Description

Technical Field

[0001] This utility model relates to the field of dust-free cable chain technology, specifically to an open-type dust-free cable chain that facilitates cable threading. Background Technology

[0002] Cleanroom cable chains are cable protection devices specifically designed for clean environments and are widely used in industries with extremely high cleanliness requirements, such as semiconductors, medical devices, and food processing. Their enclosed structure effectively prevents the spread of dust and debris generated during cable operation, ensuring a clean environment. Made from wear-resistant, low-dust-generating materials, they operate smoothly with low noise and are easy to maintain, making them a key component in high-end manufacturing.

[0003] Traditional one-piece chain links require disassembling the ends and threading them one by one, which is time-consuming and easily introduces particles. Over long strokes, they are more prone to bending due to their own weight, generating dust by rubbing against the chain wall. Although some open structures can release the cable laterally, they lack positioning and rigid support. After threading, the chain links are prone to springing back and misalignment, requiring repeated correction. Over long strokes, there is no extension support, causing the drag chain to sag and bend, increasing friction between the cable and the chain wall, making it inconvenient to perform threading work. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an open-type dust-free cable chain for convenient cable threading, including an open-type dust-free cable chain body. The bottom of the open-type dust-free cable chain body is engaged with a locking platform. The front end of the locking platform has a through hole, and a limit tube is sleeved inside the through hole. The left end of the locking platform has a threaded hole one, and an internal hex bolt is threaded into the threaded hole one. The top of the locking platform is fixedly connected to a connecting platform, and a top plate is slidably connected to the surface of the connecting platform. A screw is sleeved on the top of the top plate, and the top of the locking platform has a threaded hole two.

[0005] Through the above technical solution, by setting up an open-type card plate-top plate combination, the open-type dust-free cable chain body is quickly pressed and positioned using the connecting table slide groove and screws, and a retractable rigid longitudinal support is formed by the limit tube-extension rod. This allows the cable laying, pressing and straightening to be completed in one go without disassembling the cable chain, avoiding the problem of the dust-free cable chain bending and making it difficult to perform the pipe threading work during the pipe threading process.

[0006] As a further improvement to the above solution, two card stations are provided, and the two card stations are evenly distributed on the surface symmetrically around the top center of the open-type dust-free cable chain body, and the front end of the threaded hole is connected to the through hole.

[0007] The above technical solution ensures that the symmetrical arrangement of the two card platforms evenly distributes the weight of the cable chain and the internal cable, preventing one side from tilting up.

[0008] As a further improvement to the above solution, two connecting platforms are provided, and the two connecting platforms are symmetrically distributed around the center of the top of the card platform.

[0009] Through the above technical solution, the dual connecting platform provides four-point sliding guidance, and the force is symmetrical when the top plate is pressed down, avoiding the risk of micro-cracks in the plastic chain links caused by single-point over-positioning.

[0010] As a further improvement to the above solution, the number of screws is set to four, and the four screws are symmetrically and evenly distributed around the center of the top of the top plate. The screws penetrate the top plate and are threaded into the inside of the threaded hole two.

[0011] With the above technical solution, the four screws are arranged in a rectangular shape, which presses the top plate evenly against the upper surface of the chain link and fixes it stably.

[0012] As a further improvement to the above solution, a threaded rod is fixedly connected to the front end of the limiting tube, and an extension rod is threadedly connected to the surface of the threaded rod.

[0013] Through the above technical solution, the detachable structure of the threaded rod-extension rod allows the length of the limiting tube to be extended proportionally to the length of the cable chain without tools on site.

[0014] As a further improvement to the above solution, the two ends of the threaded rod pass through through holes, and the extension rod has the same radius as the limiting tube.

[0015] As a further improvement to the above solution, a sliding groove is provided on the top of the connecting platform, and a slider is slidably connected inside the sliding groove.

[0016] Through the above technical solution, the sliding groove-slider pair constrains the opening and closing motion of the top plate to a pure linear line, preventing lateral displacement from damaging the plastic chain.

[0017] As a further improvement to the above solution, two slides are provided, which are symmetrically distributed around the center of the top of the connecting platform, and the end of the slider away from the slide is fixedly connected to the inner wall of the top plate.

[0018] Through the above technical solution, the symmetrical arrangement of the double slide grooves enables the top plate to stably limit and press the dust-free cable chain when it is subjected to locking force, thus avoiding cantilever deformation.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model sets up an open-type card plate-top plate combination, uses the connecting table slide groove and screws to quickly press and position the open-type dust-free cable chain body, and uses the limiting tube-extension rod to form a retractable rigid longitudinal support, so as to complete the laying, pressing and straightening in one go without disassembling the cable chain, and avoid the dust-free cable chain bending during the pipe threading process, which makes it difficult to carry out the pipe threading work.

[0021] This utility model, by setting a lateral locking pair of through hole, threaded hole and internal hex bolt, allows the limiting tube to be radially locked by one hand after any length adjustment. During operation, the limiting tube has no risk of rotation and loosening when the drag chain reciprocates, thus achieving the goal of maintaining high coaxiality under long stroke conditions.

[0028] Example:

[0029] Please combine Figure 1-4 This embodiment of an open-type dust-free cable chain for easy cable threading includes an open-type dust-free cable chain body 1. A locking platform 2 is snapped into the bottom of the open-type dust-free cable chain body 1. A through hole 3 is opened at the front end of the locking platform 2. A limit tube 4 is sleeved inside the through hole 3. A threaded hole 5 is opened at the left end of the locking platform 2. An internal hex bolt 6 is threaded into the threaded hole 5. A connecting platform 9 is fixedly connected to the top of the locking platform 2. A top plate 11 is slidably connected to the surface of the connecting platform 9. A screw 13 is sleeved on the top of the top plate 11. A threaded hole 14 is opened on the top of the locking platform 2.

[0030] In use, the open-type cleanroom cable chain body 1 is snapped onto the inner wall of the open-type cleanroom cable chain body 1. Then, the top plate 11 is slidably connected to the surface of the connecting platform 9, and the screw 13 is screwed into the threaded hole 14 to initially limit the position of the open-type cleanroom cable chain body 1. The limiting tube 4 is fitted into the through hole 3, and the internal hex bolt 6 is threaded into the threaded hole 5, so that the front end of the threaded hole 5 contacts the surface of the limiting tube 4 to fix the limiting tube 4. At this time, the positions of the two clamping platforms 2 are limited to vertical, so as to prevent the open-type cleanroom cable chain body 1 from bending during the tube insertion process.

[0031] There are two card stations 2. The two card stations 2 are evenly distributed on the surface with the top center of the open-type dust-free cable chain body 1 symmetrically. The front end of the threaded hole 5 is connected to the through hole 3.

[0032] There are two connecting platforms 9, which are symmetrically distributed around the top center of the card platform 2.

[0033] There are four screws 13. The four screws 13 are symmetrically and evenly distributed around the top center of the top plate 11. The screws 13 pass through the top plate 11 and are threaded into the inside of the threaded hole 14.

[0034] The front end of the limiting tube 4 is fixedly connected to a threaded rod 7, and an extension rod 8 is threadedly connected to the surface of the threaded rod 7. The bottom of the extension rod 8 is threadedly connected to the inside of the threaded rod 7 to extend the length of the entire limiting tube 4.

[0035] Both ends of the threaded rod 7 pass through the through hole 3, and the extension rod 8 has the same radius as the limiting tube 4.

[0036] The top of the connecting platform 9 is provided with a slide groove 10, and a slider 12 is slidably connected inside the slide groove 10.

[0037] There are two slides 10, which are symmetrically distributed around the top center of the connecting platform 9. The end of the slider 12 away from the slide 10 is fixedly connected to the inner wall of the top plate 11.

[0038] The implementation principle of the convenient wire threading open-type cleanroom cable chain in this application embodiment is as follows: When the cleanroom cable chain is threaded, the open-type cleanroom cable chain body 1 is first snapped onto the inner wall of the clamping platform. Then, the top plate 11 is slidably connected to the surface of the connecting platform 9, and the screw 13 is screwed into the threaded hole 14 to initially limit the position of the open-type cleanroom cable chain body 1. The limiting tube 4 is sleeved into the through hole 3, and the internal hex bolt 6 is threaded into the threaded hole 5, so that the front end of the threaded hole 5 contacts the surface of the limiting tube 4 to fix the limiting tube 4. At this time, the positions of the two clamping platforms 2 are limited to vertical to prevent the open-type cleanroom cable chain body 1 from bending. Then, the wire is passed from the output end of the open-type cleanroom cable chain body 1 into its interior.

[0039] When the length of the open-type dust-free cable chain body 1 is too long, the bottom of the extension rod 8 is threaded into the inside of the threaded rod 7 to extend the length of the overall limiting tube 4.

[0040] After the wire passes through the interior of the open-type dust-free cable chain body 1, tighten the screw 13 to complete the wiring process.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
