[0040] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. 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 the implementation of the present invention based on its overall structure.

[0042] Reference Figure 1 As shown, the embodiment of the present application provides a connection structure, including:

[0043] A connecting portion 1 having a central axis, through which at least one plate 2 and a support frame 3 are sequentially passed, and the at least one plate 2 and the support frame 3 are fixedly connected;

[0044] The support frame 3 has a first cavity 31 and a second cavity 32 connected along the direction in which the connecting portion 1 is extended. The inner diameter of the first cavity 31 is smaller than that of the second cavity 32. A floating core 4 is installed in the second cavity 31. The second cavity 32 is fixedly connected to a cover 5 away from the opening of the first cavity 31. The cover 5 and the floating core 4 are both sleeved on the outer wall of the connecting portion 1.

[0045] The maximum outer diameter of the floating core 4 is larger than the inner diameter of the first cavity 31 , and the maximum outer diameter of the floating core 4 is smaller than the inner diameter of the second cavity.

[0046] according to Figure 1 Those skilled in the art can set a structure in which the connecting portion 1 is connected to the plate 2 and the support frame 3. The connecting portion 1 has a middle axis, and the number of plates connected between the connecting portion and the support frame 3 is set to at least one.

[0047] During specific installation, the connecting portion 1 passes through at least one plate 2 and a support frame 3 in sequence, so that all the plates 2 and the support frames 3 can be fixedly connected.

[0048] In the above structure, the support frame 3 has a first cavity 31 and a second cavity 32 that are connected to each other. Moreover, the first cavity 31 and the second cavity 32 are arranged in sequence according to the direction in which the connecting portion 1 is installed.

[0049] With the above structure, during the insertion process, the connecting portion 1 is inserted from one side of the plate 2 into the first cavity 31 of the support frame 3 , and then inserted from the first cavity 31 into the second cavity 32 .

[0050] A cover 5 is fixedly connected to the opening of the second cavity 32 away from the first cavity 31 . The cover 5 is fixedly connected to the support frame 3 , and the connecting portion 1 passes through the cover 5 .

[0051] In the above arrangement, those skilled in the art can install the floating core 4 in the second cavity 32 of the support frame 3. That is, when the connecting portion 1 is inserted into the second cavity 32, it can be inserted into the floating core 4. The connecting portion 1 then passes through the floating core 4 and the cover 5.

[0052] Furthermore, those skilled in the art may also set the inner diameter of the first cavity 31 to be smaller than the inner diameter of the second cavity 32 , the maximum outer diameter of the floating core 4 to be larger than the inner diameter of the first cavity 31 , and the maximum outer diameter of the floating core 4 to be smaller than the inner diameter of the second cavity.

[0053] In summary, structurally, the connecting portion 1 passes through at least one plate 2 , the support frame 3 , and the cover 5 in sequence, and passes through the inside of the floating core 4 in the support frame 3 .

[0054] The connection structure formed by the connecting portion 1 passing through the plate 2, the support frame 3, and the cover 5 can maintain the stability of the connection due to the action of the floating core 4. The provision of the floating core 4 offsets the installation tolerance of the connection structure of the connecting portion 1, thereby making the connection structure of the connecting portion 1 more stable.

[0055] In an optional embodiment, preferably, the connection portion 1 is configured as a bolt. The bolts may produce installation tolerances in the structure for connecting the plate 2 and the support frame 3, thereby causing significant shaking after the bolts are connected, leading to failure of the connection structure.

[0056] In the above embodiment, the bolt passes through the middle of the floating core 4, and the relative position of the floating core 4 remains fixed, thereby absorbing the installation tolerance generated during the installation of the bolt.

[0057] It will be appreciated that, preferably, the floating core 4 is provided with internal threads for connection with bolts, and the threads are provided with self-locking features. That is, in this embodiment, the floating core 4 is connected to the bolts via the internal threads. The bolt-to-internal thread connection further stabilizes the connection between the floating core 4 and the connecting portion 1, thereby further stabilizing the connection between the connecting portion 1, the plate 2, and the support frame 3.

[0058] In this embodiment, those skilled in the art may provide a self-locking portion in the internal thread of the floating core 4 , and the relative position of the bolts may be locked by the self-locking portion.

[0059] Specifically, when the bolt passes through the cover 5 to form a stable connection structure, the self-locking portion provided in the internal thread of the floating core 4 engages with the thread of the outer wall of the bolt, thereby forming a self-locking structure.

[0060] To sum up, in this embodiment, the plate 2 and the support frame 3 can be connected by bolts, and a self-locking portion is provided in the internal thread of the floating core 4, and the relative position of the bolt can be locked by the self-locking portion, so that the floating core 4 can stably absorb the installation tolerance of the bolt.

[0061] In a preferred embodiment of the floating core 4, the cross-sectional shape of the floating core 4 perpendicular to the central axis is set to a polygon or an arc. When a person skilled in the art sets the cross-sectional shape of the floating core 4 perpendicular to the central axis to a polygon, the cross-sectional shape can be a square, a hexagon, or the like. When a person skilled in the art sets the cross-sectional shape of the floating core 4 perpendicular to the central axis to an arc, the cross-sectional shape can be a special shape or an ellipse.

[0062] It can be understood that the above-described configuration of the cross-sectional shape of the floating core 4 perpendicular to the central axis allows the connection structure to be applied in a variety of scenarios. It is worth noting that in all of the above configurations, the two side walls of the floating core 4, which are spaced apart along the central axis, must be maintained in contact with the inner wall of the second cavity 32 and the cover 5, respectively. In other words, the maximum outer diameter of the floating core 4 is greater than the inner diameter of the first cavity 31, and the maximum outer diameter of the floating core 4 is smaller than the inner diameter of the second cavity.

[0063] Those skilled in the art can set the cross-sectional shape of the second cavity 32 inside the support frame 3. In an optional embodiment, the cross-sectional shape of the second cavity 32 can be set to be the same as the cross-sectional shape of the floating core.

[0064] With the above arrangement, when the floating core 4 is arranged in different shapes, the floating core 4 and the inner wall of the second cavity 32 can avoid violent collision, thereby avoiding failure caused by damage to the outer wall material of the floating core 4 and the inner wall material of the second cavity 32.

[0065] In the above embodiment, the maximum outer diameter of the floating core 4 is greater than the inner diameter of the first cavity 31 and smaller than the inner diameter of the second cavity. Preferably, the outer wall of the floating core 4 remains separated from the inner wall of the second cavity 32. This prevents collision and compression between the outer wall of the floating core 4 and the inner wall of the second cavity 32, prevents relative movement of the floating core 4, and maintains the stability of the floating core 4 connection structure.

[0066] In the above embodiment, the connection portion 1 is provided with a cover portion 5, and the cover portion 5 is fixedly connected to the support frame 3. Preferably, the cover portion 5 is connected to the support frame 3 by flanging, bending or welding.

[0067] The cover 5 and the support frame 3 are connected by flanging, bending or welding, so that the cover 5 and the support frame 3 can be stably fixedly connected.

[0068] according to Figure 1 When arranging the panels 2, those skilled in the art may arrange multiple panels 2. In one embodiment, the multiple panels 2 may be arranged to be closely attached to each other. Preferably, the floating core 4 protrudes toward one side of the panel to form a step 33, which is fixedly connected to the adjacent panel 2.

[0069] With the above structure, the step portion 33 provided on the floating core 4 can be fixedly connected to the plate 2. In a structure in which multiple plates 2 are provided, the step portion 33 provided on the floating core 4 can be fixedly connected to adjacent plates 2, and the multiple plates 2 can abut against each other, thereby ensuring a stable connection of the multiple plates 2.

[0070] In an optional embodiment, preferably, the step portion 33 is connected to the adjacent plate 2 by riveting. In another embodiment, preferably, a riveting portion is provided on one side of the step portion 33 facing the plate, and the riveting portion is press-riveted into the adjacent plate.

[0071] Specifically, in the above two embodiments, those skilled in the art can set the step portion 33 to be riveted or press-riveted to the adjacent plate 2, thereby completing the fixed connection between the support frame and the plate 2.

[0072] In the above embodiment, the connection portion 1 can be configured as a bolt, and the connection can be achieved by the bolt. In this embodiment, preferably, the side of the bolt facing the plate 2 has a pressing portion 11, and the pressing portion 11 contacts the plate 2. In other words, the pressing portion 11 can be provided on the head of the bolt, and the pressing portion 11 is configured as a plate and contacts the plate 2, thereby fixing the relative position of the plate 2.

[0073] To sum up, through the above-mentioned settings, the clamping portion 11 can be set to be plate-shaped and in contact with the plate 2, and the step portion 33 can be riveted or press-riveted with the adjacent plate 2, thereby completing the clamping of multiple plates 2 from two distant sides, which is used to fix the relative positions of multiple plates.

[0074] according to Figure 2 , those skilled in the art can arrange for the outer wall of the connecting portion 1 to contact the inner wall of the first cavity 31. That is, in this embodiment, the installation position of the connecting portion 1 is at the extreme position of the support frame 3. In this installation situation, the floating core 4 can move within the second cavity 32, thereby maintaining the ability to absorb installation tolerances of the connecting portion 1.

[0075] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0076] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
