Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 2 to 7, a sill anti-disengaging structure of an elevator door includes two door panels 1 and a sill 2, wherein the bottom of the door panel 1 is inserted into the sill 2, the door panel 1 is connected to a slide rail 3 located above the door panel 1 through a slide block 4, and the upper end of the door panel 1 is connected to a driving mechanism and pushes the door panel 1 to slide left and right.

As shown in fig. 2 and 5, the sill 2 is a hollow structure and has an opening at the top, the opening is only the middle part of the top surface of the sill, the top of the sill 2 is provided with a second groove 22 along the sliding direction of the door panel 1, the second groove 22 is the opening of the sill 2, the second groove 22 penetrates through the whole sill 2 in the length direction of the sill 2, and the second groove 22 is communicated with the hollow part inside the sill 2 in the height direction of the sill 2.

As shown in fig. 2 and 7, the door panel 1 includes a main board 11 and a folded plate 15 located at the bottom of the main board 11, the main board 11 and the folded plate 15 are both thin plates, the folded plate 15 and the main board 11 are integrally formed by bending, the folded plate 15 is distributed along a strip shape formed by bending the bottom of the main board 11, the length N of the folded plate 15 is smaller than the length L of the main board 11, the folded plate 15 passes through a second groove 22 and extends into the sill 2, a folded edge 23 is arranged at one side of the second groove 22 far from the main board 11, the inner side of the sill 2 is bent downwards through the folded edge 23 to form a concave portion 24, the tail of the folded plate 15 is located in the concave portion 24, and the folded plate 15 and the concave portion 24 of the sill 2 form a non-connection fixing buckle structure.

Specifically, as shown in fig. 3, the flap 15 includes a bottom plate 12 and a first flap 13 bent downward at 90 degrees from the bottom plate 12, the bottom plate 12 extends vertically along the bottom of the main plate 11 and is parallel to the top surface of the sill 2, the first flap 13 extends vertically downward along the side of the bottom plate 12 away from the main plate 11, and the first flap 13 passes through the second groove 22 and extends into the sill 2.

As shown in fig. 3, the folding plate 15 further includes a second folding plate 14 located at the bottom of the first folding plate 13 and bent to one side of the folding edge 23 at an angle of 90 degrees with the first folding plate 13, the second folding plate 14 extends vertically along the bottom of the first folding plate 13 away from one side of the main plate 11, or the second folding plate 14 extends out of the folding edge 23 along the direction close to the folding edge 23, the second folding plate 14 includes a third folding plate 141 bent upward along the tail of the second folding plate 14, the third folding plate 141 is at least partially located in the concave portion 24, because the door panel 1 is fixed and driven to slide at the upper end, the third folding plate 141 only needs to be located in the concave portion 24 without contacting with the inner wall of the concave portion 24, when the door panel 1 is greatly deformed due to severe impact, the sill 2 can hook the folding plate 15 depending on the structural and positional relationship between the third folding plate 141 and the concave portion 24, so as to prevent the bottom of the door panel 1 from being separated from the sill 2 accidentally.

As shown in fig. 2 and 5, the middle section of the second groove 22 is widened to form a first groove 21 away from the main board 11, the folded edge 23 is completely cut off within the length range of the first groove 21, a larger notch is formed on the top surface of the sill 2 within the length range of the first groove 21, and the first groove 21 is symmetrically distributed along the joint line when the two door panels 1 are closed, that is, the first groove 21 is symmetrically distributed along the center line of the sill 2.

As shown in fig. 3, 4, 5 and 6, the width Q of the first groove 21 is greater than the width P of the second folding plate 14 in the horizontal direction, as shown in fig. 2 and 7, the length M of the first groove 21 is greater than the length N of the second folding plate 15, when the door panel 1 is installed, the door panel 1 is placed in the first groove 21 and pushed out to one side, after the upper end of the door panel 1 is connected, the door panel 1 is completely pushed through the first groove 21 along one side, then the other door panel 1 is inserted into the first groove 21 for installation, and when the door panels 1 on two sides are installed, the hook part folding plate three 141 of the second folding plate 14 and the concave part 24 of the sill 2 form a buckling structure while the sill 2 slides along the second groove 22.

As shown in fig. 2, after the door panel 1 is completely opened, the inner sides of the folding plates 15 are located in the second grooves 22, that is, the folding plates 15 on the inner sides of the two door panels 1 slide out of the left and right ends of the second grooves 22.

As shown in fig. 2, when the two side panels 1 are closed, the length of the flap 15 in the slot two 22 exceeds half of the length of the flap 15, i.e. the length of the flap 15 in the slot two 22 is greater than the length of the flap 15 in the slot one 21.

The folded plate 15 through the door plant 1 bottom forms the fixed buckle structure of non-connection with concave part 24 of sill 2, relies on this structure to prevent that the door plant 1 bottom from breaking away from sill 2, compares in the structure among the background art, has saved the structure of baffle, has avoided producing not hard up because of the baffle junction receives door plant 1 bottom deformation, and leads to the potential safety hazard that the baffle breaks away from sill 2 and brings.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
