Description
The present invention is a kind of divisional application of patent of invention " quick telescopic supporting rod ", and the applying date of original application is 2016
In on May 30, in, the application number of original application is 2016103618221, and the invention and created name of original application is " a kind of quickly flexible
Supporting rod ".
Technical field
The present invention relates to a kind of quick telescopic supporting rod, supports for common temporary support, semipermanent or permanently,
It is particularly suitable for the quick support in 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 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. 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
Spend to adapt to the height of supported objects, 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 selecting a supporter 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 selecting multiple supporting objects 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 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 supporting rod 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, adapts 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 quick telescopic supporting rod, including overcoat tube body, inner sleeve tube body, the outer tube body interior are provided with
Inner sleeve tube body；There is overcoat tube chamber in the overcoat tube body；The outer tube inside cavity has internal tooth form protrusion；Institute
The internal tooth form protrusion stated includes four sections of circular arcs for being less than 1/8 inner circle arc length that the inner horizontal direction of overcoat tube chamber is uniformly arranged
" internal tooth " of shape；The uniform parallel distribution of exterior entire body of the inner sleeve tube body has external tooth form protrusion；The external tooth form
Protrusion includes four sections of " external tooths " for being less than 1/8 cylindrical arc length that inner sleeve body exterior horizontal direction is uniformly arranged；Further,
The both ends of circular arc of the tooth of the internal tooth form protrusion and the angle a in the center of circle are less than 45 °, the tooth of adjacent two internal tooth form protrusions
Angle b between the center of circle is more than 45 °；Further, the both ends of circular arc of the tooth of external tooth form protrusion and the folder in the center of circle
Angle d is less than 45 °, and the angle c between the tooth of adjacent two external tooth forms protrusion and the center of circle is more than 45 °；Further, the folder
Angle a is 40 ° to 44.5 °, and angle b is 45.5 ° to 50 °, and angle c is 45.5 ° to 50 °, and angle d is 40 ° to 44.5 °；Further
, the tooth form that the internal tooth form protrusion of overcoat tube body and the external tooth form of inner sleeve tube body protrudes cooperates.
A kind of more preferred quick telescopic supporting rod, the epimere of the outer tube inside cavity have uniform parallel
The internal tooth form protrusion of distribution, the lower part of internal tooth form protrusion is hollow straight tube, or the outer tube inside cavity entire body is uniform
Parallel distribution has internal tooth form protrusion.
A kind of more preferred quick telescopic supporting rod, has locating slot in the middle part of " external tooth "；The overcoat
Tube body further includes safe catching lock, and safe catching lock is installed on the side of the epimere of overcoat tube body；The safe catching lock also wraps
Positioning thimble, elastomer are included, the elastomer of the inside of safe catching lock revolves the inside bullet of thimble, internal tooth form protrusion and external tooth form protrusion
When turning to overlap, thimble is caught in locating slot.
A kind of more preferred quick telescopic supporting rod, the elastomer are spring, plastic elastomeric or elastic piece,
Further, the safe catching lock is substituted using only tight screw.
A kind of more preferred quick telescopic supporting rod, the angle a is 44 °, and angle b is 46 °, and angle c is
46 °, angle d is 44 °.
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 is especially especially prominent in the situation higher to speed and safety requirements such as rescue and relief work, advantage.
