Detailed description of the invention
Fig. 1 shows, and the utility model is made up of built-in pipe 1, intermediate bar 2, push rod 3, and built-in pipe 1, intermediate bar 2 and push rod 3 is interconnective tube-in-tube structure, and the length of intermediate bar 2 and push rod 3 is less than the length of built-in pipe 1, can be contained in built-in pipe 1 by telescopic.There is the securing pothook 4 connecting warning tape or fence mesh in push rod 3 upper end, push rod 3 is also provided with the Removable hook 13 connecting warning tape or fence mesh.
Fig. 2,3 displays, securing pothook 4 is made up of back-up ring 5, clamping plate 6.The sidewall of push rod 3 upper end has the plane caved inward, and the height of recession plane and the width of warning tape match, and install clamping plate 6 outside recession plane.The medial surface of clamping plate 6 and recession plane close contact, the lateral surface of clamping plate 6 is the circular arc matched with push rod 3 circumference, the lower end of clamping plate 6 has the cave in push rod wall of lower end of rotating shaft 7 and push rod 3 to be connected, the plate face of clamping plate 6 outwards and inwardly can be rotated around rotating shaft 7, to clamp and to unclamp warning tape.
Fig. 2,3 displays, clamping plate 6 are fixed by back-up ring 5 after clamping, and clamping plate 6 can not outwards be opened.The structure of its back-up ring 5 is, the annular groove 8 around push rod 3 circumference is had above push rod 3 recession plane, there is annular protrusion 9 to the inside the upper end of back-up ring 5, back-up ring 5 is enclosed within push rod 3 top, the annular protrusion 9 of back-up ring 5 is embedded in the annular groove 8 of push rod 3 upper end, and back-up ring 5 can not be able to move up and down around push rod 3 circular-rotation.The gap 10 of level is arranged at back-up ring 5 bottom, and the top edge of gap 10 is higher than the top of clamping plate 6, and the width of gap 10 and the width of clamping plate 6 match.When back-up ring 5 forwards gap 10 position corresponding with clamping plate 6 to, clamping plate 6 outwards can be opened from gap 10, at this moment warning tape can be placed, the clamped position that clamping plate 6 inwardly rotate, rotate back-up ring 5, the part of gap that do not have of back-up ring 5 forwards to outside clamping plate 6, and at this moment the lower limb of back-up ring 5 is lower than the upper end of clamping plate 6, block clamping plate 6 can not outwards rotate, even if clamping plate 6 clamp warning tape.
Fig. 4 shows, the recession plane of push rod 3 there are multiple clamping recess 12 of vertical parallel arrangement, clamping recess 12 is uniform along plane, the medial surface of the clamping plate 6 relative with recession plane there are corresponding multiple clampings protruding 11, the clamping recess 12 of recession plane is meshed with the clamping projection 11 of clamping plate 6 medial surface, can play raising frictional force, prevent warning tape by the effect extracted.
Fig. 5,6 displays, push rod 3 is also provided with the Removable hook 13 connecting warning tape or fence mesh, Removable hook 13 is made up of sleeve pipe 14, locknut 15.Sleeve pipe 14 is sleeved on push rod 3, and sleeve pipe 14 can slide up and down at push rod.There is external screw thread sleeve pipe 14 upper end, and locknut 15 is screwed in sleeve pipe 14 upper end.The parallel gap that two vertical is had in the side of sleeve pipe 14 wall, two gap upper ends are positioned at the externally threaded bottom of sleeve pipe 14, be connected by level trough between two gap upper ends, two sleeve portions between gap and level trough are hook 16, and warning tape hangs on hook 16.When locknut 15 upwards unscrews disengaging, the level trough linking up with 16 upper ends exposes, and at this moment warning tape can be inserted into downwards the hook 16 between two gap from level trough.Be screwed down locknut 15 after being plugged warning tape, the lower limb of locknut 15 covers the level trough of hook 16 upper end downwards, and warning tape can not prolapse upwards, keeps being connected firmly.
Fig. 5,6 displays, sleeve pipe 14 external diameter of sleeve pipe 14 external screw thread bottom is greater than sleeve pipe 14 major diameter of external thread, tapered circumferential surface 17 transition is had between sleeve pipe 14 outer wall and sleeve pipe 14 external screw thread, the outward-dipping conical surface 18 is arranged at the bottom of locknut 15 endoporus, and the tapered circumferential surface 17 of sleeve pipe 14 outer wall matches with the conical surface 18 of locknut 15 endoporus bottom.When locknut 15 is screwed down, the conical surface 18 of locknut 15 endoporus bottom, to the tapered circumferential surface 17 of lower compression sleeve pipe 14 outer wall, inwardly compresses hook 16 simultaneously, makes the medial surface of hook 16 compress warning tape, plays the effect be connected firmly.
Fig. 7 show, on built-in pipe, 1 end has connecting ring 21, connecting ring 21 inner and outer wall all have screw thread.There is nylon end socket 19 on the top of built-in pipe 1, and nylon end socket 19 is screwed on the external screw thread of built-in pipe upper end connecting ring 21, has rubber gasket 20 below nylon end socket 19.The internal thread of connecting ring 21 matches with the external screw thread of intermediate bar 2 lower end, and the lower end of intermediate bar 2 can be connected with built-in pipe 1 upper end connecting ring 21.
Fig. 8 shows, and intermediate bar 2 and push rod 3 are completed by check lock lever 22 and stay 23.Cylindrical check lock lever 22 is connected to the lower end of push rod 3, check lock lever 22 outer wrapping stay 23, and stay 23 is sliding-contact with the cylindrical outer wall part of check lock lever 22.Stay 23 is the sheet rubber of two semi-circular cylindrical, and the relative both sides of cylindrical check lock lever 22 are plane respectively to sunken inside, only has the other both sides circular arc of cylinder to contact with sheet rubber, and the thickness of sheet rubber is radially in increasing gradually.Check lock lever 22 rotates along with push rod 3, and its both sides circular arc relatively rotates, and when turning to the thinner thickness place of sheet rubber, the inwall of sheet rubber and intermediate bar 2 is in loosening state, and push rod 3 and intermediate bar 2 can pull up and down, stretch; When turning to the thickness thicker part of sheet rubber, the inwall close contact of sheet rubber and intermediate bar 2, can not pull up and down, realizes push rod 3 and intermediate bar 2 is locked, and therefore push rod 3 and intermediate bar 2 can be locked at any relative position, reach the height of needs.
Built-in pipe 1 of the present utility model is high temperature resistant, low temperature resistant, withstand voltage PPR shape material, and intermediate bar 2 and push rod 3 are the good glass reinforced plastic pipe that insulate.An embodiment of the present utility model is of a size of: the diameter 65mm of built-in pipe 1, height 700mm, thickness of pipe wall 5mm; The external diameter 32mm of intermediate bar 2, internal diameter 28mm, height 550mm; Push rod 3 external diameter 26mm, internal diameter 22mm, height 500mm.
