Description

Technical Field

[0001] The utility model belongs to the field of vacuum tube detection, in particular to a vacuum tube sealing detection device. Background Art

[0003] A Chinese patent with announcement number CN216116537U discloses a vacuum tube sealing detection device, which belongs to the technical field of vacuum tube detection devices. The key points of its technical solution are that it includes a detection device body, an air pump, and an electric telescopic rod. The vacuum tube sealing detection device has cavities at both ends of the tube groove, and a clamping block is provided in the cavity. The clamping block is made of rubber and can clamp the vacuum tube. The back of the clamping block is connected with a spring, so that vacuum tubes of different diameters can be clamped. In addition, there are multiple tube grooves and they are installed on the connecting piece. Multiple vacuum tubes can be tested instead of testing the sealing of a single vacuum tube, which greatly improves the work efficiency. The piston can be pulled out from the branch pipe and can adapt to vacuum tubes of different diameters, so that the detection device has a variety of effects. In the vacuum tube sealing detection device in the application, the clamping block elastically positions the vacuum tube through a spring. Although it can adapt to vacuum tubes of different diameters, the elastic clamping force for vacuum tubes with small diameters will also be reduced, affecting the stability of the vacuum tube clamping, and thus affecting the vacuum tube test.
