The utility model discloses a combined sealing flange, which relates to the technical field of flange combination, aims to solve the technical problems that the sealing performance of two connected flanges is influenced and leakage is easily caused by the influence of the vibration of a pipeline at present, and comprises a first flange main body and a second flange main body, connecting grooves are formed in the opposite faces of the first flange body and the second flange body, a sealing part is connected between the connecting grooves in the two sides in a clamped mode, and the sealing part is arranged in one connecting groove through a sealing piece with a plurality of first arc-shaped faces and a plurality of second arc-shaped faces and abuts against the other connecting groove in the assembling process. The first flange body and the second flange body are sealed when being extruded, and gaps in the connecting grooves are filled with the first clamping corners and the second clamping corners when being extruded. The utility model has the advantages that the installation position of the sealing element is stable, the sealing element is not easy to fall off in the assembly process, the position can be kept fixed during fixed combination, and the connection sealing performance is improved.

The utility model relates to an elastic assembly and a printer, the elastic assembly comprises an installation part and an elastic part, the installation part comprises a first installation sheet and a second installation sheet, the first installation sheet and the second installation sheet are arranged in parallel and at an interval along a first direction, and the elastic part is arranged between the first installation sheet and the second installation sheet. The elastic component is provided with a compression channel penetrating in the second direction, and the second direction is perpendicular to the first direction. According to the elastic assembly and the printer, the first installation piece and the second installation piece which are arranged in parallel in the first direction make contact with the ink box and the printer correspondingly, the contact area between the elastic assembly and the ink box and the contact area between the elastic assembly and the printer can be large, and then the stability of the elastic assembly between the ink box and the printer is improved; the elastic component is provided with the compression channel penetrating in the second direction, so that a large compression space can be formed between the first mounting piece and the second mounting piece, and the elastic component can provide good elastic force for the ink box.

This utility model discloses a one-way clutch with spring protection, including a clutch, a drive shaft, a gear, a spring limit seat, and a tower-shaped spring. Rollers and an integrally formed double roller spring are installed in the wedge-shaped groove of the clutch outer ring to prevent jamming caused by drive shaft oscillation; the gear achieves buffered engagement through the tower-shaped spring and the limit groove. This design effectively reduces the risk of gear damage and improves the reliability of the clutch operation.
