Description
Technical field
It is especially suitable for common temporary support, semipermanent or permanent support the present invention relates to a kind of telescopic supporting rod
Quick support for rescue and relief work field.
Background technology
In daily life, especially often use and weight is propped up in industrial installing area or rescue and relief work field
The support bar of support is supported reinforcing to object, is divided according to support bar usage time, is generally divided into three kinds：1. interim branch
Support, support finish the temporary support bar removed at once；2. being reinforced after support, have detachable the half of certain service life
Permanent support bar；3. reinforced after support, the permanent support bar do not removed.
At present, conventional support bar is usually rod or metallic rod, and the bearing capacity of rod is smaller, is typically used as provisional
Support bar, metallic rod weight are larger；No matter rod or metallic rod it is typically non-retractable, it is impossible to pass through the length of the flexible body of rod
Spend to adapt to the height of supported objects, ordinary circumstance, only adapt to be supported by intercepting the length of rod or metallic rod
The height of object, it is therefore, cumbersome in real work；Also have at present and be supported using jack, very heavy during use
It is supported on top plus the superposition of one or more supporting objects.If be supported from a supporter on jack,
So the height of this supporter must be mutually suitable with by bearing height, and ordinary circumstance can only intercept the length of supporter, this
Method is more time-consuming；It is supported if be superimposed upon from multiple supporting objects on jack, in actual production or speedily carries out rescue work
Potential safety hazard is left in the disaster relief, to sum up, the method for supporting of problem of the prior art can not be implemented fast and effectively, especially rob
During the dangerous disaster relief, this technological deficiency is more prominent.
The content of the invention
The present invention goal of the invention be:To overcome support of the prior art without the energy supporting heavy for having light quick-expansion
Bar, it is an object of the invention to provide the support bar of the energy supporting heavy of light quick-expansion, can be used for common interim branch
Support, semipermanent or permanent support are can be used for, the height of supported objects is adapted to by the length for the body of rod that stretches, reached
To quick support, supporting ＆ stablizing, the purpose that safe, weight capacity is strong, simple to operate.
The present invention is achieved through the following technical solutions：
A kind of telescopic supporting rod, including overcoat tube body, inner sleeve tube body；
Described outer tube body interior is provided with inner sleeve tube body；
There is overcoat tube chamber in described overcoat tube body；

More than the two sections inner circle arcs that the inner horizontal direction that described internal tooth form protrusion includes overcoat tube chamber is set
" internal tooth "；
The uniform parallel external tooth form that is distributed with of the outside entire body of described inner sleeve tube body protrudes 2-1；
Described external tooth form protrusion 2-1 includes more than horizontally arranged two section of inner sleeve body exterior cylindrical arcs
" external tooth "；
The tooth form phase interworking of the internal tooth form protrusion of described overcoat tube body and the external tooth form protrusion 2-1 of inner sleeve tube body
Close.
A kind of more preferred telescopic supporting rod, the epimere of described outer tube inside cavity have uniform parallel distribution
Internal tooth form is protruded, and the bottom of internal tooth form protrusion is hollow straight tube, or described outer tube inside cavity entire body is uniform parallel point
It is furnished with internal tooth form protrusion.
A kind of more preferred telescopic supporting rod, there is locating slot in the middle part of described " external tooth "；Described overcoat tube body
Also include safe catching lock, safe catching lock is arranged on the side of the epimere of overcoat tube body；Described safe catching lock also includes positioning
Thimble, elastomer, the elastomer of the inside of safe catching lock overlap the inside bullet of thimble, internal tooth form protrusion and external tooth form protrusion rotation
When, thimble is caught in locating slot；Further, described safe catching lock is substituted using only tight screw.
A kind of more preferred telescopic supporting rod, described internal tooth form protrude the inner horizontal direction for including overcoat tube chamber
Two sections be oppositely arranged are less than " internal tooth " of the circular arc of 1/4 inner circle arc length；Described external tooth form protrusion 2-1 includes inner sleeve sheet
Both sides outside body, two sections of " external tooths " for being less than 1/4 cylindrical arc length that horizontal direction is oppositely arranged；Described internal tooth form protrusion
The both ends of the circular arc of tooth and the angle a in the center of circle are less than 90 °, the angle b between the tooth of adjacent two internal tooth forms protrusions and the center of circle
More than 90 °；The both ends of circular arc of described external tooth form protrusion 2-1 tooth and the angle d in the center of circle are less than 90 °, and adjacent two outer
Angle c between tooth form protrusion 2-1 tooth and the center of circle is more than 90 °；
More preferred described angle a is 85 ° to 89.5 °, and angle b is 90.5 ° to 95 °, angle c be 90.5 ° extremely
95 °, angle d is 85 ° to 89.5 °.
A kind of more preferred telescopic supporting rod, described angle a are 89 °, and angle b is 91 °, and angle c is 91 °, angle d
It is 89 °.
A kind of more preferred telescopic supporting rod, described elastomer are spring, plastic elastomeric or flexure strip.
The advantageous effects that the present invention obtains are：Support bar adapts to the height of supported objects by quick-expansion,
Installation rate is fast；Common laborer directly can skilled installation operation, the weight capacity of support bar is big, realizes common temporary support,
Semipermanent or permanent support are can be used for, reaches quick support, supporting ＆ stablizing, safe, weight capacity is strong, operation
Simple purpose is especially especially prominent in the situation higher to speed and safety requirements such as rescue and relief work, advantage.
