Detailed Implementation

[0014] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a portable multi-functional PDA bag, including a bag body 1, a pen box 4 at the top of the bag body 1, a buckle 2 fixed on the bag body 1 corresponding to the position of the pen box 4, an elastic arm fixing unit 3 installed on the side of the bag body 1, a cap 6 connected to the opening of the bag body 1 by a connecting strap 5, a first magnetic connecting strip 7 fixed to the side of the cap 6, and a second magnetic connecting strip 8 fixed to the opening of the bag body 1. The second magnetic connecting strip 8 is magnetically connected to the first magnetic connecting strip 7. The second magnetic connecting strip 8 and the first magnetic connecting strip 7 can be N52 neodymium iron boron magnets, and are covered with TPU. The protective layer prevents oxidation. The cap 6 is sealed by the attraction between the opposite magnetic poles of the second magnetic connecting strip 8 and the first magnetic connecting strip 7. It is also waterproof and dustproof. When the cap 6 is opened, the PDA can be placed in the bag 1. The pen box 4 is made of transparent polycarbonate material, which combines strength and visibility. The pen box 4 can hold pens to prevent them from falling out. The buckle 2 can fasten one end of the pen to further enhance the pen's fixation effect.

[0016] Bag 1 is a silicone bag made of food-grade liquid silicone through injection molding to ensure waterproof performance and a soft touch.

[0017] The elastic arm fixation unit 3 includes a storage slot 34, a roller 31, and a restraint strap 33. Two storage slots 34 are provided, located on the left and right sides of the bag body 1. The roller 31 is rotatably mounted inside the storage slots 34. The end of the restraint strap 33 is fixedly connected to the roller 31. The elastic arm fixation unit 3 also includes a guide roller 32, which is rotatably mounted on the bag body 1 and positioned corresponding to the outlet of the storage slot 34. The guide roller 32 facilitates the smooth entry and exit of the restraint strap 33 from the storage slots 34. The elastic arm fixation unit 3 also includes a connecting block 35 and a torsion spring. 36. Connecting block 35 is fixed on roller 31. One end of torsion spring 36 is fixedly connected to connecting block 35, and the other end of torsion spring 36 is fixedly connected to bag body 1. The end of restraint strap 33 drives roller 31 to rotate. Connecting block 35 on roller 31 drives torsion spring 36 to rotate. The elastic force of torsion spring 36 acts on connecting block 35, so that connecting block 35 drives roller 31 to return to its original position. The restraint strap 33 restrains the patient's arm, thereby fixing bag body 1 on the user's arm. It can automatically adapt to different arm sizes without manual adjustment.

[0018] The restraint strap 33 is made of nylon braided strap with an anti-slip texture on the surface and a skin-friendly silicone pad on the inside, balancing durability and wearing comfort. The roller 31 and guide roller 32 can be made of stainless steel with a nickel-plated surface for rust prevention. The torsion spring 36 is made of 65Mn spring steel and is heat-treated to improve elasticity and fatigue life. The buckle 2 is made of PA66+GF30 nylon fiber-reinforced material to ensure buckling strength. The restraint strap 33 uses a 16-strand nylon braiding process and is coated with an anti-slip silicone coating.

[0019] The working principle of the portable multi-functional PDA bag provided by this utility model is as follows: The bag body 1 is made of food-grade liquid silicone through injection molding to ensure waterproof performance and a soft touch. The pen case 4 is made of transparent polycarbonate material, which combines strength and visibility. The pen case 4 can hold pens to prevent them from falling out. The buckle 2 can fasten one end of the pen to further enhance the pen's fixation effect. The roller 31 and guide roller 32 can be made of stainless steel with a nickel-plated surface for rust prevention. The torsion spring 36 is made of 65Mn spring steel, which is heat-treated to improve elasticity and fatigue life. The buckle 2 is made of PA66+GF30 nylon fiber-reinforced material to ensure fastening strength. The binding strap 33 is made of 16-strand nylon braiding and coated with an anti-slip silicone coating. The second magnetic connecting strip 8 and the first magnetic connecting strip 7 can be made of N52 neodymium iron boron magnets and covered with TPU. The protective layer prevents oxidation. The cap 6 is sealed by the attraction between the opposite magnetic poles of the second magnetic connecting strip 8 and the first magnetic connecting strip 7. It also has waterproof and dustproof effects. The end of the binding strap 33 drives the roller 31 to rotate. The connecting block 35 on the roller 31 drives the torsion spring 36 to rotate. The elastic force of the torsion spring 36 acts on the connecting block 35, so that the connecting block 35 drives the roller 31 to return to its original position. The binding strap 33 binds the patient's arm, thereby fixing the bag 1 on the user's arm. The cap 6 can be opened to place the PDA inside the bag 1.
