China national Department of Intellectual Property is called the utility model patent of " blind hinge " in a name of notice of authorization on the 26th December in 2007, notice of authorization number is CN200996238Y, a kind of blind hinge is disclosed in this utility model patent manual, hinge bodies one end links to each other with doorframe, the hinge bodies other end links to each other with door leaf, the hinge bodies that links to each other with doorframe is provided with rotating shaft, rotating shaft is located on the hinge seat in the doorframe, described hinge bodies is formed by two sections, one section links to each other with doorframe, another section links to each other with door leaf, two sections hinge bodies flexibly connect between two sections hinge bodies, are provided with the circular-arc track that is used to relatively move between two sections hinge bodies, owing to can relatively move along circular-arc track, the entire length of hinge bodies can be stretched in the switching process of door, makes the blind hinge of this utility model can realize 180 ° of unlatchings.But the structure of two sections hinge bodies of this employing, wherein one section hinge bodies slippage in the guide groove of another section hinge bodies inside, and ball is located at the both sides up and down of hinge bodies, apparently, the ball grooves of ball is set in the both sides up and down of hinge bodies, and this not only makes manufacture craft complicated more, and production and processing bothers more, install in addition and change also inconvenience, structure is also stable inadequately.
The utility model content
Problem to be solved in the utility model just provides a kind of blind hinge rational in infrastructure, easy to assembly, simplifies production technology, the cooperation of optimizing structure, reliability, stability and the practicality of raising hinge.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of blind hinge, comprise the brace that links to each other with door-plate, be located on the brace hinge casing and by the rotating shaft switching interior spiral arm on doorframe, interior spiral arm is provided with circular-arc slippage section, in hinge casing, be provided with the slippage guide frame, it is characterized in that: described slippage guide frame comprises the circular-arc gathering sill that laterally is located at the hinge casing inboard and the roller in gathering sill of vertically transferring, and the slippage section of interior spiral arm is inserted between gathering sill and the roller and by the spacing horizontal slippage in gathering sill of roller.
Further, the medial surface of described gathering sill laterally is provided with ball grooves I, the closed at both ends of ball grooves I, in ball grooves I, be provided with plurality of balls, ball is provided with the back-up ring that parcel connects ball, the lateral surface of the slippage section of interior spiral arm laterally is provided with the corresponding ball grooves II with ball grooves I, and ball grooves I, ball, end ring and ball grooves II form slide construction.This slide construction is similar to 1/4 bearing, reduces friction and loss, making opens the door close the door more laborsaving.
Further, be not in contact with one another between the lateral surface of the slippage section of the medial surface of described gathering sill and interior spiral arm.
Further, described brace is fixedlyed connected by threaded fastener with hinge casing.
After adopting technique scheme, the utlity model has following advantage: structure is simpler, the cooperation of optimizing structure, make assembling convenient, improve the reliability and stability of hinge, reduce the contact area between hinge casing and the interior spiral arm, reduce friction and loss, making opens the door closes the door more laborsavingly, has also prolonged application life of hinge accessory, improves the practicality of hinge.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
The internal construction schematic diagram that Fig. 1 overlooks for a kind of embodiment of the utility model;
Fig. 2 is an A place sectional drawing among Fig. 1.
The specific embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 1 to 2, a kind of blind hinge, comprise the brace 1 that links to each other with door-plate, the interior spiral arm 3 that is located at the hinge casing 2 on the brace 1 and transfers on doorframe by rotating shaft 4, interior spiral arm 3 is provided with circular-arc slippage section 31, laterally be provided with circular-arc gathering sill 21 in hinge casing 2 inboards, vertical switching has two rollers 5 that are circular-arc distribution, the slippage section 31 of interior spiral arm 3 to be inserted between gathering sill 21 and the roller 5 and by roller 5 spacing horizontal slippages in gathering sill 21 in gathering sill 21.Medial surface 22 at hinge casing 2 laterally is provided with two ball grooves I23, the closed at both ends of ball grooves I23, in ball grooves I23, be provided with plurality of balls 6, same the interior ball 6 of ball grooves is provided with the end ring 61 that parcel connects ball 6, lateral surface 310 at interior spiral arm 3 laterally is provided with two and the corresponding ball grooves II33 of ball grooves I23, and ball grooves I, ball, end ring and ball grooves II form a slide construction that is similar to 1/4 bearing.Brace 1 and hinge casing 2 are fixedlyed connected by threaded fastener, as screw and bolt and nut.
In the foregoing description, the upper and lower surface of the slippage section 31 of interior spiral arm 3 contacts guiding with the upper and lower surface of gathering sill 21, be not in contact with one another between the external surface 310 of the medial surface 22 of hinge casing 2 and the slippage section 31 of interior spiral arm 3, reduce the contact area between hinge casing and the interior spiral arm like this, reduce friction and loss, making opens the door closes the door more laborsavingly, has also prolonged application life of hinge accessory, improves the practicality of hinge.The quantity of roller 5 and ball grooves I23, ball grooves II33 changes setting as required in addition.Be worth to propose, the institute of gathering sill 21 is circular arc and should be circular arc with 31 of the slippage sections of interior spiral arm 3, and with roller 5 distribute to be circular arc concentric.
