Description
Technical field
The invention belongs to telescoping tube technical field, especially relate to a kind of inner locking type and stretch aluminum
Pipe.
Background technology
Telescoping tube its there is Telescopic, such as may be used for including swimming pool cleaning tool etc.
Deng on equipment, it can extend in use, when not in use, can shrink, not only
Can meet and use requirement, and spatial area can also be saved, it is simple to carry and collect, stretch
The structure of the draw is generally mutually to be socketed by many knots pipe and combines, and stretches to be able to improve
The connective stability of axial restraint between each knot pipe when the draw uses, to this end, people enter
Go long-term exploration, it is proposed that various solutions.
Such as, Chinese patent literature disclose a kind of telescoping tube [application number:
200920205587.4], including outer tube, and outer in-pipe movable with outer tube can be stretched into
The inner tube connected, at least provided with two and above hole, described inner tube on described outer tube
On at least provided with one and above hole, in inner tube, be provided with a locking device, described lock
Determine device and include an elastic sheet metal bent, and be located at outside elastic sheet metal one end
Column on surface, described column diameter is less than the hole of institute's apertured on outer tube and inner tube
Footpath, when inner tube is connected with outer tube, inner tube accommodates locking device position and is positioned at outer tube,
And the most described column free end through the hole in inner tube and outer tube and is positioned at outside outer tube
Portion.
Above-mentioned scheme has a simple in construction, easy accessibility, low cost and also easy to use
Advantage；But the most at least there is following defect in the program: designs unreasonable, outer tube with
Between inner tube, its axial restraint intensity is low and inner tube the phenomenon that moves axially easily occurs, separately
Outward, structure is complicated and the axial locking of wayward inner tube or cancel axial locking, secondly,
After locking, its inner tube is the most concentric with outer tube, poor practicability.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of easy to control, axial lock
Only firm and the most practical inner locking type stretches aluminum pipe.
For reaching above-mentioned purpose, present invention employs following technical proposal: this inner locking type is stretched
Contracting aluminum pipe includes telescopic tube, and this telescopic tube includes that outer tube and one end wear within the outer tube
And the inner tube that can move axially along outer tube, set in one end mouth of pipe in inner tube inserts in outer tube
Have and be connected and the positioning sleeve of axial restraint with outer tube circumference, positioning sleeve is provided with outside inserting in
Its fagging, inner tube in the rotation that outer tube rotates can be driven in pipe and when rotating inner tube
Axial line overlaps settings with rotating internal stay plate axial line, be arranged with on fagging in rotation and
Inner tube bias be connected and when in rotating, fagging rotates can respectively with the both sides of fagging in rotation
Contact thus radially outward deform upon make described inner tube relative to outer tube axial restraint, with
And make interior tube axis line and the deformation locking mechanism of outer tube axial line coincidence simultaneously.
In this application, it is provided with deformation locking mechanism and can make the axial locking of inner tube or cancellation
The axial locking of inner tube is convenient and simple, is difficult to axle after can guarantee that the axial locking of inner tube
To movement, it is not only simple in structure, and is easily manipulated, it addition, this deformation locking mechanism
After can guarantee that the axial locking of inner tube, its axial line overlaps with the axial line of outer tube, makes junction
Uniform force, is further ensured that intensity and the service life of structure, and locking intensity is high and real
Strong by property.
When the flexible aluminum pipe of the application needs to elongate or shorten, rotate inner tube and drive location
Set rotates, and in positioning sleeve rotates thus drives the rotation being located on positioning sleeve, fagging rotates,
In rotating, fagging rotates and makes deformation locking mechanism make radially outward to deform upon, and deformation is locked
Inner tube can be realized when contacting when structure is not with outer tube wall and move axially (realization along outer tube
Flexible purpose)；When elongation or flexible after flexible aluminum pipe length reach use require time,
Rotating inner tube drives positioning sleeve to rotate, and positioning sleeve rotates thus drives and be located on positioning sleeve
In rotating, fagging makes deformation locking mechanism radially outward deform upon, when deformation locking mechanism
Inner tube can be realized when contacting with outer tube wall and (realize the most solid relative to outer tube axial restraint
Fixed purpose), the axial line of inner tube and the axle of outer tube when inner tube is relative to outer tube axial restraint
Heart line overlaps, and makes junction uniform force, uses bilateral to lock the connection at not only locking
Intensity is high, and service life is long.
Stretching in aluminum pipe at above-mentioned inner locking type, described deformation locking mechanism includes inwall

Tong Bu radially outward deformation is there is, semicircular body two in described first with the second outer arc body
In end and second, semicircular body two ends are mutually butted the formation tubular structure that is connected as a single entity；Or institute
In first stated, in semicircular body and second, semicircular body split is arranged.When rotating internal stay
During plate, the structure energy that in first, in semicircular body two ends and second, semicircular body two ends are mutually butted
Abut, the two ends phase interaction of semicircular body in the two ends of semicircular body and second in i.e. first
With, it is further ensured that the axial locking of inner tube or cancels the stablizing of manipulation of the axial locking of inner tube
Property.
In the first of the application, the axial line of semicircular body is misaligned with outer tube axial line, and second
The axial line of interior semicircular body is misaligned with outer tube axial line, it addition, this semicircular body in first
The gross thickness superimposed with the first outer arc body is equal to semicircular body and the second outer arcuate in second
The gross thickness that body is superimposed, secondly, the effect being positioned at the structure on same circumference is to work as
Make interior tube axis line overlap with outer tube axial line after the axial locking of inner tube, make junction circumference
Uniform force；Elastomeric material includes any one in rubber and silica gel.Certainly, as long as
Can meet and use requirement, other materials can also use, and secondly, elastomeric material can also increase
Large access area.
