Kind application method, the first is that electromagnet 24 is powered, and electromagnet 24 attracts slide bar 22, slide bar 22 to drive pin B past separate hollow
The direction of casing 7 is moved, and spring B 25 stretches, and all hollow sleeves 7 are extracted out, and electromagnet 24 powers off, and electromagnet 24 is to cunning
The attraction of bar 22 disappears, and is driven in the elastic force of spring B 25, pin B 27 is moved toward 7 direction of hollow sleeve, pin B's 27
Head passes through three through-holes, blocks hollow sleeve 7, realizes locking, you can it is to need to make to use extension ladder, second of application method
When with extension ladder, hollow sleeve 7 is pulled, when the through-hole of 7 upper end of hollow sleeve and the upper section hollow sleeve of the section hollow sleeve 7
After the through-hole alignment of 7 lower ends, the head of pin B 27 is squeezed under the action of spring B 25 in through-hole, and through-hole is blocked, and is realized
Locking, you can use.When needing to pack up extension ladder, electromagnet 24 is powered, and electromagnet 24 attracts slide bar 22, slide bar 22 to drive pin
B 27 is followed closely toward the direction movement far from hollow sleeve 7, pin B 27 is exited from the through-hole of 7 lower end of hollow sleeve, and hollow sleeve 7 is
It can pack up successively, you can keep extension ladder well.
Embodiment 6
As shown in fig. 6, the present embodiment is further improved on the basis of embodiment 1, it is specially further, described
Locking assembly includes the pin C 28 being horizontally placed on inside transverse supporting rod 1, and 7 top and bottom of the hollow sleeve offer
The through-hole that 28 heads pin C may pass through, the through hole that the interconnecting piece 2 corresponds to 7 upper end of hollow sleeve also offer pin C 28
The through-hole that head may pass through, when 7 lower end of a upper section hollow sleeve of the through-hole and section hollow sleeve 7 of 7 upper end of hollow sleeve
After through-hole alignment, the head of pin C 28 can be sequentially passed through from the through-hole of interconnecting piece 27 upper end of hollow sleeve through-hole and
The through-hole of 7 lower end of a upper section hollow sleeve of the section hollow sleeve 7 realizes that locking, the setting of 1 lower end of the transverse supporting rod are limited
Position slot B 29,28 tail portions pin C be provided with can in limiting slot B 29 movable poke rod B 30, the transverse supporting rod 1
Interior middle part is provided with partition board 32, and spring C 31 is provided between the partition board 32 and poke rod B 30, specifically, there are two types of use
Method, the first is to use hand-motion poke rod B 30, drives pin C toward the direction movement far from hollow sleeve 7, and spring C 31 is pressed
Contracting, extracts all hollow sleeves 7 out, decontrols poke rod B 30, and in the case where the elastic force of spring C 31 drives, pin B is toward hollow sleeve
7 direction of pipe moves, and the head of pin C 28 passes through three through-holes, blocks hollow sleeve 7, realizes locking, you can extension ladder is used,
Second of application method is when needing using extension ladder, to pull hollow sleeve 7, when in the through-hole and the section of 7 upper end of hollow sleeve
After the through-hole alignment of 7 lower end of a upper section hollow sleeve of empty set pipe 7, the head of pin C 28 is under the action of spring C 31
It squeezes into through-hole, blocks through-hole, realize locking, you can use.When needing to pack up extension ladder, with hand-motion poke rod B 30, band
Dynamic pin C is compressed toward the direction movement far from hollow sleeve 7, spring C 31, and pin C 28 is moved back from the through-hole of 7 lower end of hollow sleeve
Go out, hollow sleeve 7 can be packed up successively, you can keep extension ladder well.
