[0018] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0019] In the specific implementation process, Figures 1 to 3 As shown, the waterproof outdoor shoes with a PU upper 3 hot-pressed with a TPU strip include a waterproof shoe body 1, a reinforcement belt 6 is arranged at the oblique top of the waterproof shoe body 1 along its bending angle, two waterproof baffles 7 are arranged at both ends of the front side of the waterproof shoe body 1, and the two waterproof baffles 7 are bent along the outer side wall of the waterproof shoe body 1 and cover the front side thereof, and a waterproof block 8 is arranged at the bottom of the reinforcement belt 6 on the waterproof shoe body 1, and the bottom cross section of the waterproof block 8 is arranged in an arc shape;
[0020] By configuring the reinforcement belt 6 precisely arranged along the bending angle at the oblique top of the waterproof shoe body 1, not only the stability of the upper 3 structure is strengthened, but also the pressure of the foot on the upper 3 during walking is effectively dispersed, thereby extending the service life of the shoe;
[0021] The two waterproof baffles 7 are bent at a certain angle along the outer side wall of the waterproof shoe body 1 and tightly cover the front side of the upper 3, forming an effective protective barrier to effectively prevent moisture from penetrating from the toe part, ensuring that the feet stay dry in rainy days or wading environments;
[0022] The waterproof block 8 arranged at the bottom of the reinforcing belt 6 has an arc-shaped bottom cross-section, which is intended to adapt to the curve of the foot, enhance the fit and comfort, and further enhance the waterproof performance to prevent moisture from penetrating through the seam between the sole 2 and the upper 3. When walking on a wet or flooded ground, water may temporarily accumulate in the sole 2. Thanks to the arc-shaped structure of the waterproof block 8, it can effectively prevent moisture from being pulled back to the upper 3 by the pressure difference inside the shoe body, further ensuring a dry environment inside the shoe, ensuring that users can enjoy a comfortable wearing experience under various complex climatic conditions.
[0023] The waterproof shoe body 1 includes a sole 2 and an upper 3. The top of the sole 2 is fixedly connected to the bottom of the upper 3, the oblique top of the upper 3 is fixedly connected to the reinforcement belt 6, the front side of the upper 3 is fixedly connected to the waterproof block 8, the two ends of the front side of the upper 3 are respectively fixedly connected to two waterproof baffles 7, the tops of both sides of the upper 3 are respectively provided with breathable waterproof areas 5, and the rear side of the upper 3 is provided with a handle 4.
[0024] The material of the reinforcing belt 6, the waterproof baffle 7 and the waterproof block 8 is TPU, which has excellent elasticity and durability.
[0025] The working principle provided by the utility model is as follows: when the utility model is implemented, the sole 2 and the upper 3 are first tightly combined together through precise and firm stitching technology to ensure that the connection between the two is tight and seamless. The reinforcing belt 6, the waterproof baffle 7 and the waterproof block 8 are accurately cut according to the preset size and shape to ensure that they can perfectly fit the specific area of the shoe. It uses high-quality TPU material, has excellent elasticity and durability, and can provide strong waterproof protection while ensuring comfort. Subsequently, the cut reinforcement belt 6, waterproof baffle 7 and waterproof block 8 are placed one by one in a special mold to ensure that the waterproof component is completely fitted with the surface of the upper 3 during the hot pressing process without leaving any gaps or holes. Under high temperature and high pressure, the waterproof component of TPU material is firmly welded and covered on the corresponding position of the upper 3, forming a solid protective barrier to avoid deformation and damage caused by long-term use; the waterproof baffle 7 focuses on preventing moisture from penetrating from vulnerable parts such as the toe; and the waterproof block 8 with an arc-shaped design at the bottom not only enhances the fit and comfort between the foot and the sole 2, but also effectively prevents moisture from penetrating through the seam between the sole 2 and the upper 3, and prevents the accumulated water in the sole 2 from flowing back into the upper 3, thereby comprehensively improving the waterproof performance of the entire pair of shoes, so that it can maintain a good waterproof effect under various adverse weather conditions.
