Technical Field
[0001] This utility model relates to the field of lock tongue technology, specifically a lock tongue with a riveted connection. Background Technology
[0002] The latch, as the name suggests, is the part of a lock that protrudes and locks against the door frame. It is usually made of metal and works by engaging with a keyhole on the door frame to lock or unlock. There are various types of latches, the most common being the beveled latch. It has one flat side and one beveled side, allowing the bevel to indicate the direction of opening. The beveled latch design is simple and easy to operate, and it is more commonly found in everyday door locks. Its advantage is that the latch automatically resets when locking, making it convenient to use; its disadvantage is that it is prone to accidental operation and can be easily pried open.
[0003] Existing lock tongue structures are usually made using alloy die casting technology and are typically solid components. This production method results in high costs for the lock tongue, which is not conducive to reducing the overall price of the finished lock. At the same time, since die-cast alloy lock tongues are usually solid components, it is difficult to conveniently design other structures inside them, such as anti-pry structures, which has certain limitations and processing difficulties. Therefore, in order to address the above problems, a riveted connection lock tongue is proposed. Utility Model Content
