Abstract

The utility model discloses a multifunctional spring hinge, which comprises a doorframe hinge and a door leaf hinge. An upper tube and a lower tube are fixed on the doorframe hinge; a middle tube is fixed on the door leaf hinge; the upper tube, the middle tube and the lower tube are connected coaxially, and an axis is a clutch; the clutch is provided with an outer sleeve, a middle sleeve and a mandrel which are movably connected with the clutch; a torsional spring is arranged inside the middle tube; one end of the torsional spring is fixedly connected with the middle sleeve in the clutch, and the other end thereof is fixedly connected with a torsional spring seat which is fixedly connected with the doorframe hinge through a locating stud; a hexagon head is arranged at the outer end of the torsional spring seat. When turning under an external force, the door leaf hinge is connected with or separated from a spring through a clutch mechanism to realize the door stopping function after opening a door, the reference point of the stopping location is adjustable, the door can be closed automatically, and the speed can be adjusted, so that the door opening and the door closing are convenient; the multifunctional spring hinge has the advantages of simple structure and perdurable use, eliminates the oil leak phenomenon fundamentally, and is widely applicable.

Description

The multi-function spring hinge

Technical field

The utility model relates to a kind of multi-function spring hinge.

Background technology

Existing in the market spring hinge is in the body of hinge torsionspring to be installed, and relies on manpower to tighten the torsionspring energy storage when opening the door, and when the power of opening the door was cancelled, torsionspring released energy, and door leaf cuts out immediately automatically.During actual the use, after opening the door, usually need door and stop state, and the deficiencies in the prior art part to be the door that needs after opening the door stop state can't control automatically, also can't regulate the speed of closing the door, and that artificial prevention is closed the door automatically is pretty troublesome, make troubles to use.Also has a kind of automatic door closing hinge on the market with location and adjustable speed, this hinge is constituted by spring hinge and Speed regulating hinge, spring hinge is a spring for accumulating energy when opening the door, the spring generation door closing force that releases energy at closing time, Speed regulating hinge is to utilize plunger and flow speed control valve to produce damping by hydraulic oil to adjust the speed of closing the door, spring hinge must produce greater than the Speed regulating hinge damping force in other words just door closing force, reach the effect of closing the door of anticipation again through the release of Speed regulating hinge qualification spring force, its deficiency is a complex structure, the precision prescribed height of Speed regulating hinge own, difficulty of processing is big, processing and assembling difficulty, also will often regulate in the use, long oil leakage phenomenon in addition of time is again because the damping action of Speed regulating hinge, the door closing force of spring will overcome damping force just can make door close, make the torsionspring mounting torque strengthen the application life of having reduced spring, price height.

Summary of the invention

The purpose of this utility model provides a kind of multi-function spring hinge, be provided with door after this hinge opens the door and stop function, and the off-position control point is adjustable, and this hinge is closed the door automatically, and adjustable-speed, and it is simple in structure, and is easy to use.

The technical solution of the utility model is: the multi-function spring hinge, comprise the doorframe page or leaf, the door leaf page or leaf, be fixed with pipe on the doorframe page or leaf, following pipe, fixing middle pipe on the door leaf page or leaf, it is characterized in that: go up pipe, middle pipe, under manage coaxial connection, this axle is a clutch, this clutch has the overcoat of flexible connection, middle cover, mandrel, in put and be provided with cross-drilled hole, overcoat is provided with hole or the arc groove corresponding with cross-drilled hole with mandrel, rolling element be contained in the cavity that cross-drilled hole forms when relative with hole that puts or arc groove outward be contained in hole on cross-drilled hole and the mandrel or the cavity of arc groove composition when relative in, and rolling element and cross-drilled hole slide assembling part divide greater than rolling element and hole or arc groove slide assembling part branch, the mandrel of clutch and doorframe page or leaf are connected, the overcoat of clutch and door leaf page or leaf are connected, in the middle pipe torsionspring is housed, the middle cover of torsionspring one end and clutch is connected, and the other end and torsionspring seat are connected, and the torsionspring seat is connected by alignment pin and doorframe page or leaf.Described torsionspring seat outer end is provided with turret head.The cross-drilled hole that puts in described, quantity are one or more, and a plurality of cross-drilled holes are in the axial or arranged radially of middle cover, and overcoat and mandrel are provided with and corresponding hole of middle cover cross-drilled hole or arc groove.The rolling element that is contained in the cavity is one or more steel balls or roller.

Present technique is when door leaf page or leaf and doorframe page or leaf closure (closing the door) state, and the overcoat of clutch is connected by rolling element with middle cover.When action was opened the door in the enforcement of turning door leaf page or leaf, the active force that opens the door promoted rolling element by the overcoat of middle pipe, clutch, made in the rolling element drive and overlapped with changeing, and made the torsionspring energy storage that is connected with middle cover simultaneously.When the action of opening the door of door leaf page or leaf turns to the door of setting when stopping the control point, both overcoat, middle cover rotated, when making rolling element run into hole on the mandrel or arc groove, overcoat continues to promote rolling element just makes rolling element be rolled to middle overlapping in the cavity of forming with mandrel, this moment, clutch outer was separated with middle cover, and both overcoat separated with torsionspring.Therefore during the open and close door, the door leaf page or leaf is when setting door and stop the front, control point, and losing external force can close the door automatically, and the door leaf page or leaf loses external force when door stops the back, control point setting, and can make door leaf be parked in the position that opens or closes.And both can change a position of stopping the control point to different angles by hole or the arc groove of regulating on the mandrel.Present technique is provided with turret head in torsionspring seat outer end, uses inner hexagon spanner to rotate turret head, can regulate the moment of torsion of torsionspring, realizes regulating the door closing force and the speed of closing the door.Adopt the hinge of a plurality of present technique to be used in combination, or be used in combination with common spring hinge, be installed on the same door, the door of present technique hinge is stopped the control point and is located at the diverse location that opens the door respectively, at closing time, each spring adds the action of closing the door in different angles, be time-delay and make a concerted effort to close the door, and it is adjustable to delay time.Therefore the advantage of present technique is: be provided with door after opening the door and stop function, and the off-position control point is adjustable, comparing with existing spring hinge has increased function, makes the switch door more convenient.Present technique has the adjustable-speed function of closing the door automatically and close the door, and is compared with prior art simple in structure, and oil leakage phenomenon has fundamentally been eliminated in manufacturing, easy for installation, uses durable, applied widely.
