The ladder main part includes left pole setting and right pole setting, sets up a plurality of pedals between left pole setting and the right pole setting, be provided with at least one supporting mechanism in the ladder main part, supporting mechanism is including being fixed in the fixed staple bolt in left pole setting and the right pole setting and being fixed in the mounting of pedal below, be provided with the bracing piece between fixed staple bolt and the mounting. The utility model relates to a supporting mechanism on extension ladder, supporting mechanism sets up between the pole setting and the pedal of ladder, it is fixed to form the triangle through supporting mechanism, make the overall structure of ladder more stable, it is littleer to rock, especially on extension ladder, because extension ladder's structure comprises the pole setting that the multisection was established each other to overlap, certain clearance must exist between each pole setting, therefore, the ladder is when expanding the use, rock more easily, the last supporting mechanism that is equipped with of extension ladder, can promote the security performance of ladder greatly, reduce the potential safety hazard.
Description
Technical Field
The utility model belongs to the technical field of the ladder, refer in particular to a supporting mechanism of extension ladder.
Background
The ladder is people's daily life apparatus, people can use the ladder to take and put the thing at the eminence usually, the ladder is more the thing commonly used in fitment and building trade, the ladder of commonly used has many forms like straight ladder, extension ladder etc. but no matter which kind of ladder, because of its operational environment's particularity, the user all can regard the security very much when using, with the personal safety of guarantee oneself, the security of ladder, most main still the stability of ladder when using, whether can rock, therefore, the application provides a better ladder of stability.
Disclosure of Invention
The utility model aims at providing a simple structure, stability is good, is difficult for rocking, convenient to use's extension ladder's supporting mechanism.
The purpose of the utility model is realized like this:
the utility model provides a telescopic ladder's supporting mechanism, includes the ladder main part, and the ladder main part includes left pole setting and right pole setting, sets up a plurality of pedals between left pole setting and the right pole setting, be provided with at least one supporting mechanism in the ladder main part, supporting mechanism is including being fixed in the fixed staple bolt in left pole setting and the right pole setting and being fixed in the mounting of pedal below, be provided with the bracing piece between fixed staple bolt and the mounting.
The utility model discloses it is further, bracing piece first bracing piece of telescopic and second bracing piece respectively, first bracing piece one end articulates on fixed staple bolt, and the second bracing piece articulates on the mounting, and the other end of first bracing piece and second bracing piece is connected.
The utility model discloses it is further, first bracing piece and second bracing piece are the hollow tube, and first bracing piece and second bracing piece are overlapped mutually and are located and be in the same place.
The utility model discloses it is further, be provided with spacing marble between first bracing piece and the second bracing piece.
Compared with the prior art, the utility model outstanding and profitable technological effect is:
the utility model relates to a supporting mechanism on extension ladder, supporting mechanism sets up between the pole setting and the pedal of ladder, it is fixed to form the triangle through supporting mechanism, make the overall structure of ladder more stable, it is littleer to rock, especially on extension ladder, because extension ladder's structure comprises the pole setting that the multisection was established each other to overlap, certain clearance can exist necessarily between each pole setting, therefore, the ladder is when expandedly using, rock more easily, the last supporting mechanism that is equipped with of extension ladder, can promote the security performance of ladder greatly, reduce the potential safety hazard, especially when nobody helps holding up the ladder, the stability of ladder is especially important. The concrete structure has been including being fixed in the fixed staple bolt in left pole setting and the right pole setting and being fixed in the mounting of pedal below, be provided with the bracing piece between fixed staple bolt and the mounting. Through triangle-shaped stable in structure's principle, form a triangle-shaped with pole setting, pedal and bracing piece, let the ladder more firm.

Detailed Description
The invention will be further described with reference to specific embodiments below:
the utility model provides a telescopic ladder's supporting mechanism, includes the ladder main part, and the ladder main part includes left pole setting 1 and right pole setting 2, sets up a plurality of pedal 3 between left pole setting 1 and the right pole setting 2, be provided with at least one supporting mechanism in the ladder main part, supporting mechanism is including being fixed in fixed staple bolt 4 on left pole setting 1 and the right pole setting 2 and being fixed in the mounting 5 of pedal 3 below, be provided with bracing piece 6 between fixed staple bolt 4 and the mounting 5.
The utility model relates to a supporting mechanism on extension ladder, supporting mechanism sets up between the pole setting of ladder and pedal 3, it is fixed to form the triangle through supporting mechanism, make the overall structure of ladder more stable, it is littleer to rock, especially on extension ladder, because extension ladder's structure comprises the pole setting that the multisection was established each other to overlap, certain clearance can exist necessarily between each pole setting, therefore, the ladder is when expandedly using, rock more easily, the last supporting mechanism that is equipped with of extension ladder, can promote the security performance of ladder greatly, reduce the potential safety hazard, especially when nobody helps holding up the ladder, the stability of ladder is especially important. The concrete structure has included being fixed in fixed staple bolt 4 and being fixed in on left pole setting 1 and the right pole setting 2 and having been equipped with bracing piece 6 between fixed staple bolt 4 and the mounting 5 pedal 3 below. Through triangle-shaped stable in structure's principle, form a triangle-shaped with pole setting, pedal 3 and bracing piece 6, let the ladder more firm.
The utility model discloses an optimal scheme does, bracing piece 6 is the first bracing piece 7 of telescopic and second bracing piece 8 respectively, and 7 one ends of first bracing piece articulate on fixed staple bolt 4, and second bracing piece 8 articulates on mounting 5, and the other end of first bracing piece 7 and second bracing piece 8 is connected. The first supporting rod 7 and the second supporting rod 8 are hinged to the ladder, and the supporting rod 6 of the extension ladder can be folded quickly when the extension ladder is retracted, so that the supporting rod 6 is not required to be detached. Is convenient to use.
The utility model discloses an optimal scheme does, first bracing piece 7 and second bracing piece 8 are the hollow tube, and first bracing piece 7 and second bracing piece 8 are overlapped mutually and are located and are in the same place.
The utility model discloses an optimal scheme does, be provided with spacing marble 9 between first bracing piece 7 and the second bracing piece 8.
Two bracing pieces 6 are mutually sleeved and arranged, and a marble 9 is limited and limited between the two bracing pieces. When folding, only need press spacing spring, can make first bracing piece 7 and second bracing piece 8 slide each other.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
