Embodiment Construction

[0016] like figure 1 The sealing strip shown is made of flexible material rubber. The cross-section of strip top 1 and strip body 2 is a T-shaped structure. On the left side 3 of the bar body, the right end of the bar top is connected to the obliquely downward skirt 9. The strip body 2 is a hollow structure, and several buffer rods 7 are connected between the opposite sides of the hollow structure. The right side surface 4 of the strip body 1 is provided with several horizontal elastic rods 8 , and the elastic rods 9 are arranged at intervals on the right side surface of the strip body 2 . The advantage of the hollow structure is that it saves material and increases the elastic space of the sealing strip. The buffer rod 7 plays the role of strengthening the structural strength of the sealing strip and buffering and adjusting the external pressure in the hollow structure.

[0017] like figure 2 As shown, the sealing strip is installed on the left top cover 10 of the split ...

Abstract

The invention discloses a sealing strip for a split open top cap of a rail wagon. The sealing strip is characterized by being made of a flexible material and comprising a strip body, a strip top, a mortise and a tenon, wherein the sections of the strip body and the strip top form a T-shaped structure; the right lateral surface of the strip body is a plane; the mortise is positioned on the lower left side of the strip top; and the tenon is positioned on the left side of the strip body. The sealing strip is skilful in structure, convenient to use and low in cost, realizes sufficient waterproof, rainproof, sand-proof and dustproof sealing performance of the open wagon of the split open top cap, and has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of components for railway freight cars, and in particular relates to a sealing fitting for a split top cover of a railway freight car. Background technique [0002] Railway wagons are mainly divided into carriage type and open type, among which the open type is more suitable for the production of bulk goods under mining conditions. But wherein, in order to prevent dust and rain, open railway wagons are often equipped with top covers, including integral and split top covers. Among them, the split top cover is more flexible and fast in the control of the opening and closing of the top cover. However, because the two top covers are opened and closed, there are often gaps and looseness at the junction of the two top covers, which cannot achieve the anti-corrosion effect of the top cover. Rain, waterproof, dustproof and sandproof functions. Contents of the invention [0003] The technical problem to be solved...
