Abstract
The utility model discloses a parent-subsidiary type turnover blackboard. The parent-subsidiary type turnover blackboard comprises a large blackboard, a small blackboard, a guide rail, a roller device, a hanging rod, partition boards, clamp rings, limited blocks and torsion springs; the guide rail is arranged on the upper edge of the large blackboard; the roller device is arranged in the guide rail; the roller device comprises a roller bracket and two rollers mounted on the roller bracket; a clamping groove is formed on the roller bracket between the two rollers and is connected with the hanging rod arranged at the upper end of the small blackboard in a meshed manner; two turnover brackets are fixedly mounted at the two ends of the large blackboard respectively; one ends of the two torsion springs are fixed on the turnover brackets through the two limited blocks; the partition boards are fixed at the other ends of the torsion springs; two placing grooves are formed on the side surfaces of the two ends of the small blackboard respectively; and the partition boards are just meshed with the placing grooves. The small blackboard can be moved and turned over on the large blackboard at random and does not influence normal use of the large blackboard; and the parent-subsidiary type blackboard is simple in structure and convenience in operation, and has very high practicability and popularization value.
Description
Technical field
The utility model relates to a kind of blackboard, more particularly relates to a kind of primary-secondary type blackboard that can move and overturn along the blackboard surface.
Background technology
We use a little side of blackboard through regular meeting in learning process at ordinary times as the place of message or account, such as writing job content, accent class notice or the like.And when using projection screen, can cover a very big plate blackboard more, so just reduced originally to write the space unintentionally with regard to little blackboard, therefore our daily study has been brought very big not convenient property, we think a kind ofly just can effectively address these problems with the small blackboard blackboard disjunctor if can design.
Summary of the invention
To achieve these goals, the utility model provides a kind of primary-secondary type turnover blackboard, the small blackboard that by the roller devices that is provided with on the big blackboard is can move left and right, the turnover bracket that the side is provided with can allow small blackboard overturn, so just realized not taking the area of big blackboard, small blackboard can also arbitrarily drag and overturn.
A kind of primary-secondary type turnover blackboard, comprise big blackboard, small blackboard, guide rail, roller devices, peg, dividing plate, collar, limited block and torsion spring, the top edge of described big blackboard is provided with a guide rail, one roller devices is set in the described guide rail, described roller devices comprises a rolling wheel support and is installed in two rollers on the rolling wheel support, rolling wheel support between two rollers is provided with a draw-in groove, and described draw-in groove coincide with the peg that the small blackboard upper end is provided with and links to each other; Described big blackboard two ends fixedly mount a turnover bracket respectively, fix an end of two torsion springs on the described turnover bracket by two limited blocks, the other end of described torsion spring is fixed a dividing plate, described small blackboard two ends lateral location is respectively equipped with two putting slots, and described dividing plate and described putting slot just in time coincide.
Also fix a collar on the described torsion spring respectively, described collar and described dividing plate can be to rotating;
Described putting slot is the groove that is parallel to the small blackboard surface;
Described small blackboard lower end medial surface is provided with roller;
Described peg is to fix a ball on the cylindrical bar, and described ball diameter is greater than described draw-in groove diameter.
The beneficial effects of the utility model are: small blackboard can arbitrarily move and upset on big blackboard, does not influence the normal use of big blackboard, and this blackboard structure is simple, easy to operate, has very high practicality and promotional value.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of turnover bracket;
Fig. 3 is the structural representation of small blackboard;
Fig. 4 is the structural representation of roller devices.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1～shown in Figure 4, a kind of primary-secondary type turnover blackboard, comprise big blackboard 1, small blackboard 2, guide rail 3, roller devices 4, peg 5, dividing plate 11, collar 9, limited block 8 and torsion spring 10, the top edge of described big blackboard 1 is provided with a guide rail 3, one roller devices 4 is set in the described guide rail 3, described roller devices 4 comprises a rolling wheel support 15 and is installed in two rollers 13 on the rolling wheel support 15, rolling wheel support 15 between two rollers 13 is provided with a draw-in groove 14, and described draw-in groove 14 coincide with the peg 5 that small blackboard 2 upper ends are provided with and links to each other; Described big blackboard 1 two ends fixedly mount a turnover bracket 6 respectively, pass through a fixedly end of torsion spring 10 of two limited blocks 8 on the described turnover bracket 6, the other end of described torsion spring 10 is fixed a dividing plate 11, described small blackboard 2 two ends lateral location are respectively equipped with two putting slots 7, and described dividing plate 11 just in time coincide with described putting slot 7.
Also fix a collar 9 on the above-mentioned torsion spring 10 respectively, described collar 9 and described dividing plate 11 can be to rotating; Described putting slot 7 is for being parallel to the groove on small blackboard 2 surfaces; Described small blackboard 2 lower end medial surfaces are provided with roller 12; Described peg 5 is fixed a ball on the cylindrical bar, and described ball diameter is greater than described draw-in groove 7 diameters.
When we at ordinary times when using blackboard of the present utility model, peg 5 on the small blackboard 2 hangs on the big blackboard 1 by the draw-in groove on the roller devices 4 14, because small blackboard 2 bottoms also are provided with roller 12, like this small blackboard 2 just can be about reaching on the big blackboard random mobile purpose.
This device is provided with turnover bracket 6 in the left and right edges of big blackboard 1, when small blackboard 2 moves to left or is shifted to the right to edge, putting slot 7 on the small blackboard 2 is just in time aimed at the dividing plate 11 on the turnover bracket 6, because putting slot 7 just in time coincide with dividing plate, turnover bracket 6 forms one with small blackboard 2 like this.When we need rotate small blackboard, only small blackboard 2 need be moved on a little, its peg 5 is come out, because torsion spring 10 also has certain elastic force can not damage turnover bracket 6 in draw-in groove 14.The collar 9 of turnover bracket 6 can be separately fixed at the positive and negative both sides of small blackboard 2, small blackboard 2 is clamped, more stable after making small blackboard 2 come out in the draw-in groove 14, so just can reach small blackboard 2 can be around the random purposes of upset of turnover bracket 6.
Embodiment of the present utility model has just described its architectural feature and principle, may have certain variation under the prerequisite that does not break away from concept of the present utility model, all should be within protection scope of the present invention.
