In the prior art, a building connection structure is disclosed, wherein the building connection structure is formed by filling materials in a mounting hole of a building structural member, and then the connection structure is connected with the building structural member in an interference fit manner. However, the existing connection structure is difficult to install and complicated to operate.

The inventor of the application found from research that the construction connection structure in the prior art needs to be filled with materials in the mounting holes facing the construction structure, so that the mounting of the connection structure is difficult and the operation is quite complex. The inventors of the present application therefore propose a connection structure that enables direct connection of a first structural member to a second structural member.

In view of this, this application proposes a connection structure, and it is comparatively difficult to aim at solving current connection structure's installation, the comparatively complicated problem of operation. Fig. 1 to 10 are schematic structural views of one embodiment of a connection structure proposed in the present application.

Referring to fig. 1 and 2, a connecting structure 100 of the present disclosure is used for connecting a first structural member 200 and a second structural member 300, the first structural member 200 has a mounting hole, and the connecting structure 100 includes a connecting rod 1 and an elastic component 2. The connecting rod 1 includes a first segment 11 and a second segment 12 sequentially connected along an axial direction of the connecting rod 1, and the first segment 11 is used for being connected with the second structural member 300.

The elastic component 2 is the tube-shape setting, and the second section 12 is located to the elastic component 2 cover, and includes a plurality of crest sections 23 and a plurality of trough section 24, and crest section 23 and trough section 24 connect in turn to make the elastic component 2 take place deformation along the radial of mounting hole and squeeze into in the mounting hole of first structure 200, and connect in the inner wall of mounting hole.

In the technical solution of the present application, the connection structure 100 is connected to the second structural member 300 through the connection rod 1 and connected to the first structural member 200 through the elastic member 2. The first section 11 of the connecting rod 1 is used for being connected with the second structural member 300, and the specific connection mode of the first section 11 and the second structural member 300 can be screw connection. In addition, the elastic member 2 is sleeved on the second section 12, and the crest sections 23 and the trough sections 24 are connected alternately to form the elastic member 2, so that a gap exists between the crest sections 23 and the second section 12, and the elastic member 2 can deform along the radial direction of the mounting hole and squeeze into the mounting hole of the first structural member 200.

The first structural member 200 is connected to the connecting rod 1, the second structural member 300 is connected to the elastic member 2, and the elastic member 2 is sleeved on the second section 12 of the connecting rod 1, so as to be connected to the connecting rod 1. That is, the first structural member 200 and the second structural member 300 can be connected with the elastic member 2 through the connection rod 1. The structural design of the connection structure 100 proposed in the present application is simpler than the prior art, and the installation is more convenient.

Referring to FIG. 3, in some embodiments, the peak segments 23 and the trough segments 24 are alternately connected in a ring-like configuration along the circumference of the mounting hole. The peak sections 23 and the trough sections 24 are alternately connected to form a ring structure, thereby forming a cylindrical structure of the elastic member 2. In actual installation, the elastic component 2 is sleeved on the second section 12 of the connecting rod 1, the trough section 24 of the elastic component 2 can be attached to the connecting rod 1, and the crest section 23 of the elastic component 2 can have a certain gap with the connecting rod 1. Thus, when the elastic member 2 is inserted into the mounting hole, the peak section 23 can be contracted inward in the radial direction of the connecting rod 1, so that the elastic member 2 can be pressed into the mounting hole.

Of course, the trough sections 24 may also be spaced from the second sections 12 of the connecting rod 1, thus enabling a greater degree of elastic contraction of the elastic member 2. In practice, the elastic member 2 may be configured as a corrugated spring, and the corrugated spring is configured to conform to the structural features of the crest segment 23 and the trough segment 24, and the use of the corrugated spring as the elastic member 2 can save development cost and reduce production cost.

Referring to fig. 4, in another embodiment, the peak sections 23 and the trough sections 24 are alternately connected in a ring-like structure along the axial direction of the mounting hole. Each peak segment 23 and each trough segment 24 are arranged in a ring shape, and the peak segments 23 and the trough segments 24 are alternately connected along the axial direction of the mounting hole, thereby forming a barrel-shaped structure of the elastic member 2. During actual installation, the peak sections 23 in the elastic component 2 are arranged at intervals with the connecting rod 1, and when the elastic component 2 is inserted into the mounting hole, the peak sections 23 are extruded by the side walls of the mounting hole, so that the peak sections 23 elastically shrink inwards along the radial direction of the mounting hole, and the elastic component 2 is extruded into the mounting hole to be connected with the first structural component 200.

Referring to fig. 1 and 5, in some embodiments, each peak 23 is provided with a connecting portion 25, and the connecting portion 25 is used to connect with an inner wall of the mounting hole. When the elastic member 2 is mounted, it is inserted into the mounting hole by elastic expansion and contraction. When the elastic member 2 is installed, the resilience of the elastic member 2 can make the crest section 23 and the trough section 24 respectively abut against the inner wall of the installation hole, thereby preventing the elastic member 2 from falling out of the installation hole. However, when a high strength of connection is required between the first structural member 200 and the second structural member 300, the strength requirement may not be met by only holding the elastic member 2 against the inner wall of the mounting hole. Therefore, in the present embodiment, a connection portion 25 is further provided on each peak section 23, and when the elastic member 2 is inserted into the mounting hole, the connection portion 25 can be connected with the inner wall of the mounting hole, thereby improving the connection strength between the elastic sleeve and the first structural member 200.

In practical application, the first structural member 200 may be provided with a mating portion corresponding to the connecting portion 25 on the inner wall of the mounting hole, so that the elastic sleeve and the first structural member 200 complete connection and mating with the mating portion through the connecting portion 25, and the connection strength between the elastic sleeve and the first structural member 200 is further improved.

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

The first teeth 210 are provided on the side wall of the mounting hole, and the second teeth 251 are provided on the side wall of the elastic member 2, and when the elastic member 2 is inserted into the mounting hole, the second teeth 251 can be engaged with the first teeth 210, so that the elastic member 2 is tightly connected with the first structural member 200. In actual setting, the actual structures of the first teeth 210 and the second teeth 251 can be adjusted according to the use requirement. For example, the first teeth 210 and the second teeth 251 may be annular teeth or screw teeth. In addition, there are various embodiments of the connecting portion 25, the connecting portion 25 may be configured as a positioning protrusion, and the first tooth 210 may be correspondingly adjusted to be disposed in a mating groove on the inner wall of the mounting hole at this time, and when the elastic member 2 is inserted into the mounting hole, the positioning protrusion is connected to and mated with the mating groove.

Referring to fig. 4 and 9, in an embodiment of the present application, the second teeth 251 are continuously disposed on the outer periphery of the elastic member 5. In this embodiment, the connection structure 100 is connected to the first structural member 200 through the elastic member 2, and the second teeth 251 are engaged with the first teeth 210 in the mounting hole when the elastic member 2 is inserted into the mounting hole in the first structural member 200. The second teeth 251 may thus be continuously disposed at the outer circumference of the elastic member 2, thereby enabling the elastic member 2 to be more stably coupled with the first structural member 200.

In another embodiment of the present application, the second teeth 251 are disposed on the plurality of peak segments 23 of the elastic member 2 at intervals, so that the second teeth 251 are closer to the inner wall of the mounting hole, that is, closer to the first teeth 210, than the valley segments 24, so that the second teeth 251 are more tightly connected to the first teeth 210. In a specific application, the specific layout manner of the second teeth 251 can be selected and adjusted according to actual requirements.

Referring to fig. 6, in some embodiments, the radial dimension of the second segment 12 increases gradually from the first segment 11 to the second segment 12 along the axial direction of the elastic member 2. The elastic part 2 is provided with a sleeved hole matched with the second section 12.

The radial dimension of the second section 12 increases gradually, that is to say the radial dimension of the end of the second section 12 near the mounting hole is larger. The elastic member 2 has a socket hole therein adapted to the second section 12, so that the elastic member 2 can be fitted to the second section 12. In practice, the mounting holes may be configured to correspond to the configuration of the second section 12 such that the inner diameter of the side of the mounting holes remote from the first structural member 200 is larger.

When the installation is performed, the second segment 12 and the elastic member 2 are inserted into the installation hole of the first structural member 200 together. When the second section 12 and the elastic component 2 are moved out of the mounting hole by the external force after the mounting is completed, the second section 12 and the elastic component 2 are subjected to relatively larger resistance because the second section 12 and the elastic component 2 are larger in size at the end far away from the second structural member 300, so that the second section 12 and the elastic component 2 are difficult to fall out from the mounting hole, and the connection strength of the elastic component 2 and the first structural member 200 is increased.

In some embodiments, the outer diameter of the resilient member 2 remains unchanged from the first segment 11 to the second segment 12 along the axial direction of the resilient member 2. The radial dimension of the second section 12 gradually increases, and the elastic member 2 has a sleeved hole matched with the second section 12, so that the inner diameter of the elastic member 2 gradually increases from one end far from the first structural member 200 to one end close to the first structural member 200 along the axial direction of the elastic member 2.

In the present embodiment, the wall thickness of the elastic member 2 gradually decreases from the first section 11 to the second section 12 in the axial direction of the elastic member 2, so that the outer diameter of the elastic member 2 remains unchanged. The outer diameter of the elastic part 2 is kept unchanged, so that the inner diameter of the mounting hole can be kept unchanged, the inner diameter of the mounting hole is kept unchanged, the processing of the mounting hole can be simpler, and the cost is lower.

Referring to fig. 7 to 8, in some embodiments, the elastic member 2 has a first end and a second end disposed opposite to each other along an axial direction of the elastic member 2. The first end 21 of the elastic member 2 is provided with a first shrinkage opening 26 along the radial direction of the elastic member 2, the second end 22 of the elastic member 2 is provided with a second shrinkage opening 28 along the radial direction of the elastic member 2, and the sum of the length of the first shrinkage opening 26 and the length of the second shrinkage opening 28 is greater than or equal to the length of the elastic member 2 along the axial direction of the elastic member 2.

The elastic member 2 is provided with a first constricted opening 26 and a second constricted opening 28, which makes the elastic member 2 have a certain constricted space in the radial direction of the elastic member 2. Therefore, when the elastic member 2 is inserted into the mounting hole of the first structural member 200, the elastic member 2 can be contracted in the radial direction of the elastic member 2 when being pressed by the side wall of the mounting hole. By the contraction of the elastic member 2, the elastic member 2 can be inserted into the mounting hole. When the elastic member 2 is inserted into the mounting hole, the connection portion 25 provided on the elastic member 2 is connected to the inner wall of the mounting hole, so that the elastic member 2 is connected to the first structural member 200.

The sum of the length of the first constricted opening 26 and the length of the second constricted opening 28 is greater than or equal to the length of the elastic member 2 in the axial direction of the elastic member 2. That is, any part of the elastic member 2 in the axial direction thereof has a contraction space, and thus the elastic member 2 can elastically contract at all portions in the axial direction thereof, thereby enabling the elastic member 2 to meet more use demands and enabling the connecting structure 100 to have a better connecting effect.

Referring to fig. 7, in some embodiments, the width of the first constricted opening 26 is greater than the width of the second constricted opening 28 in the circumferential direction of the elastic member 2. The elastic member 2 actually guarantees its own shrink space by providing the first shrink opening 26 and the second shrink opening 28, so that the width of the first shrink opening 26 located at the first end 21 along the circumferential direction of the elastic member 2 is larger than the width of the second shrink opening 28 located at the second end 22, so that the area close to the first end 21 is relatively close to the second end 22 and has a larger shrink space, so that the elastic member 2 can meet more use requirements and the connection effect of the connection structure 100 is better.

Referring to fig. 8, in some embodiments, the number of first constricting openings 26 is greater than the number of second constricting openings 28. The elastic member 2 actually guarantees the shrink space by opening the first shrink openings 26 and the second shrink openings 28, so that the number of the first shrink openings 26 at the first end 21 is larger than that of the second shrink openings 28 at the second end 22, so that the area close to the first end 21 is relatively close to the second end 22 and has larger shrink space, thereby the elastic member 2 can meet more use requirements and the connecting effect of the connecting structure 100 is better.

Referring to fig. 10, in some embodiments, the elastic member 2 has a first end 21 and a second end 22 disposed opposite to each other along an axial direction of the elastic member 2, a first shrinkage opening 26 is formed on the first end 21 of the elastic member 2 along a radial direction of the elastic member 2, and a size of the first shrinkage opening 26 in the radial direction of the elastic member 2 gradually increases from the second end 22 to the first end 21.

In a specific application, the elastic member 2 needs to be inserted into the mounting hole of the first structural member 200, and the first end 21 will contact the first structural member 200 before being inserted into the mounting hole. The region near the first end 21 is thus maintained in an elastically contracted state during insertion of the elastic member 2 into the mounting hole, and thus a region relatively near the second end 22 requires a larger contraction space.

In the present embodiment, therefore, the first end 21 of the elastic member 2 is provided with the first constricted opening 26 penetrating therethrough in the radial direction of the elastic member 2, thereby increasing the constricted space in the region near the first end 21 of the elastic member 2. And the size of the first constricted opening 26 in the radial direction of the elastic member 2 is gradually increased, so that the constricted space of the elastic member 2 can be gradually increased, thereby making the installation of the elastic member 2 more convenient.

Referring to fig. 2, each of the valley sections 24 abuts the connecting rod 1. In a specific application, the first structural member 200 and the second structural member 300 need to be connected through a plurality of connecting structures 100, so that the connecting structures 100 need to be installed with high installation accuracy to avoid dislocation. In the present embodiment, when the connection structure 100 is installed, each peak segment 23 will abut against the side wall of the installation hole, and each trough segment 24 will abut against the connecting rod 1, so that the elastic component 2 will not easily move, and thus the possibility of dislocation of the connection structure 100 during installation is smaller, and the installation accuracy of the connection structure 100 is ensured.

Referring to fig. 1 and 5, in some embodiments, a flange 121 is disposed at an end of the connecting rod 1 near the second section 12, and a radial dimension of the flange 121 is greater than an inner diameter of the elastic member 2 to limit the elastic member 2 from being separated from the second section 12. When the elastic member 2 is mounted, it is inserted into the mounting hole by elastic expansion and contraction. When the elastic member 2 is installed, the resilience of the elastic member 2 can make the crest section 23 and the trough section 24 respectively abut against the inner wall of the installation hole, thereby preventing the elastic member 2 from falling out of the installation hole.

In practical applications, the connection strength required by the first structural member 200 and the second structural member 300 may be high, and the elastic member 2 may not meet the connection strength required by the first structural member 200 and the second structural member 300 only by abutting against the inner wall of the mounting hole. In the present embodiment, therefore, the connecting rod 1 is provided with the flange 121 near the end of 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 being detached from the second segment 12, thereby increasing the connection strength of the first structural member 200 and the second structural member 300.

In some embodiments, a limiting surface 121a is disposed on a side of the flange 121 near the elastic member 2 toward the elastic member 2, and the elastic member 2 has an abutment surface 27 disposed corresponding to the limiting surface 121a, where the abutment surface 27 is disposed near one end of the flange 121. The stopper surface 121a extends obliquely toward the inside of the elastic member 2, and the abutment surface 27 extends obliquely toward the outside of the elastic member 2 so as to abut against the stopper surface 121 a.

When the first structural member 200 and the second structural member 300 are subjected to external force, the elastic component 2 may be moved towards the second structural member 300, so that the elastic component 2 is separated from the first structural member 200. In this embodiment, therefore, the flange 121 is provided with a limiting surface 121a, and the elastic member 2 is provided with an abutment surface 27 corresponding to the limiting surface 121 a. When the elastic component 2 moves towards the second structural component 300, the limiting surface 121a pushes against the abutting surface 27, so that the elastic component 2 receives a force along the radial direction of the mounting hole. The elastic member 2 expands outwards towards the inner wall of the mounting hole under the action of the limiting surface 121a, so that the elastic member 2 is more difficult to leave the mounting hole, and the connection between the elastic member 2 and the first structural member 200 is more compact.

In some embodiments, the number of peak sections 23 of the elastic member 2 is 4 or more and 24 or less. When the number of peak sections 23 is large, the elastic force of the elastic member 2 will be relatively large, but the distance between the peak sections 23 and the connecting rod 1 will be relatively small, which results in a smaller amplitude of elastic contraction of the elastic member 2, and thus the difficulty of installation of the elastic member 2 is high. When the number of peak sections 23 is small, the elastic force of the elastic member 2 will be relatively small, but the distance between the peak sections 23 and the connecting rod 1 will be relatively large, which results in a large amplitude of elastic contraction of the elastic member 2, and thus the difficulty of installation of the elastic member 2 is low.

Therefore, in practical use, the number of peak portions 23 in the elastic member 2 cannot be too large nor too small. In this embodiment, the number of the peak segments 23 is 4 or more and 24 or less, and the number of the peak segments 23 is suitable. In this embodiment, the elastic force of the elastic component 2 can meet the use requirement of the connection structure 100, and the installation difficulty of the elastic component 2 is not too high, so that the normal installation of the elastic component 2 can be ensured.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the utility model. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
