Locking device for cover body, upper cover structure of laundry equipment and laundry equipment

Abstract

The invention relates to the field of laundry equipment, and discloses a locking device for a cover body, an upper cover structure of the laundry equipment, and the laundry equipment. The locking device includes a rotating shaft part and a supporting part, wherein: the rotating shaft part includes a shaft rod (2), the ratchet (3) and the ratchet (4) matched with the ratchet (3), the shaft (2) is rotatably mounted on the support part, the ratchet (3) is fixed Connected to the shaft (2), the ratchet member (4) is rotatably mounted on the support portion so that the ratchet member (4) can be engaged with the ratchet (3) at an engaging position And switch between the disengaged position disengaged from the ratchet (3), in the engaged position, the pawl member (4) can only rotate around the axis of the shaft (2) in the first direction. The locking device provided by the present application can prevent accidental opening of the cover body, has high stability and low failure rate.

Description

technical field [0001] The invention relates to the field of laundry equipment, in particular to a locking device for a cover, an upper cover structure of the laundry equipment, and the laundry equipment. Background technique [0002] When the dehydration bucket of the top-opening washing machine rotates at high speed, such as during the drying and dehydration process, the upper cover needs to be locked to prevent the upper cover from being accidentally opened. At present, the commonly used locking structure of the top-opening type washing machine is an electromagnetically driven latch structure. A door hook is arranged on the cover plate, and the door cover is locked by inserting the latch into the door hook. This kind of locking structure needs to set a hole on the workbench to match the door hook, which is likely to cause electrical failure due to water seepage; and because once the latch and door hook are misaligned, the door cover cannot be locked, resulting in a higher...
