Abstract
The utility model discloses a light-shielding board which comprises a bottom frame, two supporting rods symmetrically and vertically arranged at two sides of the bottom frame and a shielding board installed between the two supporting rods. The inner sides of the two supporting rods are respectively provided with a guide rail groove, and the outer sides of the two supporting rods are respectively provided with a plurality of pin holes penetrating through the supporting rods. The shielding board penetrates through the pin holes through pins and fixed on the two supporting rods, wherein the height of the shielding board is adjustable. The light-shielding board is simple in structure, what is needed is to put the light-shielding board before a window near a blackboard and to properly adjust the height of the shield board, light reflection phenomena on the blackboard can be avoided, meanwhile lighting in other places cannot be influenced, the practice that lamps are turned on in class is needless, and electricity is saved.
Description
Technical field
The utility model relates to a kind of baffle plate that keeps the sun off, especially a kind of shadow shield be used to avoiding blackboard reflective light.
Background technology
Upper class hour in the classroom, we usually can find blackboard reflective light, and the word on blackboard does not just see Chu, run into such situation, and we often take to draw the curtain together, and turn on the method for electric light, and turn on light daytime, the waste electricity consumption.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of shadow shield be used to avoiding blackboard reflective light.
In order to solve the problems of the technologies described above, the utility model comprises that underframe, symmetry are vertically set on two support bars of underframe both sides and are arranged on two shutters between described support bar.
Two described support bar inboards all are formed with a guide-track groove, and the outside all is formed with the pin hole that runs through inside and outside a plurality of, and described shutter passes by pin that pin hole and two described support bars are fixed together and be highly adjustable.
The utility model is simple in structure, before only need placing it in the window that closes on blackboard, suitably adjusts the shutter height, can avoid occurring on blackboard reflective phenomenon, also can not affect other local daylightings simultaneously, attends class therefore need not turn on light, and has saved electricity consumption.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model shadow shield.
The specific embodiment
Referring to Fig. 1, shadow shield of the present utility model comprises that underframe 1, symmetry are vertically set on two support bars 2 of underframe 1 both sides and are arranged on two shutters 3 between described support bar 2.
Two described support bar 2 inboards all are formed with a guide-track groove 4, and the outside all is formed with the pin hole 5 that runs through inside and outside a plurality of, and described shutter 3 passes by pin 6 that pin hole 5 and two described support bars 2 are fixed together and be highly adjustable.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but within these embodiment are included in scope of the present utility model.
