Referring to fig. 1 to 4, an elevator landing sill comprises a sill body 1 having a shoe guide groove 101, a sill bracket 2 having a U-shaped structure, and a sill lining 3 disposed between the sill body 1 and the sill bracket 2, wherein the sill body 1 is made of aluminum alloy, the sill lining 3 and the sill bracket 2 are made of ordinary steel by bending, the sill body 1, the sill bracket 2 and the sill lining 3 are fixedly connected by a bolt 4, specifically, a C-shaped groove 102 is disposed on one side of the shoe guide groove 101, the bolt 4 is disposed in the C-shaped groove 102, holes (not shown) corresponding to the openings of the C-shaped groove 102 are disposed on the sill lining 3 and the sill bracket 2, the bolt 4 sequentially passes through the holes on the sill lining 3 and the sill bracket 2 and then is fastened by a locking nut 5, it is worth describing that the locking nut 5 is used to fasten the bolt 4 in this embodiment, compared with the prior art that the bolt 4 is fastened by adopting a common nut, the bolt 4 can be better prevented from loosening, and the reliability of nut locking is ensured.

Meanwhile, two ends of the sill body 1 are respectively provided with a U-shaped placing groove 103, the openings of the two placing grooves 103 are oppositely arranged, and in the embodiment, the openings of the two placing grooves 103 face the guide shoe groove 101;

in addition, horizontal supporting sections 301 are arranged at two ends of the sill lining plate 3, horizontal extending parts 201 are arranged at two ends of the sill bracket 2, the bottom surfaces of the horizontal extending parts 201 are attached to the inner bottom surface of the placing groove 103, and the bottom surfaces of the horizontal supporting sections 301 are attached to the top surfaces of the horizontal extending parts 201; the end surface of the horizontal extension part 201 and the end surface of the horizontal support section 301 are attached to the inner side surface of the placement groove 103; in an embodiment, the top surface of the horizontal supporting section 301 is also attached to the bottom surface of the sill body 1, so as to further enhance the strength of the door sill.

Through the above-mentioned setting, on the basis of simplifying the bearing structure of sill body 1, through the tip at sill body 1 sets up mounting groove 103, overlap the horizontal extension 201 of the horizontal support section 301 of sill welt 3 and sill bracket 2 simultaneously and set up in mounting groove 103, and horizontal support section 301, horizontal extension 201 and mounting groove 103 three laminate each other, when making the sill of the landing door receive the side direction striking, rely on horizontal support section 301 and horizontal extension 201 not only can eliminate the ascending power of horizontal direction, and the ascending power in vertical direction is used in horizontal support section 301 and horizontal extension 201 back, owing to there is the bottom bearing of mounting groove 103, in order to prevent that sill bracket 2 warp, thereby realize further strengthening this sill of landing door's intensity.

In the embodiment, considering that the guide shoe groove 101 and the sliding block 6 matched with the guide shoe groove are both rectangular structures, when the landing door sill is normally used, two sliding blocks 6 are usually installed on each landing door, when the landing door sill is opened and closed, the sliding block 6 slides left and right in the rectangular guide shoe groove 101, and the sliding block 6 plays a role in guiding and limiting; when the landing door is elastically deformed by impact, the landing door is bent, the sliding block 6 is lifted up, if the deformation is too large, and the upward lifting distance exceeds the engagement depth of the sliding block 6 and the guide shoe groove 101, the landing door can be separated from the guide shoe groove 101 and ejected towards the well way, and accidents are easily caused. In order to solve the problem, a sliding block 6 and a connecting piece 7 are arranged inside the guide shoe groove 101, and the elevator floor door is connected with the sliding block 6 through the connecting piece 7; wherein, the inside bilateral symmetry of leading boots groove 101 is equipped with spacing strip 8, and two spacing strips 8 are located the top of slider 6, and the interval between two spacing strips 8 is less than the interval on slider 6 both sides limit. In one embodiment, referring to the inside of fig. 1, the two position-limiting strips 8 are fixed in the shoe guide groove 101 through bolt assemblies, so as to be convenient for disassembly and assembly; meanwhile, the bottom surfaces of the two limiting strips 8 are inclined surfaces, and one side of the two limiting strips, which is close to the side wall of the guide shoe groove 101, is higher, and the area, corresponding to the bottom surfaces of the limiting strips 8, of the top surface of the sliding block 6 is also arranged as an inclined surface, and the other side of the top surface of the sliding block, which is close to the side wall of the guide shoe groove 101, is higher; and the top surface of the limit strip 8 and the top surface of the sill body 1 are positioned on the same horizontal plane, so that the landing sill is more attractive, the structure is more compact, and the strength is higher. When the landing door receives the impact, because the limiting action of the limiting strip 8 can make the slide block 6 be located in the space between the bottom surface of the limiting strip 8 and the bottom in the guide shoe groove 101 all the time, the landing door is prevented from being separated from the sill body 1, and accidents are caused. In addition, in order to reduce the impact of the sliding block 6 and the connecting piece 7 on the limiting strip 8 when the landing door deforms, the limiting strip 8 is made of elastic buffer materials, so that the limiting strip 8 has a certain buffering effect.

In this embodiment, in the practical use process, water still exists and spills on the landing sill, which causes that water flows into the guide shoe groove 101 and is not discharged well, if water is accumulated in the guide shoe groove 101 for a long time, the guide shoe groove 101 or the inside of the sliding block 6 is easily rusted, which affects the normal sliding of the sliding block 6 and reduces the service life of the landing sill body 1. In order to solve the problem, a plurality of flow guide channels are arranged at the inner bottom of the guide shoe groove 101, and the flow guide channels sequentially penetrate through the sill body 1, the sill lining plate 3 and the sill bracket 2 along the vertical direction. When water flows into the guide shoe groove 101, the water can be discharged in time through the guide passage. Specifically, the sill lining plate 3 is further provided with a bottom supporting section 302 and a vertical supporting section 303, two sides of the bottom supporting section 302 are respectively connected with the horizontal supporting sections 301 at two ends through the vertical supporting section 303, the top surface of the bottom supporting section 302 is attached to the bottom surface of the sill body 1, and the bottom surface of the bottom supporting section 302 is attached to the inner top surface of the sill bracket 2; in addition, in the embodiment, the side surface of one of the vertical support sections 303 is attached to one side surface of the guide shoe groove 101, and the side surface of the other vertical support section 303 is attached to the side surface of the C-shaped groove 102; through the arrangement, the structural strength of the landing sill is further improved, and meanwhile, the landing sill is more compact in structure and more reasonable in design. Meanwhile, the flow guide channel comprises a flow guide hole I104 arranged at the bottom in the flow guide shoe groove 101, a flow guide hole II304 arranged on the bottom support section 302, and a flow guide hole III202 arranged on the sill bracket 2, wherein the flow guide hole I104, the flow guide hole II304 and the flow guide hole III202 are sequentially communicated, so that the flow guide channel for water to flow through is formed. In specific implementation, in order to make the flow through the diversion channel more uniform, the inner diameters of the diversion holes I104, II304, and III202 are the same and the three are concentrically arranged.

In the present embodiment, in order to enhance the anti-slip performance of the sill body 1. The top surface of foretell sill body 1 is equipped with a plurality of antiskid groove 105, the setting of a plurality of antiskid groove 105 interval and equidistant.
