Detailed Description

In order to clearly understand the technical solution of the present invention, the present invention is further illustrated by the following embodiments in combination with the accompanying drawings.

Example 1:

the combined sill provided by the embodiment comprises a sill body 1 and a sill support 2, as shown in fig. 1, a sliding groove 3 is formed in the middle of the sill body 1 in a concave manner, a short horizontal platform 4 is connected to one side of the upper end of the sliding groove 3, a long horizontal platform 5 is connected to the other side of the upper end of the sliding groove 3, an anti-falling groove 6 is formed in the side of the sliding groove 3 in a concave manner, a boss 7 protruding from top to bottom is arranged between the sliding groove 3 and the anti-falling groove 6, the boss 7 and the outer side of the anti-falling groove 6 form a barb shape, a T-shaped cavity 9 for accommodating a connecting fastener 8 is further arranged on the sill body 1, the sill support 2 is arranged below the sill body 1, as shown in fig. 3, the sill support 2 comprises a transverse plate 10 and two side plates 11, two sides of the transverse plate 10 are respectively connected with the lower ends of the two side plates 11 to form a groove 12, inwardly bent support arms 13 are arranged on the groove 12, the upper surfaces, the transverse plate 10 is arranged below the chute 3 and the T-shaped cavity 9 and is in surface contact with the chute 3, and a first notch 14 is arranged on the transverse plate 10 at a position corresponding to the opening of the T-shaped cavity 9.

In the actual installation use, in this embodiment fastener 8 can adopt the bolt, the bolt head of this bolt is placed in the T die cavity 9 of sill body 1, the bolt passes first breach 14 on sill support 2, it fixes sill body 1 and sill support 2 as an organic whole to twist the nut, when the elevator suffers external force and strikes door slider 2 rebound, sill body 1 can catch on each other with the door slider of taking the barb, form interlocking structure, thereby guarantee when the elevator suffers external force and assaults, the door slider can not deviate from spout 3, diaphragm 10 and the both sides support arm 13 of sill support 2 all with 1 face contact of sill body, good and the processing of supporting effect is convenient.
