[0027] Furthermore, in a preferred embodiment, multiple fixing blocks 7 are fixedly installed on the upper and lower outer surfaces of the frame 1, and bolts 8 are installed through the interior of the fixing blocks 7.

[0028] Furthermore, in a preferred embodiment, a column 9 is fixedly installed in the middle of the interior of the frame 1, and a hook 10 is fixedly installed on the rear outer surface of the docking block 3.

[0029] Furthermore, in a preferred embodiment, a rotating shaft 11 is connected and installed on the front side of the docking block 3, and a pull ring 12 is fixedly installed on the outer surface of the rotating shaft 11.

[0030] Furthermore, in a preferred embodiment, the seat belt assembly 101 includes a pull strap 102 inside.

[0031] Furthermore, in a preferred embodiment, movable hooks 103 are fixedly installed on the upper and lower outer surfaces of the pull strap 102, and a safety hook 104 is connected and installed at the other end of the movable hooks 103.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0033] In addition to the above, the present invention also has the following embodiments:

[0034] In a further embodiment of the present invention, reference is made to Figures 1 to 3The system includes multiple frames 1 and a seat belt assembly 101. Multiple guide rails 2 are provided on the inner side of the frames 1. Connecting blocks 3 are fitted onto the outer surface of the frames 1. Slider 4 is fitted onto the inside of the connecting blocks 3. Hand screws 5 are threaded into the inside of the connecting blocks 3. Friction blocks 6 are threaded onto the other end of the hand screws 5. The operating principle is as follows: the frames 1 serve as the connection base between the seat belt and the public transport bollard, providing conditions for seat belt installation. The multiple frames 1 each cover half of the public transport bollard, facilitating installation and disassembly. The guide rails 2 limit the movement of the connecting components, preventing them from detaching from the outer surface of the frames 1, thus allowing for adjustments to the seat belt's fixing height. The connecting blocks 3 serve as the installation base for the connecting components. By moving the connecting blocks 3 within the outer surface of the frames 1, the fixing height of the seat belt can be adjusted, allowing for better securing of various items at different heights. The slider 4 restricts the connecting blocks 3, preventing them from detaching. The internal structure of frame 1 and guide rail 2 causes the seat belt assembly to disengage from the public transportation bollard. A combination of hand-tightening screw 5 and friction block 6 is used. Hand-tightening screw 5 connects docking block 3 and slider 4, allowing slider 4 to connect with docking block 3. Friction block 6 is driven by hand-tightening screw 5 to engage with guide rail 2. The threads of hand-tightening screw 5 are tightened clockwise, allowing the outer surface of friction block 6 to fix docking block 3 and slider 4 at corresponding heights through friction, preventing seat belt displacement due to changes in the height of the docking assembly. The threads between friction block 6 and hand-tightening screw 5 are tightened counterclockwise, preventing loosening between friction block 6 and hand-tightening screw 5 when it rotates. By installing a component for adjusting the fixed height of the seat belt in this device, passengers can adjust the fixed height of the seat belt according to the size and shape of their items, better securing various items and improving the flexibility and practicality of the seat belt.

[0035] In a further embodiment of the present invention, a plurality of fixing blocks 7 are fixedly installed on the upper and lower outer surfaces of the frame 1, and bolts 8 are installed through the interior of the fixing blocks 7.

[0036] In a further embodiment of the present invention, a plurality of fixing blocks 7 are fixedly installed on the upper and lower outer surfaces of the frame 1, and mounting bolts 8 penetrate the interior of the fixing blocks 7, as shown in the figure. Figure 1The device employs a combination of fixing blocks 7 and bolts 8. Fixing blocks 7 are used to fix both ends of the frame 1, ensuring that the frame 1 fits tightly against the public transportation bollard. Bolts 8 penetrate the interior of fixing blocks 7 to prevent the device from loosening and maintain the frame 1's fixation. After bolts 8 release the fixing blocks 7 from the frame 1, friction blocks 6 are loosened from the inside of the hand screws 5. Then, the hand screws 5 are rotated out from the internal threads of the connecting blocks 3 and sliders 4 to release the restriction between the connecting blocks 3 and sliders 4. The connecting blocks 3 are then slid out from the top of the frame 1. Finally, the two ends of the frame 1 are separated to complete the dismantling of the device, thus facilitating the relocation of the device by staff as needed.

[0037] In a further embodiment of the present invention, a column 9 is fixedly installed in the middle of the interior of the frame 1, and a hook 10 is fixedly installed on the rear outer surface of the connecting block 3.

[0038] In a further embodiment of the present invention, a column 9 is fixedly installed in the middle of the interior of the frame 1, and a hook 10 is fixedly installed on the rear outer surface of the connecting block 3, as shown in the figure. Figure 1 and Figure 3 The column 9, as the main part of the public transportation pile, is used to demonstrate the handrail column on public transportation such as buses and subways. It can indicate the installation position of the device. The inside of the hook 10 can provide conditions for hanging the rope and for connecting the other end of the safety belt assembly to the device itself.

[0039] In a further embodiment of the present invention, a rotating shaft 11 is connected and installed on the front side of the docking block 3, and a pull ring 12 is fixedly installed on the outer surface of the rotating shaft 11.

[0040] In a further embodiment of the present invention, a rotating shaft 11 is connected and installed on the front side of the docking block 3, and a pull ring 12 is fixedly installed on the outer surface of the rotating shaft 11, as shown in the figure. Figure 2 The rotating shaft 11 is used to drive the pull ring 12 to rotate around the front end of the docking block 3, providing conditions for changing the angle of the seat belt on the outer surface of the docking block 3. The pull ring 12 provides conditions for the connection between the seat belt assembly and the device.

[0041] In a further embodiment of the present invention, the seat belt assembly 101 includes a pull strap 102 inside.

[0042] In a further embodiment of the present invention, the seat belt assembly 101 internally includes a pull strap 102, as shown in the reference. Figure 1 and Figure 4 The seat belt assembly 101, as a major component of the seat belt assembly, is used to provide conditions for securing the cargo. The strap 102 can be wrapped around and tied to items such as suitcases to prevent the cargo from running out of its own limited range.

[0043] In a further embodiment of the present invention, movable hooks 103 are fixedly installed on the outer surfaces of the upper and lower sides of the pull strap 102, and a safety hook 104 is connected and installed at the other end of the movable hooks 103.

[0044] In a further embodiment of the present invention, movable hooks 103 are fixedly installed on the outer surfaces of the upper and lower sides of the pull strap 102, and a safety hook 104 is connected and installed at the other end of the movable hook 103, as shown in the figure. Figure 4 The movable hook 103 allows the pull strap 102 and the safety hook 104 to rotate to different angles, so that the pull strap 102 fits as close as possible to the outer surface of the goods, increasing the fixing effect. One end of the safety hook 104 fits into the pull ring 12, and the other end of the safety hook 104 can be hooked into the outer surface of the hook 10, ensuring that the pull strap 102 can stably fix the goods and prevent them from leaving its protective range.

[0045] In a further embodiment of the present invention, the guide rail 2 limits the movement of the connecting component to a certain range, preventing it from detaching from the outer surface of the frame 1, and providing conditions for changing the seat belt fixing height. The docking block 3 serves as the mounting base for the connecting component. By moving the docking block 3 against the outer surface of the frame 1, the seat belt fixing height can be adjusted, allowing it to better fix various items of different heights. The slider 4 can restrict the docking block 3 to prevent it from detaching from the frame 1 and the guide rail 2, thus preventing the seat belt assembly from disengaging from the public transportation bollard. By installing the component for adjusting the seat belt fixing height in this device, passengers are allowed to adjust the fixing height of the seat belt according to the size and shape of the items, which can better fix various items and improve the flexibility and practicality of the seat belt.

[0046] In a further embodiment of the present invention, since the columns 9 of public transportation are mostly vertically installed fixed structures, a left-right split structure is adopted on both the main mounting frame and the sliding assembly to cover the column 9 and facilitate the assembly of the safety belt. Specifically, the main mounting frame can be assembled by tightening multiple bolts 8. The fixing blocks 7 located at the upper and lower ends can limit the sliding assembly and prevent the sliding assembly from detaching from the main mounting frame. At the same time, the main mounting frame is provided with two axially arranged guide rails 2, and the slider 4 on each docking block 3 is slidably installed in one guide rail 2. Preferably, each frame 1 is welded to the fixing blocks 7 located at its upper and lower ends. The two connecting blocks 3 can be connected by welding or by screws. Specifically, the two ends of the connecting blocks 3 are provided with grooves for engaging the hook 10 or the base. The hook 10 and the base are respectively engaged at the two joint positions of the sliding assembly. The two connecting blocks 3 can be locked with screws to achieve clamping and limiting of the hook 10 and the base. One end of the rotating shaft 11 is rotatably mounted on the base, and the pull ring 12 is rotatably mounted on the end of the rotating shaft 11. The pull ring 12 is used to hook one end of the safety belt assembly 101. The other end of the safety belt assembly 101 can be hooked on the hook 10 of another item's safety belt. The hooking structure is adopted here to facilitate hanging and disassembly.

[0047] In a further embodiment of the present invention, both guide rails 2 are elongated through holes along the axial direction of the main mounting frame, used to limit the sliding direction and sliding distance of the sliding component. A friction block 7 is installed on the inner end face of each slider 4. By tightening the hand screw 5, the friction block 7 abuts against the outer surface of the column 9, increasing the friction of the contact surface, thereby locking and positioning the sliding component on the main mounting frame. This ensures that the sliding component will not slide along the main mounting frame during use of the safety belt assembly 101. When it is necessary to adjust the position of the sliding component, loosening the hand screw 5 will allow the sliding component to slide on the main mounting frame. When the sliding component slides to the next working position, tightening the hand screw 5 again will lock and position the sliding component again. The present invention has a simple overall structure, occupies little space, and is easy to adjust and operate.

[0048] In a further embodiment of the present invention, the pull strap 102 is an annular elastic tension strap, such as... Figure 4 As shown, it can stretch and lengthen after being subjected to force, and can also retract and reset after the external force is removed, thereby limiting the position of the object. The movable hook 103 is sleeved on the pull strap 102 and can slide freely along the pull strap 102. A safety hook 104 is rotatably installed on each movable hook 103 to facilitate adjustment of the suspension direction of the safety hook 104.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
