Problems solved by technology

This kind of spring clip has been used for many years, but it has a problem, that is, when the clip is in the clamping state, because the handle drives the torsion spring to move downward, the pressure generated makes the two ends of the bottom plate diagonally stressed unevenly, causing the bottom plate There is warping
At present, there are two methods to reduce the warpage of the bottom plate: 1. Increase the thickness of the bottom plate to increase the rigidity of the bottom plate, thereby reducing the warpage, but this method will increase the material cost of the bottom plate; 2. Reduce the spring force, but This method will make it easier for the held document to fall out of the clip

Embodiment Construction

[0008] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] combine figure 1 , figure 2 It can be seen that the spring folder of the present invention includes a base plate 1 and a side plate 2, the base plate 1 is provided with a plurality of fixing ears 3, and the rivet supporting the torsion spring 4 is a U-shaped rivet 5, and one end of the U-shaped rivet 5 passes through the side plate 2 and the torsion spring 4 are installed on a fixed ear 3, and the other end also passes through the side plate 2 and is connected with the other fixed ear 3. One end of the torsion spring 4 is stuck in the lower part of the handle 6, and the other end is bent and flexibly connected with the bead 7. Two sides of the torsion spring 4 are respectively provided with a Z-shaped rotating arm 8 , one end of the two Z-shaped rotating arms 8 is movably connected with the fixed ear 3 , and the other end is movably ...

Abstract

A spring document binder is composed of side plate, bottom plate, multiple fixing lugs on bottom plate, torsion spring, handle, pressing bar, and two Z-shaped rotary arms. The U-shaped rivet for supporting the said torsion spring has one end passing through the torsion spring and is fixed between the side plate and one fixing lug. Its advantages are no buckle of bottom plate and saving raw material of bottom plate by 20% or more.

Description

(1) Technical field: [0001] The invention relates to a spring clip used on file folders. (two) background technology: [0002] The spring clip on the existing file folder includes a bottom plate, and the bottom plate is provided with a plurality of fixed ears, and the torsion spring is installed on the fixed ear through an I-shaped rivet. One end of the torsion spring is stuck in the lower part of the handle, and the other end is bent and flexibly connected with the bead; There is a Z-shaped rotating arm on both sides of the torsion spring. One end of the two Z-shaped rotating arms is movably connected to the fixed ear, and the other end is movably connected to the bead; A hole corresponding to the detent is provided. This kind of spring clip has been used for many years, but it has a problem, that is, when the clip is in the clamping state, because the handle drives the torsion spring to move downward, the pressure generated makes the two ends of the bottom plate diagonall...
