Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle through-channel components, in particular to an efficient sealing structure for vehicle through-channels. Background Technique
[0002] The through-channel is mainly installed at the connection between two adjacent carriages of a train, so as to form a complete channel at the end of the car, enabling it to have good telescopic performance, fire prevention, rain prevention, sound insulation and noise reduction, and the ability to pass through curved movements. It ensures the safety of vehicle operation and at the same time improves the comfort of the passenger travel environment during train operation.
[0003] The through-channel of rail transit vehicles generally consists of a tarpaulin assembly, a bottom plate assembly, a top plate assembly and a side plate assembly. Both ends of the tarpaulin assembly are sealed with the side plate assemblies on both sides through sealing rubber strips. The outside of the sealing rubber strips is exposed to the external environment. For some urban rails that are aerial rails, these sealing rubber strips will be exposed to long-term sunlight and direct scouring by rainwater, shortening the service life of the sealing rubber strips. To solve the above problems, we propose this efficient sealing structure for vehicle through-channels. Content of the Utility Model
[0004] The main purpose of the utility model is to provide an efficient sealing structure for vehicle through-channels, which can effectively solve the problems in the background technique.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The efficient sealing structure for vehicle through-channels includes two track mounting frames and a tarpaulin. A plurality of first mounting holes are provided on the side walls of the track mounting frames and both side walls of the tarpaulin. A third sealing rubber strip is provided on the side wall of the track mounting frame. A protection mechanism for preventing the third sealing rubber strip from being exposed to sunlight is provided on both side walls of the tarpaulin. The protection mechanism includes a first sealing frame provided on the side wall of the tarpaulin. Mounting rings are fixedly connected to both side walls of the tarpaulin. A blocking mechanism for blocking dust from entering is provided on both side walls of the tarpaulin.
[0007] Preferably, the blocking mechanism includes a second sealing frame fixedly connected to the side wall of the tarpaulin, and a plurality of first placement grooves are provided on the side wall of the track mounting frame.
[0008] Preferably, a first mounting groove is provided on the side wall of the first sealing frame, and a first sealing rubber strip is provided in the first mounting groove.
[0009] Preferably, a second mounting groove is provided on the side wall of the second sealing frame, and a second sealing rubber strip is provided in the second mounting groove.
[0010] Preferably, a plurality of second mounting holes are provided on the side wall of the track mounting frame, and threaded holes are provided on both side walls of the tarpaulin.
[0011] Preferably, a plurality of second placement grooves are formed in the side wall of the track mounting frame, and the second placement grooves are disposed opposite to adjacent second mounting holes.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The device is provided with a protection mechanism. When the third sealing strip is pressed against the mounting ring, the first sealing frame on the outside protects it from dust and sunlight, preventing the third sealing strip from being directly washed by strong sunlight and a large amount of rainwater, thereby improving the sealing efficiency of the through-channel.
[0014] 2. The device is provided with a blocking mechanism, which can seal and protect the inner side of the third sealing strip, reducing the influence of external environmental factors on the sealing strip, such as ultraviolet rays (received by specular reflection), oxygen, temperature changes, etc., extending the aging time of the sealing strip, and improving the sealing structure.
[0015] 3. The device is provided with a first sealing strip. When the third sealing strip is pressed tightly, the first sealing strip can protect the third sealing strip, further reducing the influence of rainwater, etc. on the third sealing strip, thereby improving the sealing performance of the through-channel.
