Embodiment Construction

[0014] see figure 1 , figure 1 It is a schematic diagram of the cross-sectional structure of the flat sealing strip with ribs on the bottom and serrations on the bottom of the present invention. Depend on figure 1 It can be seen that the straight sealing strip with protruding bottom and sawtooth on the bottom of the present invention includes a sealing strip body 1, the sealing strip body 1 is in the shape of a straight strip, the upper part of the sealing strip body 1 is square, and the lower part is circular, and the sealing strip body 1. The material is EPDM rubber. In the sealing strip body 1, three cavities 2 are arranged in parallel along the length direction of the sealing strip body 1. Two of the cavities 2 are arranged in parallel on the upper part of the sealing strip body 1, one left and one right. Its cross-section is circular, and another hole 2 is arranged at the lower part of the sealing strip body 1. Set to sawtooth.

Abstract

The invention relates to a straight sealing strip with a bottom rib and top saw teeth, and is mainly used for sealing ship cargo hatch covers. The straight sealing strip comprises a sealing strip body (1); the sealing strip body (1) is in the shape of a straight strip; the upper part of the sealing strip body (1) is square, and the lower part of the sealing strip body (1) is round; the sealing strip body (1) is made of ethylene-propylene-diene copolymer; three holes (2) are formed in the sealing strip body (1) in parallel along the length direction of the sealing strip body (1); two of the three holes (2) are arranged at the upper part of the sealing strip body (1) in parallel left and right, and the cross sections of the two holes are round; the other hole (2) is formed in the lower part of the sealing strip body (1), and the cross section of the hole (2) is triangular; the rib (3) is arranged at the middle of the bottom part of the sealing strip body (1); the top end face of the sealing strip body (1) is designed to be a serrated face (4). The straight sealing strip provided by the invention is high in compressive deformation and higher in elasticity, so that the airtightness is relatively higher; matching mating faces between the straight sealing strip and other parts cannot slip.

Description

(1) Technical field [0001] The invention relates to a rubber sealing strip. It is mainly used for the sealing of ship cargo hatch covers. It belongs to the technical field of rubber seals. (2) Background technology [0002] Before the present invention was made, the sealing strips currently used for the sealing of ship cargo hatch covers were all made of solid straight strip structure by EPDM. The compression deformation of the sealing strip is small and the elasticity is poor, so the sealing performance is relatively weak. (3) Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a flat sealing strip with ribs on the bottom and sawtooth on the bottom with large compression deformation and good elasticity. [0004] The object of the present invention is achieved in this way: a straight sealing strip with ribs on the bottom and sawtooth on the bottom, including a sealing strip body, the sealing strip bo...
