Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an anti-slip structure for a safety lock piece. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. The elevator machine room power box is a device for placing the elevator power distribution equipment. The elevator machine room power box has a simple locking device. When the existing locking device is in use, the lock tongue will slip due to the influence of gravity, causing the opened lock to close again, affecting people's use. Utility Model Content

[0003] The utility model provides a safety lock piece anti-slip structure, aiming to solve the problem that when the existing locking device is in use, the lock tongue will slide due to the influence of gravity, so that the opened lock house will be closed again, affecting the use of people.

[0004] The utility model is implemented as follows: a safety lock plate anti-slip structure comprises a lock shell, the outer wall of the lock shell is fixedly connected to a door panel, and the outer wall of the door panel is hinged to a box body, a lock core is arranged inside the lock shell, and the outer wall of the lock core is fixedly connected to a lock tongue, the inner wall of the box body is fixedly connected to a lock plate matching the lock tongue, and the outer wall of the lock core is slidably connected to a limiting block, a limiting block is provided inside the lock core, and one end of a spring is fixedly connected to the inner wall of the equipment cavity, the other end of the spring is fixedly connected to the limiting block, the outer wall of the lock core is fixedly connected to one end of a connecting rope, and the other end of the connecting rope passes through the spring and is fixedly connected to the limiting block.

[0005] Preferably, a groove wheel is fixedly connected to the inner wall of the equipment cavity.

[0006] Preferably, a heat dissipation opening is provided on the outer wall of the box.

[0007] Preferably, a dustproof net is fixedly connected to the inner wall of the heat dissipation port.

[0008] Preferably, the outer wall of the door panel is provided with glass.

[0009] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0010] When a person inserts a key into the lock core and presses the key, the lock core is displaced in the lock shell. The displacement of the lock core causes the protruding limit block to retract through the connecting rope, preventing the protruding limit block from hindering the rotation of the lock tongue. The person rotates the lock core, causing the lock core to drive the lock tongue to disengage from the lock plate, thereby opening the lock. After the lock is opened, the person releases the pressure on the key, and the spring force is restored to restore the position, causing the limit block to protrude, thereby limiting the position of the lock tongue and preventing the lock tongue from slipping.
