The invention relates to an elevator car door lock device and an elevator. The elevator car door lock device comprises a belt, a door vane base, a first oscillating bar, a second oscillating bar, a horizontal crossbar, a telescopic device and a car door lock hook. The belt is connected with the first oscillating bar, and the first oscillating bar and the second oscillating bar are connected to the door knife base in a rotating mode. One end of the horizontal crossbar is connected with the car door lock hook, and the other end of the horizontal crossbar is provided with a protruding block. The protruding block abuts against one side, far from the first oscillating bar, of the second oscillating bar. The telescopic device comprises an energized magnet, a connection rod, a limit plate, a push plate and a telescopic spring, wherein the telescopic spring is arranged on the connection rod in a sleeving mode. The second oscillating bar is provided with a through hole matched with the connection rod, one end of the connection rod is connected with the limit plate, and the other end of the connection rod penetrates through the through hole and is connected with the push plate. The two ends of the telescopic spring abut against the push plate and the face, opposite to first oscillating bar, of the second oscillating bar respectively. According to the elevator car door lock device, the stroke difference between a landing door and a car door is greatly reduced, synchronicity between the landing door and the car door is improved, the length of an upper sill of the car door is greatly reduced, and an elevator well can be designed to be narrower.

The invention relates to the field of shipbuilding tooling, in particular to a method for designing a curved anchor mouth. The method is based on an ideal anchor adhesion type to redesign the shape ofthe anchor mouth and the installation angle thereof, so that the problem that when a wooden mold cat anchor test enters a final link, the test fails due to poor anchorage device adhesion is solved, awooden mold cat anchor test project only needs to focus on the cast anchor smoothness, the disturbance of complexity of an anchor adhesion test project is avoided, a cat anchor experiment site load is alleviated, and the test cycle is shortened.

The invention provides a driving mechanism, a pot cover component and a cooking appliance. The driving mechanism comprises an operating portion and a lever portion, wherein the lever portion is movably connected with an installing base and is arranged to drive the lever portion. The lever portion is provided with an initial position, a first position, a first working position and a second working position and can move from the initial position to the first position in the first direction and move from the first working position to the second working position in the second direction opposite to the first direction, the lever portion can move from the initial position to the second working position in the third direction, and the first direction and the third direction form an included angle. A lever is driven through the operating portion, so that the lever portion can have multiple working positions in difference directions. Due to the fact that the driving mechanism only comprises the operating portion and the lever portion, so that the driving mechanism is simple in structure and does not cause part redundancy, and the phenomenon that a driving mechanism in the prior art is easily stuck is effectively avoided.

The invention relates to a device for laying decorative wall tiles for indoor decoration, which includes a moving device, two side plates, a feeding device, a laying device and a plastering device. The welding method is equipped with a feeding device, a laying device is installed under the feeding device, the laying device is installed inside the side plate, and a plastering device is installed at the left end of the laying device. The present invention provides a device for laying decorative wall tiles for interior decoration, which can solve the problem of manual laying, first manually smearing cement on the rough surface of the wall tiles, and then manually positioning and laying the wall tiles. When laying an indoor wall tile laying device, first manually place the wall tiles on the wall tile laying device to lock and fix them, and then apply cement to the rough surface of the wall tiles. Due to the uneven application of cement during laying, the wall tiles are laid unevenly. Hollow, and the process of manually placing wall tiles is cumbersome, thereby reducing the efficiency of wall tile laying and other issues.
