Description

Technical Field

[0001] This utility model relates to profiles for making furniture, and more particularly to connectors for connecting profiles, and a connection structure between the profiles and the connectors. Background Technology

[0002] Aluminum profile furniture is increasingly popular due to its advantages such as environmental friendliness, noise reduction, waterproofing, fire resistance, and durability. Aluminum profile furniture primarily uses long, overlapping aluminum profiles to form a frame, upon which panels of different materials are then installed. Taking a door panel as an example, it requires four long profiles connected to form a rectangular frame, upon which wood, aluminum, or other panels are then installed. These aluminum profiles are typically connected and fixed using interlocking or connectors. However, interlocking profiles are not only structurally complex and expensive, but also have difficulty guaranteeing connection strength and requires more precise assembly and disassembly. Therefore, connectors are more commonly used. Existing L-shaped connectors insert the two ends of the L-shape into the ends of the profile and lock them in place with screws. However, apart from the screws, there are no other positioning or limiting structures between the connector and the profile, resulting in limited connection strength and easy screw loosening. Utility Model Content

[0003] The purpose of this utility model is to provide a profile connector with high connection strength, and a profile connection structure using such a profile connector, so as to improve the connection strength between profiles and improve the stability and safety of profile use.

[0004] The profile connector of this utility model includes two connecting arms. One end of each connecting arm is fixed to the other end and the other end is inserted into an adjacent profile. Each connecting arm is provided with a connecting post with a screw hole. A support arm extends from the inner side of the connection between the two connecting arms. The two sides of the end of the support arm are provided with a locking slot that abuts against the edge of the profile end.

[0005] The profile connection structure of this utility model includes two profiles with their ends facing each other, and a profile connector disposed between the opposite ends of the two profiles; the ends of the profiles are hollow and inclined; the profile connector includes two connecting arms fixed at one end to each other, the other ends of the two connecting arms are respectively inserted into the outer side of the hollow part of the two profiles, and each of the two connecting arms is provided with a connecting post with a screw hole; a support arm extends from the inner side of the connection between the two connecting arms, the side of the support arm is opposite to the end face of the profile, and a latch is provided on both sides of the end of the support arm, the two latches abutting against the inner edge of the end face of the two profiles; through holes are provided at the opposite positions of the connecting posts of the two profiles and the two connecting arms, and locking screws pass through the through holes and are screwed to the connecting posts for fixation.

[0006] The profile connector and profile connection structure described in this utility model form a frame between profiles. The profile connector is located between the ends of two profiles, with its connecting arm inserted into the outer side of the hollow interior of the profile and screwed with a locking screw to fix the profile, thus achieving the fixing effect of a traditional L-shaped connector. Simultaneously, at the connection point of the two connecting arms, i.e., the inner side of the L-shaped corner, a support arm extends. This support arm is located between the end faces of the two profiles, abutting against the ends of the profiles. This ensures the integrity, sealing, and aesthetics of the frame, and also provides support for the profiles. The support arms provide support, and when the frame deforms under stress, they support the end faces of the profiles via their sides. This not only ensures more even stress distribution but also allows the stronger support arms to withstand the pressure from the profiles, preventing damage and deformation caused by pressure between profiles. Furthermore, the support arms are equipped with latches that abut against the inner side of the profile end, creating a more effective restraint and further ensuring more even stress distribution between the support arms and the profile end face, thus protecting the profile more effectively. The profile connectors, including the connecting arms, support arms, and latches, are positioned opposite the outer, middle, and inner sides of the profile end, respectively, providing multiple points of connection and fixation. Therefore, the use of this type of profile connector and connection structure not only improves the connection strength between profiles and the stability and safety of the frame but also more effectively protects the profiles, expanding their applicability and extending their service life.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0012] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0013] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0014] This utility model proposes a profile connector.

[0015] The profile connector of this embodiment includes two connecting arms 1. One end of each connecting arm is fixed to the other end and the other end is inserted into the adjacent profile. Each connecting arm is provided with a connecting post 2 with a screw hole. A support arm 3 extends from the inner side of the connection between the two connecting arms. The two sides of the end of the support arm are provided with a latch 4 that abuts against the edge of the profile end.

[0016] like Figure 1 As shown, two connecting arms can be inserted into two adjacent profiles respectively, and are screwed into locking screws that pass through the profiles via connecting posts with screw holes, thus achieving the same fixing effect as traditional L-shaped connectors. In addition, at the connection point of the two connecting arms, i.e., the inner corner of the L-shape, a support arm extends out. The support arm abuts against the two profiles via latches. When the profiles deform under stress, the latches not only provide restraint, but the support arms also provide support. This effectively improves the connection strength and compressive and bending resistance between the profiles, and also reduces the risk of locking screws coming loose. Therefore, the use of this type of profile connector can effectively improve the stability and safety of profile use.

[0017] The aforementioned profile connector has a connecting arm 1 located on the outward side inside the profile end, a support arm 3 with its side facing the end face of the profile, and a latch 4 located on the inner edge of the profile end face. These three positions are respectively opposite to the outer, middle, and inner sides of the profile end, forming multiple connection, support, and fixation points, thereby further improving the connection strength and better protecting the profile, reducing the possibility of damage.

[0018] The aforementioned profile connector has two connecting arms 1 that extend outward from the direction opposite to the support arm 3, or the support arm 3 can be directly connected to one end of the two connecting arms and extended outward, so that the extended end and the outer side of the connecting arm form a stepped structure. The step can abut against the outer edge of the profile end face, forming a limiting effect similar to a bayonet. It can also make the outer side of the frame composed of the profile connector and the profile flatter and improve the aesthetics of the frame.

[0019] The aforementioned profile connector features a limiting block 5 extending into the profile at the end of the support arm 3, adjacent to its end face. A locking slot 4 is located between the limiting block and the end face of the support arm, ensuring both limiting and support while also providing a similar support and connection effect to the connecting arm. A screw hole (not shown) can also be provided on the limiting block for securing it to the profile with locking screws, further enhancing the connection strength. The support arm 3 also has several perforated holes to reduce the weight of the profile connector and provide more usage options to meet different personalized needs.

[0020] This utility model also proposes a profile connection structure.

[0021] The profile connection structure of this embodiment includes two profiles 20 with their ends facing each other, and a profile connector 10 disposed between the opposite ends of the two profiles; the ends of the profiles are hollow and inclined; the profile connector includes two connecting arms 1 fixed at one end to each other, the other ends of the two connecting arms are respectively inserted into the outer side of the hollow part of the two profiles, and each of the two connecting arms is provided with a connecting post 2 with a screw hole; a support arm 3 extends from the inner side of the connection point of the two connecting arms, the side of the support arm is opposite to the end face of the profile, and a latch 4 is provided on both sides of the end of the support arm, the two latches abut against the inner edge of the end face of the two profiles; through holes 21 are provided at the opposite positions of the connecting posts of the two profiles and the two connecting arms, and locking screws 30 pass through the through holes and are screwed and fixed to the connecting posts.

[0022] like Figure 2-4As shown, the profiles are connected to form a frame via profile connectors. The profile connectors are located between the ends of two profiles, with connecting arms inserted into the outer side of the hollow interior of the profile and screwed into locking screws to secure the profile. Simultaneously, support arms are positioned between the end faces of the two profiles, abutting against the ends of the profiles. This ensures the integrity, sealing, and aesthetics of the frame, while also providing support for the profiles. When the frame deforms under stress, the support arms support the end faces of the profiles through their sides, resulting in more even stress distribution and allowing the higher-strength support arms to withstand the pressure on the profiles, preventing damage and deformation caused by pressure between the profiles. Furthermore, the support arms have latches that abut against the inner side of the profile end, creating a more effective limit and ensuring more even stress distribution between the support arms and the profile end face, thus more effectively protecting the profiles. The profile connectors, with connecting arms, support arms, and latches respectively facing the outer, middle, and inner sides of the profile ends, form multiple connection and fixation points. It is evident that the use of this type of profile connection structure can not only improve the connection strength between profiles and the stability and safety of the frame, but also more effectively protect the profiles, expand their application range and extend their service life.

[0023] The shape of the outer side of the connecting arm 1 in the aforementioned profile connection structure is consistent with the shape of the outward-facing side of the hollow interior of the profile 20, such as... Figure 1 , 3 As shown, at least one profile 20 has an outward-facing arc shape, meaning both its outer surface and its inner facing side are arc-shaped. The outer surface of the connecting arm 1 is also correspondingly arc-shaped, creating an arc-shaped structure on one side of the frame. This not only improves aesthetics and meets different personalized needs but also better reduces the risk of bumps and scratches, thus better protecting the user. Similarly, the connection point of the two connecting arms 1 extends outward in the direction opposite to the support arm 3, and the end face of the extended end is arc-shaped, further reducing the risk of bumps.

[0024] like Figure 3 As shown, protruding positioning strips 22 are provided on both sides of the hollow interior of the profile 20, and recessed positioning grooves 6 are provided on both sides of the inner side of the connecting arm 1. The connecting arm is located between the positioning strips and the inner wall of the profile facing outward, and the positioning grooves are fitted onto the positioning strips. This facilitates positioning during assembly and also improves the connection strength between the profile and the profile connector.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
