Abstract
The utility model relates to an inner door sill for a subway built-in door. The inner door sill comprises a rectangular aluminum alloy section and an upper pressing plate, and has the key points that antiskid patterns are arranged on the upper pressing plate, the upper pressing plate is connected with the floor of a vehicle body through a countersunk head screw, and the rectangular aluminum alloy section is mounted on the vehicle body through a fillister head screw. The inner door sill adopts a split type structure, has the advantages of simple and reliable structure, convenience in mounting, good wearing resistance, large adjustable range and attractive integral effect, can adapt to the vehicle body structure without an interlayer floor at the lower part, well meets the mounting and adjusting requirements of the built-in door on an aluminum alloy vehicle body without the interlayer floor, and effectively solves the problem that the built-in door is easy to scrape the side wall of the vehicle body.
Description
Technical field
The utility model relates to the built-in door in railcar guest room, specifically relates to the built-in gate threshold in railcar guest room.
Background technology
Threshold is the critical component of the built-in door of subway motion guide in the railcar guest room, is used for becoming built-in student's guide groove with outer threshold mutual group, directly rubs with door leaf, plays the motion guide effect.Interior threshold commonly used mainly is made up of aluminium alloy extrusions in the built-in door system of railcar at present, is monolithic, is used to have the body construction on interlayer floor, regulates adjustable extent ± 3mm by the C type groove that is installed in the bottom.Threshold can not be suitable for the car body that the bottom does not have C type groove in this kind, and adjustable extent too small (door leaf and adhesive tape error have ± 2.5mm), when car body bottom, side wall and door leaf error accumulation, this kind threshold can not meet design requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing threshold, provide a kind of simple in structure, easy for installation, abrasion resistance is good, adjustable extent is big, can adapt to the bottom and do not have threshold in the built-in door of subway on interlayer floor.
Threshold is made up of square type aluminium alloy extrusions and top board in the built-in door of subway of the present utility model, and its main feature is: described top board is provided with anti-skid design, is connected with car body floor with sunk screw; Described square type aluminium alloy extrusions is installed in car body by fillister head screw.In order to realize this purpose better, described anti-skid design surface scribbles 0.015-0.02mm oxide film wearing layer;
Described square type aluminium alloy section surface scribbles 0.01-0.05mm oxide film wearing layer.
The utility model adopts split-type structural, and simple and reliable for structure, easy for installation, abrasion resistance is good, can adapt to the body construction that the bottom does not have the interlayer floor, and adjustable extent is big, and whole structure is attractive in appearance.Satisfy the installation of built-in door on the aluminum alloy bodywork on no interlayer floor well and adjusted requirement.Solved the problem of built-in Men Yiyu car body side wall scraping effectively.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, top board, 2, square type aluminium alloy extrusions, 3, fillister head screw, 4, car body, 5, sunk screw, 6, anti-skid design.
The specific embodiment
Threshold is made up of square type aluminium alloy extrusions 2 and top board 1 in the built-in door of subway of the present utility model.Square type aluminium alloy extrusions 2 is installed on the car body 4 by fillister head screw 3, and square type aluminium alloy section surface is a 0.03mm oxide film wearing layer, and between the car body 4 by the pad adjustment, adjustable range increases to ± 6mm.Square type aluminium alloy extrusions is installed earlier, and top board 1 is pushed down square type aluminium alloy extrusions 2 and installed, apart from outermost rubbing surface 1mm.Top board 1 is provided with anti-skid design 6, and anti-skid design 6 surfaces scribble 0.018mm oxide film wearing layer.After square type aluminium alloy extrusions 2 installed, top board 1 was installed on the car body floor with sunk screw 5 again, and front end is apart from rubbing surface 1mm.Head of screw is with concordant, attractive and durable above the top board 1.
