Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a snap-fit ​​connection structure for aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles are widely used in the construction of industrial automation equipment frames, workbenches, exhibition display racks, and other structures due to their advantages such as lightweight, high strength, corrosion resistance, and ease of processing. In these applications, angle brackets are the most commonly used connectors, used to achieve vertical or arbitrary angle connections between profiles.

[0003] Traditional corner bracket structures are typically simple L-shaped metal pieces with elongated mounting slots. During installation, the corner bracket is placed at the intersection of the grooves of the two profiles to be connected, and then bolts are passed through the mounting slot of the corner bracket and tightened with boat-shaped nuts pre-installed in the profile grooves. However, this traditional installation method has significant shortcomings in practice. Because the contact between the corner bracket and the profile groove is smooth, the corner bracket's own weight or slight external disturbances can easily cause it to shift or slide before the bolts are fully tightened. Installers often need to hold the corner bracket with one hand while tightening it with the other, which not only increases the difficulty of single-person operation but also reduces assembly efficiency and accuracy.

[0004] Furthermore, standard corner brackets have fixed dimensions, and the length of their connecting arms determines the location of the connection points. In situations requiring fine-tuning of profile spacing or the presence of special installation spaces, fixed-size corner brackets cannot meet the needs, significantly limiting their versatility and applicability. To solve this problem, custom-made non-standard sized corner brackets are typically required, which undoubtedly increases costs and inventory complexity.

[0005] Therefore, this utility model proposes an aluminum alloy profile snap-fit ​​connection structure to overcome the shortcomings of the prior art. Utility Model Content

[0010] Furthermore, the guide component is fixedly connected to the bottom of the corner bracket, and the movable plate of the telescopic component is slidably connected to the bottom of the corner bracket.

[0011] Preferably, the fixing plate of the guide assembly is integrally formed on the bottom of the corner bracket.

[0012] Preferably, the guide head of the guide assembly is configured as a wedge-shaped structure with a narrowed front end, and the width of the guide head is smaller than the opening width of the second groove of the aluminum alloy profile.

[0013] Preferably, the movable plate of the telescopic component is slidably embedded in the dovetail groove opened at the bottom of the corner bracket.

[0014] Preferably, the telescopic assembly further includes a limiting ring, which is sleeved on the outer periphery of the limiting post adjacent to the second spring, and the outer diameter of the limiting ring is larger than the inner diameter of the through hole on the movable plate through which the limiting post passes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5The present invention provides an embodiment of an aluminum alloy profile snap-fit ​​connection structure, including a corner bracket 2. A guide component 5 is fixedly provided at the bottom of the corner bracket 2, and a telescopic component 6 is slidably connected to the bottom of the corner bracket 2. The corner bracket 2 serves as the installation body and bearing platform of the entire connection structure. The guide component 5 is used to provide pre-tightening positioning during installation, and the telescopic component 6 is used to adjust the connection length of the corner bracket 2.

[0030] Specifically, the corner bracket 2 has an L-shaped structure. A first groove 4 is provided on the vertical surface of the corner bracket 2 for the bolt 3 to pass through. The corner bracket 2 locks itself into the second groove 8 of the aluminum alloy profile 1 through the threaded engagement of the bolt 3 and the boat nut 7, thereby realizing the vertical connection of the two aluminum alloy profiles 1.

[0031] The guide component 5 is fixedly connected to the bottom of the corner bracket 2. The fixing plate 501 of the guide component 5 is integrally formed on the bottom of the corner bracket 2. The cavity inside the fixing plate 501 contains the first spring 502. One end of the first spring 502 is connected to the elastic plate 503. The front end of the elastic plate 503 is fixedly connected to the guide head 504. Under the elastic restoring force provided by the first spring 502, a part of the structure of the elastic plate 503 can protrude from the bottom surface of the fixing plate 501, thereby contacting the inner wall of the second groove 8 of the aluminum alloy profile 1 to generate frictional force for pre-positioning. The guide head 504 is set to a wedge-shaped structure with a narrow front end, and the width of the guide head 504 is smaller than the opening width of the second groove 8 of the aluminum alloy profile 1, so as to smoothly guide the corner bracket 2 into the second groove 8. The fixing plate 501 is also provided with a third groove 505 for the bolt 3 to pass through.

[0032] The movable plate 607 has a sliding groove 606 inside, and a limit block 605 is slidably arranged in the sliding groove 606. A limit post 602 is fixedly connected to the limit block 605. A ball head 601 is fixedly connected to the end of the limit post 602. A second spring 604 is sleeved on the outer periphery of the limit post 602. The two ends of the second spring 604 abut against the inner wall of the limit block 605 and the movable plate 607, respectively. The second spring 604 is used to provide axial reset force for the limit post 602.

[0033] The movable plate 607 is provided with a spherical groove 609 for the ball head 601 to be inserted and a limiting hole 610. The spherical groove 609 is a blind hole structure, and the limiting hole 610 penetrates through the opposite side walls of the movable plate 607. The spherical groove 609 and the limiting hole 610 are spaced apart along the sliding direction of the movable plate 607. When the ball head 601 is inserted into the spherical groove 609 or the limiting hole 610 under the elastic force of the second spring 604, the position of the movable plate 607 relative to the corner bracket 2 is locked. The movable plate 607 is also provided with a fourth groove 608 for the bolt 3 to pass through.

[0034] In a preferred embodiment, to further enhance the structural stability of the telescopic component 6 and prevent the component from falling off, a limiting ring 603 is also sleeved on the outer periphery of the limiting post 602, which is close to the second spring 604. The outer diameter of the limiting ring 603 is larger than the inner diameter of the through hole on the moving plate 607 through which the limiting post 602 passes. Through this size fit, the limiting ring 603 is blocked on one side of the inner wall of the moving plate 607, thereby effectively preventing the limiting post 602 from accidentally falling out of the moving plate 607.

[0035] As another preferred embodiment, in order to make the limiting effect of the limiting ring 603 more reliable, the outer diameter of the limiting ring 603 is larger than the outer diameter of the ball head 601, ensuring that the limiting ring 603 can provide effective structural interference even at extreme positions.

[0036] In another preferred embodiment, in order to ensure that the bolt 3 can pass through smoothly and be locked, when the corner bracket 2 is in the installation state, the first groove 4 on the corner bracket 2, the third groove 505 on the guide component 5 and the fourth groove 608 on the telescopic component 6 are coaxially arranged in the vertical direction to form a through channel for the bolt 3 to pass through.

[0037] Working principle: Before installation, the user can adjust the length of the telescopic component 6 as needed. By pressing the ball head 601, the ball head 601 is disengaged from the current spherical groove 609 or the limiting hole 610. Then, the moving plate 607 is slid. When the moving plate 607 slides to the predetermined position, the ball head 601 is released. Under the elastic force of the second spring 604, the ball head 601 automatically engages in the corresponding other positioning hole, thereby completing the length adjustment and locking.

[0038] During installation, the guide head 504 of the corner bracket 2 is aligned with the second groove 8 of the aluminum alloy profile 1 and pushed in. During the pushing process, the guide head 504 plays a guiding role. At the same time, the elastic plate 503 will contact the inner wall of the second groove 8 and be squeezed, which will compress the first spring 502. The elastic force generated by the first spring 502 applies a continuous positive pressure to the inner wall of the second groove 8 through the elastic plate 503. The resulting static friction force is sufficient to overcome the weight of the corner bracket 2 itself, so that the corner bracket 2 can be suspended at any desired position, which is convenient for the user to perform subsequent bolt tightening operations.

[0039] After positioning, bolt 3 is passed through the first groove 4, the third groove 505 and the fourth groove 608 in sequence, and screwed into the boat-shaped nut 7 pre-placed in the second groove 8 of the aluminum alloy profile 1. The bolt 3 is rotated, and the boat-shaped nut 7 is locked after rotating 90 degrees in the second groove 8. Continue to tighten the bolt 3 to firmly lock the corner bracket 2 onto the aluminum alloy profile 1, thus completing the entire connection process.
