Description

Technical Field

[0001] The present application relates to the field of sealed boxes, and in particular to a high-speed railway industrial control equipment box. Background Art

[0002] Industrial control chassis are generally used in harsh environments. High-speed railway, referred to as HSR, refers to a railway system with high design standards and safe high-speed travel for trains. Its concept is not limited to tracks, let alone trains. High-speed railway industrial control equipment boxes are industrial control chassis on high-speed railways, and they also need to adapt to some harsh use environments, so the requirements are generally high. In some use environments, there is a possibility of water intrusion, so waterproof treatment is required. The common waterproof treatment method is generally to design the industrial control chassis into a sealed state, and then connect external lines or pipes.

[0003] The industrial control chassis includes a box body with an opening on the top and a box cover that closes the box body opening. A sealing ring is sandwiched between the box body and the box cover for waterproofing. In order to install the pipeline, a gap needs to be opened in the sealing ring. At the same time, a waterproof layer is put on the outside of the pipeline to cooperate with the sealing ring for sealing and waterproofing.

[0004] Although the above-mentioned industrial control chassis improves the sealing between the pipeline and the box body and the box cover to a certain extent through the waterproof layer outside the pipeline, the fit between the waterproof layer and the sealing ring is not high, and there is still a risk of water seeping through the gap between the waterproof layer and the sealing ring.

[0008] By adopting the above technical solution, the upper sealing rubber cover cooperates with the pipeline part of the lower sealing ring to form a clamp for the line pipe, and the clamping between the cover body and the box body is small, thereby improving the sealing of the line pipe position. Since the lower sealing ring is still a complete whole, the sealing of the box body is better, and the installation of the lower sealing ring is more convenient. Except for the position of the upper sealing cover, the lower sealing ring is a complete whole in other positions, which ensures the sealing. The size of the upper sealing cover only corresponds to the pipeline part, which makes it more convenient to install the upper sealing cover. The existence of the sealing groove is adapted to the upper sealing cover.

[0009] Optionally, the upper sealing rubber cover is interference fit in the sealing groove.

[0010] By adopting the above technical solution, the upper sealing rubber cover adopts an interference fit installation method. On the one hand, the sealing between the upper sealing rubber cover and the cover body is better. On the other hand, the upper sealing rubber cover can be installed with the cover body first, and then the installation between the cover body and the box body is completed, which plays a role of pre-positioning installation.

[0011] Optionally, both the box body and the box cover are provided with threaded half-tubes extending outward, the threaded half-tube of the box body and the threaded half-tube of the box cover are assembled to form a threaded tube, the threaded tube connects the inside and outside of the box body, the sealing tube is installed in the part of the threaded tube close to the inside of the box body, and the threaded cover is mounted on the outer thread of the threaded tube.

[0012] By adopting the above technical solution, a threaded half-tube is arranged to form a threaded tube, which is matched with a threaded cover. On the one hand, the pre-installation of the box body and the box cover is realized. On the other hand, the sealing tube is installed in the threaded tube, and the threaded cover pressurizes the threaded tube, thereby squeezing the sealing tube, thereby improving the sealing stability between the sealing tube and the line tube.

[0013] Optionally, a rubber sleeve is installed in the threaded tube, and the rubber sleeve is sleeved on the line tube.

[0014] By adopting the above technical solution, a rubber sleeve is installed in the threaded pipe, and the sealing between the threaded pipe and the line pipe is further improved by the rubber sleeve, which provides double insurance.

[0015] Optionally, the hole in the threaded tube is a stepped hole and is formed with a stepped surface, and the rubber sleeve abuts against the stepped surface.

[0016] By adopting the above technical solution, the position of the threaded sleeve is limited.

[0017] Optionally, the rubber sleeve is interference fit with the line tube, and the minimum hole diameter of the threaded cover is smaller than the outer diameter of the rubber sleeve.

[0018] By adopting the above technical solution, the threaded cover and the rubber sleeve can cooperate to fix the line pipe at a corresponding position, and the line pipe is not easily pulled out.

[0019] Optionally, the lower sealing ring is provided with a notch groove for the upper sealing rubber cover to be embedded in.

[0020] By adopting the above technical solution, pre-positioning installation can be achieved between the upper sealing rubber cover and the lower sealing ring.

[0021] To summarize, the upper sealing rubber cover cooperates with the pipeline part of the lower sealing ring to form a clamp for the line pipe, and the clamping between the cover body and the box body is small, which improves the sealing of the line pipe position. Since the lower sealing ring is still a complete whole, the sealing of the box body is better, and the installation of the lower sealing ring is more convenient. Except for the position of the upper sealing cover, the lower sealing ring is a complete whole in other positions to ensure the sealing. The size of the upper sealing cover only corresponds to the pipeline part, which makes it more convenient to install the upper sealing cover. The existence of the sealing groove is adapted to the upper sealing cover. BRIEF DESCRIPTION OF THE DRAWINGS
