[0028] Embodiment two:

[0029] As Figures 1-9As shown, the utility model of first clamping frame 1 and second clamping frame 2 are fixedly connected through connecting piece 3. One end of first clamping frame 1 is provided with hook head 4, and second clamping frame 2 is provided with clamping portion 5 matched with hook head 4. First clamping frame 1 is semicircular arc or semielipse or rectangle, and the arc inner side is smooth, facilitating the accommodation of cable. One end of first clamping frame 1 is provided with upwardly curved hook head 4, and the top end of hook head 4 is slightly inwardly curved, forming an inverted hook structure. Second clamping frame 2 is semicircular arc or semielipse or rectangle. One end of second clamping frame 2 is provided with clamping portion 5 formed by an outwardly protruding structure. The protrusion is slightly smaller than the width of hook head 4, and this design ensures that hook head 4 is not easily detached after insertion. The two ends of connecting piece 3 are fixedly connected with first clamping frame 1 and second clamping frame 2 respectively. Connecting piece 3 has elastic deformation performance, allowing the two clamping frames to open and close relative to each other. In use, first clamping frame 1 is first inserted into the recess inside the corrugated pipe. Then second clamping frame 2 is opened, and the cable is placed in first clamping frame 1. Finally, second clamping frame 2 is closed with first clamping frame 1, so that hook head 4 is inserted into clamping portion 5, completing the fixation. When the cable needs to be replaced or adjusted, second clamping frame 2 is pulled outward, so that hook head 4 is detached from clamping portion 5, and the fixing frame can be opened. This design greatly simplifies the installation and replacement process of the cable, improving work efficiency. The overall structure of the fixing frame is simple and compact, easy to manufacture and install. The arc design of first clamping frame 1 and second clamping frame 2 matches the internal structure of the corrugated pipe, ensuring stability after installation. The design of hook head 4 and clamping portion 5 provides reliable fixation effect, preventing the cable from loosening or falling off during the movement of the drag chain. The design of connecting piece 3 allows the two clamping frames to freely open and close within a certain range, facilitating the installation and adjustment of the cable by the operator. The utility model not only simplifies the installation process, but also improves the stability of the cable in the drag chain. It is suitable for various types of drag chain systems, and can effectively solve the problems of difficult cable installation and easy loosening in traditional drag chains.

[0030] Example three:

[0031] As Figures 5-8 shown, the utility model increases the separation arm 6 structure on the first clamping frame 1 or the second clamping frame 2 on the basis of example one.

[0032] In the first implementation, the first bracket 1 is provided with a partition arm 6. The first bracket 1 can be provided with multiple partition arms 6 at equal intervals. Each partition arm 6 is a columnar structure with a height slightly lower than the arc height of the bracket and a length comparable to the width of the bracket. The number and interval of the partition arms 6 can be adjusted according to actual needs. For example, for common three-phase cables, two partition arms 6 can be provided to divide the internal space of the fixing frame into three regions. For cases where multiple cables of different types need to be fixed at the same time, the number of partition arms 6 can be increased. When installing the cables, the first bracket 1 is first inserted into the corrugated pipe. Then, different cables are placed in the respective regions separated by the partition arms 6. Finally, the second bracket 2 is closed, and the fixing is completed.

[0033] In the second implementation, the second bracket 2 is provided with a partition arm 6. The second bracket 2 can be provided with multiple partition arms 6 at equal intervals. Each partition arm 6 is a columnar structure with a height slightly lower than the arc height of the bracket and a length comparable to the width of the bracket. The number and interval of the partition arms 6 can be adjusted according to actual needs. For example, for common three-phase cables, two partition arms 6 can be provided to divide the internal space of the fixing frame into three regions. For cases where multiple cables of different types need to be fixed at the same time, the number of partition arms 6 can be increased. When installing the cables, the second bracket 2 is first inserted into the corrugated pipe. Then, different cables are placed in the respective regions separated by the partition arms 6. Finally, the first bracket 1 is closed, and the fixing is completed.

[0034] The provision of the partition arm 6 effectively solves the problem of multiple cables intertwining in the same corrugated pipe. During the movement of the drag chain, even if subjected to vibration and shaking, different cables will be confined to their respective regions and will not interfere with each other. This design of the fixing frame with a partition arm 6 not only retains all the advantages of the basic fixing frame but also further improves the stability and management convenience of the cables in the drag chain. It is particularly suitable for complex drag chain systems that need to fix multiple cables of different types at the same time.

[0035] Example Four:

[0036] As Figures 1-9As shown in the utility model, structural recesses 9 are arranged in the middle part of the connecting piece 3. The connecting piece 3 is in a strip structure, and the two ends are fixedly connected with the first clamping frame 1 and the second clamping frame 2 respectively. The middle part of the connecting piece 3 is provided with a transverse structural recess 9, the recess is in a shallow "U" shape, and the depth is about one third of the thickness of the connecting piece 3. The two ends of the structural recess 9 adopt a circular arc transition to avoid stress concentration. The main function of the structural recess 9 is to improve the elastic performance of the connecting piece 3. When the operator opens or closes the fixing frame, the connecting piece 3 needs to produce certain bending deformation. The existence of the structural recess 9 reduces the rigidity of this area, so that the deformation is easier. When the fixing frame is opened, tensile stress will be generated at the structural recess 9, and the materials on both sides of the recess are stretched. The existence of the recess makes the stress distribution more uniform, avoids stress concentration, and thus improves the fatigue life of the connecting piece 3. When the fixing frame is closed, compressive stress will be generated at the structural recess 9, and the materials on both sides of the recess are compressed. The recess provides a space for material deformation, so that the closing process is smoother, and the force required for operation is reduced.

[0037] Example five:

[0038] As Figures 3-4 shown, the first clamping frame 1 and the second clamping frame 2 of the utility model are both provided with a fixing part 7. The fixing part 7 is a keel structure for clamping the built-in corrugated pipe on the clamping frame, and the fixing part 7 is formed by extending inward from the first clamping frame 1 or the second clamping frame 2 body. The fixing part 7 is provided with a clamping arm 8, and the clamping arm 8 is arranged by extending from both sides of the fixing part 7. The clamping arm 8 can cover the built-in keel from top to bottom and from both sides. The built-in keel is a support structure inside the corrugated pipe for enhancing the strength, and extends along the length direction of the corrugated pipe. The existence of the keel improves the overall rigidity and carrying capacity of the drag chain, and prevents the corrugated pipe from deforming or collapsing during movement. The fixing part 7 clamps the keel through the clamping arm 8, so that the fixing frame and the corrugated pipe form a stable connection. When installing, the operator inserts the first clamping frame 1 into the corrugated pipe, puts the keel into the first clamping frame 1, and then fixes the second clamping frame 2 with the first clamping frame 1 through clamping, so that the keel is fixed.

[0039] Example six:

[0040] As Figures 1-9As shown, the first bracket 1 and the second bracket 2 are both provided with a fixing groove 10. The fixing groove 10 is a groove structure, located on the outer surface of the bracket. The shape and size of the fixing groove 10 match the protruding structure on the inner wall of the corrugated pipe, used to enhance the stability of the fixing frame in the corrugated pipe. The corresponding protruding structure is provided on the inner wall of the corrugated pipe, and the groove structure is clamped and fixed with the protruding structure, so that the first bracket 1 and the second bracket 2 are respectively fixed on the corrugated pipe. In order to improve the fixing effect, the inner wall of the fixing groove 10 is designed with a small friction enhancing structure. These structures can be small protrusions or textures, which can increase the contact area and friction between the fixing groove 10 and the protrusions of the corrugated pipe. This design ensures easy installation while improving the stability of the fixing frame during use.

[0041] Example seven:

[0042] As Figures 1-9 shown, the first bracket 1, the second bracket 2 and the connecting piece 3 are manufactured by integral molding process. This integrated design eliminates the connection points of the traditional multi-component assembled fixing frame, improves the overall structural strength and stability, and reduces the production cost. The manufacturing process of integral molding adopts injection molding technology. The molten engineering plastic is injected into the precision mold, and the required fixing frame shape is formed after cooling. The injection molding process can accurately control the size and shape of the product, ensuring the consistency and compatibility of each part of the fixing frame. The connecting piece 3 between the first bracket 1 and the second bracket 2 forms a flexible hinge structure in the integral molding process. This hinge allows the two brackets to open and close, while maintaining the integrity of the overall structure. The design of the flexible hinge takes into account the repeated opening and closing during use, and the material selection and structure optimization ensure the reliability of long-term use.
