Among the figure: 1, jack cylinder; 2, headstock fixed body; 3, latch; 4, latch stay cord; 5, slide block; 6, the first compression reseting spring; 7, pull bar; 8, pressing plate; 9, the 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
Such as Fig. 1, Fig. 2, the angle regulating mechanism for locking of Fig. 3 and a kind of turning handle of medical trolley shown in Figure 4, comprise headstock fixed body 2, inside one side of headstock fixed body 2 is provided with the through hole 10 with two steps, be provided with at least two latches 3 and be evenly distributed on the circumference of through hole 10 bottom stage in through hole 10 bottom stage, latch 3 bottoms are provided with the 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, intermediate step at through hole 10 is 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, slide block 5 and locking are regulated between the boss 16 and are provided with the second compression reseting spring 9, locking is regulated boss 16 and is provided with pressing plate 8, pressing plate 8 is connected with slide block 5 by 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, press pressing plate 8 with subordinate, pressing plate 8 drive pull bars 7 motions this moment, 5 motions of pull bar 7 band movable sliders, the second compression reseting spring 9 of slide block 5 inside is compressed, slide block 5 drives latch stay cord 4, latch stay cord 4 drives 11 motions of latch pulling block by latch stay cord head 12, latch pulling block 11 is left behind latch 3, and at this moment, the first compression reseting spring 6 of latch 3 inside is compressed, afterwards handle is rotated and determine angle, pressing plate 8 is turned back the origin-location, and compressed the second compression reseting spring 9 is replied, and slide block 5 is back into the origin-location, latch stay cord 4 unclamps, this moment first, compression reseting spring 6 was replied, latch 3 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 the Primary regulation handle angle of so just finishing.
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.
The below provides definite adjusting angle, selects 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 be according to the situation of required selection different angles, consider to select the number of different latches and jack to realize, because adopted this mode, can between 0～360 °, select suitable angle to realize, available angular range is relatively wide and can select very little angle, 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.In addition to the implementation, 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.
