Description

Technical Field

[0001] This utility model relates to the field of gas pipelines, and in particular to an adjustable-angle protective sleeve for gas pipelines penetrating walls. Background Technology

[0002] In gas pipeline installation and renovation, protective sleeves are needed to protect and seal the pipes when they pass through walls, preventing them from being rubbed by the wall and corroded by moisture. At the same time, they isolate gaps to prevent gas leaks or rainwater infiltration. These sleeves are important auxiliary components for the safe operation of gas systems and are widely used in various gas pipeline wall penetration construction scenarios in residential and commercial places.

[0003] Most existing gas pipeline wall penetration protective sleeves have fixed angles. When faced with irregular walls in old house renovations or non-vertical wall penetration scenarios such as outdoor pipelines entering the house at an angle, it is necessary to re-drill holes or cut the pipeline, which is inconvenient to construct and damages the structure. A few sleeves that can be finely adjusted lack a reliable locking structure. With long-term use, the angle is prone to shift due to vibration and external forces, which can cause pipeline wear, sealing failure and other safety hazards. Utility Model Content

[0004] In view of this, the present invention provides an adjustable-angle gas pipeline wall penetration protective sleeve. The main technical problem to be solved is that most existing gas pipeline wall penetration protective sleeves have a fixed angle. When facing non-vertical wall penetration scenarios such as irregular walls in old house renovations or outdoor pipelines entering the house at an angle, it is necessary to re-drill holes or cut the pipeline, which is inconvenient to construct and damages the structure. A few sleeves with adjustable angles lack a reliable locking structure. With long-term use, the angle is prone to shift due to vibration and external forces, which can cause pipeline wear, sealing failure and other safety hazards.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable-angle gas pipeline wall-penetrating protective sleeve, comprising a first sleeve, a corrugated pipe fixedly connected to the side wall of the first sleeve, a second sleeve fixedly connected to the end of the corrugated pipe away from the first sleeve, a fixing plate fixedly connected to the outer surface of the first sleeve, a first connecting plate fixedly connected to the side wall of the fixing plate, a first rotating groove formed inside the first connecting plate, a worm gear rotatably mounted on the inner wall of the first rotating groove, a disc fixedly connected to the upper surface of the worm gear, and the upper surface of the disc... The first connecting plate has a first internal hexagonal groove, and the outer surface of the disc has six first limiting grooves. A fixing frame is fixedly connected to the upper surface of the first connecting plate, and a spring is fixedly connected to the inner wall of the fixing frame. One end of the spring is fixedly connected to a limiting strip, which is located inside the first limiting groove. A second rotating groove is formed inside the first connecting plate, and a worm gear is rotatably mounted on the inner surface of the second rotating groove. The worm gear meshes with a worm. A first connecting shaft is fixedly connected to the side wall of the worm gear, and a positioning and fixing component is fixedly connected to the side of the first connecting shaft away from the worm gear.

[0006] By adopting the above technical solution, it can be flexibly adapted to non-vertical wall penetration scenarios, and can be quickly locked after adjusting the angle to avoid angle deviation during use.

[0007] As a further description of the above technical solution: The upper surface of the fixed frame is provided with a first moving groove, and a locking block is fixedly connected to the upper surface of the limiting strip. The locking block is located on the inner wall of the first moving groove.

[0008] By adopting the above technical solution, when it is necessary to adjust the angle or pull the limiting strip away from the first limiting groove, the locking block slides along the first moving groove, which can prevent the limiting strip from shifting or falling off due to spring force or external force, and ensure that the limiting strip always moves within the preset trajectory.

[0009] As a further description of the above technical solution: The positioning and fixing assembly includes a second connecting plate, which is fixedly connected to the side of the first connecting shaft away from the worm gear. A second connecting shaft is fixedly connected to the side of the second connecting plate away from the first connecting shaft, and a mounting plate is fixedly connected to the side of the second connecting shaft away from the second connecting plate.

[0010] By adopting the above technical solution, the second connecting plate, the second connecting shaft, and the mounting plate form a continuous connection structure, wherein the second connecting plate achieves a stable connection with the first connecting shaft.

[0011] As a further description of the above technical solution: The mounting plate has a second movable groove inside, and a double threaded screw is rotatably installed on the inner wall of the second movable groove. A bolt head is fixedly connected to the upper surface of the double threaded screw, and a second internal hexagonal groove is formed on the upper surface of the bolt head.

[0012] By adopting the above technical solution, the double-threaded screw can be easily driven to rotate using an internal hexagon tool through the second internal hexagon slot.

[0013] As a further description of the above technical solution: The outer surface of the double-threaded lead screw is threaded with a movable block, and there are two movable blocks. The side wall of the movable block is fixedly connected with a clamping plate, and the inner surface of the clamping plate is fixedly connected with a friction pad.

[0014] By adopting the above technical solution, when the double-threaded screw rotates, the positive and negative threads on its surface can drive the two moving blocks to move synchronously in opposite directions, thereby enabling the clamping plate to clamp or release the second sleeve. The friction pad inside the clamping plate can increase the friction with the surface of the second sleeve, preventing the second sleeve from sliding after clamping, and can buffer the squeezing damage to the surface of the second sleeve by the clamping force, thus protecting the second sleeve while ensuring the fixation is firm.

[0015] As a further description of the above technical solution: The inner wall of the second moving groove is provided with a second limiting groove, and there are two second limiting grooves. The side wall of the moving block is fixedly connected with a limiting block, and there are two limiting blocks. The limiting blocks are located inside the second limiting groove.

[0016] By adopting the above technical solution, the movement of the moving block can be restricted by the cooperation of the second limiting groove and the limiting block, and the movement trajectory of the moving block can be strictly constrained.

[0017] By employing the above technical solution, the adjustable-angle gas pipeline wall-penetrating protective sleeve of this utility model has at least the following beneficial effects: Compared with existing technologies, this adjustable-angle gas pipeline wall-penetrating protective sleeve utilizes a locking block, a limiting strip, a first limiting groove, a disc, a first internal hexagonal groove, a worm gear, a worm wheel, a first connecting shaft, a positioning and fixing component, a second sleeve, and a spring. When angle adjustment is needed, the locking block is first moved to disengage the limiting strip from the first limiting groove. Then, using an internal hexagonal tool to rotate the first internal hexagonal groove on the disc causes the worm gear to rotate, which in turn drives the positioning and fixing component to adjust the angle via the first connecting shaft. This ultimately achieves angle adaptation between the entire second sleeve and the gas pipeline, meeting the needs of non-perpendicular wall penetration scenarios and solving the problem of traditional sleeves having fixed angles and being unable to flexibly adapt to pipeline routes. Once the angle is adjusted to the correct position, the spring... The elastic force of the spring pushes the limiting strip into the corresponding first limiting groove, which can quickly lock the current angle and prevent the angle from shifting due to vibration, external force or other factors during use. Compared with the existing protective sleeves, most of which have a fixed angle, they require re-drilling or cutting pipes when facing irregular walls in old house renovations or non-vertical wall penetration scenarios such as outdoor pipes entering the house at an angle. This is inconvenient and damages the structure. A few that can be finely adjusted lack a reliable locking structure. With long-term use, the angle is prone to shift due to vibration or external force, which can cause pipe wear, sealing failure and other safety hazards. This adjustable gas pipeline wall penetration protective sleeve can flexibly adapt to non-vertical wall penetration scenarios. After adjusting the angle, it can be quickly locked to prevent the angle from shifting during use. Attached Figure Description

[0020] Reference Figure 1-6The adjustable-angle gas pipeline through-wall protective sleeve provided by this utility model includes a first sleeve 1, a corrugated pipe 2 fixedly connected to the side wall of the first sleeve 1, and a second sleeve 3 fixedly connected to the end of the corrugated pipe 2 away from the first sleeve 1. The gas pipeline is placed inside the first sleeve 1, the corrugated pipe 2, and the second sleeve 3. A fixing plate 4 is fixedly connected to the outer surface of the first sleeve 1. The fixing plate 4 can be fixedly connected to the wall surface by bolts. A first connecting plate 5 is fixedly connected to the side wall of the fixing plate 4. A first rotating groove 7 is opened inside the first connecting plate 5, and a first rotating groove 7 is rotatably installed on the inner wall of the first rotating groove 7. A worm gear 8 has a disk 9 fixedly connected to its upper surface. The upper surface of the disk 9 has a first internal hexagonal groove 10, and its outer surface has six first limiting grooves 14. A fixing frame 11 is fixedly connected to the upper surface of a first connecting plate 5. A spring 12 is fixedly connected to the inner wall of the fixing frame 11, and a limiting strip 13 is fixedly connected to one end of the spring 12. The limiting strip 13 is located inside the first limiting groove 14. A second rotating groove 15 is formed inside the first connecting plate 5, and a worm wheel 16 is rotatably mounted on the inner surface of the second rotating groove 15. The worm wheel 16 meshes with the worm gear 8, and the side wall of the worm wheel 16 is fixed... A first connecting shaft 17 is fixedly connected to the first connecting shaft 17, with a positioning and fixing component 6 fixedly connected to the side of the first connecting shaft 17 away from the worm gear 16. When the angle needs to be adjusted, firstly, the locking block 19 is moved to disengage the limiting strip 13 from the first limiting groove 14. Then, when the first hexagonal groove 10 on the disc 9 is rotated using an Allen wrench, the worm 8 drives the worm gear 16 to rotate, which in turn drives the positioning and fixing component 6 to adjust the angle through the first connecting shaft 17. Finally, the angle of the entire second sleeve 3 is adapted to the gas pipeline, meeting the needs of non-vertical wall penetration scenarios and solving the problem of traditional sleeves having fixed angles and being unable to flexibly adapt to pipeline routes. Once the angle is adjusted to the correct position, the elastic force of the spring 12 pushes the limiting strip 13 into the corresponding first limiting groove 14, quickly locking the current angle and preventing angle deviation due to vibration, external force, or other factors during use. A first moving groove 18 is provided on the upper surface of the fixed frame 11, and a locking block 19 is fixedly connected to the upper surface of the limiting strip 13. The locking block 19 is located on the inner wall of the first moving groove 18. By providing the first moving groove 18 on the fixed frame 11 and fixing the locking block 19 to the limiting strip 13, ensuring the locking block 19 is located on the inner wall of the first moving groove 18, the movement trajectory of the limiting strip 13 is constrained. When angle adjustment is required or the limiting strip 13 needs to be pulled away from the first limiting groove 14, the locking block 19 slides along the first moving groove 18, preventing the limiting strip 13 from shifting or falling off due to the elastic force of the spring 12 or external force. This ensures the limiting strip 13 always moves within the preset trajectory, improving the smoothness of angle adjustment operation and structural reliability, and preventing angle locking failure due to misalignment of the limiting strip 13.

[0021] The positioning and fixing assembly 6 includes a second connecting plate 601, which is fixedly connected to the side of the first connecting shaft 17 away from the worm gear 16. A second connecting shaft 602 is fixedly connected to the side of the second connecting plate 601 away from the first connecting shaft 17, and a mounting plate 603 is fixedly connected to the side of the second connecting shaft 602 away from the second connecting plate 601. The second connecting plate 601, the second connecting shaft 602, and the mounting plate 603 form a continuous connection structure, wherein the second connecting plate 601 achieves stable connection with the first connecting shaft 17. The mounting plate 603 has a second movable groove 604 inside, and a double-threaded screw 605 is rotatably mounted on the inner wall of the second movable groove 604. A bolt head 606 is fixedly connected to the upper surface of the double-threaded screw 605. A second internal hexagonal groove 607 is formed on the upper surface of the bolt head 606. The double-threaded screw 605 can be easily driven to rotate through the second internal hexagonal groove 607 using an internal hexagonal tool. Two movable blocks 608 are threadedly connected to the outer surface of the double-threaded screw 605. A clamping plate 609 is fixedly connected to the side wall of the 08, and a friction pad 610 is fixedly connected to the inner surface of the clamping plate 609. When the double-threaded screw 605 rotates, the positive and negative threads on its surface can drive the two moving blocks 608 to move synchronously in opposite directions, thereby enabling the clamping plate 609 to clamp or release the second sleeve 3. The friction pad 610 inside the clamping plate 609 can increase the friction with the surface of the second sleeve 3, prevent the second sleeve 3 from sliding after clamping, and buffer the squeezing damage to the surface of the second sleeve 3 caused by the clamping force. While ensuring the fixation is firm, the second sleeve 3 is protected. The inner wall of the second moving groove 604 is provided with a second limiting groove 611. There are two second limiting grooves 611. The side wall of the moving block 608 is fixedly connected with a limiting block 612. There are two limiting blocks 612. The limiting blocks 612 are located inside the second limiting groove 611. The movement of the moving block 608 can be restricted by the cooperation of the second limiting groove 611 and the limiting block 612. The movement trajectory of the moving block 608 can be strictly constrained.

[0022] Working principle: When the angle needs to be adjusted, first move the locking block 19 to drive the limiting strip 13 to disengage from the first limiting groove 14. Then, use an Allen wrench to rotate the first Allen groove 10 on the disc 9. The worm gear 8 drives the worm wheel 16 to rotate, which in turn drives the positioning and fixing component 6 to adjust the angle through the first connecting shaft 17. Finally, the angle of the entire second sleeve 3 is adapted to the gas pipeline, which meets the needs of non-vertical wall penetration scenarios and solves the problem of fixed angle of traditional sleeves and inability to flexibly adapt to pipeline routing. When the angle is adjusted to the correct position, the elastic force of the spring 12 pushes the limiting strip 13 into the corresponding first limiting groove 14, which can quickly lock the current angle and avoid angle deviation caused by vibration, external force and other factors during use. When the double threaded screw 605 rotates, the positive and negative threads on its surface can drive the two moving blocks 608 to move synchronously in opposite directions, thereby enabling the clamping plate 609 to clamp or release the second sleeve 3.
