Among the figure: 1 is upper hinge, and 1.1 is limited wall, and 1.6 is first connector, 1.7 be second connector, 2 are following hinge, 2.1 is spacing block set, 2.2 be catching groove, 2.5 is joint among three members, 2.6 for dodging mouth, 2.7 be the 4th connector, 3 is torsion spring, 4 is the torsion spring pin, 5 is damper, 6 is spring catch, and 7 is door body assembly, and 7.1 is gate stop.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 4, the opening structure of the micro-wave oven of this band buffer unit, comprise the upper hinge 1 that is fixed on the body assembly 7, with the following hinge 2 on the body of heater that is fixed on micro-wave oven, hinged between door body assembly 7 and the body of heater by upper and lower hinge, be provided with elastic component between its upper hinge 1 and the following hinge 2, upper hinge 1 also is connected with damper 5.
It is hinged with play hinge 2 that the both sides of upper hinge 1 are provided with first connector 1.6, and it is hinged by an end of spring catch 6 and damper 5 that the middle part of upper hinge 1 is provided with second connector 1.7.An other end of damper 5 is hinged with the connector 5.1 that is fixed on the micro-wave oven.Wherein, damper 5 is a hydraulic damper.
First connector 1.6 of the corresponding upper hinge 1 in the both sides of following hinge 2 is respectively arranged with joint among three members 2.5, and the corresponding damper 5 in middle part has dodges mouth 2.6, dodges mouthful 2.6 both sides and is provided with the 4th connector 2.7.It is hinged that joint among three members 2.5, first connector 1.6, the 4th connector 2.7 are passed successively by torsion spring pin 4 respectively in the both sides of upper hinge 1 and following hinge 2.Be respectively arranged with torsion spring 3 on two torsion spring pins 4.One end of two torsion springs 3 pierces into respectively and is fixed on first connector 1.6, and an other end is fixedlyed connected with the catching groove 2.2 that is arranged on the 4th connector 2.7 respectively.
When the door body assembly 7 of micro-wave oven was closed, the interlocking mechanism's (figure does not mark) that is arranged on the microwave oven body (figure does not mark) interlocked with a gate stop 7.1 of body assembly 7, and torsion spring 3 is in compressive state, and damper 5 is in the state of not stressing.
When the door body assembly 7 of micro-wave oven is opened, the interlocking mechanism's (figure does not mark) that is arranged on the microwave oven body (figure does not mark) is separated with a gate stop 7.1 of body assembly 7, door body assembly 7 is opened under the restoring force effect of torsion spring 3, simultaneously, damper 5 pressurizeds, and play cushioning effect, when being opened, a body assembly 7 has damping.After it was effectively avoided interlocking mechanism's (not marking among the figure) and gate stop 7.1 separates, door body assembly 7 was opened under the restoring force effect of torsion spring 3 automatically rapidly; Perhaps, a body assembly 7 can't be opened automatically because of avoiding a body assembly 7 to open the restoring force of deliberately turning down torsion spring 3 rapidly.Wherein, door body assembly 7 is owing under limited wall 1.1 actings in conjunction of the spacing block set 2.1 of following hinge 2 and upper hinge 1, limit its maximum opening angle.
When the door body assembly 7 of micro-wave oven is closed again, torsion spring 3 is compressed gradually, until gate stop 7.1 interlocks again with interlocking mechanism's (not marking among the figure), at this moment, torsion spring 3 is in most compressed state, the torsion maximum that it is subjected to, and damper 5 discharges again, be in the state of not stressing once more, door body assembly 7 is closed.
