综上所述，本实用新型能够将白板和黑板相结合，并实现灵活的双面转换，当需要当需要书写时使用黑板，实现一板两用，延长其使用寿命，节约使用成本。In summary, the utility model can combine a whiteboard and a blackboard, and realize flexible double-sided conversion, and use the blackboard when writing is required, so that one board can be used for two purposes, prolonging its service life, and saving use costs.
如图2所示，一个优选方案中，所述第二轴为直线轴，且通过黑板边框上的第三容置槽8延伸至所述双面板的上端边沿上；或者，如图3所示，所述第二轴为“U”弯折件，且“U”弯折件叩设在所述第二容置槽的上边框处。在本方案中，提供了两种设置第二轴的方案中，第一种方案中第二轴为直线轴，生产较为简单，但是装配时较为繁琐，需要在黑板边框上设置第三容置槽，以便能够将多个双面板放平至于黑板面处于同一平面；第二种方案中，将第二轴设置成“U”弯折件，生产较为繁琐，但是装配简单，只需要按上述描述装配即可，不需要另开第三容置槽。在实际应用中，可以根据需要，选择其中一种方案进行生产和装配。As shown in Figure 2, in a preferred solution, the second axis is a linear axis, and extends to the upper edge of the double-sided panel through the third accommodating groove 8 on the frame of the blackboard; or, as shown in Figure 3 , the second shaft is a "U" bending piece, and the "U" bending piece is tapped on the upper frame of the second accommodating groove. In this scheme, two schemes for setting the second axis are provided. In the first scheme, the second axis is a linear axis, and the production is relatively simple, but the assembly is more cumbersome, and a third accommodating slot needs to be set on the blackboard frame , so that multiple double panels can be laid flat so that the blackboard surface is on the same plane; in the second solution, the second axis is set as a "U" bending piece, which is more cumbersome to produce, but the assembly is simple, and only needs to be assembled according to the above description That is, there is no need to open a third accommodating tank. In practical applications, one of the solutions can be selected for production and assembly according to needs.
如图3所示，一个优选方案中，还包括：支撑杆9，其一端枢接设置在所述旋转板的内侧壁上，所述支撑杆的另一端枢接设置在第二容置槽的底部，且所述支撑杆的长度≤所述多个双面板的宽度的1/2。在上述各方案中，旋转板相对第二容置槽较为灵活，没有直接的连接机构，只是在需要对其固定时，嵌入第二容置槽中，因此，在需要拉出旋转板时，可能因为用力过猛，对其造成损伤，存在一定弊端；在本方案中，设置了支撑杆结构，不仅对旋转板起到支撑的作用，还对其进行了限位，使其不会被拉出第二容置槽的距离过大，保护本方案的整体结构，延长其使用寿命。As shown in Figure 3, in a preferred solution, it also includes: a support rod 9, one end of which is pivotally arranged on the inner side wall of the rotating plate, and the other end of the support rod is pivotally arranged on the second accommodating groove The bottom, and the length of the support rod is ≤ 1/2 of the width of the plurality of double panels. In the above-mentioned solutions, the rotating plate is more flexible relative to the second accommodating groove, and there is no direct connection mechanism. It is only embedded in the second accommodating groove when it needs to be fixed. Therefore, when the rotating plate needs to be pulled out, it may Because of excessive force, it will be damaged, which has certain disadvantages; in this scheme, a support rod structure is set, which not only supports the rotating plate, but also limits it so that it will not be pulled out The distance of the second accommodating tank is too large, which protects the overall structure of the scheme and prolongs its service life.
如图1所示，一个优选方案中，所述容置槽的开口宽度至少为所述黑板的长度的0.5倍。在本方案中，容置槽的开口宽度决定了嵌入其中的过个双面板所组成的投影的面积，应满足现有投影的需要。As shown in FIG. 1 , in a preferred solution, the opening width of the accommodating groove is at least 0.5 times the length of the blackboard. In this solution, the width of the opening of the accommodation groove determines the area of the projection formed by the two double panels embedded in it, which should meet the needs of the existing projection.
如图3所示，一个优选方案中，还包括：橡胶圈10，其设置在第二容置槽的内侧壁上；以及把手11，其设置在所述旋转板的外侧壁上。橡胶圈用于辅助固定旋转板，使其在不受直接的外力作用时，不会从第二容置槽内滑脱。As shown in FIG. 3 , a preferred solution further includes: a rubber ring 10 disposed on the inner side wall of the second accommodating groove; and a handle 11 disposed on the outer side wall of the rotating plate. The rubber ring is used to assist in fixing the rotating plate so that it will not slip out of the second accommodating groove when it is not subjected to direct external force.
一个优选方案中，所述第一容置槽的深度与所述多个双面板中任一双面板的宽度的差值为1-3cm。In a preferred solution, the difference between the depth of the first accommodating groove and the width of any one of the multiple double-sided panels is 1-3 cm.
如图3所示，一个优选方案中，还包括：磁铁12，其设置在第二容置槽的底部；长条形铁片13，其设置在所述旋转板的内侧壁上。在书写过程中，不可避免的会引起多个双面板的轻微振动，从而带动旋转板振动，因此，有可能造成旋转板在振动作用下滑脱出第二容置槽，本方案中，通过磁铁和长条形铁片之间磁力固定作用，将旋转板固定在第二容置槽内，避免上述情况的发生。As shown in FIG. 3 , in a preferred solution, it also includes: a magnet 12 disposed at the bottom of the second accommodating tank; and a strip-shaped iron piece 13 disposed on the inner side wall of the rotating plate. In the process of writing, it will inevitably cause slight vibrations of multiple double-sided boards, which will drive the rotating board to vibrate. Therefore, the rotating board may slide out of the second storage slot under the action of vibration. The magnetic fixation effect between the bar-shaped iron sheets fixes the rotating plate in the second accommodating groove, avoiding the occurrence of the above-mentioned situation.
尽管本实用新型的实施方案已公开如上，但其并不仅仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本实用新型的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本实用新型并不限于特定的细节和这里示出与描述的图例。Although the embodiment of the present utility model has been disclosed as above, it is not limited to the use listed in the description and the implementation, and it can be applied to various fields suitable for the present utility model. For those familiar with the art, Further modifications can be readily effected, so the invention is not limited to the specific details and examples shown and described herein without departing from the general concept defined by the claims and their equivalents.
