The application discloses a watch and an assembling method, and belongs to the technical field of watches, wherein the watch comprises a bezel mechanism and an ear mechanism, the bezel mechanism is provided with a first watchband seat, the ear mechanism is provided with a second watchband seat and a supporting seat, the second watch seat is installed in the circumferential direction of the supporting seat, a gap is formed between the second watch seat and the supporting seat, the gap is used for accommodating the first watchband seat, so that the outer wall of the first watchband seat is in abutment with the inner wall of the second watchband seat, the first watchband seat is provided with a buckle assembly, the supporting seat is provided with a positioning groove in the circumferential direction, and the positioning groove is used for accommodating the buckle assembly; the bezel mechanism is used for rotating with the ear mechanism; when the ear mechanism is installed or dismounted, only a certain torsion force needs to be applied to the bezel mechanism, the bezel mechanism is rotated relative to the ear mechanism, the first watchband seat is moved out of the gap, and the buckle assembly is separated from the positioning groove; so that the bezel mechanism is separated from the ear mechanism, and the ear mechanism can be quickly installed or dismounted.

The utility model provides a kind of distribution box filtering cooling system, it includes cabinet, multiple mutually isolated function compartments are equipped in cabinet, at least one air filter compartment is equipped.Air filter compartment top is equipped with air outlet, bottom is equipped with air inlet, fan is equipped at air outlet, and filter assembly is equipped in compartment along vertical direction.Adjacent function compartment partition is opened with airflow exchange hole, air inlet, filter assembly, airflow exchange hole and air outlet are sequentially communicated, form airflow passage through multiple function compartments, fan is located at the end of passage and drives airflow circulation.External air enters from bottom air inlet, and after multistage filtration, it becomes clean airflow, flows through each function compartment and carries away heat, is discharged by top fan, forms forced circulation.The scheme compared with tradition, can improve heat dissipation efficiency by directional airflow, avoid heat accumulation, and multilayer filtration can block dust, has excellent dustproof performance while high-efficiency heat dissipation, applicable to the working environment of much dust.
