Detailed Embodiment

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 2 , a high-strength steel connecting piece in this embodiment includes a connecting piece body 1. Connecting grooves 2 for connecting it with external components are provided at the upper and lower ends and the right side of the connecting piece body 1. Three limiting holes 3 are provided at the front end of the connecting piece body 1. A fastening bolt 4 is threadedly connected inside the limiting hole 3. A first stress relief groove 5 is provided at the front end of the connecting piece body 1. A second stress relief groove 6 is provided at the lower end of the right side wall of the connecting piece body 1. Strengthening components for enhancing its strength are provided at the front and rear ends of the connecting piece body 1.

[0030] Moreover, the limiting hole 3 communicates with the connecting groove 2, enabling the fastening bolt 4 to move into the interior of the connecting groove 2 through the limiting hole 3, so that it can cooperate with the mounting holes of external components and be fixed in the connecting groove 2 of the connecting piece main body 1, capable of applying a certain pre-tightening force to the connecting components, enabling it to better adapt to load changes during use and improving the reliability and stability of the connection.

[0031] Also, the connecting piece main body 1 is made of high-strength alloy steel material, and the hardness and toughness of the connecting piece main body 1 are improved through a heat treatment process, which can further enhance the strength of the connecting piece main body 1. And through the first stress relief groove 5 and the second stress relief groove 6, the phenomenon of stress concentration can be reduced, thereby reducing the probability of the connecting piece main body 1 breaking or deforming during use.

[0032] Please refer to Figures 1 to 3 , in this embodiment, the reinforcement assembly includes two groups of first reinforcing ribs 71, two groups of positioning bolts 73, two groups of gaskets 74, two groups of through holes 75, and two clamping blocks 72 fixedly installed on the opposite sides of the front and rear two groups of first reinforcing ribs 71. The gasket 74 is sleeved on the outside of the positioning bolt 73. The reinforcement assembly further includes a strengthening structure arranged in the first stress relief groove 5.

[0033] Among them, the front and rear two groups of through holes 75 are respectively opened on the opposite walls of the front and rear two groups of first reinforcing ribs 71. The positioning bolt 73 is threadedly connected to the interior of the through hole 75, enabling the positioning bolt 73 to penetrate out of the interior of the first reinforcing rib 71 through the through hole 75.

[0034] Meanwhile, eight connecting holes 76 are opened on both the front and rear walls of the connecting piece main body 1. The positioning bolt 73 is threadedly connected to the interior of the connecting hole 76, enabling the positioning bolt 73 penetrating the first reinforcing rib 71 to move into the connecting hole 76 of the connecting piece main body 1, thereby being able to fixedly install the first reinforcing rib 71 on the connecting piece main body 1.

[0035] In addition, eight insertion slots 77 are opened at both the front and rear ends of the connecting piece main body 1. The clamping block 72 is inserted into the interior of the insertion slot 77, enabling the first reinforcing rib 71 to be hung on the connecting piece main body 1 through the two clamping blocks 72, so as to prevent it from shaking when the positioning bolt 73 fixes and limits it.

[0036] Please refer to Figures 1 to 2 , in this embodiment, the strengthening structure includes two second reinforcing ribs 79, two clamping grooves 78, and two limiting bolts 710.

[0037] Secondly, both of the two card slots 78 are opened at the bottom of the inner cavity of the first stress relief groove 5, and the second reinforcing rib 79 is clamped inside the card slot 78, so that the second reinforcing rib 79 can be inserted into the first stress relief groove 5. In this way, while the first stress relief groove 5 releases pressure, its support strength can also be ensured. Moreover, both the first reinforcing rib 71 and the second reinforcing rib 79 are made of carbon fiber composite materials, which can replace those made of traditional steel. This can reduce the overall weight of the connector body 1 while also improving its strength.

[0038] In addition, through holes for the limit bolts 710 to penetrate through their interiors are opened on the left sides of both of the two second reinforcing ribs 79, so that the limit bolts 710 can play a role in limiting the second reinforcing ribs 79, enabling the two second reinforcing ribs 79 to be stably located inside the first stress relief groove 5.

[0039] Furthermore, two threaded holes 711 are opened on the left side of the connector body 1, and two screw holes 712 are opened on the right wall of the inner cavity of the first stress relief groove 5. The limit bolts 710 are all threadedly connected to the interiors of the threaded holes 711 and the screw holes 712. In this way, the limit bolts 710 can penetrate into the first stress relief groove 5 through the threaded holes 711 and move into the screw holes 712, so that they can be fixed inside the first stress relief groove 5.

[0040] The working principle of the above embodiment is as follows:

[0041] During use, through the first stress relief groove 5 and the second stress relief groove 6, stress concentration at the right end and the middle of the connector body 1 can be reduced, thereby reducing the probability of the connector body 1 breaking or deforming during use. The first reinforcing rib 71 can be inserted into the two corresponding insertion slots 77 of the connector body 1 through the two corresponding clamping blocks 72. That is, it is possible to move the positioning bolt 73 into the through hole 75 of the first reinforcing rib 71 and penetrate out of its interior, so that the positioning bolt 73 can move to the connecting hole 76 of the connector body 1. Repeat the above steps to fixedly install the other three first reinforcing ribs 71 on the connector body 1, so as to improve the strength of the right end of the connector body 1, thereby enhancing the bearing capacity of this area of the connector body 1, and improving the connection stability between the connector body 1 and the external connecting components.

[0042] And by inserting the second reinforcing rib 79 into the card slot 78 of the first stress relief groove 5, the limit bolt 710 penetrates into the first stress relief groove 5 through the threaded hole 711. At the same time, the limit bolt 710 can penetrate into the through holes of the two second reinforcing ribs 79 and move into the screw hole 712, so as to fix the two second reinforcing ribs 79 inside the first stress relief groove 5. Thus, when the first stress relief groove 5 disperses the stress concentrated in the middle of the connector body 1, the support strength of the connector body 1 can also be ensured.
