Abstract

The present invention relates to a rotating body rotating in the center of the lock operation

Conventionally, the rotational structure is complicated, and the key-key insertion hole is formed in a straight rectangle, and there are many problems such as inserting a straight driver and hitting it with a hammer so that the operation piece 15 falls and the lock is broken.

The present invention forms a key hole (2) insertion hole of the rotating body (3) as a circular hole (7) (7 '), and forms an arbitrary rotating body (6) which rotates arbitrarily at the front end of the rotating body (3), It is designed to be simple in construction, easy to mass-produce, mass-saving, and to prevent damage to the lock by preventing the opening and closing operation of only the rotational body entry part of the lock operation port.

Description

Rotating body for lock actuator with circular key key insertion hole and arbitrary rotating body {AAAAA}

The present invention relates to a rotating body and a key in a lock operation mechanism that rotates when the key is inserted and rotated. Particularly, the key key insertion hole formed in the rotating body is formed into a circular hole, so that ordinary key insertion is difficult. The first half of the rotating body relates to a circular inserting hole formed so that the key can be arbitrarily rotated even if the key is not matched, and a rotating body for the lock operating device formed with an arbitrary rotating body.

Conventionally, the key rod insertion hole is formed as a straight rectangular hole on a rotating rod to which a plurality of operating pins and springs are mounted, so that any key can be easily inserted. When the rotation opening and closing, or when opening and closing is not easy to insert a straight-type driver, there was a problem that the turning side operating piece (backset pin) is opened and closed while inserting a straight-type driver and hitting with a hammer.

An object of the present invention is to solve the above problems, and in particular, by forming the key insertion hole of the rotating body into a circular hole so that only the circular key of the present invention can be inserted and closed, and the first half of the rotating body is formed to be rotated at random. Even if a key, wire or skewer is inserted into the rotating body insertion hole, the first half of the rotating body rotates randomly and the rotating body does not rotate, so the opening and closing operation is difficult and the key insertion hole is a circular hole. The objective is to prevent the lock from being broken by inserting a straight-type driver while hitting it with a hammer.

The rotating body 3 mounted to the center of the lock actuating mechanism 1 and to which the actuation piece 15 is connected has a track shape following a circular insertion hole 7 'in the center of the insertion groove 17 and the locking ring jaw 9. The insertion hole 12 is formed, and the fixing hole 11 or the long hole 13 is formed at one side of the insertion groove 17 of the rotating body 3, so that the circular insertion hole 7 and the round end recess 8 are formed. The arbitrary rotation body 6 formed is inserted into the insertion groove 17, and then the fixed locking pin 10 or the washer 14 is inserted into the fixing hole 11 or the long hole 13, and fixed at any time. The entire body 6 is formed integrally with the rotational body 3 and is formed so that it can be arbitrarily rotated in the first half, and the key key 2 is formed with an insertion part as a round bar 4, and an incision surface 5 at the end side ( 5 ') is a rotating body for a lock operation mechanism formed with a circular key key insertion hole and an arbitrary rotating body, characterized in that formed in a track shape.

The operation of the present invention configured as described above inserts the annular recess recess 8 of the arbitrary rotating body 6 into the recess 17 of the pivoting body 3 as shown in FIG. 13) When the fixed locking pin 10 or the washer 14 is inserted into and fixed, the arbitrary rotating body 6 is mounted on the entire exposed part of the rotating body 3 and the recessed end recess 8 of the arbitrary rotating body 6. Since the fixed locking pin 10 is inserted into the locked state, the arbitrary rotating body 6 and the rotating body 3 can be arbitrarily rotated without being separated.

In addition, in order to operate the lock operating mechanism (1) equipped with the present invention rotational body (3), the insertion part is formed of a round rod (4) and the incision surface (5) (5 ') is formed on the end side to form a track-type insertion part If the key key 2 to be formed is to be inserted, the insertion portion of the key key 2 passes through the circular holes 7 and 7 'and then is inserted into the track-type insertion hole 12 formed at the end side. When the key 2 is rotated, the operating piece (back set pin) 15 connected to the connecting portion 16 rotates while the pivoting body 3 rotates.

Therefore, any key or a driver having a straight shape cannot be inserted into the circular insertion hole 7 of the rotating body 3 and cannot be opened and closed arbitrarily, and skewers, etc., are placed on the first half of the rotating body 3. Since only the arbitrary rotating body (6) rotates even if it is inserted and rotated, it is recognized that the opening and closing operation does not work when rotating with the rotating body (3), and thus the arbitrary opening and closing operation is impossible.

In addition, since it is formed as a circular insertion hole, it is impossible to insert a conventional straight-type driver, etc., thus preventing the act of breaking the lock by inserting the driver and hitting it with a hammer.

As described above, the key key and the rotating body of the present invention have a simple configuration, which facilitates mass production, greatly reduces the production cost of the rotating body of a complicated configuration, prevents any opening and closing operation, and prevents the insertion of a screwdriver, etc. It is a very useful design to prevent the lock damage.
