Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Embodiment 1
A kind of different colours chalk is distinguished automatic spring device as shown in Figure 1, comprise ejector body 1, on described ejector body 1, offer respectively the first chalk outlet 2, the second chalk outlet 3, on described ejector body 1, be separately installed with chalk and release button, chalk SR.In described ejector body 1, be separately installed with the first tooth bar push pedal 4, the second tooth bar push pedal 5, the 3rd tooth bar push pedal 6, the 4th tooth bar push pedal 7, reset push pedal 12, wherein said the first tooth bar push pedal 4 is connected with the second tooth bar push pedal 5 engagements by the first gear 8, described the second tooth bar push pedal 5 is connected with the 3rd tooth bar push pedal 6 by contiguous block 16, and described the 3rd tooth bar push pedal 6 is connected with the 4th tooth bar push pedal 7 engagements by the second gear 9.Described the 3rd tooth bar push pedal 6 forms with contiguous block 16 is integrally manufactured.In described reset push pedal 12, reseting plate 13 is installed, and between described reseting plate 13 and reset push pedal 12, back-moving spring 14 is installed; In described the 3rd tooth bar push pedal 6, the first chalk push pedal 11 is installed, in described the 4th tooth bar push pedal 7, the second chalk push pedal 10 is installed.On described ejector body 1, offer respectively the first chalk installing port 15, the second chalk installing port 25.
Described chalk is released button and is comprised chalk outer pushing plate 17, chalk inner pushing plate 18, described chalk outer pushing plate 17 is connected with chalk inner pushing plate 18 by head rod 19, described chalk inner pushing plate 18 is connected with the first tooth bar push pedal 4, and the first spring 20 is installed on the head rod 19 between described chalk outer pushing plate 17 and ejector body 1; Described chalk SR comprises reset outer pushing plate 21, reset inner pushing plate 22, described reset outer pushing plate 21 is connected with reset inner pushing plate 22 by the second connecting rod 23, described reset inner pushing plate 22 is connected with reset push pedal 12, on the second connecting rod 23 between described reset outer pushing plate 21 and ejector body 1, the second spring 24 is installed.
A kind of different colours chalk described in the present embodiment respectively automatic spring device in use, is first first pressed chalk and is released button, promotes the first tooth bar push pedal 4 move right by chalk inner pushing plate 18.The first tooth bar push pedal 4 drives the second tooth bar push pedal 5 to be moved to the left by the first gear 8.The second tooth bar push pedal 5 drives contiguous block 16 to be moved to the left when being moved to the left, and contiguous block 16 drives the 3rd tooth bar push pedal 6 to be moved to the left.The 3rd tooth bar push pedal 6 moves right the 4th tooth bar push pedal 7 by the second gear 9.The first chalk push pedal 11 can be released white chalk for use from the first chalk outlet 2.The second chalk push pedal 10 can be released pastel for use from the second chalk outlet 3.When not needing to use chalk, press chalk SR, reset inner pushing plate 22 promotes reset push pedal 12 and moves right, the push pedal 12 that simultaneously resets drives reseting plate 13 to move right, while moving with the first tooth bar push pedal 4 phase screens on the top of reseting plate 13, reseting plate 13 is owing to being subject to the elastic force of back-moving spring 14 and the downforce of the first tooth bar push pedal 4, make 13 pairs of the first tooth bar push pedal 4 effect downforce of reseting plate, thereby make the positioner of the first tooth bar push pedal 4 disengagings and the first gear 8, utilize the first spring 19 and the second spring 24 respectively the first tooth bar push pedal 4 and reset push pedal 12 to be reached the effect of reset simultaneously.Thereby the reset of the first tooth bar push pedal 4 drives the reset of the second tooth bar push pedal 5, the 3rd tooth bar push pedal 6, the 4th tooth bar push pedal 7.Because the first chalk push pedal 11 and the second chalk push pedal 10 are installed with chalk screens, thereby therefore the first chalk push pedal 11 and the second chalk push pedal 10 reset chalk are sprung back in ejector body 1.
A kind of different colours chalk of the present embodiment is automatic spring device respectively, the first chalk outlet of offering can automatic spring white chalk, the second chalk outlet of offering is automatic spring pastel simultaneously, be convenient to taking and managing of different colours chalk, improved the utilization rate of resource, effectively improved quality of instruction, and moistureproof and waterproof.
