Specific embodiment
- Fig. 2 referring to Fig.1, the utility model a kind of rope control optical axis telescoping mechanism, including optical axis 1, for for
Optical axis 1 provides the connecting component 2 of motion path, for driving optical axis 1 to carry out the traction element of back and forth movement and lead for driving
Draw the power source 4 that component drives optical axis 1 to carry out back and forth movement, traction element includes traction rope 3, and power source 4 passes through traction rope
Son 3 is connected with optical axis 1, and the direction of 4 output power of power source and the axial direction of optical axis 1 are parallel to each other；4 pairs of traction ropes of power source
3 apply the active force parallel with the axial direction of optical axis 1, so that the both ends of traction rope 3 are shunk and stretched respectively, thus band
Dynamic optical axis 1 carries out back and forth movement along connecting component 2.Specifically, it is connected by traction rope 3 with optical axis 1 due to power source 4
It connects, and the direction of 4 output power of power source and the axial direction of optical axis 1 are parallel to each other, therefore when 4 pairs of traction ropes 3 of power source are applied
When adding the active force parallel with the axial direction of optical axis 1, the both ends of traction rope 3 can be shunk and be stretched respectively, to drive
Optical axis 1 carries out back and forth movement along connecting component 2, to provide a kind of simple and practical scheme for the flexible of axis.Due to this
The optical axis telescoping mechanism of utility model is only by optical axis 1, connecting component 2, traction rope 3 and power source 4 and simply combining
It constitutes, therefore has the characteristics that structure is simple and easy to implement, also, optical axis 1, connecting component 2, traction rope 3 and power source 4 are
Conventional simple components, therefore its fabrication cycle is short.So the optical axis telescoping mechanism of the utility model, is not only simple in structure easily
Realize, and fabrication cycle is short, is applicable among small organization, thus for axis it is flexible provide it is a kind of fairly simple practical
Scheme.
Wherein ,-Fig. 2, the both ends of optical axis 1 are separately provided for facilitating the concave ring of the fixation of traction rope 3 referring to Fig.1
11, traction rope 3 is connected in the top of optical axis 1 across optical axis 1 and the binding of concave ring 11 by power source 4.Specifically, 11 energy of concave ring
Traction rope 3 is enough facilitated to be fixed on the both ends of optical axis 1.Traction rope 3 is fixed on the both ends of optical axis 1, Ke Yiyou
A variety of fixed forms, such as two circular holes are respectively set at the both ends of optical axis 1, when traction rope 3 needs to be fixed on the two of optical axis 1
When on end, the both ends of traction rope 3 are each passed through two circular holes first, then by distinguishing at the both ends of traction rope 3
Knot or the both ends of traction rope 3 are wrapped on the both ends of optical axis 1, can realize that a traction rope 3 is fixed
In the operation of optical axis 1, still, this mode is not easy enough, and is more troublesome.For example, if using across circular hole and carrying out
The mode of knotting, then just needing the diameter very little of circular hole, which not only improves the manufacture difficulties of optical axis 1, and traction rope
Son 3 passes through tiny circular hole and is also required to stable operation, therefore can extend the time of production.For another example, if using across circle
Hole and the mode being wound, that is also required to carry out the operation that traction rope 3 passes through circular hole, so that operation is not easy enough.
And in the present embodiment, since concave ring 11 is respectively set at the both ends of optical axis 1, so, it only needs directly the both ends of traction rope 3 point
It is not bundled among concave ring 11, to substantially increase the time of production, and the processing of optical axis 1 is also easy to realize.
Wherein ,-Fig. 2, power source 4 are provided with the shaft 41 for outputting torsion referring to Fig.1, and shaft 41 and optical axis 1 are mutual
Vertically, traction rope 3 is wound on shaft 41 and draws the both ends of rope 3 and bundle respectively with the both ends of optical axis 1 and connects.Tool
Body, when the optical axis telescoping mechanism of the utility model needs larger volume, power source 4 can use motor；When this is practical new
When the optical axis telescoping mechanism of type needs smaller size smaller, power source 4 can use motor.So the optical axis of the utility model is flexible
The structure of mechanism is simple, can according to actual different use demands flexible setting.Due to the shaft 41 and optical axis of power source 4
1 is mutually perpendicular to, and draws after rope 3 is wrapped on shaft 41, and both ends bundle with the both ends of optical axis 1 connect respectively, because
This, when the shaft 41 of power source 4 is rotated, traction rope 3 can be moved with the rotation of shaft 41, at this point, leading
One end of messenger 3 is shunk, and position compensation occurs for the other end, to drive the optical axis 1 of corresponding one end to be shunk, so that another
The optical axis 1 at end stretches out, so that optical axis 1 is able to carry out movement；And when the shaft of power source 4 41 is inverted, optical axis 1 then can court
Opposite direction moved, to realize the round-trip telescopic movable of optical axis 1.
Wherein ,-Fig. 2, traction element further include the roller 31 for increasing frictional force referring to Fig.1, and roller 31, which is set in, to be turned
On axis 41, traction rope 3 is wound on roller 31.Specifically, roller 31 can be improved its rubbing between traction rope 3
Power is wiped, so that traction rope 3 can timely respond to the rotation of shaft 41.Since roller 31 is fixed on shaft 41 simultaneously energy
It is rotated synchronously with shaft 41, and draws rope 3 and be wound on roller 31, therefore when roller 31 as shaft 41 rotates synchronously
When, the frictional force between roller 31 and traction rope 3 enables traction rope 3 to be moved therewith, to realize traction rope
The both ends of son 3 are shunk and are stretched out respectively, so as to drive optical axis 1 to carry out round-trip stretching motion.In the present embodiment, it leads
Messenger 3 winds 4-5 circle on roller 31, to make can have enough frictions between roller 31 and traction rope 3
Power and be able to drive optical axis 1 carry out stretching motion.
Wherein ,-Fig. 2 referring to Fig.1, connecting component 2 are provided with for providing the through-hole of motion path for optical axis 1, through-hole it
In be provided with bearing 21, optical axis 1 passes through bearing 21 and is set among connecting component 2.Specifically, the bearing 21 in the present embodiment can
To use oilless bearing or linear bearing, but it is optimal using oilless bearing.Oilless bearing and linear bearing, which can play, to be mentioned
The effect of the sport efficiency of high optical axis 1, but since the volume of oilless bearing is smaller compared with the volume of linear bearing, oil-free axis
The requirement for more meeting small-scale structure is held, therefore, oilless bearing is the optimal selection of the present embodiment.
Wherein ,-Fig. 2, connecting component 2 are additionally provided with the support portion 22 for carrying power source 4, through-hole setting referring to Fig.1
In one end of support portion 22.Specifically, support portion 22 can carry power source 4, and connecting component 2 and power source 4 are tied
An entirety is synthesized, so as to effectively save spatial volume, to meet the production requirement of small-scale structure.
In the present embodiment, the component used is all fairly simple, only motor, rope, optical axis, roller and oil-free axis
It holds, the component for not needing largely to process, fabrication cycle is shorter.For small organization, if only requiring, optical axis has flexible energy
Power, without the requirement of other loads, it is possible to replace motor using the smaller motor of volume, so as into one
Step reduces the volume of optical axis telescoping mechanism.
Be above to the utility model it is preferable implementation illustrated, but the utility model be not limited to it is above-mentioned
Embodiment, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Deformation or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
