Abstract
A kind of locking door-hinge, including：Fixed plate, rotating shaft base, torsionspring, extension spring, N number of rigid boss, N number of elastic plectrum and rotating shaft base drive device.When opening door body, by applying thrust to door body, after being stopped by rigid boss elastic deformation occurs for each elastic plectrum, and when door body, which is opened, no longer applies thrust to certain angle, because rigid boss stops elastic plectrum, door body realizes locking.When door body turns to certain aperture, rotating shaft base drive device driving rotating shaft base move up, extension spring is stretched, and rigid plectrum departs from from rigid boss, now in the presence of torsionspring rotating shaft base to back rotation, therefore realize door body close.Locking after being stopped due to door body in opening process with any angle, facilitates daily life.
Description
Technical field
It the utility model is related to door-hinge field, and in particular to a kind of locking door-hinge.
Background technology
It is well known that traditional door-hinge simply plays rotary spacing effect, door body is set to be rotated around door-hinge, Wu Fashi
The now function of locking in place, therefore when doorframe and ground out of plumb or when having wind to blow door body, door body can be automatically turned on or closed
Close, influence normal use.
Utility model content
The utility model is in order to overcome the shortcomings of above technology, there is provided one kind can make door body optional position when opening
The locking door-hinge that stops and can be closed automatically after maximum opening angle is turned to.
Technical scheme is used by the utility model overcomes its technical problem：

Flabellum I, rotating shaft base side is plugged in by guide rail vertical sliding, some mounting holes are provided with the flabellum I
Ⅰ；
Torsionspring, it is set on main shaft, it is located in annular groove, and the length of the annular groove is more than the length of torsionspring
Degree, the jig arm I of torsionspring are fixed on rotating shaft base, and the jig arm II of torsionspring is fixed on main shaft；
Extension spring, in rotating shaft base, its upper end is connected with rotating shaft base inwall, its lower end and main shaft upper end phase
Connection；
N number of rigid boss, its mutual uniform intervals and is circumferentially arranged at fixed plate upper end；
N number of elastic plectrum, its mutual uniform intervals and is circumferentially arranged at rotating shaft base lower end；And
Rotating shaft base drive device, its drive rotating shaft base move up and down vertically, when extension spring in the raw when,
The lower end of each elastic plectrum is located between the adjacent rigid boss of each two.
Above-mentioned rotating shaft base drive device include eccentric setting in main shaft top and be vertically arranged push rod, be arranged at rotation
Axle bed upper end is in the guide surface I of semi-circular shape, the guide surface II for the semi-circular shape being arranged at below guide surface I and connects

Embodiment
Below in conjunction with the accompanying drawings 1, accompanying drawing 2 is described further to the utility model.
As shown in Figure 1, a kind of locking door-hinge, including：Fixed plate 2, its end are vertically arranged with main shaft 7, set on main shaft 7
It is equipped with annular groove 10；Flabellum II 4, the side of fixed plate 2 is fixed on vertically, some mounting holes II 6 are provided with flabellum II 4；
Rotating shaft base 3, in tube-shaped structure, vertical turning set is loaded on main shaft 7；Flabellum I 1, it is plugged in by the vertical sliding of guide rail 20
The side of rotating shaft base 3, some mounting holes I 5 are provided with flabellum I 1；Torsionspring 11, it is set on main shaft 7, it is located at ring
In shape groove 10, the length of annular groove 10 is more than the length of torsionspring 11, and the jig arm I 12 of torsionspring 11 is fixed on rotary shaft
On seat 3, the jig arm II 13 of torsionspring 11 is fixed on main shaft 7；Extension spring 16, in rotating shaft base 3, its upper end with
The inwall of rotating shaft base 3 is connected, and its lower end is connected with the upper end of main shaft 7；N number of rigid boss 8, its mutual uniform intervals and along circle
Circumferential direction is arranged at the upper end of fixed plate 2；N number of elastic plectrum 9, its mutual uniform intervals and is circumferentially arranged at rotary shaft
3 lower ends of seat；And rotating shaft base drive device, it drives rotating shaft base 3 to move up and down vertically, when extension spring 16 is in nature
During state, the lower end of each elastic plectrum 9 is located between the adjacent rigid boss 8 of each two.Peace is passed through by threaded fastener
Flabellum II 4 is fixed on doorframe by dress hole II 6, and flabellum I 1 is fixed on into door body through mounting hole I 5 by threaded fastener
On, when opening door body, by applying thrust to door body, each elastic plectrum 9 occurs elasticity after being stopped by rigid boss 8 and become
Shape, successively across each rigid boss 8 after each flexural deformation of elastic plectrum 9, simultaneously because rotating shaft base 3 is relatively fixed axle bed
2 rotate, and now torsionspring 11 twists, when door body, which is opened, no longer applies thrust to certain angle, due to rigid boss 8
Elastic plectrum 9 is stopped, therefore door body can not be to back rotation, simultaneously because the elastic force of torsionspring 11, door body can not be certainly
By rotating forward, door body realizes locking.When door body turns to certain aperture, rotating shaft base drive device driving rotating shaft base 3
Move up, extension spring 16 is stretched, and rigid plectrum 9 departs from from rigid boss 8, is now rotated in the presence of torsionspring 11
Axle bed 3 realizes that door body is closed to back rotation.After door body is closed, rotating shaft base drive device driving axle bed 3 moves down, and makes every
The lower end of individual elastic plectrum 9 is again positioned between the adjacent rigid boss 8 of each two, is realized and is resetted.Because door body was being opened
Locking after Cheng Zhongke is stopped with any angle, facilitates daily life.
As shown in Figure 2, rotating shaft base drive device includes eccentric setting in the top of main shaft 7 and the push rod that is vertically arranged
14th, the guide surface I 17 that the upper end of rotating shaft base 3 is in semi-circular shape, the semicircular ring being arranged at below guide surface I 17 are arranged at
The guide surface II 19 of shape and the guiding surface 18 for being connected to guide surface I 17 and guide flat II 19, guide surface I
17th, guiding surface 18 and guide surface II 19 form the cirque structure of closing in overlook direction.During original state, stretching
Spring 16 pulls the head end of the push rod 14 of the upper end of main shaft 7 to be contacted with guide surface I 17, now the lower end position of each elastic plectrum 9
Between the adjacent rigid boss 8 of each two, elastic plectrum 9 plays barrier effect.When the head end and guide surface I of push rod 14
The rotational angle when whole process of 17 contacts is opened for door, when door stops at an arbitrary position, rigid boss 8 stops elastic dialing
Piece 9, door can be motionless with locking.When door, which is opened to maximum angle and continuation, to be promoted forward, the head end of push rod 14 is along guiding surface
18 slide into guide surface II 19, because the position of guide surface II 19 is less than guide surface I 17, therefore the quilt of rotating shaft base 3
Push rod 14 is promoted and moved up, and now extension spring 16 stretches and elastic plectrum 9 departs from from rigid boss 8.Torsionspring 11 drives
Rotating shaft base 3 rotates, and the head end of push rod 14 moves along guide surface II 19, door body close, until its along guiding surface 18 again
Slide at guide surface I 17, now extension spring 16 drives rotating shaft base 3 to move down, and makes the lower end of each elastic plectrum 9 again
Between the secondary rigid boss 8 adjacent positioned at each two, realize and reset.
Further, the top of push rod 14 is provided with bulb 15.Pass through bulb 15 and guide surface I 17, guiding surface 18
And the CONTACT WITH FRICTION of guide surface II 19 can reduce frictional force, the smooth degree that door-hinge rotates further is improved.
