Abstract
Description
A type of easy-to-connect aluminum alloy flange Technical Field
[0001] This utility model relates to the field of flange connection technology, specifically to an aluminum alloy flange that is easy to connect. Background Technology
[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, attached to the pipe ends. Flanges have holes, and bolts are used to tighten two flanges together. A gasket is used for sealing between flanges. A flange is a disc-shaped component, most commonly found in piping engineering, and flanges are always used in pairs. In piping engineering, flanges are mainly used for connecting pipes. Aluminum alloy flanges, as important components for connecting pipes, valves, and other equipment, play a crucial role in industrial production.
[0003] According to patent document CN222209380U, this utility model relates to the field of aluminum alloy flange technology, specifically disclosing a conveniently connected aluminum alloy flange, including a main plate and a secondary plate. Pipes are connected to the middle of the main plate and the secondary plate on opposite sides. A positioning protrusion is symmetrically fixed on the side of the main plate facing the secondary plate, and a corresponding positioning groove is provided on the secondary plate. The combined effect of the connecting protrusion and the positioning groove makes the flange connection more convenient, solving the problem of inconvenient positioning due to the large number and small diameter of positioning pins in traditional solutions, thus improving the ease of flange connection. Simultaneously, when the plates gradually loosen due to vibration, the storage box experiences a force greater than its own strength, causing it to be crushed and the colored liquid inside to flow out, thus alerting personnel.
[0004] The existing aluminum alloy flange installation process is relatively complex and often requires the use of a large number of locating pins for fixing.

The drive assembly 12 includes an anti-slip turntable 121. The top of the anti-slip turntable 121 is movably connected to the bottom of the annular main disk shell 111. The inner wall of the anti-slip turntable 121 is movably connected to the outer wall of the fixed disk 112. A connecting ring 122 is fixedly connected to the top of the anti-slip turntable 121. The outer wall of the connecting ring 122 is movably connected to the inner wall of the annular through-hole 115. A toothed ring 123 is fixedly connected to the top of the connecting ring 122. The bottom of the toothed ring 123 is movably connected to the inner wall of the annular main disk shell 111. The clamping assembly 13 includes a fixing plate 131. The bottom of the fixing plate 131 is fixedly connected to the inner wall of the annular main disk shell 111. The fixed plate 131 has two fixed support sleeves 132 on its top front and rear sides. A connecting shaft 133 is movably connected to the inner wall of the first support sleeve 132. A worm gear 134 is fixedly connected to the end of the two connecting shafts 133 that are close to each other. The fixed plate 131 has two fixed support sleeves 135 on its top left and right sides. A limiting plate 136 is movably connected to the inner wall of the second support sleeve 135. A gear 137 is fixedly connected to the end of the two limiting plates 136 that are far apart from each other.

The connecting structure 2 includes a secondary disc 21, the bottom of which has a ring array of multiple circular through holes 22 extending to the top.The bottom of the auxiliary disk 21 has L-shaped slots 23 on all four sides (front, back, left, and right). The inner wall of the L-shaped slot 23 is movably connected to the outer wall of the L-shaped locking block 1303. By rotating the anti-slip turntable 121, the connecting ring 122 rotates on the inner wall of the annular through hole 115, which in turn drives the gear ring 123 to rotate. The rotation of the gear ring 123 drives the gear two 1300 to rotate, causing the front connecting shaft 133 to rotate, which in turn drives the worm gear 134 and the rear connecting shaft 133 to rotate. The rotation of the worm gear 134 drives the worm wheel 138 to rotate, which in turn drives the two limiting disks 136 to drive the gear one 137 to rotate. The gear one 137 then... The rotation of the gear 130 causes the movable plate 139 to slide along the inner wall of the guide plate 1301 in the guide hole 116. Simultaneously, the connecting plate 1302 causes the L-shaped locking block 1303 to slide on the top of the annular main disc shell 111 until the L-shaped locking block 1303 engages with the L-shaped slot 23, thus fixing the secondary disc 21. The engagement of the L-shaped locking block 1303 with the L-shaped slot 23 facilitates quick flange connection, simplifying operation, improving work efficiency and practicality, and increasing the stability of the flange connection. The self-locking property of the worm gear 134 and worm wheel 138 prevents the L-shaped locking block 1303 from disengaging from the L-shaped slot 23, thus improving the robustness of the flange connection.
[0031] Please refer to Figures 8-9. Both stress dispersion structures 3 include a fixing ring 31. Multiple reinforcing ribs 32 are fixedly connected to the outer wall of the fixing ring 31 in an annular array. The bottom of one fixing ring 31 and reinforcing rib 32 is fixedly connected to the bottom of the fixing disk 112, and the bottom of the other fixing ring 31 and reinforcing rib 32 is fixedly connected to the top of the auxiliary disk 21. The sealing structure 4 includes an annular rubber pad 41. Multiple circular through holes 43 extending to the bottom are arranged in an annular array on the top of the annular rubber pad 41. Rectangular through holes 42 extending to the bottom are opened on the front, back, left, and right sides of the top of the annular rubber pad 41. The inner wall of the rectangular through holes 42 is movably connected to the outer wall of the connecting plate 1302. The annular rubber pad 4... The top of the flange 1 is fixedly connected to the bottom of the auxiliary plate 21, and the bottom of the annular rubber gasket 41 is movably connected to the top of the annular main plate shell 111. Through the fixing ring 31 and the reinforcing rib 32, the stress generated by pressure and vibration at the connection of the pipe 5 can be effectively dispersed, which enhances the overall structural strength of the flange, avoids loosening during use, and extends the service life. At the same time, the sealing performance of the flange is further enhanced by the annular rubber gasket 41. The circular through hole 43 and the rectangular through hole 42 opened in the annular rubber gasket 41 facilitate the passage of the fixing structure 1 and other structures. The tight fit between the annular rubber gasket 41 and the fixing structure 1 and the connecting structure 2 effectively prevents the leakage of the medium.
[0032] Working principle:
[0033] Rotating the anti-slip turntable 121 causes the connecting ring 122 to rotate within the annular through hole 115, which in turn drives the gear ring 123 to rotate. The rotation of the gear ring 123 drives the second gear 1300 to rotate, causing the front connecting shaft 133 to rotate, which in turn drives the worm gear 134 and the rear connecting shaft 133 to rotate. The rotation of the worm gear 134 drives the worm wheel 138 to rotate, which in turn drives the two limiting discs 136 to drive the first gear 137 to rotate. The rotation of the first gear 137 drives the teeth 130, which in turn drives the movable plate 139 to drive the guide plate 1301. The inner wall of the guide hole 116 slides, while the connecting plate 1302 drives the L-shaped locking block 1303 to slide on the top of the annular main disc shell 111 until the L-shaped locking block 1303 is engaged in the interior of the L-shaped slot 23, thereby fixing the sub-disc 21. The engagement between the L-shaped locking block 1303 and the L-shaped slot 23 facilitates quick connection of the flange, making the operation simple and convenient, improving work efficiency and practicality, and increasing the stability of the flange connection. The self-locking property of the worm 134 and worm wheel 138 prevents the L-shaped locking block 1303 from disengaging from the L-shaped slot 23, thus improving the firmness of the flange connection.
[0034] The fixing ring 31 and reinforcing rib 32 effectively disperse the stress generated by pressure and vibration at the connection of the pipe 5, enhance the overall structural strength of the flange, prevent loosening during use, and extend service life. At the same time, the annular rubber gasket 41 further enhances the sealing performance of the flange. The circular through hole 43 and rectangular through hole 42 opened in the annular rubber gasket 41 facilitate the passage of the fixing structure 1 and other structures. The tight fit between the annular rubber gasket 41 and the fixing structure 1 and the connecting structure 2 effectively prevents the leakage of the medium.
