Description
Technical field:
The utility model relates to realia, is specifically related to a kind of portable and collapsible blackboard.
Background technology:
At present, blackboard is widely used a kind of teaching tool in teaching.Blackboard is divided into two kinds, and one is fixed on the wall, for daily teaching; Another small blackboard that is of portable form, is often applied in office, for recording routine work; But no matter be which kind of blackboard, after large area writes writing on blackboard surface, need to be wiped and just can reuse.The method for deleting of current blackboard is more single, normally utilizes blackboard eraser to wipe.If blackboard only has a small amount of writing, then comparatively simple; When but if blackboard having large area writing, this kind of erase mode need eraser significantly vertical and horizontal saw the air, not only waste time and energy, and the dust dropped in erase process also easily directly enters the respiratory system of eraser, in the course of time, then respiratory disease can be there is.In addition, adopt the form of blackboard eraser erasing, be positioned at the writing of position, blackboard upper edge, if eraser's height is inadequate, then more difficult erasing, and part blackboard and be not easy to carry.
Utility model content:
In order to solve the problem, the utility model provides a kind of technical scheme: a kind of portable and collapsible blackboard, comprises the first Reelable blackboard, the second Reelable blackboard, hinge, fluorescent tube, handle, power line, bearing pin, connecting plate, spring, pole, base and pulley; Described first Reelable blackboard and the second Reelable blackboard two hinges are movably connected mutually; Described first Reelable blackboard is provided with fluorescent tube, and described first Reelable blackboard upper end is fixedly connected with jug; Described second Reelable blackboard is connected with power line, and on described second Reelable blackboard, global formation has ledge for chalk on blackboard and blackboard eraser groove; Described second Reelable blackboard lower end is fixedly connected with bearing pin; Described bearing pin lower end is fixedly connected with connecting plate; Described connecting plate lower end is fixedly connected with spring, and described connecting plate and spring are arranged in pole; Be fixedly connected with base under described pole, under described base, connect pulley.
As preferably, described pulley is provided with shoe.
As preferably, described spring is disk spring.
The beneficial effects of the utility model: its reasonable in design, modern design is unique, simple to operate, easy to use, be provided with pulley and substantially increase travelling performance, and shoe is set on pulley, slippage when it can be prevented static, height can be regulated by spring, by hinge, two blackboards are folded, can portability be substantially increased, also handle is set, be convenient to portable.
Accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
1-first Reelable blackboard; 2-second Reelable blackboard; 2a-ledge for chalk on blackboard; 2b-blackboard eraser groove; 3-hinge; 4-fluorescent tube; 5-handle; 6-power line; 7-bearing pin; 8-connecting plate; 9-spring; 10-pole; 11-base; 12-pulley.
Detailed description of the invention:
As shown in Figure 1, this detailed description of the invention by the following technical solutions: comprise the first Reelable blackboard 1, second Reelable blackboard 2, hinge 3, fluorescent tube 4, handle 5, power line 6, bearing pin 7, connecting plate 8, spring 9, pole 10, base 11 and pulley 12; Described first Reelable blackboard 1 and the second Reelable blackboard 2 two hinges 3 are movably connected mutually; Described first Reelable blackboard 1 is provided with fluorescent tube 4, and described first Reelable blackboard 1 upper end is fixedly connected with jug 5; Described second Reelable blackboard 2 is connected with power line 6, and on described second Reelable blackboard 2, global formation has ledge for chalk on blackboard 2a and blackboard eraser groove 2b; Described second Reelable blackboard 2 lower end is fixedly connected with bearing pin 7; Described bearing pin 7 lower end is fixedly connected with connecting plate 8; Described connecting plate 8 lower end is fixedly connected with spring 9, and described connecting plate 8 and spring 9 are arranged in pole 10; Described pole is fixedly connected with base 11 10 times, and described base connects pulley 12 11 times.
Wherein, described pulley 12 is provided with shoe; Described spring 9 is disk spring.
The using state of this device is: during use by power line to lamp tube power supply, provide illumination, folded by two pieces of blackboards, press down the effect that connecting plate pressing spring reaches compression time mobile by hinge, pulley is convenient mobile.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
