Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure gas ribs, and in particular relates to a high-pressure gas rib cylindrical column foot head. Background Art

[0002] A high-pressure gas rib is a tubular structure that can be filled with high-pressure gas to form a sturdy, load-bearing component. It is often used as the skeleton of a high-pressure inflatable tent. With the continuous development of high-pressure inflatable tent technology and applications, the application of high-pressure gas ribs is gradually no longer limited to the high-pressure inflatable tent field but is expanding to a wider range of spaces. After being filled with high-pressure gas, the high-pressure gas rib can be used as a structural member to construct a structure. The ends of the rods need to have a variety of connectivity, and the form of the gas rib end is mainly determined by the column foot head. At the same time, the load-bearing capacity of the high-pressure gas rib mainly depends on the material and airtightness of the high-pressure gas rib. The head of the gas rib column foot plays a key role in the airtightness of the high-pressure gas rib. Therefore, the form of the gas rib column foot head not only affects the practicality of the high-pressure gas rib but also determines its airtightness. Solving the diversity and airtightness of the high-pressure gas rib column foot can greatly improve the practicality of the high-pressure gas rib. The end of a tubular rod structure made of other materials (such as metal, resin, etc.) is generally cylindrical, on which connectors of other structural forms can be assembled or welded, thereby achieving diversified connection of the rods. Therefore, it is very necessary to design a column foot head for a high-pressure gas rib, which forms a cylindrical structure while ensuring airtightness and structural strength, to achieve diversified application of the high-pressure gas rib and improve its practicality.

[0003] The traditional high-pressure gas rib column foot head design has some shortcomings, which are mainly manifested in the following two aspects:

[0004] 1. Insufficient sealing performance: Traditional heads mostly use simple metal sealing methods. Although they can meet the sealing requirements to a certain extent, they are prone to leakage under high-pressure environments. Especially after long-term use, due to aging or wear of the material, the sealing performance will gradually decline, affecting the use of high-pressure inflatable structures;

[0005] 2. Complex structure and inconvenient installation: The design of some high-pressure gas rib column foot heads is relatively complex, and the installation and maintenance process is cumbersome, requiring professional tools and technicians to operate, which increases costs and time consumption. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a high-pressure gas-rib cylindrical column foot head.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A high-pressure gas-ribbed cylindrical column foot seal comprises a woven tube, a retaining ring, a rubber gasket, a shaft seal, and an end cap. The woven tube is provided with an inner membrane, and the ends of the woven tube are provided with N tubular members. The retaining ring passes through the N tubular members in sequence. The shaft seal is mounted in conjunction with the tubular members on the woven tube, and the end cap is mounted on the outer end surface of the shaft seal. The rubber gasket is disposed within the woven tube, with one side of the rubber gasket in contact with the inner membrane and the other side in contact with the shaft seal.

[0009] Wherein, N is a positive integer greater than or equal to 1.

[0010] Preferably, the shaft seal is provided with N arc-shaped grooves for cooperating with the tubular member for installation.

[0011] Preferably, the length of the arc-shaped slot is greater than or equal to the length of the tubular member on the woven tube, and the width of the arc-shaped slot is greater than the thickness of the tubular member.

[0012] Preferably, the end cover is connected to the shaft seal via a locking screw.

[0013] Preferably, the fixing ring is an annular open structure so as to facilitate assembly with the woven tube.

[0014] Preferably, the rubber pad is made of soft material to avoid contact between the inner membrane and the shaft seal, thereby avoiding wear of the inner membrane and improving the airtightness of the head.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The design of the fixed ring passing through multiple tubular parts in sequence strengthens the connection strength between the braided tube and the shaft seal, and improves the stability and reliability of the entire head structure;

[0017] 2. The shaft seal is provided with N arc-shaped slots for cooperating with the tubular member. The length of the arc-shaped slot is greater than or equal to the length of the tubular member on the woven tube, and the width of the arc-shaped slot is greater than the thickness of the tubular member. Through the above structural design, the tubular member at the head of the woven tube can pass through the shaft seal, and the shaft seal can effectively clamp the fixing ring, thereby improving the stability and strength of the head structure;

[0018] 3. There are threaded holes on the cylindrical surface of the shaft seal and through holes on the annular surface of the end cover to facilitate the installation of locking screws. Their function is to protect the fabric tube, avoid its contact with the outside world, reduce the wear of the fabric tube, and thus improve the strength and service life of the head;

[0019] 4. The fixing ring has an annular opening structure so that it can be assembled with the woven tube;

[0020] 5. The rubber pad is made of soft material to avoid contact between the inner membrane and the shaft seal, thereby avoiding wear of the inner membrane and improving the airtightness of the head;

[0021] To sum up, the utility model enables high-pressure air ribs to be used as rod structures in more fields. At the same time, the design of the column foot head avoids perforation damage on the woven tube and the inner membrane, and effectively protects the woven tube and the inner membrane, reducing the loss caused by wear and tear, so that the air rib has higher pressure resistance, airtightness and service life.

[0031] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0032] Example 1:

[0033] like Figure 1-6 As shown, a high-pressure gas-rib cylindrical column foot head includes a woven tube 1, a fixing ring 3, a rubber gasket 4, a shaft seal 5, and an end cap 6. The woven tube 1 is provided with an inner membrane 2, and the end of the woven tube 1 is provided with N tubular members 9. The fixing ring 3 passes through the N tubular members 9 in sequence. The shaft seal 5 is installed in conjunction with the tubular members 9 on the woven tube 1, and the end cap 6 is installed on the outer end surface of the shaft seal 5. The rubber gasket 4 is provided in the woven tube 1, and one side of the rubber gasket 4 contacts the inner membrane 2, and the other side contacts the shaft seal 5.

[0034] Wherein, N is a positive integer greater than or equal to 1.

[0035] In this embodiment, the high-pressure gas rib cylindrical column foot cap is constructed in an assembled form without destroying the high-pressure gas rib stress-bearing structure (woven tube 1) and the air-sealing structure (inner membrane 2), thereby improving the strength of the high-pressure gas rib as a structural member and its adaptability to applications in other fields. The end of the woven tube 1 is evenly divided into 2N parts, where the value of N depends on the diameter of the gas rib and the stress-bearing strength of the structure. N of the parts are cut off, and the remaining N parts are sewn outwardly to the outside of the woven tube 1, forming a tubular member 9 at the head with a space slightly larger than the axial diameter of the fixing ring 3, so that the fixing ring 3 can pass through the middle of the tubular member 9 and be fixedly assembled with the woven tube 1.

[0036] Example 2:

[0037] A high pressure gas rib cylindrical column foot head, which is different from the embodiment 1 in that Figure 7 As shown, the shaft seal 5 is provided with N arc-shaped grooves 8 for cooperating with the tubular member 9 for installation. The length of the arc-shaped grooves 8 is greater than or equal to the length of the tubular member 9 on the woven tube 1, and the width of the arc-shaped grooves 8 is greater than the thickness of the tubular member 9. Through the above structural design, the tubular member 9 at the head of the woven tube 1 can pass through the shaft seal 5, and the shaft seal 5 can effectively clamp the fixing ring 3, thereby improving the stability and strength of the head structure.

[0038] Furthermore, the end cap 6 is connected to the shaft seal 5 via a locking screw 7. Specifically, a threaded hole is provided on the cylindrical surface of the shaft seal 5, and a through hole is provided on the annular surface of the end cap 6 to facilitate the installation of the locking screw 7. Its function is to protect the fabric tube 1 from contact with the outside world, reduce the wear of the fabric tube 1, and thus improve the strength and service life of the head.

[0039] like Figure 8 As shown, the fixing ring 3 is an annular open structure so as to facilitate assembly with the woven tube 1 .

[0040] Furthermore, the rubber pad 4 is made of a soft material, which prevents the inner membrane 2 from contacting the shaft seal 5, thereby preventing the wear of the inner membrane 2 and improving the airtightness of the head.

[0041] During the manufacture of the present invention, the woven tube 1 and the inner membrane 2 are fixed by an adhesive along the remaining length except for the end portion. The end portion of the inner membrane 2 is directly heat-sealed. The rubber pad 4 is installed in the end portion of the woven tube 1, with one side in contact with the inner membrane 2 and the other side in contact with the shaft seal 5. The N tubular members 9 at the head of the woven tube 1 pass through the N arc-shaped grooves 8 provided on the shaft seal 5, and then the fixing ring 3 passes through the N tubular members 9 at the head of the woven tube 1 in sequence. Finally, the shaft seal 5 and the end cover 6 are fixed by locking screws 7.
