Structure of lever-type paper-bearing dish

Abstract

The invention discloses a structure of a lever-type paper-bearing dish, comprising a fixed block assembled at one end of the paper dish; the other end of the fixed block is rotatably matched with a first rotating shaft which is fixedly installed and sheathed with a handle which correspondingly rotates, the tail end of the handle is rotatably matched and connected with a limiting self-locking block, the middle position of the liming self-locking block is assembled with a second rotating shaft butted against the internal surface of the fixed block; the tail end of the limiting self-locking block is assembled with a buckling and pressing pulley which is buckled and pressed with the tail end of a circular structure of the fixed block and controls the downward movement of the tail end of the fixed block; the tail end of the fixed block is also assembled with a returning spring, and the other end of the returning spring is fixedly connected; the handle is mainly used for operating vertical control and enhances the convenient and fast property of the control; the arrangement of a driving pulley mainly strengthens the mating degree between the handle and the limiting self-locking block; the lever principle and the cantilever beam principle are utilized, paper operation is labor-saving, convenient and reliable; and an internal groove body is designed at the front end of the limiting self-locking block, thus improving the accuracy of the rotation of the limiting self-locking block.

Description

technical field [0001] The invention relates to the technical field of office paper trays, in particular to a lever type paper tray structure. Background technique [0002] Commonly used letters and stationery are stored and sequentially imported by the paper tray. The paper tray is widely used because it can store paper and can improve the operation efficiency of the supporting equipment; the control method of the general paper tray adopts automatic operation. Or manual operation; manual operation mostly adopts the operation mode of rotating the bracket, and one of these operation modes has no automatic reset mechanism, which cannot guarantee the self-rebound of the tray during operation, which is not conducive to the actual operation efficiency The improvement; the second is that the paper tray adopts the rotating operation mode, and its force is relatively large. If the lever principle is adopted, the actual operating force will be greatly reduced. Contents of the inven...
