Description
Technical field
This utility model relates to endoscopic technique field, particularly relates to a kind of endoscope fixation with steel wire governor motion.
Background technology
Usually, endoscope distal end bending section can toward bending up and down, it is mainly by the knob on rotation process handle, sprocket wheel is rotated and then drives chain end to carry out folding and unfolding, again because chain two ends are connected with steel wire, so steel wire just can pull front end bending section to bend up and down when rotary knob.
Steel wire is connected general chain tail end, welded pipe and pin three parts of passing through and realizes with chain, by pin through in welded pipe, steel wire rope is welded in welded pipe, is snapped into by the pin connecting welded pipe in chain tail end groove.But the steel wire degree of tightness adopting this kind of mode to connect can not adjust, the relative position that need carry out adjusting steel wire and chain tail end according to practical situation multiple welding steel wire when workman installs adjusts steel wire elasticity, too much welding operation will affect welded pipe quality, also waste workman's more time simultaneously, in addition after prolonged use, there is steel wire deformation in said structure, and then causes the decline of curved part of endoscope angular adjustment precision unavoidably.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, this utility model provides a kind of endoscope fixation with steel wire governor motion.
This utility model solves the technical scheme that its technical problem adopts:
A kind of endoscope fixation with steel wire governor motion, comprise operating portion, described operating portion comprises balanced handle section and vertical handle section, described balanced handle section is provided with wheel hub, described vertical handle section front end is provided with connecting axle, described wheel hub is connected by steel wire with between connecting axle, and wherein said steel wire is divided into two by middle position, is connected with the steel wire governor motion for regulating steel wire elasticity in the middle of it.
As the improvement of technique scheme, described steel wire governor motion comprise the adjusting nut that be arranged in parallel with described steel wire and by screw thread be installed on its two ends, respectively with the adjustment screw of both sides fixation with steel wire.
As the improvement of technique scheme, described adjustment screw is provided with fixation with steel wire hole, and one of them is set to positive tooth screw, another is set to anti-tooth screw.
As the improvement of technique scheme, described wheel hub, between connecting axle and described steel wire, be respectively arranged with elastic component.
As the improvement of technique scheme, described adjusting nut is provided with the concave surface being convenient to adjustment operation.
The beneficial effect that this utility model brings has:
This utility model is by steel wire governor motion, can be easy steel wire elasticity be regulated, and then realize the adjustment of endoscope bending section angle, its Stability Analysis of Structures and simple structure, improve the drawbacks such as production process in traditional structure is loaded down with trivial details, inconvenient maintenance, now extensively come into operation, be suitable for popularization.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is steel wire governor motion structural representations of the present utility model;
Accompanying drawing 3 is adjusting nut structural representations of the present utility model.
Detailed description of the invention
With reference to accompanying drawing 1 to accompanying drawing 3, this utility model is specially a kind of endoscope fixation with steel wire governor motion, and this mechanism relates generally to operating portion.Concrete, operating portion can be divided into balanced handle section 1 and vertical handle section 2, wherein balanced handle section 1 is provided with wheel hub 11, vertical handle section 2 front end is provided with connecting axle 21, wheel hub 11 is connected by steel wire with between connecting axle 21 simultaneously, in this utility model structure, steel wire is divided into two by middle position, and connects the steel wire governor motion 3 for regulating steel wire elasticity between two sections of steel wires.
Further, steel wire governor motion 3 comprise the adjusting nut 31 that be arranged in parallel with steel wire and by screw thread be installed on its two ends, respectively with the adjustment screw 32 of both sides fixation with steel wire, wherein adjustment screw 32 is provided with fixation with steel wire hole, and one of them being set to positive tooth screw, another is set to anti-tooth screw.When manual adjustments adjusting nut 31, two above-mentioned adjustment screw 32 will be mutually far away or close, thus realize the compensating roller of steel wire.
In addition, the wheel hub 11 in mechanism and steel wire, between connecting axle 21 and steel wire, all elastic component 4 can be set, increase elasticity and the buffering effect of structure.Meanwhile, adjusting nut 31 both sides also can arrange the concave surface 310 being convenient to adjustment operation.
In a word, this utility model is by steel wire governor motion 3, can be easy steel wire elasticity be regulated, and then realize the adjustment of endoscope bending section angle, its Stability Analysis of Structures and simple structure, improve the drawbacks such as production process in traditional structure is loaded down with trivial details, inconvenient maintenance, and, steel wire governor motion 3 can arrange parallel two groups, to improve steel wire regulating effect.
It should be noted that, the above is preferred embodiment of the present utility model, and this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
