Description
Technical field
The invention discloses a kind of passenger seat on trolley coach, specifically a kind of collapsible passenger seat with safe and reliable catch gear.
Background technology
Along with the development of China's economic construction and the progress of science and technology, the railway of China achieves great-leap-forward development, extensive railway construction efficiently advances, a collection of main construction is constructed and put into operation in succession, technology innovation obtains a collection of great achievement newly, 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 traveling comfort of passenger vehicle, practicality, the attractive in appearance of safety and environment inside car become the problem of pendulum in track passenger train installation and the supporting producer of parts.
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, does not have backrest, the oad of tip-up set is less, the traveling comfort taken 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 the position of close passage in trolley coach compartment when flow of personnel amount is larger, having enough large space, being convenient to people's walking.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of band backed folding seat, this seat is when passenger leaves seat, and cushion can be lockable according to the needs of passenger, still remains on level attitude; And when flow of personnel amount is larger, cushion can fold according to the needs of people again, reserve enough large space, be convenient to people's walking.
The object of the present invention is achieved like this: 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 that arranges in cushion by two fixed hub nuts, described each limiting stopper is arranged near ball, limiting stopper is provided with vertically two grooves, simultaneously also with a spacing preiection, along the circumferential direction with a track slideway between described two grooves, described horizontal fixed stop to be arranged in cushion immediately below spacing preiection.
Be symmetrically arranged with two catch gears in described cushion, 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 of the shaft centre line of described limiting stopper, the shaft centre line of axle sleeve and ball is disposed on the same plane.
The positioning groove that two grooves on described limiting stopper are cushion level and dig.
The present invention has the following advantages and good effect:
1, seat of the present invention overcomes the deficiencies in the prior art and shortcoming, and when passenger leaves seat, cushion can be lockable according to the needs of passenger, still remains on level attitude; And when flow of personnel amount is larger, cushion can fold according to the needs of people again, reserve enough large space, be convenient to people's walking.
2, seat of the present invention has simple and reasonable, operation and easy to use, overturns freely, the advantage such as reliability is higher, maintenance cost is low, can be used in the public transport means such as subway, light rail, for passenger brings convenience.

Detailed description of the invention
By accompanying drawing 1, 2, 3, shown in 4: this folding seat comprises cushion 1, back cushion 2 and support frame 4, is characterized in that: it also comprises the catch gear 3 be symmetricly set on by adapter shaft 16 in cushion 1, and described catch gear 3 is by plug 5, axle sleeve 6, spring 7, fixed hub nut 8, ball 9, be arranged on limiting stopper 10 and the horizontal fixed stop 11 at adapter shaft 16 two ends and form, wherein, described plug 5, spring 7 and ball 9 are successively set in axle sleeve 6, and described axle sleeve 6 is fixed on the adapter plate 12 of setting in cushion 1 by two fixed hub nuts 8, and described each limiting stopper 10 is arranged near ball 9, limiting stopper 10 is provided with vertically two grooves 13, simultaneously also with a spacing preiection 14, along the circumferential direction with a track slideway 15 between described two grooves 13, the shaft centre line of described limiting stopper 10, the shaft centre line of axle sleeve 6 and the center-point of ball 5 are disposed on the same plane, and described horizontal fixed stop 11 is arranged on immediately below cushion 1 inner limited block 10 upper limit projection 14, the positioning groove that two grooves 13 on limiting stopper 10 are cushion 1 level and dig.
Described cushion 1 and back cushion 2 are made up of welded framework, flame-retardant high-resilience isocyanurate foam, fire retardant felt, fire-retardant cloth cover, velcro.When cushion 1 upwards overturns, the upper surface of cushion 1 and the surface contact of back cushion 2, namely the contact of two cushion surface, both reduced crash shock, also can not send sound.
When passenger leaves seat, cushion 1 is lockable, and still remains on level attitude (shown in Fig. 5).When lifting cushion 1 front end with have gentle hands, when namely giving one, cushion 1 front end directed force F upwards, cushion upwards could turn over and turn 90 degrees.This function facilitates passenger when leaving, return to seat temporarily, repeatedly need not do rotary movement; When to leave seat for a long time and maybe need to allow open walk, just seat is dug (shown in Fig. 6).
