Among the figure: 1, jack cylinder; 2, headstock fixed body; 3, latch; 4, latch stay cord; 5, slide block; 6, first compression reseting spring; 7, pull bar; 8, pressing plate; 9, second compression reseting spring; 10, through hole; 11, latch pulling block; 12, latch stay cord head; 13, stopper slot; 14, stop screw; 15, jack; 16, boss is regulated in locking.
The specific embodiment
Angle regulating mechanism for locking like Fig. 1, Fig. 2, Fig. 3 and a kind of medical dolly swing handle shown in Figure 4; Comprise headstock fixed body 2; Inside one side of headstock fixed body 2 is provided with the through hole 10 that has two steps, on through hole 10 bottom stage, is provided with at least two latches 3 and is evenly distributed on the circumference of through hole 10 bottom stage, and latch 3 bottoms are provided with first compression reseting spring 6; Between each latch 3, be provided with latch pulling block 11; Latch pulling block 11 inside are provided with latch stay cord 4, on the intermediate step of through hole 10, are provided with jack cylinder 1,15 at least three of jacks on the jack cylinder 1 and being evenly distributed on the jack cylinder 1; Be provided with locking in the middle of the described headstock fixed body 2 and regulate boss 16; Regulate boss 16 inside in locking and be provided with slide block 5; Latch stay cord 4 is fixed on the slide block 5, and slide block 5 and locking are regulated between the boss 16 and is provided with second compression reseting spring 9, and locking is regulated boss 16 and is provided with pressing plate 8; Pressing plate 8 is connected with slide block 5 through pull bar 7, and pressing plate 8 is rotationally connected with pull bar 7; Described latch 3 is 5, and the jack 15 on the jack cylinder 1 is 6.
When in use, with the subordinate pressing plate 8 of pressing, pressing plate 8 drive pull bars 7 motions this moment, pull bar 7 drives slide block 5 motions; The slide block 5 second inner compression reseting springs 9 are compressed, and slide block 5 drives latch stay cord 4, and latch stay cord 4 drives 11 motions of latch pulling block through latch stay cord head 12; Latch pulling block 11 is left behind latch 3, and at this moment, the latch 3 first inner compression reseting springs 6 are compressed; Afterwards handle is rotated and confirm angle, pressing plate 8 is turned back the origin-location, compressed second compression reseting spring 9 is replied; Slide block 5 is back into the origin-location, and latch stay cord 4 unclamps, and this moment first, compression reseting spring 6 was replied; Latch 3 is released, but because the jack 15 on the jack cylinder 1 is 6, and latch 3 is 5; Wherein have a latch 3 to be pushed in the jack 15, all the other four are all blocked by jack cylinder 1, the process of so just accomplishing of once regulating the handle angle.
Because it is that 5 jacks 15 are 6 embodiment that the present invention has only given latch 3, and the adjusting angle of handle is 12 °, can regulate once for per 12 ° in the circumference; But the present invention only requires this a kind of mode of protection.
Provide definite adjusting angle below, select the application of formula of latch 3 and jack 15 numbers:
Wherein: α is the angle that the dolly handle rotates; M is the number of latch; N is the number of jack; K is the greatest common divisor of M and N.
For example: select 9 latches and 10 jacks, i.e. M=9, N=10, their greatest common divisor are 1, so the rotatable angle of handle is α=4 °.
Select 10 latches and 12 jacks, i.e. M=10, N=12, their greatest common divisor are 2, so the rotatable angle of handle is α=6 °.
Select 12 latches and 15 jacks, i.e. M=12, N=15, their greatest common divisor are 3, so the rotatable angle of handle is α=6 °.
There is above example to find out; We can consider to select the number of different latches and jack to realize, because adopted this mode according to the situation of required selection different angles; Can between 0～360 °, select suitable angle to realize; Available angular range is relatively wide and can select very little angle for use, can be used on some precision instruments, on the smaller instrument of required adjusting angle.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Except that the foregoing description, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
