Description

Door locks to prevent theft

The present invention relates to a door locking device for preventing theft, and in particular, to prevent theft of the vehicle by forcibly releasing the locking state of the door by using a stolen tool from the outside, to prevent theft of the vehicle door lock Relates to a device.

In general, a conventional vehicle has a locking device on the inside of the door, and an open handle is installed on the outside of the door to open the door using the open handle from the outside of the vehicle. Is shown in FIG. 1.

As shown in Fig. 1, the conventional door latch structure is provided with a latch 3 having a lock lever 2 in the center portion inside the door 1, and the door 1 on the upper portion of the latch 3. The outer handle rod 4 connected from the outer handle (not shown).

In addition, the center portion is bent to form a hinge hole (5), and the lock control lever (7) having an open protrusion (6) is installed on one side, the outer handle rod (4) and the hinge hole (5) butt hinge (8) engage, with the open protrusion 6 positioned above the lock lever 2 so that the open protrusion 6 of the lock control lever 7 locks when the outer handle rod 4 is operated. Install so that lever (2) can be pressed.

The reason for installing the lock control lever 7 is that when the door 1 is locked with a key, the lock control lever 7 is rotated so that the open protrusion 6 is separated from the upper part of the lock lever 2. It is to be so that the door (1) can not be opened.

Looking at the operation state of the conventional door latch configured as described above are as follows.

When the door 1 is opened, when the passenger pulls the outer open handle, the outer handle rod 4 is lowered, and the lock control lever 7 coupled to the outer handle rod 4 by the hinge 8 is lowered.

Therefore, the open protrusion 6 formed at one end of the lock control lever 7 lowers the lock lever 2 of the latch 3 to release the locked state of the door 1, thereby opening the door 1. It can be.

In addition, when the vehicle is parked, when the lock control lever 7 is rotated using a key, the lock control lever 7 is rotated about the hinge 8 so that the open protrusion 6 is locked by the lock lever 2. Since it moves away from the top of the), the door 1 is not open.

However, in the conventional door latch constructed as described above, since the gap between the latch 3 and the lock control lever 7 is wide, it is impossible to prevent the intrusion of the stolen tool penetrating from the window glass part by exposing the locking part. There was a problem that could not prevent theft of the vehicle.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, to provide an anti-theft device of the door latch that can prevent theft of the vehicle by preventing the intrusion of the stolen tool from the outside. There is this.

In order to achieve the above object, the present invention is provided with a latch installed inside the door and having a lock lever at the center, an outer handle rod installed at the upper part of the latch and connected from an outer handle of the door, and bending the center portion to the outer handle. A lock control lever hinged to the rod and having an open protrusion to press the lock lever on one side, and a plurality of protrusions provided on an inner circumferential surface of the lock control lever and the latch provided between the lock control lever and the latch and coupled to the outer handle rod; The coupling hole is formed on the upper portion, and the lock lever is inserted into the lower portion to form a long hole so that it can flow up and down, and characterized by consisting of a bracket formed a wing on one side.

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

As shown in FIGS. 2 to 3, the present invention provides a latch 20 having a lock lever 21 at a central portion inside the door 10, and the upper portion of the latch 20. Install an outer handle rod 30 connected from an outer handle (not shown).

In addition, the lock is bent to the center portion and the outer handle rod 30 and the hinge 31 is coupled to form an open protrusion 41 on one side so as to press the lock lever 21 when the outer handle rod 30 is operated. Install the control lever 40.

An anti-theft bracket 50 is installed between the lock control lever 40 and the latch 20.

The bracket 50 is coupled to the outer handle rod 30 and the hinge 31, and a plurality of protrusions on the inner peripheral surface to prevent the bracket 50 from flowing up and down when the lock control lever 40 is lowered A coupling hole 51 having 52 is formed in the upper portion.

In addition, the lower portion of the bracket 50, the lock lever 21 is inserted to form a long hole 53 so that it can flow up and down, and wings 54 on one side to prevent the stolen tool from the outside to enter ).

Looking at the operation of the present invention configured as described above are as follows.

When the door 10 is opened, when the passenger pulls the outer open handle, the outer handle rod 30 is lowered, and the lock control lever 40 coupled to the outer handle rod 30 by the hinge 31 is lowered.

When the lock control lever 40 is lowered as described above, the open protrusion 41 formed at one end of the lock control lever 40 is pushed down by pressing the lock lever 21 of the latch 20 to lock the door 10. Since it releases, it will be able to open the door (10).

In addition, when the door 10 is locked, when the lock control lever 21 is rotated using a key, the lock control lever 21 is rotated about the hinge 31 so that the open protrusion 41 is locked. Move so as to deviate from the upper part of the lever 21.

Therefore, the door 10 cannot be opened. At this time, since the bracket 50 is installed between the latch 20 and the lock control lever 40, a gap is formed by the bracket 50 and the blade 54. This prevents theft tool from infiltrating the window glass.

As described above, the present invention is to provide a door lock device for preventing theft, it is a very useful design to prevent theft of the vehicle to prevent the theft of tools stolen from the outside.
