Abstract
The utility model relates to the technical field of electronic whiteboards, in particular to a projector trolley for an electronic whiteboard system. The projector trolley for the electronic whiteboard system comprises a base with universal wheels, wherein stand columns are arranged on the base, not less than three sets of clamping positions are arranged on the front face of each stand column, and not less than three screw holes are formed in the side face of each stand column. The projector trolley for the electronic whiteboard system further comprises a projection seat and fixing screws. The projection seat comprises a seat plate and fixing pieces fixedly connected with the seat plate, wherein each fixing piece is provided with a clamping piece and a fixing hole, the clamping pieces are matched with the clamping positions respectively, fixing holes correspond to the screw holes respectively, and the fixing screws penetrate through the fixing holes respectively and are then connected with the screw holes respectively in a screwed mode. On one hand, the trolley can be conveniently pushed through the universal wheels of the base of the trolley, on the other hand, the projection seat can be selectively hung at and connected to the clamping positions at different heights on the stand columns, meanwhile, the projection seat is connected with the stand columns at different heights through the fixing screws of the side faces, therefore, the projection seat can be fixed at different heights, and the requirement for enabling a projector to rise and fall within a large range is met.
Description
Technical field
The utility model relates to the electronic whiteboard technical field, particularly electric whiteboard system projector go-cart.
Background technology
In electric whiteboard system, projector is main parts, projector claims again projector, is a kind ofly image or video to be projected to the equipment on curtain, can be connected with computing machine, VCD, DVD, BD, game machine, DV etc. by different interfaces and play corresponding vision signal.Projector is widely used in family, office, school and public place of entertainment, according to the mode of operation difference, CRT is arranged, LCD, and DLP etc. are dissimilar.In electric whiteboard system, projector is mainly used for visual information projection to electronic whiteboard.
In electric whiteboard system, more and more electronic whiteboards are generally to adopt portable electronic whiteboard, but projector remains and adopts furred ceiling to fix or be positioned on ordinary desktop, this just causes the mobile space of portable electronic whiteboard limited, simultaneously, in existing projector fixed sturcture, projector heave amplitude limited, and projector mount only has lift adjustment by a small margin as another, therefore the alerting ability of existing electronic whiteboard is caused to the certain influence.
Therefore, for solving weak point of the prior art, provide a kind of and can move flexibly and the electric whiteboard system of significantly lifting seems particularly necessary with the projector go-cart.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of can move flexibly and the electric whiteboard system projector go-cart of significantly lifting.
The purpose of this utility model is achieved through the following technical solutions:
Electric whiteboard system projector go-cart is provided, comprise the base that is provided with cardan wheel, be provided with column on described base, the front of described column is provided with the screens that is no less than three groups, the side opening of described column is provided with the screw that is no less than three, also comprise projection seat and fix screw, described projection seat comprises seat board and the connecting element be fixedly connected with described seat board, described connecting element is provided with and the fastener of described screens coupling and the fixed orifice corresponding with described screw, and described fix screw is spirally connected with described screw through after described fixed orifice.
Wherein, be provided with two hole clippings in described every group of screens, described every group of fastener includes two grabs corresponding with described hole clipping.
Wherein, described column comprises left column and right column, and the screens on described left column and right column and screw be corresponding and contour setting one by one respectively.
Wherein, described screens spaced set, described screw spaced set, the spacing between described screens equates with the spacing between described screw.
Wherein, be provided with guardrail on described seat board.
The beneficial effects of the utility model: the utility model provides electric whiteboard system projector go-cart, this go-cart comprises the base that is provided with cardan wheel, be provided with column on described base, described column front is provided with and is no less than three groups of screens, described column side offers the screw that is no less than three, also comprise projection seat and this fix screw, described projection seat comprises seat board and the connecting element be fixedly connected with described seat board, described connecting element is provided with and the fastener of described screens coupling and the fixed orifice corresponding with described screw, described fix screw is spirally connected with described screw through after described fixed orifice.On the one hand, cardan wheel by the go-cart base can promote this go-cart easily, on the other hand, the projection seat can select the screens of differing heights on column to be articulated, fix screw by side is connected the projection seat with the column height simultaneously, thereby realize that the projection seat can be fixed on differing heights, meets the significantly lifting demand of projector.
The accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model electric whiteboard system with the embodiment of projector go-cart.
Fig. 2 is the structural representation of the utility model electric whiteboard system with another visual angle of embodiment of projector go-cart.
In Fig. 1 and Fig. 2, include:
1---base, 11---cardan wheel, 2---column, 21---hole clipping, 22---screw, 3---projection seat, 31---seat board, 32---connecting element, 33---grab, 34---fixed orifice, 4---fix screw, 5---guardrail.
The specific embodiment
With the following Examples the utility model is further described.
The specific embodiment of projector go-cart for the utility model electric whiteboard system, as depicted in figs. 1 and 2, comprise: the base 1 that is provided with cardan wheel 11, be provided with column 2 on described base 1, described column 2 fronts are provided with and are no less than three groups of screens, described column 2 side openings are provided with the screw 22 that is no less than three, also comprise projection seat 3 and fix screw 4, described projection seat 3 comprises seat board 31 and the connecting element 32 be fixedly connected with described seat board 31, described connecting element 32 is provided with and the fastener of described screens coupling and the fixed orifice 34 corresponding with described screw 22, described fix screw 4 is spirally connected with described screw 22 through described fixed orifice 34 is rear.
