Abstract
The utility model relates to a climbing article used in work and life, particularly to a herringbone ladder, which includes a first support rod and a second support rod, wherein both the first and the second support rods include two vertical rods and a plurality of cross bars connected between the two vertical rods. The herringbone ladder is characterized in that the upper ends of the first and the second support rods are movably connected through a connecting mechanism; and the connecting mechanism includes a rotating shaft, shaft sleeve sleeved on the outer side of the rotating shaft and an adjusting shaft sleeve sleeved on the outer side of the shaft sleeve. By adopting the structure, the herringbone ladder can retain a certain angle after being unfolded, and the unfolding angle between the two support rods is adjustable, therefore the stability and safety of the ladder are enhanced, and the side overturning is effectively prevented.
Description
Technical field
The utility model relates in a kind of work or the life climbs articles for use, a kind of specifically double ladder.
Background technology
Ladder is the instrument that often uses during ascend operation in people's routine work or the life, and during ascend operation, people often need vacate two hands and come operation; Therefore, very high for the stability requirement of ladder, but existing ladder often need lean against ladder on certain object; For example wall, pillar etc., but can not guarantee the fastness of ladder like this, double ladder; Become herringbone capable because open the back, its stability is better than general ladder, is particluarly suitable for using in the family; Relative power after double ladder opens through ladder between two bracing frames supports the use of ladder; But existing double ladder can not be guaranteed can remain on after two bracing frames open must angle, so the stability of ladder is not high, is easy to generate the danger of overturning.
Summary of the invention
The utility model is to solve the problems of the technologies described above the double ladder that can remain on certain angle after providing a kind of firm supporting, two bracing frames to open.
The utility model is that the technical scheme that the technical solution problem is adopted is:
A kind of double ladder; Comprise first support bar and second support bar; Described first support bar and second support bar include two vertical poles and are fixedly connected on many cross bars between two vertical poles; The upper end of described first support bar and second support bar is movably connected through bindiny mechanism; It is characterized in that: described bindiny mechanism comprises rotating shaft, be sleeved on the axle sleeve in the rotating shaft outside and be sleeved on the adjusting axle sleeve in the axle sleeve outside; Described first support bar and second support bar are fixedly connected on respectively on rotating shaft and the axle sleeve, and described axle sleeve is provided with through jointed shaft and is connected on the axle sleeve inner ring surface, protrudes in the locating part of axle sleeve inner ring surface, are fixedly connected in the said rotating shaft to be raised in rotating shaft surface and height of projection greater than the projection piece of locating part to the distance between the rotating shaft; One side of described locating part is provided with and stops locating part to a sideway swivel, be connected to the countercheck rod on the axle sleeve through jointed shaft equally, and the other end of described countercheck rod passes axle sleeve and is fixedly attached to regulating shaft and puts.
The external surface of described axle sleeve is provided with groove, and the outside of described adjusting axle sleeve is provided with an end and passes and regulate axle sleeve and be inserted to the pick-and-place components in the groove.
Owing to adopted said structure, the described a kind of double ladder of the utility model can remain on certain angle after opening, and the opening angle between two bracing frames is adjustable, has increased the stability and the safety of ladder, and effectively prevents rollover.

Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structure sectional view of the utility model syndeton part.
The specific embodiment
As shown in the figure, the described a kind of double ladder of the utility model comprises first support bar 1 and second support bar 2; Described first support bar 1 and second support bar 2 include two vertical poles and are fixedly connected on many cross bars between two vertical poles, also can install on the said cross bar and be convenient to step on the pedal of stepping on, and the upper end of described first support bar 1 and second support bar 2 is movably connected through bindiny mechanism; Described first support bar 1 and second support bar 2 can strut and be herringbone and place, and described bindiny mechanism comprises rotating shaft 3, be sleeved on the axle sleeve 4 in rotating shaft 3 outsides and be sleeved on the adjusting axle sleeve 5 in axle sleeve 4 outsides, and described axle sleeve 4 can be provided with two two ends that are set in rotating shaft 3; Described first support bar 1 and second support bar 2 are fixedly connected on respectively on rotating shaft 3 and the axle sleeve 4, annexation interchangeable between described first support bar 1, second support bar 2 and rotating shaft 3, the axle sleeve 4, and described axle sleeve 4 is provided with through jointed shaft and is connected on axle sleeve 4 inner ring surfaces, protrudes in the locating part 6 of axle sleeve 4 inner ring surfaces; Said locating part 6 is provided with a plurality of around the inner ring surface of axle sleeve 4; Be provided with the groove that can supply locating part rotation in the said axle sleeve 4, be fixedly connected in the said rotating shaft 3 and be raised in rotating shaft 3 surfaces and height of projection greater than the projection piece 8 of locating part 6 to the distance between the rotating shaft 3, said locating part 6 plays the effect that stops projection piece 8; One side of described locating part 6 is provided with and stops locating part 6 to a sideway swivel, the same countercheck rod 7 that is connected to through jointed shaft on the axle sleeve 4; The other end of described countercheck rod 7 passes axle sleeve 4 and is fixedly attached on the adjusting axle sleeve 5, during use, struts first support bar 1 and second support bar 2; Because locating part 6 one sides are not provided with countercheck rod 7; Described projection piece 8 can rotate to the rotatable sides of locating part 6, so rotating shaft 3 can rotate in axle sleeve 4, when forwarding certain angle to and place ladder; Because a side of locating part 6 is provided with the countercheck rod 7 that can prevent locating part 6 rotations; Described locating part 6 can not rotate to opposite side, and under the barrier effect of locating part 6, projection piece 8 can prevent to rotate in the opposite direction; First support bar 1 and second support bar 2 that promptly are fixedly connected on rotating shaft 3 and the axle sleeve 4 can be limited in certain angle; Increased the stability and the safety of ladder, after using up, the end that stops of rotation adjusting axle sleeve 5 described countercheck rods 7 breaks away from locating part 6 under the effect of jointed shaft; Stop that no longer locating part 6 rotates to opposite side; At this moment rotating shaft 3 again, rotating shaft 3 just can be along reverse rotations, two support bars are closed up keep well.
The external surface of described axle sleeve 4 also is provided with groove, and the outside of described adjusting axle sleeve 5 is provided with an end and passes and regulate axle sleeve 5 and be inserted to the pick-and-place components 9 in the groove, prevents to regulate axle sleeve 5 rotations, further increases the stability and the safety of ladder.
