Abstract

The utility model relates to a stepless positioning joint which is a joint used on components such as a door, a window, a case cover, etc., belonging to the accessories of building components and furniture components. A spring is arranged inside an annular sleeve on middle part of the hinge plate of the stepless positioning joint, and a movable impeller assembly and a fixed impeller assembly are symmetrically arranged on both sides of the spring; the impeller surfaces of the movable impeller assembly and the fixed impeller assembly are coincident; the stepless positioning joint is fixed and assembled into a whole by a pin axis passing through the centre hole of the hinge plate, the spring, the movable impeller assembly and the fixed impeller assembly. The utility model can simplify the structures of the building components and the furniture components, and the utility model has the advantage of reliable positioning.

Description

Stepless locating hinge

The utility model is a used hinge on the members such as door, window, case lid, belongs to the accessory in building, the furniture member.

The location of existing door, window and various cover plates is to utilize hook or pin to locate, and the aperture size of adjustment doors, window and lid is used inconvenient arbitrarily.Designed a kind of self-return, stepless locating hinge scheme at Chinese patent CN85204362U, CN85200314U in recent years, but wherein most structure is complicated, processing is inconvenient.Though Chinese patent CN85203801U structure is simpler, but certain shortcoming is arranged, lay two oval ripple sheets that coincide mutually or claim friction plate at the axle core place of this hinge, realize any location by means of the resistance between corrugated plate, but this structure bounces two corrugated plates by the hard pressure that squeezes round about when switch door, window, too tight if two wave plates coincide, then resistance is bigger when switch door, window, because two corrugated plate direct friction, corrugated plate weares and teares easily, and the life-span is not long.The too pine if two corrugated plates coincide, resistance is less, may just be difficult to reach random positioned purpose by unexpected external force displacement.

The purpose of this utility model designs the locating hinge of a kind of stepless location and dependable performance, is used for door, window or case lid, replaces hook or mortise lock, arbitrarily the aperture of adjustment doors, window and cover plate.

In order to finish the purpose of this utility model, adopt following technical scheme: in the annular cover of the hinge plate middle part of hinge, adorn a spring, adorn to the spring bilateral symmetry moving, standing wave wheels that one group of corrugated surface coincide mutually.Moving impeller end has a key shape projection and hinge plate middle part annular cover pine to join, and the standing wave wheel end also has key shape projection, with hinge plate lower annular cover close-fitting.Pass hinge plate, spring, moving impeller and standing wave by bearing pin and take turns the centre bore of each parts and fix, be assembled into stepless locating hinge.

Embodiment of the present utility model: described in conjunction with the accompanying drawings.

Fig. 1 is stepless locating hinge schematic diagram

Fig. 2 is standing wave wheel elevation

Fig. 3 is standing wave wheel lateral view

Fig. 4 is moving impeller elevation

Fig. 5 is moving impeller lateral view

As shown in Figure 1, spring 10 is contained in the hinge plate 7 middle parts annular cover 11, in the bilateral symmetry of spring 10 moving

impeller

4 and 6 and standing wave wheel 3 and 9 are housed, the corrugated that impeller was taken turns and moved to the standing wave of both sides matches, moving impeller 4 and an end of 6 have

projection

12 and 5 to overlap 11 pines with hinge plate middle part annular respectively to join, standing wave wheel 3 and 9 one ends have equally respectively

projection

2 and 8 and the hinge plate lower annular overlap 13 close-fittings, the structure of promptly moving

impeller

4 and 6, standing wave wheel 3 and 9 is that an end is corrugated surface, and the other end is provided with the hollow circular cylinder of projection.Bearing pin 1 passes that hinge plate 7, middle part annular cover 11, lower annular cover 13, spring 10 and two groups are moving, the centre bore of standing

wave wheel

3 and 4,6 and 9, and each parts is formed stepless locating hinge integral body.

Two corrugateds of moving impeller and standing wave wheel coincide mutually, and the wave amplitude of its waveform, wavelength can be adjusted according to the different size and the use occasion of hinge, adopt sawtooth waveforms, sine to involve asymmetric waveform and all can.

Open and close the door, when window, lid, moving impeller corrugated surface moves along standing wave wheel corrugated surface, because spring action, when moving to crest, trough place, to lift, press down on moving impeller is automatic, resistance is little, start light, laborsaving, when location spring that the corrugated surface of two impellers is coincide is consistent, resistance is bigger, not reason wind-force or other unexpected external force and be shifted, and the location is reliable.

The utlity model has following advantage and good effect:

A. door, window, cover plate do not need hook, latch can realize any stepless location, simplify the structure of building and furniture member. B. owing to the elastic force effect, resistance is little during switch gate, the starting Portable power saving, and two corrugateds coincide unanimously during the location, and resistance is big, and the location is reliably. If c. meet more careless External Force Acting, door, window, closing of lid also are to move along ripple, and be slowly mobile, can not damage because of bump.

Claims

1, a kind of stepless locating hinge of forming by hinge plate and bearing pin, it is characterized in that being provided with spring 10 in the hinge plate 7 middle parts annular cover 11, spring 10 bilateral symmetry are equipped with moving impeller 4 and 6 and standing wave wheel 3 and 9, two groups of corrugated surfaces moving, the standing wave wheel match, hinge plate 7, spring 10, moving impeller 4 and 6 and standing wave wheel 3 and 9 fix by the bearing pin that passes centre bore, be assembled into one.

2, stepless locating hinge according to claim 1, it is characterized in that moving impeller 4 and 6 and the end face of standing wave wheel 3 and 9 be corrugated, the other end is provided with the hollow circular cylinder of projection.

3, stepless locating hinge according to claim 1 and 2 is characterized in that the corrugated surface ripple that moving impeller and standing wave wheel match can be zig-zag, sinusoidal waveform and asymmetric waveform.
