Description

Technical Field

[0001] The utility model relates to the technical field of edge banding strips, in particular to a replaceable shield edge banding strip system. Background Art

[0002] In the modern military, law enforcement, and security fields, protective shields have become a vital piece of personal protective equipment, widely used in combat and on-duty missions by the military, armed police, and security personnel. The primary function of a protective shield is to provide effective protection against blast waves, pistol bullets, high-velocity fragments, and blunt force attacks such as clubs, thereby maximizing personal safety in hazardous environments. These shields are typically made of high-strength materials, and the shield's impact-facing surface is specially designed and reinforced to withstand a wide range of threats and possess excellent impact resistance. However, due to design considerations, the sides of the shield are relatively weak compared to the impact-facing surface, unable to provide the same level of protection and easily becoming a potential weak link.

[0003] To improve the overall performance of protective shields, especially to prevent foreign matter such as water and dust from entering the sides of the shield and reducing its protective capabilities, the traditional method is to bond rubber or PVC sealing strips to the sides of the shield to form an edge seal. This edge sealing design not only effectively seals the sides of the shield, preventing the intrusion of harmful external substances, but also improves the shield's durability to a certain extent. However, this method has exposed some limitations and potential safety hazards in actual use.

[0004] First, rubber or PVC sealing strips are typically installed using a one-time bonding process, which means that once installed, they are difficult to remove and reinstall without damaging them. Therefore, in practice, if the sealing strip is damaged by external impact, abrasion, or other factors, repairing or replacing it becomes extremely difficult. Furthermore, damaged rubber strips often leave a large amount of adhesive residue on the shield, which is difficult to completely remove without specialized tools and techniques. This can affect the adhesion of the new sealing strip and even further damage the shield structure.

[0005] During daily use and training, these issues often occur with protective shields. Especially during frequent combat drills and harsh environments, damaged seals can directly impact the shield's performance and weaken its ability to protect the user. Therefore, improving the shield's side sealing design to enhance its effectiveness and durability has become a critical challenge. Solving this problem would not only extend the shield's lifespan but also better protect the user's life in practical applications. Utility Model Content

The edge strip 2 is long and has a U-shaped cross section. The edge strip 2 is wrapped around the edge of the shield 1 by using its U-shaped structure.

[0035] The fixing base 3 is detachably connected to the shield 1 . The fixing base 3 is provided with a portion where the end and end of the edge strip 2 meet. Both the beginning and end of the edge strip 2 are detachably connected to the fixing base 3 .

[0036] In this embodiment, it should be noted that Figures 2 to 5 As shown, the fixing base 3 includes a connecting plate 5 and two vertical plates 6, and the two vertical plates 6 are respectively vertically arranged on both sides of the connecting plate 5 in the width direction;

[0037] At least two threaded holes 7 are provided on the vertical plate 6. The two threaded holes 7 are arranged in sequence along the length direction of the vertical plate 6. The threaded holes 7 pass through the vertical plate 6, and a bolt 4 is provided in the threaded hole 7. Specifically, the bolt 4 adopts a flat head bolt, and the length of the bolt 4 is 1.5 cm to 2 cm. During use, by adjusting the screw-in length of the bolt 4, it can adapt to shields 1 of different thicknesses, so that the fixing base can be tightly fixed on the shield 1 using the bolt 4.

[0038] Furthermore, the vertical plate 6 and the connecting plate 5 are an integrated structure, and the whole is injection-molded with polyethylene, and the distance between the two vertical plates 6 is 3 cm to 4 cm.

[0039] The technical effect achieved by this embodiment is that the edge banding 2 can be quickly removed and installed on the shield 1, giving the edge banding system extremely high adaptability and versatility, and can accommodate a variety of shield specifications and models. The user can quickly remove and reinstall the edge banding through simple operations, without the need for special tools or professional skills. This feature greatly reduces the maintenance time and cost of the protective shield, especially in intense conflict scenarios such as exercises, counter-terrorism, and warfare.

[0042] In this embodiment, the edge banding strip 2 is made of EPDM rubber, which has excellent ozone resistance, UV resistance, weather resistance and aging resistance, electrical insulation, chemical resistance and impact resistance; peroxide vulcanization treatment is used during the production process to further enhance its aging resistance and reduce compressive deformation; and a plurality of keels 8 are provided in the edge banding strip 2, and the plurality of keels 8 are arranged in sequence along the length direction of the edge banding strip 2.

[0043] In this embodiment, it should be noted that Figure 6 As shown, the keel 8 includes a bottom plate 9 and two side plates 10. The two side plates 10 are vertically arranged on both sides of the bottom plate 9 in the width direction. The bottom plate 9 and the side plates 10 are an integral structure. The side plates 10 are trapezoidal, and the bottom angle of the side plates 10 is 45 degrees. Two adjacent keels 8 abut each other. When in use, the rubber at the connection of the keels 8 can be cut with scissors to cut the corresponding length to adapt to shields of different sizes. At the same time, the rubber part of the adjacent two keels 8 can be trimmed with scissors to form an inverted triangular notch, realizing the 0-90 degree upward bending function of the edge banding, thereby adapting to shields of different shapes.

[0044] The edge strip 2 can be arranged along the edge of the shield, and then pressure is applied inward on both sides of the edge strip 2, so that the two wings containing the keel 8 tilt inward to form a fixed shape (such as Figure 8 , ensuring the shield's overall locking function. Furthermore, during use, the opening angles of the two side panels 10 of the keel 8 can be adjusted to accommodate shields of varying thicknesses. This design allows the edge banding 2 to be repeatedly disassembled and assembled according to the actual size of the shield without damaging the shield itself. This adjustable structural design gives the edge banding system extreme adaptability and versatility, allowing it to accommodate a wide variety of shield specifications and models.

[0045] Furthermore, a plurality of slots 11 are provided on the top of the side panel 10 along its length direction. The slots 11 are semicircular and are arranged at equal intervals. When in use, the slots 11 at both ends of the edge banding are exposed by trimming with scissors, and the slots 11 are used as hooks to hang them with the corresponding bolts 4 on the fixing seat 3 (such as Figure 7 As shown in the figure), the edge banding strips 2 can be connected end to end. After tightening the bolts 4, it can be ensured that the fixing base 3 will not be accidentally loosened during use, and the edge banding strips can be prevented from accidentally falling off when subjected to external force or vibration. This not only enhances the fixing effect of the edge banding strips 2, but also ensures the convenience, stability and reliability of the edge banding system in long-term use.
