Problems solved by technology

[0002] It is very difficult to fix teaching equipment on the vertical facade without drilling and nailing on the vertical facade
In actual teaching, if you want to fix the teaching device on the wall or the vertical colored demonstration board, most of them can only be bundled with tape, or nails are nailed on the side of the colored demonstration board to facilitate fixing the teaching device or hanging it. Teaching legend, these methods will not hurt the colored demo board on the surface, but when it is removed, there are often glue marks left on the colored demo board, which are very difficult to remove; some colored demo boards are made of metal and can be removed. The suction force of the magnet block on the metal colored demonstration board is used to assist the fixing of teaching equipment, but the magnet is easy to slide down on the smooth metal decorative board, which often scratches the paint surface of the colored demonstration board; ordinary suction cups can also be used Adsorbed on the surface of the colored demo board, because the dust on the surface of the colored demo board is not easy to be completely removed, it is easy to cause air leakage from the sucker adsorbed on the surface of the colored demo board. Therefore, it is difficult to ensure the long-term Time to fix teaching utensils on the vertical façade

Abstract

The invention discloses a positioning device capable of fastening a teaching instrument on a vertical surface. The positioning device comprises a positioner housing, an anti-sliding rubber ring, a low-viscosity elastic rubber ring, a pull rod, a spring and a wrench. The positioning device is characterized in that a pressure plate is arranged on the lower surface of the positioner housing, a through hole is formed in the upper surface of the positioner housing; the through hole communicates with an inner cavity; an inner cavity opening is formed underneath, and the inner cavity opening is connected with the inner round edge of a convex ring; the bottom surface of the pressure plate is arranged on the outer ring of the convex ring; the anti-sliding rubber ring is fixedly arranged on the bottom surface of the convex ring; the low-viscosity elastic rubber ring is fixed with the bottom surface of the pressure plate; a shaft hole is formed in the upper end of the pull rod, and circular discmagnetic steel is arranged at the lower end of the pull rod; a sealing rubber ring is arranged in the middle of the circular disc magnetic steel; an anti-sliding sheet is fixedly arranged on the bottom surface of the circular disc magnetic steel; one end of the wrench is equipped with a fork slot and a fork head; a rotary shaft is fixedly arranged on the fork head; the spring sleeves the pull rod;and the pull rod gets out from the through hole and the rotary shaft passes through the shaft hole, so that the wrench and the pull rod are connected together in a penetrating mode. The positioning device can be adsorbed on the vertical surface, including an uneven vertical surface, of any material for a long time.
