Description

Technical Field

[0001] This utility model relates to the field of door sealing and light-blocking technology, and in particular to an elevator door seam sealing strip. Background Technology

[0002] The elevator and escalator market is currently experiencing increasingly fierce competition, with products constantly being updated. Major elevator companies are simplifying and optimizing their processes while maintaining quality, continuously replacing and improving the sealing strips used in elevators. Functionally, elevator sealing strips serve to prevent impacts, provide sealing, block light, and add aesthetic appeal.

[0003] In existing technologies, rubber strips are generally used on the sides of landing doors, requiring a configuration for each floor, resulting in high costs. The strip body is made by extruding two types of rubber and a metal strip together. The rubber strip in contact with the door panel is harder, while the rubber at the final contact point is softer. The metal strip is roll-formed to increase rigidity, but this process is costly. The two strips are fixed to the door panel with rivets. The front ends of the strips are rounded to fit snugly against the door panel's bend radius. When the door is closed, the interlocking convex and concave structures of the strips provide light shielding and reduce noise from the impact at the closing end. However, the existing structure of the rubber strip is unsuitable for use on the car door side and cannot be used in conjunction with light curtains.

[0004] Therefore, an elevator door gap sealing strip is provided to address the shortcomings of existing technologies. Utility Model Content

The light-shielding portion 12 and the connecting portion 11 are bonded using a snap-fit ​​structure and pre-pressed adhesive, which will prevent the light-shielding portion 12 from loosening. The connecting portion 11 is made of a rigid material, such as PVC modified plastic; the light-shielding portion 12 is made of a flexible material, such as rubber. By reducing the three materials to two, the structure and process are simplified, eliminating the need for an embedded metal strip, resulting in lower costs and wider applicability.

[0037] In one embodiment, the light-shielding portion 12 includes a first sealing head 121 and a second sealing head 122. The first sealing head 121 has a convex surface, and the second sealing head 122 has a concave surface adapted to the convex surface. Preferably, referring to... Figures 7-8 As shown, the contact point between the first sealing head 121 and the second sealing head 122 can also be toothed or cross-shaped.

[0038] In one embodiment, the door seam sealing strip further includes a first connector 4 and a second connector 5. To avoid interference between the light curtain 3 and the first connector 4, the connecting part 11 is provided with a plurality of first mounting holes 111 and second mounting holes 112 arranged in a double layer. The first mounting holes 111 are in the lower layer, and the second mounting holes 112 are in the upper layer. The light curtain 3 covers the first mounting holes 111. The sealing strip body 1 is fixedly connected to the car door side 2 through the first connector 4 passing through the first mounting hole 111. The light curtain 3 is detachably connected to the car door side 2 through the second connector 5 passing through the second mounting hole 112. Preferably, the first connector 4 is a rivet, which is riveted to the car door, which is beneficial for large-scale production and transportation; the second connector 5 is fixed with bolts and nuts, which is convenient for on-site installation and replacement of the light curtain 3. The first mounting hole 111 is located at the front end of the second mounting hole 112, close to the light-shielding part 12.

[0039] In one embodiment, refer to 3- Figure 6 As shown, the connecting part 11 has a snap-fit ​​groove 113, and the light-shielding part 12 is partially embedded in the groove 113. The cross-section of the groove 113 includes circular, dovetail, and square shapes.

[0040] In one embodiment, both the first light-shielding part 12 and the second light-shielding part 12 are provided with an R-angle 13, which is adapted to the side of the car door 2.
