Abstract
The utility model discloses a kind of ladder, including two side levers and the multiple climbing cross bars being fixed between two side levers, the bottom of every side lever is connected with support triangular prism by rotating shaft, one end of the rotating shaft is provided with through hole and rotating shaft and is set with axle sleeve, the axle sleeve is fixed on the one side of support triangular prism, the axle sleeve, which is provided between multiple column-shaped projections and adjacent two column-shaped projections, forms a bayonet socket, and the bayonet socket and through hole are by inserting door bolt plugged and fixed.The utility model causes ladder can be according to space size or demand adjustment and the angle on ground, support triangular prism increases the contact area on ladder and ground, increase the frictional force with ground, so that ladder is not easy to slide, ladder can be guaranteed safely in use, and security performance is high, it can be operated with less space, meanwhile the utility model will not be overturn during ladder use so that ladder forms fixed angle with ground.
Description
Technical field
The utility model belongs to daily living article technical field, and in particular to a kind of ladder.
Background technology
In daily life, when people climb operation ladder be must instrument.The most basic purposes of ladder is
Ascend a height.With the raising being showing improvement or progress day by day with people's security precautions of science and technology, H.D basis is climbed disclosure satisfy that
On, security is another important indicator that people select ladder.The patent of Application No. 200420025117.7 discloses one
Kind of ladder, it is designed with support frame in the both sides of terraced body, and the support frame is tripod, specifically include support frame body and with
The spike that support frame body is connected.Although the ladder solves the problems, such as that ladder easily slides so that ladder is using process
Middle safety has certain guarantee, but is the defects of the ladder：The spike floor space of ladder is larger, it has not been convenient in smaller space
Operation.
Utility model content
The purpose of this utility model is to solve technical problem present in prior art, there is provided it is a kind of it is simple in construction,
The ladder that performance easy to use, safe is good, can be operated in smaller space.
In order to achieve the above object, the utility model uses following technical scheme：A kind of ladder, including two side levers and
The multiple climbing cross bars being fixed between two side levers, the bottom of every side lever is connected with support triangular prism by rotating shaft, described
One end of rotating shaft, which is provided with through hole and rotating shaft, is set with axle sleeve, and the axle sleeve is fixed on the one side of support triangular prism, the axle
Put provided with a bayonet socket is formed between multiple column-shaped projections and adjacent two column-shaped projections, the bayonet socket and through hole are by inserting
Fasten plugged and fixed with a bolt or latch.
Further, the top of the side lever is provided with jack and the top of side lever is fixedly connected with safe chain, the peace
The free end of full chain is connected with chain and inserts door bolt.
Further, the two sides bottom of the support triangular prism is provided with detent projection.
Further, the column-shaped projection forms eight bayonet sockets between eight and column-shaped projection.
The utility model has the advantages that compared with the prior art：Ladder of the present utility model leads in the bottom of side lever
Cross rotating shaft and be connected with support triangular prism, side lever bottom can be along axis of rotation so that ladder can adjust according to space size or demand
With the angle on ground, support triangular prism increases the contact area on ladder and ground, increases the frictional force with ground so that ladder
Son is not easy to slide, and ladder can be guaranteed safely in use, and security performance is high, and can be operated in less space makes
With, meanwhile, the axle sleeve for being fixed on the one side of support triangular prism is provided with multiple column-shaped projections and adjacent two column-shaped projections
Between formed a bayonet socket, in the through hole and a pair of bayonet sockets corresponding with through hole of rotating shaft insert insert door bolt just can be locked by rotating shaft,
Ladder will not be overturn in use so that ladder forms fixed angle with ground.In addition, the utility model is in side
The top of bar is provided with jack and the top of side lever is fixedly connected with safe chain, and the free end of safe chain is connected with chain and inserted
Safe chain, after ladder position is fixed, can be bolted on the object of climbing by door bolt, and chain is inserted in door bolt insertion jack, be prevented
Ladder departs from supporting object when only operating, and further increases the security performance of ladder.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, a kind of ladder, including two side levers 1 and multiple climbings for being fixed between two side levers 1 it is horizontal
Bar 2, the top of side lever 1 is provided with jack 10 and the top of side lever 1 is fixedly connected with safe chain 11, the free end of safe chain 11
It is connected with chain and inserts door bolt 12, the bottom of every side lever 1 is connected with support triangular prism 4 by rotating shaft 3, supports the both sides of triangular prism 4
Face bottom is provided with detent projection 13, and detent projection 13 can further increase the frictional force with ground, and one end of rotating shaft 3 is provided with through hole
5 and rotating shaft 3 on be set with axle sleeve 6, axle sleeve 6 is fixed on the one side of support triangular prism 4, and axle sleeve 6 is provided with eight column-shaped projections 7
And a bayonet socket 8, bayonet socket 8 and through hole 5 are formed between two adjacent column-shaped projections 7 by inserting 9 plugged and fixeds of door bolt.
In use, the side lever 1 of ladder is leaned against close in the supporting object of climbing target, the bottom of side lever 1 can around the shaft 3
Rotate, side lever 1 and the angle of inclination on ground are adjusted according to space size and demand, after to be adjusted, in the through hole 5 of rotating shaft 3
