Problem through above -mentioned technical scheme, among the fine solution prior art.
Description
Technical field
The utility model relates to educational aid field, is specifically related to a kind of folding blackboard.
Background technology
Blackboard is a kind of very common educational aid, conveniently carry now, occurred that some can carry blackboard on the market, but the carried blackboard ubiquity occurred on the market and area can be utilized less and problem that is that make the scope of application narrow without supporting mechanism.
Utility model content
The purpose of this utility model is to provide a kind of folding blackboard, has and can utilize the advantage that area is large, applicability is high, solve the problems of the prior art.
To achieve these goals, the technical scheme taked of the utility model is as follows:
A kind of folding blackboard, comprise blackboard main body, described blackboard main body comprises the first blackboard and the second blackboard and blackboard module, first blackboard both sides are provided with chute, second blackboard is provided with two slide blocks in both sides behind, described two slide blocks snap in two chutes respectively, and the second blackboard can be moved relative to the first blackboard; Described first blackboard and the second blackboard are all formed by two blackboard module chain connections, and described blackboard main body is also provided with sleeve, and described sleeve top is fixed with the top of bracing frame, and support frame as described above is height adjustable stand.
Particularly, support frame as described above comprises adjusting rod and fixed mechanism, and described adjusting rod is Height Adjustable adjusting rod, and the top of described adjusting rod is fixedly connected with sleeve top; Described fixed mechanism comprises at least three fixed heads, and described fixed head top is flexibly connected with bottom adjusting rod, and described fixed head is provided with fixing card, and is connected with fixing axis; Described fixing card is vertical plate and the laterally extending structure having reverse L template in vertical plate bottom.
Further, described blackboard main body is provided with handheld component.
Further, two blackboard module backside of described composition first blackboard are respectively equipped with pin thread band and box band.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is provided with two blackboards, and two blackboards can be overlaped by the mode of sliding, and also deployable use, makes usable floor area larger.
(2) in the utility model, two blackboards are all made up of two hinged blackboard modules, make blackboard entirety collapsible, and like this just make, blackboard entire area is less, carries more convenient.
(3) the utility model is provided with bracing frame, and bracing frame is Height Adjustable, when making to need when going out to use blackboard, directly bracing frame can be stood on the ground, and not needing look round for suspension arrangement again again, such applicability is just higher, can not by the impact of external condition.
(4) be provided with handheld component in the utility model, make to carry and further facilitate.
(5) the utility model structure is simple, with low cost, is worth large-scale promotion to use.

Wherein, Reference numeral title is as follows: 1-first blackboard, 2-second blackboard, 3-chute, 4-sleeve, 5-bracing frame, 51-adjusting rod, 52-fixed head, the fixing card of 53-, 6-handheld component, 7-pin thread band, 8-box band, 9-blackboard module.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment 1
As shown in Figures 1 to 3, a kind of folding blackboard, comprises blackboard, lower blackboard and the vertical sleeve 4 arranged, and described upper blackboard is formed by two upper blackboard module chain connections, and described lower blackboard is formed by two lower blackboard module chain connections; Described upper blackboard both sides are all provided with chute 3, and described lower blackboard both sides are all provided with slide block, and described two slide blocks snap in two chutes respectively, and can slide in chute.Described two upper blackboard module chain connection positions are corresponding with two lower blackboard module chain connection positions.
Described upper blackboard is fixed with sleeve, in described sleeve, is provided with bracing frame 5.Support frame as described above comprises adjusting rod 51 and fixed mechanism, and described adjusting rod and vertical sleeve top are fixed, and are connected with fixed mechanism bottom described adjusting rod.Described adjusting rod is Height Adjustable adjusting rod.
Described fixed mechanism comprises the identical fixed head 52 of three specifications and fixing card 53, and be provided with semi-ring bottom described adjusting rod, three fixed head tops are provided with the first through hole, and three fixed heads are penetrated in described semi-ring.Described three fixed head tops are also all provided with fixing card, and one end of described fixing card and three fixed heads are all provided with the second through hole, be installed with rotating shaft fixing card can be rotated by opposing fixed plate 360 deg in the second through hole of fixing card and fixed head.The other end of described fixing card is laterally extending reverse L template, makes fixing card to block fixed head.
When not using, lower blackboard and upper blackboard overlap, then by upper blackboard and lower blackboard simultaneously to folded.When using, upper blackboard and lower blackboard are launched, and by lower blackboard toward drop-down.Bracing frame is pulled out in vertical sleeve, and with fixing card, each fixed head is blocked, make iron bar present 3-D triangle and reach support effect, so just can play a supporting role to blackboard main body.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, described upper blackboard top is also provided with handheld component 6, and blackboard can be mentioned by user.The described upper blackboard back side is provided with the box band 8 and pin thread band 7 that can mutually fasten.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
