[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figures 1-5 As shown, the main body of this embodiment is a hose outer bracket assembly fixture, which is adapted to automotive silicone hoses. It consists of four parts: a frame, a hose clamping and positioning system, an assembly positioning mechanism, and a base plate 23 support assembly. It can be adapted to the height of the production line workbench, and no professional tools are required for operation. One person can complete the adjustment.

[0020] Furthermore, the frame adopts three sets of sleeve-type telescopic structures, which are formed by two rotating modules connected in series. Each set of sleeve-type telescopic structures includes an inner tube 3 and an outer tube 4. Both the inner tube 3 and the outer tube 4 are made of 6061 aluminum alloy tubing. The inner tube 3 can slide into the inner cavity of the outer tube 4. Two symmetrical first guide rails 6 are milled along the length direction on the inner wall of the outer tube 4. Two sliders corresponding to the first guide rails 6 are welded to the corresponding positions on the outer wall of the inner tube 3. The sliders move with the inner tube 3, restricting the rotation of the inner tube 3 and allowing telescopic movement only along the axial direction of the outer tube 4.

[0021] Additionally, a threaded hole is drilled on the outside of the outer tube 4, and a hand-tightened wing bolt with a rubber pad that fits into the threaded hole serves as the first locking element 5. When the hand-tightened wing bolt is tightened, the rubber pad presses against the outer wall of the inner tube 3, and the relative positions of the inner tube 3 and the outer tube 4 are locked by friction. It can be fixed by hand without tools.

[0022] In addition, a scale 19 is laser-engraved on the outer side of the inner tube 3 along its length. A red arrow-shaped indicator 20 is pasted on the outer port of the outer tube 4 away from the rotating module. When adjusting, the extension length is read by aligning the indicator 20 with the scale of the inner tube 3.

[0023] Furthermore, the rotating module includes a first connecting shaft 7 and a second connecting shaft 8, both of which are rotatably sleeved at the ends of the inner tube 3 and outer tube 4 of adjacent different sleeve-type telescopic structures. A hinge is welded between the first connecting shaft 7 and the second connecting shaft 8 as a joint 9. The hinge is connected by a stainless steel rotating shaft and can rotate around the rotating shaft to accommodate multiple bending angles of the hose 1.

[0024] Additionally, threaded holes are drilled on the outer sides of the inner tube 3 and outer tube 4 near the first connecting shaft 7 or the second connecting shaft 8, and hand-tightened bolts with nylon washers are used as second locking elements 10. When tightening the bolts, the nylon washers press against the outer side wall of the first connecting shaft 7 or the second connecting shaft 8 to lock the relative position of the connecting shaft and the sleeve, preventing loosening. Threaded holes are drilled on the outer side of the joint 9, and hand-tightened bolts with anti-slip textures are used as third locking elements 11. When tightening the bolts, the inner end of the bolt presses against the pivot of the joint 9 to lock the rotation of the joint 9.

[0025] In addition, an angle scale 21 is laser-engraved on the top surface of joint 9. When adjusting the bending angle, the center of the scale is coaxial with the axis of rotation, and the rotation angle of joint 9 can be read directly without the need for an additional protractor.

[0026] In addition, the hose clamping and positioning system includes clamping modules arranged along the outer sides of the outer tube 4 and inner tube 3 of the frame. The specific structure includes: a horizontally adjusting slider 12, with a dovetail groove milled at its bottom, which slides in conjunction with a dovetail guide rail welded to the outer side of the outer tube 4 of the frame. Threaded holes are drilled on the side of the slider, fitted with hand-tightening bolts with silicone pads. When tightening the bolts, the silicone pads press against the side wall of the guide rail, locking the slider position. A U-shaped clamping component 13, bent into a U-shaped vertical section, has an arc-shaped clamping part 16 welded to its inner side, the radius of which matches the diameter of the hose 1.

[0027] Secondly, each slider is welded with a metal universal joint. The bottom of the horizontal section of the U-shaped clamp 13 is fixed to the universal joint with screws, so that the clamp 13 can be flipped up and down and rotated left and right around the universal joint. After adjustment, the angle can be locked by tightening the bolts on the side of the universal joint.

[0028] It is worth mentioning that the inner side of the arc-shaped clamping part 16 is covered with high-temperature resistant double-sided adhesive and a thick silicone protective layer 22 is attached. The surface of the thick silicone protective layer 22 is provided with deep anti-slip texture. The protective layer 22 is completely attached to the inner wall of the clamping part without any protrusions, which not only avoids scratching the surface of the tube 1, but also increases the friction and prevents the tube 1 from sliding.

[0029] Furthermore, the assembly positioning mechanism is integrated into the inner sides of the vertical and horizontal sections of the U-shaped clamping member 13, and is designed as an integral part of the clamping member 13. It includes a mating groove 17, which is milled into the inner side of the U-shaped clamping member 13 to match the outer contour of the bracket 2 to be assembled. After the bracket 2 is placed in the mating groove 17, its lateral and longitudinal displacement is restricted, requiring only axial positioning. It also includes a receiving seat 27 located on the outer side of the clamping member 13. The receiving seat 27 has a positioning hole 18. The mating groove 17 receives and limits the outer ring of the bracket 2, and the side plate of the bracket 2 abuts and limits the surface of the receiving seat 27. A plastic positioning pin can be inserted into the positioning hole 18. When installing the bracket 2, aligning the mounting hole of the bracket 2 with the positioning hole 18 and inserting the positioning pin allows for quick positioning and prevents the bracket 2 from shifting.

[0030] Furthermore, this device also includes a base plate 23 support assembly for supporting the frame and adjusting its height to adapt to different production line workbenches. This assembly includes a base plate 23 adapted to the workbench, with multiple mounting seats on top of the base plate 23. A telescopic support rod 24 is mounted on the top of each mounting seat, and a support block with a U-shaped groove 25 is welded to the top of the telescopic support rod 24. Notably, the support rod 24 has a hand-tightening bolt on its side; tightening the bolt locks the telescopic length of the inner tube 3, thus adjusting the frame height. An anti-slip pad 26 is attached to the inside of the U-shaped groove 25, increasing friction after the outer tube 4 of the frame is placed in the support block, preventing the frame from sliding within the block. It is also worth mentioning that the top surface of the anti-slip pad 26 is arc-shaped to accommodate the bending state of the frame.

[0031] Operating method Step 1: Adjust the substrate 23 and the frame to match the macroscopic orientation of the tubing 1. Base plate 23 height adjustment: According to the height of the production line workbench, loosen the hand-tightening bolt of the support rod 24, stretch or compress the inner tube 3, so that the top height of the frame is aligned with the workbench surface, and tighten the bolt to lock the support rod 24.

[0032] Frame length adjustment: 1. Loosen the first locking piece 5 of the two sets of sleeves, extend the inner tube 3 of the first set of sleeves out of the outer tube 4, align the indicator mark 20 with the corresponding scale of the inner tube 3, extend the inner tube 3 of the second set of sleeves out of the outer tube 4, align the indicator mark 20 with the corresponding scale of the inner tube 3; 2. According to the actual length of the hose 1, fine-tune the extension of the second set of inner tubes 3 to match the total length of the hose 1, and reserve clamping space, and tighten the first locking piece 5.

[0033] Frame bending adjustment: First, loosen the second locking piece 10 and the third locking piece 11 of the rotating module, then bend the first connecting shaft 7 or the second connecting shaft 8 and the joint 9 to the corresponding angle, aligning them with the corresponding scale on the angle dial 21 to adapt to the inflection point angle of the hose 1, and then tighten the third locking piece 11. The same applies to other inflection points.

[0034] Step 2: Adjust the clamping module to fix the posture of hose 1. Slider position adjustment: Loosen the fourth locking member 15 of the clamping module, move the module to the corresponding position, which should include the position of the bracket 2 to be installed, and then tighten the fourth locking member 15.

[0035] Adjusting the angle of clamping member 13: Loosen the universal joint bolts, bend the clamping members 13 on both sides of the first inflection point to fit against the curved surface of the hose 1, that is, the inner protective layer 22 of the arc-shaped clamping part 16 is completely attached to the hose 1 and the bolts are tightened.

[0036] Step 3: Position bracket 2 to complete assembly. Bracket 2 installation: Place bracket 2 into mating groove 17, align bracket 2 mounting hole with positioning hole 18, and insert positioning pin; fix bracket 2 with bolts so that bracket 2 is installed outside of rubber tube 1, and pull out positioning pin after fixing to complete assembly.

[0037] Step 4: Replace tubing 1 or store it away. To replace the old hose 1 with the same model: simply remove the old hose 1 and insert the new hose 1 into the clamp 13. No readjustment is required. To change to a different model: Loosen all locking parts and repeat steps 1-3.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
