Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profiles, in particular to a quick connection structure in profile construction. Background Art

[0002] Aluminum profile is an aluminum material with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. There is usually a center hole in the middle of the aluminum profile. Industrial aluminum profiles have a very wide range of uses and strong versatility. Industrial aluminum profiles are of many varieties and full specifications, suitable for use in various types of building construction. When assembling into products, a combination of special bolts and connecting accessories is generally used. For example, when two aluminum profiles need to be spliced or connected and fixed at a certain angle, the usual connection structure is: the two ends of the connecting plate are connected to the two aluminum profiles by bolts respectively. However, due to the low strength of the connecting plate, the above structure is easy to deform, causing the position of the two aluminum profiles to be offset, and a single bolt is not enough to meet the connection positioning requirements.

[0003] Of course, in some public places or objects with higher requirements, the connection between profiles is often carried out in a more reliable and concealed way to ensure safety and reliability, such as the construction of exhibition booths and the connection between furniture profiles. Patent document 202110831097.0 discloses a linear connection structure of profiles, including a profile connection part and a profile connector; the profile connection part includes a limit plate formed in the cavity; a first through hole is provided in the middle of the limit plate, which passes through the limit plate in the axial direction of the profile; the profile connector includes a connecting sleeve and two connecting auxiliary parts symmetrically arranged along the radial center section of the connecting sleeve; the above structure realizes a very stable connection, but it has more parts and a complex structure. It is not suitable for occasions where disassembly and assembly are frequent and cost-effective. Summary of the Invention

[0004] In order to overcome the above-mentioned defects, the utility model provides a novel profile connection structure which is convenient and quick to disassemble and has a high cost performance. After the two aluminum profiles are connected, they are not prone to deviation and have a stable structure.

[0005] A profile connection structure, comprising two profiles and a connection mechanism, wherein both ends of the profiles have connection holes for accommodating the connection mechanism, the connection mechanism comprising a connector lower plate and a connector upper plate, the connector lower plate and the connector upper plate being connected in series by rivets and movable along the rivets within the length of the rivets, a spring being provided between the connector lower plates and the connector upper plates, the spring being sleeved on the rivets;

[0006] A screw sleeve and a screw rod are provided. Through holes are respectively opened on both sides of the upper plate of the connector. The screw sleeve is fixedly installed in the through hole. The screw rod passes through the screw sleeve and the front end acts on the lower plate of the connector.

[0007] The profile is provided with an adjustment hole. When connecting, the two ends of the lower plate and the upper plate of the connector are respectively inserted into the connection holes on the end face of the profile and the through hole of the upper plate of the connector corresponds to the position of the adjustment hole on the profile. By adjusting the screw in the through hole, the lower plate and the upper plate of the connector are tightened and connected to the inner wall of the profile, thereby realizing the fixed connection between the two profiles.

[0008] In order to make the structural connection more stable and reliable, the rivets are connected to the center positions of the lower plate and the upper plate of the connector, and the screws are located on both sides of the rivets.

[0009] As a further improvement of the present invention, the upper end of the screw sleeve extends upward and, after connection, is inserted into the adjustment hole on the profile. This makes positioning more convenient during the connection process and ensures the reliability of the longitudinal connection between the two profiles.

[0010] As a preferred embodiment of the present invention: the upper plate of the connecting piece and the lower plate of the connecting piece are both provided with a connecting body and supporting wings located on both sides of the connecting body.

[0011] As a further improvement of the present invention: a support block is provided at the end of the support wing, and the connection surface of the support block matches the inner wall of the connection hole to form a surface contact, which makes the connection between the two more stable and reliable by increasing the contact surface.

[0012] As a further improvement of the present invention, to prevent displacement or offset after connection: burrs are provided on the connection surface of the support block.

[0013] In order to further ensure that the profile does not deviate or rotate after connection, the cross-section of the connecting hole is a rectangular structure, the cross-section of the support block is also a rectangular structure, and the support block is supported at the top corner of the profile.

[0014] As a further improvement of the present invention, in order to prevent the screw from falling off during rotation, a convex ring is provided at the front end of the screw.

[0015] According to the above technical solution, the utility model has the following effects:

[0026] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0028] Furthermore, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances. Example

[0029] Reference Figure 1 and Figure 3As shown, this embodiment describes in detail a linear connection structure of two profiles, including two profiles 7 and a connection mechanism, such as Figure 3 As shown, the profile 7 has connection holes 71 at both ends to accommodate the connection mechanism, and adjustment holes 72 are provided on both sides of the upper end surface of the profile. The specific position of the adjustment holes 72 on the profile matches the length from the ends of the connector upper plate to the screw sleeve position, thereby ensuring that the screw sleeve 4 and the adjustment holes 72 are aligned after the connector upper plate 2 is inserted into the connection hole.

[0030] The profile 7 used in this embodiment is a square profile, and the connecting hole 71 is also a square structure. Of course, this article does not make specific requirements on the profile structure, and the connecting hole involved in the profile can be square, or circular or other regular shapes.

[0031] Reference Figure 1 and Figure 2 As shown, the connecting mechanism includes a connecting lower plate 1, a connecting upper plate 2, a rivet 6, a spring 5, a screw sleeve 4 and a screw 3. The connecting lower plate 1 and the connecting upper plate 2 are connected in series through the rivet 6. Figure 2 As shown, rivet 6 has a head at one end and a reversed buckle at the other end, securing the lower and upper plates 1 and 2 to the rivet 6. The combined thickness of the two plates is less than the length of the rivet, allowing them to move on the rivet 6. To ensure that the two plates do not collide under normal circumstances and to prevent rivet 6 from being exposed to the outside, potentially injuring the operator, a spring 5 is designed on rivet 6. Spring 5 is sleeved onto rivet 6, with its two ends acting on the lower and upper plates 1 and 2, respectively. Of course, the spring 5 here is only a preferred option; other types of elastic elements could also be used.

[0032] For easy operation and precise positioning, such as Figure 5 As shown, the rivet hole 25 on the upper plate 2 of the connector in this embodiment that cooperates with the rivet is designed at the center position of the upper plate 2 of the connector. Except for the lack of the through hole 26, the other structures of the lower plate of the connector in this embodiment are the same as those of the upper plate 2 of the connector. This embodiment is specifically described with respect to the upper plate of the connector, and the structure of the lower plate of the connector can refer to the structure of the upper plate of the connector.

[0033] like Figure 1 and Figure 5As shown, the connector upper plate 2 has through holes 26 on both sides. For ease of processing, the distances from the centers of the through holes on both sides to the centers of the rivet holes are the same in this embodiment. The distances from the centers of the through holes to the centers of the rivet holes match the distances from the centers of the adjustment holes on the profile to the end faces of the profiles on the same side. This ensures that after the two ends of the connector upper plate 2 are inserted into the profiles 7, the two profiles 7 cover the entire connector upper plate 2, making the connection more reliable and aesthetically pleasing. Of course, the distances from the centers of the through holes on both sides to the centers of the rivet holes can also be different, but it is necessary to ensure that the distances from the centers of the through holes 26 on the same side to the centers of the rivet holes 25 match the distances from the centers of the adjustment holes 72 on the profile to the end faces on the same side, thereby ensuring that the upper end of the screw sleeve 4 can be inserted into the adjustment holes 72 after connection.

[0034] like Figure 1 As shown: There are screw sleeves 4 and screw rods 3. The screw sleeves 4 are fixed in the through hole 26 and do not rotate. The screw rods 3 pass through the screw sleeves 4 and the front end acts on the lower plate 1 of the connector. By rotating the screw 3, the distance between the upper plate 2 and the lower plate 1 of the connector can be adjusted. In order to facilitate the alignment of the adjustment hole 72 and the through hole 26, the upper end of the screw sleeve 4 extends out of the upper plate 2 of the connector and is used to be inserted into the corresponding adjustment hole 72 of the profile when connecting. Figure 6 As shown: In order to ensure that the screw does not fall, a convex ring 31 is provided at the front end of the screw 3.

[0035] like Figure 4 As shown: the upper plate 2 of the connector includes a connecting body 21 and support wings 22 located on both sides of the connecting body. The ends of the support wings are provided with support blocks 23, and the connecting surface of the support blocks is provided with burrs 24. In this embodiment, since the connecting hole 71 is a rectangular structure, the structure of the support block 23 is also a rectangular structure. In this embodiment, the width of the two support wings matches the width of the connecting hole 71. Figure 3 As shown, when connected, the two ends of the connector lower plate 1 and the connector upper plate 2 are respectively inserted into the connecting holes 71 on the end faces of the profile and the upper extension of the screw sleeve is inserted into the adjusting hole 72 on the profile. By adjusting the screw 3, the distance between the connector lower plate 1 and the connector upper plate 2 is increased and finally the four supporting wings of the connector lower plate and the connector upper plate are just supported on the four top corners of the profile connecting hole 71, thereby realizing the tension connection between the connecting mechanism and the profile 7, thereby also fixing the two profiles together.

[0036] like Figure 3 As shown: In this embodiment, under normal circumstances, the upper extension of the screw sleeve 4 only needs to be inserted into the adjustment hole in the profile. However, when the profile is thin, the upper extension of the screw sleeve can extend beyond the outer end surface of the adjustment hole, that is, the upper end surface of the profile in this embodiment, to further ensure the reliability of the connection. In addition, the tensioning effect of the screw rod 3 can cause the support wings 22 to deform slightly to the sides, thereby ensuring the tensioning effect.

[0037] For the convenience of operation, the utility model can make the overall height of the connection mechanism greater than the height 71 of the profile connection hole under normal circumstances. When connecting, the spring is compressed to be inserted into the connection hole, thereby ensuring the alignment operation of the upper extension part of the screw sleeve and the adjustment hole.

[0038] When the utility model needs to be disassembled, the connecting mechanism and the profile can be separated by loosening the screw rod and pressing the screw sleeve downward to separate from the adjustment hole.

[0039] This embodiment uses a rectangular connecting hole as an example. If the connecting hole is a circular hole, the corresponding supporting block structure should also be designed to be arc-shaped to match the circular hole. Other structures will not be discussed in detail in this case.

[0040] Obviously, the embodiments described above are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
