to slide up and down along the second guide rail 10, thus realizes the object regulating blackboard height.After blackboard moves to object height, blackboard is made to be fixed on object height by the self-locking of worm type of reduction gearing 4.
In the various embodiments described above, between mainboard 5 both sides with every block subplate 6, hinge 13 is all adopted to be connected.
In sum, the utility model in use, can realize moving up and down of mainboard 5 by screw pair, drives the second slide block 9 to slide up and down along the second guide rail 10, mainboard 5 can be moved up and down stably; Meanwhile, drive two pieces of subplates 6 to move up and down by mainboard 5, the height realizing blackboard regulates.Hand steered any one piece of subplate 6, by hinge 13, stop the angle angle that support bar 7 can regulate this subplate 6 and metope arbitrarily, blackboard is avoided reflective, and stopping arbitrarily support bar 7 can make subplate 6 remain unchanged with the angle angle of metope, and when writing on subplate 6, this angle also can not change.
The various embodiments described above are only for illustration of the utility model; wherein the structure of each parts, connected mode and manufacture craft etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
