Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example 1:

according to attached drawing 1~ figure 4, the utility model relates to a waterproof ventilated membrane pore structure of step with prevent stabbing protect function, waterproof ventilated membrane pore counter bore on for locating the casing 1 of product, adopt sectional type reducing through-hole design, set up waterproof ventilated membrane pore portion department whole and be syllogic structure in this embodiment, divide into to outer counter bore section, middle section and with the inside section of waterproof ventilated membrane 2 contact, wherein the aperture in middle section is minimum. In order to ensure the attractive appearance of the product, the joint section is arranged at the joint of the counter sink hole section and the middle section of the waterproof breathable membrane hole, and the appearance of the counter sink hole section can be in various forms such as diamond, rectangle, circle, polygon and groove.

The inner section is provided with a step 3 matched with the size and the shape of the waterproof breathable film hole, one part of the step 3 is connected with the inner wall of the waterproof breathable film hole into a whole, the other part of the step 3 is spaced from the inner wall of the waterproof breathable film hole, a gap channel 5 for internal and external air circulation is formed along the inner wall of the waterproof breathable film hole, the joint of the outward surface of the step 3 and the middle section and the inner section of the waterproof breathable film hole is positioned at the same horizontal plane, the size and the shape of the gap channel 5 can be determined according to the actual requirements of products, such as a waist-shaped channel, a circular channel, a rectangular channel and the like, preferably an arc-shaped channel of 0.2-0.3 mm, most sharp objects can be prevented from being penetrated, even if the sharp objects 6 penetrate the waterproof breathable film hole at the maximum angle, the step 3 is matched with the inner wall of the waterproof breathable film hole, the breathable film is protected from being pierced and damaged, and the situation that the waterproof breathable film is damaged due to the fact that common sharp objects are penetrated by accident can be effectively avoided, and the shapes of the waterproof breathable film holes and the steps are consistent, so that the manufacturing process can be simplified.

The inside section opening part in the inboard waterproof ventilative membrane hole of product casing still is equipped with waterproof ventilated membrane recess 4, and its degree of depth cooperatees with waterproof ventilated membrane thickness, waterproof ventilated membrane recess 4 surface is equipped with the fillet recess, walks gluey smooth and easy nature when can promoting moulding plastics, reduces the internal stress of plastic material.
