Description

Guiding elevator landing door unlocking device

Technical Field

The utility model relates to an elevator layer door lock field, in particular to direction formula elevator layer door unlocking device.

Background

The running quality of the elevator is ensured, and the elevator floor door lock is used as a projection. The emergency unlocking of the common door lock is realized by inserting a triangular key into a lock hole outside a hall door and rotating an ejector rod to jack up the door lock to unlock the door lock, and the operation has certain difficulty and risk due to the limitation of the shape and height position of the key. The difficulty and risk are particularly evident when the landing door height increases. This is where the application needs to be focused on.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a direction formula elevator layer door unlocking means that operating risk is low will be provided.

In order to solve the technical problem above, the utility model provides a direction formula elevator layer door unlocking means, the lower part of a locking lever passes in the hole of locking lever holder and guide holder down fixed, locking lever upper portion overcoat has pressure spring and a fixed pressure spring stopper, locking lever top and cam carrier rigid coupling, a driving lever passes through the clutch collar and fixes on the locking lever, the driving lever is connected with the rotating part, the rotating part dress is in the layer door hole, the key inserts layer door hole and rotates the rotating part and drive the driving lever, it backs down the trip to drive the locking lever upwards to slide, open the layer door lock.

And a locking rod stroke limiting block is fixedly connected to the lower part of the locking rod close to the lower guide seat to prevent the locking rod from exceeding the stroke.

The lock rod is connected with a handle, and the handle is pulled to unlock in a manual mode.

The lock rod retainer is connected with the bottom plate, the base is fixed on the cam frame, the bottom plate and the base are connected with the layer door plate, and the cam is fixed on the cam frame.

The lower guide seat is fixed on the layer door plate.

The utility model has the advantages that: the required unlocking force is small, an operator does not need to move the gravity center of the body, and the risk and the difficulty of operation are greatly reduced.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of an embodiment of the present invention. As shown in fig. 1-3, the utility model provides a direction formula elevator layer door unlocking device, lower guide holder 1 is fixed and is provided the direction for the locking lever motion on layer door plant 12, and layer door plant 12 still is connected with bottom plate 3 and base 13, and base 13 is fixed on cam rack 9, is fixed with cam 14 on the cam rack 9, and bottom plate 3 is connected with locking lever holder 5. The lower part of the lock rod 6 passes through the lock rod holder 5 and the hole of the lower guide seat 1 to be fixed, and the lock rod holder 5 enables the lock rod 6 to be kept vertical in the operation process. The outer cover in 6 upper portions of locking lever has pressure spring 7 and a fixed pressure spring stopper 8, and 6 tops of locking lever are connected with the internal thread hole of cam rack 9, and driving lever 10 passes through the metal clamping sleeve and presss from both sides tightly on locking lever 6, and driving lever 10 is connected with rotating piece 11, and rotating piece 11 adorns in the layer door hole, and the key inserts layer door hole and rotates rotating piece 11 and drive driving lever 10, drives locking lever 6 and upwards slides and backs down the trip, opens the layer door lock.

And a locking rod stroke limiting block 2 is fixedly connected to the lower part of the locking rod 6 close to the lower guide seat 1 to prevent the locking rod 6 from exceeding the stroke.

The locking rod 6 is connected with the rubber handle 4 through a taper pin, the rubber handle 4 is pulled to drive the locking rod 6 to slide upwards to jack the lock hook, and the layer door lock is opened.

The curved surface of the door lock hook cam of the elevator landing door is contacted with the cam 14 at the upper end of the cam rack 9 in the motion process in the closing process, the lock rod 6 is pressed to move downwards, so that the lock rod 6 is brought to the locking position below the door lock hook, and the landing door lock is in a locking state at the moment. The locking lever 6 is now inactive. When emergency operation is carried out outside the landing door, the triangular key is inserted into the landing door hole to rotate the rotating piece 11 to drive the shifting rod 10, so that the locking rod 6 moves upwards to jack the locking hook, and the door lock is opened. Because the locking rod 6 is guided by the lower guide seat 1 and runs under the protection of the locking rod retainer 5, the running verticality of the locking rod 6 is ensured. After the layer door is opened, the lock rod 6 automatically resets under the action of the elasticity of the pressure spring 7, and the elasticity of the pressure spring 7 is provided by a stroke limiting block 8 fixed on the lock rod 6 by a screw.

When the lock needs to be unlocked in the hoistway, the rubber handle 4 is pulled by hand to drive the lock rod 6 to move upwards to jack the lock hook, so that the door lock is opened.

In the two unlocking modes, the descending stroke of the locking rod 6 is limited by the locking rod stroke limiting block 2, and the ascending stroke of the locking rod 6 is limited by the contact of the deflector rod 10 and the rotating piece 11.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
