Description

Technical Field

[0001] The present invention relates to the technical field of furniture connector equipment, in particular to a magnetic return device for invisible connectors of parent-child furniture. Background Art

[0002] Three-in-one connectors are one of the most common installation methods for panel furniture. They can be assembled and disassembled multiple times without the need for adhesives. As people's aesthetic requirements for custom furniture grow, so too do the demands for connectors. Consequently, there's a growing demand for invisible connectors. These connectors conceal the connection holes during assembly, leaving the furniture virtually invisible and aesthetically pleasing. They're also quick and easy to install.

[0003] Our company's disclosed patent number is 2020101503662, an invention patent for a crescent-shaped detachable side panel connecting mother-and-child parts. By setting a plurality of reinforcement ribs evenly distributed on the outside of the fixed plate, after the user puts the fixing part into the crescent groove, the reinforcement ribs are in contact with the upper and lower ends of the crescent groove, so that the fixing part is firmly fixed in the groove to prevent the fixing part from sliding in the groove, thereby making the connection between the plates more stable after the connecting part is installed. However, in daily use, due to the shaking or pulling of external furniture and the toughness of the connecting column's own material, the connecting column is prone to tilt, making it difficult for the connecting buckle to continuously fasten the surface of the connecting rib, causing the furniture connection to loosen, etc. Therefore, a magnetic return device for invisible connectors of mother-and-child furniture is proposed to solve problems such as loose furniture connection caused by the tilt of the connecting column under force.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a return member. When the user snaps the subassembly into the mother assembly, the connecting post presses against the top of the return rod. The return rod is forced downward, the return spring contracts, and the connecting spring stretches. When the connecting buckle on the outside of the connecting post engages the connecting rib, the connecting post slides to the side of the return rod. The return rod rebounds upward due to the extension of the return spring and the contraction of the connecting spring until the retaining ring is pressed against the bottom end of the upper plate. At this time, the side of the connecting post abuts against the side of the connecting post away from the connecting buckle, pressing the connecting post tightly. This prevents the connecting post from tilting due to shaking or pulling of external furniture and the toughness of the connecting post's own material, which could make it difficult for the connecting buckle to maintain its grip on the surface of the connecting rib and cause the furniture connection to loosen. This enhances the stability of the connecting parts, making the connection between the furniture more secure, and prevents loosening of the connecting parts due to external forces, thereby enhancing the practicality of the device.

[0031] Working principle: When using the present invention, it is necessary to have a simple understanding of the structure of the present invention. The user installs the return spring 33 into the outside of the return rod 32, and the top of the return spring 33 presses against the limiting ring 322. The return rod 32 is aligned with the lower through hole 3111 and installed. The limiting washer 34 is aligned with the slot 321 and installed. Due to the action of the return spring 33, the top of the limiting washer 34 fits the bottom end of the lower plate 311. The upper through hole 351 on the upper plate 35 is aligned with the upper part of the return rod 32, and the upper plate 35 is inserted. The connecting spring 37 is aligned with the lower through hole 3111. The connecting rod 36 is inserted, the top of the connecting spring 37 is against the bottom end of the connecting rod limiting ring 361, and the connecting rod 36 is installed in alignment with the upper connecting hole 3531 and the lower connecting hole 3121. The connecting rod washer 38 is installed into the connecting rod slot 362. Under the action of the connecting spring 37, the upper surface of the connecting rod washer 38 is tightly attached to the bottom end of the lower get off work 311. The return part 3 is assembled. The user puts the return part 3 into the pre-made installation groove of the furniture, puts the mother part 2 in facing the return part 3, and puts the child part 1 into the pre-made installation groove of another furniture. When the user buckles the sub-assembly 1 into the mother part 2, the connecting post 11 is pressed to the top of the return rod 32, and the return rod 32 is forced to move downward, the return spring 33 contracts, and the connecting spring 37 stretches. When the connecting buckle 111 on the outside of the connecting post 11 is buckled onto the connecting rib 211, the connecting post 11 slides to the side of the return rod 32, and the return rod 32 is rebounded by the rebound action of the return spring 33 and the contraction action of the connecting spring 37 until the limiting ring 322 is aligned with the upper The bottom end of plate 35 is pressed tightly, and the side surface of connecting post 11 is then pressed against the side of connecting post 11 away from connecting buckle 111, thereby pressing connecting post 11 tightly. This prevents connecting post 11 from tilting due to external furniture shaking or pulling, as well as the toughness of the connecting post 11 itself. This could make it difficult for connecting buckle 111 to maintain its grip on the surface of connecting rib 211, which could cause the furniture connection to loosen. This enhances the stability of the connecting parts, making the connection between the furniture more secure, and prevents loosening of the connecting parts due to external forces, thereby enhancing the practicality of the device. The lower plate 311 and the removal side plate 3112 are made of a material that attracts magnets. During disassembly, a magnet is placed on or behind the lower plate 311. Due to the principle of magnetic attraction, it is moved backward. The magnet attracts the lower plate 311 and the removal side plate 3112 to slide backward, simultaneously driving the return rod 32 downward until the return rod 32 is completely free of the side of the connecting buckle 111. Under the condition of tension, the sub-component 1 and the mother component 2 can be effectively separated, ensuring the practicality of the device.
