Abstract
The utility model relates to mechanical field, especially a kind of click driving mechanism, it comprises fork (9), ratchet connecting sleeve (4), transmission shaft (7), end cap (8), connecting base (3) and ratchet (5), spring (6) is provided with in described ratchet connecting sleeve (4), each ratchet (5) is supported by dual spring, spring (6) in described ratchet connecting sleeve (4) withstands the surface of ratchet (5) all the time, and the width of described ratchet (5) and the size of spring (6), quantity adapt.Compared with prior art, advantage of the present utility model is: increase support strength, increase ratchet expansionary force, makes oppositely locked more reliable, there will not be skidding, and increase driving torque.
Description
Technical field
The utility model relates to mechanical field, especially a kind of click driving mechanism.
Background technique
The unidirectional interval of the one that click driving mechanism is made up of ratchet and pawl
motionmechanism.It mainly comprises fork, ratchet and outer ratchet, and wherein rocking bar is motion input link, and ratchet is movement output component.The ratchet of click driving mechanism of the prior art is single spring supporting, and the width of ratchet is narrower, and little painstakingly, therefore support strength is poor.
Model utility content
The purpose of this utility model is to provide a kind of click driving mechanism, and its support strength is large, can strengthen ratchet expansionary force, makes oppositely locked more reliable, effectively can avoid skidding, and increase driving torque.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions, a kind of click driving mechanism, comprise fork, ratchet connecting sleeve, transmission shaft, end cap, connecting base and ratchet, it is characterized in that: in described ratchet connecting sleeve, be provided with spring, each ratchet is supported by dual spring, and the spring in described ratchet connecting sleeve withstands the surface of ratchet all the time, and the width of described ratchet and the size of spring, quantity adapt.
Further, described end cap and connecting base are screwed, and make transmission shaft laterally fixing, can not vibration.
Compared with prior art, the beneficial effects of the utility model are: by increasing the width of ratchet, adopt dual spring to support, the utility model increases support strength, increases ratchet expansionary force, make oppositely locked more reliable, there will not be skidding, and increase driving torque.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of click driving mechanism, comprise fork 9, ratchet connecting sleeve 4, transmission shaft 7, end cap 8, connecting base 3 and ratchet 5, spring 6 is provided with in described ratchet connecting sleeve 4, each ratchet 5 is supported by dual spring, spring 6 in described ratchet connecting sleeve 4 withstands the surface of ratchet 5 all the time, and the width of described ratchet 5 and the size of spring 6, quantity adapt.
Transmission principle of the present utility model is: in fork 9, four directions coordinates with the outer four directions of transmission shaft 7, fork 9 drives transmission shaft 7 to rotate, transmission shaft 7 is connected with ratchet connecting sleeve 4 by spline, thus drive ratchet connecting sleeve 4 to rotate, spring 6 in ratchet connecting sleeve 4 withstands the surface of ratchet 5 all the time, ratchet 5 is made to withstand draw-in groove in connecting base 3, connecting base 3 is driven to rotate, connecting base 3 drives main axis by connecting key 2, thus realize passing through leverage, make the little power of fork 9, by a series of mechanism, power is sent to main shaft, drive the rotation of main shaft, in addition, adopt due to the end cap 8 in the utility model and connecting base 3 and be screwed, make transmission shaft 7 laterally fixing, can not vibration.
During click work, when fork 9 rotates counterclockwise, spring 6 withstands ratchet 5, makes ratchet 5 acute ends withstand the interior buckle of connecting base 3, whole system is driven to complete transmission, after fork 9 forwards several angle to, when going back to clockwise, the oblique back side of ratchet 5 and the inclined-plane of connecting base can not form top power, then slid clockwise, now ratchet 5 and connecting base 3 can not form the transmission of power, thus system can not be driven to rotate, thus realize whole system all the time can along the rotation of a counterclockwise direction.
Due to the utility model compared with prior art add the width of ratchet 5, ratchet 5 adopts dual spring to support, therefore effectively increase the expansionary force of ratchet 5, make oppositely locked more reliable, there will not be skidding, and increase driving torque.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle, can also make some improvement, these improvement should be considered as protection domain of the present utility model.
Claims (2)
1. a click driving mechanism, comprise fork (9), ratchet connecting sleeve (4), transmission shaft (7), end cap (8), connecting base (3) and ratchet (5), it is characterized in that: in described ratchet connecting sleeve (4), be provided with spring (6), each ratchet (5) is supported by dual spring, spring (6) in described ratchet connecting sleeve (4) withstands the surface of ratchet (5) all the time, and the width of described ratchet (5) and the size of spring (6), quantity adapt.
2. click driving mechanism according to claim 1, is characterized in that: described end cap (8) and connecting base (3) are screwed.
