Problems solved by technology

This connection structure is that the vertical handrail and the longitudinal handrail are connected by bolts between the two halves of the Huff clamp, which is likely to cause large and uneven connection gaps. At the same time, the exposure of the fasteners poses a safety hazard, which affects the appearance and increases the production of the product. Cycle time, procurement cost, and installation man-hours increase the cost of the vehicle

Abstract

The invention relates to an invisible connecting structure for a crossed handrail of a rail vehicle. The invisible connecting structure comprises a vertical handrail, a longitudinal handrail, a connecting rod and a connecting shaft, wherein the connecting rod is a round pipe with a screw hole and one sealed end, a threaded sleeve is horizontally arranged in the vertical handrail, the connecting rod is horizontally and fixedly arranged at the side surface of the vertical handrail through a hexagon bolt and the threaded sleeve, and the connecting rod and the longitudinal handrail are sheathed on the connecting shaft and are respectively fixed with the connecting shaft through sunk screws, so the connecting rod and the longitudinal handrail are fixed into a whole. The connecting structure has the advantages that the handrail realizes the crossed connection through a transition element and an internal connecting element, a fastening element at the connecting part is fixedly arranged at the upper part which cannot be easily seen by passengers, and the integrity and the attractive appearance of the handrail and the connecting part are ensured in the appearance aspect, wherein the cost of parts adopted at the connecting part of the crossed handrail is low, the processing is easy, the production period is short, and the connecting structure of the existing crossed handrail is greatly improved in the appearance and cost aspects.

Description

technical field [0001] The invention relates to an invisible connection structure of a rail vehicle cross armrest, in particular to an invisible connection structure between an upper vertical armrest and a longitudinal armrest, and belongs to the technical field of rail vehicle interior decoration. Background technique [0002] At present, the connection between the vertical armrest and the longitudinal armrest on the rail vehicle is mostly used with Huff clips. This connection structure is that the vertical handrail and the longitudinal handrail are connected by bolts between the two halves of the Huff clamp, which is likely to cause large and uneven connection gaps. At the same time, the exposure of the fasteners poses a safety hazard, which affects the appearance and increases the production of the product. Cycle time, procurement cost, and installation man-hours increase the cost of the vehicle. Contents of the invention [0003] The technical problem to be solved by ...
