The orientation or position relationship shown, it is for only for ease of description the utility model and simplifies description, rather than indicates or imply and be signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
The utility model is described in further detail below by specific embodiment.
The utility model provides a kind of retractable Telescopic guardrail, as shown in figure 1, including guardrail 1, guard bar support saddle 2, interior
Pipe support arm 3 and governor motion 4.
The both sides of guardrail 1 are provided with outer tube support arm 11, and the outer tube support arm 11 of the both sides of guardrail 1 is parallel to each other, edge on outer tube support arm 11
The line of rabbet joint 12 for extending to end axially is provided with, for leaving surplus when outer tube support arm 11 is in banding inner tube support arm 3, the line of rabbet joint 12 is right
Title is arranged on the both sides of outer tube support arm 11;In the present embodiment, cross bar 13 is provided between the outer tube support arm 11 of guardrail 1, cross bar 13 is located at
The top of the line of rabbet joint 12, for strengthening the structural stability and security of guardrail 1.
Guard bar support saddle 2 is fixed in using area, and inner tube support arm 3 is hinged with guard bar support saddle 2, for realizing folding and unfolding work(
Can, it is bleed position when inner tube support arm 3, which turns to, to be erected, it is retrieving position to turn to when lying low, edge on inner tube support arm 3
The chute 31 for extending to top axially is provided with, for the slip of governor motion 4, the top of inner tube support arm 3 extend into outer tube support arm 11
Bottom;In the present embodiment, the wear washer 5 of semicircular in shape is provided between outer tube support arm 11 and inner tube support arm 3, for reducing sleeve pipe
Between gap increase thrust, the straight bent angle of one end band of wear washer 5, the line of rabbet joint 12 of straight bent angle insertion outer tube support arm 11.
As shown in Figures 2 to 4, governor motion 4 is used to realize Telescopic, and it includes slide bar 41, left clip 42, right clip
43 and eccentric cam 44, slide bar 41 is through outer tube support arm 11 and is removably attached to the end of outer tube support arm 11, slide bar 41 and groove
Mutually avoided between seam 12, it is preferred that the axis of slide bar 41 and the line of the line of rabbet joint 12 are perpendicular.Left clip 42 and right clip 43 are respectively provided with
