Abstract
The invention relates to a dual-purpose insulated ladder. The dual-purpose insulated ladder comprises a ladder body. Armrest frames bent into triangle shapes are vertically and symmetrically disposed at left and right sides of the top of the ladder body. Landing legs I extend symmetrically and slantingly downwards from one ends of the bottom edges of the armrest frames, and the other ends of the armrest frames are rotationally connected to a rotation shaft. Two ends of the rotation shaft are connected to landing legs II. The landing legs II are provided with radial limiting bolt holes. The bottom edges of the two armrest frames are provided with locking plates inclined upwards and downwards. The locking plates are provided with limiting bolts that can be inserted into the limiting bolt holes in the landing legs II. The bottom edges of the armrest frames are connected by a cross supporting rod, the bevel edges of the armrest frames are connected by a cross supporting rod, the two landing legs I are connected by cross supporting rods, and the landing legs II are connected by a cross supporting rod. The beneficial effects of the dual-purpose insulated ladder are that the dual-purpose insulated ladder can be used as a ladder when climbing is needed, and can be used as a chair in normal times, thus saving space and largely increasing the utilization rate; and using of the dual-purpose insulated ladder is convenient and safe.
Description
Technical field
The present invention relates to a kind of dual-purpose insulating ladder.
Background technology
Can insulating ladder be used in power industry, especially often use when transformer station is checked and keep in repair the energy meter of two layers, cupboard.But traditional insulating ladder is heavier, be inconvenient to move, and the needs of shelving of insulating ladder take up room, become burden.Because human body adds the height of arm generally at about 2.1 meters, conventional chair height is 0.4 meter, the height that both add up is about 2.5 meters, insufficient height when therefore utilizing conventional chair to ascend a height, if to stack up use with two chairs, then need other people to help, use both inconvenient, also dangerous.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of easy to use, the dual-purpose insulating ladder in joint space-efficient.
The present invention is achieved by the following measures:
The dual-purpose insulating ladder of one of the present invention, comprise terraced body, the left and right sides, described terraced body top is vertically symmetrically arranged with and is bent into leg-of-mutton handrail frame, one end, two handrail frame bases obliquely symmetry is extended with supporting leg I, rotating shaft is rotatably connected between two handrail frame base other ends, described rotating shaft two ends are connected with supporting leg II, supporting leg II is provided with radial caging bolt hole, two handrail frame bases are provided with lockplate obliquely and obliquely, described lockplate are provided with the caging bolt that can penetrate in supporting leg II upper limit bolt hole; All support bar is horizontally connected with between the base of two handrail frames and hypotenuse, between two supporting legs I and between two supporting legs II.
Above-mentioned lockplate is positioned at the outside of supporting leg II, and the lockplate of homonymy is divided into ladder lockplate and seat lock
Determine plate, ladder lockplate parallels with the hypotenuse of handrail frame.
Integrally be bent with the bracing piece that overlaps below above-mentioned handrail frame base, described bracing piece is integrated with supporting leg I and is connected.
The invention has the beneficial effects as follows: can use as ladder when needing to ascend a height, can use as chair again at ordinary times, save space, its utilization rate is improved greatly, use also convenient safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention when using as ladder.
Fig. 2 is the structural scheme of mechanism of the present invention when using as chair.
Wherein: 1 handrail frame, 2 supporting leg I, 3 supporting leg II, 4 rotating shafts, 5 support bars, 6 ladder lockplates, 7 seat lockplates.
Detailed description of the invention
Below in conjunction with accompanying drawing, further detailed description is done to the present invention:
The dual-purpose insulating ladder of one of the present invention, not only can use as ladder, and just can be used as seat by lockover simply.Improve the utilization rate of insulating ladder, save space.
As shown in Figure 1, be the structural representation of the present invention when using as ladder.It comprises terraced body, the ladder left and right sides, body top is vertically symmetrically arranged with and is bent into leg-of-mutton handrail frame 1, one end, two handrail frame 1 bases obliquely symmetry is extended with supporting leg I 2, rotating shaft 4 is rotatably connected between two handrail frame 1 base other ends, rotating shaft 4 two ends are connected with supporting leg II 3, supporting leg II 3 is provided with radial caging bolt hole, two handrail frame 1 bases are provided with lockplate obliquely and obliquely, lockplate are provided with the caging bolt that can penetrate in supporting leg II 3 upper limit bolt hole; Support bar 5 is all horizontally connected with between the base of two handrail frames 1 and hypotenuse, between two supporting legs I 2 and between two supporting legs II 3.Lockplate is positioned at the outside of supporting leg II 3, and the lockplate of homonymy is divided into ladder lockplate 6 and seat lockplate 7, and ladder lockplate 6 parallels with the hypotenuse of handrail frame 1.Handrail frame 1 is integrally bent with the bracing piece that overlaps below base, and bracing piece is integrated with supporting leg I 2 and is connected.When doing ladder use, supporting leg II 3 forwards below to and locks with the caging bolt on ladder lockplate 6, such supporting leg I 2 and supporting leg II 3 are as the support section of ladder, supporting leg II 3 and the hypotenuse of handrail frame 1 are in a plane tilted simultaneously, as the climbing face of ladder, handrail frame 1 at top as handrail, can also play booster action.Support bar 5 between two supporting legs II 3 and between handrail frame 1 is just as the pedal cross bar of ladder.
As shown in Figure 2, structural scheme of mechanism when the present invention uses as chair.Be exactly that the insulating ladder in Fig. 1 is inverted, supporting leg II 3 is rotated to below simultaneously, and lock with the caging bolt on seat lockplate 7, thus supporting leg I 2 just becomes the chair back of seat, handrail frame 1 and supporting leg II 3 become seat leg, and the support bar 5 place plane originally between handrail frame 1 base just can as seat.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
