[0001] The utility model relates to the field of hardware component decorations, in particular to a socket-type metal elbow. Background Art

[0002] In recent years, with the improvement of people's living standards, people have higher and higher requirements for home decoration, so various hardware components and decorations have emerged, adding many beautiful colors to our lives. However, taking specific pipeline systems such as stair handrails and corridor railings as examples, existing elbow connectors made of stainless steel and other materials generally adopt direct welding, threaded fixing and other methods. These methods require a lot of manpower and material resources during the installation process. Because there is no socket-type straight pipe section structure at both ends, it cannot be used for socket-type welding or socket-type bonding when the inner socket is inserted into the pipeline. During the installation process, the existing elbows are very inconvenient in aligning the pipeline ports and adjusting the angles, and the work efficiency is low.

[0003] In view of this, the inventor of the present utility model invented a socket-type metal elbow, which can solve the above-mentioned problems in the prior art. Summary of the invention

It has a simple structure, beautiful appearance, and convenient installation, which improves the overall aesthetics. The socket-type straight pipe section structural design makes the connection between the socket-type metal elbow and the pipe more secure, and it is not easy to loosen or fall off during installation. During the installation process, it only needs to insert the elbow socket-type straight pipe section structure into the pipe to achieve quick installation and use. It can also be rotated with other appropriately matched socket-type metal elbows according to different angles to form different angles and shapes for free combination and use in the required specific pipe system structure.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a socket-type metal elbow, characterized in that: the socket-type metal elbow includes an elbow main structure of an arc-shaped circular pipe section and a first inner socket-type straight pipe section structure and a second inner socket-type straight pipe section structure, each end of the first inner socket-type straight pipe section structure and the second inner socket-type straight pipe section structure are fixedly arranged at both ends of the elbow main structure in an integrally formed manner, and the center lines of the first inner socket-type straight pipe section structure and the second inner socket-type straight pipe section structure are respectively perpendicular to the corresponding port cross-sections of the elbow main structure, and respectively pass through the center of the circle of the corresponding port cross-sections of the elbow main structure.

[0006] Preferably, the angle of the elbow main structure is preferably one of 22.5 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees, etc.

[0007] Preferably, the first internal bell-and-spigot straight pipe section structure and the second internal bell-and-spigot straight pipe section structure respectively form an inclined slope structure of 90 degrees or less than 90 degrees with the corresponding ports of the elbow main structure 1, or other suitable structures.

[0008] Preferably, the first internal bell-and-spigot straight pipe section structure and the second internal bell-and-spigot straight pipe section structure are both preferably short straight circular pipe section structures, and the outer wall diameters of the first internal bell-and-spigot straight pipe section structure and the second internal bell-and-spigot straight pipe section structure are the same, and are both less than twice the wall thickness value of the outer wall diameter of the corresponding port of the elbow main structure, and the value range of less than is between 0.7-20mm.

[0009] Preferably, when the socket-type metal elbow is made of the same material, the material is preferably one of carbon steel, white steel, aluminum alloy, stainless steel, titanium alloy, copper, copper alloy and the like.

[0010] Preferably, when the socket-type metal elbow is composed of different materials, the socket-type metal elbow includes a main structural part and auxiliary materials, and the material of the main structural part is preferably one of carbon steel, white steel, aluminum alloy, stainless steel, titanium alloy, copper, copper alloy, etc.

[0011] Compared with the prior art, the beneficial effect is that the socket-type metal elbow of the utility model can be used independently or in combination with other suitably matched socket-type metal elbows. It adopts an internal socket-type straight pipe section structure to penetrate into the pipeline for internal socket-type welding or internal socket-type bonding, etc. It can also be freely combined with other suitably matched socket-type metal elbows according to actual needs to form a variety of different angles and shapes, thereby improving the flexibility of elbow and pipeline installation, effectively solving the problems existing in the existing elbow connectors, having important economic value and application value, and can be widely used in various specific pipeline system structures such as stair handrails, corridor railings, etc., making the operation more convenient and simple, the structure beautiful, seamless, and more standardized, and at the same time greatly reducing the labor intensity and difficulty of the operator, saving working time and improving work efficiency.
