The utility model belongs to the technical field of automobile parts, disclose a new type of sliding door locking actuator mechanism assembly, it includes base and the cover board that cooperates with base, still includes setting on the base drive mechanism, support subassembly and lock tongue, support subassembly is fixed on the base, lock tongue slidingly connected on support subassembly, drive mechanism cooperates with lock tongue, and drives lock tongue to move on drive mechanism and realizes locking or unlocking, still be equipped with the noise reduction spare of lock tongue adaptation on the base. The utility model's noise reduction spare can reduce the noise, and the use comfort is good, and the emergency unlocking structure can be in outside through corresponding tool and emergency unlocking structure cooperation realizes manual unlocking, and the overall practicality is strong, the symmetrical layout of wheel system and lock tongue can reduce production cost, simplify production management, improve assembly efficiency and strengthen product versatility, set up waterproof adhesive tape in the end outer periphery of the shaft exposure base and cover board to prevent the internal component, further strengthened the practicality of use.

The utility model discloses a spectrometer. The spectrometer comprises a shell, an interferometer module, an out-of-cabin front light path element, an out-of-cabin rear light path element and a detector module. The shell comprises a core bin and a functional bin which are sealed and isolated, an interferometer module is arranged in the core bin, and an out-bin front light path element, an out-bin rear light path element and a detector module are arranged in the functional bin. The out-of-bin front light path element emits light from a light source into the core bin, and the interferometer module receives the light from the out-of-bin front light path element; and emergent light of the interferometer module is emitted out of the core bin and is emitted to the detector module through the rear light path element outside the core bin. Therefore, related elements are located in the functional bin and the core bin respectively, the functional bin is isolated from the core bin, impurities (such as dust) are prevented from being exchanged between the functional bin and the core bin, the waterproof and dustproof effects are achieved, and the impurities cannot affect optical elements in the core bin and the functional bin.

The adapter box with the waterproof structure comprises a shell and a sealing cover, the shell is provided with an inner cavity with an opening, a sealing ring is arranged on the shell and surrounds the edge of the opening, and the shell and the sealing cover are fixedly connected through a fastening assembly so that the sealing ring can be tightly attached to the position between the shell and the sealing cover. The fastening assembly comprises a plurality of connecting columns fixedly arranged in the inner cavity and fixing pieces correspondingly matched with the connecting columns, the connecting columns are provided with first matching holes, the sealing cover is provided with second matching holes, and waterproof rings are arranged between the first matching holes and the second matching holes. When the fixing piece penetrates through the first matching hole, the waterproof ring and the second matching hole and then is locked, the waterproof ring is tightly attached between the connecting column and the sealing cover, and the waterproof ring can play a role in sealing the first matching hole or / and the second matching hole, so that the inner cavity has waterproof and dustproof functions.
