Description
Technical Field
The utility model relates to a ladder technical field specifically is a comprehensive city is with safe portable ladder of using.
Background
A herringbone ladder is also called a folding ladder and is used for a type of climbing tools working in the space above a plane, when the herringbone ladder is used, front and back ladder rods and the ground form an isosceles triangle and look like a ' people ' character, so the herringbone ladder is called as a herringbone ladder ' vividly, because the herringbone structure can often lead the ladder to swing left and right, particularly the herringbone ladder with a higher gravity center is inclined upwards, people can easily lead the gravity centers at two sides of the ladder to be unstable and turn over when working on the ladder, and therefore one person or more people are needed to hold the ladder to ensure the stability of the ladder, which is inconvenient and dangerous for single use.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Not enough to prior art, the utility model provides a comprehensive city that is difficult for turning on one's side of safe in utilization is with safe portable ladder has solved the problem that proposes in the above-mentioned background art.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a comprehensive city is with safe portable ladder of using, includes two one end mutual articulated ladder bodies, and the middle part of two ladder bodies is equipped with mutual articulated first connecting rod and second connecting rod, set up the bar recess on the lateral wall of ladder body, the upper end of bar recess articulate have with bar recess complex bracing piece, limit bracing piece pivoted stop gear on the ladder body, the holding tank has been seted up to the one end of bracing piece, be equipped with the extension rod in the holding tank, a plurality of locating holes have been seted up on the extension rod, the screw hole has been seted up to the lower extreme of bracing piece, the spiro union has with locating hole complex fixing bolt in the screw hole.
Furthermore, the limiting mechanism is a limiting plate which is arranged at the upper end of the groove and extends downwards.
Furthermore, the limiting mechanism is a slope arranged at the upper end of the groove.
Furthermore, a mounting hole in threaded connection with the fixing bolt is formed in the groove.
Furthermore, both sides of each ladder body are provided with support rods.
(III) advantageous effects
To sum up, the utility model discloses must the ladder both sides have the holding power, form conical bearing structure to but the ladder can not control and rock, increases its safety in utilization, can draw in the bracing piece in bar groove portable and deposit when not.

Detailed Description
The embodiment of the portable ladder for safety in a comprehensive city according to the present invention will be further described with reference to fig. 1 to 3.
The utility model provides a comprehensive city is with safe portable ladder of using, includes two one end mutual articulated ladder bodies 1, and the middle part of two ladder bodies 1 is equipped with mutual articulated first connecting rod 8 and second connecting rod 9, bar recess 2 has been seted up on ladder body 1's the lateral wall, bar recess 2's upper end articulate have with bar recess 2 complex bracing piece 3, 3 pivoted stop gear of restriction bracing piece on the ladder body 1, the holding tank has been seted up to bracing piece 3's one end, be equipped with extension rod 4 in the holding tank, a plurality of locating holes 7 have been seted up on extension rod 4, threaded hole has been seted up to the lower extreme of bracing piece 3, threaded hole spiro union have with locating hole 7 complex fixing bolt 5.
When needs use the ladder, as long as place the ladder in suitable position, then outwards rotate bracing piece 3, until bracing piece 3 by spacing unable outwards rotation of stop gear, then unscrew fixing bolt 5, extract extension rod 4 that is located the holding tank, until extension rod 4's one end supports ground, then twist fixing bolt 5 again, make fixing bolt 5 fix extension rod 4, then all the other three bracing pieces 3 all expand in proper order after support ground can, so can make the ladder both sides have the holding power, form conical bearing structure, so that the ladder can not rock about but, increase its safety in utilization, can draw in bracing piece 3 in bar recess 2 in when no portable and deposit.
Example 1: the limiting mechanism is a limiting plate 10 which is arranged at the upper end of the strip-shaped groove 2 and extends downwards, and is shown in figure 2.
Example 2: the limiting mechanism is a slope 11 arranged at the upper end of the strip-shaped groove 2, and is particularly shown in figure 3.
The strip-shaped groove 2 is preferably provided with a mounting hole 6 in threaded connection with the fixing bolt 5, and the support rod 3 can be fixed in the mounting hole 6 by screwing the fixing bolt 5 into the support rod 3 when the support rod 3 is placed in the strip-shaped groove 2.
The preferable every both sides of this embodiment ladder body 1 all are equipped with bracing piece 3 for support more steadily.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
