Description
Technical field
The utility model relates to a kind of chalk and keeps in and pass out device by propping up, for classroom instruction, adopt this device environment that can not only make to give lessons to become clean and tidy, and accurately, swimmingly can get pen mouth by be transferred to from temporary storing bin by chalk, easy and simple to handle, belong to teaching aid technical field.
Background technology
Papery chalk holder is the packing box used in chalk storage, transport, is also the holding box during chalk uses.As chalk holding box, this papery chalk holder not only rapid wear, and also inconvenience is taken.In order to be substituted in the papery chalk holder generally used in the use of chalk, many replacement schemes are carried out.Such as, application number be 201320615834.4 a Chinese patent disclose the scheme that a kind of name is called " Pop-up chalk holder ".It comprises chalk holder main body, button, chalk outlet, fixed head, baffle plate, rotor plate, drawer and can open the door; Be connected with a drawer below chalk holder main body, right flank is connected with can open the door by axle, and chalk holder body interior is placed with chalk; Button comprises the button block be connected with spring and the bar be connected with rotor plate, and be wherein provided with the protruding block larger than button block diameter below button block, protruding block can block button, does not allow button eject chalk holder main body; The bar of button block lower end through the fixed block in chalk holder main body, and contacts with rotor plate; Chalk outlet is located at the right-hand member of the upper surface of chalk holder main body; The upper end of fixed head is connected to spring, and bar is through spring and spring is sandwiched in button block and fixed head; Baffle plate is irregularly shaped, and one end is fixed on chalk outlet place; Rotor plate is that certain angle of inclination is inner at chalk holder, and the end position of rotor plate near one end of chalk than close bar is low.During use, button press, the bar of the lower end of button drives one end of rotor plate to rotate, chalk is driven to move upward by rotor plate encounters the baffle plate of arc surfaced, by the effect of the baffle plate of arc surfaced and the common power of rotor plate, baffle plate along arc surfaced moves, and such chalk just can eject from chalk outlet.
Its deficiency of prior art is, the irregular difficulty of processing that causes of baffle shapes is large, and is difficult to ensure that in use procedure, plate shape does not change, and causes this chalk holder using state unstable; Mechanically, the ejection process of ejection operation and chalk lacks accuracy, and this chalk holder uses and seems not so freely, and the ejection of chalk also can not be so smooth and easy.
Utility model content
For the deficiencies in the prior art, the present invention is intended to design a kind of precise structure, easy and simple to handle, can smooth and easy transmission chalk and the chalk holder accurately put in place, for this reason, we have invented a kind of chalk temporary and by passing out device.
The chalk of the utility model is temporary and it is characterized in that by passing out device, and as shown in Figure 1 and Figure 2, temporary storing bin 1 is positioned at the top of described device, and in wedge shape bottom temporary storing bin 1, wedge shaped tip is that bar shaped is started to write mouth 2; Grooved roller 3 is positioned at below temporary storing bin 1, and some grooves 4 that contains are in grooved roller 3 circumference spaced at equal angles around, and as shown in Figure 3, be positioned on an axle head of grooved roller 3 by dynamic bevel gear 5, falling stop post plate 6 is positioned at grooved roller 3 side and the two geometry is coaxial; Parallel with mouth 2 of starting to write containing a groove 4, and, containing a groove 4, the opening shape of mouth 2 of starting to write and measure-alike, to rotate with grooved roller 3 containing a groove 4 and while the top of walking at any one, a groove 4 should be contained and be positioned at bar shaped and start to write below mouth 2; Hold a pawl 8 at the some U-lag shapes of the circumference spaced at equal angles around of pawl dish 7, hold a pawl 8 opening up, hold a pawl 8 and move towards identical with the circumference radial direction of pawl dish 7, drive bevel gear 9 is positioned at axle head on pawl dish 7, and worm gear 10 is positioned at pawl dish 7 lower shaft end; The quantity of holding a pawl 8 is identical with the quantity containing a groove 4, in an angle of pawl dish 7 circumference, one hold a pawl 8 be positioned at one to rotate with grooved roller 3 and bottom of walking containing below a groove 4, this holds a pawl 8 and should to contain a groove 4 parallel; Drive bevel gear 9 engages with by dynamic bevel gear 5, and gearratio is 1:1, as shown in Figure 4; Worm screw 11 is coaxial with the rotating shaft of servomotor 12; Worm screw 11 engages with worm gear 10, as shown in Figure 5.
Its technique effect of the utility model is, chalk is moved to temporary storing bin 1 from papery chalk holder, be on the grooved roller 3 of initial position one to be positioned at bar shaped containing a groove 4 and to start to write below mouth 2, piece of chalk 13 falls into and should contain a groove 4, and this chalk 13 stops other chalks in temporary storing bin 1 to fall into simultaneously.Servomotor 12 starts, driving claw dish 7 rotates an angle, this angle is two adjacent angle α holding a pawl 8 on pawl dish 7, as shown in Figure 6, drives grooved roller 3 to rotate an angle through pawl dish 7 rotating shaft simultaneously, this angle is at grooved roller 3 circumferentially two adjacent angle betas contained between a groove 4, as shown in Figure 7, because the quantity of holding a pawl 8 is identical with the quantity containing a groove 4, and be all angularly distribute on pawl dish 7, grooved roller 3 respectively, so angle α is equal with angle beta.Now, one empty starts to write below mouth 2 containing a groove 4 bar shaped of walking, and has again piece of chalk 13 to fall into this and contains a groove 4.Containing in the process moved down in the rotation with grooved roller 3 containing a groove 4 of chalk 13, falling stop post plate 6 auxiliary under, all the time chalk 13 is seized on both sides by the arms, until the falling stop scope shifting out falling stop post plate 6 moves to bottom, now, hold a pawl 8 for one and be positioned at this containing below a groove 4, chalk 13 drops on this under gravity and holds in a pawl 8.Under the control of the user of chalk, servomotor 12 discontinuous operation, pawl dish 7 is with angle α for angle of rotation intermittent rotary, and chalk 13 is finally accurately sent to out pen mouth 14, and user takes chalk 13 thus.In follow-up use in the same way, the chalk of temporary storing bin 1 by propping up ground, passing out from this device like clockwork, can realize goal of the invention.
The chalk of the utility model is kept in and simple by all parts structure of to pass out in device, regular shape, handling ease.
