Description

[Detailed explanation of the idea] The present invention relates to a lock cylinder mounting device.

Conventionally, the cylinder 2 of the main locking case lock is fixed with a pin 4 as shown in FIG.
A force is applied in the direction of the arrow, and when installing the pin 4, the pin 4 is inserted while pressing the cylinder 2 with a finger.

In addition, as shown in FIG. 2, the attached cylinder 2 had some looseness, making the lock unreliable.

The present invention was devised in view of and to solve the problems of the prior art, and it is an object of the present invention to provide a lock cylinder mounting device that can smoothly assemble the cylinder and mount it reliably and properly. Take the first step.

Hereinafter, an embodiment illustrating the present invention will be described. 0 A is a lock cylinder mounting device, in which the tip end 201 of the cylinder 2 to be inserted into the through hole 101 of the case wood 1 is connected to the cylinder set guide 3 and the pin 4. , and is configured to be attached via a screw guide 5).

The tip 201 of the cylinder 2 has a retaining groove 202 on the upper outer periphery.
is formed, and a retaining projection 203 is formed on the lower outer periphery, and furthermore, a cylinder retaining hole 20 is formed in the upper left and right direction.
4 is penetrated.

The protrusion 3 of the cylinder set guide 3 is attached to the slip-off prevention slide 202.
01 is fitted, and on the other hand, the retaining protrusion 203 is adapted to engage with the lower edge inner side 101a of the through hole 101.

The cylinder set guide 3 has the retaining groove 202 as described above.
A protrusion 301 that fits into the hole 204 and a guide groove 302 for guiding the pin 4 passing through the stopper hole 204 are formed, and one end is pivotally connected to the case body 1 by a pin 7 so that the pin 4 can be rotated clockwise by a spring 6. ).

The protrusion 301 connects the side edge of the guide 3 to the cylinder 2.
It is cut out and curved with approximately the same curvature as the upper outer periphery.

The guide groove 302 is such that the protrusion 301 is connected to the retaining groove 202.
The guide 3 is formed on the pivoting side of the guide 3 so as to be aligned with the stopper hole 204 when the guide 3 is fitted into the guide hole 204 .

The pin 4 is inserted through the through hole 103 of the side plate 102 of the case body 1, passes through the guide groove 302 and the stop hole 204, and its tip 401 abuts the screw guide 5.
In addition, the proximal bent portion 402 is accommodated in a recess 103 a formed around the through hole 103 .

The screw guide 5 is composed of a cylinder 502 having a tip 501 at the end, and when the pin 4 is inserted, the tip 401 is pressed inside (arrow A) and downward (arrow opening) of the case body 1. It is supposed to be done.

Next, the lock cylinder mounting device A configured as described above is
The main effects of this will be explained along with its installation method.

The tip 201 of the cylinder 2 is connected to the through hole 101 of the case body 1.
Insert it inside.

At this time, the upper edge 202a of the tip 201 moves forward while raising the protrusion 301 of the cylinder set guide 3 against the bias of the spring 6 as shown in FIG. The spring 6 inserts and fits the protrusion 301 into the retaining groove 202 .

On the other hand, as shown in FIG.
to be locked.

As a result, the cylinder 2 is no longer retained from the case body 1 and its cylinder retaining hole 204 is aligned with the guide groove 302 of the cylinder set guide 3.

Then, the pin 4 is inserted through the through hole 103 and its tip 401
passes through the guide groove 302 and the stopper hole 204 and comes into contact with the screw guide 5.

At this time, the tip 401 curves up in the direction of the arrow A due to the taper 501 to draw the cylinder 2 to the back of the case body 1, and the tip 401 comes into contact with the outer peripheral surface of the cylinder 502 and curves down in the direction of the arrow. and press the cylinder 2 against the lower end of the through hole 101 of the case body 1.

As described above, in the present invention, a retaining groove and a cylinder retaining hole are formed at the tip of the cylinder, and the case body into which the cylinder is inserted has a protrusion that fits in the retaining groove and penetrating through the retaining hole. A cylinder set guide in which a pin guide groove is formed is pivoted so as to be biased in a direction in which the retaining groove and the protruding part are brought into pressure contact with each other, and the cylinder set guide is attached to the case body where the tip of the pin passing through the hole is located. A screw guide for pushing the tip of the pin inward and downward into the case body was provided protruding from the part to constitute the cylinder attachment device of the lock, so it could be fixed tightly to the cylinder case body. It has the advantage of being simple and quick to operate.
