Description
Technical field
The utility model relates to railroad train access door, particularly railroad train access door locking mechanism assembly.
Background technology
In passage of train, there is a fan access door at each joint two ends, compartment, and Main Function is for the isolation between corridor, compartment and guest room, reduces noise.Passage of train door can ± 90 ° of rotations, with facilitate passenger in corridor dealing walking.In general door shield on traditional railway passenger train passage door is in access door opening procedure, prevents door and wall from colliding, and installs a door shield on the wall, only plays position-limiting action, door can not be fixed.On the other hand, the various door-inhales of prior art, magnetic touch, or magnetic force is more weak, cannot stand the vibration of train operation, otherwise outstanding floor or metope more, be not only repugnant to the eye but also take up room, being not suitable with train narrow space, vibrating strong environment.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of passage of train door locking mechanism assembly, can either positive lock passage of train door, can not take too many space again.
The utility model solve the technical problem, the technical scheme adopted is, passage of train door locking mechanism assembly, comprise Spring Card, only card, only deck, it is characterized in that, described Spring Card is made up of steel bar bending, there is symmetrical structure, described steel bar head and the tail relatively, form the "eight" shape structure that a neck shrinks, described only card is symmetrical wedge structure, and its waist depression is mated with Spring Card neck shaped, described only card axis of symmetry overlaps with described Spring Card axis of symmetry, and described only fastening is stopped on deck.
The technical solution of the utility model, the critical piece of access door lock locking mechanism is Spring Card, only card and stops deck.Wherein Spring Card adopts steel bar bending to form, its height is determined by steel bar cross dimensions, minimum can lower than 5mm, and the height only blocked is suitable with it, even if add the thickness of only deck, also can control to the height within 10mm, no matter be arranged on floor or on sidewall, all can not give prominence to too many, substantially can not the occupying volume external space.Spring Card of the present utility model and only cartoon are crossed downthrust and are realized occlusion, have suitable positioning intensity, also can not depart from, and unlock also leicht fallen D/A in train operation vibration.
Recommend, described spring card and only deck are arranged on bottom passage of train door respectively with on floor.
Locking mechanism assembly of the present utility model, because aspect ratio is lower, be particularly suitable for being arranged on on floor bottom access door, its existence is discovered hardly, and also can not take action on floor cleaning and personnel produces other impact.
Preferably, described only card and the only as a whole structure of deck.
Because only the outstanding only deck of card is few, only card and only deck can adopt overall structure, carry out processing and manufacturing by casting, forging or Sheet Metal Forming Technology, there is structure simple, firmly, the feature that cost of production is low.
Recommend, described overall structure is made up of stamping parts.
Adopt stamping parts to form the overall structure of only blocking and stopping deck, production technology is simple, cost is minimum.
Further, described locking structure assembly also comprises spring stand, and described Spring Card is fixed on described spring stand.
Spring Card is fixed on spring stand by this programme, not only more attractive in appearance, and conveniently installs and fix.
Further, described spring stand is provided with groove, and described Spring Card axis of symmetry overlaps with described groove axis of symmetry.
Spring stand arranges groove, as the gathering sill stopping card, only locking position can be helped, due to the existence of groove, suitably can increase and only block height, make to stop card and be engaged with Spring Card more reliable.
The beneficial effects of the utility model are, passage of train door lock locking mechanism assembly structure is simple, easy for installation, with low cost.When passage of train door reaches desired location, door can be fixed, facilitate the discrepancy of passenger.Only card and Spring Card thinner, be arranged on bottom access door and on floor, do not noted, do not affect the appearance, passenger being passed through without any impact, not space, station.

Detailed description of the invention
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
Passage of train door locking mechanism assembly of the present utility model, critical piece comprises Spring Card, only card and stops deck.Wherein Spring Card adopts and has certain flexible steel bar (or steel wire) bending formation, only blocking and stopping deck to adopt the metal material such as steel to make, only card and after only deck both can complete respectively, be fixed together by techniques such as welding, riveted joints, also can adopt forging, casting or Sheet Metal Forming Technology etc., make integrally-built only card and stop deck.
Embodiment
This routine passage of train door locking mechanism assembly, comprise Spring Card 1, only card 2, only deck 3 and spring stand 4.This routine Spring Card 1 structure as shown in Figure 1, is made up of the spring steel bar bending of the wide 5mm of thick 1mm, has symmetrical structure, and steel bar head and the tail relatively, form the "eight" shape structure that neck 10 place shrinks.Because steel bar protrudes to centre at this place, form narrow gap.This example only card 2 is symmetrical wedge structure, as shown in Figure 2, and its waist 20 place depression and Spring Card 1 neck 10 place form fit.Only card 2 axis of symmetry overlaps with Spring Card 1 axis of symmetry, and this example only card 2 will to be stopped card 2 and is fixed on stopping and stops on 3, card after 3, card machines respectively.Only card 2 height b is suitable with Spring Card 1 steel bar width, and be also 5mm, only deck adopts the steel plate that a=2mm is thick, and as shown in Figure 3, whole component height (a+b) is 7mm.No matter this routine passage of train door locking mechanism assembly, be arranged on floor or on sidewall, all can not give prominence to too many, substantially can not the occupying volume external space.This routine spring card 1 and only deck 3 are arranged on bottom passage of train door respectively with on floor, when access door is opened to desired location, Spring Card 1 slides into waist recessed position 20 place along the lozenges stopping card 2, realizes occlusion by downthrust, door is fixed, as shown in Figure 5.Wedge shape is stopped card 2 waist 20 place depression and is protruded form fit with Spring Card 1 neck 10 place, forms firmly interlocking pattern, has suitable positioning intensity, also can not depart from train operation is jolted.When needs unlock, due to leverage, slightly firmly sliding door can shake off Spring Card, shuts the door.
This routine locking structure assembly also comprises spring stand 4, and its structure as shown in Figure 6.This spring stand 4 adopts thickness to be that the cold-rolled steel sheet of 2mm is made, and spring stand 4 center is provided with groove 41, and its width d should slightly larger than the width c of only card 2, so that not interrupted when only card 2 moves wherein.This routine Spring Card 1 can be fixed on spring stand 4 by carrying out spot welding A, B at 2, and Spring Card 1 axis of symmetry overlaps with the axis of symmetry of groove 41, as shown in Figure 7.For the ease of installing, this example stops deck 3 and is processed with 2 installing holes 30 above, and spring stand 4 is processed with 2 installing holes 40 above, all adopts counter bore structure.
Only card of the present utility model and only deck also can adopt Sheet Metal Forming Technology etc., and make the overall structure of integration, this stamping parts can reduce cost of production further.
