Abstract
The utility model discloses a kind of primary and secondary hinges, including the first hinge and the second hinge, first hinge and the second hinge warp beam sleeve are mounted on same mandrel, first hinge surrounds the second hinge or the first hinge and is arranged above and below with the second hinge point, and the thickness of the first hinge and the second hinge close to mandrel one end to far from mandrel one end from successively decreasing.The hinge has regulatory function, even if having for side, if the doorframe of deflection door leaf can be thoroughly closed with doorframe, offers convenience to using.
Description
Technical field
The utility model is related to a kind of hinges, and in particular to a kind of primary and secondary hinge.
Background technology
Hinge is two parts of attached article and can be allowed to movable component.Conventional hinges are through at same by opposite two panels
Mandrel institute is at for cupboard door, window, door etc., when use needs the prefabricated groove on doorframe and door leaf, and the two panels of hinge is distinguished
In groove.Primary and secondary hinge is also to be made of two hinges, but the two hinges point are arranged above and below and are through at same core
Axis, or female hinge surround blades, without the state being affixed when two hinges are closed up in conventional hinges.Primary and secondary hinge
When using on door, directly hinge can be fixed on doorframe or door leaf by the screw hole in hinge, without prefabricated recessed
Slot.Usual door is under the state that closes, plane where door leaf and plane degree in a vertical angle where part of the doorframe equipped with hinge, at this time
Two hinges of hinge are in closed configuration.But when doorframe and door leaf make, since production process is not absolutely accurate,
Plane where part of the doorframe equipped with hinge will produce certain deflection sometimes, and door is caused just to make before closing at door leaf and doorframe
In vertical angle, cause thoroughly to be closed to continue to close the door at this time, then door leaf will generate the frame face equipped with hinge of doorframe and squeeze
Pressure, while door can be caused to be not easy thoroughly to be closed by reaction force, or be extremely easy to make a disengagement.
Utility model content
The purpose of this utility model is to provide a kind of primary and secondary hinge, which has regulatory function, even if having for aforementioned
The doorframe of flaw can also be such that door leaf is thoroughly closed with doorframe, offer convenience to using.
To achieve the goals above, the utility model adopts the following technical scheme that：
A kind of primary and secondary hinge, including the first hinge and the second hinge, the first hinge and the second hinge warp beam sleeve are mounted on same
On one mandrel, the first hinge surrounds the second hinge or the first hinge and is arranged above and below with the second hinge point, which is characterized in that described
The thickness of first hinge and the second hinge close to mandrel one end to far from mandrel one end from successively decreasing.
Preferably, the cross section vertical with mandrel of first hinge is isosceles trapezoid, and the second hinge is hung down with mandrel
Straight cross section is isosceles trapezoid.
Preferably, the bottom length of the isosceles trapezoid is 2.5 ~ 3.2 millimeters, and upper bottom length is 1.5 ~ 2.2 millimeters.
Preferably, bearing is cased on the mandrel, the bearing is located at the axle sleeve and described second of first hinge
Between the axle sleeve of hinge.
In the technical solution of the utility model, the first hinge and the second hinge are positioned on doorframe and door leaf respectively, in door
During fan is closed, the inclined-plane of the first hinge and the second hinge both sides can be adjusted, i.e. the frame for installing hinge
Towards tilted, the case where to which door leaf is less than 90 degree with frame face angle after so that door is thoroughly closed, since two hinges are by mandrel
End is gradually thinning outward, will not occur previous door leaf and doorframe after door is thoroughly closed to the case where extruding in this way, thus
Door is set smoothly to be closed.
Description of the drawings
Fig. 1 is the utility model structure diagram.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in Figure 1, this primary and secondary hinge includes the first hinge 1 and the second hinge 2, the two is respectively connected with axle sleeve, and passes through
Mandrel 9, which is worn, to connect together.There are screw holes 3 in first hinge 1, and internal there are gaps can accommodate the second hinge 2, to formation pair
The encirclement of second hinge 2, there are screw holes 4 for the second hinge.The first hinge can also be made to be located at the mandrel first half, and the second hinge position
In mandrel lower half, respectively rotates, do not interfere with each other around mandrel, it will not can two hinge phases as conventional hinges when closing up
Patch.Thickness of first hinge close to mandrel one end is more than the thickness far from mandrel one end, and gradually equal from one end to the other end
Even variation, one end thickness that the second hinge is also proximate to mandrel gradually reduce to one end far from mandrel.For this purpose, the first hinge 1
Perpendicular to the cross section of mandrel can be isosceles trapezoid 5 with the second hinge 2（The cross section does not take in the first hinge inward flange and
The part of two hinge outer edge irregular shapes）, it is longer bottom 7 close to one end of mandrel, separate one end is upper bottom 6.
General bottom length changes between 2.5 ~ 3.2 millimeters, can such as take 3 millimeters, upper bottom length is between 1.5 ~ 2.2 millimeters of millimeters
Variation, can such as take 2 millimeters.Bearing 8 is cased on mandrel 9 between the first hinge 1 and the second hinge 2, bearing 8 can make
One hinge and the rotation of the second hinge are more flexible.
In use, the first hinge 1 can be installed to by screw hole 3 on the side frame face of doorframe outward with mandrel, second
Hinge 2 is installed to by screw hole 4 on the side of door leaf, since hinge is thinning from mandrel to hinge edge, in this way in door leaf and door
When frame is closed, allows the frame face angle equipped with hinge of door leaf and doorframe that will not generate extruding force when being less than 90 degree, be as a result,
Make when producing doorframe, the frame face of the installation hinge of doorframe there are some inclinations in time so that when door leaf the is closed and frame face of doorframe
Angle is less than 90 degree, also because the above-mentioned adjusting of hinge is without will produce reverse extrusion power, so as to smoothly close the door.
The present embodiment is the explanation conceived to the utility model and realized, is not intended to limit it, in this reality
With under novel design, without the technical solution that substantially converts still in protection domain.
