Description

Technical Field

[0001] This invention relates to the field of cable clamps, and more particularly to a load-bearing, anti-slip cable clamp. Background Technology

[0002] Cable securing is a fundamental step in the installation of transmission lines and electrical equipment, and the reliability of the clamping directly affects line safety and system stability. In overhead installations, cable tray crossings, or vibrating environments, cable clamps must withstand multiple loads over long periods, including the cable's own weight, wind loads, thermal expansion and contraction, and accidental dragging, to prevent cable slippage or detachment. Due to the diverse specifications of cables, complex operating conditions, and dynamic load variations, an ideal clamp must possess continuous and stable anti-slip clamping force and good environmental adaptability.

[0003] Traditional cable clamps generally suffer from drawbacks such as reliance on initial pre-tightening for anti-slip performance and insufficient resistance to dynamic loads. Their clamping force typically comes solely from the initial pre-tightening of the bolts. If the cable is subjected to vertical gravity or continuous vibration, the static friction between the clamp and the cable may be insufficient, causing the cable to gradually slip. Furthermore, the bolt locking mechanism is prone to loosening under long-term vibration, resulting in a decrease in clamping force and requiring frequent maintenance and tightening. In addition, common clamps have relatively limited functionality, lacking integrated considerations for auxiliary functions such as cable heat dissipation, mounting base cushioning, and interface sealing, making them ill-suited for applications requiring heavy loads, humidity, or precise positioning. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a load-bearing and anti-slip cable clamp in view of the above-mentioned defects in the prior art.

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a load-bearing anti-slip cable clamp to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A load-bearing, anti-slip cable clamp includes: a clamp base, an upper pressure cover, and a locking bolt. The clamp base and the upper pressure cover are hinged together by a hinge shaft. The locking bolt is used to lock the upper pressure cover and the clamp base together. The clamp is characterized by further comprising: A support base is disposed below the clamp; A clamping mechanism is provided inside the clamp and the upper pressure cover; The clamping mechanism includes a linkage component and a load-bearing conversion component; One end of the linkage component is engaged with the end of the locking bolt; The load-bearing conversion component is disposed between the load-bearing base and the linkage component; When the locking bolt is tightened, the linkage assembly converts the axial locking force of the locking bolt into a first radial clamping force on the cable; When the cable is subjected to downward pressure from gravity, the load-bearing conversion component transfers the weight of the cable to the linkage component, causing the linkage component to generate a second radial clamping force on the cable. An anti-loosening mechanism is provided between the locking bolt and the upper pressure cover. The anti-loosening mechanism includes a pre-tightening element and a locking component. The pre-tightening element is sleeved on the locking bolt and abuts against the head of the locking bolt and the upper pressure cover. The locking component is provided at the hinge shaft and is connected to the upper pressure cover and the clamp.

[0007] Preferably, the linkage component includes a first lever, a second lever, and a connecting rod; The first lever is rotatably disposed in the middle of the clamp; The second lever is rotatably disposed in the middle of the upper pressure cover; The two ends of the connecting rod are respectively hinged to one end of the first lever and one end of the second lever, wherein the other end of the first lever abuts against the end of the locking bolt, and the other end of the second lever is provided with a clamping block.

[0008] Preferably, the clamping block has a first arc surface on the side facing the cable; The clamp is provided with a second arc surface at the position corresponding to the first arc surface; The first arc surface is fitted with a first anti-slip component, and the second arc surface is fitted with a second anti-slip component; The first anti-slip component and the second anti-slip component are respectively connected to the first arc surface and the second arc surface through a dovetail groove structure.

[0009] Preferably, the load-bearing conversion assembly includes a top column, a slide block, and a transmission rod; The top column is vertically arranged, with its lower end connected to the bearing base and its upper end abutting against the bottom of the clamp. The slide block is slidably disposed in the slide groove opened in the clamp and contacts the upper end of the top column; One end of the transmission rod is hinged to the slide block, and the other end abuts against the force-bearing end of the first lever.

[0010] Preferably, the locking component includes a fixed ratchet and a movable pawl. The fixed ratchet is sleeved on the hinge shaft, and the movable pawl is movably connected to the upper pressure cover and engages with the fixed ratchet when the upper pressure cover is closed.

[0011] Preferably, the movable claw includes a claw body and a reset member. The claw body is hinged to the upper pressure cover, and the reset member is disposed between the claw body and the upper pressure cover, so that the claw body has a tendency to engage with the fixed ratchet. The movable jaw is connected to an unlocking mechanism, which drives the jaw to overcome the force of the reset mechanism and thus separate from the fixed ratchet.

[0012] Preferably, the bearing base includes a base plate and multiple stiffening plates; The base plate is used to fix it to the bearing base surface; Multiple stiffening plates are arranged at intervals and positioned between the base plate and the bottom of the clamp.

[0013] Preferably, the base plate has a strip-shaped hole, and scale markings are provided on both sides of the strip-shaped hole; An elastic layer is provided between the stiffening plate and the bottom of the clamp, and a protective sleeve covers the outer periphery of the elastic layer.

[0015] Preferably, the inner bottom wall of the clamp is provided with a positioning ridge, which extends along the axial direction of the cable; The mating surfaces of the clamp and the upper pressure cover are respectively provided with sealing grooves and sealing strips.

[0016] The present invention adopts the above technical solution and has the following technical effects compared with the prior art: 1. Adaptive anti-slip for more reliable clamping: Through the cooperation of the linkage and load-bearing conversion components, the clamp can automatically increase the clamping force by utilizing the cable's own weight after initial locking, effectively preventing slippage under heavy load or vibration.

[0017] 2. Double anti-loosening, safe and stable: The pre-tightening element at the locking bolt and the mechanical locking mechanism at the hinge shaft work together to effectively resist loosening caused by vibration, prevent the top cover from accidentally popping open, and ensure long-term stability.

[0018] 3. Stable structure and shock absorption: The load-bearing base is designed to be stable and easy to adjust. The internal elastic layer can buffer impact and vibration, protecting the cable and clamp structure.

[0019] 4. Promotes heat dissipation and enhances protection: The optimized ventilation structure helps the cable dissipate heat, while the combination of the guide plate and interface seal can effectively prevent dust and moisture.

[0020] 5. Easy maintenance and user-friendly interface: Anti-slip parts can be replaced individually, reducing maintenance costs; positioning edges facilitate installation and alignment; the locking mechanism has a convenient unlocking function and is easy to operate. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] As attached Figures 1 to 10 The cable clamp shown is a load-bearing, anti-slip type. The clamp base 1 is an overall U-shaped shell structure with an upward opening. A positioning ridge 107 extending along the cable axial direction is provided on the bottom inner wall of the clamp base 1. The top of the positioning ridge 107 is arc-shaped, and guide slopes for limiting the cable are formed on both sides of the positioning ridge 107. Multiple ventilation holes 105 are symmetrically opened on both side walls of the clamp base 1. A guide plate 106 is fixedly connected to the wall of each ventilation hole 105. The surface of the guide plate 106 extends obliquely from the edge of the ventilation hole 105 towards the outside of the clamp base 1. A sealing groove 108 is machined around the inner cavity of the clamp base 1. The cross-sectional shape of the sealing groove 108 is U-shaped. One side of the clamp base 1 is open to… The hinge shaft 101 is connected to the upper pressure cover 2. Both ends of the hinge shaft 101 are fixed to the ear plates of the clamping seat 1 and the upper pressure cover 2 by retaining rings. The clamping seat 1 has a second arc surface 102 machined inside corresponding to the position of the clamping block 5014. The second arc surface 102 is fitted with a second anti-slip part 103 through the dovetail groove structure 5017. The bottom inner side of the clamping seat 1 is also machined with a sliding groove 104 for the sliding seat 5022 to slide. In addition, a protruding cavity is formed on the front inner wall of the clamping seat 1 at the position corresponding to the locking bolt 3. This cavity is isolated from the main inner cavity used to accommodate the cable. That is, the protruding cavity does not occupy the space formed by the clamping seat 1 and the upper pressure cover 2 for the cable to pass through.

[0027] The upper cover 2 is a cover structure adapted to the opening of the clamp 1. The inner side of the upper cover 2 is equipped with a first anti-slip component 5016 through a pressing block 5014 at the position corresponding to the second arc surface 102. The end face of the upper cover 2 is fixed with a sealing strip 201 corresponding to the position of the sealing groove 108. The sealing strip 201 is made of elastic material. When the upper cover 2 is rotated and closed around the hinge shaft 101, the sealing strip 201 gradually approaches and is finally pressed into the sealing groove 108. The inner side of the upper cover 2 is equipped with a complementary protrusion structure corresponding to the position of the protruding cavity of the clamp 1, so that when the upper cover 2 is closed, the two together form a closed space. The upper cover 2 is also equipped with a movable part of the locking component 602, such as a movable claw 6022.

[0028] The screw of the locking bolt 3 passes through the threaded hole at the top of the upper pressure cover 2, and its end extends into the space formed by the closing of the clamp 1 and the upper pressure cover 2, and contacts the first lever 5011 of the linkage assembly 501; a pre-tightening element 601 is installed between the head of the locking bolt 3 and the upper pressure cover 2; when the locking bolt 3 is rotated, its screw moves downward and its end pushes the linkage assembly 501.

[0029] The support base 4 is located directly below the clamp 1 and is mainly composed of a base plate 401 and multiple stiffening plates 402. The base plate 401 is a flat plate structure with strip holes 403 for installation and adjustment. Scale markings 404 are etched next to the strip holes 403. Multiple stiffening plates 402 are vertically welded to the base plate 401 and are evenly spaced along the length of the bottom of the clamp 1. The top of the stiffening plates 402 is connected to the bottom of the clamp 1 through an elastic layer 405. A protective sleeve 406 is wrapped around the elastic layer 405.

[0030] The clamping mechanism 5 includes a linkage assembly 501 and a force-bearing conversion assembly 502. The first lever 5011 and the second lever 5012 of the linkage assembly 501 are respectively mounted inside the clamping seat 1 and the upper pressure cover 2 via rotating shafts, and are hinged together by a connecting rod 5013. The actuating end of the first lever 5011 contacts the end of the locking bolt 3, and its force-bearing end is connected to the second lever 5012 via the connecting rod 5013. A clamping block 5014 is mounted on the other end of the second lever 5012. The clamping block 5014 has a first arc surface 5015 and a first anti-slip element 5016 embedded on it. When the locking bolt 3 is screwed in, its end pushes the first lever 5011 to rotate. The first lever 5011 pulls the second lever 5012 via the connecting rod 5013, causing the clamping block 5014 to press radially against the cable.

[0031] The top column 5021 of the load-bearing conversion assembly 502 is vertically connected between the bottom of the bearing base 4 and the clamp 1; the slide 5022 is placed in the slide groove 104 in the clamp 1 and contacts the upper end of the top column 5021; one end of the transmission rod 5023 is hinged to the slide 5022, and the other end abuts against the first lever 5011. The arc surface of the other end of the transmission rod 5023 then pushes upward against the lower surface of the force-bearing end of the first lever 5011, causing the first lever 5011 to rotate around its axis, increasing the downward pressure of its working end on the locking bolt 3, and thus generating additional clamping force on the clamping block 5014 through the linkage assembly 501. When the cable's gravity presses down on the clamp 1, the clamp 1 moves downward relative to the top post 5021. The upper end of the top post 5021 pushes the slide block 5022 to slide in the slide groove 104. The slide block 5022 drives the transmission rod 5023 to swing. The transmission rod 5023 pushes the first lever 5011 to rotate, which in turn causes the clamping block 5014 to generate additional clamping force through the linkage component 501.

[0032] The anti-loosening mechanism 6 includes a preload element 601 fitted onto the locking bolt 3 and a locking component 602 located at the hinge shaft 101. The preload element 601 is a disc spring or a coil spring, which continuously provides tension to prevent the bolt from reversing. The locking component 602 consists of a fixed ratchet 6021 and a movable pawl 6022. The fixed ratchet 6021 is fixed to the hinge shaft 101. The movable pawl 6022 includes a pawl body 6023, a reset member 6024, and an unlocking operation member 6025. The pawl body 6023 is hinged to the upper cover 2, and under the elastic force of the reset member 6024, its end teeth tend to engage with the fixed ratchet 6021. The unlocking operation member 6025 is a lever connected to the pawl body 6023. When the upper cover 2 is closed, the pawl body 6023 automatically engages with the fixed ratchet 6021 to prevent the upper cover 2 from opening in reverse. Operating the unlocking operation member 6025 can overcome the force of the reset member 6024, causing the pawl body 6023 to disengage from the fixed ratchet 6021, thereby allowing the upper cover 2 to open.

[0033] The specific process is as follows: The operator places the cable on the second anti-slip part 103 of the clamp 1, closes the upper pressure cover 2 so that its sealing strip 201 is embedded in the sealing groove 108 of the clamp 1. Tighten the locking bolt 3, and its end presses down on the working end of the first lever 5011 of the linkage assembly 501. The lever rotates around the axis, and drives the second lever 5012 through the connecting rod 5013, which drives the pressing block 5014 and the first anti-slip part 5016 at its end to radially press the cable, generating an initial clamping force. After locking, the pre-tightening element 601 of the anti-loosening mechanism 6 provides a continuous upward tension to the locking bolt 3 to prevent its threaded pair from loosening; at the same time, the claw body 6023 of the locking part 602 engages with the fixing ratchet 6021 under the action of the reset part 6024 to prevent the upper pressure cover 2 from accidentally opening in reverse around the hinge axis 101. When the cable is subjected to downward pressure, the pressure is transmitted to the bearing base 4 through the clamp 1, causing the bottom of the clamp 1 to slightly shift downward at the top post 5021. The reaction force of the top post 5021 is transmitted through the bottom wall of the slide groove 104 at the bottom of the clamp 1, driving the slide 5022 to slide within the slide groove 104. This causes the transmission rod 5023 to push the force-bearing end of the first lever 5011 upward, resulting in a greater downward pressure on the locking bolt 3 at the action end of the first lever 5011. Consequently, the linkage component 501 generates an additional radial clamping force on the clamping block 5014, achieving adaptive tightening. Thus, the clamp completes the entire workflow of installation, initial locking, adaptive tightening under load, and double anti-loosening.

[0034] Example 2

[0035] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 10 As shown below, see details: Furthermore, the first lever 5011 is rotatably mounted in the clamp 1 via a first pivot, with both ends of the first pivot supported in shaft holes on the inner wall of the clamp 1; the end of the first lever 5011 closest to the locking bolt 3 is defined as the actuating end, which is configured to make spherical contact with the end of the locking bolt 3; the end of the first lever 5011 furthest from the locking bolt 3 and connected to the force conversion assembly 502 is defined as the bearing end, which is provided with a first hinge hole; the second lever 5012 is rotatably mounted in the upper cover 2 via a second pivot, the second pivot being installed in the same manner as the first pivot, and one end of the second lever 5012 is provided with a second hinge hole; connecting rod 501 The two ends of 3 are respectively inserted into the first hinge hole and the second hinge hole through the first hinge pin and the second hinge pin, thereby realizing the hinge; the clamping block 5014 is installed on the other end of the second lever 5012 by bolt fastening; when the locking bolt 3 is tightened, its end pushes the force-bearing end of the first lever 5011 axially, causing the first lever 5011 to rotate around the first rotating shaft. The first lever 5011 drives the first hinge hole at its end to move, and then pulls the second hinge hole at one end of the second lever 5012 through the connecting rod 5013, causing the second lever 5012 to rotate around the second rotating shaft. The movement of the end of the second lever 5012 is finally converted into the linear clamping movement of the clamping block 5014 on the cable.

[0036] Furthermore, the dovetail groove structure 5017 includes dovetail-shaped channels provided on the first arc surface 5015 and the second arc surface 102, and dovetail-shaped protrusions formed on the back of the first anti-slip member 5016 and the second anti-slip member 103, with the dovetail-shaped protrusions and the dovetail-shaped channels interlocking with each other; the back of the first anti-slip member 5016 is also provided with multiple reinforcing ribs connected to the dovetail-shaped protrusions; when the clamping block 5014 is driven to move radially, the first anti-slip member 5016 moves smoothly along with it through the guidance of the dovetail groove structure 5017, and its reinforcing ribs evenly transmit the clamping force to the entire anti-slip member body, so that the anti-slip texture curved surface of the first anti-slip member 5016 closely fits the cable surface, while the second anti-slip member 103 is fixed to the clamping seat 1 through the same dovetail groove structure 5017 to provide stable reaction support, and the two work together to achieve anti-slip clamping.

[0037] Furthermore, the top column 5021 is vertically positioned, with its lower end fixed to the bearing base 4, and its upper end spherical, abutting against the bottom of the clamp 1. The slide block 5022 is slidably positioned in the groove 104 opened within the clamp 1, with the extension direction of the groove 104 perpendicular to the axial direction of the top column 5021. When the cable presses down on the clamp 1 due to its own weight, the bottom shell of the clamp 1 experiences a slight downward displacement at the top column 5021. The vertical upward reaction force provided by the top column 5021 is transmitted through the bottom wall of the groove 104, thereby driving the slide block 5022 to slide along the groove 104 towards the first lever 5011. The slide 5022 pushes the transmission rod 5023 through the pin, causing the transmission rod 5023 to rotate around its hinge point. The arc surface at the other end of the transmission rod 5023 then pushes the force-bearing end of the first lever 5011, thereby converting the downward pressure of the cable into a thrust on the first lever 5011.

[0038] Specifically, when the cable is subjected to gravity pressing down on the clamp 1, the clamp 1 tends to move downward relative to the top post 5021. The slide 5022 is subjected to the reaction force of the upper end of the top post 5021 in the slide groove 104, thereby sliding towards the first lever 5011.

[0039] Furthermore, the fixed ratchet 6021 is sleeved on the hinge shaft 101 and circumferentially fixed to the hinge shaft 101 by a flat key; the movable pawl 6022 is connected to the upper cover 2 by a support shaft, so that the movable pawl 6022 can rotate relative to the upper cover 2 around its support shaft; the end of the movable pawl 6022 is provided with pawl teeth that are adapted to the tooth shape of the fixed ratchet 6021; when the upper cover 2 rotates around the hinge shaft 101 in the closing direction, the movable pawl 6022 swings downward under the action of gravity or the built-in torsion spring, so that the pawl teeth at its end fall into the tooth groove of the fixed ratchet 6021; when the upper cover 2 is accidentally subjected to an external force in the opening direction, the pawl teeth of the movable pawl 6022 abut against the tooth surface of the fixed ratchet 6021, preventing the fixed ratchet 6021 and the hinge shaft 101 and the upper cover 2 connected thereto from reversing, thereby achieving locking.

[0040] Furthermore, the claw body 6023 is hinged to the upper pressure cover 2 via a shaft, allowing the claw body 6023 to rotate around the shaft. The reset component 6024 is a torsion spring sleeved on the shaft, with one end of the torsion spring abutting against the upper pressure cover 2 and the other end abutting against the claw body 6023, providing the claw body 6023 with an elastic force that causes the claw teeth at its end to press against the fixed ratchet 6021. The unlocking operation component 6025 is an operating lever, with its middle part hinged to the upper pressure cover 2. One end of the operating lever extends to a position for easy operation, and the other end of the operating lever contacts the claw body 6023. When unlocking is required, pressing the extended end of the operating lever causes the operating lever to rotate around its middle hinge point, and its other end pushes the claw body 6023, causing the claw body 6023 to overcome the elastic force of the torsion spring and rotate around its own shaft, thereby separating the claw teeth at the end of the claw body 6023 from the grooves of the fixed ratchet 6021.

[0041] Furthermore, the base plate 401 is configured as a rectangular plate structure with mounting holes at its four corners for inserting fixing bolts; multiple stiffening plates 402 stand vertically on the upper surface of the base plate 401 and are arranged parallel to each other at intervals along the length of the bottom of the clamp 1; the upper edge of the stiffening plate 402 is fixedly connected to the bottom of the clamp 1 by welding or bolts, and the lower edge of the stiffening plate 402 is fixedly connected to the upper surface of the base plate 401; the surface of the stiffening plate 402 is configured as a corrugated shape to enhance rigidity or is provided with reinforcing ribs; when the weight of the cable acts on the clamp 1, the downward pressure is evenly distributed to each stiffening plate 402 through the bottom of the clamp 1, and the stiffening plate 402 transmits the force vertically downward to the base plate 401, and finally the base plate 401 distributes it to the bearing base surface through the fixing bolts.

[0042] Furthermore, the strip-shaped hole 403 on the base plate 401 is an elongated oval through hole, extending along the length of the base plate 401; the scale markings 404 are etched or printed on the edges of both sides of the strip-shaped hole 403, and the scale markings 404 are marked with units of length; the elastic layer 405 between the stiffening plate 402 and the bottom of the clamp 1 is made of rubber or silicone material, and the elastic layer 405 completely pads between the upper surface of the stiffening plate 402 and the bottom of the clamp 1; the protective sleeve 406 is made of flexible waterproof material. 06 tightly wraps around the upper area of ​​the elastic layer 405 and the stiffener 402, and is fixed by a strap or hook and loop fastener; when the fixing bolt is installed through the strip hole 403, the scale mark 404 is used to indicate and accurately position the bolt in the strip hole 403; when the cable presses down on the clamp 1 due to its own weight, the bottom of the clamp 1 compresses the elastic layer 405, and the elastic layer 405 undergoes slight deformation to buffer and disperse the pressure. At the same time, the protective sleeve 406 covering it undergoes adaptive deformation but always maintains the sealing protection of the elastic layer 405.

[0043] Furthermore, ventilation holes 105 are evenly distributed on the side wall of the clamp 1, and the ventilation holes 105 are circular or elliptical through holes; the guide plate 106 is a sheet structure, and one edge of it is fixedly connected to the hole wall of the ventilation hole 105. The plate body of the guide plate 106 extends obliquely from the connection point to the outer space of the clamp 1, and its end bends away from the center of the clamp 1 to form an arc or hook shape; when the external air flows through the clamp 1, the airflow is guided by the oblique plate body of the guide plate 106 and changes direction. Part of the airflow is directed to the inlet of the ventilation hole 105, thereby increasing the airflow flow through the interior of the clamp 1 to enhance heat dissipation; at the same time, dust or water droplets that may drift from the outside of the clamp 1 to the ventilation hole 105 will first hit the end of the outwardly bent guide plate 106 and be blocked or guided away from the inlet of the ventilation hole 105.

[0044] Furthermore, a positioning ridge 107 protrudes from the center of the inner bottom wall of the clamp 1. The cross-section of the positioning ridge 107 is triangular or trapezoidal, and its top extends along the axial direction of the cable to form a long strip-shaped protrusion. A sealing groove 108 is formed around the mating end face of the clamp 1. The cross-section of the sealing groove 108 is rectangular or U-shaped. A sealing strip 201 is fixedly embedded in the mating end face of the upper pressure cover 2. The shape of the sealing strip 201 is adapted to the sealing groove 108 and is made of elastic material. When the cable is placed into the clamp 1, the bottom of the cable is embedded with two... Parallel positioning ridges 107 are positioned between each other or against the side of a single positioning ridge 107, thereby limiting the lateral displacement of the cable. When the upper pressure cover 2 rotates and closes around the hinge shaft 101, the mating end face of the upper pressure cover 2 gradually approaches the mating end face of the clamp 1, and the sealing strip 201 is aligned and embedded in the sealing groove 108. Under the final locking force of the locking bolt 3, the sealing strip 201 is compressed in the sealing groove 108 and undergoes elastic deformation, thereby filling the gap between the mating end faces of the clamp 1 and the upper pressure cover 2 to form a seal.
