Abstract
The utility model provides a double-layer sealing side wall door of a cab, which solves the problems of rain prevention and heat insulation. The double-layer sealing side wall door provides a technical scheme as follows: the side wall door of the cab adopts a double-layer sealing structure; a first sealing hollow adhesive tape is mounted on the periphery of the outer side of a door; the compression amount of the hollow adhesive tape is 5mm to 8mm; a second sealing planar adhesive tape is mounted on the periphery of the inner side of the door; after the side wall door of the cab is closed, the hollow adhesive tape and the sealing planar adhesive tape are compressed between the side wall door and a door frame of the cab; the side wall door of the cab adopts a linkage door lock with secondary compression function; and a drain groove and a drain hole are formed on the door frame at the lower part of the door, the drain groove is communicated with the space between double-layer sealers, and the drain hole is communicated with the door outside. The utility model has the benefits of improving the sealing grade and the sealing effect of the side wall door of the cab, and then reducing the unnecessary consumption for the auxiliary power of the cab; and even seeping into the first sealer, the rainwater can be discharged out of the vehicle through the drain groove and the drain hole.
Description
Technical field
The utility model relates to the locomotive automobile door structure, is specifically related to a kind of double-layer seal drivers' cab side wall door.
Background technology
At present, the drivers' cab side wall door 1 of locomotive cab side wall door that has such as HXN3 locomotive adopts steel list hermetically-sealed construction 2, and this list sealing joint strip is the hollow adhesive tape, is bonded in the inboard of door; Student portion does not have the discharge structure (see figure 1); This structure exists the possibility of rainwater by the rotatable parts infiltration drivers' cab inboard of single sealing or drivers' cab side wall door lock, and prolongation along with operate time, sealing function can reduce because of aging, the distortion of adhesive tape, the possibility that causes leaking increases greatly, brings greater inconvenience to the driver and conductor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of double-layer seal drivers' cab side wall door, increases bilateral hermetically-sealed construction, door bottom increase discharge structure by opposite house, reaches effect rainproof, insulation.
The utility model is taked following technical scheme: drivers' cab side wall door adopts double-layer sealing structure, and the doorframe of opposite house bottom increases the stainless steel discharge structure;
The described drivers' cab side wall outer side of door periphery installing first road sealed hollow adhesive tape, the decrement of hollow adhesive tape is about 5 millimeters～8 millimeters, inner peripheral is installed the second road sealing plane adhesive tape, after drivers' cab side wall door was closed, hollow adhesive tape and plane adhesive tape were squeezed state between drivers' cab side wall door and doorframe;
Described drivers' cab side wall door adopts the linked door lock with secondary compression function;
The discharge structure of described drivers' cab side wall student department frame is to be provided with rhone and drain hole at the bottom doorframe, and rhone is communicated with space in the middle of the bilateral sealing, and drain hole leads to outdoors.
The utility model is compared with existing drivers' cab side door and is had following beneficial effect:
Owing to take the sealing grade of bilateral sealing the raising greatly drivers' cab side door and the sealing effectiveness after the long-time utilization, not only avoid rainwater to infiltrate drivers' cab, and avoid cold air or hot air to enter, thereby reduced the unnecessary consumption that causes the locomotive auxiliary power owing to poorly sealed; Owing to take bilateral close,, also can by the second road sealing plane adhesive tape retaining in rhone, discharge outside the car by drain hole even a small amount of rainwater infiltrates the first road sealed hollow adhesive tape.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Fig. 1 is existing drivers' cab side door schematic diagram;
Fig. 2 is a drivers' cab side door double-layer sealing structure schematic diagram;
Fig. 3 is drivers' cab side door bottom double-layer sealing structure and discharge structure schematic diagram.
Accompanying drawing mark: existing drivers' cab side wall door 1, steel list hermetically-sealed construction 2, doorframe 3, hollow adhesive tape 4, door 5, door lock 6, lock nose 7, plane adhesive tape 8, drivers' cab floor 9, drain hole 10, rhone 11, space 12.
The specific embodiment
The outstanding feature of the utility model is exactly by bilateral hermetically-sealed construction and discharge structure, reaches the effect of sealing.
As shown in Figure 2, drivers' cab side wall door adopts double-layer sealing structure, install the first road sealed hollow adhesive tape 4 at drivers' cab side wall outer side of door, hollow adhesive tape 4 is made by ethylene propylene diene rubber, hardness is Shao Shi 30～40, has good weatherability, anti-ozone and ageing properties, has favorable mechanical performance, elasticity and anti-wear performance, hollow adhesive tape 4 uses the powerful two-sided tape of Minnesota Mining and Manufacturing Company to stick on the periphery, and the decrement of hollow adhesive tape 4 is about 5 millimeters～8 millimeters; Hollow adhesive tape 4 can guarantee to stop rainwater and air to enter as main hermetically-sealed construction substantially.The door 5 inner door panel periphery installing second road sealing plane adhesive tape 8, plane adhesive tape 8 is a rubber expanded material, decrement is big, good seal performance, plane adhesive tape 8 uses bonding adhesive to stick on the door-plate; Stopping a small amount of rainwater of the possibility infiltrate first road sealed hollow adhesive tape 4 and entering of air, is the active booster action of double-layer seal.After drivers' cab side wall door was closed, hollow adhesive tape 4 and plane adhesive tape 7 were squeezed state between drivers' cab side wall door 5 and doorframe 3, have good sealing function.
Adopt linked door lock 6 and lock nose 7 at drivers' cab side wall door in addition with secondary compression function, this door lock 6 is with the phase-locked ratio of existing common door, has the secondary compression function, i.e. being rotated counterclockwise and locking nose 7 by handle with the leverage between lock body, produce secondary compression, make the decrement and the sealing duration of bilateral sealing joint strip reach designing requirement, make the sealing effectiveness of side door perfect more.
As shown in Figure 3, the doorframe 3 in door 5 bottoms increases the stainless steel discharge structure, comprises rhone 11 and drain hole 10, and rhone 11 seals middle space 12 with bilateral and is communicated with, and drain hole 10 leads to outdoors; Close in the closed procedure at door, the air of door 5 lower space 12 can in time be discharged, and simultaneously a small amount of rain-water drainage groove 11 and the drain hole 10 of the infiltrate first road sealed hollow adhesive tape 4 is discharged outside the car.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
