The handle is formed with a positioning hole communicating with the combination hole. The lock set includes an inner disk unit and an outer disk unit each provided with a shaft tube, for combination with ornamental covers each having a combination portion, so that the combination hole of the handle may be mounted on the combination portion from the first surface or the second surface, and the handle may be fixed by a positioning member.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a direction changeable handle lock structure, and more particularly to a direction changeable handle lock structure, wherein the handle of the handle lock may be selectively pressed in the clockwise or counterclockwise direction according to the user's requirements.
2. Description of the Related Art
As shown in
FIG. 1
, a handle lock
91
used for a door plate
90
is usually mounted on the left side or right side of the door plate
90
according to the user's requirement. The handle lock
91
includes a handle
92
that may be pressed in the clockwise or counterclockwise direction, to drive the lock tongue
94
of the lock latch
93
to retract inward.
As shown in
FIG. 2
, a conventional handle lock structure is disclosed in U.S. Pat. No. 5,286,074 is shown. In such a conventional handle lock structure, the handles
81
are arranged in a symmetric manner. The normal face or opposite face of the handle
81
may be mounted on the shaft tube
83
by the combination portion
84
of the shaft tube
83
being inserted into the combination hole
82
of the handle
81
. The shaft tube
83
is provided with a circular hole
85
of insertion of the cap
86
which has an annular groove
87
aligning with the screw bore
88
of the shaft tube
83
, so that the screw
89
may be screwed into the screw bore
88
of the shaft tube
83
and inserted into the annular groove
87
of the cap
86
for fixing the cap
86
. However, such a conventional handle lock structure is not provided with a locking function, so that it can only used in a passageway door plate without needing locking, and cannot be available for the site needing locking.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a direction changeable handle lock structure, wherein the handle of the handle lock may be mounted at the left side or right side of the door plate according to the user's requirements, and may be selectively pressed in the clockwise or counterclockwise direction according to the user's requirements.
A secondary objective of the present invention is to provide a direction changeable handle lock structure, wherein the handle of the handle lock may be combined with a lock set needing the locking or unlocking function according to the user's requirements.
In accordance with the present invention, there is provided a direction changeable handle lock structure including two handles each provided with a first surface and a second surface, and each formed with a combination hole extended through the first surface and the second surface. The handle is formed with a positioning hole communicating with the combination hole. The lock set includes an inner disk unit and an outer disk unit each provided with a shaft tube, for combination with ornamental covers each having a combination portion, so that the combination hole of the handle may be mounted on the combination portion from the first surface or the second surface, and the handle may be fixed by a positioning member.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
