Description
Technical field
This utility model relates to a kind of religion chi, specifically a kind of Multifunction teaching ruler.
Background technology
In curricula, math teacher needs to draw substantial amounts of figure on blackboard, and ruler of a great variety, the most not readily portable, simultaneously change ruler the most troublesome, some teacher for convenience, with regard to free hand drawing, the figure the most not only drawn is nonstandard, also allows student form the bad custom of free hand drawing simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of Multifunction teaching ruler, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of Multifunction teaching ruler, including chi bar, Magnet, angle index, pointer, chute, moving compasses head, fixing compasses head, slide block and chalk clamp；Described chi bar is divided into left and right two parts, left and right two parts to be connected by rotating shaft；The upper end on described chi bar surface is provided with length scale line；Described rotating shaft top is provided with pointer；Chi face around described pointer is provided with angle index；Described fixing compasses head is installed on the high order end of chi bar；Described moving compasses head is arranged in chute；Described moving compasses head is made up of slide block and chalk clamp；Described slide block is positioned at inside chute, non-dismountable, can only move left and right inside chute, and chute lower surface is provided with screwed hole；Described screwed hole is through hole；Described chalk clamp upper end is provided with nipple；Described chute is positioned on the downside of magnetic stripe, and the length of chute is equal to the length of chi bar；Described Magnet is arranged on the left end on chi bar surface；Described Magnet can adsorb the optional position at blackboard.
As further program of the utility model: described rotating shaft uses matched in clearance with chi bar left-half.
As further program of the utility model: described rotating shaft uses interference fits with chi bar right half part.
As further program of the utility model: described slide block and chalk clamp use threaded.
Compared with prior art, practical function of the present utility model is:
This utility model can draw or measure arbitrarily angled and straight line as required, ruler, protractor and set square is combined, and function is more various, and chi bar high order end is provided with Magnet simultaneously, can adsorb the optional position at blackboard, it is simple to teacher places and uses.
Accompanying drawing explanation
Fig. 1 is the structural representation of Multifunction teaching ruler.
Fig. 2 is the structural representation of moving compasses head in Multifunction teaching ruler.
Fig. 3 is Multifunction teaching ruler shaft part connection diagram.
In figure: 1-chi bar, 2-Magnet, 3-angle index, 4-pointer, 5-chute, 6-moving compasses head, 7-fixes compasses head, 8-slide block, 9-chalk clamp.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Referring to Fig. 1-3, a kind of Multifunction teaching ruler, including chi bar 1, Magnet 2, angle index 3, pointer 4, chute 5, moving compasses head 6, fixing compasses head 7, slide block 8 and chalk clamp 9；Described chi bar 1 is divided into left and right two parts, left and right two parts to be connected by rotating shaft；The upper end on described chi bar 1 surface is provided with length scale line；Described rotating shaft top is provided with pointer 4；Described rotating shaft uses matched in clearance with chi bar 1 left-half；Described rotating shaft uses interference fits with chi bar 1 right half part；Chi face around described pointer 4 is provided with angle index 3, and pointer 4 rotates with chi bar right half part；Described Magnet 2 is arranged on chi bar 1 high order end, and Magnet 2 can adsorb in blackboard optional position, facilitates teacher to use；Described fixing compasses head 7 is installed on the high order end of chi bar 1；Described chute 5 is provided with moving compasses head 6；Described moving compasses head 6 is made up of slide block 8 and chalk clamp 9；It is internal that described slide block 8 is positioned at chute 5, non-dismountable, can only move left and right, and chute 5 lower surface is provided with screwed hole inside chute 5；Described screwed hole is through hole；Described chalk clamp 9 upper end is provided with nipple；Described slide block 8 and chalk clamp 9 use threaded, and chalk clamp 9 can rotate always, until chalk clamp 9 top contacts bottom chute 5, are used for fixing moving compasses head 6.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art is possessed, it is also possible to make a variety of changes on the premise of without departing from this patent objective.
