One-handed lock clip

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 ...

AI Technical Summary

Problems solved by technology

[0004] Existing one-handed lock clips with locking systems are relatively complex in design, each locking component needs to have a specific shape to fit the opening in the base plate

Another disadvantage is that the pull rod is located between the face shell and the bottom plate, and the face shell needs to have a certain shape and thickness to accommodate the pull rod and the locking assembly protruding from its surface

A further disadvantage is that with typical one-handed latches, the initial force comes from the applied force on the control handle, which in some cases (such as when the face shell is slightly deformed) may not be evenly transmitted to the entire length. base plate, causing the base plate to fail to pivot
