Description

Technical Field

[0001] This utility model relates to the field of elevator car sill technology, specifically a spliced ​​car sill. Background Technology

[0002] The main body of the car sill is usually a long strip of metal pedal or aluminum alloy, with a groove in the middle for the car door to slide. The width of the groove is generally designed according to the door operator system and the size of the door. Car sills are divided into center-parted sills, center-parted double-folding sills and side-opening double-folding sills.

[0003] In the existing technology, the groove width of the center-split sill is 12mm and the overall width is 60mm. The groove width of the center-split double-fold sill and the side-opening double-fold sill is 12mm and the overall width is 96mm. Since the types of sills are different, their specifications are also different. This results in a large variety of component materials during the assembly of the sill. The corresponding sill must be selected according to the type of elevator, which leads to the need to prepare sills of multiple specifications, resulting in high material costs for sill components.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A modular car sill includes a first material 1 and a second material 2. A first contact edge 3 is integrally formed on a vertical surface of one side of the first material 1, and a second contact edge 4 is integrally formed on a vertical surface of one side of the second material 2. The top surface of the first contact edge 3 and the bottom surface of the second contact edge 4 are in contact with each other. The side surface of the first contact edge 3 abuts against the side surface of the second material 2, and the side surface of the second contact edge 4 abuts against the side surface of the first material 1.

[0023] Please see Figure 1 and Figure 3 The top surface of the first contact edge 3 and the bottom surface of the second contact edge 4 are attached to each other by plane to form a vertical overlapping structure. At the same time, the side of the first contact edge 3 abuts against the side of the second material 2, and the side of the second contact edge 4 abuts against the side of the first material 1, forming a double limiting. When the first material 1 is used alone, the groove on the top of the first material 1 can be used as a slide for a center-parting door. When the first material 1 and the second material 2 are spliced ​​together, the two grooves on the top can be used as slides for a center-parting double-folding door and a side-opening double-folding door, realizing the rapid adaptation of different specifications of thresholds and greatly reducing the types of materials and inventory costs.

[0024] Multiple guide posts 5 are fixedly connected horizontally and at equal intervals on the side of the second contact edge 4. Multiple countersunk holes 6 with the same diameter as the guide posts 5 are provided on the vertical surface of the first material 1 side. One end of the guide post 5 is inserted into the inside of the countersunk hole 6.

[0025] Please see Figure 2 and Figure 4 During splicing, the guide post 5 is inserted into the countersunk hole 6 to achieve lateral positioning. The gap between the guide post 55 and the countersunk hole 6 is controlled within 0.1mm to ensure no shaking after splicing. The surface of the guide post 5 can be plated with hard chrome or coated with polytetrafluoroethylene to reduce the coefficient of sliding friction with the countersunk hole 6.

[0026] The first material 1 has a first cavity 7 on its side, and the second material 2 has a second cavity 8 on its side. The inner wall of the first cavity 7 has a first protrusion 9 integrally formed, and the inner wall of the second cavity 8 has a second protrusion 10 integrally formed. A first groove 11 is formed between the first protrusion 9 and the second protrusion 10. A second groove 12 with the same width as the first groove 11 is provided below the second material 2.

[0027] Please see Figures 1-4 When the first material 1 is used alone, the first slide 11 can be directly fixed to the sill support. When the first material 1 and the second material 2 are used in combination, the first slide 11 and the second slide 12 are fixed to the sill support at the same time, so that the fixing method of the sill and the sill support is more uniform in the two usage scenarios. In the conventional case, one row of double-fold and side-opening double-fold doors is fixed by the slide 11, and the other row is fixed by the connecting hole. In the improved case, the doors are fixed by the first slide 11 and the second slide 12 with the same width, which correspond to different door opening widths.

[0028] An auxiliary connecting assembly is provided between the first cavity 7 and the second cavity 8. The auxiliary connecting assembly includes a connecting part 13 and a connecting plate 14. The four connecting parts 13 are divided into two groups and are horizontally fixed to the inner walls of the first cavity 7 and the second cavity 8, respectively. The two ends of the connecting plate 14 are connected to the two groups of connecting parts 13 through a connecting structure. The connecting structure includes a receiving groove 15 and a T-shaped limiting part 16. The receiving groove 15 is disposed between the two vertical connecting parts 13. The T-shaped limiting part 16 is integrally formed on both sides of the connecting plate 14. The T-shaped limiting part 16 is slidably connected to the inside of the receiving groove 15. The two T-shaped limiting parts 16 abut against the inner walls of the first cavity 7 and the second cavity 8, respectively.

[0029] Please see Figures 1-4 During installation, align the T-shaped limiting parts 16 at both ends of the connecting plate 14 with the receiving groove 15 (the receiving groove 15 is formed by the gap between the two sets of connecting parts 13). After horizontally pushing it in, the top and bottom surfaces of the T-shaped limiting parts 16 abut against the inner walls of the first cavity 7 and the second cavity 8 respectively, forming a self-locking mechanism to suppress lateral displacement caused by the vibration of the door machine at the splice. The first material 1 and the second material 2 can be separated by horizontally pulling out the connecting plate 1414 without damaging the structure. The connecting plate 14, as a rigid cross-connector, connects the first material 1 and the second material 2 into one, improving the overall bending stiffness. The sliding fit between the T-shaped limiting parts 16 and the receiving groove 15 allows for quick insertion and removal without the need for threaded fasteners. Rubber sealing strips are added to the contact surfaces of the T-shaped limiting parts 16 and the receiving groove 15 to prevent dust from entering the cavity. Nylon wear-resistant bushings are embedded in the first slide groove 11 and the second slide groove 12 to extend the service life.

[0030] Structural principle: Using the first material 1 alone, the groove on its top directly serves as the center-parting door slide. The second material 2 is inserted into the countersunk hole 6 of the first material 1 through the guide post 5, so that the first contact edge 3 and the second contact edge 4 are in contact with each other through the plane. At the same time, the side of the first contact edge 3 abuts against the side of the second material 2, and the side of the second contact edge 4 abuts against the side of the first material 1. Then, the connecting plate 14 is inserted, so that the T-shaped limiting part 16 cooperates with the receiving groove 15. At this time, the first material 1 and the second material 2 can be connected into a whole. The two parallel grooves on the top can directly serve as the center-parting double-folding door slide or the side-opening double-folding door slide.

[0031] Overall, the splicing design of the first material 1 and the second material 2 enables rapid adaptation of sills of different specifications, significantly reducing the types of materials and inventory costs. The insertion and matching of the guide post 5 and the countersunk hole 6 ensures accurate splicing alignment, eliminates manual adjustment errors, improves assembly efficiency, and has strong versatility. The T-shaped limiting part 16 of the auxiliary connecting component works in concert with the connecting plate 14 to significantly improve the shear resistance of the splicing node. The connecting plate 14 is fixed by the sliding T-shaped limiting part 16 and can be disassembled without special tools, which facilitates later maintenance or replacement of parts.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
