Description

Assembly Structure of Wings for Door Handle

The present invention relates to a wing pivot structure for a door handle, and more particularly, to open and close a door attached to a cylindrical box having an opening door, such as a telephone terminal box, a fuse box or a girder insulation box, or more broadly a safe and a cabinet. The door handle is designed to improve the durability and operability of the door handle while being rotated without interfering with the door frame when intermittent.

In general, a telephone box, a fuse box, or a variety of gauge insulation box is a rectangular enclosure, and the front door is open to the outside to open and close the door as needed, from time to time open the door for each purpose The door handle, which is a locking device, is installed as a countermeasure against the necessity accompanied by a meter reading, repair or verification, and the inadvertent operation of children and various safety accidents.

The locking door handle is fixed to the door (D), the lever 21 is moved by the pressing of the button facing the front, so as to be caught in the door frame by the interruption of the cam curve 31 formed on the wing (30). The door 30 is opened by rotating the wing 30 positioned to release the latch, and when the door is closed again, the lever 21 is moved in a rising direction and the wing 30 is caught by the door frame. It is moved to maintain the closed state.

Therefore, in recent years, many configurations have been proposed for improving contactability and operability between the wing of the door handle which intercepts the door and the door frame.

The wing pivoting structure for a conventional door handle configured as described above is simply configured to be in contact with the intermittent surface of the door frame while the wing is rotated around the shaft and the guide projection in the lateral direction by the pressing of the button. Since locking is performed, wear and damage of the wings are generated when used for a long time, there is a problem such as a malfunction.

That is, since the locking part of the wing and the intermittent surface of the door frame are locked by the surface contact when the door is locked, the door is not opened smoothly due to long time use or wear, and the durability of the door handle is also reduced. There was a discontinuance.

In addition, there was a problem that the rotational operability of the wing can not be made smoothly due to its own direct contact with the body rear portion during the rotation of the wing.

The object of the present invention is to form a guide surface having a predetermined inclination to both sides of the center of the rear surface of the body of the door handle, which prevents contact with the rear surface of the body and the intermittent surface of the door frame at the time of rotation of the wing by pressing the button. Since locking and releasing is performed in a state, durability and operability of the entire door handle including the wing can be improved.

Another object of the present invention is to provide a wing pivot structure for the door handle to improve the reliability of the product.
