Including interior side pipe and the foreign side pipe of inserting together, connect base and pedal structure as an organic whole, a serial communication port, the cross sectional shape of interior side pipe is the rectangle structure of taking the fillet, the upper end of interior side pipe has spacing boss and contact boss, the cross sectional shape of outer side pipe is the rectangle structure of taking the fillet, its lower tip has the spacing boss of foreign side pipe boss and interior side pipe to form the cooperation relation, connect base boss and upper and lower pin blind hole, insert in the foreign side pipe and connect the base, through structure glue and last pin, lower pin is connected with the connection base, outer side pipe and interior side pipe adopt carbon fiber or glass fiber prepreg to make, connect the base, pedal and pin adopt metal material to make. The utility model discloses light in weight, rigidity are big, multisection cooperation precision is high, can effectively guarantee overall structure's stability.
Description
Technical Field
The utility model relates to a telescopic ladder field says in detail to a combined material side's pipe extending structure.
Background
As is well known, the composite material square tube telescopic structure is widely used by telescopic ladders due to its advantages of light weight, high rigidity, small volume, etc. However, the matching of the composite square tubes is difficult, and the multiple sections have poor matching stability and are easy to draw and clamp.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a composite material square tube telescopic structure, light in weight, rigidity are big, multisection cooperation precision is high.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a combined material side's pipe extending structure, including interior side's pipe and the outer square pipe of inserting together, connect base and pedal structure as an organic whole, a serial communication port, the cross sectional shape of interior side's pipe is the rectangle structure of taking the fillet, the upper end of interior side's pipe has spacing boss and contact boss, the cross sectional shape of outer side's pipe is the rectangle structure of taking the fillet, its lower tip has the spacing boss of outer square pipe boss and interior side's pipe to form the cooperation relation, connect base and have base boss and upper and lower pin blind hole, insert the connection base in the outer square pipe, through structure glue and last pin, lower pin is connected with the connection base, outer side's pipe and interior side's pipe adopt carbon fiber or glass fiber prepreg to make, connect the base, pedal and pin adopt metal material to make.
The beneficial effects of the utility model are that, light in weight, rigidity are big, multisection cooperation precision is high, can effectively guarantee overall structure's stability.
Drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1-an inner square tube, 2-a limiting boss, 3-a contact boss, 4-an upper pin, 5-a lower pin, 6-a connecting base, 7-a base boss, 8-a pedal, 9-an outer square tube and 10-an outer square tube boss.
Detailed Description
In the figure, the utility model discloses be equipped with the utility model discloses by interior side pipe 1, connect base 6, pedal 8 and outer side pipe 9 and constitute, connect base 6 and pedal 8 and be metal integrated into one piece, the material uses the aluminum alloy to be suitable. The outer square pipe 9 and the outer square pipe boss 10 at the lower end part of the outer square pipe are integrally formed by adopting carbon fiber or glass fiber prepreg through a die pressing process of a built-in core die, the cross section of the outer square pipe 9 is in a rectangular structure with round corners, and the outer square pipe is convenient to machine and form and high in efficiency. During the assembly at first with the outer square pipe 9 interpolation connect the base 6, adopt the structure to glue and go up pin 4 and pin 5 will connect base 6 and outer square pipe 9 together down, go up pin 4 and pin 5 material selection for use stainless steel or titanium alloy down and be suitable. The thickness of the boss 10 of the outer square pipe on the outer square pipe 9 is not larger than that of the boss 7 of the base on the connecting base 6, and the thicknesses of the boss and the boss are preferably the same. Interior square pipe 1 and its upper end's spacing boss 2 and contact boss 3 adopt carbon fiber or glass fiber preimpregnation material to pass through the mould pressing technology integrated into one piece of built-in mandrel, interior square pipe 1 cross sectional shape is the rectangle structure of taking the fillet, machine-shaping is convenient, high efficiency, insert in interior square pipe 1 outside pipe 9, spacing boss 2 on the interior square pipe can form the effect that transition fit played the limit position with outside pipe boss 10, contact boss 3 and the contact of 9 inner chambers of outside pipe during the use, guarantee overall structure's stability.
