Description

Technical Field

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

[0002] In the booming development of the Chinese exhibition industry, a remarkable phenomenon is the rapid growth in the number of exhibitions, which has directly led to a shortening of the exhibition preparation cycle, a relatively tight actual exhibition time, and a reduction in costs. In the practical application of the aluminum profile building system, profile fasteners, as key components for connecting profile frames, their performance and design directly affect the stability and aesthetics of the entire building system. Currently, common profile fasteners on the market mostly adopt L-shaped mounting blocks or wedge block structures (such as Figure 1 ), and are locked by cooperating with bolts. Although this traditional connection method realizes the connection of profiles to a certain extent, there are still many deficiencies:

[0003] 1. The traditional method requires precise measurement, alignment, and fastening operations, which have high requirements for the skills and experience of installers, increasing the installation difficulty and time cost; and disassembly is also relatively difficult, and the efficiency of reuse is not high.

[0004] 2. Since fasteners such as bolts and mounting blocks need to occupy a certain space and often cannot be completely hidden inside the profiles, it is inconvenient to route wires between the frames, affecting the overall aesthetics and neatness. Especially in exhibition design, exposed fasteners may damage the integrity and visual effect of the design.

[0005] Therefore, this application is proposed. Summary of the Invention

[0006] The purpose of this application is to address the problems in the prior art such as the cumbersome connection process of profile fasteners in the aluminum profile building system, the difficulty in achieving hidden connection, and the relatively high maintenance cost. The aim is to design a new type of profile assembly to reduce the requirements for the skills and experience of installers, make the connection process more simple and fast, improve the installation efficiency, and reduce the time cost. At the same time, it can also ensure that when connecting profile frames, it can be completely or mostly hidden inside the profiles, reducing the exposed part, thereby achieving hidden connection. This not only improves the overall aesthetics of the exhibition but also avoids the problem of inconvenient wire routing.

[0007] This application provides a profile unit, including a profile body having a first cavity, and two first connection parts protruding from the outer wall of the profile body. The adjacent first connection parts and the profile body form a first groove, and the profile body is provided with a first jack in the corresponding first groove; a profile fastener, including a fastener body and a pin part provided on the fastener body and matching the first jack; wherein, the fastener body can be at least partially accommodated in the first groove and is inserted into the first jack through the pin part.

[0008] In a further embodiment of the present application, the latch portions are provided in pairs, and the two latch portions of the pair are respectively provided on both sides of the fastener body and are symmetrically arranged with respect to the fastener body.

[0009] In a further embodiment of the present application, the latch portion includes: a latch housing with a second cavity inside; a wire routing hole provided on at least one side of the latch housing and penetrating the latch housing; wherein, when the latch portion is inserted into the first jack, the wire routing hole communicates the second cavity and the first cavity.

[0010] In a further embodiment of the present application, the wire routing hole is provided on one side of the latch housing, and the latch portion further includes an avoidance notch provided on the side opposite to the wire routing hole, wherein the avoidance notch is inclined with respect to the end face of the latch housing.

[0011] In a further embodiment of the present application, the length of the latch portion matches the first cavity, so that when the latch portion is inserted into the first jack, the end face of the latch housing and the inner wall of the bottom of the first cavity abut against each other.

[0012] In a further embodiment of the present application, the fastener body includes a fastener housing, and the latch portion is provided on the outer wall of the fastener housing; wherein, the fastener housing has a third cavity inside, and the third cavity has openings at both end faces of the fastener housing.

[0013] In a further embodiment of the present application, at least one connection hole penetrating the fastener housing is provided on two surfaces of the fastener housing and the latch portion on the same side, and the connection hole is used to screw the profile fastener onto the profile unit.

[0014] In a further embodiment of the present application, the depth of the first groove is d1, and the height of the fastener body in the height direction H is h1, where d1 = 2h1.

[0015] In a further embodiment of the present application, the profile unit further includes two second connection portions respectively provided at the edges of the profile unit, and the first connection portion is provided between the two second connection portions; wherein, the adjacent first connection portion, second connection portion and profile unit form a second groove.

[0016] In a further embodiment of the present application, an inclined cut surface is provided at each end of each profile unit; a plurality of profile units are connected to each other through the inclined cut surfaces to form a profile frame, and the profile frames are connected to each other through profile fasteners; wherein, the first jacks are all provided at the two ends of the profile unit.

[0017] In summary, a profile assembly provided by the present application at least has the following beneficial effects:

[0018] 1) The connection process is made very intuitive and simple by inserting the profile fasteners. The installer only needs to arrange the profile units in a predetermined manner to form a frame, and then quickly insert the pin part of the fastener into the first jack to complete the mounting or connection of the frame. This plug-and-play design can reduce the installation time and labor costs. Since the connection process is simple and fast, the entire construction process can be carried out quickly, especially suitable for some application scenarios that require rapid construction of temporary exhibitions, display racks, work platforms, etc.

[0019] 2) It can reduce the error rate during the installation process. Since each component has a clear positioning and connection method, it is very difficult for the installer to place the components in the wrong position or connect them incorrectly. This further improves the accuracy and efficiency of the construction.

[0020] 3) The fastener body in this application can be partially accommodated in the first groove, enabling a hidden connection, so that the fastener body is not exposed outside the profile assembly. By hiding the fastener, the entire structure can look neater and more professional, thus maintaining the overall aesthetics. And the first groove can provide additional connections, making the fastener body have stronger stability and load-bearing capacity during connection; it ensures both aesthetics and the reliability of the connection.

[0021] 4) The first cavity included in the profile unit can be used for wire routing. By arranging the wires in the first cavity of the profile unit, the effective use of space is realized, avoiding the problems of exposed and messy wires in the traditional wiring method.

[0022] Other features and advantages of the embodiments of this application will be described in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0039] As Figures 2 to 5 shown, an extruded profile assembly 100 provided by an embodiment of this application includes several extruded profile monomers 10 and extruded profile fasteners 20; where "several" indicates that there are at least two extruded profile monomers 10.

[0040] The extruded profile monomer 10 is usually designed into a long and strip-shaped extended structure, and this shape enables it to be conveniently arranged, stacked, or spliced to meet the requirements of various sizes and shapes.

[0041] In this embodiment, the cross-sectional shape of the extruded profile monomer 10 can be diverse, such as rectangular, I-shaped, etc., and can be specifically configured according to the application environment to adapt to different mechanical properties and installation requirements.

[0042] The extruded profile fastener 20 is used to connect the extruded profile monomers 10, and it can connect between the extruded profile monomers 10 or connect the extruded profile monomer 10 and other structures.

[0043] It is specifically pointed out in this embodiment that the extruded profile fastener 20 is connected at the side part of the extruded profile monomer 10, rather than at the end.

[0044] Based on the general inventive concept of the embodiments of the present utility model, each profile unit 10 includes a profile body 11 having a first cavity a1, and two first connecting portions 12 protruding from the outer wall of the profile body 11. The adjacent first connecting portions 12 and the profile body 11 form a first groove b1, and the profile body 11 is provided with a first insertion hole c in the corresponding first groove b1. Further, the profile fastener 20 includes a fastener body 21 and a pin portion 22 provided on the fastener body 21 and matching with the first insertion hole c. At the same time, the fastener body 21 can be partially accommodated in the first groove b1, and is inserted into the first insertion hole c through the pin portion 22.

[0045] It can be understood that the above-mentioned "profile body 11" is the main part of the profile unit 10. Specifically, the profile body 11 is a hollow structure with a first cavity a1 inside. The first cavity a1 can be used to accommodate items such as wires, pipes, light strips, and decorative strips to achieve concealed wiring, that is, to improve the practicality of the profile while taking into account the lightweight design.

[0046] In the embodiments of the present utility model, the two first connecting portions 12 protruding from the outer wall of the profile body 11 enhance the structural strength of the edge of the profile, preventing deformation or damage caused by external forces, and also providing a necessary positioning structure for connection. In this application, the space formed between the adjacent first connecting portions 12 and the profile body 11 is the first groove b1. A first insertion hole c is provided at the position of the profile body 11 corresponding to the first groove b1 (which can be understood as the bottom of the first groove b1). The first insertion hole c is designed to match the pin portion 22 of the profile fastener 20, so as to achieve the fastening connection between the profile units. Similarly, the fastener body 21 is the main part of the profile fastener 20, and the first groove b1 and the fastener body 21 also match each other.

[0047] Based on the above structure, the installer only needs to insert the pin portion 22 of the profile fastener 20 into the first insertion hole c on the profile unit 10, and at the same time, the fastener body 21 is clamped into the first groove b1, then the preliminary installation of the profile fastener 20 and the profile unit 10 can be realized. It is simple and convenient, and can improve the building speed of the profile unit 10.

[0048] As Figure 6 shown, in an optional solution of the present application, the pin portion 22 can be only provided on one side of the fastener body 21. After connecting the pin portion 22 on one side to the profile unit 10, the other side of the profile unit 10 away from the pin portion 22 is connected to an external mounting surface (such as a wall surface) to achieve the quick mounting of the profile unit 10. Among them, the forms of the profile unit 10 and the external mounting surface are not limited, and can be at least one of bonding, screwing, and clamping.

[0049] As Figure 7As shown, in another alternative embodiment of the present application, the pin portions 22 are disposed on both sides of the fastener body 21 and are symmetrically arranged with respect to the fastener body 21 to adapt to the connection between two profile monomers 10. Specifically, the adjacent first grooves b1 of the two profile monomers 10 are aligned so that their first insertion holes c are opposite. The pin portions 22 on both sides of the profile fastener 20 are respectively aligned and inserted into the first insertion holes c of the two profile monomers 10; after the pin portions 22 are completely inserted, due to their tight fit with the first insertion holes c, the two profile monomers 10 are firmly connected together.

[0050] In summary, for the profile assembly 100 provided by the embodiments of the present invention, the connection process becomes very intuitive and simple through the insertion of the profile fastener 20. The installer only needs to arrange the profile monomers 10 in a predetermined manner to form a frame, and then quickly insert the pin portions 22 of the profile fastener 20 into the first insertion holes c to complete the mounting or mutual connection of the frame. This plug-and-play design can reduce the installation time and labor costs. Since the connection process is simple and fast, the entire construction process can be carried out quickly. At the same time, it can reduce the error rate during the installation process. Because each component has a clear positioning and connection method, it is very difficult for the installer to place the components in the wrong position or connect them incorrectly, which further improves the accuracy and efficiency of the construction.

[0051] Particularly, the fastener body 21 in the present application can be partially accommodated in the first groove b1, which can achieve a hidden connection, so that the fastener body 21 is not exposed outside the profile assembly 100. By hiding the fastener, the entire structure can look cleaner and more professional, thus maintaining the overall aesthetics. And the first groove b1 can provide additional connection, making the fastener body 21 have stronger stability and load-bearing capacity during connection, thus ensuring both aesthetics and the reliability of the connection.

[0052] In an embodiment of the present application, the pin portion 22 includes a pin housing 221 and a wire routing hole 222. The interior of the pin housing 221 is a second cavity a2; the wire routing hole 222 is disposed on at least one side of the pin housing 221 and penetrates the pin housing 221; wherein, when the pin portion 22 is inserted into the first insertion hole c, the wire routing hole 222 communicates the second cavity a2 and the first cavity a1.

[0053] The pin housing 221 can be annular or rectangular, depending on the actual application requirements; the wire routing hole 222 is disposed on at least one side of the pin housing 221 and penetrates the pin housing 221 on this side (it can be understood that the wire routing hole 222 is a through hole).

[0054] Specifically, align the plug housing 221 of the plug part 22 with the first socket c on the profile monomer 10 and insert it with force. During the insertion process, the plug housing 221 will gradually enter the first socket c until it is fully inserted and fixed in place. At this time, a stable connection is formed between the plug part 22 and the profile monomer 10. When the plug part 22 is plugged into the first socket c, the wiring hole 222 connects the second cavity a2 with the first cavity a1 inside the profile monomer 10. In this way, the wiring hole 222 allows the passage of the wiring harness, and the wiring hole 222 also provides a clear channel for the wiring harness or pipeline of the first cavity a1, so that the wiring harness can be arranged according to a predetermined path. When the wiring harness passes through the wiring hole 222, its position and direction are relatively fixed, reducing the possibility of the wiring harness moving or entangled at will inside the profile assembly. This positioning effect helps to keep the wiring harness neat and orderly, and facilitates subsequent management and maintenance.

[0055] The wiring hole 222 is arranged at one side of the latch housing 221 . The latch portion 22 further includes an avoidance notch 223 . The avoidance notch 223 is arranged at a side opposite to the wiring hole 222 . The avoidance notch 223 is arranged obliquely relative to the end surface of the latch housing 221 .

[0056] The avoidance notch 223 is arranged on a side opposite to the wiring hole 222 and is arranged obliquely relative to the end surface of the plug housing 221. This oblique design is usually to provide sufficient space during the plugging process to avoid interference and collision.

[0057] The avoidance notch 223 is to ensure that the plug part 22 can smoothly avoid possible obstacles or interference points when inserted into the first insertion hole c of the profile unit 10. For example, when the plug part 22 completely enters the first insertion hole c, if there is no avoidance notch 223, it may directly and tightly close the bottom of the first cavity a1, making it impossible for the wire harness or pipe to pass through. The design of the avoidance notch 223 can ensure that there is still a certain gap between the plug part 22 and the inner wall of the bottom of the first cavity a1, thereby meeting the requirement for the wire harness to pass through.

[0058] In addition, at the place where two profile monomers 10 are vertically connected, the avoidance notches 223 can prevent the multiple profile fasteners 20 at the vertical corners from interfering with each other. These avoidance notches 223 are connected to each other at the corners, and cooperate with the wiring holes 222 to form a continuous, barrier-free channel, providing a precise wiring path for internal facilities such as wiring harnesses. In this way, not only the compactness and aesthetics of the overall structure are improved, but also the structural strength at the connection can be improved.

[0059] Furthermore, the length of the plug portion 22 matches the first cavity a1, so that when the plug portion 22 is inserted into the first insertion hole c, the end surface of the plug housing 221 and the inner wall of the bottom of the first cavity a1 abut against each other.

[0060] The tight fit between the plug portion 22 and the first cavity a1 effectively restricts the freedom of the plug portion 22 in the plugging direction, thus achieving stable fixation of the connecting component or structure. Through the direct contact and abutment between the plug portion 22 and the bottom of the first cavity a1, the force transmission at the connection point is more direct and effective, thereby enhancing the strength and stability of the entire connection structure and preventing the plug portion 22 from wobbling.

[0061] The fastener body 21 includes a fastener housing 211, and the plug portion 22 is provided on the outer wall of the fastener housing 211; wherein, the interior of the fastener housing 211 is a third cavity a3, and the third cavity a3 has openings d at both end faces of the fastener housing 211; thus, wires, light strips, pipes, etc. can also be arranged inside the third cavity a3.

[0062] It can be understood that the fastener body 21 not only functions as a connecting component, but also integrates the external wiring function of the profile unit 10. Specifically, a third cavity a3 is designed inside the fastener housing 211, and the cavity is provided with openings d at both end faces of the fastener housing 211. Such a design makes the third cavity a3 a through channel that can accommodate and protect components such as wires, light strips, and pipes, and external wiring or routing can be carried out through the third cavity a3, thus avoiding the chaos and safety hazards that may be brought about by directly arranging these components outside the profile unit 10.

[0063] On two sides of the fastener housing 211 and the plug portion 22 on the same side, at least one connection hole 212 penetrating the fastener housing 211 is provided, and the connection hole 212 is used to screw the profile fastener 20 onto the profile unit 10. The main function of the connection hole 212 is to serve as a screw connection point, allowing bolts, screws or other fasteners to firmly fix the profile fastener 20 on the profile unit 10 and / or the external mounting surface. By using the tight fit between the thread of the bolt or screw and the connection hole 212, high-strength connection of the profile fastener 20 is achieved, so as to be able to withstand large tensile and shear forces and ensure the stability and reliability of the connection.

[0064] The groove depth of the first groove body b1 is d1, and the height of the fastener body 21 is h1, where d1 = 2h1. When two profile units 10 are connected by the profile fastener 20, the fastener body 21 can be exactly and completely embedded into the first groove body b1 of each of the two profile units without any extra exposed part; this makes the appearance of the connection part neat without any messy protrusions, improving the overall aesthetics. At the same time, this tight fit helps to enhance the stability of the connection and reduce the risk of loosening or falling off of the profile unit 10 caused by vibration or external forces.

[0065] The profile unit 10 further includes two second connecting parts 13, which are respectively arranged at the edges of the profile unit 10, and the first connecting part 12 is arranged between the two second connecting parts 13; wherein, the adjacent first connecting part 12, second connecting part 13 and profile unit 10 form a second groove body b2. The profile unit 10 of the second groove body b2 provides an additional connection point. Exemplarily, it can be used as a structure for installing decorative or functional elements such as Kabu lanterns, curtain screens, LED display screens, etc. It is fixed in the second groove body b2 by a specific fixing method (such as screws, snap connections, etc.), so as to realize a firm connection with the profile unit 10. In addition, the second groove body b2 also enhances the structural strength and stability of the profile unit 10. It helps to disperse and resist forces and stresses from different directions, thereby improving the load-bearing capacity of the entire structure.

[0066] In an alternative solution of the embodiment of the present application, bevel cuts e are provided at the ends of each profile unit 10; a plurality of profile units 10 are connected to each other through the bevel cuts e to form a profile frame; wherein, the first jacks c are all arranged at the two ends of the profile unit 10.

[0067] First, the provision of the bevel cuts e enables a plurality of profile units 10 to be connected to each other in a specific manner, so as to construct the required profile frame, and the profile frame can be rectangular or square. Specifically, when two or more profile units need to be connected, their bevel cuts e will come into contact and fit tightly with each other. This connection method is not only simple and fast, but also can ensure the firmness and accuracy of the connection. Secondly, the design of the bevel cuts e also takes into account the force transmission and dispersion between the profile units. When the profile frame is subjected to external forces, the bevel cuts e can guide the forces to be transmitted along specific directions, thereby avoiding stress concentration and local damage. At the same time, the contact area of the bevel cuts e is relatively large, which helps to disperse and resist forces and stresses from different directions, and improves the load-bearing capacity and stability of the entire profile frame.

[0068] The above-provided profile fastener 20 can be used for the connection of the profile frame. The design of the profile fastener 20 allows the profile frame to be applicable to a variety of connection scenarios. Whether it is the connection of external mounting points, the stacked connection of two profile frames, or the side-by-side connection, it can all be realized through the same profile fastener 20, making the installation process simple and fast, and having high flexibility. Moreover, it can adopt a standardized design, which also enables installers to easily use the same fastener in different scenarios, without having to customize specific fasteners for each connection scenario, having replaceability, and also avoiding installers from carrying multiple different components, thus improving the installation efficiency. In addition, the profile fastener 20 has a simple structure and strong compatibility, and can be manufactured by various methods such as 3D printing and machining, which can reduce the manufacturing cost.

[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 component 100 provided in the embodiments of the present application are combined, simply changed, or mutually transformed in ways such as fusion, for example, a detachable design; or part of its structure is designed in a split form; as long as the combined components can form a structure with specific functions, replacing the corresponding components in the present application with such a structure also falls within the protection scope of the present application.

[0070] The technical features described above 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, rather than 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 described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these adjustments or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
