Specific embodiment
Below in conjunction with attached drawing, specific embodiments of the present invention will be described in detail.
Embodiment one：Referring to Fig. 1 and Fig. 2, a kind of two-way non-return device, including actively shift fork component and driven shift fork group
Part, 3 actively shift fork blocks 2 that the actively shift fork component includes shifting fork disc 1 and is circumferentially uniformly arranged on shifting fork disc 1,
The driven shift fork component includes with the driven shift fork casing 3 of 1 axis of shifting fork disc setting and setting in 3 outer wall of driven shift fork casing
On 3 driven shift fork blocks 4, the actively shift fork block 2 and driven shift fork block 4 equidistant staggeredly interval point on the same circumference
Cloth, and actively shift fork block 2 is identical with the radial height of driven shift fork block 4, adjacent actively shift fork block 2 and driven shift fork block 4 it
Between 3 outer wall of driven shift fork casing on be provided with arc thrust groove 5, be provided with cylindrical roller 6 in the arc thrust groove 5,
Thrust spring 7 is provided between cylindrical roller 6 and driven shift fork block 4,4 two sides of driven shift fork block offer and thrust bullet
The matched spring standing groove 9 of spring 7.
Fixed outer ring 8, fixed outer ring 8 and actively shift fork block are also arranged in actively shift fork block 2 and 4 outside of driven shift fork block
Equal glade plane space cooperation between 2 and driven shift fork block 4, when cylindrical roller 6 be in arc 5 slot bottom of thrust groove, cylindrical roller 6 and
Fixed 8 gap of outer ring separation, when cylindrical roller 6 is in arc 5 groove top of thrust groove, the patch corresponding with fixed outer ring 8 of cylindrical roller 6
It closes.
The working principle of the present embodiment is：
In use, driven shift fork casing needs to bear always the load of counterclockwise or clockwise single direction
Torque, and operator needs to rotate clockwise or counterclockwise by shift fork disk, makes fixed outer ring, driven shift fork at this time
The rotation for being separated from each other between casing, cylindrical roller, and then driven shift fork casing being driven to synchronize；When acting on shifting fork disc
Active force disappear after, under the action of load torque, fixed outer ring, driven shift fork casing, cylindrical roller and thrust spring it
Between interaction so that whole device carry out it is self-locking, prevent rotation under the action of load torque of driven shift fork casing, thus
It realizes Double-directional rotary and two-way check is self-locking.
The load torque suffered by the driven shift fork casing in two-way non-return device be counterclockwise for, to transmission process
In each component stress variation analyzed：
When not having acting energy torque on shifting fork disc, the load torque counterclockwise on driven shift fork casing drives driven group
Fork casing rotates counterclockwise, and is now placed in the cylindrical roller on the right side of actively shift fork block by the fixation outer ring reversed with thrust spring
Active force, the cylindrical roller on the right side of actively shift fork block slides into arc thrust groove slot bottom, so that being located on the right side of actively shift fork block
Cylindrical roller, fixed outer ring and the separation of driven shift fork shell clearance be slidably matched；And it is located at the cylinder rolling on the left of actively shift fork
Son is prevented by the active force in the same direction with thrust spring so that cylindrical roller, fixed outer ring and driven shift fork casing are locked
Driven shift fork casing further rotating counterclockwise under the action of load torque.
When shifting fork disc effect has clockwise dynamic torque, actively shift fork block pushes the circle being located on the right side of actively shift fork block
Column roller overcomes the jacking force of thrust spring, so that cylindrical roller is slid by the groove top of arc thrust groove into slot bottom, cylinder at this time
Gap separates between roller and driven shift fork casing and fixed outer ring；At the same time, positioned at the circle in the left side of actively shift fork block
Active force of the column roller by fixed outer ring is also slid by the groove top of arc thrust groove to overcome the jacking force of thrust spring
Enter slot bottom, in the process, although the cylindrical roller on the left of actively shift fork block is bonded with fixed outer ring, certainly by cylindrical roller
Opposite sliding between the rolling of body and cylindrical roller and fixed outer ring, without turning clockwise to driven shift fork casing
It is dynamic to cause to constrain, and then overcome the load torque counterclockwise acted on driven shift fork casing so that driven shift fork casing with
Shifting fork disc rotates clockwise.
When shifting fork disc effect has dynamic torque counterclockwise, the stress condition of each cylindrical roller in operational process with dial
Fork disk be subject to dynamic torque clockwise when stress condition just on the contrary, and each cylindrical roller will not be to driven shift fork set
The rotation of pipe causes to constrain, under shifting fork disc and load torque collective effect counterclockwise, so that driven shift fork set
Pipe is rotated counterclockwise with shifting fork disc.
Embodiment two：Referring to figures 1-3, a kind of two-way check hand including two-way non-return device described in embodiment one
Device is shaken, further includes hand-operated device shell 10, rear bottom plate 11, reel 12, coiling steel wire 13 and rotational handle 14, wherein outside hand-operated device
The material of shell and rear bottom plate is aluminium alloy.
The shifting fork disc 1 is axial to be provided with actively shift fork shaft 15, actively shift fork shaft 15 and 14 phase of rotational handle
Match, the driven shift fork casing 3 is slidably located in actively shift fork shaft 15, and the fixation of reel 12 is set in driven
On shift fork casing 3, spring bearing 16, driven shift fork casing 3 are provided between 3 inner end of driven shift fork casing and fixed outer ring 8
Bearing support 16 is also equipped between outer end and hand-operated device shell 10, fixed outer ring 8 is fixedly connected with rear bottom plate 11.
According to the different demands of client in the application, can be arranged side by side in hand-operated device shell 10 there are two or more
Reel 12, matching is connected with two-way non-return device on each reel 12.
The working principle of the present embodiment is：
Reel always by the load torque active force of clothes-horse, i.e. born by clothes-horse always by driven shift fork casing
Torque active force is carried, when needing the lifting of clothes-horse, by stirring rotational handle, so that actively shift fork shaft is clockwise or inverse
Hour hands rotation drives take-up or the unwrapping wire of reel to shed after the completion of clothes-horse lifting by the transmission of two-way non-return device
The active force of rotational handle, two-way non-return device occurs self-locking at this time.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
Improvement is both fallen in the range of claimed invention.The present invention claims protection scope by appended claims and its
Equivalent defines.
