[Field of Invention]

The present invention relates to a door lock knob mounted on a lower side of a window inside an automobile door to operate and release a lock of the door, and more particularly, by providing a link device below the door lock knob, thereby preventing vehicle theft. It relates to a fixed structure of the car door lock knob for.

[Prior art]

In general, a door of a vehicle has a structure in which a door frame surrounding a door glass moved up and down by a regulator is attached to a door body in which an outer out panel and an inner out panel are faced to each other at predetermined intervals. The front side of the body is installed as a case type hinged to the body.

In addition, for opening and closing of the door, a locking device is installed at the rear side of the door, and a door striker to which the locking device of the door is inserted and fixed is mounted at the rear end of the door surface of the vehicle body, and the window glass moved up and down. A door lock knob is installed in the door frame at the lower end of the door, and when the knob is pressed, the door is locked.

[Technical problem to be achieved by the present invention]

By the way, in the structure of such a conventional door lock knob, when the driver is moved away from the car after operating the door lock, as shown in FIG. 1, without having a car key by another person, as shown in FIG. By inserting (1) between the upper door frame (2) and the weather strip (3) and pulling the door lock knob (4) upwards, the door is unlocked and the valuables inside the vehicle or the vehicle are stolen. there was.

Accordingly, the present invention has been made to solve the above-described problems, by providing a link device at the lower end of the door lock knob, thereby allowing the lock knob to lock together when the door lock is operated, thereby preventing theft. It aims to prevent.

[Configuration and Function of Invention]

In order to achieve this object, a hole penetrated horizontally in the lower portion of the lock knob; A rod extending downward from a lower end of the lock knob; A key rod arranged side by side of the rod and connected to the locking device; A key cylinder having a lower end hingeably coupled to an upper portion of the key rod, and a crossing portion of which is hingeably fixed; A linkage device provided at a lower portion of the lock knob and opened in the vicinity of both through holes of the lock knob, and having a three hinge portions arranged at a right side thereof; It extends from the upper end of the link device, to provide a fixing structure of the vehicle door lock knob characterized in that it comprises a connecting portion hingedly coupled to the upper end of the key cylinder.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In this embodiment, the same reference numerals are assigned to the same parts as those cited in the related art, and will be described again to avoid duplication of description. I never do that.

FIG. 2 is a schematic view showing the opening and closing structure of the door lock knob 4 according to the present invention. According to the present invention, a hole 5 penetrating horizontally is formed in the lower portion of the lock knob 4. A rod 6 extends downward at a lower end of the lock knob 4, and a key rod 7 connected to a locking device is arranged side by side on the side of the rod 6, and an upper portion of the key rod 7 is disposed. The lower end of the "-shaped key cylinder 8" is hingedly coupled, and the key cylinder 8 is hingedly fixed at the intersection of the "-shape, and a rectangular link is provided below the lock knob 4. (9) is provided and opened near both through holes (5) of the lock knob (4), in the figure the right side of the linkage (9) the upper hinge portion 12 around the hinge portion (10) Is hinged toward the lock knob 4, and the lower hinge portion 13 It is provided to allow jidoel. In addition, the upper end of the link device 9 extends to the rear side of the drawing, and is hingedly coupled to the upper end of the key cylinder 8 by another connecting part 11.

By this configuration, when the driver operates the locking device with a key, the lock knob 4 is lowered, and the key cylinder 8 portion is hinged in the state indicated by the solid line in the state indicated by the dotted line, so that the lower key rod ( 7) the locking device is operated by pulling the upper part upward, and the connecting part 11 connected to the upper part is pushed to the left side of the drawing, so that the three hinge parts 10, 12, 13 on the right side of the link device 9 are provided. ), The opening of the link device 9 enters the through hole 5 of the lock knob 4, thereby locking the lock knob 4, and vice versa upon release.

[Effects of the Invention]

As described above, according to the locking structure of the lock knob according to the present invention, by providing a link device that locks the lock knob together with the lock of the door in the lower portion of the lock knob, to prevent theft It is effective.

The present invention has been illustrated and described above with respect to certain preferred embodiments, but the present invention is not limited to the above-described embodiments, and the present invention belongs without departing from the spirit of the invention as claimed in the claims. Anyone with ordinary knowledge in the field will be able to make various changes.
