Abstract
The utility model relates to a double ladder specifically is a take handrail double ladder, includes two terraced framves of articulated, connection treads, backup pad and connection the cushion in terraced rest base portion of connection on the ladder puts up the side on the ladder frame, one be equipped with the round hole on the ladder frame side, be equipped with the spout on another ladder frame of homonymy, be equipped with the round hole more than two in ladder frame and the backup pad, the backup pad is passed through the bolt and is connected with round hole and spout respectively, be equipped with the straight board rather than bolted connection in the backup pad, straight board top is equipped with the handrail, be equipped with the couple on the straight board side, be equipped with the nut on the bolt, the application of the utility model relates to a beneficial effect lies in: constructor stands when the higher department of ladder, can adjust the height of handrail, the constructor of being convenient for holds, holds the handrail, the people stands the shakiness and rocking of producing in the time of can avoiding the focus higher, has eliminated the potential safety hazard.
Description
Technical field
The utility model relates to a kind of double ladder, is specially a kind of Armrest double ladder.
Background technology
Double ladder is a kind of very conventional ascending tool in construction working, because of its use time, the terraced bar of front and back and ground form an isosceles triangle, look like ' people ' word, calling ' double ladder ' thus its image.Practical double ladder has fixing double ladder and moving herringbone ladder; Fixing double ladder is that people build instrument temporarily, and movable double ladder is connected together by the top loose-leaf of two ladders, can altogether, due to its flexibility, therefore be widely used when movement.But Problems existing is: when constructor stands in ladder higher position, the position of centre of gravity of constructor is higher, does not protect accordingly again above ladder, therefore there is certain potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of Armrest double ladder guaranteeing constructor's safety.
To achieve these goals, a kind of Armrest double ladder that the utility model provides, comprises two hinged ladders, the tread be connected on ladder, the rubber cushion that is connected to the gripper shoe on ladder side and is connected to bottom ladder; Described in one, ladder side is provided with circular hole, another ladder of homonymy is provided with chute, described ladder and gripper shoe are provided with plural circular hole, described gripper shoe is connected with circular hole and chute respectively by bolt, described gripper shoe is provided with bolted straight plate with it, described straight plate top is provided with handrail, and described straight plate side is provided with hook, and described bolt is provided with nut.
Compared with prior art, the advantage of this programme is: described gripper shoe and two ladders surround a triangle, and described gripper shoe is connected with screwed hole by bolt, then fixes with nut, compared to general triangle ladder, has better stability; Be provided with rubber cushion bottom described ladder, increase the frictional force on ladder and ground, make ladder more firm; When constructor stands in ladder higher position, because position of centre of gravity is higher, easily rock, constructor can hold handrail, and described ladder and gripper shoe are provided with plural screwed hole, for regulating the height of gripper shoe, thus the height of adjustable handrail, make that constructor is more convenient to hold, more firmly stand on ladder, described hook can be used for hanging the instrument of lighter in weight or material, thus eliminates potential safety hazard.
As preferred scheme, described circular hole is screwed hole, makes the connection of bolt and ladder more firm.
As preferred scheme, described hook is bolted on straight plate, is convenient to dismounting and assembling.
As preferred scheme, described straight plate is arranged at outside chute, and when drawing ladder in, straight plate overlaps with ladder, is convenient to dismounting and the storage of straight plate and gripper shoe.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of Armrest double ladder of the present utility model.
Fig. 2 is the right view of Armrest double ladder of the present utility model.
Fig. 3 is the top view of Armrest double ladder of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated;
As shown in Figure 1, Armrest 4 double ladder of the present utility model, comprises ladder 1, tread 2, screwed hole 3, handrail 4, hook 5, straight plate 6, nut 7, bolt 8, rubber cushion 9, gripper shoe 10, chute 11.
As shown in Figure 1, Figure 2, Figure 3 shows, two ladders 1 are hinged, in order to realize gathering and the expansion of two ladders 1, ladder 1 arranged multiple tread 2, are surrounded by rubber cushion 9 bottom ladder 1, increase the frictional force on ladder 1 and ground, ladder 1 side is provided with multiple screwed hole 3, gripper shoe 10 is provided with corresponding screwed hole 3, the height of gripper shoe 10 can be regulated, thus the height of adjustable handrail 4, another ladder 1 of homonymy is provided with chute 11, gripper shoe 10 one end is linked together by bolt 8 and the screwed hole 3 on ladder 1, chute 11 li arranges a bolt 8, bolt 8 is connected with the other end of gripper shoe 10, straight plate 6 is connected on same bolt 8 with gripper shoe 10, straight plate 6 top is provided with the handrail 4 being parallel to ground, straight plate 6 side is connected with hook 5 by bolt 8, above-mentioned bolt 8 is all by nut 7, fixing straight plate 6 is arranged at outside chute 11, when drawing ladder 1 in, straight plate 6 overlaps with ladder 1, be convenient to dismounting and the storage of straight plate 6 and gripper shoe 10.
As shown in Figure 1, ascend a height construction time, constructor according to construction needed for concrete height, regulate the angle of ladder 1, then by regulating the height of gripper shoe 10, thus determining the height of handrail 4, being then fixed with bolt 8 and nut 7, hook 5 can be used to hang lighter instrument or material, constructability human users, meanwhile, when constructor stand on ladder higher position, handrail 4 can be held, avoid the potential safety hazard that constructor causes because of crank.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
