Detailed Description

Referring to FIGS. 1 to 12, a mechanical door handle comprises a handle base 1, a reversible door handle 3 is mounted on the handle base 1 through a first rotating shaft 2, a control mounting seat 4 is mounted beside the handle base 1, one end of the first rotating shaft 2 extends into the control mounting seat 4 and is fixedly connected with one end of a movable plate 5, a pressing block 6 is arranged at the other end of the movable plate 5, a fixed shaft 7 is mounted on the control mounting seat 4, a swinging seat 8 capable of sliding along the axial direction and rotating is sleeved on the fixed shaft 7, the swinging seat 8 comprises a turnover block 8-1 at one end and a connecting block 8-2 at the other end connected with one end of a first torsion spring 9, the first torsion spring 9 is sleeved on the fixed shaft 7, the turnover block 8-1 is connected with the connecting block 8-2 through a connecting rod 8-3, an inclined block 10 is arranged between the overturning block 8-1 and the connecting block 8-2 and near one end of the overturning block 8-1, the inclined block 10 is sleeved on the fixed shaft 7 and can axially slide, an intermediate seat 11 is arranged between the inclined block 10 and the connecting block 8-2, the other end of the first torsion spring 9 is connected with the intermediate seat 11, a limit groove which is used for preventing the inclined block 10 from rotating is arranged on the intermediate seat 11, so that the inclined block 10 can only axially move but not rotate, a pressure receiving part 8-4 and a pushing part 8-5 are arranged on the overturning block 8-1, the pressure receiving part 8-4 is matched with the pressing block 6, a pressing and spring mechanism 12 is arranged on the control mounting seat 4, a pushing block 13 is arranged on a movable rod of the pressing and spring mechanism 12, a pushing part 13-1 which is arranged on one side of the fixed shaft 7 and is matched with the side surface of the movable plate 5, a bevel 13-2 which is matched with the inclined block 10 is arranged on the pushing block 13, the pushing block 13 is also provided with a reset part 13-3 which is positioned at the other side of the fixed shaft 7 and matched with the pushing part 8-5. The ejection mechanism 12 used in this embodiment is configured to reciprocate by pushing the ball pen and the fountain pen to eject the ball pen and pushing the ball pen again to retract the ball pen. A second torsion spring 14 is installed on the first rotation shaft 2 to facilitate the reset of the door handle 3.

In order to better realize the mechanical transmission effect, convex points 15 are respectively arranged on the contact surfaces of the movable plate 5 and the pushing part 13-1; a bump 15 is also provided on the contact surface between the pressing portion 8-5 and the reset portion 13-3.

The door opening process of the invention is as follows: in the initial state, the movable rod of the spring pressing mechanism 12 is in a retracted state, the push block 13 is not contacted with the movable plate 5 and the inclined block 10 or just contacted with the movable plate 5 but does not apply force, the movable plate 5 is not contacted with the swinging seat 8, the first torsion spring is in a natural state and enters a door opening action, the rear end of the door handle 3, namely the end A in the drawing, the rear end of the door handle 3 turns inwards by about 8 degrees, namely the door handle 3 opens to 8 degrees, the first rotating shaft 2 rotates to drive the movable plate 5 to positively swing towards one side of the push block 13 and press the push part 13-1 on the push block 13, the movable rod of the spring pressing mechanism 12 is retracted for a small distance to the bottom, then the hand pressing the door handle 3 is released, the movable rod of the spring pressing mechanism 12 outwards pops to drive the push block to move towards one side of the fixed shaft, the push part 13-1 reversely swings the movable plate to enable the door handle 3 to be outwards opened by about 23 degrees, and simultaneously, the inclined surface 13-2 on the pushing block 13 moves to contact with the inclined block 10 and pushes against the inclined block 10 to move towards the movable plate 5 along the axial direction, the inclined block 10 also pushes the swinging seat 8 to move together, the pressing block 6 on the movable plate 5 contacts with the pressed part 8-4 of the turnover block 8-1, the first torsion spring 9 is in a contracted state, and finally the door opening action is performed, the door handle 3 continues to open outwards by about 40 degrees, the pressing block 6 on the movable plate 5 pushes the swinging seat 8 to swing reversely, the pushing part on the swinging seat 8 contacts with the reset part 13-3 and pushes the pushing block 13 back to enable the movable rod to retract to a retracted state, the door handle is released after the door is opened, the door handle 3 and the movable plate 5 are reset under the action of the second torsion spring 14, the swinging seat 8 is reset under the action of the first torsion spring 9 because the pressing block 6 on the movable plate 5 no longer presses the swinging seat 8, while being reset together with the ramp 10.

Besides the above door opening operation, the following door opening mode may be used, in which the front end of the door handle 3 is directly pressed by the thumb to open the rear end of the door handle 3 by about 23 ° outwards, then the door opening operation is performed to open about 40 °, at this time, the movable plate 5 swings reversely, and since the swing seat 8 is not contacted with the movable plate 5 at this time, the swing seat 8, the push block 13 and the spring pressing mechanism 12 are not affected, and the movable plate 5 is reset under the drive of the first rotating shaft 2 after the door is opened.
