[0022] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0024] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0025] refer to Figures 1 to 6 A cable-supporting drag chain housing assembly according to a preferred embodiment of the present invention will be described in detail below. The cable-supporting drag chain housing assembly includes a connecting unit 10 and a connected unit 20. The connecting unit 10 has multiple outer ridges 11 formed uniformly and spaced apart horizontally on the outside. Each outer ridge 11 has two slopes with opposite directions and gradients, and each outer ridge 11 is configured to form a triangular support area. The connected unit 20 is detachably connected to the inner side of the connecting unit 10 and forms a storage channel 1001 with the connecting unit 10 to store cables.

[0026] It should be noted that when the storage channel 1001 stores cables, the cables are pressed on the two end portions of the connecting unit 10 and the connected unit 20 under the action of gravity. Since the triangular support area formed by the outer spine 11 has a stable supporting effect, the connecting unit 10 and the connected unit 20 as a whole are difficult to undergo a large degree of bending deformation due to the gravity of the cables, thereby making it difficult for the drag chain shell component that can support the cables to interfere with the operation of the automated mechanical device.

[0027] In other words, the cable-supporting drag chain housing assembly can support the cable after storing the cable to maintain the storage position of the cable, thereby preventing the cable from affecting the overall deformation of the cable-supporting drag chain housing assembly due to its own weight and tending to approach the automated mechanical device.

[0028] Specifically, refer to Figure 1 and Figure 3As shown, the connecting unit 10 has a first groove 101 formed on its inner side, and the first groove 101 is configured to form at least a portion of the receiving channel 1001. In other words, when the connecting unit 10 is connected to the connected unit 20, the cable received in the receiving channel 1001 is at least partially located within the first groove 101 of the connecting unit 10.

[0029] In addition, the connecting unit 10 forms a plurality of inner ridges 12 evenly and spaced apart in the horizontal direction at the inner side, and each of the inner ridges 12 has two slopes with opposite directions and gradients, and each of the inner ridges 12 is arranged in the first groove 101 to form a triangular support area, thereby further enhancing the overall cable supporting effect of the connecting unit 10.

[0030] It is worth mentioning that the inner ridge portion 12 disposed inside the connection unit 10 reduces the contact area between the cable and the interior of the first groove 101 , thereby reducing wear between the cable and the connection unit 10 .

[0031] Preferably, the connecting unit 10 also has a plurality of support blocks 13 evenly and spaced apart in the horizontal direction at the outer position, each of the support blocks 13 is connected to one of the outer spine parts 11 and is located on the same horizontal line. In addition, each of the support blocks 13 also has an abutment portion 131 and a diameter-reducing portion 132 connected to the abutment portion 131, wherein the abutment portion 131 on each of the support blocks 13 is arranged to be spaced apart from the abutment portions 131 of adjacent support blocks 13 by a predetermined spacing, and the diameter-reducing portion 132 of each of the support blocks 13 is partially connected to the outer spine part 11, and each of the diameter-reducing portions 132 is arranged to extend toward the abutment portion 131 and gradually reduce the cross-sectional diameter.

[0032] It can be understood that when the cable drives the connecting unit 10 to bend along the outer position, on the one hand, the overall bending amplitude of the connecting unit 10 is reduced due to the supporting effect of the inner spine 12, and on the other hand, the abutment 131 of each supporting block 13 follows the bending action of the connecting unit 10 and gradually abuts against the abutment 131 of the adjacent supporting block 13, thereby limiting the overall bending degree of the connecting unit 10. As a result, the connecting unit 10 is difficult to be damaged by excessive bending, and the cable stored in the storage channel 1001 is also difficult to bend excessively because the bending degree of the connecting unit 10 is limited.

[0033] In a specific example, every two support blocks 13 are connected to the same outer spine 11 , and the two support blocks 13 on each outer spine 11 are spaced apart from each other and arranged symmetrically with respect to the outer spine 11 .

[0034] Specifically, the connected unit 20 forms a second groove 201 at an inner position, and when the connected unit 20 is connected to the connecting unit 10, the second groove 201 is arranged to communicate with the first groove 101 and form at least part of the receiving channel 1001.

[0035] It is understandable that a portion of the entire cable stored in the storage channel 1001 is located in the first groove 101 , while another portion is located in the second groove 201 .

[0036] Preferably, the connected unit 20 forms a plurality of outer ridges 21 evenly and spaced apart in the horizontal direction at the outer position, so that when the connected unit 20 bends outward, the top of each outer ridge 21 gradually abuts against each other following the overall bending action of the connected unit 20, so that the outward bending amplitude of the connected unit 20 is limited.

[0037] In a preferred embodiment, Figure 5 and Figure 6 As shown, the connected unit 20 has multiple outer ridges 21 formed uniformly and spaced apart in the horizontal direction at the outer side, and the connected unit 20 also has multiple inner ridges 22 formed uniformly and spaced apart in the horizontal direction at the inner side, and each of the inner ridges 22 is disposed in the second groove 202. Therefore, when the connected unit 20 bends inward, the top of each inner ridge 22 gradually abuts against each other following the bending movement of the connected unit 20 as a whole, thereby limiting the inward bending range of the connected unit 20. Similarly, by providing the inner ridges 22, the connected unit 20 can reduce the contact area between the cable and the inner wall forming the second groove 201, thereby reducing cable wear.

[0038] In this way, the entire bending range of the connected unit 20 can be limited.

[0039] In a modified embodiment, the connected unit 20 forms a plurality of outer ridges 21 uniformly and spaced apart in the horizontal direction at the outer position, and each of the outer ridges 21 has two slopes with opposite directions and gradients, and each of the outer ridges 21 is arranged to form a triangular support area. In addition, the connected unit 20 also forms a plurality of inner ridges 22 uniformly and spaced apart in the horizontal direction at the inner position, and each of the inner ridges 22 has two slopes with opposite directions and gradients, and each of the inner ridges 22 is arranged in the second groove 201 to form a triangular support area, so that the overall bending range of the connected unit 20 is further limited.

[0040] It is worth mentioning that in the above-mentioned modified embodiment, the connected unit 20 can be provided with a plurality of the support blocks 13 at the outer position, and each of the outer ridges 21 is provided for connection with at least one of the support blocks 13, so that when the connected unit 20 bends toward the outside, the support blocks 13 connected to the outer ridge 21 maintain a mutual abutment state through the abutment portion 131, thereby limiting the overall bending range of the connected unit 20.

[0041] In one embodiment, the connecting unit 10 extends axially at positions on both sides of the first groove 101 to form a connecting rib 14, and the connecting unit 10 is provided with multiple connecting protrusions 15 evenly and spaced apart in the horizontal direction on each connecting rib 14 for engaging with the connected unit 20. Similarly, the connected unit 20 is provided with the same number of docking ribs 23 as the connecting ribs 14 at positions adjacent to the connecting ribs 14, and the connected unit 20 is provided with the same number of docking grooves 202 as the connecting protrusions 15 evenly and spaced apart in the horizontal direction on each docking rib 23, and each docking groove 202 is configured to engage with a corresponding connecting protrusion 15.

[0042] It can be understood that when the connected unit 20 needs to be connected to the connecting unit 10, each connecting rib 14 of the connecting unit 10 is first aligned with each docking rib 23 on the connected unit 20, and each connecting protrusion 15 is correspondingly snapped into one of the docking grooves 202. At this time, the connecting unit 10 is connected to the connected unit 20, and the connecting rib 14 and the docking rib 23 are in contact with each other.

[0043] It is worth mentioning that in the above embodiment, the connecting unit 10 forms the cable-supporting drag chain shell assembly with the connected unit 20 by setting the connecting protrusion 15 and correspondingly engaging with the docking groove 202 set in the connected unit 20. Therefore, the connected unit 20 can also complete the connection purpose by setting a structure with the same function as the connecting protrusion 15 and a structure with the same function as the docking groove 202 set in the connecting unit 10.

[0044] For example, in one variant embodiment, the connected unit 20 is formed with a docking rib 23 extending axially from both sides of the second groove 201, and the connected unit 20 is provided with multiple docking protrusions 24 evenly and spaced apart horizontally on each docking rib 23 for engaging with the connecting unit 10. Similarly, the connecting unit 10 is provided with the same number of connecting ribs 14 as the docking ribs 23 at positions adjacent to the docking ribs 23, and the connecting unit 10 is provided with the same number of connecting grooves 102 as the docking protrusions 24 evenly and spaced apart horizontally on each connecting rib 14, and each connecting groove 102 is configured to engage with a corresponding docking protrusion 24.

[0045] It is understandable that the connected unit 20 is connected to the connecting unit 10 by providing the docking protrusion 24 so as to engage with the connecting groove 102 provided on the connecting unit 10 .

[0046] For example, in another variant embodiment, Figure 3 and Figure 6As shown, the connecting unit 10 extends axially at the positions on both sides of the first groove 101 to form a connecting rib 14, and the connecting unit 10 evenly and spacedly arranges a plurality of connecting protrusions 15 on each connecting rib 14 in the horizontal direction, and the connecting unit 10 also evenly and spacedly arranges a plurality of connecting grooves 102 on the connecting rib 14 in the horizontal direction. Correspondingly, the connected unit 20 forms docking ribs 23 with the same number as the connecting ribs 14 at a position close to the connecting ribs 14, and the connected unit 20 has docking grooves 202 with the same number as the connecting protrusions 15 evenly and spaced on each of the docking ribs 23 in the horizontal direction, and each of the docking grooves 202 is configured to be correspondingly engaged with one of the connecting protrusions 15. In addition, the connected unit 20 also has docking protrusions 24 with the same number as the connecting grooves 102 evenly and spaced on the docking ribs 23 in the horizontal direction, and each of the docking protrusions 24 is configured to be correspondingly engaged with one of the connecting grooves 102. Therefore, when each of the connecting protrusions 15 and each of the connecting grooves 102 on the connecting unit 10 are respectively engaged with each of the docking grooves 202 and each of the docking protrusions 24 on the connected unit 20, the connecting unit 10 and the connected unit 20 complete the connection purpose.

[0047] It should be supplemented that, in the above three embodiments of the connection between the connecting unit 10 and the connected unit 20, the connection methods of the connecting unit 10 and the connected unit 20 shown in the first two embodiments are all unilateral connections, while the connection method shown in the third embodiment is compared with the first two embodiments, in which the connecting unit 10 and the connected unit 20 are connected to each other, thereby making the connection strength between the connecting unit 10 and the connected unit 20 higher, that is, the storage channel 1001 can more stably maintain the state of being able to store cables.

[0048] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
