Description
Technical field
The present invention relates to vehicle body of railway vehicle design field, a kind of particularly railcar passenger seat mounting structure.
Background technology
Passenger seat is the essential part of railcar, and quantity is more, almost along the elongated cloth of whole vehicle body side wall
Put, and seat load is frequent, and whole seat mounting structure needs to have stronger bearing capacity.Therefore, seat mounting structure
Design and optimization be the car body design field important topic to be considered.
Due to designing numerous Considerations, the beam column arrangement of car body can not provide being mounted directly a little for whole for seat,
Existing seat installation is utilized in welding transition mounting seat on side wall, and then chair framework is arranged on the side on transition seat
Formula.Consider numbers of seats and force-bearing characteristics, generally require to weld a large amount of mounting seats, worker easily obscures too many location dimension
Mistake, and once welding is difficult adjustment, the flatness of mounting seat is also difficult to ensure that more seriously, excessive welding causes
The deformation influence vehicle that makes client pay close attention to the most side wall wallboard flatness attractive in appearance have a greatly reduced quality, cause late stage process adjusting non-
It is often difficult.
The content of the invention
The present invention proposes a kind of new seat mounting structure, makes full use of the design feature of beam column, avoids welding, can
Meet installation requirement, and can overcomes disadvantages mentioned above, and concrete structure is as follows：
A kind of railcar passenger seat mounting structure, including the crossbeam on framed side wallboard and framed side wallboard, crossbeam and framed side wallboard
Connection end offers die cavity, and the top surface of crossbeam offers multiple horizontal slotted holes, the both sides difference of each horizontal slotted hole
Provided with rivet hole, the sliding block for being threaded hole is equipped with each horizontal slotted hole correspondence position in the die cavity of the crossbeam,
The both sides of each sliding block are respectively provided with riveting-rack, and the riveting-rack is provided with rivet, and rivet is inserted on crossbeam corresponding
Rivet hole in；Chair framework is installed on crossbeam, offers vertical slotted hole on chair framework, it is perpendicular on the chair framework
It is corresponding with the horizontal slotted hole on crossbeam to slotted hole and be mutually perpendicular to, vertical slotted hole, horizontal slotted hole and the sliding block
Between be fixed by bolt.
Further, the fastening end of the bolt and chair framework is provided with adjust pad, and the top of adjust pad is provided with locking
Packing ring.
Further, the riveting-rack includes the fishplate bar being bonded with cavity bottom, and the rivet is fixed on fishplate bar, fishplate bar
The pressing plate for fixing sliding block is connected with the sides adjacent positioned at sliding block.
Further, when the both sides of fishplate bar are placed with sliding block, the both sides of the fishplate bar connect the pressing plate respectively.
Further, two of the sliding block both sides leave gap between fishplate bar and sliding block.
Further, the sliding block is provided with one or more screwed holes.
Compared to the prior art compared with, the advantage of the invention is that structure through calculating checking bearing capacity meet require, because
To be to use fastener（Bolt and rivet）Installation is realized, avoids welding, so as to solve because welding deformation causes seat
Plane needed for installation and the uncontrollable problem of side wall wallboard outward appearance flatness, while avoid due to weld seam caused by weld defect
Failure risk, improve the reliability of connection.And the simple structural design is compact, manufacture and installation maintenance are efficient and convenient.Separately
Outside, this organization plan is applicable not only to the installation of seat, applies also for other similar applications, versatile.Enterprise can root
According to needing to make standard component, contributed to be cost-effective.This new structure will be used widely in field of track traffic, tool
There are good market prospects.

Embodiment
Embodiment 1
The structure of the present invention is described with reference to Figure of description, concrete scheme is as follows：
As shown in Figures 1 to 7, a kind of railcar passenger seat mounting structure, including on framed side wallboard and framed side wallboard
Crossbeam 1, the connection end of crossbeam 1 and framed side wallboard offer die cavity 101, die cavity it is wide and high：80 × 46, length is the length of crossbeam 1
Degree.The top surface of crossbeam 1 offers multiple horizontal slotted holes 13, and the both sides of each horizontal slotted hole 13 are respectively equipped with rivet hole
15, it is equipped with the sliding block 2 for being threaded hole, institute with each horizontal correspondence position of slotted hole 13 in the die cavity 101 of the crossbeam 1
The shape for stating sliding block 2 is designed as square or cuboid, and position is in the short transverse of 1 die cavity of crossbeam 101 center, size design ratio
Die cavity is smaller, and such sliding block 2 has certain activity space in the short transverse of die cavity 101, it is therefore an objective to provides height for seat installation
Direction regulated quantity, while one or more screwed holes can be arranged as required on sliding block 2, fastened for bolt.It is each sliding
The both sides of block 2 are respectively provided with riveting-rack 4, and the riveting-rack 4 is provided with rivet 3, and rivet 3 is inserted on crossbeam 1 corresponding
Rivet hole 15 in；Chair framework 9 is installed on crossbeam 1, vertical slotted hole is offered on chair framework 9（It is invisible in figure）,
