Technical Field

[0002] With increasing automation, more and more production and living environments are adopting automated equipment. The automatic telescopic function of some connectors brings great convenience to both enterprise production lines and daily life. The connectors driven by the automatic telescopic system need to perform certain functions after extending. For example, an automatically telescopic charging head pushes the charging head to connect to the device requiring charging, enabling automatic charging; an automatically telescopic oil gun or nozzle enables automatic oiling; and an automatically telescopic fiber optic connector enables data transmission. These connectors, such as charging heads, oil guns, nozzles, and fiber optic connectors, all require connections to oil pipes, electrical wires, data cables, etc. However, many application scenarios require long telescopic distances, strong environmental adaptability, small footprint, and fast telescopic speeds, making cable storage and protection difficult to solve, leading to tangling, wear, and compression of cables. Currently, methods such as hydraulic cylinders, linear motors, lead screws, and rack and pinion systems are used. While these structures can achieve telescopic functions, they suffer from low precision, high cost, large size, and limited stroke. Furthermore, they require cable chains for cable protection and storage, further increasing space requirements. Utility Model Content

Detailed Implementation

[0027] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0028] The following embodiments can be understood as a part of the local structure or method of the present invention, or as a combination of embodiments to explain the connotation of a larger range of structures or methods of the present invention.

[0029] Example 1

[0030] A cable-guided telescopic system, such as Figure 1-12 As shown, the device includes a drive mechanism, a storage mechanism, a semi-rigid cable routing chain 01, and a flexible drive chain 02. A space 03 for cables to pass through is formed inside the cable routing chain 01. The storage mechanism includes a first storage part 04 for storing the drive chain 02 and a second storage part 05 for storing the cable routing chain. A push chain output channel 010 is formed between the first storage part 04 and the second storage part 05. The drive mechanism is located in the first storage part 04 on one side of the output channel 010 and is engaged with the drive chain 02 via a sprocket 16. The cable routing chain 01 and the drive chain 02 in the output channel mesh to form a complete push chain structure. A connector 8 is connected to the top of the push chain structure.

[0031] In this embodiment, connector 8 is used to connect the cable inside the cable routing chain to the object being pushed on the outside. Its specific structure and shape can be changed according to actual needs. The cable routing chain is a semi-rigid chain that can only bend to one side, while the drive chain is a flexible chain that can bend to both sides. When the two mesh, they form a push chain. The push chain extends and retracts under the action of the drive mechanism, realizing the movement of the object being pushed. The cable routing chain has a space 03 inside for the cable to pass through. When the push chain extends and retracts, the cable moves accordingly and is well protected.

[0032] Example 2

[0033] like Figure 8-10 As shown in Figures 1 and 12, the front and rear inner wall surfaces of the first storage section 04 are provided with multi-layered coiled first guide grooves 06, and the two ends of the pin shaft of the drive chain 02 are respectively slidably connected to the corresponding first guide grooves 06. By setting the multi-layered coiled first guide grooves, the drive chain can be fully stored in the first storage section.

[0034] like Figure 8-10 As shown in Figure 12, the bottom of the front and rear inner wall surfaces of the second storage part 05 is provided with a second guide groove 07 for cooperating with both ends of the pin 4. The top of the second storage part 05, above the second guide groove 07, is provided with a fixing groove 08 for fixing the end of the cable chain 01. Figure 10 As shown, the upper and lower ends of the inner surfaces of the front and rear walls of the second storage section 05, away from the first storage section 04, are respectively connected to horizontally arranged guide rails 011. A movable guide rail plate 012 is slidably connected between the two guide rails 011. The inner surface of the movable guide rail plate 012 is provided with a third guide rail groove 013 that mates with the second guide rail groove 07. The two ends of the pin shaft 4 are slidably connected to the third guide rail groove 013 on the front and rear sides, respectively, and during the storage and extension of the cable chain 01, it drives the movable guide rail plate 012 to move along the guide rails 011. The starting ends of the first and second guide rail grooves extend upward into the output channel. Figure 9 As shown, a structural diagram of the retracted state of this novel device is given. As the cable routing chain 01 is continuously retracted, the movable guide plate 012 moves along the guide rail 011 to the rightmost side of the second storage section; conversely, during the output of the cable routing chain, the movable guide plate 012 moves to the left along the guide rail 011.

[0035] Example 3

[0036] like Figure 1 , 2 As shown, the cable routing chain 01 includes a first outer chain plate 1 and a first inner chain plate 2 with identical structural shapes. The bottoms of the first outer chain plate 1 and the first inner chain plate 2 respectively form a first connecting part 101 and a second connecting part. The first connecting part 101 has two first connecting holes, and the second connecting part has two second connecting holes. The tops of the first connecting part 101 and the second connecting part extend upward to form a first engaging part 102 and a second engaging part, respectively. The rear ends of the first connecting part 101 and the second connecting part are respectively provided with a first protrusion 103 and a second protrusion. The front ends of the first connecting part 101 and the second connecting part are respectively provided with a first groove 104 and a second groove. The bottom of the front ends of the first engaging part 102 and the second engaging part are respectively provided with limiting teeth 014. The upper parts of the front ends of the first engaging part 102 and the second engaging part are respectively provided with a tooth structure 015. The first inner chain plate and the first outer chain plate are staggered. When the cable routing chain 01... When 1 is in a straight line state, the first groove 104 and the first protrusion 103 between adjacent first outer chain plates 1 cooperate with each other, the end of the rear limiting tooth 014 abuts against the rear end of the adjacent first meshing part 102, and the cooperation method between adjacent first inner chain plates is the same as that between adjacent first outer chain plates. In this way, a semi-rigid chain is formed, so that the cable chain can only bend to one side. The two opposite first outer chain plates 1 are connected by a pin 4. The two ends of the pin 4 are respectively interference-fitted with the opposite first connecting holes. A baffle 5 is also interference-fitted on the pin 4 outside the first connecting hole. The pin passes through the second connecting holes of the two adjacent opposite first inner chain plates 2 and is clearance-fitted with the second connecting holes. The top of the first inner chain plate 2 is also provided with a pin hole. A connecting pin 3 is connected between the two opposite pin holes. The two ends of the connecting pin 3 are respectively interference-fitted with the pin hole.

[0037] like Figure 3 , 4As shown, the drive chain 02 includes a second outer chain plate 6 and a second inner chain plate 7 with the same structural shape. The bottom of the second outer chain plate 6 and the second inner chain plate 7 respectively form a third connecting part 601 and a fourth connecting part. The top ends of the third connecting part 601 and the fourth connecting part extend upward to form a third meshing part 602 and a fourth meshing part respectively. The front ends of the third meshing part 602 and the fourth meshing part form a second meshing structure 016 that cooperates with the first meshing structure 015. The front and rear ends of the third connecting part 601 and the fourth connecting part are outwardly protruding arc-shaped protrusions. The two arc-shaped protrusions of the second outer chain plate 6 and the second inner chain plate 7 are respectively provided with a third connecting hole and a fourth connecting hole. The two opposite second outer chain plates 6 are connected by a second pin 18. The two ends of the second pin 18 are respectively clearance-fitted with the corresponding third connecting holes. The second pin passes through the fourth connecting holes of two adjacent opposite second inner chain plates 7 and is interference-fitted with the fourth connecting holes. The outer wall of the second pin, where the third connecting hole is located, is interference-fitted with a second baffle.

[0038] In this embodiment, when the drive chain and the wiring chain mesh, as follows: Figure 5 As shown, the first inner chain plate meshes with the second inner chain plate, and the first outer chain plate meshes with the second outer chain plate, thus forming a push chain with a certain rigidity.

[0039] Example 4

[0040] like Figure 8-11 As shown, the driving mechanism includes a sprocket 16 located within the first storage section. A motor shaft 15 is fixedly connected to the center hole of the sprocket 16. Both ends of the motor shaft 15 are rotatably connected to the front and rear walls of the first storage section 04, respectively. A drive motor is also located on the outside of the first storage section 04, and the output shaft of the drive motor is fixedly connected to the end of the motor shaft 15. The drive motor drives the drive chain to move. Because the drive chain and the wiring chain mesh together to form a push chain within the output channel, the push chain is driven to rise and fall.

[0041] Example 5

[0042] like Figure 5 As shown, the height of the first inner link plate 2 is greater than the height of the second inner link plate 7, and the height of the first outer link plate 1 is greater than the height of the second outer link plate 6. Figure 6 As shown, this design increases the cable capacity.

[0043] The working principle of this new type:

[0044] like Figure 1-12 As shown, the drive chain and the cable chain mesh with each other to form a rigid cylindrical structure, which, driven by the sprocket, achieves vertical lifting and retraction. Figure 9As shown, in the retracted state, the cable routing chain retracts into two layers, with the movable guide plate 012 on the outermost side. The upper layer is straight due to the chain's rigidity, and the lower layer is also straight. The tail of the cable routing chain is fixed in a groove. The drive chain retracts into three layers, stored along the first guide groove. When the push chain extends, the drive motor drives the motor shaft, which in turn drives the sprocket. The sprocket drives the drive chain, causing the cable routing chain to engage and form a push chain. Simultaneously, the bent portion of the cable routing chain in the second storage section moves to the left, causing the movable guide plate 012 to move to the left. The movable guide plate 012 maintains a fixed bending radius at the bent portion. When the movable guide plate 012 contacts the guide plate (the plate housing the second guide groove) at the left end of the second storage section, the push chain pushes the object to its maximum stroke. Figure 10 As shown. During the extension and retraction of the push chain, the cable can pass through the inside of the cable routing chain. One end of the cable is fixed to the connector, and the cable itself moves with the cable routing chain. The cable routing chain plays a role in storing and protecting the cable.
