[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 3 , the utility model provides a technical solution:

[0027] A building electrical construction threading device, including a bracket 1, the interior of the bracket 1 is movably connected to a rotating shaft 2, the interior of the rotating shaft 2 and the front end of the bracket 1 are jointly provided with a threading assembly 3, the threading assembly 3 includes a driving gear 31 fixedly connected to the front end of the rotating shaft 2, the front end of the driving gear 31 is fixedly connected to a handle 311, the front end of the bracket 1 is movably connected to a rotating rod 32, the front end of the rotating rod 32 is fixedly connected to a driven gear 321, the front end of the driven gear 321 is fixedly connected to a winding wheel 322, the left side of the outside of the bracket 1 is fixedly connected to a fixed block 33, the interior of the fixed block 33 is provided with a guide groove 331, the guide groove 331 extends to the left side of the fixed block 33, and the guide groove 331 extends to the left side of the fixed block 33. A partition plate 332 is fixedly connected inside, and two steel cables 34 are movably connected to the winding wheel 322 and the guide groove 331. The outside of the rotating shaft 2 is fixedly connected to multiple support rods 21, and the outside of the multiple support rods 21 is movably connected to a hollow sleeve 4. The hollow sleeve 4 is annularly wound around the outside of the multiple support rods 21. Round pins 5 are movably connected to the upper and lower ends of the left side of the inside of the fixed block 33. Both of the two round pins 5 pass through the inside of the guide groove 331. Round holes 51 are opened on the outside of the two round pins 5. Both of the two steel cables 34 pass through the inside of the guide groove 331, the hollow sleeve 4, the threading hole 611 and the card slot 621. The two steel cables 34 are separated from the two threading holes 611 by the partition plate 332.

[0028] By adopting the above technical solution, for the wires that need to be protected and wrapped, the wires need to be installed inside the hollow sleeve 4 before the threading work. First, it is necessary to prepare a wire that is longer than the hollow sleeve 4, fix one end of the wire inside the winding wheel 322, and then rotate the handle 311 counterclockwise to drive the driving gear 31 to rotate counterclockwise with the rotating shaft 2 as the axis. The driving gear 31 rotates counterclockwise and drives the winding wheel 322 to rotate counterclockwise through the driven gear 321. As the wire is continuously wound in counterclockwise, the wire is wound around the winding wheel 322. At this time, the wire installation work is ready, one end of the hollow sleeve 4 is fixed to the outside of the support rod 21, and the wire is passed through the guide groove 331 inside the fixing block 33 and then led out from the left end inside the fixing block 33, and then the led-out wire is inserted into the interior of the hollow sleeve 4. At this time, the handle is rotated clockwise again. 311, the clockwise rotation of the handle 311 causes the rotating shaft 2 to rotate clockwise, and the clockwise rotation of the rotating shaft 2 causes the multiple support rods 21 to rotate clockwise, and the hollow sleeve 4 fixed on the outside of the support rod 21 is continuously wound around the outside of the multiple support rods 21, and at the same time, the clockwise rotation of the driving gear 31 causes the driven gear 321 to rotate counterclockwise, and the counterclockwise rotation of the driven gear 321 causes the winding wheel 322 to rotate counterclockwise, and the counterclockwise rotation of the winding wheel 322 continuously moves the wire into the hollow sleeve 4, and continuously rotates to continuously insert the wire into the hollow sleeve 4. When the wire comes out of the other end of the hollow sleeve 4, the work of installing the hollow sleeve 4 on the wire is completed, thereby greatly saving the time for installing the hollow sleeve 4 on the wire, and further ensuring the quality of the wire used for threading work.

[0029] Specifically, such as Figure 4 As shown, the right end of the hollow sleeve 4 is fixedly connected to the swing head assembly 6, and the swing head assembly 6 includes a fixed cylinder 61 fixedly connected to the right end of the hollow sleeve 4, and the left and right ends of the interior of the fixed cylinder 61 are provided with threading holes 611, and the right end of the fixed cylinder 61 is fixedly connected to a spring sheet 62, and the right end of the interior of the spring sheet 62 is provided with two slots 621, and the front and rear ends of the spring sheet 62 are fixedly connected to a first swing block 63 and a plurality of second swing blocks 64, and the opposite surfaces of the front and rear adjacent second swing blocks 64 and the opposite surfaces of the front and rear adjacent first swing blocks 63 are fixedly connected to a plurality of rings 632, and a steering shaft 631 is fixedly connected between the plurality of first swing blocks 63 and the plurality of second swing blocks 64, and the elastic force of the spring sheet 62 is greater than the sum of the gravity of the plurality of first swing blocks 63 and the second swing blocks 64, and the plurality of second swing blocks 64 and the first swing block 63 can swing by 0 to 30 degrees through the steering shaft 631.

[0030] By adopting the above technical solution, when a bifurcated pipe appears in the installation pipe, it is necessary to accurately select a separate installation pipe. First, when installing the wire, the two steel cables 34 need to be reeled into the reel 322 together with the wire, and the two steel cables 34 need to be respectively passed through the circular hole 51 inside the round pin 5. Secondly, the fixing cylinder 61 needs to be fixed to the other end of the hollow sleeve 4. After the installation of the swing head assembly 6 is completed, the two steel cables 34 exposed at one end of the hollow sleeve 4 are respectively passed through the two threading holes 611, and then the steel cables 34 are passed through multiple rings 632 and the card slot 621, and the end that passes through the card slot 621 is knotted for fixation, and then the swing head assembly 6 is inserted into the pipe. As the handle 311 is rotated counterclockwise, it is then rotated through the shaft 2 The hollow sleeve 4 and the wires are transported to the inside of the pipeline with the support rod 21. When a bifurcated pipeline appears inside the pipeline, it is first necessary to rotate the distributed round pin 5 and reel the steel cable 34 around the outside of the round pin 5, thereby reducing the length of the steel cable 34. The length of the steel cable 34 continues to decrease, causing the steel cable 34 to swing toward one side of the steel cable 34 with the spring sheet 62. The swing of the spring sheet 62 is then coordinated through the first pendulum block 63, the second pendulum block 64 and the steering shaft 631, so that the multiple second pendulum blocks 64 and the first pendulum block 63 swing through the multiple steering shafts 631. At this time, the hollow sleeve 4 is moved, thereby achieving the purpose of selecting the pipeline direction, thereby facilitating the threading work in complex pipelines, and thereby improving the efficiency of the entire threading work.

[0031] Working principle: Before threading the wire, the wire needs to be installed inside the hollow sleeve 4. First, you need to prepare a wire that is longer than the hollow sleeve 4, fix one end of the wire inside the winding wheel 322, and then rotate the handle 311 counterclockwise to drive the driving gear 31 to rotate counterclockwise with the rotating shaft 2 as the axis. The driving gear 31 rotates counterclockwise and drives the winding wheel 322 to rotate counterclockwise through the driven gear 321. As the wire is continuously wound counterclockwise, the wire is wound around the winding wheel 322. At this time, the wire installation work is ready, fix one end of the hollow sleeve 4 to the outside of the support rod 21, and pass the wire through the guide groove 331 inside the fixing block 33 and then lead it out from the left end inside the fixing block 33, and then insert the led-out wire into the inside of the hollow sleeve 4. At this time, rotate the handle 311 clockwise again, and the handle 311 The clockwise rotation causes the rotating shaft 2 to rotate clockwise, and the clockwise rotation of the rotating shaft 2 causes the multiple support rods 21 to rotate clockwise. The hollow sleeve 4 fixed on the outside of the support rod 21 is continuously wound around the outside of the multiple support rods 21, and at the same time, the clockwise rotation of the driving gear 31 causes the driven gear 321 to rotate counterclockwise, and the counterclockwise rotation of the driven gear 321 causes the winding wheel 322 to rotate counterclockwise, and the counterclockwise rotation of the winding wheel 322 continuously moves the wire into the hollow sleeve 4. By continuously rotating, the wire is continuously inserted into the hollow sleeve 4. When the wire comes out of the other end of the hollow sleeve 4, the work of installing the hollow sleeve 4 on the wire is completed, thereby greatly saving the time for installing the hollow sleeve 4 on the wire, and further ensuring the quality of the wire used for threading work.
