The gap of the position of 2 gag lever post of fixed transition seat 24 is provided between individual locating rod 53.
The single ladder 6 of the first of this Multipurpose ladder is identical with second single terraced 7 structures, and first single ladder 6 includes two first vertical rods
The first stepped stems of 61 and Duo Gen 62, more first stepped stems 62 are distributed between two the first vertical rods 61, second single ladder 7
Including two second vertical rods 71 and the second stepped stems of Duo Gen 72, more second stepped stems 72 are distributed in two the second vertical rods 71
Between.
The end of one the first vertical rod 61 and the end of corresponding second vertical rod 71 are respectively welded rotating disk 8, two rotating disks 8 it
Between be welded on by hinge, the end of another the first vertical rod 61 on the outer shroud end face of angle adjusting mechanism, another
The end of two vertical rods 71 and the transition seat end face of angle adjusting mechanism are welded, the rotation of the bearing pin and angle adjusting mechanism of rotating disk 8
Axis is on the same line.
The method phase plane of the above-mentioned end face of the first vertical rod of hinged place 61 and the length direction of the first vertical rod 61 has 2.5 ° of inclination angle,
Similarly the method phase plane of the above-mentioned end face of the second vertical rod of hinged place 71 and the length direction of the second vertical rod 71 also has 2.5 ° of inclination angle.
When this Multipurpose ladder serves as double ladder in use, first work angle governor motion：Outer shroud 5 and transition seat 2 is right
It should be respectively welded with first single 6 and second single ladder 7 of ladder, the gag lever post 24 of transition seat 2 departs from the locating rod 53 of outer shroud 5, by spoon plate 13
Stirring in groove 12a for column spinner 12 is stretched into, when groove 12a bottoms are stirred in the insertion of spoon plate 13, the pole 34 of spoon plate 13 and friction component
Ends contact, pole 34 then drive depression bar 32 to overcome the elastic force of spring 33 to move, friction plate 31 and the transition seat 2 of the end of depression bar 32
The bottom cell wall of mounting groove 21 depart from, rotating spoon plate 13 drives column spinner 12 to rotate, and three connecting rods 15 drive three latches respectively
The 14 side direction movements into column spinner 12, until latch 14 departs from the slot 51 of outer shroud 5, then make transition seat 2 and lock plate 1 overall
Rotated relative to outer shroud 5, until first single 6 and second single ladder 7 of ladder turns to predetermined position, again by the gag lever post of transition seat 2
24 turn between corresponding two locating rods 53, and now, angle adjusting mechanism is in shaping modes.
Then relatively rotate first single 6 and second single ladder 7 of ladder, angle is in sharp between first single 6 and second single ladder 7 of ladder
Angle, the size of angle can be adjusted according to required high flexible, and the first vertical rod 61 is away from the first vertical rod 61 and the second vertical rod 71
The end of be hinged side is contacted to earth, and the end that the second vertical rod 71 is hinged side away from the first vertical rod 61 with the second vertical rod 71 is also contacted to earth.
Work angle governor motion again：Rotating backward spoon plate 13 drives column spinner 12 to rotate, and three connecting rods 15 drive respectively
Three latches 14 are moved to the lateral direction of column spinner 12, and latch 14 is finally stretched into the corresponding slot 51 of outer shroud 5, complete angle
The angle control of governor motion, now, angle adjusting mechanism is in fixed mode.
Finally, after angle fixes between first single 6 and second single ladder 7 of ladder, first stepped stem 62 at first single middle part of ladder 6
Fixed between second stepped stem 72 at corresponding second single middle part of ladder 7 by fixing band 9.
When this Multipurpose ladder serves as long ladder in use, first adjusting angle adjusting mechanism to shaping modes, regulative mode
It is identical with the above-mentioned regulative mode served as when double ladder uses, remove fixing band 9.
Then, first single 6 and second single ladder 7 of ladder relatively rotates, and can be turned to amplitude peak, and first single ladder 6 and second is single
Angle a is 175 ° between ladder 7, the end face of the first vertical rod 61 of first single ladder 6 and second single terraced 7 corresponding end faces of second vertical rod 71
Contact.
Finally, angle adjusting mechanism is adjusted to fixed mode, it is not necessary to pass through first single ladder 6 of the connection of fixing band 9 and the
Two single ladders 7.
Now the first of this Multipurpose ladder single 6 and second single ladder 7 of ladder forms a long ladder.
In addition, outer shroud can be designed under the outer shroud of top half and half of upper and lower arrangement by angle adjusting mechanism in volume production
Portion's outer shroud, top outer shroud and bottom outer shroud, which are combined, collectively forms circumferential limited impression and 18 slots, top outer shroud
It is welded and fixed again after being combined with bottom outer shroud outside transition seat；Similarly, the disk body of lock plate and column spinner can also be divided into
Upper and lower two halfbody structures are formed.
Above-described is only one embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, under the premise without departing from the principles of the invention, some variations and modifications can also be made, these also should be regarded as belonging to this hair
Bright protection domain.
