Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a drag chain cable for robots. Background Technology

[0002] With the deepening of Industry 4.0 and intelligent manufacturing, robots are being used more and more widely in industrial production. From automobile manufacturing and electronic assembly to food processing, robots undertake a variety of tasks such as welding, handling, and precision assembly. To power robots, drag chain cables are needed to provide them with power.

[0003] Currently, one type of robot drag chain cable in existing technology often places the cable in a cable drag chain to protect it. However, the assembly process of existing industrial robot-specific drag chain cables is relatively complex, usually using a large number of bolts to connect the cables, which leads to inconvenient assembly and is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, cables are often placed in cable drag chains to protect them. However, the assembly process of existing industrial robot drag chain cables is relatively complicated, and a large number of bolts are usually used to connect the cables, which leads to inconvenience, time and labor costs. Therefore, a drag chain cable for robots is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drag chain cable for robots, comprising a cable body, a battery core inside the cable body, an insulation layer on the outside of the battery core, a filling layer between the insulation layer and the battery core, a fireproof layer attached to the outer wall of the insulation layer, a waterproof layer attached to the outer wall of the fireproof layer, a wear-resistant layer attached to the outer wall of the waterproof layer, a collar fixed on the outer wall of the cable body, and two rings on both sides of one end of the collar, and a driving structure for driving the two rings to move in opposite directions within the collar.

[0006] Preferably, the driving structure includes a bidirectional screw disposed within the collar, with movable plates threaded to both ends of the outer wall of the bidirectional screw, and a limit post slidably connected to the ends of the two movable plates away from the bidirectional screw, with a connecting block fixed to one end of each of the two movable plates, and the ends of the two connecting blocks away from the movable plates passing through the collar and respectively fixed to the two collars.

[0007] Preferably, one end of the bidirectional screw has a built-in connecting post, and the end of the connecting post away from the bidirectional screw passes through a collar and is fixed with a hexagonal nut.

[0008] Preferably, a damping ring is installed inside the collar, the connecting post is rotatably connected to the collar through the damping ring, and the end of the bidirectional screw away from the connecting post is rotatably connected to the collar.

[0009] Preferably, both ends of the limiting post are fixed to the collar, and one end of the collar is provided with a movable groove that matches the connecting block.

[0010] Preferably, one of the collars has a retaining plate fixed to one end facing the other collar, and the other collar has a retaining groove that matches the retaining plate at one end.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, by rotating the hexagonal nut, the connecting post rotates, which in turn rotates the bidirectional screw. This causes the two moving plates to move towards or away from each other under the limitation of the limiting post, thereby causing the two collars connected to the two connecting blocks to move towards or away from each other. When it is necessary to limit the installation of the cable body, it is only necessary to move the two collars towards each other and fit them onto the cable chain through the gap between the two collars and the collar ring, achieving the effect of quickly installing the cable body. When disassembling, it is only necessary to separate the two collars, making it more practical. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a drag chain cable for robots, including a cable body 1, a battery core 2 inside the cable body 1, an insulation layer 4 on the outside of the battery core 2, a filling layer 3 between the insulation layer 4 and the battery core 2, a fireproof layer 5 attached to the outer wall of the insulation layer 4, a waterproof layer 6 attached to the outer wall of the fireproof layer 5, a wear-resistant layer 7 attached to the outer wall of the waterproof layer 6, a collar 8 fixed on the outer wall of the cable body 1, and collars 9 on both sides of one end of the collar 8. A drive structure 11 for driving the two collars 9 to move in opposite directions is provided inside the collar 8.

[0021] The overall effect of Embodiment 1 is that, through the operation of the drive structure 11, the two collars 9 can be driven to move in opposite directions. When it is necessary to limit the installation of the cable body 1, it is only necessary to move the two collars 9 in opposite directions and fit them onto the cable chain through the gap between the two collars 9 and the collar 8, thus achieving the effect of quickly installing the cable body 1. When disassembling, it is only necessary to separate the two collars 9, which is more practical. The fireproof layer 5 makes the cable body 1 fireproof, the waterproof layer 6 makes the cable body 1 waterproof, and the wear-resistant layer 7 makes the cable body 1 more wear-resistant and more practical.

[0022] Example 2, as Figure 1-4As shown, the drive structure 11 includes a bidirectional screw 1101 disposed within the collar 8. Both ends of the outer wall of the bidirectional screw 1101 are threadedly connected to movable plates 1102. The ends of the two movable plates 1102 away from the bidirectional screw 1101 are slidably connected to a limit post 1103. One end of each of the two movable plates 1102 is fixed with a connecting block 1104. The ends of the two connecting blocks 1104 away from the movable plates 1102 pass through the collar 8 and are respectively fixed to two collars 9. One end of the bidirectional screw 1101 has a built-in connecting post 13. The connecting post 13 is located away from the bidirectional screw 9. One end of the screw 1101 passes through the collar 8 and is fixed with a hexagonal nut 14. A damping ring 15 is installed inside the collar 8. The connecting post 13 is rotatably connected to the collar 8 through the damping ring 15. The end of the bidirectional screw 1101 away from the connecting post 13 is rotatably connected to the collar 8. Both ends of the limiting post 1103 are fixed to the collar 8. One end of the collar 8 is provided with a moving groove 12 that matches the connecting block 1104. One end of one collar 9 facing the other collar 9 is fixed with a retaining plate 10. One end of the other collar 9 is provided with a retaining groove 16 that matches the retaining plate 10.

[0023] The effect achieved by the entire embodiment 2 is that by rotating the hexagonal nut 14, the connecting post 13 is rotated, which in turn drives the bidirectional screw 1101 to rotate. This causes the two moving plates 1102 to move towards or away from each other under the limitation of the limiting post 1103, thereby causing the two collars 9 connected by the two connecting blocks 1104 to move towards or away from each other. When it is necessary to limit the installation of the cable body 1, it is only necessary to move the two collars 9 towards each other and fit them onto the cable chain through the gap between the two collars 9 and the collar 8, thus achieving the effect of quickly installing the cable body 1. When disassembling, it is only necessary to separate the two collars 9, which is more practical. The setting of the damping ring 15 can prevent the connecting post 13 from rotating on its own. The setting of the clamping plate 10 and the clamping groove 16 makes the docking of the two collars 9 more stable, avoiding the phenomenon of gaps leaving when the two collars 9 are docked, which would lead to unstable installation. The stability is stronger.

[0024] Working principle: When in use, the fireproof layer 5 provides fire resistance to the cable body 1, the waterproof layer 6 provides waterproof protection, and the wear-resistant layer 7 enhances its wear resistance and practicality. By rotating the hexagonal nut 14, the user rotates the connecting post 13, which in turn rotates the bidirectional screw 1101. This causes the two moving plates 1102 to move towards or away from each other under the limiting post 1103, thereby causing the two collars 9 connected to the two connecting blocks 1104 to move towards or away from each other. When the cable body 1 needs to be installed with a limiting position, it is only necessary to move the two collars 9 towards each other and fit them onto the cable chain through the gap between the two collars 9 and the collar 8, thus achieving the effect of quickly installing the cable body 1. When disassembling, it is only necessary to separate the two collars 9, which is more practical. The setting of the damping ring 15 can prevent the connecting post 13 from rotating. The setting of the clamping plate 10 and the clamping groove 16 makes the connection of the two collars 9 more stable, avoiding the phenomenon of gaps leaving when the two collars 9 are connected, which would lead to unstable installation. The stability is stronger.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
