This application provides a chemical mechanical polishing pad mounting device, including a base, with a mounting part at one end of the base. The mounting part includes a bottom wall and a surrounding wall circumferentially surrounding the bottom wall. The surrounding wall and the bottom wall form a mounting groove. An alignment mechanism is provided on the surrounding wall. The mounting groove and the alignment mechanism are configured to achieve axial centering and positioning of the ceramic disc and the wax-free adsorption pad, thereby effectively improving the alignment accuracy between the wax-free adsorption pad and the ceramic disc, enabling the wax-free adsorption pad to accurately adhere to the ceramic disc, improving the bonding success rate, reducing the risk of material waste, and the chemical mechanical polishing pad mounting device of this application greatly simplifies the process structure and reduces costs.

The embodiment of the utility model provides a door lock. The door lock comprises a first elastic piece, a sliding assembly, a locking assembly and a shell. Wherein the locking assembly comprises a locked piece and a locking piece, and the locked piece and the locking piece are in locking fit; a containing space is formed in the shell, the sliding assembly, the locking piece and the first elastic piece are arranged in the containing space, and the locking piece is fixed to the shell in a rotating mode. The first elastic piece is used for abutting against the locking piece, and the locked piece can move in the sliding direction of the sliding assembly so as to drive the locking piece to rotate. The door lock has an opening state and a locking state, in the locking state, the locking piece is matched with the locked piece in a locking mode, and the first elastic piece abuts against the locking piece, so that the locking piece is kept in the locking matching state with the locked piece. According to the door lock, manual locking can be achieved, the door lock cannot be opened from the outside easily after being locked, and meanwhile the door lock is reasonable and simple in technological structure, low in manufacturing cost, low in installation and warranty cost and high in safety.
