Description
Technical field
The utility model relates to the interconnective telescopic system of a kind of bar or pipe and locks in the neutral position, but the pipe that particularly a kind of stepless retractable is regulated.
Technical background
The pipe of scalable adjusting comprises bassoon in the technology now, tubule and controlling device, tubule is enclosed within the bassoon, when needing to regulate, bassoon and tubule move into place the back mutually and fix by controlling device, this controlling device mostly is a kind ofly radially to be fixed on screw in the bassoon along bassoon, in the time of need carrying out telescopic adjustment, screw is unscrewed, bassoon and tubule just can relatively move, and again with screw-driving, perhaps this controlling device is a kind of latch after moving into place, on bassoon and tubule, have along caliber to the hole, during adjusting, make the hole correspondence on bassoon and the tubule, then latch is inserted.Owing to need come the operating regulation device with a hand when regulating with such controlling device, the another hand is used for moving pipe, the telescopic adjustment complicated operation, and it is very inconvenient to use, and also requires great effort very much.
Summary of the invention
It is a kind of easy to operate that technical problem to be solved in the utility model is to provide, but the pipe that uses the labour-saving stepless retractable to regulate.
The utility model is realized by following approach.
But the pipe that stepless retractable is regulated, comprise bassoon, tubule and controlling device, tubule is enclosed within the bassoon, its structure outline is: controlling device comprises mandrel, cone and a plurality of rolling element, cone axially is installed on the mandrel along mandrel, and the tube wall of tubule along the circumferential direction is distributed with plurality of holes, rolling element is positioned at this hole, and between the tube wall and cone of bassoon.
Like this, moving cone by mandrel just can make rolling element be positioned at the small end of cone, thereby bassoon and tubule can be relatively moved, mandrel moves and can make rolling element be positioned at the big end of cone, and rolling element is squeezed between the tube wall of cone and bassoon and fixes, because rolling element is installed in the hole on the little tube wall, so bassoon and tubule relative fixed.But the pipe of scalable adjusting so not only has the function that stepless retractable is regulated, can so that bassoon and tubule relative fixed in any position, and it is simple to operate, only need catch the mobile then mandrel of tubule with hand, it is the position between can regulate bassoon and the tubule, and then mobile mandrel makes, and bassoon and tubule are fixing to get final product, easy to use, laborsaving, and it is simple in structure, can be widely used in the various devices that need telescopic adjustment, as medical apparatus, sports apparatus, furniture, multilayer airing support, camera mount, microphone holder etc.
Because mandrel is axially being installed in the tubule along tubule, therefore, mandrel stretches out and exposes to outside the tubule from the end of tubule, just can move when needing mobile mandrel by the exposed junction of mandrel, and, at the end that mandrel exposes one pressure cap is installed, thereby is convenient to push or draws and dial mobile mandrel.
Structure of the present utility model can be specially.
Because but the pipe that stepless retractable is regulated bears different active forces in different device, sometimes for bearing the garter frame in pressure such as the medical apparatus, sometimes for to bear pulling force as being suspended to the device that needs telescopic adjustment on the ceiling board, therefore, but the pipe that in different devices, uses different stepless retractables to regulate.
When bearing pressure, needs do the time spent:
The small end of cone is towards a side of tubule and bassoon socket end.
Like this, when the time spent of doing that tubule bears pressure, rolling element is crowded more tight more between the tube wall of cone and bassoon, and what bassoon and tubule can be firm is fixing.
When needs bear tension:
The big end of cone is towards a side of tubule and bassoon socket end.
Like this, when the time spent of doing that tubule bears pulling force, rolling element is also crowded more tight more between the tube wall of cone and bassoon, and what bassoon and tubule can be firm is fixing.
Rolling element described in the utility model is a kind of spheroid.
Can make like this in the hole of rolling element on little tube wall roll more smooth and easy.
Structure of the present utility model can further be specially:
Since mandrel be along tubule the axle be installed in the tubule, for ease of mobile mandrel, therefore, controlling device also comprises:
Controlling device also comprises controlling rod, has a symmetrical groove on the tube wall of tubule, and controlling rod passes groove and is connected with intratubular mandrel, and its two ends expose to the outside of tubule.
Controlling device also comprises the control axle sleeve, and the Control Shaft cover is enclosed within the outside of tubule, and the exposed junction of controlling rod is fixed in Control Shaft and puts.
Like this, when regulating the position of tubule, catch tubule with hand, pass the control axle sleeve with thumb, the control axle sleeve drives mandrel by controlling rod and moves, thus with a hand just can be easy and convenient operate.
Controlling device also comprises a spring, and spring is axially installed along body, and the one end leans the end face at the big end of cone, and the other end leans on tubule.
Like this, when tubule is adjusted to the desired position, only need open openhanded, spring will automatic mobile cone, make the big end squeezing roll of cone kinetoplast, thereby bassoon and tubule relative fixed is used just convenient.
Quantity for rolling element should be two at least, perhaps also can be 3, perhaps also can be 4, and is perhaps more, and the quantity of this rolling element is determined according to caliber size and the active force that is born.
In sum, the utility model has the following advantages compared to existing technology: cone and rolling element are installed in body, the feature that does not wait by cone diameter, rolling element is fixed and unclamped, and the active force by spring makes the cone fixedly rolling element that can automatically reset, thereby carry out telescopic adjustment easily, simple to operate, only need a hand just can finish, easy to use, laborsaving, simple in structure.
