Description

Technical Field

[0001] The utility model relates to a dust cover for a plane lock, in particular to a sliding dust cover for a plane lock handle. Background Art

[0002] A flat lock is a lock that is applied to metal cabinet doors and whose top is integrated with the cabinet door surface after installation. Some of these flat locks are equipped with a pop-up handle. When the handle is turned, the steel bolt at the bottom of the base is driven to rotate through the shaft inside the base, thereby achieving opening and closing. The lock core of some of these flat locks is generally equipped with a dust cover, which is higher than the handle plane or locked with screws, which is neither beautiful nor convenient. Some of the dust covers of the gourd locks currently on the market are not only unsightly in appearance, but also have the risk of scratching the paint on the handle when it is rotated to open, and affect the grip of the handle. In addition, the dust covers of some similar locks are rotated open or closed by magnets, such as the application number 202022305007.8 disclosed in the Chinese patent literature, the authorization announcement date 2021.09.07, and the utility model name "lock core with dust cover"; the positioning assembly of the lock core includes a magnet and an iron block, the magnet is arranged on one of the dust cover or the lock core seat, and the iron block is arranged on the other of the dust cover or the lock core seat; the magnet can attract the iron block to limit the rotation of the dust cover relative to the lock core seat. However, the magnet structure at the dust cover of the above-mentioned product is realized by the rotation of the dust cover, not by the sliding of the dust cover; and the existing similar products rarely use the method of setting a sliding cover at the bottom of the dust cover to expose or close the keyhole of the dust cover, and lack the fixed structure design after the sliding cover slides, which easily causes serious scratches on the components during repeated use. Summary of the invention
