Abstract
The utility model relates to a rotary lifting hinge, which comprises a shaft core and a hinge which is matched with the shaft core, wherein, the hinge is composed of an upper hinge and a lower hinge, the upper hinge is matched with the rotation of the shaft core and the upper and the lower slide through the shaft sleeve at one side of the upper hinge, the lower hinge is fixed on the shaft core through the shaft sleeve at one side of the lower hinge, and the lower end of the shaft sleeve of the upper hinge is matched with the top end of the shaft sleeve of the lower hinge by the helical butt-joint. The utility model is mainly used for a vertical hinged door. When a door is opened, the door can automatically lift a distance in company with the opening of the door. When the door is closed, the door can automatically descend and reset because of the own weight of the door, and the lower edge of a door leave does not contact ground in the process of the opening of the door. The utility model is suitable for the sealing vertical hinged door of clean room.
Description
The utility model relates to a kind of and uses hinge, particularly relates to a kind of rotary lifting hinge.
Use the various sealed vertical hinged door of ready-made hinge, when requiring door to close, door leaf surrounding and doorframe surrounding are tightly seamless, but its disadvantage is to connect edge under the door leaf to open and close in the closed procedure at door, and inevitable the generation with ground rubbed, not only damage door leaf and ground, and generation dust, as be used for the toilet, it has just become one to send out the dirt source, causing lustration class to reduce, is an insoluble problem of toilet's interior trim.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, and its Shi Menhui that opens the door is risen automatically, and door can the automatic rotary lifting hinge that descends and reset at closing time.
The utility model rotary lifting hinge is to realize like this, it comprises a core, and the hinge that cooperates with the axle core, wherein, hinge is made up of last hinge and lower jaw, and last hinge rotates and slides up and down with the axle core by its axle sleeve on one side and cooperates, lower jaw is fixed on the core by its axle sleeve on one side, last hinge axle sleeve lower end cooperates with the helical form butt joint with lower jaw axle sleeve upper end, and upper and lower hinge is provided with installing hole, is used for upper and lower hinge is separately fixed at door leaf and doorframe.Can plug be set in last hinge upper end and lower jaw lower end, make it attractive in appearance.
The operating principle of the utility model rotary lifting hinge is, during use, lower jaw is fixed on the doorframe by securing member, and last hinge is fixed on the door leaf by securing member, when door is opened, last hinge rises along helix, thereby door is risen thereupon, when door is closed, because the deadweight of door, last hinge descends along helix, and door descends thereupon and resets.
The advantage of the utility model rotary lifting hinge is, and is simple in structure, easy to use, when door was opened, student edge can not contact with ground and produce friction, when door is closed, contact tightly with ground, need not use door closer, moreover, when door is closed, the butt joint of upper and lower hinge is a slice, is positioned at same increasing on the face, thereby the thickness when hinge is closed up reduces 50% than ready-made hinge, can satisfy the installation requirement of metal door, be specially adapted to the sealing vertical hinged door of toilet.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
