Description

Technical Field

[0001] This utility model relates to the field of aluminum tube connector technology, and more specifically, to a guide rail type aluminum tube connector. Background Technology

[0002] Aluminum pipe connectors are accessories used to connect aluminum pipes. They are usually made of aluminum alloy or other corrosion-resistant materials and are lightweight and durable. They securely connect aluminum pipes through threads, snaps, welding or crimping, ensuring the sealing and stability of the piping system. Aluminum pipe connectors are widely used in air conditioning and refrigeration systems, automotive oil lines, building drainage, industrial hydraulic lines and other fields. They can simplify the installation process and reduce the risk of leakage, and are an indispensable component in aluminum pipe systems.

[0003] Traditional aluminum tube connectors typically employ a single fixed structure, lacking precise positioning aids. During connection, the pipes are prone to shifting or tilting, resulting in incomplete fit between the pipe connection surfaces, uneven stress on the sealing ring, and the formation of micro-gaps. Over time, this can lead to media leakage, deformation or cracking of the connection points, and affect the overall structural stability. Furthermore, traditional aluminum tube connectors are only suitable for straight-line connections and cannot flexibly adjust angles, increasing installation complexity. If subsequent pipe routing adjustments are required, the connection components must be disassembled and replaced, leading to increased maintenance costs.

[0004] In summary, to achieve faster and more accurate aluminum tube installation, it is necessary to address the problems of traditional aluminum tube connectors, such as fixed and simple structures, lack of precise positioning aids, resulting in poor sealing, reduced connection strength, and poor adaptability. The goal should be to simplify aluminum tube installation, achieve higher precision in the connected aluminum tubes, and improve sealing performance. Utility Model Content

[0005] The guide rail type aluminum tube connector provided by this utility model aims to solve the following problems: traditional aluminum tube connectors have a fixed and simple structure and lack precise positioning auxiliary devices, resulting in poor sealing, reduced connection strength, and poor adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a guide rail type aluminum tube connector, including a tightening bolt, on which a fixed joint, a first sealing ring, and a slotted joint are fixedly connected from right to left. A movable pipe is rotatably connected in the slotted joint. A fixed clamp is movably connected to the outer side of the fixed joint away from the first sealing ring. A fixed frame is fixedly connected below the fixed clamp. A feeding component is fixedly connected to the fixed frame. A slide is connected to the output end of the feeding component. Two height adjustment components are symmetrically fixedly connected to both sides of the slide. A movable clamp is fixedly connected to the output end of the height adjustment component. Two guide rods are fixedly connected to both sides of the fixed frame. The guide rods and the slide are slidably connected.

[0007] In a preferred embodiment, the feeding assembly includes a stepper motor fixedly connected to a fixed frame, the output end of the stepper motor being fixedly connected to a threaded rod, the threaded rod being rotatably connected to the fixed frame, and the threaded rod and the slide being threadedly connected.

[0008] In a preferred embodiment, the height adjustment assembly includes a hydraulic cylinder fixedly connected to the carriage, with a hydraulic rod fixedly connected to the output end of the hydraulic cylinder, and the other end of the hydraulic rod fixedly connected to a movable clamp.

[0009] In a preferred embodiment, one end of the fixed clamp opening is fixedly connected to the fixed end of the first hydraulic clamp, and the other end of the fixed clamp opening is fixedly connected to the output end of the first hydraulic clamp. One end of the movable clamp opening is fixedly connected to the fixed end of the second hydraulic clamp, and the other end of the movable clamp opening is fixedly connected to the output end of the second hydraulic clamp.

[0010] In a preferred embodiment, a pressure sensor is fixedly connected to the inside of the fixing clamp, and the pressure sensor is electrically connected to the first hydraulic clamp.

[0011] In a preferred embodiment, an alignment sensor is fixedly connected to the movable clamp, and the alignment sensor is electrically connected to the hydraulic cylinder.

[0012] In a preferred embodiment, a second sealing ring is fixedly connected to the inner wall of the fixed joint at the end away from the first sealing ring, and a plurality of locking blocks are provided on the side of the second sealing ring away from the first sealing ring, and the locking blocks are fixedly connected to the fixed joint.

[0013] The beneficial effects of this utility model are as follows: This invention employs a sliding cooperation design between the guide rod and the slide, ensuring that the pipeline maintains a straight-line motion during advancement and does not experience displacement deviation due to lateral forces. This guiding structure not only improves the accuracy of installation but also makes the entire connection process more stable and reliable. It is particularly suitable for pipeline docking scenarios with long distances or high precision requirements. Furthermore, in conjunction with the alignment sensor and hydraulic adjustment components, the position can be finely adjusted in real time to ensure that the two pipelines are perfectly coaxially aligned.

[0014] This invention utilizes a rotatable design for the slotted joint and movable pipe, allowing the connected pipe to freely adjust its angle within a certain range. It can adapt to different pipeline layouts without additional accessories. This flexibility is particularly suitable for situations where space is limited or where frequent adjustments to the pipeline route are required. It also significantly reduces the reliance on additional elbows, adapters, or adjustment brackets. This not only reduces material procurement and inventory costs but also simplifies the installation process and shortens construction time. At the same time, reducing connection points also means reducing the risk of leakage and improving the overall reliability of the entire pipeline system. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5 The guide rail type aluminum tube connector includes a tightening bolt 4. From right to left, a fixed joint 1, a first sealing ring 2, and a slotted joint 3 are fixedly connected to the tightening bolt 4. A movable pipe 5 is rotatably connected to the slotted joint 3. A fixed clamp 7 is movably connected to the outer side of the fixed joint 1 away from the first sealing ring 2. A fixed frame 6 is fixedly connected below the fixed clamp 7. A feeding component is fixedly connected to the fixed frame 6. A slide 12 is connected to the output end of the feeding component. Two height adjustment components are symmetrically fixedly connected to both sides of the slide 12. A movable clamp 14 is fixedly connected to the output end of the height adjustment component. Two guide rods 10 are fixedly connected to both sides of the fixed frame 6. The guide rods 10 and the slide 12 are slidably connected.

[0023] It should be noted that the movable pipe 5 fits tightly inside the fixed joint 1 and the slotted joint 3, ensuring good sealing of the connection device. The opening of the slotted joint 3 is larger than the opening of the movable pipe 5, allowing the movable pipe 5 to rotate freely on the slotted joint 3. The slide 12 has two smooth through holes on both sides. The size of the two through holes is adapted to the guide rod 10 to limit the movement of the slide 12 and prevent the slide 12 from having displacement deviation.

[0024] Refer to the instruction manual appendix Figure 4 The feeding assembly includes a stepper motor 1101 fixedly connected to the fixed frame 6. The output end of the stepper motor 1101 is fixedly connected to a threaded rod 1102. The threaded rod 1102 is rotatably connected to the fixed frame 6 and is threadedly connected to the slide 12.

[0025] It should be noted that the stepper motor 1101 is mounted on the fixed frame 6 and drives the threaded rod 1102 to rotate. The slide 12 has a threaded hole in the center, and the size of the threaded hole is adapted to the size of the threaded rod 1102.

[0026] Refer to the instruction manual appendix Figure 5 The height adjustment assembly includes a hydraulic cylinder 1301 fixedly connected to the slide 12, a hydraulic rod 1302 fixedly connected to the output end of the hydraulic cylinder 1301, and the other end of the hydraulic rod 1302 fixedly connected to the movable clamp 14.

[0027] It should be noted that the hydraulic cylinder 1301 is mounted on the slide 12 and moves together with the slide 12, while driving the hydraulic rod 1302 to move linearly, thereby realizing the height change of the movable clamp 14.

[0028] Refer to the instruction manual appendix Figures 4 to 5 One end of the opening of the fixed clamp 7 is fixedly connected to the fixed end of the first hydraulic clamp 9, and the other end of the opening of the fixed clamp 7 is fixedly connected to the output end of the first hydraulic clamp 9. One end of the opening of the movable clamp 14 is fixedly connected to the fixed end of the second hydraulic clamp 15, and the other end of the opening of the movable clamp 14 is fixedly connected to the output end of the second hydraulic clamp 15.

[0029] It should be noted that the first hydraulic clamp 9 is installed between the openings of the fixed clamp 7 to control the clamping degree of the fixed clamp 7, and the second hydraulic clamp 15 is installed between the movable clamps 14 to control the clamping degree of the movable clamps 14.

[0030] Refer to the instruction manual appendix Figure 4 A pressure sensor 8 is fixedly connected to the inside of the fixing clamp 7, and the pressure sensor 8 is electrically connected to the first hydraulic clamp 9.

[0031] It should be noted that the pressure sensor 8 is in direct contact with the outer wall of the fixed joint 1 and is subjected to compressive force, resulting in deformation. The pressure sensor 8 converts the mechanical deformation into an electrical signal for analysis and processing, and then calculates the optimal clamping force to control the first hydraulic clamp 9 to work. The model of the pressure sensor 8 in this device is CYYZ11.

[0032] Refer to the instruction manual appendix Figure 5 A centering sensor 16 is fixedly connected to the movable clamp 14, and the centering sensor 16 is electrically connected to the hydraulic cylinder 1301.

[0033] It should be noted that the centering sensor 16 uses a laser or infrared beam to illuminate the fixed joint 1, and detects the offset by receiving changes in reflected or transmitted light. Then, it calculates and analyzes the offset, converts the analysis results into a control signal, and controls the hydraulic cylinder 1301 to work. The model of the centering sensor 16 in this device is KEYENCE IL-100.

[0034] Refer to the instruction manual appendix Figures 1 to 2 A second sealing ring 17 is fixedly connected to the inner wall of the fixed connector 1 at the end away from the first sealing ring 2. A plurality of locking blocks 18 are provided on the side of the second sealing ring 17 away from the first sealing ring 2. The locking blocks 18 are fixedly connected to the fixed connector 1.

[0035] It should be noted that the locking blocks 18 are made of elastic material, and there are gaps between the locking blocks 18 to increase friction and automatically compensate when the pipe expands.

[0036] Working principle: The fixed clamp 7 is installed on the fixed joint 1 and roughly fixed by the first hydraulic clamp 9. The aluminum tube to be connected is installed on the movable clamp 14, with the end of the aluminum tube near the fixed clamp 7 slightly longer than the movable clamp 14. Then, the second hydraulic clamp 15 clamps the aluminum tube, causing the stepper motor 1101 to output power to the threaded rod 1102, causing the threaded rod 1102 to rotate. This drives the slide 12 threaded to the threaded rod 1102 to move linearly. At the same time, the centering sensor 16 on the movable clamp 14 emits an infrared beam to illuminate the fixed joint 1, and receives the reflected or transmitted light. The offset is detected by the change in pressure, and then the offset is calculated and analyzed. The analysis result is converted into a control signal to control the hydraulic cylinder 1301 to work, so that the hydraulic cylinder 1301 outputs pressure to the hydraulic rod 1302, pushing the hydraulic rod 1302 to move linearly until the aluminum tube and the fixed joint 1 are aligned. After the aluminum tube is pushed into the fixed joint 1, the first hydraulic clamp 9 continues to clamp, and the pressure sensor 8 performs real-time measurement until the aluminum tube and the fixed joint 1 are completely sealed. The second sealing ring 17 and the locking block 18 are used to ensure the sealing and stability of the connection. At the same time, the connection direction of the aluminum tube can be changed arbitrarily by rotating the movable pipe 5.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
