Description

Technical Field

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

[0002] Cable trays are rigid structural systems used to support and protect cables, mainly composed of straight sections, bends, accessories, and supports. The original design purpose of cable trays was to replace traditional welded steel supports, offering better cable protection, reduced interference, fire resistance, and ease of installation while maintaining an aesthetically pleasing appearance. Common structures include tray-type cable trays, ladder-type cable trays, and trough-type cable trays, and are typically made of steel, aluminum alloy, or fiberglass.

[0003] The ladder-type cable tray assembly structure typically consists of horizontal beams (ladders) and vertical side plates, allowing for flexible adjustment of support height and position to adapt to different needs and site conditions. When assembling the beams and side plates, welding or bolting is generally used. After aligning the two ends of the beam with the side plates, external tools are required to achieve the connection, making the installation process cumbersome for operators and reducing the installation efficiency of the cable tray structure. Utility Model Content

[0004] The purpose of this invention is to provide an assembled and connected cable tray structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable tray structure for assembly and connection includes symmetrically and parallelly arranged side plates, with multiple crossbeams arranged along the length direction between the two side plates. The two ends of the crossbeams are detachably installed to the side plates, and multiple connecting frames are provided on the side plates. The ends of the crossbeams can be inserted into the connecting frames.

[0007] Symmetrically arranged limiting components are installed within the connecting frame, and the limiting components can be inserted into the locking groove formed at the end of the crossbeam;

[0008] An unlocking mechanism, installed within the connecting frame, can compress the limiting component to resolve the limitation of the limiting component on the end of the crossbeam.

[0009] The cable tray structure assembled and connected as described above: the ends of the crossbeams are symmetrically formed with compression sections arranged in an inclined structure.

[0010] As described above, the cable tray structure is assembled and connected as follows: the limiting component includes a locking plate, and the connecting frame is symmetrically formed with embedded grooves. One end of the locking plate is slidably disposed in the embedded groove, and the other end passes through the embedded groove and can be inserted into the locking groove. The end of the locking plate located in the embedded groove can abut against the limiting plate slidably installed in the embedded groove.

[0011] It also includes a second spring, which is disposed in the inner groove. One end of the second spring abuts against the limiting plate, and the other end abuts against the side wall of the inner groove.

[0012] As described above, the cable tray structure is assembled and connected as follows: a first inclined surface adapted to the pressing part is formed on one end of the locking plate, and a second inclined surface is formed on the other end. The second inclined surface abuts against a fourth inclined surface formed on the limiting plate.

[0013] As described above, the cable tray structure is assembled and connected as follows: the unlocking mechanism includes an unlocking plate that is slidably disposed in the inner groove. A third inclined surface is formed on one end of the unlocking plate near the locking plate. The third inclined surface can be inserted into the sliding groove formed by the locking plate and squeeze the sliding groove. A first spring is fixedly connected to the other end. The end of the first spring away from the unlocking plate is fixedly connected to the side wall of the inner groove.

[0014] It also includes a push plate, which is fixed to the unlocking plate and can slide through the connecting frame and be connected to the connecting frame.

[0015] As described above, in the assembled bridge structure, when the unlocking plate slides, the limiting plate is driven to separate from the locking plate by a connecting rod assembly provided in the inner groove.

[0016] The cable tray structure assembled as described above: the connecting rod assembly includes a hinged column fixedly installed in the embedded groove, a connecting rod rotatably installed on the hinged column, one end of the connecting rod being able to abut against a second protrusion fixedly installed on the limiting plate, and the other end being able to abut against a first protrusion fixedly installed on the unlocking plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] When assembling the side panels and crossbeams, both ends of the crossbeams are inserted into the connecting frames. When the crossbeams are inserted, they exert pressure on the limiting components, causing the limiting components to make way for the insertion of the crossbeams. Once the crossbeams are fully inserted, the limiting components lose pressure and insert into the locking grooves. With the cooperation of the connecting frames and the limiting components, a stable connection between the crossbeams and the side panels is ensured, and no external auxiliary tools are needed, which can effectively improve the assembly efficiency of the cable tray structure.

[0019] Meanwhile, when the connecting frame and the crossbeam are disassembled, in order to avoid excessive friction between the limiting component and the crossbeam, which would prevent the limiting component from separating from the crossbeam, the unlocking mechanism is driven to squeeze the limiting component to separate the limiting component from the crossbeam. When the limiting component locks the crossbeam, its movement does not affect the unlocking structure. Attached Figure Description

[0027] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1-6 In this embodiment of the utility model, an assembled and connected cable tray structure includes symmetrically and parallelly arranged side plates 1, and a plurality of crossbeams 2 are arranged between the two side plates 1 along the length direction. The two ends of the crossbeams 2 are respectively detachably installed to the side plates 1. A plurality of connecting frames 3 are arranged on the side plates 1, and the ends of the crossbeams 2 can be inserted into the connecting frames 3.

[0031] Symmetrically arranged limiting components are installed within the connecting frame 3, and the limiting components can be inserted into the locking groove 202 formed at the end of the crossbeam 2;

[0032] The unlocking mechanism, installed within the connecting frame 3, can compress the limiting component to resolve the limitation of the limiting component on the end of the crossbeam 2.

[0033] In this embodiment, when the side plate 1 and the crossbeam 2 are assembled, both ends of the crossbeam 2 are inserted into the connecting frame 3 respectively. When the crossbeam 2 is inserted, it squeezes the limiting component, causing the limiting component to give way to the insertion of the crossbeam 2. After the crossbeam 2 is fully inserted, the limiting component loses its squeezing and inserts into the locking groove 202. With the cooperation of the connecting frame 3 and the limiting component, the stable connection between the crossbeam 2 and the side plate 1 is ensured, and no external auxiliary tools are needed, which can effectively improve the assembly efficiency of the cable tray structure.

[0034] Meanwhile, when the connecting frame 3 is disassembled from the crossbeam 2, in order to avoid excessive friction between the limiting component and the crossbeam 2, which would prevent the limiting component from separating from the crossbeam 2, the unlocking mechanism is driven to squeeze the limiting component to achieve separation of the limiting component from the crossbeam 2. When the limiting component locks the crossbeam 2, its movement does not affect the unlocking structure.

[0035] Preferably, the ends of the crossbeam 2 are symmetrically formed with an inclined compression section 201.

[0036] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The limiting component includes a locking plate 4. The connecting frame 3 has symmetrically formed inner grooves 301. One end of the locking plate 4 is slidably disposed in the inner groove 301, and the other end passes through the inner groove 301 and can be inserted into the locking groove 202. The end of the locking plate 4 located in the inner groove 301 can abut against the limiting plate 6 slidably installed in the inner groove 301.

[0037] It also includes a second spring 10, which is disposed in the inner groove 301. One end of the second spring 10 abuts against the limiting plate 6, and the other end abuts against the side wall of the inner groove 301.

[0038] One end of the locking plate 4 has a first inclined surface 401 adapted to the pressing part 201, and the other end has a second inclined surface 402. The second inclined surface 402 abuts against the fourth inclined surface 601 formed on the limiting plate 6.

[0039] Specifically, when the end of the crossbeam 2 is inserted into the connecting frame 3, the pressing part 201 on it moves to abut against the first inclined surface 401. The crossbeam 2 continues to move and can generate an inclined force on the first inclined surface 401, so that the locking plate 4 is pressed and moves towards the inner groove 301. At this time, the locking plate 4 makes way for the insertion of the crossbeam 2. At the same time, the second inclined surface 402 presses against the fourth inclined surface 601, so that the limiting plate 6 makes way for the movement of the locking plate 4, and the second spring 10 is further compressed to store elastic potential energy until the crossbeam 2 is completely inserted into the connecting frame 3. After the locking plate 4 loses the pressing of the crossbeam 2, under the elastic action of the second spring 10, the locking plate 4 resets and is inserted into the locking groove 202. The plane on the locking plate 4 abuts against the plane on the locking groove 202 to realize the locking work of the connecting frame 3 on the crossbeam 2, ensuring the stable connection between the crossbeam 2 and the side plate 1.

[0040] It should be noted that when the locking plate 4 completely yields to the crossbeam 2, the second inclined surface 402 and the fourth inclined surface 601 are still partially in contact, so that after the locking plate 4 loses the pressure of the crossbeam 2, the fourth inclined surface 601 can squeeze the second inclined surface 402 under the elastic action of the second spring 10.

[0041] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The unlocking mechanism includes an unlocking plate 5 slidably disposed in the inner groove 301. A third inclined surface 501 is formed on one end of the unlocking plate 5 near the locking plate 4. The third inclined surface 501 can be inserted into the sliding groove 403 formed by the locking plate 4 and squeeze the sliding groove 403. A first spring 9 is fixedly connected to the other end. The end of the first spring 9 away from the unlocking plate 5 is fixedly connected to the side wall of the inner groove 301.

[0042] It also includes a push plate 8, which is fixed to the unlocking plate 5 and can slide through the connecting frame 3 and be connected to the connecting frame 3.

[0043] When the unlocking plate 5 slides, the limiting plate 6 is driven to separate from the locking plate 4 by the connecting rod assembly provided in the inner groove 301.

[0044] The connecting rod assembly includes a hinged post 7 fixedly installed in the inner groove 301, and a connecting rod 11 is rotatably installed on the hinged post 7. One end of the connecting rod 11 can abut against the second protrusion 602 fixedly installed on the limiting plate 6, and the other end can abut against the first protrusion 502 fixedly installed on the unlocking plate 5.

[0045] In detail, when the crossbeam 2 separates from the side plate 1, the push plate 8 is driven to move toward the locking plate 4, so that the unlocking plate 5 is inserted into the slide groove 403. After the third inclined surface 501 abuts against the inclined surface on the slide groove 403, under the pressure of the unlocking plate 5, the locking plate 4 can overcome the elastic force of the second spring 10 and exit from the locking groove 202, thus unlocking the locking plate 4's locking work on the crossbeam 2, thereby quickly and completely disassembling the crossbeam 2 from the side plate 1.

[0046] When the unlocking plate 5 moves, the first spring 9 is stretched to store elastic potential energy. The first protrusion 502 on the unlocking plate 5 compresses one end of the connecting rod 11, causing the connecting rod 11 to deflect around the hinge post 7. The deflection of the other end of the connecting rod 11 generates a counterforce on the second protrusion 602, thereby releasing the limiting plate 6 from the locking plate 4. At the same time, when the locking plate 4 locks the crossbeam 2, the reciprocating movement of the limiting plate 6 does not affect the second protrusion 602, thus effectively improving the disassembly efficiency of the cable tray structure.

[0047] The locking plate 4 is pressed by the unlocking plate 5 instead of being unlocked by the limiting plate 6 directly. Under the action of the connecting rod 11, the effort-saving effect is achieved.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
