The shape of case body 2 and structure, installation method are not limited to shown in the present embodiment, for example can be that one flat plate is cast as the case shape, also can be welded to one another into the case shape to the connecting sheet of polylith rectangular flat.

Lid 4 can separate from case body 2, so long as the bottom surface 23 opening opposing portions of covering and case body 2, no matter any shape all can, the lid 4 of present embodiment is around the one flat plate in four limits, except that the limit of the back side 24 sides that are configured in case body 2, three limits all are bending, by top 41 and a pair of left and right sides face 42 and a face side side 47 constitute.The lower end that the width of lid 4 is set at left and right sides face 42 can be placed on the size of the side of case body 2 with the upper end of flat board 3.

Secondly, the details to linkage of the present invention describes.The linkage of present embodiment as rotatingshaft, rotates lid 4 with near the hinge axis 25 the top at the back side 24 that is located at case body 2 on above-below direction.

On the back side 24 of case body 2, also shown in the planimetric map (a) and profile (b) at the back side 24 of Fig. 3, form parallel and at a pair of hinge axis 25 of the rectangle of giving prominence to respectively on the direction of dull and stereotyped 3 sides towards the side along the top.Each hinge axis 25 is configured on the position of equal height of both sides at the back side 24, becomes identical shaped.In addition, at present embodiment, be the degree of the thickness of slab W1 of flat board to the side of hinge axis 25 with the outstanding width W 0 of dull and stereotyped 3 direction, but also can give prominence to more than it.

On the left and right sides face 42 that with this hinge axis 25 is the lid 4 that rotates of center as the side plan view of the case 1 of Fig. 4 and shown in Figure 5 with the local amplification of Fig. 4, connect the hole 43 that forms a pair of circular, the hole 43 of each circular is on the relative position of left and right side 42, form identical shaped, and be configured in one distolateral (the making under lid 4 and the state that case body 2 is connected the tip side that forms in the back side of body 2 24 sides) of left and right side 42.In the hole 43 of this a pair of circular, insert the hinge axis 25 that is located on the back side 24.At this moment, connect in the length L 1 (with reference to Fig. 5) of hinge axis 25 longitudinal directions and the hole 43, shorter than the diameter in hole 43, the relation of the diameter＞L1 in formation hole 43.

And the groove 44 that can insert hinge axis 25 is equipped with in hole 43 on the part of its periphery.Groove 44 extends setting from the outer extending direction that circumferentially is roughly the diameter line in circular hole 43 in the hole 43 of circular, and front end is to foreign side's opening.At present embodiment, top and bottom and lid 4 top 41 parallel, width with regulation.Groove 44 has the width W 2 greater than the thickness of slab W1 of flat board at least, inserts in the hole 43 of circular, to foreign side's opening from the outside in order to make hinge axis 25.

The groove 44 of present embodiment covers fully at lid 4 under the state (lid 4 closing state) of the opening portion of case body 2, forms front 22 from casing 2 along stretching out to the direction at the back side 24, to outside opening, but may not form groove 44 on this direction.

And the shape of the side 42 of the lid 4 of present embodiment is not a square, and forming the limit that groove 44 is made with external communications is the roughly trapezoidal of hypotenuse.Therefore, the length of groove 44 is different up and down, and then the groove outer periphery 46 of downside are not acute angles, has fillet by grinding to wait.Therefore, the hinge axis introducing port that makes groove 44 expands to the outside to be opened, and hinge axis 25 is inserted easily taken off, and does not cut the danger of hand simultaneously, can guarantee human body safety.And 42 one distolateral oblique notch part is set in the side, and make roughly trapezoidally, as shown in Figure 6, be when lid 4 is rotated, avoid the lower end of side 42 and side to interfere with dull and stereotyped 3 upper-end surface, hinder and rotate smoothly and be provided with.

And then the rotation restrictor 45 that inner hinge axis 25 contact, limited lid 4 rotations is equipped with and is inserted in hole 43 in the part of its periphery.The rotation restrictor 45 of present embodiment forms fan-shaped, on one side on the elongation line of groove 44, being configured in and not hindering from the position that the groove 44 of hinge axis 25 inserts, another side is along the radially extension setting of circular port 43.

The fan-shaped angle of rotation restrictor 45, prominent establish the position, can freely determine with the position relation of groove 44.Promptly determine the permissible range of rotation by the correlation of these key elements.At present embodiment, the angle R1 of rotation restrictor 45 is 90 degree, above the lid 4 from such lid 4 closed conditions of Fig. 4, Fig. 5 to Fig. 7 41 with 24 one-tenth parallel states in the back side of case body 2, promptly in angle (90 degree)=90 scopes of spending (scope shown in the A of Fig. 5 and Fig. 7) of 180 degree-fans, lid 4 can rotate.At present embodiment, the rotation lower position of lid 4 is corresponding with the position that lid 4 is closed the opening of case body 2.

And then, one side in the rotation restrictor 45 of present embodiment on the fan-shaped elongation line that is located at groove 44, the dull and stereotyped hole of processing easily.The linkage of being made up of the hole 43 of hinge axis shown in the foregoing description 25 and circular for example when case body 2 and lid 4 are made of sheet metal, can form by laser beam cutting.At this moment, because case body 2 and lid 4 also can launch its visible outline formation by laser cutting processing, so can carry out with the cut-out processing of circular port 43 the cut-out processing of this visible outline and hinge axis 25 by working continuously.

Like this, the flat board of apparatus porose 43 and have hinge axis 25 the simple combination of flat board just can realize handle switch mechanism dull and stereotyped and flat board, and then, owing to be restricted, needn't adopt fixed structures such as locking mechanism and embedding part by rotation restrictor 45 switching ranges are set in hole 43.Therefore, increased the degrees of freedom of the shaped design of case body 2 and lid 4.

According to above structure, as shown in Figure 8, case body 2 and lid 4 are configured to make the extending direction of groove 44 consistent with the thickness direction of hinge axis 25 when being in separated state, and case body 2 and hinge axis 25 are inserted in the groove 44 of logical lid 4, insert in the circular port 43.(, as shown in Figure 7, on make lid 4, under 41 states of vertically toppling over, can import hinge axis 25) at present embodiment

And if lid 4 is forwards rotated, then case body 2 is connected with lid 4.Afterwards, as long as become such coupled condition, just as Fig. 6, shown in Figure 7, lid 4 be that rotate at the center with hinge axis 25, this limit rotation the shape that adapts to rotation restrictor 45, be provided with the position, and groove 44 the scope that concerns of position in.Fig. 6 represents to make lid 4 to turn to half (45 degree) of rotatable scope, the state that lid 4 is opened.

Wanting to make lid 4 when case body 2 breaks away from, the same with hinge axis 25 introduction holes 43 time, the state (Fig. 7) that top 41 of lid 4 is moved to vertically topple over, by intactly extraction upward of lid 4, hinge axis 25 is extracted (Fig. 8) by groove 44.At this moment, at present embodiment, as shown in Figure 7, the top by groove 44 and side contacts with dull and stereotyped 3 ear end face, the rotation of prevention lid 4, and this position becomes the upper limit position of rotation.Under such state, can stablize the operation that circular port 43 is broken away from from hinge axis 25.

Like this, by making the hinge axis 25 that on pair of plates, forms and the combination in hole 43, just can provide a kind of do not need complicated processing and other parts, simple, mounting or dismounting easily, can limit the linkage of rotation.

Therefore, as in the housing of electronic equipment, adopting this linkage, after electronic equipment is placed on the position of regulation, carry out the maintenance of inner member easily.In addition, if the fare box in parking lot etc., then as shown in Fig. 1, Fig. 2, the 47a of hole portion on the 22a of hole portion that then constitutes the front will be located at case body 2 and the face side side 47 that is located at lid 4 is connected with padlock etc., Security in can guard box (if constitute by the metallic flat board especially, just can bear the external environment condition variation, prevent artificial destruction), the cashier can make lid 4 leave case body 4, reclaims at short notice to be placed on inner currency and bank note etc.

More than to hinge axis 25 is set on case body 2, the embodiment of case who connects the hole 43 of hinge axis 25 on lid 4 in being provided with is illustrated, even but the hole 43 of circular is set on case body 2, the case of hinge axis 25 is set on lid 4, linkage according to the invention too, this situation is also contained among the present invention.When case body 2 sides form the hole 43 that is roughly circle, the a pair of edge 21a of portion that is located at 24 sides, the back side is further extended upward to be provided with, shown in Figure 2 be provided with hinge axis 25 positions near, groove 44 makes opening upward, connect to form the hole 43 of circular, be arranged on the lower end that lid makes 4 side 42 hinge axis 25 is outstanding.

Rotation restrictor 45 also can have two places shown in Fig. 9 (a), Fig. 9 (b).At this moment, one side of both sides' rotation restrictor 45 becomes rotating scope to the crossing angle A on the limit of center prolongation.Rotation restrictor 45a, 45b shown in Fig. 9 (a) the in fact rotation restrictor 45 with Fig. 5 of front embodiment is identical, it is the scope of 90 degree, though be rotating, but, increased the stability of rotating or limiting when rotating because the bi-side of hinge axis 25 (the table the inside at the back side 24) contacts with rotation restrictor 45a, 45b respectively, fixes.

When wanting to enlarge the scope of turning, shown in Fig. 9 (b), the rotation restrictor 45c that fan-shaped angle work is acutangulated also can only be set, by on the position roughly relative, rotation restrictor 45d being set with the position of rotation restrictor 45c, in identical slewing area, also can increase the stability of rotating and limiting when rotating, determine rotating scope effectively.

In addition, the shape that is located at a rotation restrictor 45 on the hole 43 in Fig. 9 (a), Fig. 9 (b) is roughly the same, even but the shape that has nothing in common with each other also has no relations, can carry out various changes according to the restriction in the designs such as intensity of rotating permissible range, pivotal position, dull and stereotyped thickness of slab and material, requirement.

Another embodiment of expression rotation restrictor 45 among Fig. 9 (c).The fan-shaped angle of the rotation restrictor 45e of Fig. 9 (c) is obtuse angle (greater than 90 degree), and (slewing area=180 degree-fan-shaped angles) can narrow down the slewing area A of hinge axis 25.But lid 4 can not be closed fully in the embodiment of Fig. 9 (c).

42 one-tenth rectangles in side of lid 4 shown in Figure 9, the length up and down of groove 44 about equally.In addition, in the embodiment shown in fig. 9, interval between the left and right side 42a～42c of the width of formation lid 4 is bigger with dull and stereotyped 3 interval (width of opening portion) than the side, and the inner face of each left and right side 42a～42c forms and can slip with the outside of flat board 3 with the side and rotate.

In identical rotatable scope, shown in Fig. 5 and Fig. 9 (a), owing to the shape of rotation restrictor 45, the pattern of position can be realized multiple mode, so can be according to changing as dull and stereotyped thickness of slab, material, intensity and other restriction that designs.

The hinge axis 25 of the foregoing description, as shown in Figure 3, be located at from the top at the back side 24 of case body 2 and leave on the position of distance of regulation, back side 24a that can certainly be shown in Figure 10 (a) is such, even make the top longer than the width of case body 2, hinge axis 25 is integrated with the top, as long as do not hinder handle switch, also has no relations.In addition, hinge axis 25 may not be rectangle, and for example back side 24b that also can be shown in Figure 10 (b) is such, has trapezoidal hinge axis 25b.In addition, back side 24c that also can be shown in Figure 10 (c) is such, and the hinge axis 25c of T font is housed.In any case, as long as hinge axis 25 have with hole 43 in connect, make rotating width W 3 to be at least the shape of thickness of slab W1.
