Description
Technical field
The utility model relates to teaching aid technical field, particularly a kind of mobile folding blackboard.
Background technology
Although multimedia teaching is by more application, the effect of blackboard remains irreplaceable.Existing blackboard is still to be fixedly installed in teacher's front wall.
Along with development in science and technology, moving type blackboard is widely used.Moving type blackboard uses flexibly, applied range.But the height of existing moving type blackboard is non-adjustable, and it is comparatively large to take up room when depositing, and its use is restricted.
Utility model content
The purpose of this utility model is to provide one to take up room little, easy to use, adjustable for height mobile folding blackboard, non-adjustable and take the problem of the useful space when depositing for solving moving type blackboard height in prior art.
The technical solution of the utility model is:
A kind of mobile folding blackboard, comprise blackboard panel 3, the back side of described blackboard panel 3 is articulated and connected four poles be parallel to each other 2, the other end of each pole 2 is articulated and connected bracing frame 9, the back side of support frame as described above 9 is provided with teaching aid storage box 11, and the bottom of support frame as described above 9 is provided with several rows travelling wheel 10; Wherein described in two, between pole 2, connecting rod 12 is set, described connecting rod 12 is fixed with the first pulley 4, support frame as described above 9 is fixed with the second pulley 1, rope 8 is walked around vertical drop after the first pulley 4, second pulley 1 respectively and is wound on the rope winder 6 that is fixed on support frame as described above 9.
As a kind of preferred embodiment, described first pulley 4 is arranged at the middle part of connecting rod 12.
As a kind of preferred embodiment, in four poles 2, the line of every two poles 2 four end points is rectangular.
As a kind of preferred embodiment, described second pulley 1 15-30cm higher than the most top pole 2.
Pole 2 and connecting rod 12 are for supporting blackboard panel 3.
The utility model mobile folding blackboard, presses close to bracing frame inwall after upwards rising.
When folding (rise) blackboard panel of needs, (hand cranking handle) rotates rope winder, and rope moves vertically downward, pulls each pole to move up, and then pulls blackboard panel to move up, stop operating after putting in place.
When needs put down blackboard panel, people is non-return for making rope winder throw off, blackboard panel can naturally launch (whereabouts) under Gravitative Loads, and energy manual control blackboard panel falling speed, can recover non-return after putting in place, blackboard panel can be still in required height, namely, not only collapsible but also adjustable height, is applicable to the teacher of different height.
The beneficial effects of the utility model are:
The utility model mobile folding blackboard structure is simple, designs ingenious, the utility model height that adjustable blackboard panel is extremely required in certain scope, and the utility model effectively can save space.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the plan structure schematic diagram of the utility model Folding blackboard.
Detailed description of the invention
Embodiment 1
As shown in Figure 1 and Figure 2, the utility model mobile folding blackboard, comprise blackboard panel 3, the back side of described blackboard panel 3 to be articulated and connected four poles be parallel to each other 2 by the first hinge 5, in four poles 2, the line of every two poles 2 four end points is rectangular, that is, four pole 2 end points line formation cuboid-type successively.
The other end of each pole 2 to be articulated and connected bracing frame 9 by the second hinge 7, and the first hinge 5 and the second hinge 7 can be the same or different.
The back side of support frame as described above 9 is provided with teaching aid storage box 11, and the bottom of support frame as described above 9 is provided with four travelling wheels 10, arranges road wheel 10, makes blackboard of the present utility model removable.
Arrange connecting rod 12 between pole 2 described in two, the centre of described connecting rod 12 is fixed with the first pulley 4, support frame as described above 9 is fixed with the second pulley 1, second pulley 1 15-30cm higher than the most top pole 2.Rope 8 is walked around vertical drop after the first pulley 4, second pulley 1 respectively and is wound on the rope winder 6 that is fixed on support frame as described above 9.
The utility model mobile folding blackboard, presses close to bracing frame inwall after upwards rising.
When folding (rise) blackboard panel of needs, (hand cranking handle) rotates rope winder, and rope moves vertically downward, pulls each pole to move up, and then pulls blackboard panel to move up, stop operating after putting in place.
When needs put down blackboard panel, people is non-return for making rope winder throw off, blackboard panel can naturally launch (whereabouts) under Gravitative Loads, and energy manual control blackboard panel falling speed, can recover non-return after putting in place, blackboard panel can be still in required height, namely, not only collapsible but also adjustable height, is applicable to the teacher of different height.
