Embodiment
The utility model is described in further detail with reference to specific embodiment.
Embodiment 1：
As shown in Figures 1 to 5, a kind of door hinge of the present utility model, including doorframe hinge 1, door leaf hinge 2 and bearing pin 3,
Doorframe hinge 1 includes the first axially hollow beam barrel 11 and first portion 12 being fixed on outside the first beam barrel 11, first portion 12
Provided with some doorframe fixing holes 121 for being used for fixing with doorframe edge, door leaf hinge 2 includes the second axially hollow beam barrel 21
With second portion 22 being fixed on outside the second beam barrel 21, second portion 22 is provided with some door leafs for being used for fixing with door leaf edge
Fixing hole 221, bearing pin 3 is also cross the first beam barrel 11 and the hollow space of the second beam barrel 21；The top of first beam barrel 11 has
Rotationally symmetrical top line edge 111, top line edge 111 is the structure that periodic undulations changes, and the bottom of the second beam barrel 21 has matching
Push up the shading edge 211 of the structure of line edge 111.Bearing pin 3 can keep the pivot joint state of doorframe hinge 1 and door leaf hinge 2.It is limited to push up line
In the structure of edge 111, door leaf switching process, the second beam barrel 21 actually can axially dipping and heaving, in this process, door
The heavy burden of fan hinge 2 can cause the oblique contact of top line edge 111 and shading edge 211 and produce hinder door leaf to close tangential point
Power, therefore, it is possible to play the effect for hindering door leaf quick closedown, instead of the effect of door closer.
As shown in figure 4, the anglec of rotation of top line edge 111 is 360 °/M, M is the integer not less than 5.The switch of door leaf typically exists
0 ~ 90 °, because top line edge 111 is rotationally symmetrical, meet the integral multiple of the anglec of rotation in opening angle, that door leaf is in gravity
It can just be stopped under effect, play a part of controlling door leaf aperture.When such as M is 5, it is 72 ° of positions that door leaf, which can be parked in aperture,；
When M is 20, door leaf can be parked in a certain position that aperture is 18 °, 36 °, 54 °, 72 °, 90 °.
As shown in figure 5, the zigzag structure that top line edge 111 changes in periodic undulations, each change week of top line edge 111
Include abrupt slope portion 1111 and gentle slope portion 1112 in phase.When door leaf is during unlatching, shading edge 211 is along gentle slope
Portion 1112 is up, and gravity can produce a less tangential component, so opens the door lighter；When door leaf is in the process of closing
In, shading edge 211 is up along abrupt slope portion 1111, and gravity can produce a larger tangential component, and so closing is more hard, together
When also door leaf closed by wind blows cause bigger resistance, improve anti-collision effect.
As shown in Figure 1 to Figure 3, the suitable for reading of the second beam barrel 21 is cased with decoction cap 4a.On upper decoction cap 4a energy hidden hinge
Hollow sectors, make outward appearance more preferably, be also avoided that finger is goed deep into the second beam barrel 21 and occurs to squeeze wound dangerous by children.
Embodiment 2：
As shown in fig. 6, being with the difference of embodiment 1：The anglec of rotation of top line edge 111 is that (N is just whole to 90 °/N
Number).So door leaf can rest on 90 ° of this open positions at least, and this is with regard to that can play a part of door-inhale.When N is more than 1, door
Fan can just be parked in other half-open positions.
As shown in fig. 7, being with the difference of embodiment 1：Push up the waveform knot that line edge 111 changes in periodic undulations
Structure.Compared to zigzag structure, the resistance that wavy shaped configuration is brought is smaller, but less susceptible abrasion.
Embodiment 3：
As shown in figure 8, being with the difference of embodiment 1：Bearing pin 3 and upper decoction cap 4a are replaced by a pin 5.Pin
The same effects of decoction cap 4a can be played by following closely 5 roomy heads, and the thinner body portion of pin 5 can be played as bearing pin 3
Effect, and dismounting pin 5 is both upper simpler than dismantling.
Embodiment 4：
As shown in figure 9, being with the difference of embodiment 1：The lower muzzle of first beam barrel 11 has lower decoction cap 4b.Upper dress
Decorations cap 4a and lower decoction cap 4b supports the use the rotating part that can prevent extraneous moisture from entering door hinge, prevents bearing pin 3 from getting rusty
Bring the problem of door leaf closes hard.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality
New protection domain.
