Abstract
The utility model provides a primary and secondary hinge, includes sub - hinge, female hinge, axis and sealed bearing, sub - hinge passes through sub - hinge sleeve pipe and female hinge sleeve pipe and axis swivelling joint respectively with female hinge, sealed bearing installs in the sub - upper and lower both ends of hinge epaxially, and this sealed bearing locates the system with sub - hinge connection has the sealing ring, sub - hinge cover inside pipe wall complex has the lubricating grease layer, closely laminates with the fusiformis fastening sleeve pipe that axis an organic whole was made in this lubricating grease layer, but the system has the logical groove of the sub - hinge of suit on female hinge. The utility model overcomes the tradition hinge, articulated insecure, the easy technological problem who warp of door frame is through adopting alphabetical hinge connection form for the hinge is lighter, and the atress is more even, uses door frame non -deformable for a long time, and closure, the effect that gives sound insulation obviously improve.
Description
Technical field
This utility model relates to the hinge device of vertical hinged door, especially a kind of primary and secondary hinge.
Background technology
Between door and doorframe, many use world hinge supports fastening now, conventional hinges needs to install in the perforate of doorframe place when mounted, firm in structure in order to ensure doorframe stress place, typically require and install backing plate additional, so not only time-consuming take a lot of work, and life-time service so that doorframe easily causes door frame distortions because of unbalance stress, has a strong impact on normal use.Further, conventional machining process is not enough to the lubricant effect of hinge, abnormal sound occurs when frequently resulting in use, has a strong impact on the normal use of hinge.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art part, it is provided that a kind of firm in structure, durable, easy for installation, a kind of primary and secondary hinge of high lubricating effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of primary and secondary hinge, including sub-hinge, female hinge, axis and sealing bearing, described sub-hinge is connected with middle shaft rotation respectively through sub-hinge sleeve and female hinge sleeve with female hinge, described sealing bearing is installed on the axis of sub-hinge upper/lower terminal, and this sealing bearing and sub-gemel connection place are shaped with sealing ring；Described sub-hinge sleeve inwall is compounded with grease layer, and this grease layer fits tightly with the integrally formed fusiformis fastening sleeve pipe of axis；Described female hinge is shaped with the groove that can be set with sub-hinge.
And, described axis two ends are connected by pin is fixing with female hinge.
And, described female hinge is uniform with on sub-hinge is shaped with multiple installing hole, and this installing hole can be circular hole or elongated hole.
Advantage of the present utility model and economic effect be:
1, this utility model overcomes conventional hinges, hinged insecure, the technical barrier that doorframe is easily deformed, by adopting primary and secondary gemel connection form so that hinge is lighter, is more uniformly stressed, long-time use doorframe is unlikely to deform, and closure, soundproof effect significantly improve.
2, this utility model cooperates with sealing bearing by adopting sub-hinge inwall to be compounded with grease layer, in one-step molding manufacturing, sub-hinge is closely cooperated with fusiformis fastening sleeve pipe, and in sleeve pipe, it is full of grease, both ensure that the service precision of hinge, also the abrasion of hinge inner sleeve with axis is preferably minimized with degree of oxidation simultaneously, substantially prolongs the use time.
