Description
Technical field
The utility model relates to a kind of Multifunctional meal card cutting ferrule.
Background technology
Mess card is prevailing in middle school and university, is middle school student and undergraduate campus necessity, and student, except utilizing mess card to buy in campus food, many times also can utilize one side setting-out of mess card.In order to alleviate the wearing and tearing of mess card and dirt, someone has designed a kind of mess card cutting ferrule, on one side cutting ferrule is carved with scale, to play the effect of ruler; Another side is provided with protractor, and then measures angle.Yet because cutting ferrule thickness is larger, so one side carving graduatedly while measuring length with cutting ferrule, can make to measure inaccuracy due to the reason of thickness.And use amount hornwork is when take measurement of an angle, and mess card must be taken out, not only measurement result inaccuracy, operates also very loaded down with trivial details.In addition, because the scale for measuring is positioned at cutting ferrule outside, be easy to thicken unclear because of wearing and tearing.So this cutting ferrule does not have practicality.This cutting ferrule function is also more single simultaneously, lacks other additional function.
Utility model content
For the deficiency existing in prior art, in order to overcome the existing complex steps while measuring that is fastened in, result inaccuracy, additional function is few, the scale shortcoming easy to wear on cutting ferrule simultaneously, the utility model provides a kind of Multifunctional meal card cutting ferrule of new structure.
In order to reach above object, the utility model is to realize by the following technical solutions:
A kind of Multifunctional meal card cutting ferrule, comprise a rectangular-shaped plastic casing (1), the side at described plastic casing (1) minor face place is provided with the draw-in groove (2) for mess card is installed, curriculum schedule (3) is posted on the surface of described plastic casing (1), and the side of described plastic casing (1) is connected with a transparent plastic sheet (7); The front end of described transparent plastic sheet (7) arranges a buckle (4), the upper position corresponding with buckle (4) of described plastic casing (1) arranges a boss (11), and described buckle (4) and boss (11) are for the folding between transparent plastic sheet (7) and plastic casing (1); On described transparent plastic sheet (7), there is an inversion trapezoidal (10), there is a protractor (8) its inside, the straight flange of protractor (8) overlaps with the upper base of being inverted trapezoidal (10) and is isometric, and the non-coincidence part of trapezoidal by being inverted (10) and protractor (8) hollows out; Be provided with scale (9) being inverted on the going to the bottom of trapezoidal (10), after transparent plastic sheet (7) buckle is fixing, the scale of being inverted scale (9) on the going to the bottom of trapezoidal (10) and protractor (8) is all positioned at the inner side of transparent plastic sheet (7).
A long limit of the bottom surface of above-mentioned plastic casing (1) is as the first turn-line (5), a long limit of connected transparent plastic sheet (7) is as the second turn-line (6), and the distance between described the first turn-line (5) and the second turn-line (6) equals the thickness of rectangle plastics housing (1).
Two base angles of above-mentioned inversion trapezoidal (10) are respectively 60 ° and 45 °.
The utility model compared with prior art useful effect is:
1, because the thickness of transparent plastic sheet and the thickness of common ruler approach, so when the scale on utilizing plastic sheet is measured length, avoided the measurement result inaccuracy causing because of thickness;
2, when taking measurement of an angle, only transparent plastic sheet tiling can need be measured, do not need mess card to take out.Simple to operate, and measurement result is more accurate;
3,, after transparent plastic sheet is fastened, its high scale is to be all positioned at plastic sheet inner side, has avoided scale directly and foreign object contact wear, has extended the service life of scale;
4, the measuring appliance on transparent plastic sheet concentrates on a place, compares with disperseing distribution and more saves space, is also easier to processing, easy operating;
5, on this mess card cutting ferrule with curriculum schedule, avoided separately carrying to the taking of space, make student more convenient for the inquiry of school timetable simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front schematic view of plastic sheet while separating with plastic casing;
Fig. 3 is the side view of Fig. 2.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Multifunctional meal card cutting ferrule, comprise a rectangular-shaped plastic casing 1, the side at described plastic casing 1 minor face place is provided with for the draw-in groove 2 of mess card is installed, curriculum schedule 3 is posted on the surface of described plastic casing 1, and the side of described plastic casing 1 is connected with a transparent plastic sheet 7; The front end of described transparent plastic sheet 7 arranges a buckle 4, and on described plastic casing 1, the position corresponding with buckle 4 arranges a boss 11, and described buckle 4 and boss 11 are for the folding between transparent plastic sheet 7 and plastic casing 1; On described transparent plastic sheet 7, have one to be inverted trapezoidally 10, there is a protractor 8 its inside, and the straight flange of protractor 8 overlaps with the upper base of being inverted trapezoidal 10 and be isometric, and the non-coincidence part of inversion trapezoidal 10 and protractor 8 is hollowed out; Be provided with scale 9 being inverted on trapezoidal 10 go to the bottom, after transparent plastic sheet 7 buckles are fixing, the scale of being inverted scale 9 on trapezoidal 10 go to the bottom and protractor 8 is all positioned at the inner side of transparent plastic sheet 7.
A long limit of the bottom surface of above-mentioned plastic casing 1 is as the first turn-line 5, and a long limit of connected transparent plastic sheet 7 is as the second turn-line 6, and the distance between described the first turn-line 5 and the second turn-line 6 equals the thickness of rectangle plastics housing 1.
Two base angles of above-mentioned inversion trapezoidal 10 are respectively 60 ° and 45 °.
Mess card is put into cutting ferrule along the draw-in groove 2 of the side at plastic casing 1 minor face place, during measuring appliance on need to using transparent plastic sheet 7, boss 11 separation by the buckle 4 of transparent plastic sheet 7 front ends from plastic casing 1, utilize the first turn-line 5 and the second turn-line 6 to adjust transparent plastic sheet 7, make above-mentioned transparent plastic sheet 7 lie in desktop: utilization hornwork 8 can take measurement of an angle, the scale (9) of utilize being inverted on trapezoidal 10 go to the bottom can be measured length, utilize to be inverted the special angle that two base angles of trapezoidal 10 can draw 45 ° and 60 °, and then realize the function of set square.Now can also directly browse the curriculum schedule 3 on plastic casing 1 end face.After finishing using, the buckle 4 of transparent plastic sheet 7 front ends is fastened to again to the boss 11 of plastic casing 1, now the first turn-line 5 and the second turn-line 6 overlap with two seamed edges of plastic casing 1 respectively, and the scale of being inverted trapezoidal 10 scales 9 on going to the bottom and protractor 8 is all positioned at the inner side of transparent plastic sheet 7.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
