Abstract

The utility model provides a folder, which includes foldable pages with a back cover, a front cover and a side bar. A clamping device is arranged at the back cover close the middle of the side bar. The clamping device includes a bottom plate fixed on the back cover and a side plate integrated with and perpendicular to the bottom cover, and a press rod is hinged on one end of the side plate. A torque spring is arranged on the bottom plate, one end of the torque spring is connected with the press rod, and the other end is connected with the press plate. The press plate is at the side of the side plate opposite to the press rod above the bottom plate. A downward barb is arranged at the end of the side plate facing the press rod, a long via slot fitting the barb is arranged at the corresponding end of the press rod, and one end of the torque spring is bent and plugged into the long via slot. The long via slot has a bending part in the middle. A user can press the papers through pressing the press rod and thus making the long via slot fitted with the barb on the side plate.

Description

A kind of folder structure

Technical field:

The utility model relates to a kind of folder structure, particularly relates to the file clamping structure that can conveniently open and close.

Background technology:

Existing file, comprise the page or leaf of amounting to that to amount to, amounting to page or leaf is made of front cover, back cover and edge strip, back cover is provided with the clamping structure near the edge strip centre position, the clamping structure comprise the base plate that is installed on the back cover and with the side plate of base plate one perpendicular to base plate, side plate one end is hinged with depression bar, the depression bar end is provided with the grab that stretches out to the side plate direction, just can cooperate with the draw-in groove that the edge strip opposite side is provided with, base plate is provided with torsion spring, torsion spring one end connects depression bar, and the other end connects pressing plate, and pressing plate is positioned at base plate top, the depression bar opposite side with respect to side plate.When this kind file used, the user was engaged in the draw-in groove grab by down-pressed pole, and paper spare will be compressed between pressing plate and the base plate, press down-pressed pole, outwards stir, can make grab break away from draw-in groove, pressing plate lifts, and paper spare can be taken out, and stage clip plays the effect that increases pressure and reset.

Summary of the invention:

The utility model provides a kind of folder structure, and its purpose is to provide a kind of file that is different from existing structure, can more conveniently use effectively.

For reaching above-mentioned purpose, the utility model adopts following technical scheme:

A kind of folder structure, comprise and have back cover, front cover and edge strip amount to page or leaf, back cover is provided with the clamping structure near the edge strip centre position, the clamping structure comprise the base plate that is installed on the back cover and with the side plate of base plate one perpendicular to base plate, side plate one end is hinged with depression bar, base plate is provided with torsion spring, torsion spring one end connects depression bar, the other end connects pressing plate, pressing plate is positioned at the base plate top, depression bar is with respect to the opposite side of side plate, it is characterized in that: side plate has downward barb towards an end of depression bar one side, the corresponding end of depression bar is provided with the long strip type groove, one end of the terminal extension rod of torsion spring is crooked and stretch into the long strip type groove, and the terminal extension rod of torsion spring embeds barb during the clamping state.

Long groove middle part has bending.

The usefulness of technique scheme is: the user only need be by down-pressed pole, and the terminal extension rod of torsion spring is cooperated with barb on the side plate, just can push down paper spare.

Description of drawings:

Below with accompanying drawing the utility model is described in detail:

Fig. 1 is the utility model schematic perspective view

Fig. 2 is the schematic perspective view of another direction of the utility model

Fig. 3 is the utility model clamping state schematic perspective view

The specific embodiment

As Fig. 1, Fig. 2, the utility model embodiment shown in Figure 3, has back cover 11, front cover 12 and edge strip 13 amount to page or leaf, back cover 11 is provided with the clamping structure near edge strip 13 centre positions, the clamping structure comprise be installed on the back cover 11 base plate 21 and with the side plate 22 of base plate 21 one perpendicular to base plate 21, side plate one end is hinged with depression bar 3, be installed with torsion spring 4 on the base plate 21, torsion spring 4 ends have extension rod 42, extension rod 42 1 ends have bending 41 and stretch into the long strip type groove 31 that is provided with on the depression bar 3, torsion spring 4 other ends connect pressing plate 5, pressing plate 5 is positioned at base plate 21 tops, depression bar 3 is with respect to the opposite side of side plate 22, side plate 22 has downward barb 221 towards an end of depression bar 3 one sides, and above-mentioned long groove 31 middle parts have crooked 311.It is more stable with crush board 5 also to be hinged with crank 111 between base plate 21 and the pressing plate 5.

During the clamping state, barb 221 cooperates and blocking depression bar 3 with extension rod 42, and paper spare can be pushed down by pressing plate 5 under torsion spring 4 effects.

Only need to press down-pressed pole 3, just can make barb 221 and extension rod 42 break away from blocking.

When depression bar 3 lifted, because crooked 311 existence, bending 41 that can contact torsion spring 4 can oneself not fall depression bar 3.

Claims
