Description

A kind of telescopic supporting rod of the semipermanent supporting heavy of fast self-locking
The present invention is a kind of divisional application of patent of invention " support bar of quick-expansion supporting heavy ", the application of original application Day is on May 30th, 2016, and the application number of original application is 2016103618838, and the invention and created name of original application is " a kind of fast The support bar of the flexible supporting heavy of speed ".
Technical field
The present invention relates to a kind of quick-expansion support bar, supports for common temporary support, semipermanent or permanently, especially It is applied to 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 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 quick-expansion support bar, including overcoat tube body, inner sleeve Tube body, described outer tube body interior are provided with inner sleeve tube body；There is overcoat tube chamber in described overcoat tube body；Institute The outer tube inside cavity stated has internal tooth form protrusion；Described internal tooth form protrusion includes the inner horizontal direction phase of overcoat tube chamber To " internal tooth " of three sections of circular arc for being less than 1/6 inner circle arc length of setting；The outside entire body of described inner sleeve tube body is uniform It is parallel that external tooth form protrusion is distributed with；Described external tooth form protrusion includes three sections that inner sleeve body exterior horizontal direction is uniformly arranged Less than " external tooth " of 1/6 cylindrical arc length；Further, the both ends of circular arc of the tooth of described internal tooth form protrusion and the angle in the center of circle A is less than 60 °, and the angle b between the tooth of adjacent two internal tooth forms protrusion and the center of circle is more than 60 °；Further, described external tooth The both ends of the circular arc of the tooth of shape protrusion and the angle d in the center of circle are less than 60 °, between the tooth of adjacent two external tooth forms protrusion and the center of circle Angle c be more than 60 °；Further, described angle a is 55 ° to 59.5 °, and angle b is 60.5 ° to 65 °, and angle c is 60.5 ° to 65 °, angle d is 55 ° to 59.5 °；Further, the internal tooth form protrusion and inner sleeve sheet of described overcoat tube body The tooth form of the external tooth form protrusion of body cooperates.
A kind of more preferred quick-expansion support bar, the epimere of described outer tube inside cavity have uniformly parallel point The internal tooth form protrusion of cloth, the bottom of internal tooth form protrusion is hollow straight tube, or described outer tube inside cavity entire body is uniformly put down Internal tooth form protrusion is distributed with row.
A kind of more preferred quick-expansion support bar, there is locating slot in the middle part of described " external tooth "；Described outer tube Body also includes safe catching lock, and 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 rotate the inside bullet of thimble, internal tooth form protrusion and external tooth form protrusion During coincidence, thimble is caught in locating slot.
A kind of more preferred quick-expansion support bar, described elastomer are spring, plastic elastomeric or flexure strip；Enter One step, described safe catching lock is substituted using only tight screw.
A kind of more preferred quick-expansion support bar, described angle a are 59 °, and angle b is 61 °, and angle c is 61 °, Angle d is 59 °.
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.
