Description

Technical Field

[0001] This utility model application relates to the field of sealing strip technology, specifically a non-deformable sealing strip for logistics containers. Background Technology

[0002] Container sealing strips are a type of sealing material used for the door frames of shipping containers. They are mainly used to ensure the airtightness of the container and prevent goods from being affected by the external environment during transportation. They have functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation, and can protect the safety of the goods inside the container. They are usually made of materials such as rubber and plastic and are widely used in various types of containers.

[0003] Existing container sealing strips are mostly fixed inside the container door frame during use. However, since containers are mostly stacked during transportation, the sealing strips are easily deformed due to stress during transportation and handling, or the sealing strips themselves may deform during transportation. This reduces the tightness of the sealing strips when installed against the container door frame, thereby reducing the sealing performance of the sealing strips during use. Summary of the Invention

[0004] To address the problem that existing logistics container sealing strips are prone to deformation during use, leading to reduced sealing performance, this invention provides a logistics container sealing strip that is less prone to deformation, thus solving the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A non-deformable sealing strip for logistics containers includes a sealing strip partition. Several sealing side pieces are symmetrically fixed at the upper and lower ends of the sealing strip partition. Several positioning steel wires are embedded and fixed at equal intervals inside each sealing side piece. Several positioning strips are embedded and fixed at equal intervals inside the sealing strip partition. Several positioning steel wires are embedded and fixed inside the sealing strip partition or sealing side piece between two adjacent positioning steel wires and positioning strips.

[0007] Furthermore, the sealing side plate includes an elastic rubber sleeve, a heat-insulating rubber sleeve, and a rigid support rubber sleeve. The outer surface of the positioning steel wire is wrapped and fixed with an elastic rubber sleeve, the outer surface of the elastic rubber sleeve is wrapped and fixed with a heat-insulating rubber sleeve, and the outer surface of the heat-insulating rubber sleeve is wrapped and fixed with a rigid support rubber sleeve.

[0008] Furthermore, the material of the sealing strip partition is the same as that of the sealing side piece, the thickness of the elastic rubber sleeve is less than the thickness of the heat insulation rubber sleeve, and the thickness of the heat insulation rubber sleeve is less than the thickness of the rigid support rubber sleeve.

[0009] Furthermore, the length of each of the positioning steel wires is less than the length of the sealing side piece, and the end of each of the sealing side pieces away from the sealing strip is set to be arc-shaped.

[0010] Furthermore, the thickness of each of the positioning strips and positioning wires is less than the thickness of the sealing strip partition, and the thickness of each of the positioning wires is less than the thickness of the sealing side piece.

[0011] Furthermore, a fireproof rubber sleeve is fixedly wrapped around the outer surface of the rigid support rubber sleeve, and a wear-resistant and corrosion-resistant rubber is fixedly wrapped around the outer surface of the fireproof rubber sleeve. The wear-resistant and corrosion-resistant rubber is coated with an anti-corrosion and fire-resistant coating.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the internal positioning steel wire and positioning strip provide support, allowing the sealing strip to reset itself during operation and after deformation, ensuring the tightness of the sealing strip's fit with the door frame. This solves the problem that existing logistics container sealing strips are prone to deformation during use, leading to reduced sealing performance. It also prevents the sealing strip from becoming misfit due to deformation after transportation or compression, thus avoiding reduced sealing performance caused by misfitting.

[0014] 2. In this utility model, the rigid support rubber sleeve inside the sealing strip can further provide support to the rubber strip during use. At the same time, the elastic rubber sleeve can protect the positioning steel wire, and the outer fireproof and corrosion-resistant rubber sleeve can improve the service life of the sealing strip.

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A non-deformable sealing strip for logistics containers includes a sealing strip partition 1. Several sealing side pieces 2 are symmetrically fixed at both the upper and lower ends of the sealing strip partition 1. Several positioning steel wires 3 are equidistantly embedded inside each sealing side piece 2. The length of each positioning steel wire 3 is less than the length of the sealing side piece 2. The end of each sealing side piece 2 away from the sealing strip partition 1 is arc-shaped. Several positioning strips 4 are equidistantly embedded inside the sealing strip partition 1. Several positioning steel wires 5 are embedded between adjacent positioning steel wires 3 and 4 in either the sealing strip partition 1 or the sealing side piece 2. The thickness of each positioning strip 4 and positioning steel wire 5 is less than the thickness of the sealing strip partition 1, and the thickness of each positioning steel wire 3 and positioning steel wire 5 is less than the thickness of the sealing side piece 2.

[0022] Specifically, when the sealing strip spacer 1 or the sealing side piece 2 deforms, when the sealing strip spacer 1 and the sealing side piece 2 are fitted onto the container door frame, the sealing strip spacer 1 and the sealing side piece 2 are pressed down so that the sealing strip spacer 1 and the sealing side piece 2 are tightly fitted to the door frame under the support of positioning steel wire 1 3 and positioning steel wire 2 5. At the same time, under the support of positioning strip 4, the sealing strip spacer 1 can maintain stability in length, avoiding the sealing strip spacer 1 from shrinking or loosening due to environmental factors such as long-term exposure to sunlight, thereby ensuring the stability of the sealing strip spacer 1 after it is fitted.

[0023] As an optimized solution, the sealing side plate 2 includes an elastic rubber sleeve 21, a heat-insulating rubber sleeve 22, and a rigid support rubber sleeve 23. The outer surface of the positioning steel wire 3 is wrapped and fixed with the elastic rubber sleeve 21, the outer surface of the elastic rubber sleeve 21 is wrapped and fixed with the heat-insulating rubber sleeve 22, and the outer surface of the heat-insulating rubber sleeve 22 is wrapped and fixed with the rigid support rubber sleeve 23. The material of the sealing strip spacer 1 is the same as that of the sealing side plate 2. The thickness of the elastic rubber sleeve 21 is less than the thickness of the heat-insulating rubber sleeve 22, the thickness of the heat-insulating rubber sleeve 22 is less than the thickness of the rigid support rubber sleeve 23, the outer surface of the rigid support rubber sleeve 23 is wrapped and fixed with a fireproof rubber sleeve 24, the outer surface of the fireproof rubber sleeve 24 is wrapped and fixed with a wear-resistant and corrosion-resistant rubber 25, and the outer surface of the wear-resistant and corrosion-resistant rubber 25 is coated with an anti-corrosion and fire-resistant coating 26.

[0024] Specifically, when the sealing strip spacer 1 and the sealing side plate 2 are in normal use, the elastic rubber sleeve 21 can protect the positioning steel wire 1 3, positioning strip 4 or positioning steel wire 2 5, the heat insulation rubber sleeve 22 and the fireproof rubber sleeve 24 can improve the fireproof and corrosion-resistant performance of the sealing strip spacer 1 and the sealing side plate 2, the rigid support rubber sleeve 23 can further support the sealing strip spacer 1 and the sealing side plate 2, and with the protection of wear-resistant and corrosion-resistant rubber 25 and corrosion-resistant and fire-resistant coating 26, the service life of the sealing strip spacer 1 is improved.
