Abstract
The utility model provides a parallel marking device, belonging to a mathematical teaching aid. The structure of the device comprises a supporting chassis, a left support frame and a right support frame, wherein the upper end of the left support frame is vertically connected with the left end of the supporting chassis; the upper end of the right support frame is vertically connected with the right end of the supporting chassis; and the left support frame and the right support frame are respectively provided with a guide way. The parallel marking device is characterized in that a sliding frame is arranged between the left support frame and the right support frame; the left end of the sliding frame penetrates in the left support frame and is articulated with the guide way of the left support frame; the right end of the sliding frame penetrates in the right support frame and is connected with the right support frame through a locking button; a slider is arranged on the sliding frame in a penetrating manner, and a pen holding hole is arranged in the middle of the slider; and the pen holding hole corresponds to a strip through hole arranged in the middle of the sliding frame. Compared with the prior art, the device has the characteristics of reasonable design, simple structure, convenience in use, accurate drafting, higher teaching efficiency and the like.
Description
Technical field
The utility model relates to a kind of mathematical education apparatus, specifically a kind of parallel scribing device.
Background technology
On the present mathematical education class, need teacher to draw parallel lines on the blackboard of being everlasting, normal conditions are with two set squares, by wherein one set square slided on another set square drawing; This situation is drawn comparatively loaded down with trivial details, and the parallel lines of drawing are accurate inadequately, also can't carry out the distance location, thereby reduce efficiency of teaching.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of parallel scribing device reasonable in design, simple in structure is provided.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the support underframe, left side bracing frame and right bracing frame, bracing frame upper end, a left side and vertical being connected of left end of supporting underframe, right bracing frame upper end and vertical being connected of right-hand member of supporting underframe, be respectively arranged with the guiding road on left side bracing frame and the right bracing frame, be provided with travelling carriage between left side bracing frame and the right bracing frame, the travelling carriage left end penetrates in the left bracing frame and with its guiding road and is hinged, the travelling carriage right-hand member penetrates in the right bracing frame and by the locking button and is connected with right bracing frame, be installed with slider on the travelling carriage, the slider middle part is provided with pen plughole, and pen plughole is corresponding with the strip through-hole that the travelling carriage middle part is provided with.
Right bracing frame is provided with scale.
The length of strip through-hole is identical with distance between left bracing frame, the right bracing frame.
Be slidingly connected between slider and the travelling carriage, be slidingly connected between travelling carriage and left bracing frame, the right bracing frame.
Pen plughole is corresponding with the position of locking button.
During use, the rotational lock button is adjusted travelling carriage position up and down, by the unusual accurate in locating of the scale on the right bracing frame.Behind the location, the rotational lock knob with the fixed-site of travelling carriage, inserts in the pen plughole with chalk then again, drives the slider line and gets final product; Can guarantee the degree of accuracy of ruling by scriber.
A kind of parallel scribing device of the present utility model compared with prior art, the beneficial effect that is produced is:
1, operation is comparatively simple, has made things convenient for teacher to draw parallel lines, has reduced teacher's labour intensity.
2, the parallel lines of Hui Zhiing are comparatively accurate, can help the better learning teaching content of student, improved efficiency of teaching.
3, have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, thereby have excellent popularization and use prospect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, support underframe, 2, right bracing frame, 3, the guiding road, 4, the locking button, 5, scale, 6, travelling carriage, 7, strip through-hole, 8, slider, 9, pen plughole, 10, left bracing frame.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description the in detail.
As shown in drawings, a kind of parallel scribing device of the present utility model, its structure comprises support underframe 1, left side bracing frame 10 and right bracing frame 2, bracing frame 10 upper ends, a left side and vertical being connected of left end of supporting underframe 1, right bracing frame 2 upper ends and vertical being connected of right-hand member of supporting underframe 1, be respectively arranged with guiding road 3 on left side bracing frame 10 and the right bracing frame 2, be provided with travelling carriage 6 between left side bracing frame 10 and the right bracing frame 2, travelling carriage 6 left ends penetrate in the left bracing frame 10 and with its guiding road 3 and are hinged, travelling carriage 6 right-hand members penetrate in the right bracing frame 2 and by locking button 4 and are connected with right bracing frame 2, be installed with slider 8 on the travelling carriage 6, slider 8 middle parts are provided with pen plughole 9, and pen plughole 9 is corresponding with the strip through-hole 7 that travelling carriage 6 middle parts are provided with.
The length of strip through-hole 7 is identical with distance between left bracing frame 10, the right bracing frame 2.
Be slidingly connected between slider 8 and the travelling carriage 6, be slidingly connected between travelling carriage 6 and left bracing frame 10, the right bracing frame 2.
A kind of its processing and fabricating of parallel scribing device of the present utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be those skilled in the art's known technology.
