[0011] The adapter structure B has a through hole B for the external thread portion of the pipe connector B to pass through. An anti-rotation groove is recessed on one side of the adapter structure B and outside the through hole B. The anti-rotation groove matches the outer peripheral contour shape of the mounting flange of the pipe connector B.

[0012] After the external thread portion of the pipe connector B passes through the through hole B, the mounting flange portion of the pipe connector B is embedded in the anti-rotation groove and abuts against the bottom surface of the anti-rotation groove. The external thread portion of the pipe connector B after passing through the through hole B is connected to a fastening nut B through the external thread B.

[0029] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail.

[0030] A pipeline enclosure structure for preventing rotation, such as Figures 1-7As shown, this embodiment includes a bellows 1, a pipe connector A2, an adapter structure A3, a fastening nut A4, a pipe connector B5, an adapter structure B6, and a fastening nut B7. The bellows 1 has openings at both ends. Adapter structures A3 and B6 are respectively fixedly connected to corresponding parts of the robot. In this embodiment, adapter structure A3 is machined from sheet metal; adapter structure B6 is cast; adapter structure A3 is fixed to the panel bracket of the SCARA robot forearm with screws; adapter structure B6 is fixedly connected to the base casting of the SCARA robot with screws; adapter structure A3 and adapter structure B6 can also be installed at any suitable position on the robot as needed.

[0031] The pipe fitting A2 is sequentially divided into a pipe fitting A body portion 201, a pipe fitting A mounting flange portion 202, and a pipe fitting A external thread portion 203. The connection method between the pipe fitting A body portion 201, the pipe fitting A mounting flange portion 202, and the pipe fitting A external thread portion 203 adopts existing technology. The pipe fitting A body portion 201 of the pipe fitting A2 is fixed to one end opening of the bellows 1, and the fixing method adopts existing technology. The outer circumferential surface of the pipe fitting A external thread A is provided on the pipe fitting A external thread portion 203 of the pipe fitting A2. The outer circumferential contour size of the pipe fitting A mounting flange portion 202 of the pipe fitting A2 is larger than the outer circumferential contour size of the pipe fitting A external thread portion 203 of the pipe fitting A2.

[0032] The pipe fitting B5 is sequentially divided into a pipe fitting B body portion 501, a pipe fitting B mounting flange portion 502, and a pipe fitting B external thread portion 503. The connection method between the pipe fitting B body portion 501, the pipe fitting B mounting flange portion 502, and the pipe fitting B external thread portion 503 adopts the prior art. The pipe fitting B body portion 501 of the pipe fitting B5 is fixed to the opening at the other end of the bellows 1, and the fixing method adopts the prior art. The outer peripheral surface of the pipe fitting B external thread portion 503 of the pipe fitting B5 has an external thread B. The outer peripheral contour of the pipe fitting B mounting flange portion 502 of the pipe fitting B5 is larger than the outer peripheral contour of the pipe fitting B external thread portion 503 of the pipe fitting B5. The outer peripheral contour of the pipe fitting B mounting flange portion 502 of the pipe fitting B5 is hexagonal. The corrugated pipe 1, pipe connector A 2, and pipe connector B 5 form the main body of the pipeline package. Inside, a wire harness and air tube assembly 001, which includes several wire harnesses and air tubes, is used to pass through, thus protecting and organizing the wire harnesses and air tubes. This type is particularly suitable for externally routed SCARA robots. The corrugated pipe 1, pipe connector A 2, pipe connector B 5, and wire harness and air tube assembly 001 can together form an integrated pipeline package, which can be purchased and assembled as a whole, greatly reducing the difficulty of installation and saving time.

[0033] The adapter structure A3 has a through hole A for the external threaded portion 203 of the pipe connector A2 to pass through. After the external threaded portion 203 of the pipe connector A2 passes through the through hole A, the mounting flange 202 of the pipe connector A2 abuts against one side of the adapter structure A3. Two fastening nuts A4 are connected to the external threaded portion 203 of the pipe connector A2 via the external thread A. The two fastening nuts A4, together with the mounting flange 202 of the pipe connector A2, clamp the adapter structure A3 from the other side, thus completing the basic fixed connection between the pipe connector A2 and the adapter structure A3. The threaded connection between the two fastening nuts A4 and the external threaded portion 203 of the pipe connector A2 effectively improves the anti-rotation effect at the connection between the pipe connector A2 and the adapter structure A3.

[0034] The adapter component B6 has a through hole B601 for the external threaded portion 503 of the pipe connector B5 to pass through. On one side of the adapter component B6, outside the through hole B601, is an anti-rotation groove 602. The anti-rotation groove 602 matches the outer circumferential contour of the mounting flange portion 502 of the pipe connector B5. Figure 4 and Figure 7 As shown, after the external thread portion 503 of pipe connector B5 passes through the through hole B, the mounting flange portion 502 of pipe connector B5 is embedded in the anti-rotation groove 602 and abuts against the bottom surface of the anti-rotation groove 602. A fastening nut B7 is connected to the external thread portion 503 of pipe connector B5 through the external thread B. The fastening nut B7, together with the mounting flange portion 502 of pipe connector B5, clamps the adapter structure B6 from the other side of the adapter structure B6, thereby completing the basic fixed connection between pipe connector B5 and adapter structure B6. Furthermore, the cooperation between the anti-rotation groove 602 and the mounting flange portion 502 of pipe connector B5 effectively improves the anti-rotation effect at the connection between pipe connector B5 and adapter structure B6, and effectively avoids rotation caused by torsional impact due to the robot's rotational inertia.

[0035] Specifically, in this embodiment, the two fastening nuts A4 are bonded to the external thread portion 203 of pipe connector A2 using thread-locking adhesive after installation, which further enhances the reliability of the threaded fastening and effectively improves the performance against torsional impact. In this embodiment, the outer periphery of the mounting flange portion 202 of pipe connector A2 is hexagonal. Figure 6As shown, in this embodiment, a threaded hole A 301 is provided on the adapter structure A 3 and on the outer side of the pipe joint A mounting flange 202 of the pipe joint A 2. The threaded hole A 301 is connected to an anti-rotation screw A (the anti-rotation screw A is hidden in the figure for clarity). The outer peripheral surface of the head of the anti-rotation screw A abuts against one of the corresponding sides of the hexagonal outer peripheral contour of the pipe joint A mounting flange 202 of the pipe joint A 2, which prevents the pipe joint A 2 from rotating left and right. This further prevents the pipe joint A 2 from rotating after long-term wear, and greatly enhances the fastening life of the entire pipe joint A 2.

[0036] Specifically, such as Figure 5 As shown, in this embodiment, five threaded holes B 603 are provided on the other side of the adapter structure B 6 and on the outer periphery of the fastening nut B7. Any two of the threaded holes B 603 can be connected to anti-rotation screws B 8 by threads. The outer periphery of the head of each anti-rotation screw B 8 abuts against one of the corresponding sides of the polygonal outer periphery of the fastening nut B 7, effectively ensuring that the fastening nut B 7 does not loosen or rotate, and further enhancing its anti-rotation performance.
