Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a door lock cylinder mounting device.

[Conventional technology]

To attach the cylinder to the lock case,
- After fitting the cylinder into the mounting hole provided on the side of the lock case as in Publication No. 107041, the reinforcing member is inserted between the cylinder and the lock case while inserting the reinforcing member from the front side of the lock. At the same time, a reinforcing member is fitted into a fitting groove provided on the rear upper surface of the cylinder, and a cutout groove provided on the rear lower surface of the cylinder is inserted into the lower edge of the mounting hole.

[Problem that the invention attempts to solve]

There is a slight gap between both edges of the mounting hole and both sides of the outer circumference of the cylinder, and the outer circumference of the cylinder is oval-shaped, and there are fitting grooves and notches on the arc-shaped upper and lower surfaces that run along the arc-shaped upper and lower surfaces. Since we have set up
The contact between the fitting groove and the reinforcing member is point contact.

Therefore, when the key is inserted into the cylinder and turned, the cylinder rotates slightly together with the key, causing rattling.

In addition, to prevent the above rattling, insert a pin from the front side of the lock, pass the pin through the through hole of the cylinder, and insert and lock the tip and end of the pin into the hole of the lock case. There was also a problem in that it required a lot of work to process.

[Means for solving problems]

In order to solve the above problems, this idea
a through-hole provided in the side surface of the lock case; a cylinder into which the end portion is fitted into the through-hole; and a notched groove provided on the lower surface of the end of the cylinder so as to fall into and engage with the lower edge of the through-hole; A fitting groove provided on the top surface of the distal end of the cylinder, a rocking plate placed on one side of the cylinder in the lock case and rotatably attached to the lock case at its lower end, and a rocking plate connected from the top end of the rocking plate. An engaging piece protrudes toward the top of the cylinder and is provided to fit and lock into the fitting groove when the rocking plate is rotated in the direction of the cylinder, and the fitting piece fits and locks into the fitting groove. A stopper edge provided on the side edge of the rocking plate so as to stop the rotation of the cylinder by coming into contact with the side of the cylinder when It consists of a screw shaft that rotates in a fixed position, with the end for rotation operation exposed on the front side and screwed into a female thread.

[Effect]

After fitting the end of the cylinder into the through-hole of the lock case and inserting a notched groove into the lower edge of the through-hole to engage them, rotate the rocking plate by rotating the screw shaft to fit into the fitting groove. At the same time, the engagement piece is inserted and locked, and the stopper edge is brought into contact with the side surface of the cylinder to stop the rotation of the cylinder.

〔Example〕

In the figure, 1 is a lock case, and a through hole 2 is provided in the side surface of this lock case 1.

Reference numeral 3 denotes a cylinder whose distal end is fitted into the through hole 2, and a cutout groove 4 is provided on the lower surface of the distal end of the cylinder 3 so as to fit into the lower edge of the through hole 2.

In addition, a notch groove 4 is provided on the upper surface of the distal end of the cylinder 3.
A fitting groove 5 is provided parallel to the .

Furthermore, on one side of the cylinder 3 inside the lock case 1,
A rocking plate 7 whose lower end is rotatably supported via a pin 6 of the lock case 1 is provided.

Further, at the upper end of the swing plate 7, there is an engagement piece 8 that protrudes toward the top surface of the cylinder 3 and that fits and locks into the fitting groove 5 when the swing plate 7 is rotated in the direction of the cylinder 3. It is provided.

Further, a female screw 9 rotatably supported at the upper end of the rocking plate 7 is provided, and this female screw 9 has the following features:
A screw shaft 10 is screwed into the front side of the lock case 1, with its end for rotation operation exposed and rotating in a fixed position.

The head of the screw shaft 10 is fitted into a through hole 11 provided in the front wall of the lock case 1, and the collar 12 provided on the head end side of the screw shaft 10 is inserted into the inner surface of the front wall of the lock case. Although the tip of the screw shaft 10 is brought into contact with the inner surface of the rear wall of the screw shaft 10 and rotated at a fixed position, other configurations may be used to rotate the screw shaft 10 at a fixed position.

Further, on the side edge of the rocking plate 7 located on the cylinder 3 side, there is a stopper edge that comes into contact with the side surface of the cylinder 3 and stops the rotation of the cylinder 3 when the engagement piece 8 is fitted and locked in the fitting groove 5. A section 13 is provided.

In addition, in the case shown, there are through holes 2 on both sides of the lock case 1.
2', the cylinder 3 and the thumb turn 14 are respectively fitted, and the respective engaging pieces 8 of the pair of rocking plates 7 facing each other via the connecting plate 15 are fitted into the fitting grooves 5, 5'. However, only the cylinder 3 may be attached.

Further, the female screw 9 and the pin 6 are rotatably supported by fitting between the hole and the protruding shaft of the end surface.

In the figure, 16 is a front plate, and 17 is a long hole provided in the connecting plate 15 so that the screw shaft 10 passes through it.

Next, the method for installing the cylinder will be described. The end portion of the cylinder 3 is fitted into the through hole 2, and the notched groove 4 is inserted into the lower edge of the through hole 2 to engage it.

Next, use a screwdriver or the like to engage the head of the screw shaft 10.
While rotating the swing plate 7 in the counterclockwise direction as shown in FIG. let

〔effect〕

As described above, according to the door lock cylinder mounting device according to this invention, the end of the cylinder is inserted into the through hole, and the notched groove is inserted into the lower edge of the through hole and engaged, and then the screw shaft is inserted. By rotating the rocking plate, the engaging piece is fitted into the fitting groove and locked, and the stopper edge is brought into contact with the side surface of the cylinder.
The rotation of the cylinder can be stopped at the same time as the cylinder is installed.

This eliminates the need for labor-intensive processing to prevent the cylinder from rattling and to stop the rotation of the cylinder by inserting a pin from the front side.
