Description

A kind of overturning-preventing vertical ladder
Technical field
This utility model belongs to ladder field, more specifically to a kind of overturning-preventing vertical ladder.
Background technology
The instrument that vertical ladder is lived for people or construction site is commonly used, it generally includes two vertical support bars, and two are propped up It is provided with some horizontal pedals, people move up on pedal by stepping down between strut.When using, two support bars Bottom supports on the ground, and the top of support bar leans against on metope or other objects, makes vertical ladder become certain angle of inclination.
But the defect that existing vertical ladder presence is easily toppled over:When people moves on vertical ladder, because position of centre of gravity changes, directly Ladder may be toppled over to deviating from metope side, and the people so on vertical ladder will fall, quite dangerous.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of overturning-preventing vertical ladder with balance weight.
For achieving the above object, this utility model provides following technical scheme:A kind of overturning-preventing vertical ladder, including vertical ladder originally Body, described vertical ladder body is provided with connecting rod, and described connecting rod is connected with vertical ladder body one-directional rotation, and described interlinking lever end is connected with flat Weighing apparatus block.
By adopting technique scheme, on vertical ladder body, the connecting rod of setting can be with respect to vertical ladder body one-directional rotation, this When setting up overturning-preventing vertical ladder, bottom forms a shaped as frame and supports sample, and lifting surface area increases, and frictional force increases, and can effectively drop The risk of low vertical ladder landing;The balance weight of interlinking lever end setting increases overturning-preventing vertical ladder to the resistance deviating from metope lopsidedness Power, effectively prevents overturning-preventing vertical ladder from toppling over to deviating from metope side.
Further, it is provided with ratchet mechanism between described connecting rod and described vertical ladder body.
By adopting technique scheme, connecting rod is connected by ratchet mechanism with the one-directional rotation of vertical ladder body:Structure letter Single, easily manufactured, motion is reliable, and the corner of ratchet can be adjusted as needed, thus convenient adjust connecting rod position, To adapt to the overturning-preventing vertical ladder of differing tilt angles placement.
Further, described vertical ladder body includes Telescopic positioning device, and described connecting rod includes Multi-section telescopic rod, arbitrary neighborhood It is slidably connected and is provided with the alignment pin of positioning between two expansion links.
By adopting technique scheme, overturning-preventing vertical ladder can stretch according to actual needs, and connecting rod can also root According to the telescopic length of overturning-preventing vertical ladder and use alignment pin stationary positioned, overturning-preventing vertical ladder thus can be adjusted to deviating from metope one Roll the length of oblique resistance arm so that overturning-preventing vertical ladder after tilting overall center of gravity near metope away from overturning-preventing vertical ladder Bottom fulcrum, so that overturning-preventing vertical ladder is set up more stable, reduce overturning-preventing vertical ladder to deviating from the wind that metope side is toppled over Danger, thus reduce the risk that people drops from overturning-preventing vertical ladder.
Further, described balance weight is connected with link detachable.
By adopting technique scheme, balance weight can be pulled down from connecting rod, thus can facilitate overturning-preventing vertical ladder Move before use and after using, be convenient to mount and dismount, simple and reliable, facilitate people to move overturning-preventing vertical ladder.
Further, described interlinking lever end is removably connected with grafter.
By adopting technique scheme, if people leaves behind the balance weight supporting with overturning-preventing vertical ladder, can be by body The weight on side is pressed on grafter, so almost equivalent with balance weight, gathers materials on the spot, and improves efficiency, reduces cost.
Further, described vertical ladder body is provided with the groove that can accommodate connecting rod.
By adopting technique scheme, after balance weight and grafter being pulled down from connecting rod, by connecting rod precession vertical ladder In groove on body, the outside of such overturning-preventing vertical ladder is flatter, and will not scratch article or human body are it is possible to protection people Body.
Further, described vertical ladder body lower end is provided with support plate, and described support plate is arranged at vertical ladder body and deviates from metope side, The lower end of described support plate and described vertical ladder body is hinged and is provided with torsion spring between support plate and vertical ladder body.
There is provided the pressure towards wall by adopting technique scheme, support plate and torsion spring for vertical ladder body, so permissible Reduce overturning-preventing vertical ladder to deviating from the risk that metope side is toppled over, thus protecting the safety of people.
In sum, on vertical ladder body, the connecting rod of setting so can set up anti-dumping with respect to vertical ladder body one-directional rotation The when of falling vertical ladder, bottom forms a shaped as frame and supports, and lifting surface area increases, and frictional force increases, and can effectively reduce vertical ladder landing Risk;The balance weight of interlinking lever end setting increases overturning-preventing vertical ladder to the resistance deviating from metope lopsidedness, effectively prevents Topple over vertical ladder and topple over to deviating from metope side;Vertical ladder body and connecting rod all can stretch, and thus can adjust overturning-preventing vertical ladder To the length of the resistance arm deviating from metope lopsidedness so that overturning-preventing vertical ladder overall center of gravity is remote near metope after tilting From the bottom fulcrum of overturning-preventing vertical ladder, so that overturning-preventing vertical ladder is set up more stable, reduce overturning-preventing vertical ladder to deviating from metope The risk that side is toppled over, thus reduce the risk that people drops from overturning-preventing vertical ladder;Balance weight and grafter all can be from connecting rods Pull down, sample just can facilitate overturning-preventing vertical ladder before use and move after using, and be convenient to mount and dismount, simple and reliable, facilitate people Move overturning-preventing vertical ladder;Generally play the purpose preventing toppling over and protect the safety of people.
