Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, and particularly relates to an invisible furniture connector. Background Technique
[0002] At present, the plate connectors of panel furniture in the furniture industry are basically installed and fixed in a three-in-one manner, playing a role in connecting and fixing the tensile force. The three-in-one connectors basically drill holes for three-in-one embedded rubber particles on the side plates. Now, the requirements for customized furniture are getting higher and higher. For the sake of more beauty, invisible furniture connectors have emerged. As the prior art, Chinese Patent CN218294078U proposes a new type of invisible furniture connector, which still has the following disadvantages: In this technical solution, when the layer board is connected to the side board, the layer board is pushed inward, so that the chute of the connecting fastener clamps the flat head fast thread, making the side board and the layer board clamped. However, when subjected to a large external force and vibration, the chute and the flat head fast thread may loosen and then slide. Because the outer end of the chute is open, the layer board may be forced to slide outward and loosen from the side board, and may even fall off. Therefore, there is still room for improvement. Content of the Utility Model
[0003] The purpose of the utility model is to provide an invisible furniture connector to solve the problems raised in the above background technique.
[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: An invisible furniture connector includes a connecting fastener, a self-tapping screw, a flat head fast thread, a layer board, a card slot and a side board. The connecting fastener is integrally in a "C" shape, and there are first through holes on its two folded edges, and a chute is arranged on its upper end surface; there are card slots on both end surfaces of the layer board; the connecting fastener is installed in the card slot through a self-tapping screw, and a flat head fast thread is installed on the side board at a position corresponding to the card slot on the layer board. The layer board installed with the connecting fastener is installed on the side board through the cooperation of the connecting fastener and the flat head fast thread. It also includes a limiting component, which includes a connecting piece, a spring and a limiting block. An extension slot is opened on one side in the card slot, the connecting piece is provided with a second through hole, the connecting piece is installed in the extension slot through a self-tapping screw, one end of the spring is fixed to the connecting piece, and the other end is fixed with a limiting block. The limiting block is slidably connected to the side wall of the extension slot, and the limiting block has magnetism; it also includes a magnet for adsorbing the limiting block.
[0005] Using the above technical solution, when the shelf and side plate are connected, the magnet is placed above the side plate at the corresponding position of the extension groove. The magnet attracts the limiting block, and the sliding magnet drives the limiting block to slide. The limiting block compresses the spring and moves inward into the extension groove. Then, the opening of the slide groove of the connecting fastener is aligned with the flat-head quick-release thread, and the shelf is pushed inward so that the flat-head quick-release thread engages with the slide groove, thereby connecting the side plate and the shelf. Then, the magnet is removed, the spring returns to its original position and pushes the limiting block outward. The limiting block blocks the position of the slide groove opening. When subjected to large external forces and vibrations, if the slide groove and the flat-head quick-release thread become loose, the flat-head quick-release thread is blocked by the limiting block, and the shelf may slide outward under force, making it less likely for the side plate to loosen, thereby improving the stability of the connection. When disassembly is required, the same principle applies: the sliding magnet drives the limiting block to slide, thereby releasing the obstruction of the flat-head quick-release thread.
[0006] As a further optimization of this utility model, the side of the limiting block near the connecting groove is set as a plane, and the side away from the connecting groove is set as an arc surface.
[0007] Using the above technical solution, when the flat-head quick thread connects to the slide, if it is blocked by the limiting block, the flat-head quick thread can also push the limiting block towards the inside of the extension groove through the arc surface, thereby ensuring that the flat-head quick thread and the slide can be smoothly engaged.
[0008] As a further optimization of this utility model, the inner wall of the extension groove is provided with a guide groove, and the limiting block is provided with a slider on the side near the sliding groove, and the slider is slidably connected to the guide groove.
[0009] The beneficial effects of this utility model are as follows: When the shelf and the side plate are connected, the magnet is placed above the side plate at the corresponding position of the extension groove. The magnet attracts the limiting block, and the sliding magnet drives the limiting block to slide. The limiting block compresses the spring and moves towards the inside of the extension groove. Then, the opening of the slide groove of the connecting fastener is aligned with the flat-head quick-release tooth, and the shelf is pushed inward so that the flat-head quick-release tooth and the slide groove are engaged, thereby connecting the side plate and the shelf. Then, the magnet is removed, the spring returns to its original position and pushes the limiting block outward. The limiting block blocks the position of the slide groove opening. When subjected to large external force and vibration, if the slide groove and the flat-head quick-release tooth become loose, the flat-head quick-release tooth is blocked by the limiting block, and the shelf may be forced to slide outward and the side plate is not easy to loosen, thereby improving the stability of the connection. When disassembly is required, the same principle applies. The sliding magnet drives the limiting block to slide, thereby releasing the obstruction of the flat-head quick-release tooth.

Specific embodiments
[0013] This specific embodiment is only an explanation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
[0014] See the appendix Figure 1-2 , this embodiment disclosed by the present utility model is further provided with: a furniture hidden connector, including a connecting fastener 4, a self-tapping screw 3, a flat head quick thread 5, a shelf 2, a card slot 21 and a side plate 1. The connecting fastener 4 is integrally in a "C" shape, with first through holes 42 provided on its two folded edges, and a sliding slot 41 provided on its upper end surface; card slots 21 are provided on both end surfaces of the shelf 2; the connecting fastener 4 is installed in the card slot 21 through a self-tapping screw 3, and a flat head quick thread 5 is installed on the side plate 1 at a position corresponding to the card slot 21 on the shelf 2. The shelf 2 installed with the connecting fastener 4 is installed on the side plate 1 through the cooperation of the connecting fastener 4 and the flat head quick thread 5;
[0015] It further includes a limiting component. The limiting component includes a connecting piece 6, a spring 71 and a limiting block 72. An extension slot 22 is opened on one side in the card slot 21. The connecting piece 6 is provided with a second through hole 61. The connecting piece 6 is installed in the extension slot 22 through a self-tapping screw 3. One end of the spring 71 is fixed to the connecting piece 6, and the other end is fixed with a limiting block 72. The limiting block 72 is slidably connected to the side wall of the extension slot 22. Specifically, a guiding slot 221 is opened on the inner wall of the extension slot 22. A slider 711 is provided on one side of the limiting block 72 close to the sliding slot 41. The slider 711 is slidably connected to the guiding slot 221.
[0016] The limiting block 72 is magnetic; it further includes a magnet 8 for adsorbing the limiting block 72. Further, one side of the limiting block 72 close to the connecting slot is set as a plane, and the side far from the connecting slot is set as an arc surface.
[0017] The principle of this utility model is as follows: When the shelf 2 is connected to the side plate 1, the magnet 8 is placed above the side plate 1 at the corresponding position of the extension groove 22. The magnet 8 attracts the limiting block 72. The sliding magnet 8 drives the limiting block 72 to slide. The limiting block 72 slides through the slider 711 and the guide groove 221. At the same time, the limiting block 72 squeezes the spring 71 and moves it towards the inside of the extension groove 22. Then, the opening of the slide groove 41 of the connecting fastener 4 is aligned with the flat-head quick tooth 5. The shelf 2 is then pushed inward so that the flat-head quick tooth 5 is engaged with the slide groove 41, thereby connecting the side plate 1 and the shelf 2. If the flat-head quick tooth 5 is still partially blocked by the limiting block 72, the flat-head quick tooth 5 can also push the limiting block 72 towards the inside of the extension groove 22 through the arc surface, thereby ensuring that the flat-head quick tooth 5 and the slide groove 41 can be engaged smoothly.
[0018] Then remove magnet 8, spring 71 returns to its original position and pushes limit block 72 outward. Limit block 72 blocks the opening of slide groove 41. When subjected to large external force and vibration, if slide groove 41 and flat-head quick tooth 5 become loose, flat-head quick tooth 5 will be blocked by limit block 72. The shelf 2 may be forced to slide outward and the side plate 1 will not easily become loose, thereby improving the stability of the connection.
[0019] Similarly, when disassembly is required, the sliding magnet 8 drives the limiting block 72 to slide, thereby releasing the obstruction to the flat-head fast tooth 5.
[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
