Abstract

A hinge device comprises a first connecting component, a second connecting component and a third connecting component. A shaft sleeve is arranged on one side of the first connecting component, and the second connecting component and the third connecting component are connected with the first connecting component via a coupled shaft. Two outer taper sleeves are fixedly combined with two ends of the shaft sleeve in a sleeving manner, two inner taper sleeves are respectively combined with the two outer taper sleeves in a tapered sleeving manner, an elastic component arranged between the two inner taper sleeves provides axial pressure, the coupled shaft penetrates through the two inner taper sleeve and matches with the same in a coupled manner, and the second connecting component and the third connecting component are respectively and fixedly connected with two ends of the coupled shaft in a fastening manner. The hinge device adopts a double-taper-sleeve friction structure to increase the contact surface of friction torque and friction force, therefore, when a door, a window or a cabinet door which is heavier or needs to bear certain external force is connected, the hinge device is capable of providing sufficient friction resistance to maintain opening angle of the door, the window or the cabinet door.

Description

A kind of hinge means

Technical field

The utility model relates to a kind of hinge joining means, especially connects door and window, cabinet door heavier or that need bear certain external force, also can keep the opening angle of door and window, cabinet door simultaneously well.

Background technology

In the prior art, particularly in some door and windows that spin upside down, cabinet door, need to provide the hinge means of frictional resistance to connect, to keep the opening angle of door and window, cabinet door.Existing a kind of spring shim that is placed in admittedly in the hinge shaft sleeve by polylith of widespread usage is stuck on the circular spindle of hinge, and the frictional force that is produced between the axle keeps the opening angle of door and window, cabinet door.

This hinge means is because the limited space of axle sleeve, the diameter of axle of axle is less relatively, spring card is the ring spacer that an end has opening, though the spring shim of stack polylith, but the frictional force distance on the axle surface is less, the contact surface that produces frictional force is also less relatively, the frictional force of Chan Shenging is also less relatively therefrom, so in this hinge means, there is such technological deficiency, when connecting door and window, cabinet door heavier or that need bear certain external force, just can not provide enough frictional resistance opening angle with maintenance door and window, cabinet door.

The utility model content

Therefore goal of the invention of the present utility model is, a kind of hinge joining means is provided, even connect door and window, cabinet door heavier or that need bear certain external force, also can keep the opening angle of door and window, cabinet door well.

For realizing above purpose, the utility model hinge means, comprise first link, equal second link and the 3rd links that is connected by couple axle with first link, side at first link is provided with axle sleeve, be respectively equipped with external conical sleeve with the fastening fit of axle sleeve at the two ends of this axle sleeve, two external conical sleeves are respectively equipped with the center through hole of circular cone column, two center through hole are relative reaming setting, two inner conical drogues respectively with the center through hole tapering fit of two external conical sleeves, be provided with the elastomeric element that axial compression is provided between two inner conical drogues, two inner conical drogues are respectively equipped with center through hole, described couple axle runs through the center through hole of two inner conical drogues, and couple axle becomes interlock to cooperate with two inner conical drogues, and second link and the 3rd link are fastenedly connected with the two ends of couple axle respectively.

Described axle sleeve two ends inwall is respectively equipped with keyway, the external surface of described two external conical sleeves is respectively equipped with the protruding key that matches with keyway, two external conical sleeves are combined in the two ends of axle sleeve by key connected mode fixed cover is arranged, and the pars intermedia of axle sleeve forms shoulder hole, to limit relative the moving axially of two external conical sleeves.

Described couple axle is a non-circular shaft, be preferably square shaft, the center through hole of two inner conical drogues also is set as square center through hole ordinatedly, described elastomeric element is the compression spring, both ends of the spring places on the couple axle with two inner conical drogue adapter sleeves respectively, end at second link and the 3rd link is respectively equipped with a footstalk, the diaxon shank end portion is not provided with the square trepanning that cooperates square couple axle, two ends with couple axle securely are linked in, second link and the 3rd link are set as the two ends that relatively are connected in couple axle, be set as at the opposite side of second link and the 3rd link and be spliced into integrated, splicing place at second link and the 3rd link is provided with groove and the protruding falcon that matches respectively, makes closely to be spliced into one.

Owing to adopted technique scheme, external conical sleeve is combined on first link by the axle sleeve fixed cover, inner conical drogue links together linkedly by couple axle and splicing all-in-one-piece second link and the 3rd link, when second link and the 3rd link when first link rotates, driving inner conical drogue rotates relative to external conical sleeve, because pressing of compression spring, make the external surface of inner conical drogue closely contact with the inner surface of external conical sleeve, will produce bigger frictional resistance, thereby keep the rotational angle of rotating side connector.

The utility model is owing to adopted the structure of two-taper ferrule friction, frictional force on the contact surface of two-taper ferrule is apart from the frictional force distance on the axle surface is bigger relatively, and the contact surface that produces frictional force is bigger, therefore it is also relatively large to produce frictional force, so when connect be heavier or need bear certain external force door and window, cabinet door the time, also can provide enough frictional resistance to keep the opening angle of door and window, cabinet door.
