Lifter, it is characterised in that: the lifter is installed on inside guardrail, and the lifter includes lifting arm on first, lifting on second
Arm, first it is lower lift arm, second it is lower lift arm and screw rod, arm is lifted on described first and the first lower arm of lifting is hinged by first connecting portion,
Arm is lifted on described second and the second lower arm of lifting is hinged by second connecting portion, is arranged in the first connecting portion and second connecting portion
The through hole for having work screw rod end to pass through lifts on described first and lifts arm on arm and second and be installed on top, and described first lower lifts
Arm and the second lower arm of lifting are mounted on the base, and the screw both end is respectively arranged with positive pitch thread and anti-pitch thread, described to pass through
The screw thread matched with screw rod is provided on hole.
Preferably, the lifter two sides are arranged by limit plate.
Preferably, the limit plate and guardrail weld.
Preferably, the top upper end is provided with mounting hole.
Preferably, the pedestal is installed on attachment base, and the attachment base lower end is provided with universal wheel.
Preferably, the connection seat both sides are outward extended with lug boss, and the lug boss offsets with limit plate.
Preferably, described screw rod one end is provided with handle.
Preferably, the handle stretches out mobile guardrail surface.
Compared with prior art, the mobile guard bar lifting device structure of the application is simple, convenient and practical, can effectively solve to move
The lifting problem of universal wheel in dynamic guardrail, while saving space.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
The some embodiments recorded in application, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of cross-sectional structure schematic diagram of mobile guard bar lifting device in the specific embodiment of the invention；
Fig. 2 is a kind of lateral section structural schematic diagram of mobile guard bar lifting device in the specific embodiment of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out detailed retouch
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, those of ordinary skill in the art's every other implementation obtained without making creative work
Example, shall fall within the protection scope of the present invention.
In conjunction with shown in Fig. 1-2, the embodiment of the present application discloses a kind of mobile guard bar lifting device and is installed on inside guardrail, including
It lifts to lift on arm 1, second on one and lifts arm 4 and screw rod 5 under the lower act arm 3, second of arm 2., first, arm 1 and the first lower act arm are lifted on first
3 is hinged by first connecting portion 6, and arm 2 is lifted on second and the second lower arm 4 of lifting is hinged by second connecting portion 7, first connecting portion 6
With the through hole for being provided with 5 end of work screw rod in second connecting portion 7 and passing through, lifts on first and lift arm 2 on arm 1 and second and be installed on top
On first 8, the first lower act arm 3 and the second lower arm 4 of lifting are installed on pedestal 9, and screw rod 5 and the junction of first connecting portion 6 are provided with
The junction of positive pitch thread, screw rod 5 and second connecting portion 7 is provided with anti-pitch thread；First connecting portion 6 and second connecting portion 7
Through-hole is provided with the screw thread to match with screw rod 5.One end of screw rod 5 is provided with handle 13.
When rotational handle 13, lifter is realized by changing the distance between first connecting portion 6 and second connecting portion 7
Lifting., when the distance of first connecting portion 6 and second connecting portion 7 reduces, lifter is risen.When first connecting portion 6 and second connect
When the distance of socket part 7 becomes larger, lifter decline.Simultaneously as the both ends of screw rod 5 are respectively arranged with positive pitch thread and anti-tooth spiral shell
Line, therefore in rotational handle 13, first connecting portion 6 and second connecting portion 7 are in the position of screw rod 5 relative to 5 centre bit of screw rod
It sets symmetrical always, avoids in lifting process, screw rod 5 goes up and down effect toward a direction bias effect.
Meanwhile pedestal 9 is connected and fixed with universal wheel 11 by attachment base 10.In this way in rotational handle 13, realize to ten thousand
Lifting to wheel.
Preferably, top 8 is fixedly connected by screw with guardrail upper end.
As shown in Fig. 2, mobile guard bar lifting device two sides are provided with limit plate 12, limit plate 12 and mobile guardrail welding, together
When 10 two sides of attachment base extend outwardly and be provided with lug boss and supported with limit plate 12.
In the technical scheme, limit plate 12 is set in lifter two sides, prevents in lifting process, shift, really
Lifter is protected in movement in vertical direction.The lug boss that attachment base 10 is arranged is supported with limit plate, convenient for the disassembly and group of lifter
Dress.
In conclusion the mobile guard bar lifting device structure of the application is simple, and it is convenient and practical, it can effectively solve mobile guardrail
The lifting problem of middle universal wheel, while saving space.
