Abstract

The utility model discloses a positioning hinge, which belongs to the hinge device. The utility model is suitably used for keeping the definite angle when the head cover is opened such as the head cover of a refrigerator, and the front and back covers of a car. The positioning hinge can also be used on a door and window which needs to be positioned. The utility model adopts springs whose elastic forces are smaller and has the advantages of high capability, compact structure, small size, and convenient installation.

Description

Locating hinge

The utility model relates to a kind of improvement of location structure of hinge means.

Present locating hinge used on refrigerator is used the elastic force than big spring, goes to be supported and fixed on the weight of hinge upper cover, the lid breakdown is kept at an angle, the pivot center of this locating hinge and the axis of spring are the vertical configuration structure, and volume is big, and inconvenience is by dress.

The utility model obtains bigger hinge stationkeeping ability in order to overcome above-mentioned the deficiencies in the prior art, provide the power of using than little spring, and volume is little, is convenient to a kind of locating hinge by dress.

Shown in the structure accompanying drawing of the present utility model, by moving plate 1, stator 2, decide metalworks such as batter post 3, moving batter post 4, spring 5, rivet 6 and form.

The plurality of fixed hole is arranged on the upper plane of moving plate 1, and the bottom is a flat garden shape hinge shaft sleeve.The plurality of fixed hole is arranged on the lower flat of stator 2, and respectively there is an interior perforation at center, two sides, top, constitutes the fixed hinge shaft support.There is rivet hole the centre of deciding batter post 3, and an end has external tooth, and the other end is the inclined-plane; There is the shoulder through hole centre of moving batter post 4, and an end pocketed springs 5, the other end are the inclined-plane; Spring 5 two ends, the moving batter post 4 of one of each suit and decide batter post 3 contacts the inclined-plane relatively, runs through the jail of riveting afterwards with rivet 6, is assembled into flat garden shape hinge axis, Fig. 5 and shown in Figure 6.Flat garden shape hinge axis is inserted in the flat garden shape hinge shaft sleeve of moving plate 1, add compression set batter post 3, make spring 5 compressions, be pressed in the shape hinge shaft sleeve of flat garden deciding exceeding partly of batter post 3, two ends are decided the external tooth of batter post 3, be fixed to by dress in the two sides of stator 2 in the perforation, finish the assembling of locating hinge.

When the flat garden of moving plate 1 shape hinge shaft sleeve rotates, be bound to push move batter post 4 on the shape hinge axis of flat garden and produce and move, spring 5 is compressed, flat garden shape hinge shaft sleeve and decide batter post 3 and moving batter post 4 between produce frictional force, frictional force increases along with the corner of moving plate 1 and increases frictional force maximum during corner 90.Frictional force is enough to moving plate 1 is positioned on the position of needs.If will turn round moving plate 1, need reverse afterburning overcome friction that moving plate 1 is resetted.

It is as follows that the utility model compared with prior art has advantage:

With elastic force than little spring, produce bigger frictional force, obtain bigger stationkeeping ability; Axle of spring and hinge axes are same axis, compact conformation, and volume is little, is convenient to by dress.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a locating hinge structure elevation cross-sectional view;

Fig. 2 is a locating hinge structure A-A sectional drawing;

Fig. 3 is moving plate 1 structural representation;

Fig. 4 is stator 2 structural representations;

Fig. 5 is a flat garden shape hinge axis assembling schematic diagram;

Fig. 6 is a flat garden shape hinge axis B-B sectional drawing.

When locating hinge is useful in the top cover breakdown, need to keep certain breakdown angle, for example: refrigerator top cover, car front and rear covers, also can be used on the door and window that needs the location.Locating hinge identical with common hinge by dress, in order to guarantee enough big locating friction power, locating hinge be do not allow grease-added.

Claims

1, a kind of with moving plate 1, stator 2, decide the locating hinge of metalworks compositions such as batter post 3, moving batter post 4, spring 5, rivet 6, it is characterized in that:

(1) on the upper plane of moving plate 1 the plurality of fixed hole is arranged, the bottom is a flat garden shape hinge shaft sleeve;

(2) on the lower flat of stator 2 the plurality of fixed hole is arranged, there is interior perforation at center, two sides, top, and two interior perforations constitute the hinge shaft support;

(3) spring 5 two ends, the moving batter post 4 of one of each suit and decide batter post 3 contacts the inclined-plane relatively, runs through the jail of riveting afterwards with rivet 6, is assembled into flat garden shape hinge axis;

(4) in the flat garden shape hinge shaft sleeve of flat garden shape hinge axis insertion moving plate 1, the external tooth that batter post 3 is decided at two ends is fixed in the interior perforation of stator 2 two sides by dress.
