Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6, the door handle of the present invention is installed for locking and unlocking the door 1 mainly for opening and closing, such as a cabinet or an electric switchboard.

The door 1 is connected to the frame 1 in such a manner that the door 1 can be opened to the frame body and the body 10 is fixed forward by piercing the mounting hole in the door 1, And a handle 20 rotatable together with the handle 20.

Inside the body 10, a locking device for locking the handle 20 is provided.

The bolt shafts 11 are normally formed in the shape of a square bar and have threaded portions formed at their respective corners. After inserting the lever 10 with the shaft hole, the bolt shaft 11 is fixed to the lever (not shown) by the nut 5 and the spring washers 6 12 are fixed in position.

In order to improve the strength of the lever 10, the bead curve having a gentle curvature in the longitudinal direction is formed while softening the engaging state and the contact during the releasing operation of the fixing frame or the securing door.

The locking device structure accommodates a key holder 30 which can be operated only by the key 2 at the lower end of the handle 20 and an eccentric projection 31 is formed by protruding at the end of the key holder 30.

When the eccentric projections 31 are inserted into the fitting holes 33 of the thin plate-shaped hooks 32, the hooks 32 are moved in the locked state and in the unlocked state in accordance with the operation of the keys 2 Up and down operation.

The pawl 32 is vertically lifted and lowered in the guide path of the housing 21, which is fastened and screwed on the inside of the lower end of the handle 20.

Therefore, since the keyhole 30 can not be rotated without the operation of the key 2, the locking member 32 is hooked on the locking groove 13, so that the lock 20 can not be drawn out from the body 10 (Fig. 2)

When the key holder 30 is rotated about 180 degrees by using the key 2, the eccentric protrusion 31 fitted in the fitting hole 33 of the catch 32 is simultaneously rotated The lock 32 is moved upward so as to escape from the locking groove 13, thereby releasing the lock. (Fig. 4)

On the other hand, the display device is installed to easily grasp the locked state and the unlocked state of the handle 20 from the outside with the naked eye.

That is, the window (22) is formed on the handle (20) with one side in a state where the keyhole (30) is accommodated.

The control protrusion 35 is protruded from the keyhole 30.

The control projection 35 is protruded and formed around the cylindrical key-holder 30 at a constant height while maintaining the shape of the semicylinder.

The operation ring 40 assembled for the indication of the locking state of the key holder 30 is ring-shaped with a certain thickness and the control projection 35 of the key holder 30 is fitted in the center thereof, The rotation hole 42 is penetrated.

At one side of the rotation hole (42), a locking protrusion (41) for catching the control protrusion (35) and moving the position is protruded at a certain height toward the center.

In addition, the lock ring 40 is protruded outside the operation ring 40 in a state of being represented by a color different from that of the key figure capable of recognizing the lock indication C and the release indication O.

The actuating ring 40 is inserted into the keyhole 30 so as to be in close contact with the position of the protrusion 45 protruding from the tip of the eccentric protrusion 31 of the keyhole 30.

At this time, the rotation hole 42 of the operation ring 40 is fitted to the outer diameter of the control projection 35, and the engagement protrusion 41 protruding inwardly is engaged with the outer periphery of the key holder 30 where the control projection 35 does not protrude It is located in the neck.

Fig. 5 shows the unlocking position of the key holder 30. Fig.

In this state, it is possible to observe that the unlocking indication O of the operating ring 40 is placed in the window 22 of the handle 20 and the lock is released from the outside.

When the key 2 is inserted into the key holder 30 and rotated clockwise when the key 2 is required to be locked, the left protruding surface of the control projection 35 contacts the engagement protrusion 41 of the actuating ring 40 The working ring 40 is still in place.

Then, when the keyhole 30 is rotated about 180 degrees, the left protruding face of the control protrusion 35 is rotated with the fixed angle operating ring 40 in a state in which the protruding face of the actuating ring 40 contacts the engaging protrusion 41 .

Thus, the lock indication C of the operating ring 40 is moved to the window 22 position of the handle 20 so that the user can see that the lock is in the locked state (Figure 6). [

When the key 2 is inserted in the key holder 30 in the opposite direction and the key ring 30 is rotated in the reverse direction, the operation ring 40 does not operate at a certain angle, The operating ring 40 can be reversely rotated to be switched to the unlocking position as shown in Fig.

Therefore, whether the handle 20 is in the locked state or in the unlocked state can be easily grasped visually, thereby improving the reliability of security maintenance.

The present invention having such a configuration can improve the inconvenience of the operator for confirming the lock and simplify the structure of the display device, thereby improving the merchantability and providing economical benefits.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

The present invention is applied to door handle technologies such as switchboards and cabinets. Particularly, the present invention is applied to a door handle field which allows easy visual confirmation of the locked state and the unlocked state of the handle.
