Abstract

A single-detent binder for a file folder has a housing, one pair of baseplates, ring shaped components, a control component, a pull rod, rotary locking pieces and an intermediate junction component. The control component, intermediate junction component, pull rod and rotary locking pieces are connected in series. When the control component rotates, the rotary locking pieces are triggered to rotate in the trough of the first baseplate based on the mechanical principle of connecting rod, thus performing the locking / unlocking function. When the binder is closed, the baffle plates on the second baseplate hinder the rotary locking pieces from rotation, thus generating a clamping force. After the baffle plates and rotary locking pieces work jointly to close the binder, the ring shaped components generate a scrambling force, thus enhancing the locking effect and preventing the single-detent binder from opening unexpectedly.

Description

technical field

[0001] The invention relates to a one-handed locking clip for holding loose-leaf papers, in particular to a one-handed locking clip with a pull bar and a locking block to enhance the locking function. Background technique

[0002] In order to facilitate the insertion or extraction of loose-leaf papers, one-hand lock clips (or ring binders) are often widely used in file folders or notepads. As is known in the prior art, a typical single-handed lock clamp mainly includes a long curved face shell, a pair of long bottom plates, multiple ring components and one or more control handles. The two longitudinal sides of the shell are bent inwardly to form two inner sides. The pair of base plates are disposed in the cavity formed by the curved face shell such that one of the two longitudinal sides of the base plates abuts against the inner side edge of the face shell, while the other longitudinal edge of each base plate is in parallel are connected to each other in a ...

Embodiment Construction

[0037] refer to figure 1 , The binder of the present invention mainly includes a face shell 01, a pair of bottom plates 02, a ring assembly 03, a control assembly 04, a pull rod 05, a rotating lock block 06 and an intermediate connection assembly 07.

[0038] Such as figure 1 , 9 As shown in 12, the face shell 01 is a longitudinally elongated structure made of metal or other suitable materials with sufficient rigidity to provide stability and light weight. There is a strip-shaped recessed space 011 on the top of the face shell 01 . The face shell 01 is bent downward along the two longitudinal sides of the top to form two longitudinal sides 012 . The longitudinal sides of the two longitudinal sides 012 are extended and bent inwardly to form two inner sides 013 against which the outer longitudinal edges of the pair of base plates 02 abut, thereby supporting the pair of base plates 02 to pivot in the face shell 01. The closed edge of the face shell 01 narrows the inner edge ...
