[0019] like Figures 1 to 6As shown, a heat-resistant stainless steel bar comprises a stainless steel bar body 1 with a central axis in the left-right direction, a cylindrical central matching connection hole 2 running through the entire length is provided at the central axis position of the stainless steel bar body 1, a first heat dissipation safety groove 3 evenly distributed on the left and right and communicating with the central matching connection hole 2 is provided on the outer cylindrical surface of the stainless steel bar body 1, and a second heat dissipation safety groove 4 is provided between the first heat dissipation safety grooves 3 adjacent to each other on the left and right, which constitute the heat dissipation structure of the main structure. The projections of the second heat dissipation safety groove 4 and the first heat dissipation safety groove 3 in the left-right direction intersect, so that the strength of the main structure is better, and when in use, the heat dissipation can be more comprehensive and the heat dissipation efficiency is also higher. The positions of the second heat dissipation safety groove 4 and the first heat dissipation safety groove 3 are staggered, and the second heat dissipation safety groove 4 and the first heat dissipation safety groove 3 are both composed of two groups of matching grooves in the circumferential direction, ensuring that the overall heat dissipation is more efficient and the heat resistance is better when in use. A set of symmetrical welding stable matching grooves 5 are respectively provided on the left and right sides of the stainless steel bar body 1. The welding stable matching grooves 5 are composed of welding fusion grooves evenly distributed around the circumference. The welding fusion grooves penetrate the outer cylindrical surface of the stainless steel bar body 1. When performing end welding, the welding position can be welded more firmly, the welding safety is higher, the welding material fusion efficiency is higher during welding, and welding is easier. It adopts a brand-new structural design. By setting two combinations of staggered heat dissipation safety grooves on the main structure, the internal matching products can be dissipated during use. By setting welding stable matching grooves at the end positions, accurate and firm welding matching can be performed during splicing, which is more convenient to operate during installation, and the welding position has better firmness, which can make more welding materials integrated into the welding position, and has higher strength and durability during later use.

[0020] Preferably, the width of the first heat dissipation safety groove 3 is greater than half of the diameter length of the stainless steel bar body 1, so that the heat dissipation space is larger during use, which can make the heat resistance of the body better.

[0021] Preferably, the projection of the locking and fixing connection hole 7 in the up and down directions is located outside the projection area of ​​the main body matching mounting column 1 in the up and down directions, so that the heat dissipation efficiency of different positions can be higher during the heat dissipation process during use, and a staggered heat dissipation coordination effect can be formed.

[0022] Preferably, the inner side surface of the welding stable matching groove 5 is an arc-shaped structure, which is more convenient during production and processing and has better fluidity when fused with the welding material.

[0023] Preferably, the size of the inner position of the welding stable matching groove 5 is larger than that of the outer position, so that more welding material can be integrated into this position during welding, which has a reliable anti-loosening effect during use and makes the welding position more firm.

[0024] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
