Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a rotary connector for bamboo splicing. Background Technology

[0002] In both traditional architecture and modern landscape design, bamboo, with its eco-friendly, lightweight, and high-strength properties, has become an ideal material for constructing bamboo roof structures. Bamboo roof structures, with their unique shapes and natural beauty, are widely used in garden landscapes, leisure spaces, and other architectural applications.

[0003] However, in the process of constructing a bamboo roof, bamboo stalks need to be spliced ​​together at different angles to form a specific shape. Most existing bamboo connectors are fixed-angle structures, which cannot meet the complex and ever-changing angle adjustment requirements of bamboo roofs. Although some adjustable connectors can achieve certain angle changes, they are prone to shifting or misaligning due to changes in the bamboo's angle during adjustment. Workers need to frequently adjust the position of the connectors to prevent them from loosening at the connection with the bamboo, thus making the structure more stable after splicing.

[0004] Therefore, it is necessary to develop a rotating connector that can easily adjust the splicing angle of bamboo and ensure a stable connection, in order to solve the technical problems currently faced in the construction of bamboo structure roofs. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the aforementioned rotating connector for bamboo splicing, this utility model is proposed.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a rotating connector for splicing bamboo, including a combination ring, which is formed by a pair of rings and used to fix bamboo. Each ring has an ear plate fixed on both sides, and the top of the ear plate is bent to form a support plate.

[0008] Insert holder, including:

[0009] A long bolt is movably inserted through the support plate, and its axial length can penetrate radially along the second bamboo.

[0010] A pair of pressure plates, mounted on long bolts, are located on both sides of bamboo two. Each pressure plate includes:

[0011] A pair of wrapping boards are positioned opposite each other on both sides of the pressure plate and extend toward the outer wall of the bamboo.

[0012] The friction-enhancing pad is embedded in the wrapping plate. Its outer side is serrated and protrudes above the surface of the wrapping plate. When the friction-enhancing pad is deformed by the pressure of the second bamboo and the second bamboo does not contact the surface of the wrapping plate, the long bolt is in a pre-tightened state. The combined ring can rotate the first bamboo around the long bolt as an axis, and the pressure plate is always in contact with the second bamboo under the control of the friction-enhancing pad.

[0013] In a preferred embodiment of the rotating connector for bamboo splicing described in this utility model, when multiple wrapping plates are attached to the surface of the second bamboo, the long bolt is in a tightened state, locking the relative positions of the first bamboo and the second bamboo.

[0014] As a preferred embodiment of the rotating connector for bamboo splicing described in this utility model, a filling pad is provided at the transition position of the upper surface of the pressure plate and the wrapping plate, and the outer wall of the filling pad is an arc surface that can fit the outer wall of the bamboo.

[0015] In a preferred embodiment of the rotating connector for bamboo splicing described in this utility model, the included angle between the wrapping plate and the pressure plate is 130~160°.

[0016] In a preferred embodiment of the rotating connector for bamboo splicing described in this utility model, the two collars are locked in relative position by short bolts on the ear plate.

[0017] In a preferred embodiment of the rotating connector for bamboo splicing described in this utility model, the included angle between the support plate and the ear plate is 80~100°.

[0018] The beneficial effects of this utility model are as follows: the combination of the set combination ring and the insertion frame makes it easy to splice bamboo, and the relative angle of the bamboo can be adjusted according to the actual needs of the installation site. At the same time, the wrapping plates and friction pads set on both sides of the pressure plate work together to increase the friction between them and the bamboo, further preventing slippage, making the overall installation simpler, and improving the structural stability of the bamboo after splicing.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Reference Figures 1-4 This invention provides a rotating connector for splicing bamboo, comprising a combination ring consisting of a pair of collars 1 for fixing bamboo. Each collar 1 has an ear plate 11 fixed on both sides. The two collars 1 are locked in relative position by short bolts 12 on the ear plates 11, making it easier to assemble and disassemble the collars 1 and adjust the tightness of the combination ring on the bamboo according to actual needs, while ensuring the reliability of the connection. The top of the ear plate 11 is bent to form a support plate 13 with a bending angle of 80~100°. The support plate 13 provides a connection platform and provides an installation base for the insertion frame 2.

[0030] The insert bracket 2, including a long bolt 21, is movably mounted on the support plate 13, and its axial length can penetrate radially along the bamboo 2.

[0031] A pair of pressure plates 22 are mounted on long bolts 21 and located on both sides of the bamboo stalk. Each pressure plate 22 includes:

[0032] A pair of wrapping plates 221 are disposed opposite each other on both sides of the pressure plate 22 and extend toward the outer wall of the second bamboo. The angle between the wrapping plates 221 and the pressure plate 22 is 130~160°. The extended design and specific angle of the wrapping plates 221 increase the contact area with the bamboo and improve the fixing effect. In addition, the extended design of the wrapping plates 221 will abut against the outer wall of the second bamboo when the pressure plate 22 deflects, thereby limiting the deflection range of the pressure plate 22.

[0033] A filling pad 223 is provided at the transition position between the upper surface of the pressure plate 22 and the wrapping plate 221, and the outer wall of the filling pad 223 is an arc surface that can fit the outer wall of the bamboo. The arc surface of the filling pad 223 can effectively reduce stress concentration, enhance the stability of the connection, and improve the adaptability to bamboo of different diameters.

[0034] The friction-enhancing pad 222 is embedded in the wrapping plate 221. Its outer side is serrated, protruding above the surface of the wrapping plate 221. When the friction-enhancing pad 222 is deformed by the pressure of the second bamboo and the second bamboo is not in contact with the surface of the wrapping plate 221, the long bolt 21 is in a pre-tightened state. The combined ring can rotate the first bamboo around the long bolt 21 as an axis, and the pressure plate 22 is always in contact with the second bamboo under the control of the friction-enhancing pad 222. In the pre-tightened state of the long bolt 21, the friction of the friction-enhancing pad 222 ensures that the pressure plate 22 is in contact with the second bamboo, further preventing slippage, while allowing the combined ring to rotate the first bamboo to adjust the angle.

[0035] When multiple wrapping plates 221 are attached to the surface of bamboo two, the long bolts 21 are tightened and lock the relative positions of bamboo one and bamboo two. The friction pads 222 further enhance the friction, prevent bamboo two from slipping, and ensure the stability of the spliced ​​structure.

[0036] In summary, this bamboo splicing rotary connector, through the design of components such as the combination ring, insert frame 2, and pressure plate 22, not only achieves flexible adjustment and stable connection between bamboo sections, effectively solving the construction challenges of bamboo structure roofs, but also expands its application scenarios by setting combination rings of different sizes. Whether splicing bamboo sections together or assembling bamboo with steel cables, its structure allows for rapid completion, greatly improving the versatility and convenience of the connection, and providing an efficient and reliable connection solution for bamboo structure architecture and landscape design.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
