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

[0045] Reference Figure 1As shown, the embodiment of the present application provides an elastic variable I-shaped nail, comprising:

[0046] The main body 1 includes a first end 11 and a second end 12;

[0047] A support frame 2 is sleeved on the middle position of the main body 1, the support frame 2 has a first side 21 and a second side 22, and the first end portion 11 is inserted into the support frame;

[0048] A connecting portion 3 fixedly connected to the second end portion 12, the connecting portion 3 is inserted into the support frame 2, and a riveted portion 4 is fixedly connected to a side of the connecting portion 3 away from the main body 1;

[0049] An elastic member 5 is sleeved on the outer wall of the main body 1, and two ends of the elastic member 5 are respectively in contact with the inner wall of the support frame 2 and the outer wall of the connecting portion 3;

[0050] The head portion 6 is fixedly mounted on the second end portion 12 , and the maximum outer diameter of the head portion 6 is greater than the maximum outer diameter of the main body portion 1 .

[0051] according to Figure 1 , those skilled in the art can set the elastic variable I-shaped nail to include a main body 1, a support frame 2 and a connecting part 3. Among them, the main body 1 is connected to the connecting part 3.

[0052] With the above structure, those skilled in the art can arrange that both ends of the main body 1 pass through both sides of the support frame 2, and one end of the main body 1 is fixedly connected to the connecting part 3, thereby forming a structure connected by an I-shaped nail.

[0053] Specifically, those skilled in the art may set the two ends of the main body 1 to be the first end 11 and the second end 12. The support frame 2 has a first side 21 and a second side 22. In the above embodiment, the first end 11 of the main body 1 is inserted into the support frame 2 from the first side 21 of the support frame 2.

[0054] Furthermore, those skilled in the art arrange that the first end 11 of the main body 1 is fixedly connected to the connecting portion 3. It is understandable that the first end 11 is connected to the connecting portion 3, and the connecting portion 3 has two states: being placed in the support frame 2 and being passed through the support frame 2.

[0055] according to Figure 1 The main body 1 and the connecting portion 3 connected to the first end portion 11 are an integrated structure. Those skilled in the art can move the aforementioned integrated structure, thereby realizing the transition between the connecting portion 3 being placed in the support frame 2 and being passed through the support frame 2.

[0056] A rivet portion 4 is fixedly connected to the side wall of the connecting portion 3 away from the main body portion 1 , so that the connecting portion 3 can be connected to an external part through the rivet portion 4 .

[0057] The connecting portion 3 is fixedly connected to the riveting portion 4, and at the same time, the connecting portion 3 is fixedly connected to the main body 1. Furthermore, a head 6 is fixedly mounted on the first end portion 11 of the main body 1.

[0058] With the above structure, those skilled in the art connect the head 6, the main body 1, the connecting part 3 and the riveting part 4 to form an I-shaped nail structure.

[0059] In the above-mentioned I-shaped nail structure, the support frame 2 is sleeved in the middle position of the main body 1. Further, those skilled in the art can arrange that an elastic member 5 is sleeved on the outer wall of the main body 1. The elastic member 5 is placed inside the support frame 2, and the two ends of the elastic member 5 are fixedly connected to the inner wall of the support frame 2 and the outer wall of the connecting portion 3 respectively.

[0060] By means of the above structure, the elastic member 5 is arranged in the middle position of the main body 1, and the relative position of the main body 1 can be limited by the elastic member 5. That is, when the main body 1 is in the initial state, the elastic member 5 is in the initial state; when the main body 1 moves along the direction of the first end 11 toward the second end 12, the elastic member 5 can be stretched, and the position of the main body 1 can be kept stable under the action of the elastic member 5, thereby avoiding the shaking of the main body 1 during the movement.

[0061] In one embodiment, preferably, a first inner cavity 23 and a second inner cavity 24 are connected to each other in the support frame 2, wherein the inner diameter of the first inner cavity 23 is smaller than the outer diameter of the connecting portion 3, and the inner diameter of the second inner cavity 24 is larger than the outer diameter of the connecting portion 3.

[0062] With the above structure, the connecting portion 3 can be accommodated in the second inner cavity 24 , and the connecting portion 3 can contact with the outer wall of the first inner cavity 23 .

[0063] It can be understood that the structure of the connecting portion 3 accommodating the second inner cavity 24 can make the structure of the I-shaped nail more reasonable, making the I-shaped nail more convenient during installation.

[0064] In an optional embodiment, preferably, the side wall of the head 6 facing the main body 1 is set to be an inverted cone. In another optional embodiment, preferably, the side wall of the head 6 facing the main body 1 is set to be spherical.

[0065] With the above structure, the head 6 of the I-nail can stably contact the outer wall of the external part during the process of connecting different external parts, avoiding the situation where the head 6 is squeezed against the wall of the main body 1 and crushed by the outer wall of the external part.

[0066] Preferably, the distance between the first side 21 and the second side 22 of the support frame 2 is greater than the length of the main body 1. That is, the main body 1 can be completely accommodated in the support frame 2, so that the structure connected by the I-shaped nails does not produce an additional protruding structure.

[0067] By means of the above structure, the I-shaped nail structure can avoid interference with other parts during installation, and at the same time, the space utilization of the structure after installation is more reasonable.

[0068] In an optional embodiment, a receiving groove is formed on a side of the head 6 facing the main body 1 , and the inner diameter of the receiving groove is greater than the maximum outer diameter of the support frame 2 .

[0069] By means of the above structure, the structure of the support frame 2 can be accommodated in the head 6, so that the I-nail connection structure can be protected by the receiving groove of the head 6 after the connection is completed.

[0070] Preferably, those skilled in the art may configure a countersunk hole on one side of the support frame 2 facing the head 2 , the countersunk hole being connected to the first inner cavity 23 , and the aperture of the countersunk hole being larger than the inner diameter of the first inner cavity 23 .

[0071] By means of the above structure, the head 6 can be accommodated by the countersunk hole, thereby making the structural setting of the I-shaped nail more reasonable, that is, the head 6 will not form a large protrusion on one side of the support frame 2. The above setting can make the installation process of the I-shaped nail more stable and improve the reliability of the use of the I-shaped nail structure.

[0072] The present specification also provides an elastic variable I-shaped nail connection structure, including the elastic variable I-shaped nail in the above embodiment, a first plate 7 is sleeved on the outer wall of the main body 1 close to the first end 11, the first plate 7 is in contact with the support frame 2, and the first plate 7 is in contact with the head 6; the riveting part 4 is fixedly connected with the second plate 8;

[0073] Among them, the first plate 7 has a first connecting hole 71 and a second connecting hole 72, the aperture of the first connecting hole 71 is smaller than the aperture of the second connecting hole 72, when the main body 1 is inserted into the first connecting hole 71, the first plate 7 is locked, and when the main body 1 is inserted into the second connecting hole 72, the first plate 7 is unlocked.

[0074] By means of the above structure, the first plate 7 and the second plate 8 can be connected, thereby realizing a structure in which the two plates are connected simultaneously.

[0075] It is understandable that those skilled in the art can insert the main body 1 into the first connection hole 71 , and the hole diameter of the first connection hole 71 is small, so that the first plate can be locked.

[0076] A person skilled in the art moves the main body 1 from the first connection hole 71 to the second connection hole 72. The second connection hole 72 has a larger hole diameter, so that the first plate can be unlocked.

[0077] In the above-mentioned embodiment, the diameter of the first connection hole 71 is smaller than the outer diameter of the head, and the diameter of the second connection hole 72 is larger than the outer diameter of the head.

[0078] In an optional implementation of this embodiment, preferably, the first plate 7 is parallel to the second plate 8. That is, the elastic variable I-shaped nail structure can connect the first plate 7 and the second plate 8 which are parallel to each other.

[0079] In another optional embodiment, preferably, the riveted portion 4 is connected to the second plate 8 by press riveting. Or, preferably, the riveted portion 4 is connected to the second plate 8 by flip riveting. That is, according to different connection requirements, those skilled in the art can connect the second plate 8 by press riveting or flip riveting.

[0080] More preferably, the press riveting connection includes forward press riveting and reverse press riveting. That is, in the process of press riveting connection, those skilled in the art use forward press riveting and reverse press riveting according to further installation requirements.

[0081] In summary, in the process of riveting the second plate 8, flip riveting connection or press riveting connection can be adopted, and the press riveting connection includes forward press riveting and reverse press riveting, thereby improving the convenience of connecting the second plate 8.

[0082] Although different specific embodiments are mentioned in the content of this application, this application is not limited to the situations described in the industry standards or embodiments, etc. Some industry standards or slightly modified implementation plans based on the implementation of the custom methods or embodiments can also achieve the same, equivalent or similar, or predictable implementation effects after deformation of the above embodiments.
