Description

Technical Field

[0001] This invention relates to the field of optical cable installation technology. Specifically, it relates to a quick-release and fixing structure for temperature-measuring optical cables. Background Technology

[0002] In fields such as power transmission and communication network construction, cable trays serve as the core support structure for cable laying and are widely used in substations, data centers, industrial plants, and other scenarios. With the increasing demand for equipment operation safety monitoring, temperature-sensing optical cables, as precise and real-time temperature sensing elements, are being deployed extensively in cable trays to monitor temperature changes at cable joints and in densely laid areas, providing timely warnings of overheating faults and ensuring the stable operation of power or communication systems. The fixing structure of the temperature-sensing optical cables to the cable trays directly affects the installation efficiency, ease of maintenance, and long-term operational reliability of the optical cables, making it a key aspect that urgently needs optimization within the industry.

[0003] Currently, the mainstream method for fixing temperature-measuring optical cables to cable trays in the industry is a combination of screws and cable ties. This method uses metal screws to fasten the fixing bracket to the side plate of the cable tray, and then uses nylon cable ties to bind the temperature-measuring optical cable to the bracket. This method has the following main problems: First, it has low assembly and disassembly efficiency. The assembly and disassembly time for a single fixing point in the traditional structure is generally more than 3 minutes, which seriously affects the construction progress in large-scale temperature-measuring optical cable laying or emergency maintenance scenarios. Second, it has poor reusability. The single-use nature of consumables such as cable ties and disposable clips not only increases maintenance costs but also generates a large amount of solid waste, which is inconsistent with the industry's green and environmentally friendly development trend. Third, it presents a contradiction between fixing reliability and operational convenience, making it difficult to achieve a balance between the two.

[0004] In summary, existing fixing structures for temperature-sensing optical cables and cable trays generally suffer from problems such as reliance on tools, cumbersome assembly and disassembly, non-reusability, poor adaptability, and insufficient fixing reliability. These issues restrict the installation and maintenance efficiency of temperature-sensing optical cables and increase system operation risks and maintenance costs. Therefore, developing a fixing structure that requires no tools, allows for quick assembly and disassembly, is reusable, highly adaptable, and provides reliable fixing has become an urgent need in the industry. Summary of the Invention

[0005] The purpose of this invention is to provide a quick assembly and disassembly structure for temperature-measuring optical cables, solving the problems of existing optical cable fixing structures that are "tool-dependent, slow to assemble and disassemble, and not reusable", and achieving the triple requirements of "tool-free quick assembly and disassembly + reusability + secure fixing".

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A quick-release and fixing structure for a temperature-measuring optical cable, characterized in that it includes a cable tray fixing component and a temperature-measuring optical cable fixing buckle; The cable tray fixing component includes a fixing component body, and the temperature measuring optical cable fixing buckle includes a built-in spring structure and a central rod that is slidably connected to the fixing component body; by compressing or releasing the spring, the cable tray side plate can be clamped or released. The temperature-measuring optical cable fixing buckle is connected to the cable tray fixing component. It includes a buckle body and an optical cable threading hole. The inner wall of the optical cable threading hole has a movable inner wall with an elastic latch at its end. The cable tray fixing component or buckle body is provided with a slot that matches the elastic latch. The temperature-measuring optical cable is fixed by the detachable engagement of the elastic latch with the slot. By pressing and pulling, the elastic latch is disengaged from the slot, and the optical cable threading hole can be opened to remove the temperature-measuring optical cable.

[0007] Based on the above technical solutions, the present invention may also employ the following further technical solutions, or combine these further technical solutions: The fastener body has a channel-shaped cross-section and is made of 304 stainless steel.

[0008] The spring is made of 304 stainless steel, with a natural length of 30-35mm and a maximum compressed length of 15-20mm, and is compatible with cable tray side plates with a thickness of 1-17mm.

[0009] The inner end of the center rod is located within the groove of the fixing body and connected to the clamping plate, while the other end is located outside the groove of the fixing body and connected to the handle. The handle or the clamping plate and the center rod are detachably connected. The center rod can slide within the fixing body. Based on a spring, and through the cooperation of the clamping plate and the groove wall of the fixing body, the clamping or detachment operation of the cable tray side plate is achieved. Both the center rod and the clamping plate are made of 304 stainless steel.

[0010] The diameter of the optical cable threading hole is 4-8mm, which is suitable for temperature measuring optical cables with an outer diameter of 3-7mm.

[0011] The optical cable threading hole is located on the front of the buckle body. The movable inner wall is rotatably connected to the buckle body and can be rotated away from the buckle body to open the optical cable threading hole.

[0012] The elastic latch includes an elastic pressure plate, on which an inner snap-fit ​​structure and an outer snap-fit ​​structure adapted to the slot wall are provided.

[0013] The back of the buckle body is also provided with a body buckle, and the fastener body is provided with a second slot that is adapted to the body buckle. The body buckle and the second slot can be detachably snapped together.

[0014] The central rod and the temperature measuring optical cable fixing buckle are located at different height positions of the cable tray fixing component.

[0015] The cable tray fixing components are galvanized, and the temperature measuring optical cable fixing buckles are made of wear-resistant polytetrafluoroethylene plastic.

[0016] The beneficial effects of this invention are: (1) It enables tool-free and rapid operation throughout the entire assembly and disassembly process, allowing for the pressing and pulling of the temperature measuring optical cable for fixing and removal. It also allows for the assembly and disassembly of the temperature measuring optical cable fixing clips without the need for screwdrivers, wrenches, or other tools, resulting in high assembly and disassembly efficiency. (2) Both the cable tray fixing body and the temperature measuring optical cable fixing clips can be made of fatigue-resistant materials, ensuring high reusability and reducing maintenance costs.

Detailed Implementation

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] Referring to the accompanying drawings, the present invention provides a quick-release and fixing structure 2 for a temperature-measuring optical cable, comprising a cable tray fixing component and a temperature-measuring optical cable fixing buckle 22.

[0020] The cable tray fixing component includes a fixing body 21, and the temperature measuring optical cable fixing buckle 22 includes a built-in spring structure and a central rod 213 that is slidably connected to the fixing body 21. By compressing or releasing the spring 212, the cable tray side plate can be clamped or released and fixed to the side plate of the cable tray 1.

[0021] The temperature-measuring optical cable fixing buckle 22 is connected to the cable tray fixing body 21. It includes a buckle body 220 and an optical cable threading hole 224. The inner wall of the optical cable threading hole 224 has a movable inner wall 2241, with an elastic latch 221 at its end. The cable tray fixing body 21 has a slot 216 that matches the elastic latch 221. The temperature-measuring optical cable 3 is fixed by the detachable engagement of the elastic latch 221 with the slot 216. By pressing and pulling, the elastic latch 221 is disengaged from the slot 216, opening the optical cable threading hole 224 and allowing the temperature-measuring optical cable 3 to be removed.

[0022] The fastener body 21 has a rectangular groove in cross-section. It is made of 304 stainless steel.

[0023] The spring 212 is made of 304 stainless steel and is fitted onto the central rod 213. The natural length of the spring 212 is 30-35mm, the maximum compressed length is 15-20mm, and it is suitable for cable tray side plates with a thickness of 1-17mm.

[0024] The inner end of the central rod 213 is located within the groove of the fixing body 21 and connected to the clamping plate 214, while the other end is located outside the groove of the fixing body and connected to the handle 215. The handle and the central rod are detachably connected (e.g., by thread). The central rod 213 can slide within the fixing body. Based on the spring 212, and through the cooperation of the clamping plate 214 and the groove wall 211 of the fixing body 21, the clamping or detachment operation of the quick-release fixing structure 2 for the temperature measuring optical cable against the cable tray side plate is achieved without tools. Both the central rod and the clamping plate are made of 304 stainless steel.

[0025] The central rod 212 and the temperature measuring optical cable fixing buckle 2 are located at different height positions of the cable tray fixing component.

[0026] The diameter of the optical cable threading hole 224 is 4-8mm, which is compatible with the temperature measuring optical cable 3 with an outer diameter of 3-7mm.

[0027] The optical cable threading hole is located on the front of the buckle body 220. The movable inner wall 2241 is rotatably connected to the buckle body 220 and can be rotated away from the buckle body 220 to open the optical cable threading hole 224.

[0028] The elastic latch 221 includes an elastic pressure plate 2210. The elastic pressure plate is provided with an inner latching structure 2211 and an outer latching structure 2212 that are adapted to the wall of the latch groove. The outer latching structure 2212 can be made larger so that the elastic latch 221 can be pushed and pulled by hand.

[0029] The back of the buckle body 220 is also equipped with buckles, including a body buckle 222 on the left and a body buckle 223 on the right. The groove wall 211 of the fixing body 21 is provided with slots 217 and 218 that are adapted to the body buckles 222 and 223. The body buckles 222 and 223 are detachably engaged with the slots 217 and 218 respectively. This allows for tool-free, detachable, and quick connection between the buckle body 220 and the fixing body 21, while the elastic latch 221 provides a more secure fixation of the temperature-measuring optical cable fixing buckle 22. The detachable and quick connection between the elastic latch 221 and the fixing body 21 reduces the overall number of buckles in the temperature-measuring optical cable fixing buckle 22. Simultaneously, tool-free, quick installation and removal of the temperature-measuring optical fiber is possible even when the temperature-measuring optical cable fixing buckle 22 is fixed to the fixing body 21.

[0030] The cable tray fixing components are galvanized, and the temperature measuring optical cable fixing buckles are made of wear-resistant polytetrafluoroethylene plastic. The temperature measuring optical cable fixing buckle 22, including the buckle body 220, the elastic tab 216, and the body buckles 222 and 223, can be made of sheet metal processing such as punching and bending of steel plates. The elastic tab 216 and the body buckles 222 and 223 have corresponding elasticity and can be squeezed and reset.

[0031] The following combination Figures 1-4 The specific process of disassembling and assembling the present invention is described as follows: First, a quick-release and fixing structure 2 for the temperature-measuring optical cable of the present invention is placed at intervals (e.g., 0.5 meters) along the left and right side plates of the cable tray 1. The quick-release and fixing structure 2 for the temperature-measuring optical cable clamps or detaches from the side plates of the cable tray by compressing or releasing springs.

[0032] Next, the temperature-measuring optical cable 3 is laid along the cable tray 1. The temperature-measuring optical cable 3 is fixed to the quick-release and fixing structure 2 of the temperature-measuring optical cable by the temperature-measuring optical cable fixing clip 22. Specifically, pressing the elastic tab 221 causes it to be inserted into the slot 216, and releasing it achieves a locking connection, thus fixing the temperature-measuring optical cable; pressing and pulling the elastic tab 221 causes it to be released from the slot 216, which opens the optical cable threading hole 224, allowing the temperature-measuring optical cable 3 to be removed.

[0033] When the temperature measuring optical cable fixing clip 22 reaches the end of its service life or needs to be replaced for other reasons, it can be removed by pressing and pulling the elastic tab 221 and pressing the body clips 222 and 223 to disengage them from the slots 216, 217 and 218 respectively. When a new temperature measuring optical cable fixing clip 22 needs to be installed, it can be fixed to the cable tray fixing component 21 by pressing and pushing the elastic tab 221 and the body clips 222 and 223. This allows for quick disassembly and assembly without the need for screwdrivers or other tools.

[0034] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be determined by the claims.
