Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray for low-voltage engineering. Background Technology

[0002] Low-voltage electrical engineering is a category of electrical applications. Electrical applications can be divided into two categories according to the strength of power transmission: high-voltage and low-voltage. During the construction of low-voltage electrical engineering, cables need to be routed through cable trays to avoid exposed and messy cables, which can protect the cables and improve the overall aesthetics.

[0003] The cable tray for low-voltage engineering disclosed in Chinese patent CN219659333U includes a tray body, a top cover, and plug blocks; several sets of sockets are fixedly welded to both sides of the inner wall of the tray body, and the several sets of sockets are equidistantly distributed in the tray body; slots are opened on the inner side of the sockets; the two ends of the plug blocks are inserted into the slots from top to bottom; there are multiple sets of plug blocks, and each set of plug blocks has a plastic wire retaining ring integrally formed on the top; the number of plastic wire retaining rings on the top of each set of plug blocks is three.

[0004] The aforementioned existing cable trays for low-voltage engineering have significant drawbacks in practical applications: First, their design relies on a simple slot structure to fix the top cover. This fixing method lacks stability and is prone to separation from the cable tray due to external force or prolonged use, exposing the internal cables. This not only affects aesthetics but may also accelerate cable aging due to environmental factors such as dust and moisture, shortening their lifespan. Second, the cable trays use multiple sets of plugs stacked and inserted into sockets to achieve layered cable routing. Although this design theoretically supports the neat arrangement of multiple sets of cables, the large number of sockets in the cable tray means that each socket requires a separate plug installation, making the process cumbersome and time-consuming, greatly reducing construction efficiency and increasing labor costs.

[0005] To solve the above problems, this utility model proposes a cable tray for low-voltage engineering. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a cable tray for low-voltage engineering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage electrical wiring trough, including a trough body, a slot is provided at the top inner side of the trough body, a cover plate is provided inside the slot for limiting engagement, multiple sets of limiting seats are provided on both sides of the inner wall of the trough body, a base is slidably inserted into the inside of each limiting seat, three sliders are slidably installed on the upper surface of each base, and wire clamping plates are fixedly connected to both sides of the top of each slider, and two corresponding wire clamping plates are engaged and connected by a buckle assembly.

[0008] The present invention is further configured such that the wire clamping plate is composed of three semi-circular plates connected end to end.

[0009] The present invention is further configured such that the buckle assembly includes a female buckle and a male buckle, both of which are fixedly installed at the connection of the three semicircular plates, and the female buckle and the male buckle are correspondingly arranged on the opposite surfaces of the two wire clamping plates.

[0010] This invention is further configured such that a T-shaped groove is formed on the upper surface of the base, and a slider is slidably installed within the T-shaped groove. The base can slide within the limiting seat, facilitating flexible adjustment of its position according to the number and layout of cables, and adapting to different wiring requirements.

[0011] The present invention is further configured such that multiple limiting rods are slidably installed on the side wall of the groove, and multiple limiting grooves are opened on the side wall of the cover plate. The limiting rods and the limiting grooves are correspondingly inserted and engaged, and the end of the limiting rod near the limiting groove is set with an inclined surface.

[0012] The present invention is further configured such that a fixing plate is fixedly installed at the end of the limiting rod away from the limiting groove, and a spring is sleeved on the outer side of the limiting rod. One end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the outer wall of the groove. The fixing plates on the same side are fixedly connected to each other by a connecting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This low-voltage wiring duct uses a combination of limit seats, bases, sliders, cable clamps, female clips, and male clips. The base is inserted into the limit seat, the slider is adjusted to position the cable clamp, and the cable is placed between the semi-circular plates. The cable is then secured by the female and male clips, achieving layered wiring. Operation is convenient; only one cable clamp needs to be installed on each limit seat during installation. It accommodates multiple cable arrangements, improving work efficiency.

[0015] 2. This low-voltage wiring trough uses a T-shaped sliding groove, a limiting rod, a limiting slot, a fixing plate, a spring, and a connecting plate. When the cover plate is inserted into the slot, the limiting rod slides under the action of the inclined surface and compresses the spring. After the spring returns to its original position, the limiting rod locks into the limiting slot, completing a stable installation. For disassembly, simply pull the connecting plate to remove the cover plate. It offers strong stability and prevents cable exposure. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a low-voltage electrical wiring trough, including a trough body 1. A slot 2 is formed at the top inner side of the trough body 1. A cover plate 3 is fitted inside the slot 2 for limiting engagement. Multiple limiting rods 11 are slidably installed on the side wall of the trough body 1. Multiple limiting grooves 12 are formed on the side wall of the cover plate 3. The limiting rods 11 and limiting grooves 12 are correspondingly inserted and engaged. The end of the limiting rod 11 near the limiting groove 12 is inclined. A fixing plate 13 is fixedly installed at the end of each limiting rod 11 away from the limiting groove 12. A spring 14 is sleeved on the outer side of the limiting rod 11. One end of the spring 14 is fixedly connected to the fixing plate 13, and the other end of the spring 14 is fixedly connected to the outer wall of the trough body 1. The fixing plates 13 on the same side are fixedly connected by connecting plates 15.

[0026] The insertion and engagement of the limiting rod 11 and the limiting groove 12, combined with the elastic support of the spring 14, effectively prevents the cover plate 3 from separating from the groove 1, avoiding cable exposure and extending cable life. The beveled design of the limiting rod 11 facilitates the quick installation and removal of the cover plate 3, improving operational efficiency.

[0027] Multiple sets of limiting seats 4 are provided on both sides of the inner wall of the tank 1, and each limiting seat 4 has a base 5 that is slidably inserted into it. The base 5 can slide within the limiting seat 4, which makes it easy to flexibly adjust its position according to the number and layout of cables to adapt to different wiring needs.

[0028] Three sliders 6 are slidably mounted on the upper surface of the base 5. Specifically, a T-shaped groove 10 is formed on the upper surface of the base 5, and the sliders 6 are slidably mounted within the T-shaped groove 10. The sliders 6 can slide freely within the T-shaped groove 10, which facilitates the adjustment of the position of the cable clamping plate 7 according to the thickness and quantity of the cables, thereby improving the flexibility of wiring.

[0029] Both sides of the top of the slider 6 are fixed with wire clamping plates 7, and the two corresponding wire clamping plates 7 are connected by a snap-fit ​​assembly.

[0030] Specifically, the cable clamping plate 7 consists of three semi-circular plates connected end to end. The clamping assembly includes a female clamp 8 and a male clamp 9, both of which are fixedly installed at the connection points of the three semi-circular plates. The female clamp 8 and male clamp 9 are correspondingly positioned on the opposite surfaces of the two cable clamping plates 7. The three semi-circular plates on the two cable clamping plates 7 form a three-layer cable clamping groove, allowing for layered cable arrangement. The snap-fit ​​connection of the female clamp 8 and male clamp 9 simplifies the installation and disassembly process of the cable clamping plate 7, improving operational efficiency.

[0031] Working principle:

[0032] In use, first insert the base 5 into the limiting seat 4 to complete the initial installation of the cable clamping plate 7, and then slide the slider 6 in the T-shaped groove 10 of the base 5 to precisely adjust the position of the cable clamping plate 7. In the initial state, the buckle assembly (female buckle 8 and male buckle 9) is not engaged, which makes it easy to place the cable between the corresponding semicircular plates of the two cable clamping plates 7. Then, the two semicircular plates are tightly fixed by the engagement of the female buckle 8 and the male buckle 9 to realize the layered routing of multiple sets of cables. Next, insert the cover plate 3 into the slot 2 of the groove 1. The cover plate 3 contacts the inclined surface of the limiting rod 11, pushing the limiting rod 11 to slide outward and stretching the spring 14. When the limiting groove 12 of the cover plate 3 is aligned with the limiting rod 11, the spring 14 returns to its original position, driving the limiting rod 11 to engage in the limiting groove 12, thus completing the secure installation of the cover plate 3 and ensuring a tight connection between the groove 1 and the cover plate 3 to prevent cable exposure. When disassembling, simply pull the connecting plate 15 to disengage the limiting rod 11 from the limiting groove 12, and the cover plate 3 can be easily removed. The advantages of the corresponding structure include: the plug-in structure of the base 5 and the limiting seat 4 enables modular installation and facilitates quick positioning; the sliding structure of the slider 6 and the T-shaped slide groove 10 provides precise positioning and flexible adjustment; the cable clamping plate 7 and the buckle assembly (female buckle 8 and male buckle 9) ensure that the cable is firmly fixed and supports quick installation; the beveled fit between the cover plate 3 and the limiting rod 11 and the elastic structure of the spring 14 enhance the stability of the cover plate connection; the linkage structure between the connecting plate 15 and the limiting rod 11 simplifies the disassembly process and improves the ease of operation.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
