DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0038] The following is an explanation of the embodiments of the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0039] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0040] See also Figure 1 and Figure 8 , is a riveted tube joint of this embodiment, used to connect with the mounting hole 200 on the tooling 100, wherein the riveted tube joint includes:

[0041] A flange portion 1, wherein the flange portion 1 has a first surface and a second surface that are oppositely disposed, and an outer diameter of the flange portion 1 is larger than a hole diameter of the mounting hole 200;

[0042] The mounting portion 2 is connected to the first surface of the flange portion 1 , and is used to be passed through and riveted into the mounting hole 200 , so that the first surface of the flange portion 1 abuts against the tooling 100 .

[0043] For the above structure, during installation, the operator only needs to select the riveted tube joint of the flange part 1 and the mounting part 2 of the corresponding size, and then rivet one side of the mounting part 2 toward the mounting hole 200 until the mounting part 2 abuts against the outer wall surface of the tooling 100 at the mounting hole 200. At this time, the sealing operation of the mounting hole 200 is achieved. Finally, the riveted tube joint itself can be used to achieve complete sealing of the mounting hole 200, or connection with an external water pipe, or other functions.

[0044] Through the above structure, the flange part 1 fits tightly on the tooling 100. Compared with the existing method that requires fixing by welding, its installation is simpler, and the structure can be customized on both sides of the first and second surfaces of the flange part 1, which has higher flexibility and a wider range of applications.

[0045] Based on the above structure, starting from the riveting fixing method between the mounting portion 2 and the mounting hole 200, there are the following embodiments.

[0046] Example 1

[0047] See also Figure 2The mounting portion 2 in this embodiment includes an external thread 21, the maximum outer diameter of which is larger than the diameter of the mounting hole 200, and the external thread 21 is used to be screwed into the mounting hole 200, and the inner hole wall of the mounting hole 200 forms an internal thread that fits the external thread 21, so that the mounting portion 2 is fixed relative to the mounting hole 200. Specifically, the external thread 21 on one side of the mounting portion 2 can be rotated and tapped into the mounting hole 200, so that during the process of the external thread 21 rotating into the mounting hole, a corresponding matching internal thread is cut out on the inner wall of the mounting hole 200, so as to achieve mutual fixation.

[0048] Example 2

[0049] See also Figure 3 The mounting portion 2 in this embodiment includes a plurality of oblique teeth 22 that are axially inclined and coiled around the outer wall of the mounting portion 2. A tooth groove is provided between a pair of adjacent oblique teeth 22. The oblique teeth 22 are used to be pressed into the mounting hole 200. At least a portion of the inner hole wall of the mounting hole 200 is squeezed into the tooth grooves on both sides by the oblique teeth 22, so that the mounting portion 2 is fixed relative to the mounting hole 200. Specifically, a force can be applied from one side of the second surface of the flange portion 1 by a press so that the mounting portion 2 is squeezed into the mounting hole 200, so that the oblique teeth 22 are pressed into the depth of the mounting hole 200 from the end adjacent to the mounting hole 200 by high pressure with a triangular cross section. At the same time, the material in the mounting hole 200 is squeezed into the tooth groove gaps on both sides of the oblique teeth 22 by the oblique teeth 22 to achieve a sealing and fixing effect.

[0050] Based on the structural features of the helical teeth 22 of the above-mentioned embodiment 2, the present invention further provides the following embodiments in order to enhance the fixing and sealing effects or expand the functions.

[0051] Example 4

[0052] Please continue to refer to Figure 3 Each bevel tooth 22 has an end surface 221 at the end facing the depth of the mounting hole 200, and the end surface 221 is inclined toward the outside of the mounting hole 200. Specifically, compared with the horizontal end surface 221, the end surface 221 at the end of the bevel tooth 22 has a better pressing and guiding effect, which helps to improve the pressing speed and stability.

[0053] Example 5

[0054] See also Figure 5, there is a material receiving portion 23 which is concave in the axial direction between the helical teeth 22 and the first surface of the flange portion 1, and the material receiving portion 23 is used to accommodate the inner hole wall of the mounting hole 200 after being squeezed, and the minimum outer diameter of the material receiving portion 23 is smaller than the outer diameter of the tooth groove. Specifically, there is a material discharging portion 24 between the material receiving portion 22 and the first surface of the flange portion 1, and the outer diameter of the material discharging portion 24 is larger than the hole diameter of the mounting hole 200, and the material discharging portion 24 is used to squeeze at least part of the inner hole wall of the mounting hole 200 into the material receiving portion 22, or the outer edge of the material discharging portion 24 in the radial direction. Through the above structure, during the process of pressing the mounting portion 2, after the helical teeth 22 are partially pressed in the axial direction, the part of the material body squeezed at the mounting hole 200 of the tool 100 will touch the area of ​​the material discharging portion 24, so that the material discharging portion 24 forms a certain blocking effect on the material body in the axial direction, and squeezes into the material receiving portion 23 between the material discharging portion 24 and the helical teeth 22, so that the material receiving portion 23 is filled with the flowing material body. Therefore, after the final molding, the torsion resistance of the riveted tube joint is enhanced by means of the material body in the material receiving portion 23. It is worth noting that since the minimum outer diameter of the material receiving portion 23 is smaller than the outer diameter of the tooth groove, the material body can be squeezed into the material receiving portion 22 without hindrance. At the same time, the material receiving portion 22 can also have an axial concave along the direction of the discharge portion 24, and the material is filled in the concave, so that the radial force resistance effect in this embodiment is better.

[0055] Example 6

[0056] Based on Example 5, in this embodiment, the wall surface of the material receiving portion 23 is coated with sealant. Therefore, after the material body of the mounting hole 200 is squeezed into the material receiving portion 23, the presence of the sealant provides a better sealing effect at the material receiving portion 23, thereby preventing the fluid from penetrating from both sides.

[0057] The following embodiments are based on the original flange portion 1 and the mounting portion 2 in order to achieve a better sealing effect and avoid fluid leakage during the process of liquid cooling in the tooling 100 .

[0058] Example 7

[0059] See also Figure 5 In this embodiment, the mounting portion 2 has a radially concave groove, which is used to cover the first sealing ring 25. After installation, the first sealing ring 25 is in close contact with the mounting hole 200, so that the fluid before and after the first sealing ring 25 is blocked.

[0060] Example 8

[0061] See also Figure 4A second sealing ring 11 is provided between the first surface of the flange 1 and the tooling 100, and the second sealing ring 11 is used to abut against the tooling 100. Specifically, after installation, the second sealing ring 11 is tightly fitted on the outer wall of the tooling 100, so that the radial area of ​​the mounting hole 200 is annularly sealed, further limiting the leakage of the fluid from the flange 1. Of course, the flange 1 and the tooling 100 here can also be treated with a sealant to achieve a similar effect.

[0062] In some other embodiments, such as Figure 1 As shown, the riveted pipe joint has a through hole 3 extending axially therethrough, and the through hole 3 is used for the flow of fluid. Of course, in another embodiment, as Figure 7 As shown, the riveted tube joint does not have a through hole 3, which mainly serves a sealing function.

[0063] Based on the structure with the through hole 3, various connection modes as shown in the following embodiments can be realized, and a better sealing effect is achieved.

[0064] Example 9

[0065] like Figure 1 As shown, the through hole 3 has an internal thread at the position of the mounting portion, so that a structure with an external thread on the outside can be directly screwed into the through hole 3 to achieve connection.

[0066] Example 10

[0067] like Figure 4 As shown, in this embodiment, the riveted tube joint further includes a connection portion 4 for screwing into the external water pipe, the connection portion 4 is connected to the second surface of the flange portion 1, and the connection portion 4 has an external thread, or the through hole 3 has an internal thread at the position of the connection portion 4. Based on this structure, the external water pipe is directly screwed into the internal thread of the connection portion 4 to form a fixed fit, and the protruding connection portion 4 structure requires a smaller opening area of ​​the mounting hole 200.

[0068] Embodiment 11

[0069] like Figure 2 As shown in FIG. 5 , the riveted tube joint further includes a tube body 5 for embedding in the external hose, and the tube body 5 is connected to the second surface of the flange portion 1. Specifically, the tube body 5 includes at least one radially outwardly protruding inverted tooth 51, and the inverted tooth 51 is used to clamp the tube body 5 in the hose, or to guide the tube body 5 when inserting the hose. Based on this embodiment, the tube body 5 has a bamboo-like structure, which is easier to connect with the hose on the basis of the inverted tooth 51 guiding, and is not easy to detach from the hose on the basis of the inverted tooth 51 supporting and providing friction.
