Described latch is in " 7 " font.When need not use staircase, by closed together to activity vertical brace and fixing vertical brace,
Staircase Guan Bi is got up, and is inserted into by latch in hole, location simultaneously, activity vertical brace and fixing vertical brace is locked, can effectively prevent from holding up
Ladder automatically opens up.
As preferably, also include that half transverse brace structure, described half transverse brace structure are arranged on activity vertical brace bottom, with activity vertical brace
It is articulated and connected, and matches with the spacing angle steel of activity vertical brace bottom.
During use, staircase is in open mode, is opened by half transverse brace structure simultaneously, and operator can be by half stull knot
Structure climbing staircase, facilitates operator to use.
As preferably, described fixing vertical brace, the cross section of activity vertical brace are U-shape structure, stull and fixing vertical brace, activity
Vertical brace is articulated and connected by rivet respectively.Described rivet is homalocephalus semitubular rivet, reinforcement activity vertical brace and the company of fixing vertical brace
Connect fastness.
As preferably, described stull and fixing vertical brace, activity vertical brace junction are provided with elastic washer, prevent movable vertical
Shift during moving, the friction between stull and activity vertical brace, fixing vertical brace, it is effectively protected staircase, increases the service life.
Compared with prior art, suspension type pull fold-away stairway of the present utility model has a beneficial effect highlighted below:
(1) described staircase is fixed in the facade structures such as casing or metope by fixing angle steel, it is simple to install, and
Once mounting just can use for a long time, improves the ease for use of staircase；
(2) activity vertical brace, fixing vertical brace are articulated and connected by homalocephalus semitubular rivet respectively with stull, can when not using
To move activity vertical brace, staircase is closed, save staircase and take up room；
(3) staircase can be locked by described plug pin portion, strengthens the staircase Guan Bi fastness when closure state, can be effective
Prevent staircase from automatically opening up；
(4) described half transverse brace structure facilitates operator to climb, and improves practicality further.
