Abstract
The utility model relates to a demonstrator for three direction views, which is suitable for mechanical drawing teaching. The utility model is characterized in that the space of the demonstrator for three direction views is provided with a supporting frame which is an integral or combined curved fine rigid material bar whose one end is fixed on the demonstrator of the main view or the left view and the other end can support or hold light stereo models. The utility model has the advantages of no slipping, convenience for operation and lecture for teachers and favorable teaching effect.
Description
A kind of three-view diagram demonstration board belongs to teaching aid, is applicable in the mechanical drawing teaching and uses.Present three-view diagram demonstration board, the fixing bracing frame of middle nothing, in teaching, the teacher often takes demonstration board on the other hand, and the another hand rest is lived model, can't give the student at the projection characteristics like this and give directions.Particularly, when demonstration graph was launched, model can not be stayed on the preceding space of plate, can not do further demonstration explanation for the student, was unfavorable for that the student understands the projection law of three-view diagram.
The purpose of this utility model is, overcome and go up art model demonstration plate shortcoming, demonstration board in a kind of space that the stereoscopic model such as the foamed plastic model of lightweight can be fixed on the encirclement of three-view diagram plate is provided, is convenient to explaining illustration projection law, reach good teaching purpose.
The technical solution of the utility model is: this three-view diagram demonstration board, include three-view diagram plate 1, left view plate 6, with overlook chart board 14, in the space that the three-view diagram plate is surrounded, the bracing frame that the stereoscopic model that can support lightweight foamed plastics is arranged, this bracing frame main component is by combination, can be two poles 8,10 combine by cross bore fixed cover 9, or form by a thin rigid material pole 8 ' bending of integral body, one end and front view plate 1, or left view plate 6 is by fixture 2 or 2 ' connection, the other end points to overlooks chart board 14, have on it can clamping the carriage 15 of stereoscopic model, or/and clamper 12, or/and have on the carriage 15 and the corresponding clip magnet 16 of iron sheet on the model.
Described three-view diagram demonstration board, its main component pole 8,10, or thin rigid material pole 8 ', can be Metallic rod or reinforced plastics bar with rigidity; Metallic rod can be that diameter is 2 millimeters to 5 millimeters a steel wire; With combination or whole pole 8,10, or 8 ', be fixed on the front view plate or overlook fixture 2 on the chart board, can be the clips that have the spring fixedly metal of pole 10 or plastics on it, or at the front view plate or overlook "T"-shaped 2 of sliding in the "T"-shaped groove in chart board top '; The clamper 12 of pole 8 bottoms connects with pole 8 by fixed cover 11; The magnetic patch of installing on the carriage 15 16 is permanent magnets.Carriage 15 can be the lower end that is welded on pole 8, or fixes with nut by the screw thread of pole 8 lower ends, or carriage can slide on pole 8 and pass through screw 17 location with fixing.
In conjunction with the accompanying drawings this reality is made novel organization plan and user mode is described further:
Fig. 1, three-view diagram demonstration board structural representation;
Fig. 2, integral post 8 ' pass through screw 17 joining embodiment with fixture 2 and carriage 15.
Fig. 3, "T"-shaped 2 ' with pole 10 and 8 ' joining embodiment.
Fig. 4, carriage 15 and pole 8 lower ends thread connection embodiment.
Fig. 5, pole 10 or 8 ' by fixture 2 ' and screw 3 ' fixing embodiment.
Among the figure: 1, front view plate, 2, fixture, 3, hold-down nut, 4, the loose joint butt axle, 5, loose-leaf, 6, the left view plate, 7, screw.8, pole, 9, the cross bore fixed cover, 10, pole, 11, fixed cover, 11 ', screw, 12, holding frame, 13, the loose joint butt axle, 14, overlook chart board, 15, carriage, 16, magnet, 17, screw, 3 ', screw, "T"-shaped of 2 ' fixture.
Fig. 1 is one of embodiment of the present utility model, and the main component of bracing frame is by pole 8,10 combinations.Pole the 8, the 10th, the bicycle quick steel wire.During use, earlier that an end is fixing with fixture 2 with pole 8 by nut 3.Fixture 2 is common iron clamp, and the suitable locus that carriage 15 is parked is by the screw on the cross fixed cover 97 and 7 ' location.Model is placed on the carriage 15, if iron sheet is arranged at model bottom, then clamping equipment 12 can, also can clamp downwards and fixing by clamper 12.
Fig. 2 be integral post 8 ' with fixture 2 and carriage 15 by screw 17 joining embodiment, the carriage 15 of this embodiment position in the three-view diagram board space, by nut 3 and screw 17 location, for the cantilever pole that makes bracing frame partly is unlikely sagging, pole point to overlook chart board 14 an end can with overlook chart board 14 and contact.
Fig. 3, for use "T"-shaped 2 ' replace the embodiment of fixture 2.
Fig. 4, be carriage 15 and the embodiment of support 8 lower ends with thread connection, this kind structure can directly be utilized the screw thread of bicycle wire one end.
Polyfoam stereoscopic model among the embodiment is that polystyrene plastics is made.Advantage of the present utility model is, the teacher is when the explanation three-view diagram, because model is clamped in the three-view diagram board space, therefore can a hand-held chart board, and another points point model, has made things convenient for speech.Simultaneously, if the hinge axis on the three-view diagram plate 13 is taken out, the three-view diagram plate becomes a plane, and at this moment, model still in original space, makes the student observe easily, experience, and reaches good teaching purpose.
