[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figure 1 and Figure 2 , the present invention provides a connection structure 100, including a base member 10, an adjusting member 20, a limiting member 40 and a connecting member 30. The base member 10 can be connected to a first structural member, and the connecting member 30 can be connected to a second structural member. The first structural member and the second structural member are connected through the present connection structure 100.

[0033] Please refer to Figure 2 and Figure 3 , the present base member 10 has a mounting surface 11, and a bar-shaped extending abutting groove 12 is formed on its mounting surface 11. The radial cross-section of the bottom of the abutting groove 12 is circular arc-shaped, that is, the abutting groove 12 is formed by the extension of an arc axis. Among them, the base member 10 can be slidably connected to the first structural member, and the sliding direction of the base member 10 is the same as the extending direction of the abutting groove 12. The mounting surface 11 is arranged on the side of the base member 10 facing away from the first structural member. In this embodiment, the mounting surface 11 faces upward, and the base member 10 is located above the first structural member.

[0034] Please refer to Figure 2 and Figure 3, the adjusting member 20 is columnar and has a contact surface 21. The adjusting member 20 is inserted into the abutting groove 12 and protrudes from the mounting surface 11. The contact surface 21 abuts against and fits with the bottom of the abutting groove 12. The adjusting member 20 can rotate within the abutting groove 12 about the axis in its extending direction. The adjusting member 20 can be a cylinder. In this embodiment, the adjusting member 20 is semi-cylindrical, and its flat side can be used to mount the connecting member 30. Preferably, the central axis corresponding to the bottom of the abutting groove 12 coincides with the central axis corresponding to the contact surface 21, that is, the contact surface fits perfectly with the bottom surface of the abutting groove 12. At this time, the abutting groove 12 plays a limiting role, so that the adjusting member 20 can only rotate about its own axis and prevent the adjusting member 20 from translating.

[0035] The limiting member 40 is used to limit the separation of the adjusting member 20 from the bottom of the abutting groove 12, so that the adjusting member 20 always abuts against the bottom of the abutting groove 12 and can rotate about the axis.

[0036] Please refer to Figure 1 and Figure 2 , the connecting member 30 is connected to the side of the adjusting member 20 facing away from the base member 10. The connecting member 30 is spaced from the base member 10 to prevent the connecting member 30 from hindering the rotation of the adjusting member 20. Among them, the limiting member 40 can limit the position of the adjusting member 20 by limiting the position of the connecting member 30.

[0037] In the present invention, by providing the limiting member 40, the contact surface of the adjusting member 20 always abuts against the bottom of the abutting groove 12. The cross-section of the adjusting member 20 is arc-shaped and fits with the bottom of the abutting groove 12, so that it can rotate about the axis by itself. When the connecting member 30 is subjected to eccentric load, the adjusting member 20 can rotate about its own axis to buffer the connecting member 30, absorb the rotational energy generated by the eccentric load of the connecting member 30, prevent the connecting member 30 from driving the base member 10 to deflect, and improve the service life of the base member 10.

[0038] Please refer to Figure 1 and Figure 2 , in this embodiment, the limiting member 40 includes four limiting columns. The four limiting columns are arranged in pairs on both sides in the radial direction of the adjusting member 20 and are both connected to the base member 10, that is, on both sides in the radial direction of the abutting groove 12, to uniformly limit the rotation of the adjusting member 20. The limiting member 40 is columnar and extends in a direction perpendicular to the mounting surface 11; the connecting member 30 is slidably connected to the limiting columns. The arrangement of the limiting columns is used to prevent hindering the rotation of the adjusting member 20. The two ends of the connecting member 30 in the radial direction of the adjusting member 20 are respectively slidably connected to the limiting columns to adapt to the rotation of the adjusting member 20 within a certain angle range. When the connecting member 30 is subjected to eccentric load, the two ends of the connecting member 30 in the radial direction of the adjusting member 20 slide up and down relative to the limiting columns. The adjusting member 20 rotates under the action of an external force and absorbs external energy to buffer the eccentric load of the connecting member 30.

[0039] Among them, please refer toFigure 2 , the limiting post includes a post body 401 connected to the mounting surface 11 and extending in a direction perpendicular to the mounting surface 11, and a limiting cap 402 connected to the post body 401 and protruding from the side wall of the post body 401. The limiting cap 402 is spaced from the mounting surface 11, and the connecting member 30 is slidably connected to the post body 401 and is located between the limiting cap 402 and the mounting surface 11. In this way, the limiting cap 402 can limit the rotation angle of the adjusting member 20 and prevent the sliding member from slipping off the limiting post. The outer wall surface of the post body 401 may be provided with an external thread screwed to the base member 10, and the portion of the post body 401 slidably connected to the connecting member 30 may be a smooth wall surface to facilitate the sliding of the adjusting member 20.

[0040] To achieve the sliding connection between the connecting member 30 and the limiting post, please refer to Figure 2 , the connecting member 30 is provided with a plurality of connecting holes 31, the post body 401 passes through the connecting holes 31, and the limiting cap 402 is located on the side of the connecting member 30 facing away from the mounting surface 11 and is used to limit the connecting member 30 from sliding out of the post body 401. The limiting cap 402 may be provided on the middle side wall of the post body 401 or on the end of the post body 401 facing away from the base member 10. In this embodiment, the limiting post may be a screw.

[0041] Please refer to Figure 2 , the limiting post further includes a gasket 41 sleeved on the post body 401, and the gasket 41 is located between the limiting cap 402 and the adjusting member 20 to prevent the limiting cap 402 from scratching the surface of the connecting member 30.

[0042] Please refer to Figure 2 and Figure 3 , the base member 10 includes a slider 14 and a support portion 15 protruding from the slider 14. The side of the support portion 15 facing away from the slider 14 has a mounting surface 11, and the limiting member 40 is screwed to the side of the slider 14 facing the support portion 15. The connection of the limiting member 40 to the slider 14 increases the distance between the connecting member 30 and the slider 14, further preventing the connecting member 30 from restricting the rotation of the adjusting member 20.

[0043] Please refer to Figure 2 and Figure 3, wherein, at the extending end of the abutting groove 12 of the supporting portion 15, there is a limiting protrusion 151 protruding from the bottom of the abutting groove 12 and used to limit the axial movement of the adjusting member 20. The limiting protrusion 151 and the limiting post jointly limit the displacement of the adjusting member 20 and keep it in abutment with the bottom of the abutting groove 12. There are two limiting protrusions 151, which are respectively located at the two extending ends of the abutting groove 12. The limiting protrusion 151 preferably extends circumferentially around the axis of the abutting groove 12. Preferably, a limiting groove 17 is respectively formed at the four corners of the supporting portion 15. A limiting groove 17 is adapted to a column main body 401 to limit and position the column main body 401, which not only facilitates standardizing the perpendicularity of the limiting member 40 during installation, but also can prevent the limiting member 40 from shaking or shifting.

[0044] Please refer to Figure 5 , the present invention further provides a sliding door 200, including the connection structure 100 provided in each of the above embodiments. This connection structure 100 has the same structural features as the connection structures 100 in the above embodiments and plays the same role, which will not be elaborated here. The sliding door 200 further includes a door frame 101 and a guide rail 102. The guide rail 102 is equivalent to the first structural member, and the base member 10 is slidably connected to the guide rail 102. The door frame 101 is equivalent to the second structural member, and the door frame 101 is connected to the connecting member 30. One door frame 101 can be connected to multiple connection structures 100. In this way, when there is an eccentric load at different parts of the door frame 101, each connection structure 100 can buffer the eccentric load corresponding to different parts.

[0045] Please refer to Figure 2 and Figure 3 , the base member 10 is provided with a sliding groove 16 extending in the same direction as the abutting groove 12 and penetrating through. The guide rail 102 extends along the extending direction of the sliding groove 16 and is inserted into the sliding groove 16. The groove wall of the sliding groove 16 is provided with an anti-slip structure to limit the separation of the base member 10 from the guide rail 102. In this way, when the base member 10 slides along the guide rail 102, if the door frame 101 has an eccentric load, the eccentric load energy can be absorbed by the adjusting member 20 to prevent the base member 10 or the guide rail 102 from being deformed and displaced.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
