Abstract
The invention discloses a top connecting structure of a middle column handrail of urban rail and subway vehicles. A T-shaped groove bolt is fixed to a ceiling section material of the vehicles through a nut and a lock washer, threads at the lower part of the bolt penetrate through a middle roof plate of the vehicles to be screwed into a connecting base with internal threads, the connecting base is of a T shape structure, external threads are arranged at the upper part of the connecting base, the lower part of the connecting base is inserted into the top of the middle column handrail and is fixed, and a decorative cover with internal threads is matched with the connecting base with the external threads and can cover a round hole in the middle roof plate. According to the top connecting structure, connection of the handrail is firm, shaking in all directions is limited, the decorative cover can be installed on the outer surface of the middle roof plate of the vehicles easily, unattractiveness caused by non-uniform gaps is effectively avoided, the structure is simplified, the machining processes are reduced, and the work efficiency is improved.
Description
Technical field
The invention belongs to city rail vehicle technical field, concretely relate to a kind of urban rail railcar central post handrail top
Portion connecting structure.
Background technology
In running, most of passenger is both needed to stand by bus city rail vehicle, so most vehicle is both provided with
Central post handrail, the reliability by this central post handrail is most important with the aesthetic property after installation.Most domestic urban rail now
It is trim to be inserted in the middle top board of vehicle and passes through trim that the top of the central post handrail employed in vehicle connects
To fix the top of central post handrail.Existing central post handrail top need to open up on the middle top board of vehicle and decorate when installing
The circular hole that lid size matches, first T-shaped connecting seat is inserted in central post handrail and is welded as a whole in advance, T-shaped connecting seat
Top cap central position on carry boss, top cover is pressed on the tube wall of central post handrail；Carry externally threaded cylinder connecting seat
Boss on the fluted position with top cap central of center band of bottom matches, cylindrical connecting seat top weld strip four
The flat board of installing hole, is fixed on ceiling section bar by screw-nut, will be cylindrical even for the boss insertion of T-shaped connecting seat during installation
In the groove of joint chair, realize the preliminary fixation of central post handrail, then from tapped trim with carry externally threaded circle
Cylindricality connecting seat carries out threaded fixation.Trim extend in vehicle this central post handrail mode that is connected
In top board, complex structure, operation is more, and the gap between trim and middle openings in the ceiling is not easy to install uniformly, easily produces pine
Dynamic also affect attractive in appearance.
Content of the invention
It is an object of the invention to overcoming the deficiency of prior art, provide one kind more attractive in appearance, rational in infrastructure, install letter
Just the urban rail railcar central post handrail top attachment structure that manufacturing procedure effectively improves work efficiency can, be reduced.
The purpose of the present invention is achieved through the following technical solutions, and a kind of urban rail railcar central post handrail top is even
Access node structure, it is structurally characterized in that：T-slot bolt is fixed on the ceiling section bar of vehicle by nut and lock washer, its bolt
Lower thread passes through the middle top board of vehicle to be screwed on tapped connecting seat, and connecting seat is fixed on the top of central post handrail
Portion.
In order to the purpose of the present invention is better achieved, described connecting seat is T-shaped structure, and top carries external screw thread, bottom
It is inserted into the top of central post handrail and fixes, carry female trim to match and energy with externally threaded connecting seat
Cover the circular hole on top board.
In order to the purpose of the present invention is better achieved, described central post handrail passes through slope with the connecting seat with internal and external threads
Mouth weldering is welded as a whole in advance.
The invention has the beneficial effects as follows by using urban rail railcar central post handrail top of the present invention attachment structure, by
In the bonding strength strengthening handrail, so that connection is more fastened, limit rocking of all directions, and be easy to make trim pacify
It is contained in the middle top outer surface of vehicle, effectively evaded the uneven aesthetic problem brought in gap；Simplify structure, decrease processing
Operation, improves work efficiency.
Brief description
Fig. 1 is the schematic diagram of urban rail railcar central post handrail top of the present invention attachment structure；
Fig. 2 is the central post handrail of the present invention, connecting seat, T-slot bolts assemblies schematic diagram.
In figure：Top board, 6- ceiling section bar in 1- trim, 2- central post handrail, 3- connecting seat, 4-T type groove bolt, 5-.
Specific embodiment
Goal of the invention, technical scheme and advantage for making the present invention are clearer, with reference in the embodiment of the present invention
Accompanying drawing, is clearly fully described by technical scheme it is clear that described embodiment is that a present invention part is real
Apply example, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.
Referring to accompanying drawing, urban rail railcar central post handrail top of the present invention attachment structure, specific structure is, T-slot
Bolt 4 is fixed on the ceiling section bar 6 of vehicle by nut and lock washer, and its bolt lower thread passes through the middle top board of vehicle
5 are screwed on tapped connecting seat 3, and connecting seat 3 is T-shaped structure, and top carries external screw thread, and bottom is inserted into central post and helps
The top of handss 2 is simultaneously fixed, and carries female trim 1 and matches with externally threaded connecting seat 3 and can cover middle top
Circular hole on plate 5.
When central post handrail 2 is installed, need to slip into T-slot bolt 4 before middle top board 5 is installed and be fastened on ceiling type
On material 6, middle top board 5 opens up circular hole in advance, the shaft of T-slot bolt 4 exposes in the circular hole of middle top board 5, under connecting seat 3
Portion's insertion central post handrail 2 is simultaneously welded as a whole in advance by groove welding, specifically as shown in Fig. 2 connecting seat 3 band female thread, whole
Body is threaded connection and is fixed on the T-slot bolt 4 being fastened on ceiling section bar 6 in advance, and entirely threaded length reaches
40mm, makes whole central post handrail 2 be firmly fixed.So far the top of whole central post handrail 2 connects fastening and completes, for making
Whole guest room is elegant in appearance, arranges a trim 1, and trim 1 carries female thread, by trim 1 and with externally threaded connection
Seat 3 is connected by screw threads for fastening and shelters from the circular hole that middle top board 5 opens up.
For the surface of top board 5 in abrasion when preventing trim 1 from installing, a circle rubber can be embedded on trim 1 in advance
Pad, rubber blanket has certain degree of hardness, ensure and middle top board 5 between after effectively controlling trim 1 to install 1mm about sky
Gap, the surface of top board 5 in not wearing and tearing when both ensure that installation, also beautify guest room environment.
Because central post handrail 2 needs to bear larger power during practice, central post handrail 2 of the present invention selects
SUS304 stainless steel tube；T-slot bolt 4 selects the T-slot bolt of M16；Trim 1 and connecting seat 3 are casting integrated molding
After carry out screw thread process, trim 1 outer surface has also carried out polishing to ensure to expose the attractive in appearance of guest room face.
