[0020] like Figures 1 to 7As shown, a rotating stainless steel bar comprises a stainless steel bar main structure 1, the end surface of which is provided with a cylindrical rotating mounting seat 2, which enables the stainless steel bar to be installed and matched during the overall installation. The rotating mounting seat 2 has a stepped rotation reference matching groove 3 at its center, which can be matched with the stop structure of the rotating power assembly. During use, it can provide a reference match for the rotation of the bar and ensure more stable rotation. The rotating mounting seat 2 is provided with cylindrical first fixing holes 4 evenly distributed around the circumference, and second fixing holes 5 evenly distributed around the circumference. The rotating mounting seat 2 can be fastened to the power assembly as needed, and can be fastened at any position or simultaneously, which enhances the convenience of fastening. The first fixing holes 4 and the second fixing holes 5 are staggered, ensuring more stable and reliable fitting of the overall structure. The second fixing holes 5 are projected in the vertical direction in an arc shape, which can meet the requirements of various fastening positions during fastening. The upper end of the rotating mounting seat 2 is located between the second fixed fitting hole 5 and the rotating reference fitting groove 3 and is provided with a first positioning and stabilizing fitting boss 6 that is evenly distributed around the circumference. The upper end of the rotating mounting seat 2 is located between the second fixed fitting hole 5 and the outer cylindrical surface of the rotating mounting seat 2 and is provided with a second positioning and stabilizing fitting boss 7 that is evenly distributed around the circumference. The upper ends of the second positioning and stabilizing fitting boss 7 and the first positioning and stabilizing fitting boss 6 are both spherical structures that can be matched with the stop groove at the matching position to provide a reliable isolation space between the upper end and the combined components, ensuring better overall ventilation during use, while meeting the lubrication fluid delivery requirements, providing reliable lubrication safety during use, and better overall durability during use. It provides a rotating structure at the end of the existing stainless steel bar, which can be flexibly installed and matched during installation, so that it can be firmly and conveniently connected to the rotating power component, ensuring better rotational stability of the bar body during use, and the space occupied by the fastening installation position is relatively small, the efficiency of installation is higher, and the disassembly and assembly operation during later maintenance is also relatively convenient.
[0021] Preferably, the second positioning stabilizing mating boss 7 and the first positioning stabilizing mating boss 6 have the same height, which makes their production and processing more convenient and the combined stability during mating is more reliable.
[0022] Preferably, the second positioning stabilizing mating boss 7 and the first positioning stabilizing mating boss 6 are staggered and evenly distributed on the inner and outer sides of the circumference, so that the strength of the overall structure is better and the mating safety during use can be further improved.
[0023] Preferably, the outer side of the lower end of the rotating mounting fitting seat 2 is provided with an integral fastening spare fitting safety groove opening outward, which can make the overall structure have better heat resistance during use as needed, and if the lower end position is tightly combined with the fitting structure, the fitting position can have a certain ventilation space, which can ensure safety during use and better durability.
[0024] Preferably, the rotatable mounting seat 2 and the stainless steel bar main structure 1 are connected together by welding, so that the production cost of the overall structure is lower.
[0025] 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 described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
