Description

Technical Field

[0001] This utility model relates to the field of container sealing strip technology, and specifically discloses an easy-to-install container sealing strip. Background Technology

[0002] Sealing strips are products used to seal something, making it difficult to open. They serve 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. Since the 1980s, sealing strips have been applied to 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.

[0003] Container sealing strips are mainly used for sealing the door frames of container cargo containers. According to their function, they can be divided into two categories: weather sealing strips (used for general cargo containers) and airtight sealing strips (used for insulated containers).

[0004] Traditional container sealing strip installation requires tools or multiple people to work together. Rigid sealing strips need to be pressed hard to be embedded in the groove, which is labor-intensive. Moreover, once embedded in the groove, they are easy to fall out, making installation inconvenient. In addition, existing sealing strips are made of a single rubber material, which has low tensile strength and is prone to breakage and damage. Utility Model Content

[0005] This utility model proposes an easy-to-install container sealing strip, which forms a double fixation through the mechanical interlocking of the elastic ribs and the bonding of pressure-sensitive adhesive, enabling quick manual installation and preventing vibration-induced detachment. The arc-shaped sealing part adaptively fills the door gap after being compressed, and the internal anti-tensile ribs ensure long-term sealing stability.

[0006] This utility model is achieved as follows: an easy-to-install container sealing strip, comprising:

[0007] The mounting part has a rectangular cross-section and two inclined elastic clips are fixedly connected to both side walls. A pressure-sensitive adhesive layer is provided at the bottom of the mounting part.

[0008] The sealing part is fixedly connected to the top of the mounting part. The sealing part has an arc-shaped cross-section and multiple wear-resistant ribs are fixedly connected to the arc-shaped surface. Multiple tensile ribs are provided inside the sealing part along the length direction.

[0009] As a preferred embodiment of this utility model of an easy-to-install container sealing strip, the upper surface of the elastic locking ridge is provided with anti-slip texture.

[0010] As a preferred embodiment of this utility model of an easy-to-install container sealing strip, the lower end face of the pressure-sensitive adhesive layer is provided with a peelable protective film.

[0011] As a preferred embodiment of this utility model of an easy-to-install container sealing strip, the wear-resistant ribs are hollow semi-circular structures, and multiple wear-resistant ribs form a wavy structure.

[0012] As a preferred embodiment of this utility model of an easy-to-install container sealing strip, the tensile reinforcement is a steel wire rope.

[0013] As a preferred embodiment of this utility model of an easy-to-install container sealing strip, the mounting part, the elastic retaining rib, the sealing part, and the wear-resistant rib are all made of styrene-butadiene rubber.

[0014] The beneficial effects of this utility model are:

[0015] This invention achieves dual fixation through the mechanical interlocking of elastic ribs and the bonding of pressure-sensitive adhesive, enabling quick manual installation and preventing vibration-induced detachment. The arc-shaped sealing part adaptively fills the door gap after being compressed, and the internal tensile ribs ensure long-term sealing stability. The hollow wear-resistant rib structure effectively buffers friction and impact, reduces wear on the sealing part, and extends service life. The overall structure is significantly superior to traditional sealing strips in terms of tool-free installation, tensile deformation resistance, and wear resistance, making it especially suitable for container environments with frequent opening and closing.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-2 An easy-to-install container sealing strip, comprising:

[0022] Mounting part 1 has a rectangular cross section and two inclined elastic clips 2 are fixedly connected to both side walls. A pressure-sensitive adhesive layer 3 is provided at the bottom of mounting part 1.

[0023] The sealing part 4 is fixedly connected to the top of the mounting part 1. The cross-section of the sealing part 4 is arc-shaped and multiple wear-resistant ribs 5 are fixedly connected to the arc-shaped surface. Multiple tensile ribs 6 are provided inside the sealing part 4 along the length direction.

[0024] In this embodiment: When the elastic locking ribs 2 on both sides of the mounting part 1 are inserted into the container slot, they are squeezed by the slot wall and undergo inward elastic deformation. When fully inserted, the elastic locking ribs 2 rebound outward by the elastic recovery force of the styrene-butadiene rubber, forming a multi-point engagement with the inner wall of the slot, generating a mechanical anti-loosening force. After the pressure-sensitive adhesive layer 3 at the bottom of the mounting part 1 contacts the bottom surface of the slot, it fills the gap between the slot and the sealing strip through instant adhesion, forming a secondary fixation to avoid loosening due to vibration. The arc-shaped sealing part 4 undergoes radial elastic deformation after being pressed, tightly fitting the edge of the container door seam to achieve self-adaptive filling. The wear-resistant ribs 5 are hollow semi-circular structures. When the sealing part 4 is subjected to friction and pressure, the multiple wear-resistant ribs 5 on the outside are first squeezed and deformed, effectively playing the role of anti-friction and shock absorption, thereby avoiding the sealing part 4 from being directly subjected to friction and improving wear resistance. Multiple tensile ribs 6 are provided along the length of the sealing part 4 to provide good tensile strength and prevent the sealing strip from plastic deformation or breakage due to container transportation vibration.

[0025] As a technical optimization of this utility model, the upper surface of the elastic rib 2 is provided with anti-slip texture 7.

[0026] In this embodiment, the upper surface of the elastic locking ridge 2 is provided with anti-slip texture 7, thereby increasing the friction between the elastic locking ridge 2 and the container slot wall.

[0027] As a technical optimization of this utility model, a peelable protective film 8 is provided on the lower end surface of the pressure-sensitive adhesive layer 3.

[0028] In this embodiment, a peelable protective film 8 is provided on the lower end face of the pressure-sensitive adhesive layer 3, which facilitates the isolation and protection of the pressure-sensitive adhesive layer 3 before use.

[0029] As a technical optimization of this utility model, the wear-resistant rib 5 is a hollow semi-circular structure, and multiple wear-resistant ribs 5 form a wave-shaped structure.

[0030] In this embodiment, the wear-resistant ribs 5 are hollow semi-circular structures. When the sealing part 4 is subjected to friction and compression, the multiple wear-resistant ribs 5 on the outside are first compressed and deformed, which effectively plays the role of anti-friction and shock absorption, thereby avoiding the sealing part 4 from being directly subjected to friction and improving wear resistance.

[0031] As a technical optimization of this utility model, the tensile reinforcement 6 is a steel wire rope.

[0032] In this embodiment: the tensile rib 6 is a steel wire rope with high tensile strength, which improves the overall tensile performance of the sealing strip, avoids breakage and damage, and extends its service life.

[0033] As a technical optimization of this utility model, the mounting part 1, the elastic retaining rib 2, the sealing part 4, and the wear-resistant rib 5 are all made of styrene-butadiene rubber.

[0034] In this embodiment: the mounting part 1, the elastic retaining rib 2, the sealing part 4, and the wear-resistant rib 5 are all made of styrene-butadiene rubber, which has high wear resistance, heat resistance, and low temperature resistance, thereby ensuring the strength of the sealing strip base and strong cold resistance, so that the sealing strip can be used for a long time in low temperature environment.

[0035] The working principle and usage process of this utility model are as follows: When the elastic locking ribs 2 on both sides of the installation part 1 are inserted into the container slot, they are squeezed by the slot wall and undergo inward elastic deformation. When fully inserted, the elastic locking ribs 2 rebound outward by relying on the elastic recovery force of styrene-butadiene rubber, forming a multi-point engagement with the inner wall of the slot, generating mechanical anti-loosening force. After the pressure-sensitive adhesive layer 3 at the bottom of the installation part 1 contacts the bottom surface of the slot, it fills the gap between the slot and the sealing strip through instant adhesion, forming a secondary fixation to avoid loosening caused by vibration. The arc-shaped sealing part 4 undergoes radial elastic deformation after being pressed, tightly fitting the edge of the container door seam to achieve self-adaptive filling. The wear-resistant ribs 5 are hollow semi-circular structures. When the sealing part 4 is subjected to friction and pressure, the multiple wear-resistant ribs 5 on the outside are first squeezed and deformed, effectively playing the role of anti-friction and shock absorption, thereby avoiding the sealing part 4 being directly subjected to friction and improving wear resistance. Multiple tensile ribs 6 are provided along the length of the sealing part 4 to provide good tensile strength and prevent the sealing strip from plastic deformation or breakage due to container transportation vibration.
