Slot 230, door body mounting rod 100 are equipped with the longitudinal chute 140 oriented along its length, and slide-bar 820 is slidably fit into
In horizontal concrete chute 230 and longitudinal chute 140.Horizontal concrete chute 230 and longitudinal chute 140 be can use in this way to door body mounting rod
100 rotation is limited, and is not only convenient for improving the rotation precision of door body mounting rod 100, and compared to setting arc limit slot
Mode, convenient for simplify horizontal concrete chute 230 and longitudinal chute 140 processing technology, further convenient for improve door body hinge 1 plus
Work efficiency rate.
More specifically, door body mounting rod 100 is pivotably mounted on hinge seat 200 by shaft 810, shaft 810
It is arranged with limit shaft sleeve 830 outside with slide-bar 820, limit shaft sleeve 830 plays position-limiting action to door body mounting rod 100.
Specifically, as shown in fig. 6, when the rotational angle of 100 opposite from hinge seat 200 of door body mounting rod is 12 degree, idler wheel
711 is inconsistent with the highest point of backstop boss 210, and roller shaft 713 slides up along the gyro wheeling concrete chuting 111 of door body mounting rod 100
To the top of gyro wheeling concrete chuting 111, roller shaft 713 drives the second elastic component 720 of compression upwards of rolling wheel support 712, thus in idler wheel
711 with biggish conflict power is generated at the contact point on 210 surface of backstop boss.When 100 opposite from hinge seat 200 of door body mounting rod
When rotational angle is less than 12 degree, the conflict power generates shutdown torque to door body mounting rod 100, to keep the door body real
The movement of existing automatic door-closing and play the role of good locking again after door body closing, ensure that the door body has very well
Leakproofness.
According to Hooke's law, spring is after deformation occurs, it will generates a deformation power F1=KX, wherein K is the rigid of tension spring
Angle value, X are the deformation quantity of tension spring.F1 is ultimately applied to the hinge of driving member 610 Yu hinge seat 200 by the transmitting of leash 600
On contact, if spring force F1 is L to the arm of force of shaft 810, then power F1 will generate a counter balance torque M1=to shaft 810
F1×L.Assuming that the door body Mass Distribution is uniform, door body center of gravity is located at the geometric center of the door body, therefore door body weight is to turning
The torque of axis 810 is M=0.5mgHsin θ, and wherein H is the height of the door body.It, can by selecting suitable spring rate K value
So that counter balance torque M1 is equal to the torque M of door body gravity, meet door body equilibrium condition M1=M, therefore play balance oven door
Effect.
After the rigidity of the first elastic component 400 of hinge 1 chooses type, in the door body opening procedure, the first elastic component
400 elastic force that can be provided be it is determining, the torque of elastic force can only balance the torque of the door body gravity of certain mass, the first elasticity
400 stiffness K value of part and door body mass M correspond.For the door body of different quality, in the first elastic component 400 and traction
Damping unit 500 is designed between band 600, one end of damping unit 500 is connected with the first elastic component 400, the other end and traction
Band 600 is connected.During hinge 1 is opened, leash 600 drives sliding part 300 to move along sliding part bracket 150,
So that the friction plate 510 being sheathed on the second hanging scroll 330 and pin shaft 340 is slided relative to sliding part bracket 150.
After hinge 1 assembles, pressure spring 520 has certain pre compressed magnitude, and friction plate 510 is acted in the pressure of pressure spring 520
Under, friction plate 510 is tightly contradicted with 150 contact surface of sliding part bracket, and a force of sliding friction F2 is generated in sliding process, should
Force of sliding friction F2 is ultimately applied on the hinge joint of driving member 610 and hinge seat 200 by the transmitting of leash 600, thus
One torque M2 is generated to shaft 810.In order to make the door body for being equipped with the hinge 1 that there is optimal counterbalance effect, hindering
Screw adjustments 530 are increased in Buddhist nun's device 500, screw adjustments 530 are holding screw, can play and adjust friction plate 510
With the effect of the contact forces of sliding part bracket 150, the size of the torque of frictional force is by 520 rigidity of pressure spring and screw adjustments
530 is common determining.Friction plate 510 uses nonmetallic wear-resisting, heat-resisting material.The counter balance torque M1's and torque M2 of frictional force
Under collective effect, hinge 1 can be made to be suitable for the door body of different quality, the versatility of hinge 1 is greatly improved, reduce hinge
The design cost of chain 1.
In switching process of the door body from the closed position to the open position, slide-bar 820 is along hinge seat 200
On horizontal concrete chute 230 slided outward from interior, while slide-bar 820 along door body mounting rod 100 longitudinal chute 140 from top to bottom
Sliding, slide-bar 820 plays the role of limit to hinge 1, so that the maximum rotation angle of hinge 1 does not exceed 90 degree.
Below with reference to the accompanying drawings the course of work of door body hinge 1 according to the utility model embodiment is described.
During door body overturning, 810 rotation around the shaft of door body mounting rod 100, driving member 610 is around connecting shaft
840 rotations, sleeve 131 contact with leash 600 and compress leash 600, so that leash 600 and 131 the tangent of sleeve produce
Raw bending deformation, leash 600 will drive limiting slot 151 of the sliding part 300 along sliding part bracket 150 in bending deformation process
Slide downward.One end of first elastic component 400 is hung on the first hanging scroll 170, and the other end is hung on the second hanging scroll 330, sliding part
It drives 400 slide downward of the first elastic component to generate elastic deformation by the second hanging scroll 330 when 300 sliding, makes the first elastic component
400 generate larger elastic force, so that sliding part 300 is generated larger frictional force when sliding by friction plate 510, to utilize the first elastic component
The torque that 400 elastic force and the frictional force of sliding part 300 generate jointly offsets the torque of the gravity of the door body, to realize door
The equalising torque of body hinge 1.
