Introduction to the D-Latch/ Hinge

#### I. Definitions
A latch is a device used to fix the door leaf and prevent it from being accidentally opened or closed. It is usually installed on the side or bottom of the door and fixed to the door frame by mechanical means. The design and function of the latch can vary according to different application scenarios and requirements.

#### 2. Structural characteristics
1. "Main part
The main part of the latch is its primary structural component, usually made of metal (such as stainless steel, aluminum alloy, iron, etc.) or plastic. Metal latches have higher strength and durability, while plastic latches are lighter and less costly.
2. ** Lock tongue or latch **
The lock tongue or latch is a key component of the door latch, which is used to insert into the holes or slots on the door frame to fix the door leaf. The lock tongue can be either movable or fixed, and the specific design depends on the type of latch.
3. ** Connecting components **
The connecting component is used to fix the latch to the door leaf. Common connecting components include screws, nuts, rivets, etc. These components need to ensure that the latch is firmly installed on the door to prevent loosening or falling off.
4. ** Operating components **
The operating component is used to control the opening and closing of the latch. Common operating components include knobs, handles, buttons, etc. The design of these components needs to be convenient for users to operate and be able to provide sufficient feedback to let users know whether the latch has been correctly locked or opened.

3. Classified by function
- ** Ordinary latch ** : It is used for general doors and provides basic fixing functions.
- ** Safety latch ** : It is used for anti-theft doors and other doors that require high security, featuring stronger anti-picking ability and higher strength.
- ** Decorative latch ** : Mainly used for decorative purposes, such as in ancient buildings or doors with special designs. Decorative latches usually have exquisite appearances and unique designs.

The latch can effectively prevent the door from being accidentally opened, providing additional security. Especially for anti-theft doors and some doors that require high security, the latch is an indispensable component.
2. Easy to operate
The operating components of the latch are reasonably designed, allowing users to easily lock or open the door. Some latches also have an automatic locking function, further enhancing the convenience of use.
3. Strong durability
Metal latches have high strength and durability, and can withstand frequent use and certain external force impacts. It can maintain good performance even in harsh environments.
4. Low cost
