Specific embodiment
The present invention is further elaborated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, a kind of torque hinge of the present invention, including sliding seat 6, outside the one end of the sliding seat 6
Circle is provided with fixed seat 3, and friction sleeve 5 is provided between the sliding seat 6 and fixed seat 3, and the fixed seat 3 is enclosed within friction sleeve 5
On cylindrical, and the anti-rotation boss in fixed seat 3 is snapped in the anti-rotation groove of friction sleeve 5, so limits fixed seat 3 with friction
Cover 5 relative rotation and can only axially float, the sliding seat 6 is provided with terminal pad 2 near one end inner circle of friction sleeve 5, institute
State terminal pad 2 to be connected with sliding seat 6 and be inserted in the endoporus of friction sleeve 5 by key 4, so ensure that sliding seat 6 and connection
Disk 2 can only be moved axially, and the both sides end face of the friction sleeve 5 is in close contact respectively with sliding seat 6 and terminal pad 2, the activity
6 other end inner circles of seat are provided with torque spring 7, and through torque adjusting screw rod 8 is provided with the middle of the torque spring 7, the torque is adjusted
Section screw rod 8 is screwed in the screw of terminal pad 2, and the terminal pad 2 is provided with trip bolt 1, and the trip bolt 1 screws in power
In the screw of square adjusting screw rod 8, screw sleeve 9, the inner circle of the screw sleeve 9 are provided between the sliding seat 6 and torque spring 7
It is fitted close with torque spring 7.According to the length that the requirement of torque size, Torque-adjusting adjusting screw rod 8 are screwed in, i.e. controling power
The decrement of square spring 7 realizes the regulation of hinge rotating torque.After torque size is adjusted, trip bolt 1 is tightened, that is, locked
Torque adjusting screw rod 8, prevents from rotating, and makes torque size operationally will not change, as shown in Fig. 2 the torque
Removable insole pieces 10 are additionally provided between adjusting screw rod 8 and torque spring 7, as shown in figure 3, the close-fitting of spacer pin 11 is in sliding seat 6
Rotate on the end face that contact with fixed seat 3, contact accordingly in fixed seat 3 and stopper slot is provided with end face, spacer pin 11 can only be
Motion in stopper slot, therefore the folding of hinge can be controlled in certain angular range, as shown in figure 3,115 ° of folding angular range,
If desired for 360 ° of rotations of hinge, as long as then not installing spacer pin 11.Additionally, the mounting surface of the sliding seat 6 and fixed seat 3
On be all provided with 4 installation screws.
The operation principle of the present invention：A kind of torque hinge that the present invention is provided, under spring force, produces the fortune of frictional force
Moving part need to be brought into close contact, and after keeping them to have the trend of move toward one another, hinge to install, fixed seat 3 and sliding seat 6 are relative
Axial restraint, a friction sleeve 5 is designed between fixed seat 3 and sliding seat 6, for compensating axial rigging error and part
Axial wear extent, the decrement of Torque-adjusting spring 7, i.e. the regulation both sides end face of friction sleeve 5 and sliding seat 6 and terminal pad 2
Contact friction pressure, realizes the regulation to hinge rotating torque, can not only extend the service life of hinge, and is suitable for using
