Problems solved by technology

[0003] However, the sealant strips used on construction machinery are often opened and closed too much, such as forklifts, which cause the sealant strips to age and wear aggravated by opening and closing many times throughout the year, resulting in a greatly reduced overall sealing effect, especially in mosquitoes. If night work is carried out in many areas, the sealing effect may be poor due to the aging and wear of the sealing rubber strip, which may cause mosquitoes to penetrate into the car and interfere with the driver, resulting in difficulty and danger of night work; accordingly, the present invention proposes sealant strip

Abstract

The invention belongs to the technical field of sealing accessories, in particular relates to a sealing rubber strip comprising a main body and a fixing groove. The cross section of the main body is annular. A set of partition plates are arranged inside the main body, and a connecting block is arranged below the main body. The fixing groove is arranged in the middle portion of the connecting block, and the fixing groove is used for fixing the main body on edgings. The partition plates are elastically arranged, and the middle portions of the partition plates are all provided with interval cavities. An auxiliary sealing unit is arranged inside each interval cavity, and the auxiliary sealing unit is used for auxiliary support of the interior of the main body. Each auxiliary sealing unit comprises two symmetric semi-circular plates. Both the semi-circular arc plates are fixedly connected to the inner wall of the main body. The middle portions of each two adjacent semi-circular arc plates are in contact with each other. The invention achieves a better sealing effect by the internal auxiliary sealing units and supporting components, and reduces the problem that the sealing rubber strip wears too much and loses the elastic force, thereby enhancing the overall sealing property of the vehicle and improving the safety of night work.

Description

technical field [0001] The invention belongs to the technical field of sealing fittings, in particular to a sealing rubber strip. Background technique [0002] There are three kinds of rubber materials for automobile sealing strips: compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. The rubber of the sealing strip is mostly made of ethylene-propylene-diene monomer (EPDM) that is resistant to aging, low temperature, water vapor, and chemical corrosion, especially ozone aging. EPDM can be compounded with steel belt, steel wire braided belt, TPE, flannelette, flocking, PU coating, silicone coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction and anti Grinding and decorative effect. In general, EPDM sealing strips can be used stably for more than ten years. Chloroprene rubber (CR) with good ozone resistance and good aging resistance can also be selected. Considering the techni...
