Description

Technical Field

[0001] The utility model relates to the technical field of leveling mechanisms, in particular to a leveling mechanism for keyboard bottom plate production. Background Art

[0002] The bottom plate is one of the components of the keyboard, usually refers to the main part of the keyboard, which is used to support and fix the various keys and circuit boards and other components of the keyboard. The material and production process of the keyboard bottom plate have a great influence on the texture and service life of the keyboard. The metal bottom plate is usually more sturdy and durable, and can provide better support and stability, but the cost is also relatively high. The plastic bottom plate is lower in cost, but may not be as durable as the metal bottom plate.

[0003] The leveling mechanism of the keyboard base is a device used to produce the keyboard base. Its main function is to level the keyboard base to improve the flatness and stability of the base.

Once the pressure is too large, it may cause damage to the keyboard bottom plate. The keyboard bottom plate made of metal has strong bearing capacity, but it will break randomly when encountering plastic material. Therefore, we need a leveling mechanism for keyboard bottom plate production. Utility Model Content
