A look at the operational effects of the dial lock device for easy password change according to the present invention configured as described above is as follows.

First, in the dial lock device 100, in which the password can be easily changed according to the present invention, the lever unit 20 rotates in a state in which the password is set using the dial 31 constituting the dial unit 30, as in the conventional locking device. Thus, the door can be locked and unlocked, and if the password of the dial 31 constituting the dial 30 does not match in the locked state of the door, the lever 20 operates so as not to rotate.

Here, when the lever part 20 is closed and the password of the dial part 30 is not correct, the closed position surface 26 formed on the cylinder 22 constituting the lever part 20 is the dial part 30 It is disposed at a position where the shaft 32 constituting the is formed.

Here, the closing position surface 26 formed on the outer circumferential surface of the cylinder 22 of the lever unit 20 is configured to protrude more than the open position surface 25, and when positioned on the upper side of the shaft 32, the engaging portion ( 40) to press the upper surface of the hook body 42 so that the hook part 40 is pressed by the closing position surface 2 and maintains a state of being pressed downward.

Here, a shaft insertion hole 42a is formed inside the locking part body 42 constituting the locking part 40 so that the shaft 32 constituting the dial part 30 moves upward and downward.

In particular, an operation limiting groove 42b is formed in the locking part body 42 constituting the locking part 40, and the password changer body constituting the password change unit 50 is formed in the operation limiting groove 42b ( 51) of the operation limiting portion 51c maintains a coupled state by the third spring S3, so that the engaging portion 40 and the dial 31 and the shaft ring lock 32 of the dial portion 30 are connected to the second spring. (S2) to prevent upward movement, the length in the vertical direction of the operation limiting groove 42b of the locking body 42 constituting the locking portion 40 is the password change unit 50 It is formed larger than the thickness in the vertical direction of the operation limiting portion (51c) of the password changer body (51) configured, so that when the locking portion (40) is pressed downward as described above, the first spring (S1) The shaft 33 protrudes from the locking part body 42 and is disposed on the step 26a of the closing position surface 26 constituting the lever part 20, thereby limiting the rotation of the lever part 20 and locking the door. It works to maintain the state.

On the other hand, when the user matches the password through the dial 31 of the dial unit 30, the second locking groove 32b of the shaft ring lock 32 constituting the dial unit 30 and the second locking of the shaft 33 The jaws 33a are arranged on the same line, so that the shaft 33 can move downward.

Therefore, when the user rotates the lever part 20 after matching the password, the shaft 33 located on the closing position surface 26 is moved downward by the closing position surface 26 and the cylinder 22 and rotates. The door lock is unlocked when the opening position surface 25 of the lever unit 20 rotates in this way moves to the upper side of the shaft 32.

Here, the locking portion 40 is pressed by the closed position surface 26 of the lever unit 20 when the door is in the closed state, but presses when the open position surface 25 is positioned above the shaft 32. This is not done so that the shaft 32 remains unexposed to the outside.

As described above, when the lever part 20 is rotated to open the door, the locking part 40 is no longer pressed, and the shaft 32 is opened by the stopper 51b of the password change part 50. This is because the third locking jaw (33b) of the ) is prevented from moving upward any more, and as a result, the shaft 33 acts to contact the lever unit 20 only when the door is locked, causing the shaft 32 due to repeated use. It is possible to obtain an action effect that can prevent damage to.

Meanwhile, when the door is opened as described above, the password of the dial unit 30 can be easily changed by operating the password change unit 50 .

Looking at the password change process in more detail, a shaft ring lock 32 is disposed inside the dial 31 constituting the dial unit 30, and the shaft ring lock 32 is placed in the first locking groove 31a of the dial 31. When the dial 31 is rotated normally by maintaining the first locking jaw 32a of the coupled state, the dial 31 and the dial ring lock 32 rotate together.

In addition, the password change unit 50 maintains a state in which the operation limiting portion 51c is coupled to the operation limiting groove 42b of the locking portion 40 by the elastic force acting by the third spring S3 to keep the locking portion ( 40) and the shaft ring lock 32 do not rise even if the elastic force of the second spring S2 acts and maintains the current state.

On the other hand, when the user presses the password change unit 50 to change the password of the dial unit 30, the operation limiting unit 51c of the password change unit 50 in the operation limiting groove 42b of the locking unit 40 Is separated, and due to this, the shaft ring lock 32 of the locking part 40 and the dial part 30 is moved upward by the second spring S2, so that a state in which the password can be changed is achieved.

Here, the password change unit 50 in the present invention is disposed together with the locking portion 40 at the position where the shaft 32 is formed.

Therefore, in a state where the password changing unit 50 and the locking unit 40 are disposed at the same position in the vertical direction, the operation limiting unit 51c abuts on the operation limiting groove 42b formed at the rear to lock the structure. Therefore, compared to the prior art, the operation is made intuitive, so that the effect of preventing damage to parts and preventing malfunctions can be obtained.

In addition, in the present invention, it is possible to obtain an effect of preventing the rotation of the lever part 20 naturally when the user does not want it through the anti-rotation spring 70.

That is, in the anti-rotation spring 70, the first and second horizontal bars 71 and 72 are coupled to the locking bar coupling groove 12a of the locking bar 12 constituting the main body 10 to maintain elastic force. First and second elastic parts 74 and 75 that come into contact with the cylinder 22 of the lever part 20 and limit the rotation of the cylinder 22 are part of the second horizontal bar 72 in a coupled state so as to be able to do so. is formed

Therefore, when a force for rotating the lever part 20 is applied by the user, the cylinder 22 rotates while pushing the inclined elastic part of any one of the first and second elastic parts 74 and 75, and then a certain amount of rotation is completed. Then, the elastic part of any one of the inclined parts of the first and second elastic parts 74 and 75 acts to rotate the lever part 20 to the position desired by the user, so that the user does not want it, that is, the user In a state in which the lever unit 20 is not operated, the lever unit 20 is prevented from being rotated, so that the user's convenience can be improved.
