Description
Technical field
the utility model relates to engineering graphics teaching field, relates in particular to a kind of for the chart board on engineering graphics teaching.
Background technology
graphing of Engineering is a profession basis subject, taking the Theory of Projections of descriptive geometry as basis, and taking ruler, compasses, chart board as instrument, taking blackboard, wooden model, wall chart as medium, the history of existing more than 200 year.Mechanical engineering drawing is the elementary course that embodies industry science feature, is also one of the professional basic course that must learn of Engineering Students.It has brought into play important effect cultivation student as all many-sides such as space imagination and ideation and promotion process of industrialization on creative thinking basis.Engineering drawing is requisite technological document in producing, at world wide general " language of engineering ".The drafting of correct specification and reading engineering drawing are the basic qualities of engineers and technicians' indispensability.But, on engineering graphics teaching chart board on existing market, lack the device that not only contributes to increase the bearing capacity of body but also contribute to the weight that alleviates body, on some engineering graphics teaching chart board, lack and contribute to device that soft board is packed up, this is unfavorable for keeping the fineness of soft board, also be unfavorable for the fixing of drawing, on the engineering graphics teaching chart board also having, lack the stationary device that contributes to soft board, can not meet the demand of engineering graphics teaching.
Utility model content
the purpose of this utility model is in order to overcome the deficiencies in the prior art, provides a kind of for the chart board on engineering graphics teaching.
the utility model is to be achieved through the following technical solutions:
a kind of for the chart board on engineering graphics teaching, also comprise body, in described body, be provided with cavity, on described cavity, supporting screw is installed, the right-hand member of described cavity is provided with reel, on described reel, is wound with soft board, the both sides of body are provided with pressing plate first, the end of described pressing plate first is provided with conical pressure head, and described conical pressure head is provided with projection, and a side of body is also provided with pressing plate second.
as optimal technical scheme of the present utility model, one end of described reel is provided with rotating handles, described body be shaped as rectangle.
as optimal technical scheme of the present utility model, described supporting screw has two at least, and is uniformly distributed and is arranged on cavity.
as optimal technical scheme of the present utility model, described pressing plate first has four, and the symmetrical both sides that are arranged on body.
as optimal technical scheme of the present utility model, described pressing plate second has two, and a symmetrical side that is arranged on body.
when on-the-spot use, user will compress soft board by pressurization first, then by pressing plate second, drawing will be pressed on soft board, four angles of drawing are fixed by adhesive tape, can carry out engineering drawing work.
compared with prior art, the beneficial effects of the utility model are: the utility model contributes to increase the bearing capacity of body on the one hand by being provided with the cavity of supporting screw, contribute on the other hand to alleviate the weight of body, contribute to soft board to pack up by being provided with the reel of soft board, keep the fineness of soft board, also contribute to the fixing of drawing, contribute to the fixing of soft board by being provided with the pressing plate first of projection, and simple in structure, easy to operate, economical and practical.
