Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable equipment technology, and specifically to a quick-installation cable tray. Background Technology
[0002] In the renovation of old houses and the wiring of temporary residences, cable trays are often used for line protection. Currently, cable trays are composed of two parts, upper and lower. During installation, the base of the cable tray needs to be fixed first, and then the cover plate needs to be installed. The two are usually fixed with a clip, which is troublesome to install. If the clip is not aligned, the structure can be easily damaged during installation. Moreover, both parts need to be taken into account during manufacturing and transportation, which increases costs and difficulty.
[0003] Chinese Patent Publication No. CN211930164U, Publication Date: November 13, 2020, discloses a Chinese patent entitled "Three-Layer Separable Cable Tray." This patent includes a U-shaped trough and a top cover body. The top of the U-shaped trough is fitted with a corresponding top cover body. The U-shaped trough includes a bottom plate, side plates, a first snap fastener, and partition holes. The bottom plate has symmetrically arranged side plates, and a first snap fastener is located between the two side plates. The front of the side plates has partition holes arranged at equal intervals. The U-shaped trough and top cover body are separate, and the snap fastener structure on both sides causes inconvenience in installation, manufacturing, and transportation. Utility Model Content
[0004] This utility model discloses a quick-installation cable tray. By setting a cover plate and a base integrally formed with a first barb and a second barb, the cable tray can be quickly installed, ensuring convenient installation and stability, and facilitating transportation and manufacturing.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a quick-installation cable tray, comprising an integrally formed base and cover plate. One side of the base is rotatably connected to the cover plate via an arc-shaped ridge, and the top of the other side is bent inward to form a support. A snap-fit plate is provided below the corresponding side of the cover plate. A first barb is provided on the inner side of the cover plate near the snap-fit plate, with the bottom end of the first barb inclined towards the snap-fit plate. A second barb is provided on the inner wall of the top of the corresponding side of the base, and a triangular notch is provided on the outer wall of the base at the second barb. By providing the first and second barbs and the cover plate and base being integrally formed, the cable tray can be quickly installed, ensuring convenient installation and stability, and facilitating transportation and manufacturing.
[0006] Preferably, the base has a storage compartment extending through both ends, with a cover plate placed over the opening of the compartment. The storage compartment is rectangular and open at the top, used to store wires. This rectangular design efficiently stores wires, preventing tangled cables and improving the tidiness of the cable tray. The neatly stored wires reduce the risk of short circuits or electric shocks caused by exposed cables, thus improving the safety of the cable tray.
[0007] Preferably, the bottom end of the first barb is an inverted triangle with an upward-facing cross-section. The top of the first barb is located on the inner wall of the top of the cover plate. Above the inverted triangle, the first barb is a rectangular plate, and there is a distance between it and the snap-fit plate. The inverted triangle structure increases the contact area between the first and second barbs, making the engagement of the cover plate and the base tighter and improving the overall stability of the cable tray. The distance design between the rectangular plate and the snap-fit plate provides space for the elastic deformation and engagement of the first barb, allowing the side wall of the base with the second barb to extend between the rectangular plate and the snap-fit plate, making installation and disassembly smoother.
[0008] Preferably, the first barb and the snap-fit plate are at the same height. The snap-fit plate is oriented in the same direction as the first barb, both facing the base, ensuring the snap-fit accuracy between the cover plate and the base.
[0009] Preferably, the second barb has a downward-facing triangular cross-section, with the triangular notch located on one side of the base wall where the second barb is positioned. The slope of one side of the bottom of the second barb's triangle is approximately the same as the slope of one side of the top of the first barb's inverted triangle, so that these two sides contact and engage when the cover plate and the base are engaged. This similar slope design allows the first and second barbs to fit together more naturally during engagement, reducing resistance and improving installation efficiency.
[0010] Preferably, the angle at which the triangular notch faces downward is the same as that of the second barb. Both the first and second barbs are elastic elements. The triangular notch makes it easier for the first and second barbs to engage, and makes it easier for the second barb to deform under the pressure of the first barb.
[0011] Preferably, all corners of the triangular notch are the same as the second barb. The triangular notch reduces stress concentration points, making the component less prone to fatigue fracture during long-term use and improving the overall durability of the cable tray.
[0012] Preferably, the bearing and the sidewall with the second barb form an L-shape. The sidewall with the second barb is vertical, and the bearing is horizontal. The L-shaped structure provides support for the cover plate, making it more stable after installation and reducing loosening or deformation caused by external forces.
[0013] Preferably, when the base and cover are closed, the inverted triangle at the bottom of the first barb engages below the second barb. The tight fit between the inverted triangle structure and the second barb ensures a secure connection between the cover and the base after closing, preventing loosening due to external force or vibration. This locking method effectively prevents the cover from accidentally falling off, ensuring the stability of the cable tray during long-term use and reducing maintenance costs.
[0014] Preferably, when the base and cover are closed, the bottom end of the snap-fit plate rests on the upper surface of the bearing. The engagement between the snap-fit plate and the bearing provides stable support for the cover, further enhancing the overall structural strength of the cable tray.
[0015] The beneficial effects of this utility model are as follows: By setting a first barb and a second barb, and integrally forming the cover plate and the base, this utility model enables the rapid installation of the wire trough, ensuring convenient and stable installation, and facilitating transportation and manufacturing.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] In modern architecture, industrial production, and the installation of various electrical equipment, cabling is a crucial foundational task. As a key carrier for cabling, the ease of installation, stability, and overall performance of cable trays directly impact the quality and efficiency of cabling projects. The quick-installation cable tray disclosed in this invention, by incorporating an integrally formed cover plate 2 and base 1, and featuring a first barb 2.1 and a second barb 1.2, effectively solves many problems associated with the installation, transportation, and use of traditional cable trays.
[0021] like Figure 1 and Figure 2As shown, this quick-installation cable tray mainly consists of a one-piece molded base 1 and a cover plate 2. The entire assembly is preferably made of rigid plastic. This one-piece molding manufacturing method ensures the structural stability of the cable tray from the outset. During production, the base 1 and cover plate 2 are molded in one piece using specific molds and injection molding processes, reducing potential problems such as loose connections and insufficient strength that may arise from splicing multiple parts. Simultaneously, the one-piece design greatly facilitates transportation; the cable tray is less prone to damage during transport due to loose parts or collisions, reducing transportation costs and the risk of loss.
[0022] like Figure 1 and Figure 2 As shown, one side of the base 1 is rotatably connected to the cover plate 2 via an arc-shaped ridge 1.1. The arc-shaped ridge has a certain curvature, allowing the cable tray to open and close. The design of the arc-shaped ridge 1.1 is equivalent to a natural pivot, giving the cover plate 2 the ability to rotate smoothly around the base 1. In actual operation, when wiring or maintenance is required inside the cable tray, only a light force is needed, and the cover plate 2 can easily rotate and open around the arc-shaped ridge 1.1, making operation very convenient. The curvature of the arc-shaped ridge 1.1 is carefully designed to ensure both the flexibility of rotation and a relatively stable connection between the cover plate 2 and the base 1 when not in operation, preventing it from opening on its own due to slight shaking.
[0023] like Figure 2 As shown, the top edge of the other side of the base 1 is bent inward to form a support 1.3, while a snap-fit plate 2.2 is provided below the corresponding side of the cover plate 2. Meanwhile, a first barb 2.1 is provided on the inner side of the cover plate 2 near the snap-fit plate 2.2, with its bottom end tilted towards the snap-fit plate 2.2. A second barb 1.2 is provided on the inner wall of the top edge of the corresponding side of the base 1, and a triangular notch 1.4 is provided on the outer wall of the base 1 at a position corresponding to the second barb 1.2. This series of ingenious designs together constitutes the quick-connect structure of the wire trough. When the wire trough needs to be installed, the cover plate 2 is pressed towards the base 1, at which point the first barb 2.1 and the second barb 1.2 approach each other under pressure. Due to the tilted design of the bottom end of the first barb 2.1 and the corresponding position of the second barb 1.2, the two can smoothly snap into each other, thereby achieving a quick connection between the cover plate 2 and the base 1. The triangular notch 1.4 plays a crucial auxiliary role in this process. It provides a certain deformation space for the second barb 1.2 when it engages, making the engagement process smoother and enhancing the reliability of the entire engagement structure.
[0024] like Figure 1As shown, the base 1 has a storage compartment extending through both ends, with a cover plate 2 covering the opening of the storage compartment. The storage compartment is rectangular in shape with an opening at the top. The rectangular storage compartment offers several significant advantages. First, the rectangular shape makes full use of space, efficiently storing wires of various specifications. In actual cabling scenarios, whether it's a single-strand wire or a multi-strand cable, it can be arranged orderly within the rectangular storage compartment, avoiding tangled cables and greatly improving the neatness of the cable tray. For example, in a large office cabling project, numerous network cables and electrical wires are organized using rectangular storage compartments, making the inside of the cable tray clearly visible and facilitating subsequent line inspection and maintenance. Second, neatly storing the wires within the storage compartment effectively reduces exposed cables, thereby lowering the risk of short circuits caused by exposed cables. Simultaneously, it reduces the risk of electric shock for personnel who may come into contact with the cable tray, significantly improving the safety of the cable tray.
[0025] like Figure 2 As shown, the first barb 2.1 has an upward-facing inverted triangular cross-section at its bottom. The top of the first barb 2.1 is firmly set on the inner wall of the top of the cover plate 2. Above the inverted triangle is a rectangular plate, and a distance is maintained between the rectangular plate and the snap-fit plate 2.2. The inverted triangular structure greatly increases the contact area between the first barb 2.1 and the second barb 1.2. When the two are engaged, the larger contact area means that greater friction can be generated, thus making the engagement between the cover plate 2 and the base 1 tighter and significantly improving the overall stability of the cable tray. For example, in some industrial environments with vibration, this tight engagement can ensure that the cover plate 2 and the base 1 remain firmly connected and will not loosen under long-term vibration. The distance between the rectangular plate and the snap-fit plate 2.2 provides the necessary space for the elastic deformation of the first barb 2.1 during the engagement process. During installation, the side wall of the base 1 with the second barb 1.2 can smoothly penetrate between the rectangular plate and the snap-fit plate 2.2, making the installation and disassembly operations smoother. When it is necessary to open the cable tray for cable adjustment, the first barb 2.1 can be elastically deformed to a certain extent, making it easy to separate from the second barb 1.2 without causing operational difficulties due to excessive clamping.
[0026] like Figure 2 As shown, the first barb 2.1 and the snap-fit plate 2.2 are at the same height, and their orientation is both towards the base 1. This design plays a crucial role in ensuring the engagement accuracy of the cover plate 2 and the base 1. During the manufacturing process, the uniform height and orientation facilitate mold design and manufacturing, effectively improving production efficiency and product quality consistency. In actual installation, the identical height and orientation design allows the snap-fit plate 2.2 and the first barb 2.1 to be accurately aligned, ensuring the tightness and stability of the engagement between the cover plate 2 and the base 1.
[0027] like Figure 2 As shown, the cross-section of the second barb 1.2 is a downward-facing triangular shape, with the triangular notch 1.4 located on one side of the base 1 wall where the second barb 1.2 is located. It is worth noting that the slope of one side of the triangular base of the second barb 1.2 is approximately the same as the slope of one side of the inverted triangle of the first barb 2.1. When the cover plate 2 and the base 1 are engaged, these two sides can naturally contact and engage together. This similar slope design allows the first barb 2.1 and the second barb 1.2 to engage more smoothly, reducing potential resistance during engagement. In actual installation, workers can clearly feel that due to this slope design, the first barb 2.1 and the second barb 1.2 can quickly and accurately engage with just a light press on the cover plate 2, greatly improving installation efficiency. For example, in emergency repair projects, rapid engagement can save valuable time and restore normal line operation as quickly as possible.
[0028] like Figure 1As shown, the triangular notch 1.4 not only has the same downward angle as the second barb 1.2, but all its angles are also the same as the second barb 1.2. The triangular notch 1.4 has multiple benefits. First, since both the first barb 2.1 and the second barb 1.2 are elastic elements, the presence of the triangular notch 1.4 makes the engagement of the first barb 2.1 and the second barb 1.2 smoother. During engagement, when the second barb 1.2 is squeezed by the first barb 2.1, it can deform to a certain extent through the triangular notch 1.4, thus making it easier to engage with the first barb 2.1. The characteristic that both the first barb 2.1 and the second barb 1.2 are elastic elements also means that, in actual operation, when the cover plate 2 engages with the base 1, the presence of the triangular notch 1.4 acts like a lubricant, making the engagement of the first barb 2.1 and the second barb 1.2 smoother and more unobstructed. Specifically, during the engagement process, as the first hook 2.1 gradually approaches the second hook 1.2 as the cover plate 2 is pressed down, the first hook 2.1 exerts a squeezing effect on the second hook 1.2. At this time, the triangular notch 1.4 becomes the key space for the deformation of the second hook 1.2. Due to the unique shape and position of the triangular notch 1.4, the second hook 1.2 can undergo a certain degree of elastic deformation when squeezed by the first hook 2.1. This deformation allows the second hook 1.2 to adjust its shape more flexibly, making it easier to achieve a precise engagement with the first hook 2.1. For example, during the actual installation of the cable tray, the construction workers can clearly feel that when the cover plate 2 is gently pressed, the first hook 2.1 and the second hook 1.2 can quickly and naturally engage together due to the effect of the triangular notch 1.4, greatly saving installation time and improving work efficiency. From the perspective of the long-term use of the cable tray, the design of the triangular notch 1.4 has a more profound significance. In daily use, the opening and closing of the cover plate 2 is a relatively frequent operation. During each opening and closing, the second barb 1.2 is subjected to varying degrees of compression from the first barb 2.1, resulting in the side of the second barb 1.2 located on the side wall of the base 1 being frequently subjected to tensile or compressive forces. If this stress is concentrated at certain specific points, it can easily lead to fatigue fracture of the component over time, thus affecting the overall service life and stability of the cable tray. The ingenious design of the triangular notch 1.4 effectively solves this problem. The special shape of the triangular notch 1.4 acts like a stress diffuser. When the second barb 1.2 is compressed, the triangular notch 1.4 can evenly distribute the stress to the surrounding area, preventing excessive stress concentration at a single point. In this way, during the frequent opening and closing of the cover plate 2, the local stress borne by the second barb 1.2 is effectively alleviated, greatly reducing the degree of fatigue.For example, in places where cable trays need to be frequently opened for line inspection or maintenance, such as data center server rooms, the presence of the triangular notch 1.4 allows the second barb 1.2 to maintain good elasticity and structural integrity even after long-term use, effectively extending the service life of the cable trays and reducing the replacement and repair costs required due to component damage.
[0029] like Figure 1 and Figure 2 As shown, the support 1.3 and the side wall with the second barb 1.2 together form an L-shaped structure. The side wall with the second barb 1.2 is vertical, while the support 1.3 is horizontal. This L-shaped structure provides strong support for the cover plate 2, making it more stable after installation. In practical applications, the cable tray may be subjected to external forces from different directions, such as horizontal tension and vertical pressure. The L-shaped structure effectively resists these external forces, reducing the risk of the cover plate 2 loosening or deforming due to external forces. For example, when the cable tray is installed on the ceiling, even if it is subjected to ceiling vibration or occasional impacts, the L-shaped structure ensures a stable connection between the cover plate 2 and the base 1, preventing the cover plate 2 from easily falling off and ensuring the safety of the wires inside the cable tray.
[0030] When the base 1 and cover 2 are closed, the inverted triangle at the bottom of the first barb 2.1 will precisely engage below the second barb 1.2. This tight fit between the inverted triangle structure and the second barb 1.2 ensures a secure connection between the cover 2 and the base 1 after closing. In practical use, this engagement method effectively prevents the cover 2 from accidentally falling off due to external force or vibration, regardless of whether it is slight vibration in daily environments or larger vibration in harsh industrial environments. For example, in the wiring of some large mechanical equipment, the equipment will generate strong vibrations during operation, but due to the tight engagement structure of the cable tray, the cable tray can remain stable and reliable under long-term vibration, reducing the maintenance work required due to the loosening of the cover 2 and lowering maintenance costs. At the same time, when the base 1 and cover 2 are closed, the bottom end of the snap-fit plate 2.2 will accurately rest on the upper surface of the support 1.3. This engagement between the snap-fit plate 2.2 and the support 1.3 provides additional stable support for the cover 2, further enhancing the overall structural strength of the cable tray. When subjected to significant external forces, the engagement of the snap-fit plate 2.2 and the bearing 1.3 disperses the force, preventing damage to the cable tray due to excessive local stress and thus extending its service life. When the cable tray is closed, the snap-fit plate 2.2 engages with the bearing 1.3 to form a normal closed surface, protecting the first barb 2.1 and the second barb 1.2 and ensuring long-term stable fixation.
[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
