[0005] A stainless steel cup-mouth bolt, characterized in that it includes a main body mating fastening seat with a regular hexagonal outer side, the lower end of the main body mating fastening seat is provided with an integrally formed cylindrical fastening connection threaded column, the upper end of the main body mating fastening seat is provided with an integrally formed conical cup-mouth mating connection column, the upper end of the cup-mouth mating connection column is provided with an integrally formed inverted cone-shaped second mating connection column, the upper end of the second mating connection column is provided with an integrally formed mating connection combination column with a regular hexagonal outer side, and the outer side surface of the mating connection combination column is provided with an integrally formed spherical locking mating connection boss.

[0006] Furthermore, the outer side of the second matching connecting column is a spherical structure.

[0007] Furthermore, the projection of the locking and fitting connection boss in the up-down direction does not exceed the area of ​​the projection of the main body fitting and fastening seat in the up-down direction.

[0008] Furthermore, the locking and fitting connection boss is located at the center position of the outer side surface of the fitting connection combination column in the width direction.

[0009] Beneficial effects of the utility model:

[0010] The utility model adopts an integrally formed structure, and the upper end position adopts a cup-shaped structure design, which can ensure higher precision when the upper and lower positions are matched with different mechanical parts during safe use, better firmness of the overall connection, and higher precision of the matching during assembly. The upper end position structure is equipped with a locking matching connection boss, which can realize the insertion and engagement assembly of the upper end matching parts from top to bottom, and the combination efficiency during installation is higher and the connection strength is more reliable.

[0018] like Figures 1 to 6As shown, a stainless steel cup-mouth bolt includes a main body mating fastening seat 1 with a regular hexagonal outer side, the lower end of the main body mating fastening seat 1 is provided with an integrally formed cylindrical fastening connection threaded column 2, the upper end of the main body mating fastening seat 1 is provided with an integrally formed conical cup-mouth mating connection column 3, the upper end of the cup-mouth mating connection column 3 is provided with an integrally formed inverted cone-shaped second mating connection column 4, a cup-mouth combination mating groove is formed therebetween, which can realize the installation combination when the side is spliced ​​and mated. The upper end of the second mating connection column 4 is provided with an integrally formed mating connection combination column 5 with a regular hexagonal outer side, the outer surface of the mating connection combination column 5 is provided with an integrally formed spherical locking mating connection boss 6, which can meet the requirements of the top-down mating component for locking position connection, can play a role in locking and preventing loosening, and is firmly mated with the telescopic mating structure of the mating position. It adopts an integrated structure and a cup-shaped structure design at the upper end. When used safely, it can ensure a higher degree of accuracy when the upper and lower positions are matched with different mechanical parts, the overall connection is more firm, and the matching accuracy during combination is also higher. The upper end position structure is equipped with a snap-fit ​​connection boss, which can realize the insertion and snap-fit ​​assembly of the upper end matching parts from top to bottom, and the combination efficiency during installation is higher and the connection strength is more reliable.

[0019] Preferably, the outer side of the second mating connecting column 4 is a spherical structure, which can ensure higher structural strength, a larger combined fitting area of ​​the mating position, and better mating stability when mating at this position.

[0020] Preferably, the projection of the locking and fitting connecting boss 6 in the up and down directions does not exceed the area of ​​the projection of the main body fitting fastening seat 1 in the up and down directions, so that the space occupied by the overall structure is smaller, and after installation, the overall flatness of the upper and lower positions is also better.

[0021] Preferably, the locking and fitting connection boss 6 is located at the center position of the width direction of the outer side surface of the fitting and fitting combination column 5, so that this structure has a stronger bearing capacity during fitting and a higher fitting safety.

[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 replacements can be made without departing from the principles described in the present invention. These improvements or replacements should also be regarded as the scope of protection of the present invention.
