Description

Technical Field

[0001] This utility model relates to the field of pipe fitting connection technology, specifically to an adjustable pipe connector. Background Technology

[0002] This application relates to pipe connectors, not pipes for fluid flow, but pipes used for the construction of structures such as frames.

[0003] In existing technologies, bolted connections are commonly used to secure the pipes together. This method involves creating bolt holes at pre-designed connection points on the pipes, inserting bolts, and tightening nuts to securely connect adjacent pipes. However, this conventional bolted connection method generally suffers from exposed bolts. Exposed bolts are not only susceptible to corrosion from the external environment, leading to thread corrosion and affecting connection strength and disassembly / maintenance, but also pose a collision hazard in areas with high pedestrian traffic due to their protruding structure. Furthermore, they negatively impact the aesthetics and neatness of the overall frame structure. Utility Model Content

[0004] In view of the problems pointed out in the background art, this utility model proposes an adjustable pipe connector to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An adjustable pipe connector includes a tubular connector, which consists of a straight pipe section and an arc-shaped pipe section, with the end of the arc-shaped pipe section being a closed circular surface.

[0007] The connector includes two connectors, namely the first connector and the second connector;

[0008] The first connector has a protruding circular boss at the center of its circular surface, and also includes a threaded hole that passes through the boss and the center of the circular surface of the first connector.

[0009] The second connector has a concave circular groove at the center of its circular surface, and also includes a through hole that passes through the center of the circular surface of the second connector.

[0010] The circular surfaces of the first and second connectors are mated together, the boss and the groove are fitted together, and fastening bolts are connected in the through hole and the threaded hole.

[0011] The present invention is further provided that the side wall of the second connector is provided with an operation opening corresponding to the through hole.

[0012] The present invention is further configured such that the outer diameter of the straight tube portion is smaller than the outer diameter of the arc-shaped tube portion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] For reference as follows Figures 1-3 The present invention will be described as follows:

[0026] Example: An adjustable pipe connector includes a tubular connector, which is composed of a straight pipe part 1 and an arc-shaped pipe part 2. The end of the arc-shaped pipe part 2 is a closed circular surface 3.

[0027] The connector includes two connectors, namely the first connector 41 and the second connector 42.

[0028] The first connector 41 has a protruding circular boss 5 at the center of its circular surface 3, and also includes a threaded hole 6 that passes through the boss 5 and the center of the circular surface 3 of the first connector 41.

[0029] The circular surface 3 of the second connector 42 has a concave circular groove 7 at its center, and also includes a through hole 8 that passes through the center of the circular surface 3 of the second connector 42.

[0030] When the two connectors are connected, the circular surfaces 3 of the first connector 41 and the second connector 42 align with each other. The circular boss 5 and the circular groove 7 achieve precise positioning through shape adaptation, ensuring accurate relative positions between the connectors. Based on this, the fastening bolt 9 passes through the through hole 8 of the second connector 42 and is screwed into the threaded hole 6 of the first connector 41. The fastening force generated by the threaded connection firmly fixes the two circular surfaces 3 together, thereby achieving a stable connection between the first connector 41 and the second connector 42.

[0031] To facilitate the installation and operation of the fastening bolt 9, an operating opening 10 corresponding to the through hole 8 is provided on the side wall of the second connecting body 42. During installation, the fastening bolt 9 can enter the interior of the second connecting body 42 through the operating opening 10 and connect with the through hole 8 and the threaded hole 6. During tightening or disassembly, the tool used to rotate the fastening bolt 9 can also be inserted through the operating opening 10 and engage with the hexagonal recess 91 on the threaded head of the fastening bolt 9. This design avoids the disadvantage of exposed bolts in traditional bolted connections. The fastening bolt 9 is completely located inside the connecting body, effectively preventing external environmental corrosion of the bolt, reducing the risk of thread corrosion, and extending the service life of the connecting parts. At the same time, it eliminates the potential collision hazards caused by protruding bolts, improving safety in use. Furthermore, since there are no exposed bolts, the overall structure is simpler and more aesthetically pleasing.

[0032] The outer diameter of the straight pipe section 1 is smaller than the outer diameter of the curved pipe section 2, and the inner diameter of the straight pipe section 1 is smaller than the inner diameter of the curved pipe section 2. The main function of the straight pipe section 1 is to connect with the pipes that need to be connected. Its smaller outer and inner diameters allow it to adapt to pipes of various diameters, achieving a tight connection and ensuring connection strength and stability. The curved pipe section 2, on the other hand, serves as the fixed connection between the connectors. Its larger diameter design provides ample space for the internal connection structure and also enhances the structural strength of the connector itself.

[0033] The head of the fastening bolt 9 has a hexagonal recess 91. A tool is inserted into the recess to rotate the fastening bolt 9.

[0034] Both connectors have circular mating surfaces (3), a design that allows for angle adjustment. During actual installation, the two connectors can rotate around their mating center, flexibly adjusting the connection angle according to different installation requirements and site conditions. This greatly improves the connector's applicability, enabling it to meet the construction requirements of various complex frame structures.

[0035] The operating opening 10 is located on the straight tube section 1 and / or the curved tube section 2.

[0036] When constructing frames or other structures, the pipes that need to be connected are first connected to the straight pipe section 1 of the connector. Because the outer and inner diameters of the straight pipe section 1 are smaller than those of the curved pipe section 2, it can tightly fit various types of pipes, ensuring a secure connection.

[0037] Next, the connectors are assembled. The circular boss 5 of the first connector 41 is aligned with the circular groove 7 of the second connector 42 and inserted, completing the initial positioning and precisely fixing their relative positions. Subsequently, through the operating hole 10 on the side wall of the second connector 42, the fastening bolt 9 is inserted into the through hole 8 and then screwed into the threaded hole 6 of the first connector 41. With the help of a tool and the hexagonal recess 91 on the threaded head of the fastening bolt 9, the bolt is rotated. As the thread is screwed in, a tightening force is generated, causing the circular surfaces 3 of the two connectors to fit tightly together, achieving a stable connection, and thus connecting the two pipes.

[0038] When the pipe angle needs to be adjusted, since the mating surfaces of the two connectors are circular, they can rotate relative to each other around the mating center. The connection angle can be flexibly changed according to the actual installation scenario and needs to meet the requirements of pipe connections with different directions in the frame construction.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
