Description

Technical Field

[0001] This application relates to the technical field of exhibition profiles, and particularly to a profile assembly. Background Art

[0002] In existing exhibition display systems, in order to construct a stable and flexible display structure, several profiles are generally used for horizontal and vertical connections. Between these profiles, in order to ensure the firmness and detachable nature of the connection, a connection method combining locks and bolts is usually adopted. The bolt connection method requires operators to manually align the bolts with the holes, and then use tools such as screwdrivers or wrenches to tighten them one by one. This process is not only time-consuming but also requires relatively high manual skills. Especially in exhibition environments with narrow spaces or different heights, the operation is even more difficult. Moreover, in large-scale exhibitions or complex display systems, hundreds or thousands of profiles and components may need to be connected. If all are connected using bolt locks, then the operators will have to repeatedly perform the action of tightening bolts, greatly reducing the installation efficiency.

[0003] Therefore, plug-in connectors have emerged at present. However, in order to ensure the stability and durability of the connection, plug-in connectors often use relatively heavy materials in design, such as metal alloys, etc. These materials have relatively high density and strength, but correspondingly increase the overall weight of the connector, and the manufacturing cost is also much higher than that of bolts. If the pursuit of weight reduction ignores the requirements of structural strength, it may lead to problems such as deformation and fracture of the connector during use, thus affecting its normal use and safety.

[0004] Therefore, this application is specifically proposed. Summary of the Invention

[0005] The purpose of this application is to solve the problems in the prior art that when plug-in connectors pursue stability and durability, they often lead to an increase in weight and manufacturing cost, and at the same time avoid the safety problems such as insufficient structural strength, deformation or fracture during use caused by excessive lightweight design; thus, a brand-new profile assembly is proposed, aiming to achieve structural strengthening while taking into account lightweight.

[0006] In this application, it includes several profile monomers and connection buckles; equally spaced first through holes are provided on each profile monomer; the connection buckle includes a main body frame and hook parts provided on both sides of the main body frame. The main body frame can be hung on the first through holes through the hook parts to connect two profile monomers; among them, the connection buckle includes a first reinforcing rib and a second reinforcing rib, and the first reinforcing rib and the second reinforcing rib are connected to the main body frame and are arranged to cross each other along a first direction.

[0007] In the present application, on two sides of the main body frame in the first direction, first holes penetrating the main body frame are respectively provided; the first reinforcing rib and the second reinforcing rib are respectively arranged in the two first holes.

[0008] In the present application, the cross-section of the main body frame in the first direction is a parallelogram, including two first extending bodies extending in the second direction and parallel to each other, and two second extending bodies extending in the third direction and parallel to each other; at least two hook portions are provided on each first extending body.

[0009] In the present application, two hook portions are provided on each first extending body, and the two hook portions are respectively arranged at the ends of the first extending body; the two ends of the first reinforcing rib are respectively connected to the nearer diagonal corners of the main body frame; one end of the second reinforcing rib is connected to the middle of one first extending body, and the other end is connected to the middle of the other first extending body.

[0010] In the present application, the hook portion includes a first section and a second section. The first section is connected to the first extending body, and the second section is connected to the first section and is arranged at an angle with the second section. The first section, the second section and the first extending body together form a hook groove for hooking on the first through hole.

[0011] In the present application, the hook grooves on the two first extending bodies face in opposite directions.

[0012] In the present application, second holes penetrating the main body frame are provided on two end faces of the main body frame in the second direction.

[0013] In the present application, the first through hole is a strip-shaped hole, and the width of the first through hole matches the hook portion.

[0014] In the present application, each profile monomer includes a profile main body and a plurality of first connecting portions protruding from the surface of the profile main body. The first connecting portions and the surface of the profile main body together form a card slot, and the first through holes are sequentially arranged on the profile main body corresponding to the card slots; the main body frame can be partially accommodated in the card slot and is hooked on the first through hole through the hook portion.

[0015] In the present application, on at least one adjacent surface of the surface of the profile main body where the first connecting portion is provided, a wire routing hole and a number of second through holes are provided, and the wire routing hole is arranged at the end of the profile main body.

[0016] In summary, a profile assembly provided by the present application includes a number of profile monomers and connecting fasteners, and at least has the following beneficial effects:

[0017] The equally spaced first through holes provided on each profile monomer cooperate with the hook portions of the connecting fasteners to achieve fast and convenient plug-in connection. The installation steps are simplified and the installation efficiency is improved.

[0018] In the design of the connecting buckle, the first reinforcing rib and the second reinforcing rib are cross-arranged along the first direction H, and together with the main frame form two triangular structures. The two triangular structures form a stable support network inside the connecting buckle, so that the entire buckle can maintain good shape stability when subjected to external loads. When the connecting buckle is subjected to tension or shear force, the cross-reinforcing ribs can share the stress together, reduce stress concentration in a single part, and thus improve the overall rigidity. Due to the presence of the cross-reinforcing ribs, the connecting buckle can maintain good shape stability when subjected to a large load and is not prone to deformation or breakage. This enables the connecting buckle to more reliably connect the profile monomers and ensure the structural safety of the entire profile assembly.

For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0040] As Figures 1 to 6 shown, an extrusion profile assembly 100 provided by an embodiment of the present application includes a plurality of extrusion profile monomers 10 and connecting buckles 20; wherein "a plurality" means at least two extrusion profile monomers 10; equally spaced first through holes a are provided on each extrusion profile monomer 10; specifically, the first through holes a are provided on the outer side surface of the extrusion profile monomer 10.

[0041] The connecting buckle 20 includes a main body frame 21 and hook parts 22 provided on both sides of the main body frame 21. The main body frame 21 can be hooked in the first through hole a through the hook parts 22 to connect two extrusion profile monomers 10; through the equally spaced first through holes a provided on each extrusion profile monomer 10 and in cooperation with the hook parts 22 of the connecting buckle 20, quick and convenient hooking can be achieved, thereby simplifying the installation steps, improving the installation efficiency, and reducing the skill requirements for operators.

[0042] The entire extrusion profile assembly 100 adopts a modular design, enabling flexible combination of different numbers and types of extrusion profile monomers 10 to meet various complex and changeable exhibition or display requirements. At the same time, due to the universality of the connecting buckle 20, the inventory cost and the complexity of spare parts management can be greatly reduced.

[0043] Based on the general concept of the present invention, the connecting buckle 20 includes a first reinforcing rib 23 and a second reinforcing rib 24. The first reinforcing rib 23 and the second reinforcing rib 24 are connected to the main body frame 21 and are arranged to cross each other along the first direction H.

[0044] Specifically, from the perspective along the first direction H, the first reinforcing rib 23 and the second reinforcing rib 24 are cross-arranged, and together with the main frame 21, they form a triangular structure with two vertices facing each other. The two triangular structures form a stable support inside the connecting buckle, so that the entire buckle can maintain good shape stability when subjected to external loads. When the connecting buckle 20 is subjected to tension or shear force, the cross-reinforcing ribs can share the stress together, reduce stress concentration in a single part, and thus improve the overall rigidity. Therefore, the connecting buckle 20 can maintain good shape stability when subjected to a large load, and is not prone to deformation or breakage, so that the connecting buckle can more reliably connect the profile monomer 10, ensuring the structural safety of the entire profile assembly 100.

[0045] by Figure 2 As an example, the thickness direction of the main frame 21 is the first direction H, the length direction is the second direction L, and the width direction is the third direction. It can be understood that the identification of these directions (the first direction H, the second direction L, and the third direction W) are relative and may vary due to different designs or observation angles. This application is only for illustration.

[0046] In an optional solution of the present application, first holes b penetrating the main frame 21 are respectively provided on both sides of the main frame 21 along the first direction H; the provision of the first holes b reduces the material usage of the main frame in this direction, thereby reducing the overall weight.

[0047] Furthermore, the first reinforcing rib 23 and the second reinforcing rib 24 are respectively arranged in the two first holes b, that is, the space in the hole is utilized to embed the reinforcing rib therein, which not only maintains the compactness of the structure but also enhances the overall strength and rigidity of the connecting buckle. The close combination of the reinforcing rib and the main frame ensures the effective transmission and dispersion of the force, thereby improving the stability and durability of the connecting buckle when bearing external loads.

[0048] At the same time, the first reinforcing rib 23 and the second reinforcing rib 24 are respectively designed on the two sides of the main frame 21. This layout helps to fully reinforce the structure in three-dimensional space. No matter which direction the connecting buckle 20 is subjected to force in the first direction H, it can resist deformation and damage through the support of the reinforcing ribs.

[0049] In an optional manner, the cross section of the main frame 21 along the first direction H may be rectangular, and the first reinforcing rib 23 and the second reinforcing rib 24 are symmetrically arranged along the central axis of the main frame 21 along the first direction H. This allows the connecting buckle 20 to disperse stress more evenly when subjected to external loads, reducing the risk of deformation or damage caused by excessive local stress, and the main frame 21, the first reinforcing rib 23 and the second reinforcing rib 24 are easy to process.

[0050] As a preferred embodiment of the present application, the cross-section of the main frame 21 in the first direction H is in the shape of a parallelogram, including two first extension bodies 211 extending in the second direction L and parallel to each other, and two second extension bodies 212 extending in the third direction W and parallel to each other; the geometric shape of the parallelogram adopted by the main frame 21 helps to distribute stress more evenly when subjected to external loads, and this distribution method can reduce the stress concentration phenomenon and improve the overall strength and durability of the connecting buckle 20.

[0051] At least two hook portions 22 are provided on each first extension body 211 to form more connection points with the profile unit 10; this helps to disperse the stress at the connection points and reduce the risk of connection failure caused by excessive stress on a single point. At the same time, multiple connection points can also improve the stability of the connection and ensure that the connecting buckle is not easily detached or loosened when subjected to external forces.

[0052] In the embodiment of the present application, two hook portions 22 are provided on each first extension body 211, and the two hook portions 22 are respectively arranged at the ends of the first extension body 211; both ends of the first reinforcing rib 23 are respectively connected to the adjacent diagonal corners of the main frame 21; one end of the second reinforcing rib 24 is connected to the middle of one first extension body 211, and the other end is connected to the middle of the other first extension body 211.

[0053] Both ends of the first reinforcing rib 23 are respectively connected to the adjacent diagonal corners of the main frame 21. This connection method enables the first reinforcing rib 23 to form a support across the main frame 21, which helps to enhance the strength and stiffness of the main frame 21 in the diagonal direction and prevent twisting or deformation caused by external forces. In addition, the first reinforcing rib 23 can also balance and disperse forces from different directions to a certain extent and improve the overall stability of the connecting buckle.

[0054] One end of the second reinforcing rib 24 is connected to the middle of one first extension body 211, and the other end is connected to the middle of the other first extension body 211; this layout enables the second reinforcing rib 24 to provide additional support in the transverse direction (i.e., the third direction W) of the main frame 21, which helps to enhance the stiffness and stability of the main frame 21 in the transverse direction and prevent bending or deformation caused by external forces.

[0055] In the embodiment of the present application, the hook portion 22 includes a first section 221 and a second section 222. The first section 221 is connected to the first extension body 211, and the second section 222 is connected to the first section 221 and is arranged at an angle with the second section 222. The first section 221, the second section 222, and the first extension body 211 together form a hook groove c for hanging on the first through hole a.

[0056] It can be understood that the first section 221 is directly connected to the first extension body 211, and as the receiving part of the hook part 22, it is responsible for fixing the hook part 22 to the main frame 21. The first section 221 can be welded or integrally formed with the main frame 21 to ensure a firm connection with the first extension body 211 to withstand the force from the profile monomer 10. The second section 222 is connected to the first section 221 and is set at a certain angle to the first section 221. This angle design enables the second section 222 to form an "L" shape for hanging on the first through hole a on the profile monomer 10.

[0057] In the present application, the angle and length of the second section 222 can be adjusted according to the specific size and position of the first through hole a to ensure the stability and reliability of the hooking. The first section 221, the second section 222 and the first extension body 211 together form a hook groove c for hooking to the first through hole a. The shape and size of the hook groove c should accurately match the first through hole a to ensure that the connecting buckle 20 can be accurately hooked on the profile monomer 10.

[0058] In the present application, the hook grooves c on the two first extension bodies 211 are oriented in opposite directions, so that the connection buckle 20 can provide a stable constraint in two opposite directions when connected to the profile monomer 10. This directional constraint not only limits the movement of the connection buckle in a specific direction, but also ensures the stability and reliability of the connection. Even under a single external force, the connection buckle 20 can maintain its position unchanged to prevent it from falling off or loosening. The double hooking mechanism increases the stability of the connection and can effectively prevent the connection buckle from falling off or loosening.

[0059] The main frame 21 is provided with second holes d penetrating the main frame 21 on the two end faces along the second direction L. One of the second holes d is used as a lightweight hole and the other is used as a wire trough, providing an orderly channel for the arrangement of cables and other components outside the profile monomer 10. This helps to reduce the disorder of cables and improve the neatness and aesthetics of the overall structure. At the same time, the wire trough can also physically constrain the cables to prevent them from being damaged due to movement or vibration, thereby improving the reliability and safety of the system.

[0060] Each profile monomer 10 includes a profile body 11, and a plurality of first connecting portions 12 protruding relative to the surface of the profile body 11. The first connecting portions 12 and the surface of the profile body 11 together form a card slot e. The first through holes a are sequentially arranged at the corresponding card slots e on the profile body 11. The main frame 21 can be partially accommodated in the card slot e and is hung in the first through hole a through the hook portion 22.

[0061] The profile main body 11 serves as the main part of the profile unit 10, providing basic support and structural strength. It is the foundation for other components (such as the first connection part 12) and is also a core component of the entire profile unit 10.

[0062] The first connection part 12 is a part protruding from the surface of the profile main body 11, and together with the surface of the profile main body 11, it forms a card slot e. The design of the card slot e is to match the main body frame 21 of the connection buckle to achieve a stable connection. The protruding design of the first connection part 12 not only increases the contact area of the connection but also improves the strength and stability of the connection.

[0063] The card slot e formed by the profile main body 11 and the first connection part 12 should have a shape and size that match the main body frame 21 of the connection buckle to ensure that the connection buckle can be partially accommodated in the card slot e and achieve a stable hanging connection.

[0064] The first through hole a is provided on the profile main body 11 corresponding to the card slot e, that is, it is the hanging point for the hanging hook part 22 of the connection buckle. The position and size of the first through hole a should be precisely designed to ensure that the hanging hook part 22 can be accurately hung therein, thereby achieving a firm connection between the connection buckle and the profile unit 10.

[0065] In the embodiment of the present application, the first through hole a can be selected as a strip shape, and its width matches that of the hanging hook part 22; compared with circular or square through holes, the strip through hole provides a greater space tolerance. This means that during the insertion and hanging process of the hanging hook part 22, it can be adjusted and adapted within a certain range in the axial direction of the strip hole, making it easier to align with and hang on the first through hole a. This flexibility reduces the installation difficulty and improves the connection efficiency. It improves the connection stability, and since the width of the strip through hole matches that of the hanging hook part 22, when the hanging hook part 22 is fully hung into the through hole, the hanging hook part 22 can obtain stable support within the through hole, and this support function reduces the risk of connection loosening caused by vibration or external force, improving the connection stability.

[0066] In the present application, the depth of the card slot e is d1, and the width of the main body frame 21 along the third direction W is w1, where w1 = 2d1.

[0067] It is understandable that when the main frame 21 of the connecting buckle 20 is completely inserted into the card slot e of the profile unit 10, since d1 is equal to 2w1, both sides of the main frame 21 (in the third direction W) will be exactly surrounded by the two side walls of the card slot e (i.e., the first connecting portion 12). In this way, the main body part of the connecting buckle 20 is almost completely hidden inside the profile unit 10 visually, achieving the effect of hidden connection; the two side walls of the card slot e provide additional support and restraint for the main frame 21, not only improving the aesthetics of the overall structure, but also reducing the interference of the connecting buckle to the external environment and potential safety hazards. And because the main frame 21 is tightly surrounded by the card slot e, this design also enhances the stability of the connection.

[0068] On at least one adjacent surface of the surface of the profile main body 11 provided with the first connecting portion 12, a wire routing hole f and a plurality of second through holes g are provided. The wire routing hole f is provided at the end of the profile main body 11 for the entry and arrangement of cables. Because in the construction of the profile system, cables often need to be inserted from one end of the profile main body 11 and passed out from the other end to achieve electrical connection or data transmission. The plurality of second through holes g are provided on at least one adjacent surface of the profile main body 11, and the specific number and position of the second through holes g can be designed and adjusted according to actual needs, and they are usually used for installing other accessories or components, such as fixing plates, support frames, tarpaulins, etc.

[0069] Furthermore, those skilled in the art should understand that if all or part of the sub-modules involved in each product of the profile assembly 100 provided by the embodiments of the present application are combined, simply changed, or mutually transformed in ways such as detachable design; or some of its structures are designed in a split manner; as long as the combined components can form a structure with specific functions, using such a structure to replace the corresponding components of the present application also falls within the protection scope of the present application.

[0070] The above-described technical features can be combined arbitrarily. Although not all possible combinations of these technical features are described, any combination of these technical features should be considered to be covered by this specification as long as such a combination does not exist in contradiction.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still adjust the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these adjustments or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
