The specific embodiment
As depicted in figs. 1 and 2, a kind of predetermincd tension mechanism of ratchet wheel type binder, ratchet wheel type binder comprises support 1, bundling belt, rotating shaft 3 and tape spool 4, rotating shaft 3 is connected to has the take-up assembly that can drive rotating shaft 3 to rotate on support 1 and on support 1, tape spool 4 is connected on support 1, and the quantity of bundling belt is two: front bundling belt 2a and rear bundling belt 2b.Rotating shaft 3 middle parts offer rectangular through hole along its axle, and front bundling belt 2a passes this rectangular through hole and is fixed in rotating shaft 3.Rear bundling belt 2b is enclosed within on tape spool 4, and this mechanism comprises the elastic component 5 that is positioned at support 1, and elastic component 5 is rubber block.Select rubber block as elastic component 5, make the elasticity of elastic component 5 better, thereby make the pretension better effects if of bundled device.The end of rear bundling belt 2b is enclosed within on elastic component 5 and tape spool 4 simultaneously, under the seizing force effect of bundled device elastic component 5 be pressed on after between bundling belt 2b and tape spool 4.
Take-up assembly comprises handle 7, ratchet 8, tooth pushing plate 9 and gear tooth plate 10, handle 7 is hinged on support 1 by rotating shaft 3, ratchet 8 is connected in rotating shaft 3 ends, tooth pushing plate 9 is movably connected on handle 7 and between is provided with spring 1, under the elastic force effect of spring 1, tooth pushing plate 9 is resisted against between the ratchet of ratchet 8, gear tooth plate 10 is movably connected on support 1 and between has spring 2 12, is resisted against between the ratchet of ratchet 8 at the elastic force effect lower block tooth plate 10 of spring 2 12.Hinged place on handle 7 is set in rotating shaft 3, and handle 7 is axially connected with rotating shaft 3, circumferentially free to rotate.When take-up, turning handle 7, handle 7 drives tooth pushing plate 9 to move, and on ratchet, a comparatively level and smooth side direction tooth pushing plate 9 ends and is moved.Ratchet promotes tooth pushing plate 9 away from ratchet 8, crosses after tooth pushing plate 9 when a ratchet, and due to the setting of tooth pushing plate 9 upper springs 1, tooth pushing plate 9 is reset between ratchet.Handle 7 drives tooth pushing plate 9 to cross after some and ratchet, and handle 7 rotates backward, and now, tooth pushing plate 9 is resisted against a side steeper on ratchet, and tooth pushing plate 9 cannot be crossed from ratchet, and therefore, tooth pushing plate 9 drives ratchet 8 to rotate, and carries out take-up action.After take-up, bundling belt has certain tightening force, but under the effect of gear tooth plate 10, ratchet 8 cannot turn round.Bundling belt is tightened up location.
In support 1, also have the tressel 6 that a cross section is Contraband font, as shown in Figure 4, have recessed installation cavity 6b on tressel 6, elastic component 5 is positioned at installation cavity 6b place and its part is stretched out installation cavity 6b.Elastic component 5 is connected in installation cavity 6b.The part that elastic component 5 stretches out installation cavity 6b is resisted against on tape spool 4.Between tressel 6 and support 1, have and can make the guide frame of tressel 6 along support 1 translation, under the seizing force effect of bundled device, bundling belt is pressed on tressel 6.Elastic component 5 is arranged in tressel 6, the setting of guide frame, and the direction action that tressel 6 can only limit along guide frame, makes the structure of elastic component 5 comparatively stable.
Under the effect of take-up assembly, bundling belt is tightened up.When after bundled device take-up, front bundling belt 2a and rear bundling belt 2b are all subject to the effect of seizing force, and rear bundling belt 2b is set on elastic component 5 and to elastic component 5 has squeese pressure, but due to the setting of tape spool 4, elastic component 5 is limited.Under the combined action of rear bundling belt 2b and tape spool 4, elastic component 5 is extruded distortion.Now, elastic component 5 has the trend of the shape that resiles, and elastic component 5 also has squeese pressure to rear bundling belt 2b and tape spool 4 simultaneously.Therefore, front bundling belt 2a and rear bundling belt 2b all have predetermincd tension.Even if ratchet 8 produces a bit of reversing, under the effect of elastic component 5, bundling belt still has predetermincd tension.Due to the setting of the interior elastic component 5 of support 1, make the pretension effect of bundled device better.
As shown in Figure 4, have curved recessed contact part 5a on elastic component 5, and contact part 5a and tape spool 4 sidepieces match, the contact part 5a of elastic component 5 abuts in tape spool 4 sidepieces.Contact part 5a is set on elastic component 5, has increased the area of contact between elastic component 5 and tape spool 4, make the annexation between elastic component 5 and tape spool 4 more tight, in use, structure is also more stable.
As shown in Figure 3, guide frame is the guiding plush copper 6a that protrudes of tressel 6 both sides and is positioned at the bar hole 1a that support 1 both sides are bar shaped, and two guiding plush copper 6a lay respectively at corresponding bar hole 1a place.Under the restriction of bar hole 1a, tressel 6 moves along the direction of bar hole 1a.Such structure Shi Ben mechanism is comparatively stable.
As another kind of scheme, guide frame is that tressel both sides are the gib block of bar shaped protrusion and are positioned at the guide groove that support both sides are bar shaped, and two gib blocks lay respectively at corresponding guide groove place.Under the restriction of gib block and guide groove, tressel moves on support along the direction of guide groove, and its structure is comparatively stable.
As another kind of scheme, take-up assembly comprises crow bar, ratchet and gear tooth plate, rotating shaft is hinged on support and at rotating shaft sidepiece has the jack for crow bar insertion, ratchet is connected in roller end, gear tooth plate is movably connected on support and between has spring two, is resisted against between the ratchet of ratchet at the elastic force effect lower block tooth plate of spring two.When take-up, crow bar is inserted to the jack of rotating shaft sidepiece, pull crow bar, drive rotating shaft to rotate, thereby bundling belt is tightened up.After bundling belt is tightened up, have the rotating trend of the rotating shaft of drive, but under the effect of gear tooth plate, ratchet is positioned, therefore, rotating shaft is also positioned, no longer revolution.After this, bundling belt is tightened up location.
As another kind of scheme, elastic component is spring.The two ends of spring are resisted against respectively on tressel and tape spool.Select spring as elastic component, its elasticity is better.
