What's Each Part Name Of Door Handle Lock


Nowadays, the most commonly used door handle locks is the split door handle locks, so parts of the structure of the split door handle locks include?
Let’s learn with YALIS, the top brand of door handle. The structure of split door handle locks is generally divided into five parts: door handle, rosette & escutcheon, lock body, cylinder and spring mechanism & mounting kit. And then, we will explain it in detail.


Handle:
There are many designs and surface finishes for door handles. The raw materials of door handles on the market are roughly divided into several metals: brass, zinc alloy , aluminum alloy, stainless steel and so on. Of course, there are other non-metallic door handles, such as ceramic handles and crystal handles.
At present, the door handles in the high-end market are mainly brass handles and zinc alloy handles, the middle and high-end markets are mainly zinc alloy handles, and the lower-end market is mainly aluminum alloy handles and stainless steel handles. Because zinc alloy can not only be made into many designs and surface finishes, but also has a stronger hardness than aluminum alloy, and its price is more competitive than brass, so the door handle material currently used by door handle brands on the market is zinc alloy.
When choosing a handle, you need to focus on the electroplating process on the door handle surface. Because the electroplating process can ensure that the door handle is not oxidized, extending the service life of the door handle. What does the electroplating process of the door handle have to do with it? At this time, you need to pay attention to the thickness of the plating layer, the number of electroplating layer and the electroplating temperature.

 

Rosette & Escutcheon:
The rosette and escutcheon is mainly used to cover the spring mechanism of the door handle, and the shape is usually divided into a round and a square. Some special handle designs directly integrate the rosette and the handle. The common size on the market is probably between 53mm -55mm, but some countries and regions will be more special, the size will exceed 60mm or less than 30mm. In terms of thickness, the thickness of the traditional rosette and escutcheon is about 9mm, but due to the prevailing minimalist style, ultra-thin rosette have also begun to be popular, and the thickness is about half of the the thickness of the traditional rosette.

Mortise Lock Body:
The mortise lock body is an important part of a door handle lock. The most common ones on the market are single-latch lock bodies and double-latch lock bodies.Of course, there are other lock bodies like three-latch lock bodies. The basic components of the mortise lock body are: case, latch, bolt, forend, strike plate and strike case.
The opening hole distance of the door is related to the center distance and backset of the lock body. So if you replace the door handle lock, you need to measure the center distance and backset of the door hole before purchasing a new door handle lock.

Cylinder:
At present, the thickness of the door on the market is about 38mm-55mm, and the length of the cylinder is related to the thickness of the door. The cylinder is generally divided into 50mm, 70mm and 75mm, which needs to be choosed according to the thickness of the door.
Spring Mechanism & Mounting Kit:
The spring mechanism is a structure that connects the door handle and lock body, and the mounting kit is a structure that connects the cylinder and lock body. Whether the door handle lock runs smoothly and whether the door handle lock will drop down or not, that all depends on the spring mechanism and mounting kit.
