ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a remote-controlled lock, particularly to one in which a motor is controlled by a remote controller to rotate clockwise together with an actuating member to push a passive member to move forward and have its deadbolt extend outward and inserted in the engage groove of an engage base to finish locking of the remote-controlled lock, having excellent effect of anti-theft.
2. Description of the Prior Art
A conventional door lock, as shown in
FIG. 1
, includes a housing
10
provided inside with a lock base
11
. The lock base
11
is provided at one side with lock rods
110
able to extend out of the through hole
100
in the sidewall of the housing
10
and be inserted in an elongate groove
141
in the sidewall of a bolt base
140
on a doorjamb
14
. Besides, the lock base
11
has a lock core
111
with a keyhole
112
provided respectively at the inner and the outer side. A pull plate
12
is fitted in the inner side wall of the housing
10
, having a fixing plate
120
inserted in the slide groove
101
of the housing
10
and contacting the fixing plate
102
of the housing
10
. In addition, the housing
10
is provided inside with a deadbolt
13
having one end inserted through the fixing plate
102
of the housing
10
and secured with the fixing plate
120
of the pull plate
12
, with a spring
130
fitted around one end of the deadbolt
13
near the pull plate
12
. The deadbolt
13
has the other end fixed with a stopper
131
able to extend out of a through hole
103
in the sidewall of the housing
10
and be inserted in the elongate groove
141
in the sidewall of the bolt base
140
of the doorjamb
14
. Thus, a key is inserted in the keyhole
112
of the lock core
111
and turned around to drive the lock rods
110
and the stopper
131
to move inward toward the housing
10
and be disengaged from the elongate groove
141
of the bolt base
140
of the doorjamb
14
to finish unlocking of a door lock.
However, a conventional door lock has its lock rods
110
locked only by a key, therefore it is easy to be unlocked by common unlocking tools, having hardly effect of anti-theft.
SUMMARY OF THE INVENTION
The objective of the invention is to offer a remote-controlled lock having excellent effect of anti-theft.
The feature of the invention is a shell to be fixed on a door, formed inside with a chamber having two opposite projecting bars on the inner wall and two position plates in the interior. The shell has one end bored with a through hole communicating with the chamber and having a lengthwise projection on the inner wall and a battery box positioned protruding-out on the side wall for fitting batteries therein and a plurality of fixing lugs fixed on the bottom edge, with each fixing lug bored with an insert hole for a bolt to be inserted therein. Further, an engage base is secured on a doorjamb, having an insert groove inside and two fixing lugs fixed on the opposite sides, with each fixing lug having an insert hole for a bolt to be inserted therein. A fix base is installed in the chamber of the shell, having two engage grooves respectively provided at the opposite sides, and a shaft hole bored in the center and two insert holes positioned oppositely, with a bolt inserted in each insert hole. A motor is positioned in the chamber of the shell, having its spindle inserted through the shaft hole of the fix base. A circuit board is disposed in the chamber of the shell, and an actuating member is installed in the chamber of the shell, provided at one side with a horizontal projecting stud having a lateral insert hole inside and a vertical threaded hole in the wall to communicate with the lateral insert hole for receiving a bolt therein. The actuating member further has two projections respectively fixed on the opposite walls, a coupling groove formed in the opposite walls of the two projections and two cut slopes respectively provided at the opposite walls of the coupling groove. A passive member is fitted in the chamber of the shell to contact the actuating member, having two projections respectively fixed on the opposite walls, a coupling groove formed in the opposite walls of the two projections, two cut slopes respectively provided at the opposite walls of the coupling groove and a deadbolt with a lengthwise groove secured on the one end. Lastly, a spring is fitted around the deadbolt of the passive member.
