Description

Technical Field

[0001] The utility model relates to the technical field of cable bridge devices, and particularly relates to a locking structure for a trough-type cable bridge. Background Art

[0002] A cable bridge is a metal or non-metal structural system used to support and fix communication or power cables such as cables, wires, and optical fibers. The cable bridge is used to adapt to different wiring requirements and environmental conditions, and has good mechanical strength, corrosion resistance, and installation convenience. It can be used to meet complex wiring requirements and is widely used in places such as data centers, communication machine rooms, industrial factories, and commercial buildings, and is an important infrastructure in modern communication and power systems.

[0003] As one type of them, the trough-type cable bridge is widely used in various engineering projects due to its simple structure and low cost. However, in the actual use process, the trough-type cable bridge usually includes a plurality of trough-type bridge units arranged along the length direction of the cable. The adjacent trough-type bridge units need to be fixed through connecting pieces. Traditional connection methods use fasteners such as bolts and screws for assembly connection, but these connection methods are prone to problems such as structural loosening and unstable locking structures during long-term use. These problems may cause displacement, deformation, or even damage to the cable bridge during long-term use, affecting the stability and safety of the trough-type cable bridge. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a locking structure for a trough-type cable bridge, which is used to provide a stable connection method between adjacent trough-type bridge units to ensure the assembly performance of the trough-type cable bridge while ensuring its stability and safety during long-term use.

[0005] The technical problem solved by the utility model is realized by adopting the following technical solutions:

[0006] A locking structure for a trough-type cable bridge, including a supporting bracket;

[0007] The supporting bracket includes a structural bracket, the structural bracket is integrally U-shaped, including vertical arm rods formed on both sides and a cross brace connected to the base of the vertical arm rods; a flat lining plate is also formed on the surface of the cross brace of the supporting bracket;

[0008] Assembly structures are formed on the upper parts of the vertical arm rods on both sides. A retaining link is hinged on the assembly structure of one vertical arm rod, and a fixed buckle for clamping the outer end of the retaining link is formed on the assembly structure of the other vertical arm rod;

[0009] The supporting bracket uses a flat lining plate as the placement plane of the trough cable tray unit. After the trough cable tray unit is placed on the flat lining plate, a retaining connecting rod is used to buckle on the surface of the trough cable tray unit from above.

[0010] As a further limitation, the vertical arm rod and the cross brace of the structural support are formed by bending the same steel structure rod, and the size of the U-shaped structure formed by combining the vertical arm rods and the cross brace on both sides is the same as the cross-sectional size of the trough cable tray unit.

[0012] As a further limitation, the cross brace is a rod with a rectangular cross section, the long side of the cross section of the rectangular cross-section rod is used as the setting surface of the flat lining plate, and the flat lining plate is a detachable structure on the cross brace.

[0013] As a further limitation, a rubber lining layer is formed on the surface of the flat lining plate, and anti-slip patterns are formed on the surface of the rubber lining layer.

[0014] As a further limitation, the trough cable tray units for assembly on the supporting bracket have matching stepped surface overlapping parts at the outer edges on both sides, and the trough cable tray units have notch grooves matching the size of the retaining connecting rod at the stepped surface overlapping parts;

[0020] In order to make the technical means, creative features, achieved purposes and functions implemented by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific drawings.

[0021] Refer to Figure 1 A preferred embodiment of a locking structure for a trough-shaped cable tray. In this embodiment, the main structure of the locking structure for the trough-shaped cable tray is a support bracket, which is composed of a detachable vertical arm rod 12, a cross brace 9 and a flat lining plate 8, and also includes a suspension rod 1 and a retaining connecting rod 5 as structural accessories.

[0022] The above structural components adopt a standardized production process during production to ensure the dimensional accuracy and assembly consistency of each component. During use, each structural component is transported to the construction site for assembly and use.

[0023] In this embodiment, an assembly structure body 2 is formed on the upper part of the vertical arm rod 12, and an insertion part 10 bent at a right angle is formed on the lower part. The cross section of the insertion part 10 is rectangular, and a through hole is formed in the insertion part 10; the cross brace 9 is a hollow rectangular rod, having an end face insertion hole matching the insertion part 10, and another through hole matching the aforementioned through hole is formed on the side wall of the rod body inside the end face insertion hole. The vertical arm rod 12 is connected to the cross brace 9 through the insertion part 10 in the style as shown in Figure 1 and is fixed in shape by inserting a retaining screw 11 into the corresponding through holes for assembly to form a U-shaped structure body.

[0024] After the corresponding cross brace 9 is fixed in position, the long side of its rectangular cross section is the upper surface, and the flat lining plate 8 is connected to the cross brace 9 through a threaded assembly structure or a snap connection structure, which is convenient for disassembly and replacement.

[0025] In this embodiment, the detachable assembly method of the cross brace 9 and the vertical arm rod 12 is not limited to the insertion structure, but also includes a threaded assembly structure and a snap connection structure to adapt to different installation environments and requirements. For example, when installation needs to be carried out in a narrow space, the threaded assembly structure can provide a more compact connection method, while the snap connection structure can achieve quick disassembly and reorganization.

[0026] In addition, in other embodiments, in order to reduce the molding cost, the cross strut 9 and the vertical arm 12 can also be integrally formed, that is, the vertical arm and the cross strut of the structure support are formed by bending the same steel structure rod. This molding method has higher production efficiency and lower material cost. On the premise of ensuring strength and stability, the integrally formed structure support simplifies the production process, reduces the assembly link, and further shortens the production cycle.

[0027] The inner surface of the planar liner 8 is the assembly area of the channel cable tray. The channel cable tray applied to the assembly on the locking structure is formed by butt-jointing multiple channel tray units end to end. Each single channel tray unit includes matching step surface overlapping parts at both ends, so that two adjacent channel tray units can be stacked at the step surface overlapping parts. Specifically in this embodiment, the inner step of the first channel tray unit 1 can be stacked on the outer step structure of the second channel tray unit 2 in the style shown as Figure 1 shown to form a butt-joint structure end to end. This butt-joint position is the connection part of the channel tray units and can be placed between the two vertical arms 12 on the surface of the planar liner 8.

[0028] In addition, the first channel tray unit 1 and the second channel tray unit 2 are formed with matching notch grooves 4 at the position of the step surface overlapping part, so that during the butt-joint process of the first channel tray unit 1 and the second channel tray unit 2 at the step surface overlapping part, the notch grooves 4 of the two channel tray units will coincide to form an open notch, which is convenient for the insertion and fixation of the retaining link 5.

[0029] The retaining link 5 is a detachable structure formed on the assembly structure 2. Correspondingly, a hinge 3 is formed on the assembly structure 2 at the top of one side vertical arm 12, and one end of the retaining link 5 is integrally connected with this hinge 3. A fixed buckle 12 is formed on the assembly structure 2 at the top of the other side vertical arm 12. When the first channel tray unit 6 and the second channel tray unit 7 are placed on the planar liner 8 and the butt-joint is completed, the retaining link 5 is buckled on the surface of the channel tray unit from above, and the fixed buckle 13 fixes its position at the outer end of the retaining link 5, so that the retaining link 5 in the position-fixed state is clamped into the notch grooves 4 on both sides at the middle position, thereby realizing the stable connection between the channel tray units.

[0030] In this embodiment, by changing the dimensions of the vertical arm 12 and / or the cross strut 9 and matching the retaining link 5 with the corresponding length, the adaptive matching of channel tray units with different dimensions can be achieved.

[0031] In order to ensure the structural stability of the first trough-type bridge unit 6 and the second trough-type bridge unit 7 at the docking part in the docking state, an anti-slip structure such as a rubber lining layer can also be formed on the surface of the flat lining plate 8. Through the good anti-slip performance of the surface, the anti-slip structure can cooperate with the position fixation of the retaining link 5 at the notch groove 4 to effectively prevent the trough-type bridge unit from sliding on the support bracket, ensuring the stability of the trough-type cable bridge system.

[0032] In addition, mounting holes for mounting the hanging rod 1 are formed on the assembly structure 2 to facilitate the hanging and position adjustment of the trough-type bridge unit during the installation process.

[0033] In summary, the locking structure of the present utility model not only improves the installation efficiency and stability of the trough-type cable bridge, but also reduces the maintenance cost, ensures the safe operation of the cable, and has significant technical advantages and application values.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model.

In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
