Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

Embodiment 1

Please refer to Fig.1 shown in -4, a kind of ratchet device, including bottom plate 1, ratchet 2, dead axle 3, card slot 4, pawl 5, moving axis 6, Bull stick 7 fixes disk 8, conveyor chain 9, outer rotation axis 10, interior rotation axis 11 and adapting rod 12, and center is provided with ratchet on bottom plate 1 2, and several card slots 4 are provided at the neighboring of ratchet 2, by the way that card slot 4, and the bathtub construction of card slot 4 and spine is arranged The structure on 5 top of pawl matches, in this case, when ensureing to reset, it is ensured that the top of pawl 5 is just stuck on ratchet 2 Card slot 4 in, on the one hand ensure that precisely realizes 90 degree of stations in this way, is on the other hand required to return to original in driving shaft Position, acts in driven shaft movement in one direction structure huge, and the side of ratchet 2 is connected with pawl 5 by card slot 4, passes through and spine is arranged Pawl 5 and ratchet 2 etc. solve unilateral bearing and single direction rotation may be implemented, but can not precisely realize 90 degree of stations Problem, which can ensure 90 degree of stations, and continuous rotation is error free, and the top of pawl 5 is provided with moving axis 6, And the bottom end of ratchet 2 and the junction of bottom plate 1 are provided with conveyor chain 9, thus in the rotation by conveyor chain 9, together When drive ratchet 2 to be rotated together by adapting rod 12, the rotation that can give ratchet 2 in this way provides power resources, because And may be implemented to return to original position after moving axis 6 acts, ratchet 2 rotates 90 degree of purpose.

Embodiment 2

Please continue to refer to shown in Fig. 1-4, compared with above-described embodiment, the center of ratchet 2 is embedded with dead axle 3, and ratchet 2 with It is movably connected between pawl 5, by being mutually movably connected between ratchet 2 and pawl 5, thus ratchet 2 and spine may be implemented Pawl 5 is mutually rotated, and finally the case where resetting, and personnel easy to operation mount and dismount it, is carried out regular Cleaning and repair etc..It is provided with bull stick 7 on one side side wall of moving axis 6, and is provided with fixed disk 8 on the outer wall of moving axis 6, and turns Bar 7 is respectively between pawl 5 and moving axis 6 in rotation connection, and by the way that bull stick 7 is arranged, thus bull stick 7 is acted in switching, is driven Pawl 5 is rotated, thus moving axis 6 will not due to pawl 5 deviation post and therewith together into line displacement.Conveyor chain 9 wraps Outer rotation axis 10 and interior rotation axis 11 are included, and the diameter of outer rotation axis 10 is more than the diameter of interior rotation axis 11, and outer rotation axis It is symmetrical set between 10 and interior rotation axis 11, by the way that outer rotation axis 10 and interior rotation axis 11 is arranged, thus conveyor chain 9 can be given The rotation for giving ratchet 2 provides power resources.Adapting rod 12 is provided in outer rotation axis 10, and the top of adapting rod 12 is connected to spine The bottom end of wheel 2, and the rotation direction of adapting rod 12 and the rotation direction of ratchet 2 match, by the way that adapting rod 12, thus meeting is arranged So that ratchet 2 achievees the purpose that 90 degree of rotation.The bathtub construction of card slot 4 and the apex structure of pawl 5 match, and pass through setting Card slot 4, thus can ensure 90 degree of stations, and continuous rotation is error free.

When the utility model is used, first, which is mainly used in 53 ruler superelevation framves, moving axis 6 first by into Row rotates clockwise 90 degree, then in the rotation, this when ratchet 2 be it is motionless, and the rotation of moving axis 6 be with 2 axis of ratchet rotates, and is then followed by moving axis 6 and is carried out 90 degree of rotation counterclockwise again, then carries out rotation 90 in moving axis 6 When spending, at this time pawl 5 can be driven and be rotated by bull stick 7, and fixed disk 8 ensure that moving axis 6 will not deviate original Position, only rotated, then ratchet 2 rotates counterclockwise 90 degree under the drive of pawl 5, in this case, to real 2 actions back and forth of existing moving axis 6, homing, ratchet 2 rotate 90 degree of purpose, and the then rotation of ratchet 2 mainly passes through, Conveyor chain 9 is rotated, and then outer rotation axis 10 drives interior rotation axis 11 to be rotated, and in the rotation, can pass through Ratchet 2 is driven and is rotated by adapting rod 12.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation Involved claim.
