[0001] This utility model relates to the field of cable fixing technology devices, and in particular to a cable anti-pull fixing device for chemical instruments. Background Technology

[0002] In industries such as chemical, petroleum, and energy, instrument cables are the "nerve vessels" connecting field instruments to control systems, ensuring accurate data transmission and effective execution of control commands. The standardization and reliability of their wiring directly affect the safety, stability, and long-term operation of the entire production unit.

[0003] Traditional cable fixing devices mostly use cable ties. However, cable ties can be too tight and damage the cable insulation, or too loose and cause the cable to come loose. When a specific cable needs to be repaired, the cable ties must be cut, which is cumbersome and cannot be reused. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a cable anti-pull fixing device for chemical instruments, which can effectively prevent multiple cables from crossing and tangling, making the layout neater and more standardized.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cable anti-pull fixing device for chemical instruments includes a fixing plate. A drive assembly is provided on the upper left side of the fixing plate. A third drive shaft is fixedly connected to the upper middle part of the fixing plate. Both the upper and lower ends of the third drive shaft are rotatably connected to drive frames. A movable clamping plate is fixedly connected to the outside of the third drive shaft between the two drive frames. A second drive shaft is fixedly connected to both the front and rear ends of the drive frames. A fixed clamping plate is rotatably connected to the outer side of the rear end of the second drive shaft. An auxiliary rod is installed on the upper right side of the fixing plate. An auxiliary groove is opened on the upper right side of the fixing plate. A movable rod is movably connected inside the auxiliary groove.

[0006] Furthermore, the drive assembly includes a drive slide rail located at the left end of the fixed plate, a drive slider is slidably connected inside the drive slide rail, a drive shaft is fixedly connected to the upper side of the drive slider, and a fixing bolt is provided inside the drive shaft.

[0007] Furthermore, a drive arm is rotatably connected to the outside of the drive shaft, a pull rope is fixedly connected to the left end of the drive arm, and a first transmission shaft is rotatably connected to the middle of the drive arm.

[0008] Furthermore, both the upper and lower ends of the first drive shaft are rotatably connected to drive arms, and the rear end of the drive arms is rotatably connected to the left end of the fixed clamping plate.

[0009] Furthermore, a first rubber gear is provided on the right side of the movable clamping plate, and a second rubber gear is provided on the left side of the fixed clamping plate.

[0010] Furthermore, a support rod is provided at the lower end of the movable rod, and the front and rear ends of the support rod are fixedly connected to the inside of the fixed plate.

[0011] Furthermore, a spring is provided on the outer rear end of the support rod, the rear end of the spring is fixedly connected to the inside of the fixed plate, and the lower end of the spring is fixedly connected to the rear side of the movable rod.

[0012] Furthermore, both the movable rod and the auxiliary rod have grooves on their outer surfaces.

[0013] This utility model has the following beneficial effects: In this invention, the operator can control the clamping force of the movable clamping plate on the cable by controlling the tension of the pull rope. This ensures a secure fixation while preventing excessive compression that could deform the cable or damage the insulation layer. It also provides a large clamping stroke, allowing it to accommodate cables of different diameters within a certain range.

[0014] In this invention, the cable passes through the middle of the auxiliary rod and wraps around the side of the movable rod to form an arc shape, making the path of each cable clearly visible.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 An embodiment of this utility model provides a chemical instrument cable anti-pull fixing device, including a fixing plate 1, a drive slide rail 2 opened at the left end of the fixing plate 1, a drive slider 3 slidably connected inside the drive slide rail 2, a drive shaft 4 fixedly connected to the upper side of the drive slider 3, a fixing bolt 6 provided inside the drive shaft 4, a drive arm 7 rotatably connected to the outside of the drive shaft 4, a pull rope 5 fixedly connected to the left end of the drive arm 7, a first transmission shaft 8 rotatably connected to the middle of the drive arm 7, a transmission arm 13 rotatably connected to the upper and lower ends of the first transmission shaft 8, the rear end of the transmission arm 13 rotatably connected to the left end of the fixed clamping plate 18, a first rubber gear 17 provided on the right side of the movable clamping plate 16, and a second rubber gear 19 provided on the left side of the fixed clamping plate 18.

[0019] The operator can control the tension of the pull rope 5 to drive the drive shaft 4 and drive slider 3 to slide inside the drive slide rail 2, thereby driving the first drive shaft 8 and the second drive shaft 9 on the left to rotate. Through the operation of the drive arm 13 and the back-and-forth swing of the drive frame 14 around the third drive shaft 15, the fixed clamping plate 18 is moved. Then, by controlling the clamping degree of the fixed clamping plate 18 on the cable, it can ensure that the cable is firmly fixed and avoid excessive compression that could cause cable deformation or insulation damage. It can provide a large clamping stroke, so that it can adapt to cables of different diameters within a certain range. When it is moved to a suitable position, the drive shaft 4 is fixed by rotating the fixing bolt 6 to ensure the stability of the cable clamping.

[0020] Reference Figures 1-3A third drive shaft 15 is fixedly connected to the upper middle part of the fixed plate 1. Both the upper and lower ends of the third drive shaft 15 are rotatably connected to the external parts of the drive frame 14. A movable clamping plate 16 is fixedly connected to the external part of the third drive shaft 15 between the two drive frames 14. Both the front and rear ends of the drive frame 14 are fixedly connected to the second drive shaft 9. A fixed clamping plate 18 is rotatably connected to the outer side of the rear end of the second drive shaft 9. An auxiliary rod 20 is installed on the upper right side of the fixed plate 1. An auxiliary groove 21 is opened on the upper right side of the fixed plate 1. A movable rod 11 is movably connected inside the auxiliary groove 21. A support rod 10 passes through the lower end of the movable rod 11. Both the front and rear ends of the support rod 10 are fixedly connected to the inside of the fixed plate 1. A spring 12 is provided on the external part of the rear end of the support rod 10. The rear end of the spring 12 is fixedly connected to the inside of the fixed plate 1. The lower end of the spring 12 is fixedly connected to the rear side of the movable rod 11. Grooves are opened on the external parts of the movable rod 11 and the auxiliary rod 20.

[0021] The cable passes through the middle side of the auxiliary rod 20, wraps around the side of the movable rod 11, and then passes through the side of the rear auxiliary rod 20, forming an arc shape. This makes the path of each cable clearly visible, which greatly facilitates daily inspection, fault diagnosis, and line tracing for complex instrument circuits. It can effectively prevent multiple cables from crossing or tangling, making the layout neater and more standardized. When the cable is pulled to apply external force, the movable rod 11 slides to the left under the action of external force, so that the cable is on a horizontal line, which is convenient for the operator to carry out subsequent operations. When the external force is removed, the spring 12 drives the movable rod 11 to return to its original position around the support rod 10.

[0022] Working principle: The operator can control the tension of the pull rope 5 to drive the drive shaft 4 and drive slider 3 to slide inside the drive slide rail 2, thereby driving the first drive shaft 8 and the second drive shaft 9 on the left to rotate. Through the operation of the drive arm 13 and the back-and-forth swing of the drive frame 14 around the third drive shaft 15, the fixed clamping plate 18 is moved. Then, by controlling the clamping degree of the fixed clamping plate 18 on the cable, it can ensure a firm fixation while avoiding excessive compression that could cause cable deformation or insulation damage. It can provide a large clamping stroke, making it able to adapt to cables of different diameters within a certain range. When it is moved to the appropriate position, the drive shaft 4 is fixed by rotating the fixing bolt 6 to ensure the stability of the cable clamping. Qualitatively, the end of the cable is clamped inside the first rubber gear 17 and the second rubber gear 19. The cable on the rear side passes through the middle side of the auxiliary rod 20, wraps around the side of the movable rod 11, and then passes through the side of the rear auxiliary rod 20, forming an arc shape, making the path of each cable clearly visible. This greatly facilitates daily inspection, fault diagnosis, and line tracing for complex instrument circuits. It can effectively prevent multiple cables from crossing and tangling, making the layout neater and more standardized. When the cable is pulled to apply external force, the movable rod 11 slides to the left under the action of external force, so that the cable is on a horizontal line, which is convenient for the operator to carry out subsequent operations. When the external force is removed, the spring 12 drives the movable rod 11 to return to its original position around the support rod 10.
