[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figures 1-4 As shown, this utility model provides a fall arrest fastening connector for an oil platform, including three first connectors 1 and three second connectors 2. The three first connectors 1 and the three second connectors 2 are all fixed together by connecting blocks 3. Mounting plates 9 are fixed to both sides of one end of the first connectors 1 and the second connectors 2. A second bolt 10 is provided in each of the two mounting plates 9. The output end of the second bolt 10 passes through the two mounting plates 9 and is threadedly connected to a nut 11. A stabilizing plate 12 is provided at the end of the nut 11 away from the mounting plate 9. A driving structure 13 for driving the stabilizing plate 12 to move is provided at one end of one of the mounting plates 9.

[0023] The overall effect of Embodiment 1 is that, through the arrangement of three first connectors 1 and three second connectors 2, and each first connector 1 and second connector 2 is connected by multiple connecting blocks 3, the arrangement of three first connectors 1 and three second connectors 2 makes the main body of the connector not a single-ring design, but a multi-ring design, which strengthens its overall strength. Through the arrangement of mounting plate 9, first bolt 7 and nut 11, two mounting plates 9 are fixed together, thereby sealing the cavity between the three first connectors 1 and three second connectors 2, which can be sleeved. Through the operation of the drive structure 13, the stabilizing plate 12 can be driven to move, so that one end of the stabilizing plate 12 can abut against the nut 11, preventing the nut 11 from accidentally moving and falling off, thus making the stability stronger.

[0024] Example 2, as Figures 1-4As shown, the drive structure 13 includes a bracket 1301 fixed to one end of one of the mounting plates 9. A screw 1302 is provided inside the bracket 1301. One end of the stabilizing plate 12 is threadedly connected to the screw 1302. The other end of the stabilizing plate 12 is slidably connected to a limit post 1303. A connecting post 14 is fixed to one end of the screw 1302. The end of the connecting post 14 away from the screw 1302 passes through the bracket 1301 and is fixed to a rotating plate 16. A damping ring 15 is installed inside the bracket 1301. The connecting post 14 is rotatably connected to the bracket 1301 through the damping ring 15. The outer wall of the rotating plate 16 is fixed with a damping ring 15. A friction-enhancing sleeve 17 is provided. The other end of the screw 1302 is rotatably connected to the bracket 1301. Both ends of the limiting post 1303 are fixed to the bracket 1301. Both ends of the outermost first connecting member 1 and the second connecting member 2 are provided with adjusting sleeves 4. One end of the adjusting sleeve 4 is fixed with a locking block 5. The locking block 5 is fixed to its corresponding first connecting member 1 or second connecting member 2 by a first bolt 7. The opposite ends of the outermost first connecting member 1 and the second connecting member 2 are provided with locking grooves 6 that match the locking block 5. A connecting rope 8 is fixed between the two sets of first connecting members 1. There are multiple connecting ropes 8.

[0025] The overall effect of Embodiment 2 is that by setting multiple connecting ropes 8, the instability of the traditional single rope setting is avoided. When one rope is damaged, the other connecting ropes 8 can still be used for support, resulting in greater stability. In addition, by rotating the rotating plate 16, the user drives the connecting column 14 to rotate, which in turn drives the screw 1302 to rotate. This allows the stabilizing plate 12 to move under the limit of the limiting column 1303. When the stabilizing plate 12 moves to one side of the nut 11 and abuts against the nut 11, it can assist in limiting the position of the nut 11, preventing the nut 11 from accidentally rotating and falling off, thus increasing stability. The setting of the adjusting sleeve 4 can control the width of the cavity between the first connecting member 1 and the second connecting member 2, making it easy to fit different things. Furthermore, the setting of the first bolt 7 allows for the installation and removal of the adjusting sleeve 4, making it easy to replace different models of the adjusting sleeve 4.

[0026] Working principle: In use, this device employs three first connecting parts 1 and three second connecting parts 2, each connected by multiple connecting blocks 3. This arrangement of three first connecting parts 1 and three second connecting parts 2 results in a multi-ring design for the main body of the connectors, enhancing overall strength. Furthermore, the use of multiple connecting ropes 8 avoids the instability of traditional single-rope designs. Even if one rope is damaged, the other connecting ropes 8 can still provide support, further improving stability. Additionally, the device utilizes the user to rotate the rotating plate 16, which in turn drives the connecting column 14. The rotation drives the screw 1302 to rotate, allowing the stabilizing plate 12 to move under the limit of the limiting post 1303. When the stabilizing plate 12 moves to one side of the nut 11 and abuts against the nut 11, it can assist in limiting the position of the nut 11, preventing the nut 11 from accidentally rotating and falling off, thus improving stability. The mounting plate 9, the first bolt 7, and the nut 11 are used to fix the two mounting plates 9 together, thereby sealing the cavity between the three first connecting parts 1 and the three second connecting parts 2. One of them is fitted onto the oil platform, and the other is fitted onto the user's waist hook.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
