Accompanying drawing explanation
Fig. 1 is main part structural representation of the present utility model.
Fig. 2 is anchor structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, 2, the utility model comprises housing 2, push pedal 6, elastic plate 8, lock and fixture 10.
Described housing 2 is fixed on wall or on other body surfaces, its lower ending opening, housing about 2 two sidewalls are provided with the perforate adapted with described elastic plate 8 shape, described elastic plate 8 is positioned at this perforate, elastic plate 8 upper end and described housing 2 are fixedly connected, elastic plate 8 lower end is provided with inwardly outstanding interior convex edge 9, and the lower end of interior convex edge 9 is provided with inclined-plane.
Described push pedal 6 is positioned at the top of housing 2 inner chamber, is provided with the transverse slat (not shown) be fixed on housing 2 below push pedal 6, is used for holding push pedal 6.Push pedal 6 main part is front wide and rear narrow trapezoidal, and push pedal 6 body front end is provided with button 1, and described housing 2 antetheca is provided with the perforate adapted with described button 1 shape, and button 1 stretches out in this perforate.
On the position that described elastic plate 8 upper end medial surface contacts with described push pedal 6, be provided with the inclined-plane 7 adapted with push pedal 6 side, when promoting push pedal 6 backward, by the acting in conjunction on push pedal 6 side and this inclined-plane 7, by extrapolated for elastic plate 8.
Described locking fixes on described housing 2 antetheca, comprise lock core 5 and dead bolt 4, described dead bolt 4 to be fixed on lock core 5 and vertical with lock core 5, described push pedal 6 button 1 is provided with the breach 3 adapted with described dead bolt 4, when rotational lock core 5, dead bolt 4 rotates thereupon, when dead bolt 4 turns in described breach 3, thus push pedal 6 can be pinned.
According to the difference of teaching aid character, described fixture 10 can be a position of teaching aid, also can be the parts be fixedly connected with teaching aid.Described fixture 10 arranged on left and right sides is provided with the depression 11 adapted with convex edge 9 in described elastic plate lower end.
Operating process is as follows: during use, described fixture 10 is upwards pushed away from described housing 2 lower end, push elastic plate 8 to two ends by the inclined-plane of elastic plate 8 lower end, push away fixture 10 on continuing, the interior convex edge 9 of elastic plate 8 lower end is by the groove that is stuck in fixture 10; When needs take off teaching aid, press described button 1, promote push pedal 6 inwards, by the acting in conjunction on the inclined-plane of push pedal 6 and elastic plate 8 upper end, push elastic plate 8 to both sides, thus described fixture 10 can take out smoothly; When teaching aid pins by needs, insert key rotation lock core 5, can be pinned in the breach 3 dead bolt 4 being inserted into push pedal button.
It should be noted that; particular of the present utility model has been described in detail the utility model; for a person skilled in the art, the various apparent change carried out it when not deviating from spirit and scope of the present utility model is all within protection domain of the present utility model.
