Technical Field

[0001] The utility model relates to the technical field of shrinkage and deformation, in particular to a high-molecular silicone anti-shrinkage and deformation silicone seal. Background Art

[0002] Silicone rubber, also known as silicone rubber, is a rubber material containing silicon.

[0003] In the prior art, silicone is often made into seals due to its excellent weather resistance, safe and environmentally friendly material, and hygroscopic properties. Sealing rings are common silicone seals.

When subjected to external pressure, the solid structure has weak pressure resistance and is easy to cause deformation of the silicone seal. The resilience is poor, and the inner ring is easily expanded outward under pressure during the extrusion process, which is easy to deform and is not conducive to long-term use.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figures 1 to 7 The utility model provides a technical solution: a polymer silicone anti-shrinkage and deformation silicone seal, a sealing ring 1 is provided with a groove 4 inside, a connecting block 5 is fixed to the inner wall of the groove 4, a plurality of connecting blocks 5 are provided, and the plurality of connecting blocks 5 divide the groove 4 into a plurality of identical groups, and the outer surface portion subjected to pressure will support the corresponding upper steel sheet 2 or lower steel sheet 3.

[0026] A first telescopic rod 9 is fixed to the surface of one side of the upper steel sheet 2, a storage block 7 is sleeved on the outer surface of the first telescopic rod 9, a second telescopic rod 12 is arranged inside the storage block 7, a lower steel sheet 3 is fixed to the end of the second telescopic rod 12, and the contraction of the telescopic rod will drive the baffle to move in the storage groove 15, and the movement of the baffle will squeeze the spring 16 to contract the spring 16, and the contracted spring 16 will decompose the external pressure on the sealing ring 1.

[0027] On the basis of Example 1, in order to prevent the silicone sealing ring 1 from shrinking and deforming, a positioning groove 6 is opened on the side surface of the connecting block 5, the upper steel sheet 2 is arranged on the inner wall of the groove 4, the first slider 8 is fixed to the side surface of the upper steel sheet 2, the first baffle 10 is fixed to the end of the first telescopic rod 9, the second slider 13 is fixed to the side surface of the lower steel sheet 3, and the second baffle 11 is fixed to the end of the second telescopic rod 12.

[0028] A through hole 14 is provided on the surface of the storage block 7, and the through hole 14 penetrates the storage block 7. A storage groove 15 is provided on the inner wall of the through hole 14, and a spring 16 is provided on the inner wall of the storage groove 15. The upper steel sheet 2 is located on one side of the storage block 7, and the lower steel sheet 3 is located on the other side of the storage block 7.

[0029] There are multiple groups of first sliders 8, which are symmetrically distributed on the side surface of the upper steel sheet 2; there are multiple groups of second sliders 13, which are symmetrically distributed on the side surface of the lower steel sheet 3; a group of upper steel sheets 2 and lower steel sheets 3 are arranged in a group of grooves 4.

[0030] There are multiple groups of positioning grooves 6, which are symmetrically distributed on the side surface of the connecting block 5, and the first slider 8 and the second slider 13 correspond to the positioning grooves 6. The first slider 8 and the second slider 13 are clamped in the positioning grooves 6 and are movably connected, which plays a positioning role in the movement of the lower steel sheet 3 and the upper steel sheet 2, and also plays a positioning role in their reset to prevent them from offset during movement.

Due to the elasticity of the spring 16, when the external pressure disappears, the reset of the spring 16 will push the baffle to move, causing the steel sheet to reset. The reset of the steel sheet will drive the sealing ring 1 to reset, thereby achieving the characteristics of the silicone sealing ring 1 with good resilience and not easy to deform, which is conducive to long-term use.
