Description

Technical Field

[0001] The invention relates to the field of threading guide equipment, in particular to a cable threading head guide device. Background Art

[0002] Weak current engineering is a classification of power application. Weak current refers to DC circuits or audio, video lines, network lines, and telephone lines. The AC voltage is generally within 36V. In the field of weak current engineering, it is often necessary to pass cables through walls, electrical cabinet walls, etc. to achieve signal transmission or wiring purposes. In order to protect the cables from mechanical or chemical damage, the cables are usually inserted into steel pipes to ensure the safe use of the cables. The existing technology uses a guide device connected to the traction rope, and the guide device drives the traction rope to pass into the steel pipe.

[0003] According to a cable threading head guiding device disclosed in the existing patent document with publication number CN208423635U, it includes a threading body composed of a semi-spherical head and a cylinder, a chamfer is provided at the periphery of the lower end of the cylinder, a threading hole is axially opened at the center position of the lower end surface of the cylinder, and a countersunk threading top screw hole and a countersunk threading fixing screw hole are respectively opened radially at the symmetrical positions of the cylindrical surfaces on both sides of the middle of the cylinder, and the inner diameter of the countersunk threading fixing screw hole is larger than the inner diameter of the countersunk threading top screw hole, and the threading top screw is screwed into the countersunk threading top screw hole. When used, this technical scheme reduces the friction between the threading steel wire head and the inner wall of the steel pipe, so that the threading steel wire passes through the steel pipe and the bending part of the steel pipe quickly and smoothly, thereby improving the efficiency of the cable threading work. With respect to the above technical scheme, although this scheme reduces the friction, it needs to be squeezed and fixed by bolts when fixing the cable, and the speed is slow during installation and the squeezing position cannot be adaptively adjusted according to the diameter of the cable, which is inconvenient when used. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a cable threading head guide device to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. When in use, the upper arc seat and the lower arc seat cooperate with each other to facilitate the fixed seat to penetrate into or out of the steel pipe. The arc seat reduces the friction between the steel pipe and the arc seat drives the steel wire to enter the interior of the steel pipe first to realize the subsequent installation of the cable. The cable is inserted into the limiting hole, and the cable and the ring seat are squeezed and limited under the pull of the limiting seat, thereby facilitating the rapid installation of the cable in the later stage. According to the different diameters of the cable, the limiting seat and the ring seat cooperate to realize the extrusion and fixation of the cable.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] See also Figures 1 to 6 The present invention provides a technical solution: a cable threading head guiding device, comprising a fixed seat 1, an upper arc seat 2 is welded on the top of the fixed seat 1, a lower arc seat 3 is welded on the bottom of the fixed seat 1, a fixing hole 4 is opened on the side of the fixed seat 1, a fixing column 5 is movably installed inside the fixing hole 4, an opening 7 is opened between the fixed seat 1, the upper arc seat 2 and the lower arc seat 3, a steel wire 8 and a cable 21 are movably installed inside the opening 7, the steel wire 8 provides tension for the movement of the fixed seat 1, and the cable 21 is guided to move inside the steel pipe through the tension of the steel wire 8.

[0027] In this embodiment, one end of the steel wire 8 is fixed to a limiting seat 9, and a limiting groove 10 and a fixing groove 11 are respectively provided on the limiting seat 9, and the fixing groove 11 is distributed between the limiting grooves 10, and a limiting hole 12 is provided at one end of the fixing groove 11, and the limiting holes 12 are cross-distributed inside the limiting seat 9, a slider 13 is welded on the side of the fixing column 5, and a slide groove 16 is provided on the inner wall of the fixing hole 4, and the slider 13 is movably installed inside the slide groove 16 through a supporting mechanism 14, and the supporting mechanism 14 is a supporting spring, which pushes the fixing column 5 to move outward, and the fixing column 5 moves outward to realize the contact support between the ball 6 and the inner wall of the steel pipe, thereby realizing the later movement of the arc seat inside the steel pipe.

[0028] In this embodiment, an installation cavity 17 is opened at one end of the fixed column 5, and a reset mechanism 18 is fixed inside the installation cavity 17. The extrusion column 15 is movably installed on the fixed column 5. A positioning hole is opened between the opening 7 and the fixed hole 4. The extrusion column 15 is movably installed inside the positioning hole. The extrusion column 15 is fixedly installed at one end of the reset mechanism 18. A limiting ring 19 and a ring seat 20 are welded on the inner wall of the opening 7. The limiting ring 19 cooperates with the steel wire 8, and the ring seat 20 cooperates with the limiting seat 9. The reset mechanism 18 is a reset spring. After the extrusion column 15 squeezes the reset mechanism 18, it squeezes the cable 21. When the fixed column 5 moves at different distances, the extrusion column 15 contacts the cable for extrusion and limiting.

[0029] In this embodiment, a protrusion 22 is welded on the inner wall of the opening 7, and the protrusion 22 is movably installed inside the limiting groove 10. The cable 21 is movably installed inside the fixing groove 11 and the limiting hole 12. One end of the cable 21 is in contact with the ring seat 20. An arc groove is opened at one end of the fixing column 5. A ball 6 is rotatably installed inside the arc groove. The ball 6 moves inside the steel pipe to reduce friction, thereby facilitating the overall movement of the fixing seat 1.

[0030] When the device is in use, one end of the steel wire 8 is passed upward from the bottom of the ring seat 20 through the ring seat 20 and the limiting ring 19. The limiting ring 19 contacts the outer wall of the steel wire 8 at a later stage. The limiting ring 19 supports the steel wire 8 that stays inside the opening 7 to prevent the steel wire from bending between the upper arc seat 3 under the push. When in use, the steel wire 8 is moved downward, and the steel wire 8 pushes the limiting seat 9 to move out from the bottom of the lower arc seat 3. After the limiting seat 9 is moved out, one end of the cable 21 is passed through the limiting hole 12, so that one end of the cable 21 is bent and then installed in the fixing groove 11. After one end of the cable 21 is installed, the steel wire 8 drives the limiting seat 9 to move upward and re-enter the inside of the opening 7. When the steel wire 8 is pulled, the cable 21 at the bending position of the limiting hole 12 contacts the bottom of the ring seat 20. With the pulling force of the steel wire 8, the limiting seat 9 squeezes the cable 21 at the bottom of the ring seat 20 for limiting fixation, and no external bolts are required to achieve the connection between the cable 21 and the limiting seat 21 After the cable 21 is fixed, the starting end of the steel wire 8 is pulled, so that the steel wire 8 drives the fixing seat 1 to enter the interior of the steel pipe. After the fixing seat 1 enters the interior of the steel pipe, the fixing column 5 is squeezed according to the diameter of the steel pipe. After the fixing column 5 is squeezed, the fixing seat 1 enters. After entering, the thrust of the supporting mechanism 14 makes the ball 6 at one end of the fixing column 5 contact the inner wall of the steel pipe. The fixing column 5 makes the fixing seat 1 suspended and installed inside the steel pipe. When the fixing seat 1 moves, the blockage caused by the tilting between the upper arc seat 2 or the lower arc seat 3 and the steel pipe is avoided. When the fixing column 5 moves, the squeezing column 15 enters the interior of the positioning hole. The movement of the squeezing column 15 squeezes and fixes the cable 21 inside the fixing groove 11 again. The squeezing column 15 squeezes the reset mechanism 18 and then squeezes the cable 21. When the fixing column 5 moves at different distances, the squeezing column 15 contacts the cable to squeeze and limit, thereby avoiding the impact caused by the cable 21 falling off the limiting seat 9 during movement.
