Abstract
A telescopic sleeve comprises four sleeve arc-shaped plates, supporting connecting rods, a cylindrical thread connecting rod, U-type connecting plates and round connecting plates. The supporting connecting rods comprise four upper supporting rods and four lower supporting rods, wherein the upper supporting rods and the four lower supporting rods are arranged symmetrically. The sleeve arc-shaped plates comprise the inner sleeve arc-shaped plates and the outer sleeve arc-shaped plates, wherein the inner sleeve arc-shaped plates and the outer sleeve arc-shaped plates are overlapped to form a complete round closed sleeve. The concave bottom faces of the U-type connecting plates are fixedly installed on the inner walls of the sleeve arc-shaped plates through screws. Each sleeve arc-shaped plate is movably connected with one upper supporting rod and one lower supporting rod through the corresponding U-type connecting plate at the same time. The cylindrical thread connecting rod sequentially penetrates through screw holes in the upper round connecting plate and the lower round connecting plate. In a using state, through rotating the cylindrical thread connecting rod in forward and backward directions, the included angle alpha between the upper supporting rods and the lower supporting rods is changed, so that the diameter D of the telescopic sleeve formed by the four sleeve arc-shaped plates is changed. The telescopic sleeve is simple in structure, convenient to construct and capable of being used repeatedly.

Under using state, change the size of angle α between upper and lower support bar by forward and reverse turn cylindrical thread connecting rod thus change the size of telescopic sleeve pipe diameter D formed by 4 pieces of sleeve pipe arcs.
Its further technical scheme is: the shape of cross section of described supporting linkage is rectangle, circle or oval.
Further: the top of described cylindrical thread connecting rod is hexagon, and bottom is sharp arachnoid.
The top of described cylindrical thread connecting rod is provided with suspension ring or lifting hole(eyelet).
Again further: described sleeve pipe arc is made up of aluminum alloy materials.
Compared with prior art, the present invention's it " telescopic sleeve pipe " has following beneficial effect:
1, telescopic sleeve pipe structure of the present invention is simple, reasonable in design, easy construction:
Telescopic sleeve pipe of the present invention adopts internal and external casing arc to be connected with symmetrically arranged upper support bar 11, lower support 12 by U-shaped junction plate, form complete round sealed sleeve pipe, in a state of use, change the size of angle α between upper and lower support bar by forward and reverse turn cylindrical thread connecting rod 5 thus change the size of telescopic sleeve pipe diameter D formed by 4 pieces of sleeve pipe arcs 2, reasonable in design, each link structure is simple and easy to processing; Realize the unification of original various different sleeve pipe caliber, the service sleeve regardless of which kind of caliber all can adopt telescopic tube to replace;
Secondly, cylindrical thread connecting rod bottom design is sharp arachnoid, and sleeve pipe can be made to be fixed on the building space of a whole page, and top is that hexagon is convenient to rotate, and rotating forward can make sleeve pipe expand, and reversion can make sleeve pipe reduce, and uses simple; The installation of civil engineering floor masterplate, locates by design drawing, and rotate forward screw rod and expand suitable diameter to, sleeve pipe can be fixed on floor face, settles at one go, easy construction.
2, telescopic sleeve pipe energy-conserving and environment-protective of the present invention, can repeatedly reuse.The present invention's aluminium alloys does the material of telescopic sleeve pipe, indeformable, not easily aging, reusable, energy-conserving and environment-protective.
3, good economic benefits is had.Telescopic sleeve pipe not only material is cheap, and can effectively raise operating efficiency, shortens the duration, reduces construction costs, thus obtain obvious economic benefit.
Be described further below in conjunction with the technical characteristic of drawings and Examples to the telescopic sleeve pipe of the present invention.
