Abstract

The utility model provides a distributing box under a passenger train, which comprises a box body with a downward opening and a box door matched with the box body. A lower edge of the box body is in 180-degree gapless bending, the end part of the box body is 90-degree horizontal bending which forms a stop edge, a waterproof buffer pad adheres to the lower plane of the stop edge, the edge of the bent box door is provided with the half I-shaped bending, when the box door is closed, the upper edge of the half I-shaped bending tightly clings to the waterproof buffer pad. The problem that seeper causes the corrosion of the box door of the distributing box is solved and the service life of the box door of the distributing box is prolonged.

Description

Coupling box under the passenger train car

Technical field

The utility model relates to coupling box under the passenger train car.

Background technology

Coupling box as shown in Figure 3 under the existing passenger train car, the design original intention of U type groove structure is in order to make the coupling box sealing property better in its chamber door, but find in actual use, produce ponding in the U type groove owing to make easily during the flushing vehicle, long-time ponding causes the coupling box corrosion phenomena to take place, thus the sealing property of having influence on.

The utility model content

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and coupling box under a kind of passenger train car is provided, and can avoid ponding to cause the corrosion of coupling box chamber door, improves the useful life of coupling box chamber door.

In order to solve above technical problem, coupling box under the passenger train car that the utility model provides, comprise downward opening casing, the chamber door that cooperates with casing, described casing lower edge is 180 ° of no gap bendings, the end is that 90 ° of levels are bent to form the backstop limit, and the lower plane on described backstop limit posts the waterproof cushion pad, and bending chamber door edge has the bending of half I shape, after chamber door was closed, the top of described half I shape bending and described waterproof cushion pad were fitted and are compressed.

Further, in the coupling box, the downside angular range of half I shape at described bending chamber door edge bending is 75 °～85 ° under the utility model passenger train car.

Further, in the coupling box, the downside angle of described half I shape bending is 80 ° under the utility model passenger train car.

The utility model coupling box chamber door changes into embedded, and casing lower edge structure adopts the bending of no gap, does not have the welding node, and at first this bending structure has been saved the space, and the opening when making the chamber door open mode is bigger, is convenient to the box house wiring; Secondly form a slope at casing and the vertical junction of chamber door, the entering of water in the time of can preventing to wash vehicle even there is low amounts of water to rush in the place, slit of chamber door and casing, also can be flowed out automatically, can not produce ponding, the final problem of coupling box that effectively solve because of the ponding corrosion; Moreover the bending structure to make that the casing chamber door all is out of shape less, avoided in the similar embedded door structure causing chamber door less because the bottom half bending takies the chamber door area, be not easy to the defective of wiring; At last, the chamber door that size is littler can improve the sealing property of casing.

As seen, the utility model ingenious conception, simple in structure, flexible and convenient to use.The utility model will be widely used in field of track traffic, have good market prospects.

Embodiment

Embodiment 1

Coupling box under the passenger train car of present embodiment, as shown in Figure 1, comprise downward opening casing 1, the chamber door 2 that cooperates with casing 1, described casing lower edge is 180 ° of no gap bendings, the end is that 90 ° of levels are bent to form backstop limit 3, the lower plane on described backstop limit 3 posts waterproof cushion pad 4, bending chamber door edge has half I shape bending 5, after chamber door is closed, the top of described half I shape bending 5 and described waterproof cushion pad 4 are fitted and are compressed, and the downside angle of the half I shape bending 5 at described bending chamber door 2 edges is 80 °.

The utility model coupling box chamber door 2 changes into embedded, and casing lower edge structure adopts the bending of no gap, does not have the welding node, and at first this bending structure has been saved the space, and the opening when making the chamber door open mode is bigger, is convenient to the box house wiring; Secondly form a slope in casing 1 and chamber door 2 vertical junctions, the entering of water in the time of can preventing to wash vehicle even there is low amounts of water to rush in the place, slit of chamber door 2 and casing 1, also can be flowed out automatically, can not produce ponding, the final problem of coupling box that effectively solve because of the ponding corrosion; Moreover the bending structure to make that the casing chamber door all is out of shape less, avoided in the similar embedded door structure causing chamber door less because the bottom half bending takies the chamber door area, be not easy to the defective of wiring; At last, the chamber door that size is littler can improve the sealing property of casing.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
