Fig. 2 is the structural representation that the present invention is fixed on side rails;
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1 to Figure 3, the clamping force enlarger of a kind of shaftless fast clamp of the present invention and release comprises upper clipping claw 1 and lower claw 2, and the same side of upper clipping claw 1 and lower claw 2 is provided with hook-shaped portion 3, for being stuck in the side rails of operation table.The another side of upper clipping claw 1 is also provided with bandage interface 4, for being connected with elastic bandage 18.
Upper clipping claw 1 and lower claw 2 are interconnected by a shaftless pivot structure.In the present embodiment upper clipping claw 1 lower surface on stretch out an inclined arm 20 obliquely, the top of inclined arm 20 arranges a columniform pivotal axis portion 5, have a groove 6 extended along pivotal axis portion 5 length direction between pivotal axis portion 5 and lower claw 2, the cross section of groove 6 is the circular arc coaxial with pivotal axis portion 5; Correspondingly descend the upper surface of claw 2 arranges the pivot part 7 that a cross section coordinates with groove 6 shape, pivot part 7 inlay card in groove 6, thus makes pivotal axis portion 5 become pivotal axis between upper clipping claw 1 and lower claw 2.Avoid and use other parts as the structure of pivotal axis, decrease number of parts.The girth of groove 6 cross section accounts for 1/4 ~ 3/8 of the girth of its place circle, can limit upper clipping claw 1 and lower claw 2 directly pivoting angle like this, avoid it excessive.The both ends of the surface in pivotal axis portion 5 are provided with screwed hole 8, the two ends in pivotal axis portion 5 are all provided with disc-shaped seal lid 10 by trip bolt 9, depart from from the direction at two ends, pivotal axis portion 5 to avoid upper clipping claw 1 and lower claw 2.Certainly, also said structure can be changed over and pivotal axis portion 5 and groove 6 are set on lower claw 2, upper clipping claw 1 arrange pivot part 7, equally also can realize above-mentioned purpose.
In the present embodiment, further improves the structure of bandage interface 4.Bandage interface 4 arranging bandage groove 11, passing for holding bandage 18.The one end open 12 of bandage interface 4, to facilitate bandage 18 to pass, and facilitates bandage 18 still to can be passed through opening 12 when tensioning to come off from bandage interface 4.The other end of bandage interface 4 is arranged on upper clipping claw 1 by screw 13 pivot, and opening 12 and screw 13 are all positioned on the vertical line of bandage groove 11.By bandage interface 4 is pivotally connected on claw, angle can be adjusted according to binding position, make bandage 18 remain that front is bundled in patient, avoid the position because of binding top or make bandage 18 tilt on the lower, cause contact surface little to patient and produce painful.
Lower claw 2 is provided with through jogger hole 14, the push rod 15 be resisted against on upper clipping claw 1 is provided with in jogger hole 14, also be threaded the screw 21 of push rod 15 shutoff in jogger hole 14 in jogger hole 14, between push rod 15 and screw 21, be provided with spring 16.Upper clipping claw 1 is arranged the protuberance 17 of an arc, push rod 15 is resisted against on protuberance 17, and protuberance 17 is positioned at the both sides in pivotal axis portion 5 with the hook-shaped portion 3 of upper clipping claw 1.Under push rod 15 and spring 16 are used in the state that bandage unclamps, still upwards push up upper clipping claw 1, its direction to operation table side rails is tilted, formed and clamp, avoid it to come off.
In use, one end of bandage 18 is fixed on operation table (not shown) in the present invention, and the other end is through bandage groove 11, and upper clipping claw 1 and lower claw 2 open, and clamp on the side rails 19 of operation table.The tightening force of bandage 18 drives upper clipping claw 1 to rotate, thus clamping side rails 19 forms self-locking.When unclamping, only need the opening 12 of bandage 18 from bandage groove 11 to pass through, can untie, the width of opening 12 is less than 1/3 of the width of bandage 18, easily departs from voluntarily too greatly, too little then not easily manual disengaging.
Above according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, related personnel in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine technical scope according to right.
