This invention belongs to the field of orthodontic instrument technology, specifically a periodontal targeted near-infrared light bimaxillary therapy device that protects tooth crowns. It includes a protective brace and a bimaxillary irradiation device. The protective brace includes a maxillary protective brace and a mandibular protective brace, each comprising a lingual plate and a labial plate. The labial plate includes a cervical sleeve and a receiving groove. The bimaxillary irradiation device includes an outer irradiation plate, an inner irradiation plate, and a flexible occlusal plate. Near-infrared laser lamps are installed on the outer and inner irradiation plates. This invention achieves simultaneous irradiation of the labial and lingual periodontal tissues of both jaws, significantly improving orthodontic efficiency. It can simultaneously irradiate the entire periodontal area of ​​both jaws in a single treatment, eliminating the need for separate upper and lower jaw procedures, shortening treatment time, achieving simultaneous activation of all periodontal tissues, and improving tooth movement efficiency. The bimaxillary irradiation device uses precise lamp placement according to the periodontal ligament area, working in conjunction with the protective brace to fully cover the protective crown, synergistically avoiding thermal and light damage.

The utility model belongs to the technical field of engineering machinery accessories, and particularly discloses a safety locking mechanism of an engineering machinery seat, which comprises a cab mounting plate, a safety locking rod, a fixed support and a gas spring, the fixed support is fixedly connected to the cab mounting plate, and the safety locking rod is hinged to the fixed support; the safety locking rod is in a U shape, and the two sides of the safety locking rod are bent in an L shape. One end of the gas spring is hinged to the fixing support, the other end of the gas spring is hinged to the safety locking rod, and the safety locking rod achieves switching between a downward turning working state and an upward turning shutdown state through the gas spring. The safety locking rod comprises a framework and a protection pad, the framework is wrapped with the protection pad, the safety locking rod is turned upwards before use, when the safety locking rod is used, a person enters the inner side of the safety locking rod and is turned downwards to a downward turning working state, the safety locking rod encloses the person and provides safety protection, and the protection pad provides flexible support for the human body. And the fatigue feeling caused by long-time operation of the whole machine is relieved.
