The present invention relates to a fixing device for a door lock clasp plate that can easily attach the door lock cladding plate to the door frame frame.

When attaching the door lock clasp to the door frame, it should be attached flat without the outer surface and irregularities of the frame, so it is cut to the door frame frame to which the clasp will be attached, and the clamping plate is fixed to the inside of the frame by bolts. Since the pieces are mainly attached by welding, the work is difficult and the door frame frame is damaged by welding.

In the present invention, such a defect is improved, and a rear support plate having a hook insertion hole formed inside the cutout portion into which the frame decision plate of the frame is to be fitted is caught at the top, bottom, and left ends inside the cutout, and is spaced from the right frame. In the gap, the upper and lower parts are joined by bolts so that the rear end of the agency board bent at right angles is sandwiched, and the rear support plate is fixed as a bolt of the support supported at both bent ends at the rear of the frame at the rear part. It can be separated as the upper and lower bolts, and in the place can be simply replaced by the bolt to the decision plate as described in detail according to the drawings as follows.

The insertion hole 11 of the locking chain is formed in the cutout plate size of the frame 1, and the upper and lower rear support plates 10 having bolt holes 12 and 12 'are formed on the upper and lower sides. The lower end is caught by the inner surface of the incision 2, and the rear end 21 is bent at right angles to the same size as the decision plate by opening the gap 4 between the width and the width between the frame on the right side. Insert the substitute plate 20 so as to be sandwiched in the gap and planar with the frame at the incision, and joined as the bolt 5 to the upper and lower bolt holes 22, 22 ', 12 and 12'. As the bolt 31 of the support 30 which is horizontally supported inside the two bent ends 3 and 3 'of the rear of the frame, the rear support plate 10 is fixed to the front from the top and the bottom to act as a substitute after the door frame construction. The plate 20 is separated from the rear support plate by the upper and lower bolts 5, and the check plate 6 is replaced at this position. Burr.

The cutout plate of the door lock is inserted into the outer surface of the frame so as to be flat with the outer frame of the frame according to the size of the cutout plate, and the inside of the cutout has a hook insertion hole formed in the center. The upper, lower, and left ends of the support plate 10 are caught by the inner surface of the incision, and the bent rear end 21 of the substitute plate 20 is sandwiched in the gap gap 4 on the right side so as to sandwich the upper and lower bolt holes. (22) and (22 ') as bolts (5) to the bolt holes (12) and (12') of the rear support plate and the incision part in a planar manner, and a posterior plate at the rear part of both sides of the bend end behind the frame. Since the upper and lower parts of the rear support plate were closely attached to the front as the bolt 31 of the support 30 supported laterally, the rear support plate attached to the front and the lower support plate with bolts from the front was firmly fixed to the inner side of the cutout of the frame. Door frames That when installing the building after construction, the door lock is in a simply fixed sikilsu as upper and lower bolts to upper and lower bolt isolated as a proxy plate 20 joined to the rear base plate and replacing the top plate chain in its place.

Claims (1)
