A kind of locate mode inner hinge, this inner hinge comprises determines hinge and dynamic hinge, determines to be connected by Rectangular Spring, rotating shaft between hinge with dynamic hinge; Spring is used for the adjustment of rotating shaft pressure, thus determines the detent force between hinge and dynamic hinge.Its structure design main points are that described dynamic hinge comprises the first dynamic hinge and the second dynamic hinge, first dynamic hinge and the second dynamic hinge are connected as a single entity by chapiter screw, one side of junction is by rotating shaft and determine chain connection, the two ends of rotating shaft are respectively equipped with protruding square head, and square head inserts four square holes of junction described in the first hinge and the second hinge respectively; The middle side of rotating shaft is provided with flat key groove, determines to be provided with guide, Rectangular Spring, sealing screw in hinge successively, and guide is offseted by the flat key groove of Rectangular Spring and rotating shaft.Thus by regulating sealing screw, regulate Rectangular Spring to be indirectly applied to the pressure on rotating shaft flat key groove by guide; The square head of rotating shaft ensure that rotating shaft fixing on dynamic hinge, and namely rotating shaft flat key groove direction is fixing.
Described rotating shaft is at least provided with one group of adjacent flat key groove, and guide is offseted by a wherein flat key groove of Rectangular Spring and rotating shaft.By the design of adjacent flat key groove, control two Plane Angle, ensure the orientation angle controlling to be installed on this inner hinge of door-plate by two Plane Angle; Meanwhile, the design of many flat keys groove and many Plane Angle, makes this inner hinge be applicable to the location of multi-angle.
Describedly to determine in hinge three through holes in " T ", rotating shaft is arranged to be determined in two relative through-hole passage of hinge, and guide, Rectangular Spring, sealing screw are arranged to be determined in another through-hole passage of hinge; Be respectively equipped with sealing ring in the first dynamic hinge at rotating shaft two ends and the second dynamic hinge, namely determine the side that two relative through holes of hinge are positioned at the first dynamic hinge and the second dynamic hinge connection.Said structure ensure that rotating shaft, guide, Rectangular Spring, sealing screw respectively in dynamic hinge and the sealing determined in hinge, thus further ensures this inner hinge stability in use, prevents dust etc. to enter the use affecting this inner hinge.
Described first dynamic hinge and the second dynamic hinge are respectively in ", " font, and a side of junction is positioned at the round dot end of one end.The shape and structure of above-mentioned dynamic hinge, facilitates the inner side of this inner hinge between door-plate and installs.
The other end of the described first dynamic hinge and the second dynamic hinge is by the concavo-convex connection of voussoir, and the first dynamic hinge and second moves the plane of round dot transverse plane higher than this end of hinge.Said structure ensure that the one between the first dynamic hinge with the second dynamic hinge is connected, and meets the mounting means of inner side between door-plate further by dynamic hinge and the difference in height of determining between hinge.
The utility model reasonable in design, uses, easy to assembly, and stability, sealing, safety are good; It is suitable as locate mode inner hinge and uses, and being connected and fixed for subway door-plate ex hoc genus anne product.

Detailed description of the invention
Now by reference to the accompanying drawings, the utility model structure and use are further described.As shown in Fig. 1 ~ Fig. 5, this inner hinge comprises dynamic hinge, determines hinge 3, rotating shaft 4, guide 5, sealing screw 6 and Rectangular Spring 9, dynamic hinge comprises the first dynamic hinge 8 and the second dynamic hinge 7; Its concrete structure is: the first dynamic hinge and the second dynamic hinge respectively in "; " font, one end of first dynamic hinge and the second dynamic hinge is fastened and connected by voussoir is concavo-convex, the limit, round dot side of the other end is provided with rotating shaft, and connected by rotating shaft, the first dynamic hinge and second moves the plane of round dot transverse plane higher than this end of hinge.Meanwhile, the first dynamic hinge and the second dynamic hinge are connected as a single entity by chapiter screw 1, and the two ends of rotating shaft are respectively equipped with protruding square head, and square head inserts four square holes of junction described in the first hinge and the second hinge respectively.Rotating shaft is arranged at simultaneously to be determined in two relative through-hole passage of hinge, is respectively equipped with sealing ring 2 in the first dynamic hinge at rotating shaft two ends and the second dynamic hinge, and determine to be " T " three through holes in hinge, the middle side of rotating shaft is provided with two adjacent flat key grooves; Be provided with guide, Rectangular Spring, sealing screw in another through-hole passage of hinge successively, guide is offseted by a wherein flat key groove of Rectangular Spring and rotating shaft.
During use, be installed on doorframe by determining hinge, dynamic hinge is installed on door-plate, and this inner hinge can be installed on the side inside door-plate; When rotating door-plate, guide drives Rectangular Spring generation deformation, and door-plate is subject to resistance and need enforces.When door-plate rotate in place, guide slides into another flat key groove by a flat key groove of rotating shaft, and guide overcomes the damping force of the fin arm of angle between flat key groove, and door-plate position is fixed again, and Rectangular Spring resets, and this flat key groove of guide and rotating shaft offsets again.
Design feature of the present utility model: the flat key groove in the middle part of rotating shaft is the plane of speciality, controls by two Plane Angle controlling rotating shaft adjacent the orientation angle being provided with this inner hinge door-plate; The degree of depth be screwed into by controlling sealing screw carrys out the pressure of control rectangle spring, thus controls the detent force of this inner hinge; Because the elastic force of Rectangular Spring is comparatively large, therefore seal screw and adopt interior hexagonal pointless screw, instrument easy to use regulates; Add lubricating grease between rotating shaft and guide, the friction with guide in axis of rotation process can be reduced; Be provided with sealing ring between rotating shaft and dynamic hinge, the inside preventing dust from entering this inner hinge also prevents inner lubricating grease from flowing out simultaneously further.This inner hinge applies pressure by Rectangular Spring makes the flat key groove plane of guide and rotating shaft be close to generation detent force, door-plate is made to be positioned at certain angle, also can not oneself switch in violent vibration Xiamen, on door-plate, only apply enough large power door-plate just can be made to rotate.
