The rear end of the connection rod is provided with an inner threaded hole and fixed in the horizontal U-shaped installation adjusting hole of the U-shaped support through second bolts, the front end of the connection rod is provided with outer threads which are matched with an inner threaded hole installation hole on the lower portion of the screen handle. The subway vehicle flexible adjustable screen installation structure is flexible and adjustable, convenient to install, small and exquisite in structure, stable and solid, coordinating and unifying in visible parts and the screen handle, and truly beautiful and practical. The installation sequence of the screen and the seat is not restrained, so that installation during a subway vehicle manufacturing process and maintenance after the subway vehicle is operated are facilitated.
Description
Technical field
The utility model relates to the flexible adjustable screen mounting structure of a kind of railcar, belongs to the subway interior structure.
Background technology
The guest room screen is the in-built inner important component part of subway, and is firm after installing for guaranteeing screen, needs at least three not coplanar attachment points, limits the degree of freedom of its three directions.General screen front end is provided with one attachment point is installed, because screen is close to seat, the limited space that provides.Simultaneously, screen is as in-built part, interface satisfy can not affect under the prerequisite of function attractive in appearance.The mounting structure of existing screen does not have adjustable mechanism, so that the installation underaction of screen, bad adaptability.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned deficiency of prior art, provides a kind of railcar flexible adjustable screen mounting structure.
In order to solve above technical matters, the flexible adjustable screen mounting structure of the railcar that the utility model provides, composition comprises: the screen handrail, with the fixing screen of screen handrail, it is characterized in that: also comprise U-shaped support, pipe link, described U-shaped support has the flanging of two outwards, described flanging offers vertical U-shaped installation adjustment hole, the central authorities of described U-shaped support offer horizontal U-shaped installation adjustment hole, two flangings of described U-shaped support are fixed on the cushion frame by the first bolt, the rear end of described pipe link offers internal thread hole, and the rear end of pipe link is bolted on the horizontal U-shaped installation adjustment hole of U-shaped support by second; The front end of described pipe link has the outside thread with screen handrail below negative thread mounting hole coupling.
Further, the middle part of described pipe link is provided with the outer-hexagonal nut, is convenient to spanner this pipe link is installed.
Characteristics of the present utility model are: adjustable flexibly, easy for installation, structure is small and exquisite, and firmly stable, visible part and the coordinating and unifying of screen handrail are really accomplished both artistic and practical.Simultaneously, though the installation of screen is fixed by means of cushion frame, but structure of the present utility model makes both installation sequencings unrestricted, namely improved the installation independence of screen and seat, make things convenient for the installation of vehicle manufacturing process and the maintenance after the car operation, independence and maintainability are the another large advantages of the utility model.

The specific embodiment
As shown in Figures 1 to 4, the flexible adjustable screen mounting structure of the railcar of the present embodiment, composition comprises: screen handrail 1, with the fixing screen 2 of screen handrail 1, U-shaped support 3, pipe link 4, U-shaped support 3 has the flanging 31 of two outwards, flanging 31 offers vertical U-shaped installation adjustment hole 32, the central authorities of U-shaped support 3 offer horizontal U-shaped installation adjustment hole 33, two flangings 31 of U-shaped support 3 are fixed on the cushion frame 6 by the first bolt 5, the rear end of pipe link 4 offers internal thread hole 41, and the rear end of pipe link 4 is fixed on the horizontal U-shaped installation adjustment hole 33 of U-shaped support 3 by the second bolt 7; The front end of pipe link 4 has the outside thread 42 with screen handrail 1 below negative thread mounting hole 8 couplings.The middle part of pipe link 4 is provided with outer tetragonal nut 3, can be the outer-hexagonal nut also, is convenient to spanner this pipe link is installed.Among Fig. 1,9 is seat cover.
The utility model utilizes cushion frame as the screen front end fixing support to be installed, and design plan is as follows: at first, at cushion frame U-shaped support is installed, and the different U-shaped installation adjustment hole of katal on the support, its effect comprises: a, provide the mounting interface of screen front end; The error of bringing in b, the installation of elimination screen, cushion frame installation and the seat cover installation process.Secondly, reserve tapped mounting interface on the screen handrail, as seen this interface owing to exposing, and profile is cylinder, and the surface adopts the wire drawing identical with the screen handrail to process.At last, adopt threaded cylinder rod member as transition piece (end is outside thread, other end negative thread) between screen and the support, band outside thread one end is screwed in the screen handrail interface, and band negative thread one end then is connected with U-shaped support by bolt.This rod member outside face adopts wire drawing to process equally.
Installation process is as follows:
1, is preinstalled with riveting nut on the cushion frame, bolt by M6 is installed to U-shaped support on the cushion frame, place between support and the skeleton and adjust pad, owing to U-shaped the support adjustable orifice of opening and the use of adjusting pad, realized the controllability (for pipe link) of three directions;
2, by reserving circular hole on the seat cover, pipe link is screwed in the screen handrail interface;
3, use the bolt of M8 that the pipe link installation is fixed on the U-shaped support.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
