Description

Technical Field

[0001] This utility model relates to the field of bracket technology, specifically to an assembled cable tray bracket. Background Technology

[0002] In electrical installation engineering, cable tray supports are key components for supporting and fixing cable trays, and their performance and installation methods directly affect the stability and reliability of the entire electrical system. However, traditional cable tray supports have many problems in practical applications and are difficult to meet the diverse needs of modern electrical installation engineering.

[0003] Early cable tray supports were mostly one-piece structures with fixed shapes and sizes, lacking flexibility. When faced with different installation environments and cable tray layouts, these one-piece supports were often unsuitable, requiring extensive on-site cutting, welding, and other processing operations. This not only consumed time and manpower but also easily led to insecure installation due to insufficient processing precision, affecting the normal use of the cable trays. For example, in some confined or irregularly shaped locations, it was difficult to find suitable installation positions for one-piece cable tray supports, causing significant difficulties in construction.

[0004] The installation of traditional cable tray supports is also quite cumbersome. Welding or bolting is typically used. Welding requires specialized equipment and technicians, and the process generates high temperatures and sparks, posing safety hazards. Furthermore, welded supports are difficult to disassemble and adjust, hindering future maintenance and modifications. While bolting is relatively simple, over time, factors such as vibration and temperature changes can cause bolts to loosen, reducing the stability of the cable tray support and increasing safety risks to the electrical system.

[0005] Furthermore, traditional cable tray supports are not very versatile. The specifications and dimensions of cable tray supports produced by different manufacturers vary significantly, lacking a unified standard. This makes it difficult to achieve proper matching and combination when using cable trays and supports from different brands in the same project, increasing the difficulty of procurement and construction. Moreover, when it is necessary to expand or upgrade the electrical system, traditional cable tray supports often cannot meet the new requirements, necessitating the installation of a completely new support system, resulting in wasted resources and increased costs.

[0006] This utility model proposes an assembled cable tray bracket, which solves the problem of poor versatility of cable tray brackets in related technologies.

[0007] The technical solution of this utility model is as follows:

[0008] A modular cable tray bracket, comprising:

[0009] A first connector, the first connector having a first bent portion, the first bent portion having a first threaded portion;

[0010] The second connector has a second bent portion and a second threaded portion;

[0011] The third connector has a first threaded hole and a second threaded hole, the first threaded hole and the second threaded hole have opposite thread directions, the first threaded hole is threadedly connected to the first threaded portion, and the second threaded hole is connected to the second threaded portion.

[0012] As a further technical solution, the first threaded portion, the second threaded portion, the first threaded hole, and the second threaded hole have interconnected slots, and further include:

[0013] The plug-in is slidably disposed in the slot. After sliding, the plug-in slides into or out of the slot for mutual engagement of the first connector, the second connector and the third connector.

[0014] As a further technical solution, the plug-in penetrates the third connector, and the plug-in has a locking part and a fifth threaded part, the locking part and the fifth threaded part being located at opposite ends of the plug-in, the outer diameter of the fifth threaded part being larger than the diameters of the first threaded part and the second threaded part, and further includes:

[0015] A locking nut, wherein the locking nut is threaded on the fifth threaded portion.

[0016] As a further technical solution, the first connector, the second connector, and the third connector form a U-shaped clip, wherein there are at least two U-shaped clips, and the device further includes:

[0017] The bracket has a wire-holding groove;

[0018] A pressing element, which is pressed onto the bracket;

[0019] A connecting steel component, which is used for connection with the outside, wherein the U-shaped clamp is pressed onto the clamping component and extends to the connecting steel component.

[0020] As a further technical solution, both the first connector and the second connector have a sixth threaded portion, the sixth threaded portion penetrating the connecting steel member, and further include:

[0021] A fastening nut is provided, the fastening nut being threaded on the sixth threaded portion, and the fastening nut and the bracket are respectively located on both sides of the connecting steel member.

[0022] As a further technical solution, the bracket has a connecting section and a supporting section, the connecting section and the supporting section are arranged perpendicularly, and the U-shaped clip is fastened on the connecting section.

[0023] As a further technical solution, the end of the support section has a limiting stop, and the middle of the support section has a connecting hole.

[0024] As a further technical solution, the connecting section is a square tube, and the thickness of the square tube is greater than the width of the supporting section.

[0025] As a further technical solution, the longitudinal section of the support segment is a triangular structure.

[0028] The working principle and beneficial effects of this utility model are as follows:

[0029] In this invention, the first and second threaded holes on the third connector have opposite thread directions, which is a key innovation in the design of the entire cable tray support. This reverse thread design allows for precise adjustment and fixation of the first and second connectors when the first threaded part is threaded into the first threaded hole and the second threaded part is threaded into the second threaded hole. Using this threaded connection, operators can quickly assemble the first, second, and third connectors together with a simple rotation.

[0030] Because the threads of the first and second threaded holes are in opposite directions, the relative positions of the first and second connectors can be adjusted simultaneously when the third connector is rotated. When installing the cable tray bracket, if it is necessary to adjust the angle or spacing between the first and second connectors, simply rotating the third connector allows for fine-tuning of both connectors, ensuring the cable tray bracket can be accurately installed in the desired position.

[0031] This modular cable tray bracket boasts a highly flexible and versatile design. By adjusting the connection methods and angles between the first, second, and third connectors, it can adapt to different installation environments and cable tray layout requirements. The threaded connection makes later maintenance and expansion of the cable tray bracket more convenient. If a connector is damaged or needs replacement, it can be easily replaced simply by unscrewing the corresponding threaded connector. Attached Figure Description

Detailed Implementation

[0037] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0038] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0039] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Reference Figures 1-3 The first embodiment of this utility model proposes an assembled cable tray bracket, including a first connector 1, which has a first bent portion 101 and a first threaded portion 102; a second connector 2, which has a second bent portion 201 and a second threaded portion 202; and a third connector 3, which has a first threaded hole 301 and a second threaded hole 302. The threads of the first threaded hole 301 and the second threaded hole 302 are opposite in direction. The first threaded hole 301 is threadedly connected to the first threaded portion 102, and the second threaded hole 302 is connected to the second threaded portion 202.

[0042] In this embodiment, the first threaded hole 301 and the second threaded hole 302 on the third connector 3 have opposite thread directions, which is a key innovation in the design of the entire cable tray bracket. This reverse thread design allows for precise adjustment and fixation of the first connector 1 and the second connector 2 when the first threaded part 102 is threadedly connected to the first threaded hole 301 and the second threaded part 202 is connected to the second threaded hole 302. Using this threaded connection, operators can quickly assemble the first connector 1, the second connector 2, and the third connector 3 together with a simple rotation.

[0043] Because the threads of the first threaded hole 301 and the second threaded hole 302 are in opposite directions, the relative positions of the first connector 1 and the second connector 2 can be adjusted simultaneously when the third connector 3 is rotated. When installing the cable tray bracket, if it is necessary to adjust the angle or spacing between the first connector 1 and the second connector 2, simply rotate the third connector 3 to achieve fine-tuning of the first connector 1 and the second connector 2, ensuring that the cable tray bracket can be accurately installed in the required position.

[0044] This modular cable tray bracket's structural design gives it high flexibility and versatility. By adjusting the connection method and angle between the first connector 1, the second connector 2, and the third connector 3, it can adapt to different installation environments and cable tray layout requirements. The threaded connection makes the cable tray bracket easier to maintain and expand later. If a connector is damaged or needs replacement, it can be easily replaced simply by unscrewing the corresponding threaded connector.

[0045] Furthermore, the first threaded portion 102, the second threaded portion 202, the first threaded hole 301 and the second threaded hole 302 have interconnected slots 303, and also include a plug 4, which is slidably disposed in the slot 303. After sliding, the plug 4 slides into or out of the slot 303 for mutual engagement of the first connector 1, the second connector 2 and the third connector 3.

[0046] In this embodiment, after the first connector 1, the second connector 2, and the third connector 3 are initially connected by threads, the insert 4 slides into the interconnected slot 303, achieving a tight snap-fit ​​connection between the three components. This snap-fit ​​method creates multi-dimensional constraints, preventing relative rotation and displacement between the connectors in both horizontal and vertical directions. This ensures that the connections between the components remain firm and reliable even when the cable tray support bears the weight of the cable tray and external vibrations and impacts, significantly improving the overall stability of the support and effectively avoiding safety hazards caused by loose connections. The tight fit between the insert 4 and the slot 303 evenly distributes the stress borne by the cable tray support onto the three connectors. For example, in industrial plants, the cable tray may vibrate due to equipment operation. In this case, the insert 4 can effectively disperse the stress caused by the vibration, preventing stress concentration at the threaded connection, thereby extending the service life of the cable tray support and ensuring the long-term stable operation of the cable tray system.

[0047] During assembly, after completing the initial threaded connection, the operator only needs to slide the insert 4 into the slot 303 to instantly and accurately position and fix the three connectors. This operation is simple and intuitive, requiring no complicated tools or professional skills, greatly shortening assembly time. Especially in large-scale cable tray installation projects, it can significantly improve construction efficiency and reduce labor costs.

[0048] Easy disassembly and adjustment: When maintenance, adjustment, or rearrangement of the cable tray bracket is required, simply slide out insert 4 to easily loosen the threaded connectors to disassemble, replace, or reassemble the components. This convenient operation method allows the cable tray bracket to flexibly cope with different construction stages and application scenarios, reducing the waste of time and resources caused by inconvenient operation.

[0049] Furthermore, the plug-in 4 penetrates the third connector 3. The plug-in 4 has a clamping part 401 and a fifth threaded part 402. The clamping part 401 and the fifth threaded part 402 are located at both ends of the plug-in 4, respectively. The outer diameter of the fifth threaded part 402 is larger than the diameter of the first threaded part 102 and the second threaded part 202. It also includes a locking nut 5, which is threaded on the fifth threaded part 402.

[0050] In this embodiment, the insert 4 passes through the third connector 3. When the locking nut 5 is tightened on the fifth thread 402, an axial tensile force is generated. This causes the first connector 1, the second connector 2, and the third connector 3 to fit tightly together, greatly enhancing the connection strength between the components. This axial tightening force can effectively resist external forces generated by vibration and shaking during daily use of the cable tray, preventing the connectors from loosening and ensuring the stability and reliability of the cable tray support during long-term use.

[0051] The outer diameter of the fifth threaded portion 402 is larger than that of the first threaded portion 102 and the second threaded portion 202. The larger outer diameter means a larger contact area. When tightening the lock nut 5, the larger contact area provides greater friction, resulting in a better locking effect and further improving the stability of the entire connection structure.

[0052] The design of the insert 4 penetrating through the third connector 3 simplifies the installation process. The operator simply inserts the insert 4 into the pre-designed slot, then screws the locking nut 5 onto the fifth thread 402 and tightens it to complete the connection. Disassembly is the reverse process: unscrew the locking nut 5, pull out the insert 4, and the connectors can be easily separated. Compared to traditional welding or complex mechanical connections, this method significantly reduces the difficulty of installation and disassembly, saving time and labor costs.

[0053] By tightening the locking nut 5, the preload on the first connector 1, the second connector 2, and the third connector 3 can be flexibly adjusted. Different applications may have different requirements for the connection strength of the cable tray support, and this adjustable preload allows the cable tray support to adapt to various working conditions. The design of the plug 4 can accommodate different specifications of the first connector 1, the second connector 2, and the third connector 3. As long as the slot size is appropriate, regardless of the specific size and shape of the connector, the plug 4 and the locking nut 5 can be used for connection, improving the versatility of the cable tray support and reducing production and usage costs.

[0054] Furthermore, the first connector 1, the second connector 2, and the third connector 3 form a U-shaped clip 6, with at least two U-shaped clips 6, and also include a bracket 7, the bracket 7 having a wire-locking groove 701, a pressing member 8 pressing on the bracket 7, and a connecting steel member 9 for connecting to the outside. The U-shaped clip 6 is pressed onto the pressing member 8 and extends onto the connecting steel member 9.

[0055] In this embodiment, at least two U-shaped clamps 6 are composed of a first connector 1, a second connector 2, and a third connector 3, which can apply pressure to the pressure member 8 and the connecting steel member 9 from multiple directions. After the wire trough is placed in the wire slot 701 of the bracket 7, the U-shaped clamps 6 press against the pressure member 8 and extend to the connecting steel member 9. This multi-clamp arrangement enhances the fixing ability of the wire trough. Through the fastening action of the plug 4 and the locking nut 5, the U-shaped clamps 6 can maintain a stable clamping force, preventing the wire trough from shifting due to vibration, shaking, or external pulling, thus ensuring the stability and reliability of the wire trough installation.

[0056] Multiple U-shaped clips 6 are evenly distributed on the pressure member 8 and the connecting steel member 9, which can evenly distribute the weight and external force borne by the cable tray to each connection point. This avoids damage or deformation of components caused by excessive local pressure, extends the service life of the cable tray and the bracket 7, and also improves the safety of the entire cable tray system.

[0057] Because of the flexibility in the assembly of the U-shaped clips 6, they can be adjusted according to the size and shape of different cable trays. Whether the cable tray is wide or narrow, a stable fixation can be achieved through the proper arrangement of the U-shaped clips 6. Furthermore, this structure can also adapt to different types of connecting steel parts 9, enabling it to connect with various external structures and enhancing the versatility of the cable tray support in different application scenarios.

[0058] Multiple U-shaped clips 6 can be combined and installed according to actual needs to meet the installation requirements of different quantities and arrangements of cable trays. During installation, operators can flexibly adjust the position and quantity of U-shaped clips 6 according to the site conditions, improving installation efficiency and flexibility.

[0059] Furthermore, both the first connector 1 and the second connector 2 have a sixth threaded portion 103, which penetrates the connecting steel member 9 and also includes a fastening nut 10. The fastening nut 10 is threaded on the sixth threaded portion 103, and the fastening nut 10 and the bracket 7 are located on both sides of the connecting steel member 9, respectively.

[0060] In this embodiment, the sixth threaded portion 103 of the first connector 1 and the second connector 2 penetrates the connecting steel member 9 and is fixed by the fastening nut 10, forming tension on both sides of the connecting steel member 9. This double-sided fastening method greatly enhances the connection strength between the U-shaped clamp 6 and the connecting steel member 9. Compared with a single connection method, it can effectively resist the loosening or displacement of components caused by the weight of the cable tray, external vibration, or other external forces, ensuring the stability of the cable tray support during long-term use and guaranteeing the reliability of the cable tray installation.

[0061] By tightening the fastening nut 10, the relative position of the U-shaped clamp 6 and the connecting steel part 9 can be finely adjusted. During the installation of the cable tray bracket, the operator can precisely adjust the position of the U-shaped clamp 6 according to actual needs, ensuring the cable tray is accurately placed within the cable slot 701 of the bracket 7 and precisely aligned with the external structure. This precise adjustment function improves the installation accuracy of the cable tray bracket, meeting the requirements of different installation environments and usage.

[0062] Furthermore, the bracket 7 has a connecting section 702 and a supporting section 703, which are arranged vertically, and the U-shaped clip 6 is clipped onto the connecting section 702.

[0063] In this embodiment, the connecting section 702 and the supporting section 703 are arranged vertically, forming a stable right-angle structure. This structural design allows the bracket 7 to better distribute the forces from the cable tray and the U-shaped clamp 6. The U-shaped clamp 6 is engaged with the connecting section 702, and the weight of the cable tray is transferred to the connecting section 702 through the U-shaped clamp 6. Then, the vertical supporting section 703 evenly distributes the force to the mounting base, avoiding deformation or tilting of the bracket due to uneven force distribution, and greatly improving the overall stability and load-bearing capacity of the cable tray bracket.

[0064] The U-shaped clip 6 is secured to the connecting section 702, providing a clear positioning and operating interface for installation. During installation, operators can easily and accurately place the U-shaped clip 6 onto the connecting section 702, quickly completing the assembly process. Furthermore, the vertically positioned connecting section 702 and support section 703 make it easier for the bracket 7 to connect with other structural components during installation, such as walls and ceilings, reducing adjustment time and improving construction efficiency.

[0065] Furthermore, the end of the support section 703 has a limiting stop 704, and the middle of the support section 703 has a connecting hole 705.

[0066] In this embodiment, the limiting stop 704 is disposed at the end of the support section 703. During installation, it provides a clear positioning boundary for the bracket 7. When the bracket 7 contacts the mounting base (such as a wall or ground), the limiting stop 704 prevents the bracket 7 from sliding or shifting excessively, ensuring that the U-shaped clip 6 is accurately engaged on the connecting section 702, thereby ensuring the stable installation of the cable tray. For example, when installing the cable tray bracket on a wall, the limiting stop 704 can be tightly attached to the wall, keeping the bracket in a predetermined position and preventing uneven installation of the cable tray due to installation deviation.

[0067] For the U-shaped clip 6 and the cable tray, the limiting stop 704 helps maintain the relative positional accuracy between them. After installation, the limiting stop 704 can restrict the displacement of the cable tray in the direction of the support section 703, preventing the cable tray from sliding on the bracket due to external forces, and further improving the stability of the entire cable tray system.

[0068] Furthermore, the connecting section 702 is a square tube, and the thickness of the square tube is greater than the width of the supporting section 703.

[0069] In this embodiment, the connecting section 702 adopts a square tube structure, and the thickness of the square tube is greater than the width of the supporting section 703. This design greatly enhances the structural strength of the connecting section 702. The U-shaped clip 6 is clamped onto the connecting section 702. Due to the large thickness of the square tube, it can withstand greater pressure and friction transmitted from the U-shaped clip 6. In actual use, the cables in the cable tray will exert downward gravity and horizontal force on the U-shaped clip 6, which may be caused by vibration. The thick square tube connecting section 702 can effectively resist these external forces, prevent deformation or damage, ensure a stable connection between the U-shaped clip 6 and the connecting section 702, and thus ensure the stability of the cable tray installation.

[0070] The square tube structure itself has good resistance to torsion and compression. Combined with its large thickness, this greatly reduces the risk of deformation of the connecting section 702 when subjected to various complex external forces. Even under long-term loads from the weight of the cable tray and the influence of the external environment, it can maintain good shape and structural integrity, providing reliable support for the U-shaped clip 6 and the cable tray.

[0071] The thicker square tube connecting section 702 provides a wider operating space for the installation of the U-shaped clamp 6. Due to its greater thickness, the U-shaped clamp 6 is easier to align and engage during installation, and operators do not need to control the engagement position too precisely, reducing the difficulty of installation. At the same time, U-shaped clamps 6 of different specifications can be well adapted to the square tube connecting section 702 as long as their dimensions are within a certain range, improving the versatility and convenience of installation.

[0072] During installation, if the U-shaped clamp 6 on the square pipe connection section 702 needs to be repositioned or re-secured, the thicker pipe wall provides better grip and operation conditions. Operators can more easily tighten or loosen the U-shaped clamp 6, reducing the inconvenience and risk of damage caused by the thin pipe wall.

[0073] Furthermore, the longitudinal section of the support segment 703 is a triangular structure.

[0074] In this embodiment, when the longitudinal section of the support segment 703 is designed as a triangular structure, it can more effectively resist external forces from all directions. For example, when bearing the weight of the cable tray and potential lateral wind forces, vibrations, and other external forces, the triangular structure can evenly distribute these forces across the sides and corners, avoiding localized stress concentration and thus reducing the risk of deformation and damage. Compared to other cross-sectional shapes, the triangular structure allows the support segment 703 to maintain better shape and structural integrity under the same external forces, greatly improving the stability and reliability of the entire cable tray support.

[0075] Furthermore, it also includes anti-loosening washers 11, of which there are several, which are respectively disposed between the locking nut 5 and the third connecting member 3, and between the fastening nut 10 and the connecting steel member 9.

[0076] In this embodiment, in actual use scenarios, the cable tray support may be subjected to various vibrations and impacts, such as vibrations from the operation of surrounding machinery and equipment, or impacts from personnel walking. Anti-loosening washers 11 are respectively installed between the locking nut 5 and the third connecting piece 3, and between the fastening nut 10 and the connecting steel piece 9. Utilizing their unique elasticity and structural characteristics, they can absorb and buffer these vibration and impact energies. This prevents the locking nut 5 and the fastening nut 10 from loosening under vibration, ensuring that the connections between the U-shaped clamp 6, the connecting steel piece 9, and other components remain tight, thereby maintaining the stability of the entire cable tray support structure.

[0077] When a nut is tightened, it generates a preload, ensuring a reliable connection between the components. However, over time and due to external environmental factors, this preload may gradually decrease. The anti-loosening washer 11 continuously provides a certain amount of elastic pressure to the nut, compensating for the loss of preload caused by various factors, ensuring that the nut always maintains a suitable preload and guaranteeing the reliability and stability of the connection.

[0078] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
