Description

Technical Field

[0001] This utility model relates to the field of drag chain cable technology, specifically a rotatable joint type drag chain cable. Background Technology

[0002] Drag chain cables, as an important component of high-end equipment manufacturing, are characterized by high technology content, strict usage conditions, and high added value. They are widely used in industries such as ports, mining, steel, chemicals, automobiles, logistics, petrochemicals, and packaging.

[0003] In modern industrial production, automated production lines, robots, CNC machine tools, and other equipment are widely used. These devices need to frequently move, rotate, and bend to complete various complex production tasks. To ensure the normal operation of these devices, a cable capable of stably transmitting power and signals under complex motion conditions is required.

[0004] Most existing cable carrier cables are inconvenient to disassemble, making cable maintenance difficult and limiting their practicality.

[0005] To address the aforementioned issues, a rotatable joint drag chain cable is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a rotatable joint type drag chain cable, which solves the problem that most drag chain cables in the background technology are inconvenient to disassemble, making cable maintenance difficult and impractical.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rotatable connector type drag chain cable, comprising a first chain plate, two second chain plates rotatably connected to the left sides of the two first chain plates, a connecting plate fixedly connected between the bottoms of the two first chain plates, a cable body disposed on the top of the connecting plate, a rotating component disposed on the outer side of the right end of the cable body, a cover plate disposed between the tops of the two first chain plates, positioning blocks fixedly connected to both sides of the bottom of the cover plate, a support base fixedly connected to the outer side of the first chain plate, a sliding groove opened on the top of the support base, two limiting clamps slidably connected in the sliding groove, support plates fixedly connected to both sides of the top of the support base, a pull rod penetrating and slidably connected to both support plates, an adjacent end of the two pull rods fixedly connected to the limiting clamps, a connecting rod fixedly connected to both sides of the bottom of the cover plate, and the connecting rod is disposed outside the positioning block, a limiting plug fixedly connected to the bottom of the connecting rod.

[0008] By adopting the above technical solution, by pulling the pull plate on the outer side of the first chain plate outward, the pull rod and the limiting clamp block are moved, thereby releasing the restriction on the limiting plug block, which makes it convenient for the limiting plug block to be pulled out from the two limiting clamp blocks, realizing the disassembly of the cover plate and facilitating the maintenance of the cable.

[0009] As a further description of the above technical solution: the rotating assembly includes a fixed sleeve, the inner wall of the fixed sleeve is fixedly connected to the outside of the cable body, a rotating groove is opened on the outer side of the fixed sleeve, a rotating sleeve is rotatably connected in the rotating groove, and a conductive slip ring is fixedly connected to the inner wall of the rotating sleeve.

[0010] By adopting the above technical solution, when the cable needs to rotate, the rotating sleeve can rotate freely in the rotating groove of the fixed sleeve. At the same time, the conductive slip ring can ensure the stability of the electrical connection of the cable during rotation, so as to realize the continuous transmission of power and signal.

[0011] As a further description of the above technical solution: a limiting sleeve is provided on the outside of the cable body, and the bottom of the limiting sleeve is fixedly connected to the connecting plate.

[0012] By adopting the above technical solution, the limiting sleeve prevents the cable from shaking randomly during the movement of the cable chain, ensuring that the cable's position inside the cable chain is relatively stable.

[0013] As a further description of the above technical solution: both of the first chain plates have positioning grooves on their tops, and positioning blocks are set in the positioning grooves.

[0014] By adopting the above technical solution, the stability of the cover plate installation can be ensured by inserting the positioning block into the positioning groove.

[0015] As a further description of the above technical solution: each of the two pull rods has a pull plate fixedly connected to one end facing away from the other, and the pull plate is located on the outside of the support plate.

[0016] By adopting the above technical solution, the pull plate can easily drive the movement of the pull rod.

[0017] As a further description of the above technical solution: the outer ring of the pull rod is fitted with a spring, and the spring is disposed between the support plate and the limiting clamp.

[0018] By adopting the above technical solution, the two limit clamps can be driven to move relative to each other by spring reset.

[0019] As a further description of the above technical solution: a reinforcing block is fixedly connected to the bottom of the support base, and the reinforcing block is fixedly connected to the outer side of the first chain plate.

[0020] By adopting the above technical solution, the stability of the support can be improved by using reinforcing blocks.

[0021] As a further description of the above technical solution: Limiting blocks are fixedly connected to both sides of the top of the first chain plate, and the limiting blocks are arranged on both sides of the cover plate.

[0022] By adopting the above technical solution, the limiting block can limit the movement of both sides of the cover plate.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model provides a rotatable connector type drag chain cable. Through the coordinated operation of a rotating component, a first chain plate, a cover plate, a positioning block, a positioning groove, a limiting block, a support base, a sliding groove, a limiting clamp, a support plate, and a pull rod, the rotating component enables the drag chain cable to follow the rotation of the equipment while ensuring stable power and signal transmission. Furthermore, by pulling the pull plate on the outer side of the first chain plate outward, the pull rod and the limiting clamp move, releasing the restriction on the limiting plug, thus facilitating the removal of the limiting plug from the two limiting clamps, enabling the disassembly of the cover plate, facilitating cable maintenance, and also enabling the rapid and stable installation of the cover plate.

[0030] 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.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1-4 This utility model discloses a rotatable joint type cable drag chain, comprising a first chain plate 1, with a second chain plate 2 rotatably connected to the left side of each of the two first chain plates 1. The first chain plates 1 and the second chain plates 2 form a group, and multiple groups together constitute a drag chain. In practical applications, when the moving parts of the equipment drive the drag chain to move, the first chain plates 1 and the second chain plates 2 can rotate relative to each other, thereby adapting to movement requirements in different directions and angles, ensuring that the drag chain can move synchronously with the moving parts of the equipment. A connecting plate 3 is fixedly connected between the bottom of the two first chain plates 1, and a cable body 5 is provided on the top of the connecting plate 3. A rotating component is provided on the outer side of the right end of the cable body 5, and the rotating component is connected to the rotating equipment. A cover plate 10 is provided between the top of the two first chain plates 1, and positioning blocks 11 are fixedly connected to both sides of the bottom of the cover plate 10, serving a positioning function. A support base 14 is fixedly connected to the outer side of the first chain plate 1, serving a supporting function. The top of the support base 14 has a groove 15, within which two limiting blocks 16 are slidably connected. The limiting blocks 16 can limit the movement of the limiting insert 22. Support plates 17 are fixedly connected to both sides of the top of the support base 14, providing support. Pull rods 18 are slidably connected through each of the two support plates 17, with adjacent ends of the pull rods 18 fixedly connected to the limiting blocks 16, allowing the limiting blocks 16 to move. Connecting rods 21 are fixedly connected to both sides of the bottom of the cover plate 10, and the connecting rods 21 are positioned outside the positioning block 11. A limiting insert 22, which is hemispherical, is fixedly connected to the bottom of the connecting rod 21.

[0033] Reference Figure 3 The rotating assembly includes a fixed sleeve 6, the inner wall of which is fixedly connected to the outside of the cable body 5. A rotating groove 7 is provided on the outer side of the fixed sleeve 6, and a rotating sleeve 8 is rotatably connected in the rotating groove 7. A conductive slip ring 9 is fixedly connected to the inner wall of the rotating sleeve 8. When the cable needs to rotate, the rotating sleeve 8 can rotate freely in the rotating groove 7 of the fixed sleeve 6. At the same time, the conductive slip ring 9 can ensure the stability of the electrical connection of the cable during rotation, so as to realize the continuous transmission of power and signal.

[0034] Reference Figure 1-4A limiting sleeve 4 is fitted around the cable body 5, and the bottom of the limiting sleeve 4 is fixedly connected to the connecting plate 3. The bottom of the limiting sleeve 4 has an opening to prevent the cable from shaking randomly during the movement of the cable chain and to ensure that the cable's position within the cable chain is relatively stable. Positioning grooves 12 are provided on the top of both first chain plates 1, and positioning blocks 11 are placed within the positioning grooves 12. The insertion of positioning blocks 11 into the positioning grooves 12 ensures the stability of the cover plate 10 installation. Pull plates 19 are fixedly connected to the opposite ends of both pull rods 18, and the pull plates 19 are located on the outside of the support plate 17, allowing for easy movement of the pull rods 18. A spring 20 is fitted around the outer ring of the pull rod 18, and the spring 20 is located between the support plate 17 and the limiting clamp 16. The return of the spring 20 allows for relative movement of the two limiting clamps 16. A reinforcing block 23 is fixedly connected to the bottom of the support base 14, and the reinforcing block 23 is fixedly connected to the outside of the first chain plate 1. The reinforcing block 23 improves the stability of the support base 14. Limiting blocks 13 are fixedly connected to both sides of the top of the first chain plate 1, and the limiting blocks 13 are located on both sides of the cover plate 10. The limiting blocks 13 can limit the two sides of the cover plate 10.

[0035] Working principle: When installing the cover plate 10, the cover plate 10 is placed between the two limiting blocks 13, and the two positioning blocks 11 at the bottom of the cover plate 10 are aligned and inserted into the positioning groove 12 at the top of the first chain plate 1. At this time, the two limiting inserts 22 at the bottom of the cover plate 10 are aligned and inserted between the two limiting clamps 16. When the two limiting inserts 22 are inserted into the two limiting clamps 16, the two limiting clamps 16 are squeezed and slide to both sides in the slide groove 15. The two limiting clamps 16 squeeze the spring 20 to both sides. After the limiting inserts 22 enter the two limiting clamps 16, the spring 20 returns to its original position, causing the two limiting clamps 16 to move relative to each other again to limit the limiting inserts 22. When the cable inside the drag chain needs to rotate, the rotating sleeve 8 can rotate freely in the rotating groove 7 of the fixed sleeve 6. At the same time, the conductive slip ring 9 can ensure the electrical connection of the cable is stable during rotation, realizing the continuous transmission of power and signals. By pulling the pull plate 19 on the outside of the first chain plate 1 outward, the pull rod 18 and the limit clamp 16 are moved, releasing the restriction on the limit plug 22, so that the limit plug 22 can be pulled out from the two limit clamps 16, realizing the disassembly of the cover plate 10, which facilitates the maintenance of the cable body 5.
