Description
Technical field
The utility model relates to a kind of ascending tool, is specifically related to a kind of bamboo-type insulated extension ladder.
Background technology
In the environment of power construction operation, often require to ascend a height livewire work, existing truck work is generally large chiThe ladder of very little, aluminium alloy or bamboo wood quality, carries transport inconvenience, and does not have insulation function, the security that impact is used.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of bamboo-type insulated is providedExtension ladder, easy to carry, use safety.
Bamboo-type insulated extension ladder described in the utility model, comprises left and right two root posts, and some horizontal strokes are housed between two columnsBar, column is pegged graft and is formed successively from top to bottom by some hollow stem, and the diameter of hollow stem increases from top to bottom successively, in everyOn blank pipe, be all set with spacer, adapter sleeve is equipped with in the upper end of every hollow stem, and cross bar two ends are contained on corresponding adapter sleeve; HorizontalBar two ends are provided with Telescopic positioning device, and Telescopic positioning device comprises linkage section, spring, moving pin and press element, linkage sectionOne end is connected with cross bar, and the other end is connected with adapter sleeve, has mounting groove in linkage section, and spring and movement are housed in mounting groovePin, moving pin one end is connected with spring, and the other end is through adapter sleeve, and moving pin stage casing diameter is less than the diameter at two ends, pressesElement comprises steady pin, pressing lever and gangbar, and steady pin is contained in mounting groove, and gangbar coordinates with moving pin stage casing; OftenRoot hollow stem lower end is equipped with locating hole near cross bar one side; Hollow stem, cross bar, adapter sleeve and spacer are by insulating materials systemBecome.
When use, gently draw the cross bar of extension ladder upper end, hollow stem with on move, stretching extension ladder is to proper height, makes mobilePin inserts in locating hole, and fixing extension ladder, and entirety employing insulating materials, use safety; When not in use, press flexibleThe pressing lever of detent mechanism, press element entirety is rotated around steady pin, and gangbar is rotated, thus moving pin moves back from locating holeGo out, hollow stem moves down returns, extension ladder reinstatement state, and now volume is small and exquisite, is convenient for carrying; Spacer makes adjacent two horizontal strokesRetention gap between bar, prevents extruding finger in the time of extension ladder return.
A described cross bar is bottom provided with magic tape, and the used time is not bound all cross bars, is easy to carry.
One end that described gangbar coordinates with moving pin stage casing, for circular, facilitates gangbar to drive moving pin.
Described column bottom is provided with Anti-slip cover, places stable.
Described cross bar upper surface is provided with anti-skid design, while preventing ascending stair, skids.
The beneficial effect that the utility model compared with prior art had is:
Bamboo-type insulated structure of telescopic ladder is simple, adopts stretching structure, and is equipped with magic tape, and volume is little to be convenient for carrying, and adoptsTelescopic positioning device, easy to use, entirety adopts insulating materials to make, safe and reliable.
