2, the baffle of the utility model can limit riser, to guarantee that multiple risers form plane, write more It is smooth；The knob at the baffle back side can be pulled after the completion of writing, the connecting rod one of link mechanism is moved with baffle, and connecting rod two is moved along sliding sleeve Dynamic, telescopic rod stretches, and baffle leaves riser, releases the limit to riser, and the riser chosen may be reversed at this time, using this structure, Riser rotation is convenient, limit is reliable.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model embodiment.

Fig. 2 is the backside structure figure of the utility model embodiment.

Fig. 3 is the structural exploded view of the utility model embodiment.

In figure, 1, bracket, 11, frame, 12, supporting leg, 121, castor, 21, fixed plate, 22, riser, 23, baffle, 24, Knob, 251, connecting rod one, 252, connecting rod two, 253, sliding sleeve, 261, outer tube, 262, inner prop.

Specific embodiment:

In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality It is described in detail with novel.

As illustrated in fig. 1-3, the memorizing english words aided education demonstration board of the present embodiment, including bracket 1 and clipboard, Bracket 1 includes the frame 11 and supporting leg 12 of mounting plate 21 and movable plate, and the bottom of supporting leg 12 is equipped with castor 121, Clipboard includes fixed plate 21 and movable plate, the fixed interlocking of fixed plate 21 in the frame 11 of bracket 1, movable plate include it is multiple with The riser 22 that bracket 1 is rotatablely connected and the baffle 23 that riser 22 is limited, wherein the two of two sides in movable plate A riser 22 is fixed on bracket 1, cannot be rotated again；The upper end of baffle 23 and the upper end of bracket 1 pass through a set of connecting rod machine Structure connection, the lower end of baffle 23 is connect with the lower end of bracket 1 by telescopic rod.

Aforementioned link mechanism includes the connecting rod 1 for being hinged on 23 upper end of baffle and the hinged connecting rod two of connecting rod 1 252 and be fixed on bracket 1 upper end sliding sleeve 253, connecting rod 2 252 can move left and right along sliding sleeve 253.Telescopic rod includes two A outer tube 261 and inner prop 262 to connect together, wherein the extension end of inner prop 262 is fixed on the riser 22 not being able to rotate, outside The extension end of pipe 261 is fixed on baffle 23, and outer tube 261 can be mobile relative to inner prop 262.Link mechanism and telescopic rod are in baffle 23 On to be symmetrically arranged be two groups, the stationarity of the movement of baffle 23 can be increased in this way.The back side of baffle 23 is equipped with knob 24, it is convenient for being manually operated；The front of baffle 23 is in preceding convex, and the back side of riser 22 is propped up with this.The front of riser 22 It is writing surface with the back side.

In classroom teaching, due to having biggish writing surface in fixed plate 21, and fluent writing can guarantee, therefore fixed Plate 21, which can be used as normal common demonstration board, to be come, convenient for the lecture contents in student viewing fixed plate 21.

In use, since the front and back sides of riser 22 are writing surface, without the positive and anti-of intended distinction riser 22 Face.On each riser 22 can vertical write words translation or sentence translation, the knob at 23 back side of baffle can be pulled after the completion of writing 24, one 251, connecting rod of link mechanism move with baffle 23, and connecting rod 2 252 is under the pulling of connecting rod 1 along sliding sleeve 253 is mobile, and telescopic rod is stretched, and outer tube 261 is displaced outwardly with respect to inner prop 262, and baffle 23 leaves riser 22, relieves to perpendicular The riser 22 chosen may be reversed in the limit of plate 22 at this time, and using this structure, the rotation of riser 22 is convenient, limit is reliable, then by learning Raw random selection riser 22 come say or it is silent go out word, sentence, increase the interest of study with this, can also take this opportunity procuratorial theory It is raw whether really to have grasped knowledge.In addition, word laterally can also have been write along multiple risers 22, can be taken out at random after writing It selects several risers 22 to be overturn, is then remembered by students and be reversed past word or letter, mobilizing students are come with this Enthusiasm, make teaching classroom more rich and varied, be more convenient for carrying out rapid memory and inspection.

When not needing to overturn riser 22, then knob 24 is pushed to reset baffle 23, baffle 23 will push connecting rod one 251 rotations, meanwhile, connecting rod 1 pushes connecting rod 2 252 to move along sliding sleeve 253, and the protrusion of 23 front of baffle just contradicts riser 22 and riser 22 is limited, because writing physical strength is smaller, and while writing be writing power is imposed to each riser 22 respectively, and Baffle 23 is monolith setting, therefore baffle 23 can guarantee that multiple risers 22 form plane, make to write steady smoothness.It can also increase Frictional force between connecting rod 2 252 and sliding sleeve 253, make baffle 23 can not free movement, need by the outer of enough size Power can disengage it from 22 back side of riser.

Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model It protects in range.Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
