Abstract
A portable ladder comprises two sets of telescopic supporting assemblies and pedals connecting the two sets of supporting assemblies together, and the two sets of supporting assemblies are parallelly arranged. Each set of supporting assemblies is formed by pivoting a plurality of connecting rods in an end-to-end mode, and first pivoting parts of the connecting rods are arranged at the end-to-end pivoting positions. In the two sets of supporting assemblies, the connecting rods at the corresponding positions are pivoted at the middle positions, and second pivoting parts of the connecting rods are arranged at the middle pivoting positions; and the connecting rods are different in length specification, so that the two sets of supporting assemblies form a telescopic and expandable mechanism. In the two sets of parallelly arranged supporting assemblies, the first pivoting parts at the corresponding positions are connected with the two ends of the corresponding pedals, and the second pivoting parts at the corresponding positions are connected with the two ends of the corresponding pedals. The portable ladder is good is rigidity and strength and high in using safety.
Description
Technical field
The present invention relates to scissor mechanism field, more particularly, to a kind of portable ladder.
Background technology
Scissor mechanism has at present and is widely applied very much and develops, such as folding tent, contractile door curtain,
Elevator, foldable desk lamp or mechanical arm etc..Its feature is that magnification is big, extensible distance and big
Span, and work as taken up space very little after it shrinks, therefore it is applied in many industries.
The scissors machine of one side scissor mechanism or double parallel is used at present in the application of most of scissor mechanism
Structure, such as door curtain uses one side scissor mechanism, and elevator uses the scissor mechanism of double parallel.Mostly
The major defect of the scissor mechanism of number is the intensity of the structure on its Impact direction under being acted on by multi-direction power
It is not enough to bear the load-bearing effect of this power with rigidity, be susceptible to askew folding, safety is not also high.Additionally, passing
The scissor mechanism of system is all straight line moving, can only realize moving back and forth in both direction, using the current political situation
Sex-limited too big.
Content of the invention
It is an object of the invention to proposing a kind of portable ladder, launch during use, convenient and swift；No
Draw in during use, save space, and there is good rigid, intensity, use safe.
For reaching this purpose, the present invention employs the following technical solutions：
A kind of portable ladder；Including two groups of telescopic support components with by two groups of sustainable assemblies even
The pedal being connected together, support component described in two groups be arranged in parallel；
Every group of support component is formed by some connecting rod head and the tail pivot joints, and this head and the tail pivot points is described connection
First articulated section of bar；In support component described in two groups, the corresponding described connecting rod in position is in medium position phase
Mutually pivot joint, in the middle part of this, pivot points are the second articulated section of described connecting rod；In support component described in two groups
The length specification of described connecting rod is unequal, and support component described in two groups is formed a set of telescopic with this
Described development agency；
The support component described in two groups be arrangeding in parallel, corresponding described first articulated section in position is stepped on described respectively
The two ends of pedal connect；Corresponding described second articulated section in position is connected with the two ends of described pedal respectively.
Further, it is provided with movable buckle by the described pedal of corresponding for link position described second articulated section
It is fastened togather.
Further, in the support component described in two groups be arrangeding in parallel, the two ends of described pedal are fixedly installed
In described first articulated section being in inner side.
Further, described pedal is straight panel part.
Further, described plate surface of trampling is provided with anti-sliding rib.
Beneficial effects of the present invention：Form the support component described in two groups of described support component, used is described
The length specification of connecting rod differs, and one of which support component is fixed perpendicular to the ground, then drives ladder to beat
When opening, another group of support component is opened along the direction favouring ground, each pedal is supported into and is tilted towards
On form, in support component described in two groups, with the increase at θ angle, the overall angle of inclination of mechanism also with
Increase, adapt to the use of different occasions.
Brief description
Fig. 1 is the structural representation of one embodiment of the present of invention；
Fig. 2 is the side view of one embodiment of the present of invention；
Fig. 3 is the top view of one embodiment of the present of invention；
Fig. 4 is the structural representation of support component unit in the present invention.
Wherein：Support component 1, pedal 2, connecting rod 3, the first articulated section 4, the second articulated section 5, live
Dynamic buckle 6.
Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
As shown in Figures 1 and 2, a kind of portable ladder；Including two groups of telescopic support components 1
With the pedal 2 that two groups of sustainable assemblies link together, described in two groups, support component 1 be arranged in parallel；
As shown in figure 3, every group of support component 1 is formed by some connecting rod 3 head and the tail pivot joints, this head and the tail pivot
Connect the first articulated section 4 that position is described connecting rod 3；In support component 1 described in two groups, the corresponding institute in position
State connecting rod 3 in the mutual pivot joint of medium position, in the middle part of this, pivot points are the second pivot joint of described connecting rod 3
Portion 5；In support component 1 described in two groups, the length specification of described connecting rod 3 is unequal, supports described in two groups
Assembly 1 forms a set of telescopic deployable structure with this；
The support component 1 described in two groups be arrangeding in parallel, corresponding described first articulated section 4 in position respectively with described
The two ends of pedal 2 connect；Corresponding described second articulated section 5 in position respectively with described pedal 2 two
End connects.
Form the support component described in two groups of described support component 1, the length of the described connecting rod 3 being used
Specification differs, when one of which support component 1 being fixed perpendicular to the ground, then driving ladder to open, another
Group support component 1 is opened along the direction favouring ground, and each pedal 2 is supported into the shape tilting upward
State, as shown in figure 4, in support component described in two groups, with the increase at θ angle, the overall inclination angle of mechanism
Degree also and then increases, and adapts to the use of different occasions；When not using, deposit after two groups of support components 1 are shunk
Put or carry, convenient and reliable.
It is provided with movable buckle 6 to engage the described pedal 2 of corresponding for link position described second articulated section 5
Together, by the described pedal 2 of the second articulated section 5 of movable buckle 6 correspondence position, improve mechanism
Stability.
In the support component 1 described in two groups be arrangeding in parallel, the two ends of described pedal 2 are fixedly installed on and are in
Described first articulated section 4 of inner side, connects the described pedal 2 of the first articulated section 4, two ends are to be fixedly connected
, rather than roll, it is to avoid cause danger during using mechanism.
