Description

Technical Field

[0001] This utility model relates to a wiring device for electrical equipment installation, belonging to the field of electrical equipment installation. Background Technology

[0002] Before installing electrical equipment, wiring plans must be developed based on equipment layout, usage requirements, and building structure. Simultaneously, the installation location of the cable trays should be determined in conjunction with the building's wall and ceiling structures to ensure neat and orderly wiring for easy future inspection and maintenance. When cable tray space is limited, multiple wires often need to be laid within the tray. During the wire insertion process, multiple wires are typically inserted from one end of the cable tray, and then each wire exits one by one through a channel on the side of the tray, thus achieving the predetermined path along the cable tray. However, when there are many wires in the cable tray, the problem of wires crimping together arises. If a wire is damaged and needs replacement later, due to the numerous crimped wires, pulling out the damaged wire will encounter significant resistance, not only wasting a lot of time and increasing labor costs, but also creating numerous difficulties for maintenance work. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wiring device for electrical equipment installation to solve the problems mentioned in the background art. This utility model allows multiple wires to be laid in layers in the wire trough, reducing the resistance when pulling out damaged wires in the wire trough later.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wiring device for electrical equipment installation, comprising a wire trough with a U-shaped cross-section. Multiple evenly arranged dividing strips are installed on the upper parts of the two parallel sides of the wire trough. A gap for threading wires exists between adjacent dividing strips. A top cover is inserted into the end of each dividing strip away from the wire trough. A base plate is inserted into the side of the wire trough away from the top cover. Multiple layers of parallel strips are provided on the upper surface of the base plate. Two through holes are formed on the upper surface of each strip. A guide rod is inserted into each through hole, with one end connected to the base plate. A support sleeve is provided on the upper side of each through hole, concentrically arranged with the through hole. One end of the support sleeve is connected and fixed to the layered strips. A rubber sleeve is glued inside the support sleeve, and the rubber sleeve wraps around the guide rod.

[0005] Furthermore, the upper surface of the base plate is evenly provided with a plurality of first fixing holes for inserting screws, and the side of the wire groove facing the base plate is evenly provided with a plurality of second fixing holes, with the first fixing holes and the second fixing holes aligned.

[0006] Furthermore, the outer surface of the guide rod near the base plate is machined with external threads, and the end of the guide rod with the external threads is threadedly connected to an internal thread sleeve, which is fixedly connected to the base plate.

[0007] Furthermore, the area where the internal threaded sleeve is installed on the base plate is recessed to form a blind hole, and one end of the internal threaded sleeve is glued into the blind hole.

[0008] Furthermore, the separator strip and the groove are integrally formed, and the bottom of the separator strip and the groove are arranged perpendicular to each other.

[0009] Furthermore, each of the two parallel sides of the separator is provided with a protrusion, which is integrally formed with the separator, and there is a gap between the protrusion on one separator and the protrusion on the other separator.

[0010] Furthermore, a slot is fixed to one end of the separator away from the groove, and a plug is installed on the lower part of the two parallel sides of the top cover, with the plug inserted into the slot.

[0011] Furthermore, the slot portion has a "V" shaped cross-section, and the insertion portion has a "V" shaped cross-section.

[0012] Furthermore, the slot portion and the partition strip are integrally formed, and the insertion portion and the top cover are integrally formed.

[0013] Furthermore, a plurality of first annular protrusions are evenly installed on the guide rod, and a plurality of second annular protrusions are evenly installed on the inner surface of the rubber sleeve.

[0014] The beneficial effects of this utility model are:

[0015] 1. The cable tray is equipped with multiple layers of strips, along with guide rods, support sleeves, and rubber sleeves, allowing multiple wires to be laid out in layers. Compared to the traditional method where wires are crimped together in cable trays, this layered method effectively reduces the resistance when pulling out damaged wires later, reducing maintenance time and labor costs.

[0016] 2. The adjustable position of the layered strips on the guide rod allows for flexible adjustment of the strip spacing based on the wire distribution requirements in practical applications. Specifically, the spacing of the strips can be reduced on the side where the wires enter the cable tray, making the wire insertion more compact and orderly; while the spacing can be increased in areas away from the wire entry side, providing more space for the wires to extend. This not only optimizes the space utilization within the cable tray but also effectively reduces mutual compression and tangling between wires, ensuring the neatness and rationality of the wiring within the cable tray.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1 , Figure 4 and Figure 5This utility model provides a technical solution: a wiring device for electrical equipment installation, including a cable tray 1 with a U-shaped cross-section. Multiple evenly arranged partition strips 2 are installed on the upper parts of the two parallel sides of the cable tray 1. The partition strips 2 are integrally formed with the cable tray 1, and are arranged perpendicularly to the bottom of the cable tray 1. A gap for threading wires exists between adjacent partition strips 2. A protrusion 13 is installed on each of the two parallel sides of the partition strip 2, and the protrusion 13 is integrally formed with the partition strip 2. A gap exists between the protrusion 13 on one partition strip 2 and the protrusion 13 on another partition strip 2. In the gap, a top cover 4 is inserted into the end of the separator 2 away from the wire trough 1. A slot 14 with a "V"-shaped cross-section is fixedly connected to the end of the separator 2 away from the wire trough 1. The slot 14 and the separator 2 are integrally formed. Two parallel sides of the top cover 4 each have a "V"-shaped insertion part 15 installed at their lower positions. The insertion part 15 and the top cover 4 are integrally formed, allowing the insertion part 15 to be inserted into the slot 14, completing the connection between the separator 2 and the top cover 4. The separators 2 on the sides of the wire trough 1 are evenly distributed, and the gaps between adjacent separators 2 are used for threading wires, ensuring orderly arrangement and reducing tangling. Gaps exist between the protrusions 13 on the sides of the separators 2, further separating the wires and making the wiring within the wire trough 1 more organized.

[0026] See Figure 2 and Figure 4 A base plate 3 is installed in the wire trough 1 on the side away from the top cover 4. The upper surface of the base plate 3 is evenly provided with a plurality of first fixing holes 8 for inserting screws. The side of the wire trough 1 facing the base plate 3 is evenly provided with a plurality of second fixing holes 12. The first fixing holes 8 and the second fixing holes 12 are aligned so that the screws can be installed at the required position after passing through the channel formed by the first fixing holes 8 and the second fixing holes 12, thereby restricting the position of the wire trough 1. At the same time, the position of the base plate 3 in the wire trough 1 is restricted.

[0027] See Figures 1-5The upper side of the base plate 3 has multiple layers of strips 5 arranged parallel to the base plate 3. Two through holes 10 are formed on the upper surface of each layer 5. A guide rod 6 is inserted into each through hole 10. The outer surface of the guide rod 6 near the base plate 3 is machined with external threads. An internal threaded sleeve 7 is threaded to the threaded end of the guide rod 6. A blind hole is formed in the area of ​​the base plate 3 where the internal threaded sleeve 7 is installed, allowing one end of the internal threaded sleeve 7 to be glued into the blind hole, thus completing the assembly of the internal threaded sleeve 7 and the base plate 3. A support sleeve 9 is arranged concentrically with the through holes 10 on the upper side of the through holes 10. One end of the support sleeve 9 is connected to the layer 5. The connection is fixed, and a rubber sleeve 11 is glued inside the support sleeve 9. The rubber sleeve 11 wraps around the guide rod 6. Multiple first annular protrusions are evenly installed on the guide rod 6, and multiple second annular protrusions are evenly installed on the inner surface of the rubber sleeve 11. The first annular protrusions on the guide rod 6 and the second annular protrusions on the inner surface of the rubber sleeve 11 increase the friction between the guide rod 6 and the rubber sleeve 11, making the position of the layered strips 5 on the guide rod 6 more stable. Multiple layers of layered strips 5 are set in the wire trough 1, which, together with the guide rod 6, support sleeve 9 and rubber sleeve 11, allow multiple wires to be laid in layers. Compared with the traditional case where wires are crimped together in the wire trough, this layered method can effectively reduce the resistance when pulling out damaged wires later, reducing maintenance time and labor costs. Since the position of the layered strips 5 on the guide rod 6 is adjustable, this feature allows the spacing of the layered strips 5 to be flexibly adjusted according to the distribution requirements of the wires in practical applications. Specifically, in the area where the wires enter the cable tray 1, the spacing between the layered strips 5 can be reduced, making the wires more compact and orderly when they enter; while in the area away from the wires, the spacing between the layered strips 5 can be increased, providing more space for the wires to extend. In this way, not only is the space utilization within the cable tray 1 optimized, but the mutual compression and tangling of the wires can also be effectively reduced, ensuring the neatness and rationality of the wiring within the cable tray 1.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
