Description
Technical Field
[0001] The utility model relates to the technical field of locks, in particular to a cabinet door lock with a padlockable handle. Background Art
[0002] A distribution cabinet door lock refers to a lock used on a distribution cabinet or distribution box. A handle-type cabinet door lock is a commonly used cabinet door lock for distribution cabinets used in the field of power transmission and distribution. The lock core is integrated into the handle. When unlocking, the key is inserted into the lock core and rotated to unlock it, then the handle is rotated to open the distribution box. This type of structure requires replacing the entire handle if the lock core is damaged, which is inconvenient. Summary of the Invention
[0003] In view of the deficiencies in the prior art, the utility model provides a cabinet door lock with a padlockable handle.
[0004] The technical solutions provided by this utility model are:
[0005] A padlockable handle-type cabinet door lock comprises a lock seat, a handle, a lock plate, and a lock tongue. The handle is installed on the lock seat, and its lower end passes through the lock seat and is connected to the lock tongue. The handle is provided with a movable groove adapted to the lock plate. One end of the lock plate is hinged to the movable groove, and the other end is a free end that can rotate around a hinge axis. The free end is provided with a through hole for padlocking. The lock plate is provided with a limiting protrusion, and the lock seat is provided with a limiting groove corresponding to the limiting protrusion. When the free end is lifted, the limiting protrusion can be limited to the limiting groove, thereby limiting the rotation of the handle relative to the lock seat.
[0006] A spring is provided between the locking piece and the movable groove, the movable groove is provided with a mounting groove for mounting the spring, and the locking piece is provided with a pressing portion for pressing the spring.
[0007] The upper edge of the locking piece is in a peak shape.
[0008] The locking piece is provided with a limiting portion for preventing the locking piece from excessive rotation.
[0009] Anti-deflection reinforcement ribs are provided on both sides of the movable groove.
[0010] There are two limit slots, corresponding to the handle opening position and the handle closing position respectively.
[0011] The lock seat is provided with a sliding groove for limiting the rotation angle of the handle, and the handle is provided with a limiting protrusion corresponding to the sliding groove.
[0012] The beneficial effects of the utility model are as follows: the cabinet door lock of the utility model has both handle and lock functions, has good functional applicability, can conveniently replace the lock by replacing the padlock, has a simple structure and high compatibility.

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0018] like Figures 1-4 As shown, a padlockable handle-type cabinet door lock comprises a lock base 1, a handle 2, a locking plate 3, and a lock tongue 4. The handle 2 is mounted on the lock base 1, and its lower end passes through the lock base 1 and is connected to the lock tongue 4. The rotation of the handle 2 will drive the lock tongue 4 to rotate synchronously. The handle 2 is provided with a movable groove 5 adapted to the lock plate 3. One end of the lock plate 3 is hinged to the movable groove 5, and the other end is a free end that can rotate around the hinge axis. The free end is provided with a through hole 6 for padlocking. The lock plate 3 is provided with a limiting protrusion 7, and the lock base 1 is provided with a limiting groove 8 corresponding to the limiting protrusion 7. In this embodiment, there are two limiting grooves 8, one corresponding to the handle opening. The handle can be locked in the open position and the handle closed position by limiting the protrusion 7 in the limiting groove 8 when the handle is in the open or closed state. When the handle needs to be locked, the free end is lifted, and the limiting protrusion 7 is limited in the limiting groove 8 as the lock piece 3 rotates. At this time, due to the limitation of the limiting groove 8, the handle cannot be rotated relative to the lock seat 1. The through hole 6 can be used to padlock to prevent unauthorized personnel from operating, thereby ensuring the safety of the electrical cabinet. This cabinet door lock has both handle and lock functions, good functional applicability, and can be easily replaced by replacing the padlock. It has a simple structure and high compatibility.
[0019] In this embodiment, a spring 9 is provided between the locking plate 3 and the movable groove 5. The movable groove 5 is provided with an installation groove 11 for installing the spring. The locking plate 3 is provided with a pressing portion 32 for pressing the spring 9. The installation groove 11 limits the spring to prevent it from shifting when it is compressed, ensuring the accuracy of the force position. The spring provides elastic restoring force for the locking plate 3 to reset.
[0020] In this embodiment, the upper edge of the locking piece 3 is in the shape of a mountain peak. Figure 1 As shown, when the locking piece 3 is located in the movable groove 5, its peak-shaped shape causes a portion of it to protrude from the movable groove 5, providing a force application point for easy unlocking.
[0021] In this embodiment, the locking plate 3 is provided with a stopper 33 to prevent excessive rotation. After the locking plate 3 has rotated a certain angle, the stopper 33 presses against the bottom of the movable slot 5, preventing further rotation of the locking plate 3 and thus affecting the reliability of the lock. Anti-sway reinforcement ribs 10 are provided on both sides of the movable slot 5 to ensure locking stability.
[0022] In this embodiment, the lock base 1 is provided with a slide groove 13 for limiting the rotation angle of the handle, and the handle 2 is provided with a limiting protrusion 12 corresponding to the slide groove 13 to prevent the handle 2 from rotating too much and being difficult to reset.
[0023] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
