Description

Technical Field

[0001] This utility model relates to the field of building cable laying technology, specifically a pre-embedded electrical conduit overlapping connector. Background Technology

[0002] Electrical conduits are pipes pre-installed in walls, floors, or ceilings during building construction for the later installation of electrical wires, cables, water pipes, or other equipment. The purpose of pre-installed conduits is to conceal wiring, maintain the building's aesthetics, and facilitate subsequent electrical equipment installation and maintenance.

[0003] With the increasing number of household appliances, the overlapping of different conduits during the pre-installation of electrical conduits is inevitable, sometimes even involving multiple layers. The spacing between the conduits embedded in the bottom and top reinforcing bars is very small, approximately 30 to 100 mm. When two conduits overlap, the conduit height will exceed 40 mm. Currently, to facilitate reasonable and effective control of the overlapping height, some cross-over guide connectors have appeared on the market. While these connectors can effectively control the overlapping height, they cannot effectively allow for readjustment of the cable position after wiring is completed. This leads to friction between the crossed electrical cables during readjustment, and severe friction can cause insulation layer breakage, thus reducing electrical safety. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-embedded electrical conduit overlapping connector. By utilizing the movable adjustment capabilities of the lower pressure plate and the upper lifting plate, the position of the corresponding cable can be adjusted, thereby achieving the separation of the cross-over overlapping cables. This greatly reduces friction when the cables are readjusted, thus improving electrical safety.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pre-embedded electrical conduit overlapping connector, including an overlapping shell and a cover plate. The cover plate is disposed on the upper part of the overlapping shell. Two lower connecting pipes are symmetrically arranged on the lower middle part of the front and rear side walls of the overlapping shell. Two upper connecting pipes are symmetrically arranged on the upper middle part of the left and right side walls of the overlapping shell. A guide pipe is vertically fixed in the middle of the lower inner side wall of the overlapping shell. A guide rod is sleeved in the guide pipe and can move up and down but cannot rotate within the guide pipe. A pressure plate is fixed on the upper part of the guide rod. The pressure plates are distributed along the left and right direction. An upper lifting plate is sleeved on the outside of the guide pipe and can move up and down along the guide pipe but cannot rotate. The upper lifting plate is distributed along the front and back direction.

[0006] Preferably, the guide rod is a hexagonal prism.

[0007] Furthermore, a spring is fitted on the upper outer side of the guide rod, and the spring is clamped between the guide tube and the lower pressure plate. The extension stroke of the spring is less than the length of the guide rod fitted inside the guide tube. A guide post is provided on one side of the guide tube. One end of an upper pull rope passes through the cover plate and the lower pressure plate from top to bottom and comes out from under the guide post and is fixedly connected to the lower plane of the lower pressure plate.

[0008] Preferably, two guide rails are provided on the outside of the guide tube, and the lifting plate is sleeved on the guide rails.

[0009] Furthermore, one end of the pull rope passes through the cover plate from top to bottom and is fixedly connected to the upper part of the lifting plate.

[0010] Preferably, the inner ends of both the upper and lower connecting pipes are tapered sleeves that are larger inside and smaller outside.

[0011] The beneficial effects of this utility model are:

[0012] 1. Improve space utilization: The design of the pressure plate can effectively increase the vertical space required for cables to pass through without changing the original building structure, thus solving the problem of space waste caused by cable accumulation in traditional solutions.

[0013] 2. Reduce friction between cables. When it is necessary to adjust the position of the cable, the corresponding cable can be adjusted by pulling down the pull rope, which reduces direct friction between the cables, facilitates the adjustment of the cable position, and protects the cable from damage.

[0014] 3. Optimize cable layout: The inner ends of both the upper and lower connecting pipes are tapered sleeves, which facilitates the smooth insertion and exit of cables, ensuring the smooth arrangement of cables in the pre-embedded electrical conduits and improving construction efficiency.

[0015] 4. Enhanced structural stability: The lower pressure plate uses guide rods for movement guidance and positioning, while the upper lifting plate uses guide rails for movement guidance and positioning, thereby ensuring the stability and reliability of the entire device and maintaining good working condition even when the cable is subjected to external force.

[0016] 5. Easy to operate: The cable can be adjusted up and down through a simple mechanical structure, without the need for complicated tools or equipment, which reduces the difficulty of construction and improves work efficiency.

[0017] In summary, this utility model not only solves the problems of cable wiring difficulties and unreasonable space utilization in the existing technology, but also greatly improves the safety and convenience of electrical conduit pre-embedding construction, and plays a positive role in improving the overall performance of building electrical systems.

[0023] The following will describe specific embodiments and appendices. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] This utility model provides a pre-embedded electrical conduit overlapping connector (such as...). Figure 1As shown, the device includes a composite housing 1 and a cover plate 2. In practical applications, the composite housing 1 is a hollow component to facilitate cable passage. Both the composite housing 1 and the cover plate 2 can be made of plastic. The cover plate 2 is located on the upper part of the composite housing 1. In practical applications, the cover plate 2 can be directly snapped onto the upper part of the composite housing 1 using a plug-in method. Two lower connecting pipes 3 are symmetrically arranged on the lower middle part of the front and rear side walls of the composite housing 1. In practical applications, cables can pass directly between the two symmetrically distributed lower connecting pipes 3. To further improve the convenience of cable passage, the two lower connecting pipes 3 located on the same side wall can also be symmetrically distributed left and right. Two upper connecting pipes 4 are symmetrically arranged on the upper middle part of the left and right side walls of the composite housing 1. The upper connecting pipes 3 and lower connecting pipes 4 are distributed vertically on the composite housing 1, which facilitates the crossing and passage of cables within the composite housing 1. In practical applications, cables can pass directly between the two symmetrically distributed upper connecting pipes. To further improve the convenience of cable passage, the two upper connecting pipes 4 located on the same side wall are arranged symmetrically. A guide pipe 11 is vertically fixed in the middle of the lower side wall inside the composite housing 1. A guide rod 51 is sleeved inside the guide pipe 11 and can move up and down but cannot rotate within the guide pipe 11. To prevent the guide pipe 11 and guide rod 51 from obstructing the cable passage, the guide pipe 11 and guide rod 51 are aligned with the gap between the two adjacent lower connecting pipes 3 on the left and right. A pressure plate 5 is fixed on the upper part of the guide rod 51. The pressure plate 5 is distributed along the left and right direction and is aligned with the gap between the two adjacent upper connecting pipes 4 on the left and right. An upper lifting plate 6 is sleeved on the outside of the guide pipe 11 and can move up and down along the guide pipe 11 but cannot rotate. The upper lifting plate 6 is distributed along the front and back direction and is aligned with the gap between the two adjacent lower connecting pipes 3 on the left and right. In practical applications, the downward pressing action of the lower pressure plate 5 can be used to press down the cables passing through the two opposite lower connecting pipes 3, thereby providing more space for the cables passing through the upper connecting pipe 4. At the same time, when it is necessary to adjust the cables already passed through in the overlapping housing 1, the downward pressing action of the lower pressure plate 5 can be used to move the lower cables in the overlapping housing 1 downward, thereby facilitating the separation of the upper and lower distributed cables. The upward lifting action of the upper lifting plate 6 can also be used to lift the cables passing through the two opposite upper connecting pipes 3, thereby providing more space for the cables passing through the lower connecting pipe 3. At the same time, when it is necessary to adjust the cables already passed through in the overlapping housing 1, the upward lifting action of the upper lifting plate 6 can be used to move the upper cables in the overlapping housing 1 upward, thereby facilitating the separation of the upper and lower distributed cables. After the cables are separated, the wear and tear between the cables can be reduced, thereby effectively protecting the cable insulation layer and improving electrical safety.

[0025] Based on the above embodiments, the specific implementation method for the guide rod 51 to move up and down without rotating within the guide tube 11 is as follows: the guide rod 51 is a hexagonal prism, which is fitted inside the hexagonal prism guide groove provided inside the guide tube 11. The rotation limit of the guide rod 51 is achieved by using the hexagonal prism guide groove to limit the rotation of the lower pressure plate 5.

[0026] Based on the above embodiments, the specific implementation of the lower pressure plate 5 for controlling the lower pressure cable is as follows: A spring 7 is sleeved on the upper outer side of the guide rod 51. The spring 7 is clamped between the guide tube 11 and the lower pressure plate 5. By using the pushing action of the spring 7 on the lower pressure plate 5, the lower pressure plate 5 can be made to fit against the bottom of the cover plate 2 in the initial position, so as not to obstruct the initial passage of the cable in the two lower connecting tubes 3. The extension stroke of the spring 7 is less than the length of the guide rod 51 sleeved in the guide tube 11. With the above design, the guide rod 51 is effectively prevented from being pushed out of the guide tube 11 by the spring 7. A guide post 12 is set on one side of the guide tube 11. One end of an upper pull rope 8 passes through the cover plate 2 and the lower pressure plate 5 from top to bottom and comes out from under the guide post 12 and is fixedly connected to the lower plane of the lower pressure plate 5. Specifically, two through holes 21 are provided on the cover plate 2, and the lower end of the upper pull rope 8 passes through the corresponding through hole 21. In practical applications, when the pull rope 8 is pulled upward, the lower pressure plate 5 moves downward. During the downward movement of the lower pressure plate 5, the cable below it is pressed down, thereby adjusting the position of the cable downward. When the pull rope 8 is released, the lower pressure plate 5 returns to its initial position under the push of the spring 7.

[0027] Based on the above embodiments, the specific control method for the upward movement of the lifting plate 6 is as follows: two guide rails 111 are provided on the outside of the guide tube 11, and the lifting plate 6 is sleeved on the guide rails 111. Utilizing the guiding effect of the guide rails 111, the lifting plate 6 can only move up and down and cannot rotate. In the initial state, the lifting plate 6 is attached to the inner upper surface of the stacked housing 1. One end of a pull rope 9 passes through the cover plate 2 from top to bottom and is fixedly connected to the upper part of the lifting plate 6. Specifically, the pull rope 9 passes through the corresponding through hole 21 and is fixedly connected to the upper surface of the lifting plate 6. When the pull rope 9 is pulled up or down, the lifting plate 6 moves upward. During the upward movement of the lifting plate 6, the upward displacement and adjustment of the cable are achieved.

[0028] In practical applications, to facilitate the smooth passage of the cable between two opposing upper connecting pipes 3 or lower connecting pipes 4, the inner ends of both the upper connecting pipe 4 and the lower connecting pipe 3 are made into tapered sleeves, wider at the inside and narrower at the outside. The tapered ends of the upper connecting pipe 4 and the lower connecting pipe 3 are used to guide the movement of the cable.

[0029] A specific implementation process for cable crossing, overlapping, and adjustment using this utility model is as follows: First, the cable passes through the lower connecting pipe 3. After being guided by the aligned tapered end, the cable exits. Then, the upper pull rope 8 is pulled upwards. Under the guidance of the guide post 12, the upper pull rope 8 drives the lower pressure plate 5 to press down on the cable, increasing the space above the cable. Then, the cable passes through the upper connecting pipe 4. When the position of the cable in the lower connecting pipe 3 needs to be adjusted after the cable in the upper connecting pipe 4 has passed through, the lower pull rope 9 is pulled upwards. The lower pull rope 9 drives the upper lifting plate 6 to pull the cable passing through the upper connecting pipe 4 upwards, thereby reducing the squeezing friction between the cable passing through the upper connecting pipe 4 and the cable passing through the lower connecting pipe 3, facilitating the position adjustment of the cable passing through the lower connecting pipe 3.

[0030] In this utility model, "upper", "lower", "front", "back", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.

However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
