Description

Technical Field

[0001] This utility model relates to the field of elevator car door technology, specifically an elevator car safety door. Background Technology

[0002] As an important component of the elevator system, elevator landing doors are mainly used to separate the elevator shaft from the floor platform, ensuring passenger safety. Traditional elevator landing doors typically consist of a left door and a right door, which are opened and closed by a drive mechanism, supported by a sill and sliding along guide rails.

[0003] However, after the elevator doors are opened, the upper part of the sill is usually exposed with a concave groove structure. Over time, dust, debris and other impurities can easily accumulate in this groove, affecting the smooth operation of the door. More importantly, the heels of female passengers' high heels may accidentally get stuck in this gap, posing a serious safety hazard.

[0004] Therefore, we propose a safety door for enclosed elevators. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a car elevator safety door with a protective structure that protects the sill and improves safety, effectively solving the problems in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a safety door for a car elevator, comprising a left door, a right door, and a sill. The left door is located on the left side of the upper part of the sill, and the right door is located on the right side of the upper part of the sill. Rollers are installed at equal intervals on the middle of the lower outer surfaces of the left and right doors. A protective strip is fixedly installed on the bottom of the right outer surface of the left door. The protective strip includes a left strip, a middle strip, and a right strip. The middle strip is connected between the left and right strips by countersunk bolts. Brush protective strips are installed on both the front and rear sides of the middle of the upper outer surface of the sill. A groove is opened at the bottom of one side of the outer surface of the right door, and the groove extends to the other side of the outer surface of the right door.

[0009] Preferably, the right end of the lower outer surface of the left strip and the right end of the lower outer surface of the middle strip are both provided with upper pressing grooves, and the left end of the upper outer surface of the middle strip and the left end of the upper outer surface of the right strip are both provided with lower supporting grooves.

[0010] Preferably, when the middle strip is connected to the left strip and the right strip, the upper pressing groove is pressed into the lower supporting groove.

[0011] Preferably, the outer wall of the protective strip and the groove are slidably connected.

[0012] Preferably, the length of the protective strip is the sum of the lengths of the left and right doors.

[0013] Preferably, after the left and right doors are closed, the right end of the protective strip extends through the slide groove to the bottom of the right side of the right door.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a safety door for a cabin elevator.

[0025] like Figure 1-4As shown, the structure includes a left door 1, a right door 2, and a sill 3. The left door 1 is located on the left side of the upper part of the sill 3, and the right door 2 is located on the right side of the upper part of the sill 3. Rollers 6 are installed at equal intervals on the middle of the lower outer surfaces of the left door 1 and the right door 2. A protective strip 4 is fixedly installed on the bottom of the right outer surface of the left door 1. The protective strip 4 includes a left strip 8, a middle strip 9, and a right strip 10. The middle strip 9 is connected between the left strip 8 and the right strip 10 by countersunk bolts 13. Brush protective strips 7 are installed on both the front and rear sides of the middle of the upper outer surface of the sill 3. A groove 5 is opened at the bottom of one side of the outer surface of the right door 2, and the groove 5 extends to the other side of the outer surface of the right door 2.

[0026] The right end of the lower outer surface of the left strip 8 and the right end of the lower outer surface of the middle strip 9 are both provided with upper pressing grooves 11, and the left end of the upper outer surface of the middle strip 9 and the left end of the upper outer surface of the right strip 10 are both provided with lower supporting grooves 12. When the middle strip 9 is connected to the left strip 8 and the right strip 10, the upper pressing grooves 11 are pressed into the lower supporting grooves 12. The outer wall of the protective strip 4 is slidably connected to the sliding groove 5. The length of the protective strip 4 is the sum of the lengths of the left door 1 and the right door 2. After the left door 1 and the right door 2 are closed, the right end of the protective strip 4 extends through the sliding groove 5 to the bottom of the right side of the right door 2.

[0027] It should be noted that this utility model is a safety door for a car elevator. The left door 1, right door 2, sill 3, and roller 6 described in this document are all existing technologies and can be readily understood by those skilled in the art; therefore, they will not be described in detail here. The protective strip 4 extends into the slide groove 5. When the left door 1 and right door 2 are opened, the left door 1 drives the protective strip 4 to slide along the slide groove 5. After the left door 1 and right door 2 are opened, the protective strip 4 protects the upper end of the sill 3. It serves a protective function, and brush protective strips 7 are installed on the left and right sides of the upper part of the sill 3. When opened, the upper end of the brush protective strip 7 contacts the lower end of the protective strip 4, further enhancing the protective function. When the left door 1 and the right door 2 are closed, the left door 1 drives the protective strip 4 to move along the slide rail 5 without affecting the closing of the left door 1 and the right door 2. The protective strip 4 is composed of the left strip 8, the middle strip 9 and the right strip 10, which facilitates the individual replacement of damaged strips and reduces the cost of later maintenance.
