Description

Technical Field

[0001] This utility model relates to the field of automotive sealing steel strip application technology, and in particular to a flexible and bendable composite steel strip. Background Technology

[0002] Composite sealing steel strips effectively fill gaps, preventing the leakage of air, moisture, dust, and other substances, achieving a good sealing effect. Simultaneously, due to the presence of the steel strip, the composite sealing steel strip has high tensile and compressive strength, making it resistant to tearing and breakage. This allows it to maintain good performance over long-term use, reducing replacement frequency and maintenance costs.

[0003] Existing composite steel strips typically have foam layers on the top or sides during manufacturing, limiting their installation to specific locations and restricting their use. This lack of comprehensive protection reduces their lifespan. Furthermore, the internal connectors of traditional steel strips are prone to detachment over time. Therefore, this invention proposes a flexible, bendable composite steel strip. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a flexible and bendable composite steel strip. By surrounding the rubber strip with a foam cotton layer, the composite steel strip can be protected in all directions after installation, thereby improving the service life of the entire composite steel strip. At the same time, the rubber strip has a relatively staggered anti-slip structure inside, which can keep the entire steel strip stable after being snapped together and prevent it from falling off.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a flexible and bendable composite steel strip is provided, including a rubber strip, multiple U-shaped steel frames installed inside the rubber strip, and a foam layer. The multiple steel frames are arranged at equal intervals, and the foam layer is arranged in a C-shape and surrounds the outside of the rubber strip. The two ends of the foam layer are respectively fixed to the two side walls of the rubber strip near the end face, and are arranged in a smooth arc transition.

[0006] The present invention is further configured such that: the rubber strip is U-shaped as a whole, and reinforced chamfered parts are symmetrically provided at the inner corners.

[0007] The above technical solution facilitates the installation of rubber strips by utilizing the reinforced chamfered portion to prevent cracking and damage at the inner corners when the rubber strips are stretched, thereby enhancing the strength and service life of the rubber strips.

[0008] The present invention is further configured such that: an anti-slip extrusion block is fixedly connected to the middle position of the inner side wall of the rubber strip, and the cross section of the anti-slip extrusion block is arranged in an isosceles trapezoidal shape.

[0009] The above technical solution utilizes anti-slip compression blocks to stably compress the rubber strip onto the vehicle body, thus ensuring the rubber strip is securely fixed.

[0010] The present invention is further configured such that: an opening is provided in the middle of the side wall of the anti-slip extrusion block, and the opening is narrowed from the inside to the outside.

[0011] The above technical solution allows the anti-slip compression block to elastically return to its original position after being squeezed, and to be stably squeezed onto the vehicle body, thus achieving compression fixation.

[0012] The present invention is further configured such that the top and bottom corners of the inner sidewall of the opening are both provided with arc-shaped bends.

[0013] The above technical solution allows the opening to bend flexibly under the action of the arc-shaped bend when installing the rubber strip, thus avoiding damage to the inside of the opening.

[0014] The present invention is further configured such that: the top and bottom of the anti-slip extrusion block are provided with extrusion inclined blocks, and the end faces of the two extrusion inclined blocks are both arc-shaped.

[0015] The above technical solution facilitates the stable and quick installation of the rubber strip on the vehicle body sealing edge by squeezing the inclined block during installation.

[0016] The present invention is further configured such that: two anti-slip auxiliary blocks are provided on the inner side wall of the rubber strip away from the anti-slip extrusion block, and the two anti-slip auxiliary blocks are respectively placed on the two side walls of the protective extrusion block, and the two side walls of the two anti-slip auxiliary blocks are both set as inclined surfaces.

[0017] The above technical solution utilizes two protective auxiliary blocks in conjunction with an anti-slip compression block on the other side to stably install and fix the rubber strip.

[0018] The present invention is further configured such that the sidewalls of the two anti-slip auxiliary blocks are provided with anti-slip serrations, and the end faces of the anti-slip serrations are inclined towards the inner top of the rubber strip.

[0019] The above technical solution facilitates the use of multiple anti-slip serrations to secure the sealed position of the vehicle after installation, preventing it from falling off during long-term use.

[0020] The present invention is further configured such that: the inner arc wall of the foam layer is provided with a plurality of connecting parts at equal intervals, and is fixedly connected to the outer wall of the rubber strip through the connecting parts.

[0021] The above technical solution facilitates the use of multiple connecting parts to fix the position of the external foam, ensuring its stability under pressure.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. The flexible and bendable composite steel strip proposed in this utility model provides all-round protection for the installed composite steel strip by surrounding the rubber strip with a foam cotton layer, thereby improving the service life of the entire composite steel strip.

[0024] 2. The flexible and bendable composite steel strip proposed in this utility model has a relatively staggered anti-slip structure set inside the rubber strip, which makes the entire steel strip stable after being snapped on and prevents it from falling off. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2As shown, a flexible and bendable composite steel strip includes a rubber strip 1. The rubber strip 1 is U-shaped, and reinforced chamfered portions 11 are symmetrically arranged at the inner corners. When the rubber strip 1 is installed, the reinforced chamfered portions 11 can prevent the inner corners from cracking and being damaged when the rubber strip 1 is stretched, thereby enhancing the strength and service life of the rubber strip 1. An anti-slip compression block 12 is fixedly connected to the middle of the inner side wall of the rubber strip 1. The cross-section of the anti-slip compression block 12 is an isosceles trapezoid. The anti-slip compression block 12 can stably compress the rubber strip 1 onto the vehicle body, so that the rubber strip 1 is stably fixed.

[0033] like Figure 4 As shown, the anti-slip compression block 12 has an opening 121 in the middle of its side wall, and the opening 121 is tapered from the inside to the outside. This allows the compressed anti-slip compression block 12 to elastically return to its original position and be stably pressed onto the vehicle body for compression fixation. The top and bottom corners of the inner side wall of the opening 121 are both provided with arc-shaped bends 122, which allow the opening 121 to be flexibly bent under the action of the arc-shaped bends 122 when the rubber strip 1 is installed, avoiding damage to the inside of the opening 121. The top and bottom of the anti-slip compression block 12 are provided with compression wedges 123, and the end faces of the two compression wedges 123 are both arc-shaped, which allows the rubber strip 1 to be stably engaged and installed when it is installed, so that the rubber strip 1 can be stably and quickly installed on the sealing edge of the vehicle body.

[0034] like Figure 5 As shown, two anti-slip auxiliary blocks 13 are provided on the inner side wall of the rubber strip 1 away from the anti-slip extrusion block 12, and the two anti-slip auxiliary blocks 13 are respectively placed on the two side walls of the protective extrusion block 12. At the same time, the two side walls of the two anti-slip auxiliary blocks 13 are both set as inclined surfaces 131. By using the two protective auxiliary blocks 13 in conjunction with the anti-slip extrusion block 12 on the other side, the rubber strip 1 can be stably installed and fixed. The side walls of the two anti-slip auxiliary blocks 13 are provided with anti-slip serrations 132, and the end faces of the anti-slip serrations 132 are inclined towards the inner top of the rubber strip 1, so as to use multiple anti-slip serrations 132 to fix the sealing position of the vehicle after installation and prevent it from falling off during long-term use.

[0035] like Figure 3As shown, multiple U-shaped steel frames 2 and foam layers 3 are installed inside the rubber strip 1. The steel frames 2 are arranged at equal intervals, and the foam layers 3 are arranged in a C-shape and surround the outside of the rubber strip 1. The two ends of the foam layers 3 are fixed to the two side walls of the rubber strip 1 near the end face, and are arranged in a smooth arc transition. Multiple connecting parts 31 are arranged at equal intervals on the inner arc wall of the foam layers 3, and are fixedly connected to the outer wall of the rubber strip 1 through the connecting parts 31. This makes it easy to use multiple connecting parts 31 to fix the position of the outer foam 3, so that it remains stable during the pressure process.

[0036] In use, the rubber strip 1 is installed on the vehicle body sealing edge with its opening direction, so that the vehicle body sealing edge squeezes the anti-slip compression block 12 and the anti-slip auxiliary block 13, thereby opening the rubber strip 1 and the steel frame 2. After continuous insertion, the anti-slip compression block 12 and the anti-slip auxiliary block 13 can be tightly fitted to the vehicle body sealing edge by utilizing the restoring elasticity of the steel frame 2. Under the action of multiple anti-slip serrations 132, the installation of the rubber strip 1 is stable, and the external foam 3 can improve the protective sealing performance of the entire steel strip.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
