Description

Technical Field

[0001] This invention relates to the field of clamping, and more specifically to a cable clamping device. Background Technology

[0002] The frequency conversion energy-saving control device for condensate pumps in thermal power plants, also known as the condensate pump automatic controller, is usually integrated into a field control box. It forms a local control system that integrates data acquisition, logic operation, and frequency conversion drive. Its core is to monitor parameters such as hot well water level and medium temperature in real time through the built-in intelligent control unit, and automatically adjust the pump speed to achieve on-demand flow supply, thereby significantly reducing energy consumption. During installation, the controller is fixed to the back plate of the control box through mounting holes and screws. At the same time, there are wiring terminals at the bottom of the controller for connecting control cables.

[0003] However, during use, when the automatic controller for condensate pumps is being inspected, replaced, or routinely maintained on-site, maintenance personnel may unintentionally touch or snag the connected cables with their hands, tools, or sleeves. If the contact force is too strong, the cables may come loose instantly or the connection between the plug and the cable may break, causing the equipment to suddenly lose power and communication to be interrupted, leading to unplanned shutdowns and production accidents. Summary of the Invention

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference Figures 1-10 As shown, the cable clamping device of this embodiment includes a fixed frame 1, a first clamping component 2, a second clamping component 3, and a positioning component 4. The fixed frame 1 is connected to a controller 13 and has a cable through hole 101 for the cable on the controller 13 to pass through. The first clamping component 2 and the second clamping component 3 are disposed on the fixed frame 1, and at least one of the first clamping component 2 and the second clamping component 3 is movably connected to the fixed frame 1. The first clamping component 2 and the second clamping component 3 cooperate to clamp the cable connected to the controller 13. The positioning component 4 is disposed between the first clamping component 2 and the second clamping component 3 and is movable relative to the first clamping component 2 and the second clamping component 3, for locking and releasing the first clamping component 2 and the second clamping component 3 when the cable is clamped.

[0032] In use, the cable clamping device of this embodiment connects the fixed frame 1 to the controller 13. The fixed frame 1 has a cable passage hole 101 for cable passage, ensuring the cable is inserted into the controller 13. A first clamping component 2 and a second clamping component 3 are mounted on the fixed frame 1, with at least one component movably connected to the fixed frame 1 for easy cable clamping. When cable clamping is required, the first clamping component 2 and the second clamping component 3 cooperate to clamp the cable, ensuring it will not loosen due to external force. A positioning component 4 is located between the first clamping component 2 and the second clamping component 3, used to lock and release the clamping components when clamping the cable. Thus, during maintenance or repair, the cable can be locked or released using the positioning component 4.

[0033] Compared with related technologies, the clamping device can prevent maintenance personnel's hands, tools or sleeves from accidentally touching or snagging on the cable, reducing the risk of cable loosening or connection breakage due to improper operation. When it is necessary to replace the module or perform routine maintenance, the positioning component 4 can easily lock and release the cable, which is convenient and reduces maintenance time and labor intensity.

[0034] In some embodiments, such as Figures 1-4As shown, the positioning component 4 of the cable clamping device in this embodiment of the invention includes a connecting plate 401, a first locking pin 402, a second locking pin 403, and an elastic member 404. The connecting plate 401 is disposed between the first clamping component 2 and the second clamping component 3 and is movable relative to the first clamping component 2 and the second clamping component 3. The first locking pin 402 and the second locking pin 403 are disposed on the connecting plate 401. The first clamping component 2 has a first locking groove 201, and the second clamping component 3 has a second locking groove 301. The first locking pin 402 can be engaged in the first locking groove 201, and the second locking pin 403 can be engaged in the second locking groove 301 to lock the first clamping component 2 and the second clamping component 3. The elastic member 404 is disposed in the second locking groove 301 and connected between the bottom wall surface of the second locking groove 301 and the second locking pin 403.

[0035] When it is necessary to lock the first clamping component 2 and the second clamping component 3, the first locking pin 402 and the second locking pin 403 are respectively inserted into the first locking groove 201 and the second locking groove 301 by moving the connecting plate 401. The function of the elastic member 404 is to ensure that the second locking pin 403 is locked in the second locking groove 301 and to prevent the second locking pin 403 from falling out of the second locking groove 301.

[0036] Due to the movement of the connecting plate 401 and the insertion of the locking pin, the operator can lock and release the clamping component. The use of the elastic element 404 ensures that the clamping component prevents the second locking pin 403 from falling out of the second locking slot 301 after locking.

[0037] In some embodiments, such as Figure 4 As shown, the end face of the first clamping post 402 of the cable clamping device in this embodiment of the invention, away from the connecting plate 401, has a guide slope 4021. The guide slope 4021 is used to guide the first clamping post 402 to engage in the first clamping slot 201 when the positioning component 4 locks and positions the first clamping component 2 and the second clamping component 3. The guide slope 4021 allows the first clamping component 2 to move along the guide slope 4021 when the first clamping component 2 and the second clamping component 3 approach each other, thereby pushing the first clamping post 402 downward, allowing the first clamping post 402 to slide along the bottom of the first clamping component 2, and finally inserting the first clamping post 402 into the position of the first clamping slot 201.

[0038] In some embodiments, such as Figures 2-4As shown, the cable clamping device of this embodiment of the invention further includes a first rotating member 5 and a second rotating member 6. The first rotating member 5 and the second rotating member 6 are both disposed on the fixed frame 1 and are rotatable relative to the fixed frame 1. The first clamping member 2 is rotatably disposed on the fixed frame 1 through the first rotating member 5, and the second clamping member 3 is rotatably disposed on the fixed frame 1 through the second rotating member 6. The first rotating member 5 and the second rotating member 6 cooperate so that when one of the first clamping member 2 and the second clamping member 3 rotates, it can drive the other to rotate.

[0039] When the first clamping component 2 is rotated, the cooperation of the first rotating component 5 and the second rotating component 6 will drive the second clamping component 3 to rotate synchronously. Rotating the second clamping component 3 will also drive the first clamping component 2 to rotate synchronously. This linkage design ensures that the two clamping components can open and close synchronously and symmetrically. The entire clamping device can be opened and closed by operating either clamping component. When it is necessary to install or remove cables, rotating one clamping component will cause the other to rotate synchronously, thus simultaneously releasing or clamping the cable. The cable is clamped between the two clamping components, forming a stable and fixed state. The entire clamping device can be opened and closed by operating either clamping component. When it is necessary to install or remove cables, rotating one clamping component will cause the other to rotate synchronously, thus simultaneously releasing or clamping the cable.

[0040] The clamping device can be opened and closed with one hand, simplifying the maintenance process. It eliminates the need to operate the two clamping components separately, reducing operational complexity and making it particularly suitable for space-constrained maintenance environments, thus improving work efficiency. The linked design ensures that the two clamping components apply uniform clamping force to the cable, avoiding uneven clamping force that may occur with manual operation, improving the reliability of cable fixation, and effectively preventing accidental cable loosening.

[0041] In some embodiments, such as Figures 2-4 As shown, in this embodiment of the cable clamping device, the first rotating member 5 is a first gear 501, which is mounted on the fixed frame 1 and rotatable relative to the fixed frame 1. The first clamping member 2 is rotatably mounted on the fixed frame 1 via the first gear 501. The second rotating member 6 is a second gear 601, which is mounted on the fixed frame 1 and rotatable relative to the fixed frame 1. The second clamping member 3 is rotatably mounted on the fixed frame 1 via the second gear 601. The second gear 601 and the first gear 501 mesh with each other so that when one of the first clamping member 2 and the second clamping member 3 rotates, it can drive the other to rotate.

[0042] The first rotating component 5 is in the form of a first gear 501, which is fixedly installed on the fixed frame 1 and can rotate freely. The second rotating component 6 is in the form of a second gear 601, which is also fixedly installed on the fixed frame 1 and can rotate freely. The first gear 501 and the second gear 601 mesh with each other to form a gear transmission pair.

[0043] The first clamping component 2 is fixedly connected to or integrally formed with the first gear 501 and rotates synchronously with the first gear 501. The second clamping component 3 is fixedly connected to or integrally formed with the second gear 601 and rotates synchronously with the second gear 601. Since the two gears mesh with each other, when one gear rotates, it drives the other gear to rotate in the opposite direction through gear meshing.

[0044] When maintenance personnel operate the first clamping component 2 to rotate it, the first gear 501 rotates accordingly. The first gear 501, through meshing, drives the second gear 601 to rotate in the opposite direction. The second gear 601 then drives the second clamping component 3 to rotate synchronously in the opposite direction. Conversely, operating the second clamping component 3 will produce the same linkage effect. This rotational design allows the two clamping components to open and close symmetrically, achieving stable clamping or release of the cable.

[0045] The gear-driven cable clamping device achieves synchronous and symmetrical movement of two clamping components through gear transmission, which not only improves the stability and reliability of clamping, but also enhances the load-bearing capacity and service life of the device. It is suitable for applications in industrial environments such as thermal power plants where equipment reliability requirements are high.

[0046] In some embodiments, such as Figure 3 As shown, the first clamping component 2 of the cable clamping device in this embodiment of the invention includes a first rotating frame 202, a first sliding frame 203, a first plate 204 and a first clamping plate 205. The first rotating frame 202 is disposed on the fixed frame 1 and is rotatable relative to the fixed frame 1. The first sliding frame 203 passes through the first rotating frame 202 and is movable relative to the fixed frame 1. The first plate 204 is disposed on the first sliding frame 203. The first clamping plate 205 is disposed on the first sliding frame 203 and is movable relative to the first sliding frame 203.

[0047] The first rotating frame 202 serves as the basic structure and is rotatably connected to the fixed frame 1 via the first gear 501. The first sliding frame 203 passes through the interior of the first rotating frame 202, forming a sliding fit relationship, and can move relative to the fixed frame 1 in the vertical direction. The first plate 204 is fixedly installed on the first sliding frame 203 and moves together with the first sliding frame 203. The first clamping plate 205 is installed on the first sliding frame 203 but has a relative sliding function and can move horizontally relative to the first sliding frame 203.

[0048] When the first rotating frame 202 rotates, it can drive the first sliding frame 203 to perform a compound motion (both horizontal rotation and vertical linear movement). The first plate 204 moves synchronously with the first sliding frame 203 to provide structural support. The first clamping plate 205 can slide relative to the first sliding frame 203 to form an adaptive adjustment capability.

[0049] Rotating the first rotating frame 202 causes the second clamping component 3 to rotate synchronously via gear linkage. The first sliding frame 203 moves with the first rotating frame 202 and simultaneously generates a linear displacement in the up and down direction. Under the action of the spring or elastic element 404, the first clamping plate 205 can slide relative to the first sliding frame 203, automatically adjusting the clamping position and force.

[0050] In some embodiments, such as Figure 3 As shown, the second clamping component 3 of the cable clamping device in this embodiment of the invention includes a second rotating frame 303, a second sliding frame 303, a second plate 304, and a second clamping plate 305. The second rotating frame 303 is disposed on the fixed frame 1 and is rotatable relative to the fixed frame 1. The second sliding frame 303 passes through the second rotating frame 303 and is movable relative to the fixed frame 1. The second plate 304 is disposed on the second sliding frame 303. The second clamping plate 305 is disposed on the second sliding frame 303 and is movable relative to the second sliding frame 303. The second clamping plate cooperates with the first clamping plate 205 to clamp the cable connected to the controller 13. The second sliding frame 303 and the first sliding frame 203 cooperate to drive the cable clamped by the second clamping plate 305 and the first clamping plate 205 to move.

[0051] The second clamping component 3 adopts the same structural design as the first clamping component 2, including a second rotating frame 303, a second sliding frame 303, a second plate 304 and a second clamping plate 305. The second rotating frame 303 is rotatably connected to the fixed frame 1 through the second gear 601 and meshes with the first gear 501 to form a transmission relationship.

[0052] The second sliding frame 303 is inserted inside the second rotating frame 303 to form a sliding fit relationship, and can move relative to the fixed frame 1.

[0053] When the first rotating frame 202 rotates, it drives the second rotating frame 303 to rotate synchronously in the opposite direction through gear linkage. The first sliding frame 203 and the second sliding frame 303 can produce a compound motion (horizontal rotation and vertical linear movement) under the drive of their respective rotating frames. The first clamping plate 205 and the second clamping plate 305 form a symmetrical clamping structure to clamp the cable from both sides. The second sliding frame 303 and the first sliding frame 203 have a mechanical cooperation relationship, which can drive the clamped cable to move in the up and down direction.

[0054] The symmetrical design of the first clamping plate 205 and the second clamping plate 305 clamps the cable evenly from both sides, providing a more stable fixation. Two-point clamping is more reliable than single-point clamping, effectively preventing cable twisting and displacement. The combination of gear linkage and sliding structure allows for single-handed operation to complete clamping and cable adjustment. Maintenance personnel only need to rotate any one of the rotating frames to achieve synchronous operation of the entire clamping system.

[0055] In some embodiments, such as Figure 6 and Figure 7 As shown, the cable clamping device of this embodiment has a first chamber in the fixed frame 1 and a first groove 103 on the outer side wall of the fixed frame 1. The first groove 103, the first chamber and the first clamping component 2 correspond one-to-one. The first groove 103 communicates with the first chamber. The inner side wall of the first chamber has a second groove. The cable clamping device also includes a first transmission component. The first transmission component is disposed in the first sliding frame 203. At least part of the first transmission component passes through the first groove 103 and can be placed in the second groove and slide in cooperation with the second groove, so that when the first rotating frame 202 rotates relative to the fixed frame 1, the first transmission component can drive the sliding frame to move relative to the fixed frame 1.

[0056] When the first rotating frame 202 rotates relative to the fixed frame 1, the rotational motion is converted into linear motion through the mechanical linkage of the first transmission component, driving the first sliding frame 203 to move relative to the fixed frame 1. By cleverly integrating the transmission component into the first chamber inside the fixed frame 1, a compact structure is achieved, reducing the external space occupied. The first slide groove 103 and the second slide groove provide dual guidance, improving the accuracy of the movement of the first sliding frame 203 and avoiding skewing and jamming during the movement.

[0057] Direct mechanical transmission reduces intermediate steps and has high efficiency in converting rotational motion to linear motion.

[0058] In some embodiments, the cable clamping device of the present invention further includes a second chamber 105 in the fixed frame 1, and a third slide groove 106 on the outer side wall of the fixed frame 1. The third slide groove 106, the second chamber 105 and the second clamping component 3 correspond one-to-one. The third slide groove 106 communicates with the second chamber 105. The inner side wall of the second chamber 105 has a fourth slide groove 107. The cable clamping device also includes a second transmission component 8. The second transmission component 8 is disposed in the second sliding frame. At least a portion of the second transmission component 8 passes through the third slide groove 106 and can be placed in the fourth slide groove 107 and slide in cooperation with the fourth slide groove 107, so that when the second rotating frame 303 rotates relative to the fixed frame 1, the second transmission component 8 can drive the second sliding frame 303 to move relative to the fixed frame 1.

[0059] A second chamber 105 is added inside the fixed frame 1, forming a parallel or symmetrical layout with the first chamber. A third slide groove 106 is provided on the outer side wall of the fixed frame 1, forming a symmetrical or complementary relationship with the first slide groove 103. A fourth slide groove 107 is provided on the inner side wall of the second chamber 105, forming a symmetrical structure with the second slide groove.

[0060] When the second rotating frame 303 rotates relative to the fixed frame 1, the rotational motion is converted into linear motion through the mechanical linkage of the second transmission component 8, which drives the second sliding frame 303 to move in the up and down direction relative to the fixed frame 1.

[0061] The first transmission assembly and the second transmission assembly 8 form a dual-drive system. These two systems can work independently or collaboratively, enabling control of the first clamping component 2 and the second clamping component 3. The dual transmission systems form a symmetrical structure, resulting in more even force distribution. The two transmission systems ensure synchronous movement of the first clamping component 2 and the second clamping component 3, achieving uniform clamping of the cable.

[0062] In some embodiments, such as Figure 6 and Figure 7 As shown, the first transmission component of the cable clamping device in this embodiment of the invention includes a first rod body. The first rod body is disposed in the first sliding frame 203 and is movable relative to the fixed frame 1. The first rod body has a first protrusion. The first protrusion passes through the first sliding groove 103 to be placed in the first cavity. At least a portion of the first protrusion is placed in the second sliding groove and slides in cooperation with the second sliding groove, so that when the first rotating frame 202 rotates relative to the fixed frame 1, the first rod body drives the first sliding frame 203 to move relative to the fixed frame 1. The second transmission component 8 includes a second rod body 802. The second rod body 802 is disposed in the second sliding frame 303 and is movable relative to the fixed frame 1. The second rod body 802 has a second protrusion 8021. The second protrusion 8021 passes through the third sliding groove 106 to be placed in the second cavity 105. At least a portion of the second protrusion 8021 is placed in the fourth sliding groove 107 and slides in cooperation with the fourth sliding groove 107, so that when the second rotating frame 303 rotates relative to the fixed frame 1, the second rod body 802 drives the second sliding frame 303 to move relative to the fixed frame 1.

[0063] The first rod is mounted on the first sliding frame 203 and can move relative to the fixed frame 1. The first rod has a first protrusion as a transmission point. The first protrusion passes through the first sliding groove 103 and enters the first chamber. A part of the first protrusion is embedded in the second sliding groove to form a sliding fit.

[0064] When the first rotating frame 202 rotates relative to the fixed frame 1, it drives the first rod to move through a mechanical connection. The first protrusion slides in the second slide groove, converting the rotational motion into linear motion. The first rod drives the first sliding frame 203 to move relative to the fixed frame 1. The second rod 802 is mounted on the second sliding frame 303 and can move relative to the fixed frame 1. The second rod 802 is provided with a second protrusion 8021 as a transmission point. The second protrusion 8021 passes through the third slide groove 106 and enters the second chamber 105. A part of the second protrusion 8021 is embedded in the fourth slide groove 107 to form a sliding fit.

[0065] When the second rotating frame 303 rotates relative to the fixed frame 1, it drives the second rod 802 to move through the mechanical connection. The second protrusion 8021 slides in the fourth slide groove 107, converting the rotational motion into linear motion. The second rod 802 drives the second sliding frame 303 to move relative to the fixed frame 1.

[0066] By directly driving the first and second rods 802, intermediate transmission links are reduced, resulting in a simple and compact structure that lowers manufacturing costs.

[0067] Optionally, before the first clamping component 2 and the second clamping component are combined, the first clamping plate 205 and the second clamping plate 305 can be tightly pressed against the surface of the cable. That is, when the first clamping component 2 and the second clamping component 3 move upward, the first clamping plate 205 and the second clamping plate 305 clamp the cable, and the clamping position of the cable is upward, thereby causing the cable to bend automatically, thus allowing for a buffer distance.

[0068] The first slide groove 103 and the third slide groove 106 are arc-shaped grooves, and the arc-shaped grooves are symmetrically arranged. The arc-shaped grooves and the gears adjacent to them are kept at the same center position. The second slide groove and the fourth slide groove 107 are composed of inclined grooves and transverse grooves.

[0069] When the first rotating frame 202 and the second rotating frame 303 rotate, they rotate around the center of the corresponding gear. As the first rotating frame 202 and the second rotating frame 303 rotate, the first sliding frame 203 and the second sliding frame 303 also rotate, causing the first rod at the top of the first sliding frame 203 to slide inside the first sliding groove 103. When the first rod slides, the first protrusion on its surface slides inside the second sliding groove, allowing the first rod to move up and down. In other words, the first rod drives the first sliding frame 202... The upward and downward sliding of the second sliding frame 303 allows the cable clamping position to automatically move upward, thereby causing the second rod 802 at the top of the second sliding frame 303 to slide inside the third sliding groove 106. When the second rod 802 slides, the second protrusion 8021 on its surface will slide inside the fourth sliding groove 107, thereby enabling the second rod 802 to move up and down. In other words, by driving the second sliding frame 303 to slide up and down through the second rod 802, the first sliding frame 203 and the second sliding frame 303 can automatically move the cable clamping position upward, reserving a buffer position.

[0070] In use, when the first clamping component 2 and the second clamping component 3 open, the first rotating frame 202 will rotate, causing the first rod to slide inside the first slide groove 103. The first protrusion will slide from the top of the inclined groove of the second slide groove to the bottom of the inclined groove, and then slide inside the horizontal groove. That is to say, when the first clamping component 2 and the second clamping component 3 open, the first sliding frame 203 will first descend. After descending to the limit position, the first sliding frame 203 will continue to rotate and will not descend further.

[0071] When the first clamping component 2 and the second clamping component 3 open, the second rotating frame 303 will rotate, causing the second rod 802 to slide inside the third slide groove 106. The second protrusion 8021 will slide from the top of the inclined groove of the fourth slide groove 107 to the bottom of the inclined groove, and then slide inside the horizontal groove. That is to say, when the first clamping component 2 and the second clamping component 3 open, the second sliding frame 303 will first descend. After descending to the limit position, the second sliding frame 303 will continue to rotate and will not descend further.

[0072] In some embodiments, such as Figures 8-10 As shown, the cable clamping device of this embodiment of the invention further includes a first buffer component 9 and a second buffer component 10. The first buffer component 9 is disposed between the first plate 204 and the first clamping plate 205, and the second buffer component 10 is disposed between the second plate 304 and the second clamping plate 305. The second buffer component 10 and the first buffer component 9 cooperate to buffer the cable when the cable connected to the controller 13 is clamped by the second clamping plate 305 and the first clamping plate 205.

[0073] The cable clamping device also includes a first fastening component 11 and a second fastening component 12. The first fastening component 11 is disposed between the first plate 204 and the first clamping plate 205 and is rotatable relative to the first plate 204. The movement of the first clamping plate 205 can drive the first fastening component 11 to rotate. The second fastening component 12 is disposed between the second plate 304 and the second clamping plate 305 and is rotatable relative to the second plate 304. The movement of the second clamping plate 305 can drive the second fastening component to rotate. The second fastening component 12 cooperates with the first fastening component 12 to clamp the cable connected to the controller 13.

[0074] The first buffer assembly 9 is installed between the first plate 204 and the first clamping plate 205, and the second buffer assembly 10 is installed between the second plate 304 and the second clamping plate 305. The two sets of buffer assemblies form a symmetrical structure and are located on both sides of the cable respectively.

[0075] When the second clamping plate 305 and the first clamping plate 205 clamp the cable, the cable is subjected to external impact. The buffer component absorbs the impact energy through elastic deformation, reduces the stress on the cable, and prevents cable damage or loosening of connection points. The buffer component can automatically adjust the buffering force according to the magnitude of the external force, providing stable support during normal operation and providing additional buffer protection when subjected to impact.

[0076] The first fastening component 11 is installed between the first plate 204 and the first clamping plate 205 and can rotate relative to the first plate 204. The second fastening component 12 is installed between the second plate 304 and the second clamping plate 305 and can rotate relative to the second plate 304. The two sets of fastening components form a cooperative working relationship.

[0077] When the first clamping plate 205 moves, it drives the first fastening component 11 to rotate. When the second clamping plate 305 moves, it drives the second fastening component 12 to rotate. The two sets of fastening components work together to form a clamping force, which acts on the cable. When the clamping plates move, the fastening components rotate accordingly. The rotation of the fastening components generates a clamping force. The two sets of fastening components work together to clamp the cable from both sides, forming multi-point contact and enhancing clamping stability.

[0078] The first buffer component 9 and the second buffer component 10 can effectively absorb impact energy, prevent the cable from being mechanically damaged, reduce stress concentration at cable connection points, extend cable service life, and reduce replacement frequency. They can automatically adjust the buffer force according to the magnitude of external force, providing optimal protection under different working conditions, improving the adaptability and reliability of the device. The dual buffer component design ensures that the cable is subjected to uniform force on both sides, avoiding cable deformation or damage caused by unilateral force, and improving the stability and reliability of clamping.

[0079] The buffer assembly and fastening components form a dual protection. The buffer assembly absorbs the impact, while the first fastening component 11 and the second fastening component 12 provide stable clamping, which greatly improves the reliability of the cable connection.

[0080] In some embodiments, such as Figures 8-10 As shown, the first buffer assembly 9 of the cable clamping device in this embodiment of the invention includes a first sliding post 901, a first baffle 902 and a first reset component 903. The first sliding post 901 passes through the first plate 204 and is connected to the first clamping plate 205. The first baffle 902 is disposed at the end of the first sliding post 901 away from the first clamping plate 205. The first reset component 903 is disposed on the first baffle 902 and surrounds the first sliding post 901.

[0081] The second buffer assembly 10 includes a second sliding post 1001, a second baffle 1002, and a second reset component 1003. The second sliding post 1001 passes through the second plate 304 and is connected to the second clamping plate 305. The second baffle 1002 is located at the end of the second sliding post 1001 away from the second clamping plate 305. The second reset component 1003 is located at the second baffle 1002 and surrounds the second sliding post 1001. The first fastening component 11 includes a first rotating frame 1101, a first push rod 1102, and a first spring-loaded component 1103. The first rotating frame 1101 is located at one end of the first plate 204 away from the first clamping plate 205 and is rotatable relative to the first plate 204. The first push rod 1102 passes through the first plate 204 and is connected to the first clamping plate 205. The end of the first push rod 1102 away from the first clamping plate 205 can directly reach the first rotating frame 1101. The first spring-loaded component 1103 is located between the first rotating frame 1101 and the first plate 204. The movement of the first clamping plate 205 can drive the first push rod 1102 to move, and the first push rod 1102 can push the first rotating frame 1101 to rotate.

[0082] The second fastening component 12 includes a second rotating frame 1201, a second push rod 1202, and a second spring-loaded component 1203. The second rotating frame 1201 is located on the two ends of the second plate 304 away from the second clamping plate 305 and is rotatable relative to the second plate 304. The second push rod 1202 passes through the second plate 304 and is connected to the second clamping plate 305. The two ends of the second push rod 1202 away from the second clamping plate 305 can directly reach the second rotating frame 1201. The second spring-loaded component 1203 is located between the second rotating frame 1201 and the second plate 304. The second clamping plate 305 can drive the second push rod 1202 to move. The movement of the second push rod 1202 can push the second rotating frame 1201 to rotate. The second rotating frame 1201 cooperates with the first rotating frame 1101 to clamp the cable connected to the controller 13.

[0083] The first sliding post 901 passes through the first plate 204 and is fixedly connected to the first clamping plate 205. The first baffle 902 is installed at the end of the first sliding post 901 away from the first clamping plate 205. The first reset component 903 (spring) is arranged around the first sliding post 901 and connected between the first baffle 902 and the first plate 204.

[0084] When the first clamping plate 205 is subjected to external impact or vibration, the first sliding column 901 drives the first baffle 902 to move, the first reset component 903 is compressed to absorb the impact energy, and after the impact, the first reset component 903 returns to its original state to provide rebound force and achieve buffer protection for the cable.

[0085] The second sliding post 1001 passes through the second plate 304 and is fixedly connected to the second clamping plate 305. The second baffle 1002 is installed at the end of the second sliding post 1001 away from the second clamping plate 305. The second reset component 1003 is arranged around the second sliding post 1001 and is connected between the second baffle 1002 and the second plate 304.

[0086] Similar to the first buffer assembly 9, it provides buffer protection for the cable from the other side, working in conjunction with the first buffer assembly 9 to form a double-sided buffer.

[0087] The first rotating frame 1101 is installed on the end of the first plate 204 away from the first clamping plate 205 and can rotate relative to the first plate 204. The first push rod 1102 passes through the first plate 204, with one end connected to the first clamping plate 205 and the other end contacting the first rotating frame 1101. The first return element 1103 (torsion spring) is disposed between the first rotating frame 1101 and the first plate 204.

[0088] When the first clamping plate 205 moves, the first push rod 1102 drives the first rotating frame 1101 to rotate. The rotating first rotating frame 1101 and the second rotating frame 1201 cooperate to form a clamping force, and the first spring-loaded component 1103 provides a restoring force to ensure that the fastening component returns to the initial position.

[0089] The second rotating frame 1201 is installed on one end of the second plate 304 away from the second clamping plate 305 and can rotate relative to the second plate 304. The second push rod 1202 passes through the second plate 304, with one end connected to the second clamping plate 305 and the other end contacting the second rotating frame 1201. The second spring element 1203 is disposed between the second rotating frame 1201 and the second plate 304.

[0090] The second fastening component 12 works on the same principle as the first fastening component 11, and works in conjunction with the first fastening component 11 to clamp the cable from both sides to form a stable cable fixing structure.

[0091] The design of the sliding post and reset component provides an efficient buffering mechanism that effectively absorbs and disperses impact energy, reduces stress on the cable, and prevents cable damage. The first buffer assembly 9 and the second buffer assembly 10 form double-sided protection, absorbing impact and vibration from two directions and providing all-around cable protection.

[0092] The movement of the clamping plate automatically drives the fastening components, simplifying the operation process, improving the degree of automation, reducing the need for manual intervention, and stabilizing the clamping force.

[0093] The lever design of the rotating frame and push rod provides stable clamping force, and the spring mechanism ensures continuous clamping effect, effectively preventing the cable from coming loose during use.

[0094] The rotating frame design can accommodate cables of different diameters and provides the ability to automatically adjust the clamping force, enhancing the versatility and adaptability of the device.

[0095] The spring mechanism provides a reliable reset function, ensuring that the fasteners return to their initial position after each use, thus improving long-term reliability.

[0096] The first buffer component 9 and the second buffer component 10 absorb the impact, while the first fastening component 11 and the second fastening component 12 provide stable clamping. The two mechanisms work together to form all-round protection, which greatly improves the reliability of the cable connection.
