Description
The utility model relates to new type blackboard shading expansion bracket.Belong to human life need part, individual or household goods branch, the big class of furniture, desk by International Patent Classification (IPC) (IPC) division; Desk; The cabinet; Drawer; The general part of furniture, miscellaneous furniture; Miscellaneous accessory group, the support that blackboard or analog are used or the bearing technical group field of furniture.Classification number is A47B97/04.
At present, the existing and support of using about blackboard or analog that once had or the technology of bearing were all done very fruitful effort to the demand of new type blackboard shading expansion bracket, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Li Changming, Granted publication number is CN2207756Y, China Patent No. (ZL) is: No. 94242727.0 utility model title is the utility model patent of " Foldable multifunctional picture and text frame ", the technical scheme that is adopted.Support or the bearing technical elements used at blackboard or analog are routine of great value inventions, and it has solved the problem of Foldable multifunctional picture and text framves effectively.But still have some deficits, it also is difficult to solve the problem of blackboard reflective light.
The purpose of this utility model is to provide a kind of new type blackboard shading expansion bracket.To solve the problem of blackboard reflective light.
The purpose of this utility model is achieved in that the new type blackboard shading expansion bracket of this utility model.But mainly constitute by blackboard, link, blade, expansion link, connecting rod, spring, block, hook rotating ring, movable hook.But its blackboard, link, spring, hook rotating ring, movable hook are by selecting for use on the market.Its expansion link, connecting rod are rectangular shapes, use the steel material, through the machining manufacturing.Its blade is cuboid (hollow) shape, uses the steel material, through the machining manufacturing.Its block is the triangular prism shape, uses the steel material, through the injection moulding processing and manufacturing.Connecting rod adopts the screw method to be installed in the blade upper position, constitutes the rod-shape movable structure, and function has been to be connected effect with wall.Expansion link adopts the spring method of attachment to be installed in the interior location of blade, constitutes the rectangular shape moving structure, and function has been a telescopic action.Spring adopts welding method to be installed in the interior position of going up of blade, constitutes the rectangular shape spring structure, and function has been to make the expansion link telescopic action.Block adopts adhering method to be connected the external position of expansion link, constitutes the ladder-shaped fixed structure, and function has been a fixation.Hook adopts welding method to be connected the lower position of expansion link, constitutes the hook shape fixed structure, and function has been a fixation.But rotating ring adopts welding method to be connected the external position of blade, constitutes the toroidal movable structure, and function has been a migration.But movable hook adopts welding method to be connected the external position of rotating ring, constitutes the hook shape movable structure, and function has been a fixation.So just realized the purpose of this utility model.
The advantage of utility model: support or bearing technology that the utility model and original blackboard or analog are used have been compared three advantages and improvement;
The first, because the utility model has designed spring in technical scheme, institute is so that expansion link is flexible;
The second, but because the utility model has designed rotating ring in technical scheme, so removable;
The 3rd, because the utility model has designed expansion link in technical scheme, so scalable; Thereby just can more effectively solve the problem of blackboard reflective light.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the use structural representation of new type blackboard shading expansion bracket of the present utility model;
Fig. 2 is the sectional structure schematic diagram of new type blackboard shading expansion bracket of the present utility model;
The numbering of parts explanation in the schematic diagram: but 1 blackboard, 2 links, 3 blades, 4 expansion links, 5 connecting rods, 6 springs, 7 blocks, 8 hooks, 9 rotating rings, 10 movable hooks
In the optimum implementation of new type blackboard shading expansion bracket of the present utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, new type blackboard shading expansion bracket of the present utility model.But mainly constitute by blackboard 1, link 2, blade 3, expansion link 4, connecting rod 5, spring 6, block 7, hook 8 rotating rings 9, movable hook 10.Connecting rod 5 adopts the screw method to be installed in the upper position of chi 3, constitutes the rod-shape movable structure, and function has been to be connected effect with wall.Expansion link 4 adopts the spring method of attachment to be installed in the interior location of blade 3, constitutes the rectangular shape moving structure, and function has been a telescopic action.Spring 6 adopts welding method to be installed in the interior position of going up of blade 3, constitutes the rectangular shape spring structure, and function has been to make the expansion link telescopic action.Block 7 adopts adhering method to be connected the external position of expansion link 4, constitutes the ladder-shaped fixed structure, and function has been a fixation.Hook 8 adopts welding method to be connected the lower position of expansion link 3, constitutes the hook shape fixed structure, and function has been a fixation.But rotating ring 9 adopts welding method to be connected the external position of blade 3, constitutes the toroidal movable structure, and function has been a migration.But movable hook 10 adopts welding method to be connected the external position of rotating ring 9, constitutes the hook shape movable structure, and function has been a fixation.
Its dynamic structure: in force:
According to flexible principle, its blade 3 acts on blackboard by expansion link 4, thereby finishes the task of lucifuge.So just realized the purpose of this utility model.Thereby just can solve the problem of blackboard reflective light.
Below by using method, the utility model is done more detailed description:
The new type blackboard shading expansion bracket of this utility model is work like this:
In use, when in the class, teacher writes according to flexible principle, and its blade 3 acts on blackboard by expansion link 4, thereby finishes the task of lucifuge.
Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of spring workshop, take assembling to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
