Description
Technical field
The utility model relates to the teaching equipment field, specifically a kind of frame of the projector for computer teaching.
Background technology
In the computer teaching process, projector is one of the most frequently used teaching aid, is generally used for demonstration computer operating process etc.At teaching condition, preferably in multi-media classroom, projector all is preloaded in ceiling usually.And, for interim teaching or common classroom, projector can only be placed on desk or on ordinary stent usually, when needs move or need adjusting height of projector, very inconvenient, be unfavorable for carrying out smoothly of teaching.In the long-term use procedure of projector, directly contact support or desktop simultaneously, can't well dispel the heat, cause the long-term overheated work of projector, affect serviceable life.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, and a kind of reasonable in design, frame of the projector for computer teaching that result of use is good is provided.
The utility model solves the technical scheme that its technical matters adopts:
A kind of frame of the projector for computer teaching, comprise and place plate and pillar, pillar is telescopic prop, be provided with back up pad hinged with its lower surface middle part above pillar, the front portion of support plate upper surface is hinged with placement plate lower surface front portion, the support plate upper surface rear portion is connected by cambered way with placing between plate lower surface rear portion, described placement plate takes the shape of the letter U, be provided with the clamping hurdle on the placement plate, the rear and front end on clamping hurdle matches to merge with the rear and front end of placing plate respectively and is slidably connected with it; Be provided with exhaust fan at the middle part of placing plate.
A kind of frame of the projector for computer teaching, be provided with protection post and be fixedly connected with its upper end on its clamping hurdle, clearance fit between protection post and placement plate upper surface.
Compared with prior art, the beneficial effect produced is the utility model:
The utlity model has the characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, be used in interim teaching or place projector while in common classroom, carrying out computer teaching; The exhaust fan of bottom can effectively increase the radiating effect of projector, prevents that projector is because of long-time overheated work reduction of service life; Can be placed on the applicable position in classroom according to actual conditions, have advantages of that height control is convenient, it is stable to place, auxiliary heat dissipation is effective and easy to carry.
