[0002] A building connection structure is disclosed in the prior art, which involves filling the mounting holes of building structural members with material and then connecting them to the structural members via an interference fit. However, the installation of the existing connection structure is relatively difficult and the operation is relatively complex. Summary of the Invention

[0003] Therefore, it is necessary to provide a new connection structure to address the problems of difficult installation and complex operation of existing connection structures.

[0004] According to a first aspect of this application, a connection structure is provided for connecting a first structural member and a second structural member, the first structural member having a mounting hole. The connection structure includes:

[0005] A connecting rod, comprising a first segment and a second segment sequentially connected along the axial direction of the connecting rod, wherein the first segment is used to connect to the second structural member; and

[0006] An elastic component, arranged in a cylindrical shape, is sleeved on the second section and includes multiple crest segments and multiple trough segments. The crest segments and trough segments are alternately connected so that the elastic component can deform radially along the mounting hole and be squeezed into the mounting hole of the first structural member, and connected to the inner wall of the mounting hole.

[0007] In one embodiment, the crest segments and the trough segments are alternately connected in a ring structure along the circumference of the mounting hole.

[0008] In one embodiment, the crest segments and the trough segments are alternately connected in a ring structure along the axial direction of the mounting hole.

[0009] In one embodiment, each of the wave crests is provided with a connecting portion for connecting to the inner wall of the mounting hole.

[0010] In one embodiment, the sidewall of the mounting hole is provided with a first tooth;

[0011] The connection structure further includes a connection portion disposed on the outside of the elastic member, the connection portion including a second tooth corresponding to the first tooth, the elastic member being connected to the first structural member by means of the second tooth and the first tooth.

[0012] In one embodiment, the second teeth are continuously distributed on the outer periphery of the elastic member; or

[0013] The second tooth spacing is arranged on multiple wave crest segments of the elastic member.

[0014] In one embodiment, the radial dimension of the second segment gradually increases from the first segment to the second segment along the axial direction of the elastic member;

[0015] The elastic component has a sleeve hole that is adapted to the second segment.

[0016] In one embodiment, the outer diameter of the elastic member remains constant along the axial direction of the elastic member from the first segment to the second segment.

[0017] In one embodiment, the elastic member has a first end and a second end disposed opposite to each other along the axial direction of the elastic member; a first contraction opening is provided through the first end of the elastic member radially through the elastic member, and a second contraction opening is provided through the second end of the elastic member radially through the elastic member, and the sum of the length of the first contraction opening and the length of the second contraction opening is greater than or equal to the length of the elastic member along the axial direction of the elastic member.

[0018] In one embodiment, the width of the first contraction opening is greater than the width of the second contraction opening along the circumferential direction of the elastic member.

[0019] In one embodiment, the number of the first contraction openings is greater than the number of the second contraction openings.

[0020] In one embodiment, the elastic member has a first end and a second end disposed opposite to each other along the axial direction of the elastic member; a first contraction opening is provided through the first end of the elastic member in the radial direction of the elastic member, and the size of the first contraction opening gradually increases in the radial direction of the elastic member from the second end to the first end.

[0021] In one embodiment, each of the trough segments abuts against the connecting rod.

[0022] In one embodiment, the connecting rod has a flange at one end near the second segment, the radial dimension of the flange being larger than the inner diameter of the elastic member, to restrict the elastic member from detaching from the second segment.

[0023] In one embodiment, the flange has a limiting surface facing the elastic member on the side near the elastic member, and the elastic member has a mating surface corresponding to the limiting surface, the mating surface being located at one end near the flange;

[0024] The limiting surface extends obliquely inward toward the elastic member, and the contact surface extends obliquely outward toward the elastic member to contact the limiting surface.

[0025] In one embodiment, the number of wave crest segments of the elastic component is greater than or equal to 4 and less than or equal to 24.

[0026] In the technical solution of this application, the connecting structure is connected to the second structural member via a connecting rod and to the first structural member via an elastic component. The first segment of the connecting rod is used to connect to the second structural member, and the connection between the first segment and the second structural member can be a screw connection. Furthermore, the elastic component is sleeved on the second segment, and the crest and trough segments are alternately connected to form the elastic component. This creates a gap between the crest segment and the second segment, allowing the elastic component to deform radially along the mounting hole and be inserted into the mounting hole of the first structural member.

[0027] The first structural member is connected to the connecting rod, and the second structural member is connected to the elastic component. The elastic component is fitted onto the second section of the connecting rod, thereby connecting to the connecting rod. In other words, the first and second structural members can be connected to the elastic component via the connecting rod. The structural design of the connection structure proposed in this application is simpler and easier to install compared to existing technologies. Attached Figure Description

[0046] A building connection structure is disclosed in the prior art, which involves filling the mounting holes of building structural members with material and then connecting them to the structural members via an interference fit. However, the installation of the existing connection structure is relatively difficult and the operation is relatively complex.

[0047] Based on their research, the inventors of this application have discovered that existing building connection structures require filling the mounting holes facing the building structure with material, making installation difficult and operation complex. Therefore, the inventors of this application propose a connection structure that can directly connect the first structural member and the second structural member.

[0048] In view of this, this application proposes a connection structure that aims to solve the problems of difficult installation and complicated operation of existing connection structures. Figures 1 to 10 This is a schematic diagram of one embodiment of the connection structure proposed in this application.

[0049] Please see Figure 1 and Figure 2 The connection structure 100 proposed in this application is used to connect a first structural member 200 and a second structural member 300. The first structural member 200 has a mounting hole. The connection structure 100 includes a connecting rod 1 and an elastic member 2. The connecting rod 1 includes a first segment 11 and a second segment 12 connected sequentially along the axial direction of the connecting rod 1. The first segment 11 is used to connect with the second structural member 300.

[0050] The elastic component 2 is cylindrical and is sleeved on the second section 12. It includes multiple crest sections 23 and multiple trough sections 24. The crest sections 23 and trough sections 24 are alternately connected so that the elastic component 2 can deform radially along the mounting hole and squeeze into the mounting hole of the first structural member 200 and connect to the inner wall of the mounting hole.

[0051] In the technical solution of this application, the connecting structure 100 is connected to the second structural member 300 via a connecting rod 1, and to the first structural member 200 via an elastic member 2. The first segment 11 of the connecting rod 1 is used to connect with the second structural member 300, and the specific connection method between the first segment 11 and the second structural member 300 can be a screw connection. Furthermore, the elastic member 2 is sleeved on the second segment 12, and the crest segment 23 and trough segment 24 are alternately connected to form the elastic member 2. This creates a gap between the crest segment 23 and the second segment 12, allowing the elastic member 2 to deform radially along the mounting hole and be squeezed into the mounting hole of the first structural member 200.

[0052] The first structural member 200 is connected to the connecting rod 1, and the second structural member 300 is connected to the elastic member 2. The elastic member 2 is sleeved on the second segment 12 of the connecting rod 1, thereby connecting to the connecting rod 1. In other words, the first structural member 200 and the second structural member 300 can be connected to the elastic member 2 through the connecting rod 1. The structural design of the connection structure 100 proposed in this application is simpler and easier to install than the prior art.

[0053] Please see Figure 3 In some embodiments, the crest segment 23 and trough segment 24 are alternately connected in a ring structure along the circumference of the mounting hole. The alternating connection of the crest segment 23 and trough segment 24 forms a ring structure, thereby creating the cylindrical structure of the elastic component 2. During actual installation, the elastic component 2 is fitted onto the second segment 12 of the connecting rod 1. The trough segment 24 of the elastic component 2 can fit snugly against the connecting rod 1, while the crest segment 23 of the elastic component 2 will have a certain gap with the connecting rod 1. Therefore, when the elastic component 2 is inserted into the mounting hole, the crest segment 23 can contract radially inward along the connecting rod 1, allowing the elastic component 2 to be squeezed into the mounting hole.

[0054] Of course, the trough section 24 can also be spaced apart from the second section 12 of the connecting rod 1, thus allowing the elastic component 2 to undergo a greater degree of elastic contraction. In fact, the elastic component 2 can be set as a corrugated spring. The structure of the corrugated spring itself is more in line with the structural characteristics of the crest section 23 and the trough section 24, and using a corrugated spring as the elastic component 2 can save development costs and reduce production costs.

[0055] Please see Figure 4 In another embodiment, the crest segments 23 and trough segments 24 are alternately connected in a ring shape along the axial direction of the mounting hole. Each crest segment 23 and each trough segment 24 are arranged in a ring, and the crest segments 23 and trough segments 24 are alternately connected along the axial direction of the mounting hole, thereby forming a barrel-shaped structure of the elastic component 2. In actual installation, the crest segments 23 in the elastic component 2 are spaced apart from the connecting rod 1. When the elastic component 2 is inserted into the mounting hole, the crest segments 23 are squeezed by the sidewall of the mounting hole, causing the crest segments 23 to elastically contract inward along the radial direction of the mounting hole, thereby squeezing the elastic component 2 into the mounting hole and connecting with the first structural member 200.

[0056] Please see Figure 1 and Figure 5 In some embodiments, each crest segment 23 is provided with a connecting portion 25 for connecting to the inner wall of the mounting hole. During installation, the elastic member 2 is inserted into the mounting hole through elastic expansion and contraction. After the elastic member 2 is installed, its rebound causes the crest segment 23 and the trough segment 24 to abut against the inner wall of the mounting hole, thereby preventing the elastic member 2 from coming out of the mounting hole. However, when a high connection strength is required between the first structural member 200 and the second structural member 300, simply relying on the elastic member 2 to abut against the inner wall of the mounting hole may not meet the strength requirements. Therefore, in this embodiment, each crest segment 23 is also provided with a connecting portion 25. When the elastic member 2 is inserted into the mounting hole, the connecting portion 25 can connect to the inner wall of the mounting hole, thereby improving the connection strength between the elastic sleeve and the first structural member 200.

[0057] In practical applications, the first structural member 200 can be provided with a mating part corresponding to the connecting part 25 on the inner wall of the mounting hole, so that the elastic sleeve and the first structural member 200 can be connected and mated through the connecting part 25 and the mating part, thereby further improving the connection strength between the elastic sleeve and the first structural member 200.

[0058] In some embodiments, the sidewall of the mounting hole is provided with a first tooth 210. The connection structure 100 also includes a connection portion 25 disposed on the outside of the elastic member 2, the connection portion 25 including a second tooth 251 corresponding to the first tooth 210, and the elastic member 2 is connected to the first structural member 200 by means of the second tooth 251 and the first tooth 210.

[0059] The mounting hole has a first tooth 210 on its side wall, while the elastic member 2 has a second tooth 251 on its side wall. When the elastic member 2 is inserted into the mounting hole, the second tooth 251 engages with the first tooth 210, thereby tightly connecting the elastic member 2 with the first structural member 200. In actual installation, the actual structure of the first tooth 210 and the second tooth 251 can be adjusted according to usage requirements. For example, the first tooth 210 and the second tooth 251 can be annular teeth or threaded teeth. In addition, there are many specific embodiments of the connecting part 25. The connecting part 25 can be set as a positioning protrusion, and the first tooth 210 can be correspondingly adjusted to be a mating groove on the inner wall of the mounting hole. When the elastic member 2 is inserted into the mounting hole, the positioning protrusion will connect and engage with the mating groove.

[0060] Please see Figure 4 and Figure 9 In one embodiment of this application, the second teeth 251 are continuously arranged on the outer periphery of the elastic member 2. In this embodiment, the connecting structure 100 is connected to the first structural member 200 through the elastic member 2, and when the elastic member 2 is inserted into the mounting hole on the first structural member 200, the second teeth 251 will engage with the first teeth 210 in the mounting hole. Therefore, the second teeth 251 can be continuously arranged on the outer periphery of the elastic member 2, thereby enabling the elastic member 2 to be more stably connected to the first structural member 200.

[0061] In another embodiment of this application, the second teeth 251 are spaced apart on multiple crest segments 23 of the elastic member 2, thereby making the second teeth 251 closer to the inner wall of the mounting hole relative to the trough segments 24, that is, closer to the first teeth 210, thus making the connection between the second teeth 251 and the first teeth 210 tighter. In specific applications, the specific arrangement of the second teeth 251 can be selected and adjusted according to actual needs.

[0062] Please see Figure 6 In some embodiments, along the axial direction of the elastic member 2 from the first segment 11 to the second segment 12, the radial dimension of the second segment 12 gradually increases. The elastic member 2 has a fitting hole adapted to the second segment 12.

[0063] The radial dimension of the second segment 12 gradually increases, meaning that the radial dimension of the second segment 12 near the mounting hole is larger. The elastic member 2 has a fitting hole that matches the second segment 12, so the elastic member 2 can be fitted and installed on the second segment 12. In actual installation, the mounting hole can be configured to correspond to the structure of the second segment 12, so that the inner diameter of the mounting hole on the side away from the first structural member 200 is larger.

[0064] During installation, the second segment 12 and the elastic component 2 are inserted together into the mounting hole of the first structural member 200. After installation, when the second segment 12 and the elastic component 2 are moved out of the mounting hole by an external force, because the end of the second segment 12 and the elastic component 2 away from the second structural member 300 is larger, the second segment 12 and the elastic component 2 will experience relatively greater resistance, making it difficult for the second segment 12 and the elastic component 2 to fall out of the mounting hole, thereby increasing the connection strength between the elastic component 2 and the first structural member 200.

[0065] In some embodiments, the outer diameter of the elastic member 2 remains constant from the first segment 11 to the second segment 12 along the axial direction of the elastic member 2. The radial dimension of the second segment 12 gradually increases, and the elastic member 2 has a sleeve hole adapted to the second segment 12. Therefore, the inner diameter of the elastic member 2 gradually increases along the axial direction of the elastic member 2 from the end away from the first structural member 200 to the end close to the first structural member 200.

[0066] In this embodiment, the wall thickness of the elastic member 2 gradually decreases from the first segment 11 to the second segment 12 along the axial direction of the elastic member 2, thereby keeping the outer diameter of the elastic member 2 constant. Keeping the outer diameter of the elastic member 2 constant allows the inner diameter of the mounting hole to remain constant, which simplifies the machining of the mounting hole and reduces costs.

[0067] Please see Figures 7 to 8 In some embodiments, the elastic member 2 has a first end and a second end disposed opposite to each other along the axial direction of the elastic member 2. A first contraction opening 26 is provided through the first end 21 of the elastic member 2 radially, and a second contraction opening 28 is provided through the second end 22 of the elastic member 2 radially. In the axial direction of the elastic member 2, the sum of the length of the first contraction opening 26 and the length of the second contraction opening 28 is greater than or equal to the length of the elastic member 2.

[0068] The elastic member 2 is provided with a first contraction opening 26 and a second contraction opening 28, which gives the elastic member 2 a certain contraction space in the radial direction. Therefore, when the elastic member 2 is inserted into the mounting hole on the first structural member 200, the elastic member 2 can contract radially when squeezed by the side wall of the mounting hole. Through the contraction of the elastic member 2, the elastic member 2 can be inserted into the mounting hole. After the elastic member 2 is inserted into the mounting hole, the connecting part 25 provided on the elastic member 2 will connect with the inner wall of the mounting hole, thereby connecting the elastic member 2 with the first structural member 200.

[0069] Along the axial direction of the elastic member 2, the sum of the lengths of the first contraction opening 26 and the second contraction opening 28 is greater than or equal to the length of the elastic member 2. That is, the elastic member 2 has contraction space at any part of its axial direction, so the elastic member 2 can elastically contract at all parts of its axial direction, thereby enabling the elastic member 2 to meet more usage requirements and making the connection effect of the connection structure 100 better.

[0070] Please see Figure 7 In some embodiments, the width of the first contraction opening 26 is greater than the width of the second contraction opening 28 along the circumferential direction of the elastic member 2. The elastic member 2 actually ensures its contraction space by opening the first contraction opening 26 and the second contraction opening 28. Therefore, the width of the first contraction opening 26 located at the first end 21 along the circumferential direction of the elastic member 2 should be greater than the width of the second contraction opening 28 located at the second end 22. This allows the area near the first end 21 to have a larger contraction space than the area near the second end 22, enabling the elastic member 2 to meet more usage requirements and improving the connection effect of the connecting structure 100.

[0071] Please see Figure 8 In some embodiments, the number of first contraction openings 26 is greater than the number of second contraction openings 28. The elastic member 2 actually ensures its contraction space by opening the first contraction openings 26 and the second contraction openings 28. Therefore, the number of first contraction openings 26 located at the first end 21 is greater than the number of second contraction openings 28 located at the second end 22, resulting in a larger contraction space in the area closer to the first end 21 compared to the area closer to the second end 22. This allows the elastic member 2 to meet more usage requirements and improves the connection effect of the connection structure 100.

[0072] Please see Figure 10 In some embodiments, the elastic member 2 has a first end 21 and a second end 22 disposed opposite to each other along the axial direction of the elastic member 2. A first contraction opening 26 is provided through the first end 21 of the elastic member 2 in the radial direction, and the size of the first contraction opening 26 in the radial direction of the elastic member 2 gradually increases from the second end 22 to the first end 21.

[0073] In practical applications, the elastic component 2 needs to be inserted into the mounting hole on the first structural component 200. The first end 21 will contact the first structural component 200 first and be inserted into the mounting hole first. Therefore, during the process of inserting the elastic component 2 into the mounting hole, the area near the first end 21 will remain in an elastically contracted state. Thus, compared to the area near the second end 22, the area near the first end 21 requires a larger contraction space.

[0074] Therefore, in this embodiment, a first contraction opening 26 is provided through the first end 21 of the elastic member 2 along the radial direction of the elastic member 2, thereby increasing the contraction space in the region near the first end 21 of the elastic member 2. Furthermore, the size of the first contraction opening 26 gradually increases in the radial direction of the elastic member 2, so the contraction space of the elastic member 2 can gradually increase, thereby making the installation of the elastic member 2 more convenient.

[0075] Please see Figure 2 Each trough segment 24 abuts against the connecting rod 1. In practical applications, the first structural member 200 and the second structural member 300 need to be connected by multiple connecting structures 100. Therefore, the connecting structures 100 require high installation accuracy to avoid misalignment. In this embodiment, during the installation of the connecting structure 100, each crest segment 23 abuts against the side wall of the mounting hole, while each trough segment 24 abuts against the connecting rod 1. This prevents the elastic component 2 from moving easily, thus reducing the possibility of misalignment during installation and ensuring the installation accuracy of the connecting structure 100.

[0076] Please see Figure 1 and Figure 5 In some embodiments, a flange 121 is provided at the end of the connecting rod 1 near the second segment 12. The radial dimension of the flange 121 is larger than the inner diameter of the elastic member 2 to prevent the elastic member 2 from disengaging from the second segment 12. During installation, the elastic member 2 is inserted into the mounting hole through elastic expansion and contraction. After the elastic member 2 is installed, its rebound will cause the crest segment 23 and trough segment 24 to abut against the inner wall of the mounting hole, thereby preventing the elastic member 2 from coming out of the mounting hole.

[0077] In practical applications, the required connection strength between the first structural member 200 and the second structural member 300 may be high, and the elastic member 2, simply by abutting against the inner wall of the mounting hole, may not be able to meet the required connection strength. Therefore, in this embodiment, a flange 121 is provided at the end of the connecting rod 1 near the second segment 12, and the radial dimension of the flange 121 is larger than the inner diameter of the elastic member 2, thereby preventing the elastic member 2 from detaching from the second segment 12, thus increasing the connection strength between the first structural member 200 and the second structural member 300.

[0078] In some embodiments, the flange 121 has a limiting surface 121a on the side near the elastic member 2, and the elastic member 2 has a mating surface 27 corresponding to the limiting surface 121a, the mating surface 27 being located at one end near the flange 121. The limiting surface 121a extends obliquely toward the interior of the elastic member 2, and the mating surface 27 extends obliquely toward the exterior of the elastic member 2 to mat with the limiting surface 121a.

[0079] When the first structural member 200 and the second structural member 300 are subjected to external force, the elastic member 2 may move toward the second structural member 300, causing the elastic member 2 to detach from the first structural member 200. Therefore, in this embodiment, a limiting surface 121a is provided on the flange 121, and a contact surface 27 is provided on the elastic member 2 corresponding to the limiting surface 121a. When the elastic member 2 moves toward the second structural member 300, the limiting surface 121a will push against the contact surface 27, thereby causing the elastic member 2 to be subjected to a force along the radial direction of the mounting hole. Under the action of the limiting surface 121a, the elastic member 2 will expand outward toward the inner wall of the mounting hole, making it more difficult for the elastic member 2 to leave the mounting hole, thus making the connection between the elastic member 2 and the first structural member 200 tighter.

[0080] In some embodiments, the elastic member 2 has 4 or more crest segments 23 and 24 or fewer crest segments 23. When the number of crest segments 23 is large, the elastic force of the elastic member 2 will be relatively large, but the distance between the crest segments 23 and the connecting rod 1 will be relatively small. This results in a smaller range of elastic contraction of the elastic member 2, thus making the installation of the elastic member 2 more difficult. When the number of crest segments 23 is small, the elastic force of the elastic member 2 will be relatively small, but the distance between the crest segments 23 and the connecting rod 1 will be relatively large. This results in a larger range of elastic contraction of the elastic member 2, thus making the installation of the elastic member 2 easier.

[0081] Therefore, in practical applications, the number of wave crest segments 23 in the elastic component 2 should not be too many or too few. In this embodiment, the number of wave crest segments 23 is greater than or equal to 4 and less than or equal to 24, which is a suitable number. In this embodiment, the elastic force of the elastic component 2 can meet the usage requirements of the connection structure 100, and the installation difficulty of the elastic component 2 is not too high, ensuring the normal installation of the elastic component 2.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent.
