Oil level visual window type is generally made up of oil level glass, sealing gasket, oil ga(u)ge lid etc., and this kind of structure needs bigger installing space, and oil level glass is easily subject to slungshot impact, organic solvent can not be used to clean simultaneously, working service inconvenience; And plug screw screw-in type is unreasonable due to structural design at present, oil leakage phenomenon often occurs, use to gear-box and bring security risk.
Summary of the invention
It is an object of the invention to provide a kind of installation, working service conveniently, safe and reliable, and the railway vehicle gear case oil level display device of compact conformation.
For achieving the above object, the technical scheme is that a kind of railway vehicle gear case oil level display device, including cock, reflecting piece, spacer ring, sealing ring and transparent glass, described cock has mesopore, the outer surface of cock has external thread section, and described reflecting piece, spacer ring, sealing ring and transparent glass are each attached in mesopore.
Described spacer ring includes the first spacer ring, second spacer ring, with the 3rd spacer ring, described sealing ring includes the first sealing ring, second sealing ring, 3rd sealing ring, with the 4th sealing ring, described transparent glass includes the first transparent glass and the second transparent glass, described reflecting piece, first spacer ring, first sealing ring, first transparent glass, second sealing ring, second spacer ring, 3rd sealing ring, second transparent glass, 4th sealing ring, 3rd spacer ring is sequentially arranged in mesopore, described mesopore there is internal thread segment, described first spacer ring, the periphery of the second spacer ring and the 3rd spacer ring is equipped with external screw thread, described external screw thread is all threadeded with the internal thread segment in mesopore.
Described reflecting piece is white plastic sheet.
Described reflecting piece is provided with several through hole.
The cross section of described first sealing ring, the second sealing ring, the 3rd sealing ring and the 4th sealing ring is square.
Described first transparent glass and the second transparent glass are safety glass sheet, and described first transparent glass is marked with the circular scale line that several are concentric.
The mesopore seam crossing of described first transparent glass and the second transparent glass and cock has fluid sealant.
Described cock also has radially convex shoulder, radially convex shoulder has several spanner jacks.
After adopting said structure, the railway vehicle gear case oil level display device of the present invention have employed Multi-level sealing structure, owing to there being internal thread segment in described mesopore, the outside of described first spacer ring, the second spacer ring and the 3rd spacer ring is equipped with external screw thread, and described external screw thread is all threadeded with the female thread in mesopore, therefore, threaded can compress each sealing ring by this, it is achieved the reliable location of each part, make installation, working service convenient, safe and reliable, make structure compacter simultaneously.
Owing to described reflecting piece is provided with several through hole or gap, thus it is guaranteed that lubricating oil can enter the region between reflecting piece and the first transparent glass, make oil level form show and become apparent from.
Owing to the cross section of described first sealing ring, the second sealing ring, the 3rd sealing ring and the 4th sealing ring is square, these sealing rings can either be conveniently mounted in cock, also ensures that sealing is reliable.
Owing to the mesopore seam crossing of described first transparent glass and the second transparent glass and cock has fluid sealant, therefore, it is possible to improve the sealing reliability of oil level display device further.
Owing to described first transparent glass and the second transparent glass are safety glass sheet, therefore can be effectively improved the anti-slungshot impact ability of oil level form, also can avoid the organic solvent impact on glass vision panel simultaneously, improve working service convenience.
Accompanying drawing explanation
The present invention is further detailed explanation for the embodiment provided below in conjunction with accompanying drawing.
Fig. 1 is the front view of the railway vehicle gear case oil level display device of the present invention;
Fig. 2 is the Fig. 1 sectional view along line A-A.
Detailed description of the invention
As shown in Figure 1, 2, the railway vehicle gear case oil level display device of the present invention, including cock 1, reflecting piece 2, spacer ring, sealing ring and transparent glass, described cock 1 has mesopore 1-1, the outer surface of cock 1 has external screw thread 1-2 section, and described reflecting piece 2, spacer ring, sealing ring and transparent glass are each attached in mesopore 1-1.
Such as Fig. 1, shown in 2, described spacer ring includes the first spacer ring 3, second spacer ring 7, with the 3rd spacer ring 11, described sealing ring includes the first sealing ring 4, second sealing ring 6, 3rd sealing ring 8, with the 4th sealing ring 10, described transparent glass includes the first transparent glass 5 and the second transparent glass 9, described reflecting piece 2, first spacer ring 3, first sealing ring 4, first transparent glass 5, second sealing ring 6, second spacer ring 7, 3rd sealing ring 8, second transparent glass 9, 4th sealing ring 10, 3rd spacer ring 11 is sequentially arranged in mesopore 1-1, described mesopore 1-1 has female thread 1-1-1 section, described first spacer ring 3, the periphery of the second spacer ring 7 and the 3rd spacer ring 11 is equipped with external screw thread, described external screw thread is all threadeded with the female thread 1-1-1 section in mesopore 1-1.
