Described upper jointed shaft 3 and the surface of lower jointed shaft 4 is provided with key teeth 33, with the keyway being arranged in the second positioning sleeve Coordinate so that upper jointed shaft 3, the positioning sleeve 21 of lower jointed shaft 4 and second make synchronous axial system.

Described upper directive wheel 32 is arranged on the top of piston rod 34 of buffer 31.

Described spring drive 41 includes guide wheel shaft 43 and spring 44, and spring 44 and guide wheel shaft 43 are arranged on lower hinge In spindle 4, lower directive wheel 42 is arranged on the top of guide wheel shaft 43, and the downward driver 63 all the time of guide wheel shaft 43 is promoted by spring 44 Move in direction.

The described upper surface of upper driver 62 is symmetrically arranged with two V-grooves 621 to cave inward, passes through between two V-grooves Transition platform 622 connects.

The described lower surface of lower driver 63 is provided with reseting groove 631, and the section of reseting groove 631 is in " √ " shape.

90 ° of settings of axial offset of described upper directive wheel 32 and lower directive wheel 42.

Operation principle：

As shown in Figure 1, 2, 3, when hinge is closed, lower directive wheel drives under entering under the supporting role of spring The bottom land of the reseting groove 631 of dynamic device 63, and upper directive wheel 32 is then located at the groove top of V-groove so that buffer is in the shape of compression State.

As shown in Figure 4,5, when hinge is opened, the first hinge and the second hinge relative motion so that, upper directive wheel is slow Rush under the reset response of device, moved from the groove top of V-groove to trench bottom direction.And lower directive wheel is extruded on the slope of reseting groove and made Moved downward under, so as to compression spring, play accumulation of energy effect when being closed to hinge.

As shown in fig. 6, when hinge is opened fully to 90 °, the groove that upper directive wheel enters V-groove is low interior, and buffer is complete Stretch out, in state to be buffered.And lower directive wheel then moves to the groove top state of reseting groove, and spring is then in maximum compression State.

As shown in Fig. 5,7, after user unclamps door-plate, hinge loses the support force of outside, springback, passes through directive wheel The lower directive wheel of axle driving moves upwards.Directive wheel active force is located on the slope of reseting groove at present for this so that on lower driver hair Deflection, so as to serve the effect of automatically reseting of hinge.Wherein, cause to hit between door-plate and doorframe in order to avoid reset speed is too fast Generation noise is hit, when resetting revolution, the cell wall of V-groove mutually extrudes the upper driver in this case with upper directive wheel, in utilization Directive wheel promotes buffer slowly to reset, under the interaction of power so that upper driver slowly rotates, so as to serve hinge The effect that automatic buffer resets.

Into a step, wherein in order to make upper and lower directive wheel can only be along axe movement so that upper and lower directive wheel with it is upper, The V-groove and reseting groove of lower driver, which mutually extrude, acts power, and buffer 31 is provided with by upper connecting shaft 35 in this case Upper directive wheel 32 is pressed on the upper surface of driver 62, upper connecting shaft 35 extend into be arranged on it is upper on the cylinder of jointed shaft 3 In guide groove 36 so that upper directive wheel 32 can only axially move along upper guide groove 36.And on spring drive 41 under Connecting shaft 46 is provided with lower directive wheel 42, and lower directive wheel 42 is pressed on the lower surface of lower driver 63, and lower connecting shaft 46 extends into It is arranged in the lower guide groove 47 on the lower cylinder of jointed shaft 4 so that lower directive wheel 42 can only make axial fortune along lower guide groove 47 It is dynamic.

Wherein it should be noted that：Buffer and spring drive in this case are arranged on upper jointed shaft and lower jointed shaft It is interior, play to buffer and the effect of spring drive radial positioning, avoiding active force from directly acting on positioning sleeve influences it and make Use the life-span.Meanwhile connected between guide collar and upper driver and lower driver by plane bearing, avoid directly contacting between the two and rub Wipe so that this hinge can stablize quiet operation.

Summary, resetting means its buffering dress is provided with the jointed shaft of hinge compared with conventional art, in this case Put so that hinge can automatic buffer reset, while requirement is met, avoid conventional reset hinge from easily causing door-plate Noise caused by mutually being hit with doorframe.In addition, unique activation configuration and buffer unit and resetting means are utilized in this case Coordinate, traditional torsion spring structure is replaced using spring, it is more stable when spring moves than torsion spring on the premise of its elastic force is ensured Efficiently, movement range is also relatively fewer, the axis coinciding of the direction of motion and door-hinge of buffer and spring, therefore above-mentioned portion in addition Part is without protruding outside hinge so that this structure is more compact compact, so as to make the door and window profile for installing this hinge more attractive in appearance.

The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.
