DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on this application.

[0032] Furthermore, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0033] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0034] In order to solve the technical problems in the background technology, such as Figure 1-6 As shown, the present application provides a technical solution: a metal pipe positioning and clamping mechanism, which has the following features:

[0035] The fixed base 1 is a stable foundation that supports the entire positioning and clamping mechanism. The fixed plate 2 is mounted on top of the fixed base 1 and is used to secure other components. Guide rails 3 are installed at both ends of the fixed plate 2, and the guide rails 3 are installed symmetrically to guide the movement of the slider 4. Sliders 4 are installed on the guide rails 3 at both ends. Sliders 4 can slide freely on the guide rails 3 and work together with the guide rails 3 to achieve precise positioning. The sleeve 5 is arranged above the slider 4 and is integrally formed with the slider 4 to ensure the stability of the structure. The axial direction of the sleeve 5 is horizontal, which facilitates the fixing of metal pipes. The U-shaped extension plate 6 is a U-shaped structure with its side walls symmetrically arranged on both sides of the sleeve 5. It is not only fixed to the two sides of the sleeve 5, but also fixedly connected to the slider 4, increasing the stability of the structure. The limit plate 7 is connected to the two side walls of the U-shaped extension plate 6 and is perpendicular to the axis of the sleeve 5. It is used to connect and fix with the telescopic rod 8. The telescopic rod 8 is arranged coaxially with the sleeve 5, with one end connected to the limit plate 7 and the other end extending into the sleeve 5 to achieve the telescopic movement of the positioning block 12. The two ends of the positioning plate 9 are connected to the two side walls of the U-shaped extension plate 6, and a through hole 10 is provided in the middle to accommodate the passage of the telescopic rod 8. Internal threaded holes 11 are provided on both sides of the through hole 10 for threaded connection with the screw 13. The positioning block 12 is provided at the end of the telescopic rod 8 and moves as the telescopic rod 8 is extended or retracted. Screws 13 are rotatably provided on both sides of the positioning block 12, and the screw 13 has external threads. Specifically, the screw 13 passes through the positioning block 12 and can be rotated freely in the positioning block 12, but will not fall off. For example, this effect can be achieved by welding a fixed gasket at the end of the screw 13. The screw 13 is threadedly connected to the internal threaded hole 11 on the positioning plate 9. By rotating the screw 13, the position of the positioning block 12 relative to the positioning plate 9 can be adjusted.

[0036] In actual use, the operator can adjust the position of the positioning block 12 by rotating the screw 13, thereby achieving the clamping and positioning of metal pipes of different sizes. When it is necessary to clamp a metal pipe, the operator places the two ends of the pipe into the sleeves 5 at both ends, and adjusts the approximate position of the positioning block 12 by extending and retracting the telescopic rod 8; then the precise position of the positioning block 12 is adjusted by rotating the screw 13 so that it contacts and clamps the pipe. The design of the limit plate 7 and the U-shaped extension plate 6 ensures the stability and accuracy of the positioning block 12 during the clamping process. The entire mechanism is compact in design, easy to operate, and can adapt to pipes of different lengths, with high practicality and flexibility.

[0037] Furthermore, the V-shaped surface 14 is provided on both sides of the through hole 10 of the positioning plate 9, specifically beside the side walls of the through hole 10. The V-shaped surface 14 is a V-shaped concave surface, the axis of symmetry of which passes through its vertex and the center of the through hole 10, and the two side arms extend upward along the side walls of the through hole 10. The V-shaped surface 14 is tangent to the side walls of the through hole 10, which means that the two side arms of the V-shaped surface 14 extend just along the shape of the side walls of the through hole 10, forming a concave surface with a smooth transition. The main function of the V-shaped surface 14 is to increase the positioning stability of the positioning plate 9 on the metal pipe. When the metal pipe is placed on the positioning plate 9, the V-shaped surface 14 can match the outer surface of the pipe to provide additional support and positioning points.

[0038] It should be noted that the telescopic rod 8 consists of an outer fixed rod 15 and an inner sliding rod 16. This structural design allows the inner sliding rod 16 to telescope within the outer fixed rod 15. The outer fixed rod 15 is the fixed portion of the telescopic rod 8, with its first end connected to the limit plate 7. The outer fixed rod 15 is axially provided with multiple fixing holes that cooperate with elastic protrusions 23 on the inner sliding rod 16 to limit the position of the inner sliding rod 16. The inner sliding rod 16 is the movable portion of the telescopic rod 8, capable of telescoping relative to the outer fixed rod 15. The inner sliding rod 16 extends toward the sleeve 5 and is coaxial with the sleeve 5, ensuring that the movement of the telescopic rod 8 is aligned with the axis of the sleeve 5. The inner sliding rod 16 is surrounded by elastic protrusions 23. These protrusions are located within the inner sliding rod 16 and can extend and retract when the inner sliding rod 16 is extended or retracted. When the inner sliding rod 16 is pulled, the elastic protrusions 23 extend through the fixing holes of the outer fixed rod 15, forming a mating relationship and thus limiting the position of the inner sliding rod 16. The main function of the elastic protrusion 23 is to provide positioning and locking functions when the inner sliding rod 16 is extended and retracted, ensuring that the inner sliding rod 16 is stable in the required position. The design of the elastic protrusion 23 allows the inner sliding rod 16 to achieve self-locking during the extension and retraction process, thereby improving the stability and reliability of the mechanism.

[0039] Furthermore, the anchor 1 utilizes an I-shaped structure, named for its resemblance to the letter "T." This structure offers high stability and load-bearing capacity. The I-shaped structure consists of two parallel, long flanges connected by a central web. The long flanges provide a large surface area for mounting and securing other components, such as the anchor plate 2. The web connects the two flanges, increasing the rigidity and stability of the structure.

[0040] It should be noted that the limit block 17 is arranged at the end of the guide rail 3, specifically at one end or both ends of the guide rail 3, and is used to limit the moving range of the slider 4 on the guide rail 3. The main function of the limit block 17 is to prevent the slider 4 from exceeding the predetermined position when moving on the guide rail 3, and to ensure that the slider 4 moves within a safe range. The limit block 17 can prevent the slider 4 from detaching from the guide rail 3 when subjected to accidental impact or pressure, protecting the entire mechanism from damage. The limit block 17 can be fixed or adjustable, and is designed according to actual needs. The limit block 17 is usually made of a sturdy material, such as metal or hard plastic, to ensure that it has sufficient strength and durability.

[0041] Furthermore, the fixed sleeve 18 is composed of two semicircular rings, which are connected by a hinge to form a complete circular ring structure. One of the semicircular rings is fixedly connected to the sleeve 5, while the other semicircular ring can move relative to the hinge axis. The fixed sleeve 18 is coaxial with the sleeve 5, which means that their central axes coincide. The main function of the fixed sleeve 18 is to provide additional stability and support, especially when the telescopic rod 8 is extended or retracted. The fixed sleeve 18 can extend the support range of the sleeve 5 and help maintain its position stability. The hinge axis is the center point where the two semicircular rings are connected, allowing one semicircular ring to rotate around this axis.

[0042] It should be noted that roller 22 is embedded in the inner wall of fixing sleeve 18. This means that roller 22 is designed to mate with the inner surface of fixing sleeve 18 and can roll along it. The primary function of roller 22 is to reduce friction between fixing sleeve 18 and the metal pipe, allowing the metal pipe to move more smoothly into sleeve 5. The provision of roller 22 enhances the safety of the entire metal pipe positioning and clamping mechanism, preventing accidents caused by excessive friction.

[0043] It should be noted that roller 22 is embedded in the inner wall of fixing sleeve 18 and is tangent to the extended surface of the inner wall of sleeve 5. This means that the outer edge of roller 22 contacts the extended line of the inner wall of sleeve 5, forming a tangent point. The tangent connection between roller 22 and the extended surface of the inner wall of sleeve 5 enables roller 22 to provide continuous support for the metal pipe as it enters sleeve 5.

[0044] It is worth noting that the groove 19 is provided on the outer wall of the movable semicircular ring of the fixing sleeve 18, and is used to cooperate with the protrusion 20 to keep the fixing sleeve 18 in a closed state and limit the opening of the fixing sleeve 18. The protrusion 20 is provided on the guide rod 21 and can slide along the guide rod 21. Its function is to cooperate with the groove 19 to limit the opening of the fixing sleeve 18. The protrusion 20 can be square or cylindrical, and its size and shape need to match the groove 19. The guide rod 21 is hinged to the side wall of the U-shaped extension plate 6, providing a sliding track along which the protrusion 20 can move left and right. When the protrusion 20 slides to the position of the groove 19, the protrusion 20 will be embedded in the groove 19, limiting the opening of the fixing sleeve 18. This matching relationship can serve as a locking mechanism to ensure that the fixing sleeve 18 maintains a stable position when no adjustment is required.

[0045] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
