[0018] like Figures 1 to 6As shown, a lubricating stainless steel bar comprises a cylindrical bar main structure 1, wherein the left end portion of the bar main structure 1 is provided with an integrally formed cylindrical combined mounting connection column 2 with the same central axis, and the two components form a whole. The diameter of the combined mounting connection column 2 is larger than the diameter of the bar main structure 1. The outer cylindrical surface of the combined mounting connection column 2 is provided with a lubrication matching safety groove 3 with the same central axis. The cross-section of the lubrication matching safety groove 3 is an arc-shaped structure facing outward in the opening, which provides better smoothness and a larger matching area during lubrication matching. The center position of the right end face of the bar main structure 1 is provided with a cylindrical center combined connecting hole 4 that runs through the left side of the whole, and can be inserted and matched with another shaft component. A shock-absorbing combination safety groove 5 with a square cross-section is provided on the left and right sides of the center combined connecting hole 4, respectively, which can be matched with the shock-absorbing component at both ends for matching installation, and adopts an embedded combination, so the combination position occupies less space. The internal angle position of the shock-absorbing combination safety groove 5 is provided with a cylindrical avoidance installation and matching convenient groove 6, which can make the space at the corner position larger, and can be used to match this position for the fastening combination of the two end structures as needed, so that the space occupied by the fastening position is smaller, and the stability of the overall fastening connection is more reliable. The interior of the lubrication matching safety groove 3 is provided with lubrication delivery matching holes 7 that are evenly distributed around the circumference and communicated with the central combination connection hole 4, which can achieve rapid lubrication matching between the inside and outside, ensuring more reliable lubrication safety during use. It is made by processing stainless steel bars into fine-machined products. The main structure is composed of two cylindrical structures of different diameters. During installation, the shock-absorbing combination safety groove at the end position can be used to match the shock-absorbing assembly for stable matching connection. The internal center position can be associated with the matching shaft. During use, the lubrication structure that communicates between the inside and outside can achieve smooth and uniform lubrication matching. The overall matching accuracy during use is higher, the matching stability during installation is better, the durability during later use is more guaranteed, the seismic safety is higher, and the service life is longer.

[0019] Preferably, the connection position between the combined installation connecting column 2 and the rod main structure 1 is provided with a transition fitting connecting column with an arc-shaped cross section, so that the overall structural support strength is better, the connection position is smoother, and the durability in later use can be further improved.

[0020] Preferably, the left and right shock-absorbing combination safety grooves 5 have different sizes, and can be installed in conjunction with fastening connection components of different specifications during installation, which has a wider range of applications when combined.

[0021] Preferably, a conical transition delivery matching flow groove is provided at the inner and outer sides of the lubrication delivery matching hole 7 respectively, which can make the lubrication flow efficiency at both ends higher when the lubricating liquid is matched, and the lubrication safety can be further improved.

[0022] 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.
