Description
The present invention is a kind of divisional application of patent of invention " supporting rod of the supporting heavy of quick-expansion ", the Shen of original application
It please be on May 30th, 2016 day, the application number of original application is 2016103618842, and the invention and created name of original application is " a kind of
The supporting rod of the supporting heavy of quick-expansion ".
Technical field
The present invention relates to a kind of telescopic supporting rods, especially suitable for common temporary support, semipermanent or permanent support
For the quick support in rescue and relief work field.
Background technology
In daily life, it especially often uses and weight is propped up in industrial installing area or rescue and relief work field
The supporting rod of support is supported object reinforcing, is divided according to supporting rod 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 supporting rod；3. it is reinforced after support, the permanent supporting rod do not removed.
At present, common supporting rod is usually rod or metallic rod, and the bearing capacity of rod is smaller, is typically used as provisional
Supporting rod, 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
The height to adapt to supported objects is spent, ordinary circumstance only adapts 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 one or more supporting object superpositions.If a supporter is selected to be supported on jack,
So the height of this supporter must be supported height it is mutually suitable, ordinary circumstance can only intercept the length of supporter, this
Method is more time-consuming；It is supported if multiple supporting objects is selected to be superimposed upon on jack, in actual production or speedily carries out rescue work
Security risk is left in the disaster relief, to sum up, the method for supporting of problem of the prior art cannot be implemented quickly and effectively, especially rob
During the dangerous disaster relief, this technological deficiency is more prominent.
Invention content
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, the purpose of the present invention is to provide the supporting rods of the energy supporting heavy of light quick-expansion, can be used for common interim branch
Support can be used for semipermanent or permanent support, adapt to the height of supported objects by the length for the body of rod that stretches, reach
To quick support, supporting ＆ stablizing, the purpose that safe, load-bearing capacity is strong, easy to operate.
The present invention is achieved through the following technical solutions：
A kind of telescopic supporting rod, including housing tube body, inner sleeve tube body；

The internal tooth form protrusion includes the " interior of two sections or more inner circle arcs of the inner horizontal direction setting of housing tube chamber
Tooth "；
The uniform parallel distribution of external entire body of the inner sleeve tube body has external tooth form to protrude 2-1；
The external tooth form protrusion 2-1 includes horizontally arranged two section of inner sleeve body exterior or more outer circle arc
" external tooth "；
The tooth form of the internal tooth form protrusion of the housing tube body and the external tooth form protrusion 2-1 of inner sleeve tube body cooperate.
A kind of more preferred telescopic supporting rod, the epimere of the outer tube inside cavity have uniform parallel distribution
Internal tooth form is protruded, and the lower part of internal tooth form protrusion is hollow straight tube or the outer tube inside cavity entire body is parallel point uniform
It is furnished with internal tooth form protrusion.
A kind of more preferred telescopic supporting rod has locating slot in the middle part of " external tooth "；The housing tube body
Safe catching lock is further included, safe catching lock is mounted on the side of the epimere of housing tube body；The safe catching lock further 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, the safe catching lock is substituted using only tight screw.
A kind of more preferred telescopic supporting rod, the internal tooth form protrude the inner horizontal direction for including housing tube chamber
Two sections be oppositely arranged are less than arc-shaped " internal tooth " of 1/4 inner circle arc length；The 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 outer circle arc length that horizontal direction is oppositely arranged；The 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 the tooth of the external tooth form protrusion 2-1 and the angle d in the center of circle are less than 90 °, and adjacent two outer
Angle c between the tooth of tooth form protrusion 2-1 and the center of circle is more than 90 °；
The more preferred angle a is 85 ° to 89.5 °, and angle b is 90.5 ° to 95 °, and angle c is 90.5 ° to 95 °, folder
Angle d is 85 ° to 89.5 °.
A kind of more preferred telescopic supporting rod, the 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, the elastomer are spring, plastic elastomeric or elastic piece.
The advantageous effects that the present invention obtains are：Supporting rod adapts to the height of supported objects by quick-expansion,
Installation speed is fast；Common laborer directly can skilled installation operation, the load-bearing capacity of supporting rod is big, realizes common temporary support,
Semipermanent or permanent support are can be used for, reaches quick support, supporting ＆ stablizing, safe, load-bearing capacity is strong, operation
Simple purpose, especially in the situation higher to speed and safety requirements such as rescue and relief work, advantage especially protrudes.
