The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0036] Please see Figure 1-5 This utility model provides a new technical solution: a safety cable, including a first cable 1, a second cable 2 installed on the front side of the first cable 1, mounting rings 3 fixedly installed on the outer surfaces of both the first cable 1 and the second cable 2, sealing gaskets fixedly connected to the opposite faces of the two mounting rings 3, a first fixing ring 4 fixedly sleeved on the outer surface of the rear mounting ring 3, a connecting ring groove 5 opened on the front side of the first fixing ring 4, four limiting slots 6 opened on the inner wall of the connecting ring groove 5, the four limiting slots 6 arranged in a ring array, a second fixing ring 7 fixedly sleeved on the outer surface of the front mounting ring 3, a connecting ring 8 fixedly connected to the rear side of the second fixing ring 7, the connecting ring 8 being adapted to the connecting ring groove 5, a fixing mechanism provided on the second fixing ring 7 and the connecting ring 8, the fixing mechanism enabling the first cable 1 and the second cable 2 to be connected together, the fixing mechanism including four insert rods 9, a first ring groove 10, four support plates 11, four sets of springs 12, a push ring 13, a push ring 14, a second ring groove 15, a control ring 16, four tension springs 17 and a disassembly ring 18.
[0037] Furthermore, four insert rods 9 are all mounted on the outer surface of the connecting ring 8, arranged in a circular array. The four insert rods 9 are adapted to four limiting slots 6. A first annular groove 10 is formed inside the connecting ring 8. The opposite ends of the four insert rods 9 slide into the interior of the first annular groove 10. Four support plates 11 are fixedly connected to the opposite ends of the four insert rods 9, and are all located inside the first annular groove 10. Four sets of springs 12 are fixedly connected to the four support plates 11, with the ends of the four sets of springs 12 that are far apart from each other fixedly connected to the inner wall of the first annular groove 10. An ejector ring 13 is slidably connected inside the first annular groove 10, contacting the opposite surfaces of the four support plates 11, and pushing the ring 14 to solidify. The push ring 14 is a conical ring, and the second ring groove 15 is opened inside the second fixed ring 7. The front side of the push ring 13 slides into the interior of the second ring groove 15. The control ring 16 is slidably connected inside the second ring groove 15. The front side of the push ring 13 is fixedly connected to the control ring 16. Four tension springs 17 are all fixedly connected to the rear side of the control ring 16. The rear ends of the four tension springs 17 are all fixedly connected to the rear wall of the second ring groove 15. The four tension springs 17 are arranged in a ring array. The tension of the four tension springs 17 is greater than the thrust of the four sets of springs 12. The disassembly ring 18 is fixedly connected to the front side of the control ring 16. The front side of the disassembly ring 18 slides through the second fixed ring 7. The disassembly ring 18 has a groove for easy pulling.
[0038] Furthermore, when starting work, if it is necessary to disconnect the connection between the first cable 1 and the second cable 2, the operator pulls the disassembly ring 18 forward. The groove on the disassembly ring 18 facilitates the operator's pulling. The disassembly ring 18 drives the control ring 16 to move forward synchronously. The control ring 16 drives the ejection ring 13 and the push ring 14 to move forward synchronously. At this time, the four tension springs 17 begin to be stretched. After the ejection ring 13 and the push ring 14 move forward, they will move to the front of the support plate 11. Then, the ejection limit of the ejection ring 13 on the four support plates 11 will be released. Then, the four sets of springs 12 will start to push the four support plates 11 to move towards the opposite side. Then, the four support plates 11 will drive the four insertion rods 9 to move synchronously. 9 will move out from inside the four limiting slots 6, thereby releasing the limiting fixation between the four plug rods 9 and the four limiting slots 6. Then the connecting ring 8 can move out from inside the connecting ring groove 5, thereby disconnecting the connection between the first cable 1 and the second cable 2. During installation, the connection between the first cable 1 and the second cable 2 can be completed in the above manner. At the same time, when the ejector ring 13 and the push ring 14 push the four support plates 11, the push ring 14 of the conical ring can more easily drive the ejector ring 13 to move between the four support plates 11. At the same time, the connection can be released by pulling the disassembly ring 18, so that even if it is accidentally touched during use, the locking and limiting state between the fixing mechanisms will not be released, thus improving the stability of the fixing mechanism during use.
[0039] Furthermore, in this way, the first cable 1 and the second cable 2 can be connected together with a simple structure. The simple structure reduces the trouble in production and manufacturing, lowers production costs, and makes maintenance more convenient when problems occur, thus improving the practicality of the cable.
[0040] Structural Description: First cable 1, second cable 2, mounting ring 3: Power can be transmitted through the first cable 1 and the second cable 2. There are two mounting rings 3, which are fixedly sleeved on the outer surfaces of the first cable 1 and the second cable 2 respectively. Sealing gaskets are fixedly connected to the opposite surfaces of the two mounting rings 3. After the first cable 1 and the second cable 2 are connected together, the opposite surfaces of the two mounting rings 3 will fit together, and the sealing gaskets will ensure the sealing of the inside of the first cable 1 and the second cable 2. The first cable 1 and the second cable 2 are the same as cable one and cable two in the prior art document with publication number CN221669159U.
[0041] First fixing ring 4, connecting ring groove 5, limiting slot 6: connection structure, the first fixing ring 4 is fixedly sleeved on the outer surface of the rear mounting ring 3, the connecting ring groove 5 is opened on the front side of the first fixing ring 4, the number of limiting slots 6 is four, all four limiting slots 6 are opened on the outer wall of the connecting ring groove 5, the four limiting slots 6 are arranged in a ring array, the connection structure can be connected with the fixing mechanism, thereby connecting the first cable 1 and the second cable 2 together;
[0042] Second fixing ring 7 and connecting ring 8: The second fixing ring 7 is fixedly sleeved on the outer surface of the front mounting ring 3, and the connecting ring 8 is fixedly connected to the rear side of the second fixing ring 7. The connecting ring 8 is adapted to the connecting ring groove 5. The second fixing ring 7 and the connecting ring 8 provide protection for the internal structure, avoid external factors from affecting it, and ensure the stability of the internal structure during use.
[0043] Insert rod 9, first annular groove 10, support plate 11, spring 12: A snap-fit structure. The first annular groove 10 is located inside the connecting ring 8. There are four insert rods 9 and four support plates 11. The four insert rods 9 are all located outside the connecting ring 8 and are arranged in a circular array. The ends of the four insert rods 9 that are far apart from each other can be fitted with four limiting slots 6 to form a snap-fit. The opposite ends of the four insert rods 9 slide into the interior of the first annular groove 10. The four support plates 11 are all located inside the first annular groove 10 and are fixedly connected to the opposite ends of the four insert rods 9. There are four sets of springs 12. The four springs 12 are fixedly connected to the four support plates 11. The ends of the four sets of springs 12 that are far apart from each other are fixedly connected to the inner wall of the first annular groove 10. By pushing with the ejector ring 13, the support plate 11 can move the insert rod 9 to the side that is far apart from each other, so that the insert rod 9 can move into the interior of the limiting slot 6 to form a snap-fit. Thus, the connecting ring 8 can be fixedly limited inside the connecting ring groove 5.
[0044] Ejector ring 13 and pusher ring 14: Pushing structure. Ejector ring 13 is slidably connected inside the first ring groove 10. Pusher ring 14 is fixedly connected to the front side of ejector ring 13. Ejector ring 13 can be adapted to support plate 11, thereby pushing the four support plates 11 to move away from each other. After transmission, the limiting and fixing of connecting ring groove 5 and connecting ring 8 can be completed. Pusher ring 14 is a conical ring structure. When the snap is released, ejector ring 13 will be in front of support plate 11. When snapping, ejector ring 13 needs to move forward. At this time, the inclined surface of pusher ring 14 will first contact support plate 11, thereby pushing support plate 11 to move away from each other, thus making it more convenient for ejector ring 13 to move forward.
[0045] Control ring 16, tension spring 17, and disassembly ring 18: These constitute the control structure. The control ring 16 is slidably connected inside the second annular groove 15. The front side of the ejector ring 13 extends slidably into the second annular groove 15, and the front end of the ejector ring 13 is fixedly connected to the control ring 16. Four tension springs 17 are fixedly connected to the rear side of the control ring 16, and the rear ends of all four tension springs 17 are fixedly connected to the rear wall of the second annular groove 15. The disassembly ring 18 is fixedly connected to the front side of the control ring 16, and the front side of the disassembly ring 18 extends slidably outwards to form a second fixing ring 7. The disassembly ring 18 has a groove. This facilitates the pulling of the disassembly ring 18 by the staff. Pulling the disassembly ring 18 forward will cause the control ring 16 to move forward synchronously, and the control ring 16 will cause the ejection ring 13 to move forward synchronously. When the ejection ring 13 moves to the front of the support plate 11, the locking limit between the insertion rod 9 and the limiting slot 6 will be released, and the connection between the first cable 1 and the second cable 2 will be broken. The tension of the four tension springs 17 is greater than the pushing force of the four sets of springs 12. After the staff releases the disassembly ring 18, the ejection ring 13 can push the four insertion rods 9 to move to the side away from each other.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
