Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray that can be quickly installed. Background Technology

[0002] Cable trays play a vital role in the power engineering and construction industries. As a key component, their design and installation quality have a decisive impact on the performance and safety of the entire electrical system. Especially in the wiring of large buildings or industrial facilities, cable trays are used to support, fix, and protect cable lines, ensuring the safe and stable transmission of power. With the development of modern construction, the demand for cable trays goes beyond basic functional requirements, also requiring quick installation, ease of maintenance, and a good aesthetic appearance.

[0003] Specifically, existing quick-installation cable trays have gradually revealed significant limitations in practical applications. For example, utility model patent CN 220209866 U discloses a quick-installation cable tray, including a tray body and a detachable connecting assembly between adjacent tray bodies. This design improves the ease of installation and disassembly and enhances aesthetics by reducing the use of bolts. However, this design has the following prominent problems:

[0004] First, although the use of bolts is reduced, the connectors in the aforementioned patent only have a fixing structure and lack an effective limiting structure. This means that in actual use, especially under vibration or external force, the tightness of the connection is poor, which may lead to loosening or even detachment, increasing safety hazards. Second, due to the lack of a limiting structure, the connection between adjacent cable trays is not stable enough. This not only affects the overall structural stability but may also cause cable wear due to slight movement, thereby affecting the cable's service life and the system's reliability.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a cable tray design that allows for rapid installation. This cable tray should significantly improve installation efficiency while ensuring the tightness and stability of connections, better meeting the requirements of modern construction projects for efficiency, safety, and aesthetics, and providing strong support for the sustainable development of the power engineering and construction industries. In particular, it is necessary to introduce an effective limiting mechanism to enhance the stability of the connection points, while simplifying the installation process and reducing maintenance costs. Utility Model Content

[0006] The purpose of this invention is to provide a cable tray that can be installed quickly, solving the problem that existing technologies only have a fixed structure for the connectors without an effective limiting structure. This means that in actual use, especially when subjected to vibration or external forces, the tightness of the connection is poor, which may lead to loosening or even detachment, increasing safety hazards.

[0007] To achieve the above objectives, this utility model provides a cable tray that can be installed quickly, comprising several trays, with each pair of adjacent trays connected by positioning elements.

[0008] The positioning component includes a bottom plate and two side plates fixedly connected to both ends of the bottom plate. Bottom grooves are provided on both sides of the bottom of the cable tray, and two side grooves are provided on both sides of the cable tray respectively communicating with the adjacent bottom grooves.

[0009] The width of the bottom groove and the side groove is half the width of the bottom plate. The bottom of the bottom groove is connected to several positioning posts. The top of the bottom plate is provided with several positioning holes that are adapted to the positioning posts. The top of the side plate is fixedly connected to a positioning plate that can be detachably connected to the side wall of the cable tray.

[0010] One end of the cable tray is provided with a plug slot, and the other end is fixedly connected with a plug plate that is compatible with the plug slot.

[0011] The cable tray has two positioning slots on each side that are connected to the adjacent side slots and are adapted to the positioning plate.

[0012] The plug plate is made of metal, and several elastic protrusions are connected to both sides of the inner wall of the plug groove.

[0013] The positioning plate has two positioning screws threadedly connected to one side, and the inner wall of the positioning groove has a threaded hole that passes through the bridge and is adapted to the positioning screws.

[0014] The bottom plate has the same length as the width of the cable tray, and the bottom plate is made of metal.

[0015] This utility model discloses a quick-installation cable tray. Through the design of a bottom plate and positioning holes that engage with positioning posts within the bottom groove, it solves the problem of poor tightness at the joints of traditional cable trays. This effectively prevents loosening or even detachment due to vibration or external forces, enhancing the overall structural safety. Furthermore, the detachable connection between the positioning plate and the side wall of the cable tray not only simplifies the installation process but also provides an additional limiting mechanism, making the connection between adjacent cable trays more stable. This reduces the risk of cable wear due to minor movements, extending cable life and system reliability. The entire design avoids complex bolt connections, significantly reducing installation time and maintenance costs while maintaining a good appearance. This makes the cable tray not only easy to install and maintain but also adaptable to various complex environments, improving overall project quality and user experience. Attached Figure Description

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a cable tray that can be quickly installed according to this embodiment includes several cable trays 1, and each pair of adjacent cable trays 1 are connected by positioning members 2.

[0026] The positioning component 2 includes a bottom plate 8 and two side plates 12 fixedly connected to both ends of the bottom plate 8. Bottom grooves 4 are provided on both sides of the bottom of the cable tray 1, and two side grooves 3 are provided on both sides of the cable tray 1 respectively communicating with the adjacent bottom grooves 4.

[0027] The width of both the bottom groove 4 and the side groove 3 is half the width of the bottom plate 8. Several positioning posts 5 are connected to the bottom of the bottom groove 4. Several positioning holes 9 that are adapted to the positioning posts 5 are opened on the top of the bottom plate 8. A positioning plate 10 that can be detachably connected to the side wall of the cable tray 1 is fixedly connected to the top of the side plate 12.

[0028] First, place two adjacent cable trays 1 in the desired positions, ensuring their bottom grooves 4 and side grooves 3 are aligned. Each cable tray 1 has a bottom groove 4 on both sides of its bottom, and two side grooves 3 on each side, each communicating with the adjacent bottom groove 4. The positioning component 2 includes a bottom plate 8 and two side plates 12 fixedly connected to its ends. The width of the bottom plate 8 is half the width of the bottom groove 4 and the side groove 3. The top of the bottom plate 8 has several positioning holes 9, which are adapted to the positioning posts 5 at the bottom of the bottom groove 4. During installation, the bottom plate 8 is inserted into the bottom groove 4, aligning the positioning holes 9 with the positioning posts 5 and inserting them, thus achieving a stable connection between the bottom plate 8 and the bottom groove 4. Then, the positioning plates 10 fixed to the top of the side plates 12 are detachably connected to the side wall of the cable tray 1, further enhancing the connection stability between adjacent cable trays. The entire installation process requires no bolts and can be completed through simple plug-in and snap-fit ​​operations, significantly improving installation efficiency.

[0029] Example 2

[0030] Please see Figure 1-5 As shown in this embodiment, a cable tray that can be quickly installed has a plug-in slot 6 at one end and a plug-in plate 7 that matches the plug-in slot 6 fixedly connected to the other end. Specifically, the plug-in slot 6 at one end of the cable tray 1 and the plug-in plate 7 fixedly connected to the other end allow adjacent cable trays 1 to be quickly connected by plugging. During installation, simply inserting the plug-in plate 7 of one cable tray 1 into the plug-in slot 6 of another cable tray 1 achieves initial positioning and connection, simplifying the installation steps and improving installation efficiency and convenience.

[0031] The connector plate 7 is made of metal, and several elastic protrusions are connected to both sides of the inner wall of the connector slot 6. Specifically, by using metal for the connector plate 7 and connecting several elastic protrusions to both sides of the inner wall of the connector slot 6, not only is the strength and durability of the connector plate 7 improved, but the elastic protrusions also increase the friction between the connector plate 7 and the connector slot 6, preventing loosening or detachment. This design ensures that the connection remains stable when subjected to vibration or external force, thereby improving connection safety and extending service life.

[0032] Example 3

[0033] Please see Figure 1-5As shown in this embodiment, a cable tray that can be quickly installed has two positioning slots 13 on both sides of the tray 1, which communicate with the adjacent side slots 3 and are adapted to the positioning plate 10. Specifically, the positioning slots 13 on both sides of the tray 1, which communicate with the adjacent side slots 3 and are adapted to the positioning plate 10, further enhance the connection stability between adjacent trays. During installation, the positioning plate 10 can be inserted into the positioning slot 13 and connected to the screw hole on the inner wall of the positioning slot 13 through the positioning screw 11, ensuring the tightness and firmness between the trays 1, and achieving the effect of enhancing the overall structural stability and reliability.

[0034] Two positioning screws 11 are threadedly connected to one side of the positioning plate 10. A threaded hole, penetrating the cable tray 1 and matching the positioning screws 11, is provided on the inner wall of the positioning groove 13. Specifically, the two positioning screws 11 threaded to one side of the positioning plate 10 and the threaded hole in the inner wall of the positioning groove 13, penetrating the cable tray 1 and matching the positioning screws 11, enable a detachable connection between the positioning plate 10 and the cable tray 1. During installation, after the positioning plate 10 is inserted into the positioning groove 13, tightening the positioning screws 11 quickly locks the position, ensuring the connection's firmness and accuracy, thus enhancing connection stability and facilitating maintenance.

[0035] The bottom plate 8 has the same length as the width of the cable tray 1 and is made of metal. Specifically, the design of the bottom plate 8 having the same length as the width of the cable tray 1 and being made of metal ensures that the bottom plate 8 has sufficient strength and stability. After the bottom plate 8 is inserted into the bottom groove 4 and cooperates with the positioning post 5, it can provide strong support, avoiding deformation or damage caused by bearing heavy objects, thereby improving the load-bearing capacity and long-term reliability of the entire cable tray system. In addition, the choice of metal material also improves corrosion resistance and extends the service life of the equipment.

[0036] This solution includes the following workflow:

[0037] First, place two adjacent cable trays 1 in the desired positions, ensuring that their bottom grooves 4 and side grooves 3 are aligned. Each cable tray 1 has a connector slot 6 at one end and a connector plate 7 that matches the connector slot 6 is fixedly connected to the other end. By inserting the connector plate 7 of one cable tray 1 into the connector slot 6 of the other cable tray 1, initial positioning and connection can be achieved, simplifying the installation process and improving efficiency. The connector plate 7 is made of metal, and several elastic protrusions are connected to both sides of the inner wall of the connector slot 6. This design not only improves the strength and durability of the connector plate 7 but also increases the friction at the connection point, preventing loosening or detachment. Next, the positioning component 2 includes a bottom plate 8 and two side plates 12 fixedly connected to its ends. The width of the bottom plate 8 is half the width of the bottom groove 4 and the side groove 3, and its length is the same as the width of the cable tray 1, and it is made of metal. Several positioning posts 5 are connected to the bottom of the bottom groove 4, and several positioning holes 9 that match the positioning posts 5 are provided on the top of the bottom plate 8. During installation, the bottom plate 8 is inserted into the bottom groove 4, and the positioning hole 9 is aligned with the positioning post 5 and inserted to achieve a stable connection between the bottom plate 8 and the bottom groove 4. After insertion, the bottom plate 8 provides strong support, preventing deformation or damage due to heavy loads. The metal material also enhances corrosion resistance and extends service life. Then, the positioning plate 10, fixed to the top of the side plate 12, is detachably connected to the side wall of the cable tray 1, further enhancing the connection stability between adjacent cable trays. Two positioning grooves 13 are provided on both sides of the cable tray 1, communicating with the adjacent side groove 3 and compatible with the positioning plate 10. Two positioning screws 11 are threaded onto one side of the positioning plate 10. The inner wall of the positioning groove 13 has screw holes that penetrate the cable tray 1 and are compatible with the positioning screws 11. During installation, after the positioning plate 10 is inserted into the positioning groove 13, tightening the positioning screws 11 quickly locks the position, ensuring a firm and accurate connection, thereby enhancing the overall structural stability and reliability. The entire installation process requires no bolts and can be completed through simple plug-in, snap-fit, and tightening operations, significantly improving installation efficiency.

[0038] This cable tray design significantly improves installation efficiency while ensuring the tightness and stability of connections, better meeting the requirements of modern construction projects for efficiency, safety, and aesthetics, and providing strong support for the sustainable development of the power engineering and construction industries. Specifically, the design of the bottom plate 8 and positioning holes 9 cooperating with the positioning posts 5 in the bottom groove 4 solves the problem of poor tightness at the connection of traditional cable trays, effectively preventing loosening or even detachment due to vibration or external forces, and enhancing the safety of the overall structure. The cooperation design of the plug-in groove 6 and plug-in plate 7 simplifies the initial connection between the cable trays, and the addition of elastic protrusions further improves the stability of the connection and extends the service life of the equipment. The combination of positioning plate 10, positioning screw 11, and positioning groove 13 achieves precise locking between cable trays, ensuring the tightness and firmness between adjacent cable trays, reducing the risk of cable wear caused by minor movements, extending the service life of cables and the reliability of the system. The bottom plate 8 is made of metal and its length is the same as the width of the cable tray 1, providing strong support capacity, avoiding deformation or damage caused by bearing heavy objects, while improving corrosion resistance and extending the overall life of the equipment. In addition, the entire design avoids complex bolt connections, greatly reducing installation time and maintenance costs, while maintaining a good appearance. This makes the cable tray not only easy to install and maintain, but also adaptable to the needs of various complex environments, improving the overall project quality and user experience.
