Description
Technical field
This utility model belongs to rail traffic vehicles technical field, relates to vehicle air conditioning unit, is specifically related to air conditioning unit
The non-return support means of cover plate.
Background technology
In railcar, air-conditioning plays very important role.Air-conditioning is arranged in a housing, and there is evaporation inside
Device, condenser, centrifugal blower, axial flow blower, compressor and various pipeline and control parts.Filter after running a period of time
Network capacity is easy to be dirty stifled, affects air output and the air purity of air-conditioning, so the cover plate on air conditioner set shell body needs often to open,
To take out drainage screen clean or carry out system maintenance.
When air-conditioning maintenance, lack the cover plate hand steered or temporary support of needs that specific purpose tool supports, if by outward
Power or maloperation, cover plate may accidental switch off suddenly, makes maintainer be injured by a crashing object by cover plate in the case of unwitting, causes peace
Full accident.The device that part employing pneumatic type supports can make cover plate to fix because of phenomenon of losing heart, and places for a long time or frequent
After using, this phenomenon can be even more serious, and relatively costly.
Summary of the invention
The purpose of this utility model is for a kind of special cover plate support of air conditioning unit offer, uses and has non-return structure
Sliding support, reasonable in design, be hardly damaged, sustainable fixing, support effect is good, and through placing for a long time or frequently using
Under can maintain a good state, lock and unlock conveniently.
The technical solution of the utility model is: the non-return support means of a kind of railway vehicle air conditioner cover plate, be arranged at
On the cover plate that vehicle tank is hinged, it is critical only that: this support device structure includes arranging grooved rail on the cover board, a movable end
Head is limited on grooved rail and has the connecting rod along grooved rail free sliding degree, and the connecting rod other end is articulated with on casing；Rotary spacing exists
The latch hook of connecting rod movable end and grooved rail lower surface cooperatively form cover plate non-return structure.
Further, the movable end of described connecting rod is spacing on grooved rail by sliding axle nail, and sliding axle is followed closely through grooved rail
Chute and connecting rod movable end, there is the degree of freedom along grooved rail slide.
Further, described sliding axle nail sequentially passes through grooved rail chute, axle sleeve, latch hook and connecting rod movable end, and two ends are respectively
Spacing with coupling nut and packing ring by its head, latch hook has the degree of freedom rotated around sliding axle nail.
Further, described latch hook includes connecting plate and is positioned at the folding hook bottom connecting plate, and folding hook hook is in grooved rail lower surface
Upper formation cover plate non-return structure.
Further, the side of described latch hook connecting plate is provided with and prevents from rolling over hook hook in the rib of grooved rail upper surface.Work as lid
When plate is closed, latch hook is positioned at grooved rail chute top, and vehicle concussion may cause latch hook to rotate, make folding hook hook on grooved rail upper surface
Causing cover plate to open, rib is possible to prevent the generation of this phenomenon.
Further, described grooved rail is angle bar shape structure, and coupling chute is arranged on drift angle end.Angle iron structure can make folding hook
Relatively big with the contact area of grooved rail lower surface, non-return is reliable.
Further, described connecting rod and cover plate are articulated with on casing by screw, coupling axle sleeve, back-up ring and nut.
The beneficial effects of the utility model are: firmly by cover plate opening procedure, latch hook is followed closely along grooved rail along with sliding axle
Slide, when cover plate is opened to certain angle, latch hook is affected by gravity and sagging grooved rail lower surface of hooking, it is possible to cover plate
Being supported, if now by external force or maloperation, latch hook can firmly hook chute, make cover plate stop at home, prevent
Maintainer is injured by a crashing object by cover plate in the case of unwitting；When closing cover plate, only with hands, latch hook need to be rotated to chute side；Whole
Body is reasonable in design, simple in construction, easy to maintenance, support effect good, and can protect under placing for a long time or frequently using
Hold kilter, lock and unlock conveniently.
Accompanying drawing explanation
Fig. 1 is cover plate structural representation when not fully opening；
Fig. 2 is cover plate structural representation when fully opening；
Fig. 3 is grooved rail and connecting rod, the scheme of installation of latch hook；
In accompanying drawing, 1 is casing, and 2 is cover plate, and 3 is connecting rod, and 4 is sliding axle nail, and 5 is grooved rail, and 6 is latch hook, and 6-1 is to connect
Plate, 6-2 is folding hook, and 6-3 is rib, and 7 is axle sleeve.
Detailed description of the invention
A kind of non-return support means of railway vehicle air conditioner cover plate, see accompanying drawing, cover plate 2 and connecting rod 3 by screw,
Joining axle sleeve, back-up ring and nut to be articulated with on casing 1, cover plate 2 relative vehicle casing 1 is turning to be opened, and connecting rod 3 can opposite case 1
Rotate.Grooved rail 5 by welding or is fastened on cover plate 2 by bolt, and sliding axle nail 4 sequentially passes through grooved rail 5 chute, axle sleeve 7, lock
Hook 6 and connecting rod 3 movable end, two ends are spacing with coupling nut and packing ring by its head respectively, and latch hook 6 can follow closely 4 turns around sliding axle
Dynamic.Latch hook 6 includes connecting plate 6-1 and is positioned at the folding hook 6-2 bottom connecting plate 6-1, and the side of connecting plate 6-1 is provided with and prevents folding
Hook 6-2 hook is in the rib 6-3 of upper surface, grooved rail 5 top.
When being embodied as, during firmly being opened up by cover plate 2, connecting rod 3 movable end follows closely 4 along grooved rail by sliding axle
5 slide, latch hook 6 along with sliding axle nail 4 slip, when cover plate 2 is opened to certain angle, latch hook 6 be affected by gravity and under
Hang down, hook grooved rail 5 lower surface on cover plate, it is possible to cover plate 2 is supported.If meeting high wind or maloperation causing there is closedown trend
Time, latch hook 6 can firmly hook grooved rail 5, prevents cover plate 2 from closing.When cover plate 2 closed by needs, with hands, latch hook is rotated to chute
Side, the most firmly close cover plate 2.
Support means reliability is high, solves the Problem of Failure that prior art life-time service causes: maintainability is good, needs more
When changing or safeguard, latch hook 6 is pulled down and changes, it is not necessary to carrying out welding on unit or the operation such as polishing, structure is relatively simple, behaviour
Facilitate.
