The second fastener across second hole is fixed on side wall.As a result, by setting installation screw thread on vehicle body side wall, it is used for
Fasten transition bracket, replacement transition bracket easy to disassemble.
As the fixed form of another transition bracket, the transition bracket is welded on side wall.
It is caught in wedge-shaped stent for convenience, the top of the transition bracket is equipped with bar, and the both ends of the bar, which correspond to, is mounted on two
On side plate；The fixing gap for fixing wedge-shaped stent is formed between the bar and the internal face of backboard.
In order to reduce installing component, installation effectiveness, the Lumbar and handrail integrated setting are improved.
Preferably, the Lumbar is Lumbar made of stainless steel or fiber glass reinforcement.
Preferably, the connecting bracket is in integrally shape of chinese word Ji.
In order to reduce installing component, installation effectiveness is improved, the top of the Lumbar is integrated with wedge-shaped stent, institute
The lower part and connecting bracket for stating Lumbar are integrated.
In order to more reliably install by waist, the lower of wedge shape stent is higher than transition branch along positioning height when the Lumbar is installed
The upper edge of frame.During installation, the Lumbar for being integrated with wedge-shaped stent and connecting bracket is clamped on transition bracket, and is fastened.
Compared with prior art, the beneficial effects of the utility model are：The structure of the Lumbar connection structure of the utility model
Intensity is high, and easy for installation, fastener and mounting bracket are hidden in inside Lumbar, are avoided exposed.

Specific embodiment
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the feature in embodiment and embodiment in the utility model can be combined with each other.For sake of convenience, hereinafter such as
There are " on ", " under ", "left", "right" printed words, only represent consistent with the upper and lower, left and right direction of attached drawing in itself, not to structure
Play restriction effect.
A kind of Lumbar connection structure, can be applicable in any rail transit train, fastening thread is set on vehicle body side wall,
For installing transition bracket.
Specifically, as shown in figs. 1 and 6, the Lumbar connection structure includes the transition bracket 4 being fixed on side wall 2, with
And Lumbar 3.The top of the Lumbar 3 is fixed by wedge-shaped stent 5 on transition bracket 4, and the lower part of the Lumbar 3 passes through connection
Stent 6 is removably secured with transition bracket 4 to be connected.The Lumbar 3 and handrail integrated setting.
As shown in Fig. 2, the transition bracket 4 includes backboard 41, bottom plate 43 and both side plate 42；It is offered on the bottom plate 43
First hole 45, the second hole 44 is offered on the backboard 41, and 6 top of connecting bracket is provided with mounting hole；Across described first
First fastener 9 of hole 45 and mounting hole is by 4 company of being removably secured of the connecting bracket 6, the lower part of Lumbar 3 and transition bracket
It is connected together.The backboard 41 is by passing through second fastener 10 in second hole 44 to be fixed on side wall 2.The transition branch
The top of frame 4 is equipped with bar 46, and the both ends of the bar 46, which correspond to, to be mounted on both side plate 42；The internal face of the bar 46 and backboard 41 it
