Abstract
The invention relates to an upward opening type hinge structure. The hinge comprises an upper hinged seat and a lower hinged seat which are connected by a pin shaft, wherein at least a long uncovering spring and a short return spring are arranged between the upper hinged seat and the lower hinged seat. By arranging more than two springs with different heights in the same stressing direction of the hinge, the quantity of compressed springs is different when the moving part of the hinge is in different positions, so that the linear force change requirements of the non-single stage spring can be realized, thereby realizing the nonlinear force change when the moving part is in different positions. When the hinge is mounted on an upward opening type microwave oven, the oven cover can be stopped in at least two different positions, thereby reducing the damage to the product and simultaneously realizing the requirements for different opening angles (in normal use, food can be taken out by simply opening the door for a small angle, and a big angle is required when big food is taken out/ put in and when the microwave oven is cleaned). The upward opening type hinge structure has the advantages of simple and reasonable structure and wide application range, and is convenient to operate.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
First embodiment
Referring to Fig. 1-Fig. 5, opening type hinge structure on the basis, described hinge 3 comprise last free bearing 4 and the following free bearing 5 that connects by bearing pin 11, are provided with uncap spring 6 and the return spring 13 that one is long and the other is short between the upper and lower free bearing at least.Last free bearing 4 and following free bearing 5 are respectively arranged with rotating shaft 12 and lower rotary shaft 9; The uncap two ends up and down of spring 6 and return spring 13 join with last rotating shaft and lower rotary shaft respectively.The spring 6 of uncapping is set in return spring 13 outsides, and the uncap lower end of spring and return spring of lower rotary shaft 9 end face correspondences is provided with down locating slot 9.1.
Uncap spring 6 and return spring 13 upper ends join by push rod 7 and last rotating shaft 12; Correspondence spring and the return spring upper end of uncapping in push rod bottom surface is provided with locating slot 7.1.Push rod 7 upper ends are provided with the U-shaped axle bed and last rotating shaft 12 surfaces are rotationally connected, and the corresponding U-shaped axle bed in last rotating shaft 12 middle parts is provided with locating slot 12.1, sees Fig. 6.
Also be provided with sleeve 8 between return spring 13 upper ends and push rod 7 bottom surfaces.Also be provided with transmission shaft 10 in the hinge 3; Fixedly connected with push rod 7 in the transmission shaft upper end, the transmission shaft lower end passes lower rotary shaft 9 backs and is connected with positive stop 10.1.Be provided with gum cover tube 14 between transmission shaft 10 and the lower rotary shaft 9.
Its working principle is: referring to Fig. 5, fixing when the following free bearing 5 of hinge, when last free bearing 4 was in complete closed state, uncap spring 6 and return spring 13 were simultaneously to bigger power of last free bearing, and after the external force of last free bearing removed, last free bearing can be opened fast.Referring to Fig. 7, because return spring 13 is shorter, return spring did not just produce active force to push rod when last free bearing opened to the α angle, simultaneously, when last free bearing was connected with bell, the acting force of the spring of uncapping combined with bell gravity, free bearing was in open the state of α angle.Referring to Fig. 6 and Fig. 8, last free bearing is applied an external force of upwards opening, last free bearing in conjunction with the active force of the spring of uncapping, can open to bigger angle beta again.
Second embodiment
Referring to Fig. 9-Figure 11, push rod 7 is the T font of putting upside down, and the lower end is positioned at free bearing 5 inboards down; Following free bearing inboard is provided with shell fragment 15, and the shell fragment surface is provided with positioning convex 15.1 towards the push rod direction.Other does not state part with first embodiment.
Its working principle is: referring to Fig. 9, when the following free bearing 5 of hinge is fixed, when last free bearing 4 is in complete closed state, uncap spring 6 and return spring 13 simultaneously to bigger power of last free bearing, after the external force of last free bearing removes, last free bearing can be opened fast, and push rod 7 downsides slide on the lower, planar of shell fragment 15 positioning convex 15.1, touches until push rod downside and positioning convex 15.1.Referring to Figure 10, when push rod downside and positioning convex 15.1 touched, shell fragment 15 produced and uncaps spring 6 opposite effect power; Simultaneously, because return spring 13 is shorter, return spring is just to push rod generation active force, so last free bearing opens to the α angle when push rod downside and positioning convex 15.1 touch.Referring to Figure 11, last free bearing is applied an external force of upwards opening, make the push rod downside slip over positioning convex, the spring 6 of uncapping no longer is subjected to the resistance of shell fragment, and last free bearing can open to bigger angle beta under the spring action of uncapping.
