The present invention is a lock used to open and close furniture or desk assembly, and the connection part of the key insertion pipe is not a normal pipe. Pressing both ends with protrusions into the key insertion tube incision grooves using a type iron plate causes the projections to be firmly interlocked because they are not inserted into the indentation grooves, and the back end of the copper plate is inserted into the center hole of the known rotating cam. The bent piece on the rear end of the iron plate is bent outside the + hole to prevent the iron plate from falling off and the stone plate of the operating plate is connected to the locking protrusion of the rotary cam. Since the circular operating plate supports the pivoting cam which rotates a lot, the pivoting cam does not deviate from the track, so that the defective product does not occur. The conventional lock can be expensive because the length of the key insertion tube made of the transverse member is long. There is only one that is uneconomical and shortens the length of the key insertion tube, As it is replaced by, it brings about a little raw material saving, but it is like a conventional one, and the bending piece supports the rotating cam at the rear of the connector, which results in supporting a part of the rotating cam, resulting in a lot of defective products due to departure from frequent tracks. There was this.

The present invention has been devised by correcting the above-described drawbacks.

A projection (6) (6 ') is formed at each of the cutting grooves (3) on one side and the indentation grooves (4) on the outer circumference of the key insertion pipe (2) which is horizontally inserted into the cylindrical pipe (1) of the conventional lock. The rear end has a bending piece (7) In the fastening of the type connecting plate 5, the tip end of the connecting plate 5 is inserted into the cutting groove 3 of the key inserting tube 2 and pressurized so that the projections 6, 6 'are inserted into the key inserting tube 2 (+) Hole (11) is drilled in the center hole of the known rotating cam (8) having a locking projection (9) so as not to be separated from each other by being caught in the recess groove (4) of The plate 10 is inserted and inserted into the rear end of the connecting plate so that the bent piece 7 of the rear end does not come out of the + -shaped hole 11 of the operating plate 10 so as not to be pulled out. It is a structure which is connected with the gripping protrusion 9 of the rotation cam 8. As shown in FIG.

The present invention configured as described above is connected to the key insertion pipe (2) is not a cylindrical tube connection portion as conventional Since it is a type connecting plate (5), the raw material can be greatly reduced, and a key insertion pipe (2) and a working piece (10) integrally connected to the connecting plate (5) are inserted into the center hole of the rotating cam (8). In accordance with the rotation of the key inserted into the insertion tube (2), the key insertion tube (2) and the operating plate (10) is rotated together, so that the projections (12) of the operating plate (10) is a locking projection (9) of the rotating cam (8). ), The rotating cam (8) is also moved in the same direction, so that the quick and easy opening and closing operation is not only performed, but also the tip projections (6) and (6 ') of the connecting plate (5) are cut out of the key insertion pipe (2). It is pressurized into the groove (3) and inserted into the recessed groove (4) so that it can be used for a long time because it is hard to come out. The circular cam (8) is supported by the circular operating plate (10) so that the rotary cam (8) is supported. As the supporting area is widened, the rotating cam (8) does not deviate from the orbit even during frequent rotation, so there is no defective product. Well, of course, the price of the product is remarkably inexpensive.

Claims (1)

As shown in the drawing, the cutting grooves 3 and the indentation grooves 4 are formed on the outer periphery of the key insertion pipe 2 which is horizontally inserted into the cylindrical pipe 1 of the conventional lock. ') Has a bent piece (7) In the fastening of the type connecting plate 5, the tip end of the connecting plate 5 is inserted into the cutout groove 3 of the key insertion pipe 2 and pressurized so that the projections 6, 6 'are inserted into the key insertion pipe 2 (+) Hole (11) is drilled in the center hole of the known rotating cam (8) having a locking projection (9) so as not to be separated from each other by being caught in the recess groove (4) of Insert the operation plate 10 and insert it into the rear end of the connecting plate 5 so that the bending piece 7 at the rear end does not come out of the + -shaped hole 11 of the operation plate 10 so as not to be pulled out. A lock for furniture, characterized in that (12) is connected to the locking projection (9) of the rotating cam (8).
