Abstract
The utility model relates to a portable multifunctional insulation ladder, including three side ladders (1, 1' and 1''), wherein the top parts of the three side ladders are hinged together. The side ladders (1, 1' and 1'') comprises two ladder beams (2) and a plurality of footplates (3) which connect the ladder beams (2); the top parts of the beam (2) of the side ladders (1, 1' and 1'') are connected through a pressure spring (4); and a connecting angle of the side ladders (1, 1' and 1'') can be arbitrarily adjusted and fixed within the range from 0 DEG to 180 DEG through a adjusting bar (5) of the pressure spring (4 and 4'). As a result, the utility model has advantages of light weight, small volume, insulation and easy to be carried. Therefore, the utility model is widely applied in the electric power industry, the telecommunication industry, the broadcasting industry and the television industry etc.
Description
Technical field
The utility model relates to a kind of ladder, more particularly it be a kind of can three sections folding portable multifunctional insulating ladders.
Background technology
The problem of a present work high above the ground of ubiquity in industries such as electricity meter-reading, telecommunications maintenance and radio and television, way is in the past carried double ladder or balladeur train ladder exactly.A kind of insulation ladder for dual-purpose of folding-straightening is disclosed as Chinese patent ZL00231577.7, though this ladder has had certain improvement to traditional double ladder, but in use exist following deficiency equally: (1) this ladder only is a kind of two sections dual-purpose insulating ladders that folding is straight, therefore highly generally lower, need carry out operation in higher construction part for the staff and cause restriction.(2) inconvenience is carried, and two sections folding back length are still bigger, carry inconvenience, and are not exclusively used in the parts that carry.(3) the terraced back portion of side ladder rolls over that to be connected wear intensity with latch and pin-and-hole coupling when straight big, and latch is lost easily.Therefore the staff in use still exists very big inconvenience.
Summary of the invention
The purpose of this utility model provide a kind of can three sections the straight portable multifunctional insulating ladders of folding.
For achieving the above object, the utility model is taked following design scheme: a kind of portable multifunctional insulating ladder, it comprises three side ladder 1,1 ＇, 1 that the top is hinged "; described side ladder 1,1 ＇, 1 " comprises two terraced beams 2 and connects several pedals 3 of two terraced beams 2, connection angle between its special feature is described side ladder 1,1 ＇, 1 " terraced beam 2 tops between connect described side ladder 1,1 ＇, 1 by stage clip 4 " can be regulated and fixing and locking by the adjusting rod on the stage clip 45 in 0-180 ° of scope as required.
Side ladder 1 " two terraced beam 2 tops coupling two insulation hooks 6 are arranged.Insulation hook 6 can the reinforced insulation ladder with the dependence thing between degree of connection, degree of safety was improved when the staff worked.
At least one side ladder 1,1 ＇, 1 " the side of at least one terraced beam 2 handle 7 is installed.Handle 7 both can be portable, also can hang on bicycle or the motorcycle, brings great convenience when carrying for electricity meter-reading, post and telecommunications maintenance and broadcast television industry staff.
Terraced beam 2 bottom mating of side ladder 1 have thickening electro-insulating rubber pad 8, and electro-insulating rubber pad 8 has increased the abrasion resistance of ladder, has improved safety factor simultaneously.
Ladder beam 2, pedal 3, electro-insulating rubber pad 8 surfaces are evenly equipped with and are the alternate groove of convex-concave.These grooves have increased the abrasion resistance of ladder, have improved the safety factor the when staff works simultaneously.
" when being aluminium alloys, this insulating ladder is in light weight, and intensity is big, side ladder 1,1 ＇, 1 " good insulation preformance when being this material for side ladder 1,1 ＇, 1.
Number according to different need of work side ladders also can have increase: as increase to 4 or 5, in addition more.
The utility model is simple in structure, and volume is little, and is easy to carry, can regulate to be double ladder, be used for highly lower, the occasion of the thing of having no backing; Can also regulate and be " bridge shape ", be used for hanging or stacking article, can also work as vertical ladder and be used for higher construction site, will be widely used in industries such as electric power, telecommunications, radio and television.
Description of drawings
Fig. 1 is the utility model vertical ladder view,
Fig. 2 is the utility model folded state schematic diagram,
Fig. 3 is another kind of folded state (bridge shape) schematic diagram of the utility model,
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, the utility model advantage noted earlier will become easier to understand.
1,1 ＇, 1 in the accompanying drawing " expression side ladder, the terraced beam of 2 expressions, 3 expression pedals, 4, the expression stage clip, 5 expression adjusting rods, 6 expression insulation hooks, 7 expression handles, 8 expression electro-insulating rubber pads, 9 expression reinforced company parts.
From Fig. 1, Fig. 2, Fig. 3 as can be known: this portable multifunctional insulating ladder, connect by stage clip 4 between it comprises three three side ladders, 1,1 ＇, 1 that the top is hinged "; each side ladder includes two terraced beams 2; and connect several pedals 3 of two terraced beams 2; between side ladder 1,1 ＇, side ladder 1 ＇, 1 ".When being in folded state, need transfer when being the vertical ladder state the utility model portable multifunctional insulating ladder, at this moment progressively regulate the adjusting rod 5 on the stage clip 4, make between side ladder 1,1 ＇, side ladder 1 ＇, 1 " between be in 180 ° of states, then the utility model is the vertical ladder state.In like manner, also the portable multifunctional insulating ladder that is in the vertical ladder state can be transferred to various folded states.Side ladder 1 " two terraced beam 2 tops coupling two insulation hooks 6 are arranged, this insulation hook 6 can the reinforced insulation ladder with the dependence thing between being connected, the safety the when staff is worked is improved.Be easy to carry after three sections of side ladders 1 " terraced beam 2 sides one handle 7 is arranged, its purpose is side ladder 1,1 ＇, 1 " are folding, both can be portable, also can hang on bicycle or the motorcycle.Need to prove handle 7 also can be installed in other side ladder 1,1 ＇, other terraced beam 2 on.The bottom of side ladder 1, side ladder 1 " top coupling thickening electro-insulating rubber pad 8 is arranged; terraced beam 2, pedal 3, electro-insulating rubber pad 8 are evenly equipped with and are the alternate groove of convex-concave; these grooves have increased the abrasion resistance of ladder; improved the safety factor the when staff works, and also make ladder integral body seem better appearance simultaneously.
" when being aluminium alloys, this insulating ladder is in light weight, and intensity is big, side ladder 1,1 ＇, 1 " good insulation preformance when being wood materials for side ladder 1,1 ＇, 1.
Between ladder beam 2 and the pedal 3 reinforced company's part 9 is arranged, its effect is a bonding strength of strengthening terraced beam 2 and pedal 3, makes the intensity of ladder reach to take advantage of and carries more than the 95KG.Guarantee staff's safety.Need to prove that reinforced company's part 9 is not limited in position described in the accompanying drawing, also can be installed in as required on other terraced beam 2 and the pedal 3.
Need to prove: for one of ordinary skill in the art, under the prerequisite of the utility model spirit and thought, can also make other improvement or modification to the utility model, this belongs to protection domain of the present utility model equally.
