Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A mounting structure of door handle, refer to fig. 1 and 3, including door 1, two mounting panels 2 of fixing on the square bar lateral wall and rotate the handle 4 of connection on mounting panel 2 through pivot 3, handle 4 is the L type, and door 1 surface is offered and is used for placing mounting groove 5 of handle 4.

Referring to fig. 2 and 3, a worm wheel 6 is fixed on the rotating shaft 3, a worm 7 rotatably connected with the worm wheel 6 is rotatably mounted on the side surface of the square rod, a driving block 8 is fixed on the worm 7 and positioned between the two mounting plates 2, and a spring 9 is connected between the driving block 8 and the mounting plates 2. When the door 1 is opened and closed, the handle 4 is rotated by hand, so that the worm wheel 6 drives the worm 7 to rotate, and the driving block 8 stretches the spring 9; after finishing opening and closing door 1, the handle is released to the hand, and spring 9 pulling drive block 8 for worm 7 drives turbine 6 and rotates, makes the handle automatic return to in mounting groove 5, prevents that people from colliding with handle 4 when the process and causing the condition of injury to take place.

Further, in order to limit the rotation range of the handle 4, a baffle 10 is installed on the side wall of the mounting plate 2, and when the handle 4 rotates 90 degrees and is positioned outside the mounting groove 5, the handle 4 abuts against the baffle 10.

It is worth mentioning that a cushion pad 11 is installed at a side where the baffle 10 abuts against the driving block 8 in order to reduce an impact force generated when the baffle 10 abuts against the driving block 8.
