Description
Technical field
The measuring instrument that the present invention relates to have dismantled and assembled lid (cover) is with housing (case), and this invention is very suitable for as the shell that is installed in the temperature regulator on the control panel (panel) etc.
Background technology
Fig. 3 (a) and (b) are existing oblique view with housing of detatchable cover, and Fig. 4 is the B-B sectional view of Fig. 3 (b).Among the figure, 1 is the housing that temperature is transferred the shell of device etc., 2 lids for the peristome that is installed on housing 1.Be formed with tabling piece 3 outstanding and that be parallel to each other, baffle plate sheet 4 and flexure strip 5 at the back side of lid 2.
Tabling piece 3 is darted at the inboard a little position of the side end 20a of the race portion 20 on the lid 2 towards housing 1 direction, constitute the corresponding fitting portion of race portion 1a with housing 1 thus.Baffle plate sheet 4 is configured to relative and be positioned at the position a little in the inner part of side end 20b of opposition side of the side end 20a of race portion 20 across the peristome 10 of lid 2 and tabling piece 3, enters in the housing 1 from side end 20b in order to prevent grey dust.Flexure strip 5 is positioned at the position than the side end 20b of baffle plate sheet 4 more close race portion 20, and from outstanding setting of side end 20b part slightly in the inner part than race portion 20, shown in Fig. 3 (a), around flexure strip 5, be formed with flexure strip 5 is divided into the support sector of flexure strip 5 and the plane コ word shape grooving 9 of race portion 20 and flexure strip 5, the flexure strip 5 that is positioned at the inboard of this grooving 5 can produce elastic deformation in the other direction to the center position of the peristome 10 of lid 2 or its.That is, flexure strip 5 is a fulcrum with the part 5a of the terminal room of two groovings 9, to the center position of the peristome 10 of lid 2 or its elastic deformation takes place in the other direction.In addition, be integrally formed into removal stop section 6, formed at free end simultaneously and pushed with projection 7 with inclined-plane 6a at the summary central part of flexure strip 5.Removal stop section 6 is colluded by the drop-proof hole 1A on the housing 1 and tangles, and thus lid 2 is fixed in housing 1.
In addition, 8 for the substrate by the electronic unit of the operating portion that attemperator etc. is housed, expression portion, is arranged on the space between fitting portion 3 and the baffle plate sheet 4.
The following describes its action.
When lid 2 is installed, with the opposite side that is formed with drop-proof hole 1A one side of housing 1, the tabling piece 3 of lid 2 is inserted housings 1, make the race portion 1a tabling of itself and housing 1.And lid 2 is given as security pressure to housing 1, and at this moment, flexure strip 5 partly is a fulcrum with 5a, elastic deformation takes place, be located at removal stop section 6 on the flexure strip 5 and colluded by the drop-proof hole 1A on the housing 1 and tangle, flexure strip 5 returns to original position, thus, lid 2 is mounted on the housing 1.
When being folded down lid 2, push pushing of flexure strip 5 to the inboard of housing 1 with projection 7, so, on this direction, flexure strip 5 partly is a fulcrum generation elastic deformation with 5a, and the prolong knot of removing thus between removal stop section 6 and drop-proof hole 1A that colludes closes, at the drop-down body 2 of uncapping of this state, promptly finished being folded down operation.
Existing housing with detatchable cover has above formation, because when being folded down lid 2 must partly be fulcrum with the 5a of flexure strip 5, make it that elastic deformation take place by being pressed on pushing of the other end with projection 7, so, the elastic deformation amount of flexure strip 5 is big, for the elastic deformation amount who guarantees that this is big, side end to the space of 4 of baffle plate sheets of the race portion 20 of lid 2 fully must be strengthened, therefore, there is the problem that is used in the space stenosis that substrate 8 is set.
And,, need have the support part of the flexure strip 5 of certain intensity in order on lid 2, to form the big flexure strip 5 of deflection, so and flexure strip 5 self together, also must support the thickness thickening of part, simultaneously also need to strengthen the thickness of lid 2, strengthen its intensity.For this reason, the side end 20b of the race portion 20 of necessary increasing lid 2 maximizes lid 2 to the above-mentioned space of 4 of baffle plate sheets, and this also is one of existing problem.
Further, owing to the space of pushing with projection 7 that flexure strip 5 is set need be located at race portion, therefore, as shown in Figure 4, big to the very little method B change of the race portion 20 of the front of lid 2 from the race portion 1a of housing 1, this also is a problem.
Moreover because the maximization of non-desired lid 2, its result goes up the side surface part 20b of race portion 20 on the top of lid 2 and piles up dust easily.Like this, for example when clean office operation, the dust of accumulation disperses to product, product is brought the influence of evil.
In addition, as mentioned above, flexure strip 5 will have big deflection, must make its length elongated, and therefore, the insertion quantitative change of inserting the lid 2 in the housing 1 is big, thereby the insertion amount that exists this length is limiting the problem of the installation of the wiring substrate that is located at enclosure interior.
Also have, in the control panel installment state, when the necessity that is arranged on the attemperator in the housing 1 being operated from the execution of control panel front, must confirm the expression content, so be necessary operating portion and expression portion are concentrated the front that is arranged on lid 2,, as mentioned above, under the situation of existing housing, there is big dead space in the side 20b of race portion 20 between the baffle plate sheet 4, consequently peristome 10 stenosis of lid 2 are difficult to be implemented in when making lid 2 miniaturizations operating portion and expression portion are concentrated the front that is arranged on lid 2.
