Detailed description of the invention
Embodiment 1.Fig. 1,2,4 illustrates a kind of embodiment of the present invention.During the built-in closed filter gall 3 of grafting, by pentagon connected structure 7 grafting mutual to the pentagon connected structure 7 outside the non-circular connected structure 7 of built-in closed filter gall 3 arranged inside the lower bracket of handle mechanism 8 cover 8a, mutually rotate to prevent two parts, simultaneously, the gear-like lifting head 9a of the lifting head 9 of built-in filter gall 3 is lifted as handle mechanism 8, insert in the gear-like grafting breach of built-in filter gall 3 stretching structure, its three export-oriented double wedge 9b corresponding disengaged position in each interior three breach 7d between double wedge 7b.
Press the button 16 being positioned at handle mechanism 8 central authorities, position teeth change wheel case 15 moves down along the axial slide rail of the single direction ratchet overcoat 14 be fixed on support 8a, promote to be in it that single direction ratchet rotation set 13 of non-fully interlocking pattern e is also corresponding to be moved down, until its ratchet crown is engaged completely lower than being in during single direction ratchet overcoat 14 lower end: under the effect of spring 12 upwards screen resilience, the ratchet crown of single direction ratchet rotation set 13 breaks away from the restriction of the downward teeth of position teeth change wheel case 15 and the axial slide rail grooved rail of single direction ratchet overcoat 14, by extreme lower position upwards turn be transitioned into single direction ratchet overcoat 14 being downwards engaged of ratchet coordinate, and namely continuation rotation switches lower position b to the ratchet tooth root place that single direction ratchet overcoat 14 is downward.In the process, gear-like lifting head moves down with the propulsion arm 10a as yoke frame 10 and rotates by single direction ratchet rotation set 13 rotation direction, its export-oriented double wedge 9b moves down and to shift out in built-in filter gall 3 to the breach 7d between double wedge 7b, turns to below to double wedge 7b in next.Now, extract handle mechanism 8, the pentagon connected structure 7 of its underpart support casing 8a still with between the pentagon connected structure 7 outside the non-circular connected structure of built-in closed filter gall 37 keeps mutual grafting to coordinate, uniform each interior of built-in filter gall 3 stretching structure contacts up and down to the export-oriented double wedge 9b of double wedge 7b and gear-like lifting head, and by the weight of built-in filter gall 3, the propulsion arm 10a of gear-like lifting head together with load-bearing is left behind, until connect and compose reducing propulsion arm boss integrally with gear-like lifting head 9 to move down the spacing lower carriage 11a touched on support casing 8a, then the weight of built-in filter gall 3 is born by spacing lower carriage 11a.The grafting mutual to the pentagon connected structure 7 outside the non-circular connected structure 7 of built-in closed filter gall 3 of pentagon connected structure 7 due to handle mechanism 8 lower bracket cover 8a, avoid built-in closed filter gall 3 to occur relatively rotating, cause the interior phenomenon to double wedge 7b and export-oriented double wedge 9b slippage to occur.Handle mechanism 8 and built-in closed filter gall 3 connect and compose one.The axial pentagon connected structure 7 of existing corresponding matching between the two, to the annexation up and down between double wedge 7b and export-oriented double wedge 9b in also existing.Now, button 16 is positioned at the low level extracting handle mechanism 8.
Again press the button 16, position teeth change wheel case 15 is moved down along the guiding grooved rail of the single direction ratchet overcoat 14 be fixed on support 8a, promote to be in it that single direction ratchet rotation set 13 of non-fully interlocking pattern e is also corresponding to be moved down, until its ratchet crown be engaged completely with single direction ratchet overcoat 14 lower than rotating during single direction ratchet overcoat 14 lower end and to move along this occlusion mating surface: under the effect of screens spring 12 upwards screen resilience, enter the axial slide rail grooved rail of single direction ratchet overcoat 14 interior and move to a high position and namely arrive switching high position a.In the process, gear-like lifting head first moves down with reducing propulsion arm 10a, upwards turn under the effect of spring 12 screen resilience again, its export-oriented double wedge 9b is back in interior breach 7d position between double wedge 7b and disengaged position, throws off and interior continuous action relation up and down between double wedge 7b.Button 16 and position teeth change wheel case 15 are in a high position.Extract handle mechanism 8 disengagement to coordinate with the axial grafting of built-in closed filter gall 3 to be connected.
In embodiment 1, unsettled gear-like lifting head 9a is linked by propulsion arm 10a and single direction ratchet rotation set 13.Wherein, unsettled gear-like lifting head 9a and the propulsion arm 10a of load-bearing connects as one, its each export-oriented double wedge 9b and interior to double wedge 7b, and propulsion arm 10a, spacing lower carriage 11a bear built-in filter gall 3 weight.Between propulsion arm 10a and single direction ratchet rotation set 13, two component axials simultaneously with rotation and axial linkage structure both can have been adopted to overlap grafting pattern mutually, or employing is interconnected the tactic pattern be integrated, meets two component axials and move down and rotate interlock needs.In order to avoid affecting and improving its force-bearing situation, usually gear-like lifting head 9a will be set in propulsion arm 10a bottom; Non-circular shaft coordinates to plug to the axial grafting of the corresponding non-circular inner sleeve 13a of single direction ratchet rotation set 13 bottom at an upper portion thereof.When built-in filter gall 3 by interior to double wedge 7b, gear-like lifting head is left behind together with propulsion arm 10a time, the axial plug of propulsion arm 10a moves down along the inwall of the corresponding non-circular inner sleeve 13a of axis of single direction ratchet rotation set 13 bottom, but still keep coordinating with its grafting, then limit propulsion arm 10a by spacing lower carriage 11a and move down and bear the weight of built-in filter gall 3.When gear-like lifting head screws in disengaged position, propulsion arm 10a is under spring 12 acts on, and the non-circular inner sleeve 13a of axis along single direction ratchet rotation set 13 bottom moves up, and causes the grafting length of fit between two parts longer.
Position teeth change wheel case 15 and single direction ratchet rotation set 13 stagger a correspondence position, that non-fully interlocking pattern e is set in order to be engaged mating surface at both, be conducive to both in the disengagement of lowest part cooperation and the guiding to single direction ratchet rotation set 13, make it smoothly transit to downward being engaged of ratchet of single direction ratchet overcoat 14 and coordinate.
As the simplification structure of above-mentioned shift mechanism, also the correspondence position staggered can be cancelled by corresponding with the axial sliding-rail groove in single direction ratchet overcoat 14 for the position teeth change wheel case 15 boss d that circumferentially the corresponding crown in face is uniform, namely the teeth kept down and the single direction ratchet rotation set 13 being positioned at axial slide rail grooved rail being upwards engaged completely of ratchet, thus there is non-fully interlocking pattern e when being engaged both avoiding occurring.
