The adpting flange of 106 and the adpting flange exporting shifting block 103 are close to end face before and after the cylinder of described lock sleeve 104, and institute
The adpting flange stating the input adpting flange of shifting block 106, lock sleeve 104 and output shifting block 103 is co-located on described fixed frame
In cylinder, and by fixed frame limit lock sleeve axial, move radially.The connecting shaft of described input shifting block 106 stretches out in solid
Determining that the cylinder of frame is outer and power shaft 132 as whole passive self-locking device, the connecting shaft of described output shifting block 103 stretches out in solid
Outside determining the flange connection surface of frame and as the output shaft 131 of whole passive self-locking device.
Now the self-locking operation principle of passive self-locking device of the present utility model is specifically described as follows.When input shifting block 106,
During output shifting block 103 the most non-moment input, latch 105 is compressed to the right by spring members, as shown in Figure 2.Its upper and lower summit
It is resisted against on the inner surface of lock sleeve 104, and owing to the distance between upper and lower summit is less than the straight of the shaft section of lock sleeve 104
Footpath, in the semicircle at the slide block place of the input shifting block 106 that this upper and lower summit is all resisted against in lock sleeve；When input shifting block 106
Clockwise or counterclockwise during input torque, as shown in Figure 4,5, the latch 105 compression bullet in direction towards output shifting block will be promoted
Spring parts (as a example by turriform helical spring 102), the turriform helical spring 102 as elastomeric element will occur under compression
Move to left, thus latch 105 also moves to left towards the direction of output shifting block so that its upper and lower summit departs from the inner circle of lock sleeve 104
Post surface, the most described latch becomes parts free to rotate, thus the moment of torsion inputting the slide block of shifting block 106 can be through
Latch 105 is delivered to export the slide block of shifting block 103 smoothly, realizes up time freely via the output shaft of output shifting block 103
Pin or rotate counterclockwise；Otherwise, as shown in Figure 6, when exporting shifting block 103 and being loaded reversed load, either clockwise or
Anticlockwise load, promotion latch is continued to move to right by the slide block of output shifting block 103, but because of the summit up and down of latch
Being close to the inner cylinder face of lock sleeve the most under the action of the spring, moment to the right can only make latch be locked to further
In lock sleeve, it is impossible to mobile.And then freely rotatable and torque transmission cannot be realized so that load on output shifting block 103 is reverse
Load cannot be delivered to input on shifting block, it is achieved that passive type self-locking, and finally the moment of torsion through power shaft 132 input can be smoothly
It is delivered on output shaft 131, but but cannot be delivered on power shaft through the moment of torsion of output shaft Opposite side loading, it is ensured that unidirectional biography
Dynamic.
Can be combined with the bearing outside lock sleeve as the alternative embodiment of another kind, output shifting block or input shifting block,
Thus realize and the rotating coaxially of lock sleeve.Therefore the shape of its slide block also need not be confined to the inner periphery shape of lock sleeve.
The output shifting block of this utility model innovative design, latch and input shifting block achieve a kind of brand-new from lock side
Case, described passive self-locking device can be good at being applied in decelerator.Combination is given below and has quilt described in the utility model
The decelerator of dynamic self-locking device, as described in accompanying drawing 3, described decelerator includes deceleration transmission assembly 2 and above-mentioned passive self-locking dress
Putting 1, concrete described deceleration transmission assembly 2 includes the assembly devising two different speed ratios of innovation, wherein the first assembly bag
Including the first power transmission shaft 201 and the first travelling gear 203 being arranged on the first power transmission shaft 201, the second assembly includes the second biography
Moving axis 202 and the second travelling gear 204 being arranged on second driving shaft 202, the first assembly and the second assembly are by front card
Dish 212 and rear chuck 213 link together, and the first concrete power transmission shaft 201 and second driving shaft 202 be arranged in parallel, described before
Chuck 212 includes flange surface and two sleeves, and the front end of the first power transmission shaft 201 and second driving shaft 202 inserts front card respectively
In two sleeves of dish, described rear chuck 213 is provided with two through holes, after the first power transmission shaft 201 and second driving shaft 202
End is each passed through two through holes of described rear chuck 213, the most described first travelling gear 203 and the second travelling gear 204 phase
Mesh together mutually, and the number of teeth of described first travelling gear 203 is the half of the second travelling gear, so use the second transmission
Axle 202 is not than using the first power transmission shaft 201 laborsaving 1/2nd, and the benefit so designed is, that stint strength or have quick rotation
Require can be input to rotational power on the first power transmission shaft 201, think that rotational power can be input to by labour-saving second
On power transmission shaft 202, deceleration transmission selects more various.Described deceleration transmission assembly 2 also includes coupling wheel 205, described coupling
Close gear 205 to be engaged on described first travelling gear 203 or described second travelling gear 204, be preferably engaged in described the
On two travelling gears 204, the power shaft 132 of described passive self-locking device 1, the input being wherein installed in fixed frame is dialled
The connecting shaft of block 106 is fixedly connected on described coupling wheel 205, and preferred described power shaft 132 is connected to described by flat key
The center through hole of coupling wheel 205, thus after retarding power provides the first power transmission shaft, after gear transmission reducing effect
It is delivered on coupling wheel 205, then input power is delivered to input in the connecting shaft of shifting block 106, finally by coupled gear 205
Transfer power to export on the output shaft of shifting block through input shifting block 106, it is achieved the deceleration transmission of input power, avoid simultaneously
The reverse power that output shaft loads drives deceleration transmission assembly to rotate backward, it is achieved that the single retarded of decelerator and reverse self-locking
Process, and described passive self-locking device can combine easily with on deceleration transmission assembly, and will not cause reducer structure
Great change.
Additionally, the above-mentioned decelerator being combined with passive self-locking device also can be installed in the wheel of manual wheelchair and car body it
Between.So when going up a slope, manual wheelchair advances, when unclamping hands, even if inapplicable brake gear, even if not using brake wheelchair
Also will not retreat, provide one more heavily ensure for taking people.
Finally it is pointed out that and the utility model proposes passive self-locking device, and be given combination have described passive from
The decelerator of locking device, but the application of passive self-locking device described in the utility model is not limited to that, and it can be applicable to appoint
What has device or the mechanism of reversely passive self-locking requirement, belongs to a kind of brand-new self-locking mechanism, and having wide marketing should
Use prospect.
