A kind of realized using screw thread self-locking function can the parked door hinge of random angle
Technical field
The present invention relates to door hinges, especially a kind of to prevent being automatically closed, door capable of being realized in any angle for door
A kind of parked realized using screw thread self-locking function can the parked door hinge of random angle.
Background technology
In our life, door is ubiquitous, but during the use of door, it is sometimes desirable to it is crack, it is sometimes desirable to
It is half-open, it is sometimes desirable to which that standard-sized sheet, in short, people need door in the parked of different angle, can thus encounter how door to position asks
Topic, after door is opened, if cannot centainly be positioned, door can be forced to close because of wind or collision, can also sometimes
It damages on the door, solution currently on the market is one door-inhale of selection, and still, one side door-inhale is only used for the standard-sized sheet of door
State, be on the other hand required for carrying out on door in the installation process of door-inhale punching it is fixed or punched on floor it is fixed or
It punches and fixes on wall, integraty can be destroyed in this way, influence beauty, moreover, if wall and ground are all ceramic tiles,
It is difficult to punched above, meanwhile, destroy the integrality on wall or ground, a kind of realized using screw thread self-locking function can be with
The parked door hinge of meaning angle can solve the problems, such as.
Invention content
To solve the above-mentioned problems, effect of the present invention by compression spring, the self-lock ability using screw thread, by compression spring and screw thread
It is combined among door hinge, does not destroy door body, wall and the integrality on ground, can realize that any angle of door is electrodeless and stay
Stop.
The technical solution adopted in the present invention is:
It is described it is a kind of using screw thread self-locking function realize can arbitrarily angle parked door hinge include mainly hinge ontology and
Fixing device, hinge ontology include mainly sliding block, hexagonal socket nut I, connecting rod, fixed hinge, guide rail, central shaft, catch, locking
Hold-doun nut, left-handed mobile nut, compression spring, dextrorotation movement nut, rotary hinge, fixing device include mainly shell, interior hexagonal
Bolt, hexagonal socket nut II, pressure plate, fixed plate, hinge fix shell, and hinge ontology connects with fixing device for bolt and nut
It connects, the both ends of central shaft are rectangular step axis and are matched with the rectangular opening at rotary hinge both ends have spiral shell on rectangular step axis
Line, rotary hinge both ends are provided with slot and with catch dimensional fits, the screw-thread fit being locked on nut and rectangular step axis
And catch can be compressed, central shaft can be rotated together with rotary hinge, on the rear axis of central shaft both ends rectangular step respectively
With left hand thread and right-handed thread, the length and screw pitch of left hand thread and right-handed thread are equal, and compression spring is placed on outside central shaft
The stage casing enclosed, left-handed mobile nut screw in respectively from central shaft both ends with dextrorotation movement nut and closely abut the two of compression spring
End, and make compression spring pre-pressing;Left-handed mobile nut is respectively connected with sliding block with dextrorotation movement nut by hexagonal socket nut I, connecting rod,
Two sliding blocks merge with guide rail matching to be only capable of enough along guide rail longitudinal sliding motion, guide rail and fixed hinge one, when enabling drive center
When axis rotates, passing through screw-driven so that left-handed mobile nut can only make axial translation with dextrorotation movement nut, to
Left-handed mobile nut is set to move nut progressive ground compression press spring with dextrorotation, under the pressure effect of compression spring so that left-handed mobile spiral shell
Screw thread in cap and dextrorotation movement nut generates enough self-lockings, realizes that the random angle of door is parked.Since screw thread has well
Self-lock ability, when stop motion, door is to realize stopping by the self-locking function and axial compression spring tensile force of screw thread
Purpose when door is by certain external force, still may remain in stationary state under the action of the elastic force of compression spring, appoint to reach
Anticipating, angle is parked and the requirement of remains stationary state.
The beneficial effects of the invention are as follows:
It is of the invention novel in design practical, among compression spring and screw thread are combined to door hinge, door body, wall and ground are not destroyed
The integrality in face can realize that any angle of door is electrodeless parked, and the invisible compression spring of appearance and screw thread, avoid in door
Above, punching fixes a door-inhale and influences beauty on floor or on wall, door can be prevented to be automatically closed, effect is good.
