Description

Technical Field

[0001] The present application relates to the technical field of exhibition profiles, and in particular to a profile connector and a profile assembly. Background Art

[0002] Traditionally, whether it is a general profile or a profile designed specifically for exhibitions, its connection method often relies on the mechanical cooperation of slots and locks, angle brackets, or direct fastening with screws through holes. This traditional method has obvious disadvantages in actual operation: first, before installation, it is necessary to frequently use measuring tools to accurately position the profiles, because there is a lack of intuitive scale guidance for slot and angle bracket installation, and the distances between beams and longitudinal beams, and between structural parts and the ground and edges must be measured and confirmed one by one. This process is time-consuming and labor-intensive, which seriously restricts the efficiency of construction.

[0003] Secondly, since errors are inevitable during multiple measurements and positioning, these tiny errors may gradually accumulate during multiple assembly and connection processes, causing slight deformation of the overall structure, which not only affects the appearance, but may also pose a threat to structural stability and increase safety hazards.

[0004] Furthermore, the traditional connection method has high technical requirements for the assemblers. Once there is positioning deviation or improper installation, rework and adjustment are often required, which further increases the complexity and difficulty of assembly. This not only prolongs the construction period, but may also lead to increased costs and affect the smooth progress of the exhibition. Summary of the invention

[0034] like Figure 1 As shown, a profile connector 100 provided in an embodiment of the present application is used for connecting profile monomers 200 . The profile connector 100 includes a connector body 10 , a plurality of first connection structures 20 , and a plurality of second connection structures 30 .

[0035] Based on the general inventive concept of the present application, the connector body 10 includes a first side A and a second side B that are adjacent and perpendicular to each other; a plurality of first connecting structures 20 protrude from the first side A; a plurality of second connecting structures 30 protrude from the second side B; and two profile monomers 200 can be vertically connected by being respectively plugged into the first connecting structures 20 and the second connecting structures 30.

[0036] It can be understood that the connector body 10 can adapt to the connection requirements in at least two directions at the same time, that is, the first side A is used to connect with a profile monomer 200, and the second side B is connected with another profile monomer 200 in a vertical direction. The profile monomer 200 can be installed vertically with simple assembly, which not only simplifies the assembly process, but also enhances the stability and structural strength of the connection. The two profile monomers 200 are connected vertically by being plugged into the first connection structure 20 and the second connection structure 30 respectively. This plug-in connection is not only easy to operate, but also can quickly complete the connection, thereby improving construction efficiency.

[0037] In the specific scheme of the present application, the first connecting structure 20 includes a first connecting part 21 and a second connecting part 22, and the second connecting structure 30 includes a third connecting part 23 and a fourth connecting part 24; the first connecting part 21 and the second connecting part 22 are respectively arranged at the edges of the first side surface A; the third connecting part 23 and the fourth connecting part 24 are respectively arranged at the edges of the second side surface A.

[0038] The first connection part 21 and the second connection part 22 together constitute the first connection structure 20, and are respectively arranged at the edge of the first side A of the connector body 10. This layout enables the first connection structure 20 to fit tightly and be fixed to the corresponding part of the profile monomer 200, ensuring the stability of the connection; the third connection part 23 and the fourth connection part 24 are similar, and these two parts constitute the second connection structure 30, and are arranged at the edge of the second side B of the connector body 10. The above arrangement can take into account the convenience of subsequent installation and maintenance, that is, by setting the connection part at a specific position (such as the side edge), sufficient space can be reserved on the connector body 10 for subsequent opening, wiring or other installation requirements. At the same time, the above-mentioned connection part is arranged at the edge of the profile connector 100, which can form a frame reinforcement structure, which can effectively disperse and resist external loads, and improve the rigidity and strength of the connector and the entire profile structure.

[0039] The profile connector 100 further includes a corner mounting block 40, which is disposed at the connection between the first side surface A and the second side surface B; the corner mounting block 40 includes: a first extension portion 41 perpendicular to the first side surface A, a second extension portion 42 perpendicular to the second side surface B, and an inclined mounting portion 43 inclined at an angle of 45° to the first extension portion 41 and the second extension portion 42. The first extension portion 41 and the second extension portion 42 are respectively concave relative to the first side surface A and the second side surface B, and the first connection portion 21 and the third connection portion 23 are respectively connected to the two opposite sides of the inclined mounting portion 43.

[0040] It can be understood that the first extension portion 41 is perpendicular to the first side A and is concave relative to the first side A. This design can reduce interference with the profile monomer 200 or other components, reduce the volume of the connector, and avoid the profile connector 100 from forming an abrupt structural part, which affects the aesthetics of the profile. Similarly, the second extension portion 42 is perpendicular to the second side B and is concave relative to the second side B. Similar to the first extension portion 41, the second extension portion 42 also provides support for the corner mounting block 40 in the vertical direction (relative to the first side A) and reduces potential interference problems. The inclined mounting portion 43 is inclined at a 45° angle to the first extension portion 41 and the second extension portion 42. This design enables the inclined mounting portion 43 to serve as a transition and connecting bridge between two vertical connecting portions while maintaining the compactness and aesthetics of the structure. The first connecting portion 21 and the third connecting portion 23 are respectively connected to the two opposite sides of the inclined mounting portion 43. This replaces the traditional limitation that the connecting portion must be respectively arranged on two vertical sides, so that the profile monomer 200 can also achieve seamless and stable connection at the corner.

[0041] In the embodiment of the present application, the connector body 10 further includes an end face C, and the corner mounting block 40 partially protrudes from the end face C along the extension direction of the connector body 10. That is, the corner mounting block 40 can be plugged into the profile monomer 200 to form a match, thereby constructing an exposed groove structure to provide plug-in convenience, which can be described later for details.

[0042] The profile connector 100 includes a cloth-binding slot structure 50 , which is disposed at the edges of two side surfaces opposite to the first side surface A and the second side surface B, and protrudes from the end surface C along the extension direction.

[0043] The cloth-slot structure 50 is disposed on two specific sides of the profile connector 100, which are opposite to the "first side A" and the "second side B". When the profile unit 200 is connected to the first side A and the second side B to form a frame, the cloth-slot structure 50 is located outside the formed frame to form a slot; the slot is designed to achieve installation of the cloth across the frame. In other words, the cloth can be stretched and fixed in the slot to achieve tight installation across the frame.

[0044] Furthermore, the cloth-binding groove structure 50 includes a first groove wall 51 and a second groove wall 52, and the first groove wall 51, the second groove wall 52 and the end face C together enclose a first groove body E; wherein the second connecting portion 22 is arranged between the first groove wall 51 and the second groove wall 52, and the fourth connecting portion 24 is arranged between the first groove wall 51 and the second groove wall 52.

[0045] As before, the cloth-stretching slot structure 50 includes a first slot wall 51 and a second slot wall 52, which together with the end face C enclose a first slot body E. When the profile unit 200 is connected to the profile connector 100, they together form a frame, in which the cloth-stretching slot structure 50 (including its first slot wall 51 and second slot wall 52) of the profile connector 100 cooperates with the corresponding part of the profile unit 200 (possibly through the second connecting part 22 and the fourth connecting part 24 or other connecting mechanisms). This cooperation forms a continuous and smooth effect at the outer edge of the entire frame, which can form a pluggable second slot body at the outer edge of the entire frame (see below), avoid structural faults, enhance the structural stability of the frame, make the entire frame more visually unified and coordinated, avoid the abrupt feeling caused by loose connection or misalignment of components, and thus improve its aesthetics.

[0046] In the embodiment of the present application, the interior of the connector body 10 is a hollow cavity, and a wiring through hole D connected to the hollow cavity is provided at the end face C; thereby allowing cables, wires, or embedded optical strips or other similar slender objects to pass through the interior of the hollow cavity without destroying the structure of the connector or affecting its appearance. For example, when constructing a framework that requires electrical connection or signal transmission, the cables can be neatly arranged in the hollow cavity through the wiring through hole D, and then connected from the appropriate position of the connector to connect to other devices or components. This not only ensures the structural integrity of the frame, but also realizes the reliable transmission of electricity or signals. In addition, it can also reduce the weight of the connector body 10, save materials and achieve a lightweight setting.

[0047] The connector body 10 includes a reinforcing partition 11, which is arranged in the central control cavity and connected to the corner mounting block 40 at one end and the diagonal of the corner mounting block 40 at the other end. By setting the reinforcing partition 11, the originally continuous hollow cavity is divided into two independent spaces. This separation not only helps to optimize the utilization of the internal space, but also may have a positive impact on the performance of the connector. For example, the separated spaces can be used to accommodate different types of cables or pipes, respectively, so as to avoid mutual interference and facilitate maintenance and installation; at the same time, the reinforcing partition 11 is connected to the corner mounting block 40 and its diagonal, which forms two stable triangular support systems to increase its When the connector is subjected to external force, the reinforcing partition 11 can transmit the external force to a wider area like the support beam of a bridge, thereby reducing the possibility of local deformation. In addition, the reinforcing partition 11 can also limit the expansion or contraction of the hollow cavity when subjected to pressure or tension, further enhancing the anti-deformation ability of the connector.

[0048] Furthermore, in an embodiment of the present application, a first wiring hole F and a first-level bolt connection hole G are provided on at least one of the first side surface A and the second side surface B; the first wiring hole F is respectively located at the two ends of the connector body 10. This layout allows cables to enter or pass through from both ends of the connector, which is convenient for flexible cable arrangement during construction. A plurality of first bolt connection holes G are arranged between the wiring holes F and are arranged at equal intervals. A plurality of first bolt connection holes G are arranged between the wiring holes F, so that when connecting other components on the frame, the process is more standardized and easy to operate, without the need for additional holes. The number and position of the bolt connection holes can be adjusted according to actual needs to meet the connection requirements in different application scenarios.

[0049] The first bolt connection holes G are designed to be evenly spaced on the connector body 10. This feature not only ensures the uniformity and stability of the connection between the connector and the profile monomer or other components, but also can serve as a reference for position. An exemplary application scenario is: During the construction of a large structure or system, it is often necessary to install connectors and profile monomers according to a specific spacing or layout. The evenly spaced setting of the first bolt connection holes G provides an intuitive reference, allowing installers to easily install according to the predetermined spacing without the need for additional measuring tools, thereby improving installation efficiency and accuracy.

[0050] In summary, the profile connector 100 provided in the embodiment of the present application ensures that the profile monomers 200 can form a tightly fitting right-angle corner when connected through the precisely designed first connection structure 20 and second connection structure 30, achieving a high degree of accuracy both visually and structurally. The design of the profile connector 100 follows the principle of simplicity and clarity, allowing operators to quickly operate without complex training, effectively shortening the time period for exhibition construction.

[0051] Furthermore, those skilled in the art should understand that if all or part of the sub-modules involved in the profile connector 100 products provided in the embodiments of the present application are combined and replaced by fusion, simple change, mutual conversion, etc., such as a detachable design; or some of its structures are designed as a split type; all the combined components can form a structure with specific functions, and using such a structure to replace the corresponding components of the present application also falls within the scope of protection of the present application.

[0052] like Figure 2 As shown, the second aspect of the present application further provides a profile assembly 1000 , comprising the profile connector 100 as described above and a plurality of profile monomers 200 .

[0053] The single profile body 200 includes a profile body 201, and at least two plug-in parts 202 protruding from the profile body 201 are provided on each side of the two side edges of the profile body 201. The plug-in parts 202 are not only used for plug-in connection with the first connection structure 20 or the second connection structure 30 of the profile connector 100, but also form a second groove H together with the profile body 201. This design makes the connection process simpler and more direct, while improving the stability of the connection.

[0054] When the profile unit 200 needs to be connected to the profile connector 100, the second groove H of the profile unit 200 only needs to be aligned with the first connection structure 20 or the second connection structure 30 of the connector and pushed in forcefully to achieve connection. This plug-in connection method is not only easy to operate, but also has a firm and reliable connection.

[0055] Furthermore, when the profile monomer 200 is inserted into the first connection structure 20 or the second connection structure 30 of the profile connector 100, the top (or bottom, depending on the connection direction) of the profile monomer 200 should remain flush with the corresponding surface of the connector body 10. This flush state ensures the uniformity of the entire profile assembly 1000 in the vertical direction and avoids unevenness. At the same time, during the connection process, the plug-in portion 202 on one side of the profile monomer 200 will dock and align with the first extension portion 41 (or the second extension portion 42) and the inclined mounting portion 43 of the corner mounting block. This flush state not only ensures the aesthetics of the structure, but also enhances the stability of the connection. The plug-in portion 202 on the other side of the profile monomer 200 will dock and align with the first slot wall 51 and the second slot wall 52 of the cloth clamping slot structure. This design enables the cloth-stretching slot to be closely attached to the profile unit 200, providing a more stable and reliable cloth-stretching fixing effect; through the above-mentioned flush docking, a groove protruding from the surface of the profile unit 200 and the connector body 10 will be formed between the profile unit 200, the corner mounting block 40, the cloth-stretching slot structure 50 and the connector body 10. The groove can not only provide more functions and uses for the profile assembly 1000 (such as fixing exhibition boards, cloth stretching, display light boxes, etc.), but also increase the layering and three-dimensional sense of the overall structure. At the same time, the appearance of the entire exhibition frame will show a high degree of consistency, and form a closer contact and support, thereby reducing stress concentration and potential structural weaknesses caused by gaps or misalignments.

[0056] In a further solution of the present application, a second wiring hole I and a second bolt connection hole J are provided on the profile body 201; the second wiring hole I is respectively located at the two ends of the profile body 201; a plurality of second bolt connection holes J are arranged between the second wiring holes I and are arranged at equal intervals.

[0057] As above, the second wiring holes I are respectively located at the two ends of the profile body 201. It is convenient to arrange and hide the wires, data lines or other pipelines between the profile monomers, so that the internal lines of the exhibition frame are neat and orderly, and the safety and aesthetics of the exhibition venue are also improved. A plurality of second bolt connection holes J are arranged between the second wiring holes I and are evenly spaced. Such a design not only ensures the uniformity and stability of the connection, but also facilitates the bolt connection at different positions as needed, and also serves as a position reference.

[0058] The various technical features described above can be combined arbitrarily. Although all possible combinations of these technical features are not described, any combination of these technical features should be considered to be covered by this specification as long as there is no contradiction in such combination.

[0059] 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 it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still adjust the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, 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.
