AI Technical Summary
The connection strength of existing mushroom-shaped hook-and-loop fasteners gradually decreases with repeated use, and the port connection is prone to loosening. Existing devices do not have the connection strength of a tight-fitting protective structure. In the existing technology, the connection strength is low, and the connection strength of existing devices is low and easily reduced, affecting the service life.
It adopts a design with magnetic sheets and an adsorption membrane. The magnetic sheets adhere to the end face of the strap to form a tight connection, which enhances the connection strength. The mushroom-shaped adsorption port and the internal cavity design form an adsorption function similar to a suction cup structure, which further enhances the connection strength.
The connection strength of the mushroom-shaped hook and loop fastener has been improved, reducing the possibility of deformation and damage to the mushroom mechanism after repeated tearing and fastening, thus ensuring the stability and service life of the connection.
