[0002] In view of the crisscrossing lines in the existing communication room, when wiring under the anti-static floor in the room, the floor needs to be pried open and the cables to be laid from one end to the other. In places where the floor cannot be pried open, operators need to pull the cables from one end to the other with their hands. In the case of wall wiring and deep cable trenches, there are already a large number of cables in the original cable troughs, which are easily entangled with other cables during the threading process, or cause damage to the cables; Prior art, such as a Chinese patent with announcement number CN113097927B, proposes a wire threader for a communication room, comprising a wire threader body, a replacement head and a guide, wherein the replacement head is plugged into the top of the wire threader body, and an open groove is longitudinally penetrated on the replacement head, and the open groove is used to thread the cable; the guide comprises a fixed sleeve sleeved on the replacement head and a guide head arranged at the upper end of the fixed sleeve, the open groove is communicated with the inner cavity of the fixed sleeve, and a positioning cavity is provided inside the guide head for fixing the connector of the cable which is communicated with the inner cavity of the fixed sleeve. In the patent document: the bottom of the replacement head is plugged into the wire threader body, the cable is threaded on the open groove, the guide and the open groove cooperate to clamp the cable and clamp the cable connector, and the cable is driven to pass through the surrounding laid cables to reach the target position by pushing the wire threader body, which saves time and effort and will not cause damage to the cable.

[0003] However, although the above patent document solves the threading function, it is difficult to solve the difficulty of threading multiple wire harnesses at the same time. The prior art generally adopts a spring-like threader, which is manually pushed to drive the multiple wire harnesses. However, when routing the wires, it is not only necessary to manually pinch the threader, but also to push the threader to achieve routing, which makes threading difficult. Therefore, it is necessary to design a machine room threader to solve this technical problem. Summary of the invention

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention. Example

[0019] See also Figure 1 and Figure 3 The present invention provides a technical solution: a machine room wire threader, comprising a bending spring rod 3, a fixed sleeve 2 and a movable sleeve 1 slidably sleeved outside the fixed sleeve 2. The cable passes through the fixed sleeve 2 and is connected to the end of the bending spring rod 3. A roller 301 is installed at the other end of the bending spring rod 3. During the threading process, the cooperation between the bending spring rod 3 and the roller 301 can assist in threading through bends and avoid cable blockage when passing through bends.

[0020] Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The outer tube wall of the movable sleeve 1 is equipped with a movable ring 101 that slides along the length direction of the movable sleeve 1 and a fixed ring 102 that is fixedly installed on the outside of the movable sleeve 1. A plurality of movable grooves 1011 that are arranged in an annular array and radially along the movable ring 101 are opened on the side of the movable ring 101 away from the fixed ring 102, and a movable plate 103 is slidably installed inside the movable groove 1011. The movement mode of the movable plate 103 relative to the movable ring 101 is only radial movement along the movable ring 101. A return spring column 1012 is fixedly connected between the movable plate 103 and the inner wall of the movable groove 1011. A fixed plate 106 corresponding to the movable plate 103 is fixedly connected to the circumferential outer wall of the fixed ring 102, and a fixed wedge 1061 and a movable wedge 1031 that are in sliding contact are respectively installed at the ends of the fixed plate 106 and the movable plate 103 that are close to each other. Telescopic guide columns 105 distributed in an annular array are fixedly installed between the fixed ring 102 and the movable ring 101.

[0021] The movement of the movable ring 101 can drive the movable plate 103 to move along the length direction of the sleeve, so that the movable wedge block 1031 on the movable plate 103 is in sliding contact with the fixed wedge block 1061 on the fixed plate 106, so that the movable plate 103 can move radially along the movable ring 101 and squeeze the reset spring column 1012. When the movable ring 101 moves to the telescopic guide column 105 and cannot be telescoped, the telescopic guide column 105 and the fixed ring 102 are pushed at this time, and the movable sleeve 1 is driven to move in the length direction of the fixed sleeve 2 through the fixed ring 102.

[0022] Reference Figure 1 , Figure 3 and Figure 6 The end of the movable plate 103 extends to the outside of the movable groove 1011 and is fixedly connected to a connecting rod 104 which is perpendicular to the movable plate 103 , and the other end of the connecting rod 104 is fixedly connected to a driving rack 107 , and the end of the driving rack 107 extends to the inside of the fixed sleeve 2 .

[0023] Reference Figure 3 and Figure 5-Figure 7A mounting plate 202 corresponding to the driving rack 107 is fixedly mounted at the end of the fixed sleeve 2, and a wiring mechanism cooperating with the driving rack 107 is provided on one side of the mounting plate 202 close to the center of the cross-section of the fixed sleeve 2. The wiring mechanism includes two driven rods 2021 rotatably mounted on the mounting plate 202 in pairs and perpendicular to the mounting plate 202. The rod body of the driven rod 2021 is fixedly sleeved with a driven toothed disc 2022 meshing with the driving rack 107, and the end of the driven rod 2021 is fixedly connected with a wiring wheel 2023 for cable routing.

[0024] The specific implementation of the machine room threader is as follows: First, the cables to be threaded are respectively passed through between the paired routing wheels 2023, and then the movable ring 101 is pushed, so that the movable ring 101 drives the movable plate 103 to move, and the movable ring 101 shortens the telescopic guide column 105, and at the same time, the movable wedge 1031 on the movable plate 103 is in sliding contact with the fixed wedge 1061 on the fixed plate 106, so that the movable wedge 1031 pushes the movable plate 103 to slide inside the movable groove 1011, and at the same time squeezes the reset spring column 1012, and the movable plate 103 synchronously drives the connecting rod 104 and the driving rack 107 to move, so that the driving rack 107 can be in contact with the paired driven toothed disc 2022. In the meshing state, the telescopic guide column 105 cannot complete the extension and retraction. Continuing to push the movable ring 101 will cause the movable ring 101 to push the telescopic guide column 105 and the fixed ring 102 for overall movement, and then the movable sleeve 1 can be driven through the fixed ring 102 to move in the length direction of the fixed sleeve 2, and at the same time drive the driving rack 107 to move, so that the driving rack 107 drives the driven gear plate 2022 to rotate, and the driven gear plate 2022 drives the driven rod 2021 and the wiring wheel 2023 to rotate, and the wiring wheel 2023 can assist in the wiring and threading operation. In this solution, the pushing operation of multiple wire harnesses can be realized simultaneously, reducing the difficulty of wiring in the machine room and improving the efficiency of wiring in the machine room.

[0025] After the movable sleeve 1 completes a stroke, the movable ring 101 is pulled back, so that the movable wedge 1031 and the fixed wedge 1061 slide in the opposite direction and contact, and at the same time, the reset spring column 1012 pushes the movable plate 103 in the opposite direction, so that the movable plate 103 drives the connecting rod 104 and the driving rack 107 as a whole, so that the driving rack 107 and the driven gear plate 2022 are out of meshing state. When the telescopic guide column 105 cannot complete the telescopic extension, the movable ring 101 drives the telescopic guide column 105, the fixed ring 102 and the movable sleeve 1 to move in the opposite direction to the initial position. Since the driving rack 107 and the driven gear plate 2022 are out of meshing state, the routing wheel 2023 will not be driven to rotate in the opposite direction when the driving rack 107 moves in the opposite direction, and the pushed cable will not be pulled back. Example

[0026] This embodiment is based on the first embodiment, which adds a method of winding the multiple wire harnesses into a single wire harness while threading them, so as to avoid the phenomenon of wire harness stacking and blocking caused by the advancement of the multiple wire harnesses. It can also reduce the difficulty of threading the multiple wire harnesses and improve the threading efficiency. Figure 1-Figure 3 and Figure 8 The specific structure is as follows: a winding gear ring 201 is rotatably installed at the front end of the fixed sleeve 2, and the winding gear ring 201 is provided with a plurality of wiring holes 2011 in a ring array and penetrating in the thickness direction; a driving mechanism for driving the winding gear ring 201 to rotate is installed on the outer wall of the fixed sleeve 2, and the driving mechanism includes a reciprocating screw 401 fixedly installed on the side of the fixed ring 102 away from the movable ring 101 and a bracket 508 fixedly installed on the outer wall of the fixed sleeve 2, the bracket 508 is arranged near the front end of the fixed sleeve 2, a half gear disk 402 is rotatably installed on the bracket 508, the half gear disk 402 is intermittently meshed with the winding gear ring 201 for transmission, and the reciprocating screw 401 penetrates the half gear disk 402 and the bracket 508, and the reciprocating screw 401 is threadedly connected to the half gear disk 402.

[0027] The specific implementation method of winding multiple wire harnesses into a single wire harness during the synchronous threading of multiple wire harnesses in this embodiment is as follows: The wiring harness routed through the wiring wheel 2023 passes through the wiring hole 2011 on the winding gear ring 201 at the front end of the fixed sleeve 2, and pushes the reciprocating screw rod 401 through the fixed ring 102, so that the reciprocating screw rod 401 can drive the half gear plate 402 to rotate, and the half gear plate 402 is then meshed with the winding gear ring 201 for transmission, driving the winding gear ring 201 to rotate, so that the winding gear ring 201 can wind multiple strands of cables into a single strand of cable for advancement, avoiding blockage caused by stacking of multiple strands of cables during threading, reducing threading difficulty, and improving threading efficiency.

[0028] By setting the reciprocating screw rod 401, when the reciprocating screw rod 401 moves in the opposite direction as a whole with the fixed ring 102 and the movable sleeve 1, it continues to drive the half gear plate 402 to rotate along the original rotation direction, so that the half gear plate 402 and the winding gear ring 201 are disengaged, and the winding gear ring 201 stops rotating, so that the wire harness that has been wound into a single strand will not be untied. Example

[0029] This embodiment is based on the first and second embodiments, and a protective layer is added to the surface of the cable to prevent the cable skin from being damaged during the threading process, which affects the subsequent normal use of the cable. Figure 1-Figure 3, the specific structure is as follows: On the side of the winding tooth ring 201 away from the fixed sleeve 2, a driving bevel gear ring 502 is fixedly connected. On the outer wall of the fixed sleeve 2 near the front end, symmetrically distributed stabilizing rods 501 are fixedly connected. The stabilizing rods 501 are arranged in a "C" shape, and the ends of the two stabilizing rods 501 are jointly fixedly connected to a stabilizing ring 509. On the side of the stabilizing ring 509 away from the driving bevel gear ring 502, a driven bevel gear ring 505 is rotatably installed. On the bracket 508, a transmission mechanism is provided that cooperates with the driving bevel gear ring 502 and the driven bevel gear ring 505. The transmission mechanism includes a mounting frame 503 fixedly installed at the top of the bracket 508. The mounting frame 503 is arranged in a "J" shape, and the mounting frame 503 bypasses the semi-gear disk 402. And the bottom end of the mounting frame 503 is rotatably connected to a transmission bevel gear 504 that meshes with the driving bevel gear ring 502 and the driven bevel gear ring 505. A cylindrical hole is opened on the mounting frame 503 for the reciprocating lead screw 401 to move along the length direction of the fixed sleeve 2.

[0030] Referring to Figure 2 , on the side of the driven bevel gear ring 505 away from the driving bevel gear ring 502, a detachable fixing rod 506 is installed, and a film winding roller 507 for winding and protecting the surface of the cable is sleeved on the rod body of the fixing rod 506.

[0031] The specific implementation method for protecting the surface of the single-strand wound wire harness with a protective layer is as follows: During the rotation of the winding tooth ring 201, it can synchronously drive the rotation of the driving bevel gear ring 502. The driving bevel gear ring 502 drives the rotation of the transmission bevel gear 504, and the transmission bevel gear 504 then drives the rotation of the driven bevel gear ring 505. Thus, the driven bevel gear ring 505 can drive the fixing rod 506 and the film winding roller 507 on the fixing rod 506 to rotate, and the rotation direction is opposite to the winding direction of the wire harness. Therefore, when the end of the protective layer wound on the film winding roller 507 is fixed on the surface of the wire harness, the protective layer wound on the film winding roller 507 can be wrapped on the surface of the wire harness through the rotation in the opposite direction, providing surface protection for the wire harness and avoiding damage to the cable skin during the threading process, which may affect the subsequent normal use of the cable.

[0032] Working principle: When using this machine room wire threader, the cables to be threaded are respectively passed through the paired wire wheels 2023, and then the movable ring 101 is pushed, so that the movable ring 101 drives the movable plate 103 to move, and the movable ring 101 shortens the telescopic guide column 105, and at the same time makes the movable wedge block 1031 on the movable plate 103 and the fixed wedge block 1061 on the fixed plate 106 slide in contact, so that the movable wedge block 1031 pushes the movable plate 103 to slide inside the movable groove 1011, and at the same time squeezes the reset spring column 1012, and the movable plate 103 synchronously drives the connecting rod 104 and the driving rack 107 to move, so as to This enables the driving rack 107 to be in meshing state with the paired driven toothed disc 2022. At this time, the telescopic guide column 105 cannot be extended or retracted. Continuing to push the movable ring 101 will cause the movable ring 101 to push the telescopic guide column 105 and the fixed ring 102 to move as a whole, and then the movable sleeve 1 can be driven by the fixed ring 102 to move in the length direction of the fixed sleeve 2, while driving the driving rack 107 to move, so that the driving rack 107 drives the driven toothed disc 2022 to rotate, and the driven toothed disc 2022 drives the driven rod 2021 and the wiring wheel 2023 to rotate, and the wiring wheel 2023 can assist in the wiring and threading operation.

[0033] The wiring harness of the wiring wheel 2023 passes through the wiring hole 2011 on the winding gear ring 201 at the front end of the fixed sleeve 2, and pushes the reciprocating screw rod 401 through the fixed ring 102, so that the reciprocating screw rod 401 can drive the half gear plate 402 to rotate, and the half gear plate 402 is meshed with the winding gear ring 201 for transmission, driving the winding gear ring 201 to rotate, so that the winding gear ring 201 can wind multiple strands of wires into a single strand of cable for advancement, and at the same time, during the rotation of the winding gear ring 201, it can synchronously drive the cone gear ring 502 to rotate. The driving bevel gear ring 502 drives the transmission bevel gear 504 to rotate, and the transmission bevel gear 504 drives the driven bevel gear ring 505 to rotate, so that the driven bevel gear ring 505 can drive the fixed rod 506 and the coating roller 507 on the fixed rod 506 to rotate, and the rotation direction is opposite to the winding direction of the wire harness. Therefore, when the end of the protective layer wound on the coating roller 507 is fixed on the surface of the wire harness, the protective layer wound on the coating roller 507 can be wrapped on the surface of the wire harness by rotating in the opposite direction, so as to provide surface protection for the wire harness.

[0034] After the movable sleeve 1 completes a stroke, the movable ring 101 is pulled back, so that the movable wedge 1031 and the fixed wedge 1061 slide in the opposite direction, and the reset spring column 1012 pushes the movable plate 103 in the opposite direction, so that the movable plate 103 drives the connecting rod 104 and the driving rack 107 as a whole, so that the driving rack 107 and the driven gear plate 2022 are out of meshing state. When the telescopic guide column 105 cannot complete the telescopic movement, the movable ring 101 drives the telescopic guide column 105, the fixed ring 102 and the movable sleeve 1 to move in the opposite direction to the initial position. 07 is out of meshing state with the driven gear disc 2022, so when the driving rack 107 moves in the reverse direction, it will not drive the wiring wheel 2023 to rotate in the reverse direction, thereby not pulling back the pushed cable, and through the setting of the reciprocating screw rod 401, when the reciprocating screw rod 401 moves in the reverse direction as a whole with the fixed ring 102 and the movable sleeve 1, it continues to drive the half gear disc 402 to rotate along the original rotation direction, so that the half gear disc 402 is out of meshing state with the winding gear ring 201, and the winding gear ring 201 stops rotating, thereby not untying the wire harness that has been wound into a single strand.

[0035] The invention can assist in wiring and threading operations. In this scheme, the pushing operation of multiple wire harnesses can be realized simultaneously, and the multiple wires can be wound into a single cable for advancement, avoiding blockage caused by stacking of multiple cables during the threading process, reducing the difficulty of threading, improving the threading efficiency, and wrapping the wire harness for protection during the threading process to avoid damage to the cable surface during the threading process, which would affect the subsequent normal use of the cable.
