The specific embodiment

To shown in Fig. 2 (B), basically, the hinge mechanism of this case is to be connected parts 5, one extensible members 6 by a fixture 1, one movable part 2, a part 3, the one relaying spares 4, that are coupling, and/or a slide rail 7 is formed as Fig. 1 (A).

Wherein, fixture 1 is a support body, for example L shaped support body, it opens frame hole 13 in level or

vertical frame face

11 and 12, with known fixed form, for example screw passes through, and be locked in a fixture, the openend apical margin of cupboard for example, but not as limit, it is also riveted between the two or welding manner is fixed, and all belongs to the category of this case.In addition, be provided with an axis part 14, so that be coupling with movable part 2 formation in vertical rack face 12 apical margins.This axis part 14 is at least two rings 141 of frame face 12 apical margins formation, then opens at least one therebetween and lacks 142, so that ccontaining for the prominent relatively at least one axle collar 211 established of movable part 2, passes through the frame ring 141 and the axle collar 211 with a pivot pin 143 again, forms the effect that is coupling.

And the creation characteristic of this case is, this at least one scarce 142 interior side direction are extended a L shaped frame sheet 144, and its free end is for linking a horizontal coak 144a, so that combine with an on-slip part 8.This on-slip part 8 is an elastic body, and is made such as rubber, and its bottom opening 81 is to be intercalated in coak 144a, and makes the seat rank 82 in its stage casing and pivot pin 143 formation overlap and press, and side then forms an arc edge 83 in addition.

Movable part 2 is a plate body, and a

pivoted connection end

21 and 22 are respectively established in its two ends, and wherein, at least one axle collar 211 of inboard pivoted connection end 21 is to be articulated in fixture 1, and the axis hole 222 of the diaxon sheet 221 of outside pivoted connection end 22 then articulates with being connected part 5, to form interlock.Wherein, movable part 2 is provided with at least one plate hole, so that and live animal, link with aforesaid locking mode such as door leaf, but not as limit, also be able to riveted between the two or the seam mode links, also can obtain the effect of synchronous interlock.

Perhaps, as shown in the figure, it is the fixed track 71 that connects a slide rail 7 at fixture 2 end faces, in addition with a movable rail 72 and its socket, movable rail 72 can be slided along fixed track 71.This activity rail 72 is connected with live animal via some rails hole 721, and live animal can be moved along with movable rail 72, and can be along fixed track 71, and is accommodated in fixture inside.

See also Fig. 3 to Fig. 5, when being in when raising state, touch movable rail 72 because on-slip part 8 end faces are unlikely, therefore, movable rail 72 can be along fixed track 71 slippages.And when mode of operation, when movable rail 72 formed an oblique angle, its root edge was because of touching arc edge 83 top corners, and the formation anti-slip effect.In addition when closure state, then movable rail 72 ora terminalis stop because of being subjected to arc edge 3, consequently can't on push away.Make this case because of having the on-slip device, on using, more highlight its safe effect.

The part 3 that is coupling is a support body, it is fixedly arranged on fixture 1 below, for example with the combination of spot welding mode, the one end is provided with a not-go-end 31, and opens a stomidium 311, and two cover contact pin 32 are then stretched out in the stage casing downwards, it opens circle hole 321 relatively, so that for being coupling with relaying spare 4, the top is then opened microscler hole slot 322 relatively, so that for supporting expansion link 60.

Relaying spare 4 one U-shaped support bodys, microscler the groove 41 that the one end is opened relatively so that utilize diaxon bolt 42 to be riveted on circle hole 321 by a groove 41 respectively, makes relaying spare 4 with respect to the part 3 that is coupling and can be and reverse.Relaying spare 4 end in addition then forms a pair of microscler access slot 43 relatively, so as with after the part 5 that is connected chatted be coupling.In addition, form a protrusion 44, so that utilize its contiguous lateral margin 441 of part 5 that is connected as a fulcrum in each

groove

41 and 43 of access slots.

Being connected part 5 also is a U-shaped support body, width is between relaying spare 4 and movable part 2, therefore, the two side of corresponding axis hole 222 in two ends and access slot 43 positions forms a pair of keyhole 51 and a pair of mortise 52 respectively, so that pass through axis hole 222 and mortise 52 with

pivot pin

53 and 54 respectively, and be incorporated into keyhole 51 and access slot 43, make movable part 2, linking part 5 and relaying spare 4 can produce relative motion.This each mortise 52 is to be positioned at a rectangular depression portion 55, so that its corner 551 can form a fulcrum (also as stop) with lateral margin 441.In addition, be connected the bar groove 56 that a non-perforation is opened in part 5 bottoms, the extensible member of chatting after making 6 is able to therebetween ccontaining.

Extensible member 6 is to be provided with an expansion link 62 in a body of rod 61 ends, and with its by and be socketed on the register hole 631 of a support member 63 after, link with vertical direction with an axostylus axostyle 64 in addition, and the two side free end of support member 63 is respectively opened one and is connect hole 632, pivot pin 54 is incorporated into by access slot 43 connects hole 632, and this support member 63 is incorporated between the relaying spare 4.And this axostylus axostyle 64 and be cross-placed on a movable piece 65 two sides one ends formed two U-lags 651 in top and two hole slots 322, its in addition end then be provided with a screw 652 so that with an adjustment part 66 by stomidium 311, and be screwed together in screw 652.When rotation adjustment part 66, can impel movable piece 65 the part 3 that is coupling in, laterally to move, and the related axostylus axostyle 64 that makes is because of displacement, and makes expansion link 62 stretch out or retraction, and the position of the fulcrum and the cushion effect of change expansion link 62, it is adjustable making movable part 2 closing speeds.In addition, other has an extension spring 67 to be located between the bottom outlet 45 of the bottom outlet 653 of movable piece 65 and relaying spare 4, and makes relaying spare 4 produce a pulling force, in order to reversing.Into person is arranged especially, when this extensible member 6 is implemented, is good with hydraulic stem or atmospheric pressure pole.

This case through organize upright after, promptly shown in Fig. 2 (A) and Fig. 2 (B), please consult Fig. 3 to Fig. 5 again, when live animal being opened as desire, this moment, movable part 2 was that fulcrum reverses with fixture 1, made to be connected part 5 in turning course, also spurred relaying spare 4 in the lump, making it is fulcrum with the part 3 that is coupling, and upwards reverses gradually.At this moment, 62 of expansion links be subjected to gradually the user external force and in contract (rise state as shown in Figure 4), take in to (rest point) the most in short-term up to it, this movable part 2, each fulcrum that is connected part 5 and relaying spare 4 form a straight line, make whole group pivot structure form as shown in Figure 5 opening.And movable rail 72 can be along the fixed track 71 inside slippages of being located at movable part top, with as taking in.

Otherwise, when desiring closure, then press down live animal, make it cross rest point, and make expansion link 62 stretch gradually, relaying spare 4 is reversed downwards gradually, and make linking part 5 and movable part 2 move down (the slow state that falls) synchronously, touch fixture 1 up to live animal 2, and its openend sealing is formed.

This case institute announcement technology is a kind of of preferred embodiment, and the patent right category of this case is not all taken off in Ju Bu change or modification and come from the technological thought of this case and be easy to know by inference technology by the people who has the knack of this skill such as.
