Description

technical field [0001] The invention relates to a lock structure, in particular to a semi-enclosed safety horizontal latch. Background technique [0002] The traditional horizontal latch has the characteristics of simple structure, convenient use and easy manufacture, which make it widely exist in people's daily life, especially in the vast rural areas. However, due to the unique structure of the traditional horizontal latch, it needs a Use the padlock together. For a padlock that is completely exposed to the outside, because there is a large gap between the U-shaped shackle of the padlock and the lock body, thieves often use the flat platform at the junction of the U-shaped lock shackle and the lock body. Under force, use a crowbar and other criminal tools to insert into the gap, and easily pry the padlock open. Certainly also some designers have designed some tamper-resistant locks, such as the safety door latch of the Chinese patent authorization announcement number CN20...

Problems solved by technology

[0002] The traditional horizontal latch has the characteristics of simple structure, convenient use and easy manufacture, which make it widely exist in people's daily life, especially in the vast rural areas. However, due to the unique structure of the traditional horizontal latch, it needs a Use padlocks together. For padlocks that are completely exposed to the outside, because there is a large gap between the U-shaped shackle of the padlock and the lock body, thieves often use the flat platform at the junction of the U-shaped lock shackle and the lock body. Under force, use a crowbar and other criminal tools to insert into the gap and easily pry the padlock open

Certainly also some designers have designed some tamper-resistant locks, such as the safety door latch of the Chinese patent authorization announcement number CN2079645U announcement, and the latch mechanism of the Chinese patent authorization announcement number CN1580475 announcement. Most of them are complex in structure and poor in safety. Meet the requirements of anti-prying
