[0001] The utility model relates to the technical field of stainless steel bars, in particular to a welded stainless steel bar. Background Art
[0002] When stainless steel bars are welded, the end positions are usually fitted with welding components for mating connection. When welding bar products with relatively high precision and strength requirements, docking grooves are usually provided at the welding positions of the bars. However, there is no mating structure for the fusion of welding materials during the mating of the docking grooves, resulting in the inability to guarantee the fusion fluidity during welding, and the welding efficiency at the connection position is relatively poor. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a welded stainless steel bar, which has better overall structural strength. During use, precise combined connection is carried out through the specially welded mating structures provided at both ends, which can guarantee higher connection strength during mating. The welding positions adopt two groups of staggered welding grooves, and the depth of the inner welding groove is greater than that of the outer welding groove. During welding, it can guarantee a larger fusion space for the internal welding materials, better material fluidity during welding, effectively improve the mating efficiency during welding, and make the strength of the welding position higher, more durable during later use, and with higher bearing capacity.
[0004] The technical solution of the utility model is as follows:
[0005] A welded stainless steel bar, including a stainless steel bar main body structure with a central axis in the left-right direction, characterized in that: cylindrical welding stable connection columns are respectively provided at the central positions of the left and right end faces of the stainless steel bar main body structure. A U-shaped first welding mating groove with an opening facing the outer sides in the left and right directions is provided on the outer cylindrical surface of the welding stable connection column. The side of the first welding mating groove close to the central axis of the stainless steel bar main body structure is an arc-shaped structural surface, and the arc-shaped structural surface is parallel to the outer cylindrical surface of the stainless steel bar main body structure. A cylindrical second welding mating groove with a central axis in the left-right direction is provided on the inner arc-shaped structural surface of the first welding mating groove, and the length of the second welding mating groove in the left-right direction is greater than the length of the first welding mating groove.
[0006] Furthermore, the welding stable connection column is connected to the stainless steel bar main body structure by an integral molding method, and a mating sealing connection groove is provided at the connection position between the stainless steel bar main body structure and the welding stable connection column.
[0007] Furthermore, the second welding mating groove is located at the central position in the width direction of the first welding mating groove.
[0008] Further, the central axis of the second welding mating groove is parallel to the central axis of the stainless steel bar main structure.
[0009] Advantages of the present utility model:
[0010] The overall structural strength of the present utility model is better. During use, precise combined connection is carried out through the specially welded mating structures arranged at both ends, which can ensure higher connection strength during mating. The welding positions adopt two groups of staggeredly distributed welding grooves, and the depth of the inner welding groove is greater than that of the outer welding groove.

[0018] Such as Figures 1 to 6As shown in the figure, a welded stainless steel bar includes a stainless steel bar main body structure 1 with a central axis in the left-right direction. At the central positions of the left and right end faces of the stainless steel bar main body structure 1, there is respectively a cylindrical welding stable connection column 2, which can be used as a welding reinforcement structure and an auxiliary structure for connection and cooperation during welding. On the outer cylindrical surface of the welding stable connection column 2, there is a U-shaped first welding fitting groove 3 with an opening facing the outer sides in the left and right directions. The side of the first welding fitting groove 3 close to the central axis of the stainless steel bar main body structure 1 is an arc-shaped structural surface, ensuring a larger area at the inner position during welding fitting and a more reliable fitting strength. The arc-shaped structural surface is parallel to the outer cylindrical surface of the stainless steel bar main body structure 1. On the arc-shaped structural surface inside the first welding fitting groove 3, there is a cylindrical second welding fitting groove 4 with a central axis in the left-right direction, which can ensure that during welding at the inner position, the welding material can flow better into the inner position, making the strength of the fitting position higher. The length of the second welding fitting groove 4 in the left-right direction is greater than the length of the first welding fitting groove 3. During welding, it can make the welding position form an inward concave structure, and the connection position after the welding material flows in and fits can have an anti-loosening welding effect, making the safety during later use more reliable. Its overall structural strength is better. During use, precise combined connection is carried out through the specially welded fitting structures arranged at both ends, which can ensure a higher connection strength during fitting. The welding position adopts two groups of staggered welding grooves, and the depth of the inner welding groove is greater than the depth of the outer welding groove. During welding, it can ensure a larger fusion space for the internal welding material, better material fluidity during welding, effectively improving the fitting efficiency during welding, making the strength of the welding position higher, more durable during later use, and with a higher bearing capacity.
[0019] Preferably, the welding stable connection column 2 is connected to the stainless steel bar main body structure 1 by an integral molding method to ensure better strength at the connection position. It can also be connected in a detachable way, but the connection strength will be relatively lower. At the connection position between the stainless steel bar main body structure 1 and the welding stable connection column 2, there is a fitting sealing connection groove, making the connection more tight and the sealing better when splicing with welding products at both ends.
[0020] Preferably, the second welding fitting groove 4 is located at the central position in the width direction of the first welding fitting groove 3, making the welding strength at the connection position during welding reach the maximum and more durable during later use.
[0021] Preferably, the central axis of the second welding fitting groove 4 is parallel to the central axis of the stainless steel bar main body structure 1, which is more convenient for production and processing, and the fitting stability during welding is also more reliable.
[0022] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements or substitutions can be made, and these improvements or substitutions should also be regarded as the protection scope of the present utility model.
