Description of the drawings
Fig. 1 is the structural schematic diagram of Portable ladder open shape of the present invention.
Fig. 2 is the structural schematic diagram of ascending pedal column 4 in Fig. 1.
Specific implementation mode
The specific embodiment of Portable ladder of the present invention, as shown in Figure 1, Portable ladder, by steel hollow form
Hollow cuboid mobile jib 1, the stabiliser bar of 1 upper and lower ends of mobile jib connection and suit are connected to 4 groups of the pedal rod on the mobile jib body of rod 1
At;Mobile jib 1 is that the master of Portable ladder ascends a height bar, is the hollow cuboid mobile jib of steel hollow form, and 1 upper and lower ends of mobile jib connect
It is connected to and keeps the stabiliser bar that will not turn on one's side of mobile jib 1, stabiliser bar is divided into stabiliser bar 3 and lower stabiliser bar 2, upper stabiliser bar 3 and lower steady
2 structure of fixed pole is the same, upper stabiliser bar 3, and the both sides of 1 upper end of mobile jib, upper stable bar side are connected to by hinge-type junction button 32
While being provided with the movable button 31 of connection support column 33, upper stabiliser bar outer end is provided with stabilizer foot;Lower stabiliser bar 2 is connected with mobile jib
Method is as 3 connection method of upper stabiliser bar;As shown in Fig. 2, ascending pedal bar 4, is divided into left and right two, 41 Hes are detained by lifting
43 two parts of pedal cross bar form, and lifting button 41 is rectangular hollow frame, and shape and mobile jib cross-sectional shape correspond to, rectangle
Framework and pedal cross bar 43 on the outside of hollow frame a side connect, and rubber is provided in the framework on the inside of rectangular hollow frame both ends
Interior bite-block 42, inside casing size are advisable with can easily be sleeved on the mobile jib body of rod;Pedal cross bar 43, inner end are connected to lifting button
On 41 outer side frame bodies, outer end is provided with hollow form pedal nest, and hollow form pedal nest bottom is foot pedal, on hollow form pedal nest
Portion is adjustable card base band.
It is in the Portable ladder of open shape by upper and lower stabiliser bar first during Portable ladder use of the present invention
Lower stabiliser bar be placed on the ground at the wall that needs to ascend a height, then upper stabiliser bar is rested on to the upper of wall that need to ascend a height
Side, because lower stabiliser bar, upper stabiliser bar outer end are both provided with stabilizer foot, on ascending a height by wall plus step ladder, step ladder is all
It can reserve certain gradient, on the wall for leaning against the place that needs to ascend a height that Portable ladder can be stablized under this state, mobile jib
The ascending pedal bar being set on the body of rod, but because lifting is detained is provided with bite-block in rubber in the framework on the inside of both ends, in addition ascending a height
The weight of pedal cross bar will overweight lifting button in pedal rod, so even if under static state, ascending pedal bar is in its pedal cross
Ensure that it can detain in framework on the inside of both ends in the rubber that is arranged bite-block due to pedal cross by lifting under the pressure effect of bar
Bar breaks lifting button internal balance during moving downward, cause to be provided in rubber in the framework on the inside of the inside and outside end of lifting button
Bite-block forms the action for pushing away, squeezing to the Portable ladder mobile jib body of rod simultaneously, ensures that the lifting button of ascending pedal bar in this way
It can easily be buckled on the mobile jib body of rod.When needing to ascend a height, the left and right foot distribution of mountaineer is stepped in left and right pedal cross bar outer end is arranged
On the foot pedal of empty shape pedal nest, then the adjustable card base band on fastening hollow form pedal nest top is alternately controlled by both feet and is stepped on
The balance of high pedal rod, upward foot-up when ascending pedal bar is controlled to balance, at this point, the framework on the inside of inside and outside end is detained in lifting
Bite-block does not form the mobile jib body of rod action for pushing away, squeezing in upper rubber, so ascending pedal bar can be easily along sliding on the mobile jib body of rod
Row, when foot jams on action to the formation of ascending pedal club shaft, lifting button internal balance is broken, and lifting is detained on the inside of inside and outside end
Framework in rubber bite-block the action for pushing away, squeezing is re-formed to the mobile jib body of rod, the lifting button of ascending pedal bar is buckled in master again
On club shaft, both feet operate successively, you can achieve the purpose that ascend a height.When mountaineer's downlink, is alternately controlled and ascended a height by both feet
The balance of pedal rod stretches downwards foot-up when ascending pedal bar is controlled to balance, at this point, the framework on the inside of inside and outside end is detained in lifting
Bite-block does not form the mobile jib body of rod action for pushing away, squeezing in upper rubber, so ascending pedal bar can glide along the mobile jib body of rod easily
Row, the desired location slided, foot, which makes ascending pedal club shaft, jams on action, and lifting button internal balance is broken, lifting button
Bite-block re-forms the mobile jib body of rod on the action for pushing away, squeezing, the lifting button of ascending pedal bar in rubber in framework on the inside of inside and outside end
It is buckled in again on the mobile jib body of rod, both feet operate successively, you can achieve the purpose that downlink.After Portable ladder use, beat
The movable button of the connection support column of upper and lower stabiliser bar side setting is opened, the hinge-type junction button of upper and lower stabiliser bar connection mobile jib closes
It closes, upper and lower stabiliser bar and mobile jib is finally made to reach closed state.
