Abstract

The utility model provides a rotating wheel-type chalk holder. Chalks with required colors can be popped out by pressing the rotating wheel-type chalk holder with hands. The rotating wheel-type chalk holder is divided into a front cavity and a rear cavity, wherein a rotating wheel and a ratchet wheel are placed in the front cavity, and a rotating and popping mechanism is arranged in the rear cavity. When a button is pressed down, angle blocking plates rotate, and an ejector pin pushes the ratchet wheel, so that the rotating wheel rotates by a certain angle; the ejector pin is matched with a small rotating wheel so as to ensure that a corresponding driving hammer beats a firing pin, and the other end of the rotating wheel is in an idling condition, thus the purpose of only popping out white chalks or colored chalks is achieved. The rotating wheel-type chalk holder is simple to operate and difficult to damage, saves space, can be suspended on a wall and is particularly suitable for teaching.

Description

Runner Pop-up chalk holder

Technical field:

The utility model relate to a kind of can hand by the rotary-type chalk holder that ejects chalk, especially can eject respectively white and colored two kinds of chalks.

Background technology:

At present, known chalk holder is all the square box of papery, instant packed with transport, but there is following shortcoming in existing product: when (1) is used for the first time, because chalk is arranged and is closely not easy to take out; (2) papery chalk holder is used last easily damage, and while taking, easily allowing chalk shed affects lectern health; (3) existing chalk holder requires white and pastel will distinguish dress, function singleness; (4) with surplus chalk end, there is no retracting device, affect environmental sanitation.

Summary of the invention:

In order to overcome existing chalk holder cracky, should not take, function singleness, the unrenewable problem of chalk end, the utility model provides a kind of runner Pop-up chalk holder, has solved the problem in prior art.

The utility model solves the technical scheme that its technical problem adopts: chalk holder consists of iron sheet, is divided into two cavitys in box, and ante-chamber is placed runner and is used for holding white and pastel; In back cavity, place rotation, ejecting mechanism.While pressing any one in white or color button, by connecting rod, little runner, axle, thimble and ratchet, all can realize the angular turn of determining of runner, then by the cooperation of corresponding hammer, striker, reach the object that ejects required color chalk.And with after chalk end can directly render in the recovery drawer of back cavity, be convenient to centralized recovery and process.

The beneficial effects of the utility model are, this runner Pop-up chalk holder has replaced the papery chalk holder of easy breakage, difficulty while having avoided taking chalk first, can eject respectively white and colored chalk, and can collect the chalk end after using, can also hang on wall, save space, simple to operate, hygienic environment-protecting.

The specific embodiment

Below in conjunction with the most preferred embodiment shown in accompanying drawing, be described in further detail

While pressing the white chalk button 2 on casing 11, can drive the connecting rod II38 of back to promote II39 rotation, take over a business II39 when promotion is put after the hammer II28 of axle I18 rotation, also can drive little runner II40 and axle II19 to rotate, axle II19 now with respect to little runner I42 in idling conditions, axle II19 can not drive little runner I42 to rotate, so hammer I20 does not put after the meeting, pastel just can not eject yet.The rotation of axle II19 also can make angle control lever 41 that angle block board 44 is exited from locating groove 15 the insides, now, axle II19 starts to order about thimble and 31 rotates in flakes, thereby make thimble 30 head on ratchet 17 and rotate corresponding angle, because have square boss on ratchet 17, and by centre bore 14 and runner 6 location, so runner 6 also can turn over corresponding angle, and when thimble 30 rises to certain position, the angle control lever 41 angle block board 44 that nuzzles up rebounds it again, angle block board 44 starts to contact runner 6, now, angle screens spring 33 is always in compressive state, when thimble 30 rise to rise from time, angle block board 44 snaps in locating groove 15, runner 6 blocks motionless, white chalk standing groove 12 is aimed at white chalk ejection hole 4 and white chalk impingement holes 16, meanwhile, after hammer II28, pendulum arrives maximum distance, the spring II29 that two ends are fixed on axle III22 and hammer II28 is stretched.When white button spring 37 is rebounded white chalk button 2, owing to taking over a business II39, no longer act on little runner II40 and axle II19, be subject to 32 effects of thimble spring, thimble 30 can return to home position, simultaneously, angle control lever 41 presses down after certain angle the spring hinge 45 on angle block board 44, angle control lever 41 is got back to below angle block board 44 again, now, spring II29 drives hammer II28 to clash into striker II27, striker II27 ejects hole 4 by white chalk from white chalk and ejects, be subject to the spring IV34 effect in spring card slot II26, striker II27 and hammer II28 return to its home position.

While pressing the pastel button 1 on casing 11, can drive the connecting rod I35 of back to promote I43 rotation, take over a business I43 when promotion is put after the hammer I20 of axle I18 rotation, also can drive little runner I42 and axle II19 to rotate, axle II19 now with respect to little runner II40 in idling conditions, axle II19 can not drive little runner II40, so hammer II28 does not put after the meeting, white chalk just can not eject yet.The rotation of axle II19 can make angle control lever 41 that angle block board 44 is exited from locating groove 15 the insides, now, axle II19 starts to order about thimble and 31 rotates in flakes, thereby make thimble 30 head on ratchet 17 and rotate corresponding angle, when thimble 30 rises to certain position, the angle control lever 41 angle block board 44 that nuzzles up rebounds it again, angle block board 44 starts to contact runner 6, now, angle screens spring 33 is always in compressive state, when thimble 30 rise to rise from time, angle block board 44 snaps in locating groove 15, making pastel standing groove 13 and pastel eject hole 3 aims at, meanwhile, after hammer I20, pendulum arrives maximum distance, the spring I21 that two ends are fixed on axle III22 and hammer I20 is stretched.When color button spring 36 rebounds pastel button 1, owing to taking over a business I43, no longer act on little runner I42 and axle II19, be subject to 32 effects of thimble spring, thimble 30 can return to home position, simultaneously, angle control lever 41 presses down after certain angle the spring hinge 45 on angle block board 44, angle control lever 41 is got back to below angle block board 44 again, now, spring I21 drives hammer I20 to clash into striker I23, striker I23 ejects hole 3 by pastel from pastel and ejects, be subject to the spring III25 effect in spring card slot I24, striker I23 and hammer I20 return to its home position.

After white chalk or pastel are finished, the magnet contactor 7 that can open on case lid 5 is loaded required chalk; With the chalk of half, can be placed on half chalk jack 8 the insides temporarily, facilitate take next time; With remaining chalk end, can put into chalk end from chalk end feeder 9 and collect drawer 10 the insides, convenient recovery, protection of the environment.
