Abstract

A bidirectionally and automatically snapped hard surface clip comprises a front hard leaf and a rear hard leaf. The bidirectionally and automatically snapped hard surface clip is characterized in that a chuck with an inner groove formed by folding inwards an elastic piece is connected between the front hard leaf and the rear hard leaf, the front edge of the chuck with the inner groove is fixedly connected with the front hard leaf, the rear edge of the chuck with the inner groove is fixedly connected with the rear hard leaf, and corresponding surfaces of the front hard leaf and the rear hard leaf are automatically fastened. The elastic piece is folded inwards to form the inner groove, two mutually parallel sides of the inner groove are expanded into the front hard leaf and the rear hard leaf which can be horizontally unfolded, the front hard leaf and the rear hard leaf are bidirectionally and automatically snapped and closed to form a protection clip by the elastic restoring force of the inner groove, a crack is strongly unfolded when the front hard leaf and the rear hard leaf are horizontally unfolded, elastic resetting and clamping are rapidly realized, and the bidirectionally and automatically snapped hard surface clip is high in clamping force, flexible to operate, safe and reliable and cannot be affected by drop and collision.

Description

Two-way automatic snap-on stiff dough folder

Technical field

The utility model relates to a kind of file, and a kind of stiff dough folder that clamps loose-leaf comprises file, account folder or photograph album.

Background technology

Existing can clamping loose-leaf file chuck or clamped by spring, or by the clamping of band flexure strip, file by the collet clamping, big but the structure more complicated of clamping force, comprise helical spring, spring fixed seat, with the fixing lever of spring one end and with the fixing holding piece of the spring other end, spring fixed seat is fixed on top or the medial surface of file, shake clamping loose-leaf file by the lever drives holding piece, because spring and lever rotate flexibly, this file is easy to use, flexibly, only depend on the overhead kick of lever side but shortcoming is bite, contact-making surface is little, clamp not strongly solid, particularly being collided or touched easily when landing and flick, make the loose-leaf file disorderly completely, is the structure more complicated again, cost is higher.The chuck that the band flexure strip clamps is by shell fragment bending triangle, closed up by the triangle drift angle to clamp the loose-leaf file, opens folder mouthful by the lever that is located at both sides, and the strong chucking power of clamping force is big, operates dumbly, but cost simple in structure is low.CN2594016Y discloses a kind of file of being convenient to strut, and triangle clamp opening is made similar lip, and a folder mouthful edge forms wideer slit, to reduce the resistance that file enters.But it omits lever and the chucking power thereof of opening the slit, and the wide seam clamping loose-leaf that only depends on the triangle drift angle to close up reduces chucking power, and flexibility weakens.

Summary of the invention

The utility model is at the above-mentioned defective that is clamped or existed by the file that flexure strip clamps by spring, design a kind of stiff dough that is clamped by flexure strip originally, make stiff dough originally have the clamping force of collet, the two-way automatic spring snap type stiff dough that compresses of flexible and convenient operation originally.

Two-way automatic snap-on stiff dough folder, the hard page or leaf in hard page or leaf and back before comprising, it is characterized in that hard page or leaf is connected by the chuck that is converted into inner groovy in the flexure strip between the page or leaf firmly with the back before described, the front of described inner groovy chuck and described preceding hard page or leaf are connected and fixed, the back of described inner groovy chuck is connected with the hard page or leaf in described back and tightens up, described before the automatic fastening of corresponding surface of hard page of hard page or leaf and back.

Be converted into the isosceles triangle inner groovy in the described flexure strip.

Be converted into the inner groovy of band at the bottom of the rectangular channel in the described flexure strip.

Be converted into the annular inner groovy in the described flexure strip.

Described inner groovy chuck is inboard by the fixing corresponding forward and backward hard page or leaf of the alternate polyphone of inner groovy of some sections isosceles triangles.

Described inner groovy chuck is inboard by the fixing corresponding forward and backward hard page or leaf of the inner groovy alternate polyphone of some sections bands at the bottom of the rectangular channels.

Described inner groovy chuck is inboard by the fixing corresponding forward and backward hard page or leaf of the some sections alternate polyphones of annular inner groovy.

The beneficial effect of above-mentioned design is as follows; the inner groovy that is constituted by the flexure strip invagination; but the both sides that inner groovy is parallel to each other are extended to the forward and backward hard page or leaf of horizontal development; the inner groovy elastic restoring force is closed up the two-way automatic snap-on of forward and backward hard page or leaf and is formed the protection folder; when forward and backward hard page or leaf level was opened, brute force was opened crack, and the elastic reset clamping is quick; clamping force is not dropped by force to collide influences flexible operation, safe and reliable.
