DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Embodiment one

[0025] Please refer to Figures 1-5 The utility model discloses an anti-aging hollow composite rubber strip, including pressing part 1 and sealing part 2, still including protective part 3, wherein:

[0026] Pressing part 1 includes outer protective layer 11 and sponge rubber layer 12 in the inner side of outer protective layer 11, and the first cavity 13 is arranged in the sponge rubber layer 12;

[0027] Sealing part 2 includes sealing rubber strip 21 that is integrally formed at the bottom of sponge rubber layer 12, a plurality of sealing strips 22 are symmetrically installed on the outer side of sealing rubber strip 21, and the second cavity 23 is arranged in sealing rubber strip 21;

[0028] Protective part 3 includes a plurality of closing strips 31 arranged at the bottom of sponge rubber layer 12.

[0029] Please refer to the attached Figure 2 Outer protective layer 11 is polyurethane rubber material, outer protective layer 11 is arc-shaped and is fixed at the upper end of sponge rubber layer 12, a plurality of support strips 14 are installed in the first cavity 13 away from the inner side of outer protective layer 11, and the side of support strip 14 close to outer protective layer 11 is a plane.

[0030] Specifically, the outer protective layer 11 of polyurethane rubber material on the outer side of pressing part 1 protects sponge rubber layer 12, when impacted, outer protective layer 11 first bears the impact, sponge rubber layer 12 deforms under stress and contacts support strip 14 to avoid excessive deformation and damage, thereby improving the service life of sponge rubber layer 12.

[0031] Please refer to the attached Figure 3 A plurality of reinforcing strips 24 are symmetrically installed on the inner wall of second cavity 23, and the symmetrically arranged reinforcing strips 24 correspond to each other and are arranged obliquely downward.

[0032] Specifically, the adhesive strip needs to press the pressing part 1 to press the sealing part 2 into the sealing position during installation. When the sealing part 2 is pressed into the sealing position by the pressing part 1, the reinforcing strip 24 in the sealing adhesive strip 21 can support the sealing adhesive strip 21 laterally during pressing installation, so as to avoid excessive deformation and cracking of the sealing adhesive strip 21 when it is pressed.

[0033] Further, the sealing adhesive strip 21, the supporting strip 14 and the sealing strip 22 are all made of EPDM. Example two
