Description

Locking device to prevent rotation of dialing in opening states

The present invention relates to a locking device installed in a locker and configured to open and close a door by a dial number key and a key, and more particularly, to prevent rotation of dialing in an open state of the locking device, and to lock the guide member and the It relates to a locking device capable of preventing rotation of dialing in an open state configured to be converted to a 'reset state' in which rotation of dialing is possible only when a locking member is removed.

"Dial lock for lockers" is introduced in Korean Patent No. 10-1509537 (registered on April 1, 2015). The dial lock for the locker has an off-duty search operation means installed in a diagonal direction in one side of the rear side of the main body to correspond to the detection hole formed at the lower end of the connecting rod that is fitted to each of several dials, but an operation uneven member that is transferred in a straight line by an operation pin The lower end of the connecting rod body by rotating the connecting rod body together with the dial while the pin tip is in contact with the outer surface of the connecting rod body through the interlocking action of the detection pins, which are pressed or released by the protrusion of the The pin tip of the detection pin is put into the detection hole formed on one side, and it has a structure to find out the corresponding dial number.

However, the dial lock for the locker has a disadvantage in that the password cannot be retrieved if the detection pin is lost while the password is forgotten.

In addition, Korean Patent No. 10-0558118 (registered on February 28, 2006) discloses a "reset device for a dial lock" (hereinafter referred to as 'prior art 1'). The reset device of the dial lock includes a main body attached to the door, a dial bundle having a lock rod installed in the main body and capable of moving when the password is matched, and a locking rod of the dial assembly to operate the latch piece. In the known dial lock comprising a rotor, a key bundle equipped to operate the rotor as a master key, and a lever for operating the key bundle, a separate reset groove is provided in the rotor, A reset bundle, which has a protrusion of the rotor extending outside it, is loaded into the body with a spring, and only when the button of the reset bundle is pressed, the rotor can move to the “reset” position, and at this time, password reset is possible.

However, the reset device of the dial lock of the prior art 1 has a disadvantage in that the configuration becomes complicated because a separate reset bundle must be additionally configured.

In order to overcome this problem, in Registered Patent Publication No. 10-1747170 (hereinafter referred to as 'prior art 2'), when the user forgets the password, the user inserts the key into the bundle of keys and turns the handle from the lock position to the number search position. In addition, when the handle is rotated to the number search position, the upper part of the shaft of the dial bundle is inserted into the number search groove of the cylinder, so the user can easily find the password by turning the dial of the dial bundle, and it is possible to retrieve a forgotten password without a separate reset pin or button. We provide a dial lock for lockers that can be found and the password can be reset in the open position.

However, in the prior art 2, components such as a control rod and a press cam must operate organically in order to rotate the cylinder and the rotor, so the configuration and operation are complicated, and there is a problem in that the assembly and cost are increased accordingly.

In order to solve this conventional problem, the applicant of the present application has improved the rotational configuration of the cylinder and the rotor in Patent Publication No. 10-2056895 (hereinafter referred to as 'pre-registered technology') so that it can be operated by simple operation, and the By simplifying, manufacturing and assembly costs can be reduced, and a dial locking device for lockers that is easier to maintain has been proposed.

In the pre-registration technique, in FIG. 1, when a rotary lever (not shown) coupled to the rotor 200 is turned from the locked position to the open position, the guide member 350 is raised by the first spring 370, and the second As the shaft 310 is raised by the spring 380 and the upper end of the guide member 350 and the upper end of the shaft 310 are drawn into the opening groove 13, the second polygonal meshing portion ( 332 is separated from the first polygonal meshing part 322 of the dialing 320, and is converted to a 'reset state after opening'.

Accordingly, the pre-registration technology can set a new password by turning the dialing 320 in the 'reset state after opening', which is the first polygonal meshing part 322 of the dialing 320 and the second polygonal second angle of the dial gear 330. Since the meshing portions 332 are separated from each other, a new password can be set by turning the dialing 320 that can rotate freely. And when the cylinder 100 and the rotor 200 are rotated counterclockwise by 90° by the rotary lever in the open state, the right side of the guide groove 17 is in close contact with the rib 42 and is switched to the locked state.

However, since the 'reset state after opening' of the pre-registration technology is a state in which the dialing can be rotated freely, the dialing is rotated due to the user's carelessness and the password is often forgotten. It was cumbersome to use.

The present invention is to solve the above problems, in order to improve the problem that the dialing collides with another object in the open state of the locking device and rotates regardless of the user's will, thereby forgetting the password, the rotation of the dialing is prevented in the open state It is an object of the present invention to provide a locking device capable of preventing the rotation of the dialing in an open state with an improved structure so that the rotation of the dialing is possible only when the guide member and the locking member are separated into a 'reset state'.

In the locking device capable of preventing rotation of the dialing in an open state according to the present invention, a cylinder coupled to be rotatably coupled to the main body is installed, and the protrusion of the guide member is inserted or separated into the opening groove provided on the outer circumferential surface of the cylinder. In the locking device configured to be able to switch between an open state or a locked state, locking members fixed or separated from each other while moving left and right by the elastic force of a spring are installed on the front surface of the guide member, and in the locked state, dialing is performed to match the password. It rotates freely, and in the open state, the rotation of the dialing is prevented by fixing the guide member and the locking member. In order to reset the password, the dialing is switched to a 'reset state' in which the dialing is freely rotated, and horizontal and vertical insertion grooves and blocking portions are formed on the front surface of the guide member, respectively, and the insertion grooves and blocking portions are on the back surface of the locking member. Its technical feature is that the correspondingly formed insertion portion and the contact portion are inserted and contacted.

According to the locking device capable of preventing the rotation of the dialing in the open state according to the present invention, the guide member is slightly lowered from the inside of the opening groove by the coupling of the guide member and the locking member in the open state of the locking device to rotate the dialing. This is prevented, and when the locking member is moved to the right by the handle in the open state and separated from the guide member, the guide member rises and is inserted into the opening groove, and the dialing is converted to a 'reset state' in which the dialing can be freely rotated to set a new password. Therefore, it is possible to prevent the hassle of using the master machine by forgetting the password as the dialing collides with other objects in the open state and rotates regardless of the user's will, thereby making use and maintenance more convenient.
