Telescopic foot protection plate

Abstract

The invention aims to provide a telescopic foot protection plate which solves the shortcomings that the need for safety of shallow pits cannot be adapted and the like in the prior art. The telescopic foot protection plate comprises a fixed substrate, movable plates and a movable connecting rod, wherein the upper parts of the fixed substrate and the movable plates are provided with horizontal baserods with a horizontal guide groove; the middle part of the fixed substrate is provided with a vertical guide groove; a central hinge pin of the movable connecting rod hinged on the horizontal base rod of the movable plate reciprocates along the vertical guide groove of the fixed substrate; the fixed substrate and the movable plate or adjacent movable plates are hinged together through the horizontal guide grooves of the horizontal base rods and the end part hinge pin of the movable connecting rod, and the end part hinge pin of the movable connecting rod reciprocates along the horizontal guide grooves of the horizontal base rods; a foot protection plate lock is hinged on the horizontal base rod of the fixed substrate; and a locking pin matched with a lock hook of the foot protection platelock is fixed on the horizontal base rod of the movable plate. The telescopic foot protection plate is in a simple structure, easy to operate and safe and reliable to use.

Description

technical field [0001] The invention relates to a foot guard for elevators, in particular to a telescopic foot guard suitable for elevators in shallow pits. Background technique [0002] At present, the toe guards used by elevators are installed under the sill of the car and are not retractable. This kind of structure is simple in design and can be applied to most elevators. However, when the depth of the pit is relatively shallow, this design will scratch the floor of the pit when the elevator runs to the bottom, causing damage to the toe guards; at the same time, it may also cause injury to professional maintenance personnel in the pit, so traditional toe guards It cannot meet the safety needs of shallow pits. [0003] In the patent No. CN200520051796.X "Electric toe guard device for vertical elevator car", a design of electric toe guard is disclosed, which adopts manual control to power a small motor, and the small motor rotates, and the steering device makes the active ...
