Term as used herein " and/or " include the arbitrary and all of combination of one or more relevant Listed Items.
Refer to Fig. 1, the C-arm rotating mechanism 10 in present pre-ferred embodiments, regulate wheel 500 and second regulate wheel 600 including supporting seat 100, central shaft 200, slotted-plate 300, sliding block 400, first.
Seeing also Fig. 2, supporting seat 100 is used for fixing C-arm (not shown). One end of central shaft 200 is fixedly connected on supporting seat 100.
Slotted-plate 300 is fixed on supporting seat 100. Slotted-plate 300 is offered elongated hole 310. Central shaft 200 wears the middle part of slotted-plate 300, and central shaft 200 can drive slotted-plate 300 and supporting seat 100 to rotate.
One end of sliding block 400 is arranged in elongated hole 310. Slidably, and there is damping friction power in sliding block 400, so that under static state, sliding block 400 will not slide in elongated hole 310 because of factors such as the gravity of self in elongated hole 310 between the sidewall of sliding block 400 and elongated hole 310. The other end of sliding block 400 protrudes from slotted-plate 300.
Seeing also Fig. 3, first regulates wheel 500 is sheathed on central shaft 200, and relative centre axle 200 is rotatable. First regulates wheel 500 is provided with the first block 510 on the side of slotted-plate 300.
Second adjustment wheel 600 is rotatably connected at the first adjustment wheel 500 and is provided with on the side of the first block 510. Second adjustment wheel 600 and the first adjustment wheel 500 are arranged concentrically. Second regulates wheel 600 is provided with the second block 610 on the side of slotted-plate 300. Regulate, by regulating the second adjustment wheel 600 and first, the relative motion taking turns 500, the relative position of the first block 510 and the second block 610 can be changed.
First block 510 regulates radius wheel 600 residing for more than the second block 610 second at the first radius regulated residing for wheel 500. It is equal at the first radius regulated residing for wheel 500 that elongated hole 310 keeps away the radius residing for the one end in frid 300 center of circle and the first block 510, and elongated hole 310 is equal at the second radius regulated residing for wheel 600 near the radius residing for the one end in slotted-plate 300 center of circle and the second block 610.
Specifically in the present embodiment, the first block 510 and the second block 610 are cylindrical structural. Elongated hole 310 keeps away radius residing for the one end in frid 300 center of circle and elongated hole 310 difference near the radius residing for the one end in slotted-plate 300 center of circle equal to the radius sum of the first block 510 and the second block 610.
Wherein, seeing also Fig. 4, central shaft 200 drives slotted-plate 300 to rotate so that the first block 510 or the second block 610 can contact with sliding block 400.
See also Fig. 5, central shaft 200 drive slotted-plate 300 and supporting seat 100 along Fig. 5 rotationally clockwise, supporting seat 100 drive be loaded into C-arm thereon rotate. Sliding block 400 contacts with the first block 510. First block 510 promotes sliding block 400 to elongated hole 310 near the one end in slotted-plate 300 center of circle, and is separated with sliding block 400. Now, sliding block 400 is residing on slotted-plate 300 radius and the second block 610 are identical at the second radius regulated on wheel 600. Slotted-plate 300 is rotated further, so that the second block 610 supports with sliding block 400, owing to sliding block 400 also offsets with the end face of elongated hole 310, therefore slotted-plate 300 now cannot be rotated further, with spacing slotted-plate 300, and then define the rotation of the C-arm being loaded on supporting seat 100.
Or, central shaft 200 drives slotted-plate 300 and supporting seat 100 counter clockwise direction along Fig. 5 to rotate, and supporting seat 100 drives and is loaded into C-arm thereon rotation. Sliding block 400 contacts with the second block 610. Second block 610 promotes sliding block 400 to elongated hole 310 to keep away the one end in frid 300 center of circle, and is separated with sliding block 400. Now, sliding block 400 is residing on slotted-plate 300 radius and the first block 510 are identical at the first radius regulated on wheel 500.Slotted-plate 300 is rotated further, so that the first block 510 supports with sliding block 400, owing to sliding block 400 also offsets with the end face of elongated hole 310, therefore slotted-plate 300 now cannot be rotated further, with spacing slotted-plate 300, and then define the rotation of the C-arm being loaded on supporting seat 100.
