Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-4, a device for telescopic ideological and political education and teaching comprises a first writing board 1, a cuboid cavity 16 is arranged in the first writing board 1 in a penetrating manner, three fixing plates 14 are fixedly arranged on the inner bottom wall of the first writing board 1 at the bottom end of the cavity 16 at equal intervals, the opposite side surfaces of the fixing plates 14 at the two sides are fixed on the inner side wall of the first writing board 1, a second writing board 2 is inserted between two adjacent fixing plates 14 in a sliding manner, a third writing board 3 is inserted between the other two adjacent fixing plates 14 in a sliding manner, one end of the third writing board 3 and one end of the second writing board 2 are both arranged outside the cavity 16 in the first writing board 1, limit blocks 13 are fixedly arranged on the upper surfaces of the other ends of the third writing board 3 and the second writing board 2 in the cavity 16 in the first writing board 1, shielding plates 15 are fixedly arranged at the two ends of the inner top wall of the first writing board 1 in the cavity 16, wherein the second writing board 2 is the same as the third writing board 3 in structure and size, and the horizontal plane at the top end of the limiting block 13 is higher than the horizontal plane at the bottom end of the shielding plate 15. When the second writing board 2 and the third writing board 3 are pulled out from the cavity 16 in the first writing board 1, the shielding plate 15 blocks the limiting block 13, so that the second writing board 2 or the third writing board 3 can be prevented from falling out from the cavity 16 in the first writing board 1 when being pulled.

Slope fixedly on the outer diapire of first clipboard 1 is equipped with two dead levers 7, two dead levers 7 keep away from jointly fixed being equipped with ring 8 on the bottom of first clipboard 1, support column 9 is installed to the screw thread in the ring 8, and support column 9 sets up between two dead levers 7, the fixed rubber column 10 that is equipped with that bonds on the support column 9 top, rubber column 10 keeps away from the top of support column 9 and the outer diapire of first clipboard 1 and contacts, vertical fixation is equipped with circular shape bottom plate 11 on the support column 9 bottom. Through rotating support column 9 or ring 8, can adjust the length that spills of 8 upper end support columns 9 of ring, and then adjust the use height of this device for telescopic ideological and political education teaching.

This device is used in telescopic ideological and political education teaching, when leaking the one end outside cavity 16 in first clipboard 1 through pulling second clipboard 2 and third clipboard 3, can with first clipboard 1 in the cavity 16 inside partial second clipboard 2 and third clipboard 3 pull out, all can carry out the writing on first clipboard 1, second clipboard 2 and third clipboard 3, can enlarge the writing area of writing, and after the use, promote second clipboard 2 and third clipboard 3 again, can accomodate second clipboard 2 and third clipboard 3 in first clipboard 1, reduce the writing area of this device is used in telescopic ideological and political education teaching, let this device is used in telescopic ideological and political education also occupy less space.

Example 2

In example 1, when the retractable type apparatus for ideological and political education and teaching is not used, and the second writing board 2 and the third writing board 3 are accommodated in the cavity 16 of the first writing board 1, since there is no limit mechanism between the second writing board 2 and the third writing board 3 and the first writing board 1, when an external force is applied to the device for retractable ideological and political education, the second writing board 2 or the third writing board 3 is very easily slid out of the cavity 16 of the first writing board 1, as shown in FIGS. 1 to 3, as another preferred embodiment of the present invention, the difference with embodiment 1 lies in, all fixedly being equipped with first limiting plate 4 on the second clipboard 2 outside cavity 16 and the third clipboard 3 top, all vertically fixed being equipped with second limiting plate 5 on the relative side both ends of first limiting plate 4 and first clipboard 1, all bonding fixedly is equipped with rubber pad 6 on the relative side of two second limiting plate 5. When not using this device for telescopic ideological and political education teaching, second clipboard 2 and third clipboard 3 are accomodate in first clipboard 1 during cavity 16's inside, the 5 blocks of second limiting plate 5 at 4 both ends of first limiting plate are on first clipboard 1 upper and lower both ends, again because the setting of rubber pad 6, can increase the frictional force between second limiting plate 5 and the first clipboard 1, when this device for telescopic ideological and political education teaching is touchd to external force, can prevent roll-off in the cavity 16 of second clipboard 2 or third clipboard 3 follow first clipboard 1.

Example 3

In embodiment 1, when removing this device for telescopic ideological and political education teaching, because there is not moving mechanism, this device for telescopic ideological and political education teaching is very inconvenient to remove, refer to fig. 1 and 3, as the utility model discloses a another preferred embodiment, as the difference of embodiment 1 lies in, bottom plate 11 and the fixed universal wheel 12 that is equipped with of the side edge equidistance that the support column 9 was carried on the back mutually, is equipped with the service brake on the universal wheel 12. This device is used in telescopic ideological and political education teaching is removed to the setting of universal wheel 12 makes things convenient for people very much to after this device is used in telescopic ideological and political education teaching removes appointed position, utilize the service brake to fix this device is used in telescopic ideological and political education teaching, prevent that this device is used in telescopic ideological and political education teaching from sliding.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
