Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a valve-specific sealing strip made of PP material. Background Technology

[0002] The core function of sealing strips is to fill gaps and achieve a sealing function, including multiple effects such as waterproofing, dustproofing, sound insulation, heat insulation, shock absorption, and corrosion resistance. They are widely used in fields such as automobiles, construction, and electronic equipment. They come in various materials and structures to adapt to different scenario requirements. By elastically filling gaps, they block the penetration of substances such as water, air, and dust, ensuring the integrity of the sealed space.

[0003] During the daily use of valves, since valves are often installed in operating areas with frequent vibrations, the sealing strip may slightly detach from the sealing groove after being subjected to high-frequency vibrations. A tiny gap may appear between the sealing strip and the sealing groove. Existing sealing strips are mainly fixed by the friction generated by the compression between themselves and the sealing groove. Since the surface of the sealing strip is relatively smooth, this fixing method is difficult to effectively deal with the high-frequency vibrations mentioned above. Utility Model Content

[0004] To overcome the problem that the sealing strip may slightly detach from the sealing groove after being subjected to high-frequency vibration, and that a tiny gap may appear between the sealing strip and the sealing groove.

[0005] The technical solution of this utility model is as follows: a valve-specific sealing strip made of PP material, including a sealing strip body and an upper clamp, as well as a lower connecting strip and an anti-slip protrusion. The upper clamp is provided on both sides of the upper end of the sealing strip body, and the lower connecting strip is provided on both sides of the lower end of the sealing strip body. The upper surface of the upper clamp is evenly distributed with anti-slip protrusions. A hollow elastic pad for sealing is provided in the middle of the sealing strip body.

[0006] Preferably, the upper clip has two anti-slip protrusions evenly distributed on both sides of its surface, and the surface of the second anti-slip protrusion has serrated protrusions evenly distributed on its surface. The upper end of the first anti-slip protrusion is flat.

[0007] Preferably, the surface of the lower connecting strip is provided with a slot 1, and a reinforcing linear strip is provided in the slot 1, which runs through the entire sealing strip body.

[0008] Preferably, the outer side of the lower connecting strip is evenly distributed with anti-slip grooves, the surface of which is arc-shaped, and the inner side of the lower connecting strip is evenly distributed with reinforcing ribs, the surface of which is arc-shaped.

[0009] Preferably, the surface of the sealing strip body is provided with a second slot, and a reinforcing metal sheet is provided in the second slot. The reinforcing metal sheet runs through the entire sealing strip body and is used for overall support.

[0010] Preferably, the hollow elastic pad has toughening strips on both sides, and the toughening strips are positioned between the upper clip and the hollow elastic pad.

[0011] Preferably, the hollow elastic pad has a soft inner support pad inside, one end of which is connected to the inner wall surface of the hollow elastic pad, and the soft inner support pad is used for support.

[0012] The beneficial effects of this utility model are:

[0013] 1. When using this PP valve-specific sealing strip, after the upper clamp is fitted with the mounting groove, the hollow elastic pad and the upper clamp work together to seal. The hollow elastic pad can fully contact the surface of the groove, playing the main sealing role, while the upper clamp plays an auxiliary sealing role. With the cooperation of the two, the tightness of the seal is ensured. When encountering high-frequency vibration, the serrated protrusions increase the friction, and the anti-slip protrusions play the main anti-slip role and the auxiliary anti-slip role, thus ensuring that the main body of the sealing strip will not detach from the groove.

[0014] 2. The lower connecting strip is used to connect to the external mounting slot. The lower connecting strip is relatively long, so it has high strength requirements. The reinforcing linear strip is made of a material with good toughness, such as aluminum alloy. The reinforcing linear strip runs through the entire sealing strip body, thereby playing a supporting and shaping role for the lower connecting strip and preventing the lower connecting strip from undergoing large deformation during vibration.

[0015] 3. The reinforcing metal sheet is also made of a material with good toughness, such as aluminum alloy. The reinforcing metal sheet is used to shape the main body of the sealing strip and to support the main body of the sealing strip, thereby ensuring the overall strength of the main body of the sealing strip. The soft inner support pad is used to support the weak points on both sides of the hollow elastic pad to ensure that the hollow elastic pad will not be damaged. The tough strip is used to support the connection between the hollow elastic pad and the lower connecting strip to ensure that the connection will not deform or break during deformation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a valve-specific sealing strip made of PP material, comprising a sealing strip body 1 and an upper clamp 2, as well as a lower connecting strip 3 and anti-slip protrusions 4. The upper clamp 2 is provided on both sides of the upper end of the sealing strip body 1, and the lower connecting strip 3 is provided on both sides of the lower end of the sealing strip body 1. Anti-slip protrusions 4 are evenly distributed on the upper surface of the upper clamp 2. A hollow elastic pad 5 for sealing is provided in the middle of the sealing strip body 1. When this valve-specific sealing strip made of PP material is in use, after the upper clamp 2 is fitted into the mounting groove, the hollow elastic pad 5 and the upper clamp 2 work together to achieve a sealing effect. Due to its good elasticity, the hollow elastic pad 5 can fully contact the surface of the groove, playing a primary sealing role. The upper clamp 2 plays an auxiliary sealing role. With the cooperation of both, the tightness of the seal is ensured, and the sealing strip body 1 will not detach from the groove when encountering high-frequency vibration.

[0024] Please see Figure 1 and Figure 4In this embodiment, anti-slip protrusions 9 are evenly distributed on both sides of the upper clip 2. Serrated protrusions 10 are evenly distributed on the surface of the anti-slip protrusions 9. The upper end of the anti-slip protrusion 4 is flat. The surface of the lower connecting strip 3 is provided with a slot 12. A reinforcing linear strip 8 is provided in the slot 12. The reinforcing linear strip 8 runs through the entire sealing strip body 1. Anti-slip grooves 7 are evenly distributed on the outer side of the lower connecting strip 3. The surface of the anti-slip grooves 7 is arc-shaped. Reinforcing ribs 6 are evenly distributed on the inner side of the lower connecting strip 3. The surface of the reinforcing ribs 6 is arc-shaped. The surface of the sealing strip body 1 is provided with a slot 2 13, and a reinforcing metal sheet 11 is provided inside the slot 2 13. The reinforcing metal sheet 11 runs through the entire sealing strip body 1 and is used for overall support. In use, the upper clip 2 is mainly adapted to the mounting slot. After the upper clip 2 is adapted to the mounting slot, the hollow elastic pad 5 and the upper clip 2 work together to play a sealing role. Due to its good elasticity, the hollow elastic pad 5 can fully contact the surface of the slot and play a major sealing role. The upper clip 2 plays a crucial role in sealing. The upper part of the upper clip 2 has an anti-slip protrusion 4 at its top and anti-slip protrusions 9 on both sides to ensure the stability of the sealing strip body 1. This ensures that the sealing strip body 1 will not detach from the mounting groove during high-frequency vibrations. The surface of the anti-slip protrusion 9 has evenly distributed serrated protrusions 10, which increase friction. The anti-slip protrusion 9 provides primary anti-slip protection, while the anti-slip protrusion 4 provides secondary anti-slip protection. The reinforcing linear strip 8... The lower connecting strip 3 is made of a tough material, such as aluminum alloy. The reinforcing linear strip 8 runs through the entire sealing strip body 1, thereby supporting and shaping the lower connecting strip 3 and preventing it from deforming significantly during vibration. The inner side of the lower connecting strip 3 is provided with reinforcing ribs 6, which provide auxiliary support and ensure that the outer side of the lower connecting strip 3 is not easily deformed. The anti-slip grooves 7 evenly distributed on the outer side of the lower connecting strip 3 not only facilitate gripping but also increase the friction between the lower connecting strip 3 and the external mounting groove.

[0025] Please see Figure 3 and Figure 5In this embodiment, the hollow elastic pad 5 has toughness strips 14 on both sides, which are positioned between the upper clip 2 and the hollow elastic pad 5. A soft inner support pad 15 is provided inside the hollow elastic pad 5, with one end connected to the inner wall surface of the hollow elastic pad 5. The soft inner support pad 15 provides support. The surface of the sealing strip body 1 has a slot 2 13, within which a reinforcing metal sheet 11 is provided. The reinforcing metal sheet 11 is also made of a material with good toughness, such as aluminum alloy. The reinforcing metal sheet 11 is used for overall shaping of the sealing strip body 1 and provides support for the overall sealing strip body 1, thereby ensuring the overall strength of the sealing strip body 1. Because the hollow elastic pad 5 is hollow, its weak points are prone to breakage during repeated deformations. The soft inner support pad 15 supports the weak points on both sides of the hollow elastic pad 5, ensuring that the hollow elastic pad 5 will not break. The toughness strips 14 support the connection between the hollow elastic pad 5 and the lower connecting strip 3, ensuring that this connection will not deform or break during deformation.

[0026] In use, the upper clip 2 is mainly adapted to the mounting slot. After the upper clip 2 is adapted to the mounting slot, the hollow elastic pad 5 and the upper clip 2 work together to seal. Due to its good elasticity, the hollow elastic pad 5 can fully contact the surface of the slot and play the main sealing role. The upper clip 2 plays the auxiliary sealing role. With the cooperation of the two, the tightness of the seal is ensured.

[0027] The anti-slip protrusion 4 at the top of the upper clip 2 and the anti-slip protrusions 9 on both sides are used to ensure the stability of the sealing strip body 1. When encountering high-frequency vibration, it ensures that the sealing strip body 1 will not fall off the installation slot. The surface of the anti-slip protrusion 9 is evenly distributed with serrated protrusions 10. The serrated protrusions 10 are used to increase the friction. The anti-slip protrusion 9 plays the main role in anti-slip, while the anti-slip protrusion 4 plays an auxiliary role in anti-slip.

[0028] The lower connecting strip 3 is used to connect to the external mounting slot. The lower connecting strip 3 is relatively long, so it has high strength requirements. Slots 12 are evenly distributed inside the lower connecting strip 3. Reinforcing linear strips 8 are provided inside slots 12. The reinforcing linear strips 8 are made of a material with good toughness, such as aluminum alloy. The reinforcing linear strips 8 run through the entire sealing strip body 1, thereby playing a supporting and shaping role for the lower connecting strip 3 and preventing the lower connecting strip 3 from undergoing large deformation during vibration.

[0029] The inner side of the lower connecting strip 3 is provided with reinforcing ribs 6, which serve as auxiliary support to ensure that the outer side of the lower connecting strip 3 is not easily deformed. The anti-slip grooves 7 evenly distributed on the outer side of the lower connecting strip 3 not only facilitate gripping, but also increase the friction between the lower connecting strip 3 and the external mounting groove.

[0030] The surface of the sealing strip body 1 is provided with a slot 2 13, and a reinforcing metal sheet 11 is provided in the slot 2 13. The reinforcing metal sheet 11 is also made of a material with good toughness, such as aluminum alloy. The reinforcing metal sheet 11 is used for overall shaping of the sealing strip body 1 and plays a supporting role for the overall sealing strip body 1, thereby ensuring the overall strength of the sealing strip body 1.

[0031] Because the hollow elastic pad 5 is hollow, its weak points are prone to breakage when it undergoes multiple deformations. The soft inner support pad 15 is used to support the weak points on both sides of the hollow elastic pad 5 to ensure that the hollow elastic pad 5 will not break. The toughness strip 14 is used to support the connection between the hollow elastic pad 5 and the lower connecting strip 3 to ensure that the connection will not deform or break during deformation.

[0032] Through the above steps, when the PP material valve-specific sealing strip is used, after the upper clamp 2 is adapted to the mounting groove, the hollow elastic pad 5 and the upper clamp 2 work together to achieve a sealing effect. Due to its good elasticity, the hollow elastic pad 5 can fully contact the surface of the groove, playing a primary sealing role. The upper clamp 2 plays an auxiliary sealing role. With the cooperation of the two, the tightness of the seal is ensured. When encountering high-frequency vibration, the surface of the second anti-slip protrusion 9 is evenly distributed with serrated protrusions 10. The serrated protrusions 10 are used to increase friction. The second anti-slip protrusion 9 plays a primary anti-slip role, and the first anti-slip protrusion 4 plays an auxiliary anti-slip role, thereby ensuring that the main body 1 of the sealing strip will not detach from the groove.
