[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] like Figures 1-4 As shown, this utility model provides a corrugated pipe with a stop, including a corrugated pipe body 1. The corrugated pipe body 1 has a continuous corrugated structure 2, which includes a convex section 3 and a concave section 4. A stop structure 5 is provided at the middle section of the convex section 3. The stop structure 5 has a T-shaped cross-section, and a stop structure 5 is provided every other convex section 3. The stop structure 5 has an L-shaped cross-section. Each convex section 3 is provided with a stop structure 5. A stop structure 5 is provided every other convex section 3. The stop structure 5 is fixedly connected to the convex section 3 by integral molding, welding, or secondary injection molding.

[0021] Through the above technical solution, the corrugated pipe body 1 of the present invention is provided with a continuous corrugated structure 2. The corrugated structure 2 includes a convex section 3 and a concave section 4. A stop structure 5 is provided in the middle section of the convex section 3. When the corrugated pipe body 1 is straightened, the adjacent stop structures 5 abut against each other to form a supporting effect, so that the corrugated pipe body 1 curls in one direction and forms a supporting restriction in the opposite direction, thus playing a supporting role, ensuring the rigidity of the corrugated pipe body 1 when suspended over a long distance, preventing the corrugated pipe body from collapsing or tipping over, improving the smoothness of the corrugated pipe body 1 during the rolling process, and improving the stability of equipment operation.

[0022] The stop structure 5 of the present invention has a T-shaped cross section, and a stop structure 5 is provided at every interval of a protrusion 3. When the corrugated pipe body 1 is straightened, the adjacent stop structures 5 abut against each other to form a supporting effect, so that the corrugated pipe body 1 is curled in one direction. When it is bent in the opposite direction, the stop structure 5 abuts against the adjacent protrusion 3 to provide support. This design reduces the number of stop structures 5, reduces production costs, and at the same time ensures the rigidity of the corrugated pipe body 1 when suspended over a long distance.

[0023] Example 2:

[0024] like Figures 1-4 As shown, the corrugated pipe body 1 of the present invention has a continuous corrugated structure 2, which is composed of alternating convex sections 3 and concave sections 4. The corrugated pipe body 1 is made of flexible material, giving it good bending and compressive strength. The design of the convex sections 3 and concave sections 4 allows the corrugated pipe body 1 to maintain a certain rigidity while possessing high flexibility, adapting to various complex installation environments. A stop structure 5 is provided in the middle of the convex section 3 of the corrugated pipe body 1. The stop structure 5 is a key component of the corrugated pipe, used to enhance the structural stability of the corrugated pipe. The stop structure 5 is integrally formed with the convex section 3, or fixed to the convex section 3 through post-processing. The presence of the stop structure 5 does not affect the basic corrugated structure 2 of the corrugated pipe body 1, but significantly improves the support capacity of the corrugated pipe under certain usage conditions. When the corrugated pipe is under tension, the stop structures 5 on adjacent convex sections 3 contact each other, forming a support point. This support effectively prevents the corrugated pipe from collapsing in the middle when used suspended for long distances. Meanwhile, the stop structure 5 enhances the lateral stability of the bellows, reducing the possibility of it tipping over during use. The height, width, and shape of the stop structure 5 are optimized to provide sufficient support without excessively affecting the flexibility of the bellows. The material of the stop structure 5 is the same as or compatible with the bellows body 1, ensuring the consistency and durability of the overall structure.

[0025] Example 3:

[0026] like Figures 1-4As shown, the bellows body 1 of the present invention has a continuous corrugated structure 2. The corrugated structure 2 is composed of alternating convex sections 3 and concave sections 4, forming the basic shape of the bellows. In this embodiment, a stop structure 5 is located in the middle of the convex section 3. The cross-section of the stop structure 5 is T-shaped, which increases the support area and strength of the stop structure 5. This allows the stop structure 5 to provide more effective support when the bellows is under pressure. The stop structures 5 are arranged in an intermittent manner, that is, one stop structure 5 is set every other convex section 3. This arrangement balances the support effect and production cost. By setting a stop structure 5 on one of every two convex sections 3, when the bellows is under tension, the T-shaped stop structures 5 on adjacent convex sections 3 will contact each other. The transverse portion of the T-shaped structure forms a stable support surface, preventing the bellows from collapsing in the middle when suspended for a long distance.

[0027] Example 4:

[0028] like Figures 1-4 As shown, the bellows body 1 of the present invention has a continuous corrugated structure 2. The corrugated structure 2 consists of alternating convex sections 3 and concave sections 4. A stop structure 5 is provided at the middle position of the convex section 3, and the stop structure 5 has an L-shaped cross-section. The L-shaped stop structure 5 includes a vertical portion perpendicular to the surface of the convex section 3 and a horizontal portion parallel to the surface of the convex section 3. The vertical portion extends outward from the surface of the convex section 3, and the horizontal portion extends from the top of the vertical portion toward one side of the convex section 3. When the bellows is in a straight state, the L-shaped stop structures 5 on adjacent convex sections 3 contact each other to form a support. Specifically, the horizontal portion of the L-shaped stop structure 5 on one convex section 3 contacts the vertical portion of the L-shaped stop structure 5 on the adjacent convex section 3. This contact method provides stable support and enhances the rigidity of the bellows in a long-distance suspended state. When the bellows bends toward the opening of the L-shaped structure, the L-shaped stop structure 5 allows the bellows to bend freely. When the bellows bends towards the direction of the L-shaped structure's closure, the L-shaped stop structure 5 contacts the adjacent protruding section 3, providing resistance and support. The design of the L-shaped stop structure 5 not only increases the rigidity of the bellows but also maintains its flexibility in a certain direction. This structure allows the bellows to maintain a certain level of rigidity while still possessing good bending capacity, adapting to complex operating environments. The horizontal portion of the L-shaped stop structure 5 also prevents excessive bending of the bellows, providing protection. During the bellows' movement, the L-shaped stop structure 5 effectively reduces sagging and tipping, improving the smoothness of the bellows' movement and the stability of equipment operation.

[0029] Example 5:

[0030] like Figures 1-4As shown, each convex segment 3 of the bellows of the present invention is provided with a stop structure 5. The bellows body 1 has a continuous corrugated structure 2, which is composed of alternating convex segments 3 and concave segments 4. A stop structure 5 is provided at the middle position of each convex segment 3, and the cross-section of the stop structure 5 is L-shaped. The L-shaped stop structure 5 is composed of a vertical portion perpendicular to the surface of the convex segment 3 and a horizontal portion parallel to the surface of the convex segment 3. The vertical portion extends outward from the surface of the convex segment 3, and the horizontal portion extends from the top of the vertical portion toward one side of the convex segment 3. When the bellows is straightened, the L-shaped stop structure 5 on each convex segment 3 contacts the L-shaped stop structure 5 on the adjacent convex segment 3. Specifically, the horizontal portion of the L-shaped stop structure 5 on one convex segment 3 contacts the vertical portion of the L-shaped stop structure 5 on the adjacent convex segment 3. This dense distribution of stop structures 5 provides maximum support and significantly enhances the rigidity of the bellows in a long-distance suspended state. When the bellows bends towards the opening of the L-shaped structure, all L-shaped stop structures 5 allow the bellows to bend freely. When the bellows bends towards the closing direction of the L-shaped structure, each L-shaped stop structure 5 contacts the adjacent protrusion 3, providing continuous resistance and support. This design allows the bellows to maintain high rigidity while still possessing a certain degree of bending capability.

[0031] Example 6:

[0032] like Figures 1-4 As shown, the bellows of the present invention has a stop structure 5 provided at every interval of a protruding section 3. The body has a continuous corrugated structure 2, which is composed of alternating protruding sections 3 and concave sections 4. A stop structure 5 is provided at the middle position of every other protruding section 3, and the stop structure 5 has an L-shaped cross-section. The L-shaped stop structure 5 includes a vertical portion perpendicular to the surface of the protruding section 3 and a horizontal portion parallel to the surface of the protruding section 3. The vertical portion extends outward from the surface of the protruding section 3, and the horizontal portion extends from the top of the vertical portion toward one side of the protruding section 3. When the bellows is straightened, the protruding section 3 with the stop structure 5 will contact the adjacent protruding section 3 without the stop structure 5. Specifically, on a protruding section 3 with an L-shaped stop structure 5, the horizontal portion of the L-shaped stop structure 5 will contact the surface of the adjacent protruding section 3 without the stop structure 5. This design of the spaced stop structures 5 provides sufficient support while reducing manufacturing complexity and cost. When the bellows bends towards the opening of the L-shaped structure, the L-shaped stop structure 5 allows the bellows to bend freely. When the bellows bends towards the closing direction of the L-shaped structure, the L-shaped stop structure 5 contacts the adjacent convex section 3 without a stop structure 5, providing resistance and support. This design maintains a certain rigidity of the bellows while also preserving good flexibility. Compared to a design where each convex section 3 has a stop structure 5, this spaced arrangement reduces the number of stop structures 5, lowering the weight and manufacturing cost of the bellows.

[0033] Example 7:

[0034] As Figures 1-4 shown, the corrugated pipe body 1 of the present application is provided with a continuous corrugated structure 2. The corrugated structure 2 is composed of alternating convex segments 3 and concave segments 4, forming the basic structure of the corrugated pipe. In this embodiment, the stop structure 5 is fixedly connected with the convex segment 3 in three ways: one-piece forming, fusion, and secondary injection molding. These three connection methods are designed to ensure a firm bond between the stop structure 5 and the corrugated pipe body 1, improving the strength and durability of the overall structure. The fusion method involves hot fusion connection between the pre-made stop structure 5 and the convex segment 3 of the corrugated pipe body 1. The process includes the following steps: First, fix the corrugated pipe body 1 on a special fixture, ensuring that the convex segment 3 is in the correct position. Then, place the pre-made stop structure 5 at the predetermined position of the convex segment 3. Next, use a hot fusion device to heat the contact surface of the stop structure 5 and the convex segment 3, causing the materials of the two to fuse at high temperature, or use an ultrasonic welding device. Finally, cool and solidify to form a firm connection. The advantage of the fusion method is that the operation is relatively simple, suitable for small batch production or modification of existing corrugated pipes. At the same time, this method allows the use of different materials for the stop structure 5, increasing the flexibility of design. However, the fusion point may become a weak link in the structure, and strict control of fusion parameters is needed to ensure the quality of the connection. The one-piece forming method uses a specially designed mold that includes the stop structure 5. The molten material is injected into the mold, allowing the stop structure 5 and the convex segment 3 to be formed in one piece. The secondary injection molding method forms the stop structure 5 directly on the convex segment 3 after the corrugated pipe body 1 has been formed. The process includes the following steps: First, place the already formed corrugated pipe body 1 into a specially designed mold. The shape of the mold cavity corresponds to the desired stop structure 5. Then, inject molten plastic material into the mold cavity. After injection, cool and solidify to form the stop structure 5 integrated with the corrugated pipe body 1. The advantage of the secondary injection molding method is that it can achieve complete integration of the stop structure 5 with the corrugated pipe body 1, with high connection strength and good appearance consistency.
