Description

A kind of self-closing writing case

Technical field:

The utility model relates to a kind of writing case, more specifically to a kind of self-closing writing case.

Background technology:

The writing case student is used for filling the box of the stationery such as pen, pencil, ruler, rubber.Quality is a lot, and wooden, irony, plastic products are generally arranged, and is different, mostly is rectangular shape.Writing case is one of indispensable instrument of student; the pupil usually can be because of carelessness; and pencil box is overturned; the stationery of pencil, ball pen, rubber, ruler of the inside and so on the ground that will be scattered; the nib of pencil might be broken, and the nib of ball pen might be broken, and where rubber has not all known if might rolling; just can address this problem if can design a kind of stationery that prevents that stationery drops out in the box, be very useful so design a kind of self-closing writing case.

The utility model content:

The purpose of this utility model is exactly for the deficiencies in the prior art, and a kind of self-closing writing case is provided.The utlity model has simple in structurely, it is convenient to open, as long as once can automatically opening by elastic button, convenient and practical; Under the cover closing state, sound construction between lid and the base, the advantage that the objects such as its inner pencil can not drop out.

Technology solution of the present utility model is as follows:

A kind of self-closing writing case comprises writing case base, semicircle spring and writing case lid, and the edge of described writing case base is provided with an elastic locking device; One end of semicircle spring is fixed on writing case base bottom, and an other end is fixed on the writing case lid.

Described elastic locking device comprises elastic button, spring, dop and through hole, and elastic button is exposed to the writing case base, and spring and dop are positioned at cavity.

Described writing case lid edge is provided with a grapple, the grapple direction inwards, its Width through hole is smaller, and its position is corresponding with elastic locking device.

Link together by moving connecting mechanism between described writing case base and the writing case lid.

The beneficial effects of the utility model are:

The utility model is simple in structure, and it is convenient to open, as long as once can automatically opening by elastic button, convenient and practical; Under the cover closing state, sound construction between lid and the base, the objects such as its inner pencil can not drop out.

Description of drawings:

Fig. 1 is that the utility model integral body is faced structural representation;

Fig. 2 is the utility model unitary side TV structure schematic diagram;

Fig. 3 is A-A sectional structure enlarged diagram.

Among the figure: 10, writing case base; 101, elastic locking device; 1011, elastic button; 1012, spring; 1013, dop; 1014, through hole; 1015, cavity; 20, semicircle spring; 30, writing case lid; 301, grapple; 302, moving connecting mechanism.

The specific embodiment:

The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.

Embodiment: see Fig. 1, Fig. 2 and shown in Figure 3, a kind of self-closing writing case comprises writing case base 10, semicircle spring 20 and writing case lid 30, and the edge of described writing case base 10 is provided with an elastic locking device 101; One end of semicircle spring 20 is fixed on writing case base 10 bottoms, and an other end is fixed on the writing case lid 30.

Described elastic locking device 101 comprises elastic button 1011, spring 1012, dop 1013 and through hole 1014, and elastic button 1011 is exposed to writing case base 10, and spring 1012 and dop 1013 are positioned at cavity 1015.

Described writing case lid 30 edges are provided with a grapple 301, grapple 301 directions inwards, its Width through hole 1014 is smaller, and its position is corresponding with elastic locking device 101.

Link together by moving connecting mechanism 302 between described writing case base 10 and the writing case lid 30.

Operation principle:

A kind of self-closing writing case, elastic locking device 101 comprise elastic button 1011, spring 1012, dop 1013 and through hole 1014, and elastic button 1011 is exposed to writing case base 10, and spring 1012 and dop 1013 are positioned at cavity 1015; Writing case lid 30 edges are provided with a grapple 301, grapple 301 directions inwards, its Width through hole 1014 is smaller, and its position is corresponding with elastic locking device 101, when writing case base 10 and writing case lid 30 are combined, grapple 301 is inserted in the through hole 1014, and under the effect of spring 1012, grapple 301 reverse fastenings are in the lower edge of through hole 1014; When pressing elastic button 1011, through hole 1014 extends internally, holder is opened between the lower edge of grapple 301 and through hole 1014, and an end of semicircle spring 20 is fixed on writing case base 10 bottoms, an other end is fixed on the writing case lid 30, so writing case lid 30 is under the effect of semicircle spring 20, writing case lid 30 automatically springs open, and reaches the purpose of automatically opening writing case lid 30.
