Description

A kind of suspension type pull fold-away stairway
Technical field
This utility model relates to Modern Traffic equipment technology field of transport, and a kind of suspension type pull of concrete offer folds to be held up Ladder.
Background technology
In the field such as life, mechanical engineering or transportation, ascending a height operation for convenience of operator, staircase is utilization rate One of higher instrument, especially during the use of van, tank truck and other special-purpose vehicles, it is often necessary on car body Handrail is installed so that personnel's climbing, completes the maintenance to car body region of interest and trimming.As a example by refrigerated truck, cold preservation Casing carries out repacking design on the basis of original vehicle chassis, and box sizes is the biggest, then the bearing capacity of casing also can be got over Greatly.Tradition staircase is taken up space relatively big, for avoiding and the problem such as car body interferes, it is necessary to the size of restriction casing.But, right In the overall dimensions of a car of vehicle, there is strict standard in country, so the size of staircase is had strict demand.
In the patent documentation of Patent No. CN201679221U, disclose a kind of support means.This support means includes two Root standpipe, connects between two standpipes and has the transverse tube being parallel to each other, be connected for rotating shaft, two between the termination of transverse tube and standpipe Connecting between root standpipe has inclined tube, one end of described inclined tube to be connected with a standpipe rotating shaft therein, and the other end of inclined tube is with another Connect for hook between a piece standpipe.Owing to there is no joint on inclined tube, inclined tube can be made to be close to transverse tube, improve support means Stability in the large.But, the support means of this structure takes up room relatively big, applies in the conditional vehicle of overall dimensions, holds Easily collide with car body, there is certain limitation.
Summary of the invention
In order to solve with present on problem, this utility model provides a kind of structure design advantages of simple, convenient installs, just In carrying, saving vehicle space, range is extensive, and the suspension type pull fold-away stairway that safety is higher.
For achieving the above object, this utility model provides following technical scheme:
A kind of suspension type pull fold-away stairway, including stull and vertical brace, also includes fixing angle steel and spacing angle steel, described vertical Support is made up of fixing vertical brace and activity vertical brace, and fixing angle steel is fixing with fixing vertical brace to be connected;Stull is arranged on fixing vertical brace and work Between dynamic vertical brace, it is hingedly connected with fixing vertical brace, activity vertical brace;Described spacing angle steel is fixed in fixing vertical brace, stull When being horizontal, the top edge of spacing angle steel is inconsistent with the lower limb of stull.
Described stull is formed by the transformation of the way of rustless steel square tube, and spacing angle steel is formed by the steel angle profile transformation of the way.
The length of described stull is not more than the distance between two adjacent crossbrace.
During use, by fixing angle steel, staircase is fixed in the facade structures such as casing or metope.Hold up during use Ladder is in open mode, and the top edge of spacing angle steel is inconsistent with the lower limb of stull, and spacing angle steel supports stull, makes stull Upper surface is horizontal, it is simple to operator climb.When need not use staircase, mobile activity vertical brace, by activity Vertical brace is closed together with fixing vertical brace, can at utmost save the space that staircase takies.
As preferably, also including that plug pin portion, described plug pin portion are made up of keeper and latch, keeper is fixed on fixing vertical In support, and on keeper, offer hole, location;Latch is fixed in activity vertical brace, and when staircase is in closure state, latch is with fixed The position in hole, position is corresponding.
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.
