Description
Technical field
The utility model discloses a kind of for the passenger seat on trolley coach, a kind of collapsible passenger seat with safe and reliable catch gear specifically.
Background technology
Along with the development of China's economic construction and scientific and technological progress, the railway of China has been realized great-leap-forward development, extensive railway construction efficiently advances, a collection of main construction is constructed and put into operation in succession, technology innovation is obtained a collection of new great achievement, high speed railway construction and international cooperation make important progress, and passenger and freight transportation creates the highest again.
In order to adapt to the new situations of Leap-forward Development of Railway, traditional in-vehicle device facility cannot meet the needs of development of the situation, in-vehicle device facility is carried out to the transformation of hommization, to improve the problem of putting in track passenger train installation and the supporting producer of parts that become attractive in appearance of traveling comfort, practicality, safety and the environment inside car of passenger vehicle.
Structurally there is a lot of shortcoming and defect in common trolley coach tip-up set, is in particular in: 1. seat only has cushion, there is no backrest, the oad of tip-up set is less, the traveling comfort of taking is poor, easily tired, is not suitable for people and takes the long period; 2. when passenger leaves seat, cushion is upwards dug automatically at the effect lower front end of spring device, and cushion can not stop at level attitude; 3. neither one failure-free catch gear makes cushion maintenance level or folded state, for meeting in trolley coach compartment position near passage when flow of personnel amount is larger, has enough large space, is convenient to people and walks.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of backed folding seat of being with is provided, and this seat is when passenger leaves seat, and cushion can be lockable according to passenger's needs, still remains on level attitude; And when flow of personnel amount is larger, cushion again can be folding according to people's needs, reserve enough large space, be convenient to people's walking.
The purpose of this utility model is achieved in that this folding seat comprises cushion, back cushion and support frame, it is characterized in that: it also comprises catch gear, described catch gear is by plug, axle sleeve, spring, fixed hub nut, ball, limiting stopper and horizontal fixed stop and formation, wherein, described plug, spring and ball are successively set in axle sleeve, described axle sleeve is fixed on the adapter plate arranging in cushion by two fixed hub nuts, described each limiting stopper is near ball setting, on limiting stopper, be provided with vertically two grooves, simultaneously also with a spacing preiection, between described two grooves along the circumferential direction with a track slideway, described horizontal fixed stop be arranged on spacing preiection in cushion under.
In described cushion, be symmetrically arranged with two catch gears, adapter shaft is arranged in cushion, and the limiting stopper on described catch gear is arranged on the two ends of adapter shaft.
The center-point setting of the shaft centre line of described limiting stopper, the shaft centre line of axle sleeve and ball at grade.
Two grooves on described limiting stopper are cushion level and the positioning groove of digging.
The utlity model has following advantage and good effect:
1, the utility model seat has overcome the deficiencies in the prior art and shortcoming, and when passenger leaves seat, cushion can be lockable according to passenger's needs, still remains on level attitude; And when flow of personnel amount is larger, cushion again can be folding according to people's needs, reserve enough large space, be convenient to people's walking.
2, the utility model seat have simple and reasonable, operation and easy to use, the advantage such as overturn freely, reliability is higher, maintenance cost is low, can be used in the public transport meanss such as subway, light rail, for passenger brings convenience.
