Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator landing door guiding and anti - detachment device. Background Technique

[0002] At present, elevators are becoming increasingly closely related to our lives and can be seen everywhere in residential buildings, hotels, shopping malls, etc. They are essential equipment for modern development. An elevator is not only a means of transportation, but also how to make the elevator landing door run safely and anti - detachably and smoothly is crucial, especially for integrally bent and formed landing door panels. The common elevator car landing door structures currently are composed of a door panel main body, upper and lower end caps, and reinforcing ribs, with complex structure processes and numerous procedures. For the currently integrally bent and formed landing door panel, due to its special structure, it is impossible to install ordinary door guide shoes. When the door panel runs between the sill chutes, a guiding device needs to be added. Also, because the national standard requires that when the landing door is in the locked position and the car door is in the closed position, all landing doors, their door locks, and the car door should meet certain mechanical strengths, a retaining anti - detachment device needs to be added. Otherwise, there is a risk of damaging the passengers or transported items during the use of the elevator car, and the use safety of the elevator car cannot be guaranteed. Summary of the Invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides an elevator landing door guiding and anti - detachment device, which plays a guiding role during the opening and closing operation of the elevator landing door and a safety anti - detachment role when the landing door is impacted.

[0004] To achieve the above - mentioned purpose, the utility model adopts the following technical solutions:

[0005] An elevator landing door guiding and anti - detachment device includes an elevator landing door panel main body, a landing door guiding and anti - detachment device, and an elevator sill assembly. The landing door guiding and anti - detachment device is installed at the bottom of the elevator landing door panel main body, and the elevator sill assembly cooperates with the elevator landing door panel main body for operation.

[0006] The landing door guiding and anti - detachment device is connected to the elevator landing door panel main body by bolts.

[0007] The landing door guiding and anti - detachment device includes a guide shoe metal plate and rubber sliders. The rubber sliders are symmetrically embedded at both ends on the guide shoe metal plate.

[0008] The guide shoe metal plate is integrally stamped into a shape, and the stamped bending surfaces are perpendicular to each other to form a first vertical bending surface, a horizontal bending surface, and a second vertical bending surface that are sequentially connected.

[0009] On the first vertical bending surface, waist - shaped holes are symmetrically opened at both ends along the length direction. The first vertical bending surface is connected to the elevator landing door panel main body by bolts passing through the waist - shaped holes.

[0010] Four equally spaced convex ribs are formed by stamping on the second vertical bending surface. Shaped holes are stamped between the first and second convex ribs and between the third and fourth convex ribs. The shaped holes extend towards the horizontal bending surface to form a "convex"-shaped through hole. Rubber sliders are installed in the part of the shaped holes within the second vertical bending surface.

[0011] On both sides of the said shaped hole, there are limiting stop edges left at the transition connection between the second vertical bending surface and the horizontal bending surface within the second vertical bending surface.

[0012] An indentation for showing the meshing depth between the elevator landing door panel and the elevator sill is stamped in the upper middle part of the second vertical bending surface.

[0013] The beneficial effects of the present utility model are as follows: By adding a corresponding guiding and anti-disengagement device to the elevator landing door, the present utility model can play a role in protecting the elevator landing door from disengagement. It plays a guiding role during the opening and closing operation of the elevator landing door, and plays a role in safety anti-disengagement when the landing door is impacted, reducing the risk of damage to passengers or transported items during the use of the elevator car, and improving the use safety of the elevator car.

[0018] The following will be described in detail with reference to the embodiments of the present utility model with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0020] As Figures 1 - 3 shown, a kind of elevator landing door guiding and anti-disengagement device includes a main body 1 of the elevator landing door panel, a landing door guiding and anti-disengagement device 2, and an elevator sill assembly 3. The landing door guiding and anti-disengagement device 2 is installed at the bottom of the main body 1 of the elevator landing door panel, and the elevator sill assembly 3 operates in cooperation with the main body 1 of the elevator landing door panel.

[0021] The described landing door guiding and anti - detachment device 2 is bolt - connected to the main body 1 of the elevator landing door panel, playing a role in guiding and preventing detachment of the main body 1 of the elevator landing door panel.

[0022] The described landing door guiding and anti - detachment device 2 includes a guide shoe metal plate 21 and rubber sliders 22. The two ends of the rubber sliders 22 are symmetrically embedded on the guide shoe metal plate 21, and the rubber sliders 22 play a guiding role.

[0023] The described guide shoe metal plate 21 is integrally stamped into a shape. The stamped bending surfaces are perpendicular to each other to form a first vertical bending surface 211, a horizontal bending surface 212, and a second vertical bending surface 213 that are connected in sequence.

[0024] On the first vertical bending surface 211, waist - shaped holes 2111 are symmetrically opened at both ends along the length direction. The first vertical bending surface 211 is connected to the main body 1 of the elevator landing door panel by bolts passing through the waist - shaped holes 2111.

[0025] Four equally - spaced convex ribs 2131 are formed by stamping on the second vertical bending surface 213. Special - shaped holes 2132 are stamped between the first and the second convex ribs 2131 and between the third and the fourth convex ribs 2131. The special - shaped holes 2132 extend towards the horizontal bending surface 212 to form a "convex" - shaped through - hole. Rubber sliders 22 are installed in the part of the special - shaped holes 2132 on the second vertical bending surface 213. The convex ribs 2131 increase the strength of the structure of the guide shoe metal plate 21 and reduce the risk of the elevator landing door panel detaching from the sill.

[0026] On both sides of the described special - shaped hole 2132, limiting stop edges 2133 are left at the transition connection between the second vertical bending surface 213 and the horizontal bending surface 212 inside the second vertical bending surface 213. The limiting stop edges 2133 limit the position of the rubber sliders 22.

[0027] An indentation 2134 for showing the meshing depth between the elevator landing door panel and the elevator sill is stamped in the upper middle part of the second vertical bending surface 213 to meet the requirements of the new elevator inspection regulations.

[0028] During application, the landing door guiding and anti - detachment device 2 is installed at the bottom of the main body 1 of the elevator landing door panel. The elevator sill assembly 3 operates in cooperation with the main body 1 of the elevator landing door panel. The landing door guiding and anti - detachment device 2 is bolt - connected to the main body 1 of the elevator landing door panel, playing a role in guiding and preventing detachment of the main body 1 of the elevator landing door panel, playing a guiding role during the opening and closing operation of the elevator landing door, and playing a role in safety anti - detachment when hitting the landing door.
