For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0030] Reference Figure 1 As shown, the embodiment of the present application provides a direct pressure bolt, comprising:

[0031] Main body 1;

[0032] A connecting portion 2 installed on one side of the main body 1;

[0033] A riveting portion 3 is installed on one side of the main body 1 facing the connecting portion 2. The riveting portion 3 is sleeved on the outer wall of the connecting portion 2, and the maximum distance between the riveting portion 3 and the main body 1 is smaller than the maximum distance between the connecting portion 2 and the main body 1.

[0034] A preset gap is provided between the inner wall of the riveted portion 3 and the outer wall of the connecting portion 2, and the outer wall of the riveted portion 3 contacts the inner wall of the plate 4. The end side of the riveted portion 3 away from the main body 1 is deformed toward the position of the plate 4 to form a deformation portion 31, and the deformation portion 31 contacts the side wall of the plate 4.

[0035] A plurality of reinforcing ribs 11 are disposed on the side wall of the main body 1 facing the plate 4 , and the plurality of reinforcing ribs 11 are all embedded in the side wall of the plate 4 facing the main body 1 .

[0036] Those skilled in the art will Figure 1 The main body 1 may be provided, and the connecting part 2 may be installed on one side of the main body 1. The rivet part 3 may be installed on one side of the main body 1 facing the connecting part 2.

[0037] Specifically, the riveted portion 3 is fixedly connected to the main body 1 on one side thereof. Furthermore, the riveted portion 3 extends in the direction where the connecting portion 2 is located. Figure 2 The riveted portion 3 is arranged in a ring shape. Those skilled in the art may arrange the riveted portion 3 to be sleeved on the outer wall of the connecting portion 2. Moreover, a preset gap is arranged between the inner wall of the riveted portion 3 and the outer wall of the connecting portion 2.

[0038] Those skilled in the art may set the outer wall of the riveted portion 3 to collide with the inner wall of the plate 4. In one embodiment, the plate 4 may be provided with a pre-opened mounting hole. The outer wall of the riveted portion 3 collide with the inner wall of the mounting hole.

[0039] During the riveting process, the end of the riveting portion 3 away from the main body 1 is deformed by pressure riveting toward the position of the plate, thereby forming a deformation portion 31. The deformation portion 31 faces the side wall of the plate 4 and contacts and presses the plate 4.

[0040] It is understandable that according to Figure 2 The deformation part 31 is deformed in the direction opposite to the position of the connection part 2. Then, a structure in which the deformation part 31 and the plate 4 are pressed tightly can be formed.

[0041] In summary, the end side of the riveting portion 3 away from the main body 1 is subjected to pressure riveting deformation to form the deformation portion 31. The deformation portion 31 is pressed against the plate 4. Thus, the plate 4 can be stably riveted.

[0042] Furthermore, a plurality of reinforcing ribs 11 are provided on the side wall of the main body 1 facing the plate 4. During the process of riveting the deformed portion 31 on the riveting portion 3, the plurality of reinforcing ribs 11 are all embedded in the side wall of the plate 4 facing the main body 1.

[0043] Specifically, during the riveting process, an external force is applied from the location of the connection portion 2 toward the location of the main body 1. Thus, the reinforcing rib 11 can be pressed into the side wall of the plate 4 facing the main body 1 while the riveting is completed.

[0044] It is understandable that in the structure where the plate 4 is riveted, the plate 4 may rotate when subjected to other external forces, thereby rendering the riveting ineffective. In the structure where the reinforcing rib 11 is embedded in the plate 4, the plate 4 may be prevented from rotating relative to each other.

[0045] In summary, providing the reinforcing ribs 11 in the riveted structure can make the riveted structure more stable and also make the riveting of the plate 4 more reliable during operation.

[0046] In the arrangement of the reinforcing ribs 11, preferably, the end sides of the plurality of reinforcing ribs 11 close to the riveted portion 3 are connected to the riveted portion 3. The aforementioned arrangement can allow the portion where the reinforcing ribs 11 are connected to the riveted portion 3 to withstand greater stress.

[0047] It is understandable that during the operation of the riveted structure, stress concentration may occur on the reinforcing rib 11. In this embodiment, the end side of the reinforcing rib 11 close to the riveted portion 3 is connected to the riveted portion 3, thereby preventing the reinforcing rib 11 from breaking when stress is concentrated.

[0048] Furthermore, in order to improve the service life of the riveted structure, preferably, the plurality of reinforcing ribs 11 are evenly arranged, so that when the reinforcing ribs 11 are subjected to an external force causing the plate 4 to rotate, the force on each reinforcing rib 11 can be evenly distributed.

[0049] According to the above structure, it is possible to avoid excessive force on a single reinforcing rib 11, which may cause the single reinforcing rib 11 to break, that is, the reliability of the reinforcing rib 11 in the riveted structure is improved.

[0050] Preferably, the maximum distance between the reinforcing rib 11 and the main body 1 is less than the maximum distance between the riveted part 3 and the main body 1. That is, the maximum distance between the reinforcing rib 11 and the main body 1 is set to the maximum height of the reinforcing rib 11. The maximum distance between the riveted part 3 and the main body 1 is set to the setting width of the riveted part 3.

[0051] Specifically, the maximum height of the reinforcing rib 11 is smaller than the width of the riveted portion 3 , so that the plate 4 can be stably sleeved on the outer wall of the riveted portion 3 during installation.

[0052] More preferably, the cross section of the reinforcing rib 11 is set to be triangular, and the distance from the end side of the reinforcing rib 11 close to the riveted portion 3 to the main body 1 is greater than the distance from the end side of the reinforcing rib 11 away from the riveted portion 3 to the main body 1. Figure 3The cross section of the reinforcing rib 11 is set to be triangular, which can make it easier to press the reinforcing rib 11 into the plate 4. Specifically, the end side of the reinforcing rib 11 facing the plate 4 has a smaller contact surface with the plate 4, thereby applying a greater pressure to the plate 4.

[0053] The distance between the end of the reinforcing rib 11 close to the riveted portion 3 and the main body 1 is set to be greater than the distance between the end of the reinforcing rib 11 far from the riveted portion 3 and the main body 1, so that the structural setting of the reinforcing rib 11 can be more reasonable. In addition, during the process of fitting the plate 4, the plate 4 can be prevented from being crushed.

[0054] For the riveted structure, after the deformation part 31 is riveted, preferably, the diameter of the deformation part 31 is smaller than the diameter of the main body 1. That is, in this embodiment, the deformation part 31 stably presses the plate 4. At the same time, it is also convenient for the connection part 2 to connect other parts.

[0055] In this embodiment, the connecting portion 2 can be configured as a threaded column. Preferably, the plane where the deformation portion 31 is located is parallel to the plane where the main body 1 is located. The aforementioned structure makes the deformation portion 31 and the main body 1 more stable when they are matched with the plate 4.

The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.

[0057] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
