Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, specifically relating to a holeless connector for honeycomb panels. Background Technology

[0002] Honeycomb panels are made by firmly bonding two thinner face sheets to both sides of a thicker honeycomb core material; they are also known as honeycomb sandwich structures. Honeycomb panels are a new type of decorative panel and a relatively high-grade exterior wall decoration material. The material is very environmentally friendly and has advantages such as heat insulation and resistance to deformation over time.

[0003] Because honeycomb panels have a hollow structure and lack the dense structure of traditional wood panels, their porous structure has insufficient mechanical load-bearing capacity, making it impossible for ordinary panel connectors to effectively connect with the panel. Patent CN 117905762A discloses an embedded connector for frameless honeycomb panel furniture, including set screws, a support housing, a connecting rod, and a pre-embedded nut. In use, the support housing and the pre-embedded nut need to be installed in the panel first, and then holes for the set screws to pass through are made in the panel so that they are aligned with the positioning lock head and the holes in the support housing after the connecting rod is inserted. This solution is quite cumbersome during installation and requires many parameters to be calibrated. Furthermore, driving multiple set screws into the panel will affect the aesthetics. For honeycomb panels, the panel thickness is not very thick, and the interior is hollow, so the stability of the set screws is also difficult to guarantee.

[0004] To address the problems of cumbersome installation and inconvenient use of existing honeycomb panel connectors, it is necessary to improve the structure of the connectors to solve the current technical issues. Utility Model Content

[0005] The purpose of this utility model is to provide a holeless connector for honeycomb panels. Simply insert two mounting plates with limiting plates into the two honeycomb panels to be connected, and then push the adjusting component to firmly clamp the two limiting plates into the honeycomb panel in a figure-eight shape. Then, the bolt head of the adjusting component on the connector of one honeycomb panel is clamped into the other mounting plate to complete the connection. The operation is simple and convenient, and after installation, there are no holes or screws on the surface, making it simple and beautiful.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a honeycomb panel holeless connector, including a mounting plate, one end of which has at least one through groove, at least one through groove is symmetrically hinged to two limiting plates by two hinge axes, and the hinge axes are far from the center of the through groove, the mounting plate has a through hole penetrating the through groove, at least one corner of the limiting plate extends to the axis of the through hole, the through hole is provided with an adjusting member that abuts against the limiting plate, and the two limiting plates are adjustablely embedded in the honeycomb panel by the adjusting member (5).

[0007] To better realize this utility model, the mounting plate is provided with a sliding groove at the end away from the limiting plate, the adjusting component adopts a bolt structure, and the width of the sliding groove is not less than the bolt head diameter of the adjusting component;

[0008] The slide groove is provided with a partition plate parallel to the bottom surface, and the distance between the partition plate and the bottom surface of the slide groove is equal to the maximum thickness of the bolt head of the adjusting component;

[0009] The partition has a U-shaped notch, the width of which is equal to the thread diameter of the adjusting member, and the inlet end of the U-shaped notch has a V-shaped structure.

[0010] To better realize this utility model, the mounting plate has a mounting opening extending through two opposite sides, and a nut adapted to the adjusting member is provided in the mounting opening. The adjusting member can be adjusted to move within the through hole by means of the nut.

[0011] The mounting port is provided with a fixing block, and the fixing block has a groove that is adapted to the nut.

[0012] To better realize this utility model, each of the two limiting plates in the through groove is fitted with an elastic reset ring close to the mounting plate.

[0013] To better realize this utility model, the limiting plate has at least one acute angle.

[0014] To better realize this utility model, the two intersecting parts of the acute angle have a cutting edge and a blunt edge, respectively.

[0015] To better realize this utility model, in the initial installation state, the side of the limiting plate with the blunt opening is parallel to the axis of the through hole.

[0016] To better realize this utility model, the limiting plate has at least one bayonet on the side with the blunt opening.

[0017] Beneficial effects:

[0018] This invention utilizes an installation plate with at least two limiting plates and an adjusting component. First, a drilling or cutting device is used to create grooves in the honeycomb panel to accommodate the direct insertion of the installation plate and limiting plates. Then, at least two limiting plates are inserted into the grooves and forcefully pushed directly into the honeycomb panel until the installation plate is completely embedded in the groove. At this point, the adjusting component is gradually screwed in, applying pressure to one corner of the limiting plate. This creates a torque on the limiting plate around the hinge shaft, causing it to expand into a figure-eight shape and embed itself in the honeycomb panel. The connector is then stably installed. However, the adjusting components on the two installation plates have different lengths; the bolt head of the longer adjusting component protrudes from the installation plate, while the shorter one is hidden within it. The bolt head of the longer adjusting component is detachably snapped into the other installation plate, thus completing the honeycomb panel splicing. The operation is simple and convenient, and after installation, there are no holes or screws on the surface, resulting in a clean and aesthetically pleasing appearance. Attached Figure Description

[0024] Example

[0025] like Figures 1-2As shown, the honeycomb panel non-perforated connector includes a mounting plate 1. One end of the mounting plate 1 has at least one through groove 2. Two limiting plates 3 are symmetrically hinged to the at least one through groove 2 via two hinge shafts 21, and the hinge shafts 21 are far from the center of the through groove 2. The mounting plate 1 has a through hole 4 that passes through the through groove 2. At least one corner of the limiting plate 3 extends to the axis of the through hole 4. An adjusting member 5 that abuts against the limiting plate is provided in the through hole 4. The adjusting member 5 adopts a bolt structure. The two limiting plates 3 are adjustablely embedded in the honeycomb panel 14 through the adjusting member 5. Since the adjusting member 5 and the limiting plate 3 are the main force-bearing components, the adjusting member 5, the limiting plate 3 and the hinge shaft 21 connected to the through groove 2 are all made of metal or alloy materials to ensure that they have sufficient strength and hardness.

[0026] The working principle of this utility model can be summarized as follows:

[0027] First, install this connector on the two honeycomb panels 14 that need to be connected, such as... Figure 3 As shown, first, a drilling or cutting device is used to drill grooves in the honeycomb panel 14 to accommodate the direct insertion of the mounting plate 1 and the limiting plate 3. Then, the limiting plate 3 is inserted into the honeycomb panel 14 from the grooves until the mounting plate 1 is completely embedded in the grooves. Figure 4 As shown, the connectors installed in the two honeycomb panels 14 that need to be connected have adjusting members 5 of different lengths. One honeycomb panel 14 is equipped with a connector with a long adjusting member 5, the bolt head of the long adjusting member 5 protruding from the mounting plate 1. The other honeycomb panel 14 is equipped with a connector with a short adjusting member 5, the short one being hidden in the mounting plate 1.

[0028] After embedding the mounting plate 1, the limiting plate 3, and the bolts into the honeycomb plate 1, the adjusting piece 5 is gradually screwed in and pressure is applied to one corner of the limiting plate 3, forming a torque on the limiting plate 3 with the hinge shaft as the rotation axis. This torque causes the two limiting plates 3 to gradually expand into a figure-eight shape and gradually embed into the honeycomb plate 14. When the limiting plate 3 receives tension, the figure-eight expanding limiting plate 3 will form a stable connection under the obstruction of the honeycomb plate 1. Finally, the bolt head of the long adjusting piece 5 is detachably snapped into another mounting plate 1, thus completing the splicing of the honeycomb plate 14.

[0029] Preferably, the mounting plate 1 has a groove 6 at the end away from the limiting plate 3, and the width of the groove 6 is not less than the bolt head diameter of the adjusting member 5; a partition 7 parallel to the bottom surface is provided in the groove 6, and the distance between the partition 7 and the bottom surface of the groove 6 is equal to the maximum thickness of the bolt head of the adjusting member 5; the partition 7 has a U-shaped notch 8, the width of the U-shaped notch 8 is equal to the thread diameter of the adjusting member 5, and the inlet end of the U-shaped notch 8 has a V-shaped structure. After the connecting members with adjusting members 5 of different lengths are installed on the two honeycomb panels 14 to be connected (e.g. Figure 2As shown, the mounting plate 1 of the connector equipped with the long adjusting member 5 may not have a sliding groove 6 and a partition 7. The bolt head of the long adjusting member 5 is inserted into the end of the sliding groove 6 without the partition 7, and then moved towards the end with the partition 7. The bolt head will be embedded in the gap between the partition 7 and the bottom surface of the sliding groove 6, and the threaded rod will be embedded in the U-shaped notch 8. The V-shaped structure is more conducive to automatically correcting the insertion position of the threaded rod, thus forming a connection. When disassembly is required, it can be moved in the opposite direction.

[0030] Preferably, the mounting plate 1 has mounting openings 9 extending through two opposite sides. A nut 10 adapted to the adjusting member 5 is provided in the mounting opening 9. The adjusting member 5 can be adjusted to move within the through hole 4 by means of the nut 10. A fixing block 11 is provided in the mounting opening 9. The fixing block 11 has a slot 12 adapted to the nut 10. By setting the nut 10, the adjusting member 5 is rotated and positioned, so that it can move axially and be limited and fixed after moving to a certain position, thereby making the connector stably embedded in the honeycomb plate 14.

[0031] Preferably, each of the two limiting plates 3 in each through groove 2 is fitted with an elastic reset ring 13 close to the mounting plate 1. Since the two limiting plates 3 are hinged in the through groove 2, they can rotate freely. In order to ensure that the connector is not damaged when not in use, it is fixed by the elastic reset ring 13. At the same time, it is also convenient for the two limiting plates 3 to be brought together during installation, which is more conducive to insertion into the honeycomb plate 14.

[0032] Preferably, the limiting plate 3 has at least one acute angle 301. This acute angle 301 design allows the limiting plate 3 to be inserted into the honeycomb panel 14 more easily. The two intersecting portions of the acute angle 301 each have a cutting edge 302 and a blunt edge 303. When the limiting plate 3 is inserted into the honeycomb panel 14, the cutting edge 302 is the primary stress point, and its structure allows the limiting plate 3 to easily insert into the honeycomb panel 14 and reach the designated position. However, when the two panels are connected, the connector is mainly subjected to tensile force, and the blunt edge 303 is the primary stress point. The blunt edge 303 design increases the contact area between the limiting plate 3 and the honeycomb panel 14, effectively securing the plate.

[0033] Preferably, in the initial installation state, the side of the limiting plate 3 with the blunt end 303 is parallel to the axis of the through hole 4. The less resistance the limiting plate 3 receives during insertion into the honeycomb panel 14, the better. Therefore, when the side with the blunt end 303 is parallel to the axis of the through hole 4, there is no resistance to the insertion of the limiting plate 3. The resistance mainly comes from the cutting edge 302, which itself has a sharp characteristic and can be easily inserted into the honeycomb panel 14.

[0034] Preferably, the limiting plate 3 has at least one latch 304 on the side with the blunt opening 303. When the two plates are connected together, the connector is mainly subjected to tensile force. At this time, the force is mainly on the blunt opening 303. The design of the blunt opening 303 increases the contact area between the limiting plate 3 and the honeycomb plate 14, which can play an effective fixing role. However, the blunt opening 303 is always a slope, which inevitably has a tendency to slide against the internal partition 7 of the honeycomb plate 14. However, by designing multiple latches 304, the multiple latches 304 will form an effective latch with the honeycomb partition 7 inside the honeycomb plate 14, so that the connector can always be stably and firmly embedded in the honeycomb plate 14.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
