DETAILED DESCRIPTION

[0020] like Figures 1 to 7As shown, a transmission shaft assembly safety component comprises a cylindrical main assembly stop column 1, an integral cylindrical first assembly connection column 2 is provided at the center position of the upper end of the main assembly stop column 1, and an integral cylindrical second assembly connection column 3 is provided at the lower end of the main assembly stop column 1. They are main structures that cooperate with transmission shafts of different specifications when combined, and can replace the existing multiple combinations of mutually tightened connection and matching installation. Thus, the structural strength and matching accuracy of the installation position can be effectively guaranteed. A avoidance matching chamfering structure is provided at the outer position of the upper end of the first combination connection column 2, and a cylindrical first matching stop groove 4 is provided at the center position of the upper end of the first combination connection column 2, which can be matched and connected with the transmission shaft at the upper end. An inverted conical main body isolation matching groove 5 is provided at the lower end of the first matching stop groove 4 to ensure that there is a reliable isolation space between the lower end installation position and the upper end installation position. A ventilation avoidance matching groove 6 is provided on the left and right sides of the upper end of the first matching stop groove 4, respectively, so that when the upper end matching shaft is in use, the matching position has a reliable ventilation space, ensuring better heat resistance during use. The inner side of the ventilation avoidance matching groove 6 is an inclined slope structure, which makes the space at this position larger and the ventilation effect better. The ventilation avoidance matching groove 6 penetrates the outer side of the first matching stop groove 4. The lower end of the main body isolation matching groove 5 is provided with a cylindrical main body installation combination hole 7 that penetrates the lower end surface of the whole. It is the main body matching position that cooperates with the transmission shaft of another size at the lower end during assembly. A circle of cylindrical lubrication safety matching grooves 8 are provided at the connection position between the outer side of the second combination connecting column 3 and the main body assembly stop column 1, and the outer position can be matched and connected with the lubrication component. The outer side of the lubrication safety matching groove 8 is provided with a main body lubrication delivery hole 9 that is evenly distributed around the circumference and communicates with the main body installation combination hole 7, which can make the lubricating liquid more evenly delivered to the movable position of the internal transmission shaft, ensuring better transmission stability during use. When in use, it can simultaneously meet the requirements of two transmission shafts with different diameters for fitting and installation. By arranging a conical isolation fitting groove at the center fitting position, it can ensure that the heat impact between each other during use is smaller, and by arranging ventilation avoidance fitting grooves and main body lubrication delivery holes at different positions, the transmission shafts at different positions can be lubricated and ventilated respectively during use, ensuring that the transmission shaft is safer and more durable during use.

[0021] Preferably, the diameter of the second combined connecting column 3 is the same as the diameter of the first combined connecting column 2, so that the structural stability of the upper and lower matching positions is better, the structural safety during use is higher, and the durability can be further improved.

[0022] Preferably, the upper end of the ventilation avoidance groove 6 is parallel to the upper end surface of the first combined connecting column 2, so that the space at the upper end is larger and the upper end side position can more efficiently ventilate the internally mating transmission shaft when in use.

[0023] Preferably, a lubrication delivery guide matching groove is provided on the outer side of the main body lubrication delivery hole 9, so that the lubrication liquid on the outer side can flow more quickly to the inside, thereby improving the lubrication smoothness of the internal movable position.

[0024] Preferably, the main body assembly stop column 1 is provided with an integral fastening combination installation matching groove, which can be fastened and matched during the overall installation as required.

[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 of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
