Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is elaborated.
Embodiment one: seeing Fig. 1 and Fig. 2, a kind of two-way non-return device, including actively pull-fork assembly and driven shift fork group
Part, described active pull-fork assembly includes shifting fork disc 1 and the most uniform 3 be arranged on shifting fork disc 1 actively shift fork block 2,
Described driven pull-fork assembly includes the driven shift fork sleeve pipe 3 arranged with shifting fork disc 1 axle and is arranged on driven shift fork sleeve pipe 3 outer wall
On 3 driven shift fork blocks 4, described active shift fork block 2 and driven shift fork block 4 equidistant staggered interval point on same circumference
Cloth, and actively shift fork block 2 is identical with the radial height of driven shift fork block 4, adjacent active shift fork block 2 and driven shift fork block 4 it
Between driven shift fork sleeve pipe 3 outer wall on be provided with arc thrust groove 5, be provided with cylindrical roller 6 in described arc thrust groove 5,
Being provided with thrust spring 7 between cylindrical roller 6 and driven shift fork block 4, described driven shift fork block 4 both sides offer and thrust bullet
The spring placing trough 9 of spring 7 coupling.
Fixing outer ring 8 also it is arranged with, fixing outer ring 8 and actively shift fork block outside active shift fork block 2 and driven shift fork block 4
Between 2 and driven shift fork block 4, equal glade plane space coordinates, when cylindrical roller 6 is in arc thrust groove 5 bottom land, cylindrical roller 6 with
Fixing gap, outer ring 8 separates, when cylindrical roller 6 is in arc thrust groove 5 groove top, and cylindrical roller 6 patch corresponding with fixing outer ring 8
Close.
The operation principle of the present embodiment is:
In use, driven shift fork sleeve pipe needs the load bearing counterclockwise or clockwise single direction to turn round all the time
Square, and operator need to be rotated clockwise or counterclockwise by shift fork dish, now make fixing outer ring, driven shift fork set
It is separated from each other between pipe, cylindrical roller, and then drives driven shift fork sleeve pipe to carry out the rotation synchronized；When acting on shifting fork disc
After active force disappears, under the effect of load torque, fixing outer ring, driven shift fork sleeve pipe, between cylindrical roller and thrust spring
Interaction make whole device carry out self-locking, prevent driven shift fork sleeve pipe rotation under the effect of load torque, thus real
Double-directional rotary and two-way check self-locking are showed.
The load torque suffered by driven shift fork sleeve pipe in two-way non-return device be counterclockwise as a example by, to transmission process
In each parts stress change be analyzed:
When not having acting energy moment of torsion on shifting fork disc, the load torque counterclockwise on driven shift fork sleeve pipe drives driven shift fork set
Pipe rotates counterclockwise, and is now placed in cylindrical roller the making by the fixing outer ring reverse with thrust spring on the right side of active shift fork block
Firmly, actively the cylindrical roller sliding on the right side of shift fork block enters arc thrust groove bottom land so that be positioned at the circle on the right side of active shift fork block
Post roller, fixing outer ring separate with driven shift fork shell clearance and are slidably matched；And it is positioned at the cylindrical roller on the left of active shift fork, its
By with thrust spring active force in the same direction so that cylindrical roller, fixing outer ring and driven shift fork sleeve pipe are locked, prevent driven group
Fork sleeve pipe rotating counterclockwise further under the effect of load torque.
When shifting fork disc effect has clockwise dynamic torque, actively shift fork block promotes the circle being positioned on the right side of active shift fork block
Post roller, overcomes the jacking force of thrust spring so that cylindrical roller is entered bottom land by the groove top sliding of arc thrust groove, now cylinder
Between roller with driven shift fork sleeve pipe and fixing outer ring, equal gap separates；Meanwhile, the circle in the actively left side of shift fork block it is positioned at
Post roller is by the active force of fixing outer ring, thus overcomes the jacking force of thrust spring, also by the groove top sliding of arc thrust groove
Enter bottom land, in the process, although actively the cylindrical roller on the left of shift fork block is fitted with fixing outer ring, but by cylindrical roller certainly
Relative slip between the rolling of body and cylindrical roller and fixing outer ring, without turning clockwise driven shift fork sleeve pipe
Dynamic cause constraint, and then overcome the load torque counterclockwise acted on driven shift fork sleeve pipe so that driven shift fork sleeve pipe with
Shifting fork disc rotates clockwise.
When shifting fork disc effect has dynamic torque counterclockwise, the stressing conditions of each cylindrical roller in running with dial
During the dynamic torque clockwise that fork dish is subject to, stressing conditions is just contrary, and each cylindrical roller also will not be to driven shift fork set
The rotation of pipe causes constraint, under the common effect that shifting fork disc and load torque are counterclockwise, so that driven shift fork set
Pipe rotates counterclockwise with shifting fork disc.
Embodiment two: see Fig. 1-Fig. 3, the two-way check hands of a kind of two-way non-return device included described in embodiment one
Shake device, also include hand-operated device shell 10, rear base plate 11, reel 12, coiling steel wire 13 and turning handle 14, wherein outside hand-operated device
The material of shell and rear base plate is aluminium alloy.
Described shifting fork disc 1 is axially arranged actively shift fork rotating shaft 15, actively shift fork rotating shaft 15 and turning handle 14 phase
Joining, described driven shift fork sleeve pipe 3 is slidably located in actively shift fork rotating shaft 15, and described reel 12 fixed cover is located at driven
On shift fork sleeve pipe 3, between and fixing outer ring 8 inner at driven shift fork sleeve pipe 3, it is provided with spring bearing 16, driven shift fork sleeve pipe 3
Being also equipped with block bearing 16 between outer end and hand-operated device shell 10, fixing outer ring 8 is fixing with rear base plate 11 to be connected.
Different demands according to client in the application, can be arranged side by side two or more in hand-operated device housing 10
Reel 12, on each reel 12, all coupling is connected with two-way non-return device.
The operation principle of the present embodiment is:
Reel is all the time by the load torque active force of clothes-horse, and the most driven shift fork sleeve pipe is turned round by the load of clothes-horse all the time
Square active force, when needing the lifting of clothes-horse, by agitation turning handle so that actively shift fork rotating shaft is clockwise or counterclockwise
Rotate, by the transmission of two-way non-return device, drive take-up or the unwrapping wire of reel, after clothes-horse has lifted, shed rotation
The active force of handle, the most two-way non-return device generation self-locking.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
The personnel simply present invention it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description
Principle, the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, these change and
Improvement both falls within the range of claimed invention.The protection domain of application claims by appending claims and
Equivalent defines.
