The utility model provides a kind of dustproof device for decoration hole, it is related to decoration tool technical field, the dustproof device for decoration hole includes supporting member and sheltering member, the supporting member is limited to part, the bottom surface of the limiting part and the top surface of decoration board are in abutment;The sheltering member is connected with the supporting member, the sheltering member is compatible with the decoration hole on the decoration board, for the sheltering of the decoration hole;The utility model is cooperated by supporting member and sheltering member, not only firm installation, strong anti-interference ability, but also can guarantee close fitting when using, dustproof effect is remarkable, while simple structure, convenient operation, adaptive flexible, strong versatility.

The invention discloses a radiation protection device for a CT examiner, and relates to the technical field of medical radiation protection equipment, the radiation protection device comprises a bottom plate and a radiator mounted at the top of the bottom plate, and the top of the bottom plate is provided with an examination moving mechanism. According to the radiation protection device for the CT examiner, by arranging the telescopic shielding adjusting mechanism, flexible adjustment of the covering range of a shielding area is achieved, the combined covering area of the first lead cloth and the second lead cloth can be accurately adjusted, it is ensured that sensitive organs are completely shielded, meanwhile, an examined part is prevented from being shielded, and the examination efficiency is improved. The problems that when an existing device is used, the size of a thyroid gland shielding part and the size of a gonad shielding part are fixed, due to body type differences of different crowds, thyroid gland and gonad positions and coverage ranges of adults and children and males and females are obviously different, sensitive organs are difficult to completely cover by the shielding parts with the fixed sizes, and the sensitive organs cannot be completely covered by the shielding parts with the fixed sizes are solved. And the protection effect and the diagnosis accuracy are influenced.

This utility model discloses a dustproof HDMI cable connector, belonging to the technical field of HDMI cable connectors. It includes a connector head, one end of which has a connecting wire, and the other end of which has a connecting terminal. A mounting plate is fixed to the end of the connecting terminal near the connector head. It also includes an adjustment mechanism disposed between the mounting plate and the connector head. The adjustment mechanism is used to adjust the retraction and extension of the connecting terminal. A through groove is formed at the end of the connector head away from the connecting wire, and the extended connecting terminal passes through the through groove. A dustproof component is provided inside the through groove to prevent dust from entering when the connecting terminal is retracted or extended. This dustproof HDMI cable connector has good dustproof performance. The connecting terminal can extend outside the connector head during use and can be retracted inside the connector head when not in use, avoiding direct exposure to the outside and preventing dust from entering. This improves the stability of signal transmission during subsequent connections.

This utility model relates to the field of non-magnetic pipe cutting devices, and more particularly to a non-magnetic pipe cutting device with a protective mechanism. The device includes a cutting device body, a cutting unit, and a protective cover. An auxiliary protective component is fitted onto the outside of the protective cover, and the auxiliary protective component is connected to the protective cover via an installation component. In this utility model, the protective cover provides basic protection. Simultaneously, the extension protrusion driven by the spring body continuously pushes one end of the telescopic protective cover to adhere to the outer wall of the non-magnetic pipe to be cut. This facilitates active and dynamic adhesion to the outer walls of pipes of different diameters within a certain range, ensuring that the cutting device body shields the rapidly rotating cutting disc or flying pipe debris during the cutting process.
