Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, 2, 3, the blackboard four line lattice scriber used in the English teaching described by the present embodiment, comprise pedestal 1 and four chalk holders 2 be positioned on pedestal 1, described pedestal 1 top is handle 3; Described chalk holder 2 is made up of body 4 and lid 5, lid 5 and body 4 top are formed and removably connect, here said removably connecting can be clamping, also can be spirally connected, described lid 5 center is provided with screw, be threaded connection screw rod 6 in described screw, described screw rod 6 front end has a disk 7; Be provided with chalk fixed block 8 in described body 4, have the annular protrusion 9 for fixing chalk 16 bottom this chalk fixed block 8, its top has depression 10, and described disk 7 is positioned at this depression 10, and described chalk fixed block 8 top is fixedly connected with limited block 11; There is bottom described body 4 mouth of pipe section 12 entered to convex, a spring-backed quill 13 is provided with inside mouth of pipe section 12, this spring-backed quill 13 top has flange 14, and described flange 14 is located on the end face of described mouth of pipe section 12, is provided with spring 15 between flange 14 and chalk fixed block 8.
This blackboard four line lattice scriber, chalk 16 is contained in chalk holder 2, chalk 16 top is fixed in the annular protrusion 9 of chalk fixed block 8, chalk fixed block 8 is propped up by spring 15, and chalk fixed block 8 top is firmly withstood by screw rod 6, like this in scratching process, chalk 16 would not bounce back, and can rule normally; After chalk uses a period of time to have consumption, turn screw rod 6 downwards, chalk fixed block 8 can be ejected downwards, guarantee its requirement of ruling normally; Disk 7 bottom screw rod 6 is fixed between chalk fixed block 8 and limited block 11, can hold disk 7 because chalk fixed block 8 top is provided with depression 10, and time such screw rod 6 rotates, chalk fixed block 8 is motionless, guarantees that chalk is stablized; There is bottom body 4 mouth of pipe section 12 entered to convex, mouth of pipe section 12 pairs of chalks have fixation, it can effectively prevent chalk from fractureing, spring-backed quill 13 effectively can eliminate the gap between chalk 16 and mouth of pipe section 12, and slowly walk downward along with chalk, spring-backed quill 13 can swell along with the increase of chalk 16 bore, guarantees that chalk can normally be stretched; Spring 15 also has fixation to spring-backed quill 13 in addition.
In the present embodiment, spring-backed quill 13 can adopt elastic caoutchouc.
This blackboard four line lattice scriber, chalk can be contained in chalk holder, and teacher can utilize this device on blackboard, mark four line lattice easily, effectively can improve efficiency of teaching, be particularly suitable for traditional black board teaching.
