Technical Field

[0001] This application relates to the field of connector technology, and more particularly to profile assemblies and their built-in connecting components. Background Technology

[0002] Profiles are solid straight bars made of iron or steel, or other materials with a certain strength and toughness, shaped and processed to have a specific cross-sectional shape and size. Some profiles also have mounting grooves. During use, two profiles need to be connected and fixed. This is usually done using connectors, whose two ends are fitted against the side surfaces of the two profiles, and then bolts are used to connect them. Since the connectors are installed on the surfaces of the two profiles, the bolt heads are exposed, reducing the overall aesthetic appeal. Utility Model Content

[0003] To solve the above-mentioned technical problems and achieve at least one advantage of this application, this application provides a built-in connecting member, in which two profiles are connected by at least one of the built-in connecting members. Each profile forms at least one mounting groove extending along its own length direction, and each mounting groove has an opening communicating with it. Each profile forms an abutting end face, and the abutting end faces formed by the two profiles abut against each other. The at least one mounting groove formed by the two profiles abuts and communicates with each other. The built-in connecting member includes a built-in connector, and each built-in connector has two connected connecting portions, wherein one connecting portion is inserted into the mounting groove formed by one profile, and the other connecting portion is inserted into the mounting groove formed by the other profile.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 4 A preferred embodiment of the profile assembly according to this application will be described in detail below. The profile assembly includes at least two profiles 10 and at least one built-in connecting member 20.

[0023] Each of the built-in connecting members 20 is connected to two of the profiles 10, such that every two profiles 10 are connected together by at least one of the built-in connecting members 20. To facilitate understanding of the technical solution of this application by those skilled in the art, the following embodiments are illustrated by taking the connection of two profiles 10 by at least one of the built-in connecting members 20 as an example, but this does not mean that the profile assembly is limited to setting two profiles 10.

[0024] Specifically, each profile 10 forms at least one mounting groove 101 extending along its own length, and each mounting groove 101 has an opening 102 communicating with it. Each profile 10 forms an abutment end face 103, the abutment end faces 103 formed by two profiles 10 abut against each other, and the at least one mounting groove 101 formed by two profiles 10 respectively connects with each other.

[0025] The built-in connecting component 20 includes a built-in connector 21 and two assembly fittings 22. Each built-in connector 21 is inserted between two mating and communicating assembly slots 101. The two sets of assembly fittings 22 are respectively installed between two profiles 10 and one built-in connector 21, so that the built-in connector 21 is connected to the two profiles 10 through the assembly fittings 22, and thus the two profiles 10 are connected through the built-in connecting component 20. Since the built-in connector 21 is inserted into the assembly slot 101 formed by the profile 10, the built-in connector 21 is hidden, making the overall appearance of the profile assembly cleaner and more aesthetically pleasing.

[0026] Specifically, each of the built-in connectors 21 has two connected connecting portions 211, wherein one connecting portion 211 is inserted into the assembly groove 101 formed by one of the profiles 10, and the other connecting portion 211 is inserted into the assembly groove 101 formed by another profile 10.

[0027] After one connecting portion 211 of the built-in connector 21 is kept opposite to one end face of the profile 10 and aligned with the corresponding port of the mounting groove 101, the built-in connector 21 moves toward the direction of inserting the connecting portion 211 into the corresponding mounting groove 101, so that the built-in connector 21 is assembled with the profile 10; then another profile 10 is aligned with the built-in connector 21 with the port of its own formed mounting groove 101 aligned with another connecting portion 211 of the built-in connector 21, and then the corresponding profile 10 moves close to the built-in connector 21, so that the built-in connector 21 is assembled with the other profile 10.

[0028] In one embodiment, two profiles 10 are arranged side by side and abut against each other; at this time, the built-in connector 21 is in a straight line shape, and the axes of the two connecting portions 211 of the built-in connector 21 coincide. According to actual needs, a corresponding number of profiles 10 are connected by the built-in connector 20 so that the profile assembly reaches a preset length.

[0029] In one example, the abutting end face 103 formed by each of the profiles 10 is perpendicular to its own length direction.

[0030] In another embodiment, the abutting end face 103 formed by each of the profiles 10 intersects its own length direction at a preset angle, and the two profiles 10 maintain the abutting end faces 103 abutting in an attitude in which their respective length directions intersect at a predetermined angle; at this time, the included angle between the axes of the two connecting portions 211 of the built-in connector 21 is the same as the included angle between the two profiles 10.

[0031] In one example, the two profiles 10 abut perpendicularly, and the angle between the axes of the two connecting portions 211 of the built-in connector 21 is ninety degrees. Preferably, the angle between the abutting end face 103 formed by each profile 10 and its own length direction is forty-five degrees.

[0032] It is worth mentioning that both connecting portions 211 form through holes 21101, and both profiles 10 form threaded holes 104. The threaded holes 104 formed by each of the two profiles 10 are respectively aligned with the through holes 21101 formed by the two connecting portions 211. The fitting 22 passes through the through holes 21101 and is threaded into the threaded holes 104 formed by the profiles 10.

[0033] Specifically, the fitting 22 includes a rod 221 and a head 222. One end of the rod 221 expands outward to form the head 222. The outer peripheral wall of the rod 221 forms an external thread. The rod 221 of the fitting 22 passes through the through hole 21101 and is threadedly installed in the threaded hole 104 formed by the profile 10.

[0034] In a preferred embodiment, an internal thread is formed on the wall of the through hole 21101 formed by the connecting part 211, and the rod part 221 of the fitting 22 is threadedly connected to both the connecting part 211 and the profile 10, thereby improving the stability of the connection between the fitting 22 and the built-in connector 21, and thus improving the connection strength between the fitting 22, the built-in connector 21, and the profile 10.

[0035] In one embodiment, the head 222 of the fitting 22 does not extend beyond the opening 102 formed by the profile 10, so that the head 222 of the fitting 22 is hidden in the assembly groove 101, maintaining the aesthetic appearance of the profile assembly surface.

[0036] As a deformable feature, the connecting portion 211 also forms a concealed hole 21102, which is coaxially arranged with the through hole 21101, and the size of the concealed hole 21102 is larger than the size of the head 222. When the fitting 22 is installed with the connecting portion 211 and the profile 10, the head 222 is recessed into the concealed hole 21102, thereby concealing the head 222 and maintaining the aesthetic appearance of the profile assembly surface.

[0037] Preferably, the connecting portion 211 has a plug-in portion 2111, which is plugged into the assembly groove 101 formed by the profile 10.

[0038] In one embodiment, the insertion portion 2111 forms the threaded hole 104.

[0039] Furthermore, the connecting portion 211 also has an extension portion 2112. The insertion portion 2111 extends towards the opening 102 to form the extension portion 2112. The extension portion 2112 and the insertion portion 2111 together form the threaded hole 104. The extension portion 2112 is engaged with the opening 102 to improve the surface flatness of the two profiles 10, thereby improving the aesthetics.

[0040] It is worth mentioning that the shape of the built-in connector 21 is adapted to the shape of the assembly groove 101 to improve the fit and contact area between the built-in connector 21 and the inner wall of the assembly groove 101, thereby improving the connection strength between the built-in connector 21 and the profile 10.

[0041] Preferably, the two profiles 10 are connected by two built-in connecting members 20. The opposite side walls of each profile 10 are recessed to form two mounting grooves 101. The abutting end faces 103 of each of the two profiles 10 abut against each other, and the two mounting grooves 101 of each profile 10 are connected and interlocked. The built-in connectors 21 of each of the two built-in connecting members 20 are located on opposite sides of the profile 10, and the fittings 22 of each of the two built-in connecting members 20 connect the built-in connectors 21 to the two profiles 10 from two opposing directions, thereby improving the connection strength between the two profiles 10.

[0042] It is understood that the number of sidewalls formed by the profile 10, the number of assembly grooves 101 formed by the profile 10, and the number of built-in connecting members 20 are the same, so that the built-in connecting members 21 provided by the built-in connecting members 20 connect the two profiles 10 circumferentially.

[0043] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
