The intelligent assembling and locking device comprises a driving motor (4) fixedly connected with a base frame, a driving screw rod (41) which is in power connection with the driving motor (4), a left assembling component (100) and a right assembling component (200) which are driven by two sections of threads with different screwing directions on the driving screw rod (41) respectively and a guide rail component (3) which is fixedly connected with the base frame and is used for guiding the left assembling component (100) and the right assembling component (200), wherein the left assembling component (100) and the right assembling component (200) are arranged in a laterally symmetrical manner.

The storage chamber for secondary material applicable to the discharging direction of contents stored in the container consists of body with storage space and inseparable operating section mounted around the globe. If above operating section moves up, opening and closing hole made or formed in the storage space of storage is opened and contents stored in the storage space is dropped and mixed with contents stored in the container. The mixed contents are discharged via a vent mounted on the top of operating section. A vent is not opened until the operating section is opened, and closing section of opening and closing hole is provided so that the opening and closing hole may not be not clogged after being opened.

The invention discloses an installation locking device used for a circuit board and with vibration reducing and speed adjusting functions. The device comprises a driving motor (4) fixedly connected with a base frame, a driving screw rod (41) in power connection with the driving motor (4), a left installation component (100) and a right installation component (200) respectively driven by two sections of threads with opposite rotating directions on the driving screw rod (41), and a guide rail piece (3) fixedly connected with the base frame and used for guiding the left installation component (100) and the right installation component (200), wherein the left installation component (100) and the right installation component (200) are arranged in a left-right symmetry manner.

The invention discloses a closestool cover plate descent control device which comprises a rotating shaft, a blade and a shaft sleeve. A radial end face is formed at one end of the rotating shaft and provided with an oil groove, an oil inlet of the oil groove is large, the tail end of the oil groove is small, and a rib is convexly arranged on the rotating shaft in the axial direction. A shaft cavity is formed in the blade in the axial direction, an insertion groove is integrally convexly formed in the side wall of the shaft cavity, the shaft cavity of the blade is in sleeved connection with the rotating shaft, the rib of the rotating shaft is inserted in the insertion groove of the blade, and a plurality of oil grooves are formed in the side walls of the two sides of the insertion grooves at intervals. The shaft sleeve is in sleeved connection with the rotating shaft, and a sealed cavity is formed between the shaft sleeve and the rotating shaft and filled with damping oil. When the shaft sleeve rotates, the damping oil drives the blade to rotate relative to the rotating shaft, the rib of the rotating shaft seals the oil holes, and the damping oil flows towards the oil grooves; when the shaft sleeve rotates in the opposite direction, the damping oil drives the blade to rotate n the reverse direction relative to the rotating shaft, the rib of the rotating shaft opens the oil holes, and the damping oil passes the oil holes. The closestool cover plate descent control device has reliability in opening and closing and is simple to assemble and simple in manufacturing process.
