Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In description of the present utility model, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, it is only the utility model for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See figures.1.and.2 known, a kind of clockwise and anticlockwise ratchet mechanism, comprise outer ratchet 1, internal clickwork 4, external gear 2, internal gear 3, outer ratchet wheel seat 5, interior ratchet wheel seat 8, ratchet A6, ratchet B12, power input gear 11, plectrum structure 7, outer ratchet 1 is coaxially arranged with internal clickwork 4, external gear 2 and outer ratchet 1 are connected, internal gear 3 and internal clickwork 4 are connected, and power input gear 11 engages with external gear 2 and internal gear 3 respectively; Ratchet A6 one end is rotatably arranged on outer ratchet wheel seat 5, the other end contact is with outer ratchet 1 and its lower end is provided with elastomer C16, ratchet B12 one end is rotatably arranged on interior ratchet wheel seat 8, the other end contact is with internal clickwork 4 and its side is provided with elastomer B10, ratchet A6 and ratchet B12 is arranged in the same way: interior ratchet wheel seat 8 is provided with plectrum groove 15, plectrum structure 7 rotatably arranges on outer ratchet wheel seat 5, and its lower end is placed in plectrum groove 15, its upper end is placed in ratchet A6 top to drive ratchet A6 to press down or upper bullet; On outer ratchet wheel seat, 5 are provided with cavity volume 14, one-body moldedly on interior ratchet wheel seat 8 be provided with key body 13, key body 13 is placed in cavity volume 14, is also provided with elastomer A9 in cavity volume 14, elastomer A9 one end is connected to cavity volume 14 side inwall, and the other end is connected to key body 13.
When power input gear 11 rotates clockwise input, external gear 2 rotating in same direction engaged with it, drive the outer ratchet 1 also rotating in same direction be connected with external gear 2, ratchet A6 engages with outer ratchet 1, outer ratchet wheel seat 5 utilizes ratchet A6 to realize rotating clockwise with engaging of outer ratchet 1, and now outer ratchet wheel seat 5 rotating speed is lower.
When power input gear 11 rotates clockwise input, the internal gear 3 engaged with it oppositely rotates counterclockwise, drive the internal clickwork 4 be connected with internal gear 3 to rotate counterclockwise, cause the ratchet B12 touched with internal clickwork 4 to skid, ratchet wheel seat 8 and internal clickwork 4 relative sliding therefore.
