[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0031] In a preferred embodiment, see Figures 1 to 6 , the present application document provides a grid bridge 1, comprising: a first bridge body 10 and a second bridge body 20, the first bridge body 10 comprising a connecting portion 11, the second bridge body 20 comprising a portion to be connected 21, the first bridge body 10 and the second bridge body 20 are both composed of a plurality of longitudinal rods 30 and a plurality of curved transverse rods 40 staggered at intervals to form a bottom 50 and a side wing 60, and a connecting component 70 is protrudingly provided along the axial extension direction of the longitudinal rod 30 at the connecting portion 11 position of the first bridge body 10, and the connecting component 70 includes a bottom fastener 71; wherein, when the first bridge body 10 and the second bridge body 20 are connected, the connecting component 70 is connected to the portion to be connected 21 of the second bridge body 20, and the bottom fastener 71 is simultaneously fastened with the transverse rods 40 and the longitudinal rods 30 in the bottom 50.

[0032] The grid bridge 1 in the present application is suitable for supporting cables of different lengths, that is, a single first bridge body 10 or a single second bridge body 20 can support shorter cables, and when the first bridge body 10 and the second bridge body 20 are connected and assembled together through the connecting assembly 70, the grid bridge 1 formed can support longer cables. Similarly, the grid bridge 1 in the present application is not limited to the support length formed by the connection between the first bridge body 10 and the second bridge body 20. When it is necessary to support longer cables, the portion after the first bridge body 10 and the second bridge body 20 are connected can continue to be connected to a bridge body with the same structure as the first bridge body 10 through the connecting assembly 70 to extend the bridge support length.

[0033] Therefore, the present application document preferably provides a structure of a connecting component 70 to provide a grid bridge 1 using the connecting component 70 , so that the grid bridge 1 can more conveniently continuously extend the support length through the connecting component 70 .

[0034] It should be noted that the first bridge body 10 and the second bridge body 20 in this application document are both composed of multiple longitudinal rods 30 and multiple transverse rods 40 to provide the most basic support for the first bridge body 10 and the second bridge body 20. At the same time, a connecting component 70 is provided at the connection portion 11 of the first bridge body 10. Preferably, one end of the connecting component 70 is fixed to the connection portion 11 by welding or other means, see Figure 3 and Figure 4 The connecting assembly 70 is welded to the longitudinal rod body 30 through the metal rod body.

[0035] Furthermore, the protruding parts of the connecting assembly 70 include: side fastening parts 72. When the connecting assembly 70 is connected to the to-be-connected portion 21 of the second bridge frame body 20, the side fastening parts 72 are simultaneously fastened with the transverse rod body 40 and the longitudinal rod body 30 in the side wing 60.

[0036] As another preferred option, see Figure 4 and Figure 5 The bottom fastening member 71 includes: a first connecting arm 711, a second connecting arm 712 and an auxiliary connecting arm 713. The first connecting arm 711 and the second connecting arm 712 are connected by the auxiliary connecting arm 713. The first connecting arm 711 and the second connecting arm 712 are both fastened to the transverse rod body 40, and the auxiliary connecting arm 713 is against the longitudinal rod body 30.

[0037] Further preferably, the first connecting arm 711 and the second connecting arm 712 are both provided with a first concave surface 714 connected to the transverse rod body 40 . The first concave surface 714 is a quasi-circular structure, and the inner diameter of the first concave surface 714 is equal to the diameter of the transverse rod body 40 .

[0038] Further preferably, the auxiliary connecting arm 713 abuts against the longitudinal rod body 30, and the auxiliary connecting arm 713 is connected to the first connecting arm 711 and the second connecting arm 712 in an arc-shaped transition, so that the auxiliary connecting arm 713 protrudes relative to the first connecting arm 711 and the second connecting arm 712. The auxiliary connecting arm 713 is set to stop and prevent the first bridge frame body 10 from continuing to move downward when connected relative to the second bridge frame body 20, and the first connecting arm 711 and the second connecting arm 712 are both in the same plane with the longitudinal rod body 30, so that the bottom fastener 71 can provide a certain support effect on the grid bridge frame 1.

[0039] It should be noted that the span between the first connecting arm 711 and the second connecting arm 712 is relatively large, and a longitudinal rod 30 is sandwiched between the first connecting arm 711 and the second connecting arm 712. There are three longitudinal rods 30 located at the bottom 50. The span between the first connecting arm 711 and the second connecting arm 712 is roughly equal to the span of the three longitudinal rods 30 at the bottom 50. Therefore, the first connecting arm 711 and the second connecting arm 712 cooperate with the auxiliary connecting arm 713 to further improve the stability of the connection between the bottom fastener 71 and the part to be connected 21.

[0040] Preferably, both ends of the transverse rod 40 are bent to match the longitudinal rod 30 to form two oppositely disposed side wings 60, see Figure 5 The side fastener 72 includes: a first side fastener 721 and a second side fastener 722. The first side fastener 721 and the second side fastener 722 have the same structure, and the first side fastener 721 and the second side fastener 722 are mirror-imaged. The first side fastener 721 is connected to the side wing 60 at one end, and the second side fastener 722 is connected to the side wing 60 at the other end. The first side fastener 721 and the second side fastener 722 have the same structure and the fastening steps are also the same. Therefore, the following embodiment is described by taking the side fastener 72 on one side as an example.

[0041] Further preferably, the side fastening piece 72 includes: a first side connecting arm 723, the first side connecting arm 723 is provided with a second concave surface 7231, and the second concave surface 7231 is engaged with the transverse rod body 40 at the position of the side wing 60, and the inner diameter of the second concave surface 7231 is roughly equal to the diameter of the transverse rod body 40 to improve the fastening stability.

[0042] Further preferably, the side fastener 72 also includes: a second side connecting arm 724, the first side connecting arm 723 is connected to the second side connecting arm 724, and the second side connecting arm 724 is arranged on the same side as the first side connecting arm 723, and the first side connecting arm 723 cooperates with the second side connecting arm 724 to engage with the transverse rod body 40.

[0043] Further preferably, the side fastener 72 further includes: an arcuate connecting section 725, through which the first side connecting arm 723 and the second side connecting arm 724 are transitionally connected; the longitudinal rod body 30 at the side wing 60 is distributed with a first longitudinal rod 31 and a second longitudinal rod 32, the first longitudinal rod 31 and the second longitudinal rod 32 are arranged parallel to each other, one end of the arcuate connecting section 725 is tangent to the side of the first longitudinal rod 31 close to the bottom surface, and the other end extends to the side of the second longitudinal rod 32 close to the bottom surface, see Figure 5 The side fastener 72 is arranged in a "Z"-shaped structure, and the two ends of the arc-shaped connecting section 725 are staggered relative to the longitudinal rod body 30, so that the arc-shaped connecting section 725 can cooperate with the first side connecting arm 723 and the second side connecting arm 724 to assist in clamping the first longitudinal rod 31 and the second longitudinal rod 32, thereby improving the connection stability of the side fastener 72.

[0044] Preferably, see Figure 6 The second side connecting arm 724 is also provided with a horizontal section 726, which is protruding toward the axial direction of the longitudinal rod body 30 and relative to the first bridge frame body 10. The end of the horizontal section 726 is connected to the first side connecting arm 723 through the arc-shaped connecting section 725, so that the arc-shaped connecting section 725 is inclined, expanding and extending the connection node position of the arc-shaped connecting section 725 and the second longitudinal rod 32, and at the same time, the deformation range of the arc-shaped connecting section 725 can be increased to a certain extent, which is convenient for disassembly and assembly.

[0045] Among them, the process of assembling the first bridge body 10 and the second bridge body 20 through the connecting assembly 70 is as follows: the end to be connected of the second bridge body 20 is only distributed with the longitudinal rod 30 and the transverse rod 40. During assembly, the first concave surface 714 in the bottom fastener 71 is aligned with the bottom 50 area of ​​the transverse rod 40, and the second concave surface 7231 in the side fastener 72 is aligned with the transverse rod 40 in the side wing 60 area. The connecting assembly 70 moves along the vertical direction toward the to-be-connected portion 21 of the second bridge body 20. At this time, when the arc-shaped connecting section 725 contacts the first longitudinal rod 31, it drives the first side connecting arm 72 The second side connecting arm 724 undergoes a certain elastic deformation with the second side connecting arm 724, thereby enabling the second concave surface 7231 of the side fastener 72 to be fitted into the transverse rod body 40 in the area of ​​the side wing 60. The arcuate connecting segment 725 is reset by elastic deformation, so that the arcuate connecting segment 725 is tangent to the first longitudinal rod 31, and the horizontal segment 726 of the second side connecting arm 724 is tangent to the transverse rod body 40. The horizontal segment 726 is located at the lower position of the second longitudinal rod 32, which extends the length of the arcuate connecting segment 725 to a certain extent, increases the deformability of the arcuate connecting segment 725, and facilitates the engagement and assembly of the connecting assembly 70 with the portion to be connected 21.

[0046] The bottom fastener 71 completes the fastening operation along with the fastening of the side fastener 72, and the first concave surface 714 is embedded in the transverse rod 40 at the bottom 50 position to complete the assembly, so as to fix the bottom 50 of the first bridge body 10 and the bottom 50 of the second bridge body 20 in the same plane, ensuring the effective passage of the cable.

[0047] Also, see Figure 7 , provides another implementation structure of the connecting component 70, in which a straight long side 727 is extended between the arc-shaped connecting section 725 and the first side connecting arm 723, and the straight long side 727 and the first side connecting arm 723 are arranged in the same plane. The setting of the straight long side 727 can further improve the stability of the fit between the arc-shaped connecting section 725 and the first longitudinal rod 31.
