a folder

Abstract

The invention relates to a folder, which comprises a clamping seat, a plurality of fixed hooks, a plurality of movable hooks and operating handles, wherein the fixed hooks are fixedly arranged on one side of the clamping seat; the movable hooks are positioned on the other side of the clamping seat; the movable hooks are in one-to-one correspondence with the fixed hooks; the clamping seat is an extruded section; a fixing groove is formed on one side of the clamping seat, a shaft groove is formed on the other side of the clamping seat, and a cavity is formed in the middle part; the movable hooks are welded to a guide shaft in parallel; the two ends of the guide shaft are bent to form driving rods; the guide shaft is placed in the shaft groove of the clamping seat; the driving rods are transversely placed on the two end parts of the clamping seat; a support is fixedly arranged at the two ends of the cavity respectively; a reed is fixedly arranged at the vertex angle of a triangular port of the support; a suspending end of the reed is supported against the lower side of the driving rods; a linkage rod is arranged in the cavity in a penetrating way; an operating handle is fixedly arranged at the two ends of the linkage rod respectively; and cam faces of the operating handles are abutted against the surfaces of the driving rods. According to the folder, the section is used as a material of the clamping seat; and when folders of different length specifications are manufactured, only equal-length cutting is required to machine a notch.

Description

Technical field: [0001] The invention belongs to the field of stationery, and in particular relates to a folder whose main body is processed from profiled materials. Background technique: [0002] The existing paper perforated file folder is widely used and is very suitable for displaying and archiving paper materials. CN101687429A discloses a device named for keeping a stack of files in a file folder, including a base, a cylindrical part fixed on the base, an arched part matched with the cylindrical part, and an arched part that controls the opening and closing of the arched part. There is a platform in the center of the base, on which the switch is movably pivoted; there is a typical connecting rod at the bottom of the two arched parts, which passes through the platform and can When the switch part interferes, the left and right sliding of the switch part controls the opening and closing action of the arched part, and this structure has relatively large resistance during ...

CN101687429A discloses a device named for keeping a stack of files in a file folder, including a base, a cylindrical part fixed on the base, an arched part matched with the cylindrical part, and an arched part that controls the opening and closing of the arched part. There is a platform in the center of the base, on which the switch is movably pivoted; there is a typical connecting rod at the bottom of the two arched parts, which passes through the platform and can When the switch part interferes, the left and right sliding of the switch part controls the opening and closing action of the arched part, and the resistance of this structure is relatively large during operation.

The structure of the above two file folders is roughly the same. The holders used are all stamped and formed by iron sheets. Generally, only two pairs of file hooks can be processed. If four pairs of file hooks are processed, the holders need to be thickened, otherwise the iron sheet stamped The clamp seat is very easy to produce tile changes, which will affect the use effect
