Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
Referring to shown in Fig. 1 Fig. 5, the single former multi-stage mechanical of one of the present embodiment is driven stretching structure, including covering successively
1, two grades of telescopic tubes 2 of the one-level telescopic tube connecing and three-level telescopic tube 3, described one-level telescopic tube 1 two ends are fixed on one
On axle bed 5 after axle bed 4 and one-level before level, before after axle bed 4 and one-level before described one-level, the bottom of axle bed 5 is respectively arranged with one-level
Sprocket wheel 7 after sprocket wheel 6 and one-level, sprocket wheel 7 after sprocket wheel 6 and one-level before described one-level is provided with primary transmission chain 8, and described one
Level driving chain 8 is located at the lower inside of one-level telescopic tube 1, and wherein before one-level, sprocket wheel 6 is as motive power wheel and outside electricity
Machine is connected, and is rotated by thus driving primary transmission chain 8 to rotate, in the upper half of described one-level transmission chain 8 in motor
Part has one section of breach, and this breach passes through the first connecting plate 9 and is connected, after described first connecting plate 9 and two grades of telescopic tubes 2
End is fixedly connected, and when primary transmission chain straight forward movement under motor drive, drives two grades of telescopic tubes 2 to be stretched by one-level
Heat-Shrinkable Tubings 2 are internal protruding, thus realize two grades stretching；
Sprocket wheel 11 after sprocket wheel 10 and two grades before the inside front and back end of described two grades of telescopic tubes 2 is provided with two grades, in institute
It is provided with secondary transmission chain 13 on sprocket wheel 11, chain after sprocket wheel 10 and two grades before described two grades after sprocket wheel 10 and two grades before stating two grades
The low portion of wheel 11 is exposed to the bottom of two grades of telescopic tubes 2 so that the latter half of secondary transmission chain 13 is stretched positioned at two grades
The outside of Heat-Shrinkable Tubings 2, has another breach in the latter half of described secondary transmission chain 13, and this breach passes through the second connecting plate
14 connections, described second connecting plate 14 is fixed with the bottom of one-level telescopic tube 1 through after the notch of two grades of telescopic tube 2 bottoms
Connect, when two grades of telescopic tube straight forward movement of primary transmission chain-driving, the second grade transmission chain in two grades of telescopic tubes
Bar should also be as travelling forward in theory, but because the second connecting plate is fixedly connected with one-level telescopic tube, now, secondary transmission
The straight forward movement of chain is converted into rotation, and the top half of described secondary transmission chain 13 pass through the 3rd connecting plate 15 with
The rear end of three-level telescopic tube 3 is fixedly connected, and therefore realizes the three of three-level telescopic tube 3 under the rotation of secondary transmission chain 13
Level is flexible.By that analogy, by the setting of said structure, it is possible to achieve level Four, Pyatyi or more stages flexible, and only need to
Realize under the driving of a power source motor.
Such scheme is accomplished that sleeve pipe trackless equivalent stretching motions at different levels, and that is, two grades of telescopic tubes 2 stretch out how many distances,
Secondary transmission chain 13 also stretches out how many distances so that three-level telescopic tube 3 equivalent stretches out identical distance, in some situations
Under, the excessive load that it carries of distance that three-level telescopic tube stretches out just reduces, be easily caused three-level telescopic tube bending or
The inclination of whole device is unstable, and therefore this utility model also provides a kind of embodiment, as shown in fig. 6, stretching in described three-level
Fix a slideway 16 inside Heat-Shrinkable Tubings 3, load onto pulley assembly 17 inside described slideway 16 and stopping means are set at two ends
18, pulley assembly 17 is fixed with certain section of secondary transmission chain 13 or more piece, when stopping means 18 are not touched with pulley assembly 17
When touching, secondary transmission chain 13 drives pulley assembly 17 to do linear slide in slideway 16, when the stopping means 18 of front end are encountered
During pulley assembly 17, the rotation of secondary transmission chain 13 makes pulley assembly 17 drive the stopping means 18 of front end to move forward,
Thus driving forward extending out of three-level telescopic tube 3, with should the stopping means 18 of rear end encounter pulley assembly 17 when, realize three
Being inwardly indented of level telescopic tube 3, so just can realize the inequality stretching motion of three-level telescopic tube 3.
In order to reduce two grades of telescopic tubes 2 and three-level telescopic tube 3 in flexible force of sliding friction, therefore at described two grades
The first roller 19 being contacted with one-level telescopic tube 1 is provided with telescopic tube 2, and on described three-level telescopic tube 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, flexible improving
Under smoothness, reduce the abrasion for sleeve pipe, extend the service life of device.
In addition to the implementation, this utility model also includes other embodiment, all employing equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within this utility model scope of the claims.
