Abstract
The invention discloses a herringbone ladder. The herringbone ladder comprises a top plate, two vertical ladders and a fixing rod, wherein the two vertical ladders are symmetrically arranged; each vertical ladder comprises two opposite ladder beams and a plurality of rungs between the two ladder beams; top ends of the ladder beams are rotationally arranged at two ends of the top plate; braking trundles are arranged at bottom ends of the ladder beams; the fixing rod is a telescopic rod, one end of the telescopic rod is fixed in the center of the lower surface of the top plate, and a base is arranged at the other end of the telescopic rod. Accordingly, the herringbone ladder can be prevented from turning on one side when used, the safety of a user is improved, the herringbone ladder is convenient to move, time and labor are saved, and the height of the herringbone ladder can be adjusted according to actual conditions.
Description
Technical field
The present invention relates to ladder field, particularly relate to a kind of double ladder.
Background technology
Along with growth in the living standard, the requirement of people to quality of life is more and more higher, is often in and adds a lot of ornament.Therefore, in daily life, the maintenance work of ornament increases gradually, and the use of double ladder is also more and more frequent.The mode that existing double ladder adopts two terraced frames hinged mostly completes rise from operation, and for the people of operation alone and the crowd of some trick inconvenience, this double ladder seems very dangerous, ladder stabilizer is poor, easily to turn on one's side, there is certain potential safety hazard, and ladder moves, and wastes time and energy extremely inconvenient.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of double ladder, can avoid turning on one's side in use procedure, improves the safety of user, and conveniently moving, time saving and energy saving, can also according to the height of the situation adjustment double ladder of reality, structure is simple, uses easily.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of double ladder, comprising: top board, vertical ladder and fixed bar; Described vertical ladder has two, and two vertical ladders are symmetrical arranged; Some transverse slats that described vertical ladder comprises two relative terraced beams and is arranged between two terraced beams, the rotating two ends being arranged on described top board, the top of terraced beam, the bottom of terraced beam is provided with brake castor; Described fixed bar is expansion link, and expansion link one end is fixed on the center of described top board soffit, and the expansion link other end is provided with base.
Preferably, described expansion link comprises fixed bar and lower fixed bar, and upper fixed bar lower surface has screwed hole, and outer ring, lower fixed bar top is provided with external screw thread, and external screw thread and corresponding threaded holes close.
Preferably, described transverse slat is rectangular slab.
The invention has the beneficial effects as follows: the present invention can avoid turning on one's side in use procedure, improve the safety of user, and conveniently moving, time saving and energy saving, can also according to the height of the situation adjustment double ladder of reality.

In accompanying drawing, the mark of each parts is as follows: 1, top board; 2, vertical ladder; 3, expansion link; 4, brake castor; 5, base.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:
A kind of double ladder, comprising: top board 1, vertical ladder 2 and fixed bar; Described vertical ladder 2 has two, and two vertical ladders 2 are symmetrical arranged; Some transverse slats that described vertical ladder 2 comprises two relative terraced beams and is arranged between two terraced beams; The rotating two ends being arranged on described top board 1, top of ladder beam, can open double ladder; The bottom of ladder beam is provided with brake castor 4, and can move double ladder, time saving and energy saving easily, brake castor 4 can also be fixed self after opening double ladder, anti-sliding stop, to use; Transverse slat is rectangular slab, can be convenient to user and climb double ladder, improves the lifting surface area of user's sole, prevents from occurring skidding in climbing process, cause personal damage; Described expansion link 3 comprises fixed bar and lower fixed bar, upper fixed bar lower surface has screwed hole, outer ring, lower fixed bar top is provided with external screw thread, external screw thread and corresponding threaded holes close, lower fixed bar can in precession in fixed bar, the difference of the precession degree of depth can change the height of expansion link 3 entirety, can regulate according to the height of double ladder to expansion link 3, makes expansion link 3 well support double ladder; The upper surface of fixed bar is fixed on the center of described top board 1 soffit, and support double ladder that can be more stable, to reach optimum efficiency; Described lower fixed bar bottom is provided with base 5, and base 5 is heavier, and double ladder can be made more stable, prevents rollover.
The present invention can avoid turning on one's side in use procedure, improves the safety of user, and conveniently moving, time saving and energy saving, can also according to the height of the situation adjustment double ladder of reality, structure is simple, uses easily.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
