Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Embodiment one:

[0026] As shown in the figure, the utility model provides a kind of multi-pipeline dustless drag chain with T-shaped stop, including drag chain body 1, the drag chain body 1 is made of multiple corrugated pipes 2, the corrugated pipe 2 is equipped with continuous corrugated structure 3, and the corrugated structure 3 includes convex segment 4 and concave segment 5, and the corrugated pipe 2 is equipped with stop structure 6, and the stop structure 6 is fixedly connected with the convex segment 4, and the section of stop structure 6 is T-shaped. Figures 1-11 Stop structure 6 is arranged at the intermediate segment position of convex segment 4. Stop structure 6 is arranged at one side or both sides of convex segment 4. Stop structure 6 is fixedly connected with convex segment 4 by vertical bone 7. Stop structure 6 is fixedly connected with convex segment 4 by one-piece forming mode or fusion welding mode or secondary injection molding mode. The corrugated pipe 2 located at both sides of drag chain body 1 is equipped with stop structure 6.

[0027] By the above technical scheme, the drag chain body 1 of the present application is made of multiple corrugated pipes 2, the corrugated pipe 2 is equipped with continuous corrugated structure 3, and the corrugated structure 3 includes convex segment 4 and concave segment 5, and the corrugated pipe 2 is equipped with stop structure 6, and the stop structure 6 is fixedly connected with the convex segment 4, and the section of stop structure 6 is T-shaped, and adjacent stop portions abut each other when the corrugated pipe body 2 is straightened, to form a supporting effect, so that the corrugated pipe body 2 is curled in one direction, and the opposite direction forms a supporting limit, to play a supporting role, to ensure the rigidity of the corrugated pipe body 2 in long-distance suspension, to prevent the corrugated pipe body from landing and rolling over, to improve the smoothness of the corrugated pipe body 2 in the rolling process, and to improve the equipment operation stability.

[0028] Embodiment two:

[0029] As shown in the figure, the utility model provides a kind of multi-pipeline dustless drag chain with T-shaped stop, including drag chain body 1, the drag chain body 1 is made of multiple corrugated pipes 2, the corrugated pipe 2 is equipped with continuous corrugated structure 3, and the corrugated structure 3 includes convex segment 4 and concave segment 5, and the corrugated pipe 2 is equipped with stop structure 6, and the stop structure 6 is fixedly connected with the convex segment 4, and the section of stop structure 6 is T-shaped. Figures 1-11

[0030] ​The cable chain body 1 is composed of multiple parallel corrugated tubes 2, which are made of flexible material and have good bending performance. The surface of the corrugated tube 2 has a continuous corrugated structure 3, which consists of a convex section 4 and a concave section 5. The corrugated structure 3 increases the flexibility of the corrugated tube 2, enabling it to adapt to the movement of the cable chain.

[0031] A stop structure 6 is fixedly connected to the protruding section 4 of the bellows 2. The stop structure 6 has a T-shaped cross-section, including a vertical portion perpendicular to the surface of the bellows 2 and a horizontal portion parallel to the surface of the bellows 2. The T-shaped structure increases the stability and support capacity of the stop structure 6.

[0032] When the bellows 2 is taut, the stop structures 6 on adjacent bellows 2 abut against each other. The T-shaped cross-section of the stop structure 6 allows adjacent stop structures 6 to fit tightly together, forming a stable support point. This abutment restricts the bending of the bellows 2 in one direction, while allowing the bellows 2 to bend freely in another direction.

[0033] The stop structure 6 significantly improves the stability of the cable chain during long-distance suspended operation. When the cable chain is suspended, the bellows 2 tends to sag due to its own weight and the weight of the internal cables. The T-shaped stop structure 6 forms a series of support points, effectively preventing the bellows 2 from collapsing. At the same time, the horizontal part of the T-shaped structure increases the lateral stiffness of the bellows 2, reducing the risk of lateral tipping.

[0034] In practical applications, cable chains can be installed on various industrial equipment to protect and guide flexible components such as cables and oil pipes. They also prevent dust from entering the equipment due to wear and tear on these components during movement. When the equipment moves, the cable chain moves along with it, and the corrugated pipe 2 maintains a stable shape under the action of the T-shaped stop structure 6. Even when used suspended for long distances, the cable chain maintains good operating condition and will not experience serious collapse or tipping.

[0035] The present invention features a simple structure, is easy to manufacture, and is convenient to install and maintain. The T-shaped stop structure 6 can be integrally formed with the corrugated pipe 2, or it can be fixedly connected by welding, bonding, or other methods. The overall structure of the cable chain is compact, occupies little space, and is suitable for various complex industrial environments.

[0036] Example 3:

[0037] like Figures 1-11 As shown, the stop structure 6 of the present invention is located in the middle section of the convex section 4. The cable chain body 1 is composed of multiple corrugated tubes 2. Each corrugated tube 2 has a continuous corrugated structure 3, which includes a convex section 4 and a concave section 5. The stop structure 6 is provided on the corrugated tube 2, and the stop structure 6 is fixedly connected to the convex section 4. The cross-section of the stop structure 6 is T-shaped.

[0038] The drag chain body 1 is composed of a plurality of parallel corrugated pipes 2 made of elastic material. The corrugated pipe 2 is provided with a continuous corrugated structure 3, which is composed of convex segments 4 and concave segments 5 arranged alternately. The corrugated structure 3 makes the corrugated pipe 2 have good bending performance and can adapt to the movement requirements of the drag chain.

[0039] The stop structure 6 is arranged at the middle segment of the convex segment 4, which can provide uniform support force when the corrugated pipe 2 is bent. When the drag chain is in a suspended state, the corrugated pipe 2 tends to sag under the action of its own weight and the weight of the internal cable. However, the T-shaped stop structure 6 located in the middle of the convex segment 4 forms a series of uniformly distributed support points, effectively preventing the sagging of the corrugated pipe 2. At the same time, the horizontal part of the T-shaped structure increases the lateral stiffness of the corrugated pipe 2, reducing the risk of lateral collapse.

[0040] During the movement of the drag chain, the corrugated pipe 2 will be bent. Since the stop structure 6 is arranged in the middle of the convex segment 4, the stop structure 6 can maintain a relatively stable position when the corrugated pipe 2 is bent. This arrangement makes the drag chain transition smoothly during bending and straightening, reducing resistance and wear during movement.

[0041] Arranging the stop structure 6 in the middle of the convex segment 4 is also beneficial to the overall appearance of the drag chain, making the drag chain more symmetrical and harmonious in appearance.

[0042] Embodiment Four:

[0043] As shown in Figures 1-11 The stop structure 6 of the present application is arranged on one side or both sides of the convex segment 4. The drag chain body 1 is composed of a plurality of corrugated pipes 2. Each corrugated pipe 2 is provided with a continuous corrugated structure 3, which includes convex segments 4 and concave segments 5. The corrugated pipe 2 is provided with a stop structure 6, which is fixedly connected with the convex segment 4, and the cross section of the stop structure 6 is T-shaped.

[0044] The drag chain body 1 is composed of a plurality of parallel corrugated pipes 2 made of elastic and ductile material. The corrugated pipe 2 is provided with a continuous corrugated structure 3, which is composed of convex segments 4 and concave segments 5 arranged alternately. The corrugated structure 3 gives the corrugated pipe 2 good bending performance, enabling it to adapt to various movement states of the drag chain.

[0045] A stop structure 6 is arranged on one side or both sides of each convex segment 4. The stop structure 6 is made of relatively hard material to provide sufficient support strength and stiffness. The cross section of the stop structure 6 is T-shaped, including a vertical part perpendicular to the surface of the corrugated pipe 2 and a horizontal part parallel to the surface of the corrugated pipe 2. The T-shaped structure increases the stability and support area of the stop structure 6.

[0046] By placing the stop structure 6 on one or both sides of the convex section 4, targeted support can be provided when the bellows 2 bends. When the stop structure 6 is placed on one side of the convex section 4, it can provide support for bending in a specific direction, which can be applied to lightweight multi-pipe cable chains. It can be placed on the bellows 2 on both sides of the cable chain to save production costs. When it is placed on both sides of the convex section 4, it can provide support in two directions simultaneously. It can also be applied to lightweight multi-pipe cable chains. It can be placed on the bellows 2 according to support requirements to improve the support performance of the multi-pipe cable chain.

[0047] When the bellows 2 is taut, the stop structures 6 on adjacent bellows 2 abut against each other. Since the stop structures 6 are located on one or both sides of the convex section 4, the abutment points form one or two stable support lines. This design allows the cable chain to remain rigid in some directions and flexible in others, thus adapting to different motion requirements.

[0048] When the cable chain is suspended, the bellows 2 tends to sag due to its own weight and the weight of the internal cables. However, the T-shaped stop structures 6 located on one or both sides of the convex section 4 form a series of support points, effectively preventing the bellows 2 from collapsing. The horizontal portion of the T-shaped structure increases the lateral stiffness of the bellows 2, reducing the risk of lateral tipping.

[0049] Example 5:

[0050] like Figures 1-11 As shown, the stop structure 6 of the present invention is fixedly connected to the convex section 4 via the upright rib 7. The cable chain body 1 is composed of multiple corrugated tubes 2, each corrugated tube 2 having a continuous corrugated structure 3, including a convex section 4 and a concave section 5. A stop structure 6 is provided on the convex section 4 of the corrugated tube 2, and the cross-section of the stop structure 6 is T-shaped.

[0051] The support rib 7 is a longitudinal support structure perpendicular to the surface of the bellows 2. During manufacturing, one end of the support rib 7 is connected to the bottom of the stop structure 6, and the other end is tightly connected to the protrusion 4 of the bellows 2. The structure of the support rib 7 ensures that the height of the stop structure 6 is approximately equal to the height of the bellows 2, so that the bellows 2 can remain taut when the stop structures 6 are in contact with each other.

[0052] Example 6:

[0053] like Figures 1-11 As shown, the stop structure 6 of the present invention is fixedly connected to the convex section 4 by integral molding, welding, or secondary injection molding. The cable chain body 1 is composed of multiple corrugated tubes 2, each corrugated tube 2 having a continuous corrugated structure 3, including a convex section 4 and a concave section 5. A stop structure 6 is provided on the convex section 4 of the corrugated tube 2, and the cross-section of the stop structure 6 is T-shaped. To ensure a firm connection between the stop structure 6 and the corrugated tube 2, this embodiment employs welding or secondary injection molding methods.

[0054] Welding is a commonly used material joining technique suitable for thermoplastic materials. In this embodiment, when welding is selected, the T-shaped stop structure 6 is first placed at a predetermined position on the protrusion 4 of the bellows 2. Then, the contact surface is heated using a hot melt device or an ultrasonic device to melt the materials of the two components at the contact surface. Under pressure, the molten materials interpenetrate and form a strong molecular bond. After cooling, the T-shaped stop structure 6 and the protrusion 4 of the bellows 2 form a single unit with high connection strength and are not easily separated.

[0055] One-piece injection molding is another method for manufacturing the connection between the T-shaped stop and the corrugated pipe 2 protrusion 4. This method directly molds the T-shaped stop structure 6 as a single piece during the production of the corrugated pipe 2. Specifically, a mold incorporating the corrugated pipe 2 and the T-shaped stop structure 6 is designed first. During injection molding, molten plastic material is injected into the mold, filling the entire cavity, including the corrugated pipe 2 and the T-shaped stop structure 6. After cooling, a one-piece corrugated pipe 2 with a T-shaped stop is obtained.

[0056] The secondary injection molding method involves directly molding the stop structure 6 onto the protruding section 4 after the corrugated pipe body 2 has been formed. This process includes the following steps: First, the already formed corrugated pipe body 2 is placed into a specially designed mold. The shape of the mold cavity corresponds to the required stop structure 6. Then, molten plastic material is injected into the mold cavity. After injection molding, it cools and solidifies, forming the stop structure 6 integral with the corrugated pipe body 2. The advantages of the secondary injection molding method are that it achieves complete integration of the stop structure 6 and the corrugated pipe body 2, resulting in high connection strength and good appearance consistency.

[0057] In practical applications, welding is suitable for post-processing or customized needs. For example, when it is necessary to add a T-shaped stop structure 6 to an existing bellows 2, welding technology can be used. The advantage of this method is its high flexibility; the position and number of T-shaped stops can be adjusted according to specific requirements. However, the welding process requires precise control of temperature and pressure to ensure the quality of the connection.

[0058] One-piece injection molding is more suitable for mass production. This method ensures the consistency of position and size of each T-shaped stop structure 6, improving the standardization of the product. At the same time, one-piece molded products have better overall integrity, with no connecting interfaces, thus performing better under dynamic loads. However, one-piece injection molding requires specialized mold design and manufacturing, resulting in a larger initial investment.

[0059] Example 7:

[0060] like Figures 1-11As shown, the corrugated pipes 2 located on both sides of the cable chain body 1 are equipped with stop structures 6. The cable chain body 1 is composed of multiple corrugated pipes 2, each corrugated pipe 2 having a continuous corrugated structure 3, including a convex section 4 and a concave section 5. A stop structure 6 is provided on the convex section 4 of the corrugated pipe 2, and the cross-section of the stop structure 6 is T-shaped.

[0061] The corrugated tubes 2 on both sides of the cable chain body 1 refer to the two outermost corrugated tubes 2 located in the width direction of the cable chain. T-shaped stop structures 6 are set on these two corrugated tubes 2, forming a symmetrical support system. This arrangement makes full use of the structural characteristics of the cable chain, maximizing its rigidity and stability while ensuring the overall flexibility of the cable chain.

[0062] Specifically, when the cable chain body 1 is taut, the T-shaped stop structures 6 on both sides of the corrugated pipes 2 correspond to each other, forming a pair of parallel support lines. These two support lines extend along the length of the cable chain, providing strong lateral support for the entire cable chain system. This design effectively prevents lateral deformation or twisting that may occur when the cable chain is used suspended for long distances.

[0063] During the dynamic use of the cable chain, the T-shaped stops 6 on both sides serve as guides and limiters. When the cable chain bends, the inner T-shaped stops 6 move closer together, while the outer T-shaped stops 6 slightly separate. This movement pattern ensures that the cable chain maintains its shape during bending, avoiding excessive deformation or twisting.
