Lock, for the transverse bar to be locked in the stowed position.
Although cat ladder disclosed in the patent uses simply, cat ladder movement is inconvenient, and can not be by cat ladder when use
Ontology effective position is lived, inconvenient for operation, and therefore, it is necessary to design a kind of ladder.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of ladder, the ladder have behaviour
Make convenient feature.
Object of the invention can be realized by the following technical scheme：Ladder, including cat ladder ontology, which is characterized in that institute
It states cat ladder body lower part and idler wheel is provided with by connection structure, connection structure includes mounting plate, positioning plate, guide rod, guide sleeve and bullet
Spring, mounting plate are fixed on cat ladder body lower part, and guide rod is fixed on a mounting board vertically, and guide sleeve is slidably arranged on guide rod, spring
It is threaded through on guide rod, spring upper end is connected with mounting plate, and lower spring end is connected with guide sleeve, and positioning plate is fixed on guide sleeve, idler wheel
It is fixed on positioning plate；It is additionally provided with location structure on the cat ladder ontology.
Working principle of the present invention is as follows：Supermarket staff needs to above shelf to arrange cargo, and cat ladder ontology is led to
The idler wheel for crossing lower part pushes under shelf, is then positioned cat ladder ontology by the effect of location structure, proceed with one's work personnel
Cat ladder ontology can be climbed up and arrange shelf, when needs move to another place arrangement, the effect of location structure is released, then pass through idler wheel
Mobile cat ladder ontology changes to different places, easy to operate.
As the first situation, the location structure includes motor, the first connecting rope, the first weight and the first auxiliary
Wheel, motor are fixed on cat ladder body lower part, and the output shaft of motor is horizontally disposed, the output shaft end of motor and the first connecting rope one
End is connected, and the first connecting rope other end and the first weight are connected, and the first auxiliary wheel is arranged on the first weight.
