The specific embodiment:

See that shown in Fig. 1-5, the utility model in the present embodiment comprises: hinges fixing reservation 1, hinge casing assembly.

Particularly:

Above-mentioned hinge casing assembly comprises: shell 2, brace 3, travel(l)ing rest 4, extension spring 5, stage clip 6, stage clip guide rod 7, pulley base 8; Brace 3 detachable being connected in the hinges fixing reservation 1, this brace 3 is provided with stopper slot 9, and these travel(l)ing rest 4 bottoms are provided with the gag lever post 10 that is complementary with stopper slot 9.This brace 3 is provided with reference axis 11, shell 2 bottoms are provided with datum hole 12, reference axis 11 is positioned at datum hole 12, thereby realize that brace 3 and shell 2 articulate, datum hole 12 adopts inwardly presses shape to be made toward the flanging mode again, can strengthen the position relation of reference axis 11 like this, the stability of product in long-term use promoted greatly.

One end of last travel(l)ing rest 4 articulates by first pin 13 and brace 3, and the other end of this travel(l)ing rest 4 is equipped with connecting rod 14, and an end of this extension spring 5 is connected with connecting rod 14, and the other end of this extension spring 5 is connected with connecting rod 15 on shell 2 one ends.Above-mentioned shell 2 sides have spacing hole 16, and this connecting rod 14 is positioned at spacing hole 16.This travel(l)ing rest 4 is provided with edge clipping 17, and these shell 2 fronts are provided with the draw-in groove 18 that is complementary with edge clipping 17, and this edge clipping 17 is positioned at draw-in groove 18.

Above-mentioned pulley base 8 articulates by second pin 25 and shell 2 middle parts, and when pulley base 8 rotates to certain angle, the sidewall of pulley base 8 will be fitted with shell 2 inwall sides, reach spacing pulley base 8 functions.Inwardly be pressed with protuberance 24 in both sides, travel(l)ing rest 4 middle part, this protuberance 24 has played the position relation of spacing pulley base 8.The bottom of this travel(l)ing rest 4 adopts segmented to press shape, can strengthen its intensity and tension rigidity like this, and improve product performance in application life and function.The arc port of the bottom of this stage clip guide rod 7 is resisted against on the axostylus axostyle 19 of pulley base 8, travel(l)ing rest 4 is lived in traction, this axostylus axostyle 19 adopts high strength, the stainless steel that finish is good, having solved hinge fully works long hours and produces noise problem, it is bad to have solved the feel that oven door closes the door, and can strengthen sealing function.These both sides of stating travel(l)ing rest 4 have the chute 26 that slides for axostylus axostyle 19, and the two ends of axostylus axostyle 19 are positioned at chute 26.

Above-mentioned stage clip 6 is placed on the stage clip guide rod 7, and an end is resisted against the bottom of stage clip guide rod 7, and the other end is resisted against on the limited block 22 on the travel(l)ing rest 4, thereby makes pulley base 8 bear certain pressure all the time; On the above-mentioned pulley base 8 pulley 21 is installed, pulley 21 is installed on the pulley base 8 by the 3rd pin 20, and pulley 21 can be around the 20 smooth and easy rotations of the 3rd pin, and pulley 21 pulley 21 that can slide around brace 3.

Prevent again that in order to increase travel(l)ing rest semi-finals degree hinge from can guarantee fully that at the shape that works long hours limited block 22 is indeformable, increased the life test performance, the junction between limited block 22 and travel(l)ing rest 4 is provided with projection 23, and this projection 23 is a bridge shape projection.

When shell 2 when the reference axis 11 of brace 3 is done rotary work, brace 3 will draw travel(l)ing rest 4 and produce and shell 2 rotation negative side displacements, thereby make the displacement of travel(l)ing rest 4 do up and down along spacing hole 16.

When shell 2 when the reference axis 11 of brace 3 outwards rotatablely moves, drawing travel(l)ing rest 4 simultaneously does to bottom offset, this section moves direct traction extension spring 5 and produces displacement with stage clip 6, stage clip guide rod 7 along spacing hole 16, thereby the displacement that extension spring 5 and stage clip 6 are produced is discharged the energy storage of spring, this section energy storage will be offset by oven door and opened the weight of different angles, can be in the arbitrarily angled pause function of opening angle thereby reach oven door.

When shell 2 when the reference axis 11 of brace 3 inwardly rotatablely moves, when shell 2 forms certain angle with hinges fixing reservation 1 angle, because the downward pressure that pulley base 8 bears stage clip guide rod 7 all the time, thereby the pulley 21 that makes pulley base 8 is resisted against on the arc surface of brace 3, arc surface and pulley 21 form positive tangent plane, making shell 2 inwardly rotatablely move along reference axis 11 stops, need to use extraneous the promotion firmly can make shell 2 do inside spinning movement, under the inertia of this section active force, make the pulley 21 of pulley base 8 arrive traditional method of indicating the pronunciation of a Chinese character face boundary with brace 3 top arc surfaces, make that shell 2 can be along inwardly rotation automatically of reference axis 11, under this section inertia that rotation operates automatically, make pulley 21 pulley 21 increasing with the traditional method of indicating the pronunciation of a Chinese character face of the arc surface of brace 3, thereby reach locking function, and then reach oven door and closing the door when wanting certain angle, when using extraneous thrust to make oven door arrive certain angle, oven door is closed automatically and is reached locking function.

When opening up into maximum angle, the gag lever post 10 of travel(l)ing rest 4 bottoms links closely with the stopper slot 9 of brace 3 bottoms, the datum hole 12 of travel(l)ing rest 4 bottoms links closely with reference axis 11 covers, the edge clipping 17 of travel(l)ing rest 4 links closely with the draw-in groove 18 in shell 2 fronts, the connecting rod 14 of this travel(l)ing rest 4 links closely with the spacing hole 16 bottom circular arcs of shell 2 sides, by this linking closely everywhere, solve hinge fully and pass through load test fully at maximum opening angle.

Certainly, the above only is an embodiment of the present utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
