AI Technical Summary
In existing technologies, the fixing methods for safety ropes have insufficient structural strength, and the single thread connection is not stable enough, making them prone to loosening or falling off under external impact, which threatens the safety of workers at heights.
The system employs a multi-locking structure, including threaded connection, pin hole limiting, and limiting screw fixing. The fixing ring is tightly connected to the internal threaded mating post through the threaded part. The first half pin groove and the second half pin groove are combined to form a pin hole for secondary limiting. The limiting screw passes through the front baffle, the internal threaded mating post, and is threadedly connected to the fixing ring to form a multi-locking structure. At the same time, reinforcing ribs are set between the load-bearing plate and the back plate to enhance the connection strength.
This improves the stability and resistance to loosening of the fixing ring, ensuring it is not easily loosened under external impact, enhancing the load-bearing capacity and overall stability of the hoisting base, and preventing safety accidents.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction safety facilities technology, and more specifically, to a prefabricated lifeline fixing ring. Background Technology
[0002] In high-altitude operations such as building curtain walls, the binding and securing of safety ropes is a crucial step. The traditional method of securing lifelines is to directly tie the safety rope to the roof structure. Although this method is simple and easy to implement, long-term exposure to wind and sun and friction and wear can seriously affect the safety and quality of the safety rope, and may even lead to safety accidents.
[0003] To improve this situation, existing technologies have attempted to fix lifelines by pre-embedding threaded bases in the wall and then using a safety ring to connect the threaded base with a thread. Compared with traditional binding methods, this method is simpler and more convenient to install and avoids the problem of safety rope wear caused by friction. However, although this method has certain convenience in installation and use, its structural strength is insufficient. The single thread connection makes the connection between the safety ring and the threaded base not stable enough. Once subjected to a large external impact, it may loosen or even fall off, thereby threatening the life safety of workers at height. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an assembled lifeline fixing ring to solve the aforementioned problems.
[0005] This utility model is implemented as follows:
[0006] An assembled lifeline fixing ring includes a pre-embedded base, a lifting base, a fixing ring, and a limiting screw. The pre-embedded base has several pre-embedded reinforcing bars on its rear side, and a first embedding groove on its top. The lifting base includes a back plate embedded in the first embedding groove. A load-bearing plate is provided on the front side of the back plate, and a movable hole is provided at the center of the top of the load-bearing plate. An annular positioning plate is provided on the top of the annular positioning plate, and an internally threaded docking post is provided on the top of the annular positioning plate. The annular positioning plate, the movable hole, and the internally threaded docking post are coaxial. The fixing ring extends from the bottom of the load-bearing plate to the top of the internally threaded docking post. A front baffle is provided on the front side of the load-bearing plate. The limiting screw sequentially passes through the front baffle and the internally threaded docking post and is threadedly connected to the fixing ring.
[0007] In an embodiment of this utility model, a mating hole is provided on the front side of the back plate near the top, and a pre-embedded screw sleeve is provided on the rear side of the pre-embedded base. The threaded hole inside the pre-embedded screw sleeve extends towards the front side of the pre-embedded base. After the back plate is inserted into the first embedding groove, the mating hole is coaxial with the pre-embedded screw sleeve, and a screw is used to fix it here.
[0008] In an embodiment of this utility model, a plurality of reinforcing ribs are provided between the bottom of the load-bearing plate and the back plate, and a second embedding groove with the same number of reinforcing ribs is opened on the front side of the pre-embedded base. When the back plate is inserted into the first embedding groove, any of the reinforcing ribs are respectively located in the corresponding second embedding groove.
[0009] In an embodiment of this utility model, the top and bottom of the internal threaded mating post are respectively provided with circular bosses of different sizes. The bottom circular boss is set on the top of the annular positioning plate. Several pressure plates are provided on the weighing platform, and one end of the pressure plate presses on the bottom circular boss to fix it.
[0010] In an embodiment of this utility model, a first half-pin groove is provided at the top threaded hole of the internal threaded mating post, the top of the fixing ring is a threaded part, and a second half-pin groove of the same size as the first half-pin groove is provided at the top of the fixing ring.
[0011] In an embodiment of this utility model, two side platforms are symmetrically opened on both sides of the fixing ring along the center, and a limiting threaded hole is provided through the center of the two side platforms, and the opening direction of the limiting threaded hole is perpendicular to the slotting direction of the second half pin groove.
[0012] In an embodiment of this utility model, a side boss is provided on one side of the internally threaded docking post. The extension direction of the side boss is perpendicular to the slotting direction of the first half-pin groove. A first through hole is provided on the side of the side boss away from the internally threaded docking post. A second through hole is provided on the front baffle. The fixing ring passes through the load-bearing plate and the internally threaded docking post in sequence, so that the top of the fixing ring and the top of the internally threaded docking post are on the same plane. At this time, the first half-pin groove and the second half-pin groove are arranged opposite to each other to form a complete pin hole. A square pin is inserted to limit its movement. Furthermore, the limiting screw passes through the second through hole and the first through hole in sequence and is threadedly connected to the limiting threaded hole on the fixing ring.
[0013] The beneficial effects of this utility model are as follows: This assembled lifeline fixing ring adopts a multi-locking structure, including threaded connection, pin hole limiting, and limiting screw fixing. The fixing ring is tightly connected to the internal threaded docking post through the threaded part to form a preliminary lock. Then, a square pin is inserted into the pin hole formed by the combination of the first half pin groove and the second half pin groove for secondary limiting. Finally, the limiting screw passes through the front baffle, the internal threaded docking post and the fixing ring are threaded together to form the final multi-locking structure. This design ensures that the fixing ring is not easy to fall off when subjected to external impact, which greatly improves its stability. Several reinforcing ribs are set between the bottom of the load-bearing plate and the back plate. These reinforcing ribs not only increase the load-bearing capacity of the hoisting base, but also improve its overall stability. At the same time, the front side of the pre-embedded base has a second embedding groove with the same number of reinforcing ribs. When the back plate is inserted into the first embedding groove, the reinforcing ribs will be embedded into the corresponding second embedding grooves, further enhancing the connection strength between the hoisting base and the pre-embedded base.

[0024] In this embodiment, a number of reinforcing ribs 2202 are provided between the bottom of the load-bearing plate 22 and the back plate 21. The front side of the pre-embedded base 10 is provided with a second embedding groove 13 with the same number of reinforcing ribs 2202. When the back plate 21 is inserted into the first embedding groove 12, any reinforcing rib 2202 is located in the corresponding second embedding groove 13.
[0025] like Figure 3-4 As shown, the top and bottom of the internal threaded mating post 25 are respectively provided with circular bosses of different sizes. The bottom circular boss is set on the top of the annular positioning plate 24. Several pressure plates 26 are provided on the weighing platform.
