Description

Technical Field

[0001] This invention relates to a cabinet door lock, which can be locked or unlocked by a specified locking mechanism. Background Technology

[0002] A cabinet door lock is a mechanical device used to lock the doors of various types of cabinets, lockers, or storage spaces. Primarily used for storing personal belongings or for security purposes in public places, it includes a mechanism that, along with a handle, controls the opening and closing of the door. These locks allow users to lock and open the door and can be designed in different shapes to accommodate various locking schemes.

[0003] Conventional cabinet door locks primarily use a rotary knob and a locking bar to lock and unlock the door. When the user rotates the knob, the rotary knob rotates, and the locking bar moves back and forth to lock or unlock the door. These locks are widely used due to their relatively simple structure and low price.

[0004] However, in traditional methods, the locking lever moves as the rotating plate rotates. In this case, the locking lever may not have sufficient travel (length), and the locking may not be complete. In particular, if the door is not fully aligned, the lock may not function properly, resulting in weaker security.

[0005] Furthermore, the limited rotation angle of the rotating plate shortens the movement time of the locking lever, frequently leading to door lock malfunctions. This is especially true if there are installation errors.

[0006] Therefore, the magnetic field of a magnet is needed instead of mechanical parts to lock and unlock the locking system.

[0013] The problem that the invention aims to solve

[0014] The present invention aims to solve the above-mentioned problems by using a magnetic field of a magnet instead of mechanical parts to solve the problem of locking and unlocking.

[0015] Methods for solving problems

[0016] In the cabinet door lock of the present invention, a shell with a defined internal space is provided, and one side is open. The opening consists of an opening portion of the shell in the form of a rectangular frame, a rotary hinge coupled to one side of the opening, a door portion for opening and closing the opening portion of the shell when rotating, a door portion provided on one side of the opening, and a second magnetic device provided inside the door portion, but combined with a first magnetic object by magnetic force. The opening consists of two vertical rods and two horizontal rods. The rotary hinge is coupled to any one of the vertical rods, and the other vertical rod is equipped with multiple springs to reduce the speed at which the door portion approaches the opening.

[0017] Next, the cabinet door lock is arranged parallel to the rotating hinge, but the flip hinge also includes a division in the Z direction relative to the imaginary line. The door portion is a pivot door located between the rotating hinge and the flip hinge. The flip hinge is divided into a rotating flip door by the pivot door by the axis of rotation. The cabinet door lock is located on the inside of the door portion, but is arranged in a form where the flip door and the pivot door intersect. The flip door is characterized by a flip stop to prevent the flip hinge from rotating inward by the axis of rotation.

[0018] Next, the cabinet door lock is set to extend from the side of the housing by a predetermined length. A rotation limiter restricts the pivot door from rotating to a maximum angle of 180 degrees. A third magnetic device with a certain magnetic force is set on the side of the rotation limiter, and a fourth magnetic device is set on the side of the flip door and coupled to the third magnetic device. The length of the rotation limiter extending from the housing is characterized by the length of the pivot door at the maximum angle. At the same time, the flip door rotates around the flip hinge. The third magnetic device and the fourth magnetic device are in contact. The second magnetic device is made of magnetic material, and the first magnetic device is composed of an electromagnet that is energized. The magnetic force is adjusted according to the strength of the current. The cabinet door lock is characterized by including a power supply unit for supplying power to the electromagnet and a control unit for controlling the power supply unit.

[0019] Next, the cabinet door lock also includes a temperature measuring device. When a predetermined pressing pressure and a set temperature within the range of 35-38°C are detected, a power supply signal is provided to the control unit. When the temperature measuring device provides a power supply signal, the control unit provides current to the electromagnet. The temperature measuring device includes a temperature sensor in the form of a recess located at the center of the second vertical part. A finger piercing hole is provided on one side of the flip door, but at the same height as the body temperature sensor. A puncture sensor is provided inside the finger piercing hole. In the body temperature detection sensor, a first signal is generated when pressing pressure and a set temperature are detected. The puncture detection sensor generates a second signal when it detects an object passing through the finger piercing hole. In the temperature measuring device, when the first and second signals are generated simultaneously, a power-off signal is provided to the control unit. When only the first signal is generated, a power supply signal is provided to the control unit.

[0068] Figure 2 yes Figure 1 Examples of implementations.

[0069] According to the cabinet door lock of the present invention, a defined internal space is provided, one side of which is provided in the form of an open housing 100, which includes an open portion of the housing 100, but is composed of an opening in the form of a rectangular frame 600, a rotating hinge 210 coupled to one side of the opening 600, and the opening 600 is combined in the form of rotating to the rotating hinge 210, but the door portion 300 is used to open and close the opening portion of the housing 100 when rotating, and a first magnet 410 is provided on one side of the opening 600 and the inside of the door portion 300, but it may include a second magnet 420 coupled to the first magnet 410 by magnetic force.

[0070] The opening 600 consists of two longitudinal members 610 and two transverse members 620, with a rotary hinge 210 coupled to any one of the longitudinal members 610, and the other longitudinal member 610 is equipped with a plurality of springs 650, characterized in that the approach of the door portion 300 to the opening 600 is slowed.

[0071] Here, the longitudinal member 610 can be divided into a first vertical part 611 and a second vertical part 612.
