drop shape; the water-drop-shaped design of the sealing strip main body is perfectly attached to an abutted seam formed by splicing glass, so that the sealing strip main body can be better attached to a sealing surface when being pressed, effective sealing is formed, the sealing effect is improved, after the sealing strip main body is installed, the abutted seam can be seen to be finer and more uniform through the outer end of the glass, and the sealing effect is improved. The sealing strip has the advantages that the sealing strip is simple in structure, deformation of the abutted seam caused by resistance of the sealing strip body is avoided, the sealing strip at the
tail end is hidden in the abutted seam, the appearance of the abutted seam is not affected, the sealing strip body made of the
silica gel material has good elasticity and
weather resistance, and the anti-pressure capability and stability of the sealing strip body can be enhanced by matching with the reinforcing ribs arranged inside.
