Embodiment Construction
[0013] see figure 1 , figure 1 It is a schematic diagram of the cross-sectional structure of the solid three-square cavity serrated surface sealing strip of the present invention. Depend on figure 1 It can be seen that the solid three-square hole sawtooth surface sealing strip of the present invention includes a sealing strip body 1, the sealing strip body 1 is in the shape of a straight strip, and the material of the sealing strip body 1 is EPDM rubber. 1, along the length direction of the sealing strip body 1, there are three cavities 2 arranged in parallel from left to right. The cross sections of the three cavities 2 are all square.

The invention relates to a solid sealing strip with three square cavities and serrated faces. The solid sealing strip is mainly used for sealing a cargo hatch cover of a ship. The solid sealing strip comprises a sealing strip body (1), wherein the sealing strip body (1) is in a straight strip shape and is made of EPDM (Ethylene-Propylene-Diene Monomer), three cavities (2) are arranged in the sealing strip body (1) along the length direction of the sealing strip body (1) from left to right, and the cross sections of the three cavities (2) are all square; the top end face and the bottom end face of the sealing strip body (1) are arranged into the serrated faces (3). The quantity of compressive deformation is large, the elasticity is better, and thus the sealing performance is relatively better. The top end face and the bottom end face of the sealing strip body are arranged into the serrated faces, so that the solid sealing strip cannot slip on a joint face matched with other components and parts.
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 object of the present invention is to overcome the above disadvantages, and provide a solid three-square cavity sawtooth surface sealing strip with large compression deformation and good elasticity. [0004] The purpose of the present invention is achieved in this way: a solid three-square cavity serrated surface sealing strip, including a sealing strip body, the sealing strip body is in the shape of a strai...
