Description
Technical Field
The utility model relates to a ladder is rolled over in two side scrambles.
Background
Ladder that two side climbing folding ladder both sides all can climb is symmetrical structure generally, divides preceding ladder frame and back ladder frame, and the top is the tie point and the rotation axis that opens and shuts to use even piece restriction angle that opens and shuts.
Generally, the double-side climbing folding ladder is simple in structure, key structural parts are front and rear frame connecting points and connecting pieces, the key points for achieving folding and using safety and stability of the ladder are that the ladder is easy to fold automatically and contact with earth unevenly in the using process.
For example: the structure that current two side climbing ladder front, back ladder frame are mostly the line connection, in footboard section bar in top one side can insert opposite side footboard section bar promptly, adopt self-tapping screw to fix in order preventing to scatter to form a pivot, lead to the ladder to touch to earth unevenly four feet in the use.
Moreover, the front ladder frame and the rear ladder frame of the existing double-side climbing ladder are not completely the same, and the front ladder frame and the rear ladder frame can be effectively opened and closed by the connection of two different top pedals at the top, so that the ladder frames need to be divided into a front ladder frame and a rear ladder frame, plastic parts are needed for decorating the top, and the cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a reach to earth effectually, stand steady two side climbing folding ladder.
The purpose of the utility model is realized like this:
the utility model provides a ladder is rolled over in two side scrambles, includes preceding ladder frame, back ladder frame and takes self-locking function's even piece subassembly, the left and right both sides in top of preceding ladder frame are provided with preceding connection piece respectively, and the left and right both sides in top of back ladder frame are provided with the back connection piece respectively, preceding connection piece and back connection piece pass through first connecting piece and connect, and preceding connection piece and back connection piece all use first connecting piece to rotate as rotation center, expand each other or draw close each other between realization preceding ladder frame and the back ladder frame, even preceding ladder frame is connected to piece subassembly one end, even the back ladder frame is connected to the piece subassembly other end, even the expansion angle of ladder frame and back ladder frame before the piece subassembly restriction.
Preceding connection piece and back connection piece are connected through first connecting piece, through point connection between ladder frame and the back ladder frame before realizing, so that only produce two tie points between preceding ladder frame and the back ladder frame, such connected mode can make preceding ladder frame and back ladder frame have certain torsional capability, even the ladder has unevenness slightly with ground contact, the ladder also can produce the wrench movement in certain extent, thereby contact ground steadily and stand, can make two side climbing folding ladder carry out the self-adaptation to the condition of unevenness on ground like this, increase preceding ladder frame, back ladder frame and ground contact effect, make two side climbing folding ladder stand more steadily, and through the elasticity degree of adjusting preceding connection piece and back connection piece connection, can adjust the adaptation degree of ladder to ground, improve the application scope of ladder.
The purpose of the utility model can also adopt the following technical measures to solve:
further, even piece subassembly includes even piece and back even piece before even, preceding even piece is with the preceding ladder frame of rotation mode connection, preceding even piece up end is provided with first baffle, the back is even the piece and is connected the back ladder frame with the rotation mode, back even piece up end is provided with the second baffle, even piece and preceding even piece part overlap after, and even piece and preceding even piece overlap the department and connect through the second connecting piece, and the second baffle is located first baffle below, and preceding even piece and back are even rotatory as the rotation center with the second connecting piece, and the direction of rotation of even piece after first baffle restriction, the direction of rotation of even piece before the second baffle restriction.
When the ladder used, even piece subassembly expandes, because even piece subassembly expandes the back and is not straight state, consequently produce certain angle, lead to even piece and back even piece junction to appear sinking before leading to, when the ladder received the resultant force again, even piece and back even piece can appear the power of closing in down, but the restriction of first baffle and second baffle, even piece and back even piece can't be closed in the below before, consequently the ladder will be unable from closing in, only after finishing using, manual even piece and back even piece are upwards closed in the front, just can restore the ladder and draw close the state each other (fold condition promptly).
Furthermore, foot sleeves with large ground contact areas are arranged at the bottoms of the front ladder frame and the rear ladder frame. Through being provided with the podotheca that area is big to ground, make ladder and ground area of contact bigger to make the ladder can stand steadily, improve the practicality of two sides climbing folding ladder greatly.
Further, the first connecting piece and the second connecting piece are both rivets.
The beneficial effects of the utility model are as follows:
the utility model discloses, preceding connection piece and back connection piece are connected through first connecting piece, through point connection between ladder frame and the back ladder frame before realizing, so that only produce two tie points between preceding ladder frame and the back ladder frame, such connected mode can make preceding ladder frame and back ladder frame have certain torsional capacity, even the ladder contacts unevenness slightly with ground, the ladder also can produce the wrench movement in the certain limit, thereby contact ground steadily and stand, can make two side climbing folding ladder carry out the self-adaptation to the uneven condition in ground like this, ladder frame before increasing, back ladder frame and ground contact effect, it is more steady to make two side climbing folding ladder stand, and the elasticity degree of connecting piece and back connection piece connection before adjusting, can adjust the adaptation degree of ladder to ground, improve the application scope of ladder.
The utility model discloses, when the ladder used, even piece subassembly expandes, because even piece subassembly expandes the back is not straight state, consequently produce certain angle, it is sunken to lead to even piece and back even piece junction to appear before leading to, when the ladder receives the resultant force again, the power of closing downwards can appear even piece and back even piece before even, but the restriction of first baffle and second baffle, even piece and back even piece can't be closed downwards before, consequently the ladder will be unable from closing, only when finishing using the back, manual even piece and back even piece are upwards closed before will, just can restore the ladder and draw close the state each other (fold condition promptly).
The utility model discloses, through being provided with the podotheca that area is big to ground, make ladder and ground area of contact bigger to make the ladder can stand steadily, improve the practicality that two side scrambles the book ladder greatly.
