Abstract

The utility model provides a door hinge, including wearing out fixed door (60) and being equipped with first back clamping piece (12) that first preceding clamping piece (11) of fluting (16) combine, wear out clamping piece (22) behind second that clamping piece (21) combine before dodge gate (70) and the second that is equipped with fluting (26), place clamping piece (12) behind first back and the second in the framework of acceping (13, 23) of clamping piece (22), install in cross fastening piece (31), drive biax synchronous pivoted gear train (40) is made in dodge gate (70). The door has the characteristics that the door can be opened inwards, outwards and inwards no matter whether the movable door (70) is internally or externally provided with barriers, and the maximum door opening angle and the maximum rotating angle of 360 degrees can be realized.

Description

The door hinge

Technical field

The utility model relates to a kind of hinge, but particularly a kind of twin shaft rotates the door hinge of 360 degree synchronously.

Background technology

Traditional door hinge is just carried out fixed gate and dodge gate by a fixed axis hinged, not running part.This connected mode makes that the rotating angle of dodge gate is very limited, probably about 180 degree; And the seam crossing space of this door hinge is bigger, has the shortcoming of leaking.

The utility model content

The technical problems to be solved in the utility model is, a kind of door hinge simple in structure, that the anglec of rotation is big is provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of hinge, comprise and pass first rear jaw that fixed gate combines with the first preceding intermediate plate that is provided with fluting, pass second rear jaw that dodge gate combines with the second preceding intermediate plate that is provided with fluting, be placed on the spider in the framework of accommodating of described first rear jaw and second rear jaw, be installed in the described spider, drive described dodge gate and make the gear train that twin shaft rotates synchronously.

The described gear train of above-mentioned door hinge comprises by fixed axis and described opening of accommodating framework two fixed gears of inlay card location and two travelling gears that drive described dodge gate rotation respectively with described two fixed gears engagement mutually.

Above-mentioned door described first rear jaw of hinge and described second rear jaw are provided with screw, be provided with screw equally on the intermediate plate before the intermediate plate and second before corresponding first, and by screw the described first preceding intermediate plate and first rear jaw are fixed on the described fixed gate, the described second preceding intermediate plate and second rear jaw are fixed on the described dodge gate.

The described gear train of above-mentioned door hinge also comprises the recovery spring that is connected with described fixed gear.

Compared with prior art, the utility model door hinge is made twin shaft by the gear set drive dodge gate and is rotated synchronously, no matter have inside and outside the dodge gate whether obstruction is arranged, open in can realizing, external-open, interior external-open, and realize maximum open angle, the maximum rotation angle is the characteristics of 360 degree.

The specific embodiment

Below in conjunction with accompanying drawing door hinge of the present utility model is described in further detail.See also Fig. 1 to Fig. 4, intermediate plate 11, the second preceding intermediate plate 21, first rear jaw 12, second rear jaw 22, spider 31 and gear train 40 before the utility model door hinge comprises first.Described first rear jaw 12 and second rear jaw 22 are provided with accommodates

framework

13,23 and

screw

14,24, described first rear jaw 12 accommodate framework 13 and screw 14 can pass fixed gate 60, with first before the screw 17 of intermediate plate 11 cooperate to combine and be fixed on the described fixed gate 60 by screw 50; Described second rear jaw 22 accommodate framework 23 and screw 24 can pass dodge gate 70, with second before the screw 27 of intermediate plate 21 cooperate to combine and be fixed on the dodge gate 70 by screw 50.Corresponding with the described

framework

13,23 of accommodating, before described first, be provided with fluting 16,26 before the intermediate plate 11 and second on the intermediate plate.Described spider 31 is a hollow structure, is placed on the accommodating in the

framework

13,23 of described first rear jaw 12 and second rear jaw 22.Described gear train 40 is installed in the described spider 31, and can drive described dodge gate 70 and make twin shaft and rotate synchronously.Described gear train 40 comprises two fixed gears 42 that are connected with second rear jaw 22 with first rear jaw 12 respectively by fixed axis 41, and be meshing with each other and respectively with the travelling gear 43 of described two fixed gears 42 engagements.As shown in Figure 5, described gear train can also be provided with and recover spring 44, and described recovery spring 44 can be connected with fixed gear 42.When dodge gate 70 is not fastened, can utilize the elastic restoring force of recovering spring 44 to make dodge gate 70 fasten, promptly with fixed gate 60 in line.

During assembling, earlier travelling gear 43 and fixed gear 42 are placed in the spider 31, and it is meshing with each other; Then by fixed axis 41 inlay cards in the opening of

accommodating framework

13,23 15,25 of first rear jaw 12 and second rear jaw 22, with fixed gear 42 location; Then with the screw 14 of first rear jaw 12 and accommodate framework 13 pass fixed gate 60, with the screw 24 of second rear jaw 22 with accommodate frame and wear 23 and go out dodge gate 70, again by screw 50 (or bolt etc.) with intermediate plate 11 and second before first before intermediate plate 21 combine locking respectively with first rear jaw 12 and second rear jaw 22, thereby finish assembling.

When promoting described dodge gate 70, driven gear group 40 makes the transmission that is meshing with each other of the gear of gear train, and because fixed gear 42 is to be fixed on dodge gate 70 and the fixed gate 60 by two fixed axis 41 respectively, the formation twin shaft rotates, and its rotational angle can reach 360 degree, as shown in Figure 4.Thereby no matter inside and outside the dodge gate 70 whether obstruction is arranged, open in can realizing, external-open, interior external-open, and realize doing big open angle.In addition, described spider 31 is tight with cooperating of described preceding

intermediate plate

11,21 and

rear jaw

12,22, and its gap can be very little, for example reaches 0.5mm, thereby has solved the seam crossing space of door hinge, has the shortcoming of leaking.
