The first base 14 is secured by second anchor bolts 15, providing a sturdy mounting foundation for the slide rail 16 and ensuring it will not shift or wobble during long-term use. This stability ensures that the second fixed shaft 10, under the action of the tensioning mechanism, can slide smoothly in the predetermined direction, effectively preventing problems such as uneven installation of the banner 22 due to uneven sliding or offset, further improving the quality of the banner 22's fixation and display effect. Furthermore, the dual slide rails 16 and dual sliders 13 structure also share the weight of the second fixed shaft 10 and banner 22, extending the device's service life.

[0036] In a preferred embodiment of this embodiment, the sliding assembly further includes a first base 14 and a second anchor bolt 15. The first base 14 is fixedly connected between the fixed frame 4 and the first fixed shaft 21 via the second anchor bolt 15. There are two slide rails 16 and two sliders 13. The two slide rails 16 are arranged in parallel, with one end of the slide rail 16 fixedly connected to the first base 14 and the other end fixedly connected to the fixed frame 4. The sliders 13 are slidably connected to the corresponding slide rails 16, and both sliders 13 are fixedly connected to the second fixed shaft 10. The design of two parallel slide rails 16 and sliders 13 enhances the stability of the movement of the second fixed shaft 10. The first base 14 is fixed by the second anchor bolt 15, providing a solid mounting base for the slide rails 16, ensuring that the slide rails 16 will not shift or wobble during long-term use.

At the same time, the double slide rails 16 and double slide members 13 structure also share the weight of the second fixed shaft 10 and the banner 22, thereby extending the service life of the device.

[0037] In a preferred solution of this embodiment, it also includes a rotating shaft 11, which is arranged on the side of the second fixed shaft 10 close to the first fixed shaft 21, and the rotating shaft 11 can rotate around its axis. The rotating shaft 11 is used to be detachably fixedly connected to the end of the banner 22 away from the first fixed shaft 21.

[0038] In a preferred solution of this embodiment, a second base 12 and a fixer 9 are also included. One end of the second base 12 is fixedly connected to the bottom end of the second fixed shaft 10, and the other end is rotatably connected to the rotating shaft 11. One end of the fixer 9 is used for the top limit connection of the second fixed shaft 10, and the other end is rotatably connected to the rotating shaft 11. The cooperation between the second base 12 and the fixer 9 enhances the stability and structural strength of the connection between the rotating shaft 11 and the second fixed shaft 10. The second base 12 provides a stable support point for the rotating shaft 11, making it more stable and less likely to shake during rotation. The fixer 9 limits the top end of the second fixed shaft 10 to prevent the second fixed shaft 10 from deflecting or shaking under the action of tension, thereby ensuring the stability of the entire device structure. This stable connection structure helps to ensure the normal operation of the rotating shaft 11 and the second fixed shaft 10 under various working conditions, and better achieves the fixation of the banner 22.

[0039] In a preferred embodiment of the present invention, the second base 12 is provided with a first rotating column, the bottom end of the rotating shaft 11 is sleeved on the second rotating column and is rotatably connected to the second rotating column, one end of the fixer 9 is provided with a second rotating column, and the other end is provided with a rectangular column, and the top end of the second fixed shaft 10 is provided with a rectangular hole matching the rectangular column, the rectangular column is used to be inserted into the rectangular hole, and the second rotating column is used to be inserted into the top end of the rotating shaft 11 and is rotatably connected to the rotating shaft 11. The cooperation between the first rotating column on the second base 12 and the bottom end of the rotating shaft 11 makes the rotation of the rotating shaft 11 smoother and the positioning more accurate. The connection between the second rotating column on the fixer 9 and the top end of the rotating shaft 11 and the rectangular column and the rectangular hole at the top end of the second fixed shaft 10 effectively limits the rotation of the rotating shaft 11 relative to the second fixed shaft 10, providing reliable structural support for the fixation of the banner 22.

[0040] In a preferred embodiment of the present invention, a semicircular handle is provided at the top of the holder 9. The provision of the semicircular handle greatly facilitates the operator to operate the holder 9. By holding the semicircular handle, the operator can easily install the rotating shaft 11 and the second fixed shaft 10, which reduces the operator's work difficulty and improves work efficiency.

[0041] In a preferred embodiment of the present invention, two third bases 20, a plurality of third anchor bolts 18, and two pins 19 are further included. The two third bases 20 are respectively mounted on the wall. Parallel limit plates are fixedly connected to the third bases 20. A first pin hole 17 is provided in the middle of the limit plate. Second pin holes are provided at the top and bottom ends of the first fixed shaft 21. The pins 19 are used to pass through the first and second pin holes to secure the top and bottom ends of the first fixed shaft 21 to the two third bases 20, respectively. The cooperation between the two third bases 20 and the pins 19 further enhances the stability of the connection between the first fixed shaft 21 and the wall. By passing the pins 19 through the first pin holes 17 on the limit plates and the second pin holes on the first fixed shaft 21, the first fixed shaft 21 is securely fixed between the two third bases 20, preventing the first fixed shaft 21 from shifting up and down, shaking, or rotating, thereby ensuring the reliability of the first fixed shaft 21 securing one end of the banner 22. The plurality of third anchor bolts 18 ensure a stable connection between the third base 20 and the wall, so that the entire device can better withstand the tension of the banner 22 and improve the overall stability of the device during long-term use.

[0042] The present invention also provides a method for using the special device for fixing the banner 22 as described above, comprising the following steps:

[0043] Installation Preparation: Thoroughly inspect all components to ensure they are free of damage, deformation, or other defects. Prepare the necessary tools, such as screwdrivers and wrenches. Determine the installation locations for each component based on the actual use scenario and installation location, and mark them accordingly.

[0044] Fix the first fixed shaft 21

[0045] The two third bases 20 are respectively installed at the marked positions on the wall and are firmly fixed by a plurality of third anchor bolts 18. During the installation process, it is necessary to ensure that the limit plates arranged in parallel on the third bases 20 are in a horizontal and parallel state.

[0046] Align the second pin holes at the top and bottom of the first fixing shaft 21 with the first pin hole 17 in the middle of the limiting plate, and then insert the pin 19 through the corresponding pin holes to firmly fix the first fixing shaft 21 between the two third bases 20. This step ensures a firm connection between the first fixing shaft 21 and the wall, providing a stable foundation for the subsequent fixing of the banner 22.

[0047] Installing the Slide Assembly

[0048] At a marked position on the wall between the fixing bracket 4 and the first fixing axis 21 , the first base 14 is installed using the second anchor bolts 15 , ensuring that the first base 14 is securely and levelly installed.

[0049] One end of the two parallel slide rails 16 is firmly connected to the first base 14, and the other end is connected to the fixing frame 4. The installation of the slide rails 16 must ensure that they are consistent with the unfolding direction of the banner 22, and the two slide rails 16 are well parallel to each other.

[0050] A slider 13 is mounted on each rail 16, allowing it to slide smoothly. Then, both sliders 13 are fixedly connected to the second fixed shaft 10, ensuring a secure and reliable connection. This series of operations provides a stable track for the sliding of the second fixed shaft 10, ensuring smooth and stable deployment of the banner 22.

[0051] Build the tensioning mechanism

[0052] Securely install the fixed block 1 on the wall on the side of the second fixed axis 10 away from the first fixed axis 21, and then rotatably connect the rotating crank 2 to the fixed block 1 to ensure that the rotating crank 2 can rotate flexibly. Tightly wrap one end of the first steel wire rope 23 around the rotating crank 2, leaving the other end reserved for connection to subsequent components.

[0053] The fixing bracket 4 is installed on the wall surface on the side of the fixing block 1 facing the second fixing axis 10 using the first anchor bolt 6 to ensure that the fixing bracket 4 is firmly installed and accurately positioned.

[0054] A combined wheel 7 is installed in the middle of the fixing frame 4, and a first tensioning wheel 5 and a second tensioning wheel 5 are installed at the upper and lower ends of the fixing frame 4 respectively. During the installation process, it is necessary to ensure that each wheel rotates flexibly without any jamming.

[0055] Securely connect one end of the second steel wire rope 8 to the second fixed shaft 10. Then, loop the other end around the first tensioning wheel 5 and the combined pulley 7, and finally securely connect it to the steel wire rope clamp 3. Similarly, securely connect one end of the third steel wire rope to the second fixed shaft 10, and loop the other end around the second tensioning wheel 5 and the combined pulley 7, then securely connect it to the steel wire rope clamp 3. Finally, securely connect the side of the steel wire rope clamp 3 facing away from the fixed frame 4 to the first steel wire rope 23, which is wrapped around the rotating crank 2, completing the complex tensioning mechanism. This structure ensures that the second fixed shaft 10 can be pulled forcefully and evenly during subsequent use, smoothly tightening the banner 22.

[0056] Set the rotating shaft 11, the second base 12 and the fixer 9

[0057] The rotating shaft 11 is installed at a suitable position on one side of the second fixed shaft 10 close to the first fixed shaft 21 , and ensures that the rotating shaft 11 can rotate freely around its own axis and rotate smoothly without obstruction.

[0058] One end of the second base 12 is firmly connected to the bottom end of the second fixed shaft 10, and the other end is rotationally connected to the bottom end of the rotating shaft 11, specifically by sleeve-mounting the bottom end of the rotating shaft 11 on the first rotating column provided on the second base 12, ensuring that the rotational connection between the two is smooth and reliable.

[0059] Inserting the second rotating column at one end of the holder 9 into the top of the rotating shaft 11 achieves a flexible rotational connection with the rotating shaft 11. Inserting the rectangular column at the other end into the matching rectangular hole at the top of the second fixed shaft 10 completes the position-limiting connection with the top of the second fixed shaft 10. The semicircular handle at the top of the holder 9 can be used as an operating handle.

[0060] Banner 22 fixing and unfolding

[0061] One end of the banner 22 is detachably connected to the first fixed shaft 21 , and various detachable connection methods such as hooks and clips can be used to ensure a firm connection and easy removal of the banner 22 .

[0062] The other end of the banner 22 is detachably connected to the rotating shaft 11 , and attention should be paid to the flatness and alignment of the banner 22 during the connection.

[0063] Rotating the crank handle 2 causes the first wire rope 23 to wind or unwind. Since the first wire rope 23 is connected to the wire rope clamp 3 and, via the second and third wire ropes, to the second fixed shaft 10, it pulls the second fixed shaft 10 away from the first fixed shaft 21. During this process, the slider 13 slides along the rail 16, gradually unwinding and stretching the banner 22 to the desired flatness and tension. During operation, closely monitor the status of the banner 22 and stop rotating the crank handle 2 when the desired effect is achieved.

[0064] Device disassembly and storage

[0065] After use, if the banner 22 needs to be removed, first rotate the rotary crank 2 in the opposite direction to release the tension of the first steel wire rope 23, so that the banner 22 is gradually relaxed.

[0066] The detachable connections between the banner 22 and the first fixed shaft 21 and the rotating shaft 11 are released respectively, and the banner 22 is removed.

[0067] If the device needs to be completely disassembled, remove the connections of each component in the reverse order of installation, such as pin 19, anchor bolts, etc., and store the components properly for next use.

[0068] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
