Abstract
The utility model provides a kind of pipe guardrail connector, including expansion head, expanding tense machine, housing screw, after expanding tense machine is placed in pipe with expansion head, housing screw is screwed into from collet threaded hole, make the round four paws of expansion head be strutted by the horn mouth of expanding tense machine one end to become larger, to realize the close connection between guardrail pipe with guardrail round tube inner wall clamping.The utility model is skillfully constructed, is simple in structure, applicability is wide, can be widely applied to the staircase in various industrial production regions, walks on stage, the manufacturing of platform metal protection fence, has very high promotional value and economic benefit.
Description
Technical field
The utility model is related to aircraft assembling manufacturing technical field, especially a kind of pipe guardrail for working stand connects
Head.
Background technology
In each row industrial production region, have many movable metallic staircases, walk on stage, platform etc. will be installed around platform
Safety protective fence prevents personnel from falling for closing climbing space around table top.Traditional pipe guardrail is mostly pipe welding
Structure, circular tube end face will cut intersection before welding, and postwelding weld seam will also carry out grinding process again.Whole process is time-consuming and laborious, together
When there are aesthetics it is insufficient, maintainable not strong the problems such as, and exist it is not restructural after the completion of construction, will be to original if you need to change
Construction carries out long period transformation and correctional effect is very poor, has not met the development such as " flexibility is reconfigured quickly " of tooling profession
Vision.
Invention content
The purpose of this utility model is to provide a kind of link that can quickly assemble the metal circular tube used in safety barrier
Device, abbreviation guardrail connector.The technical process of bend pipe and welding is eliminated, guardrail production efficiency is effectively improved.And according to
The a variety of joint forms of Demand Design are actually used, different guard bar structure demands is met.
A kind of pipe guardrail connector, including expansion head, expanding tense machine, housing screw, expansion head are the thick circle in the thin rear end in front end
Platform tubular member, front end are four paws structure, outer diameter and pipe guardrail internal diameter clearance fit, and rear portion tube wall is equipped with collet threaded
Hole, expanding tense machine are the thick intermediate thin rotary body in both ends, and one end is the bell-mouth structure of air of 30 ° of gradient, and the other end is the cone of 45 ° of gradient
After shape structure, with expansion head front end four paws respective outer side edges, be pressed into guardrail pipe, housing screw is headless screw, expanding tense machine with
After expansion head is placed in pipe, housing screw is screwed into from collet threaded hole, makes the round four paws of expansion head by expanding tense machine one end
Horn mouth, which struts, to become larger, to realize the close connection between guardrail pipe with guardrail round tube inner wall clamping.
The utility model has the advantage of be skillfully constructed, simple in structure, applicability is wide, can be widely applied to various industry
The staircase of production area is walked on stage, the manufacturing of platform metal protection fence, has very high promotional value and economic benefit.
Description of the drawings：
The utility model is further illustrated with example below in conjunction with the accompanying drawings
Fig. 1 is diversified forms guardrail connector schematic diagram；
Fig. 2 is the shaft side figure of the utility model；
Fig. 3 is the principles of the present invention schematic diagram；
Explanation is numbered in figure：1- expansion heads, 2- expanding tense machines, 3- housing screws, 4. guardrail pipes.
Specific implementation mode
According to Fig. 1-3, a kind of pipe guardrail connector, including expansion head 1, expanding tense machine 2, housing screw 3, before expansion head 1 is
It is four paws structure, outer diameter and 4 internal diameter clearance fit of guardrail pipe, rear portion tube wall to hold the round platform tubular member that thin rear end is thick, front end
It is equipped with collet threaded hole, expanding tense machine 2 is the thick intermediate thin rotary body in both ends, and one end is the bell-mouth structure of air of 30 ° of gradient, another
End is the pyramidal structure of 45 ° of gradient, and after 1 front end four paws respective outer side edges of expansion head, in indentation guardrail pipe 4, housing screw 3 is
Headless screw, after expanding tense machine 2 is placed in pipe with expansion head 1, housing screw 3 is screwed into from collet threaded hole, makes the circle of expansion head 1
Shape four paws is strutted by the horn mouth of 2 one end of expanding tense machine to become larger, thus with the 4 inner wall clamping of guardrail pipe, between realization guardrail pipe 4
Close connection.
Guardrail in an assembling process, first combines the expansion head of guardrail connector 1, expanding tense machine 2, housing screw 3, at this time
Housing screw 3 does not head into the conical surface of 2 rear end of expanding tense machine, and the four paws of expansion head is not softened.Then as Fig. 2 will combine
Connector fill in pipe 4.After the section of pipe 4 heads into 1 root of expansion head, then housing screw 3 is tightened and heads into swelling
After the conical surface of 2 rear end of device, expanding tense machine 2 is pulled inward the fashionable four paws by expansion head 1 and struts, thus the inner wall clamping with pipe 4,
Realize the connection of pipe and guardrail connector.There are many structure types for guardrail connector as shown in Figure 1, can meet different types of shield
Column requirements of combination.
Claims (1)
