Description

Technical Field

[0001] The present invention relates to the technical field of cable wiring, and more particularly, to a cable pre-buried wiring device for building electrical construction. Background Art

[0002] The cable pre-buried wiring in building electrical construction is an important part of the electrical installation project, which refers to the process of pre-laying electrical wires and cables inside the structures such as the walls, floors or ceilings of buildings. This process usually occurs during the building construction stage, when the walls and floors are not yet enclosed, and its main purpose is to ensure the safety, concealment and aesthetics of the electrical lines inside the building.

[0003] Currently, on the actual construction site, the cable pre-buried wiring operation is mostly completed by simple methods. Specifically, after the steel bars are tied, workers directly use plastic pipes and their connectors, and fix these pipes at the predetermined positions through iron wires to achieve the purpose of pre-arrangement. Although it meets the basic wiring requirements to a certain extent, there are the following implementation problems with this operation method:

[0004] First of all, the intersection of cables during the wiring process may lead to a series of negative effects. Especially when strong and weak electric wires (such as power lines and signal lines) intersect, if not properly handled, the electromagnetic field generated by the strong electric wire may cause electromagnetic interference to the weak electric wire, thereby affecting the signal transmission quality and resulting in signal degradation or communication failure.

[0005] Secondly, during the laying process, it is necessary to frequently adjust and bend the pipes. The existing method relies on manual bending and fixing with iron wires, which is particularly inconvenient when facing the simultaneous adjustment of multiple pipes. Workers need to spend a lot of time and energy on precise adjustment, and it is difficult to ensure the consistency of the bending angles and positions of the pipes everywhere. This not only increases the labor intensity of the workers, but also may affect the project quality due to inaccurate operation.

[0006] In view of the existence of the above problems, it is particularly necessary to develop a cable pre-buried wiring device for building electrical construction, aiming to solve the technical problems encountered in the traditional wiring process and improve the wiring efficiency and quality. Summary of the Invention

[0007] In order to overcome the above-mentioned disadvantages existing in the prior art, the present invention provides a cable pre-buried wiring device for building electrical construction, including:

[0008] A cable embedding box, which is a box body with openings on four sides. There is a pillar with an internal cavity respectively arranged on each of the four sides inside the cable embedding box. A cover plate is provided on the cable embedding box. There is an insertion rod that is inserted and matched with the adjacent pillar respectively arranged at the four weeks of the bottom of the cover plate, and a first rack is arranged on each of the insertion rods;

[0009] The intubation frames, four in number, are arranged at each opening of the buried wire box;

[0010] The support rods are arranged in the cavities of each support column. At both sides of the top end of the support rod, coaxial connected full gears are rotatably arranged. The full gears are meshed with the first rack in the same cavity. In each cavity, a group of triangular frames arranged at intervals are also slidably arranged. An elastic member II is arranged between one end of the triangular frame and the inner wall of the cavity. And a second rack meshed with the adjacent full gear is arranged in the triangular frame. The adjacent second racks are arranged oppositely. A push rod slidably matched with the buried wire box is arranged between the two triangular frames on the same side;

[0011] The wire bundling frames are distributed around the buried wire box and sleeved on the buried pipes on each side. A first bottom plate slides at the bottom of the wire bundling frame. A hinge plate is arranged on the first bottom plate. A rotating seat is hingedly arranged on the hinge plate. A second bottom plate is arranged on the rotating seat. A wire bundling frame also slides on the top of the second bottom plate.

[0012] Further, a fastening assembly is also arranged at each opening of the buried wire box. The fastening assembly includes fitting frames arranged at intervals at each opening of the buried wire box. The number of fitting frames at each opening is at least two. A group of clamping rods spaced up and down are slidably inserted in the fitting frame. The end of the clamping rod is located outside the fitting frame. And an elastic member I is arranged between the same group of clamping rods. Corresponding clamping grooves for clamping and cooperating with the clamping rods are arranged on the upper and lower inner walls of the intubation frame.

[0013] Further, a rotating rod is rotatably inserted between the two sides of each wire bundling frame. Holding ends are arranged at both ends of the rotating rod. A group of worms arranged at intervals are arranged on the rotating rod. A turntable adapted to the layout of the worms is also rotatably arranged in the wire bundling frame. Worm wheels meshed with the adjacent worms are arranged at the rotating ends of the turntable. Fitting rods for tightening the buried pipes are also arranged on the two turntables on both sides.

[0014] Further, a retaining frame is arranged on the upper side of the periphery of the buried wire box. A concave along-channel is opened at the top of the retaining frame.

[0015] Further, a group of jacks are respectively opened at the four weeks of the top of the retaining frame. Vertical plates are inserted in the jacks. A baffle is arranged between the two vertical plates on the same side through fixing nails, so that the baffle is arranged in a four-week layout.

[0016] Further, a positioning rod slides on the hinge plate. A groove adapted to the insertion and cooperation of the positioning rod is opened circumferentially on the rotating seat.

[0017] Further, fastening rods slidably inserted and cooperated with the respective support columns of the buried wire box are arranged at the four weeks of the cover plate.

[0018] Further, the two oppositely arranged push rods are in the same state, while the two adjacent push rods are in opposite states.

[0019] On the basis of overcoming the shortcomings of the prior art, the beneficial effects that the present invention can achieve are as follows:

[0020] 1. The present invention adopts a push rod design. Combining the synergistic effects of rack one, full gear, and rack two, it realizes the precise movement of each push rod, utilizes the morphological characteristics of the push rod to jack up or press down the embedded pipes at corresponding positions, effectively avoids the intersection problem during cable laying, reduces electromagnetic interference, and ensures the quality of signal transmission. At the same time, through the cooperation of the wire bundling frame with the hinge plate and the rotating seat, it realizes the flexible adjustment of the position of the wire bundling frame to adapt to the bending state of the embedded pipes, not only improves the operation convenience, but also ensures the stability and reliability of the device.

[0021] 2. The design of the clamping rod and the insertion pipe frame in the present invention adopts a clamping connection method, which not only ensures the overall stability of the structure, but also realizes the detachable function, supports the adaptation adjustment of the number of pipes according to actual needs, and makes the whole device more flexible and convenient for disassembly and assembly.

[0022] 3. The present invention introduces a fitting rod design. By the meshing action of the worm and the worm gear to drive the turntable, the fitting rod can effectively apply pressure to the embedded pipe, ensure the tightness and stability after cable laying, and improve the construction laying quality.

[0023] 4. The present invention is provided with a retaining frame, a vertical plate, and a baffle, which can effectively protect the cable embedding box from the possible splashing and covering during the cement pouring process before cable laying, and ensure the smooth progress of the wiring work.

[0037] In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The technical solutions of the present invention will be clearly and completely described below with reference to the drawings. It should be noted that the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Embodiment 1: A cable embedded wiring device for building electrical construction, as Figures 1-9As shown in the figure, it includes: a buried wire box 1, which is a box structure with a hollow interior and four open sides. Pillars with built-in cavities are respectively arranged on the four sides inside the buried wire box 1. The pillars are designed as upright cylinders, and their tops are flush with the upper edge of the buried wire box 1. A cover plate 11 is provided at the box opening at the top of the buried wire box 1 to seal the buried wire box 1. Plug rods 12 that are respectively inserted into the cavities of adjacent pillars are arranged around the bottom of the cover plate 11, so that the cover plate 11 can be stably installed with the buried wire box 1, effectively improving the sealing performance of the overall device. At the same time, the plug-in connection method makes the disassembly and assembly of the cover plate 11 simple and fast, greatly improving the work efficiency of on-site construction. And racks 14 are arranged on the plug rods 12;

[0039] Four intubation frames 2 are provided, which are arranged on each opening of the buried wire box 1. A number of pipe ends are equipped on the intubation frames 2 for inserting the embedded pipes 100, thereby providing a necessary channel for subsequent cable layout; at the same time, considering cost-effectiveness, the intubation frames 2 can be made of low-cost materials such as plastics and support customized design and replacement, so as to effectively control the construction cost and improve the overall practicability and flexibility of the device;

[0040] Support rods 3 are arranged in the cavities of each pillar. The support rods 3 are located at the middle position of the bottom of each cavity, and the support rods 3 are designed as vertical rods. Coaxially connected full gears 31 are rotated on both sides of the top of the support rods 3 to ensure the synchronous rotation of the full gears 31 on both sides. And the full gears 31 are engaged with the racks 14 in the same cavity. When the cover plate 11 and the plug rods 12 are inserted into the corresponding cavities, the racks 14 will be engaged with the full gears 31 on the corresponding support rods 3, providing the necessary driving force for subsequent operations. A group of triangular frames 32 arranged at intervals are also slid in each cavity. The triangular frames 32 in the same group are respectively located on one side of the corresponding support rod 3. An elastic member 34 is arranged between one end of the triangular frame 32 and the inner wall of the cavity. In this embodiment, the elastic member 34 is a spring, providing the necessary elastic force for the reset movement of the triangular frame 32. And racks 33 that are engaged with the adjacent full gears 31 are arranged in the triangular frame 32. The two adjacent racks 33 in the same group are arranged oppositely to adapt to the operation mechanism of the corresponding full gears 31, ensuring that the two triangular frames 32 in the same group can move relatively. And a push rod 35 that is slidably engaged with the buried wire box 1 is fixedly arranged between the two triangular frames 32 on the same side, so that a push rod 35 is arranged on the inner walls around the buried wire box 1 respectively. The two oppositely arranged push rods 35 have the same shape, while the two adjacent push rods 35 have opposite shapes, ensuring that the embedded pipes 100 in different directions can be arranged orderly inside the buried wire box 1, thereby forming two different configurations of the push rods 35 (see Figure 6); Specifically, the push rod 35 in the front-back direction is set in an upward state, while the push rods 35 on the left and right sides are set in a downward state. This layout allows the push rod 35 to effectively lift or press down the arranged embedded pipes 100 at the corresponding positions. In particular, the embedded pipes 100 are mostly made of a ductile material, which enables the embedded pipes 100 to deform to a certain extent during the pushing operation of the push rod 35, thereby adaptively adjusting the spacing, avoiding unnecessary crossing and contact, optimizing the wiring effect of the cables, and ensuring the safety and stability of the use of various lines.

[0041] The wire bundling frame 4 is distributed around the wire embedding box 1 and sleeved on each side of the embedded pipe 100, and is used to provide an orderly and compact cable layout management. A bottom plate 41 slides on the bottom of the wire bundling frame 4. An articulated plate 42 is provided on the bottom plate 41. A rotating seat 44 is articulated on the articulated plate 42. A bottom plate 45 is provided on the rotating seat 44. Another wire bundling frame 4 also slides on the top of the bottom plate 45. Through the settings of the bottom plate 41 and the bottom plate 45, a stable supporting carrier is provided for each wire bundling frame 4. By pushing the wire bundling frame 4 to slide along the corresponding bottom plate 41 or bottom plate 45, the bending limit range of the embedded pipe 100 can be adjusted. Combining with the rotation adjustment function of the articulated plate 42 and the rotating seat 44, the positions and angles of each component can be flexibly adjusted according to the actual routing requirements, adapting to various complex wiring environments, and significantly enhancing the adaptability and flexibility of the device.

[0042] As Figure 2 and Figure 3 shown, it also includes a fastening component arranged on each opening of the wire embedding box 1. The fastening component includes fitting frames 22 arranged at intervals on each opening of the wire embedding box 1. The number of fitting frames 22 on each opening is two. A group of vertically spaced clamping rods 23 are slidably penetrated in the fitting frames 22. The ends of the clamping rods 23 are located outside the fitting frames 22, and an elastic member 24 is arranged between the same group of clamping rods 23. In this embodiment, the elastic member 24 is a spring, which provides the necessary elastic force. Corresponding clamping grooves 21 for clamping and cooperating with the clamping rods 23 are arranged on the upper and lower inner walls of the insertion pipe frame 2.

[0043] When in use, the pipe inserting frame 2 of the required specifications is customized according to the wiring needs, and then the buried wire box 1 is installed in the required area, and then the operation can be carried out. First, the end of the clamping rod 23 on one side is pinched to make the two connected parts close together, and the elastic member 24 is deformed accordingly, and then the required pipe inserting frame 2 is inserted into the embedded frame 22 until the end face of the pipe inserting frame 2 fits with the buried wire box 1, and then the clamping rod 23 is loosened, the elastic member 24 is reset, and the clamping rod 23 automatically passes through the embedded frame 22 and is inserted into the corresponding clamping groove 21, so as to fix the position of the pipe inserting frame 2, repeat the above steps, complete the assembly work of the pipe inserting frame 2 at each opening of the buried wire box 1, and then start laying the buried pipe 100, connect the corresponding buried pipe 100 between the two opposite pipe inserting frames 2, and gather them in the buried wire box 1 to form the wiring layout of the cable;

[0044] Then, the wire harness frame 4 is sleeved on the embedded tube 100 on each side, and the wire harness frame 4 is pushed to slide so as to adjust its position along the bottom plate 1 41 or the bottom plate 2 45, and then the overall structure of the embedded tube 100 is tilted and bent to drive the hinge plate 42 and the rotating seat 44 to rotate, thereby adjusting the bending degree of the embedded tube 100 to ensure that a stable channel is provided for subsequent cable wiring. Then you can pour cement. Before pouring cement, check the embedded pipe 100 to ensure that there is no damage or blockage, and use temporary plugging materials to seal the two ends of the embedded pipe 100 to prevent debris from entering. Then start pouring cement. During this process, you need to be careful to avoid pouring into the interior of the buried cable box 1, and ensure that the laid embedded pipe 100 is not damaged; after the cement is completely solidified, the cable is arranged; after the cable arrangement is completed, the buried cable box 1 can be capped, the cover plate 11 is covered at the box opening of the buried cable box 1, and the surrounding plug rods 12 are inserted into the cavity of the corresponding pillar, and the rack 14 is meshed with the corresponding full gear 31, thereby driving the full gears on both sides. 31 rotates synchronously, so that the full gear 31 is synchronously meshed with the adjacent rack 2 33 to drive the connected triangular frame 32 to slide along the cavity. Since the two adjacent racks 2 33 are relatively arranged, the adjacent triangular frames 32 move relatively, and the elastic member 2 34 deforms accordingly, driving the corresponding push rods 35 to move along the buried wire box 1, and then the relative push rods 35 move in the same direction, and the adjacent push rods 35 move in the opposite direction, thereby performing corresponding lifting or pressing operations on the pipeline inside the buried wire box 1, so as to adjust the cable layout, ensure the spacing between the pipelines, avoid unnecessary intersections, and protect the safety of cable use.

[0045] Embodiment 2: Based on embodiment 1, Figure 9 and Figure 10As shown, it further includes a rotating rod 46 rotatably passing through between the two sides of each wire bundling frame 4. Both ends of the rotating rod 46 are provided with a holding end 461 for easy operation. A group of worm gears 462 arranged at intervals are provided on the rotating rod 46. A turntable 464 adapted to the layout of the worm gears 462 is also rotatably provided in the wire bundling frame 4. The rotating ends of the turntable 464 are respectively provided with worm wheels 463 meshing with the adjacent worm gears 462. A fitting rod 465 for tightening the embedded pipe 100 is also provided on both sides of the turntable 464.

[0046] When arranging the embedded pipe 100, hold the holding end 461 to drive the rotation of the rotating rod 46, thereby driving the corresponding worm gear 462 to rotate and mesh with the adjacent worm wheel 463, so as to drive the rotation of the turntables 464 on both sides, drive the relatively moving of the fitting rods 465 connected on both sides, and gradually contact and push together the embedded pipes 100, thereby tightly restricting the interval position between the embedded pipes 100 to ensure the consistency of the layout. At the same time, the worm gear 462 and the worm wheel 463 have a self-locking function, so as to effectively stabilize the arrangement position of the embedded pipe 100.

[0047] As Figure 1 and Figure 11 shown, a retaining frame 5 is provided on the upper side of the periphery of the buried wire box 1. An inward concave circumferential channel is opened at the top of the retaining frame 5. The design of the retaining frame 5 provides an additional physical protection layer for the buried wire box 1, which can effectively prevent cement from invading the inside of the buried wire box 1 during the pouring of cement; at the same time, the setting of the channel also provides the necessary space and support for the subsequent operation of strengthening the protection layer.

[0048] As Figure 11 shown, a group of jacks 51 are respectively opened at the four circumferential sides of the top of the retaining frame 5. The number of a group of jacks 51 is two. The same group of jacks 51 respectively face one side of the retaining frame 5. Vertical plates 52 are inserted into the jacks 51. A baffle 53 is provided between the two vertical plates 52 on the same side through fixing nails 54, so that the baffle 53 forms a surrounding shielding structure. Specifically, before pouring cement, it is necessary to insert the vertical plates 52 into the respective jacks 51 of the retaining frame 5, and then assemble a baffle 53 between the vertical plates 52 on the same side through fixing nails 54, so as to extend the height of the four circumferential sides of the periphery of the retaining frame 5 to further prevent the invasion of cement during the pouring process; and considering the construction environment factors, the vertical plates 52 and the baffle 53 can both be made of waste wooden boards on site to meet the requirements of cost-effectiveness.

[0049] As Figure 8 and Figure 9 shown, a positioning rod 43 slides on the hinge plate 42. A groove inserted and matched with the positioning rod 43 is opened circumferentially on the rotating seat 44, allowing the positioning rod 43 to be inserted into different grooves on the rotating seat 44 as needed to fix the bent position after adjustment.

[0050] As Figures 2-4As shown in the figure, buckle rods 13 that are slidably inserted through the four peripheral positions of the cover plate 11 and are inserted and matched with the respective columns of the buried wire box 1 are provided to ensure that the cover plate 11 can be firmly fixed on the buried wire box 1.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
