Abstract

The utility model relates to a hidden hinge, which belongs to a connecting device for door/window and is used for overcoming the problem of hinge exposal. The hidden hinge comprises two blades respectively fixed on a pair of pieces to be hinged; Wherein the two blades are hinged through at least two cranks; one end of each crank is hinged with one of the blades through a long shaft, the other end of the crank is hinged with the other blade through a short shaft, and the middle parts of all the cranks are hinged through a connecting shaft; each blade is provided with a group of slideways vertical to the contact surfaces of the two blades, and the short shaft is arranged in the slideways. A door, window or wing where the hidden hinge is applied can be conveniently and flexibly opened by 180 degree; the arrangement of the structures such as the slideways on the two blades and the short shaft in the slideways enables the hinge not to be exposed when in use, thereby not only ensuring the flatness and the throughput capacity, but also enabling the device adopting the hinge to be artistic.

Description

Built-in hinge

Technical field

The utility model relates to the interface unit of door, window etc., refers to a kind of built-in hinge particularly.

Background technology

Door, window and wing etc. mostly are to flexibly connect, realize its switching function by hinge and corresponding framework.Common hinge is made of two blades and bearing pin thereof, and a vanes fixed is in the side of door or forms, and another vanes fixed is in corresponding framework side, and door, window can rotate around bearing pin.Use the hinge of this structure, no matter door, window etc. are to open or closure state, and hinge all exposes, and not only takes up room, and influences planeness and attractive in appearance.

The utility model content

The purpose of this utility model is exactly to overcome the problem that existing hinge exposes, and a kind of delicate structure is provided, can opens 180 ° built-in hinge.

For achieving the above object, a kind of built-in hinge of providing of the utility model comprises and is used to be separately fixed at two blades treating on the hinge member.It is hinged to crank arm by at least two between described two blades.Described each end of cranking arm is hinged by major axis and a blade, and the other end of cranking arm is hinged by minor axis and another blade, and all middle parts of cranking arm are hinged by connecting axle.Described each blade offers one group of chute, and chute is vertical with the contact surface of two blades, and described minor axis is arranged in this chute.

Described connecting axle is shorter than the distance of connecting axle to minor axis to the distance of major axis.

Described blade is a stairstepping, on blade, two contacted ends of blade are provided with the major axis fixed via.Blade one side at the contact surface of two blades and minor axis place is equipped with and is used to hold described fluting of cranking arm.

Described chute is provided with limited block at the end near contact surface.

Described chute is flat.

The beneficial effects of the utility model are: use door, window, wing of this built-in hinge etc., 180 ° of unlatchings that can be convenient, flexible; The setting of two blade upper hopper chutes and interior minor axis thereof, and the setting that is used to hold the fluting of cranking arm on the blade make hinge in use can not expose, and have both guaranteed planeness and trafficability characteristic, the feasible again device good looking appearance of using this hinge.

Description of drawings

Fig. 1 is the structural representation of built-in hinge of the present utility model when opening 180 °;

Fig. 2 and Fig. 3 are the structural representation of blade among Fig. 1;

Among the figure, 1-blade (wherein: 1.1-major axis fixed via, 1.2-chute, 1.3-screw, 1.4-contact surface), 2-cranks arm, 3-connecting axle, 4-major axis, 5-minor axis.

The specific embodiment

Below in conjunction with the drawings and specific embodiments built-in hinge of the present utility model is described in further detail:

As shown in Figure 1 to Figure 3, built-in hinge of the present utility model comprises and is used to be separately fixed at two step vanes 1 treating on the hinge member.It is 2 hinged to crank arm by two between two blades 1.2 the end of cranking arm is shorter, and the other end is longer.On each blade 1, two blades, 1 a contacted end is provided with major axis fixed via 1.1, is provided with major axis 4 in it, 2 the short end of cranking arm is hinged with one of them blade 1 by this major axis 4; Each blade 1 places in this chute 1.2 along 1.2, minor axises 5 of chute that the vertical direction of two blades, 1 contact surface 1.4 offers one group of flat, can move in chute 1.2, and 2 the long end of cranking arm is hinged with another blade 1 by this minor axis 5.One end of chute 1.2 is provided with limited block, is used for the spacing of minor axis 5, makes the relative rotation of two blades 1 be no more than 180 °.Two crank arm 2 middle parts are hinged by connecting axle 3.Blade 1 one sides at the contact surface 1.4 of two blades 1 and minor axis 5 places are provided with and are used to hold described 2 the fluting of cranking arm, and can guarantee in the hinge through process, crank arm not exceed blade and take up space, and reach stealthy effect.

Operating principle of the present utility model is as follows:

As shown in Figure 1, the schematic diagram that this state is this hinge when opening 180 °, this moment minor axis 5 to be positioned at chute 1.2 also limited near an end of two blades, 1 contact surfaces 1.4; When two blades 1 simultaneously when connecting axle 3 upwards overturns, the two 2 also upwards upsets of cranking arm, minor axis 5 moves along the other end of chute to

blade

1,2 the long end of cranking arm moves and enters in the fluting of blade 1 side along with minor axis 5.When the contact surface 1.4 of two blades 1 is fitted fully, a side that 2 long end enters blade fully that two crank arm, promptly hinge is closed fully, use the door, window, wing etc. of this hinge to close, and hinge does not expose.

2 the quantity of cranking arm in the present embodiment is two, and in actual applications, cranking arm 2 can also have three or more, and its connected mode is cranked arm one of 2 identical with above-mentioned two separately.Blade 1 also can be other shape, above-mentionedly cranks arm 2 and parts such as major axis 4, minor axis 5 as long as can hold on the one hand, is convenient on the other hand be fixed on and treats to get final product on the hinged parts.2 the concrete number of cranking arm and arrange and the concrete shape of blade 1 is not subjected to the restriction of present embodiment.
