Abstract
The utility model relates to a kind of urban railway carriage through passage refractory slab retaining mechanism,The retaining mechanism include refractory slab pin shaft,Limit spring and refractory slab attachment base,The refractory slab pin shaft includes the pin shaft end of handle end and connection handle end,Symmetrically arranged two card slots are had on the pin shaft end,The top at the pin shaft end is machined with chamfering; The top surface of the limit spring has a through-hole,Two sides are symmetrical two position-limited claws; The refractory slab attachment base in "
" shape structure, upper and lower two end faces are machined with through hole, and there are two car body mounting holes for side end face processing; Being connected and fixed for through hole of the pin shaft end on refractory slab attachment base on the refractory slab pin shaft, the interior realization refractory slab of two card slots that limit spring is installed on pin shaft end by two position-limited claws and headwall, makes refractory slab realization quickly connect extension and solves volume.
Description
Technical field
The utility model relates to a kind of rail traffic vehicles group A kits, specifically a kind of urban railway carriage through passage refractory slab catch gear.
background technology:
The continuous development of each big or middle urban track traffic in recent years, rail traffic vehicles various parts produce market demand is day by day strong, as the vitals of city railway vehicle---be flexible coupling parts and run-through channel with interior structure between two joint car bodies, also answer the market demand to constantly bring forth new ideas simultaneously and vary.The wherein critical component refractory slab of run-through channel and headwall bindiny mechanism, most structure connecting extension fast, separate and compile and reasonableness, safety, can not to lay equal stress in reliability, this structure well addresses this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of urban railway carriage through passage refractory slab catch gear, refractory slab couples together with headwall by this catch gear quickly and safely, improve refractory slab to connect extension and separate volume efficiency, meet run-through channel and connect the requirement of hanging and separating volume fast, be guaranteed in safety and reliability simultaneously, improve overall reasonableness, aesthetic property and applicability.
The technical solution of the utility model is achieved in that this catch gear comprises refractory slab bearing pin 1, limit spring 2 and refractory slab Connection Block 3, described refractory slab bearing pin 1 comprises the bearing pin end 5 of handle end 4 and connecting handle end 4, with symmetrically arranged two draw-in grooves 6 on described bearing pin end 5, the top of described bearing pin end 5 is processed with chamfering 7; The end face of described limit spring 2 is with a through hole 8, and both sides are two symmetrical position-limited claws 9; Described refractory slab Connection Block 3 in "
" shape structure, upper and lower two end faces are processed with through hole 10, and side end face is processed with two car body mounting holes 11; Bearing pin end on described refractory slab bearing pin 15 is through the through hole 10 on refractory slab Connection Block 3, and limit spring 2 is installed on by two position-limited claws 9 in two draw-in grooves 6 on bearing pin end 5 and realizes being connected and fixed of refractory slab and headwall, makes refractory slab realize connecting fast and hang and separate volume.
Good effect of the present utility model is: when making the vitals refractory slab of urban railway carriage vehicle run-through channel install and run, achieve refractory slab connect extension fast and separate volume, meet run-through channel and connect the requirement of hanging and separating volume fast, be guaranteed in safety and reliability simultaneously, improve overall reasonableness, aesthetic property and applicability.Be applicable to all trolley coachs.
