For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
[0028] Example 1 See also Figures 1 to 8 The present invention provides a flexible steel cable locking device, comprising a fixing seat 1, on which a wire clamp 2 and a fixing device 3 for fixing a steel cable 23 are respectively arranged, control rods 4 are respectively rotatably arranged on the fixing seat 1 located on both sides of the wire clamp 2, the control rods 4 are located on both sides of the wire clamp 2, a connecting rod 5 is rotatably arranged on each control rod 4, a sliding block 6 is rotatably arranged on the movable end of the connecting rod 5, and a wire clamp 2 is arranged on the sliding block 6; The steel cable 23 passes through the fixing device 3 , is wound around the pipe 24 , and then passes through the two wire clamps 2 in sequence, so as to fix the steel cable 23 .
[0029] When the device is in use, first fix one end of the steel cable 23 on the floor slab, and then pass the other end through the fixer 3 and wrap it around the pipe 24. After the wrapping is completed, the two clamps 2 are inserted in sequence to achieve the technical effect of effectively limiting the position of the steel cable 23, regulating its direction and firmly fixing it, so as to ensure that the steel cable 23 maintains a stable state during the use of the pipe 24, and avoids displacement, loosening and other undesirable situations.
[0030] The wire clamp 2 includes a housing 7 fixedly mounted on the fixing seat 1 and the slider 6, and a locking member 8 disposed in the housing 7. The upper portion of the housing 7 is cylindrical, and the lower portion is inverted truncated cone shape. The interior of the housing 7 is hollow, and through holes are respectively provided at the upper and lower ends of the housing 7. The housing 7 is also provided with a lock 9 .
[0031] The locking member 8 includes a push column 10 slidably arranged in the housing 7. The lower part of the push column 10 is in the shape of an inverted truncated cone. A pin hole is provided in the middle part of the push column 10. Three through grooves 11 are provided on the side wall of the pin hole. The through grooves 11 are connected to the outer wall of the inverted truncated cone of the push column 10. A steel ball 12 is movably arranged in each through groove 11.
[0032] A spring 13 is provided between the push post 10 and the housing 7 , one end of the spring 13 is fixedly connected to the housing 7 , and the other end of the spring 13 is fixedly connected to the push post 10 .
[0033] With the coordinated cooperation of the spring 13, the push column 10, the shell 7 and the steel ball 12, the steel cable 23 can only move in one direction in the clamp 2. When the steel cable 23 penetrates into the pin hole of the clamp 2 from the entrance end, it first contacts and collides with the steel ball 12, and forces the steel ball 12 to move outward along the through groove 11, that is, close to the inner wall of the shell 7, by virtue of the radial extrusion force. Due to the spatial constraint of the through groove 11, the steel ball 12 can only move along a predetermined axial trajectory. On the one hand, the inner wall of the shell 7 regulates the movement path of the steel ball 12. On the other hand, when the steel ball 12 is squeezed toward the outer wall, the shell 7 applies a reverse force, prompting the steel ball 12 to fit closely with the steel cable 23, and cooperate with the upward movement of the push column 10 after being subjected to the reaction force of the steel ball 12. With the cooperation of the spring 13, the steel cable 23 is firmly locked, and the friction force increases dramatically, which is sufficient to resist the reverse force, effectively limiting the reverse retreat of the steel cable 23, and realizing one-way movement only along the initial insertion direction.
[0034] When the length of the steel cable 23 needs to be adjusted, the user only needs to manipulate the two handles at the same time to drive the slider 6 to move. When the slider 6 moves upward, the push column 10 is affected by the coordinated mechanism of the housing 7, the spring 13 and the steel ball 12. After the steel cable 23 is inserted into the pin hole, the push column 10 is pushed back by the housing 7. The housing 7 continuously squeezes the steel ball 12, and the multiple steel balls 12 tightly embrace the steel cable 23 to achieve a locking effect on the steel cable 23, so that the steel cable 23 and the slider 6 are relatively fixed. When the slider 6 moves upward, it can drive the steel cable 23 to move upward synchronously. When the slider 6 moves downward, the wire clamp 2 on the fixed seat 1 locks the steel cable 23, so that the fixed seat 1 and the steel cable 23 are relatively fixed. At this time, the slider 6 gradually approaches the fixed seat 1, and this reciprocating movement can realize the adjustment of the steel cable 23 to meet the on-site working conditions during the installation of the electromechanical pipeline 24, ensuring that the steel cable 23 can fit closely to the pipeline 24, effectively bear the weight of the pipeline 24 and limit its displacement.
[0035] The locker 9 includes a wrench 14 rotatably arranged on the housing 7, a lock 15 is fixedly arranged on the wrench 14, and a lock 15 is fixedly arranged on the push column 10; Each locker 15 includes an annular mounting portion, on which two bosses 16 are fixedly disposed. The bosses 16 face the other locker 15 , and one side edge of each boss 16 is a beveled edge.
[0036] When the lock 9 is in the initial state, the bosses 16 of the two locks 15 are staggered, and the push column 10 can slide freely in the housing 7, which is conducive to the flexible adjustment of the position of the steel cable 23; After the adjustment of the steel cable 23 is completed, the wrench 14 on the housing 7 is rotated 90 degrees, and the wrench 14 drives the locking device 15 thereon to rotate synchronously, and the bosses 16 of the two locking devices 15 are opposite to each other; With the help of the boss 16 on the lock 15, when the bosses 16 are opposite to each other, the two bosses 16 conflict with each other to form a mechanical limit. In this state, the push column 10 is firmly restricted in the shell 7 and cannot slide, thereby firmly fixing the steel cable 23. There is no need to worry about the influence of factors such as the operation vibration of the pipeline 24 and accidental interference from external forces, and the electromechanical pipeline 24 can be effectively guaranteed to achieve reliable and long-term suspension installation with the help of the flexible steel cable 23.
[0037] The fixture 3 includes a conical outer sleeve 17 at the lower portion, a guide sleeve 18 is fixedly arranged in the outer sleeve 17, a plurality of slide grooves are arranged in a circumferential array on the body of the guide sleeve 18, a clamping claw 21 is slidably arranged in each slide groove, and the number of the clamping claws 21 is three. The end of the guide sleeve 18 away from the conical portion of the outer sleeve 17 is threadedly connected to the screw rod 19, and the lower end of the screw rod 19 is rotatably arranged with an adjusting platform 20, and a plurality of notches are arranged at the end of the adjusting platform 20 away from the screw 19, and the clamping claw 21 slides in the notches.
[0038] The clamping jaw 21 is in the shape of a right-angled trapezoid, and the oblique side of the clamping jaw 21 is in contact with the tapered portion of the outer sleeve 17 .
[0039] A knob 22 is coaxially fixedly disposed on the screw rod 19; The knob 22 and the middle part of the screw rod 19 are both provided with a passage for the steel cable 23 to pass through.
[0040] Align one end of the steel cable 23 with the channel reserved in the middle of the screw 19 and the knob 22. The through-channel design ensures that the steel cable 23 can pass through it unimpeded. When the steel cable 23 needs to be clamped, the knob 22 is manually turned. When the screw 19 rotates, it drives the adjusting platform 20 to move axially. When the adjusting platform 20 moves, it drives the clamping jaws 21 to move toward the lower end of the outer sleeve 17. Under the action of the beveled edge of the clamping jaws 21 and the tapered portion of the outer sleeve 17, the inner sides of multiple clamping jaws 21 gradually tighten the embrace of the steel cable 23. By virtue of the friction between the clamping jaws 21 and the steel cable 23, the steel cable 23 is firmly fixed inside the fixture 3 to prevent the steel cable 23 from moving or falling out at will, thereby ensuring that the starting end connection of the steel cable 23 is stable and reliable when it is subsequently used as a flexible support structure for the electromechanical pipeline 24.
[0041] When the present invention is used, the device is used, firstly one end of the steel cable 23 is fixed on the floor slab, the other end passes through the fixer 3 and is then wound around the pipe 24, and then the two clamps 2 are inserted in sequence after the winding is completed, so as to achieve the technical effect of effectively limiting the position of the steel cable 23, regularizing the direction and firmly fixing it, ensuring that the steel cable 23 maintains a stable state during the use of the pipe 24, and avoiding displacement, loosening and other undesirable situations.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
