Specific embodiments

[0023] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model rather than limiting it.

[0024] The following will be further described in detail with reference to the attached Figures 1-6 This embodiment will be further described in detail.

[0025] Please refer to Figures 1-6 , a sheet metal connecting piece in this embodiment is used for butt - joint connection between two cable trays 10. It includes a plate body 100. Both ends of the plate body 100 are bent to form a connecting part 110. A cavity is enclosed between the plate body 100 and the connecting part 110. Buckling ends 120 are oppositely arranged on the outer side of the connecting part 110 and on both sides. As Figures 2-3 shown, when it is used for butt - joint connection of the cable trays 10, both sides of this sheet metal connecting piece are respectively inserted into the inner sides of two butt - joint cable trays 10. Among them, buckling grooves 301 that cooperate with the corresponding buckling ends 120 are provided on the opposite side walls of the cable trays 10. When the sheet metal connecting piece is inserted into the inner side of the cable tray 10, the buckling ends 120 can be buckled into the corresponding buckling grooves 301, which can realize the butt - joint of the cable trays 10 by this sheet metal connecting piece. At the same time, using this sheet metal connecting piece to connect the cable trays 10 makes it only necessary to remove this sheet metal connecting piece when maintaining and overhauling the cables in the cable trays 10, without having to remove the entire cable tray 10, making the maintenance and overhaul operations simple and convenient.

[0026] It should be noted that the connecting portion 110 is disposed at a 90° angle with respect to the plate body 100. When the sheet metal connector is inserted into the inner side of the cable tray 10, the plate body 100 abuts against the bottom wall of the cable tray 10, and the connecting portion 110 abuts against the corresponding side wall of the cable tray 10, so that the connecting portion 110 can support the side wall of the cable tray 10. Through the setting of the concave cavity, the normal use of the cable tray 10 after docking is ensured;

[0027] Among them, in order to improve the connection strength of the sheet metal connector to the cable tray 10, that is, to improve the strength of the connecting portion 110 to support the side wall of the cable tray 10, a detachable first reinforcing plate 130 is provided between the plate body 100 and the connecting portion 110 and is located in the concave cavity. Among them, the first reinforcing plate 130 is triangular, and the two side walls of the first reinforcing plate 130 respectively abut against the plate body 100 and the corresponding connecting portion 110. Thus, the strength of the connecting portion 110 can be improved, facilitating the actual use of the sheet metal connector.

[0028] In this embodiment, as Figure 4 shown, the plate bodies 100 can be spliced by connectors. Thus, when the distance between two cable trays 10 is relatively far and it is impossible to connect with a single plate body 100, the plate bodies 100 are spliced by connectors to produce a sheet metal connector of a larger specification, so as to meet the butt joint connection between the two cable trays 10 in this case.

[0029] In this embodiment, the buckling end 120 includes folding plates 121 that are bent and disposed on both sides of the upper end of the connecting portion 110. A buckling groove 122 is formed between the folding plates 121 and the connecting portion 110. First mounting holes 111 are oppositely provided on both sides of the connecting portion 110. Second mounting holes 123 are provided on the folding plates 121 corresponding to the first mounting holes 111. The buckling of the buckling end 120 is achieved by connecting the corresponding first mounting holes 111 and second mounting holes 123 with a first bolt 210.

[0030] When this embodiment is actually used, when the sheet metal connector is inserted into the inner side of the cable tray 10, the folding plates 121 are buckled in the corresponding buckling grooves 301. Among them, through holes 302 are provided on the side wall of the cable tray 10 and are oppositely disposed with the corresponding first mounting holes 111 and second mounting holes 123. Thus, the buckling end 120 is fixed on the cable tray 10 by the first bolt 210 passing through the corresponding first mounting hole 111, second mounting hole 123, and through hole 302, so that the sheet metal connector can be used for butt joint between two cable trays 10 and is convenient for disassembly.

[0031] In this embodiment, corresponding to the first reinforcing plate 130 on the plate body 100, there are first threaded holes 101 provided oppositely, and corresponding to the first reinforcing plate 130 on the connecting portion 110, there are second threaded holes 112 provided oppositely. The first reinforcing plate 130 is fixed in the concave cavity respectively by countersunk head screws 140 passing through the corresponding first threaded holes 101 and second threaded holes 112.

[0032] In this embodiment, by placing the first reinforcing plate 130 at the bent portion of the plate body 100, the two side walls of the first reinforcing plate 130 are respectively attached to the plate body 100 and the corresponding connecting portion 110. Among them, threaded blind holes corresponding to the first threaded holes 101 and the second threaded holes 112 are respectively provided on the two side walls of the first reinforcing plate 130. By threading the countersunk head screws 140 through the first threaded holes 101 and the second threaded holes 112 respectively into the corresponding threaded blind holes, the fixing of the first reinforcing plate 130 in the concave cavity can be realized, and it is convenient for disassembly.

[0033] Combined Figure 5 and Figure 6 As shown, in this embodiment, on the plate body 100 and at the two sides, there are first fixing holes 102 provided oppositely, and on the connecting portion 110, there are second fixing holes 113 provided oppositely at the two sides;

[0034] The connecting member includes a connecting plate 510 which is L-shaped and is relatively arranged in the concave cavity. When the plate bodies 100 are butted, one side wall of the connecting plate 510 is attached to the plate body 100, and the other side wall is attached to the corresponding connecting portion 110. A first through hole 601 corresponding to the corresponding first fixing hole 102 is opened on one side wall of the connecting plate 510, and a second through hole 602 corresponding to the corresponding second fixing hole 113 is opened on the other side wall. The first fixing hole 102 and the corresponding first through hole 601, and the second fixing hole 113 and the corresponding second through hole 602 are connected by a second bolt 500 to realize the fixed connection of the connecting plate 510 to the butted plate bodies 100.

[0035] In this embodiment, when the plate bodies 100 are spliced, their opposite side walls are abutted and close to each other. At this time, the connecting member is used to connect the two plate bodies 100 at the bent portion of the plate body 100, so as to realize the splicing of the plate bodies 100;

[0036] In actual use, by threading the second bolt 500 through the first fixing hole 102 and the corresponding first through hole 601, and the second fixing hole 113 and the corresponding second through hole 602, the fixing of the connecting plate 510 at the bent portion of the plate body 100 can be realized, and it is convenient for disassembly;

[0037] Among them, in order to improve the strength of the connecting plate 510 during the splicing of the plate body 100, second reinforcing plates 520 for supporting the connecting plate 510 are relatively arranged on both sides of the connecting plate 510. Among them, the second reinforcing plates 520 are triangular, and their two side walls are fixed to the connecting plate 510 by welding to improve the structural strength of the connecting plate 510.

[0038] In this embodiment, first sliding grooves 103 are relatively arranged on the side surface of the plate body 100 located in the concave cavity and on both sides, and second sliding grooves 114 are relatively arranged on the side surface of the connecting portion 110 located in the concave cavity and on both sides. First sliders 611 and second sliders 612 that are respectively snapped into the first sliding grooves 103 and the second sliding grooves 114 are arranged on the connecting plate 510.

[0039] During the actual use of this embodiment, the first sliding grooves 103 are arranged along the extending direction of the plate body 100, the second sliding grooves 114 are arranged along the extending direction of the connecting portion 110, and the first sliding grooves 103 and the corresponding second sliding grooves 114 are arranged in communication with each other;

[0040] Among them, by respectively snapping the first sliders 611 and the second sliders 612 on the corresponding sides of the connecting plate 510 into the corresponding first sliding grooves 103 and the second sliding grooves 114, when the connecting plate 510 is used for splicing between the plate bodies 100, the spliced plate bodies 100 are not easily separated along their butting direction, thereby improving the connection strength between the plate bodies 100.

[0041] Working principle: Splice the plate body 100 according to the distance between two butted cable trays 10. Snap the first sliders 611 and the second sliders 612 on the connecting plate 510 into the corresponding first sliding grooves 103 and the second sliding grooves 114 respectively, and pass the second bolts 500 through the first fixing holes 102 and the corresponding first through holes 601 as well as the second fixing holes 113 and the corresponding second through holes 602 to splice the sheet metal connectors; after completion of the splicing, insert both sides of the spliced sheet metal connector into the inner sides of the two cable trays 10 to be butted, so that the buckling end 120 is buckled into the corresponding buckling groove 301, and pass the first bolts 210 through the corresponding first mounting holes 111 and the second mounting holes 123 as well as the through holes 302 to realize the fixation of the buckling end 120 on the cable tray 10, and further complete the butt joint connection between the cable trays 10.
