Technical Field

[0001] This application relates to the field of elevator technology, and in particular to an anti-slip connecting pad for an elevator guide rail bracket with a convenient installation and an internal serrated structure. Background Technology

[0002] With the increasing prevalence of elevators, the stability of the guide rail supports installed in elevator shafts is crucial because they must withstand long-term vibration and impact. Generally, welding is required after installation. However, using serrated anti-slip pads on elevator guide rail supports can eliminate the need for welding, significantly reducing installation time and fire risk.

[0003] However, the existing convenient installation type internal serrated structure elevator guide rail bracket anti-slip connection pads have the following defects: For example, because the outer diameter of the ordinary standard internal serrated pad is smaller than that of the ordinary flat pad, after installation, the flat pad completely covers the internal serrated pad, making it impossible for inspectors to judge from the appearance whether the installer has installed the internal serrated pad as required, which poses a quality risk of not installing as required. Summary of the Invention

[0004] The purpose of this application is to avoid omissions or under-filling, and to reduce potential overall quality risks.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a convenient installation type internal serrated structure elevator guide rail bracket anti-slip connecting pad, including an outer ring, of which there are two outer rings, and an inner ring is fixedly connected to the inner wall of each of the two outer rings.

The inner wall of the first connecting plate is provided with a sliding groove, and there are two sliding grooves. A slider is provided inside the first connecting plate. Sliding rods are fixedly connected to the front and rear outer walls of the slider. The two sliding rods are respectively located inside the two sliding grooves. A rotating groove is provided on the right outer wall of the slider. A rotating block is movably connected to the inner wall of the rotating groove. A second connecting plate is fixedly connected to the right outer wall of the rotating block. The other end of the second connecting plate is fixedly connected to the outer wall of the right outer ring.

[0006] As a preferred embodiment, the upper and lower ends of the plurality of saw teeth are provided with protruding teeth, and the number of protruding teeth is plurality of each.

[0007] As another preferred embodiment, each of the two inner rings is provided with a bolt, the outer wall of the bolt is fitted with a flat washer, and there are two flat washers. The outer wall of the bolt is threaded with a nut.

[0024] like Figure 1-5The convenient installation type internal serrated structure elevator guide rail bracket anti-slip connecting pad shown includes an outer ring 1, there are two outer rings 1, and an inner ring 2 is fixedly connected to the inner wall of each outer ring 1. The inner wall of the inner ring 2 is provided with serrations 3, and there are multiple serrations 3. The outer wall of the left outer ring 1 is fixedly connected to a first connecting plate 4. The inner wall of the first connecting plate 4 is provided with a sliding groove 5, and there are two sliding grooves 5. A slider 6 is provided inside the first connecting plate 4. The front and rear outer walls of the slider 6 are fixedly connected to sliding rods 7. The two sliding rods 7 are located inside the two sliding grooves 5 respectively. The right outer wall of the slider 6 is provided with a rotating groove 8. The inner wall of the rotating groove 8 is movably connected to a rotating block 9. The right outer wall of the rotating block 9 is fixedly connected to a second connecting plate 10. The other end of the second connecting plate 10 is fixedly connected to the outer wall of the right outer ring 1. The upper and lower ends of the multiple serrations 3 are provided with protruding teeth 11, and there are multiple protruding teeth 11.

[0025] A first connecting plate 4 is connected to the right outer wall of the left outer ring 1, and a second connecting plate 10 is connected to the left outer wall of the right outer ring 1. When the two inner rings 2 are respectively fitted onto the outside of the two bolts 12, the connection status of the first connecting plate 4 and the second connecting plate 10 allows inspectors to visually determine whether the installers have installed the inner serrated gasket as required, avoiding omissions or under-installation and reducing overall quality risks. The left end of the second connecting plate 10 is connected to a rotating block 9. The rotating block 9 is movably connected by a slider 6, and the sliding rods 7 connected to the outer walls at both ends of the slider 6 can slide along the two grooves 5 opened on the inner wall of the first connecting plate 4. This allows the second connecting plate 10 to drive the rotating block 9 and the slider 6 to move within the first connecting plate 4, thereby adapting to bolt holes with different spacings. When the gasket is not in use, the first connecting plate 4 and the second connecting plate 10 can be easily folded together for easy carrying. This gasket has a simple structure, is suitable for different types of elevator installation occasions, and is easy and quick to install.

[0026] Bolts 12 are provided inside both inner rings 2. Flat washers 13 are fitted on the outer wall of the bolts 12, and there are two flat washers 13. Nuts 14 are threadedly connected to the outer wall of the bolts 12.

[0027] Two flat washers 13 in the same group are located above and below the inner ring 2 of the same group, and are both located inside the outer ring 1, so that the upper and lower ends of the saw teeth 3 can contact the upper and lower flat washers 13 to limit the flat washers 13, so that the flat washers 13 will not be displaced when the bolt 12 and nut 14 are tightened. In addition, multiple protruding teeth 11 are provided at the upper and lower ends of the saw teeth 3, so that the two flat washers 13 can prevent the bolt 12 from being turned by the multiple saw teeth 3 in the same group, and the two flat washers 13 rotate together with the bolt 12.

[0028] Two flat washers 13 in the same group are located inside the two outer rings 1 respectively, and two inner rings 2 are located in the middle of the two flat washers 13 in the same group respectively. A connector 15 is provided in the middle of the two flat washers 13, and there are two connectors 15. Two bolts 12 pass through the two connectors 15 in sequence. Multiple flat washers 13 are located at the upper end of the upper connector 15, and nuts 14 are located at the bottom end of the lower connector 15.

[0029] Working principle: When installing the washer, multiple flat washers 13 and two inner rings 2 are respectively fitted onto the outer walls of two bolts 12, ensuring that the two flat washers 13 in the same group are respectively located inside the corresponding outer rings 1, one above the other. Then, the two bolts 12 are respectively passed through the two inner rings 2. Finally, nuts 14 are threaded onto the bottom of the two bolts 12. The connection between the bolts 12 and the nuts 14 presses the inner rings 2 into the inside of the two flat washers 13. A first connecting plate 4 is connected to the right outer wall of the left outer ring 1, and a second connecting plate 10 is connected to the left outer wall of the right outer ring 1. When the two inner rings 2 are respectively fitted onto the outside of the two bolts 12, they can be pressed together according to the first connecting plate 10. The connection status between plate 4 and the second connecting plate 10 allows inspectors to visually determine whether the installers have installed the serrated gaskets as required, avoiding omissions or under-installation and reducing potential overall quality issues. The left end of the second connecting plate 10 is connected to a rotating block 9. The rotating block 9 is movably connected by a slider 6, and the sliding rods 7 connected to the outer walls at both ends of the slider 6 can slide along the two grooves 5 opened on the inner wall of the first connecting plate 4. This allows the second connecting plate 10 to drive the rotating block 9 and the slider 6 to move within the first connecting plate 4, thereby adapting to bolt holes with different spacings. Furthermore, when the gaskets are not in use, the first connecting plate 4 and the second connecting plate 10 can be easily folded together for convenient carrying.
