Description
Technical field
The utility model relates to a kind of teaching aid, especially relates to a kind of teaching push type chalk holder.
Background technology
Chalk is school teacher's requisite educational aid of one that carries out writing on the blackboard in process of teaching.Chalk is generally all divided in carton by color, therefore need on dais, put multiple chalk holders, so not only can take limited space, dais, and make dais seem comparatively in disorder, in addition, when use, need to from different cartons, extract the chalk of the color of wanting, especially in the chalk holder of just having sealed off, chalk is closely placed, use compared with great strength and could extract chalk out, easily cause chalk fracture, and along with the chalk in chalk holder reduces, in chalk holder, remaining chalk just can be dilapidated simultaneously, be deposited in together, make taking of chalk very inconvenient.
Application publication number CN103799661A, the Chinese patent of Shen Qing Publication day 2014.05.21 discloses a kind of chalk holder, comprise box body, box body upper end is provided with lid, and lid one side is hinged on box body, and drawer that can pull is equipped with in the bottom of box body, in the box body of drawer top, be provided with dividing plate, dividing plate to the distance of box body upper port is 3: 1 with the distance ratio bottom box body, is covered with small sircle hole on dividing plate, and the diameter of small sircle hole is equivalent to the diameter of chalk.Its weak point is, on the dividing plate of this chalk holder, is covered with small sircle hole, and chalk is inserted in small sircle hole, therefore in the time taking chalk, hand can with chalk holder in chalk interfere collision, be easy to cause chalk to fracture, in addition, this chalk holder is unfavorable for the chalk sorting placement of different colours.
Utility model content
The utility model is the existing the problems referred to above of the chalk holder in order to solve prior art, provides a kind of simple in structure, can save space, dais, and can carry out sorting placement to the chalk of different colours, and chalk taking is with imparting knowledge to students and use push type chalk holder easily.
To achieve these goals, the utility model is by the following technical solutions:
A kind of teaching push type chalk holder, comprise box body and fixing lid, in described box body, be interval with some dividing plates, box body is separated into some independently chalk placed cavities by described dividing plate, between described fixing lid and box body, be provided with gap, this gap forms the chalk ejection door of chalk placed cavity, described chalk ejection door is provided with removable cover, described removable cover is hinged near a side and the fixing lid of fixing lid, removable cover overlaps with box body away from edge under a side of fixing lid, in described chalk placed cavity, be longitudinally provided with push pedal, described push pedal is fixedly connected with the inwall of chalk placed cavity by the first spring, chalk placed cavity is longitudinally provided with chute with respect to the opposite side inwall bottom of push pedal, in described chute, be provided with the transition linkage section sliding along chute, the outboard end of described transition linkage section is provided with compressing tablet, in chalk placed cavity, be also provided with diving board, described diving board is positioned at push pedal below, diving board one end is fixedly connected with the medial end of transition linkage section, the both sides inwall of the diving board other end and chalk placed cavity is rotationally connected, and diving board end underrun the second spring being fixedly connected with the medial end of transition linkage section is fixedly connected with chalk placed cavity bottom surface.The interior chalk for sorting placement different colours of chalk placed cavity in the utility model, the width of chalk placed cavity and the Breadth Maximum of chalk are suitable, in the time being placed with chalk in chalk placed cavity, chalk bottom contacts with diving board, push pedal meeting is pushed ahead chalk under the screen resilience effect of the first spring, due to the existence of the second spring, make monoblock diving board be skewed (diving board near chute is inclined upwardly), chalk foremost can be stuck between securing cover plate and diving board and can not push ahead under the pressure of the second spring, and while pressing lower sheeting, the second spring presses down, diving board part near chute declines, the chalk upper end and the cover plate that cause being positioned at are foremost thrown off, chalk can continue again entirety and push ahead until chalk foremost and box body crimping under the screen resilience effect of the first spring, unclamp after compressing tablet, the second spring is replied upper bullet, under the effect of the second spring restoring force, being positioned at chalk upper end foremost backs down removable cover and ejects from chalk ejection door, just expose outside the chalk upper end being positioned at foremost after the second spring recovery is original-pack, the chalk exposing is directly taken away, and now can under the pressure of the second spring, be stuck between securing cover plate and diving board and can not push ahead at chalk foremost.The utility model can be classified the chalk of different colours, and same color chalk can be placed separately, can mutually not pile up, reduce chalk holder taking up room to dais, make dais more clean and tidy, in addition, by can make chalk eject to " one puts by one " of compressing tablet, make taking of chalk very convenient.
As preferably, described removable cover is hinged by hinge and fixing hamper near a side of fixing lid.
As preferably, described the first spring has two, respectively upper and lower parallel being fixed between push pedal and the inwall of chalk placed cavity.The first spring has two, the stationarity can improve push pedal campaign time.
As preferably, between described push pedal and chalk placed cavity inwall, be provided with guiding mechanism, described guiding mechanism comprises the gathering sill on the chalk placed cavity inwall of being located at push pedal both sides and is located at the projection of push pedal both sides, and described projection is positioned at gathering sill and gathering sill is slidably matched.
As preferably, described compressing tablet is rounded, and compressing tablet and transition linkage section are homogeneity integrative-structure.
As preferably, the diving board other end is rotationally connected by the both sides inwall of rotating pin and chalk placed cavity.
As preferably, described fixing lid is transparent.Fixing lid is transparent, to observe surplus and the color classification of chalk in chalk holder.
Therefore the beneficial effect, the utlity model has is:
(1) in a box body, can be classified the chalk of different colours, and same color chalk can place separately, can mutually not pile up, not only reduce chalk holder to the taking up room of dais, make dais more clean and tidy, and make taking of chalk more convenient;
