Description

Technical Field

[0001] This application relates to the technical field of corner fittings, and in particular to a detachable corner fitting for installing metal honeycomb composite panels. Background Technology

[0002] Metal honeycomb composite panels are high-performance composite panels with a honeycomb sandwich structure. They are made by bonding high-strength alloy aluminum plates or other metals as the face and back plates with honeycomb core materials under high temperature and pressure. Corner fittings are required when installing metal honeycomb composite panels.

[0003] A metal composite plate corner connector, disclosed on the Chinese Patent Network (publication number CN210343942U), includes a first groove, a support block, a second groove, a first fixing groove, a second fixing groove, and a positioning wedge. The first groove is located on the upper side of the right end face of the connector body, and the second groove is located on the lower side of the right end face of the connector body. The first groove is located in the middle of the right end face of the connector body. A support block is installed between the first groove and the first fixing groove, and a support block is installed between the second groove and the first fixing groove. A positioning wedge is installed on the lower side of the first groove. The positioning wedge is installed at the connection between the first metal composite plate and the second metal composite plate. The right end face of the positioning wedge has a second fixing groove. This design solves the problem of insufficient firmness and stability of the original metal composite plate corner connection. This utility model has a reasonable structure, facilitates the corner connection of metal composite plates, and provides a stable and firm connection.

[0004] The solution also has the following problems: the connector fixes the composite panel with fastening bolts, which is convenient for disassembly and assembly. However, the connector is at a fixed angle, which is inconvenient when installing two composite panels that are not perpendicular to each other, thus having certain drawbacks.

[0005] Therefore, in order to solve the above problems, this application provides a detachable corner piece for installing metal honeycomb composite panels. Utility Model Content

[0006] The purpose of this utility model is to provide a detachable corner piece for installing metal honeycomb composite panels, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable corner piece for installing metal honeycomb composite panels, comprising a base, a fixed plate installed at one top end of the base, a movable plate rotatably connected to one top end of the fixed plate, fixed frames symmetrically installed at both ends of the outer side of the movable plate, a sliding rod installed between the inner sidewalls of the fixed frames, a slider installed on the outer ring surface of the sliding rod inside the fixed frame, fixed frames symmetrically installed on both sides of the top of the base away from the fixed plate, symmetrically provided limit grooves on the wider outer side surfaces of the fixed frames, a threaded rod installed between the inner sidewalls of the fixed frames, a movable block installed on the outer ring surface of the threaded rod inside the fixed frame, fixed posts installed at both ends of the movable block inside the two limit grooves, and an adjusting rod installed on the outer ring surface of the fixed posts.

[0008] Preferably, a rotating block is installed on the narrower side of the outer side of the fixed frame. The rotating block's shaft passes through the fixed frame and is connected to one end of the threaded rod. The outer ring surface of the threaded rod is threadedly connected to the interior of the movable block.

[0009] Preferably, the bottom two ends of the adjusting rod are rotatably connected to the outside of the two fixed posts, the end of the adjusting rod away from the two fixed posts is rotatably connected to the outside of the slider, and the outer ring surface of the slider is slidably connected to the inside of the slider.

[0010] Preferably, both the fixed plate and the movable plate have sliding grooves at their inner ends. A limiting plate is installed inside the sliding groove, and a connecting plate is installed at one outer end of the limiting plate. An auxiliary support plate is installed at the end of the connecting plate that extends away from the limiting plate to the outside of the sliding groove. The limiting plate will not detach from the inside of the sliding groove.

[0011] Preferably, mounting holes are provided at the four outer corners of the fixed plate and the movable plate, as well as on the outer side of the auxiliary support plate, and fixing bolts are provided in the mounting holes to fix the corner piece to the composite plate.

[0012] Preferably, anti-slip pads are installed on the outer surfaces of the fixed plate and the movable plate that are in close contact with the side of the composite plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This detachable corner piece for installing metal honeycomb composite panels works by rotating a rotating block, which drives a threaded rod to rotate synchronously. The threaded engagement between the threaded rod and the movable block converts the rotational motion into axial movement of the movable block. As the movable block moves, the fixed column slides within the limiting groove, and the adjusting rod moves synchronously, pushing the slider along the sliding rod. The sliding engagement between the sliding rod and the slider ensures the stable movement of the adjusting rod, thereby achieving angle adjustment of the movable plate. This facilitates the installation of composite panels with different splicing angles. The auxiliary support plate moves along the sliding groove via the connecting plate and the limiting plate, adjusting its position according to the size of the composite panel to enhance the connection stability between the corner piece and the composite panel. The corner piece is secured to the composite panel by fixing bolts passing through the mounting holes to ensure a firm connection. The mounting holes of the auxiliary support plate are also reinforced with fixing bolts, making disassembly and assembly convenient. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0021] A detachable corner bracket for installing metal honeycomb composite panels, as shown in the reference. Figure 1 - Figure 4The system includes a base 1, a fixed plate 2 installed at one top end of the base 1, a movable plate 3 rotatably connected to the top end of the fixed plate 2, fixed frames 4 symmetrically installed at both ends of the outer side of the movable plate 3, a sliding rod 5 installed between the inner side walls of the fixed frame 4, a slider 6 installed on the outer ring surface of the sliding rod 5 and inside the fixed frame 4, fixed frames 7 symmetrically installed on both sides of the top of the base 1 away from the fixed plate 2, limit grooves 701 symmetrically opened on the wider outer side surface of the fixed frame 7, a threaded rod 8 installed between the inner side walls of the fixed frame 7, a movable block 9 installed on the outer ring surface of the threaded rod 8 and inside the fixed frame 7, fixed posts 10 installed at both ends of the movable block 9 and inside the two limit grooves 701, and an adjusting rod 11 installed on the outer ring surface of the fixed posts 10.

[0022] Reference Figure 2 - Figure 3 A rotating block 12 is installed on the narrower side of the fixed frame 7. The rotating shaft of the rotating block 12 passes through the fixed frame 7 and is connected to one end of the threaded rod 8. The outer ring surface of the threaded rod 8 is threadedly connected to the inside of the movable block 9. When the rotating block 12 is rotated, the threaded rod 8 rotates synchronously. The threaded engagement between the threaded rod 8 and the movable block 9 converts the rotational motion into the axial movement of the movable block 9, thereby driving the adjustment rod 11 and the angle adjustment of the movable plate 3. The bottom two ends of the adjustment rod 11 are rotatably connected to the outside of the two fixed columns 10. The end of the adjustment rod 11 away from the two fixed columns 10 is rotatably connected to the outside of the slider 6. The outer ring surface of the slide rod 5 is slidably connected to the inside of the slider 6. When the movable block 9 moves, the fixed column 10 slides in the limiting groove 701. The adjustment rod 11 moves synchronously, pushing the slider 6 to move along the slide rod 5. The sliding engagement between the slide rod 5 and the slider 6 ensures the stable movement of the adjustment rod 11, thereby realizing the angle adjustment of the movable plate 3.

[0023] Reference Figure 1 - Figure 4 Both ends of the fixed plate 2 and the movable plate 3 are provided with sliding grooves 13. A limiting plate 14 is installed inside the sliding groove 13, and a connecting plate 15 is installed on one end of the limiting plate 14. The end of the connecting plate 15 away from the limiting plate 14 extends to the outside of the sliding groove 13 and is equipped with an auxiliary support plate 16. The limiting plate 14 will not detach from the inside of the sliding groove 13. The auxiliary support plate 16 moves along the sliding groove 13 through the connecting plate 15 and the limiting plate 14, and adjusts its position according to the size of the composite plate to enhance the connection stability between the corner piece and the composite plate. The limiting plate 14 prevents the auxiliary support plate 16 from falling out of the sliding groove 13.

[0024] Reference Figure 1Mounting holes 17 are provided at the four corners of the fixed plate 2 and the movable plate 3, as well as on the outside of the auxiliary support plate 16. Fixing bolts 18 are installed in the mounting holes 17 to secure the corner piece to the composite plate. The composite plate is then attached to the outer surfaces of the fixed plate 2 and the movable plate 3. The fixing bolts 18 pass through the mounting holes 17 to secure the corner piece to the composite plate, ensuring a firm connection. The mounting holes 17 of the auxiliary support plate 16 are also reinforced with fixing bolts 18. Anti-slip pads 19 are installed on the outer surfaces of the fixed plate 2 and the movable plate 3, close to the side of the composite plate. The anti-slip pads 19 increase the friction between the corner piece and the composite plate, preventing slippage or misalignment during installation and ensuring the composite plate remains stable when adjusting the angle, thus improving installation accuracy and safety.

[0025] The implementation principle of the detachable corner bracket for installing metal honeycomb composite panels in this application embodiment is as follows: When using the corner bracket to install metal honeycomb composite panels at different angles, rotating the rotating block 12 drives the threaded rod 8 to rotate synchronously. The threaded engagement between the threaded rod 8 and the movable block 9 converts the rotational motion into the axial movement of the movable block 9. When the movable block 9 moves, the fixed column 10 slides within the limiting groove 701, and the adjusting rod 11 moves synchronously, pushing the slider 6 to move along the sliding rod 5. The sliding engagement between the sliding rod 5 and the slider 6 ensures the stable movement of the adjusting rod 11, thereby realizing the angle adjustment of the movable plate 3, which facilitates the installation of composite panels with two different splicing angles. The auxiliary support plate 16 moves along the sliding groove 1 through the connecting plate 15 and the limiting plate 14. 3. The position is adjusted according to the size of the composite panel to enhance the connection stability between the corner piece and the composite panel. The limiting plate 14 prevents the auxiliary support plate 16 from falling out of the slide groove 13. The corner piece and the composite panel are fastened with fixing bolts 18 through the mounting holes 17 to ensure a firm connection. The mounting holes 17 of the auxiliary support plate 16 are also reinforced with fixing bolts 18. The anti-slip pad 19 increases the friction between the corner piece and the composite panel to prevent sliding or misalignment during installation, ensuring that the composite panel remains stable when adjusting the angle, improving installation accuracy and safety, and facilitating disassembly and assembly. The external helix opening angle of the threaded rod 8 is 20 degrees, and the thread self-locking condition meets the following formula: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
