Description

Technical Field

[0001] This solution belongs to the field of seat belt fastening technology, specifically involving a seat belt fastening point device. Background Technology

[0002] Utility model patent CN220917966U discloses a portable seat belt fastening point device, belonging to the field of seat belt fastening point technology. It addresses the problems of poor flexibility and convenience in fastening point devices, as well as inconvenient installation. The device includes a channel steel body, which also includes two angle steels symmetrically distributed inside the channel steel body. An adjusting component is provided between the two angle steels and the channel steel body. Multiple equidistant through holes 'a' are opened on the sidewalls of adjacent angle steels, and matching high-strength bolts are inserted through the through holes 'a'. This utility model, through the setting of the adjusting component, effectively adjusts the spacing between the two angle steels, making it suitable for installation on shear walls of different thicknesses. It avoids the wobbling that occurs when installing through pre-drilled holes in shear walls due to excessive width, ensuring better stability of the seat belt fastening point during use and preventing lateral swaying that could endanger the user. It has the advantages of high portability and high installation stability.

[0003] However, this device has certain shortcomings. The existing seat belt fastening point device is not convenient to operate, has a complex structure, and its safety performance is not high enough. Utility Model Content

[0004] The purpose of this solution is to provide a safety belt fastening point device to address the problems of inconvenient overall operation, complex structure, and insufficient safety performance of the device.

[0005] To achieve the above objectives, this solution provides a seat belt fastening point device, including a rod with a fastening ring at the right end and a reserved groove at the left end. A pin hole is provided inside the rod, and a rotating shaft is rotatably connected inside the pin hole. A gravity rotating pin is fixedly connected to the outside of the rotating shaft.

[0006] The principle of this solution is as follows: When in use, the tie bolt holes of the concrete structural wall or beam are used to insert the anchor point device straight into the tie bolt holes. The gravity-rotating pin automatically opens and locks due to the weight of the two ends of the rod, which can prevent the safety belt anchor point from coming off. After use, the device is flipped over, and the gravity-rotating pin automatically turns to a straight state, and the device can be pulled out.

[0007] The technical advantages of this solution are: the device is simple to manufacture, easy to use, safe and reliable. The device can be used to drill through the tie bolt holes left by the original process, and the gravity rotation pin of the device can automatically open and lock after being flipped and automatically turn to a straight state.

[0008] Furthermore, the rod is made of round steel with a diameter of 12mm. The rod serves as the main support structure for the device.

[0009] Furthermore, the hanging ring has a triangular structure, and the diameter of its inscribed circle is 100mm. The hanging ring is used to attach hooks.

[0010] Furthermore, the reserved groove is 100mm long. The reserved groove is designed to accommodate a gravity-driven rotating locking pin.

[0011] Furthermore, the pin hole and the reserved groove are connected, and the pin hole is located in the middle of the reserved groove. The pin hole is used to install a rotating shaft.

[0012] Furthermore, one end of the gravity-rotating locking pin is located within a pre-reserved groove. The gravity-rotating locking pin facilitates easy assembly and disassembly of the device on the wall. Attached Figure Description

[0016] The following detailed explanation illustrates the specific implementation methods:

[0017] The reference numerals in the accompanying drawings include: 1. Rod; 2. Hanging ring; 3. Reserved groove; 4. Rotating shaft; 5. Pin hole; 6. Gravity rotation lock pin. Detailed Implementation

[0018] The implementation examples are basically as follows Figures 1-3As shown, this embodiment provides a seat belt fastening point device, including a rod 1 made of round steel with a diameter of 12mm. The rod 1 serves as the main support of the device. A fastening ring 2 is provided at the right end of the rod 1. The fastening ring 2 has a triangular structure and the inner circle diameter of the fastening ring 2 is 100mm. The fastening ring 2 is used to fasten hooks. A reserved groove 3 with a length of 100mm is provided at the left end of the rod 1. The reserved groove 3 is used to accommodate a gravity rotating pin 6. A pin hole 5 is provided inside the rod 1. A rotating shaft 4 is rotatably connected inside the pin hole 5. The pin hole 5 and the reserved groove 3 are connected. The pin hole 5 is located in the middle of the reserved groove 3. The pin hole 5 is used to install the rotating shaft 4. A gravity rotating pin 6 is fixedly connected to the outside of the rotating shaft 4. One end of the gravity rotating pin 6 is located in the reserved groove 3. The gravity rotating pin 6 makes it easy to install and remove the device from the wall.

[0019] The specific implementation process of this utility model is as follows: During use, the fastening device is inserted horizontally into the tie bolt holes of the concrete structural wall or beam. The gravity-driven rotating locking pin 6 automatically opens and locks due to the weight of both ends of the rod 1, preventing the safety belt fastening point from coming off. After use, the device is rotated 180 degrees, and the gravity-driven rotating locking pin 6 automatically returns to a straight position, allowing the device to be pulled out.

[0020] The device is simple to manufacture, easy to use, safe and reliable. It can be used to drill through the tie bolt holes left in the original process. The gravity rotation pin 6 of the device can automatically open and lock after being rotated 180 degrees and automatically turn to a straight state.
