office environment, filing cabinet is one of the indispensable storage tools. It is not only used to store all kinds of documents and materials, but also can effectively manage space and improve work efficiency. The handle, an important part of filing cabinet, is directly related to the convenience and safety of use. This paper will discuss the design concept and working principle of mechanical filing cabinet handle.

Design concept

1. Ergonomics: A good filing cabinet handle should conform to the principles of ergonomics, that is, its shape and size should be convenient for hands to grasp naturally and reduce hand fatigue during use.

2. Durability: Considering that the filing cabinet may be opened and closed frequently, the handle should be made of wear-resistant materials, and the structure should be stable to prolong the service life.

3. Aesthetics: With the change of office decoration style, the color and material of the handle should also be coordinated with the overall environment to enhance the visual effect.

principle of operation

Basic structure: Most mechanical filing cabinet handles are mainly composed of two parts-exposed operating parts (such as pull rings or knobs) and internal connectors. The operation part is responsible for receiving the power input by the user; The internal connector transmits the force to the cabinet door lock mechanism through mechanical transmission.

Opening and closing mechanism:

-For push-pull filing cabinets, when the user holds the handle and pulls it in his own direction, the inner link will drive the locking device to unlock, thus allowing the cabinet door to open. On the contrary, when the door is closed, after the handle is released, the spring return mechanism will automatically reset the lock catch and re-lock the door.

-And the rotary handle is usually used in the side door type filing cabinet. Turning the handle can trigger a gear system, which controls a series of pulleys or connecting rods connected with it, thus realizing the opening and closing of the cabinet door.

Security features:

-Some high-end products will also be equipped with anti-pick function, so even if someone tries to forcibly destroy the handle, it will not be easy to open the cabinet.

-Other designs may include child-resistant locks to prevent children from inadvertently opening drawers where dangerous goods are located.

In a word, although seemingly simple, there are complex and exquisite technical details behind the handle of mechanical filing cabinet. Reasonable handle design can not only greatly facilitate daily use, but also enhance the safety performance of the whole filing cabinet. future, with the support of new materials and technologies, we have reason to believe that filing cabinet handles will become more intelligent and humanized.
