Description

Technical Field

[0001] This invention relates to the field of cable fixing technology, and more specifically, to a cable fixing mechanism for mechanical equipment. Background Technology

[0002] In the practical application scenarios of modern mechanical equipment, cables, as the key carriers of power transmission and signal transmission, are directly related to the safe and stable operation of the entire equipment system due to the reliability of their fixing methods. Looking at the cable fixing technologies commonly used in the market, a large number of mechanical equipment still use traditional and simple fixing methods, such as ordinary plastic cable ties, simple metal clips, or basic cable tray wiring. Although these traditional methods are simple and quick to operate in the initial installation, require low material costs, and can be operated by construction personnel without professional training, their inherent technical defects gradually become apparent after the equipment has been used for a long time. Due to the generally insufficient mechanical strength of these simple fixing structures and the lack of effective buffering and protection design, cables are prone to problems such as loosening of fixing points, displacement of cable position, or even falling off when subjected to multiple external forces such as continuous vibration generated during equipment operation, sudden tensile force, and temperature fluctuations in the working environment.

[0003] Especially in heavy industrial production lines, large-scale machining equipment, or automated devices that require frequent movement, this unstable and simple fixing method exposes more hidden dangers. Plastic cable ties will become brittle and break due to aging after long-term use, metal clips are prone to fatigue and loosening under repeated vibration, and adhesive fixing brackets will fall off due to adhesive failure. None of these can provide a lasting and reliable fixing effect for cables. Once the cable is not securely fixed, it will shake and rub during equipment operation, leading to a series of chain failures such as accelerated wear of the surface insulation layer, stress concentration at bends, gradual breakage of the internal copper core, and loosening of joints. This not only greatly shortens the service life of the cable and increases the frequency and cost of replacement and maintenance, but in more serious cases, it may also cause major safety accidents such as electrical short circuits, signal interruptions, sudden equipment shutdowns, or even fires caused by cable damage, resulting in economic losses and safety hazards for enterprises. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a cable fixing mechanism for mechanical equipment to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cable fixing mechanism for mechanical equipment includes a cable and a locking mechanism. The locking mechanism includes a retaining tube, the cable being slidably connected to the inner wall of the retaining tube, the inner wall of the retaining tube having multiple sets of inclined grooves, one end of the retaining tube being connected to an installation ring, the outer wall of the retaining tube being fitted with a hexagonal ring, the side wall of the hexagonal ring being connected to a reinforcing sleeve, the reinforcing sleeve being threadedly connected to the outer wall of the retaining tube, the outer wall of the retaining tube being slidably connected to a push ring, and a thrust bearing being provided between the reinforcing sleeve and the push ring.

[0007] Preferably, the inner wall of the push ring is provided with multiple sets of sliders, and the outer wall of the retaining tube is provided with multiple sets of sliding grooves adapted to the sliders. The sliders are embedded in the sliding grooves and slidably connected with the sliding grooves. This arrangement ensures that the push ring can only slide along the axial direction of the retaining tube without rotating, thus ensuring accurate force transmission and stability of the pushing action.

[0008] Preferably, the outer wall of the locking tube is threaded with a threaded sleeve, and the inner wall of the threaded sleeve is provided with a locking strip. This configuration realizes position adjustment through threaded transmission, allowing the operator to easily control the horizontal movement distance of the locking block.

[0009] Preferably, a slip ring is slidably connected to the outer wall of the card tube, and a groove adapted to the card strip is formed on the outer wall of the slip ring. The card strip is embedded in the groove and rotatably connected to the groove. Multiple sets of slots are formed on the side wall of the slip ring. This configuration ensures that the slip ring only moves linearly and does not rotate with the threaded sleeve when it rotates, thus ensuring the simplicity and controllability of the adjustment action.

[0010] Preferably, multiple sets of first and second sliders are slidably connected within the inclined groove. The first and second sliders are fixedly connected. This arrangement achieves a ring-shaped enclosure fixation of the cable through the synergistic effect of multiple sets of sliders, improving the uniform distribution of clamping force and the overall fixation effect.

[0011] Preferably, the inner wall of the first slider is provided with a first locking groove, and the inner wall of the second slider is provided with a second locking groove. Both the first locking groove and the second locking groove are inclined. This inclined arrangement converts the horizontal movement of the slider into the vertical tightening force of the locking block, thereby realizing the gradual wrapping and clamping of the cable surface.

[0012] Preferably, a first locking block is slidably connected in the first locking groove, and a second locking block is slidably connected in the second locking groove. The first locking block and the second locking block are fixedly connected, and the sidewalls of the first locking block and the second locking block are tightly abutting against the outer sidewall of the cable. This arrangement ensures that the locking blocks can closely fit the cable surface, providing reliable friction and clamping force to prevent the cable from slipping.

[0013] Preferably, the outer wall of the first locking block is provided with an arc-shaped tube, and one end of the arc-shaped tube is provided with an insert plate. The insert plate is provided with multiple sets of elastic plates. The insert plate is inserted into the slot and slidably connected to the slot. This arrangement reduces the resistance during the insertion process through the buffering effect of the elastic plates, so that the insert plate can smoothly slide in the slot to complete the position adjustment.

[0014] Preferably, the outer wall of the first slider is provided with an adjustment groove, the insert plate is slidably connected to the adjustment groove, the first slider is provided with a retaining plate, the retaining plate is slidably connected to the inclined groove, and the push ring abuts against the side walls of multiple sets of retaining plates. This arrangement allows the insert plate to slide laterally in the adjustment groove to adapt to position adjustment, and at the same time, the push ring pushes the retaining plate to realize the drive control of the entire slider assembly.

[0015] Preferably, the bottom of the card plate is provided with a push spring, which is located inside the arc-shaped tube and slidably connected to the arc-shaped tube. The other end of the push spring is fixedly connected to the bottom side wall of the insertion plate. This arrangement ensures that the card plate always maintains a tight contact with the push ring through the elastic restoring force of the push spring.

[0016] Compared with existing technologies, this invention provides a cable fixing mechanism for mechanical equipment, which has the following advantages: By setting a locking mechanism, this invention changes the problem of cumbersome operation of traditional cable fixing methods. Operators only need to simply rotate the threaded sleeve and the reinforcing sleeve to complete the entire process of fixing and disassembling the cable. There is no need to use complicated special tools or disassemble a large number of parts. The entire operation process is intuitive and clear, and even ordinary operators can quickly get started. This shortens the time required for installation and maintenance and improves work efficiency. Especially in application scenarios where cables need to be frequently replaced or repaired, such as daily maintenance of production lines, equipment upgrades and renovations, and troubleshooting, this convenience advantage is even more prominent. It can effectively reduce equipment downtime, reduce production interruptions caused by maintenance operations, and significantly reduce labor costs and improve overall production efficiency.

[0017] This invention employs multiple locking mechanisms. Multiple sets of inclined grooves on the inner wall of the clamping tube, in conjunction with the first and second sliders, achieve radial tightening. Guided by the inclined grooves, the sliders move synchronously towards the center along a conical trajectory, forming a uniformly distributed annular clamping force. Simultaneously, the inclined design of the first and second locking grooves ensures that the first and second locking blocks remain stable horizontally during slider movement and also generate a progressive tightening action vertically, forming a wrapping multi-point clamping effect on the cable surface. This ensures sufficient fixing strength while avoiding damage to the cable insulation layer. This mechanism effectively resists various complex external forces generated during equipment operation, such as continuous vibration, sudden pulling, lateral impact, and thermal expansion and contraction caused by temperature changes. It ensures the cable position remains stable, effectively extending the cable's service life and reducing the risk of cable wear, breakage, and loose joints due to insecure fixing. It also reduces the probability of sudden equipment shutdowns and safety accidents.

[0018] This invention incorporates a position adjustment function. The rotation of the threaded sleeve drives the locking block to move horizontally, adjusting its position relative to the cable surface. This allows the fixing mechanism to select the appropriate clamping point based on the actual condition of the cable surface. This adjustability enables the locking mechanism to accommodate cables of various diameters, from thinnest to thickest. One device can meet multiple application needs, improving the product's versatility and applicability. It also reduces the number of fixing device models that companies need to purchase and stock, lowering inventory costs and management complexity. Furthermore, the push spring plays a crucial role throughout the adjustment and use process. Its continuous elastic restoring force ensures that the clamping plate remains in close contact with the push ring sidewall, maintaining a tight fit between all transmission components and ensuring the long-term stability and service life of the fixing mechanism.

[0032] Please see Figures 1-9A cable fixing mechanism for mechanical equipment includes a cable 11 and a locking mechanism. The locking mechanism includes a retaining tube 21, the cable 11 being slidably connected to the inner wall of the retaining tube 21. Multiple sets of inclined grooves 22 are formed on the inner wall of the retaining tube 21. One end of the retaining tube 21 is connected to an installation ring 23. A hexagonal ring 24 is fitted onto the outer wall of the retaining tube 21. A reinforcing sleeve 25 is connected to the side wall of the hexagonal ring 24 and is threadedly connected to the outer wall of the retaining tube 21. A push ring 26 is slidably connected to the outer wall of the retaining tube 21. A thrust bearing 27 is provided between the reinforcing sleeve 25 and the push ring 26. Multiple sets of sliders 28 are provided on the inner wall of the push ring 26. The outer wall of tube 21 has multiple sets of grooves 29 adapted to slider 28. Slider 28 is inserted into and slidably connected to the grooves 29. The outer wall of the retaining tube 21 is threadedly connected to a threaded sleeve 210. The inner wall of the threaded sleeve 210 is provided with a retaining strip 211. The outer wall of the retaining tube 21 is slidably connected to a slip ring 212. The outer wall of the slip ring 212 has a retaining groove 213 adapted to the retaining strip 211. The retaining strip 211 is inserted into the retaining groove 213 and rotatably connected to the retaining groove 213. The side wall of the slip ring 212 has multiple sets of slots 214. Multiple sets of first sliders 215 and second sliders 216 are slidably connected in the inclined groove 22. 5. The first slider 215 is fixedly connected to the second slider 216. The inner sidewall of the first slider 215 has a first locking groove 217, and the inner sidewall of the second slider 216 has a second locking groove 218. Both the first locking groove 217 and the second locking groove 218 are inclined. A first locking block 219 is slidably connected in the first locking groove 217, and a second locking block 220 is slidably connected in the second locking groove 218. The first locking block 219 and the second locking block 220 are fixedly connected. The sidewalls of the first locking block 219 and the second locking block 220 are tightly abutted against the outer sidewall of the cable 11. The outer sidewall of the first locking block 219 is provided with an arc-shaped tube 221. One end of 221 is provided with a plate 222, and multiple sets of elastic plates 223 are provided on the plate 222. The plate 222 is inserted into the slot 214 and slidably connected to the slot 214. An adjustment groove 224 is opened on the outer wall of the first slider 215. The plate 222 is slidably connected to the adjustment groove 224. A retaining plate 225 is provided inside the first slider 215. The retaining plate 225 is slidably connected to the inclined groove 22. The push ring 26 abuts against the side wall of the multiple sets of retaining plates 225. A push spring 226 is provided at the bottom of the retaining plate 225. The push spring 226 is located inside the arc tube 221 and slidably connected to the arc tube 221. The other end of the push spring 226 is fixedly connected to the bottom side wall of the plate 222.

[0033] In this invention, the locking mechanism enables rapid fixing and disassembly of the cable 11. The mounting ring 23 is fixedly connected to the mechanical equipment. Specifically, when it is necessary to fix the cable 11, the cable 11 is first inserted into the retaining tube 21 and connected to the mechanical equipment. Then, the operator first needs to rotate the threaded sleeve 210 according to... Figure 3As shown, the rotation of the threaded sleeve 210 will move left and right along the clamping tube 21. Because the clamping strip 211 is embedded in the clamping groove 213 and rotates and is connected to the clamping groove 213, the rotation of the threaded sleeve 210 will not drive the slip ring 212 to rotate, but will only drive the slip ring 212 to move left and right. The left and right movement of the slip ring 212 can drive the first locking block 219 and the second locking block 220 to move horizontally through the insert plate 222 inserted into the slot 214. Therefore, rotating the threaded sleeve 210 can drive the first locking block 219 and the second locking block 220 to move relative to the first slider 215 and the second slider 216. The compression of the push spring 226 also changes accordingly. The push spring 226 is always in a compressed state. The push spring 226 is set so that the clamping plate 225 always keeps in contact with the side wall of the push ring 26. The insert plate 222 slides horizontally along the adjustment groove 224 and vertically along the slot 214, thereby adjusting the position of the first locking block 219 and the second locking block 220 clamping and locking the surface of the cable 11.

[0034] After the first locking block 219 and the second locking block 220 are adjusted to their horizontal positions, the first slider 215 and the second slider 216 need to be adjusted to drive the first locking block 219 and the second locking block 220 to clamp and fix the outer wall of the cable 11. Specifically, the operator can rotate the hexagonal ring 24 with an external tool. The hexagonal ring 24 drives the reinforcing sleeve 25 to rotate synchronously. The reinforcing sleeve 25 moves left and right along the clamping tube 21 while rotating. When it is necessary to fix the cable 11, the reinforcing sleeve 25 needs to be rotated to the right. Under the action of the thrust bearing 27, the reinforcing sleeve 25 will push the push ring 26 to move synchronously. The push ring 26 pushes multiple sets of clamping plates 225 to the right. The clamping plates 225 drive the corresponding first slider 215 and second slider 216 to slide along the inclined groove 22 towards the end of the inclined groove 22 with a smaller diameter. The multiple sets of first sliders 215 and second sliders 216 gradually tighten. At the same time, according to Figure 9 As shown, because the first locking groove 217 and the second locking groove 218 are inclined, the first slider 215 and the second slider 216 move to the right, and the first locking block 219 and the second locking block 220 will move relative to the first slider 215 and the second slider 216. The first locking block 219 and the second locking block 220 do not move in the horizontal direction, but are pressed and move in the vertical direction, further gradually wrapping and clamping the surface of the cable 11. Continue to rotate the reinforcing sleeve 25 until the cable 11 is fixed and clamped. During the movement of the first slider 215 and the second slider 216, the insert plate 222 slides in the adjusting groove 224, and the push spring 226 is further compressed.

[0035] After the cable 11 is clamped and fixed, if it is pulled by an external force, the cable 11 will cause the first locking block 219 and the second locking block 220 to slide towards the end with the smaller diameter of the corresponding first locking groove 217 and the second locking groove 218, thereby achieving self-locking and preventing the cable 11 from being pulled and damaged. When it is necessary to remove the cable 11, the operator only needs to rotate the reinforcing sleeve 25 in the opposite direction to release the clamping force, thereby releasing the lock on the cable 11 and removing the cable 11.
