Description

Technical Field

[0001] This utility model relates to the field of cable tray installation technology, and in particular to a cable tray connection component. Background Technology

[0002] Cable trays are devices used to support and protect cables, widely used in cable laying projects in the power, telecommunications, petroleum, and chemical industries. Their main function is to support cables by laying them on various building structures and pipe rack supports. Cable trays come in various configurations, such as trapezoidal, perforated trough, or solid-bottomed. Cable trays typically have long installation spans, and a complete cable tray is usually formed by splicing together multiple cable tray units with the same structure.

[0003] When two adjacent cable trays are joined together, a support plate is installed under both trays, and the main body of the tray is then locked to the support plate using bolt assemblies and other structures. Each tray body requires at least two sets of bolt assemblies for fixation to the support plate. This requires multiple tightening and loosening of the bolt assemblies during installation, resulting in low installation efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a cable tray connection component, which aims to solve the technical problems of multiple fixing points and low installation efficiency when the existing cable tray body is connected.

[0005] To achieve the above objectives, this utility model proposes a cable tray connection assembly, comprising: a support base for mounting a first cable tray and a second cable tray, wherein the joint between the first cable tray and the second cable tray is located on the top surface of the support base; a limiting plate slidably mounted on the support base, wherein two limiting plates are disposed opposite each other on the support base, and the joint between the first cable tray and the second cable tray is located between the two limiting plates; and an elastic element, wherein both ends of the elastic element are detachably mounted on the two limiting plates, and the elastic element is used to pull the two limiting plates closer together so that the two limiting plates abut against the sides of the first cable tray and the second cable tray.

[0006] Optionally, the elastic element includes a traction rope, a tension spring, and a first connecting part. Both ends of the traction rope are provided with tension springs, and the end of the tension spring away from the traction rope is connected to the first connecting part. The sidewalls of the two limiting plates that are far apart from each other are provided with second connecting parts, and the first connecting part and the second connecting part are detachably connected.

[0007] Optionally, a through groove is provided on the top of the limiting plate, through which the traction rope passes and abuts against the top wall of the first or second cable tray; the second connecting part is provided at the bottom of the side wall of the limiting plate.

[0008] Optionally, a first positioning protrusion is provided on the sidewalls of the limiting plates that are close to each other, and a first mounting hole is provided on the sidewalls of the first and second cable trays; when the limiting plate abuts against the sidewall of the first or second cable tray, the first positioning protrusion protrudes into the first mounting hole.

[0009] Optionally, the support includes a first mounting plate, on which a groove is formed along the width direction of the first and second cable trays; the bottom end face of the limiting plate is provided with a downwardly protruding guide portion, which is slidably installed in the groove.

[0010] Optionally, the top surface of the first mounting plate is provided with at least two second positioning protrusions along the length direction of the first and second cable trays; the bottom plates of the first and second cable trays are provided with second mounting holes, and when the first and second cable trays abut against each other on the top surface of the first mounting plate, the second positioning protrusions protrude into the corresponding second mounting holes.

[0011] Optionally, the support base also includes a second mounting plate for mounting the first mounting plate; the second mounting plate is vertically disposed on the bottom end surface of the first mounting plate; a reinforcing plate is also disposed between the first mounting plate and the second mounting plate, and the reinforcing plate is perpendicular to both the first mounting plate and the second mounting plate.

[0012] Optionally, the first mounting plate is made of conductive material and is also provided with a ground wire connector.

[0013] The cable tray connection assembly of this utility model features a support base beneath a first and second cable tray. Two limiting plates are slidably mounted on the support base, positioned on opposite sides of the first and second cable trays. An elastic element connects the first and second cable trays, causing the limiting plates to simultaneously approach and press against the first and second cable trays from both sides. This provides support for the first and second cable trays while simultaneously limiting their movement. In use, the first and second cable trays are placed on the top surface of the support base. One end of the elastic element is connected to one limiting plate, which is then passed through the first and second cable trays. Finally, the other end of the elastic element is connected to the other limiting plate. Under the tension of the elastic element, the two limiting plates approach each other and press against the side walls of the first and second cable trays, thus limiting their movement in the width direction. Compared with the prior art, this utility model uses the continuous traction force provided by the elastic element to make the limiting plate fit tightly against both sides of the cable tray. During installation, it is only necessary to install the two ends of the elastic element on the two limiting plates to limit the first and second cable trays. This makes disassembly and assembly more convenient and efficient. Attached Figure Description

[0031] This utility model proposes a cable tray connection assembly.

[0032] In the embodiments of this utility model, such as Figures 1-10 As shown, the cable tray connection assembly includes a support base 3, a limiting plate 4, and an elastic element 5. The support base 3 is used to install the first cable tray 1 and the second cable tray 2, and the joint of the first cable tray 1 and the second cable tray 2 is located on the top surface of the support base 3. The limiting plate 4 is slidably mounted on the support base 3, and two limiting plates 4 are arranged opposite each other on the support base 3. The joint of the first cable tray 1 and the second cable tray 2 is located between the two limiting plates 4. The two ends of the elastic element 5 are detachably mounted on the two limiting plates 4, and the elastic element 5 is used to pull the two limiting plates 4 closer to each other so that the two limiting plates 4 abut against the sides of the first cable tray 1 and the second cable tray 2.

[0033] Specifically, this invention features a support base 3 positioned below the first cable tray 1 and the second cable tray 2. Two limiting plates 4 are slidably mounted on the support base 3, respectively positioned on both sides of the first cable tray 1 and the second cable tray 2. An elastic element 5 connects the first cable tray 1 and the second cable tray 2 together, causing the elastic element 5 to drive the limiting plates 4 to simultaneously approach and press against the first cable tray 1 and the second cable tray 2 from both sides. This provides support for the first cable tray 1 and the second cable tray 2 while simultaneously limiting their movement. In use, the first cable tray 1 and the second cable tray 2 are placed on the top surface of the support base 3. One end of the elastic element 5 is connected to one limiting plate 4, and the elastic element 5 is passed through the first cable tray 1 and the second cable tray 2. Finally, the other end of the elastic element 5 is connected to the other limiting plate 4. Under the tension of the elastic element 5, the two limiting plates 4 approach each other and press against the side walls of the first cable tray 1 and the second cable tray 2, thus limiting the width of the first cable tray 1 and the second cable tray 2. Compared with the prior art, this utility model uses the continuous traction force provided by the elastic element 5 to make the limiting plate 4 fit tightly against both sides of the cable tray. During installation, it is only necessary to install the two ends of the elastic element 5 on the two limiting plates 4 to achieve the limiting of the first cable tray 1 and the second cable tray 2. The disassembly and assembly are more convenient and the disassembly and assembly efficiency is higher.

[0034] Optionally, the elastic element 5 includes a traction rope 51, a tension spring 52, and a first connecting part 53. Both ends of the traction rope 51 are provided with tension springs 52, and the end of the tension spring 52 away from the traction rope 51 is connected to the first connecting part 53. The side walls of the two limiting plates 4 that are far apart from each other are provided with second connecting parts 43, and the first connecting part 53 and the second connecting part 43 are detachably connected.

[0035] In this embodiment, the traction rope 51 is a flexible connector, such as a steel wire rope, nylon rope, or other rope with a certain strength and durability, used to connect and transmit traction force.

[0036] Optionally, the tension spring 52 generates traction force through elastic deformation. The first connecting part 53 is selected as a hook, buckle, or other detachable connecting structure; the second connecting part 43 is a ring structure, hook, or groove that matches the first connecting part 53 to achieve a detachable connection. For example, when the first connecting part 53 is a hook, the second connecting part 43 can be a ring structure, with the hook hanging on the ring to achieve connection; or when the first connecting part 53 is a buckle, the second connecting part 43 can be a groove, with the buckle engaging in the groove to achieve connection, thereby enabling the elastic element 5 to pull the limiting plate 4.

[0037] In this embodiment, the first connecting part 53 and the second connecting part 43 can be any commercially available elastic buckle assembly. The first connecting part 53 is the movable part of the elastic buckle assembly, and the second connecting part 43 is the fixed part of the elastic buckle assembly.

[0038] In this embodiment, the tension spring 52 and the traction rope 51, as well as the tension spring 52 and the first connecting part 53, are all fixedly connected.

[0039] In this embodiment, the traction rope 51 serves as a flexible connector, capable of adapting to the different widths of the first cable tray 1 and the second cable tray 2; the detachable connection between the first connecting part 53 and the second connecting part 43 makes the installation and disassembly of the elastic element 5 simple and quick, requiring no complex tools, thus improving the efficiency of installation and maintenance.

[0040] Optionally, the top of the limiting plate 4 is provided with a through groove 412, through which the traction rope 51 passes and abuts against the top wall of the first bridge frame 1 or the second bridge frame 2; the second connecting part 43 is provided at the bottom of the side wall of the limiting plate 4, so that there is a gap between the second connecting part 43 and the through groove 412, so that when the first connecting part 53 of the traction rope 51 is connected to the second connecting part 43, the tension spring 52 can be stretched to a greater extent, thereby increasing the traction force of the tension spring 52 on the two limiting plates 4.

[0041] Specifically, at least two elastic elements 5 are installed on the limiting plate 4 along its width direction. Correspondingly, at least two through slots 412 are formed on the limiting plate 4, which correspond to the first cable tray 1 and the second cable tray 2, respectively. In use, the first cable tray 1 and the second cable tray 2 are placed on the top surface of the support base 3. The first connecting part 53 of one end of the traction rope 51 is connected to the second connecting part 43 on a limiting plate 4. The traction rope 51 is passed through the through slot 412 and wraps around the top surface of the first cable tray 1 or the second cable tray 2. Finally, the first connecting part 53 of the other end of the traction rope 51 is connected to the second connecting part 43 of another limiting plate 4. Under the pulling force of the elastic elements 5, the two limiting plates 4 move closer to each other. At the same time, the two tension springs 52 cooperate with the traction rope 51 to form a downward pulling force on the top cover 13 of the cable tray 1 and the second cable tray 2. Thus, the entire first cable tray 1 and the second cable tray 2 form a downward pressure, which restricts the vertical movement of the first cable tray 1 and the second cable tray 2.

[0042] Optionally, the sidewalls of the limiting plates 4 that are close to each other are provided with a first positioning protrusion 41, and the sidewalls of the first cable tray 1 and the second cable tray 2 are both provided with a first mounting hole 121; when the limiting plate 4 abuts against the sidewall of the first cable tray 1 or the second cable tray 2, the first positioning protrusion 41 protrudes into the first mounting hole 121.

[0043] Specifically, the first cable tray 1 and the second cable tray 2 have several first mounting holes 121 on their side walls. These first mounting holes 121 allow the inner cavities of the first cable tray 1 and the second cable tray 2 to communicate with the outside, facilitating airflow and allowing for heat dissipation of the internal cables. When the limiting plate 4 abuts against the side wall of the first cable tray 1 or the second cable tray 2 under the traction of the elastic element 5, the first positioning protrusion 41 will embed into the corresponding first mounting hole 121. This interlocking design ensures precise positioning between the limiting plate 4 and the first cable tray 1 and the second cable tray 2, preventing misalignment during installation. Furthermore, the first positioning protrusion 41, once embedded in the first mounting hole 121, forms a mechanical lock, further preventing the cable tray from sliding or loosening under external forces (such as vibration or cable weight).

[0044] Specifically, the shape of the first positioning protrusion 41 can be cylindrical, rectangular, or other geometric shapes suitable for embedding in the through hole, and the side of the first positioning protrusion 41 near the side wall of the cable tray should be provided with a guide structure, such as a wedge-shaped surface or rounded corner treatment, so that the first positioning protrusion 41 can be more easily inserted into the first mounting hole 121.

[0045] In this embodiment, the length of the first positioning protrusion 41 is the same as the vertical dimension of the first mounting hole 121, so that after the first positioning protrusion 41 enters the first mounting hole 121, it can further restrict the vertical movement of the first cable tray 1 and the second cable tray 2.

[0046] Optionally, the support base 3 includes a first mounting plate 31, on which a groove 311 is provided along the width direction of the first cable tray 1 and the second cable tray 2; the bottom end face of the limiting plate 4 is provided with a downwardly protruding guide part 42, which is slidably installed in the groove 311.

[0047] In this embodiment, the guide part 42 is a cylindrical protrusion, and the bottom end of the guide part 42 is connected to the limiting end; the slide groove 311 penetrates the top and bottom surfaces of the support base 3, the guide part 42 passes through the slide groove 311, the limiting plate 4 is located above the slide groove 311, and the limiting end of the guide part 42 is located below the slide groove 311. The outer dimensions of the limiting end should be greater than the width of the slide groove 311, so that when the elastic element 5 pulls the two limiting plates 4, the two limiting plates 4 can only slide along the length direction of the slide groove 311.

[0048] Preferably, the bottom end of the guide portion 42 is provided with an external thread, and the limiting end is screwed into a nut on the external thread; after the limiting plate 4 moves into place, the nut can be tightened to further fix the first cable tray 1 and the second cable tray 2.

[0049] In this embodiment, the slide groove 311 does not exceed half of the length of the first mounting plate 31, and when one of the limiting plates 4 abuts the bottom of the slide groove 311, the other limiting plate 4 is still located in the slide groove 311 at the other end of the first mounting plate 31.

[0050] Optionally, the top surface of the first mounting plate 31 is provided with at least two second positioning protrusions 312 along the length direction of the first cable tray 1 and the second cable tray 2; the bottom plate 11 of the cable tray 1 and the second cable tray 2 are both provided with second mounting holes 111, and when the first cable tray 1 and the second cable tray 2 abut against each other, the second positioning protrusions 312 protrude into the corresponding second mounting holes 111.

[0051] In this embodiment, a second mounting hole 111 is provided on the base plate 11 of the first cable tray 1 and the second cable tray 2; the second positioning protrusion 312 is used to limit the first cable tray 1 and the second cable tray 2.

[0052] Specifically, the length of the second positioning protrusion 312 is the same as the length of the second mounting hole 111, so that after the second positioning protrusion 312 enters the second mounting hole 111, it can restrict the movement of the first cable tray 1 and the second cable tray 2 in the length direction.

[0053] Optionally, the support base 3 also includes a second mounting plate 32, which is used to mount the first mounting plate 31. The second mounting plate 32 is vertically disposed on the bottom end surface of the first mounting plate 31. A reinforcing plate 33 is also disposed between the first mounting plate 31 and the second mounting plate 32, and the reinforcing plate 33 is perpendicular to both the first mounting plate 31 and the second mounting plate 32.

[0054] Specifically, the second mounting plate 32 is used to connect with the wall or other environmental terrain to fix the entire support base 3; the reinforcing plate 33 is a right-angled triangular plate; the two right-angled sides of the reinforcing plate 33 are welded to the first mounting plate 31 and the second mounting plate 32 respectively. The reinforcing plate 33 effectively distributes the load borne by the first mounting plate 31 from the first cable tray 1, the second cable tray 2 and the cable, prevents stress concentration at the connection between the first mounting plate 31 and the second mounting plate 32, reduces the risk of bending or deformation of the first mounting plate 31, and extends the service life of the component.

[0055] Optionally, the first mounting plate 31 is made of conductive material, and a grounding connector 34 is also provided on the first mounting plate 31.

[0056] Specifically, in actual use, the first cable tray 1 and the second cable tray 2 used to carry cables ensure grounding and shielding effects to maintain good electrical continuity and prevent interference with the cables. Therefore, when the installation environment of the support plate has poor conductivity or is non-conductive, a grounding connector 34 should also be provided on the first mounting plate 31, and the grounding connector 34 should be grounded through a conductor to ensure good electrical continuity when the first cable tray 1 and the second cable tray 2 are installed on the support base 3.

[0057] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
