Problems solved by technology

At present, the protection level of the sealed boxes for railways in the prior art is generally IP5X or lower. The protection level of these sealed boxes is not high enough. After a long time of use, the insulation level of the sealed boxes will be reduced, causing leakage or creepage. In severe cases, it may cause explosion of communication cables and signal equipment

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] As shown in the figure, the sealing structure of the sealed box of the present invention includes an accommodation groove 1 located on the upper edge of the box body, an elastic seal 2 accommodated in the accommodation groove 1, and an elastic seal arranged on the box cover for pressing against the elastic seal. The abutment plate 3 of 2, the contact surface of the abutment plate 3 and the elastic seal 2 is a plane, and the elastic seal 2 and the abutment plate 3 are pressed against each other through the pressing device arranged on the box body and the box cover. The hardness of the elastic sealing member 2 is 45-50°, the compression amount of the elastic sealing member 2 is 1-1.5 mm, and the surface flatness of the abutting plate 3 is not greater than 0.4.

[0017] The section of the receiving tank 1 is semicircular, and the ...

Abstract

The invention discloses a sealing structure for a sealing box. The sealing structure comprises an annular accommodating groove (1) positioned on an upper edge of a box body, an annular elastic sealing piece (2) accommodated in the accommodating groove (1), and a pressing plate (3) which is arranged on a box cover and is used for pressing against the elastic sealing piece (2), wherein a contact surface between the pressing plate (3) and the elastic sealing piece (2) is a plane; the elastic sealing piece (2) and the pressing plate (3) are pressed against each other through a pressing device arranged on the box body and the box cover; the elastic sealing piece (2) has the hardness of 45-50 degrees and the compression of 1-1.5mm; and the pressing plate (3) has the surface flatness of not more than 0.4. The sealing structure for the sealing box is good in sealing effect and high in insulating level, and has a protection level of IP67.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure of a railway sealing box. Background technique [0002] At present, there are a large number of cabinets equipped with communication cables and signal equipment along the railway lines of our country, such as signal cable boxes, signal transformer boxes, etc., to command and guide the normal operation of trains. Since the box is generally placed in the open air, exposed to the sun, rain, and even sand, wind and sand and other bad weather, the box is required to be a sealed box with a certain degree of protection to prevent rainwater from leaking and sand from entering. Dangerous accidents such as leakage or creepage. At present, the protection level of the sealed boxes for railways in the prior art is generally IP5X or lower. The protection level of these sealed boxes is not high enough. After a long time of use, the insulation level of the sealed boxes will be reduced,...
