Description

Technical Field

[0001] This invention relates to the technical field of pipe positioning, and more particularly to an adjustable positioning pipe fitting. Background Technology

[0002] Currently, in the installation and application of pipe bends, the positioning plate is a key structure for ensuring installation accuracy. In the industry, the positioning plate is typically connected to the pipe bend body using either dot-matrix fixing or welding. Under this process, the position of the positioning plate relative to the pipe bend is unique and immutable.

[0003] However, this fixing method has significant limitations in practical applications. Due to differences in the on-site installation environment, pipeline layout, and bracket positions of end customers, the preset positioning plate position often cannot perfectly match the actual on-site requirements. When installation deviations occur, since the positioning plate cannot be adjusted, it can only be compensated for by on-site hole enlargement, secondary processing, or forced assembly. This not only increases the construction difficulty and reduces installation efficiency, but may also introduce additional stress due to forced assembly, affecting the long-term stability of the pipeline system.

[0004] Therefore, how to improve the adjustability of the positioning plate of the pipe bend during the installation process to adapt to diverse on-site installation needs is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an adjustable positioning pipe fitting, which allows the positioning plate to be adjusted at will before locking, thereby reducing construction difficulty, improving installation efficiency, and enhancing the long-term stability of the pipeline system.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An adjustable positioning pipe fitting includes: a positioning plate and a clamping assembly. The positioning plate is sleeved on the pipe fitting. The clamping assembly includes: a positioning structure and a clamping structure. A portion of the positioning structure abuts against the positioning plate, and a space is formed between the other portion of the positioning structure and the positioning plate. The clamping structure is connected to the other portion of the positioning structure. One or more fasteners are used to lock another part of the positioning structure to the positioning plate to compress the space, causing the inner circumference of the clamping structure to shrink and clamp onto the pipe.

[0007] In the aforementioned adjustable positioning fitting, when the fastener is not locked between the positioning structure and the positioning plate, at least a portion of the clamping structure abuts against the fitting.

[0008] The aforementioned adjustable positioning tube fitting, wherein the clamping assembly includes: at least two clamping members, a plurality of the clamping members being distributed along the periphery of the tube fitting, each clamping member including: a positioning member and a pressing member, a portion of the positioning member abutting against the positioning plate, the other portion of the positioning member forming the space between itself and the positioning plate, and the pressing member being connected to the other portion of the positioning member; One or more of the fasteners are used to lock another part of the positioning member to the positioning plate to compress the space, so that the inner wall of the pressing member is pressed against the outer wall of the pipe.

[0009] In the aforementioned adjustable positioning fitting, when the fastener is not locked between the positioning member and the positioning plate, at least a portion of the clamping member abuts against the fitting.

[0010] In the aforementioned adjustable positioning fitting, another part of the positioning member has a plane on the side near the positioning plate, which forms the space between the plane and the positioning plate, and the plane forms an angle α with the positioning plate.

[0011] In the aforementioned adjustable positioning fitting, the included angle α is no greater than 30°.

[0012] In the aforementioned adjustable positioning tube fitting, the inner wall of the clamping member is an arc surface. When the fastener locks the positioning member and the positioning plate, the arc surface fits against the outer wall of the tube fitting.

[0013] The aforementioned adjustable positioning fitting, wherein the positioning plate has one or more threaded holes; The fastener is a fastening screw, which passes through the positioning member and is threadedly connected to the threaded hole; The locking force of the fastening screw connected to the threaded hole reduces the distance between the positioning plate and the positioning member, thereby pressing the inner wall of the clamping member against the outer wall of the pipe.

[0014] In the aforementioned adjustable positioning fitting, the positioning element has one or more through holes, the threaded hole corresponds to the through hole, and the fastening screw passes through the through hole and is threadedly connected to the threaded hole.

[0015] In the aforementioned adjustable positioning tube fitting, a plurality of clamping members are distributed at equal intervals along the circumferential direction of the tube fitting; Each of the positioning elements is equipped with at least two of the fasteners.

[0016] The present invention, by employing the above-mentioned technology, has the following positive effects compared with the prior art: This invention allows for easy adjustment of the positioning plate's position on the pipe fitting, followed by locking it to the pipe fitting using clamping components and fasteners. This reduces construction difficulty, improves installation efficiency, and enhances the long-term stability of the pipeline system. Attached Figure Description

A part of the positioning structure 3 abuts against the positioning plate 1, and a space 6 is formed between the other part of the positioning structure 3 and the positioning plate 1. The clamping structure 4 is connected to the other part of the positioning structure 3.

[0029] Furthermore, as a preferred embodiment, another part of the positioning structure 4 is locked to the positioning plate 1 by one or more fasteners 7 to compress the space 6, causing the inner circumference of the clamping structure 5 to shrink and clamp onto the pipe 3.

[0030] Furthermore, as a preferred embodiment, when the fastener 7 is not locking the positioning structure 4 and the positioning plate 1, at least a portion of the clamping structure 5 abuts against the pipe fitting 3.

[0031] The present invention allows the positioning plate 1 to be adjusted at will on the pipe fitting 3, and then locked to the pipe fitting 3 by the clamping assembly 2 and fasteners, which reduces the construction difficulty, improves the installation efficiency, and improves the long-term stability of the pipeline system.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention.

[0033] In addition to the above, the present invention also has the following embodiments: In a further embodiment of the present invention, the clamping assembly 2 includes at least two clamping members 8, and a plurality of clamping members 8 are distributed along the periphery of the pipe 3. Each clamping member 8 includes a positioning member 81 and a pressing member 82. A portion of the positioning member 81 abuts against the positioning plate 1, and another portion of the positioning member 81 forms a space 6 with the positioning plate 1. The pressing member 82 is connected to the other portion of the positioning member 81.

[0034] In a further embodiment of the present invention, another part of the positioning member is locked to the positioning plate 1 by one or more fasteners 7 to compress the space 6, so that the inner wall of the pressing member 82 is pressed against the outer wall of the pipe 3.

[0035] Furthermore, the clamping component 8 is a one-piece structure.

[0036] Furthermore, the clamping member 8 has a certain elasticity. As the fastener 7 continuously locks the positioning member 81 and the positioning plate 1, the connection between the positioning member 81 and the pressing member 82 is squeezed, thereby causing the pressing member 82 to continuously press against the pipe 3.

[0037] Furthermore, the positioning structure 4 includes multiple positioning elements 81, which are separate structures and are distributed at equal intervals along the periphery of the pipe.

[0038] Furthermore, the clamping structure 5 includes multiple clamping elements 82, which are separate structures and are distributed at equal intervals along the periphery of the pipe.

[0039] In a further embodiment of the present invention, when the fastener 7 is not locking the positioning member 81 and the positioning plate 1, at least a portion of the clamping member 82 abuts against the pipe 3.

[0040] In a further embodiment of the present invention, another part of the positioning member 81 has a plane 9 on the side near the positioning plate 1, the plane 9 and the positioning plate 1 forming a space 6, and the plane 9 and the positioning plate 1 forming an included angle α.

[0041] In a further embodiment of the present invention, the included angle α is no greater than 30°.

[0042] The cross-section of space 6 is triangular.

[0043] In a further embodiment of the present invention, the inner wall of the clamping member 82 is an arc surface. When the fastener 7 locks the positioning member 81 and the positioning plate 1, the arc surface fits against the outer wall of the pipe 3.

[0044] In a further embodiment of the present invention, the positioning plate 1 has one or more threaded holes 11.

[0045] In a further embodiment of the present invention, the fastener 7 is a fastening screw, which passes through the positioning member 81 and is threadedly connected to the threaded hole 11.

[0046] In a further embodiment of the present invention, the locking force of the fastening screw connected to the threaded hole 11 is used to reduce the distance between the positioning plate 1 and the positioning member 81, so that the inner wall of the pressing member 82 is pressed against the outer wall of the tube 3.

[0047] In a further embodiment of the present invention, the positioning member 81 has one or more through holes 12, and the threaded hole 11 corresponds to the through hole 12. The fastening screw passes through the through hole 12 and is threadedly connected to the threaded hole 11.

[0048] Furthermore, during the process of tightening the screw and locking the threaded hole 11, the aforementioned included angle gradually decreases until the clamping member 82 clamps the outer wall of the tube 3.

[0049] In a further embodiment of the present invention, a plurality of clamping members 8 are distributed at equal intervals along the circumferential direction of the pipe 3. This increases the clamping force of the clamping assembly 2 on the pipe.

[0050] In a further embodiment of the present invention, at least two fasteners 7 are installed on each positioning member 81. This improves the tightness balance between the clamping member 8 and the positioning plate 1.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
