Embodiment
Embodiments of the invention are described further referring to figs. 1 to Fig. 4.
It is a kind of to prevent that engaged transmission has character wheel successively in the mechanical counter of backwards rotation, including counter housing 1, housing
2, wherein the first character wheel is connected with the first character wheel 4 of first rotating shaft 3, the first driving is connected with the first character wheel 4 of first rotating shaft 3
The second actuator 7 engaged with the first actuator 5 is connected with part 5, counter housing 1, the second actuator 7 passes through the second rotating shaft
6, in the engagement of the first character wheel, wherein being all provided with retaining structure on the first actuator 5 and the second actuator 7, stir first clockwise
Actuator 5, the first actuator 5 drives the first character wheel up time to rotate, and the second actuator 7 does not play gearing, and the is stirred counterclockwise
One actuator 5, the second actuator 7 drives the first character wheel up time to rotate, and the first actuator 5 does not play gearing.
Pass through above-mentioned technical scheme：Character wheel 2 in the technical program Counter housing 1 is intermeshing in certain
System transmission, and the first character wheel plays first biography effect, and lead-in character wheel 2 is respectively by the first character wheel 4 of first rotating shaft 3 and the
Two rotating shafts 6 are connected with the first actuator 5 and the second actuator 7, therefore two actuators can all drive the first character wheel
Rotate, and two of which actuator is in intermeshing state, this also just says that it is clockwise turn to work as the first actuator 5
When dynamic, the rotation direction of the second actuator 7 is that rotating counterclockwise in contrast is presented certainly, and vice versa.If therefore one
Straight ensure that can borrow corresponding rotating shaft to drive the first character wheel to rotate in actuator rotationally clockwise, it is ensured that whole
Individual counter is always maintained at a rotation direction, even stirring the first actuator 5 counterclockwise.And be to realize that this effect spy exists
Retaining structure is all provided with first actuator 5 and the second actuator 7, the first actuator 5, the first actuator 5 are stirred clockwise
The first character wheel up time is driven to rotate, the second actuator 7 does not play gearing, the first actuator 5, the second actuator are stirred counterclockwise
7 drive the first character wheel up time to rotate, and the first actuator 5 does not play gearing.
The specific set-up mode of wherein described retaining structure is：All axle on the actuator 7 of first actuator 5 and second
There is neck to fluting, wherein retaining structure includes the gear 8 being sheathed on the first actuator 5 or the second actuator 7 and activity even
The card article 9 on gear 8 is connected to, the first actuator 5 and the second actuator 7 are realized by gear 8 to be engaged, and is caught on by card article 9
Neck on respective drive part, drives respective drive part to rotate.
When specific implementation, when rotating clockwise gear 8, the first drive is caught on by the card article 9 in respective gears 8
Neck on moving part 5 drives it to rotate, although the gear 8 being set on the second actuator 7 can also be produced in the presence of engagement
Rotate, but because gear 8 its rotation direction being arranged on the second actuator 7 is opposite, and the card being connected on two gears 8
Bar 9 is set in mutually opposing, therefore rotates it when the card article 9 on the first actuator 5 is seized actuator, the card article of opposite side
9 can not just catch on the neck on the second actuator 7, when backwards rotation on the contrary is set in the gear 8 on the first actuator 5, due to
Reverse card article 9 can unclamp from neck, and gear 8 can not catch on neck by means of card article 9 and drive it to rotate, and be set in the second actuator
Gear 8 on 7 is that the card article 9 being now set on the gear 8 of the second actuator 7 will in rotationally clockwise certainly
Take advantage of a situation and catch on neck, drive the second actuator 7 to rotate, ensureing anyway to stir whereby can ensure that counter is not in inverse
To the situation of rotation.
And in order to ensure that the rotation of itself of gear 8 will not directly drive actuator to rotate it is necessary to ensureing the gear 8
Coordinate in the first actuator 5 and the second actuator 7 for gap.
Card article 9 plays critically important effect wherein in the technical program, is the more preferable specific effect for ensureing card article 9,
The card article 9 is set in arcuate structure corresponding with actuator, in order to more preferably be adapted to, and the wherein volume its one end activity of card article 9 is consolidated
It is scheduled on gear 8, the other end offers snap fit 11, snap fit 11 realizes the concrete function for catching on neck.
In specific installation process, because the gear 8 at the position of fixing strip 9 to be provided with fixed projection
12, the fixture being detachably connected on projection 12 is fixed, card article 9 offers fixed via 10 in its relative one end, wherein solid
The diameter for determining through hole 10 is more than diameter of the diameter less than fixed block 13 of fixed projection 12, therefore card article 9 is enclosed on into fixed projection
After on 12 with fixture realize it is specific fixed just can be with.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
