Abstract
The utility model discloses an anti -reflective height -adjustable blackboard, including blackboard body, back seat and guide rail, back seat fixed connection is at blackboard body's rear side, the both sides of back seat all are provided with the link, fixed mounting has the gear on the link, still be provided with the recess in the guide rail, the inside fixed mounting of recess has the rack, back seat and guide rail pass through the gear and rack toothing connects, there are first light screen and second light screen in blackboard body's both sides movable mounting respectively, fixed mounting is gone back to blackboard body's front side bottom has the rack. The utility model discloses can can shelter from the light of both sides effectively for the blackboard according to the angle of lightmap's different angular adjustment light screens, avoid producing anti - optical phenomena, through setting up the rack inside gear and the recess on the back seat, can realize that the blackboard reciprocates, make things convenient for different crowds' use more.
Description
Technical field
The utility model relates to teaching aid technical field, is specially a kind of reflection-proof and adjustable for height blackboard.
Background technology
Blackboard not refers in particular to the plate face of black, traditional sense is said it be one can the plane of repeated writing, plate face is hard, is used for teaching.Make with plank or ground glass etc., can to write above with specific writing materials such as chalks.Mostly be black, blackish green or white.
The wall hanging blackboard of present use is all be fixedly mounted on a position, and think adjustment location comparison difficulty, the angle of blackboard is uncontrollable in use.Can reflective phenomenon be there is and not see in diverse location and angle.In school, the two groups of former row students that keep to the side look at the blackboard and just have reflective phenomenon, cause font smudgy, can affect the study of this few row student and cause the phenomenons such as stravismus; Because existing blackboard is all be fixedly mounted on metope, the height of adjustment blackboard of having no idea, the people of different height uses and will feel very inconvenient, so we propose a kind of reflection-proof and adjustable for height blackboard.
Utility model content
The purpose of this utility model is to provide a kind of reflection-proof and adjustable for height blackboard, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of reflection-proof and adjustable for height blackboard, comprise blackboard body, back seat and guide rail, described back seat is fixedly connected on the rear side of blackboard body, the both sides of described back seat are provided with link, described link is installed with gear, also groove is provided with in described guide rail, the inside of described groove is installed with tooth bar, described back seat and guide rail are connected with a joggle by gear and tooth bar, the both sides of described blackboard body are movably installed with the first shadow shield and the second shadow shield respectively, also rack is installed with bottom the front side of described blackboard body.
Preferably, described link is welded on back seat both sides, and the quantity of described link is no less than two.
Preferably, described first shadow shield and the second shadow shield are all by the both sides of hinge in blackboard body, and the first shadow shield is identical with the specification of the second shadow shield.
Preferably, described rack welding in the inside of groove, and the width of described tooth bar and length respectively with the width of groove with highly identical.
Compared with prior art, the beneficial effects of the utility model are: this reflection-proof and adjustable for height blackboard, by being arranged on the first shadow shield and second shadow shield of blackboard body both sides, and due to shadow shield and blackboard be by together with hinge, the angle of the different angles adjustment shadow shield that can irradiate according to light, can effectively for blackboard blocks the light of both sides, avoid producing reflective phenomenon, by being arranged on the tooth bar of gear on back seat and inside grooves, blackboard can be realized move up and down, be more convenient for the use of different crowd.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial schematic diagram of the utility model height adjusting structure.
In figure: 1 blackboard body, 2 first shadow shields, 3 second shadow shields, 4 hinges, 5 back seats, 6 racks, 7 guide rails, 8 grooves, 9 links, 10 gears, 11 tooth bars.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of reflection-proof and adjustable for height blackboard, comprise blackboard body 1, back seat 5 and guide rail 7, back seat 5 is fixedly connected on the rear side of blackboard body 1, the both sides of back seat 5 are provided with link 9, link 9 is welded on back seat 5 both sides, and the quantity of link 9 is no less than two, link 9 is installed with gear 10, groove 8 is also provided with in guide rail 7, the inside of groove 8 is installed with tooth bar 11, tooth bar 11 is welded on the inside of groove 8, and the width of tooth bar 11 and length respectively with the width of groove 8 with highly identical, back seat 5 and guide rail 7 are connected with a joggle by gear 10 and tooth bar 11, moving up and down of blackboard can be realized, the both sides of blackboard body 1 are movably installed with the first shadow shield 2 and the second shadow shield 3 respectively, first shadow shield 2 and the second shadow shield 3 are all hinged on the both sides of blackboard body 1 by hinge 4, the angle of different angles to the first shadow shield 2 and the second shadow shield 3 can irradiated according to light during use regulates, effectively block the illumination of both sides, avoid occurring reflective phenomenon, and the first shadow shield 2 is identical with the specification of the second shadow shield 3, rack 6 is also installed with bottom the front side of blackboard body 1, rack 6 can be used for placing good blackboard eraser etc. respectively, chalk dust can also be accepted simultaneously, chalk dust is avoided directly to fall on the ground, be difficult to cleaning.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
