Specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with the utility model reality
The attached drawing in example is applied, the technical solutions in the embodiments of the present invention are clearly and completely described.
Schematic diagram is opened for the structure chart and traditional door hinge of traditional door hinge, currently on the market the conventional door of electric cabinet
Plate opening angle generally can only achieve 120 ° and following door-plate, due to the limited angle system of unlatching, be unfavorable for the peace of electric cabinet
Dress and maintenance.
As shown in figs 1-9, a kind of novel door hinge, including dynamic hinge 1, quiet hinge 2 and connecting shaft 4, move hinge 1 and quiet hinge
Chain 2 is rotatablely connected by connecting shaft 4, is provided with the position limiting structure that can limit 1 rotational angle of Brake hinge on dynamic hinge 1, is moved hinge
When chain 1 rotates more than 150 °, position limiting structure offsets with quiet hinge, 14 cambered surfaces of contact surface.Position limiting structure is limited Brake hinge 1
With the structure of quiet 2 rotational angle of hinge, when dynamic hinge 1 turns to certain angle relative to quiet hinge 2, position limiting structure and quiet hinge
Chain 2 offsets, it is prevented that dynamic hinge 1 continues to rotate, for the ease of the installation and maintenance of electric cabinet, door-plate 6 and cabinet body 7
Best open angle is 180 °.More preferably cooperate the relative rotation of dynamic hinge 1 and quiet hinge 2, limit knot for the ease of position limiting structure
Structure includes the contact surface 14 being arranged in 4 rotation direction of connecting shaft, is referred in 4 rotation direction of connecting shaft with dynamic hinge 1 and quiet hinge
2 original state of chain is starting point, dynamic hinge 1 with connecting shaft 4 is the center of circle and the motion profile rotated, the arc of contact surface 14 can be with
The motion profile is rotated to cooperation.
Dynamic hinge 1 includes turntable 15, rotor plate 16 and connecting plate 17；Being provided on turntable 15 can be for connecting shaft 4
It is pierced by through-hole 12, rotor plate 16 and connecting plate 17 are installed on turntable 15 and are mutually perpendicular to, one end of contact surface 14 and company
Fishplate bar 17 connects, and the other end extends to 15 outside of turntable.When dynamic hinge 1 and quiet hinge 2 are original state, contact surface 14 and company
The side that fishplate bar 17 connects is closer to quiet hinge 2, when dynamic hinge 1 starts turning, until contact surface 14 extends to outside turntable 15
The side of side offsets with hinge 2, and the rotation for moving hinge 1 and quiet hinge 2 terminates, at this point, for dynamic 2 stop bit of hinge 1 and quiet hinge
It sets, i.e., dynamic hinge 1 and the maximum rotational angle of quiet hinge 2, therefore, contact surface 14 extend to the position of the side in 15 outside of turntable
Relationship affect is set to 2 rotational angle of dynamic hinge 1 and quiet hinge.Specifically, when contact surface 14 extends to 15 outside of turntable
When side is closer to 4 position of connecting shaft, the rotational angle for moving hinge 1 and quiet hinge 2 is small；When contact surface 14 extends to turntable
When the side in 15 outsides is further from 4 position of connecting shaft, the rotational angle for moving hinge 1 and quiet hinge 2 is big.
Hinge further includes the pressing plate 5 with mounting hole 51, and boss 11,11 energy of boss and mounting hole are provided on connecting plate 17
51 cooperations, for fixing door-plate 6, such hinge can drive door-plate 6 to rotate together.In order to enable rotating more flexible, hinge
On further include that can be provided with connecting column 31 on gasket 3 for the gasket 3 that connecting shaft 4 is pierced by, along through-hole 12 on turntable 15
The center of circle be symmetrically arranged with connecting hole 13, connecting column 31 be capable of fixing in connecting hole 13.When the rotation of dynamic hinge 1, due to gasket 3
It is fixed on turntable 15, therefore, gasket 3 will also be rotated with the rotation of dynamic hinge 1, and gasket can also play buffering
Effect, especially when door-plate 6 is installed on dynamic hinge 1, dynamic hinge 1 can undertake more gravity in the rotation, and pacify
2 processing accuracy of dynamic hinge 1 and quiet hinge can not only be reduced by having filled gasket 3, can also make the rotation of dynamic hinge 1 more clever
It is living.In addition, for the ease of installing connecting shaft 4, so that connecting shaft 4 is easier to be inserted into dynamic hinge 1, quiet hinge 2 or gasket 3,
The end of connecting shaft 4 is provided with chamfering 41.
Quiet hinge 2 includes the first mounting plate 24 and the second mounting plate 25, and the side of the first mounting plate 24 is provided with for even
The crimping 21 that spindle 4 is pierced by, the other side is vertical with the second mounting plate 25 to be connect and the first mounting plate 24 and the second mounting plate 25
Junction is provided with reinforcing rib 22, and U-type groove is provided on quiet hinge 2, and rotor plate 16 can cooperate with the U-type groove.Second mounting plate
25 are fixedly connected with cabinet body 7, and connecting shaft 4 can be once inserted into the crimping 21 of quiet hinge 2 and the through-hole 12 of dynamic hinge 1, dynamic in this way
Hinge 1 and quiet hinge 2 are just able to rotate and are connected to, and when U-type groove is overlapped with rotor plate 16, moves hinge 1 and quiet hinge 2 is in initial
Position, that is, the state that door-plate 6 is closed move hinge 1 and quiet hinge 2 are in 180 ° when U-type groove is parallel with rotor plate 16
Final position, that is, the state that door-plate 6 is opened.
Obviously, described embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in every other embodiment.
