In the description of the present invention, it should be noted that the terms "upper", "left", "right", "vertical", "horizontal", and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, or the directions or positional relationships that the products of the present invention are conventionally placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, the present embodiment provides a car safety door, which includes a car and a safety door disposed on the car, wherein a pillar 100 is mounted on an outer side wall of the car, and a retractable pedal 200 is rotatably mounted on the pillar 100. The rotatable connection between one end of the pedal 200 and the upright 100 can be realized by means of a hinge. Through the pedal 200 that can expand, can receive and shut, the pedal 200 expandes and can provide the rescue personnel platform of standing when needing to the elevator rescue, and the pedal 200 receipts are received and can be prevented personnel from falling when the emergency exit is opened, are played the effect of baffle.

Referring to fig. 1, the pedal 200 has two opposite longitudinal sides 210 in the outward direction of the car. When the step 200 is formed in a rectangular shape, one end of the step 200 near the pillar 100 and the longitudinal side 210 are in a perpendicular relationship with each other when the step 200 is unfolded. On the longitudinal side 210 of the step 200, a foldable guardrail is provided, and specifically, the lengthwise direction of the guardrail coincides with the lengthwise direction of the longitudinal side 210. When the pedal 200 is in the folding state, the guard rails are folded to ensure that the pedal 200 can be normally folded; when footboard 200 was in the expansion state, the guardrail expanded, and guardrail, footboard 200 were mutually supported this moment, improved security and reliability on personnel's the footboard 200 of standing, especially can slow down the sense of fear of the high phobia crowd.

Further, referring to fig. 1 and 2, a locking member 300 and a plurality of steel cables 400 are disposed between the step 200 and the upright 100, the locking member 300 is used to fold, fix and separate the upright 100 and the step 200, the steel cables 400 are used to limit the stability of the spatial position of the step 200 in the unfolded state, the steel cables 400 are disposed between the step 200 and the upright 100, the steel cables 400 are configured such that the step 200 is in the tensioned state when unfolded, and the spatial position relationship among the steel cables 400, the step 200 and the upright 100 in the tensioned state is stable.

Further, referring to fig. 1 and 2, the locking member 300 can be used to achieve folding and unfolding of the pedal 200 and the shaft 100 by means of the pin 310 and the insertion hole 320. The latch 310 is provided on the shaft 100 and the receptacle 320 is provided on the pedal 200. Alternatively, the latch 310 is provided on the pedal 200 and the receptacle 320 is provided on the shaft 100.

Furthermore, the anti-slip threads are arranged on one surface of the pedal 200 facing the upright post 100, namely the anti-slip threads are arranged on the upper side surface of the pedal 200 when the pedal 200 is in the unfolding state, so that the friction coefficient between a person and the pedal 200 when the person stands on the pedal 200 is improved, and the safety is improved.

Further, referring to fig. 1, when the step 200 is in the unfolded state, the length of a portion of the wire 400 between the pillar 100 and the step 200 can be adjusted, so as to adjust the angle between the step 200 and the pillar 100 when unfolded, so that the step 200 can be more angularly arranged in the unfolded state than in the horizontal state, and can be more suitable for the operation in practical situations. For example, the pedals 200 may be in a horizontal state when deployed, may be distributed slightly obliquely upward, or may be distributed slightly obliquely downward. In the actual elevator fault situation, because the position of the faulted elevator is uncertain, when the faulted elevator is assisted by the adjacent elevator, the adjacent elevator is difficult to move to the position which is at the same level with the faulted elevator, and the butt joint between the faulted elevator and the adjacent elevator is simpler through the fine adjustment of the inclination of the pedal 200 in the unfolding state, so that the personnel in the faulted elevator can be assisted more quickly. And the pedal 200 is inclined slightly upwards, so that the friction force applied to a person standing on the pedal 200 is larger, and the person can feel more safety.

Further, referring to fig. 1 and 2, the length of the wire rope 400 between the pedal 200 and the upright 100 is adjusted by arranging the hanging ring 220 and the winch 230 on the pedal 200. Specifically, the pedal 200 is hinged to the upright 100, a hanging ring 220 is disposed at one end of the pedal 200 away from the hinged point, a winch 230 is disposed on the pedal 200, one end of the wire rope 400 is fixedly disposed on the upright 100, and the other end of the wire rope 400 passes through the hanging ring 220 and is wound on the winch 230. The length of the portion of the wire rope 400 between the step 200 and the shaft 100 is adjusted so that the step 200 is horizontally placed or obliquely placed in the unfolded state.

The capstan 230 may be configured with a motor, and the capstan 230 may be rotated by the motor to adjust the wire rope 400. The motor is controlled by the controller accordingly, so that the purpose of automatically adjusting the length of the part of the steel wire rope 400 between the pedal 200 and the upright 100 is achieved.

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.
