Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Seeing shown in Fig. 1 Fig. 5, a kind of single former multi-stage mechanical transmission stretching structure in the present embodiment, including overlapping successively
1, two grades of telescopic tubes 2 of the one-level telescopic tube connect and three grades of telescopic tubes 3, described one-level telescopic tube 1 two ends are fixed on one
Before level after axle bed 4 and one-level on axle bed 5, before before described one-level, after axle bed 4 and one-level, the bottom of axle bed 5 is respectively arranged with one-level
Sprocket wheel 7 after sprocket wheel 6 and one-level, is provided with primary transmission chain 8 before described one-level on sprocket wheel 7 after sprocket wheel 6 and one-level, and described one
Level driving chain 8 is positioned at the lower inside of one-level telescopic tube 1, and wherein before one-level, sprocket wheel 6 is taken turns and outside electricity as motive power
Machine is connected, being rotated by thus drive primary transmission chain 8 to rotate, in the upper half of described one-level transmission chain 8 at motor
Part has one section of breach, and this breach is connected, after described first connecting plate 9 and two grades of telescopic tubes 2 by the first connecting plate 9
End is fixing to be connected, and when straight forward movement under primary transmission chain is in driven by motor, drives two grades of telescopic tubes 2 to be stretched by one-level
Heat-Shrinkable Tubings 2 is internal protruding, thus realizes two grades and stretch；
Sprocket wheel 11 after sprocket wheel 10 and two grades before the front and back end, inside of described two grades of telescopic tubes 2 is provided with two grades, described two
It is provided with secondary transmission chain 13 on sprocket wheel 11 after sprocket wheel 10 and two grades, sprocket wheel 11 after sprocket wheel 10 and two grades before described two grades before level
Low portion be exposed to the bottom of two grades of telescopic tubes 2 and make the latter half of secondary transmission chain 13 be positioned at two grades of telescopics
The outside of pipe 2, has another breach in the latter half of described secondary transmission chain 13, and this breach is by the second connecting plate 14 even
Connecing, described second connecting plate 14 is fixing with the bottom of one-level telescopic tube 1 after passing the notch bottom two grades of telescopic tubes 2 to be connected
Connect, when two grades of telescopic tube straight forward movement of primary transmission chain-driving, the secondary transmission chain in two grades of telescopic tubes
Should also be as in theory travelling forward, but be connected owing to the second connecting plate and one-level telescopic tube are fixing, now, second grade transmission chain
The straight forward movement of bar is converted into rotation, and the top half of described secondary transmission chain 13 is by the 3rd connecting plate 15 and three
The rear end of level telescopic tube 3 is fixing to be connected, and therefore realizes three grades of three grades of telescopic tubes 3 under the rotation of secondary transmission chain 13
Flexible.By that analogy, by the setting of said structure, it is possible to achieve stretching of level Four, Pyatyi or more stages, and have only to
Realize under the driving of one power source motor.
Such scheme is accomplished that sleeve pipe trackless equivalent stretching motion at different levels, and i.e. two grades telescopic tubes 2 stretch out how many distances,
Secondary transmission chain 13 also stretches out how many distances so that three grades of telescopic tube 3 equivalent stretch out identical distance, in some situation
Under, load of the distance that three grades of telescopic tubes stretch out too much its carrying just reduces, be easily caused three grades of telescopic tubes bending or
The inclination of whole device is unstable, and therefore the present invention also provides for a kind of embodiment, as shown in Figure 6, at described three grades of telescopics
Pipe 3 is internal fixes a slideway 16, loads onto pulley assembly 17 and arrange stopping means 19 at two ends inside described slideway 16, will
Certain joint of pulley assembly 17 and secondary transmission chain 13 or more piece are fixed, when stopping means 18 is not touched with pulley gear 18,
Secondary transmission chain 13 band movable pulley device 7 does linear slide in slideway 16, and when the stopping means 18 of front end, to encounter pulley total
When becoming 17, the rotation of secondary transmission chain 13 makes pulley assembly 17 drive the stopping means 18 of front end to move forward, thus carries
Forward extending out of dynamic three grades of telescopic tubes 3, with should the stopping means 18 of rear end encounter pulley assembly 17 time, it is achieved three grades are stretched
Being inwardly indented of sleeve pipe 3, the most just can realize the inequality stretching motion of three grades of telescopic tubes 3.
In order to reduce two grades of telescopic tubes 2 and three grades of telescopic tubes 3 at flexible force of sliding friction, therefore at described two grades
The first roller 19 contacted with one-level telescopic tube 1 it is provided with on telescopic tube 2, and on described three grades of telescopic tubes 3
It is arranged at the second roller 20 that two grades of telescopic tubes 2 contact so that sliding friction is converted into rolling friction, stretches in raising
Under smoothness, reduce the abrasion for sleeve pipe, extend the service life of device.
In addition to the implementation, present invention additionally comprises other embodiments, all employing equivalents or equivalence to replace
The technical scheme that mode is formed, all should fall within the scope of the hereto appended claims.
