[0039] For the convenience of understanding, the accompanying drawings are used in the present application Figure 1 The direction shown by arrow A in the middle indicates the through direction of the accommodating groove 111.

[0040] Please refer to Figures 1 to 5 Now the character connection spare 1, pipe plate connecting structure and pipe group connecting structure provided by the utility model will be described.

[0041] The several-character connecting piece 1 comprises a bending part 11 and two connecting parts 12; the bending part 11 is provided with a containing groove 111 penetrating through two ends, and the containing groove 111 is open on one side and has a U-shaped structure with an opening; the containing groove 111 is used for mounting a to-be-connected piece extending along the penetrating direction of the containing groove 111; the two connecting parts 12 are respectively arranged at the two ends of the U-shaped structure of the bending part 11 and extend reversely away from the to-be-connected piece; wherein, along the penetrating direction of the containing groove 111, the two ends of the U-shaped structure of the bending part 11 are arranged in a staggered manner, and the two connecting parts 12 are also arranged in a staggered manner; on the projection plane perpendicular to the penetrating direction of the containing groove 111, the two connecting parts 12 and the bending part 11 form a several-character structure.

[0042] Specifically, the to-be-connected piece enters the containing groove 111 from the open side of the containing groove 111 and extends along the penetrating direction of the containing groove 111.

[0043] In order to realize the connection of the connecting part 12, a mounting hole needs to be arranged on the connecting part 12, which can be a threaded hole or a through hole, and the specific structure can be selected according to actual needs. Preferably, a set of mounting holes are arranged on each connecting part 12, so as to reduce the arrangement of connecting accessories, thereby further realizing the purpose of reducing material and reducing weight.

[0044] It needs to be understood that, since the two ends of the containing groove 111 are penetratingly arranged, the to-be-connected piece is conveniently arranged along the penetrating direction of the containing groove 111; and the containing groove 111 is open on one side, so that the remaining inner side wall surface of the containing groove 111 abuts against the to-be-connected piece.

[0045] Compared with the prior art, the several-character connecting piece 1 provided by the utility model can reduce the length size of the bending part 11 and reduce the number of threaded connecting pieces used when fixing the two connecting parts 12, thereby reducing the weight of the whole several-character connecting piece 1, effectively reducing the installation quality of the whole device when the several-character connecting piece 1 is used in large quantities, reducing the weight of the device, and effectively reducing the material cost by means of reducing material and reducing weight.

[0046] Please refer to Figure 2 In some possible embodiments, the U-shaped groove wall of the containing groove 111 has a shape matched with the outer peripheral surface of the to-be-connected piece.

[0047] Specifically, when the to-be-connected piece is a tubular structure with a circular cross section, the U-shaped groove wall of the accommodating groove 111 is in an arc structure that is adapted to the outer peripheral surface of the circular pipe; when the to-be-connected piece is a tubular structure with a rectangular cross section, the U-shaped groove wall of the accommodating groove 111 is in a planar structure that is adapted to the outer peripheral surface of the rectangular pipe; that is, the U-shaped groove wall of the accommodating groove 111 can be set according to actual needs.

[0048] Please refer to Figure 1 In some embodiments, the bending part 11 and the two connecting parts 12 are integrally bent and formed from a flat steel.

[0049] By integrally bending and forming the bending part 11 and the connecting part 12, the connection strength between the parts of the U-shaped connecting piece 1 can be ensured; at the same time, processing and manufacturing are facilitated.

[0050] Specifically, when designing a conventional U-shaped structure piece, a rectangular flat steel is often used for bending and forming; the raw material used in the U-shaped connecting piece 1 in the present application is half of the material of a conventional rectangular flat steel, and is in a parallelogram flat steel structure. Specifically, the length of the bottom side of the parallelogram flat steel is half of the width of the rectangular flat steel, and the height of the parallelogram flat steel is equal to the length of the rectangular flat steel. When processing the U-shaped connecting piece 1, a parallelogram flat steel with the required size is first cut, and then the accommodating groove 111 and the connecting part 12 are bent on the parallelogram flat steel to form the U-shaped connecting piece 1 in the present application.

[0051] Please refer to Figure 3 The present application also provides a pipe plate connecting structure, which comprises a plurality of the above U-shaped connecting pieces 1, a first mounting pipe 2 and a mounting plate 3. The plurality of the above U-shaped connecting pieces 1 are arranged at intervals along the through direction of the accommodating groove 111. The first mounting pipe 2 is arranged in the accommodating groove 111 of each U-shaped connecting piece 1. The mounting plate 3 is arranged at the bottom of the first mounting pipe 2 and abuts and fixes the bottom of the connecting part 12 of each U-shaped connecting piece 1, respectively.

[0052] By fixing the first mounting pipe 2 on the mounting plate 3 through the plurality of U-shaped connecting pieces 1, since the material used for each U-shaped connecting piece 1 is half of the material used in the conventional way, the material usage can be greatly reduced when the U-shaped connecting pieces 1 are used in large quantities for fixing.

[0053] Therefore, the pipe plate connecting structure provided in the present application has all the beneficial effects of the above U-shaped connecting piece 1 due to the use of a plurality of the above U-shaped connecting pieces 1, and can effectively reduce the installation quality of the overall device, reduce the weight of the device, and effectively reduce the material cost.

[0054] Please refer to Figure 4 and Figure 5The application also provides a pipe group connecting structure, which comprises a first connecting pipe 43, a second connecting pipe 5 and two above-mentioned L-shaped connecting pieces 1; the second connecting pipe 5 is arranged below the first connecting pipe 43 and is obliquely intersected with the first connecting pipe 43; the openings of the accommodating grooves 111 of the two L-shaped connecting pieces 1 are oppositely arranged; the L-shaped connecting piece 1 with the opening downward is defined as a first L-shaped connecting piece 6, and the L-shaped connecting piece 1 with the opening upward is defined as a second L-shaped connecting piece 7; the first L-shaped connecting piece 6 has a first bending part 61, two first connecting parts 62 and a first accommodating groove 611; the second L-shaped connecting piece 7 has a second bending part 71, two second connecting parts 72 and a second accommodating groove 711; wherein the first connecting pipe 43 is arranged in the first accommodating groove 611; the second connecting pipe 5 is arranged in the second accommodating groove 711, and the two first connecting parts 62 and the two second connecting parts 72 are correspondingly connected in up and down directions.

[0055] Specifically, since the first connecting pipe 43 and the second connecting pipe 5 are obliquely intersected, the first region, the second region, the third region and the fourth region are sequentially formed at the included angle of the first connecting pipe 43 and the second connecting pipe 5; and the two first connecting parts 62 of the first L-shaped connecting piece 6 are arranged in front and back directions in the through direction of the accommodating groove 111, so that the two first connecting parts 62 are correspondingly distributed in the opposite first region and the third region, or the two first connecting parts 62 are correspondingly distributed in the opposite second region and the fourth region; similarly, the two second connecting parts 72 are also correspondingly distributed in two opposite regions.

[0056] When the two first connecting parts 62 are correspondingly distributed in the opposite first region and the third region, the second L-shaped connecting piece 7 is adjusted so that the two second connecting parts 72 are also correspondingly distributed in the two opposite first region and the third region, so as to correspondingly connect the two first connecting parts 62 and the two second connecting parts 72 in up and down directions; similarly, when the two first connecting parts 62 are correspondingly distributed in the opposite second region and the fourth region, the second L-shaped connecting piece 7 is adjusted so that the two second connecting parts 72 are also correspondingly distributed in the two opposite second region and the fourth region, so as to correspondingly connect the two first connecting parts 62 and the two second connecting parts 72 in up and down directions.

[0057] Optionally, the connecting part 12 and the mounting plate 3 are fixed by connecting screws.

[0059] By making the first connecting part 62 and the second connecting part 72 correspondingly extend through the second connecting pipe 5 and the second connecting pipe 5, the first connecting part 62 and the second connecting part 72 are extended into the corresponding areas, thereby achieving the up-down butt joint fixing of the first connecting part 62 and the second connecting part 72.

[0060] Please refer to Figure 4 In some embodiments, the width of the first connecting part 62 abutting on the top of the second connecting pipe 5 is not greater than the width of the second connecting pipe 5; the width of the second connecting part 72 abutting on the bottom of the first connecting pipe 43 is not greater than the width of the first connecting pipe 43.

[0061] By limiting the abutment of the first connecting part 62 and the second connecting part 72, the material loss can be reduced as much as possible while ensuring the connection strength of the zigzag connecting piece 1, and the overall quality is reduced.

[0062] Please refer to Figure 4 For example, the extension end of the first connecting part 62 and the extension end of the second connecting part 72 are provided with connecting bolts, and one end of the connecting bolts sequentially passes through the first connecting part 62 and the second connecting part 72 and is fixed with a nut.

[0063] By setting the connecting bolts and the nuts, the first connecting part 62 and the second connecting part 72 are fixed; preferably, the first connecting part 62 and the second connecting part 72 are selected from high-strength bolts.
