[0021] Compared with the prior art, the Velcro strip with back adhesive provided by the present application has the following advantages:1. This adhesive-backed hook and loop fastener, by attaching release paper to the surface of the adhesive layer, can cover the adhesive layer and prevent the adhesive layer from contacting dust in the air. At the same time, the mounting strip also covers both sides of the hook and loop fastener, which can block the sides of the adhesive layer, thereby preventing dust from entering the gap between the release paper and the sides of the adhesive layer. It can effectively prevent dust from entering the edges of the adhesive layer. The mounting strip is engaged in the mounting groove, so that when the release paper expands, the mounting strip can cooperate with the mounting groove to prevent the edges of the release paper from lifting up, and also prevent the release paper from separating from the surface of the adhesive layer when it shrinks.

[0022] 2. The adhesive-backed hook and loop fastener, with its added installation strip that works in conjunction with the release paper, can seal the adhesive layer and lock in moisture, preventing the adhesive layer from losing moisture and shrinking.

[0033] The release paper 6 is attached to the surface of the glue layer 5, which can cover the glue layer 5 and avoid contact with dust in the air, and the mounting strip 8 is also covered on both sides of the Velcro, which can shield both sides of the glue layer 5, so as to avoid dust entering the gap between the release paper 6 and the glue layer 5, effectively prevent dust from entering the edge of the glue layer 5, and the mounting strip 8 is clamped in the mounting groove 9, so that the mounting strip 8 can cooperate with the mounting groove 9 when the release paper 6 expands, avoiding the edge of the release paper 6 from being raised, and preventing the release paper 6 from separating from the surface of the glue layer 5 when shrinking, and the mounting strip 8 cooperates with the release paper 6 to seal the glue layer 5, which can lock the water in the glue layer 5, so that the glue layer 5 is not easy to lose water and shrink, improving the dustproof effect of the release paper 6 on the glue layer 5, and improving the firmness of the glue layer 5.

[0034] Please refer to Figure 1 The upper surface and the lower surface of the first Velcro shell 1 and the second Velcro shell 2 are uniformly provided with a pulling belt 10, and the pulling belt 10 is flexible, and the pulling belt 10 is designed as a semi-ring, which can tear off the release paper 6 from the surface of the glue layer 5 by pulling the release paper 6, so as to avoid tearing the release paper 6 due to the dense adhesion between the release paper 6 and the outer side of the glue layer 5.

[0035] Please refer to Figure 2 The mounting strip 8 is made of natural rubber compression molding, please refer to Figure 3 The inner diameter of the mounting groove 9 is larger than the volume of the mounting strip 8, and the mounting strip 8 can be clamped in the mounting groove 9 by pressing the mounting strip 8 when installing.

[0036] Please refer to Figure 2 The dustproof belt 7 is made of rubber and heated and solidified, and the dustproof belt 7 is connected to both sides of the release paper 6 by hot melt glue through high temperature, so that the dustproof belt 7 and the release paper 6 can be designed as one body, which is convenient for processing the dustproof belt 7.

[0037] Please refer to Figure 4 The middle part of the first hook-and-loop fastener shell 1 and the second hook-and-loop fastener shell 2 is provided with a base material layer 11, and the glue layer 5 is applied to the surface of the base material layer 11. The base material layer 11 is made of nylon material, so that the hook-and-loop fastener has strong transverse tensile force and tight bite characteristics.

[0038] The lower surface of the base material layer 11 is provided with an elastic layer 12, and the lower surface of the elastic layer 12 is provided with a mounting layer 13. The hook surface 3 is mounted on the surface of the mounting layer 13 of the first hook-and-loop fastener shell 1, and the pile surface 4 is mounted on the surface of the mounting layer 13 of the second hook-and-loop fastener shell 2.

[0039] The base material layer 11, the elastic layer 12 and the mounting layer 13 are connected by pressure-sensitive adhesive through high temperature and high pressure pressing. The elastic layer 12 is made of rubber material, which improves the flexibility of the hook-and-loop fastener. The mounting layer 13 is also made of nylon material, which further improves the transverse tensile force of the hook-and-loop fastener.

[0040] The working process of the device is as follows: first, the release paper 6 is attached to the surface of the glue layer 5, which can cover the glue layer 5 and avoid contact with dust in the air. At the same time, the installation strip 8 will also cover both sides of the hook-and-loop fastener, which can shield both sides of the glue layer 5, so as to avoid dust entering the gap between the release paper 6 and the two sides of the glue layer 5, and effectively prevent dust from entering the edge of the glue layer 5. The installation strip 8 is clamped in the installation groove 9, so that when the release paper 6 expands, the installation strip 8 can cooperate with the installation groove 9 to prevent the edge of the release paper 6 from lifting, and also prevent the release paper 6 from separating from the surface of the glue layer 5 when it shrinks. Then, the installation strip 8 cooperates with the release paper 6 to seal the glue layer 5, which can lock the water in the glue layer 5 and prevent it from shrinking due to loss of moisture. This improves the dustproof effect of the release paper 6 on the glue layer 5 and also improves the firmness of the glue layer 5. Finally, when the release paper 6 is removed, only the release paper 6 needs to be pulled by the pulling belt 10, and the release paper 6 can be torn off the surface of the glue layer 5. This avoids the difficulty of tearing the release paper 6 due to the dense adhesion between the release paper 6 and the outside of the glue layer 5. Since the installation strip 8 is made of natural rubber compression molding, the installation strip 8 will separate from the installation groove 9 when the release paper 6 is torn off, which makes it easy for the user to tear off the release paper 6. The dustproof belt 7 is made of rubber and is heated and solidified, so that the dustproof belt 7 and the release paper 6 can be designed as one piece, which facilitates the processing of the dustproof belt 7.
