Description

Technical Field

[0001] This application relates to the field of connector technology, and more particularly to connector assemblies for connecting profiles. Background Technology

[0002] Industrial aluminum profiles are alloy materials with aluminum as the main component, produced through hot melting and extrusion to obtain aluminum materials with different cross-sectional shapes. Typically, multiple aluminum profiles are interconnected to form a support frame. First, the end face of one profile abuts against the side wall of another profile. Then, bolts are screwed into the two profiles from the other profile's sidewall towards the first profile's sidewall, connecting the two profiles together. The pressure exerted by the bolts on the two profiles is relatively concentrated, the contact area is small, and the connection strength between the two profiles is provided by the bolts, resulting in relatively low connection strength and weak support frame strength.

[0017] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0018] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0019] 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.

[0020] refer to Figures 1 to 4 A preferred embodiment of the support frame according to this application will be described in detail below. The support frame includes a profile assembly 10 and at least one set of connecting components 20 for connecting the profiles. The profile assembly 10 includes at least one first profile 11 and at least one second profile 12. Each second profile 12 is connected to a first profile 11 via at least one set of the connecting components 20. To facilitate understanding of the technical solution of this application by those skilled in the art, the following embodiment uses the connection of a second profile 12 to a first profile 11 via at least one set of the connecting components 20 as an example. However, this does not mean that the support frame is limited to having only two profiles.

[0021] The first profile 11 forms a first mounting wall 111, and the second profile 12 forms a second mounting wall 121. The end face of the second profile 12 remains in contact with the first mounting wall 111 formed by the first profile 11, and the second mounting wall 121 intersects with the first mounting wall 111.

[0022] Each of the connecting assemblies 20 for connecting profiles includes a connector 21 and two assembly structures 22. The connector 21 has two connected abutment portions 211, and each abutment portion 211 forms an abutment wall 2111.

[0023] The connector 21 abuts against the first mounting wall 111 formed by the first profile 11 and the second mounting wall 121 formed by the second profile 12, respectively, through the abutment walls 2111 formed by the two abutment portions 211. One assembly structure 22 is installed between the first profile 11 and one abutment portion 211; another assembly structure 22 is installed between the second profile 12 and another abutment portion 211, such that the assembly structure 22 connects the first profile 11 and the second profile 12 together by means of the connector 21. The connector 21 disperses the pressure of the assembly structure 22 and increases the contact area between the connector 21 and the first profile 11 and the second profile 12, thereby improving the connection strength between the assembly structure 22 and the profile assembly 10 through the connector 21.

[0024] It is worth mentioning that the included angle between the two abutting walls 2111 is the same as the included angle between the first mounting wall 111 formed by the first profile 11 and the second mounting wall 121 formed by the second profile 12. In this way, the connector 21 can maintain a tight fit with the joint of the first profile 11 and the second profile 12 with a maximum contact area, thereby improving the stability of the connection and the load-bearing capacity of the support frame. Depending on actual assembly requirements, the first profile 11 and the second profile 12 can be connected at any angle via the connecting assembly 20 for connecting the profiles.

[0025] In one embodiment, the first profile 11 and the second profile 12 are vertically connected, that is, the included angle between the first mounting wall 111 and the second mounting wall 121 is 90 degrees; the included angle between the two abutting walls 2111 of the connector 21 is 90 degrees.

[0026] In another embodiment, the included angle between the first mounting wall 111 formed by the first profile 11 and the second mounting wall 121 formed by the second profile 12 is 135 degrees; the included angle between the two abutting walls 2111 of the connector 21 is 135 degrees.

[0027] As deformable, the included angle between the first mounting wall 111 formed by the first profile 11 and the second mounting wall 121 formed by the second profile 12 is forty-five degrees; the included angle between the two abutting walls 2111 of the connector 21 is forty-five degrees.

[0028] It is worth mentioning that each of the connectors 21 also forms a reinforcing portion 212, which extends between the two connected abutment portions 211. The reinforcing portion 212 formed by the connector 21 and the two abutment portions 211 form a triangular structure. Since the triangular structure has stability, it can improve the stability and support strength of the connector 21, thereby improving the firmness of the connection between the first profile 11 and the second profile 12.

[0029] Preferably, the connector 21 forms at least one weight-reducing hole 2101 to reduce the weight of the connector 21 and reduce the amount of material used to manufacture the connector 21.

[0030] Specifically, the assembly structure 22 includes a locking member 221, which has a rod portion 2211 and a head 2212. One end of the rod portion 2211 expands outward to form the head 2212, and the outer peripheral wall of the rod portion 2211 forms an external thread. Each of the abutment portions 211 forms a through hole 21101, through which the rod portion 2211 of the locking member 221 passes.

[0031] In one embodiment, both the first profile 11 and the second profile 12 have threaded holes. A set of locking fasteners 221 provided in the assembly structure 22 passes through the through hole 21101 formed by one of the abutment portions 211 and is threadedly connected to the threaded hole formed by the first profile 11; another set of locking fasteners 221 provided in the assembly structure 22 passes through the through hole 21101 formed by the other abutment portion 211 and is threadedly connected to the threaded hole formed by the second profile 12.

[0032] In another embodiment, each assembly structure 22 further includes a connecting member 222. The first profile 11 and the second profile 12 each form at least one assembly groove 101 and an opening 102 communicating with the assembly groove 101.

[0033] The connector 222 is installed in the mounting groove 101, and the connector 222 forms a mounting hole 22201. The inner wall of the mounting hole 22201 forms an internal thread that matches the rod portion 2211. The rod portion 2211 of the locking fastener 221 passes through the through hole 21101 and extends into the mounting hole 22201 formed by the connector 222 from the opening 102, and the rod portion 2211 of the locking fastener 221 is threadedly connected to the connector 222.

[0034] Specifically, the connector 222 is located at the end of the first profile 11 / second profile 12 and is held in an alignment with the port of the mounting groove 101 formed by the first profile 11 / second profile 12; then it moves toward sliding into the mounting groove 101, so that the connector 222 is inserted into the mounting groove 101. The rod portion 2212 of the locking fastener 221 passes through the through hole 21101 and is aligned with the mounting hole 22201 formed by the connector 222. As the locking fastener 221 moves toward the rod portion 2211 into the mounting hole 22201, the connector 222 abuts against the top wall of the mounting groove 101 and the head 2212 abuts against the connector 21, thereby the locking fastener 221 and the connector 222 cooperate to lock the connector 21 and the first profile 11 / second profile 12. Compared to the previous embodiment, in this embodiment, neither the first profile 11 nor the second profile 12 needs to have threaded holes, so that the first profile 11 and the second profile 12 can maintain their original shape and the supporting strength of the first profile 11 and the second profile 12 is not affected, and the disassembly and assembly are quick and convenient.

[0035] In a preferred embodiment, the cross-section of the connector 222 in the plane extending along the mounting groove 101 is polygonal, such as quadrilateral, to prevent the connector 222 from being rotated within the mounting groove 101 by the locking fastener 221.

[0036] Preferably, each of the abutment portions 211 is separated by the reinforcing portion 212 into an extension portion 2112 and a connecting portion 2113. The extension portions 2112 of each of two adjacent abutment portions 211 are connected to each other, and the connecting portion 2113 is formed at the ends of the two abutment portions 211 that are far apart from each other, wherein the extension portion 2112 and the reinforcing portion 212 together form the weight-reducing hole 2101.

[0037] In one embodiment, the extension 2112 forms the through hole 21101. For the larger connector 21, the weight-reducing hole 2101 is larger, allowing the installer's hand to reach into the weight-reducing hole 2101 to perform the installation and removal of the fastener 221. In this way, the reinforcement 212 can cover the fastener 221, thereby improving the aesthetics and safety of the support frame.

[0038] As deformable, the connecting part 2113 forms the through hole 21101. For the connector 21 with a small volume, the size of the weight-reducing hole 2101 is small. The weight-reducing hole 2101 is not convenient for the worker's hand to reach in. Therefore, the through hole 21101 formed in the connecting part 2113 can facilitate the worker to install and remove the locking fastener 221.

[0039] Preferably, the connector 21 further forms a hidden hole, which is coaxially arranged with the through hole 21101. The size of the hidden hole is larger than the size of the head 2212. When the locking fastener 221 and the connecting member 222 cooperate to lock the connector 21 and the first profile 11 / second profile 12, the head 2211 of the locking fastener 221 is recessed into the hidden hole to improve the aesthetics after assembly.

[0040] Preferably, one of the first profiles 11 is connected to one of the second profiles 12 through two sets of connecting components 20 for connecting profiles, thereby enhancing the connection strength between the first profile 11 and the second profile 12.

[0041] Specifically, the second profile 12 forms two opposing second mounting walls 121. The connectors 21 of each of the two sets of connecting assemblies 20 for connecting profiles abut against the two second mounting walls 121 formed by the second profile 12 and the first mounting wall 111 formed by the first profile 11. The angles between the two second mounting walls 121 formed by the second profile 12 and the first mounting wall 111 formed by the first profile 11 are complementary. The angles between the two abutting walls 2111 formed by the connectors 21 of each of the two sets of connecting assemblies 20 for connecting profiles are complementary.

[0042] In one embodiment, the first profile 11 and the second profile 12 are vertically connected. That is, the second profile 12 forms two second mounting walls 121, each forming a 90-degree angle with the first mounting wall 111 formed by the first profile 11. The connecting members 21 of the two sets of connecting assemblies 20 for connecting the profiles each form two abutment walls 2111, each forming a 90-degree angle.

[0043] In another embodiment, the angles between the two second mounting walls 121 formed by the second profile 12 and the first mounting wall 111 formed by the first profile 11 are 135 degrees and 45 degrees, respectively. Similarly, the included angles between the two abutment walls 211 formed by the connectors 21 of each of the two sets of connecting assemblies 20 for connecting profiles are 135 degrees and 45 degrees, respectively.

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.
