[0001] This utility model relates to the field of connector technology, specifically to aluminum alloy connectors with good stability. Background Technology

[0002] In the existing industrial manufacturing and engineering technology fields, aluminum alloy connectors have become a crucial component due to their excellent properties such as light weight, high strength, and corrosion resistance. They are widely used in the connection and fixing of various pipeline systems. Whether in the petrochemical, aerospace, automobile manufacturing, or shipbuilding industries, aluminum alloy connectors occupy an indispensable position.

[0003] In the current technology, most aluminum alloy connectors commonly found on the market adopt a fixed diameter design. This design undoubtedly demonstrates excellent performance and provides a stable and reliable connection when connecting pipes of the same specification. However, in actual use, the needs of different engineering practices are complex and diverse. In particular, when facing pipe systems of different sizes and diameters, this fixed diameter connector cannot achieve a perfect match with the pipe, resulting in problems such as gaps and misalignments between the connector and the pipe. Moreover, this insufficient restriction on the pipe leads to instability in the connection after pipe installation, which can ultimately damage the pipe system. Utility Model Content

The anti-slip pad body is aligned and clamped with the pipeline through contact, and the second fastening bolt is used to limit and fix the connecting plate.

[0007] In a preferred embodiment of this technical solution, a storage groove is provided on the connecting rack, and the connecting plate is installed on the storage groove.

[0008] In a preferred embodiment of this technical solution, the outer casing assembly includes a connecting bracket fixedly mounted on the adjusting component, a connecting block fixedly connected to the connecting bracket, a first connecting outer casing fixedly connected to the connecting block, a second connecting outer casing disposed on the first connecting outer casing, a connecting seat fixedly connected to the second connecting outer casing, a third fastening bolt disposed between the second connecting outer casing and the first connecting outer casing, and a fastening nut threadedly connected to the third fastening bolt. The connecting block is snapped into the connecting seat. A rotating gear ring is rotatably connected to the first connecting outer casing and the second connecting outer casing. A first gear and a second gear are rotatably connected to the first connecting outer casing and the second connecting outer casing. A connecting rack is slidably connected to the first connecting outer casing and the second connecting outer casing. The connecting block and the connecting seat are used to align and limit the connection between the first connecting outer casing and the second connecting outer casing. The connection between the second connecting outer casing and the first connecting outer casing is fastened by the cooperation of the third fastening bolt and the fastening nut.

[0009] In the preferred embodiment of this technical solution, both the first connecting shell and the second connecting shell have a limiting groove at the relative position of the rotating gear ring, and the rotating gear ring is rotatably connected to the groove.

[0010] In a preferred embodiment of this technical solution, the second connecting housing and the first connecting housing have a limiting groove at the relative position of the sliding rod, and the sliding rod is slidably connected to the groove.

[0011] According to the preferred embodiment of this technical solution, the adjustment component includes a fixed seat fixedly mounted on the mounting base, a second worm gear rotatably connected to the fixed seat, a second knob fixedly connected to the second worm gear, a second worm wheel meshing with the second worm gear, a connecting shaft fixedly connected to the second worm wheel, and a rotating seat fixedly connected to the connecting shaft. The connecting shaft is rotatably connected to the fixed seat, and the connecting bracket is fixedly mounted on the rotating seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the first knob, the sliding rod slides in the through groove of the outer shell component through the transmission of the corresponding components, thereby driving the clamping component to adjust its position. This multi-stage gear and worm gear transmission, through the self-locking property of the first worm and the first worm wheel, ensures a stable clamping force on the pipeline while allowing the position of the sliding rod and the clamping component to change flexibly. It can adapt to pipelines of different sizes and diameters, avoiding gap and misalignment problems caused by the mismatch between the fixed diameter connector and the pipeline.

[0015] 2. By adjusting the components, the angle and position of the outer shell assembly and its connected parts can be flexibly adjusted to ensure that the clamping assembly can contact the pipeline at the optimal angle, avoiding connection deviations caused by unsuitable angles. While meeting the diverse installation needs in complex projects, the worm gear transmission has a self-locking characteristic. After adjustment, the outer shell assembly can stably maintain the adjusted angle and will not change the angle on its own due to external forces, ensuring the stability of the clamping assembly's restriction on the pipeline and further guaranteeing the firmness of the pipeline connection.

[0016] 3. When dealing with pipes of different specifications and shapes, the connecting plate can be easily disassembled and replaced with a suitable model, allowing the connector to flexibly meet diverse pipe clamping needs. This avoids the problem of being unable to adapt to special pipes due to the fixed and non-replaceable clamping components, further expanding the scope of application of the connector. From the perspective of maintenance and replacement, if the anti-slip pad body is worn or aged, or the connecting plate is damaged, it can be replaced or repaired separately without replacing the entire sliding rod or even the entire connector.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7This utility model provides an embodiment of a stable aluminum alloy connector, including a mounting base 1, a first fastening bolt 4 mounted on the mounting base 1, an adjustment assembly mounted on the mounting base 1, a housing assembly mounted on the adjustment assembly, a first worm gear 21 rotatably connected to the housing assembly, a first knob 22 fixedly connected to one end of the first worm gear 21, a first worm wheel 23 meshing with the first knob 22, a first gear 24 fixedly connected to the first worm wheel 23, a rotating gear ring 25 meshing with the first gear 24, a second gear 26 meshing with the rotating gear ring 25, a third gear 27 fixedly connected to the second gear 26, a sliding rod 28 slidably connected to the housing assembly, a connecting rack 29 fixedly connected to the sliding rod 28, and a clamping assembly mounted on the sliding rod 28. The third gear 27 meshes with the connecting rack 29, and the second gear 26 is rotatably connected to the first gear 24 on the housing assembly. The first knob 22 is used to adjust the first worm gear 21. The rotation and adjustment component is used to adjust the angle of the outer shell assembly and its connected components. It restricts the pipe by contacting it with the clamping component. During installation, the first fastening bolt 4 is passed through the mounting base 1 and connected to the external wall to achieve overall fixed installation of the connector. Then, according to the actual use requirements, the angle of the entire outer shell assembly and connected components can be adjusted by the adjustment component. When clamping the pipe, rotating the first knob 22 causes the first worm 21 to rotate. The first worm 21 meshes with the first worm wheel 23 and drives it to rotate. The first gear 24 on the first worm wheel 23 rotates accordingly and meshes with the rotating gear ring 25, causing the rotating gear ring 25 to rotate in the rotating groove of the first connecting outer shell 213 and the second connecting outer shell 215. The rotating gear ring 25 then meshes with the second gear 26, driving the second gear 26 and the coaxial third gear 27 to rotate. The third gear 27 meshes with the connecting rack 29, thereby pushing the sliding rod 28 to slide in the through groove of the outer shell assembly. While adjusting the position of the clamping component, the pipe is clamped and installed.

[0027] Please see Figure 1-6 A further solution based on this embodiment is as follows: The clamping assembly includes a connecting plate 210 mounted on one end of the sliding rod 28, an anti-slip pad body 211 disposed on the connecting plate 210, and a second fastening bolt 212 threadedly connected to the sliding rod 28. The anti-slip pad body 211 contacts and aligns with the pipeline for clamping. The second fastening bolt 212 is used to limit and fix the connecting plate 210. The anti-slip pad body 211 can increase the friction between the anti-slip pad body and the pipeline, effectively preventing the pipeline from sliding during clamping and improving the stability of clamping. The cooperation between the connecting plate 210 and the second fastening bolt 212 allows the clamping assembly to be disassembled and replaced according to actual needs, increasing the versatility of the assembly.

[0028] Please see Figure 6A further solution based on this embodiment is as follows: a storage groove is provided on the connecting rack 29, and the connecting plate 210 is installed on the storage groove. The design of the storage groove provides a dedicated installation space for the connecting plate 210, which plays a certain limiting role for the connecting plate 210, preventing it from shifting laterally during operation, ensuring accurate alignment when the clamping component contacts the pipe, and further improving the stability of the connection.

[0029] Please see Figure 1-3 A further embodiment of this solution is as follows: the outer casing assembly includes a connecting bracket 214 fixedly mounted on the adjusting assembly, a connecting block 216 fixedly connected to the connecting bracket 214, a first connecting outer casing 213 fixedly connected to the connecting block 216, a second connecting outer casing 215 disposed on the first connecting outer casing 213, a connecting seat 217 fixedly connected to the second connecting outer casing 215, a third fastening bolt 218 disposed between the second connecting outer casing 215 and the first connecting outer casing 213, and a fastening nut 219 threadedly connected to the third fastening bolt 218. The connecting block 216 is engaged with the connecting seat 217. A rotating gear ring 25 is rotatably connected to the first connecting outer casing 213 and the second connecting outer casing 215. A first gear 24 and a second gear 26 are rotatably connected to the first connecting outer casing 213 and the second connecting outer casing 215. 5. The connecting rack 29 is slidably connected to the first connecting housing 213 and the second connecting housing 215. The connecting block 216 and the connecting seat 217 are used to align and limit the connection between the first connecting housing 213 and the second connecting housing 215. The connection between the second connecting housing 215 and the first connecting housing 213 is fastened by the cooperation of the third fastening bolt 218 and the fastening nut 219. The snap-fit ​​cooperation of the connecting block 216 and the connecting seat 217 can position the installation of the first connecting housing 213 and the second connecting housing 215. The fastening effect of the third fastening bolt 218 and the fastening nut 219 ensures the tightness of the connection between the two housings and avoids loosening during use. At the same time, the housing structure provides a stable installation space and protection for the internal gears, gear rings and other transmission components, reducing the interference of the external environment on the transmission components.

[0030] Please see Figure 1-4 A further solution based on this embodiment is as follows: both the first connecting shell 213 and the second connecting shell 215 have limiting grooves at the relative positions of the rotating toothed ring 25. The rotating toothed ring 25 is rotatably connected to the grooves. The grooves limit the rotation of the rotating toothed ring 25, ensuring that the rotating toothed ring 25 can only rotate within a fixed trajectory, thus avoiding deviation or shaking during rotation.

[0031] Please see Figure 1-4A further solution based on this embodiment is as follows: the second connecting shell 215 and the first connecting shell 213 have a limiting groove at the relative position of the sliding rod 28. The sliding rod 28 is slidably connected to the groove. The groove provides a guiding function for the sliding of the sliding rod 28, ensuring that the sliding rod 28 can only move in a straight line along the direction of the groove, thus ensuring the accuracy of the clamping assembly adjustment. The groove provides support and limiting function for the sliding rod 28, preventing the sliding rod 28 from bending or deviating during movement, improving the stability of the sliding rod 28's operation, and thus ensuring the normal operation of the clamping assembly.

[0032] Please see Figure 1 , Figure 7 A further embodiment of this solution is as follows: the adjustment assembly includes a fixed base 31 fixedly mounted on the mounting base 1, a second worm gear 32 rotatably connected to the fixed base 31, a second knob 33 fixedly connected to the second worm gear 32, a second worm wheel 34 meshing with the second worm gear 32, a connecting shaft 35 fixedly connected to the second worm wheel 34, and a rotating seat 36 fixedly connected to the connecting shaft 35. The connecting shaft 35 is rotatably connected to the fixed base 31, and the connecting bracket 214 is fixedly mounted on the rotating seat 36. The second knob 33 is used to adjust the rotation of the second worm gear 32, and the rotation of the connecting shaft 35 drives the rotating seat 36 and the connected housing assembly to rotate. The worm gear transmission method has a self-locking function, which can keep the adjusted angle stable and will not change on its own due to external forces. The angle can be adjusted by rotating the second knob 33, which improves the applicability of the connector under different installation angle requirements.

[0033] Please see Figure 7 A further solution based on this embodiment is as follows: the fixed seat 31 has a limiting groove at the relative position of the connecting shaft 35. The connecting shaft 35 is rotatably connected to the groove. The groove provides limiting and support for the connecting shaft 35, ensuring that the connecting shaft 35 can only rotate within the groove. This avoids axial or radial offset of the connecting shaft 35 during rotation, while reducing wear between the connecting shaft 35 and the fixed seat 31, ensuring the smoothness and stability of the rotation of the connecting shaft 35, and thus ensuring the overall adjustment accuracy and service life of the adjustment assembly.

[0034] Working principle: During assembly, the connecting blocks 216 and connecting seats 217 connected to the first connecting shell 213 and the second connecting shell 215 are aligned and snapped together. The connection between the first connecting shell 213 and the second connecting shell 215 is limited by tightening the third fastening bolt 218 and the fastening nut 219. Then, according to the shape of the pipeline, the required connecting plate 210 and anti-slip pad body 211 are selected and installed into the storage groove of the sliding rod 28. The second fastening bolt 212 is provided for fixing and limiting.

[0035] During installation, the first fastening bolt 4 is passed through the mounting base 1 and connected to the external wall to achieve overall fixation of the connector. According to actual usage requirements, rotating the second knob 33 drives the second worm gear 32 to rotate. The second worm gear 32 meshes with the second worm wheel 34, causing the second worm wheel 34 to drive the connecting shaft 35 to rotate within the groove of the fixed seat 31. This, in turn, drives the connecting bracket 214 and the outer casing assembly to rotate via the rotating seat 36, achieving angle adjustment. When fixing the pipeline, rotating the first knob 22 causes the first worm gear 21 to rotate. The first worm gear 21 meshes with the first worm wheel 23, causing it to rotate. The first gear 24 on the worm gear 23 rotates and meshes with the rotating gear ring 25, causing the rotating gear ring 25 to rotate in the groove between the first connecting housing 213 and the second connecting housing 215. The rotating gear ring 25 then meshes with the second gear 26, driving the second gear 26 and the coaxial third gear 27 to rotate. The third gear 27 meshes with the connecting rack 29, thereby pushing the connecting rack 29 and the connected sliding rod 28 to slide in the through groove of the housing assembly. While adjusting the position of the connecting plate 210 and the anti-slip pad body 211, the anti-slip pad body 211 contacts the pipe to achieve clamping, thus completing the installation and fixing.
