Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a clamp-type cable tray connection assembly. Background Technology

[0002] Cable trays are commonly used support and protection devices for cable laying in electrical equipment power supply systems, serving to protect and guide the cables laid within them. During installation, multiple cable trays are typically connected using bolts and connecting plates.

[0003] However, existing connection methods have the following drawbacks:

[0004] 1. Traditional connecting plates require many screws and are costly: Traditional steel cable tray connections involve drilling corresponding through holes in the connecting plates and the cable trays to be connected, and fixing them to the cable tray body with screws to ensure the connection strength specified in national standards. This requires many screws, is more complicated to operate, and has low installation efficiency.

[0005] 2. Traditional connecting plates are cumbersome to install: The installation and removal process is complicated, which greatly increases the time spent on the project;

[0006] 3. High maintenance costs: A large number of screws are required, and the screws are prone to rust, which affects the overall appearance and service life of the product, thus increasing the overall cost of the product. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a clamp-type cable tray connection assembly to solve the technical problem of low installation efficiency in the prior art.

[0008] This utility model is achieved by the following technical solution: a clamp-type cable tray connection assembly, including an outer connector and an inner connector;

[0009] Both ends of the external connector are provided with external connection groups, and the external connection groups include slots and external connection holes arranged side by side;

[0010] Both ends of the inner connector are provided with inner connecting groups. The inner connecting group includes a tenon and an inner connecting hole. Each inner connecting group corresponds to each outer connecting group. The tenon is inserted into the slot. The outer connecting hole corresponds to the inner connecting hole. The outer connecting hole and the inner connecting hole are used for fastening bolts to pass through.

[0011] The outer connector and the inner connector cooperate to form a connecting assembly, and the two ends of the connecting assembly are respectively used to fix the ends of two adjacent cable trays.

[0012] In one possible implementation, each of the outer connecting groups has two slots arranged side by side in parallel, and the outer connecting hole is located inside the slots; correspondingly, each of the inner connecting groups has two tenons arranged side by side in parallel, and the inner connecting hole is located inside the tenons.

[0013] In one possible implementation, the tenon is formed by cutting the outer connector and bending it outward by 90°.

[0014] In one possible implementation, the two tenons of the same inner connection group are arranged opposite each other to form a window.

[0015] In one possible implementation, the external connector is provided with a circular groove, and the circular groove is disposed between the two slots.

[0016] In one possible implementation, each end of the external connector has two external connection groups arranged in parallel, and each end of the internal connector has two internal connection groups arranged in parallel, with each internal connection group corresponding to each external connection group.

[0017] In one possible implementation, the lower end of the external connector is provided with a support plate for supporting the cable tray.

[0018] In one possible implementation, the support plate is formed by bending the lower end of the outer connector inward at a 90° angle.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the external connector and the internal connector can be precisely aligned by the tenon and slot. The cable tray can be initially fixed by clamping it between the external connector and the internal connector. Then, bolts are passed through the external connector and the internal connector and fixed with nuts. The composite locking mode of "bolt + plug-in limit" simplifies the bolt layout while ensuring its strength and stability coefficient. The "bolt + plug-in" combination forms an anti-loosening structure. The bolt bears the longitudinal shear force, and the tenon resists the lateral vibration, reducing the number of bolts and facilitating quick installation. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0031] like Figure 1-4The clamp-type cable tray connection assembly shown includes an outer connector 1 and an inner connector 2. Both ends of the outer connector 1 are provided with outer connecting groups, each including a slot 11 and an outer connecting hole 12 arranged side-by-side. Both ends of the inner connector 2 are provided with inner connecting groups, each including a tenon 21 and an inner connecting hole 22. Each inner connecting group corresponds one-to-one with each outer connecting group. The tenon 21 is inserted into the slot 11, and the outer connecting hole 12 corresponds to the inner connecting hole 22. The outer connecting hole 12 and the inner connecting hole 22 are used for fastening bolts to pass through. The outer connector 1 and the inner connector 2, when fitted together, form a connection assembly. Both ends of the connection assembly are used to fix the ends of two adjacent cable trays 3. It should be noted that the side wall of the cable tray 3 has multiple through holes for bolts and tenons 21 to pass through, so that the inner connector 2 and outer connector 1 located on the inner and outer sides of the cable tray 3 can be connected smoothly. The outer connector group and the inner connector group located at the same end cooperate to fix one cable tray 3, and the outer connector group and the inner connector group located at the other end cooperate to fix another cable tray 3, so that adjacent two cable trays 3 can be connected. Specifically, the outer connector hole 12 and the inner connector hole 22 are both horizontally extending elongated strips, and the corresponding through holes on the cable tray 3 are vertical. The extended strip shape limits the movement of the bolts, improving their stability. In other words, an outer connector 1 and an inner connector 2 form a set of connecting components. When two adjacent cables are connected, only two sets of connecting components are needed, and only two bolts are required in each set, greatly reducing the number of bolts and improving installation efficiency. The bolts and connecting components form an interlocking structure, and the double-sided clamping prevents the cable tray 3 from slipping or misaligning at the connection point, which helps improve its resistance to vibration, loosening, and slippage, resulting in good long-term stability.

[0032] The beneficial effects of this utility model are as follows: the outer connector 1 and the inner connector 2 can be precisely aligned by the tenon 21 and the slot 11. The cable tray 3 can be initially fixed by clamping it between the outer connector 1 and the inner connector 2. Then, bolts are passed through the outer connecting hole 12 and the inner connecting hole 22 and fixed with nuts. The composite locking mode of "bolt + plug-in limit" simplifies the bolt layout while ensuring its strength and stability coefficient. The "bolt + plug-in" combination forms an anti-loosening structure. The bolt bears the longitudinal shear force, and the tenon 21 resists the lateral vibration, reducing the number of bolts and facilitating quick installation.

[0033] Please refer to Figure 2In one possible implementation, each external connection group has two slots 11 arranged side-by-side in parallel, with an external connection hole 12 located inside the slots 11. Correspondingly, each internal connection group has two tenons 21 arranged side-by-side in parallel, with an internal connection hole 22 located inside the tenons 21. It should be noted that by providing two tenons 21, the interlocking strength between the internal connector 2 and the external connector 1 can be further improved, thereby enhancing the limiting effect of the connection assembly on the cable tray 3, and thus improving the stability of the cable tray 3.

[0034] Please refer to Figure 2 In one possible implementation, the tenon 21 is formed by cutting the outer connector 1 and bending it outward by 90°. It is easy to understand that the tenon 21 and the outer connector 1 are an integral structure, which helps to improve the structural strength of the tenon 21, thereby ensuring the stability of the tenon 21 after it is inserted into the slot 11, and thus improving the overall stability of the connecting assembly.

[0035] Please refer to Figure 2 In one possible implementation, two tenons 21 of the same inner connecting group are arranged opposite each other to form a window 23. It should be noted that the two tenons 21 are formed by cutting and bending the inner connecting member 2, with the middle part being the window 23 formed after cutting. The window 23 is rectangular, and the through hole on the cable tray 3 for the tenon 21 to pass through is also rectangular and corresponds to the window 23. The tenon 21 passes through this rectangular through hole and is then inserted into the slot 11. The outer wall of the tenon 21 can contact the cable tray 3, thereby limiting the cable tray 3.

[0036] Please refer to Figure 2 In one possible implementation, the outer connector 1 is provided with a circular groove 13, which is positioned between two slots 11. It should be noted that the circular groove 13 facilitates drilling later according to construction conditions, and the position between the two slots 11 corresponds precisely to the rectangular through hole of the cable tray 3 and the window 23 on the inner connector 2. This allows workers to drill only on the outer connector 1 according to the position of the circular groove 13, without needing to drill on the cable tray 3 and the inner connector 2, greatly reducing drilling difficulty and improving drilling efficiency.

[0037] Please refer to Figure 4In one possible implementation, the outer connector 1 has two external connection groups arranged side by side at both ends, and the inner connector 2 has two internal connection groups arranged side by side at both ends, with each internal connection group corresponding to one of the external connection groups. It should be noted that the size of the connecting assembly can be changed to accommodate different sizes of cable trays 3. When the height of the cable tray 3 is large, two external connection groups and two internal connection groups can be arranged side by side on the connecting assembly to ensure the connection strength between the connecting assembly and the cable tray 3.

[0038] Please refer to Figure 1 and Figure 3 In one possible implementation, the lower end of the external connector 1 is provided with a support plate 14, which is used to support the cable tray 3. It should be noted that when two adjacent cable trays 3 are connected by the connecting assembly, the lower wall surface of the cable tray 3 contacts the support plate 14, thereby allowing the support plate 14 to support the cable tray 3. This helps to more accurately align adjacent cable trays 3 during installation, ensuring that the connection is straight and the gaps are uniform. Good alignment and a more stable connection can make the cable tray 3 look neater and more professional.

[0039] Please refer to Figure 1 In one possible implementation, the support plate 14 is formed by bending the lower end of the outer connector 1 inward at a 90° angle. It should be noted that the support plate 14 and the outer connector 1 are an integral structure, which helps to improve the structural strength of the support plate 14, thereby ensuring the supporting effect of the support plate 14 on the cable tray 3, and thus ensuring the stability of the cable tray 3.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
