Description

Technical Field

[0001] This utility model relates to the field of composite material connection technology, and specifically to a novel composite material node connection structure. Background Technology

[0002] Composite materials are multiphase solid materials composed of two or more substances with different physical and chemical properties. In composite materials, there is usually one continuous phase, called the matrix, and another dispersed phase, called the reinforcing phase (reinforcing body). This combination allows composite materials to retain some characteristics of the raw materials while also exhibiting new features after combination. They have advantages such as light weight, high strength, corrosion resistance, high and low temperature resistance, and ease of processing. As the application fields of new composite materials continue to expand, the requirements for their bonding performance are also increasing. Therefore, it is necessary to develop new bonding technologies with higher bonding strength, better durability, and environmental resistance.

[0003] A search revealed that Chinese utility model patent CN220605798U discloses a splicing structure for connecting nodes. By locking and fixing the flange plates on both sides of the upper and lower connecting parts with bolts, the internal force transmission between the upper and lower connecting parts is effectively guaranteed. The internal forces at the connecting node, including bending moment and axial force, can be transferred to the lower connecting part through shearing of the connecting bolts. This ensures that the bolt holes only bear pressure and are not subjected to punching and shearing, effectively solving the problem of easy damage at the bolt holes and improving the structural strength of the connecting node.

[0004] However, in actual use, under high load or vibration conditions, the bolt connections of the above devices may loosen or fail, leading to damage at the connection nodes. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a novel composite material node connection structure, which can effectively solve the problem that bolt connections may loosen or fail, leading to damage at the connection node.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a novel composite material node connection structure, including a first profile and a second profile. A fixing plate is provided at the top of the first profile, and a fixing component is provided above the fixing plate. The fixing component includes a nut, and an extrusion plate is fixedly connected to the lower end of the nut. Two sets of identical elastic plates are provided below the extrusion plate, and the elastic plates are sleeved on the surface of a threaded sleeve. An auxiliary block is provided below the threaded sleeve, and a bolt is sleeved on the auxiliary block. An auxiliary plate is provided above the fixing component. One end of the auxiliary plate is rotatably connected to the second profile, and the second profile is snapped into the first profile by the auxiliary plate. The other end of the auxiliary plate is fixedly connected to the first profile by the fixing component.

[0008] Furthermore, the fixing plate and the first profile are fixedly connected by a fixing component.

[0009] Furthermore, the fixing plate is fixedly connected to a locking block, and the surface of the auxiliary plate is provided with a locking slot, which engages with the locking block.

[0010] Furthermore, the bolt passes through the auxiliary block, the threaded sleeve, the elastic plate, the compression plate, and the nut, and the bolt is threadedly connected to the threaded sleeve and the nut.

[0011] Furthermore, a cavity is provided between the two sets of elastic sheets, and an installation space is provided inside the auxiliary block.

[0012] Furthermore, a slider is provided on the surface of the elastic sheet, and the slider is slidably connected to a threaded sleeve.

[0013] Furthermore, mounting holes are provided on both symmetrical surfaces of the auxiliary plate near the bayonet opening, and fixing components are threaded into the mounting holes.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] I. This utility model provides additional support for the connection structure by setting a fixing component. Under high load or vibration environment, the fixing component can absorb and disperse the impact force, thereby effectively reducing the risk of loosening caused by shaking. This design enables the connection node to maintain relative stability when facing dynamic environment, extends the service life of the connection structure, and reduces maintenance costs and safety risks caused by connection failure.

[0016] Second, this utility model adopts a threaded connection method, which can easily complete the assembly or disassembly work by rotating the threaded part. This design does not require the use of complicated tools or equipment, which greatly improves the efficiency of the connection work. At the same time, the tightness of the threaded connection also enhances the firmness of the connection, ensuring the stability and reliability of the connection structure during long-term use.

[0017] Third, this utility model achieves a stable connection between the first profile 1 and the second profile 2 through the snap-fit ​​design of the fixing component, auxiliary plate 3, and snap-fit ​​block 5 with the snap-fit ​​4. The extrusion plate 15, elastic plate 11, and auxiliary block 12 in the fixing component work together to provide strong support for the connection structure. The threaded connection between the mounting hole 8 on the surface of the auxiliary plate 3 and the fixing component also provides additional stability and support for the entire connection structure. This optimized connection structure enables the connection node to withstand greater loads and improves the load-bearing capacity of the overall structure. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] A novel composite material node connection structure, see attached figure. Figures 1-6The structure includes a first profile 1 and a second profile 2. A fixing plate 18 is mounted on the top of the first profile 1, playing a crucial role in connecting the upper and lower profiles and ensuring a tight connection between the fixing assembly and the auxiliary plate 3. A fixing assembly, including a nut 10, is mounted above the fixing plate 18. A compression plate 15 is fixedly connected to the lower end of the nut 10. Two identical sets of elastic plates 11 are mounted below the compression plate 15, and these elastic plates 11 are fitted onto the surface of a threaded sleeve 17. An auxiliary block 12 is mounted below the threaded sleeve 17, and a bolt 9 is fitted onto the auxiliary block 12. The lower end of the nut 10 is fixedly connected to the compression plate 15 and the two sets of elastic plates 11, which, when fitted onto the surface of the threaded sleeve 17, provide additional elasticity and support to the entire structure, forming a solid... The core component of the fixing assembly, the elastic sheet 11, possesses a certain degree of elasticity. When the first profile 1 and the second profile 2 shake, it can deform under external force, thereby absorbing and dispersing the impact force. This elastic support allows the fixing assembly to maintain relative stability when facing dynamic environments such as shaking or vibration, reducing the risk of loosening caused by shaking. During long-term use, even under the influence of large external forces or environmental factors, the fixing assembly can maintain a relatively stable state, thereby ensuring the safety and reliability of the connection. The fixing plate 18 is fixedly connected to the first profile 1 through the fixing assembly. The fixing plate 18 is fixedly connected with a locking block 5. The surface of the auxiliary plate 3 has a locking slot 4, which engages with the locking block 5. The locking blocks 5 are matched. The included bayonet 4 allows the locking block 5 to precisely engage with it, thus achieving a stable connection between the auxiliary plate 3 and the fixing plate 18. Utilizing the engagement relationship between the bayonet 4 and the locking block 5, the connection between the first profile 1 and the second profile 2 is initially achieved. The auxiliary plate 3 is positioned above the fixing component, and the fixing component and the auxiliary plate 3 together establish a stable connection between the first profile 1 and the second profile 2. The bolt 9 passes through the auxiliary block 12, the threaded sleeve 17, the elastic plate 11, the compression plate 15, and the nut 10. The bolt 9 is threadedly connected to the threaded sleeve 17 and the nut 10. This threaded connection allows for easy assembly and disassembly; when assembly or disassembly is required, it can be completed simply by rotating the threaded component, without the need for complex tools or equipment, thus improving the connection process. This improves efficiency and reduces maintenance costs. The tight connection between various components further enhances the strength of the connection. A cavity 14 is provided between the two sets of elastic plates 11. An installation space 13 is provided inside the auxiliary block 12. A slider 16 is provided on the surface of the elastic plate 11, and the slider 16 is slidably connected to a screw sleeve 17. The cavity 14 provided between the two sets of elastic plates 11 can increase the stability of the structure in the lateral or longitudinal direction. The cavity 14 between the two sets of elastic plates 11 can effectively disperse and resist external forces, preventing the structure from deforming or being damaged due to uneven stress. One end of the auxiliary plate 3 is rotatably connected to the second profile 2. The second profile 2 is snapped between the auxiliary plate 3 and the first profile 1. The other end of the auxiliary plate 3 is fixedly connected to the first profile 1 through a fixing component.The other end of the auxiliary plate 3 is fixedly connected to the first profile 1 via a fixing component. Mounting holes 8 are provided on both symmetrical surfaces of the auxiliary plate 3 near the bayonet 4. The mounting holes 8 are threaded with fixing components, thus firmly connecting the auxiliary plate 3 to the first profile 1. The threaded connection between the mounting holes 8 and the fixing components provides additional stability and support to the entire connection structure, thereby achieving the final connection between the first profile 1 and the second profile 2.

[0029] Working principle: In use, the operator first fixes the first profile 1, and uses the fixing component to fix the fixing plate 18 to the surface of the first profile 1. Then, the second profile 2 is brought closer to the first profile 1. Then, by rotating the auxiliary plate 3, the snap 4 on the surface of the auxiliary plate 3 is engaged with the snap block 5 fixedly connected to the upper surface of the fixing plate 18. At this time, the connection between the first profile 1 and the second profile 2 is initially completed. Then, a drilling tool is used to drill holes according to the diameter of the mounting hole 8. Then, the fixing component is installed on the surface of the mounting hole 8, thereby achieving the final connection between the first profile 1 and the second profile 2.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
