Description

Technical Field

[0001] The utility model relates to the technical field of elevator sills, in particular to an elevator sill capable of reducing the sill gap. Background Art

[0002] An elevator sill is a metal pedal, a metal horizontal member arranged at the entrance and exit and with the opening part closely attached to the ground. The elevator sill is divided into a car sill and a landing door sill. The car sill is the sill at the car entrance, and the landing door sill is the sill at the landing door entrance.

[0003] The national elevator standard requires that the distance between the car sill and the landing door sill is 30 mm, but there is no requirement for household elevators in villas. Since the existing elevator sills are extruded profiles with unchangeable shapes, without changing the installation positions of the car sill and the landing door sill, it is impossible to adjust the gap between the car sill and the landing door sill, resulting in poor decorative effects, being not beautiful, and having a high risk of items falling into the pit. Content of the Utility Model

[0004] The purpose of the utility model is to provide an elevator sill capable of reducing the sill gap to solve the problem that it is difficult to adjust the gap between the car sill and the landing door sill.

[0006] A landing door sill;

[0007] A car sill, which comprises a first lower seat body and a first upper cover plate. The cross-section of the first lower seat body is "U"-shaped, and the first lower seat body is formed by bending a stainless steel plate. The cross-section of the first upper cover plate is "r"-shaped, and the first upper cover plate is formed by bending a stainless steel plate. A groove is formed on the first upper cover plate, and the first upper cover plate is fixedly installed on the top of the first lower seat body by welding. The side of the first upper cover plate facing the landing door sill extends out of the first lower seat body to form a first extending edge.

[0008] As a further description of the above technical scheme:

[0009] The landing door sill comprises a second lower seat body and a second upper cover plate. The second upper cover plate is fixedly installed on the second lower seat body by welding. The side of the second upper cover plate facing the car sill extends out of the second lower seat body to form a second extending edge.

[0010] As a further description of the above technical scheme:

[0011] A protruding plate is further arranged on the first extending edge, and a notch corresponding to the protruding plate in position is arranged on the second extending edge.

[0012] As a further description of the above technical scheme:

[0013] There is a waist-shaped hole on the bottom surface of the groove.

[0014] As a further description of the above technical solution:

[0015] A nut is arranged inside the first lower seat body, and the nut is fixedly welded on the first lower seat body.

[0016] As a further description of the above technical solution:

[0017] An arc-shaped bending edge is arranged at the end of the first protruding edge.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] 1. In the present utility model, the elevator sill includes a landing sill and a car sill arranged in parallel. Different from the profile sill formed by extrusion molding, the car sill includes a first lower seat body and a first upper cover plate formed by bending a stainless steel plate. The two parts of the first lower seat body and the first upper cover plate are combined together by welding.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1-3 , the present invention provides a technical solution: an elevator sill that can reduce the sill gap, including:

[0032] Landing sill 1;

[0033] Car sill 2, which includes a first lower seat body 21 and a first upper cover plate 22. The cross-section of the first lower seat body 21 is in a "U" shape, and the first lower seat body 21 is formed by bending a stainless steel plate. The cross-section of the first upper cover plate 22 is in a "J" shape, and the first upper cover plate 22 is formed by bending a stainless steel plate. A groove 221 is formed on the first upper cover plate 22, and the first upper cover plate 22 is fixedly installed on the top of the first lower seat body 21 by welding. The side of the first upper cover plate 22 facing the landing sill 1 extends out of the first lower seat body 21 to form a first protruding edge.

[0034] The landing sill includes a second lower seat body and a second upper cover plate. The second upper cover plate is fixedly installed on the second lower seat body by welding. The side of the second upper cover plate facing the car sill 2 extends out of the second lower seat body to form a second protruding edge. The structure and processing technology of the landing sill 1 are the same as those of the car sill 2.

[0035] A nut 211 is arranged inside the first lower seat body 21, and the nut 211 is fixedly installed on the first lower seat body 21 by welding. A through hole corresponding to the nut 211 in position is arranged on the first lower seat body 21. When fixing the car sill 2, the bolt passes through the bracket and the first lower seat body 21 in sequence and then is fixed to the nut 211.

[0036] Working principle: The elevator sill includes a landing sill 1 and a car sill 2 arranged in parallel. Different from the profile sill formed by extrusion molding, the car sill 2 includes a first lower seat body 21 formed by bending a stainless steel plate and a first upper cover plate 22. The two parts of the first lower seat body 21 and the first upper cover plate 22 are combined together by welding. The landing sill 1 is the same. Therefore, the car sill 2 made of stainless steel is convenient to process, and the width of the first protruding edge formed by the first upper cover plate 22 protruding from the first lower seat body 21 can be flexibly adjusted, so as to flexibly adjust the gap between the landing sill 1 and the car sill 2, reduce the gap between the two sills of the landing door and the landing door, reduce the risk of objects falling into the pit, and be more beautiful and durable.

[0037] Embodiment 2

[0038] On the basis of the above embodiment, the following improved technical solutions are further made in this embodiment: A protruding plate 222 is further provided on the first protruding edge, and a notch 11 corresponding to the protruding plate 222 in position is provided on the second protruding edge. The shape of the gap between the landing sill 1 and the car sill 2 is changed to prevent long strip-shaped objects from falling into the pit, and further reduce the risk of objects falling into the pit.

[0039] Embodiment 3

[0040] On the basis of the above embodiment, the following improved technical solutions are further made in this embodiment: A kidney-shaped hole 2211 is provided on the bottom surface of the groove 221. The groove 221 is used for guiding the movement of the car door. The setting of the kidney-shaped hole 2211 facilitates the discharge of dust and debris in the groove 221 to the cavity between the first lower seat body 21 and the first upper cover plate 22 through the kidney-shaped hole 2211, so as to avoid affecting the opening and closing of the car door.
