Abstract

The invention discloses a convenience paper extractor. Support posts are symmetrically arranged on four corners of the outer bottom of a U-shaped paper box and mounted in respective post holder holes through pressure springs. Four post holders are fixed on a lower cover. One end of a sector gear and a torsion spring are hinged to the inner side of a long edge of an upper cover. The torsion spring is pressed to the inner side of one end of the sector gear. The other end of the sector gear meshes with a gear. The top of the other end of the sector gear contacts with the inner side of an extract button which is mounted on the upper cover. One end of a first rotating shaft is fixedly connected with the gear; the other end of the first rotating shaft is fixedly connected with a flywheel of an inner ratchet wheel. One end of a second rotating shaft is fixedly connected to a housing of the inner ratchet wheel, and the other end of the second rotating shaft is fixedly connected with a friction roller. Each rotating shaft and a support on the inner top of the upper cover form a rotating pair. The convenience paper extractor having the inner ratchet wheel, the friction roller and the pair of meshing gears only is simple in structure; paper can be extracted just by pressing the extract button, so that the convenience paper extractor is convenient to operate; the convenience paper extractor adaptable to paper different in size and type is widely applicable accordingly.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

As shown in Fig. 1-Fig. 7, the present invention includes the housing being formed by upper cover 1 and lower cover 2, paper delivery button 3, sector gear 4, gear 5, the first rotating shafts 6, friction roller 7, the second rotating shafts 8, the shell 9 of handle ratchet wheel,

torsion spring

10,11, four stage clips 12 of U-shaped paper holding frame, paper out opening 13, four bloom-

bases

14,15, four pillars 16 of flywheel body of handle ratchet wheel.On four jiaos of paper holding frame 11 outer bottoms, be arranged with respectively pillar 16, U-shaped paper holding frame 11 is arranged in lower cover, and four pillars 16 are arranged in bloom-base 14 holes separately by stage clip 12 respectively, and four bloom-bases 14 are fixed on down and cover, one end of sector gear 4 and torsion spring 10 are hinged on the inner side on upper cover one long limit, one end of torsion spring 10 is pressed on one end medial surface of sector gear 4, the other end of torsion spring is pressed on the upper rectangular column on upper cover 1 one long limits, the other end of sector gear 4 and gear 5 engagements, the interior side contacts of the top of the other end of sector gear 4 and paper delivery button 3, paper delivery button 3 is arranged on and covers, one end of the first rotating shaft 6 and gear 5 are affixed, the flywheel body 15 of the other end of the first rotating shaft 6 and handle ratchet wheel is affixed, second one end of rotating shaft 8 and the shell of handle ratchet wheel 9 are affixed, the other end of the second rotating shaft 8 and friction roller 7 are affixed, the first rotating shaft 6 and the second rotating shaft 8 form revolute pair with the supporting of upper cover inner top surface respectively.

As shown in Figure 1, Figure 2, shown in Fig. 5, Fig. 6, described upper cover 1 below surrounding is equipped with baffle plate, the plate washer width on wherein said upper cover one long limit will be wider than the baffle plate on other three limits, the upper cover 1 below baffle plate of surrounding matches with lower cover 2 inside casings.

As Fig. 1, Fig. 4, as shown in, described lower cover 2 has paper out opening 13 towards a side of U-shaped paper holding frame 11 opening directions.

As shown in Fig. 3, Fig. 7, the outer width of frame of described U-shaped paper holding frame 11 and length are less than respectively width and the length of lower cover inside casing.

As shown in Figure 1, described friction roller 7 is positioned at the middle part of U-shaped paper holding frame 11, and parallel with U-shaped paper holding frame 11 minor faces.

Operation principle of the present invention is as follows:

As shown in Fig. 1～Fig. 7, a stacker is placed in U-shaped paper holding frame 11, the gravity of paper can be pressed on stage clip 12 by U-shaped paper holding frame 11, by uppermost a piece of paper in flexible assurance one stacker of stage clip 12, contacts all the time with friction roller 7.While pressing paper delivery button 3, sector gear 4 is subject to a downward power, and sector gear 4 is rotated around the axis of oneself, and torsion spring 10 is squeezed simultaneously, and torsion spring 10 is given 4 one reaction forces that make progress of sector gear, also rotates with sector gear 4 meshed gears 5.Gear 5 drives the first rotating shaft 6 to rotate, the first rotating shaft 6 drives the flywheel body 15 of handle ratchet wheel to rotate, the flywheel body 15 of handle ratchet wheel drives the shell 9 of handle ratchet wheel to rotate, the shell 9 of handle ratchet wheel drives rotating shaft 8 to rotate, the second rotating shaft 8 drives friction roller 7 to rotate, thereby make between uppermost a piece of paper, to produce frictional force in friction roller 7 and a stacker, due to the effect of frictional force topmost a piece of paper be pushed, and be exported housing from paper out opening 13.When Panasonic's paper delivery button 3, because the reaction force of torsion spring 10 makes sector gear 4 rotate backward round the rotating shaft of oneself, also rotate backward with sector gear 4 meshed gears 5, gear 5 drives the first rotating shaft 6 to rotate backward, the first rotating shaft 6 drives the flywheel body 15 of handle ratchet wheel to rotate backward, but because handle ratchet wheel has one-directional rotation, the shell 9 of handle ratchet wheel is static, thereby friction roller 7 is static.This has just completed a complete paper process of getting.
