Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figures 1 to 7, the door hinge structure in the present embodiment comprises the primary clusterings such as hinge seat 1, hinge fork 2, hinge connecting rod 3, extension spring 4, stage clip mechanism 5.
With direction shown in Fig. 1 arrow A for forward direction, the bottom of hinge fork 2 is hinged with the front end of hinge seat 1 by the first jointed shaft 71, the top of hinge seat 1 is located at by hinge connecting rod 3, the front end of hinge connecting rod 3 is hinged with the bottom of hinge fork 2 by the second jointed shaft 72, the rear end of hinge connecting rod 3 is provided with the first installation shaft 81, the rear end of hinge seat 1 is provided with the second installation shaft 82, the front end of extension spring 4 is arranged in the first installation shaft 81, the rear end of extension spring 4 is arranged in the second installation shaft 82, and extension spring 4 is in extended state all the time.
Stage clip mechanism 5 to be arranged on hinge seat 1 and to be positioned at the below of hinge connecting rod 3.Particularly, the two side of hinge seat 1 front end all has and is horizontally disposed with and the bar shaped installing hole 11 distributed from front to back, in the inside of hinge seat 1 and the rear being positioned at bar shaped installing hole 11 is provided with vertical spacing plate 12, vertical spacing plate 12 has spacing hole 13.Stage clip mechanism 5 in the present embodiment comprises sliding axle 51, stage clip bar 52 and stage clip 53, sliding axle 51 is horizontally disposed with and perpendicular to the length direction of bar shaped installing hole 11, the two ends of sliding axle 51 are located in the bar shaped installing hole 11 of respective side respectively, sliding axle 51 under the effect of external force can in bar shaped installing hole 11 before and after to slip, stage clip bar 52 is horizontally disposed with and perpendicular with sliding axle 51, the front end of stage clip bar 52 is fixed on the centre of sliding axle 51, the rear end of stage clip bar 52 is located in spacing hole 13, stage clip 53 is set on stage clip bar 52, stage clip 53 is in compressive state all the time, the front end of stage clip 53 and the leading section of stage clip bar 52 offset, rear end and the described limiting plate 12 of stage clip 53 offset.
Be formed with arc notch 21 in the bottom of hinge fork 2, preferentially adopt arc gap, sliding axle 51 is arranged with pulley 54, pulley 54 can directly act on hinge fork 2 as force application part.Under being at door the state closed and open and be less than set angle, pulley 54 to embed in arc notch 21 and offsets with the arcwall face of arc notch 21, and under opening at door the state exceeding set angle, pulley 54 departs from arc notch 21, in the present embodiment, above-mentioned set angle is set as 20 ~ 25 °.Because stage clip 53 is in compressive state all the time, thus when pulley 54 embeds in arc notch 21, the power that stage clip 53 produces promotes the bottom of hinge fork 2 by sliding axle 51 and pulley 54, thus forms the power stoping door to be opened.After pulley 54 departs from arc notch 21, the force to hinge fork 2 removed by stage clip 53, and namely stage clip 53 no longer produces the power stoping door to be opened.
Be provided with the first chute 31 in the front bottom end of hinge connecting rod 3, under the door state of pass, while in the arc notch 21 of pulley 54 front side portion insert hinge fork 2, pulley 54 top is embedded in the first chute 31 simultaneously, thus it is spacing further that pulley 54 is able to.Bottom in the middle of hinge connecting rod 3 is provided with the second chute 32, be fixed with limit shaft 6 at the correspondence position of hinge seat 1, limit shaft 6 is arranged with position-limited wheel 61, under the door state of pass, position-limited wheel 61 embeds in the second chute 32, thus carries out spacing further to hinge connecting rod 3.In door opening process, limit shaft 6 and position-limited wheel 61 progressively depart from from the second chute 32.
In the present embodiment, the first jointed shaft 71, second jointed shaft 72, first installation shaft 81, second installation shaft 82, sliding axle 51 and limit shaft 6 all adopt rivet to make, and structure is simple, firmly and install very convenient.
In addition, as shown in Figure 5 and Figure 6, the front end of hinge seat 1 has front plan 14, the bottom of hinge fork 2 has bottom plane 22, hinge fork 2 turns to bottom plane 22 and collides with front plan 14 and form the maximum open angle of a body, and the maximum open angle of this body is less than 180 °, bottom plane 22 and front plan 14 can prevent the open angle from increasing further after colliding.
As shown in Figure 8, door body 9 two bottom sides is separately installed with a door hinge, door hinge has two and is arranged on the two bottom sides of a body 9 respectively, and door body 9 is fixed with hinge fixing plate (not shown), and the hinge fork of door hinge is fixed on hinge fixing plate.
The course of work of this door hinge is as follows:
During enabling, start to rotate counterclockwise with the hinge fork 2 that door body 9 is fixing, hinge fork 2 drives hinge connecting rod 3 to move forward, hinge connecting rod 3 pulls open forward extension spring 4, the arc notch 21 of hinge fork 2 is relative with pulley 54 simultaneously rolls, stage clip bar 52 is promoted backward, the stage clip 53 be now set on stage clip bar 52 starts to compress and produces bounce, the angle opened along with hinge fork 2 increases, extension spring 4, the power that the prevention door that stage clip 53 produces is opened becomes large gradually, but when door is opened to 20 ~ 25 °, the arc notch 21 of hinge fork 2 slips over pulley 54, stage clip 53 resilience and no longer working, extension spring 4 is now only had to work, thus prevent the power of enabling increasing, and then make the feel of whole door opening process keep moderate.Door is when opening to maximum angle, and hinge fork 2 turns to bottom plane 22 and collides with front plan 14, ensures that the maximum open angle of door is less than 180 degree, thus avoids the dish landing that is placed on door.
At closing time, hinge fork 2 starts to rotate clockwise, and extension spring 4 is in the state of pulling open, and extension spring 4 pulls hinge connecting rod 3 to move backward, and hinge connecting rod 3 pulls hinge fork 2 to rotate clockwise, and decreases required manpower of closing the door, the feel maintained.Hinge fork 2 continues to rotate clockwise, and when turning to door and being opened to 20 ~ 25 °, because the arc notch 21 of hinge fork 2 starts to contact with pulley 54, promote stage clip bar 52 and move right, stage clip 53 is further compressed.When door closed put in place time, stage clip 53 still keeps compressive state, promoting hinge fork 2 makes hinge fork 2 have the trend continuing to rotate clockwise, but put in place because door has closed, therefore, the screen resilience of stage clip 53 makes to continue to compress header board and applies certain to fasten power with opposite house, thus prevents steam, microwave leakage.
