Abstract

A remote control lock structure. The lock structure includes a receiving box, a locking member, a transmission mechanism, an electric circuit element and a cover. The locking member is placed in the receiving space aligned with a screw hole of a positioning block with a round hole on the receiving box. An axle rod is extended into and out of the round hole, and one end of the axle rod is connected to a main gearing wheel of the transmission mechanism. The main gearing wheel is connected at its lateral sides with the two power transmission wheels, and two power motors are connected with the electric circuit element which provides electric power to activate one of the power motors, thereby one of the two power transmission wheels and the main gearing wheel are driven to rotate. The axle rod further drives the locking rod to rotate to make the latching rod on the front end of the locking rod extend out and retract in between the screw hole and the round hole.

Claims

1. A remote control lock structure comprising:

a receiving box, a locking member, a transmission mechanism, an electric circuit element and a cover;

wherein said receiving box has therein a receiving space to receive said locking member, said transmission mechanism and said electric circuit element, said receiving space is provided on one end thereof with a round hole, and said receiving box is covered with said cover thereover;

said locking member is provided in said receiving box, and includes a positioning block which has therein a screw hole, said screw hole allows a locking rod to screw therein, said locking rod is provided on one end thereof with an axial hole;

said axial hole is provided for extending of an axle rod therein, and said axle rod is provided thereon with a stop block;

said transmission mechanism is connected to one end of said locking member and is provided in said receiving box;

said transmission mechanism is provided thereon with a main gearing wheel, two power transmission wheels are provided at the two lateral sides of said main gearing wheel, said two power transmission wheels are provided with two power motors;

said electric circuit element provides electric power for said power motors and is also provided in said receiving box;

said locking member is placed in said receiving space of said receiving box to make alignment of said screw hole of said positioning block with said round hole;

said axle rod is connected on one end thereof into said main gearing wheel of said transmission mechanism;

said electric circuit element provides electric power to activate one of said power motors, thereby a corresponding one of said two power transmission wheels is driven to rotate, said main gearing wheel and said axle rod thus is in turn driven to rotate, said axle rod further drives said locking rod to rotate in said screw hole, and a latching rod on said locking rod is extended out and retracted in between said screw hole and said round hole.

2. The remote control lock structure as claimed in claim 1, wherein said locking rod of said locking member is driven by said axle rod to rotate forwards and to render said locking rod to extend and move forwards, when a sensing piece of said locking rod is moved to the position in a front sensing device, said electric circuit element activates said one of said power motors to operate;

when said locking rod is driven by said axle rod to rotate rearwards and to render said locking rod to move rearwards and retract, said sensing piece of said locking rod is moved to the position in a rear sensing device, now said sensing piece of said locking rod abuts against said stop block of said axle rod, and said electric circuit element stops operation of said power motor.

3. The remote control lock structure as claimed in claim 1, wherein when in operation of said remote control lock, said electric circuit element only drives one of said power motors to rotate, and in turn drives said corresponding one of said two power transmission wheels to drive said main gearing wheel, the other of said power motors and the other of said power transmission wheels are ready for use;

when said one of said power motors faults or is out of work, said electric circuit element drives said other power motor to transmit power through said other one of said power transmission wheels to drive said main gearing wheel, in this way, said remote control lock has two motors for driving.

4. The remote control lock structure as claimed in claim 1, wherein said remote control lock is mounted at a mutual juxtaposed position of a door panel and a door frame, so that said remote control lock is hidden in said door panel and is not easy to be destroyed.

5. The remote control lock structure as claimed in claim 1, wherein said receiving box has therein a receiving space which is provided therein with a positioning ring, a recess provided on said axle rod is provided for said positioning ring, when said axle rod is placed in said receiving space, said recess is used to engage said positioning ring, so that said axle rod is pivotally connected to said positioning ring.

6. The remote control lock structure as claimed in claim 5, wherein a positioning seat is provided in the rear of said positioning ring and is provided therein with receiving recesses, said positioning seat is further provided on the front side thereof with a limiting hole;

said receiving recesses of said positioning seat are provided for placing therein said power motors of said transmission mechanism, said limiting hole is provided for inserting therein one end of said axle rod.
