Description

Technical Field

[0001] This utility model relates to the field of pennant protection tube technology, and in particular to a pennant protection tube. Background Technology

[0002] A banner is a traditional Chinese element, typically used for commendation, gratitude, or celebration. Made of silk or other materials, it is embroidered with text and designs, often expressing respect, gratitude, or celebrating achievements. The text on the banner is usually frontal, such as "High Medical Ethics," "Saving Lives and Healing the Wounded," or "Attentive Service," while the designs may include auspicious elements like dragons, phoenixes, flowers, and birds. Some banners also carry rich historical information and cultural connotations; for example, banners from the War of Resistance Against Japan are symbols of honor and carry revolutionary significance, thus requiring protection.

[0003] By protecting these banners that can pass on cultural heritage, the imprint of history can be continued, allowing more people to understand the profound cultural connotations behind them. Currently, banners usually lack dedicated protective devices, or existing protective devices do not have a fixed storage method. Simply stacking them in filing cabinets can easily lead to sticking, damage, and other problems. Therefore, this utility model proposes a banner protective tube to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a banner protection tube.

[0005] To achieve the above objectives, this utility model provides a pennant protective tube, comprising a pennant protective tube, wherein both ends of the pennant protective tube are detachably sealed with sealing cap assemblies, the sealing cap assembly including a sealing plug, the sealing plug being disposed inside the end of the pennant protective tube, pennant fixing blocks being respectively inserted on both sides of the inside of the pennant protective tube, pennant positioning holes being opened on the inner side of the pennant fixing blocks, and a plurality of threaded holes being circumferentially opened on the inner side of the pennant fixing blocks, at least three of which are provided, the threaded holes communicating with the pennant positioning holes, a threaded rod being threaded in the threaded holes, an arc-shaped block being rotatably disposed at the bottom end of the threaded rod via a rotating shaft, and a square locking hole being opened at the top end of the threaded rod, and a plurality of positioning holes being circumferentially opened on the outer side of the pennant fixing blocks, the positioning holes communicating with the threaded holes, a pennant rod being inserted between two of the positioning holes, and a pennant being wrapped around the pennant rod.

[0006] Furthermore, a plug is provided inside the positioning hole, a telescopic rod is fixedly provided at the bottom of the plug, a first magnetic block is fixedly provided at the bottom end of the telescopic rod, and a second magnetic block is fixedly provided at the bottom of the square card hole. The first magnetic block and the second magnetic block are magnetically attracted to each other.

[0007] Furthermore, telescopic columns are fixedly installed on both sides of the back of the arc-shaped block. The telescopic columns are fixedly installed in the vertical groove, which is opened on the inner wall of the pennant fixing block and communicates with the pennant positioning hole.

[0008] Furthermore, the sealing cap assembly also includes a disc assembly, which includes a disc fixedly disposed on the outside of the sealing plug. A sealing ring is fixedly disposed on the side of the disc near the sealing plug. The sealing ring is fixedly sleeved on the end of the sealing plug. The sealing ring is made of rubber. The disc is matched with the pennant protection cylinder for limiting. A transparent identification plate is affixed to the outside of the disc.

[0009] Furthermore, the banner protection tube includes a base layer made of Oxford paper, a buffer layer fixedly disposed on the outer layer of the base layer, a reinforcing layer fixedly disposed on the inner side of the base layer, and a waterproof membrane fixedly disposed on the inner side of the reinforcing layer.

[0010] Furthermore, an adjustment handle is fixedly provided on the outer side of the pennant fixing block. The adjustment handle includes a support rod, which is fixedly connected to the pennant fixing block. A ball-holding block is fixedly provided at the end of the support rod away from the pennant fixing block.

[0011] Furthermore, the pennant fixing block includes a block body, and a piston sleeve is fixedly fitted on the outer side of the block body. The longitudinal section of the block body is circular.

[0012] Furthermore, a rotating shaft is fixedly provided at the bottom end of the threaded rod, and the end of the rotating shaft away from the threaded rod is rotatably connected to the arc-shaped block.

[0013] Furthermore, a pull rope is fixedly installed on the top of the plug.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Using a structure including a protective sleeve, positioning holes, threaded rods, arc-shaped blocks, and a first magnetic block, the banner cover is placed over the banner's outer surface. The banner is then rolled up around the banner pole. Before placing the banner into the protective sleeve, both ends of the banner pole are inserted into the positioning holes inside the banner fixing blocks. An external tool is inserted into the square locking hole, and the threaded rod is rotated inward. The threaded rod moves the arc-shaped blocks towards the center of the positioning hole. The three arc-shaped blocks abut against the outer wall of the banner pole's end. The telescopic rod extends, allowing the first magnetic block to enter the square locking hole and magnetically attract and fix with the second magnetic block. This ensures that the three arc-shaped blocks tightly secure both ends of the banner pole, preventing the banner pole from being inserted into the protective sleeve. If the pennant shakes after entering the pennant protection tube, insert the plug into the positioning hole to restrict the rotation of the threaded rod. Insert one pennant fixing block into the pennant protection tube, place the pennant inside, insert one end of the pennant rod into the square locking hole, and then insert the other pennant fixing block into the pennant protection tube. Hold the adjustment handle and push the pennant fixing block to fix the pennant in place, ensuring that the pennant no longer shakes. After the pennant is fixed, place the two sealing plugs on the inside of the end of the pennant protection tube to preserve the pennant. This solves the problem that existing pennant protection devices do not have a fixed preservation mode and simply stacking them in the filing cabinet can easily lead to problems such as sticking and damage.

[0016] 2. Through the design of sealing rings and discs, the disc engages with the protective tube of the banner for positioning. After the sealing plug is inserted, the sealing ring, acting on the disc, presses against the end of the protective tube. With the sealing plug already in place, the sealing ring further assists in sealing, improving the sealing effect. A transparent label provides detailed information about the banner, such as the donor, year, and banner content, facilitating easy identification.

[0017] 3. The base layer is made of Oxford paper, and the inner wall is coated with a waterproof membrane, which makes the pennant protective tube have good waterproofness and durability. It can effectively isolate external moisture and prevent pennants from getting damp and moldy in humid environments. The reinforcing layer and buffer layer can withstand a certain degree of compression and impact, and play a buffering protection role in pennant storage. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order.

[0032] Please see Figure 1-9 A banner protection tube includes a banner protection tube 1. Both ends of the banner protection tube 1 are detachably sealed with sealing cap assemblies, primarily used to seal the opening of the protection tube, thus preventing dust, moisture, insects, and other external substances from entering the tube and providing a relatively stable and clean storage environment for the banner. The sealing cap assembly includes a sealing plug 3, which is inserted into the inner side of the end of the banner protection tube 1. Banner fixing blocks 5 are respectively inserted into both sides of the inside of the banner protection tube 1. Each banner fixing block 5 includes a block body 52, and a piston sleeve 51 is fixedly fitted onto the outer side of the block body 52. ​​The piston sleeve 51 is made of polyurethane (PU) foam material and has a certain frictional force with the inner wall of the protection tube. Operators can manually apply external force to push or pull the banner fixing block 5, moving it to a suitable position along the inner wall of the protection tube.

[0033] The longitudinal section of block 52 is circular. A pennant positioning hole 7 is provided on the inner side of the pennant fixing block 5. An adjusting handle 4 is fixedly provided on the outer side of the pennant fixing block 5. The adjusting handle 4 includes a support rod, which is fixedly connected to the pennant fixing block 5. A ball-grip is fixedly provided at the end of the support rod away from the pennant fixing block 5 for easy gripping and pushing / pulling. Several threaded holes 14 are annularly provided on the inner side of the pennant fixing block 5, with at least three threaded holes 14. The threaded holes 14 communicate with the pennant positioning hole 7. A threaded rod 15 is threaded inside the threaded hole 14. A square locking hole 24 is provided at the top of the threaded rod 15. An arc-shaped block 19 is rotatably provided at the bottom end of the threaded rod 15 via a rotating shaft 18. A rotating shaft 18 is fixedly provided at the bottom end of the threaded rod 15. The rotating shaft 18 is located away from the threaded rod 15. One end of the threaded rod 15 is rotatably connected to the arc-shaped block 19. Telescopic columns 17 are fixedly installed on both sides of the back of the arc-shaped block 19. The telescopic columns 17 are fixedly installed in the vertical groove 16. The vertical groove 16 is opened on the inner wall of the pennant fixing block 5. The vertical groove 16 communicates with the pennant positioning hole 7. After the pennant cover (conventional polyethylene plastic material) is put on the outer surface of the pennant 6, the pennant 6 is rolled up around the pennant rod 8. Before the pennant 6 is put into the pennant protective tube 1, the two ends of the pennant rod 8 are respectively inserted into the pennant positioning hole 7 on the inner side of the pennant fixing block 5. The square card hole 24 is inserted through an external tool, and the threaded rod 15 is rotated inward. The threaded rod 15 drives the arc-shaped block 19 to move towards the center of the pennant positioning hole 7. The three arc-shaped blocks 19 abut against the outer wall of the end of the pennant rod 8.

[0034] The outer side of the pennant fixing block 5 has several positioning holes 20 arranged in a ring. The positioning holes 20 communicate with the threaded holes 14. A pennant pole 8 is inserted between two positioning holes 20, and a pennant 6 is wrapped around the pennant pole 8. A plug 22 is set in the positioning hole 20. A pull rope 21 is fixedly set on the top of the plug 22, so that the plug 22 can be removed from the positioning hole 20 by pulling the rope 21. A telescopic rod 23 is fixedly set on the bottom of the plug 22. A first magnetic block 26 is fixedly set on the bottom end of the telescopic rod 23. A square locking hole 24 is fixedly set at the bottom. A second magnetic block 25 is provided, and the first magnetic block 26 and the second magnetic block 25 are magnetically attracted to each other. The telescopic rod 23 extends so that the first magnetic block 26 enters the square card hole 24 and is magnetically attracted to the second magnetic block 25. This allows the three arc-shaped blocks 19 to tightly hold the two ends of the pennant pole 8, preventing the pennant pole 8 from shaking after being placed in the pennant protection tube 1. Then, the plug 22 is inserted into the positioning hole 20 to restrict the rotation of the threaded rod 15. This makes it easy to adjust the size of the hole formed by the three arc-shaped blocks 19 according to the different sizes of the pennant pole 8.

[0035] Insert one of the pennant fixing blocks 5 into the pennant protective tube 1, place the pennant 6 into the pennant protective tube 1, insert one end of the pennant pole 8 into the square locking hole 24, then insert the other pennant fixing block 5 into the pennant protective tube 1, hold the adjusting handle 4 and push the pennant fixing block 5 so that the two pennant fixing blocks 5 fix the pennant 6 in place, ensuring that the pennant 6 no longer shakes. After the pennant 6 is fixed, insert the two sealing plugs 3 into the inner side of the end of the pennant protective tube 1 to preserve the pennant.

[0036] As an improvement to the above technical solution, the sealing cap assembly also includes a disc assembly 9. The disc assembly 9 includes a disc 91, which is fixedly disposed on the outside of the sealing plug 3. A sealing ring 92 is fixedly disposed on the side of the disc 91 near the sealing plug 3. The sealing ring 92 is fixedly sleeved on the end of the sealing plug 3. The sealing ring 92 is made of rubber. After being inserted into the sealing plug 3, the sealing ring 92, in conjunction with the disc 91, abuts against the end of the banner protective tube 1. While the sealing plug 3 provides a seal, the sealing ring 92 further assists in sealing, improving the sealing effect. The disc 91 and the banner protective tube 1 are mutually restrictive. A transparent label 2 is affixed to the outside of the disc 91. The transparent label 2 displays detailed information about the banner, such as the donor, year, and banner content, facilitating identification and retrieval.

[0037] As an improvement to the above technical solution, the banner protection tube 1 includes a base layer 12, a buffer layer 13 fixedly disposed on the outer layer of the base layer 12, and a reinforcing layer 11 fixedly disposed on the inner side of the base layer 12. Through the reinforced layer 11 and the buffer layer 13, the banner protection tube 1 can withstand a certain degree of compression and collision, and can play a buffering and protective role in the storage of banners. A waterproof membrane 10 is fixedly disposed on the inner side of the reinforcing layer 11. The base layer 12 is made of Oxford paper, and the inner wall of the tube is coated with the waterproof membrane 10, so that the inside of the banner protection tube 1 has good waterproofness and durability, can effectively isolate external moisture, and can prevent the banners from getting damp and moldy in a humid environment.

[0038] The working principle and usage of this utility model:

[0039] In use, after covering the outer surface of the banner 6 with a banner cover (made of conventional polyethylene plastic), roll the banner 6 around the banner pole 8. Before placing the banner 6 into the banner protective tube 1, insert both ends of the banner pole 8 into the banner positioning holes 7 inside the banner fixing block 5. Insert an external tool into the square locking hole 24 and rotate the threaded rod 15 inward. The threaded rod 15 drives the arc-shaped block 19 to move towards the center of the banner positioning hole 7. The three arc-shaped blocks 19 abut against the outer wall of the end of the banner pole 8. The telescopic rod 23 extends, allowing the first magnetic block 26 to enter the square locking hole 24 and magnetically attract and fix it to the second magnetic block 25. This allows the three arc-shaped blocks 19 to tightly hold both ends of the banner pole 8, preventing the banner pole 8 from shaking after being placed into the banner protective tube 1. Then, insert the plug 22 into the positioning hole 20 to restrict the threaded rod 15. The rotation of the pennant fixing block 5 inserts one of the pennant fixing blocks 5 into the pennant protective tube 1, and the pennant 6 is placed inside the pennant protective tube 1. One end of the pennant pole 8 is inserted into the square locking hole 24, and then the other pennant fixing block 5 is inserted into the pennant protective tube 1. The adjusting handle 4 is held to push the pennant fixing block 5 so that the two pennant fixing blocks 5 fix the pennant 6, ensuring that the pennant 6 no longer shakes. After the pennant 6 is fixed, the two sealing plugs 3 are inserted into the inner side of the end of the pennant protective tube 1 to preserve the pennant. The disc 91 is matched with the pennant protective tube 1 for limiting. After the sealing plug 3 is inserted, the sealing ring 92, under the action of the disc 91, abuts against the end of the pennant protective tube 1. Under the premise that the sealing plug 3 is sealing, the sealing ring 92 further plays an auxiliary sealing role, improving the sealing effect. A transparent sign 2 is provided to introduce the detailed information of the pennant. The banner includes information such as the donor, year, and content, making it easy to find and identify. The base layer 12 is made of Oxford paper, and the inner wall is coated with a waterproof membrane 10, giving the banner protective tube 1 good waterproofness and durability. It can effectively isolate external moisture and prevent the banner from getting damp and moldy in a humid environment. The reinforcing layer 11 and the buffer layer 13 allow the banner protective tube 1 to withstand a certain degree of compression and impact, providing cushioning protection during banner storage.
