Description

A folder for secondary closing

technical field

The invention relates to the technical field of office supplies, in particular to a folder for secondary closing.

Background technique

There are various file folders for home and office use. Most file folders can only be opened after pressing the clamping device of the folder with external force. When the external force disappears, the folder is in a clamped state. When the clamping action is frequent, the clamping device needs to be pressed frequently, which causes more physical exertion for the user and affects work efficiency.

And the reference document 201210190358.6 discloses a new type of folder, which makes the handle press the push block to keep the open state by moving the hook frame; the user only needs to press the handle so that the part of the handle pressing the push block leaves the push block. block, so that the pressing force on the push block disappears, and the folder can be clamped. The operation is simple and fast, but the closing speed of the folder is fast, and the noise generated is very large, which is not convenient for daily use. Fast, so the impact force is very strong, which is easy to cause damage to the folder, which is not conducive to the service life of the folder, and even causes injury to the human body.

During the closing process of the clamping assembly 2, The control rod 311 rotates and abuts against the operating member 32, so that the rotating member 31 stops rotating due to resistance, so that the clamping assembly 2 stops closing the clamp. At this time, the clamping assembly 2 is in a half-closed clamping state, and then the pressing operating member is released 32. The operating part 32 resets under the action of the elastic element 33, and at the same time the control rod 311 pushes against the operating part 32 and rotates slowly until the clamping assembly 2 is completely closed. The structure design of the present invention is ingenious and reasonable in use. Reduce the closing speed of the clamping assembly 2, realize the secondary closing of the folder, reduce the noise of closing the folder, or even have no closing noise, and reduce the impact of the clamping assembly 2 on the folder at the same time, prolong the folder's life. Long service life, to avoid human injury caused by misuse.

In this embodiment, control rods 311 are arranged on both sides of the rotating member 31 , and the control rods 311 are arranged symmetrically, so that the force on the control rods 311 is more uniform and stable, and at the same time, the service life of the control rods 311 is prolonged.

In this embodiment, the clamping assembly 2 includes a clamping member 21 and a torsion spring 22 provided on the clamping member 21, and the clamping member 21 is pivotally connected to the base 1 through the torsion spring 22; specifically, the torsion The spring 22 is embedded in the inside of the base 1 to prevent mutual destruction between the torsion spring 22 and the outside during operation, and protect the torsion spring 22.
