Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1:

[0036] As Figures 1 - 10As shown in the figure, a drag chain provided by the present invention includes a drag chain body 1, and the drag chain body 1 includes a first joint 2 and a second joint 3. Both the first joint 2 and the second joint 3 are provided with half pipes 4. The half pipes 4 of the first joint 2 and the half pipes 4 of the second joint 3 are covered to form a corrugated pipe 5. Both the first joint 2 and the second joint 3 are provided with multiple half pipes 4. The first joint 2 and the second joint 3 are fixedly connected through a buckle structure 6. The buckle structure 6 includes a first fastener 7 and a second fastener 8. The first fastener 7 is arranged on the first joint 2, and the second fastener 8 is arranged on the second joint 3. The second joint 3 is provided with the same number of half pipes 4 as the first joint 2. One end of the first joint 2 is fixedly connected to one end of the second joint 3 through a soft belt 9. The first joint 2 and the second joint 3 are fixedly connected through at least one buckle structure 6, and the ends of the first joint 2 and the second joint 3 are fixedly connected through a buckle structure 6. The first joint 2 is provided with at least one half pipe 4. The second joint 3 is fixedly covered with at least one first joint 2, and the number of half pipes 4 of the second joint 3 is equal to the sum of the number of half pipes 4 of all the first joints 2 thereon. Both sides of the first joint 2 are provided with first fasteners 7. The second joint 3 is provided with second fasteners 8 that match the positions and numbers of the first fasteners 7. The first joint 2 and the second joint 3 are fixedly connected through at least two buckle structures 6, and both sides of the first joint 2 and the second joint 3 are fixedly connected through a buckle structure 6. The half pipes 4 of the first joint 2 are all provided with a stop structure A 10. The half pipes 4 of the second joint 3 are all provided with a stop structure B 11. The half pipes 4 located on both sides of the first joint 2 are provided with a stop structure C 12.

[0037] A connecting buckle of a drag chain includes a first clamping plate 13 and a second clamping plate 14. The first clamping plate 13 is fixedly connected to the second clamping plate 14 through a connecting block 15. Both the first clamping plate 13 and the second clamping plate 14 are provided with barbs 16. Both sides of the first clamping plate 13 and the second clamping plate 14 are provided with bumps 17.

[0038] A zipper structure of a drag chain includes a first connecting plate 18 and a second connecting plate 19. Both the first connecting plate 18 and the second connecting plate 19 are continuously and intermittently provided with a plurality of locking heads 20. The locking heads 20 of the first connecting plate 18 and the locking heads 20 of the second connecting plate 19 are arranged in a staggered manner. A bayonet 21 is arranged at the interval between the locking heads 20.

[0039] Through the above technical solutions, the drag chain body 1 of the present invention includes a first joint 2 and a second joint 3. Both the first joint 2 and the second joint 3 are provided with multiple half pipes 4. The half pipes 4 of the first joint 2 and the half pipes 4 of the second joint 3 are covered to form a corrugated pipe 5. The first joint 2 and the second joint 3 are fixedly connected through a buckle structure 6, ensuring the stability of the structure of the drag chain body 1. During use, according to the thickness, weight, and type of the cables, they are reasonably routed in different corrugated pipes 5, reducing the number of cables in a single corrugated pipe 5, reducing the wear between the cables, preventing signal interference between the cables, optimizing the distribution of the cables, improving the stability of the center of gravity of the drag chain body 1, and ensuring the normal operation of the equipment.

[0040] Embodiment 2:

[0041] As Figures 1 - 10 shown, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. A plurality of half-tube 4 structures are provided on both the first assembly 2 and the second assembly 3, and these half-tubes 4 are arranged in parallel along the transverse direction of the drag chain body 1. When the first assembly 2 and the second assembly 3 are covered with each other, the corresponding half-tubes 4 will combine to form a complete corrugated pipe 5 channel. Each corrugated pipe 5 channel has an independent internal space, which can be used to accommodate different types of cables or pipelines.

[0042] In a specific implementation, the first assembly 2 and the second assembly 3 are reliably connected through a snap structure 6. The snap structure 6 is composed of a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3. The first fastener 7 and the second fastener 8 are designed with complementary geometric shapes, and when the two are snapped together, a mechanical interlocking effect will be generated. This snapping method not only ensures the firmness of the connection but also facilitates disassembly operations when needed.

[0043] The working principle of this embodiment is to achieve classified management of cables through multiple independent corrugated pipe 5 channels. Different types of cables can be arranged in different corrugated pipes 5 respectively, effectively avoiding mutual interference and abrasion between the cables. At the same time, the multi-channel design makes the weight distribution of the cables more uniform, improving the stability of the drag chain during operation. The application of the snap structure 6 ensures that the drag chain will not accidentally separate during use, while retaining the necessary maintenance convenience.

[0044] In practical applications, operators can reasonably distribute cables to different corrugated pipe 5 channels according to the diameter, weight, and use of the cables. For example, power cables and signal cables can be arranged separately to reduce electromagnetic interference; heavy cables and light cables can be evenly distributed to keep the center of gravity of the drag chain stable. This design is particularly suitable for automated equipment occasions that require simultaneous installation of multiple types of cables.

[0045] Another feature of this embodiment is its modular design concept. By increasing or decreasing the number of half-tubes 4, the total number of corrugated pipe 5 channels can be flexibly adjusted to meet the needs of different application scenarios. The standardized design of the snap structure 6 also makes the assembly and maintenance of the drag chain more convenient. When a certain corrugated pipe 5 channel is damaged, the corresponding half-tube 4 component can be replaced separately without replacing the entire drag chain.

[0046] During use, when the drag chain needs to bend and move, the multiple bellows 5 channels will synchronously generate corresponding deformations. Since each channel has an independent structure, there will be no situation where the cables are entangled with each other. At the same time, the evenly distributed cable weight makes the drag chain move more smoothly during operation, reducing the risk of tipping over. This design significantly improves the reliability and service life of the drag chain under complex working conditions.

[0047] Embodiment Three:

[0048] As Figures 1 - 10 shown, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Both the first assembly 2 and the second assembly 3 are provided with multiple half pipes 4. After the half pipes 4 of the first assembly 2 are covered with the half pipes 4 of the second assembly 3, a complete bellows 5 structure is formed. The first assembly 2 and the second assembly 3 are fixedly connected through a buckle structure 6. The buckle structure 6 includes a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3, and the two cooperate with each other to achieve stable connection.

[0049] In this embodiment, the second assembly 3 is provided with the same number of half pipes 4 as the first assembly 2 to ensure that the first assembly 2 and the second assembly 3 can be completely matched to form a complete bellows 5 structure. One end of the first assembly 2 is fixedly connected to one end of the second assembly 3 through a soft belt 9. The soft belt 9 is made of a flexible material to facilitate the opening and closing of the first assembly 2 and the second assembly 3. The soft belt 9 is combined with the first assembly 2 and the second assembly 3 by a secondary molding process to ensure the firmness and durability of the connection part.

[0050] The working principle of this drag chain is as follows: Since both the first assembly 2 and the second assembly 3 are provided with multiple half pipes 4, when the two are covered, multiple independent bellows 5 channels are formed. During use, different types of cables (such as power cables, signal cables, hydraulic hoses, etc.) can be respectively arranged in different bellows 5 to avoid mutual interference and abrasion between the cables. At the same time, by reasonably distributing the cables, the center of gravity of the drag chain can be optimized to prevent problems such as tipping over or dumping of the drag chain caused by uneven cable distribution. The setting of the soft belt 9 enables the drag chain to adapt to bending deformation during movement, reduces stress concentration at the connection part, and improves the service life of the drag chain.

[0051] The drag chain structure of this embodiment is simple and easy to install, and can effectively solve the problems of cable interference, abrasion and unstable center of gravity in existing drag chains, and is suitable for cable guiding and protection applications in industrial automation equipment.

[0052] Embodiment Four:

[0053] As Figures 1 - 10As shown in the figure, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Multiple semi-tube 4 structures are provided on both the first assembly 2 and the second assembly 3. When the first assembly 2 and the second assembly 3 are covered with each other, the corresponding semi-tubes 4 will combine to form a complete corrugated pipe 5. The first assembly 2 and the second assembly 3 are fixedly connected through a buckle structure 6. The buckle structure 6 includes a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3. One end of the first assembly 2 is fixedly connected to one end of the second assembly 3 through a soft belt 9. The soft belt 9 and the first assembly 2 and the second assembly 3 are made by a secondary molding process.

[0054] In this embodiment, the first assembly 2 and the second assembly 3 are fixedly connected through at least one buckle structure 6. In particular, the ends of the first assembly 2 and the second assembly 3 are also fixedly connected through the buckle structure 6. This connection method enables the drag chain body 1 to be flexibly opened or closed according to actual needs. When it is necessary to open the drag chain body 1, the number of corrugated pipes 5 to be opened can be controlled by controlling the number of opened buckle structures 6. For example, when only some cables need to be repaired, only the buckle structure 6 at the corresponding position can be opened, without having to completely disassemble the entire drag chain, which greatly improves the convenience and efficiency of maintenance.

[0055] The working principle of this embodiment is that by setting multiple buckle structures 6, the opening and closing quantity control of the corrugated pipe 5 of the drag chain body 1 is realized. Each buckle structure 6 is equivalent to an independent connection point. When it is necessary to open the drag chain, the buckle connection at a specific position can be selectively released, so as to only open the corresponding corrugated pipe 5. This design not only facilitates the installation and maintenance of cables, but also can keep the corrugated pipes 5 in other sections closed when needed, ensuring that the protection of the cables not being repaired is not affected. At the same time, the setting of the end buckle structure 6 enhances the structural stability of the entire drag chain and prevents accidental loosening during use.

[0056] In practical applications, this design is particularly suitable for occasions where cables need to be frequently repaired or replaced. The operator can flexibly select to open some or all of the buckle structures 6 according to specific requirements to realize the control of the opening and closing degree of the drag chain.

[0057] Embodiment Five:

[0058] As Figures 1 - 10As shown, the first assembly 2 of this embodiment is provided with at least one half pipe 4. In this embodiment, the first assembly 2 is composed of multiple independent half pipe 4 units, and each half pipe 4 unit has an independent half pipe 4 structure. The second assembly 3 is designed as an integral structure, and the number of its half pipes 4 is equal to the total number of half pipes 4 of all half pipe 4 units in the first assembly 2. When the first assembly 2 and the second assembly 3 are covered, the half pipes 4 of each half pipe 4 unit in the first assembly 2 are precisely aligned with the corresponding half pipes 4 on the second assembly 3 to form a complete corrugated pipe 5 channel.

[0059] The working principle of this embodiment: By decomposing the first assembly 2 into multiple independent half pipe 4 units, the function of zone management of the cable carrier is realized. When it is necessary to repair or replace a specific cable, only the corresponding half pipe 4 unit of the first assembly 2 needs to be opened, and there is no need to disassemble the entire cable carrier structure. This design effectively avoids the problem that traditional cable carriers need to fully open all corrugated pipes 5 during maintenance, greatly reducing the risk of cable scattering. At the same time, since the second assembly 3 maintains its overall structure unchanged, the mechanical strength and stability of the entire cable carrier are ensured.

[0060] In the specific implementation process, each half pipe 4 unit of the first assembly 2 is provided with a first fastener 7 of an independent buckle structure 6, which can be locked and unlocked with the second fastener 8 on the second assembly 3 respectively. This design enables the operator to selectively open the half pipe 4 units at specific positions for maintenance operations according to actual needs. For example, when a certain cable fails, only the buckle connection of the corresponding half pipe 4 unit needs to be released, and then the cable can be repaired, while other cables still remain in the closed corrugated pipe 5 and maintain normal working conditions.

[0061] This embodiment also takes into account the wiring requirements of different cables. Since the half pipe 4 units of the first assembly 2 can be independently opened and closed, the installation and replacement of cables are more flexible and convenient. The operator can selectively open a specific number of half pipe 4 units for wiring operations according to parameters such as the diameter and quantity of the cables. This design not only improves work efficiency but also ensures that the cables are neatly arranged in the corrugated pipe 5, reducing mutual interference and wear between the cables.

[0062] From the perspective of maintenance, the design of this embodiment significantly improves the maintainability of the cable carrier. When the cables in a certain corrugated pipe 5 channel need to be maintained, only the corresponding half pipe 4 unit needs to be operated, without affecting the normal operation of other cables. This local maintenance method greatly shortens the equipment downtime and improves the operation efficiency of the production line. At the same time, since there is no need to fully open the entire cable carrier, the risk of cable damage during maintenance is also reduced.

[0063] Embodiment Six:

[0064] As Figures 1 - 10As shown, the first assembly 2 and the second assembly 3 of this embodiment are stably connected through a snap structure 6. In this embodiment, the first assembly 2 adopts a split design, including multiple independent half-tube 4 units, and first fasteners 7 are provided on both side edges of each half-tube 4 unit. These first fasteners 7 are evenly distributed along the length direction of the half-tube 4 unit to form a continuous fastening structure. The second assembly 3 is an integral structure, and the number of its half-tubes 4 is equal to the sum of the number of half-tubes 4 of all the first assemblies 2, and second fasteners 8 that are exactly matched with the first fasteners 7 are provided at corresponding positions.

[0065] The significant advantage of this embodiment is that a uniform force distribution is achieved through the fastening structure distributed at multiple points. Each fastening point bears part of the load, avoiding the problem of stress concentration. When the drag chain operates in a bent state, the fastening structure can adapt to the deformation requirements at different angles and maintain the reliability of the connection. Especially under high-speed movement or heavy-load working conditions, this distributed fastening design can effectively disperse the dynamic load and extend the service life of the drag chain.

[0066] In practical applications, this snap structure is also convenient for maintenance operations. When it is necessary to repair or replace a certain cable, only a separation force needs to be applied to the corresponding first assembly 2 unit to release the fastening connection at this local part. Since the fastenings at other parts remain intact, the cables that are not repaired can still be effectively protected. This locally detachable design greatly improves the maintenance efficiency and at the same time avoids the problem of cable chaos that may be caused by overall disassembly.

[0067] Embodiment Seven:

[0068] As Figures 1 - 10 shown, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Multiple half-tube 4 structures are provided on both the first assembly 2 and the second assembly 3. When the first assembly 2 and the second assembly 3 are covered with each other, these half-tube 4 structures can be correspondingly combined to form a complete corrugated tube 5. In order to achieve the reliable connection between the first assembly 2 and the second assembly 3, a special snap structure 6 design is adopted in this embodiment. The snap structure 6 is composed of a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3, and a fixed connection is achieved through the mutual cooperation of the two.

[0069] In this embodiment, the first assembly 2 and the second assembly 3 are fixedly connected through at least two snap structures 6. Specifically, these two snap structures 6 are respectively arranged at the two side positions of the first assembly 2 and the second assembly 3. This symmetrically arranged snap structure 6 on both sides can ensure that the first assembly 2 and the second assembly 3 maintain a stable alignment relationship during connection, preventing offset or misalignment during the connection process. After being fixed on both sides, additional snap structures 6 can be added at the middle position according to actual usage requirements to further improve the stability of the overall structure.

[0070] The design of this multi-latching structure 6 has significant advantages. First of all, the latching structures 6 fixed on both sides can ensure the connection strength of the corrugated pipe 5 in the length direction, preventing the loosening of the connection during use. Secondly, according to actual needs, the flexibility of the middle latching structure 6 is increased, making the covering of the corrugated pipe 5 in the drag chain body 1 stable. When the drag chain needs to carry heavy cables or is used in high-speed motion occasions, the number of the middle latching structures 6 can be increased, thereby improving the load-bearing capacity and stability of the overall structure.

[0071] Example Eight:

[0072] As Figures 1 - 10 shown, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Both the first assembly 2 and the second assembly 3 are provided with a plurality of half pipes 4, and the half pipes 4 of the first assembly 2 and the half pipes 4 of the second assembly 3 are covered to form a plurality of independent corrugated pipes 5. The first assembly 2 and the second assembly 3 are fixedly connected through a latching structure 6, and the latching structure 6 includes a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3.

[0073] In this embodiment, a stop structure A10 is provided on the half pipe 4 of the first assembly 2. When the drag chain body 1 is in a suspended state, the middle part of the drag chain body 1 will have a tendency to sag due to gravity. At this time, the stop structures A10 on the adjacent half pipes 4 will abut against each other to form a support framework. This support framework can effectively resist the sagging force of the drag chain body 1 and prevent the drag chain body 1 from tipping over or toppling due to the center of gravity shift.

[0074] The design of the stop structure A10 enables the drag chain body 1 to maintain stability during the rolling process. When the drag chain body 1 bends or extends, the mutual abutment of the stop structures A10 can limit the excessive deformation of the half pipe 4 and ensure the integrity of the shape of the corrugated pipe 5. This design not only improves the structural strength of the drag chain body 1 but also reduces the sway of the cables in the corrugated pipe 5, thereby reducing the friction and signal interference between the cables.

[0075] The support of the stop structure A10 enables the drag chain body 1 to still operate smoothly during high-speed motion or load changes. Due to the mutual support of the stop structures A10 on the adjacent half pipes 4, the overall rigidity of the drag chain body 1 is improved, avoiding the phenomenon of unsmooth motion or jamming caused by local deformation. This design is particularly suitable for industrial automation equipment with long-distance or high-frequency motion, and can significantly improve the operation stability and reliability of the equipment.

[0076] Example Nine:

[0077] As Figures 1 - 10As shown in the figure, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Both the first assembly 2 and the second assembly 3 are provided with multiple half pipes 4. The half pipes 4 of the first assembly 2 and the half pipes 4 of the second assembly 3 are mutually covered to form a plurality of independent corrugated pipe 5 structures. The first assembly 2 and the second assembly 3 are fixedly connected through a buckle structure 6. The buckle structure 6 includes a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3. A stop structure B11 is provided on each half pipe 4 of the second assembly 3, and these stop structures B11 play a key role when the drag chain body 1 is in a suspended state.

[0078] When the drag chain body 1 is in a suspended installation state, due to the action of gravity, the middle part of the drag chain body 1 will tend to bend downward. At this time, the stop structures B11 on adjacent half pipes 4 will abut against each other to form a continuous support skeleton. This support skeleton can effectively resist the downward deformation of the drag chain body 1 and maintain the overall shape stability of the drag chain body 1. The mutual support of the stop structures B11 enables the drag chain body 1 to operate smoothly during the rolling process and avoid problems such as poor movement caused by the downward fall of the middle part.

[0079] The design of the stop structure B11 particularly considers the use requirements of the drag chain under complex working conditions. When the equipment moves rapidly or the direction changes frequently, the drag chain body 1 is prone to shaking or lateral force. At this time, the mutual abutment of the stop structures B11 can form a stable mechanical support network, effectively preventing the drag chain body 1 from tipping over or falling. This support mechanism significantly improves the running stability of the drag chain under dynamic working conditions and ensures the safety protection of the internal cables.

[0080] In practical applications, the layout of the stop structure B11 is optimized. The stop structures B11 on adjacent half pipes 4 maintain an appropriate gap in the natural state of the drag chain body 1. When the drag chain body 1 undergoes bending deformation, these stop structures B11 can come into contact in time and form a support. This design not only ensures the flexibility of the drag chain in the straight section but also ensures the support strength in the bending section, achieving a balance between the movement performance and structural strength of the drag chain. [[ID=[]10]] [[ID=[]11]]

[0081] The support of the stop structure B11 is also reflected in the aspect of load dispersion. When the drag chain body 1 bears a large load, the mutual abutment of the stop structures B11 can disperse the concentrated load to multiple support points, avoiding deformation or damage caused by excessive local stress. This load dispersion mechanism significantly improves the load-bearing capacity of the drag chain and extends its service life.

[0082] Embodiment Ten:

[0083] As Figures 1 - 10As shown in the figure, the drag chain body 1 of this embodiment is composed of a first assembly 2 and a second assembly 3. Both the first assembly 2 and the second assembly 3 are provided with multiple semi-tubes 4. The semi-tubes 4 of the first assembly 2 and the semi-tubes 4 of the second assembly 3 are covered to form multiple independent corrugated tube 5 structures. The first assembly 2 and the second assembly 3 are fixedly connected through a buckle structure 6. The buckle structure 6 includes a first fastener 7 provided on the first assembly 2 and a second fastener 8 provided on the second assembly 3. A stop structure C12 is provided on the semi-tubes 4 on both sides of the first assembly 2. This stop structure C12 plays a key role when the drag chain body 1 is suspended.

[0084] When the drag chain is applied to occasions with a relatively light load-bearing weight. Since the light-load drag chain has relatively low requirements for structural strength and stability, this embodiment can reduce the processing cost while ensuring the basic functions. In the suspended state of the drag chain body 1, the middle area will have a downward trend due to the action of gravity. At this time, the stop structures C12 on adjacent semi-tubes 4 will abut against each other to form a continuous support framework. This support framework can effectively resist the downward deformation of the drag chain body 1 and maintain the overall shape stability of the drag chain.

[0085] The mutual abutting effect of the stop structure C12 not only prevents the excessive bending of the drag chain body 1 but also ensures the smooth movement of the drag chain during the rolling process. When the drag chain moves on the guide rail, the supporting effect of the stop structure C12 can evenly distribute the force, avoiding deformation or damage caused by local stress concentration. At the same time, this support structure can also effectively prevent the drag chain from tipping over during rapid movement or turning, significantly improving the stability and reliability of the equipment operation.

[0086] Embodiment Eleven:

[0087] As Figure 11 shown, the embodiment provides a connecting buckle for a drag chain. Among them, the first clamping plate 13 and the second clamping plate 14 form a rigid connection structure through a connecting block 15. In this embodiment, the connecting block 15 is integrally formed with the two clamping plates by an integral casting process to ensure the overall structural strength of the connecting buckle. Multiple barb 16 structures are respectively arranged on the inner surfaces of the first clamping plate 13 and the second clamping plate 14. These barbs 16 are arranged at equal intervals along the length direction of the clamping plate to form a continuous clamping tooth shape. The inclined design of the barbs 16 enables them to effectively engage into the connection holes of the drag chain body 1 and is also convenient for the sliding-in operation during installation. On the two side edges of the connecting buckle, the first clamping plate 13 and the second clamping plate 14 are symmetrically provided with convex block 17 structures. The convex blocks 17 are inserted into the corrugations of the adjacent corrugated tubes 5 to improve the connection stability of the connecting buckle.

[0088] In the first design of this embodiment, the connecting block 15 is arranged in the middle position of the first clamping plate 13 and the second clamping plate 14 to form a connecting buckle, so that the connecting port is I-shaped. When in use, the two drag chain bodies 1 are connected by the connecting buckle structure to form a whole, which is convenient for reasonably rooting the cables in different drag chain bodies 1 according to their thickness, weight and type, reducing the number of cables in a single corrugated tube 5, reducing wear between cables, preventing signal interference between cables, optimizing the distribution of cables, improving the stability of the center of gravity of the drag chain body 1, and ensuring normal operation of the equipment.

[0089] In the second design, the connecting block 15 is arranged at the connecting section of the first clamping plate 13 and the second clamping plate 14 to form a snap-on assembly in a C shape for fixing the zipper structure of the drag chain body 1 to improve the stability of the drag chain body 1 structure.

[0090] Example 12:

[0091] like Figures 12 - 15 As shown, an embodiment provides a zipper structure for a drag chain, wherein the first connecting plate 18 and the second connecting plate 19 are stably connected using a mutually cooperating clip 20 structure. The first connecting plate 18 has a plurality of protruding clips 20 evenly distributed along its length, and these clips 20 are arranged at a fixed interval to form a continuous spacing structure. The second connecting plate 19 is also provided with the same number of clips 20, but the positions of its clips 20 are staggered with the clips 20 of the first connecting plate 18. When the first connecting plate 18 and the second connecting plate 19 are interlocked, each clip 20 of the first connecting plate 18 will be embedded in the gap between two adjacent clips 20 of the second connecting plate 19, forming a mutually interlocking connection state.

[0092] In this embodiment, the staggered arrangement of the clips 20 creates a mechanical interlocking effect when the two connecting plates are connected. The clips 20 of the first connecting plate 18 abut against the side surfaces of the clips 20 of the second connecting plate 19, forming multiple points of contact. This multi-point contact distribution effectively disperses external forces, preventing excessive stress on a single connection point. When the drag chain is bent or stretched, the staggered clips 20 generate a restraining force, preventing relative slippage or separation between the connecting plates.

[0093] In practice, the clamping head 20 is designed with a beveled surface that provides guidance. When two connecting plates are brought together, the beveled surface of the clamping head 20 acts as a guide, automatically aligning the clamping head 20 and inserting it into the correct position. This self-guiding feature facilitates assembly and ensures that each clamping head 20 is accurately positioned. Once inserted, the top of the clamping head 20 forms a stopper with the contact surface of the corresponding connecting plate, preventing the connecting plates from separating vertically.

[0094] The connection structure of this embodiment exhibits good dynamic performance in the working state. When the drag chain moves reciprocally, the misaligned chucks 20 can maintain a stable contact state and will not become loose due to frequent bending actions. The interaction force between the chucks 20 will automatically adjust with the change of the bending angle of the drag chain, always maintaining an appropriate connection strength. This dynamic adaptability enables the zipper structure to adapt to various complex movement trajectories.

[0095] Embodiment Thirteen:

[0096] As Figures 12 - 15 shown, the first connecting plate 18 and the second connecting plate 19 of this embodiment are stably connected through a snap structure 6. A plurality of chucks 20 are provided on both the first connecting plate 18 and the second connecting plate 19, and these chucks 20 are arranged continuously and at intervals along the length direction of the connecting plate. The chucks 20 on the first connecting plate 18 are misaligned with the chucks 20 on the second connecting plate 19 in position, so that when the first connecting plate 18 is docked with the second connecting plate 19, the chucks 20 on the first connecting plate 18 can be aligned with the spaced areas on the second connecting plate 19, and vice versa. This misalignment design enables the chucks 20 to be embedded in each other's spaced areas to form a stable snap structure 6.

[0097] To further enhance the connection stability of the snap structure 6, a bayonet 21 is provided at the interval between the chucks 20. The design of the bayonet 21 enables the chucks 20 to form a closer fit with the bayonet 21 when they are embedded in the spaced areas of the other connecting plate. Specifically, when the chuck 20 on the first connecting plate 18 is inserted into the spaced area of the second connecting plate 19, the edge of the chuck 20 will match the shape of the bayonet 21, thereby generating an additional clamping force. This clamping force can not only prevent the chucks 20 from accidentally coming out during the operation of the drag chain, but also effectively reduce the loosening phenomenon caused by vibration or external forces.
