Description

Technical Field

[0001] The utility model relates to the technical field of furniture assembly accessories, in particular to an invisible furniture connector. Background Art

[0002] With the development of modular furniture assembly, people are increasingly inclined to purchase furniture components and then assemble them. This minimizes the constraints on furniture selection caused by weight and size restrictions on elevators and entrance doors. Modularity also makes it easier to transport and prevents damage to furniture caused by bumps and scrapes during transportation. The prerequisite for the development of modular furniture assembly is a variety of furniture connectors.

[0003] Currently, the two main types of metal connectors commonly used in panel furniture on the market are eccentric connectors and invisible sliding connectors. Eccentric connectors, commonly known as three-in-one fasteners, consist of an embedded nut, a connecting rod, and an eccentric nut. The connection method is to embed the embedded nut in panel A, then screw in the connecting rod, which is then inserted into the mounting hole of panel B. Finally, the eccentric nut is tightened by tightening the connecting rod to connect the two panels. The main disadvantage of this connection structure is that the eccentric nut is visible at all connection points of the furniture, affecting its aesthetics.

[0004] The invisible sliding buckle connector consists of a sliding buckle and a snap screw. The connection method is to fix the sliding buckle and snap screw to the sliding buckle groove of plate A and the fixing hole of plate B, respectively. Then, the plates are pushed in parallel directions so that the sliding buckle and snap screw move relative to each other to reach the connection point, thus completing the connection between the two plates. This connection method can hide the connector within the plate, which can make the furniture appearance more consistent and beautiful compared to eccentric connections. However, its main disadvantage is that it requires high furniture assembly technology. At the same time, due to the high degree of fit between the sliding buckle and the snap screw, it is generally necessary to use a tool such as a hammer to strike the plate from the side in parallel to force the snap screw into the sliding buckle. However, since the position of the snap screw and the sliding buckle can easily shift when striking from the side in parallel, it is difficult for one person to take into account the fixing of the connection point, holding the plate being struck steady, and holding the hammer, resulting in low assembly efficiency. Utility Model Content

[0005] In view of the defects of the prior art, the utility model provides a nail-button invisible metal furniture connector with a simple structure, more reasonable design, more convenient assembly operation, higher assembly efficiency, and the ability to maintain the consistency and aesthetics of furniture.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a nail-button invisible metal furniture connector, including a snap fastener, characterized in that: the snap fastener has a base plate and a buckle tongue extending relatively from the base plate and having rigidity, the gap between the buckle tongues forms a buckle opening, and the buckle cavity is surrounded by the buckle tongue and the base plate; it also includes a nail fastener, the nail fastener is a nail-shaped structure, which has a nail cap and a nail rod, and the tail end of the nail rod has a nail tip; the outer size of the nail cap is larger than the buckle opening width and smaller than the buckle cavity width, so that the nail cap can be clamped by the buckle tongue after sliding into the buckle cavity to form a buckled fixed structure.

[0007] Furthermore, two side walls are provided on the bottom plate in the longitudinal direction, and the buckle tongues extend relatively from the ends of the side walls toward the middle.

[0008] Furthermore, the two buckle tongues extend toward the middle to form a straight angle structure to achieve the fastening of the nail cap, that is, the buckle tongues and the side walls form an L-shaped structure.

[0009] Furthermore, a screw hole is provided near each end of the bottom plate, and the entire fastener is assembled and fixed in the mounting groove on the end face of the plate by screws; the two side walls and the buckle tongue are located between the two screw holes to reserve space for the fastener to come out and adjustment margin.

[0010] Furthermore, the height of the nail cap of the fastener is consistent with the inner height of the button cavity, so that the nail cap is clamped in the button cavity.

[0011] Furthermore, the nail rod is twisted into a twisted structure by twisting the hexagonal opposite-side material so that the contact surface between the nail rod and the plate forms a gripping structure that can generate an interactive force to enhance the nail holding force; the diameter of the nail rod is consistent with the width of the buckle mouth so that the nail fastener and the clip remain perpendicular.

[0012] Preferably, the entire clip is an integral structure, which is made of manganese steel with a black electroplated surface. The entire nail fastener is an integral structure, which is made of carbon steel with a galvanized surface.

[0013] This utility model utilizes a nail-button connection principle, with the fasteners being nailed directly into the furniture. This makes assembly more convenient and quicker than a slide-button connection, allowing for one-person operation and improved assembly efficiency. Furthermore, the nail-button connectors are adapted to current panel furniture production process requirements, eliminating the need for major technical modifications to existing production equipment and processes. Simply adjusting the connectors according to their technical parameters simplifies implementation. Furthermore, the assembly principle used in this utility model for furniture is the same as that of slide-button connectors, with both being concealed within the panels. This ensures that the finished furniture maintains its aesthetic appearance without compromising its appearance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In this embodiment, refer to Figure 1-Figure 3 The described nail-button invisible metal furniture connector includes a snap fastener 1, which has a base plate 11 and a buckle tongue 13 extending relatively from the base plate 11 and having rigidity, a gap between the buckle tongues 13 forming a buckle opening 14, and a buckle cavity 15 formed under the buckle tongues 13; and also includes a nail fastener 2, which has a nail rod 22 and a nail cap 23; the width of the buckle opening 14 is smaller than the outer diameter of the nail cap 23, and the width of the buckle cavity 15 is larger than the outer diameter of the nail cap 23, so that the nail cap 23 can be clamped by the buckle tongue 13 after sliding into the buckle cavity 15 to form a combined fixed structure.

[0022] The bottom plate 11 is provided with two side walls 12 in the longitudinal direction, and the top ends of the side walls 12 form relatively extending buckle tongues 13 toward the middle. The buckle tongues 13 extend horizontally toward the middle to form an L-shaped structure with the side walls 12 to clamp the nail rod 22 and fasten the nail cap 23.

[0023] The fastener 2 is a nail-shaped structure, with the outer diameter of the nail cap 23 at the end being larger than the width of the buckle opening 14 to facilitate its engagement with the buckle tongue 13. The outer diameter of the nail shank 22 is equal to the width of the buckle opening 14 to facilitate its engagement with the buckle tongue 13. The nail shank 22 is twisted into a hexagonal, equilateral material, forming a twisted outer wall. This creates a force between the nail shank 22 and the panel contact surface, enhancing the grip. Of course, the fastener 2 can also be configured with various lengths or surface finishes, such as threaded or barbed, depending on the characteristics of the assembly material.

[0024] Reference Figure 4-Figure 6During assembly, the clip 1 is inserted and fixed into the mounting groove 31 on the end face of the A plate 3. The nail 2 slides into the buckle cavity 15 so that it is centered on the clip 1. Align the guide hole 41 on the end face of the B plate 4 with the nail tip 21. Press the B plate 4 firmly or hit the end face of the B plate 4 with a rubber hammer to move the B plate 4 vertically relative to the A plate 3, so that the nail rod 22 is nailed into the B plate 4 through the guide hole 41.

[0025] Since the two buckle tongues 13 are formed into a straight L-shaped structure, the buckle tongues 13 can not only firmly fasten the nail cap 23, but also stabilize the sliding direction of the nail rod 22 and enable the buckle tongues 13 to clamp the nail rod 22.

[0026] A screw hole 16 is located near each end of the base plate 11, allowing the entire fastener 2 to be assembled and secured to the mounting slot 31 on the end face of the A plate 3. The two side walls 12 and the latch tongue 13 are located between the two screw holes 16, leaving space for the nail cap 23 to escape and allowing for adjustment, facilitating disassembly and adjustment. To disassemble, push or tap one end of the B plate 4, causing it to move parallel to the A plate 3, releasing the nail cap 23 from the latch cavity 15 of the fastener 1, and the two plates can be separated. If there is a slight misalignment between the two plates during assembly, alignment can be adjusted as described above.

[0027] The entire clip 1 is an integral structure, made of manganese steel with a black electroplated surface. The clip 1 made of manganese steel can provide the buckle tongue 13 with a sufficiently high structural strength, making it difficult to break and capable of stably buckling the nail cap 23 and clamping the nail rod 22.

[0028] The entire fastener 2 is an integral structure, made of carbon steel and galvanized on the surface.

[0029] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
