Description

Technical Field

[0001] This utility model belongs to the field of sealing strip technology, specifically relating to a novel waterproof polymer sealing strip. Background Technology

[0002] A sealing strip is a product used to seal something, making it difficult to open and serving functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Sealing strips are made of various materials including rubber, paper, metal, and plastic. They have been applied in various industries such as automobiles, doors and windows, cabinets, refrigerators, and containers. Based on the requirements of different industries, unique automotive sealing strips, mechanical sealing strips, and door and window sealing strips have been developed. Sealing strips can be classified according to cross-sectional shape, vulcanization method, application location and purpose, and materials used. They can be divided into solid products (round, square, flat cross-sectional shapes), hollow products, and metal-rubber composite products. PVC door and window sealing strips are a new generation of door and window sealing strips that have been widely used in recent years. They offer better corrosion resistance, weather resistance, noise reduction, and heat insulation compared to ordinary door and window sealing strips, and have a smooth surface. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber. Electrical cabinet sealing strips are made of EPDM rubber foam and compacted composite, which has good elasticity, resistance to compression deformation, aging, ozone, chemical action, and a wide operating temperature range. It plays a crucial role in various electrical cabinets. Currently, during the use of sealing strips, they are easily subjected to external compression. During the compression process, certain gaps will exist in the compressed part of the sealing strip, which can easily allow external water to enter the sealing strip, reducing the sealing effect and affecting the use of the sealing strip. Therefore, a new type of waterproof polymer sealing strip is needed. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a novel waterproof polymer sealing strip. This solves the problem that current sealing strips are easily subjected to external pressure during use, resulting in gaps in the compressed portion that allow external water to enter, reducing the sealing effect and affecting the strip's usability. Therefore, a novel waterproof polymer sealing strip is needed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel waterproof polymer sealing strip, comprising a sealing strip body, supporting protrusions fixedly installed on both sides of the inner wall of the sealing strip body, a sealing strip lip fixedly installed on the upper surface of the sealing strip body, a sealing and waterproof layer fixedly installed on the inner wall of the sealing strip lip, a water drainage groove formed on the upper surface of the sealing strip lip, a reinforcing screw fixedly installed on the inner wall of the sealing strip body, strong double-sided adhesive adhered to the lower surface of the sealing strip body, and anti-slip grooves formed on both sides of the sealing strip body.

[0005] Preferably, the number of the support protrusions is six, and they are divided into groups of three.

[0006] Preferably, the sealing and waterproof layer is provided with an EPDM rubber layer and a polyurethane layer inside, and the polyurethane layer is located on one side of the EPDM rubber layer.

[0007] Preferably, a release liner is provided on one side of the strong double-sided adhesive, and the surface of the release liner is provided with a usage mark.

[0008] Preferably, the top of the sealing strip lip is arc-shaped.

[0009] Preferably, several water drainage channels are provided.

[0010] Preferably, two work warning stickers are fixedly installed on the upper surface of the sealing strip lip.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The arc-shaped sealing lip at the top can relieve the pressure from compression, allowing the force to diffuse to both sides when the sealing strip body is subjected to compression. The sealing and waterproof layer composed of polyurethane and EPDM rubber layers has excellent seepage prevention, leakage prevention, and water-stopping effects. It is also corrosion-resistant, aging-resistant, and resistant to high and low temperatures, extending the service life of the sealing strip body. It adapts to natural expansion and contraction changes, enhancing the sealing and expansion water-stopping effect of the joint, thereby improving the sealing effect of the sealing strip.

[0021] Workers can use the release paper 8 by using the markings. After removing the release paper 8 from the strong double-sided adhesive 7, workers can then apply the strong double-sided adhesive 7 to the installation position of the sealing strip body 1. The strong double-sided adhesive 7 is used to install the sealing strip body 1, preventing it from falling off during use. After installation with the strong double-sided adhesive 7, when the sealing strip body 1 is subjected to pressure, the support protrusion 2 and the reinforcing screw 6 can strengthen the sealing strip body 1, preventing significant deformation under pressure. Simultaneously, the arc-shaped sealing lip 3 at the top can absorb the pressure, allowing the force to diffuse to both sides through the arc-shaped sealing lip 3 when the sealing strip body 1 is subjected to pressure. The sealing and waterproof layer 4, composed of polyurethane layer 402 and EPDM rubber layer 401, has good seepage prevention, leakage prevention, and water-stopping effects. It is also corrosion-resistant, aging-resistant, and resistant to high and low temperatures, extending the service life of the sealing strip body 1. It adapts to natural expansion and contraction changes, enhancing the sealing expansion and water-stopping effect of the joint, thereby improving the sealing effect of the sealing strip. The anti-slip groove 9 can provide anti-slip protection for both sides of the sealing strip body 1 during installation, strengthening the anti-slip properties of the sealing strip body 1. Several water drainage grooves 5 are used to guide water sources that come into contact with the sealing strip body 1 from the outside, allowing the water to be discharged through the water drainage grooves 5, preventing water from entering the sealing strip body 1. The work warning sticker 10 is used to warn and remind the workers installing the sealing strip body 1 to install the sealing strip body 1 properly.

[0022] In one aspect of this embodiment, six support protrusions 2 in groups of three are used to provide support and stability for the sealing strip body 1, preventing the sealing strip body 1 from easily breaking when it is squeezed.

[0023] In one aspect of this embodiment, the sealing and waterproof layer 4, composed of a polyurethane layer 402 and an EPDM rubber layer 401, has good seepage prevention, leakage prevention, and water-stopping effects. It is also corrosion-resistant, aging-resistant, and resistant to high and low temperatures, extending the service life of the sealing strip body 1. It adapts to natural expansion and contraction changes and enhances the sealing expansion and water-stopping effect of the joint.

[0024] In one aspect of this embodiment, the worker can use the release paper 8 by using the markings. After the worker removes the release paper 8 from the strong double-sided adhesive 7, the worker can contact the strong double-sided adhesive 7 with the installation position of the sealing strip body 1 and install the sealing strip body 1 by using the strong double-sided adhesive 7 to prevent the sealing strip body 1 from falling off during use.

[0025] In one aspect of this embodiment, the top arc-shaped sealing lip 3 can relieve the pressure from the extrusion, so that when the sealing strip body 1 is subjected to extrusion, the force will be diffused to both sides through the top arc-shaped sealing lip 3, preventing the extrusion force from being directly squeezed onto the sealing strip body 1.

[0026] In one aspect of this embodiment, the work warning sticker 10 serves as a warning and reminder to the workers installing the sealing strip body 1, alerting them to install the sealing strip body 1.

[0027] In one aspect of this embodiment, a plurality of water drainage channels 5 are used to guide water sources that come into contact with the sealing strip body 1 from the outside, so that the water sources are discharged through the water drainage channels 5 and prevent water sources from entering the sealing strip body 1.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
