Abstract
The utility model provides a distance adjusting type grid line describing device and belongs to the technical field of teaching aids. The distance adjusting type grid line describing device structurally comprises two long handle describing device casing pipes and two short handle describing device casing pipes, wherein a long handle telescopic spring and a long handle chalk beam tube are connected to the interior of each long handle describing device casing pipe in a sleeved manner, one end of the long handle telescopic spring is connected with the blind end inside the long handle describing device casing pipe while the other end of the long handle telescopic spring is connected with the top of the long handle chalk beam tube, and a piece of chalk is arranged inside the long handle chalk beam tube; a short handle telescopic spring and a short handle chalk beam tube are connected to the interior of each short handle describing device casing pipe in a sleeved manner, and a piece of chalk is arranged inside the short handle chalk beam tube; and the tops of the long handle describing device casing pipes are hinged with those of the two short handle describing device casing pipes through a link bolt, and a lock nut is arranged on the link bolt. In the utility model, distance adjustments at the pen ends of the describing device can be achieved by adjusting the opening angles of the four describing pens of the describing device, four pen contacts are enabled to completely compress a blackboard through the buffering of the springs so as to describe grid lines directly at one step, repeated actions are not required, and the operation is simple and convenient.
Description
Technical field
The utility model relates to the teaching aid technical field, specifically a kind of spacing adjustable type ruling divider calipers.
Background technology
General; in the teaching of Middle School English; the teacher need state the teaching of English aspect coming the student write at the blackboard upper plate through regular meeting; often on blackboard, draw three rulings as required earlier; the teacher adopts set square or the setting-out on blackboard of long chi more, and through the setting-out of regular meeting's repetitive operation, this has strengthened teacher's labour intensity to a certain extent; increased unnecessary instructional blocks of time, brought to a certain extent negative effect to teaching.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of spacing adjustable type ruling divider calipers is provided.
The technical solution of the utility model realizes in the following manner, this spacing adjustable type ruling divider calipers, its structure comprises two long handle divider calipers sleeve pipes and two short handle divider calipers sleeve pipes, be socketed with long handle coil tension spring and long handle chalk beam tube in the long handle divider calipers sleeve pipe, long handle coil tension spring one end is connected with cecum in the long handle divider calipers sleeve pipe, the other end is connected with long handle chalk beam tube top, is provided with chalk in the long handle chalk beam tube; Be socketed with short handle coil tension spring and short handle chalk beam tube in the short handle divider calipers sleeve pipe, be provided with chalk in the short handle chalk beam tube; Two long handle divider calipers sleeve pipes and two short handle divider calipers cannula tip are hinged by a link bolt, and link bolt is provided with locking nut.
Two long handle divider calipers sleeve pipes are separately positioned on two left and right sides of facing short handle divider calipers sleeve pipe mutually.
The beneficial effect that the utility model is compared with prior art produced is:
This spacing adjustable type ruling divider calipers adopts four divider calipers, wherein two long, two weak points in addition, symmetric arrays setting, the top is hinged jointly, adjusting by opening angle between four divider calipers can realize that the spacing of the divider calipers tip of the brushstyle of a writing or painting regulates, and treats that spacing regulates back locking locking nut, and the buffering by spring makes four style of writing points all by being pressed on the blackboard, directly setting-out, disposable finishing need not repeatedly to repeat, and be simple and convenient.This spacing adjustable type ruling divider calipers also can be used as compasses to be used, and it is reasonable in design, simple in structure, use is easy to carry, be easy to dismounting and maintenance, has good value for applications.
