[0020] like Figures 1 to 7As shown, a safety sealing assembly includes a cylindrical main body fastening connection column 1, and the upper end of the main body fastening connection column 1 is provided with a cylindrical matching stop connection column 2 that is integrally formed and has the same central axis, which constitutes the main body of the assembly. The center position of the upper end of the matching stop connection column 2 is provided with a cylindrical main body fastening connection hole 3 that passes through the lower end surface of the whole. The inner cylindrical surface of the main body fastening connection hole 3 is provided with an internal fastening thread groove, through which an internal fastening connection can be performed. The upper end of the main body fastening connection hole 3 is provided with a cylindrical sealing matching stop groove 4, which can ensure a better fit tightness at the internal upper end position when the assembly is performed. It can be combined with the matching component in a stop position. The outer cylindrical surface of the main body fastening connection column 1 is provided with a spare fastening thread groove, which can be fastened and matched through the outer fastening thread groove, and can realize a bolt-like fastening connection. The outer cylindrical surface of the main body fastening connection column 1 is provided with sealing anti-slip safety grooves 5 that are evenly distributed around the circumference and communicate with the main body fastening connection hole 3. During fastening, the outer side can cooperate with the sealing ring for connection. During fastening, the sealing ring can be pressed into this position, which can limit the assembly of the sealing ring and prevent the sealing ring from shifting or falling off during later use. The outer side of the sealing anti-slip safety groove 5 is larger than the side near the main body fastening connection hole 3, making the press-in operation when the outer side is engaged more convenient and having a relatively small impact on the strength of the main body structure. It can ensure the sealing performance of the inner position by arranging a sealing stop groove at the upper end of the main structure, and can ensure the sealing performance of the inner position by arranging a sealing anti-slip safety groove which is circumferentially distributed and communicated with the inside at the outer position. When tightening, the sealing ring can be pressed into this position, so that the sealing ring can be limited in position during the tightening process to prevent deviation or falling off during use after tightening. The fitting is tighter during use, and the overall connection position has stronger durability. The threaded grooves arranged on the inside and outside can meet the fitting requirements of various tightening positions, and have a wider range of applications when used.

[0021] Preferably, the cross-section of the sealing anti-slip safety groove 5 is an isosceles triangle structure, which can reduce the impact of this position on the strength of the main structure, increase the connection bearing capacity when the whole is matched, and improve safety during use.

[0022] Preferably, the lower end of the main body fastening connection hole 3 is provided with a matching guide connection groove for convenient assembly, ensuring that the internal connection operation during fastening assembly is more convenient and the matching efficiency during assembly is higher.

[0023] Preferably, a fastening clamping plane 6 is provided at the front and rear positions of the mating stop connecting column 2, so that the whole can cooperate with the clamping tool to perform the fastening operation when fastening, making the overall fastening safer and more reliable.

[0024] Preferably, the upper edge of the sealing and fitting stop groove 4 is provided with a chamfered structure for convenient installation and assembly, which is more convenient during assembly and assembly, has a fitting guide function, and can improve the fitting efficiency during assembly.

[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.
