[0016] The beneficial effects of the present invention are as follows: by combining the spacer rod connection mechanism and the profile connection mechanism, a multi-dimensional and stable force-bearing system can be built in space through the connection between the spacer rod and the profile connecting rod and the cables in different directions. The spacer rod connection mechanism can adjust the length from its own angle and reasonably connect with the cables to disperse the stress. The profile connection mechanism further enhances the stability of the structure in different planes through the connection of two cables in mutually perpendicular directions. The cooperation of the two enables the entire cable connection device to effectively resist the influence of complex external forces, such as wind force, vibration, etc., to ensure the safety and stability of the overall structure. The design of the hardware fixing plate rotatably connected to the end of the spacer rod and the end of the profile connecting rod rotatably connected to the hardware fixing plate allows each component to adjust the angle and buffer the stress by appropriate rotation when subjected to changes in cable tension or external forces, avoiding stress concentration at a certain fixed point causing damage to the components, so that the entire device is more evenly stressed under different working conditions, has better mechanical properties, and can adapt to a variety of complex actual stress environments. Since the length of the spacer bar is adjustable and the profile connection mechanism can be connected with cables in different directions, the cable connection device can flexibly adjust the position, angle and connection method of each component when facing various engineering site layouts, space requirements and cable arrangement angles, so as to adapt to various installation scenarios, meet the personalized needs of different projects for cable connection, and improve the applicability of the device in actual engineering. Most of the components are fixed in a detachable manner, including the connection between the hardware cable fixing assembly and the hardware fixing plate, the cable and each profile cable fixing piece, and the profile connecting rod and the hardware fixing plate. After the construction personnel transport each component to the construction site separately, they can assemble and connect them in sequence according to the design requirements. The operation steps are clear and concise, which reduces the difficulty of construction, helps to improve construction efficiency, shorten the construction period, and is especially suitable for the rapid construction of large-scale projects. The detachable structural characteristics make it very convenient to carry out daily maintenance and inspection of the entire cable connection device. For example, if you want to check the status of the spacer, the connection strength of the cable and the fixings, or whether the profile connecting rod is damaged, you only need to disassemble the corresponding fixing parts for detailed inspection, without large-scale and complex disassembly of the entire device, so as to timely discover potential problems and take corresponding maintenance measures. During long-term use, if any parts such as the spacer, hardware cable fixing assembly, profile connecting rod, etc. are worn, damaged, etc. and need to be replaced, the old parts can be easily removed and new parts can be installed due to their detachable connection method, which can quickly restore the normal operation of the device, minimize the impact of component failure on the operation of the entire related system, and save maintenance costs and time. The triangular connection structure composed of the spacer, profile connecting rod and the cable arranged along the second direction has natural stability.Based on the principles of mechanics, the triangular structure can effectively disperse the tension of the cable and transfer it to each connecting component. Compared with connection structures of other shapes, it can better resist the effects of external forces, reduce the possibility of structural deformation, and improve the stability and reliability of the entire cable connection system when subjected to various loads (such as wind loads, deadweight loads, live loads, etc.).

[0067] Embodiment eight:

[0068] Based on some of the above embodiments or embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 or embodiment 5 or embodiment 6 or embodiment 7 or embodiment 8, a cable connection structure of a cable connection device is provided: Figure 1 As shown, it includes a cable 300, a hardware fixing plate 102.2 is detachably fixed at both ends of the spacer bar 101, a set of hardware cable fixing components 102.1 can be detachably fixed on each hardware fixing plate 102.2, and each set of hardware cable fixing components 102.1 can be detachably fixedly connected with a cable 300; the first profile cable fixing members 202.1 located at both ends of the profile connecting rod 201 are respectively fixed with a cable 300 arranged along the first direction, and the second profile cable fixing members 202.2 located at both ends of the profile connecting rod 201 are respectively fixed with a cable 300 arranged along the second direction; one end of the profile connecting rod 201 is detachably fixed to the hardware fixing plate 102.2 located at one end of the spacer bar 101; the spacer bar 101, the profile connecting rod 201 and the cable 300 arranged along the second direction form a triangular connection structure.

[0069] In summary, the present invention combines the spacer rod connection mechanism 100 and the profile connection mechanism 200, and can build a multi-dimensional and stable force system in space through the connection between the spacer rod 101 and the profile connecting rod 201 and the cables 300 in different directions. The spacer rod connection mechanism 100 can adjust the length from its own angle and reasonably connect with the cable 300 to disperse the stress. The profile connection mechanism 200 is connected by two cables 300 in perpendicular directions to further enhance the stability of the structure in different planes. The cooperation of the two enables the entire cable connection device to effectively resist the influence of complex external forces, such as wind, vibration, etc., to ensure the safety and stability of the overall structure. The design that the hardware fixing plate 102.2 is rotatably connected to the end of the spacer bar 101 and one end of the profile connecting rod 201 is rotatably connected to the hardware fixing plate 102.2 allows each component to adjust the angle and buffer the stress by appropriate rotation when subjected to the tension change of the cable 300 or the action of external force, so as to avoid stress concentration at a certain fixed point causing damage to the component, so that the entire device is more evenly stressed under different working conditions, has better mechanical properties, and can adapt to a variety of complex actual stress environments. Since the length of the spacer bar 101 is adjustable and the profile connecting mechanism 200 can be connected to the cables 300 in different directions, when faced with various different project site layouts, space requirements, and cable arrangement angles, the cable connection device can flexibly adjust the position, angle, and connection method of each component to adapt to a variety of installation scenarios, meet the personalized needs of different projects for cable connections, and improve the applicability of the device in actual engineering. Most of the components are fixed in a detachable manner, including the connection between the hardware cable fixing assembly 102.1 and the hardware fixing plate 102.2, the cable 300 and each profile cable fixing piece, and the profile connecting rod 201 and the hardware fixing plate 102.2. Construction personnel can transport each component to the construction site separately, and assemble and connect them in sequence according to the design requirements. The operation steps are clear and concise, which reduces the construction difficulty, helps to improve construction efficiency, shorten the construction period, and is especially suitable for the rapid construction of large-scale projects. The detachable structural feature makes it very convenient to carry out daily maintenance and inspection of the entire cable connection device. For example, if you want to check the status of the spacer bar 101, the connection strength of the cable 300 and each fixing piece, or whether the profile connecting rod 201 is damaged, you only need to disassemble the corresponding fixing part for detailed inspection, without large-scale and complex disassembly of the entire device, so as to find potential problems in time and take corresponding maintenance measures. During long-term use, if any components such as the spacer bar 101, the hardware cable fixing assembly 102.1, the profile connecting rod 201, etc. are worn, damaged, etc. and need to be replaced, the old components can be easily removed and new components can be installed due to their detachable connection method, which can quickly restore the normal operation of the device, minimize the impact of component failure on the operation of the entire related system, and save maintenance costs and time.The triangular connection structure composed of the spacer bar 101, the profile connecting rod 201 and the cable 300 arranged along the second direction has natural stability. In terms of mechanical principles, the triangular structure can effectively disperse and transfer the tension of the cable to each connecting component. Compared with connection structures of other shapes, it can better resist the action of external forces, reduce the possibility of structural deformation, and improve the stability and reliability of the entire cable connection system when bearing various loads (such as wind load, deadweight load, live load, etc.).
