1. Field of the Invention

The present invention relates to a rotating seat for a stamp, and more particularly to a rotating seat that improves the adjusting convenience of making the type band flush with a pad, the evenness of ink stained on the pad, and the clearness of a stamped pattern.

2. Description of Related Art

With reference to Fig. 11, a conventional rotating seat of a stamp has a first supporting frame 90, a second supporting frame 91, a printing assembly 92, and two screws 93. The second supporting frame 91 is mounted on the first supporting frame 90. The printing assembly 92 is mounted on the second supporting frame 91. A type band of the printing assembly 92 extends out of a bottom surface of the first supporting frame 90. The two screws 93 are respectively mounted on two ends of the second supporting frame 91. Each screw 93 is inserted through the second supporting frame 91, and is screwed into the first supporting frame 90 for fixing the second supporting frame 91 on the first supporting frame 90.
The conventional rotating seat of the stamp is rotatably mounted in a shell. The shell has a fixing seat and a moving seat. The moving seat is mounted on the fixing seat and may move upwardly and downwardly for driving the conventional rotating seat to rotate and move upwardly and downwardly. A pad 94 is mounted on the bottom surface of the first supporting frame 90. The two screws 93 may be adjusted by users for moving the second supporting frame 91 relative to the first supporting frame 90. The printing assembly 92 is moved with the second supporting frame 91 for making the type band of the printing assembly 92 flush with a printing surface of the pad 94.
However, the second supporting frame 91 is fixed on the first supporting frame 90 by the two screws 93. The printing assembly 92 can be printed on a sheet of paper to form a pattern on the paper. If the type band of the printing assembly 92 is not adjusted well, the stamped pattern is not clear. The type band of the printing assembly 92 is adjusted by the two screws 93. It is hard to judge whether the type band of the printing assembly 92 is flush with the printing surface of the pad 94 or not. It is hard to judge whether adjusting degrees of the two screws 93 are same or not. If the type band of the printing assembly 92 is not flush with the printing surface of the pad 94, the stamped pattern is not clear. If the adjusting degrees of the two screws 93 are different, the type band of the printing assembly 92 may be slanted, and then ink stained on the type band is not distributed evenly, which also makes the stamped pattern unclear.
To overcome the shortcomings, the present invention provides a rotating seat to mitigate or obviate the aforementioned problems.
The objective of the invention is to provide a rotating seat to resolve the problems that the adjustment of the type band is not convenient and the type band is slanted easily after adjustment.
The rotating seat has a first supporting frame, a second supporting frame, a printing assembly, an adjusting member, and two auxiliary members.

The insertion slot is formed between the carrier board and the flange. The two recesses are respectively formed on the two ends of the first supporting frame. The two first retaining surfaces are respectively formed in the two ends of the first supporting frame and are respectively connected to the two recesses of the first supporting frame.
The second supporting frame is moveably mounted on the first supporting frame and has a side, two ends, a main rod, a threaded hole, and two second retaining surfaces. The main rod is mounted on the side of the second supporting frame. The threaded hole is formed through the main rod and faces the insertion slot of the assembling member. The two second retaining surfaces are respectively formed in the two ends of the second supporting frame, and respectively face the two first retaining surfaces of the first supporting frame.
The printing assembly is mounted on the second supporting frame and has a type band extending out of the bottom surface of the first supporting frame.
The adjusting member is disposed on the assembling member of the first supporting frame and is inserted into the threaded hole of the second supporting frame. The adjusting member has a bottom plate, a threaded shank, and a working slot. The bottom plate is inserted into the insertion slot of the assembling member and has a top surface. The threaded shank is formed on the top surface of the bottom plate, is inserted into and engaging with the threaded hole of the second supporting frame, and has a top surface. The working slot is formed on the top surface of the threaded shank.
The two auxiliary members are respectively inserted into the two recesses of the first supporting frame. Each auxiliary member has two ends respectively abutting a corresponding one of the first retaining surfaces and a corresponding one of the second retaining surfaces.
Furthermore, the rotating seat has a pad mounted on the bottom surface of the first supporting frame. The second supporting frame has an auxiliary rod mounted on another side of the second supporting frame and being opposite the main rod. The two auxiliary members are both springs and are both mounted uprightly between the first supporting frame and the second supporting frame. In addition, the working slot of the adjusting member is 1-shaped.
The rotating seat is rotatably mounted on a shell for moving upwardly and downwardly relative to the stamp. The adjusting member can be rotated for adjusting the second supporting frame to move upwardly and downwardly. The printing assembly is mounted on and is coacted with the second supporting frame. The printing assembly can be adjusted by the movement of the second supporting frame. The outstanding height of the type band relative to the first supporting frame is easily adjusted to make the type band flush with the pad. Furthermore, the auxiliary members could help cushion for eliminating a flushed error between the type band and the pad.
In use, a base surface is formed by three points with the adjusting member and the two auxiliary members. The two auxiliary members could be suitably deformed for eliminating the slanted error. The type band and the pad are inked simultaneously and evenly, and then the type band and the pad accurately abut a sheet of paper to stamp and form a pattern on the paper. The stability of the rotating seat, the uniformity of the stamped force, the clearness of the stamped pattern, and the quality of the stamped pattern are increased
