Specific implementation mode
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art without making creative work, the every other reality obtained
Example is applied, the scope of the present invention is belonged to.
Attached drawing 1 is the folding state of the present invention, and attached drawing 2 is the unfolded state of the present invention;The process that the present invention is unfolded is as follows:
Descending stair leg 1 is pulled out, descending stair is separated around the upper ladder of connection with the hinge rotation of descending stair, with upper ladder, passes through gravity
Or manual foot of ladder plate 51 makes foot of ladder plate 51 drive with the hinge rotation of terraced leg 1, foot of ladder plate 51 around connection foot of ladder plate 51 to be mounted on ladder
Connecting rod 52 on sole 51 moves down, connecting rod 52 drives the guide hole along guide block 54 of lock tongue 53 to move down, be rotated further foot of ladder plate 51 until
1 madial wall of the arrival descending stair of connecting rod 52 leg, lock tongue is entirely retracted in guide block 54 at this time, is rotated further descending stair, 62 outside inclined-planes of hook
With 1 upper-end contact of descending stair leg, further hook 62 overcomes the effect of elastomer 63 to step into the mouth of hook of descending stair 1, in bullet
The mouth of hook top of descending stair 1 is hooked under the action of property body 63;
Foot of ladder plate 51 is toward back rotation, and the connecting rod 52 on foot of ladder plate 51 moves up, connecting rod 52 drives lock tongue 53 to be led along guide block 54
Hole moves up, and is rotated further in the hole of foot of ladder plate 51, the entrance hook of lock tongue 53 seat 61, at this point, lock tongue 53 is matched with guide block 54 and hook seat 61
It closes, ladder, descending stair is made to be maintained at same plane, meanwhile, 53 side wall of lock tongue limits 62 movement of hook, and ensure that will not break off relations,
Improve safety;
Both sides ladder is separated outward, be separately fixed at two end caps 3 of ladder upper end around interconnection hinge rotation,
Double ladder is formed, frame 4 will be drawn to open, is overlapped, since 43 height of end carriage is beyond frame 4 liang of side planes are drawn, drawing frame 4 above
End carriage 43 and lower part draw the end carriage 43 of frame 4 to hook another crossbeam 42 for drawing frame 4 respectively, in this way, forming stable double ladder;
When needing to adjust ladder opening angle, is coordinated by adjusting end carriage 43 and the crossbeam 42 of different location, be may be implemented
Adjust ladder subtended angle function.
The process of the folding present invention is as follows:
Rotation foot of ladder plate 51 drives connecting rod 52, the guide hole along guide block 54 of lock tongue 53 to move down, be rotated further foot of ladder plate 51 until
1 madial wall of the arrival descending stair of connecting rod 52 leg, lock tongue is entirely retracted in guide block 54 at this time, hook 62 is unlocked, by lower draw-bar 62
Pinning, pinning compresses elastomeric 63 simultaneously make the inside rotation of hook 62 further diverge from descending stair leg 1, and rotation descending stair leg 1 closes ladder again
Sole 51, until complete folding.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention;
Various modifications to these embodiments will be apparent to those skilled in the art, defined in the present invention
General Principle can not depart from the present invention spirit or scope in the case of, realize in other embodiments.Therefore, originally
Invention will not be defined to the embodiments shown herein, and be to fit to and the principles and novel features disclosed herein
Consistent widest range.
