Fig. 3 is partial enlarged view at the B in Fig. 1.
Specific embodiment
In order to make those skilled in the art better understand the present invention program, below in conjunction in the embodiment of the present invention
Attached drawing, the technical scheme in the embodiment of the invention is clearly and completely described.
As shown in Figure 1-3, to achieve the goals above, the invention adopts the following technical scheme: a kind of family that durability is high
With staircase, including support 1, two support devices that are separately positioned on left and right end on support 1, setting is in 1 front side of support and left end branch
The first locking device between support arrangement, the second locking device being arranged between 1 rear side of support and Right side support device, setting
Two stretching devices in 1 front and back side of support.
The support device of left end includes two hinges 2 for being rotatably arranged on 1 front/rear end of support respectively, is respectively fixedly disposed at
Two deployment rods 3 of two hinges, 2 lower end are fixedly installed multiple supported holes, two deployment rod 3 in two deployment rod 3 respectively
A support rod 4 is provided between upper in every two supported hole, two support devices at left and right end are to be symmetrical set, two exhibition
Opening lever 3 is separately positioned on 1 rear end of 1 front end of support and support.
The groove that a front and back penetrates through is provided in the support rod 4, the cross sectional shape of the groove is wavy, institute
The vertical sectional shape for stating support rod 4 is domed；It is able to bear bigger support force by setting arch for longitudinal section, so as to
Support rod is avoided because being bent using overlong time, inner wall can be made to be equivalent to multiple arch knots by wavy setting
Structure is supported, so as to keep the bending resistance of support rod stronger；It is hollow by the way that support rod 4 to be both configured to, it can make to set
Standby weight saving.
First locking device includes the first transmission shaft for being rotatably arranged on 1 front end face of support, is fixed at the first transmission
First connecting plate 22 of axis front end, the rectangular channel being arranged on the first connecting plate 22, the front end being fixed on left end support device
Second connecting plate 23 of 2 rear end face of hinge, is consolidated the limit shaft 24 for being rotatably arranged on 23 front end face of the second connecting plate and being located in rectangular channel
Calmly be arranged in limit shaft outer surface gag lever post 125, including be fixed between the second connecting plate 23 and limit shaft 24 torsional spring,
The dovetail groove of first connecting plate, 22 front end face is set, the movable plate being arranged on front side of dovetail groove 25, is fixed at movable plate 25
Rear end face and the trapezoid block that can be moved up and down in dovetail groove, the multiple rake tooths 26 for being fixed at 25 upper surface of movable plate,
It is respectively fixedly disposed at two fixture blocks 27 of 26 or so end face of rake tooth, is fixed at the lifting of trapezoid block Yu trapezoidal trench bottom
Spring, the pull rod 527 for being fixed at 25 lower end of first movement plate, multiple perforation that 24 outer surface of limit shaft is set, first
Locking device and the second locking device are to be symmetrical set；It can make the platform of ladder the top by the setting of four hinges
Increase, the tool used is needed when so as to put various constructions, takes construction equipment, lead to without repeating upper descending stair
It crosses when removing the support device of left end to the left, limit shaft 24 slides in rectangular channel, so as to adjust according to actual needs
Ladder uses height；It can be by the support device of left end with first by the setting of the first locking device and the second locking device
Locking device blocks, and allows the second locking device to block the support device of right end with same method, so as to work as existing hinge
Ratchet in chain can be blocked two support devices at left and right end using the first locking device and the second locking device when damaging, from
And avoid because the ratchet damage in hinge cannot keep ladder and stablize upright state and fall operator from ladder,
From generation safety accident is avoided, to improve the safety of equipment；The upper and lower surface of two deployment rods 3 is disposed as arch,
So as to improve the support force of deployment rod 3, to prevent the middle bent during use of deployment rod 3；By rake tooth from
Setting is highly successively increased from left to right, when so as to avoid being stuck in rake tooth in perforation when ladder does not strut completely, because
Height for rake tooth is too low and rake tooth can not be stuck in perforation completely, to increase the stability of equipment；And
When rake tooth is not stuck in perforation, the excessively high rake tooth in right side will drive limit plate 25 and rotate counterclockwise, wear when rake tooth is stuck in
It stops rotating when in hole, so as to be convenient for positioning on ladder, thus using more convenient；It can by the setting of two snap-gauges
Avoid using when rake tooth intensity it is disconnected by card not enough in perforation, so that intensity is increased, so that it is safer to use equipment.
The stretching device of front side includes two fixed plates on the front support bar 4 being respectively fixedly disposed in two support devices
5, it is rotatably arranged on two second driving shafts of two fixed plates, 5 front end face respectively, is respectively fixedly disposed at two second driving shafts
Two third connecting plates 6 of outer surface, are separately positioned on two at two connecting plates 8 for being respectively fixedly disposed at two 6 one end of third connecting plate
Two connecting shafts perforated, be rotatably arranged in two perforation on connecting plate 8, the stretching device of front side and the stretching device of rear side are
Front and back is symmetrical arranged, and two connecting plates 8 are front-back staggered setting.
The hinge is the prior art, and so it will not be repeated.
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment should fall within the scope of the present invention.
