Description

Technical Field

[0001] The present invention relates to the technical field of wiring conduits, and in particular to a weak-current wiring conduit. Background Art

[0002] Weak current generally refers to DC circuits or audio, video lines, network lines, and telephone lines. The AC voltage is generally within 36V. Household appliances such as telephones, computers, television signal inputs (cable TV lines), audio equipment (output lines), etc. are all weak current electrical equipment.

[0003] The weak-current wiring conduit is the conduit used to distribute telephone, network, television and other points during integrated wiring. When the weak-current lines are laid, they are usually inserted inside the conduit.

[0004] After the weak current line is inserted into the horizontally placed wiring duct, it will come into contact with the bottom wall of the duct due to the effect of gravity. During long-term use, especially in a high-temperature environment, this contact will cause the heat dissipation efficiency of the line to decrease, and then the outer material of the line will soften, making it easy for the line to adhere to the inner wall of the duct. When the weak current line needs to be replaced, this adhesion will make it difficult or time-consuming to extract the original line. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that after the weak current line is inserted into a horizontally placed wiring duct, due to the effect of gravity, it will come into contact with the bottom wall of the duct. During long-term use, especially in a high-temperature environment, this contact will lead to a decrease in the heat dissipation efficiency of the line, and then soften the outer material of the line, which will cause the line to easily adhere to the inner wall of the duct. When the weak current line needs to be replaced, this adhesion will make it difficult or time-consuming to extract the original line. A weak current wiring duct is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A weak current wiring conduit, comprising a main body pipe, the main body pipe comprising a pipe body, a suspension unit installed in the pipe body, a winding unit installed in the suspension unit, an internal thread engraved on one side of the inner wall of the pipe body, and an external threaded member for driving the winding unit to rotate is installed on one side of the inner wall of the pipe body through the internal thread;

[0008] The suspension unit comprises an upper attachment seat fixed to the top wall of the tube body and a lower attachment seat fixed to the bottom wall of the tube body, the upper attachment seat is clamped with an upper suspension member, and the lower attachment seat is clamped with a lower suspension member;

[0009] The unwinding unit comprises an upper unwinding shaft rotatably connected to the upper attachment seat and a lower unwinding shaft rotatably connected to the lower attachment seat, at least one guide rope is fixed to each of the upper unwinding shaft and the lower unwinding shaft, the other end of the guide rope on the upper unwinding shaft is fixed to the upper suspension member, and the other end of the guide rope on the lower unwinding shaft is fixed to the lower suspension member;

[0010] The external threaded part drives the upper winding shaft and the lower winding shaft to rotate counterclockwise during the clockwise rotation inside the tube body, so that the upper suspended part and the lower suspended part gradually move closer to the space, thereby causing the weak current line passed through the upper suspended part and the lower suspended part to be suspended in the middle of the tube body.

[0011] As a further description of the above technical solution:

[0012] Upper heat dissipation grooves are provided on both sides of the inner wall of the upper suspension part, and lower heat dissipation grooves are provided on both sides of the inner wall of the lower suspension part, and the lower heat dissipation grooves are staggered with the upper heat dissipation grooves.

[0013] As a further description of the above technical solution:

[0014] Closed groove bars are fixed on both sides of the inner walls of the upper attachment seat and the lower attachment seat, the lower heat dissipation slot is the same size as the upper heat dissipation slot, the closed groove bars are adapted to the lower heat dissipation slot and the upper heat dissipation slot, and the closed groove bars are provided with assembly grooves, and a roller used for assisting the threading of weak current lines is rotatably connected in the assembly groove;

[0015] The middle parts of the upper attachment seat and the lower attachment seat are both provided with mounting grooves.

[0016] As a further description of the above technical solution:

[0017] The upper unwinding shaft is rotatably connected to the mounting groove on the upper attachment seat, and the lower unwinding shaft is rotatably connected to the mounting groove on the lower attachment seat. At least one retaining groove is provided on the inner top wall of the mounting groove, and a connecting unit is assembled in the retaining groove.

[0018] As a further description of the above technical solution:

[0019] One end of the upper unwinding shaft and the lower unwinding shaft are both fixed with gears, and the inner wall of the external threaded member is equipped with a gear ring meshing with the gears.

[0020] As a further description of the above technical solution:

[0021] The connecting unit includes a vertical tube fixed in the mounting groove, a spring fixed in the vertical tube, one end of the spring in the vertical tube located in the upper attachment seat is fixed to the upper suspension member, and one end of the spring in the vertical tube located in the lower attachment seat is fixed to the lower suspension member.

[0022] As a further description of the above technical solution:

[0023] Both sides of the upper attachment seat and the lower attachment seat are provided with guide slide grooves, and a wire holder for driving the lower layer weak current line to move is slidably mounted in the guide slide groove.

[0024] As a further description of the above technical solution:

[0025] The wire seat comprises a guide member, and positioning rings are fixed on both sides of the inner wall of the guide member, and a plurality of front limiting members and rear limiting members distributed in a circular array are respectively fixed in the two positioning rings;

[0026] A guide sliding block matched with the guide sliding groove is fixed on one side of the guide member, and the guide member slides in the guide sliding groove through the guide sliding block.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] By setting the suspended unit, external threaded part and winding unit, the efficient threading and suspended fixation of the weak current line in the pipe body are realized. During the threading process, the roller effectively helps the line to move smoothly on the suspended part, which significantly improves the working efficiency. After the threading is completed, it is only necessary to rotate the external threaded part clockwise. The inner movement process drives the gear to rotate through the gear ring, driving the winding shaft to rotate counterclockwise, gradually releasing the restraint on the guide rope. Then, under the action of the rebound force of the compressed spring, the upper suspended part and the lower suspended part are offset, and the weak current line is firmly suspended inside the pipe body, which not only avoids the adhesion problem that may be caused by direct contact between the line and the bottom of the pipe, but also the heat dissipation grooves arranged staggered on the surface greatly improve the heat dissipation performance of the line.

[0029] When the line needs to be replaced, rotate the external threaded part counterclockwise to move it outward and drive the winding and unwinding shaft to rotate clockwise, rewind the guide rope, thereby driving the two suspended parts to separate from each other and restore the initial state. At this time, the weak current line falls naturally and with the assistance of the roller, it can be easily and quickly pulled out of the tube body, realizing convenient and efficient line replacement.

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.

[0047] Embodiment 1, as Figure 1 - Fig.11 As shown, the present invention provides:

[0048] A weak current wiring conduit comprises a main body pipe 10, the main body pipe 10 comprises a pipe body 11, a suspension unit 12 is installed in the pipe body 11, a winding unit 20 is installed in the suspension unit 12, an internal thread 13 is engraved on one side of the inner wall of the pipe body 11, and an external thread member 14 for driving the winding unit 20 to rotate is installed on one side of the inner wall of the pipe body 11 through the internal thread 13;

[0049] Specifically, when the external threaded component 14 is rotated clockwise, the external threaded component 14 moves into the tube body 11 , and when it moves to abut against the attachment seat, the external threaded component 14 is in a tightened state.

[0050] like Figure 3 , Figure 5 , Fig. 9 and Fig.10 As shown, the unwinding unit 20 includes an upper unwinding shaft 21 rotatably connected to the upper attachment seat 121 and a lower unwinding shaft 22 rotatably connected to the lower attachment seat 122. At least one guide rope 23 is fixed to each of the upper unwinding shaft 21 and the lower unwinding shaft 22. In the initial state, the guide rope 23 is wound around the unwinding shaft (as shown in FIG. Figure 3 and Fig.10 ), and when the unwinding shaft rotates counterclockwise, the restraint on the guide rope 23 will be gradually released, and when the unwinding shaft rotates clockwise, the guide rope 23 will be rewound around the surface of the unwinding shaft again, and the other end of the guide rope 23 on the upper unwinding shaft 21 is fixed to the upper suspended member 123, and the other end of the guide rope 23 on the lower unwinding shaft 22 is fixed to the lower suspended member 124. During the clockwise rotation of the external threaded member 14 into the tube body 11, the upper unwinding shaft 21 and the lower unwinding shaft 22 are driven to rotate counterclockwise, so that the upper suspended member 123 and the lower suspended member 124 gradually move closer to the space, thereby causing the weak current line passed through the upper suspended member 123 and the lower suspended member 124 to be suspended in the middle of the tube body 11;

[0051] A gear 26 is fixed to one end of the upper unwinding shaft 21 and the lower unwinding shaft 22 , and a gear ring 27 meshing with the gear 26 is mounted on the inner wall of the external threaded member 14 .

[0052] like Figure 3 , Figure 8 , Fig. 9and Fig.10 As shown, a mounting groove 24 is provided in the middle of the upper attachment seat 121 and the lower attachment seat 122;

[0053] The upper unwinding shaft 21 is rotatably connected to the mounting groove 24 on the upper attachment seat 121, and the lower unwinding shaft 22 is rotatably connected to the mounting groove 24 on the lower attachment seat 122. At least one retaining groove 25 is provided on the inner top wall of the mounting groove 24, and a connecting unit 30 is assembled in the retaining groove 25;

[0054] The connecting unit 30 includes a vertical tube 31 fixed in the mounting groove 24, a spring 32 is fixed in the vertical tube 31, one end of the spring 32 in the vertical tube 31 located in the upper attachment seat 121 is fixed to the upper suspension member 123, and one end of the spring 32 in the vertical tube 31 located in the lower attachment seat 122 is fixed to the lower suspension member 124. In the initial state, the spring 32 is in a compressed state (such as Fig.10 );

[0055] Specifically, when the external threaded member 14 rotates clockwise, the toothed ring 27 on the inner wall of the external threaded member 14 can drive the gear 26 to rotate counterclockwise. At this time, the upper winding shaft 21 and the lower winding shaft 22 rotate counterclockwise along with the gear 26, and the guide rope 23 is gradually relaxed during the rotation. At this time, the spring 32 is driven to reset under the action of the elastic force of the spring 32 in the compressed state, and the upper suspended member 123 and the lower suspended member 124 are driven to approach each other, thereby adjusting the weak current line to a state of being suspended in the middle of the tube body 11;

[0056] When it is necessary to change the line, rotate the external threaded part 14 counterclockwise to move it outward, and at the same time drive the gear 26 to rotate clockwise through the gear ring 27, so that the upper winding shaft 21 and the lower winding shaft 22 rotate clockwise, and the guide rope 23 is rewound around the shaft surface again during the rotation. The winding and rewinding process gradually pulls the upper suspended part 123 upward to reset it to fit with the upper attachment seat 121, and at the same time, the lower suspended part 124 is reset downward to fit with the lower attachment seat 122. At this time, the weak current line moves downward following the reset of the lower suspended part 124. After the reset, the weak current line contacts the roller 128, and the spring 32 returns to the compressed state.

[0057] like Figure 2 , Figure 3 , Figure 6 , Figure 8 and Fig. 9 As shown, the suspension unit 12 includes an upper attachment seat 121 fixed to the inner top wall of the tube body 11 and a lower attachment seat 122 fixed to the inner bottom wall of the tube body 11, an upper suspension member 123 is clamped on the upper attachment seat 121, and a lower suspension member 124 is clamped on the lower attachment seat 122;

[0058] Upper heat dissipation slots 125 are provided on both sides of the inner wall of the upper suspension member 123, and lower heat dissipation slots 126 are provided on both sides of the inner wall of the lower suspension member 124, and the lower heat dissipation slots 126 and the upper heat dissipation slots 125 are staggered with each other;

[0059] Closed groove bars 127 are fixed on both sides of the inner wall of the upper attachment seat 121 and the lower attachment seat 122. The lower heat dissipation groove 126 has the same size as the upper heat dissipation groove 125. The closed groove bars 127 are adapted to the lower heat dissipation groove 126 and the upper heat dissipation groove 125. The closed groove bars 127 are provided with an assembly groove, and a roller 128 for assisting the threading of the weak current line is rotatably connected in the assembly groove.

[0060] Specifically, when the suspended member 123 and the lower suspended member 124 on the weak current line are suspended in the tube body 11, the position of the weak current line in the space formed by the upper suspended member 123 and the lower suspended member 124 is as follows: Fig. 9 As shown, in this state, the heat dissipation effect is better.

[0061] Embodiment 2, as Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.11 As shown, both sides of the upper attachment seat 121 and the lower attachment seat 122 are provided with guide slots 129, and a wire holder 40 for driving the lower layer weak current line to move is slidably mounted in the guide slots 129;

[0062] The wire seat 40 includes a guide member 41, and positioning rings 42 are fixed on both sides of the inner wall of the guide member 41. A plurality of front limiting members 43 and rear limiting members 44 distributed in a circular array are fixed in the two positioning rings 42 respectively. A guide slider adapted to the guide slot 129 is fixed on one side of the guide member 41, and the guide member 41 slides in the guide slot 129 through the guide slider.

[0063] After the thicker weak-current line is inserted into the tube body 11 and is suspended in the tube body 11 by the upper suspension member 123 and the lower suspension member 124, when it is necessary to insert a thinner weak-current line into the tube body 11, one end of the thinner weak-current line is inserted into the guide member 41, and the front limiting member 43 and the rear limiting member 44 fix the inserted weak-current line in the guide member 41, and then the guide member 41 is slid into the guide groove 129 on the lower attachment seat 122 through the guide slider, and then the wire is fed into the tube body 11, so that the guide member 41 drives the weak-current line to slide in the tube body 11, and at this time, the roller 128 can make the guide member 41 slide more easily, and at the same time, after the threading is completed, the weak-current line is overlapped on the closed-slot ribs 127 arranged at intervals, so that the weak-current line can also have a good heat dissipation effect.

[0064] Specifically, when the weak current wiring conduit is working / in use:

[0065] First, the weak current line to be passed through the tube body 11, and the threading operation is completed quickly under the action of the roller 128. After completion, the external threaded member 14 is rotated clockwise, and the toothed ring 27 on the inner wall of the external threaded member 14 drives the gear 26 to rotate counterclockwise. At this time, the upper winding shaft 21 and the lower winding shaft 22 rotate counterclockwise with the gear 26, and the guide rope 23 is gradually relaxed during the rotation. At this time, the spring 32 is driven to reset under the action of the elastic force of the spring 32 in the compressed state, and the upper suspended member 123 and the lower suspended member 124 are driven to approach each other, so that the weak current line is adjusted to a state of being suspended in the middle of the tube body 11;

[0066] When it is necessary to change the line, the external threaded member 14 is rotated counterclockwise to move it outward, and the gear 26 is driven to rotate clockwise through the gear ring 27, so that the upper winding shaft 21 and the lower winding shaft 22 rotate clockwise. During the rotation process, the guide rope 23 is rewound and wound on the shaft surface again. The winding and winding process gradually pulls the upper suspended member 123 upward to reset to fit with the upper attachment seat 121, and the lower suspended member 124 is reset downward to fit with the lower attachment seat 122. At this time, the weak current line moves downward following the reset of the lower suspended member 124. After the reset, the weak current line contacts the roller 128, and the spring 32 is restored to the compressed state. At this time, the weak current line naturally falls following the reset of the lower suspended member 124. At this time, with the assistance of the roller 128, the weak current line can be quickly pulled out of the tube body 11;

[0067] After the line is threaded and the line is suspended, if it is necessary to continue to insert a thinner weak-current line, one end of the thinner weak-current line is inserted into the guide member 41, and the front limiting member 43 and the rear limiting member 44 fix the inserted weak-current line in the guide member 41, and then the guide member 41 is slid into the guide groove 129 on the lower attachment seat 122 through the guide slider, and then the line is fed into the tube body 11, so that the guide member 41 drives the weak-current line to slide in the tube body 11. At this time, the roller 128 can make the guide member 41 slide more easily. At the same time, after the threading is completed, the weak-current line is overlapped on the closed-groove strips 127 set at intervals. When changing the line, the thinner weak-current line must be replaced first. During the replacement, the guide member 41 can slide out quickly with the line with the assistance of the roller 128, and then the above-mentioned line changing operation is performed, and the replacement operation of the thinner weak-current line and the thicker weak-current line can be completed.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
