Description

Technical Field

[0001] The invention relates to the technical field of bamboo material processing, in particular to a round bamboo flagpole and a manufacturing method of the round bamboo pole. Background Art

[0002] Tour guides or team-building teams often need to carry a flagpole. While this can support the flag, it can't be adjusted in length, making it difficult to maintain and install, and even more difficult to carry. Furthermore, untreated round bamboo flagpoles are prone to cracking, mildew, and discoloration, resulting in a less durable decorative effect and a shorter lifespan.

[0003] In the existing market, telescopic poles for guiding flags are also available. These poles are generally made of stainless steel or aluminum alloy. After stretching two adjacent sleeves, they need to be locked with corresponding locking parts, or other accessories such as plastic parts are used to fix the adjacent sleeves together to form a stretched state. These telescopic poles have many defects and shortcomings. Specifically, stainless steel is heavy and unwieldy, and aluminum alloy requires other plastic parts for reinforcement. The high cost also makes the overall price high and unacceptable to the majority of consumers. These metal telescopic poles require a locking part to be installed on the corresponding sleeve, making the overall structure more complex, more cumbersome to use, and further increasing the cost. The gaps between the sleeves for telescoping allow for the sleeves to slip, which makes the stability poor.

[0004] In addition to the telescopic rod form, existing patent documents also disclose the folding rod form. For example, the Chinese patent with the authorization announcement number CN 205751455 U discloses a connecting mechanism for a folding flagpole, including a left connector and a right connector. The inner wall of one end of the left connector is provided with a sliding groove, and the other end of the sliding connector is provided with an external thread; the inner wall of the right connector is provided with an internal thread that matches the external thread, and the sliding connector and the right connector are connected by elastic ribs. This solution connects multiple sections of poles into an integral flagpole through a connecting mechanism. However, this solution does not describe how to connect the connecting mechanism to the poles. There is a problem with the poor stability of the connection between the connecting mechanism and the poles. It is easy for the connecting mechanism to loosen or disconnect at the connection position between the connecting mechanism and the poles, causing the poles to slip, affecting their use.

[0005] In addition, Chinese patent application CN 201502214 U discloses a tent pole and mosquito net pole assembly structure, which primarily includes a connecting sleeve, an elastic cord fixing structure, a tail sleeve, and tent poles or mosquito net poles. The connecting sleeve is installed between the tent poles or mosquito net poles, and the tail sleeve is fixedly connected to the ends of the tent poles or mosquito net poles at both ends of the tent pole and mosquito net pole assembly. The elastic cord fixing structure is installed within the connecting sleeve at both ends of the tent pole and mosquito net pole assembly. This solution only uses the connecting sleeve to secure the two mosquito net pole sections by interference fit, resulting in poor stability. When subjected to radial loads, the connecting sleeve and the mosquito net poles may wobble or even break, affecting normal use. Summary of the Invention

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a round bamboo flagpole and a method for manufacturing the round bamboo pole thereof, so as to solve the problems existing in the prior art. By using a connecting piece to connect the round bamboo poles, the male head of the connecting piece is provided with an extended section and penetrated into the female head, which can increase the depth of the male head penetrating into the round bamboo pole. Therefore, when connecting two round bamboo poles, the connecting piece can be used to improve the bending resistance of the round bamboo pole connection position, and when subjected to bending moment, the cracking of the end of the round bamboo pole is effectively avoided, thereby improving the connection stability of the round bamboo pole and ensuring the connection strength.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 4As shown, the present invention provides a round bamboo flagpole, comprising a plurality of round bamboo poles 1 and connectors for connecting the round bamboo poles 1. The round bamboo poles 1 are made of natural bamboo material. Each section of the round bamboo pole 1 may include one or more bamboo nodes 11. According to the length requirements of the round bamboo flagpole, multiple round bamboo poles 1 may be used for connection. The length of each round bamboo pole 1 may also be designed according to the convenience of use. Adjacent round bamboo poles 1 are connected by connectors, wherein the round bamboo pole 1 at one end is used to hang a flag 6, and the other end is used for hand-held or clamped. The connector comprises a male head 2 and a female head 3, and the male head 2 is threadedly connected to the female head 3. The male head 2 and the female head 3 are respectively installed at the ends of the round bamboo poles 1 for mutual connection, that is, the two ends of each section of the round bamboo pole 1 may be respectively provided with a male head 2 and a female head 3 for sequential connection. Of course, since the round bamboo pole 1 at the end is not used for further extension in the length direction, it is not necessary to connect to other round bamboo poles 1, and the male head 2 or the female head 3 may not be installed. The female head 3 is installed on the inner diameter side of a round bamboo pole 1 and can be connected by gluing. The male head 2 includes a fixed section 21, an extension section 22 and a threaded section 23 arranged in sequence, wherein the fixed section 21 is installed on the inner diameter side of another round bamboo pole 1, and the male head 2 and the inner diameter side of the round bamboo pole 1 can be directly bonded or bonded through the lining 4. The extension section 22 and the threaded section 23 are used to penetrate into the inner diameter side of a round bamboo pole 1 on which the female head 3 is installed. Specifically, there is a gap between the outer diameter of the extension section 22 and the inner diameter of the female head 3, and the threaded section 23 can be penetrated into the interior of the female head 3, and then the threaded section 23 is used to be threadedly connected to the female head 3, that is, a structure in which a round bamboo pole 1 and another round bamboo pole 1 are connected by the male head 2 and the female head 3 of the connector is formed. The present invention connects the round bamboo poles 1 by using a connecting piece, and the male head 2 and the female head 3 are respectively installed on the two round bamboo poles 1 that need to be connected. The male head 2 of the connecting piece is provided with an extended section 22 and penetrates into the female head 3, which can increase the depth of the male head 2 penetrating into the round bamboo pole 1. Therefore, when connecting the two round bamboo poles 1, the connecting piece can be used to improve the bending resistance of the connecting position of the round bamboo poles 1, and when subjected to bending moment, the cracking of the end of the round bamboo pole 1 is effectively avoided, thereby improving the connection stability of the round bamboo pole 1 and ensuring the connection strength.

[0036] Combine Figure 3 and Figure 4 As shown, the outer diameter side of the female head 3 is bonded to the inner diameter side of a round bamboo rod 1. Environmentally friendly structural adhesive can be used for bonding. An internal thread 31 is provided at one end near the interior of the round bamboo rod 1. The internal thread 31 can be matched with the external thread at the threaded section 23 to connect the male head 2 and the female head 3. The arrangement of the female head 3 within the round bamboo rod 1 not only facilitates the connection with the male head 2, but also avoids the problem of poor structural stability caused by directly machining threads on the inner diameter side of the round bamboo rod 1. On the other hand, the female head 3 can also form a reinforcement structure of the round bamboo rod 1, thereby enhancing the strength of the round bamboo rod 1 at this position and further reducing the risk of cracking at the end of the round bamboo rod 1.

[0037] The outer diameter of the fixing section 21 can also be provided with an inner lining 4. This inner lining 4 is cylindrical and may be provided with a base. The outer diameter of the inner lining 4 is bonded to the inner diameter of the other round bamboo pole 1. Thus, the inner lining 4 can perform a similar function to the female connector 3, effectively securing the male connector 2 while also increasing the strength of the end of the round bamboo pole 1 and reducing the risk of cracking. In practice, the inner lining 4 can be integrally manufactured with the male connector 2, bonded using an environmentally friendly structural adhesive.

[0038] like Figure 4 As shown, after the male head 2 and the female head 3 are connected, the end face of the lining 4 fits with the end face of the female head 3, and the end face of one round bamboo pole 1 fits with the end face of another round bamboo pole 1. By setting the lining 4 and the female head 3, the original fitting area of ​​the round bamboo pole 1 can be increased. When the round bamboo flagpole is subjected to bending moment, the end faces that fit together can be used to form a limiting structure, thereby improving the ability to resist bending moment and further ensuring the stability of the connection of the round bamboo pole 1. At the same time, the round bamboo pole 1 fits with the round bamboo pole 1 and the connecting parts fit with the connecting parts, which can also avoid the problem of uneven force caused by the abutment of different materials, and further improve the stability of the connection of the round bamboo pole 1.

[0039] like Figures 2-4 As shown, an elastic cord 5 can be included. The elastic cord 5 has a certain elasticity and can be retracted into the inner cavity of the male head 2 and the female head 3 after the round bamboo pole 1 is assembled. After the round bamboo pole 1 is disassembled and folded, it can be extended, which is convenient for disassembly and placement. The two sections of round bamboo pole 1 are connected by the elastic cord 5 and are not easy to lose after disassembly. One end of the elastic cord 5 is inserted and fixed in the female head 3 of one round bamboo pole 1, and the other end of the elastic cord 5 is inserted and fixed in the male head 2 of the other round bamboo pole 1. The male head 2 is provided with a space for accommodating the elastic cord 5. The bottom of the male head 2 and the female head 3 can be provided with a base plate. By perforating the base plate, the elastic cord 5 is passed through the base plate, tied into a knot, and fixed with structural adhesive.

[0040] Furthermore, the round bamboo pole 1 can be made of moso bamboo, ciba, green bamboo, or golden jade bamboo. Each section of the round bamboo pole 1 includes one or more bamboo nodes 11. The female end 3, male end 2, and lining 4 can all be made of polyvinyl chloride plastic. The combination of natural bamboo and polyvinyl chloride plastic creates a fabricated flagpole that is lightweight, suitable for handheld use, and offers excellent stability and durability.

[0041] During assembly, the present invention inserts a section of round bamboo pole 1 inlaid with a male head 2 into another section of round bamboo pole 1 inlaid with a female head 3, and connects the external thread of the threaded section 23 with the internal thread 31 by rotation to form a port thread fixation. Since the female head 3 and the male head 2 are threadedly connected except for the threaded position, the remaining positions are clearance-fitted, so that the two sections of round bamboo poles 1 can be easily inserted and fixed. The present invention realizes the connection of two round bamboo poles 1 by the threaded connection of the male head 2 and the female head 3 of the connecting piece. After the male head 2 and the female head 3 are respectively provided at the two ends of the same round bamboo pole 1, the docking connection of multiple sections of round bamboo poles 1 can be realized. After the multiple sections of round bamboo poles 1 are connected, a detachable flagpole is formed, which is convenient for disassembly and assembly and easy to use. When the flagpole needs to be folded up, it is only necessary to loosen and pull out the connection between the two sections of round bamboo poles 1 to achieve folding and storage. It can be seen that the round bamboo flagpole of the present invention has the advantages of quick disassembly and easy folding. It can be conveniently and quickly assembled into a flagpole for team building and traveling teams. It is easy to store and can save carrying space. It solves the technical problems of the existing technology that the flagpole is difficult to fold and transport and has low durability, which is conducive to its further promotion.

[0042] In a specific embodiment, the round bamboo pole 1 is made of round bamboo with a diameter of 1 to 5 cm and a bamboo wall thickness of 2 to 8 mm; the length of the round bamboo pole 1 is 30 to 50 cm; the length of the threaded section 23 of the male head 2 is 1 to 5 cm, corresponding to the length of the internal thread 31 of the female head 3 of 1 to 5 cm; the rope diameter of the elastic cord 5 is 2 to 8 mm.

[0043] The present invention also provides a method for manufacturing a round bamboo pole 1, which can be used for the round bamboo flagpole described above, comprising the following steps:

[0044] S1, cutting the harvested round bamboo into round bamboo poles 1, and drying the round bamboo poles 1;

[0045] S2, coating the round bamboo pole 1 after the drying treatment in S1 with a wood wax oil composite protective coating;

[0046] S3. Naturally drying the round bamboo pole 1 coated with the wood wax oil composite protective coating in S2.

[0047] After the round bamboo pole 1 completes the above steps, the male head 2 or the female head 3 can be installed on the end of the round bamboo pole 1 , and the elastic rope 5 can also be connected between the male head 2 and the female head 3 .

[0048] Different round bamboo poles 1 can be connected by a connector to form a whole flagpole, and after the flag surface 6 is installed on the end, a handheld or clamped fixed flag such as a flag for a tour guide can be formed.

[0049] When the round bamboo poles 1 are dried in S1, they can be dried in an oven at a temperature of 50-110° C. for 8-60 hours. When the round bamboo poles 1 coated with the wood wax oil composite protective coating are naturally dried in S3, they can be dried under natural ventilation conditions for 2-14 days.

[0050] After the round bamboo pole 1 in S2 is dried, the wax layer on the surface of the round bamboo pole 1 can be evenly removed by using soft sanding. The mesh number of the sandpaper used can be 100-2000 mesh. After the surface of the round bamboo pole 1 is sanded, it is then painted. During the painting, the wood wax oil composite protective coating is stirred evenly and evenly applied to the surface of the round bamboo pole 1, and then wiped clean. After the first layer is naturally dried for 1-5 days, a protective coating is formed, and then a second coat is applied. The protective coating is applied 3-5 times in total.

[0051] The wood wax oil composite protective coating can include wood wax oil, 3-iodo-2-propynyl butylcarbamate (IPBC), and a UV absorber, with a mass ratio of 100:(0.1-1.0):(0.1-1.0). IPBC is an organic mildew inhibitor, a white powder containing 90%-99% active ingredient, and can be dissolved in methanol, ethanol, or isopropyl alcohol.

[0052] After undergoing protective processes such as drying and surface coating, the durability of the round bamboo flagpole assembled from the round bamboo pole 1 is further improved when used outdoors. In summary, the present invention utilizes renewable round bamboo poles 1 to produce a highly durable flagpole that can be quickly folded and disassembled. The raw materials have the advantages of being environmentally friendly, lightweight, high-strength, and beautiful. The round bamboo flagpole can be quickly disassembled and assembled, takes up little space, and is easy to store and carry. After assembly, it functions just like an ordinary flagpole and is easy to use. However, the protective treatment improves durability and extends its service life.

[0053] The specific effects that the wood wax oil composite protective coating provided by the present invention can achieve can be referred to the following test data:

[0054] Taking the untreated Masson pine as the control sample, the fungal infection values ​​for blue stain fungi and mixed fungi were both 4, indicating that the test experiment was effective.

[0055] The test results of the blank control bamboo mildew control efficacy index are as follows: the average control efficacy against blue stain fungi is 0%, and the average control efficacy against mixed fungi is 0%.

[0056] The test results of the efficacy of pure wood wax oil in preventing and controlling bamboo mildew are as follows: the average efficacy against blue stain fungi is 25.0%, and the average efficacy against mixed fungi is 25.0%.

[0057] The test results of the efficacy of IPBC / wood wax oil (wood wax oil composite protective coating, IPBC concentration is 0.5) applied to bamboo mildew prevention and control indicators are as follows: the average efficacy against blue stain fungi is 100.0%, and the average efficacy against mixed fungi is 96.5%.

[0058] 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.
