Technical Field

[0001] This utility model relates to the field of sealing strip technology, specifically a wear-resistant silicone foam sealing strip. Background Technology

[0002] As an important material used to seal gaps between objects, sealing strips are commonly made of materials such as rubber, silicone, and plastic. A proper sealing strip performs multiple key functions, including sealing and waterproofing, sound insulation and noise reduction, and cushioning and shock absorption. Sealing strips are widely used in numerous fields such as the automotive, construction, electronics, and machinery manufacturing industries, playing an indispensable role in each. They significantly improve product performance and quality, bringing great convenience to people's lives and work. When selecting and using sealing strips, it is essential to carefully choose the appropriate material and specifications according to actual needs and ensure correct installation. Only in this way can the sealing effect be fully guaranteed.

[0003] Existing silicone foam sealing strips have many significant advantages. They have excellent sealing performance, effectively blocking the intrusion of dust, moisture and noise. At the same time, they are highly flexible and can easily adapt to sealing parts of different shapes and sizes. They are also very easy to install, and can fit tightly to various complex surfaces to ensure the integrity of the seal. In addition, when subjected to external pressure or impact, silicone foam sealing strips can play a full role in buffering, effectively protecting the sealed object from damage.

[0004] However, through actual use, it has been found that this type of sealing strip is easily damaged by external objects during use, which affects normal use. Therefore, a wear-resistant silicone foam sealing strip is proposed. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a wear-resistant silicone foam sealing strip to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant silicone foam sealing strip, comprising a sealing strip body, a PVC plate installed at the end of the sealing strip body, and a cavity for buffering inside the sealing strip body, an arc-shaped plate installed on the side wall of the sealing strip body, and a buffer component installed on the side wall of the arc-shaped plate, and a placement groove corresponding to the buffer component is provided on the side wall of the sealing strip body.

[0007] By adopting the above technical solutions, the cavity design reduces wear on the sealing strip body when the bottom of the sealing strip is compressed. The PVC board design also reduces wear inside the sealing strip body. The curved plate and buffer design provide cushioning when the side wall of the sealing strip body is compressed, thereby reducing wear. These designs maximize the wear resistance of the sealing strip body.

[0008] Furthermore, the cavity is located inside the bottom end of the sealing strip body, and the length of the cavity corresponds to the length of the sealing strip body.

[0009] By adopting the above technical solution, the bottom end of the sealing strip body can be less worn, and the service life of the sealing strip body can be increased.

[0010] Furthermore, two sets of placement grooves are provided on the side wall of the sealing strip body, and the height of the placement grooves corresponds to the diameter and length of the buffer component.

[0011] By adopting the above technical solution, the shock absorption and force relief effect of the buffer component on the sealing strip body is maximized, thereby increasing the wear resistance of the sealing strip body.

[0012] Furthermore, the buffer is fixedly installed between the placement groove and the arc-shaped plate, and the buffer is installed at equal intervals inside the placement groove, and the buffer is designed in a circular shape.

[0013] By adopting the above technical solution, the sealing strip body can be shock-absorbing and stress-relieving, so that the stress is evenly distributed, thereby increasing the wear resistance of the side walls of the sealing strip body.

[0014] Furthermore, the top of the PVC board is level with the top of the sealing strip body, and one corner of the PVC board is designed at an angle.

[0015] By adopting the above technical solution, the interior of the sealing strip body can be protected in all aspects, and the installation of the sealing strip body is more convenient.

[0016] Furthermore, two sets of the arc-shaped plates are installed on the side wall of the sealing strip body, and the arc-shaped plates are bent away from the sealing strip body.

[0017] By adopting the above technical solution, the wear and tear on the main body of the sealing strip is minimized.

[0018] Furthermore, the sealing strip body has a U-shaped design, and one end of the sealing strip body has a beveled corner design.

[0019] By adopting the above technical solution, the sealing strip body can be integrated with the bottom of the door during installation, making installation more convenient.

[0020] In summary, the present invention has the following main advantages:

[0021] This utility model incorporates a PVC board, a cavity, a buffer, and an arc-shaped plate. When using the sealing strip, the angled end is inserted under the door and pushed until it makes tight contact with the door seam. During daily door opening and closing, even if small particles on the ground may cause wear to the sealing strip, the ingenious design of the cavity provides excellent cushioning, greatly reducing wear. Furthermore, because the sealing strip fits tightly against the door, it suffers almost no wear under the strong protection of the PVC board. When the sealing strip is compressed, the unique design of the buffer and arc-shaped plate effectively absorbs and dissipates the force, further enhancing its wear resistance and allowing it to exhibit wear-resistant performance in various complex usage environments.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A wear-resistant silicone foam sealing strip, such as Figure 1 - Figure 4As shown, the device includes a sealing strip body 1, with a PVC plate 4 installed at the end of the sealing strip body 1 to reduce wear inside the sealing strip body 1. The sealing strip body 1 also has a buffer cavity 101 inside, which can relieve pressure when the bottom of the sealing strip body 1 is compressed, thereby reducing wear. An arc-shaped plate 3 is installed on the side wall of the sealing strip body 1, and a buffer element 2 is installed on the side wall of the arc-shaped plate 3. A placement groove 102 corresponding to the buffer element 2 is opened on the side wall of the sealing strip body 1. When both sides of the sealing strip body 1 are compressed, the arc-shaped plate 3 and the buffer element 2 can buffer the external force, thereby reducing wear on the sealing strip body 1.

[0030] Please see Figure 1 , Figure 2 and Figure 4 The cavity 101 is located inside the bottom of the sealing strip body 1, and the length of the cavity 101 corresponds to the length of the sealing strip body 1, which can provide good protection for the bottom of the sealing strip body 1.

[0031] Please see Figure 1 - Figure 4 The placement groove 102 is provided in two sets on the side wall of the sealing strip body 1, and the height of the placement groove 102 corresponds to the diameter and length of the buffer 2, so that the shock absorption effect of the buffer 2 on the sealing strip body 1 is maximized.

[0032] Please see Figure 2 The buffer 2 is fixedly installed between the placement groove 102 and the arc plate 3. The buffer 2 is installed at equal intervals inside the placement groove 102 and has a circular design, which can make the shock absorption effect of the buffer 2 reach the best.

[0033] Please see Figure 1 , Figure 2 and Figure 4 The top of the PVC board 4 is flush with the top of the sealing strip body 1, which can protect the inside of the sealing strip body 1 and reduce wear. In addition, one end of the PVC board 4 is designed with an angled corner, which can guide the sealing strip body 1 during installation.

[0034] Please see Figure 1 - Figure 4 Two sets of arc-shaped plates 3 are installed on the side wall of the sealing strip body 1, which can protect both sides of the sealing strip body 1. The arc-shaped plates 3 are bent away from the sealing strip body 1, so that the sealing strip body 1 is subjected to the least amount of wear.

[0035] Please see Figure 1 - Figure 4 The sealing strip body 1 has a U-shaped design, and one end of the sealing strip body 1 has a beveled design, which allows the sealing strip body 1 to be combined with the bottom of the door during installation, and makes installation more convenient.

[0036] The working principle of this utility model is as follows: When using the sealing strip body 1, insert one end with the corner design under the door, and then slowly push it until the end of the sealing strip body 1 is tightly fitted with the door seam. During this pushing process, under normal circumstances, the inside of the sealing strip body 1 will rub against the bottom of the door. However, due to the design of the PVC board 4, there will be no signs of wear inside the sealing strip body 1. The PVC board 4 firmly protects the inside of the sealing strip body 1, preventing it from being worn by contact with the bottom of the door. When people perform daily door opening and closing operations, even if there are some small particles on the ground... These small particles, which would normally cause wear on the sealing strip body 1, are fortunately mitigated by the carefully designed cavity 101. The cavity 101 provides excellent cushioning when the sealing strip body 1 is affected by small particles from the ground. Upon contact with the small particles, the cavity 101 absorbs and disperses the impact force, significantly reducing wear. Furthermore, when people enter or exit doors or drag heavy objects, the sealing strip body 1 is inevitably squeezed, which usually leads to wear. However, at this time, once the sealing strip body 1... When subjected to force, the arc plate 3 will quickly move inward, thereby squeezing the buffer 2. The buffer 2 will deform after being squeezed. This deformation process is like an energy absorber, converting the external force into its own deformation energy, thereby greatly reducing the pressure transmitted to the sealing strip body 1 and further reducing the wear of the sealing strip body 1. These carefully designed components work together to achieve the best wear resistance of the sealing strip body 1. Whether it is frequent opening and closing of doors, accidental interference from small particles on the ground, or the squeezing of heavy objects, the sealing strip body 1 can cope with these conditions with ease and always maintain a good condition, providing users with long-lasting and reliable sealing performance.
