At present, multimedia teaching is popularized in each colleges and universities of the whole nation, and projector and computing machine are just being brought into play more and more important effect as main multimedia teaching facility.Existing projector generally passes through box or hanger suspending in the below of classroom ceiling, and box and suspension bracket function singleness only play fixedly to put projector, the adjusting inconvenience at projector inclination angle; Simultaneously, projector is positioned at eminence, is in for a long time in the high temperature gas flow environment to work, and is prone to phenomenons such as deadlock, the less stable of projector work.
Computer installation is mainly containing dual mode in the classroom: a kind of is with whole naked being placed on the dais of main frame, display, mouse and keyboard, but each parts manageability not; Another kind is that main frame, display, mouse and keyboard all are placed in the iron chest that is similar to the dais, though be convenient to management, the cost at dais is higher, and a dais just needs about 3000 yuan, is unfavorable for promoting the use of.
Along with each colleges and universities going deep in multimedia teaching, many classrooms all need to be equipped with teaching equipments such as projector, computing machine.Because existing projector box or suspension bracket do not have anti-theft feature, when so at night the classroom being offered the student and studying by oneself in scheduled time, must specify the special messenger to guard projector and computing machine, with Antistealing; Perhaps in the classroom that is equipped with projector, computing machine antitheft door is installed, evening is not open to the student.The classroom resource of each colleges and universities is relatively limited, in case wherein a part of classroom is sealed, then the student goes up the classroom minimizing of self-study at night, is unfavorable for that the student learns.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of projector box of having things stolen of effectively preventing.
The technical solution of the utility model is as follows: a kind of projector box, comprise projector and casing, projector hangs in the casing, casing is made up of top cover, base plate, Qianmen, back door and two blocks of side plates, its key is: the upper surface at described casing top cover is installed infrabasal plate by bolt, bar in the central vertical of this infrabasal plate is fixing, cover loads cover of upholstery in the lower end of interior bar, this time cover of upholstery is gone into the infrabasal plate cover wherein, the upper end of interior bar is stretched in the outer bar of coaxial cable with it, and both are by long padlock connection; The fixing upper substrate in the top of bar outside described, fitting in the bottom surface of this upper substrate and ceiling, and fixes by expansion bolt, and the upper end of bar is overlapped and is loaded onto cover of upholstery described outside, and cover of upholstery is gone into the upper substrate cover wherein on this.
Adopt above technical scheme, projector hangs in the casing, locks on the casing, can prevent effectively that projector is stolen; The expansion bolt that bolt that the casing top cover is connected with infrabasal plate and upper substrate are connected with ceiling is respectively by cover of upholstery and last cover of upholstery cover are gone into down; the cover of upholstery locking protection; can play decoration, effect attractive in appearance; can avoid bolt to expose again, prevent from projector to be stolen together with casing by demounting bolt.Be connected by long padlock between interior bar and the outer bar, so that regulate the height of projector.
Above above-mentioned projector end face, gusset is installed by screw, the middle part of this gusset is connected with the casing top cover by hanging hinge, in the forward and backward both sides that hang hinge an adjusting screw(rod) is set respectively, the lower end of this adjusting screw(rod) is connected with gusset, casing top cover and infrabasal plate are passed in the upper end, are locked by wing nut.By turning the wing nut that hangs hinge front side or rear side, can regulate the inclination angle of projector, guarantee to be projected in the image quality on the wall curtain, not only convenient but also quick.
Place main frame in above-mentioned casing, this main frame is positioned at the below of projector, and is supported by described box bottom.The utility model is amplified on the basis of former box, and main frame is placed in the box, and the various connecting lines of main frame can be drawn from box, thereby has improved the integrated function of box, and helps centralized management.
Inside surface at above-mentioned back door is installed burglar alarm.When the back door is improper when opening, burglar alarm sounds the alarm, and has further strengthened anti-theft effect.
The minisize axial-flow blower fan all is installed on the biside plate of above-mentioned casing, and wherein the minisize axial-flow blower fan on side plate is an induced draft fan, and the minisize axial-flow blower fan on another piece side plate is a pressure fan.Under the effect of induced draft fan and pressure fan, the heat that projector and main frame work produce can in time be pulled away, and can effectively prevent to crash projector and main frame work stable secure.
Beneficial effect: the utility model had both made things convenient for the centralized management of multimedia equipment by projector and main frame are installed in the same box, can play good anti-theft effect again, and simultaneously, the stability of equipment work improves greatly.In addition, when guaranteeing anti-theft effect, multi-media classroom can offer the student and go up self-study at night, for the student provides abundant studying space.The utlity model has be skillfully constructed, simple in structure, implement easily, the low characteristics such as (850 yuan/platform) of cost, be suitable for large-scale promotion and use.
